    The problem of stabilization/pole placement under structural constraints of large scale linear systems is discussed. The existence of a solution to this problem is expressed in terms of fixed modes. The aim is to provide a bibliographic survey of the available results concerning the fixed modes (characterization, elimination, control structure selection to avoid them, control design in their absence) and to present the author's contribution to this problem which can be summarized by the use of the mode sensitivity concept to detect or to avoid them, the use of vibrational control to stabilize them, and the addition of parametric robustness considerations to design an optimal decentralized robust control.

    The Carbon Dioxide Reduction Assembly (CRA) on the International Space Station (ISS) has been operational since 2010. The CRA uses a Sabatier reactor to produce water and methane by reaction of the metabolic CO2 scrubbed from the cabin air and the hydrogen byproduct from the water electrolysis system used for metabolic oxygen generation. Incorporating the CRA into the overall air revitalization system has facilitated life support system loop closure on the ISS reducing resupply logistics and thereby enhancing longer term missions. The CRA utilizes CO2 which has been adsorbed in a 5A molecular sieve within the Carbon Dioxide Removal Assembly, CDRA. There is a potential of compounds with molecular dimensions similar to, or less than CO2 to also be adsorbed. In this fashion trace contaminants may be concentrated within the CDRA and subsequently desorbed with the CO2 to the CRA. Currently, there is no provision to remove contaminants prior to entering the Sabatier catalyst bed. The risk associated with this is potential catalyst degradation due to trace organic contaminants in the CRA carbon dioxide feed acting as catalyst poisons. To better understand this risk, United Technologies Aerospace System (UTAS) has teamed with MSFC to investigate the impact of various trace contaminants on the CRA catalyst performance at relative ISS cabin air concentrations and at about 200/400 times of ISS concentrations, representative of the potential concentrating effect of the CDRA molecular sieve. This paper summarizes our initial assessment results.

    The Sabatier Methanation Reactor technology is of vital importance to the success of the human and robotic exploration program. In order to achieve an affordable program, the logistics supply to support the mission must be minimized to the fullest extent possible. One area of potential reduction with high return on investment is the closure of life support loops, particularly oxygen and water. The Sabatier system accomplishes this by utilizing hydrogen and carbon dioxide, waste products from the life support system, to produce water and methane. The recovered water is then recycled back into the life support system to provide oxygen; while the methane can be used for propulsion, or can be broken down further to recover the hydrogen. This technology is applicable not only to transit phases of exploration, but surface habitats as well as in-situ propellant production. The Sabatier Reactor system has been developed for ground based demonstration experiments extensively over the past 30 years. Over the past three years, NASA has funded development of the Sabatier Carbon Dioxide Reduction Assembly (CRA) for use on the ISS. Currently this system is at TRL 5 and it is expected that the system will be flown on the ISS as a flight experiment, The purpose of the flight experiment is to integrate the Sabatier CRA into a synchronized system with the oxygen generation system and the carbon dioxide concentrator. The flight experiment will verify the integration of the different systems working together plus it will verify the capability of the system to operate, and effectively separate its products in a micro-gravity environment. Subsequent to design validation, the flight experiment can remain onboard the ISS providing valuable water to offset logistics re-supply requirements. Some of the challenges facing the development of the Sabatier system include handling vibration induced particulates, microgravity phase separation and containment of hazardous gases. Plans for

    1998-01-01

    As manned space missions become longer and go farther away (i.e., Mars missions), the cost of resupply missions becomes substantial and even impractical. In order to reduce the logistics penalty for air revitalization in manned spacecraft, breathing oxygen (O2) must be recovered from metabolic carbon dioxide (CO2). The Sabatier CO2 reduction system is a key component of an integrated air revitalization system. The heart of the Sabatier system is the chemical catalyst bed that reacts carbon dioxide with hydrogen to form methane and water. Product water from a Sabatier subsystem would positively affect the current International Space Station (ISS) water balance and Mars missions would also benefit from the use of product methane as a propellant. This article focuses on the potential benefits of using the Sabatier subsystem for ISS and potential Mars mission applications. PMID:11871449

    Highly active Ru/TiO2 catalysts for Sabatier reaction have been developed. The catalysts have shown to be stable under repeated shutting down/startup conditions. When the Ru/TiO2 catalyst is coated on the engineered substrate Fe-CrAlY felt, activity enhancement is more than doubled when compared with an identically prepared engineered catalyst made from commercial Degussa catalyst. Also, bimetallic Ru-Rh/TiO2 catalysts show high activity at high throughput.

    The utilization of CO2 to produce life support consumables, such as O2 and H2O, via the Sabatier reaction is an important aspect of NASA s cabin Atmosphere Revitalization System and In-Situ Resource Utilization architectures for both low-earth orbit and long-term manned space missions. In the current International Space Station (ISS) and other low orbit missions, metabolically-generated CO2 is removed from the cabin air and vented into space, resulting in a net loss of O2. This requires a continuous resupply of O2 via water electrolysis, and thus highlights the need for large water storage capacity. For long-duration space missions, the amount of life support consumables is limited and resupply options are practically nonexistent, thus atmosphere resource management and recycle becomes crucial to significantly reduce necessary O2 and H2O storage. Additionally, the potential use of the Martian CO2-rich atmosphere and Lunar regolith to generate life support consumables and propellant fuels is of interest to NASA. Precision Combustion, Inc. (PCI) has developed a compact, lightweight Microlith(Registered TradeMark)-based Sabatier (CO2 methanation) reactor which demonstrates the capability of achieving high CO2 conversion and near 100% CH4 selectivity at space velocities of 30,000-60,000 hr-1. The combination of the Microlith(Registered TradeMark) substrates and durable, novel catalyst coating permitted efficient Sabatier reactor operation that favors high reactant conversion, high selectivity, and long-term durability. This paper presents the reactor development and performance results at various operating conditions. Additionally, results from 100-hr durability tests and mechanical vibration tests are discussed.

    A six-man, flight prototype carbon dioxide reduction subsystem for the SSP ETC/LSS (Space Station Prototype Environmental/Thermal Control and Life Support System) was developed and fabricated for the NASA-Johnson Space Center between February 1971 and October 1973. Component design verification testing was conducted on the Sabatier reactor covering design and off-design conditions as part of this development program. The reactor was designed to convert a minimum of 98 per cent hydrogen to water and methane for both six-man and two-man reactant flow conditions. Important design features of the reactor and test conditions are described. Reactor test results are presented that show design goals were achieved and off-design performance was stable.

    A preoprototype Sabatier CO2 Reduction Subsystem was successfully designed, fabricated and tested. The lightweight, quick starting reactor utilizes a highly active and physically durable methanation catalyst composed of ruthenium on alumina. The use of this improved catalyst permits a single straight through plug flow design with an average lean component H2/CO2 conversion efficiency of over 99% over a range of H2/CO2 molar ratios of 1.8 to 5 while operating with flows equivalent to a crew size of one person steadystate to 3 persons cyclical (equivalent to 5 persons steady state). The reactor requires no heater operation after start-up even during simulated 55 minute lightside/39 minute darkside orbital operation over the above range of molar ratios and crew loadings. The subsystem's operation and performance is controlled by a microprocessor and displayed on a nineteen inch multi-colored cathode ray tube.

    The kinetics of the Sabatier methanation reaction, the reduction of carbon dioxide with hydrogen to methane and water, was investigated for 58 percent nickel on kieselguhr catalyst and 20 percent ruthenium on alumina catalyst. Differential rate data from an experimental program were correlated with a power function rate equation both for forward and reverse reactions. The kinetic parameters of activation energy, frequency rate constant and reaction order were determined for the rate equation. The values of these parameters were obtained from an Arrhenius plot of the experimental differential rate data. Also the carbon monoxide side reaction effect was measured and included in the correlation of parameters. The reaction was found to fit the rate equation experimentally within the temperature range 421 K, where the reaction effectively begins, the 800 K where the reaction rate drops and departs from the rate equation form.

    2004-01-01

    The Sabatier Carbon Dioxide Reduction System (CRA) offers water recovery on a long duration space mission to reduce water resupply. Currently, NASA Johnson Space Center (JSC), NASA Marshall Space Flight Center (MSFC), Hamilton Sundstrand Space Systems International, Inc. (HSSSI), and Southwest Research Institute (SWRI) are working together to develop a Sabatier CRA for the International Space Station (ISS). This effort is being funded by the Office of Biological and Physical Research (Code U)/Advanced Life Support program which is administered by NASA JSC. The Sabatier CRA is the next step in closing the oxygen life support loop on future space missions. The Sabatier reaction combines the waste carbon dioxide (recovered from crew metabolism) with waste hydrogen (a byproduct of electrolysis to produce oxygen) to produce water and methane (CH4). On ISS, the methane would be vented overboard, however the methane can be utilized for propulsion during a planetary exploration mission. Based on a crew size of 7-equivalent people, the Sabatier CRA can produce as much a 2000 lb/year water. Use of the Sabatier CRA will significantly reduce the amount of water that needs to be resupplied to the ISS on a yearly basis, at a tremendous cost saving to the program. Additionally, by recycling this additional water, the Sabatier CRA enables additional launch capacity for science experiments to be brought up to the ISS. The NASA/Industry team noted above has been working to reduce technical risks associated with the Sabatier CRA system. To date the technical risks have been considerably reduced, bringing the Technology Readiness Level (TRL) from TRL 4 to TRL 5/6. In doing so, the team has developed the system schematic, system models, control scheme, produced engineering development unit (EDU) hardware, performed limited integration testing of the EDU's and verified system modeling through testing. Additionally, the system schematic has been evaluated for failure modes and hazards

    Brooks, Kriston P.; Hu, Jianli; Zhu, Huayang; Kee, Robert

    2007-02-01

    This paper describes the development of a microchannel-based Sabatier reactor for applications such as propellant production on Mars or space habitat air revitalization. Microchannel designs offer advantages for a compact reactor with excellent thermal control. This paper discusses the development of a Ru-TiO2 based catalyst using powdered form and its application and testing in a microchannel reactor. The resultant catalyst and microchannel reactor demonstrates good conversion, selectivity, and longevity in a compact device. A chemically reacting flow model is used to assist experimental interpretation and to suggest microchannel design approaches. A kinetic rate expression for the global Sabatier reaction is developed and validated using computational models to interpret packed-bed experiments with catalysts in powder form. The resulting global reaction is then incorporated into a reactive plug-flow model that considers flow within a microchannel reactor.

    2015-01-01

    State-of-the-art life support carbon dioxide (CO2) reduction technology is based on the Sabatier reaction where less than 50% of the oxygen required for the crew is recovered from metabolic CO2. The reaction produces water as the primary product and methane as a byproduct. Oxygen recovery is constrained by the limited availability of reactant hydrogen. This is further exacerbated when Sabatier methane (CH4) is vented as a waste product resulting in a continuous loss of reactant hydrogen. Post-processing methane with the Plasma Pyrolysis Assembly (PPA) to recover hydrogen has the potential to dramatically increase oxygen recovery and thus drastically reduce the logistical challenges associated with oxygen resupply. The PPA decomposes methane into predominantly hydrogen and acetylene. Due to the highly unstable nature of acetylene, a separation system is necessary to purify hydrogen before it is recycled back to the Sabatier reactor. Testing and evaluation of a full-scale Third Generation PPA is reported and investigations into metal hydride hydrogen separation technology is discussed.

    2014-01-01

    The utilization of CO2 to produce life support consumables, such as O2 and H2O, via the Sabatier reaction is an important aspect of NASA's cabin Atmosphere Revitalization System (ARS) and In-Situ Resource Utilization (ISRU) architectures for both low-earth orbit and long-term manned space missions. Carbon dioxide can be reacted with H2, obtained from the electrolysis of water, via Sabatier reaction to produce methane and H2O. Methane can be stored and utilized as propellant while H2O can be either stored or electrolyzed to produce oxygen and regain the hydrogen atoms. Depending on the application, O2 can be used to replenish the atmosphere in human-crewed missions or as an oxidant for robotic and return missions. Precision Combustion, Inc. (PCI), with support from NASA, has previously developed an efficient and compact Sabatier reactor based on its Microlith® catalytic technology and demonstrated the capability to achieve high CO2 conversion and CH4 selectivity (i.e., =90% of the thermodynamic equilibrium values) at high space velocities and low operating temperatures. This was made possible through the use of high-heat-transfer and high-surface-area Microlith catalytic substrates. Using this Sabatier reactor, PCI designed, developed, and demonstrated a stand-alone CO2 Reduction Assembly (CRA) test system for ground demonstration and performance validation. The Sabatier reactor was integrated with the necessary balance-of-plant components and controls system, allowing an automated, single "push-button" start-up and shutdown. Additionally, the versatility of the test system prototype was demonstrated by operating it under H2-rich (H2/CO2 of >4), stoichiometric (ratio of 4), and CO2-rich conditions (ratio of <4) without affecting its performance and meeting the equilibrium-predicted water recovery rates. In this paper, the development of the CRA test system for ground demonstration will be discussed. Additionally, the performance results from testing the system at

    Director Paul F. Bikle, seated at his desk at NASA's Flight Research Center (FRC) in 1959, the year of his appointment. The FRC became the Dryden Flight Research Center in 1976, after Paul's retirement. Paul F. Bikle became Director of the National Aeronautics and Space Administration's Flight Research Center at Edwards, California, on September 15, 1959, retaining that title until April 27, 1971, when he requested to be placed in an advisory role until his retirement on May 31, 1971. He was formerly technical director of the Air Force Flight Test Center at Edwards. During his nearly 12 years with NASA he was responsible for several major aeronautical research programs, including those involving the highly successful rocket-powered X-15, the supersonic XB-70, the fleet of wingless lifting bodies that contributed to development of the Space Shuttles, and the Lunar Landing Research Vehicle that paved the way for successful landings by Apollo astronauts on the moon's surface. Paul earned a Bachelor's degree in aeronautical engineering from the University of Detroit in 1939. He first worked for Taylorcraft Aviation Corporation in Ohio before beginning his government service career in 1940 at Wright Field, Ohio. In his first 20 years of civilian service in aeronautical engineering, he was author of more than 40 technical publications. Bikle was a veteran of 23 years of soaring. He established two world soaring records on February 25, 1961, achieving an altitude of 46,269 feet and a total-altitude-gained mark of 42,305 feet. Both marks were certified by the Soaring Society of America, National Aeronautic Association, and the Federation Aeronautique Internationale. Bikle held those records for sailplanes for more than 20 years. In July, 1962, Paul was awarded the NASA Medal for Outstanding Leadership. NASA cited him for his part in directing the successful X-15 flight operations and research activities. Paul was also a Fellow in the American Institute of Aeronautics and

    Accumulation and subsequent compression of carbon dioxide that is removed from the space cabin are two important processes involved in a closed-loop air revitalization scheme of the International Space Station (ISS). The 4-Bed Molecular Sieve (4BMS) of ISS currently operates in an open loop mode without a compressor. The Sabatier Engineering Development Unit (EDU) processes waste CO2 to provide water to the crew. This paper reports the integrated 4BMS, air-cooled Temperature Swing Adsorption Compressor (TSAC), and Sabatier EDU testing. The TSAC prototype was developed at NASA Ames Research Center (ARC). The 4BMS was modified to a functionally flight-like condition at NASA Marshall Space Flight Center (MSFC). Testing was conducted at MSFC. The paper provides details of the TSAC operation at various CO2 loadings and corresponding performance of the 4BMS and Sabatier.

    The utilization of CO2 to produce (or recycle) life support consumables, such as O2 and H2O, and to generate propellant fuels is an important aspect of NASA's concept for future, long duration planetary exploration. One potential approach is to capture and use CO2 from the Martian atmosphere to generate the consumables and propellant fuels. Precision Combustion, Inc. (PCI), with support from NASA, continues to develop its regenerable adsorber technology for capturing CO2 from gaseous atmospheres (for cabin atmosphere revitalization and in-situ resource utilization applications) and its Sabatier reactor for converting CO2 to methane and water. Both technologies are based on PCI's Microlith(R) substrates and have been demonstrated to reduce size, weight, and power consumption during CO2 capture and methanation process. For adsorber applications, the Microlith substrates offer a unique resistive heating capability that shows potential for short regeneration time and reduced power requirements compared to conventional systems. For the Sabatier applications, the combination of the Microlith substrates and durable catalyst coating permits efficient CO2 methanation that favors high reactant conversion, high selectivity, and durability. Results from performance testing at various operating conditions will be presented. An effort to optimize the Sabatier reactor and to develop a bench-top Sabatier Development Unit (SDU) will be discussed.

    This volume is devoted to a reappraisal of the philosophy of Paul Feyerabend. It has four aims. The first is to reassess his already well-known work from the 1960s and 1970s in light of contemporary developments in the history and philosophy of science. The second is to explore themes in his neglected later work, including recently published and previously unavailable writings. The third is to assess the contributions that Feyerabend can make to contemporary debate, on topics such as perspectivism, realism, and political philosophy of science. The fourth and final aim is to reconsider Feyerabend's place within the history of philosophy of science in the light of new scholarship. PMID:27269258

  1. Rotary Drum Separator and Pump for the Sabatier Carbon Dioxide Reduction System

    NASA Technical Reports Server (NTRS)

    2005-01-01

    A trade study conducted in 2001 selected a rotary disk separator as the best candidate to meet the requirements for an International Space Station (ISS) Carbon Dioxide Reduction Assembly (CRA). The selected technology must provide micro-gravity gasfliquid separation and pump the liquid from 10 psia at the gasfliquid interface to 18 psia at the wastewater bus storage tank. The rotary disk concept, which has pedigree in other systems currently being built for installation on the ISS, failed to achieve the required pumping head within the allotted power. The separator discussed in this paper is a new design that was tested to determine compliance with performance requirements in the CRA. The drum separator and pump @SP) design is similar to the Oxygen Generator Assembly (OGA) Rotary Separator Accumulator (RSA) in that it has a rotating assembly inside a stationary housing driven by a integral internal motor. The innovation of the DSP is the drum shaped rotating assembly that acts as the accumulator and also pumps the liquid at much less power than its predecessors. In the CRA application, the separator will rotate at slow speed while accumulating water. Once full, the separator will increase speed to generate sufficient head to pump the water to the wastewater bus. A proof-of- concept (POC) separator has been designed, fabricated and tested to assess the separation efficiency and pumping head of the design. This proof-of-concept item was flown aboard the KC135 to evaluate the effectiveness of the separator in a microgravity environment. This separator design has exceeded all of the performance requirements. The next step in the separator development is to integrate it into the Sabatier Carbon Dioxide Reduction System. This will be done with the Sabatier Engineering Development Unit at the Johnson Space Center.

    Ever since the dawn of the 20th Century there has been a universal consensus that Alphonse Mucha launched the sensation that became known as Art Nouveau. This event was associated with the appearance of his Gismonda poster promoting the Sarah Bernhardt play of that name in Paris in 1894. At an estate sale in 1954 a small collage bearing a likeness of Mucha's Gismonda was offered. It had been fabricated by gluing slivers cut from sixty postage stamps to a 20cm ceramic tile. Digital computer image enhancement was applied to the collage design, initials on a walking stick from the same estate collection, and the Mucha poster. These geometrical analyses revealed that the collage is more detailed than the Mucha "original". This led to our hypothesis that the famous poster was a hasty photographic plagiarism of the intricate ceramic-tile collage. Image analyses of the initials on the companion walking stick revealed conformity with the famous enigmatic "P GO" monogram of Paul Gauguin. We conclude that Gauguin rather than Mucha created the Gismonda composition. Historical evidence suggests that, while Gauguin was in Brittany recovering from injuries sustained in a fistfight, Annah la Javanese stole his possessions and took them to Paris where her next lover, Mucha, copied the collage and presented it as his original poster design.

    This study aimed to investigate the feasibility of substitute natural gas (SNG) generation using biogas from anaerobic digestion and hydrogen from renewable energy systems. Using thermodynamic equilibrium analysis, kinetic reactor modeling and transient simulation, an integrated approach for the operation of a biogas-based Sabatier process was put forward, which was then verified using a lab scale heterogenous methanation reactor. The process simulation using a kinetic reactor model demonstrated the feasibility of the production of SNG at gas grid standards using a single reactor setup. The Wobbe index, CO2 content and calorific value were found to be controllable by the H2/CO2 ratio fed the methanation reactor. An optimal H2/CO2 ratio of 3.45-3.7 was seen to result in a product gas with high calorific value and Wobbe index. The dynamic reactor simulation verified that the process start-up was feasible within several minutes to facilitate surplus electricity use from renewable energy systems. PMID:25453430

  7. Sabatier Reactor System Integration with Microwave Plasma Methane Pyrolysis Post-Processor for Closed-Loop Hydrogen Recovery

    2010-01-01

    The Carbon Dioxide Reduction Assembly (CRA) designed and developed for the International Space Station (ISS) represents the state-of-the-art in carbon dioxide reduction (CDRe) technology. The CRA produces water and methane by reducing carbon dioxide with hydrogen via the Sabatier reaction. The water is recycled to the Oxygen Generation Assembly (OGA) and the methane is vented overboard resulting in a net loss of hydrogen. The proximity to earth and the relative ease of logistics resupply from earth allow for a semi-closed system on ISS. However, long-term manned space flight beyond low earth orbit (LEO) dictates a more thoroughly closed-loop system involving significantly higher recovery of hydrogen, and subsequent recovery of oxygen, to minimize costs associated with logistics resupply beyond LEO. The open-loop ISS system for CDRe can be made closed-loop for follow-on missions by further processing methane to recover hydrogen. For this purpose, a process technology has been developed that employs a microwave-generated plasma to reduce methane to hydrogen and acetylene resulting in 75% theoretical recovery of hydrogen. In 2009, a 1-man equivalent Plasma Pyrolysis Assembly (PPA) was delivered to the National Aeronautics and Space Administration (NASA) for technical evaluation. The PPA has been integrated with a Sabatier Development Unit (SDU). The integrated process configuration incorporates a sorbent bed to eliminate residual carbon dioxide and water vapor in the Sabatier methane product stream before it enters the PPA. This paper provides detailed information on the stand-alone and integrated performance of both the PPA and SDU. Additionally, the integrated test stand design and anticipated future work are discussed.

    1999-02-01

    In this article, former US Senator Paul Simon notes that, in his lifetime, the population of the world has tripled and is expected to quadruple. Among the effects of this population growth will be a 55% increase in nitrate emissions that will feed algae and compromise fish supplies. The US was extremely short-sighted when it reduced funding for the international family planning (FP) programs that benefit all nations. False accusations that the UN Population Fund (UNFPA) operates with a "bloated bureaucracy" ignore the fact that this agency has only 166 employees. More appropriate criticism would assert that the task the UNFPA is trying to accomplish is too important and too vast for such a small staff. Without FP programs, earth would now have to support an additional 400 million people. While contraceptive use by married women in developing countries has increased from 10% in 1965 to above 50% today and life expectancy is increasing, we must recognize the fact that we are currently unable to provide most of the world's population with safe water and sanitation and that increased population size will only exacerbate this problem. Encouraging voluntary FP is humanitarian and prudent and will help protect the entire population of the world. PMID:12294691

    The interaction of CO, CO2, CO + H2, CO2 + H2, and CO + CO2 + H2 with the nickel (110) single crystal termination has been investigated at 10(-1) mbar in situ as a function of the surface temperature in the 300-525 K range by means of infrared-visible sum frequency generation (IR-vis SFG) vibrational spectroscopy and by near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS). Several stable surface species have been observed and identified. Besides atomic carbon and precursors for graphenic C phases, five nonequivalent CO species have been distinguished, evidencing the role of coadsorption effects with H and C atoms, of H-induced activation of CO, and of surface reconstruction. At low temperature, carbonate species produced by the interaction of CO2 with atomic oxygen, which stems from the dissociation of CO2 into CO + O, are found on the surface. A metastable activated CO2(-) species is also detected, being at the same time a precursor state toward dissociation into CO and O in the reverse water-gas shift mechanism and a reactive species that undergoes direct conversion in the Sabatier methanation process. Finally, the stability of ethylidyne is deduced on the basis of our spectroscopic observations. PMID:26954458

    The National Library of Medicine has also just posted a Web site on Linus Pauling in its Profiles of Science series. While by no means as rich as the various Oregon State University sites, it is well worth visiting. There are texts of various speeches (including his Nobel address), many downloadable photographs, correspondence (including a poignant letter to James Watson and Francis Crick concerning their "rival" structures for DNA), and much else besides. There is a certain irony in Linus Pauling being honored by the National Library of Medicine. Ever since his 1949 presidential address to the American Chemical Society, and perhaps earlier, Pauling had been at loggerheads, sometimes acrimoniously so, with the medical establishment. It is easy to imagine him somewhere in the timeless infinitude of the empyrean sporting his characteristic ear-to-ear grin.

    Paul Barr, an extragalactic astronomer and spacecraft mission planner, died on 19 October 2005 at his home in Noordwijk, the Netherlands, at the age of 50. Although his scientific interests ranged from AGN to X-ray binaries, he will perhaps best be remembered for his mission planning skills on EXOSAT, ISO, and Integral. Many hundreds of observers have benefited from his ability to juggle seemingly impossible observing constraints and arrive at the optimum observing program. A rare talent. Barr was born in Sunderland, England, on 28 July 1995. After attending Saint Aidans Grammar School, where his father was the headmaster, he obtained his Bachelors Degree in astronomy from the University of London (June 1976) before moving to the Mullard Space Science Laboratory. There he obtained his Doctorate in X-ray astronomy in February 1980, using data from the Ariel V and Copernicus satellites. After a Post-Doctoral position at London University, where he did research into ultra-violet emission from AGN and X-ray binaries using IUE, Paul joined ESA in 1983. He worked on a wide range of missions including EXOSAT, ISO, and Integral. These observatories spanned the wavelength range from the Infra-red to the gamma-ray, giving insight into Paul's flexibility and ability to contribute in many areas. On ISO, Paul oversaw the scientific development and use of the very successful observation scheduling system — this topic became his specialty. As ISO operations became routine, he took up the challenge of space-borne gamma-ray astronomy and moved in 1997 to Integral where he worked in the Science Operation Centre (ISOC), at ESTEC in the Netherlands, as senior mission planner. He worked with the gamma-ray imager (IBIS) instrument team to ensure that operations of their instrument were properly supported by ESA and supported preparations of announcements of opportunity. In early 2005 the ISOC moved to Europe's Space Astronomy Centre (ESAC) just outside Madrid, Spain. Paul, however

Their exploration in NMR is intimately linked to the legacy of Paul Callaghan with his books Magnetic Resonance Microscopy and Translational Dynamics & Magnetic Resonance (Oxford University Press, Oxford 1991 and 2011) placing their focus with their titles on k and q, respectively. Some aspects of k and q have been revisited in the Paul Callaghan lecture of the author at the ISMAR Conference in Shanghai in 2015, which are reviewed here. In particular, there are two definitions of q, one relating to diffusive displacement (q) and the other to coherent flow (qv). Concerning the latter, it turns out, that in the short gradient pulse limit, the common anti-phase pulsed field-gradient scheme can be replaced with schemes employing three and more gradient pulses, which derive from differentiation rules in numerical analysis. Practical gradient modulation schemes with finite gradient pulse widths follow from these to measure velocity with improved accuracy. This approach can be expanded to acceleration and higher order transport coefficients with applications to measurements of flow and potentially also restricted diffusion.

  17. Paul Revere Osler: the other child

    PubMed Central

    2015-01-01

    Sir William Osler (1849–1919) is among the most honored and esteemed physicians of our time. His life, and that of his wife Grace Revere Osler (1854–1928), has been examined in great detail by historians and biographers and continues to be the subject of intensive scrutiny. Their son “Revere” (Edward Revere Osler) (1895–1917), who died in the Great War, is often mistakenly referred to as their only child. Grace had two previous pregnancies, having given birth to Paul Revere Osler, who lived but a week, early in their marriage in 1893 and to a stillborn infant during her first marriage to Dr. Samuel W. Gross in 1877. Information regarding these two events is often ill defined, cursory, or incorrect. New research provides further knowledge of these events and their impact, giving a fuller understanding and a more lucid historiography of the Oslers. PMID:25552789

  18. Charged nanodiamonds in a Paul trap

    NASA Astrophysics Data System (ADS)

    Streed, Erik

    2015-05-01

    Colloidal nanodiamonds were ionized with atmospheric electrospray and loaded into a Paul trap. Fluorescence from atom-like NV0 and NV- colour centres has been observed. The very low intrinsic absorption of bulk diamond is favourable for reducing the heating of cooled, trapped, nanodiamond ions from the surrounding blackbody radiation of the trapping apparatus. The isolated environment of the ion trap is also favourable for in-situ modification of nanodiamond to reduce absorption inducing defects through either physical or chemical processes. The presence or intentional introduction of high luminescence atom-like colour centre defects such as NV or SiV offer the prospect of direct laser cooling in nanodiamonds with low emissivity. Such laser cooled nano-ions are of interest for sympathetically cooling ions of similar charge/mass ratios that lack closed optical transitions, such as large biomolecules. ARC Future Fellow.

  19. Influence of Oxygenated Compounds on Reaction Products in a Microwave Plasma Methane Pyrolysis Assembly for Post-Processing of Sabatier Methane

    2012-01-01

    The state-of-the-art Carbon Dioxide Reduction Assembly (CRA) was delivered to the International Space Station (ISS) in April 2010. The system is designed to accept carbon dioxide from the Carbon Dioxide Removal Assembly and hydrogen from the Oxygen Generation Assembly. The two gases are reacted in the CRA in a Sabatier reactor to produce water and methane. Venting of methane results in an oxygen resupply requirement of about 378 lbs per crew member per year. If the oxygen is supplied as water, the total weight for resupply is about 476 lb per crew member per year. For long-term missions beyond low Earth orbit, during which resupply capabilities will be further limited, recovery of hydrogen from methane is highly desirable. For this purpose, NASA is pursuing development of a Plasma Pyrolysis Assembly (PPA) capable of recovering hydrogen from methane. Under certain conditions, water vapor and carbon dioxide (nominally intended to be separated from the CRA outlet stream) may be present in the PPA feed stream. Thus, testing was conducted in 2010 to determine the effect of these oxygenated compounds on PPA performance, particularly the effect of inlet carbon dioxide and water variations on the PPA product stream. This paper discusses the test set-up, analysis, and results of this testing.

  2. Paul Ehrenfest and the dilemmas of modernity.

    PubMed

    van Lunteren, Frans H; Hollestelle, Marijn J

    2013-09-01

    This essay considers the highly ambivalent attitude of the Austrian-Dutch physicist Paul Ehrenfest toward contemporary developments in both science and society. On the one hand, he was in the vanguard of the quantum and relativity revolutions, supported industrialization and economic planning based on mathematical models, and, in general, cherished technocratic ideals. The essay highlights several influences that shaped his attitude in these respects, from his ties with the Philips Physics Laboratory and his sojourns in the United States to the utopian visions of H. G. Wells. On the other hand, he was extremely worried about the harmful consequences of contemporary changes in science and society, such as specialization, the growing pace of city life, and the increasing dependence on modern technologies, be they material or mathematical. In this regard, he agreed with cultural critics such as Max Nordau, Henri Bergson, Ostwald Spengler, and Ludwig Klages. Rather than attempting to solve this paradox, the essay suggests that this kind of ambiguity characterized a great deal of innovative science in the period. PMID:24341262

  3. Paul Sollier, Pierre Janet, and their vicinity.

    2014-01-01

    Paul Sollier (1861-1933) and Pierre Janet (1859-1947) shared the same fate: achieving fame during their lives, then slipping into obscurity. However, their work is highly relevant for describing and explaining hysteria in the tradition of Jean-Martin Charcot (1825-1893). Both men had their teacher's clinical perspicacity, which enabled them to accumulate detailed clinical and psychological descriptions. These were published in books that achieved success in their day. From his descriptions, Sollier deduced a pathophysiology of hysteria in which a psychic inhibition led to a functional deficit in sensory-motor areas. This is partially confirmed by current functional brain imaging techniques. As for Janet, he developed concepts which are still valid today, involving personality dissociation, what he referred to as 'fixed ideas', and the subconscious. Sollier and Janet both saw hysteria as a response to the trigger of an emotional shock, specific to certain personalities. While the fundamental work by Joseph Babinski (1857-1932) on hysterical paralysis did much to enrich neurological semiology, Sollier contributed a novel description of the pathophysiology of hysteria, and Janet elucidated its psychopathological mechanisms.

  4. Paul Sollier: the first clinical neuropsychologist.

    PubMed

    Bogousslavsky, Julien; Walusinski, Olivier

    2011-01-01

    Paul Sollier (1861-1933) is perhaps the most unjustly forgotten follower of Jean-Martin Charcot. He studied with Désiré Bourneville, Charcot's second interne, and was considered by Léon Daudet as the cleverest collaborator of Charcot, along with Joseph Babinski. Charcot assigned him the task of summarizing the theories on memory, which led to two major books, in 1892 and 1900, that anticipated several contemporary concepts by several decades. In 1905-1906, the novelist Marcel Proust spent 6 weeks with Sollier in his sanatorium at Boulogne-Billancourt, and it is now obvious that several of Proust's ideas on involuntary memories which appear inside In Search of Lost Time (published 8 years later) had been inspired by Sollier's theories on the 'surge of reminiscences'. Sollier also designed the framework which led to the intellectual quotient (IQ) and made interesting studies on hysteria and behavioral issues in neurological diseases, activities that may make him the first modern clinical neuro psychologist. Sollier was also the first to correlate clinical findings with neurophysiological concepts, which makes him a precursor of our current approach to neurology and psychiatry. PMID:20938150

  5. The 'scientific artworks' of Doctor Paul Richer.

    PubMed

    Ruiz-Gómez, Natasha

    2013-06-01

    This article examines the little-known sculptures of pathology created by Doctor Paul Richer (1849-1933) in the 1890s for the so-called Musée Charcot at the Hôpital de la Salpêtrière in Paris. Under the direction of Doctor Jean-Martin Charcot (1825-1893), one of the founders of modern neurology, Richer was the head of the hospital's museum of pathological anatomy, as well as the Salpêtrière's resident artist. His 'series of figural representations of the principal types of nervous pathology' included busts of patients suffering from labio-glosso-laryngeal paralysis and myopathy, as well as sculptures depicting patients with Parkinson's disease and juvenile hypothyroidism. These patient portraits were seen as objective, while also paradoxically providing an alternative to mechanical media, such as the photograph and the cast, by permitting the doctor's intervention in not only controlling and animating the sitter, but also emphasising the patient's symptoms. This was a new kind of medical specimen: the 'scientific artwork', as they were called by a contemporary. This phrase, far from being an oxymoron, indicates the purposive collapse of the objective ('scientific') and subjective ('artistic') binary in Richer's sculptures of pathology. Through a detailed examination of three of Richer's works, this article problematises the categories traditionally used to describe, analyse and understand medical imagery and complicates our understanding of the relationship between science and art at the end of the nineteenth century.

    Buratti, Bonnie Jean; Veverka, Joseph

    2005-12-01

    Damon Paul Simonelli died unexpectedly on 1 December 2004 after he collapsed of heart failure at his home near Pasadena, California. Damon led pioneering studies in the scientific exploration of the satellites of the Solar System with spacecraft. He was a longtime member of the AAS's Division for Planetary Sciences community. Only two weeks before his death he attended the 2004 DPS meeting in Louisville where he presented a paper on the surface roughness of Phoebe based on Cassini observations. Damon was born in the Bronx, New York, on 15 August 1959. His father, Aldo Simonelli (d. 1990), was a clarinetist for the New York City Opera Company, and his mother, Alice Kennard Simonelli, was a secretary. His parents met while they were both students at the Julliard School. Family history has it that Damon's mother was an opera student, but she ruined her voice after singing when she had the flu. By junior high school, Damon had become a master at convincing his mother to wake him up at 3 AM to watch televised moonwalks, and to allow the entire family to view Star Trek episodes at the dinner table. Damon graduated from the Bronx High School of Science in 1976, with a composition on the New York State Regents exam that mentioned the significance of bicentennial toilet bowl lids. In addition to placing great emphasis on humor, the Simonelli family valued education. Damon's younger sister Danelle graduated from Vassar College and has served many years as a U. S. Park Ranger at Liberty Island. Damon graduated with a BA summa cum laude in physics from Cornell in 1980, where he had begun working with Carl Sagan. Damon had painstakingly gone through all the Viking images to look for any possibility of sentient life on Mars (he didn't find any). Perhaps the arrival of data from the first great explorers of the outer Solar System - Voyagers 1 and 2 - convinced Damon to continue at Cornell with Joe Veverka. While at Cornell, Damon began his pioneering work on the use of

  8. Linus Pauling's "molecular diseases": between history and memory.

    PubMed

    Strasser, Bruno J

    2002-08-30

    In 1949, Linus Pauling and his collaborators published a study in the journal Science entitled "Sickle Cell Anemia, a Molecular Disease." In this now classic study, they showed that hemoglobin from patients suffering from sickle cell anemia has a different electrical charge than hemoglobin from healthy individuals. This result demonstrated for the first time that an abnormal protein could be causally linked to a disease, and that genes determined the structure of proteins. This report made headline news and had a powerful impact on both the biomedical community and the general public. Fifty years later, this study is discussed in almost every medical and biological textbook and has became a favorite example in editorials to illustrate the progress of biomedical research. This article explores the history of Pauling's sickle cell anemia and its subsequent integration in different collective memories, up to the present day. It also discusses the function of the collective memories of Pauling's discovery for contemporary biomedical research. PMID:12400054

  9. Re-Os systematics of St. Paul's Rocks, equatorial Atlantic.

    NASA Astrophysics Data System (ADS)

    Blusztajn, J.; Hart, S. R.

    2006-12-01

    St. Paul's Rocks, small islets in the middle of the equatorial Atlantic (0°56'N, 29°22'W) just north of the St. Paul's Fracture zone, represent oceanic peridotites that are unique compared to abyssal peridotites. The main difference is the occurrence of modally metasomatized peridotites containing hornblende and pargasite. These mantle peridotites from St. Paul's Rocks show large Os isotopic heterogeneity, with present day 187Os/188Os ratios ranging from 0.1179 to 0.1273. In contrast, two hornblendite samples have very radiogenic Os isotopic compositions of 0.221 and 0.284. The Os concentrations vary from 0.003 ppb (hornblendite) to 5.8 ppb (spinel peridotite). Pargasite peridotites contain on average about 1.6 ppb Os. Even modally metasomatized samples with hornblende and pargasite have subchondritic Os isotopic ratios, indicating that enrichment processes did not disturb the Os isotopic system. The only indication of pervasive enrichment is a very high Re content in two of the amphibole peridotites (0.7 and 2.2 ppb). The unradiogenic Os isotopic ratios in the peridotites record ancient melting events with model ages of about 1.5 Ga. Three alkali basalts dredged on the flank of St. Paul's Rocks (1966 Atlantis II-20 cruise) have relatively high Os contents (62 to 167 ppt) and are quite radiogenic, with 187Os/188Os ranging from 0.167 to 0.239. Data from this study indicates that mixing of the different lithologies observed on St. Paul's Rocks cannot produce 187Os/188Os as high as that observed in the dredged basalts. On the other hand, the similar 187Os/188Os in the hornblendites and alkali basalts show that interaction between basalts and mantle peridotites took place. The very low Os isotopic ratios in St. Paul's Rocks, in conjunction with other Os studies from the equatorial Atlantic, indicate dispersed heterogeneities of old subcontinental lithospheric material in the oceanic mantle.

    Hoping to raise funds in 1975 for his namesake institute, Linus Pauling submitted to Esquire magazine a 32-page handwritten manuscript, "American Scientists and the Spirit of the Frontier." Angered when his submission for publication was declined, Pauling eventually gifted the original manuscript in 1986 to his friend, Linus Pauling Institute fundraiser Stephen Maddox, who would sell it in 2004 to the Wood Library-Museum of Anesthesiology. Published accurately here for the first time, the manuscript captures not only Pauling's sweeping metaphor of scientists as frontiersmen but also the creative process by which Pauling formulated his hydrate microcrystal theory of general anesthesia.

  19. Saint Paul Energy Park: the potential for district heating

    SciTech Connect

    Lee, C.; Kron, R.; Davis, H.

    1980-03-01

    The results of ANL's study of the energy and economic aspects of using district heating in the St. Paul Energy Park are summarized. The Energy Park is a 6 million ft/sup 2/ residential, commercial office, and light industrial complex to be built in the midway area of St. Paul, Minnesota. Space heating and cooling design loads for the park were calculated assuming that the ASHRAE's 90-75 energy-conserving construction standards would be used in constructing the park's buildings. Based in part on this assumption, ANL estimated the costs and energy use characteristics of six possible energy system options for supplying Energy Park's space heating, space cooling, and domestic hot water heating needs. The results indicate that in today's economy, a central heating and cooling plant with natural gas boilers and electrically driven centrifugal chillers with thermal storage has good potential for energy and economic savings and clearly merits further consideration.

  20. Paul trapping of charged particles in aqueous solution

    PubMed Central

    Guan, Weihua; Joseph, Sony; Park, Jae Hyun; Krstić, Predrag S.; Reed, Mark A.

    2011-01-01

    We experimentally demonstrate the feasibility of an aqueous Paul trap using a proof-of-principle planar device. Radio frequency voltages are used to generate an alternating focusing/defocusing potential well in two orthogonal directions. Individual charged particles are dynamically confined into nanometer scale in space. Compared with conventional Paul traps working in frictionless vacuum, the aqueous environment associated with damping forces and thermally induced fluctuations (Brownian noise) exerts a fundamental influence on the underlying physics. We investigate the impact of these two effects on the confining dynamics, with the aim to reduce the rms value of the positional fluctuations. We find that the rms fluctuations can be modulated by adjusting the voltages and frequencies. This technique provides an alternative for the localization and control of charged particles in an aqueous environment. PMID:21606331

    2016-06-01

    Trapping ions in Paul traps require high radio frequency voltages, which are generated using resonators. When operating traps in a cryogenic environment, an in-vacuum resonator showing low loss is crucial to limit the thermal load to the cryostat. In this study, we present a guide for the design and production of compact, shielded cryogenic resonators. We produced and characterized three different types of resonators and furthermore demonstrate efficient impedance matching of these resonators at cryogenic temperatures.

This computer-controlled Pockels cell polarimeter has been restored to working order and offers a wide range of possibilities: almost all functions are under remote control, linear or circular polarization observations are both possible, a filter slide provides easy access to up to six different bandpasses, and the Pockels cell and Fabry lenses are kept at a constant temperature. In addition to controlling the instrument, the software allows the use of pre-defined sequences of observation, and does data acquisition and reduction. (SECTION: Astronomical Instrumentation)

    Farley, Donald T.

    2011-03-01

    Paul M. Kintner Jr., who died on 16 November 2010 of pancreatic cancer, was a pioneer in studies of Earth's space environment and of space weather. His discoveries about plasma waves, wave-particle interactions, nonlinear structures, irregularities, and radio wave propagation in random media revealed how heavy ions are injected into the magnetosphere and characterized the sometimes catastrophic effects of scintillations produced in the ionosphere on satellite navigation systems (e.g., the Global Positioning System (GPS)). Paul, a professor of electrical and computer engineering at Cornell University, pioneered the use of multiple-sensor electric field and plasma wave measurements on sounding rockets and satellites and used these sensors (together the multiple sensors are sometimes called a plasma wave interferometer) to characterize plasma waves by their wavelengths and wave vectors and to identify new solitary structures in space plasmas and describe their speed, shape, and size. This interferometer was particularly useful in investigating transverse ion acceleration in the polar ionosphere. In a decisive sounding rocket experiment, Sounding of the Cleft Ion Fountain Energization Region (SCIFER), in 1995 at 1400 kilometers over Svalbard, Norway, Paul showed that the principal source of this acceleration (the source of mass in the magnetosphere) is short-wavelength broadband waves whose frequencies are determined primarily by Doppler broadening. He is also credited with discovering lower hybrid solitary structures and describing them as rotating modes in magnetic field-aligned density cavities that produce transverse ion acceleration. He extended the approach to higher frequencies and was the first to measure the speed and shape of electron solitary holes (Bernstein-Greene-Kruskal (BGK) modes).

  10. Paul Drude's Prediction of Nonreciprocal Mutual Inductance for Tesla Transformers

    PubMed Central

    McGuyer, Bart

    2014-01-01

    Inductors, transmission lines, and Tesla transformers have been modeled with lumped-element equivalent circuits for over a century. In a well-known paper from 1904, Paul Drude predicts that the mutual inductance for an unloaded Tesla transformer should be nonreciprocal. This historical curiosity is mostly forgotten today, perhaps because it appears incorrect. However, Drude's prediction is shown to be correct for the conditions treated, demonstrating the importance of constraints in deriving equivalent circuits for distributed systems. The predicted nonreciprocity is not fundamental, but instead is an artifact of the misrepresentation of energy by an equivalent circuit. The application to modern equivalent circuits is discussed.

In the case of the later editions, I discuss Dirac’s negative attitude toward renormalized quantum electrodynamics.

    During his distinguished 37-year career as a research physicist at the Honeywell Research Center in Minneapolis, Minnesota, Dr. Paul W. Kruse (1927-2012) played leadership roles in two disruptive infrared detector technologies, the narrow-gap semiconductor alloy HgCdTe and the silicon CMOS-based microbolometer array, both of which revolutionized the worldwide infrared detector industry. He served on numerous government advisory boards and panels, including the Army Scientific Advisory Panel and the Army Science Board, for which he received the Outstanding Civilian Service Medal. After retiring for Honeywell in 1993, he remained active in the infrared detector field in several roles: as a successful small-business entrepreneur, as an author of two books, and as a SPIE lecturer. His books, papers and lectures have educated new generations of workers in the infrared detector industry. His career, a model for industrial research physicists, has had major and permanent impacts on the worldwide infrared detector industry. This paper is a summary of the career of Paul W. Kruse, as well as a tribute to that career and its lasting legacy.

  15. Perimeter ring currents in benzenoids from Pauling bond orders.

    PubMed

    Fowler, Patrick W; Myrvold, Wendy; Jenkinson, Daniel; Bird, William H

    2016-04-28

    It is shown that the ring currents in perimeter hexagonal rings of Kekulean benzenoids, as estimated within the Randić conjugated-circuit model, can be calculated directly without tedious pairwise comparison of Kekulé structures or Kekulé counting for cycle-deleted subgraphs. Required are only the Pauling bond orders of perimeter bonds and the number of Kekulé structures of the benzenoid, both readily available from the adjacency matrix of the carbon skeleton. This approach provides easy calculation of complete current maps for benzenoids in which every face has at least one bond on the perimeter (as in the example of cata-condensed benzenoids), and allows qualitative evaluation of the main ring-current contributions to (1)H chemical shifts in general benzenoids. A combined Randić-Pauling model for correlation of ring current and bond length through bond order is derived and shown to be consistent with resilience of current under bond alternation.

  16. Acoustic Coupling Effects in ST Paul's Cathedral, London

    NASA Astrophysics Data System (ADS)

    ANDERSON, J. S.; BRATOS-ANDERSON, M.

    2000-09-01

    In St Paul's Cathedral there are many arches, columns and cornices which enable the internal space to be divided into subspaces. The subspaces may be considered to be acoustically coupled via areas which connect the rooms. Two of the most acoustically important subspaces in the Cathedral are the choir and the space under the dome. The choir, the space within the wooden choir stalls, has more sound absorption than the rest of the building, which is mostly marble and Portland stone. In the model of coupled subspaces an acoustic energy balance equation, applied to a diffuse field, is derived for each subspace. In St Paul's Cathedral the internal space is divided into 70 acoustical subspaces. The initial-value problem which is formulated by the system of 70 acoustic energy balance equations with initial conditions has been reduced to the eigenvalue problem. The decay of sound energy density has been obtained for different locations in the Cathedral and for different positions of the sound source. Experimentally obtained sound decay curves are in good agreement with numerical results. Both the experimental and numerical results demonstrate the fine structure of reverberation.

  3. Historical antecedents to the philosophy of Paul Feyerabend.

    PubMed

    Munévar, Gonzalo

    2016-06-01

    Paul Feyerabend has been considered a very radical philosopher of science for proposing that we may advance hypotheses contrary to well-confirmed experimental results, that observations make theoretical assumptions, that all methodological rules have exceptions, that ordinary citizens may challenge the judgment of experts, and that human happiness should be a key value for science. As radical as these theses may sound, they all have historical antecedents. In defending the Copernican view, Galileo exemplified the first two; Mill, Aristotle and Machiavelli all argued for pluralism; Aristotle gave commonsense reasons for why ordinary citizens may be able to judge the work of experts; and a combination of Plato's and Aristotle's views can offer strong support for the connection between science and happiness.

    2004-04-01

    In 2002 physicists around the world celebrated the centenary of the birth of Paul Dirac, OM, FRS, Nobel Laureate, who was one of the greatest physicists of the 20th century. He made towering contributions to the formulation of quantum mechanics and he was one of the principal creators of quantum field theory. In 1928 he combined relativity and quantum mechanics in the Dirac equation, which provides a natural description for the spin of the electron and which led to the prediction, by Dirac himself, of the existence of anti-matter. In this article I try to explain, in the simplest terms, these major contributions to physics and to give some flavour of the man himself.

    I summarize certain aspects of Paul Feyerabend's account of the development of Western rationalism, show the ways in which that account is supposed to run up against an alternative, that of Karl Popper, and then try to give a preliminary comparison of the two. My interest is primarily in whether what Feyerabend called his 'story' constitutes a possible history of our epistemic concepts and their trajectory. I express some grave reservations about that story, and about Feyerabend's framework, finding Popper's views less problematic here. However, I also suggest that one important aspect of Feyerabend's material, his treatment of religious belief, can be given an interpretation which makes it tenable, and perhaps preferable to a Popperian approach.

  6. Baring the soul: Paul Bindrim, Abraham Maslow and 'nude psychotherapy'.

    PubMed

    Nicholson, Ian

    2007-01-01

    Nude psychotherapy is one of the most flamboyant therapeutic techniques ever developed in American psychology. Largely forgotten today, the therapy was an academic and popular sensation upon its introduction in 1967. Developed by psychologist Paul Bindrim, the therapy promised to guide clients to their authentic selves through the systematic removal of clothing. This paper explores the intellectual, cultural and ethical context of nude therapy and its significance as a form of unchurched spirituality. Although nude therapy has an indisputable tabloid character, it is also rooted in a long-standing academic search for authenticity and ultimate meaning through science. Bindrim's career demonstrates the historically long-standing interweaving of spirituality and science within American psychology while simultaneously highlighting the field's extraordinary capacity for adaptive reinvention.

    Pressure, together with temperature and magnetic field, is an important thermodynamical parameter in physics. Investigating the response of a compound or of a material to pressure allows to elucidate ground states, investigate their interplay and interactions and determine microscopic parameters. Pressure tuning is used to establish phase diagrams, study phase transitions and identify critical points. Muon spin rotation/relaxation (μSR) is now a standard technique making increasing significant contribution in condensed matter physics, material science research and other fields. In this review, we will discuss specific requirements and challenges to perform μSR experiments under pressure, introduce the high pressure muon facility at the Paul Scherrer Institute (PSI, Switzerland) and present selected results obtained by combining the sensitivity of the μSR technique with pressure.

  8. Transcultural nursing: a perspective derived from Jean-Paul Sartre.

    Rajan, M F

    1995-09-01

    Transcultural nursing care is a well-established theoretical framework. This theory, developed by Madeleine Leininger, can have an impact on clinical practice, academic preparation and nursing research. The heightened interest in applying transcultural care and the increased need to espouse this framework have been triggered by constant population changes. This paper defines transcultural nursing care and expands its definition further by comparing and contrasting it with Jean-Paul Sartre's existentialist perspective. The two modes of existence as defined by Sartre are closely examined. Concrete examples are offered as cultural phenomena and the components of a cultural assessment are discussed and applied. The philosophical thesis is approached from a transcultural nursing perspective and existentialism is shown to serve as a foundation for transcultural nursing. The advantages and disadvantages of transcultural nursing practice and the preparation of transcultural nurses are finally addressed. PMID:7499611

  10. One More Legacy of Paul F. Brandwein: Creating Scientists

    2011-06-01

    This paper studies the influence of Paul F. Brandwein, author, scientist, teacher and mentor, publisher, humanist, and environmentalist, on gifted youngsters who later became scientists, based primarily on information gathered from surveys completed by 25 of his students and one colleague. It also traces his profound interactions with science educators. It illuminates the theories of Brandwein and his protégés and colleagues about the interaction of environment, schooling, and education and Brandwein's belief in having students do original research (that is, research whose results are unknown) on their way to discovering their future scientific paths. It tests Brandwein's 1955 hypothesis on the characteristics typical of the young who eventually become scientists, namely: Three factors are considered as being significant in the development of future scientists: a Genetic Factor with a primary base in heredity (general intelligence, numerical ability, and verbal ability); a Predisposing Factor, with a primary base in functions which are psychological in nature; an Activating Factor, with a primary base in the opportunities offered in school and in the special skills of the teacher. High intelligence alone does not make a youngster a scientist (p xix).

    Physician, scientist and revolutionary are the biographical aspects that had better summarize the life of Jean-Paul Marat (1743-1793). Due to the role that he played during the French Revolution, his work as a physician and scientist, prior to the events of l789, was forgotten. Marat made important contributions in the area of optics and electricity reflected in numerous publications, as well as translating Newton's Opticks (1787). Well known for his radical and aggressive ideas, his political vocation led him to embrace the revolutionary cause after the events of the Bastille. His figure was not indifferent to his contemporaries; although considered a hero by the poorest citizens, aristocrats and bourgeois considered him a cruel extremist. During the last years of his life, he suffered a cutaneous disease, the diagnosis of which is still a matter of controversy. Proposed diagnoses include eczema, seborrheic dermatitis, scabies and dermatitis herpetica, among others. Marat was assassinated by Charlotte Corday in 1793, becoming a martyr for some segments of the society that worshiped his memory. He was a man with a complex and curious personality whose figure and legacy are still a matter of discussion. PMID:20361162

    PubMed

    Chernin, E

    1988-01-01

    Paul de Kruif's book, Microbe Hunters, published in New York in 1926, was a romanticized medical "history," written in a breathless style, that describes the lives and works of a dozen famous figures, ranging from Leeuwenhoek to Sir Ronald Ross. Ross, who received the Nobel Prize in 1902 for his discovery that certain mosquitoes transmit malaria, resented de Kruif's personal remarks and his version of the malaria story, especially concerning the disputes with Italian workers over priorities. In a little-known polemic "review" of Microbe Hunters, Ross castigated de Kruif for statements he considered libelous. While Ross could not sue for libel across the Atlantic, his threatened action for libel forced the publisher of the British edition of Microbe Hunters to delete the chapter about Ross and one about David Bruce, Ross's countryman. de Kruif's book, a best-seller in its day and influential among the young for a generation, now seems gauche and anachronistic. While Ross seems to have been justified in some of his complaints about Microbe Hunters, the bitter tone of his reactions all but confirms de Kruif's opinion of him. Ross died in 1932 with a permanent niche in medical history; de Kruif died in 1971 and is little remembered except, perhaps, for Microbe Hunters. PMID:3293166

    Astronaut Paul W. Richards, STS-102 mission specialist, works in the cargo bay of the Space Shuttle Discovery during the second of two scheduled space walks. Richards, along with astronaut Andy Thomas, spent 6.5 hours outside the International Space Station (ISS), continuing work to outfit the station and prepare for delivery of its robotic arm. STS-102 delivered the first Multipurpose Logistics Modules (MPLM) named Leonardo, which was filled with equipment and supplies to outfit the U.S. Destiny Laboratory Module. The Leonardo MPLM is the first of three such pressurized modules that will serve as the ISS' moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall mission and the 8th Space Station Assembly Flight, STS-102 mission also served as a crew rotation flight. It delivered the Expedition Two crew to the Station and returned the Expedition One crew back to Earth.

    Educational components are encouraged, sometimes required, in grant-funded research. However, it is not reasonable to expect scientists to master a second field, education. The NASA Office of Space Science has included regional Broker/Facilitator centers in its ``ecosystem" (multidimensional education/outreach network) to help bridge the gap. Broker/Facilitators are to ``work with the space science community to identify high-leverage opportunities for education/outreach and help arrange collaborations between scientists and educators" (www.hq.nas.gov/office/oss/education/edprog.html). The regional center at DePaul University serves six states (IA, IL, IN, MN, MO, and WI). Full activity will begin in August 1998, when staff are in place. Initially, we expect to assist scientists who wish to develop educational plans to complement their research programs, and help find educational partners for research groups or individuals. Further services, activities, and programs are being planned; feedback from researchers and others is being sought. Progress and further details of plans will be presented.

    The professional career of Paul Nitsche reflects the contradictory path taken by a German institutional psychiatrist who was a leader in the field at the time. During the Weimar Republic he advocated improving the institutional system based on principles of psychiatric reform, but was already receptive to concepts of racial hygiene. Shortly after the National Socialists seized power, Nitsche was already an influential proponent and participant in eugenic measures in Saxony and actively involved in implementing the "Law for the Prevention of Genetically Diseased Offspring." He increasingly appraised the value of a patient according to the person's economic performance. It was also Nitsche's opinion that the consequence of this extreme rationalization of human life was to exterminate "life unworthy of life." As a T4 appointed head assessor he decided in the last instance whether thousands of people would live or die. As the Medical Director of the T4 program, he was later directly responsible for continuing the massacre as "decentralized euthanasia." At the euthanasia trial in Dresden he was condemned to death and executed in 1948. PMID:22399059

    A power law regression equation, = 1.46(<ρ(rc)>/r)-0.19, connecting the average experimental bond lengths, , with the average accumulation of the electron density at the bond critical point, <ρ(rc)>, between bonded metal M and oxygen atoms, determined at ambient conditions for oxide crystals, where r is the row number of the M atom, is similar to the regression equation R(M-O) = 1.39(ρ(rc)/r)-0.21 determined for three perovskite crystals for pressures as high as 80 GPa. The two equations are also comparable with those, = 1.43(/r)-0.21, determined for a large number of oxide crystals at ambient conditions and = 1.39(/r)-0.22, determined for geometry optimized hydroxyacid molecules, that connect the bond lengths to the average Pauling electrostatic bond strength, , for the M-O bonded interactions. On the basis of the correspondence between the two sets of equations connecting ρ(rc) and the Pauling bond strength s with bond length, it appears that Pauling’s simple definition of bond strength closely mimics the accumulation of the electron density between bonded pairs of atoms. The similarity of the expressions for the crystals and molecules is compelling evidence that the M-O bonded interactions for the crystals and molecules 2 containing the same bonded interactions are comparable. Similar expressions, connecting bond lengths and bond strength, have also been found to hold for fluoride, nitride and sulfide molecules and crystals. The Brown-Shannon bond valence, σ, power law expression σ = [R1/(R(M-O)]N that has found wide use in crystal chemistry, is shown to be connected to a more universal expression determined for oxides and the perovskites, <ρ(rc)> = r[(1.41)/]4.76, demonstrating that the bond valence for a bonded interaction is likewise closely connected to the accumulation of the electron density between the bonded atoms. Unlike the Brown-Shannon expression, it is universal in that it holds for the M

    Paul Greengard was born in New York City in 1925. After completing high school, he served three years in the US Navy during World War II and then completed his bachelor's degree at Hamilton College where he majored in physics and mathematics. He obtained a PhD in biophysics from Johns Hopkins University in 1953 and pursued postdoctoral training with Wilhelm Feldberg at the National Institute for Medical Research in England. After eight years as head of biochemistry at Geigy, and sabbaticals at Albert Einstein College of Medicine and Vanderbilt University, he joined the Yale University faculty as a full professor of pharmacology in 1968. While he was at Yale, Greengard's laboratory performed groundbreaking research, which demonstrated a role for cyclic nucleotides, protein kinases and protein phosphatases, and their protein substrates in the regulation of synaptic transmission. In 1983, Greengard moved to The Rockefeller University, where he has since served as the Vincent Astor Professor and Head of the Laboratory of Molecular and Cellular Neuroscience. Greengard's paradigm-shifting research has continued at Rockefeller and has informed our understanding and possible treatment of a host of brain disorders, including schizophrenia, Alzheimer's disease, Parkinson's disease, and depression. He is the author of more than 950 research articles and reviews. Greengard has received numerous awards and honors, including the Nobel Prize in Physiology or Medicine in 2000, the Metropolitan Life Foundation Award for Medical Research, The National Academy of Sciences Award in Neuroscience, the Ralph W. Gerard Prize in Neuroscience for the Society for Neuroscience, and the Karolinska Institutet's Bicentennial Gold Medal. He is a member of the US National Academy of Sciences and the Institute of Medicine of the National Academies. The following interview was conducted on May 29, 2012. PMID:23294305

    1995-01-01

    In a 16-page letter which is widely viewed by women's groups as an effort to win support for the Vatican's position at the upcoming UN Conference on Women in Beijing, Pope John Paul II apologizes to women throughout the world for the church's historic complicity in their oppression. Although phrased in general terms, the letter contains language and ideas of a far more feminist tone than any previous statements or declarations made by the Pontiff. Calling for increased respect for women and sensitivity to their needs, the letter also claims that "there is an urgent need to achieve real equality in every area: equal pay for equal work, protection for working mothers, fairness in career advancements, equality of spouses with regard to family rights and recognition of everything that is part of the rights and duties of citizens in a democratic state." Recognizing women's significant achievements and sacrifices inside and outside of the home, the Pope expressed admiration for "those women of good will who have devoted their lives to defending the dignity of womanhood by fighting for their basic social, economic and political rights, demonstrating courageous initiative at a time when this was considered extremely inappropriate, the sign of a lack of femininity, a manifestation of exhibitionism, and even a sin." Although the letter heralds a new awareness in the Vatican of women's views, concerns and grievances, the Pope has not signaled any dramatic changes in official church policy: women's ordination, divorce, abortion and birth control are still considered beyond the pale of acceptability.

  2. Specificity in Transition State Binding: The Pauling Model Revisited

    PubMed Central

    Amyes, Tina L.; Richard, John P.

    2013-01-01

    Linus Pauling proposed that the large rate accelerations for enzymes are due to the high specificity of the protein catalyst for binding the reaction transition state. The observation that stable analogs of the transition states for enzymatic reactions often act as tight-binding binding inhibitors provided early support for this simple and elegant proposal. We review experimental results which support the proposal that Pauling’s model provides a satisfactory explanation for the rate accelerations for many heterolytic enzymatic reactions through high energy reaction intermediates, such as proton transfer and decarboxylation. Specificity in transition state binding is obtained when the total intrinsic binding energy of the substrate is significantly larger than the binding energy observed at the Michaelis complex. The results of recent studies to characterize the specificity in binding of the enolate oxygen at the transition state for the 1,3-isomerization reaction catalyzed by ketosteroid isomerase are reviewed. Interactions between pig heart succinyl-CoA:3-oxoacid coenzyme A transferase (SCOT) and the nonreacting portions of CoA are responsible for a rate increase of 3 × 1012-fold, which is close to the estimated total 5 × 1013-fold enzymatic rate acceleration. Studies that partition the interactions between SCOT and CoA into their contributing parts are reviewed. Interactions of the protein with the substrate phosphodianion group provide a ca. 12 kcal/mol stabilization of the transition state for the reactions catalyzed by triosephosphate isomerase, orotidine 5′-monophosphate decarboxylase and α-glycerol phosphate dehydrogenase. The interactions of these enzymes with the substrate piece phosphite dianion provide a 6 – 8 kcal/mol stabilization of the transition state for reaction of the appropriate truncated substrate. Enzyme activation by phosphite dianion reflects the higher dianion affinity for binding to the enzyme-transition state complex compared

    In May 1918 Paul Ehrenfest received a monograph from Niels Bohr in which Bohr had used Ehrenfest's adiabatic principle as an essential assumption for understanding atomic structure. Ehrenfest responded by inviting Bohr, whom he had never met, to give a talk at a meeting in Leiden in late April 1919, which Bohr accepted; he lived with Ehrenfest, his mathematician wife Tatyana, and their young family for two weeks. Albert Einstein was unable to attend this meeting, but in October 1919 he visited his old friend Ehrenfest and his family in Leiden, where Ehrenfest told him how much he had enjoyed and profited from Bohr's visit. Einstein first met Bohr when Bohr gave a lecture in Berlin at the end of April 1920, and the two immediately proclaimed unbounded admiration for each other as physicists and as human beings. Ehrenfest hoped that he and they would meet at the Third Solvay Conference in Brussels in early April 1921, but his hope was unfulfilled. Einstein, the only physicist from Germany who was invited to it in this bitter postwar atmosphere, decided instead to accompany Chaim Weizmann on a trip to the United States to help raise money for the new Hebrew University in Jerusalem. Bohr became so overworked with the planning and construction of his new Institute for Theoretical Physics in Copenhagen that he could only draft the first part of his Solvay report and ask Ehrenfest to present it, which Ehrenfest agreed to do following the presentation of his own report. After recovering his strength, Bohr invited Ehrenfest to give a lecture in Copenhagen that fall, and Ehrenfest, battling his deep-seated self-doubts, spent three weeks in Copenhagen in December 1921 accompanied by his daughter Tanya and her future husband, the two Ehrenfests staying with the Bohrs in their apartment in Bohr's new Institute for Theoretical Physics. Immediately after leaving Copenhagen, Ehrenfest wrote to Einstein, telling him once again that Bohr was a prodigious physicist, and again

    In November 1949, chemist Linus Pauling and three colleagues published an article on sickle-cell anemia, a study that opened up new and exciting possibilities for research into such 'molecular diseases'. Even before this celebrated publication appeared in Science, Pauling foresaw its potential benefits and announced it as a medical breakthrough: '... our structural chemistry and understanding of molecules is getting to the point where it should be of assistance in converting medicine into a real science' [Guiles, R. (1949) Discovery of blood disease called key to cancer research. The Detroit Times 13 Sep 1949, Newspaper Clippings 1949n.18, Pauling Papers.]. Their discovery--that this debilitating disorder was caused by an abnormal form of hemoglobin--was borne out of a rich mix of expertise, from Pauling's remarkable intuition to the careful experimental chemistry of his student Harvey A. Itano. It also relied upon technological innovation: a custom-made electrophoresis machine housed at the California Institute of Technology was the perfect tool to reveal fundamental chemical differences between normal and abnormal forms of hemoglobin. Not only did this work establish a new way of looking at inherited diseases, it also stimulated the mass production of the electrophoresis machine as an essential investigative and diagnostic tool. A close inspection of this case study illustrates just how Pauling ran his laboratory and helps to explain how one man could achieve so much over his lifetime. PMID:17602747

    2006-03-01

    At the start of the 1930s, theoretician Paul Ehrenfest spent much of his time traveling through America and Europe while engaged in a steady stream of lectures. This traveling phase coincided with a frantic and intense period of negative self-examination, financial difficulty, and various other personal concerns that would ultimately lead to his 1933 suicide. Throughout these final years, he kept up a steady correspondence with his brother Hugo, a physician based in Saint Louis. Ten years older than Paul, Hugo freely doled out frank psychological advice about subjects ranging from the proper treatment of children to the dangers of self-pity. Through a look at some of the letters exchanged between the two brothers, this talk will examine the role Hugo played during the dark final years of Paul Ehrenfest's life.

    Translational research and precision medicine are based on a profound knowledge of cellular and molecular mechanisms contributing to various physiologic processes and pathologic reactions in diverse organs. Whereas specific molecular interactions and mechanisms have been identified during the past 5 decades, the underlying principles were defined much earlier and originate from to the seminal observations made by outstanding researchers between 1850 and 1915. One of the most outstanding exponents of these scientists is Paul Ehrlich. His work resulted not only in the foundation and birth of modern hematology and immunology, but also led to the development of chemotherapy and specific targeted treatment concepts. In 2015, the Medical University of Vienna organized a memorial meeting, with the aim of honoring Paul Ehrlich's contributions to science, and to commemorate the 100th anniversary of his death. The authors of the current review served as faculty members and dedicate this paper to Paul Ehrlich and his remarkable contributions to medicine. PMID:26845587

    In The Logic of Life (1970), Francois Jacob (1920- ), Nobel Prize laureate in Physiology or Medicine (1965), proclaimed the end of vitalism based on the concept of life. More than two decades before this capital sentence condemning vitalism was pronounced, Georges Canguilhem (1904-1995), a French philosopher of medicine, already acknowledged that eighteenth-century vitalism was scientifically retrograde and politically reactionary or counter-revolutionary insofar as it was rooted in the animism of Georg Ernst Stahl (1660-1734). The negative preconception of the term 'vitalism' came to be established as an orthodox view, since Claude Bernard (1813-1878) unfairly criticized contemporary vitalism in order to propagate his idea of experimental medicine. An eminent evolutionary biologist like Ernst Mayr (1904-2005) still defended similar views in This is Biology (1997), arguing that if vitalists were decisive and convincing in their rejection of the Cartesian model (negative heuristics), however they were equally indecisive and unconvincing in their own explanatory endeavors (positive heuristics). Historically speaking, vitalists came to the forefront for their outstanding criticism of Cartesian mechanism and physicochemical reductionism, while their innovative concepts and theories were underestimated and received much less attention. Is it true that vitalism was merely a pseudo-science, representing a kind of romanticism or mysticism in biomedical science? Did vitalists lack any positive heuristics in their biomedical research? Above all, what was actually the so.called 'vitalism'? This paper aims to reveal the positive heuristics of vitalism defined by Paul.Joseph Barthez (1734-1806) who was the founder of the vitalist school of Montpellier. To this end, his work and idea are introduced with regard to the vying doctrines in physiology and medicine. At the moment when he taught at the medical school of Montpellier, his colleagues advocated the mechanism of Rene

    This article reports on the disease that afflicted Paul Klee, the famous artist. He died before the disease that killed him could be properly diagnosed. There was some conjecture afterwards that he may have suffered from scleroderma. The thorough and diligent research the author of this article has carried out over many years allows him to argue that Paul Klee was suffering from this autoimmune disease since 1935. With a degree of probability that borders on certainty, it seems that the artist suffered from ‘diffuse systemic sclerosis’, and it is from this, the most severe form of the rare autoimmune disease, that he died in 1940.

  9. Volcano hazards and potential risks on St. Paul Island, Pribilof Islands, Bering Sea, Alaska

    2009-05-01

    Volcano hazards and potential risks on St. Paul Island, Alaska, are assessed on the basis of the recent volcanic history of the island. The long-term frequency of volcanic eruptions is estimated using a count of 40 identifiable vents considered to represent separate eruptions. Assuming regular temporal spacing of these events during the period 360,000 to 3230 y.b.p., the estimated mean recurrence time is 0.11 × 10 - 3 eruption/year and the eruptive interval is approximately 8900 years. Volcano hazards on St. Paul are associated exclusively with the eruption of low viscosity alkali basaltic magma. The most important are lava flows, tephra fallout, and base surges. Other hazards include volcanic gases, seismicity and ground deformation associated with dike intrusion beneath rift zones, and explosive lava-water interactions along coastal regions and water-saturated ground. The general characteristics of past volcanism on St. Paul indicate that the most likely styles of future eruptions will be (1) Hawaiian-style eruptions with fire fountains and pahoehoe lava flows issuing from one of two polygenetic shield volcanoes on the island; (2) Strombolian-style, scoria cone-building eruptions with associated tephra fallout and eruption of short pahoehoe lava flows; and (3) explosive Surtseyan-style, phreatomagmatic eruptions initiating at some point along St. Paul's insular shelf. Given the relatively restricted range in volcanic phenomena on St. Paul, the most significant question regarding volcano hazard and risk assessment is whether future eruptions will be confined to the same region on the island as the most recent activity. If future activity follows the recent past, resulting volcano hazards will most likely be located at inland areas sufficiently far from habitation that they will pose little threat to life or property. An important caveat, however, is that St. Paul is constructed almost entirely from the products of volcanic eruptions with vents located all over

  16. Headache classification and the Bible: Was St Paul's thorn in the flesh migraine?

    PubMed

    Göbel, H; Isler, H; Hasenfratz, H P

    1995-06-01

    The conversion of Saul to Paul was a major event in the history of Western culture. Compared with its impact, any medical comments may seem redundant, but they have kept their place in the literature for many centuries. The flashing light that caused Saul to fall is often explained as solar retinopathy or keratitis, a seizure, or even a hysterical fit. These interpretations propose either a trivial injury or disease that would interfere with mental health. Neither version is quite compatible with the dramatic dimension of the event and with Paul's later achievements and sufferings. In later years, Paul became a great manager, preacher and writer who was able to carry on under any kind of duress, though not without very painful reactions. He was suffering from bouts of unilateral headache, and also from a chronic eye condition which gave great trouble to his followers but did not cause lasting damage; the descriptions fulfil the criteria for migraine without aura of the 1988 Headache Classification. If the flashing light that caused Paul to fall down is interpreted as a visual migraine aura, with the additional symptoms of "not seeing" or photophobia and anorexia, it falls into place with his later history of migraine.

    2016-01-01

    Relict woolly mammoth (Mammuthus primigenius) populations survived on several small Beringian islands for thousands of years after mainland populations went extinct. Here we present multiproxy paleoenvironmental records to investigate the timing, causes, and consequences of mammoth disappearance from St. Paul Island, Alaska. Five independent indicators of extinction show that mammoths survived on St. Paul until 5,600 ± 100 y ago. Vegetation composition remained stable during the extinction window, and there is no evidence of human presence on the island before 1787 CE, suggesting that these factors were not extinction drivers. Instead, the extinction coincided with declining freshwater resources and drier climates between 7,850 and 5,600 y ago, as inferred from sedimentary magnetic susceptibility, oxygen isotopes, and diatom and cladoceran assemblages in a sediment core from a freshwater lake on the island, and stable nitrogen isotopes from mammoth remains. Contrary to other extinction models for the St. Paul mammoth population, this evidence indicates that this mammoth population died out because of the synergistic effects of shrinking island area and freshwater scarcity caused by rising sea levels and regional climate change. Degradation of water quality by intensified mammoth activity around the lake likely exacerbated the situation. The St. Paul mammoth demise is now one of the best-dated prehistoric extinctions, highlighting freshwater limitation as an overlooked extinction driver and underscoring the vulnerability of small island populations to environmental change, even in the absence of human influence.

    PubMed

    Sapisochin, Gabriel

    2016-06-01

    In this commentary on Paul Denis's paper 'The drive revisited: mastery and satisfaction', the author defends the idea of a plurality of metapsychologies that must be contrasted with and distinguished from each other while avoiding incompatible translations between models. In this connection he presents various theoretical approaches to aggression and the death drive, and demonstrates the differences between the drive model and the model underlying the theory of internalized object relations. The author holds that the concept of the internal object differs from Freud's notion of the representation (Vorstellung). He also considers that the imago as defined by Paul Denis in fact corresponds to the concept of the internal object. Lastly, he addresses the complex issue of listening to archaic forms of psychic functioning and their non-discursive presentation within the analytic process, which affects the transference-countertransference link.

  15. Dipole Field Effects on Ion Ejections from a Paul Ion Trap

    NASA Technical Reports Server (NTRS)

    MacAskill, J. A.; Chutjian, A.

    2011-01-01

    Attempts at improving the quality of mass spectra obtained from a Paul trap mass spectrometer prompted an investigation of the effects of additional fields to supplement the primary rf quadrupole trapping field. Reported here are the results of the first in a series of tests that focuses on the application of a single dipole field to augment the trapping and subsequent ejections of ions stored within a Paul trap. Measurements are presented for a fixed quadrupole frequency with varying dipole frequencies. The presence of the dipole field during the quadrupole trapping phase causes ion ejections of single m/z species at discrete dipole frequencies. During the mass analysis phase, the varying dipole frequency produces a complex set of resonant structures that impact ejection time (mass range), as well as mass spectral peak intensity and width

  16. Buffer gas loading and Doppler cooling of strontium ions in a planar Paul trap

    NASA Astrophysics Data System (ADS)

    Clark, Robert; Brown, Kenneth; Labaziewicz, Jaroslaw; Richerme, Philip; Chuang, Isaac

    2006-05-01

    Traditional geometries for ion traps involve three dimensional structures which may be difficult to assemble in complex geometries demanded by applications such as large-scale quantum computation. Planar Paul traps provide an alternative approach [Chiaverini et. al., Quant. Inf. Comput. 5, 419 (2005)], in which the RF and DC electrodes are placed in a single plane, providing simpler fabrication and greater optical access to the trapped ions. We have designed and constructed a planar Paul trap using copper electrodes on a Rogers 4350 substrate. Strontium ions were loaded into this structure at UHV, and also at high vacuum using helium buffer gas cooling. The temperature of the ion cloud as a function of buffer gas pressure is compared to predictions from a model which includes ion-helium collisions and RF heating. The measured trap parameters, including secular frequencies, trap depth, and RF heating rates, agree well with a pseudopotential model based on finite-element electrostatic calculations.

  17. Stability Diagrams for Paul Ion Traps Driven by Two-Frequencies.

    PubMed

    Possa, Gabriela C; Roncaratti, Luiz F

    2016-07-14

    In this paper, we present and discuss stability diagrams for Paul traps driven by two ac voltages. In contrast to a typical Paul trap, here we suggest a secondary ac voltage whose frequency is twice the frequency of the primary one. The ratio between their amplitudes can be used to expand the region of stability and to access different states of motion of trapped ions. This provides a further mechanism to trap, cool, and manipulate single ions and also to improve the experimental framework where ion clouds and crystals can be prepared and controlled. Such approach opens the possibility of designing more sophisticated trapping architectures, leading to a wide variety of applications on ion trap research and mass analysis techniques. PMID:26881458

    1980-09-01

    This report evaluated the feasibility of installing a cogeneration system at the Paul Masson Vineyards Winery in Saratoga, California. The feasibility study explores the technical and economic features of a variety of cogeneration systems. The system recommended is a 290 kilowatt natural gas fired rich burning Otto cycle internal combustion engine-generator set. Waste heat recovery would produce an average of 1500 gallons per hour of 180F. process water and provide for a peak of 4500 gallons per hour for four hours per day. The system would produce 1,670,000 kilowatt-hours of electric energy per year, have a capital cost of $191,000, and have a payback period of 2.3 years. The project would save over 18 billion BTU's per year compared to separate generation of steam by Paul Masson and electricity by the utility. Atmospheric emissions can be sufficiently controlled by using a non-selective reduction catalytic converter.

    School-based clinics in St. Paul have provided comprehensive health services, including reproductive health care, for almost two decades. This study examines the effects of those clinics on the birthrates in their respective schools, using a newly developed methodology with numerous advantages over previous methods for estimating student birthrates. Confidentially matching the names of female students from school records with the names of mothers on birth records at the Department of Health provided birthrates for each of the St. Paul public high schools with clinics for each year between 1971 and 1986. The results show that birthrates fluctuated dramatically from one year to the next, but school-wide birthrates were not significantly lower in the years immediately following the opening of a clinic than in the years preceding it.

    The compact non-neutral plasma trap systems named "S-POD" have been developed at Hiroshima University as an experimental simulator of beam dynamics. S-POD is based either on a linear Paul trap or on a Penning trap and can approximately reproduce the collective motion of a relativistic charged-particle beam observed in the center-of-mass frame. We here employ the Paul trap system to investigate the behavior of an ion plasma near a dipole resonance. A simple method is proposed to calibrate the data of secular frequency measurements by using the dipole instability condition. We also show that the transverse density profile of an ion plasma in the trap can be estimated from the time evolution of ion losses caused by the resonance.

The central themes of Sartre's personal existence are shown to revolve around a struggle for self-definition and self-formation, rooted in the empathic failures of significant others during his formative years. It is argued that Sartre's experience of this struggle is mirrored and symbolized by the dialectic of being and nothingness which constitutes the central preoccupation of his philosophy.

    In March 1988, there was an outbreak of infection by a strain of Salmonella saint-paul with a distinctive antigenic marker. A total of 143 reports were received between 1 March and 7 June. Preliminary investigations suggested that raw beansprouts were a possible source of infection and a case-control study confirmed the association. S. saint-paul of the epidemic type was isolated from samples of beansprouts on retail sale in different cities in the United Kingdom and from mung bean seeds on the premises of the producer who was most strongly associated with cases. In addition, Salmonella virchow PT34 was isolated from samples of raw beansprouts and was subsequently associated with seven cases of infection. Four other serotypes of salmonella were also isolated from beansprouts. On 8 April the public were advised to boil beansprouts for 15 seconds before consumption, and the premises of the one producer associated with many cases were closed. As a result of these actions there was a significant decrease in the number of infections with S. saint-paul. PMID:2323356

    2016-03-01

    In this article, the purpose is less praising Paul Ricoeur's work than enlightening how the reader may actually find some practical, even operative help in this philosophical thought. This is particularly true regarding the fields of medicine and care. Paul Ricœur is now worldwide renowned as a major philosophical figure of the 20th century, and with books such as "Oneself as another", he occupies a very peculiar place at the crossroads of phenomenology and hermeneutics. Through both these philosophical traditions, Paul Ricœur offers some narrative ethics which may greatly sustain caregivers in their reflexion. Yet, the aim of this article is to focus on this philosopher who invites us to inhabit and play a role in this world. The goal is also to bring out the pragmatic ethics that this thinker developed, based on Aristotelian and Kantian traditions. Then, this piece seeks to demonstrate how the three stages of Ricoeur's "petite éthique" (his "small ethics"), which are the self's aim "for the good life with and for others in just institutions" can shed some light on the ethical consideration of politicals and caregivers.

    The structure of the acoustic basement of the eastern part of the St. Paul multifault transform fracture system hosts rift paleovalleys and a paleonodal depression that mismatch the position of the currently active zones. This displacement zone, which is composed of five fault troughs, is unstable in terms of the position of the rift segments, which jumped according to redistribution of stresses. The St. Paul system is characterized by straightening of the transform transition between two remote segments of the Mid-Atlantic Ridge (MAR). The eastern part of the system contains anomalous bright-spot-like reflectors on the flattened basement, which is a result of atypical magmatism, that forms the standard ridge relief of the acoustic basement. Deformations of the acoustic basement have a presedimentation character. The present-day deformations with lower amplitude in comparison to the basement are accompanied by acoustic brightening of the sedimentary sequence. The axial Bouguer anomalies in the east of the system continue to the north for 120 km from the active segments of the St. Paul system. Currently seismically active segments of the spreading system are characterized by increasing amplitudes of the E-W displacement along the fault troughs. Cross-correlation of the lengths of the active structural elements of the MAR zone (segments of the ridge and transform fracture zones of displacement) indicates that, statistically, the multifault transform fracture system is a specific type of oceanic strike-slip faults.

  13. Universal critical phenomena of the cloud --> crystal phase transition in the Paul trap: Powerlaws

    NASA Astrophysics Data System (ADS)

    Weiss, Daniel; Nam, Yunseong; Blümel, Reinhold

    N charged particles, simultaneously stored in a radio-frequency (rf) Paul trap, exhibit deterministic heating. Depending on the damping (γ) imparted to the system, these particles can exist in multiple phases, the most commonly found being the cloud and crystal phases. With a small γ, the particles exhibit gas-like behavior, where the heating and cooling equilibrate and a stable cloud results. For larger γ, the damping overcomes the heating and the particles are forced into the crystalline state. We explore the cloud --> crystal transition as a critical phenomenon. We find that the transition occurs at a critical value γc of the damping constant γ. We find that as a function of N, γc scales approximately like an iterated log law. We also present a universal power law, τm ~(γ -γc) - β , γ >γc , β > 0 , independent of both N and the Paul trap parameter a, depending only on the Paul trap parameter q, that describes the number of cycles necessary for the system to crystallize as a function of γ -γc .

    A common technique to measure ion-atom collision rates in a hybrid trap if the ions have no optical transitions (e.g. alkalis) is to monitor the fluorescence of the neutrals in the presence of a saturated linear Paul trap (LPT). We present numerical simulations, analytical calculations, and experimental results that show that the steady-state ion capacity of an LPT, Ns, exhibits nonlinear, nonmonotonic behavior as a function of ion loading rate, Λ. The steady state as a function of loading rate, Ns(Λ) , shows four distinct regions. In Region I, at the lowest Λ, Ns(Λ) increases monotonically. Then, Ns(Λ) reaches a plateau in Region II, before decreasing to a local minimum in Region III. Finally, in Region IV, Ns(Λ) once again increases monotonically. This behavior appears universal to any Paul trap, regardless of geometry or species trapped. We examine this behavior experimentally as a function of the q stability parameter of the Paul trap and simulate numerically the effect of the particular trap geometry on the onset of each of the four regions.

  15. A retrospective diagnosis of epilepsy in three historical figures: St Paul, Joan of Arc and Socrates.

    PubMed

    Muhammed, Louwai

    2013-11-01

    It has been suggested that undiagnosed epilepsy profoundly influenced the lives of several key figures in history. Historical sources recounting strange voices and visions may in fact have been describing manifestations of epileptic seizures rather than more supernatural phenomena. Well-documented accounts of such experiences exist for three individuals in particular: Socrates, St Paul and Joan of Arc. The great philosopher Socrates described a 'daimonion' that would visit him throughout his life. This daimonion may have represented recurrent simple partial seizures, while the peculiar periods of motionlessness for which Socrates was well known may have been the result of co-existing complex partial seizures. St Paul's religious conversion on the Road to Damascus may have followed a temporal lobe seizure which would account for the lights, voices, blindness and even the religious ecstasy he described. Finally, Joan of Arc gave a detailed narrative on the voices she heard from childhood during her Trial of Condemnation. Her auditory hallucinations appear to follow sudden acoustic stimuli in a way reminiscent of idiopathic partial epilepsy with auditory features. By analysing passages from historical texts, it is possible to argue that Socrates, St Paul and Joan of Arc each had epilepsy. PMID:24585826

    2014-01-01

    Digital flood-inundation maps for a 6.3-mile reach of the Mississippi River in Saint Paul, Minnesota, were developed through a multi-agency effort by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers and in collaboration with the National Weather Service. The inundation maps, which can be accessed through the U.S. Geological Survey Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/ and the National Weather Service Advanced Hydrologic Prediction Service site at http://water.weather.gov/ahps/inundation.php, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the U.S. Geological Survey streamgage at the Mississippi River at Saint Paul (05331000). The National Weather Service forecasted peak-stage information at the streamgage may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. In this study, flood profiles were computed for the Mississippi River by means of a one-dimensional step-backwater model. The hydraulic model was calibrated using the most recent stage-discharge relation at the Robert Street location (rating curve number 38.0) of the Mississippi River at Saint Paul (streamgage 05331000), as well as an approximate water-surface elevation-discharge relation at the Mississippi River at South Saint Paul (U.S. Army Corps of Engineers streamgage SSPM5). The model also was verified against observed high-water marks from the recent 2011 flood event and the water-surface profile from existing flood insurance studies. The hydraulic model was then used to determine 25 water-surface profiles for flood stages at 1-foot intervals ranging from approximately bankfull stage to greater than the highest recorded stage at streamgage 05331000. The simulated water-surface profiles were then combined with a geographic information system digital elevation model, derived from high-resolution topography

    The biharmonic or Navier-Stokes problems in the form of a coupled pair of Dirichlet problems (J. Smith, SIAM J. Numer. Anal. 5, 323 (1968) are numerically solved by using a two parameter point SOR method. We emphasize the dependance of the convergence domain on the discrete boundary formulae. Optimization of this SOR method is heuristic but can be foreseen with a satisfactory precision. The optimal region is rather large and although using imprecisely optimal parameters, we can greatly improve the classical block SOR method (L. W. Ehrlich, SIAM J. Numer. Anal. 8, 278 (1971); L. W. Ehrlich and M. M. Gupta, SIAM J. Numer. Anal. 12, 773 (1975); M. M. Gupta and R. P. Manohar, J. Comput. Phys. 31, 265 (1979); M.

  19. Paul's gospel and the rhetoric of apostolic rejection: A study of Galatians 1:15--17, 1 Corinthians 15:8, F. C. Baur, and the origins of Paul's Gentile mission

    NASA Astrophysics Data System (ADS)

    Mitchell, Matthew Wesley

    This dissertation proposes a new understanding of Paul's Gentile mission and its relationship to his so-called "conversion." This dissertation examines the origins of Paul's mission to the Gentiles, and locates it in his claims to have been personally commissioned to undertake such a mission by Jesus. Specifically, I argue that it is the rejection of Paul's claim to be an apostle, a claim founded upon his "conversion" experience, that precipitates his mission to the Gentiles. In arguing this view, I draw upon Ferdinand Christian Baur's nineteenth century theories concerning both the unreliability of Acts as a historical source, and his proposal of a clear division between Paul and the other apostles. In establishing the methodological and theoretical framework of the dissertation, I discuss the "New Perspective on Paul" that has dominated New Testament scholarship over the past thirty years. My study is also informed methodologically by the growing interest in rhetorical criticism among biblical scholars, although the emphasis of this dissertation bears more of a resemblance to the approach of the New Rhetoric than the categories of classical, Greco-Roman rhetoric. The textual component of this work falls into two stages. The first contains a full examination of Paul's "conversion passages" in Galatians 1:15--17 and 1 Corinthians 15:8, attempting to situate these seemingly unusual self-descriptions in their cultural contexts. The second involves an examination of F. C. Baur's presentation of Paul, and the reception of Baur's views among biblical scholars throughout the years following his scholarly activity. This dissertation makes two claims, each of which can stand on its own as an important contribution to scholarship. My first claim is that components of Baur's work support my proposal concerning Paul's Gentile mission and his experience of apostolic rejection, and that this proposal has much to commend it as an explanation of a perennial scholarly puzzle.

  20. Insights into the crystal chemistry of Earth materials rendered by electron density distributions: Pauling's rules revisited

    2014-05-20

    Pauling's first two rules are examined in terms of the accumulation of the electron density between bonded pairs of atoms for a relatively large number of oxide and silicate crystals and siloxane molecules. The distribution of the electron density shows that the radius of the oxygen atom is not fixed, but that it actually decreases systematically from ~1.40 Å to ~ 0.65 Å as the polarizing power and the electronegativity of the bonded metal atoms increase and the distribution of the O atom is progressively polarized and contracted along the bond vectors by the impact of the bonded interactions. The contractions result in an aspherical oxygen atom that displays as many different bonded “radii” as it has bonded interactions. The bonded radii for the metal atoms match the Shannon and Prewitt ionic radii for the more electropositive atoms like potassium and sodium, but they are systematically larger for the more electronegative atoms like aluminum, silicon and phosphorous. Pauling's first rule is based on the assumption that the radius of the oxide anion is fixed and that the radii of the cations are such that radius sum of the spherical oxide anion and a cation necessarily equals the separation between the cation-anion bonded pair with the coordination number of the cation being determined by the ratio of the radii of the cation and anion. In the case of the bonded radii, the sum of the bonded radii for the metal atoms and the oxide anion necessarily equals the bond lengths by virtue of the way that the bonded radii were determined in the partitioning of the electron density along the bond path into metal and O atom parts. But, the radius ratio for the O and M atoms is an unsatisfactory rule for determining the coordination number of the metal atom inasmuch as a bonded O atom is not, in general, spherical, and its size varies substantially along its bonded directions. But by counting the number of bond paths that radiate from a bonded atom, the coordination

    This article examines the life and work of Dr Paul Carton (1875-1947), a French physician who promoted 'naturist vegetarianism". His career and the evolution of his ideas were influenced by his own experience as a young man of treatment for tuberculosis, and by an anti-materialist philosophy. He developed a diet for his patients that became influential through his writings and through the activities of the French Naturist Society. Although by no means the only advocate of such ideas, Carton's influence has survived and can still be discerned in a close reading of the present-day French popular press. PMID:11695355

    St. Paul Island, AK, part of the Pribilofs, is an island remnant of the Bering Land Bridge, a possible coastal Picea refugium at the last glacial maximum, and a Holocene refugium for Mammuthus primigenius. A prior pollen record from Lake Hill indicates that St. Paul was predominantly herb tundra during the last glacial maximum followed by a shrub tundra in the early Holocene (Colinvaux, 1980). Subsequently, three radiocarbon dates on bones from Qagnax Cave indicate a last appearance of Mammuthus primigenius of 6.5 ka on St. Paul (Veltre et al. 2008). In March 2013, our team retrieved a 13.5 m composite core from Lake Hill to refine the extinction timing chronology, assess environmental change during the extinction interval, and test hypotheses about vegetation-megafauna feedback. This paper reports the results from modern botanical survey and analyses of fossil pollen, Sporormiella and other coprophilous spores, anchored by a new radiocarbon chronology consisting of seven AMS dates. Presently, bryophytes, Equisetum, Poaceae, Juncaceae, Salix and Viola commonly occur at the lake margin, accompanied increasingly by sedge meadow taxa with greater distance from the water's edge, especially Cyperaceae, Asteraceae, Apiaceae, Lupinus, Rubus and Valeriana. Sporormiella is consistently present in low abundances (2%, ~700 grains/cm3) in the late glacial and early Holocene until a drop to zero at 6,050 yr BP, remaining absent during the middle and late Holocene when it reappears at 1904 AD. The timing of Sporormiella decline and reappearance match well to the youngest mammoth bone date and the historic reintroduction of reindeer (1911 AD) on St. Paul Island. After 11 ka, major pollen types include Apiaceae, Poaceae, Cyperaceae, Artemisia and Salix, with lower abundances of Betula, Alnus and Ericaceae, consistent with herb tundra with some shrubs. Degraded Picea pollen grains are found at 12,240 yr BP in very low concentrations (223 grains/cm3), indicating long

    Due to the worldwide shortage of organs for transplantation, there has been an increased use of organs obtained after circulatory death alone. A protocol for this procedure has recently been approved by a major transplant consortium. This development raises serious moral and ethical concerns. Two renowned theologians of the previous generation, Paul Ramsey and Moshe Feinstein, wrote extensively on the ethical issues relating to transplantation, and their work has much relevance to current moral dilemmas. Their writings relating to definition of death, organ transplantation and the care of the terminally ill are briefly presented, and their potential application to the moral problem of organ donation after circulatory death is discussed.

    Two peridotite suites collected by submersible in the equatorial Atlantic Ocean (Hekinian et al., 2000) were studied for textures, modes, and in situ major and trace element compositions in pyroxenes. Dive SP12 runs along the immersed flank of the St. Peter and Paul Rocks islets where amphibole-bearing, ultramafic mylonites enriched in alkalies and incompatible elements are exposed (Roden et al., 1984), whereas dive SP03 sampled a small intra-transform spreading centre situated about 370 km east of the St. Peter and Paul Rocks. Both suites are characterized by undeformed, coarse-grained granular textures typical of abyssal peridotites, derived from residual mantle after ˜ 15% melting of a DMM source, starting in the garnet stability field. Trace element modelling, textures and lack of mineral zoning indicate that the residual peridotites were percolated, reacted and refertilized by ˜ 2.6% partially aggregated melts in the uppermost level of the melting region. This relatively large amount of refertilization is in agreement with the cold and thick lithosphere inferred by previous studies. Freezing of trapped melts occurred as the peridotite entered the conductive layer, resulting in late-stage crystallization of olivine, clinopyroxene, spinel, ± plagioclase. Chondrite-normalized REE patterns in clinopyroxenes from SP03 indicate that they last equilibrated with (ultra-) depleted partial melts. In contrast, REE concentrations in clinopyroxenes from SP12 display U and S shaped LREE-enriched patterns and the calculated compositions of the impregnating melts span the compositional range of the regional basalts, which vary from normal MORB to alkali basalt sometimes modified by chromatographic fractionation with no, or very limited, mineral reaction. Thus the mylonitic band forming the St. Peter and St. Paul Rocks ridge is not a fragment of subcontinental lithospheric mantle left behind during the opening of the Central Atlantic, nor the source of the alkaline basalts

    The purpose of this analysis is to estimate how much electricity the redeveloped Ford Motor Company assembly plant site in St. Paul, Minnesota, might consume under different development scenarios and how much rooftop photovoltaic (PV) generation might be possible at the site. Because the current development scenarios are high-level, preliminary sketches that describe mixes of residential, retail, commercial, and industrial spaces, electricity consumption and available rooftop area for PV under each scenario can only be grossly estimated. These results are only indicative and should be used for estimating purposes only and to help inform development goals and requirements moving forward.

  9. Our perception of the mast cell from Paul Ehrlich to now

    2010-01-01

    Just over a century ago Paul Ehrlich received the Nobel Prize for his studies of immunity. This review describes one of his legacies, the histochemical description of the mast cell, and the research that has ensued since then. After a long period of largely descriptive studies, which revealed little about the biological role of the mast cell, the field was galvanized in the 1950s by the recognition that the mast cell was the main repository of histamine and a key participant in anaphylactic reactions. Although the mast cell was long-viewed in these terms, recent research has now shown that the mast cell also plays a key role in innate and adaptive immune responses, autoimmune disease, and possibly tissue homeostasis by virtue of its expression of a diverse array of receptors and biologically active products. In addition, the responsiveness of mast cells to immunological and pathological stimulants is highly modulated by the tissue cytokine environment and by synergistic, or inhibitory, interactions among the various mast cell receptor systems. This once enigmatic cell of Paul Ehrlich has proved to be both adaptable and multifunctional. PMID:19130582

    A hydrologic reconnaissance of the southeastern part of St. Paul Island, Pribilof Islands, Alaska, was made in August 1979 to determine if sufficient freshwater is available for a proposed harbor and fish-processing facility. Only three wells were being used in 1979, two by the community of St. Paul and one by the Coast Guard Loran facility. All wells are in the southeastern part of the island. The island has no established surface drainage, and no springs were found on the eastern part of the island during the survey. Drainage of ground-water from the island is assumed to be by seepage through the sandy deposits along the east coast and possibly by undersea discharge elsewhere on the island. On the basis of present well yields, amount of freshwater inferred to be present below the water table, and potential recharge from precipitation, it is concluded that it should be possible to design a well field in the southeastern part of the island that could yield more than a million gallons per day without danger of inducing saline water into the well field. The water is of good chemical quality. (USGS)

  11. Wave packet dynamics of an atomic ion in a Paul trap

    Using numerical simulations of the time-dependent Schrödinger equation, we study the full quantum dynamics of the motion of an atomic ion in a linear Paul trap. Such a trap is based on a time-varying, periodic electric field and hence corresponds to a time-dependent potential for the ion, which we model exactly. We compare the center-of-mass motion with that obtained from classical equations of motion, as well as to results based on a time-independent effective potential. We also study the oscillations of the width of the ion’s wave packet, including close to the border between stable (bounded) and unstable (unbounded) trajectories. Our results confirm that the center-of-mass motion always follows the classical trajectory, that the width of the wave packet is bounded for trapping within the stability region, and therefore that the classical trapping criterion is fully applicable to quantum motion.

  12. A short biography of Paul A. M. Dirac and historical development of Dirac delta function

    Debnath, Lokenath

    2013-12-01

    This paper deals with a short biography of Paul Dirac, his first celebrated work on quantum mechanics, his first formal systematic use of the Dirac delta function and his famous work on quantum electrodynamics and quantum statistics. Included are his first discovery of the Dirac relativistic wave equation, existence of positron and the intrinsic spin and helicity of electrons. Special attention is given to Dirac's original visionary work on the existence of the magnetic monopole, and on his Large Number Hypothesis that led to the conclusion that physical quantities universally considered as constant of nature are not really constants, but they vary with cosmological time. Some concluding remarks with personal reminiscence are added in the end of the paper.

    The BOA beamline at the Swiss spallation neutron source SINQ at Paul Scherrer Institut is a flexible instrument used mainly for testing novel techniques and devices for neutron scattering and optics, but, due to the large and relatively homogeneous field of view, it can be successfully used for experiments in the field of neutron imaging. The beamline allows also for the exploitation of advanced imaging concepts such as polarized neutron imaging and diffractive neutron imaging. In this paper we present the characterization of the BOA beamline in the light of its neutron imaging capabilities. We show also the different techniques that can be employed there as user-friendly plugins for non-standard neutron imaging experiments.

    Here we present results stemming from the first prototype of the Neutron Microscope instrument at Paul ScherrerInstitut (PSI). The instrument is based on a very thin gadolinium oxysulfide (Gd2O2S:Tb+) scintillator screen and a magnifying optics. The Neutron Microscope prototype has been tested at the ICON and the BOA beamlines at PSI and sub-10 μm features can be clearly resolved on a focussed ion beam (FIB) enhance test object - a gadolinium-based Siemens star. The spatial resolution of the images of the gadolinium-based Siemensstar assessed by Fourier ring correlation was about 7.6 μm. The outlook for future improvement of the Neutron Microscope system is presented.

  15. Persistence rates and detection probabilities of oiled king eider carcasses on St Paul Island, Alaska

    Fowler, A.C.; Flint, P.L.

    1997-01-01

    Following an oil spill off St Paul Island, Alaska in February 1996, persistence rates and detection probabilities of oiled king eider (Somateria spectabilis) carcasses were estimated using the Cormack-Jolly-Seber model. Carcass persistence rates varied by day, beach type and sex, while detection probabilities varied by day and beach type. Scavenging, wave action and weather influenced carcass persistence. The patterns of persistence differed on rock and sand beaches and female carcasses had a different persistence function than males. Weather, primarily snow storms, and degree of carcass scavenging, diminished carcass detectability. Detection probabilities on rock beaches were lower and more variable than on sand beaches. The combination of persistence rates and detection probabilities can be used to improve techniques of estimating total mortality.

  17. Control Of Screening Of A Charged Particle In Electrolytic Aqueous Paul Trap

    Park, Jae Hyun; Krstic, Predrag S.

    2011-06-01

    Individual charged particles could be trapped and confined by the combined radio-frequency and DC quadrupole electric field of an aqueous Paul trap. Viscosity of water improves confinement and extends the range of the trap parameters which characterize the stability of the trap. Electrolyte, if present in aqueous solution, may screen the charged particle and thus partially or fully suppress electrophoretic interaction with the applied filed, possibly reducing it to a generally much weaker dielectrophoretic interaction with an induced dipole. Applying molecular dynamics simulation we show that the quadrupole field has a different effect at the electrolyte ions and at much heavier charged particle, effectively eliminating the screening by electrolyte ions and reinstating the electrophoretic confinement.

    This paper proposes the use of the two-dimensional continuous Paul wavelet transform to extract the phase of spatial carrier fringe patterns. The proposed algorithm has been tested using computer-generated and real fringe patterns, and these tests have demonstrated the suitability of the proposed technique for the phase demodulation of fringe patterns. Additionally, this algorithm is compared to three two-dimensional continuous wavelet algorithms that have figured prominently in the literature, specifically the Morlet, advanced Morlet and fan mother wavelets. This comparison has revealed that the proposed algorithm outperforms the other three mother wavelets in terms of its suitability for extracting the phase of fringe patterns that exhibit large phase variations.

    2015-11-28

    We present models for a heteronuclear diatomic molecular ion in a linear Paul trap in a rigid-rotor approximation, one purely classical and the other where the center-of-mass motion is treated classically, while rotational motion is quantized. We study the rotational dynamics and their influence on the motion of the center-of-mass, in the presence of the coupling between the permanent dipole moment of the ion and the trapping electric field. We show that the presence of the permanent dipole moment affects the trajectory of the ion and that it departs from the Mathieu equation solution found for atomic ions. For the case of quantum rotations, we also evidence the effect of the above-mentioned coupling on the rotational states of the ion.

    The results presented here demonstrate that the Paul Trap Simulator Experiment (PTSX) simulates the propagation of intense charged particle beams over distances of many kilometers through magnetic alternating-gradient (AG) transport systems by making use of the similarity between the transverse dynamics of particles in the two systems. Plasmas have been trapped that correspond to normalized intensity parameters s = wp2 (0)/2wq2 * 0.8, where wp(r) is the plasmas frequency and wq is the average transverse focusing frequency in the smooth-focusing approximation. The measured root-mean-squared (RMS) radius of the beam is consistent with a model, equally applicable to both PTSX and AG systems that balances the average inward confining force against the outward pressure-gradient and space-charge forces. The PTSX device confines one-component cesium ion plasmas for hundreds of milliseconds, which is equivalent to over 10 km of beam propagation.

  2. Psychoanalysis, creativity, and hope: forward edge strivings in the life and work of choreographer Paul Taylor.

    PubMed

    Press, Carol M

    2005-01-01

    Psychoanalysis and creativity are not interchangeable enterprises; however, both creativity and psychoanalysis promise the hope of transformation. But hope may be fragile. Healthy aspects of self may hide and diminish hope to protect it against invasion from toxic pathological patterns. Hope may be rekindled by an empathically responsive environment and the reengagement of healthy forward edge strivings. Psychoanalysis illustrates creativity as a conduit for hope. Modern dance choreographer Paul Taylor's 1988 autobiography, Private Domain, describes Taylor's hope and strivings through creative engagement. Unfortunately, when Taylor's body inevitably falters after years of performing, he is unprepared psychologically to cope successfully. Taylor's sense of self begins to fragment and his forward edge strivings to decay. Eventually, Taylor collapses on stage from drug addiction and illness; his performing career crashes to an end. Taylor must search for his forward edge strivings with hope. Psychoanalysis illuminates Taylor's journey to find hope, motivation, meaningful intention, and transformation through creativity and dance-making. PMID:15953780

    A new approach to β-delayed neutron spectroscopy has been demonstrated that circumvents the many limitations associated with neutron detection by instead inferring the decay branching ratios and energy spectra of the emitted neutrons by studying the nuclear recoil. Using the Beta-decay Paul Trap, fission-product ions were trapped and confined to within a 1-mm{sup 3} volume under vacuum using only electric fields. Results from recent measurements of {sup 137}I{sup +} and plans for development of a dedicated ion trap for future experiments using the intense fission fragment beams from the Californium Rare Isotope Breeder Upgrade (CARIBU) facility at Argonne National Laboratory are summarized. The improved nuclear data that can be collected is needed in many fields of basic and applied science such as nuclear energy, nuclear astrophysics, and stockpile stewardship.

    In 1877 Louis Paul Cailletet in France and Raoul Pictet in Switzerland liquefied oxygen in the form of a mist. The liquefaction of the first of the so-called permanent gases heralded the birth of low-temperature research and is often described in the literature as having started a ‘race’ for attaining progressively lower temperatures. In fact, between 1877 and 1908, when helium, the last of the permanent gases, was liquefied, there were many priority disputes—something quite characteristic of the emergence of a new research field. This paper examines Cailletet's path to the liquefaction of oxygen, as well as a debate between him and the Polish physicist Zygmunt Wróblewski over the latter's contribution to the liquefaction of gases.

    Quantum tunnelling is a common fundamental quantum mechanical phenomenon that originates from the wave-like characteristics of quantum particles. Although the quantum tunnelling effect was first observed 85 years ago, some questions regarding the dynamics of quantum tunnelling remain unresolved. Here we realize a quantum tunnelling system using two-dimensional ionic structures in a linear Paul trap. We demonstrate that the charged particles in this quantum tunnelling system are coupled to the vector potential of a magnetic field throughout the entire process, even during quantum tunnelling, as indicated by the manifestation of the Aharonov-Bohm effect in this system. The tunnelling rate of the structures periodically depends on the strength of the magnetic field, whose period is the same as the magnetic flux quantum φ0 through the rotor [(0.99 ± 0.07) × φ0].

    Dr. Paul Moore pioneered the use of high-speed cinematography for observation of normal and abnormal vocal fold vibrations during phonation. His analysis of the glottal area waveform, opening and closing speed index, and open quotient from the high-speed films were labor intensive but relevant today. With advances in digital image capture and automated image extraction techniques, stroboscopy and high-speed images of vocal fold vibration may be analyzed with objective measures. Digital high-speed image capture in color is now clinically practical at high resolution. Digital kymography now allows analysis of the vibratory waveform from each vocal fold. Serial capture and comparison can document changes in vibratory function with treatment. Quantification of vocal fold vibration using such techniques is now practical. This is a review of vocal fold vibration capture and analysis techniques since Dr. Moore. PMID:24094798

    2004-07-01

    The evolution of a Pleistocene to Holocene basaltic volcanic field in the back-arc region of the Aleutian subduction system is investigated at St. Paul Island, Alaska, one of the youngest eruptive centers in the Bering Sea basalt province. New 40Ar/ 39Ar and 14C age determinations indicate that subaerial volcanic activity forming the island began as early as 540 ka and has continued nearly to the present; the youngest eruption occurred approximately 3230 years BP. Magmas erupted on St. Paul are basaltic with MgO contents ranging from 14 to 4 wt.% and phenocryst assemblages of olivine+clinopyroxene±plagioclase; all are alkalic. The surface of St. Paul is composed mainly of numerous tephra cones surrounded by coalescing, low-viscosity pahoehoe lava flows. A central highland spans the island from east to west and is constructed of relatively young eruptive centers where rocks show a minimum of weathering and little deformation by faulting. In contrast, older lava flows forming the wave-eroded base of the island are gently to moderately tilted and faulted. Geochronologic, stratigraphic, and geochemical data indicate that eruptive styles on St. Paul evolved from early, mostly effusive eruptions of chemically little evolved lavas that form the base of the island, to more explosive monogenetic scoria cones, to polygenetic centers forming shields by repeated effusive eruptions of evolved low-viscosity lavas. Localization of the monogenetic and polygenetic centers appears to be related to east-west and northeast-southwest trending fault and fissure systems, with polygenetic centers located at intersections of major structures. The combined volcanic and compositional changes on St. Paul Island suggest that the magmatic system as a whole may be trending toward eruption of more evolved magmas related to the progressive development of crustal magma chambers in which crystal fractionation and magmatic differentiation are occurring.

D. and Hans von Leden, M.D. The films received two awards for best scientific cinematography from two different international film festivals in Italy in 1957. These films present ultra high-speed cinematographic accounts on the workings of the human vocal folds during various phonatory and ventilatory activities. These films were captured at speeds of 2000 to 5000 frames-per-second via an ingeniously arranged laryngeal mirror viewing device. Such speeds were revolutionary six decades ago. Technology currently allows us to film laryngeal behavior at speeds of up to 16,000 frames-per-second using digital recordings. However, the ultra high-speed films by Paul and Hans remain a beacon for anyone sincerely interested in how the smallest instrument of sound production works, and how it is subjected to failure by intrinsic or extrinsic factors.

    The eminent Greek physician Paul of Aegina, native of the Saronic island Aegina and pupil of the Alexandrian School, understood both exotropia and endotropia, his designation for esotropia and proposed therapeutic measures for their treatment during baby or toddler age. He had introduced an innovative method for the newborns to have a straight vision, "the congenital strabismus of the newborns must be treated with the placement of a facial mask (with 2 open holes in the middle axes of the eyes), so that the babies could only see in a straight line", combined with a small oil lamp to assure a direct eye alignment. Although not even a diagram of the masks was saved until nowadays, Paul was the first to suggest the early correction of the eyes deviation, and considered to be the father of orthoptics.

    The American dream altered. In the 19th century, it was focused on male success in the marketplace. With the rise of the consumer culture, ideals changed. Women were brought in, as companionate marriage, home ownership, and a successful domestic life with children became central in American life. Since the mid-sixties, singer-songwriter Paul Simon has been writing songs reflecting these changes. He has two songs with America in the title, and is one of the few rock stars that write extensively about marriage and parenting. He also writes about love as romance, with a spouse, and towards offspring. Simon too composes songs about affluence, technology, and what brings happiness and joy. His work illuminates the United States in what he says is "the age's most uncertain hour." He believed that affluence was a key to our fulfillment. The changes in American life since the 1970s, show that much of what was held as ideal, has been through troubled times. We can gain insight into the fate of the American dream through Simon's songs.

    Paul trap working in the second stability region has long been recognized as a possible approach for achieving high-resolution mass spectrometry (MS), which however is still far away from the experimental implementations because of the narrow working area and inefficient ion trapping. Full understanding of the ion motional behavior is helpful for solving the problem. In this article, the ion motion in a superimposed octopole field, which was characterized by the nonlinear Mathieu equation, was solved analytically using Poincare-Lighthill-Kuo (PLK) method. This method equivalently described the nonlinear disturbance by an effective quadrupole field with perturbed Mathieu parameters, a(u) and q(u), which would bring huge convenience in the studies of nonlinear ion dynamics and was, therefore, used for rapid evaluation of the nonlinear effects of ion motion. Fourth-order Runge-Kutta method (4th R-K) indicated the error of PLK for characterizing the frequency shift of ion motion was within 15%. PMID:25183226

  8. Conspiracies of immanence: Paul Tillich, Pierre Teilhard de Chardin and C.G. Jung.

    Jung's psychology proffers a sustained reflection on the traditional religious question of the relation of divine transcendence to immanence. On this issue his psychology affirms a position of radical immanence in its contention that the experience of divinity is initially wholly from within. Though this position remains on the periphery of religious and theological orthodoxy Jung is not alone in holding it among moderns. Paul Tillich adopts a similar stance with his controlling symbols of the divine as 'Ground of Being' and 'Depth of Reason'. Pierre Teilhard de Chardin understands divinity as the experiential energy of evolution itself working within nature and humanity toward greater configurations of universal communion as the basis of community. All of Jung's master symbols of individuation assume such an understanding of immanence uniting individual and totality. His psychology strongly suggests and contributes to the current emergence of a new religious sensitivity based on the awareness of the intra-psychic origin of all religions. In his later writings he held out such a position as a significant alternative to genocide. PMID:25610962

    The Amsterdam-St. Paul (ASP) plateau is located in the central part of the Indian Ocean and results from the interaction between the ASP hot spot and the Southeast Indian Ridge (SEIR). It is located near the diffuse boundary between the Capricorn and Australian plates. The seamount chain of the Dead Poets (CDP) is northeast of the ASP plateau and may represent older volcanism related to the ASP hot spot; this chain consists of two groups of seamounts: (1) large flat-topped seamounts formed 8-10 Ma and (2) smaller conical seamounts formed during the last 2 Myr. The ASP hot spot has produced two pulses of magmatism that have been ponded under the ASP plateau and erupted along the divergent boundary between the Capricorn and Australian plates. The N65° orientation of the CDP as well as the seamount's elongated shapes support an opening motion between the Capricorn and Australian plates along a suture oriented in the N155° direction. This motion compared to the Antarctic plate amounts to an apparent velocity of 7.7 cm/yr northeastward for the Capricorn-Australian block. This motion does not fit with a fixed plume model. We suggest, therefore, that the ASP plume experienced a motion of about 1-2 cm/yr to the SW, which is opposite to the asthenospheric flow in this region and suggests a deep-seated plume.

    Projective readout of quantum information stored in atomic qubits typically uses state-dependent CW laser-induced fluorescence. This method requires an often sophisticated imaging system to spatially filter out the background CW laser light. We present an alternative approach that instead uses simple pulse sequences from a mode-locked laser to affect the same state-dependent excitations in less than 1 ns. The resulting atomic fluorescence occurs in the dark, allowing the placement of non-imaging detectors right next to the atom to improve the qubit state detection efficiency and speed. We also study 2D Coulomb crystals of atomic ions in an oblate Paul trap. We find that crystals with hundreds of ions can be held in the trap, potentially offering an alternative to the use of Penning traps for the quantum simulation of 2D lattice spin models. We discuss the classical physics of these crystals and the metastable states that are supported in 2D. This work is supported by the US Army Research Office.

    The cold neutron spectrum of the Beamline for neutron Optics and other Applications (BOA) at Paul Scherrer Institut enables high contrast neutron imaging because neutron cross sections for many materials increase with neutron wavelength. However, for many neutron imaging applications, spatial resolution can be as important as contrast. In this paper the neutron transmission imaging capabilities of an MCP/Timepix detector installed at the BOA beamline are presented, demonstrating the possibilities for studying sub-20 μm features in various samples. In addition to conventional neutron radiography and microtomography, the high degree of neutron polarization at the BOA beamline can be very attractive for imaging of magnetic fields, as demonstrated by our measurements. We also show that a collimated cold neutron beamline combined with a high resolution detector can produce image artifacts, (e.g. edge enhancements) due to neutron refraction and scattering. The results of our experiments indicate that the BOA beamline is a valuable addition to neutron imaging facilities, providing improved and sometimes unique capabilities for non-destructive studies with cold neutrons.

  12. Paul Gray's narrowing scope: a "developmental lag" in his theory and technique.

    PubMed

    2006-01-01

    A cental thesis of Paul Gray's work is that a "developmental lag" pervades modern psychoanalysis in its failure to assimilate and apply knowledge gained about the role of the unconscious ego in intrapsychic life. But Gray himself, it is proposed, has become a victim of a new "developmental lag," of his own construction. As he somewhat single-mindedly pursued the ramifications of his "developmental lag" concept, Gray may have foreclosed on some noteworthy ideas developing around him. The most important example is his claim--herein refuted--that proper interpretive technique can avoid being infused with transference. He also seems to have rejected the theoretical importance of the internalization of the analyst and the clinical usefulness of countertransference. While emphasizing defense analysis, he ignores defenses such as splitting, denial, and disavowal as substantive problems for his technique of close-process attention. Gray's "undoing" of the rapprochement between "ego analysis" and "id analysis" by viewing the matter as an either-or proposition undermines the very real value of his contribution to the field.

    In 2010, Coxiella burnetii was identified at a high prevalence in the placentas of Northern fur seals (Callorhinus ursinus) collected at a single rookery on St. Paul Island Alaska; an area of the United States where the agent was not known to be present. As contamination was hypothesized as a potential cause of false positives, but nothing was known about environmental C. burnetii in the region, an environmental survey was conducted to look for the prevalence and distribution of the organism on the island. While environmental prevalence was low, two strains of the organism were identified using PCR targeting the COM1 and IS1111 genes. The two strains are consistent with the organism that has been increasingly identified in marine mammals as well as a strain type more commonly found in terrestrial environments and associated with disease in humans and terrestrial animals. Further work is needed to elucidate information regarding the ecology of this organism in this region, particularly in association with the coastal environment. PMID:22747976

    The Proton Irradiation Facility (PIF) has been designed and constructed, in cooperation between Paul Scherrer Institute (PSI) and European Space Agency (ESA), for terrestrial proton testing of components and materials for spacecraft. Emphasis has been given to generating realistic proton spectra encountered by space-flights at any potential orbit. The facility, designed in a user-friendly manner, can be readily adapted to the individual requirements of experimenters. It is available for general use serving also in testing of radiation monitors and for proton experiments in different scientific disciplines. The Radiation Environment Monitor REM has been developed for measurements of the spacecraft radiation conditions. Two instruments were launched into space, one into a Geo-stationary Transfer Orbit on board of the STRV-1b satellite and one into a Low Earth Orbit on the Russian MIR station. The next generation of monitors (SREMs--Standard REMs) is currently under development in partnership of ESA, PSI and Contraves-Space. They will operate both as minimum intrusive monitors, which provide radiation housekeeping data and alert the spacecraft when the radiation level crosses allowed limits and as small scientific devices measuring particle spectra and fluxes. Future missions as e.g. INTEGRAL, STRV-1c and PROBA will be equipped with new SREMs. PMID:11770526

    Miniature gas chromatography (GC) and miniature mass spectrometry (MS) instrumentation has been developed to identify and quantify the chemical compounds present in complex mixtures of gases. The design approach utilizes micro-GC components coupled with a Paul quadrupole ion trap (QIT) mass spectrometer. Inherent to the system are high sensitivity, good dynamic range, good QIT resolution, low GC flow-rates to minimize vacuum requirements and the need for consumables; and the use of a modular approach to adapt to volatile organic compounds dissolved in water or present in sediment. Measurements are reported on system response to gaseous species at concentrations varying over four orders of magnitude. The ability of the system to deal with complicated mixtures is demonstrated, and future improvements are discussed. The GC/QIT system described herein has a mass, volume and power that are, conservatively, one-twentieth of those of commercial off-the-shelf systems. Potential applications are to spacecraft cabin-air monitoring, robotic planetary exploration and trace-species detection for residual gas analysis and environmental monitoring.

    Background The DePaul Symptom Questionnaire (DSQ) was developed to provide a structured approach for collecting standardized symptomatology and health history information to allow researchers and clinicians to determine whether a patient meets the diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), myalgic encephalomyelitis (ME), and/or chronic fatigue syndrome (CFS). Purpose The purpose of this study was to examine the test-retest reliability of the DSQ. Methods Test-retest reliability of the measure was examined with a sample of 26 adults self-identifying as having either ME/CFS, ME and/or CFS and 25 adults who did not self-identify as having these illnesses and were otherwise healthy controls. Results Overall, the majority of items on the DSQ exhibited good to excellent test-retest reliability, with Pearson’s or kappa correlation coefficients that were 0.70 or higher. Conclusions Thus, the present study suggests that the DSQ is a reliable diagnostic measure that can provide a standardized way of examining illness constructs and symptomatology among patients who identify as having ME/CFS, ME and/or CFS.

    We report on the construction and characterization of an apparatus for quantum information experiments using 88Sr+ ions. A miniature linear radio-frequency (rf) Paul trap was designed and built. Trap frequencies above 1 MHz in all directions are obtained with 50 V on the trap end-caps and less than 1 W of rf power. We encode a quantum bit (qubit) in the two spin states of the S 1/2 electronic ground-state of the ion. We constructed all the necessary laser sources for laser cooling and full coherent manipulation of the ions' external and internal states. Oscillating magnetic fields are used for coherent spin rotations. High-fidelity readout as well as a coherence time of 2.5 ms are demonstrated. Following resolved sideband cooling the average axial vibrational quanta of a single trapped ion is bar{n}=0.05 and a heating rate of dot{bar{n}}=0.016 ms^{-1} is measured.

    It is well known that ions stored in a Paul trap, one of the most versatile tools in atomic, molecular, and optical (AMO) physics, may undergo a transition from a disordered cloud state to a geometrically well-ordered crystalline state, the Wigner crystal. In this paper we predict that close to the transition, the average lifetime τ¯m of the metastable cloud follows a power law, τ¯m˜(γ-γc) -β , where γc is the value of the damping constant at which the transition occurs. The exponent β depends on the trap control parameter q , but is independent of both the number of particles N stored in the trap and the trap control parameter a , which determines the shape (oblate, prolate, or spherical) of the ion cloud. In addition, we find that for given a and q , γc scales approximately like γc=C ln[ln(N ) ] +D as a function of N , where C and D are constants. Our predictions may be tested experimentally with equipment already available at many AMO laboratories. In addition to their importance in AMO trap physics, we also discuss possible applications of our results to other periodically driven many-particle systems, such as, e.g., particle accelerator beams, and, based on our trap results, conjecture that power laws characterize the phase transition to the Wigner crystal in all such systems.

  1. Models for biological research: the theory and practice of Paul Ehrlich.

    PubMed

    Travis, Anthony S

    2008-01-01

    In the late-nineteenth and early-twentieth centuries, the study of the living world placed considerable reliance on applied chemistry and chemical concepts. Paul Ehrlich, the subject of this paper, adopted from the mid-1870s principles of organic chemistry to devise procedures for use in histology, to suggest features of cellular structure, and to draw up cartoons that explained the nature of immunity. From a distinctly molecular basis, he devised meaningful experimental strategies and was inspired to develop speculative but effective theoretical models along the same lines that chemists had used to resolve problems of molecular structure and behavior. Thus, Ehrlich suggested that combining power and toxicity were independent properties of the antigen toxin. He succeeded to classify synthetic dyestuffs as stains, to use them for investigating molecular combustion, to adapt theories of dyeing to develop models for both combustion and immunity, and to exploit the properties of dyes in the development of chemotherapy. Ehrlich not only speculated on the behavior of synthetic chemicals toward his model of the protoplasm but also invoked biological specificity, a concept that would have a tremendous impact on immunology, drug development, and molecular biology.

    Minneapolis-St. Paul is recognized as a prime example of health care competition. Policymakers and others have been asked to look to the Twin Cities as a model upon which to base new competitive initiatives in the health care sector. Yet little is known about the impact of Health Maintenance Organizations (HMOs) on other health care providers. This study examines the effects of the area's seven health maintenance organizations on the local hospital community. Three questions are addressed. First, is the situation in the Twin Cities unique? A comparison of case study findings and the available literature together with hospital data from similarly HMO-penetrated markets suggests that the Twin Cities' hospital market is indeed different. Second, what is the nature of hospital-HMO interaction? The flexibility of contracting apparently allows hospitals to affiliate successfully with an HMO under a variety of service and reimbursement agreements. Third, what effect has HMO activity had on community-wide utilization? While HMO enrollees clearly use fewer hospital days and the trend in the community is toward fewer days, attributing the change to HMOs is difficult. A large portion of the differences between HMO and community-wide utilization levels is attributable to differences in population. PMID:10309856

    There emerges a world epidemic of diabetes, afflicting over 3.8 billion people globally. The socio-economic burden of this disorder is tremendous and there is an urgent need to solve the problems incurred from this disorder and to establish an efficient way of prevention and treatment. Fundamental pathology of diabetes has been too diverse to reach a simple etiology and the mechanisms of how the lesions specific to diabetes develop are yet to be clear. Nevertheless, there has been slow but significant advancement in the understanding of the disease based on characterization of the salient features of pathological lesions in human diabetic subjects. Progressive decline of islet β cells associated with increased α cell volume density was found to account for clinical manifestation of hypoinsulinemia and hyperglucagonemia in type 2 diabetes. Concurrently, signs of complications represented by distal nerve fiber loss in the skin commences from the beginning of this disease. Thus the pathological studies disclosed the major attributes in this disorder targeting the islet of pancreas and epidermal nerve, both of which were discovered by Paul Langerhans more than 140 years ago. In this review, I attempt to summarize the progress in pathology of diabetes which Langerhans opened this field. PMID:25708009

    The Amsterdam-St Paul (ASP) oceanic plateau results from the interaction between the ASP hot spot and the Southeast Indian ridge. A volcanic chain, named the Chain of the Dead Poets (CDP), lies to its northward tip and is related to the hot spot intraplate activity. The ASP plateau and CDP study reveals that ASP plume composition is inherited from oceanic crust and pelagic sediments recycled in the mantle through a 1.5 Ga subduction process. The ASP plateau lavas have a composition (major and trace elements and Sr-Nd-Pb-Hf isotopes) reflecting the interaction between ASP plume and the Indian MORB mantle, including some clear DUPAL input. The Indian upper mantle below ASP plateau is heterogeneous and made of a depleted mantle with lower continental crust (LCC) fragments probably delaminated during the Gondwana break-up. The lower continental crust is one of the possible reservoirs for the DUPAL anomaly origin that our data support. The range of magnitude of each end-member required in ASP plateau samples is (1) 45% to 75% of ASP plume and (2) 25% to 55% of Indian DM within 0% to a maximum of 6% of LCC layers included within. The three end-members involved (plume, upper mantle and lower continental crust) and their mixing in different proportions enhances the geochemical variability in the plateau lavas. Consequently, the apparent composition homogeneity of Amsterdam Island, an aerial summit of the plateau, may result from the presence of intermediate magmatic chambers into the plateau structure.

    St. Paul Island, one of the Alaskan Pribilof Islands, is located in the Bering Sea about 1100 km WSW of Anchorage, Alaska. Geologically, St. Paul's nearsurface lithology consists of basaltic lava flows and sills, with minor amounts of glacial sediments. To better understand the subsurface structure of St. Paul island, the U.S. Geological Survey acquired a series of high-resolution seismic imaging profiles across the island in June, 2000. The longest seismic profile is approximately 1.8-km-long and trends ENE. Shot and geophone spacing was 5 m, recorded with 162 channels. Seismic sources were generated using a Betsy Seisgun in { ~}0.3 m-deep holes. Approximately 2 s of data were recorded at a 0.5-ms sampling rate. Our study was designed to investigate the relationship between ground-water flow, basement rocks, and faults on St. Paul Island in an attempt to mitigate the effects of subsurface chemical contaminants. Seismic velocities range from about 500 m/s in the near surface to about 5000 m/s at varying depths, some of the high velocity layers appear as shallow as 40 m below the surface. The reflection data show a thin vaneer of sediments overlying layered basalts. Layered basalts vary in thickness from about 5 to 40 m near the surface, and these layers are faulted in places. The groundwater supply for St. Paul is derived from a shallow-depth water table that is, in places, a mixture of seawater and freshwater (Anderson, 1976). Vertical and lateral flow of ground-water is affected by the depth to basement rocks, which are believed to be largely impermeable and thus restrict the flow of ground-water. In addition, a series of observed faults that have vertically displaced basement rocks may act as barriers or as conduits to the flow of ground-water. In unconsolidated sediments, the ground-water table typically has velocities of { ~}1500 m/s. Using this velocity criteria, our data suggest that the ground-water table varies between 0 and 25 m depth along the profile

    In comparison with numerical methods, theoretical characterizations of ion motion in the nonlinear Paul traps always suffer from low accuracy and little applicability. To overcome the difficulties, the theoretical harmonic balance (HB) method was developed, and was validated by the numerical fourth-order Runge-Kutta (4th RK) method. Using the HB method, analytical ion trajectory and ion motion frequency in the superimposed octopole field, ε, were obtained by solving the nonlinear Mathieu equation (NME). The obtained accuracy of the HB method was comparable with that of the 4th RK method at the Mathieu parameter, q = 0.6, and the applicable q values could be extended to the entire first stability region with satisfactory accuracy. Two sorts of nonlinear effects of ion motion were studied, including ion frequency shift, Δβ, and ion amplitude variation, Δ(C(2n)/C0) (n ≠ 0). New phenomena regarding Δβ were observed, although extensive studies have been performed based on the pseudo-potential well (PW) model. For instance, the |Δβ| at ε = 0.1 and ε = -0.1 were found to be different, but they were the same in the PW model. This is the first time the nonlinear effects regarding Δ(C(2n)/C0) (n ≠ 0) are studied, and the associated study has been a challenge for both theoretical and numerical methods. The nonlinear effects of Δ(C(2n)/C0) (n ≠ 0) and Δβ were found to share some similarities at q < 0.6: both of them were proportional to ε, and the square of the initial ion displacement, z(0)(2).

    There have been an increasing number of reports of postamputation pain and problems linked to phantom limbs over recent years, particularly in relation to war-related amputations. These problems, which are often poorly understood and considered rather mysterious, are still relevant because they are difficult to treat medically. Functional neuroimaging techniques now enable us to better understand their pathophysiology and to consider new rehabilitation techniques. Phantom limbs have often been a source of inspiration to writers, particularly in the period following the First World War, which was responsible for thousands of amputees. Some artists have suffered from postamputation complications themselves and have expressed them through their artistic works. Blaise Cendrars (1887-1961), one of the greatest authors of the twentieth century, suffered from stump pain and phantom limb phenomena for almost half a century following the amputation of his right arm during the First World War. He suffered from these phenomena until the end of his life and his literary work and personal correspondence are peppered with references to them. Arthur Rimbaud (1854-1891), one of the most famous poets in world literature, developed severe stump pain after his right leg was amputated due to a tumor. He survived for only six months after the procedure but left behind an account of the pain he experienced in correspondence to his family. The famous pianist Paul Wittgenstein (1887-1961), whose right arm was amputated during the First World War, became a famous left-handed concert pianist. The phantom movements of his right hand helped him to develop the dexterity of his left hand. The impact on the artistic life of these three men provides an original illustration of the various postamputation complications, specifically phantom limbs, stump pain, and moving phantom.

Among his great contributions, he demonstrated that endothelium modulates vasomotor response to vasoactive products (including serotonin) that are released when platelets aggregate in an artery. He found in arteries ex vivo that when endothelium is dysfunctional, in atherosclerosis or hypertension, normal relaxation to aggregation of platelets is impaired, and vessels may contract. He proposed that this mechanism may predispose to vasospasm. Our experiments in vivo indicated that atherosclerosis greatly potentiates vasoconstrictor responses to serotonin in the limb, brain, and eye of monkeys. We proposed that transient ischemic attacks may be mediated by platelet-induced vasospasm. We observed endothelial dysfunction in atherosclerotic monkeys, with improvement of endothelial function when hypercholesterolemia was corrected. Recently, we have studied the aortic valve (which has unique endothelium) in hypercholesterolemic mice, to examine the pathophysiology of aortic valvular stenosis. Oxidative stress is increased in stenotic valves, and severe aortic stenosis develops in about one-third of old, hypercholesterolemic mice. In stenotic aortic valves from humans, there is increased oxidative stress near calcified regions of the valves. Oxidative stress may trigger expression of pro-calcific genes in the aortic valve. Finally, we have used gene transfer of extracellular superoxide dismutase (ecSOD) to study endothelial effects of oxidative stress. Gene transfer of normal ecSOD improves endothelial dysfunction in several disease states, but gene transfer of ecSODR213G, a gene variant of ecSOD that is common in humans, fails to improve endothelial function. Gene transfer approaches may be useful to study mechanisms by which gene variants predispose to endothelial dysfunction and vascular disease. PMID:19033817

  13. The CEO as organizational architect: an interview with Xerox's Paul Allaire. Interview by Robert Howard.

    Allaire, P

    1992-01-01

    As chairman and CEO of the Xerox Corporation, Paul Allaire leads a company that is a microcosm of the changes transforming American business. With the introduction of the first plain-paper copier in 1959, Xerox invented a new industry and launched itself on a decade of spectacular growth. But easy growth led Xerox to neglect the fundamentals of its core business, leaving the company vulnerable to low-cost Japanese competition. Starting in the mid-1980s, Xerox embarked on a long-term effort to regain its dominant position in world copier markets and to create a new platform for future growth. Thanks to the company's Leadership through Quality program, Xerox became the first major U.S. company to win back market share from the Japanese. Allaire describes his efforts to take Xerox's corporate transformation to a new level. Since becoming CEO in 1990, he has repositioned Xerox as "the document company" at the intersection of the worlds of paper-based and electronic information. And he has guided the company through a fundamental redesign of what he calls the "organizational architecture" of Xerox's document processing business. Few CEOs have approached the process of organizational redesign as systematically and methodically as Allaire has. He has created a new corporate structure that balances independent business divisions with integrated R&D and customer operations organizations. He has redefined managerial roles and responsibilities, changed the way managers are selected and compensated, and renewed the company's senior management ranks. And he has articulated the new values and behaviors Xerox managers will need to thrive in a more competitive and fast-changing business environment. PMID:10121313

  14. Grundsätze über die Anlagen neuer Sternwarten mit Beziehung auf die Sternwarte der Universität Göttingen. Von Georg Heinrich Borheck

    Beuermann, Klaus; Borheck, Georg Heinrich

    Die Göttinger Sternwarte, Wirkungsstätte des berühmten Gelehrten Carl Friedrich Gauß, ist ein bedeutendes Baudenkmal. Im Jahre 2005 wird sie gemeinsam von der Georg-August-Universität und der Akademie der Wissenschaften zu Göttingen renoviert, um dann als repräsentatives Gebäude der Universität und Arbeitsstätte der Akademie zu dienen. Die Nutzung der historischen Räume für Ausstellungen macht diesen imposanten Bau erstmals der Öffentlichkeit zugänglich. Die Sternwarte war bei ihrer Errichtung vor 200 Jahren ein nach seinerzeit neuesten wissenschaftlichen Erkenntnissen konzipierter Bau, der die Universität Göttingen in eine der vordersten Stellen Europa rückte. Auch aufgrund ihrer Architektur ist sie ein großer Wurf des Göttinger Universitätsbaumeisters Georg Heinrich Borheck. Durch die Kriegswirren der Napoleonischen Zeit zerschlug sich Borhecks Versuch einer Publikation seiner Beschreibung des Baus der Göttinger Sternwarte 1805. Doch seine Schrift ist auch heute noch aktuell und wird mit diesem Band erstmals einer breiten Öffentlichkeit zugängig gemacht. Er zeigt die Grundsätze, nach denen damals öffentliche Bauten konzipiert wurden, erläutert die Bedeutung des Baus aus kunst- und wissenschaftshistorischer Sicht und informiert über die Pläne zur Restaurierung der Sternwarte in einem separaten Beitrag und im Geleitwort des Präsidenten der Georg-August Universität Prof. Dr. Dr. h. c.

  16. Paul Tsongas and the battles over energy and the environment, 1974--1980

    NASA Astrophysics Data System (ADS)

    Netherton, Dane Morris

    This dissertation examines the political career of Paul Tsongas of Lowell, Massachusetts, from 1974 to 1980, with particular attention to his efforts to reconcile regional, environmental, and economic interests during his two terms in the U.S. House of Representatives and his first two years in the U.S. Senate. The national debates over energy policy during the late 1970s present an essential context for understanding Tsongas's lasting place in American political history. The energy crisis created a divisive legislative battleground during the late 1970s, forming the backdrop of Tsongas's first congressional election in 1974 and his two terms as U.S. Representative. Tsongas played an active part in congressional consideration of energy issues through his seat in the House Committee on Interior and Insular Affairs, his participation in the Ad Hoc Committee (created to shepherd President Jimmy Carter's National Energy Plan through the House of Representatives), and his efforts to locate a Solar Energy Research Center in Massachusetts. Energy issues also formed a backdrop to Tsongas's other accomplishments as a Representative: his key role in the creation of the Lowell National Historical Park, the economic revitalization of Greater Lowell, and the first congressional hearings to examine the contribution of carbon dioxide to global warming. Throughout his career, he worked to promote a rational and responsible regional energy policy for Massachusetts and New England. In his first two years in the Senate, energy issues were intimately connected to Tsongas's role in the Chrysler Bailout bill, the Solar Energy and Energy Conservation Bank Act of 1980, and the Alaska National Interest Lands Conservation Act. Notably, he also worked hard to push President Carter towards a renewed effort to deal with energy problems. This dissertation draws upon the extensive primary sources available in the Tsongas Collections at The University of Massachusetts Lowell's Center for Lowell

    In this special issue, the seminal contributions to clinical psychology of Paul E. Meehl, who passed away in 2003, are commemorated. The nine articles comprising this special issue chronicle Meehl's remarkable intellectual biography and examine his influence on diverse domains of psychology, including the clinical versus actuarial prediction debate, the cognitive activity of the clinician, personality assessment and trait theory, the etiology of schizophrenia, the shortcomings of statistical significance testing, and the use of metascientific methods to evaluate competing models of human nature. These articles illustrate not only Meehl's legendary brilliance but also his pivotal role in forcing clinical psychologists to think more clearly and incisively about their subject matter.

    1981-01-01

    A lightweight, quick starting reactor utilizes a highly active and physically durable methanation catalyst composed of ruthenium on alumina. The use of this improved catalyst permits a single straight through plug flow design with an average lean component H2/CO2 conversion efficiency of over 99% over a range of H2/CO2 molar ratios of 1.8 to 5 while operating with flows equivalent to a crew size of one person steadystate to 3 persons cyclical. The reactor requires no heater operation after start-up even during simulated 55 minute lightside/39 minute darkside orbital operation over the above range of molar ratios and crew loadings. Subsystem performance was proven by parametric testing and endurance testing over a wide range of crew sizes and metabolic loadings. The subsystem's operation and performance is controlled by a microprocessor and displayed on a nineteen inch multi-colored cathode ray tube.

    We have reported evidence for linkage of a region of chromosome 18 markers to affective illness in 22 bipolar (BP) pedigrees. The pedigree series included 21 US pedigrees collected by us and part of Amish pedigree 884 referred to as panel 3 in the catalog and also known as {open_quotes}the right extension.{close_quotes} The rest of 884 was never genotyped by us, because it did not fit the criteria for inclusion, as described elsewhere. Pauls et al. have recently studied whether this linkage can be detected in the entire catalogued Amish pedigrees (884 and 1075) in four of the marker loci reported. The authors conclude that the Amish data contain no significant susceptibility locus for BP illness in this region of chromosome 18. We find that the data published by Pauls et al. are not conclusive with regard to the presence or absence of any susceptibility locus under the nonparametric analyses presented, and, although the sample size is extremely small, it could also be interpreted as consistent with our findings. 17 refs., 1 tab.

    Université de Montréal implemented an interprofessional education (IPE) curriculum on collaborative practice in a large cohort of students (>1,100) from 10 health sciences and psychosocial sciences training programs. It is made up of three one-credit undergraduate courses (CSS1900, CSS2900, CSS3900) spanning the first 3 years of training. The course content and activities aim for development of the six competency domains identified by the Canadian Interprofessional Health Collaborative. This paper describes the IPE curriculum and highlights the features contributing to its success and originality. Among main success key factors were: administrative cooperation among participating faculties, educators eager to develop innovative approaches, extensive use of clinical situations conducive to knowledge and skill application, strong logistic support, close cooperation with health care delivery organizations, and partnership between clinicians and patients. A distinguishing feature of this IPE curriculum is the concept of partnership in care between the patient and caregivers. Patients' representatives were involved in course planning, and patients were trained to become patients-as-trainers and cofacilitate interprofessional discussion workshops. They give feedback to students regarding integration and application of the patient partnership concept from a patient's point of view. PMID:24326925

    Planetary Sciences teach us how special our homeplanet is in the solar system. Incorporating a broad variety of natural science topics they count to the most fundamental branches of scientific research with a strong interdisciplinary character. However, since planetary sciences are not a school subject, children as well as adults are often lacking an overall awareness and understanding of that field. The mission of planetary education has to be fulfilled by research institutions. With several platforms and activities our group is engaged to address this topic. The Planetary Sciences and Remote Sensing Group at Freie Universität Berlin (FUB) is involved in space missions such as Mars Express with the High Resolution Stereo Camera (HRSC), Cassini to Saturn, and Dawn to the asteroids Vesta and Ceres. Moreover, we participate in developing a planetary X-ray fluorescence spectrometer. Information of our planetary research activities can be found on our institutes website [1]. Our outreach activities include press releases, an image download hub, permanent and special exhibition support, 3D-HD-animation production, science fairs, workshops, hands-on courses, public talks at observatories and schools, as well as media appearances in radio, press and TV.

    We used wooden blocks to estimate the proportion of oiled seabird carcasses that were likely to be recovered on beaches of St Paul Island, Alaska following a near-shore oil spill. We released a total of 302 blocks 6 km north of the island in 1997 at the site of a 17 II 1996 oil spill. We used a paired design and released half the blocks when the winds were onshore and released the second half when the winds were offshore. We systematically searched beaches after the second release to recover blocks. We recovered 93 of 152 (61%) blocks released when winds were onshore but only 1 of 150 (0.7%) blocks released when winds were offshore. Given that winds following the 1996 spill were offshore, we conclude that most birds killed at sea following the 1996 spill were likely not recovered on beaches.

    Carlos Ribeiro, one of the directors of the Geological Commission of Portugal, voyaged in 1858 to many countries of Europe to acquire publications, equipment and comparator collections. In Paris he met Paul Deshayes, a well-known conchologist, who gave him access to his personal collections of Tertiary deposits from France and helped him to classify Portuguese fossils. The outcome of the joint work can be seen in the Ribeiro List, which is preserved in the historic archives of the National Energy and Geology Laboratory (Alfragide, Portugal). These classifications served as a basis for a monograph published by Pereira da Costa, Ribeiro's colleague on the Geological Commission, and the definition of the stratigraphy of Portugal's Tertiary deposits.

    The 150th anniversary affords an opportunity to revisit the circumstances surrounding Paul Broca's case report celebrated today as the moment of discovery of aphasia. The proceedings from January to June 1861 of the Paris Society of Anthropology are examined to reconstruct the events surrounding the report of M. Leborgne on April 18th. From a close reading of the presentations and discussions which took place during this period it is apparent that Broca's case report was a minor diversion to a debate about cranial measurements and their relation to intelligence in individuals and racial groups. Moreover, it appears that little attention was granted to Broca's first case at the time. While his ideas about localization and specialization developed and change over the next decade, it represented a minor field of interest for him. Nevertheless Broca's work on aphasia inspired research throughout Europe and North America and went on to have a lasting impact on both aphasiology and neuropsychology. PMID:21831369

    In this article, we review how two eminent Viennese system thinkers, Paul A Weiss and Ludwig von Bertalanffy, began to develop their own perspectives toward a system theory of life in the 1920s. Their work is especially rooted in experimental biology as performed at the Biologische Versuchsanstalt, as well as in philosophy, and they converge in basic concepts. We underline the conceptual connections of their thinking, among them the organism as an organized system, hierarchical organization, and primary activity. With their system thinking, both biologists shared a strong desire to overcome what they viewed as a “mechanistic” approach in biology. Their interpretations are relevant to the renaissance of system thinking in biology—“systems biology.” Unless otherwise noted, all translations are our own. PMID:18217527

    Voter studies conducted in the United States during the first decades after World War II transformed social scientific research on democracy. Especially important were the rapid innovations in survey research methods developed by two prominent research centers at Columbia University and the University of Michigan. This article argues that the Columbia and Michigan voter studies presented two visions for research on democracy. Where the Michigan research produced quantitative measures expressing the 'political behavior' of the electorate, the Columbia studies, and especially Paul F. Lazarsfeld, presented an alternative vision for qualitative research on political choice. Largely ignored by later voter studies, this vision prefigured much contemporary research on democracy that embraces a qualitative or interpretive approach. This article reconstructs Lazarsfeld's alternative vision, describes the institutional context in which scholars disregarded it in favor of formal quantitative models, and argues for its recognition as a forerunner to qualitative research on democratic processes.

  11. An Automatic Unpacking Method for Computer Virus Effective in the Virus Filter Based on Paul Graham's Bayesian Theorem

    NASA Astrophysics Data System (ADS)

    Zhang, Dengfeng; Nakaya, Naoshi; Koui, Yuuji; Yoshida, Hitoaki

    Recently, the appearance frequency of computer virus variants has increased. Updates to virus information using the normal pattern matching method are increasingly unable to keep up with the speed at which viruses occur, since it takes time to extract the characteristic patterns for each virus. Therefore, a rapid, automatic virus detection algorithm using static code analysis is necessary. However, recent computer viruses are almost always compressed and obfuscated. It is difficult to determine the characteristics of the binary code from the obfuscated computer viruses. Therefore, this paper proposes a method that unpacks compressed computer viruses automatically independent of the compression format. The proposed method unpacks the common compression formats accurately 80% of the time, while unknown compression formats can also be unpacked. The proposed method is effective against unknown viruses by combining it with the existing known virus detection system like Paul Graham's Bayesian Virus Filter etc.

    The MUSE experiment in the PIM1 Channel at the Paul Sherrer Institute in Villigen, Switzerland, measures scattering of electrons and muons from a liquid hydrogen target. The intent of the experiment is to deduce from the scattering probabilities whether the radius of the proton is the same when determined from the scattering of the two different particle types. An important technique for the experiment is precise timing measurements, using high precision scintillators and a beam Cerenkov counter. We will describe the motivations for the precise timing measurement. We will present results for the timing measurements from prototype experimental detectors. We will also present results from a simulation program, Geant4, that was used to calculate energy loss corrections to the time of flight determined between the beam Cherenkov counter and the scintillator.

    Eleven expeditions were undertaken to the Saint Peter and Saint Paul Archipelago to study the reproductive biology of Grapsus grapsus, providing additional information on limb mutilation and carapace colour. MATURE software was used to estimate morphological maturity, while gonadal analyses were conducted to estimate physiological maturity. The puberty moult took place at larger size in males (51.4 mm of carapace length) than in females (33.8 mm), while physiological maturity occurred at a similar size in males (38.4 mm) and in females (33.4 mm). Above 50 mm, the proportion of red males increased in the population, indicating that functional maturity is also related to colour pattern. Small habitat and high local population density contributed to the high rate of cannibalism. The low diversity of food items, absence of predators of large crabs and high geographic isolation are the determinants of unique behavioural and biological characteristics observed in the G. grapsus population.

    Sponges are one of the most complex symbiotic communities and while the taxonomic composition of associated microbes has been determined, the biggest challenge now is to uncover their functional role in symbiosis. We investigated the microbiota of two widely distributed sponge species, regarding both their taxonomic composition and their functional roles. Samples of Didiscus oxeata and Scopalina ruetzleri were collected in the oceanic archipelago of St Peter and St Paul and analysed through metagenomics. Sequences generated by 454 pyrosequencing and Ion Torrent were taxonomically and functionally annotated on the MG-RAST server using the GenBank and SEED databases, respectively. Both communities exhibit equivalence in core functions, interestingly played by the most abundant taxa in each community. Conversely, the microbial communities differ in composition, taxonomic diversity and potential metabolic strategies. Functional annotation indirectly suggests differences in preferential pathways of carbon, nitrogen and sulphur metabolisms, which may indicate different metabolic strategies. PMID:25873456

    The Saint Peter and Saint Paul Archipelago in the central tropical Atlantic, is an important ground of whale sharks that are commonly sighted throughout the year close to the fishing boats in the adjacencies of the islands. In sightings reported between February 2000 and November 2005, the lengths of the individuals ranged between 1.8 to 14.0 m. The causes of these concentrations in the archipelago are still unclear, once there are no upwellings and plankton concentrations for feeding, and no reproductive activities were reported. Nevertheless, they could be associated to the spawning period of the abundant flying fishes, mainly in the first semester, when sightings were more frequent. PMID:18660968

    The pressure–temperature phase diagram of ice displays a perplexing variety of structurally distinct phases. In the century-long history of scientific research on ice, the proton-ordered ice phases numbered XIII through XV were discovered only recently. Despite considerable effort, none of the transitions leading from the low-temperature ordered ices VIII, IX, XI, XIII, XIV and XV to their high-temperature disordered counterparts were experimentally found to display the full Pauling entropy. Here we report calorimetric measurements on suitably high-pressure-treated, hydrogen chloride-doped ice XIV that demonstrate just this at the transition to ice XII. Dielectric spectroscopy on undoped and on variously doped ice XII crystals reveals that addition of hydrogen chloride, the agent triggering complete proton order in ice XIV, enhances the precursor dynamics strongest. These discoveries provide new insights into the puzzling observation that different dopants trigger the formation of different proton-ordered ice phases. PMID:26076946

To this end, it contrasts what Saint John Paul II calls an individualistic understanding of freedom and a personalistic notion of the same in order to argue that human freedom is called by the Creator to be in service of, and not in opposition to, the good of the human family. From this perspective—that of the social doctrine of the Catholic Church—it argues for the harmony between natural marriage and the respect of fundamental human rights, and it presents the social dimension of marriage as fundamental with respect to the legal and social protection of the family.

    PubMed

    2001-08-01

    Existentialism and phenomenology are closely linked philosophies. Existentialism preceded phenomenology and is not considered a single philosophy but several schools of thought, both theist and atheist in thinking, which grew out of a reaction to traditional philosophy. The development of phenomenology is divided into three separate phases ultimately merging with existentialism. Following Second World War, the phenomenological movement gained momentum in France and encompassed many of the ideas of Edmund Husserl and Martin Heidegger. Gabriel Marcel, Maurice Merlieu-Ponty and, notably, Jean-Paul Sartre established a 'third phase' of phenomenology. This paper explores some of Sartre's ideas related to being and later applications through Medard Boss and R.D. Laing, and offers a short illustrative case vignette that shows the concepts as they might apply to nursing practice. Consideration is finally given to existential psychoanalysis as an applied research methodology PMID:11882149

  9. Evidence for fractionation of Quaternary basalts on St. Paul Island, Alaska, with implications for the development of shallow magma chambers beneath Bering Sea volcanoes

    NASA Astrophysics Data System (ADS)

    Feeley, T. C.; Winer, G. S.

    1999-04-01

    St. Paul Island is the youngest volcanic center in the Bearing Sea basalt province. We have undertaken a field, petrographic, and geochemical study of select St. Paul volcanic rocks in order to better understand their differentiation; specifically, to test the hypothesis that magmas erupted from individual Bering Sea basaltic volcanoes are not related by shallow-level processes such as crystal fractionation. Petrographically, all of the St. Paul volcanic rocks are olivine-, plagioclase-, and clinopyroxene-phyric. Textural features and modal contents of olivine phenocrysts, however, vary widely throughout the spectrum of basalt compositions. Although differing in size and abundance, olivine phenocrysts in all rock compositions are euhedral and commonly skeletal, suggesting rapid growth during ascent or eruptive quenching. None, however, display reaction textures with surrounding groundmass liquid. Compositionally, the St. Paul volcanic rocks are basalts and tephritic basalts and all have high contents of normative nepheline (8% to 16%). Concentrations of many major and incompatible trace elements display no clear correlations with bulk-rock SiO 2 and MgO contents or modal abundances of phenocrysts, suggesting that much of the compositional diversity of these magmas reflects variable mantle sources and degrees of partial melting. Similarly, chondrite-normalized REE patterns show variable degrees of light REE enrichment (La n=70-90) that do not correlate with bulk-rock mg-numbers. In contrast, concentrations of compatible trace elements (Ni, Cr, and Co) are positively correlated with MgO contents and modal percentages of olivine phenocrysts. Maximum forsterite contents of olivine phenocryst cores in most St. Paul rocks decrease with decreasing bulk-rock mg-number and are similar to the calculated equilibrium range. This is evidence that the high mg-numbers are magmatic and do not result from olivine accumulation. Instead, major and compatible trace element mass

    Episodes of phreatomagmatic explosive activity that excavate large deep craters occur at high-elevation vents on many oceanic island volcanoes. The water driving these explosions is sourced from freshwater aquifers within the volcanic edifices, whose location and other characteristics will influence crater growth and final geometry. Here we describe phreatomagmatic deposits from the single eruption that formed the large Cova de Paul crater on the island of Santo Antao, Cape Verde Islands. These deposits, emplaced after an initial Strombolian phase of activity, record wide fluctuations in the intensity of phreatomagmatic explosivity. The largest explosions produced low-temperature, indurated lithic-rich phreatomagmatic ignimbrites and surge deposits; these occur as isolated and often erosive-based units in more distal areas but are interbedded in proximal outcrops with airfall to mixed fall and flow breccia and ash beds containing varying proportions of lithic and juvenile clasts, pointing to a series of climactic explosions within an extended period of milder phreatomagmatic explosive activity. We find that whereas the lithic clasts in the mixed units can be matched with the varied rock units in the exposed crater walls, the ignimbrite and surge units also contain hydrothermally altered clasts that appear to have originated from deeper in the volcanic edifice. They imply that during the climactic explosions the crater was excavated to several hundred meters depth below the surface. The phreatomagmatic explosive phase of the CDPC eruption was initiated by shattering of the chilled margins of the eruptive conduit, which had formed during the early Strombolian activity. The remains of these chilled margins form a distinctive bed of large flow-banded angular sub-glassy juvenile clasts that separates the Strombolian deposits from the later phreatomagmatic deposits. At this point water inflow from pressurized aquifers into the conduit attained a critical coolant input

    Isolated oceanic islands constitute interesting model systems for the study of colonization processes, as several climatic and oceanographic phenomena have played an important role in the history of the marine ichthyofauna. The present study describes the presence of two morphotypes of Caranx lugubris, in the St. Peter and St. Paul Archipelago located in the mid-Atlantic. Morphotypes were compared in regard to their morphological and cytogenetic patterns, using C-banding, Ag-NORs, staining with CMA3/DAPI fluorochromes and chromosome mapping by dual-color FISH analysis with 5S rDNA and 18S rDNA probes. We found differences in chromosome patterns and marked divergence in body patterns which suggest that different populations of the Atlantic or other provinces can be found in the Archipelago of St. Peter and St. Paul.

    On the centenary of Paul Ehrlich's Nobel Prize, this German researcher deserves to be remembered as a pioneer in a large number of scientific disciplines. As a result of his enthusiasm and scientific abilities, dedication, and contacts with other scientists of his time, he was able to make countless contributions in fields as diverse as histology, haematology, immunology, oncology, microbiology and pharmacology, among others. Although the Swedish award was meant to recognize the standardization of the manufacture of antidiphtheria serum, it was the discovery of arsphenamine (Salvarsan) for the treatment of syphilis which won him wider international acclaim. From a pharmacological perspective, Ehrlich's outstanding contributions include dissemination of the 'magic bullet' concept for the synthesis of antibacterials, introduction of concepts such as chemoreceptor and chemotherapy, and linking the chemical structure of compounds to their pharmacological activity. These achievements took place within the framework he established for the transition from experimental pharmacology to therapeutic pharmacology. He introduced a modern research system based on the synthesis of multiple chemical structures for pharmacological screening in animal models of disease states. These contributions were undoubtedly decisive in propitiating the wider development of antibiotics decades later. For these reasons, it is fitting to mark the 100th anniversary of the Nobel Prize awarded to this great scientist by commemorating the importance of his contributions to the advance of pharmacology.

    Mesophotic reef fish assemblages (30-90 m depth) of the small and remote St. Peter and St. Paul's Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil, were characterized using remotely operated vehicles. Ordination analyses identified distinct fish assemblages in the upper (30-50 m) and lower (50-90 m) mesophotic zones, the former characterized by high abundances of species that are also abundant at euphotic reefs ( Caranx lugubris, Melichthys niger, Stegastes sanctipauli and Chromis multilineata) and the latter dominated by two mesophotic specialists ( Prognathodes obliquus and Chromis enchrysura). Planktivores dominated fish assemblages, particularly in the upper mesophotic zone, possibly due to a greater availability of zooplankton coming from the colder Equatorial Undercurrent in mesophotic depths of the SPSPA. Turf algae, fleshy macroalgae and scleractinian corals dominated benthic assemblages between 30 and 40 m depth, while bryozoans, black corals and sponges dominated between 40 and 90 m depth. Canonical correspondence analysis explained 74 % of the relationship between environmental characteristics (depth, benthic cover and complexity) and structure of fish assemblages, with depth as the most important independent variable. Juveniles of Bodianus insularis and adults of P. obliquus and C. enchrysura were clearly associated with branching black corals ( Tanacetipathes spp.), suggesting that black corals play key ecological roles in lower mesophotic reefs of the SPSPA. Results from this study add to the global database about mesophotic reef ecosystems (MREs) and provide a baseline for future evaluations of possible anthropogenic and natural disturbances on MREs of the SPSPA.

    The Surrounding Field Compensation (SFC) system described in this work is installed around the four-layer Mu-metal magnetic shield of the neutron electric dipole moment spectrometer located at the Paul Scherrer Institute. The SFC system reduces the DC component of the external magnetic field by a factor of about 20. Within a control volume of approximately 2.5 m × 2.5 m × 3 m, disturbances of the magnetic field are attenuated by factors of 5–50 at a bandwidth from 10{sup −3} Hz up to 0.5 Hz, which corresponds to integration times longer than several hundreds of seconds and represent the important timescale for the neutron electric dipole moment measurement. These shielding factors apply to random environmental noise from arbitrary sources. This is achieved via a proportional-integral feedback stabilization system that includes a regularized pseudoinverse matrix of proportionality factors which correlates magnetic field changes at all sensor positions to current changes in the SFC coils.

    In conformity with Regulation (EC) No. 1394/2007, advanced therapy medicinal products (ATMP) are now subject to the centralized marketing authorization procedure. This also applies to most medicinal products in regenerative medicine. ATMP that have been marketed in a member state by the end of 2008 must be centrally authorized by the end of 2012 at the latest. In exceptional cases, a national authorization is acceptable. Developers of these medicinal products are usually academic institutions or small- and medium-sized enterprises (SME). They focus on scientific aspects and usually have little experience with pharmaceutical law. The Innovation Office of the Paul-Ehrlich-Institut (PEI) is designed to support developers of medicinal products in the areas between research and development, on the one hand, and regulatory requirements, on the other. Its main role is supportive advice in the regulatory field with an emphasis on ATMP. For this purpose, the Innovation Office makes use of core competences from various experts at the PEI in order to provide a quality consulting service to those companies who are seeking advice as early as possible and hand in hand with the development process. The aim is to support the developer to identify the appropriate regulatory pathway and to provide advice for each individual medicinal product at its corresponding stage of development in order to develop a high-quality ATMP manufactured on the basis of positive nonclinical results and appropriate clinical studies that meet all the necessary requirements for the application of a marketing authorization.

    Jean-Paul Marat was a French revolutionary, famously murdered in his bath by Charlotte Corday in 1793. A lesser known fact is that for over ten years he lived in Britain where he practised as a doctor. During this time he visited London, Edinburgh, Dublin and Holland. Although he had no formal medical training, he published two medical papers on gleets (gonorrhoea) and diseases of the eyes and, on the recommendation of two eminent Scottish physicians, William Buchan and Hugh James, he was granted a medical degree from the University of St Andrews. Marat left no medical legacy and his related writings were forgotten for 100 years until the rediscovery of the two medical papers, which were eventually re-published in 1892 at the instigation of James Bailey, the librarian of the Royal College of Surgeons of England. Biographies by F Chevremont (1880), Ashbee Spencer (1890) and A Cabanès (1891) had rekindled interest in this intriguing revolutionary. A study of his time in Britain and his medical works and training provide an interesting insight into the mind of a revolutionary and how his sojourn may have shaped his future political career upon his return to France in 1777.

    Reports of postamputation pain and problems linked to phantom limbs have increased in recent years, particularly in relation to war-related amputations. These problems are still poorly understood and are considered rather mysterious, and they are difficult to treat. In addition, they may shed light on brain physiology and neuropsychology. Functional neuroimaging techniques now enable us to better understand their pathophysiology and to consider new rehabilitation techniques. Several artists have suffered from postamputation complications and this has influenced not only their personal life but also their artistic work. Paul Wittgenstein (1887-1961), a pianist whose right arm was amputated during the First World War, became a famous left-handed concert performer. His case provides insight into Post-World War I musical and political history. More specifically, the impact on the artistic life of this pianist illustrates various postamputation complications, such as phantom limb, stump pain, and especially moving phantom. The phantom movements of his right hand helped him develop the dexterity of his left hand. Wittgenstein played piano works that were written especially for him (the most famous being Ravel's Concerto for the Left Hand) and composed some of his own. Additionally, several famous composers had previously written for the left hand. PMID:25684295

    A numerical simulation has been constructed that illustrates the vertical biological pathways of carbon fluxes from the surface down through the entire water column to the Sigsbee Abyssal Plain at a depth of 3.7 km in the central Gulf of Mexico (GoM). Seasonal production of particulate organic carbon (POC) in a six month long pulse is delivered with lag times that reflect sinking rates of the POC and time-dependent incorporation of the POC into biomass by the pelagic and the benthic biota. The model illustrates that the seasonal variations in carbon and energy are transmitted down the water column and, in the model, are reflected in subdued but distinct variations in pelagic and benthic respiration and biomass; the amount reaching the bottom is adequate to support the variable growth patterns of numerous shell-bearing invertebrates on the deep-sea floor described by Paul Tyler and John Gage. A notable realization is the profound lack of information on the biomass and bioenergetics of the deep abyssopelagic biota in the GoM.

    This paper presents an interview with Dr Paul W. Kruse (1927-2012) on the early history of the semiconductor alloy mercury cadmium telluride (HgCdTe or Hg1- x Cd x Te) at the Honeywell Corporate Research Center near Minneapolis, Minnesota. Conducted on October 22, 1980, the interview covers two main areas. One area is the story of how the HgCdTe research effort came about at the Honeywell Research Center in the early 1960s, what technical choices were made and when, and what technical challenges were overcome and how. The other area is the organization, culture, environment and personnel at the Honeywell Research Center that made the early HgCdTe research programs so successful. HgCdTe has emerged as the highest-performance, most widely applicable infrared detector material. HgCdTe continues to satisfy a broad variety of advanced military and space applications. It is illustrative to look back on the early history of this remarkable semiconductor alloy to help to understand why its technological development as an infrared detector has been so successful.

    Jean-Martin Charcot (1825-1893) was the one of the world's leading physicians during the final third of the 19th century. Rewarded in 1882 with the creation of the first chair in the diseases of the nervous system, he was extremely successful at recruiting loyal and talented students. Charcot himself never produced a general treatise on hysteria, but instead encouraged his pupils to write their own books. Here, we describe how the work on hysteria of Georges Gilles de la Tourette, Paul Richer, Charles Féré and Alfred Binet was closely associated with Charcot, and how they remained faithful to their mentor. We will highlight the unusual personality of G. Gilles de la Tourette and the tragic end to his life, the exceptional artistic talent of P. Richer (writer and painter of his magnificently illustrated thesis), the prolific writing capacity of C. Féré (bearing witness to his broad fields of interest) and A. Binet (blessed with an extraordinary capacity for work, and author of The Psychology of Reasoning, before presenting his metric scale of intelligence). PMID:20938148

    Electron beam ion traps used for spectroscopy of highly charged ions (HCI) produce a deep trapping potential leading to high temperatures of the stored ions, and thus limiting the achievable spectral resolution. A novel device at the Max-Planck-Institut für Kernphysik, the Cryogenic linear Paul Trap Experiment (CryPTEx), attached to an electron beam ion trap, provides a new experimental platform to overcome these limitations. The trap assembly operates at a temperature of 4 K and offers optical access for quantum manipulation and imaging of the trapped ions. Since forbidden optical transitions in HCI do not support direct laser cooling, sympathetic cooling with Coulomb crystals of singly charged ions such as Be+ or Mg+ will be applied in order to reach the natural linewidth of optical forbidden transitions in HCI of interest. With the added advantage of long ion trapping times resulting from residual gas pressures of H2 at 4 K below 10-15 mbar, CryPTEx has been commissioned in collaboration with the Ion Trap Group in Århus using rovibrationally cooled MgH+ ions. Strong suppression of the black body radiation at the trap center, ion storage times of about 28 hours, and largely enhanced population of the rovibrational ground state were achieved.

    A great blue heron (Ardea herodias) colony on Pig's Eye Island on the Mississippi River near St. Paul, Minnesota, USA, is located near several potential perfluorinated compound (PFC) sources. The PFC concentrations in great blue heron eggs reported from a 1993 collection from the Pig's Eye colony were among the highest measured in bird eggs worldwide. The objective of this investigation was to determine whether PFC concentrations in great blue heron eggs at the Pig's Eye colony have changed since 1993. Total PFC concentrations in great blue heron eggs collected at the Pig's Eye colony in 2010 and 2011 (geometric mean=340 and 492 ng/g wet wt) were 60% lower than the 1993 collection (1,015 ng/g wet wt). Among PFCs, perfluoroalkyl sulfonate concentrations were lower and perfluoroalkyl carboxylate concentrations were higher in the 2010 and 2011 collections. Two of 20 (10%) of the eggs analyzed from Pig's Eye in 2010 and 2011 were >1,000 ng PFCs/g wet weight and the maximum PFC value (2,506 ng PFCs/g wet wt) measured in 2010 and 2011 was among the highest PFC concentration reported in bird eggs. These high concentrations are at levels associated with physiological and neurological effects in birds. PMID:23378367

    Ground-water baseflow to six subreaches of the Upper Mississippi River were estimated for July 1988, a period of drought. Ground-water baseflow to each subreach was estimated on the basis of streamflow gains determined from records of daily discharge at gaging stations. Streamflow gains were adjusted for estimated inflow from tributaries, municipal and industrial discharges, withdrawals, and evaporation. Low-flow frequency characteristics were computed for the Mississippi River near Anoka, Minnesota and the Mississippi River at St. Paul, Minnesota.

This system has been carried since 1990 on the French SPOT 2 satellite, since 1992 on the French/American satellite TOPEX/POSEIDON, and since 1998 on the French SPOT 4 satellite. It will be part of the JASON (CNES/NASA) and ENVISAT (ESA) altimetric missions and also the SPOT follow-on Earth observation missions. DORIS is a radio-electrical system which takes Doppler measurements between a satellite in low orbit and a permanent global network for the purpose, on the one hand, of determining the satellite's position in orbit, and on the other hand, of locating ground beacons with a high degree of precision.

    Doing violence and evil always indirectly or directly leads to making someone else suffer. Such is the dialogical structure of evil and it seems to be the dialogical structure of elder abuse as well. There is a perturbing sameness between definitions of evil and definitions of elder abuse. It is hard at times to see how or if there is any line of demarcation between the subjects. Two modern-day philosophers, Paul Ricoeur and Simone Weil have delved particularly into the concept of evil. The symbolism Ricoeur analyses in depth is that of defilement, sin, and guilt and the concept of the servile will. Integral in Weil's description of evil are the concepts of suffering and the special situation of extreme suffering, termed affliction. Grounded in the writings of Ricoeur and Weil, this paper is a series of reflections on the intersection of evil and elder abuse as exemplified in the narrative of an abused older woman. This woman provided around the clock care at home for her husband who had vascular dementia. She was also abused by her husband. This was witnessed by both family and others but no one intervened. In her narrative there were indications of defilement, sin, guilt, and true affliction as a servile will. This paper illuminates the evil of elder abuse that is harm and suffering, and the challenge of untangling issues of blame, free will, responsibility, and self-determinism. When engaging with abused, older persons it can be worthwhile for nurses to enter the encounter with non-judgemental compassion founded on the human to human connection and recognition of our mutual fallibility and potential for evil that is part of our human fragility.

    To document and quantify subsistence harvests of fish and wildlife resources, and provide topics for subsequent key respondent interviews to collect local and traditional knowledge (LTK) about the Bering Sea ecosystem, comprehensive household harvest surveys were conducted in four Bering Sea Alaska Native communities: Akutan, Emmonak, Savoonga, and Togiak. In a fifth community, St. Paul, annual programs to document two key subsistence resources, fur seals and sea lions, continued. Surveys documented relatively high and diverse subsistence harvests, consistent with earlier research that demonstrated the continuing economic, social, and cultural importance of subsistence uses of wild resources. The research also found differences in subsistence use patterns compared to previous years' studies, such as harvest levels, harvest composition, and diversity of resources used, although differences between study years were not uniform across communities. Survey respondents, as well as key respondents in subsequent interviews, identified a complex range of personal, economic, and environmental factors when comparing subsistence uses in the study year with other years, such as increasing costs of fuel and purchased food, commercial fisheries harvests and bycatch, more persistent storms and less predictable winds, and reduced sea ice. Such conditions affect resource abundance and locations as well as access to fish and wildlife populations, and may shape long-term trends. So far, as in the past, families and communities have adapted to changing economic, social, and environmental conditions, but the future is less clear if such changes intensify or accelerate. Local community residents should be essential partners in future efforts to understand these complex processes that affect the natural resources of the Bering Sea.

    Purpose: Radiotherapy plays a major role in the treatment strategy of childhood sarcomas. Consequences of treatment are likely to affect the survivor's quality of life significantly. We investigated the feasibility of spot-scanning proton therapy (PT) for soft tissue tumors in childhood. Methods and Materials: Sixteen children with soft tissue sarcomas were included. Median age at PT was 3.3 years. In 10 children the tumor histology was embryonal rhabdomyosarcoma. All tumors were located in the head or neck, parameningeal, or paraspinal, or pelvic region. In the majority of children, the tumor was initially unresectable (Intergroup Rhabdomyosarcoma Study [IRS] Group III in 75%). In 50% of children the tumors exceeded 5 cm. Fourteen children had chemotherapy before and during PT. Median total dose of radiotherapy was 50 cobalt Gray equivalent (CGE). All 16 children were treated with spot-scanning proton therapy at the Paul Scherrer Institute, and in 3 children the PT was intensity-modulated (IMPT). Results: After median follow-up of 1.5 years, local control was achieved in 12 children. Four children failed locally, 1 at the border of the radiation field and 3 within the field. All 4 children died of tumor recurrence. All 4 showed unfavorable characteristic either of site or histopathology of the tumor. Acute toxicity was low, with Grade 3 or 4 side effects according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) criteria occurring in the bone marrow only. Conclusions: Proton therapy was feasible and well tolerated. Early local control rates are comparable to those being achieved after conventional radiotherapy. For investigations on late effect, longer follow-up is needed.

    The COLMEIA cruise, held in the Equatorial Atlantic, in the area of the St. Paul transform system, is part of a joint effort between France and Brazil for the study of the Mid-Atlantic ridge near the St. Peter & St. Paul's Rocks. The scientific objective of the cruise was to study in detail the temporal evolution of the complex transform plate boundary, and the origin of the St. Peter-St. Paul mylonitic massif. This area of the Mid-Atlantic ridge was considered to be a mantle 'cold spot', thus a magma-starved region with large occurrences of mantle-derived units outcropping at the seafloor. During the cruise we acquired multibeam echosounder bathymetry, backscattering, water column acoustic data, gravity, magnetics and seismics. 31 dredges successfully returned a wide variety of rocks, including basalts, gabbros and peridotites. The 15 CTD stations with nephelometric profiles casted in the transform region returned a single hydrothermal plume signal, probably sourced in the MAR segment south of the St. Paul system, while no hydrothermal activity was directly detected inside the transform system. 5 autonomous hydrophones were moored in the SOFAR channel around the study area in order to monitor the seismic activity and whale presence; they will be recovered mid-2014. Both bathymetry data and recovered rocks show that the image of a regional amagmatic MAR cannot be applied to the whole of the St. Paul system. The ridge segments are short and narrow, with deep axial valleys. Axial depths are below 4000 m on average, and reach 5400 m in some nodal basins. There is no evidence for a clearly defined neo-volcanic ridge on the axial valley floors, but a few volcanoes were observed in the axial valley of the central segment. The pattern of off-axis abyssal hills is highly variable from one segment to another. The northern segment displays a long sequence of magmatic abyssal hills. The central segment shows both hummocky ridges probably of magmatic origin, alternated to

    The reproduction of Blackfin tuna Thunnus atlanticus has been described for coastal regions, and for a long time, this species was considered to be a strictly continental spawner. Recently, this species was observed around a seamount habitat 500 nautical miles Northeast of Brazil, located between South America and Africa. In this study we describe the reproductive biology of Blackfin tuna at Saint Peter and Saint Paul Archipelago (SPSPA). Male and female gonads were sampled from December 2008 to July 2010, and analyzed macro and microscopically. A total of 361 fish were sampled (247 males and 114 females). Males were more common than females, with a sex ratio of 2.2 male:1 female. The fork length (FL) of all sampled specimens ranged from 38 to 98cm, and larger length classes were more frequent in males. It was possible to distinguish six maturity phases for females: immature, developing, spawning capable, actively spawning, regressing and recovering. Five phases were identified for males: immature, developing, spawning capable, actively spawning and recovering. The gonad index (GI) mean monthly values ranged from 6.6 (SD = 4.1) to 58.4 (SD = 34.7) for females, and from 2.6 (SD = 1.3) to 66.2 (SD = 30.4) for males. For both sexes, the largest GI values were observed at the beginning of the first semester of the year. Size at first maturity was estimated at 48cm FL and 55cm FL for females and males respectively. Approximately 80% of the specimens were adults and considered to be in reproductive conditions. Histological analysis of the ovaries and testes showed that most of the specimens were sexually mature and were reproductively active during all months of the year. However, females with mature ovaries, with large amounts of hydrated oocytes and post-ovulatory follicles, were mainly found from December to March, thus these months may constitute the main spawning season in SPSPA. Batch fecundity varied between 272025 and 1,140584 oocytes for 56 and 68 cm FL females

  17. The Ninetyeast Ridge and its Relation to the Kerguelen, Amsterdam and St. Paul Mantle Plumes in the Indian Ocean

    The Ninetyeast Ridge, a 5000 km long north-south oriented submarine volcanic ridge in the eastern Indian Ocean, has been interpreted to have formed from magmatism associated with the deep-seated Kerguelen mantle plume as the Indian plate drifted rapidly northward during the Late Cretaceous. Samples recovered along the ridge have the characteristic Dupal geochemical signatures of Indian Ocean basalts, but debate concerning the nature and number of components in the mantle source contributing to the formation of these basalts persists. New MC-ICP-MS (Pb, Hf) and TIMS (Sr, Nd) isotopic analyses were determined for tholeiites representative of the ~180 m of basaltic basement recovered from three drill sites (758: 82 Ma; 757: 58 Ma, 756: 43 Ma) along the Ninetyeast Ridge during ODP Leg 121. These analyses provide substantially greater precision compared to earlier studies (ppm vs. % range) after removal of the effects of post-magmatic alteration by thorough acid leaching [1]. No systematic temporal or spatial isotopic variations are observed along the ridge, which is inconsistent with the hypothesis of an aging mantle plume origin for the ridge [2]. The Pb-Hf-Sr-Nd isotopic compositions of the Ninetyeast Ridge basalts are generally intermediate between those of the volcanic products of the Kerguelen and Amsterdam-St. Paul mantle plumes and define mixing trends between components with relatively enriched and depleted signatures. At least three, possibly four, source components are required to explain the observed isotopic variability along the Ninetyeast Ridge. The less radiogenic isotopic signatures of some Ninetyeast Ridge basalts (87Sr/86Sr = 0.70381-0.70438) are not consistent with mixing with shallow level Indian MORB and are instead consistent with the presence of a relatively depleted component in a deep mantle source. A similar source component is also identified in other Indian ocean island basalts (e.g., Crozet, Réunion [3, 4]) with typical EM-1-like

    Purpose To determine the relative biologic effectiveness (RBE) of the Paul Scherrer Institute (PSI) scanning proton beam in reference conditions and to evaluate the influence of intestine motion on the proton dose homogeneity. Methods and Materials: First, RBE was determined for crypt regeneration in mice after irradiation in a single fraction. Irradiation was performed at the middle of a 7-cm spread out Bragg peak (SOBP; reference position), as well as in the proximal part of the plateau and at the distal end of the SOBP. Control {gamma}-irradiation was randomized with proton irradiation and performed simultaneously. Second, motion of mouse intestine was determined by radiographs after copper wire markers had been placed on the jejunum and intestinal wall. Results: Proton RBE (reference {sup 60}Co {gamma}) was equal to 1.16 for irradiation at the middle of the SOBP and to 1.11 and 1.21 for irradiation in the initial plateau and end of the SOBP, respectively. The confidence intervals for these RBE values were much larger than those obtained in the other proton beams we have tested so far. They exceeded {+-}0.20 (compared with the usual value of {+-}0.07), which resulted from the unusually large dispersion of the individual proton data. The instantaneous positions of the mice intestines varied by {+-}2 mm in the course of irradiation. Conclusion: The results of this study have shown that the RBE of the PSI proton beam is in total accordance with the RBE obtained at the other centers. This experiment has corroborated that proton RBE at the middle of the SOBP is slightly larger than the generic value of 1.10 and that there is a slight tendency for the RBE to increase close to the end of the SOBP. Also, excessive dispersion of individual proton data may be considered to result from intestine motion, taking into account that irradiation at the PSI is delivered dynamically by scanning the target volume with a pencil proton beam ('spot scanning').

    Miniaturized chemical instrumentation is needed for in situ measurements in planetary exploration and other spaceflight applications where factors such as reduction in payload requirements and enhanced robustness are important. In response to this need, we are 'continuing to develop miniaturized GC/MS instrumentation which combines chemical separations by gas chromatography (GC) with mass spectrometry (MS) to provide positive identification of chemical compounds in complex mixtures of gases, such as those found in the International Space Station's cabin atmosphere. Our design approach utilizes micro gas chromatography components coupled with either a miniature quadrupole mass spectrometer array (QMSA) or compact, high-resolution Paul ion trap.

  1. USing the probability density function of radar reflectivity to identify precipitation in thunderstorms

    In many studies discussing the statistical characterization of the rain rate, most of the authors have found that the probability density function (PDF) of the rain rate follows a lognormal law. However, a more careful analysis of the PDF of the radar reflectivity Z suggests that it is a question of a mixture of distributions. The purpose of this work is to identify precipitation types that can coexist in a continental thunderstorm from the PDF of the radar reflectivity. The data used come from the NEXRAD S-band radar network, notably the level II database. From reflectivity ranging from -10 dBZ to 70 dBZ, we compute the PDF. We find that the total distribution is a mixture of several populations adjusted by several gaussian distributions with known parameters : mean, standard deviation and proportion of each one in the mixture. Since it is known that the rainfall is a sum of its parts and is composed of hydrometeors of various sizes, these statistical findings are in accordance with the physical properties of the precipitation. Then each component of the mixed distribution is tentatively attributed to a physical character of the precipitation. The first distribution with low reflectivities is assumed to represent the background of the small sized particles. The second component centred around medium Z corresponds to stratiform rain, the third population located at larger Z is due to heavy rain. Eventually a fourth population is present for hail. *Observatoire Midi-Pyrénées, Laboratoire d'Aérologie, CNRS/Université Paul Sabatier, Toulouse , France **Université des Sciences et Technologies de Lille, UFR de Physique Fondamentale, Laboratoire d'Optique Atmosphérique, Lille, France

    Iraq-Iran war resulted in more than 400,000 people requiring prolonged medical care in Iran. An international team of prominent reconstructive surgeons led by Paul Tessier, the founder of craniofacial surgery, was invited to Iran during the war by official organizations entitled to support war victims. This team provided up-to-date oral and maxillofacial rehabilitation to patients with severe trauma defects in the lower third of the face. We collected the medical notes of 43 patients operated on by the Tessier team in Iran in the 1980s (files property of AFCF). The parameters we collected were: age of the patient, nature of the trauma (when available), previous procedures, number of implants placed (mandibular and maxillary), associated procedures (bone grafts, soft-tissue procedures, orthognathic surgery). A protocol based on soft-tissue rehabilitation using local flaps, parietal or iliac bone grafts and implant placement 6 months later was used in all patients. Paul Tessier's approach emphasizes the importance of keeping high standards of care in difficult situations and maintaining standard protocols. PMID:25887424

    Studies of northern fur seal (Callorhinus ursinus Linnaeus, 1758) infection by the filariid nematode Acanthocheilonema odendhali were carried out in 2011-2012 on St. Paul Island, Pribilof Archipelago, Alaska. Skins of 502 humanely harvested northern fur seals from haul-out areas of five rookeries, Polovina (n = 122), Morjovi (n = 54), Zapadni (n = 72), Lukanin (n = 109), and Gorbatch (n = 145), were examined. A. odendhali was found in 18% of northern fur seals. The prevalence of infection ranged from 12.5% up to 22.9% on different haul-out areas on the island. The mean intensity of infection was 1.3 (range 1-7). Detailed morphological examination of collected specimens was performed using light microscopy. Several characters were added to the morphological description of the species, among them lateral thickening of the body cuticle, especially prominent in males, variations in number and position of genital papillae in males, transverse striation of the cuticle, and terminal dilation on tail end in microfilariae. The adult specimens studied had a shorter esophagus than type specimens from the California sea lion described by Perry (1967). Comparison of partial sequences of the mitochondrial cox1 gene from specimens collected from five sampling sites on St. Paul Island and a specimen from the type host and territory in California showed no significant differences and strongly supported conspecificity of the material from Alaska with A. odendhali.

    The Paul Scherrer Institut (PSI) is the largest national research centre in Switzerland. Its multidisciplinary research is dedicated to a wide field in natural science and technology as well as particle physics. In this context, PSI is operating, amongst others, a large proton accelerator facility since more than 30 years. In two cyclotrons, protons are accelerated to high speeds and then guided along roughly 100 m of beam line to three different target stations to produce secondary particles like mesons and neutrons for experiments and a separately beam line for UCN. The protons induce spallation processes in the target materials, and also at other beam loss points along the way, with emission of protons, neutrons, hydrogen, tritium, helium, heavier fragments and fission processes. In particular the produced neutrons, due to their large penetration depth, will then interact also with the surrounding materials. These interactions of radiation with matter lead to activation and partly to contamination of machine components and the surrounding infrastructures. Maintenance, operation and decommissioning of installations generate inevitably substantial amounts of radioactive operational and dismantling waste like targets, magnets, collimators, shielding (concrete, steel) and of course secondary waste. To achieve an optimal waste management strategy for interim storage or final disposal, radioactive waste has to be characterized, sorted and treated. This strategy is based on radiation protection demands, raw waste properties (size, material, etc.), and requirements to reduce the volume of waste, mainly for legal and economical reasons. In addition, the radiological limitations for transportation of the waste packages to a future disposal site have to be taken into account, as well as special regulatory demands. The characterization is a task of the waste producer. The conditioning processes and quality checks for radioactive waste packages are part of an accredited

    Angular correlation of annihilation radiation (ACAR) is a well established technique for the investigation of the electronic structure. A major limitation of ACAR studies is the available positron flux at a small spot on the sample. For this reason, the focus of this work is put on the discussion of a newly developed source-sample stage of the new 2D-ACAR spectrometer at Technische Universität München which uses an optimized static magnetic field configuration to guide the positrons onto the sample. The achieved spot diameter is dFWHM = 5.4 mm, with a high efficiency over the whole energy spectrum of the 22Na positron source. The implications of the performance of the source-sample stage are discussed with regard to 2D-ACAR measurements of single crystalline α-quartz, which serves as a model system for the determination of the total resolution. A value of (1.53 × 1.64) mrad2 FWHM was achieved at room temperature.

    Shortly after bacteriologist Paul de Kruif had been dismissed from a research position at the Rockefeller Institute for Medical Research, he started contributing to a novel in collaboration with the future Nobel laureate Sinclair Lewis. The novel, Arrowsmith, would become one of the most famous satires on medicine and science. Using de Kruif's correspondence with his idol Jacques Loeb, this paper describes the many ways in which medical science is depicted in Arrowsmith. This article compares the novel with de Kruif's and Loeb's biographies, and (1) focuses on the struggles of the main character, Martin Arrowsmith, as an allegory of the institutionalisation of medical research in the US, (2) shows that (influenced by de Kruif) Sinclair's purpose is to caricaturise scientific work in modern medical research institutions anywhere and (3) shows that the novel depicts a reductionist philosophy of research that seems to contradict the "messiness" of medical practice.

    Transverse dipole and quadrupole modes have been excited in a one-component cesium ion plasma trapped in the Paul Trap Simulator Experiment (PTSX) in order to characterize their properties and understand the effect of their excitation on equivalent long-distance beam propagation. The PTSX device is a compact laboratory Paul trap that simulates the transverse dynamics of a long, intense charge bunch propagating through an alternating-gradient transport system by putting the physicist in the beam's frame of reference. A pair of arbitrary function generators was used to apply trapping voltage waveform perturbations with a range of frequencies and, by changing which electrodes were driven with the perturbation, with either a dipole or quadrupole spatial structure. The results presented in this paper explore the dependence of the perturbation voltage's effect on the perturbation duration and amplitude. Perturbations were also applied that simulate the effect of random lattice errors that exist in an accelerator with quadrupole magnets that are misaligned or have variance in their field strength. The experimental results quantify the growth in the equivalent transverse beam emittance that occurs due to the applied noise and demonstrate that the random lattice errors interact with the trapped plasma through the plasma's internal collective modes. Coherent periodic perturbations were applied to simulate the effects of magnet errors in circular machines such as storage rings. The trapped one component plasma is strongly affected when the perturbation frequency is commensurate with a plasma mode frequency. The experimental results, which help to understand the physics of quiescent intense beam propagation over large distances, are compared with analytic models.

    This report documents current (2005-06) baseline ground-water conditions in three basins within the West African Republic of Cape Verde (Mosteiros on Fogo, Ribeira Paul on Santo Ant?o, and Ribeira Faj? on S?o Nicolau) based on existing data and additional data collected during this study. Ground-water conditions (indicators) include ground-water levels, ground-water recharge altitude, ground-water discharge amounts, ground-water age (residence time), and ground-water quality. These indicators are needed to evaluate (1) long-term changes in ground-water resources or water quality caused by planned ground-water development associated with agricultural projects in these basins, and (2) the feasibility of artificial recharge as a mitigation strategy to offset the potentially declining water levels associated with increased ground-water development. Ground-water levels in all three basins vary from less than a few meters to more than 170 meters below land surface. Continuous recorder and electric tape measurements at three monitoring wells (one per basin) showed variations between August 2005 and June 2006 of as much as 1.8 meters. Few historical water-level data were available for the Mosteiros or Ribeira Paul Basins. Historical records from Ribeira Faj? indicate very large ground-water declines during the 1980s and early 1990s, associated with dewatering of the Galleria Faj? tunnel. More-recent data indicate that ground-water levels in Ribeira Faj? have reached a new equilibrium, remaining fairly constant since the late 1990s. Because of the scarcity of observation wells within each basin, water-level data were combined with other techniques to evaluate ground-water conditions. These techniques include the quantification of ground-water discharge (well withdrawals, spring discharge, seepage to springs, and gallery drainage), field water-quality measurements, and the use of environmental tracers to evaluate sources of aquifer recharge, flow paths, and ground

    Background Waiting list management at chronic pain clinics has become a serious problem throughout Canada. We analyzed the waiting list at the Centre hospitalier de l’Université de Montréal (CHUM) Pain Centre. Methods The present study is an observational, prospective study. We used a specifically designed survey questionnaire. Survey findings were analyzed with descriptive statistical methods. Results A total of 270 patients were contacted; only 146 were included. Of these, 93 were women and 53 men. The average age was 55.9 years. Fifty-two percent of the patients were referred by a medical specialist; 34% by family physicians; 3% for emergency; and 11% unknown. The mean for pain score was 6.7/10. Seventy-three percent were taking pain killers with an average improvement on their pain score of 52%. Ten percent of respondents were not taking any type of analgesic medication, while 17% were taking over-the-counter drugs. Fifty-three percent of the patients had been suffering from chronic pain for 5 years or less, while 10% had been suffering and awaiting specialized pain treatment for more than 20 years. Conclusion Our data suggests that accessibility to specialized health care is not the sole obstacle to the timely and effective management of chronic pain. Seventy-three percent of the patients were taking some form of pharmaceutical treatment for pain and reported an average improvement rate of 52% on their pain score under medication. Such inconsistency may be attributable to patients’ lack of compliance with their treatment. The World Health Organization Working Group recommended in chronic patients a novel approach to health care, based on patient therapeutic education. Our results show that patients need to acquire self-management skills regarding their chronic conditions. PMID:23874120

    Introduction Les maladies cardiovasculaires (MCV) constituent l'une des principales causes de mortalité dans les pays en développement. Le dépistage de ces dernières chez des jeunes est un défi dans la lutte contre leur expansion. Le but de cette étude était de dépister ces maladies au sein d'une population jeunes d’étudiants camerounais. Methodes Deux mille six cent cinquante-huit étudiants de l'Université de Douala (23,6 ± 2,9 ans, sex-ratio H/F = 0,9) ont en Avril - Mai 2011 participé à une campagne de dépistage gratuit du diabète, de l'hypertension artérielle (HTA) et de l'obésité. Ils ont également été soumis à une d'enquête évaluant leur niveau en activités physiques et sportives (APS). Resultats 12,7% des participants avaient une pression artérielle (PA) ≥ 140/90 mmHg, 3,6% étaient obèses et 0,9% avaient une glycémie ≥1,26 g/L. Des corrélations ont été trouvées entre certains facteurs de risque (diabète, hypertension et obésité) et le niveau académique d'une part (r =0,366; p < 0,0001) et le temps passé devant la télévision d'autres part (r = 0,411; p < 0,0001). L‘APS était inversement corrélée à l‘âge (r =-0,015; p < 0,0001) et au temps passé devant la télévision (r = -0,059; p = 0,002). Conclusion La présence des MCV et leurs facteurs de risque mis en évidence dans cette étude réalisée en milieu estudiantin camerounais interpelle à une prévention et une éducation dans la lutte contre ces dernières.

  13. Non-destructive Investigation of "The Violinist" a Lead Sculpture by Pablo Gargallo, Using the Neutron Imaging Facility NEUTRA in the Paul Scherrer Institute

    Masalles, Alex; Lehmann, Eberhard; Mannes, David

    The Violinist (1920), the only sculpture made by Gargallo using lead sheet and wood, is being corroded by carbonation, most probably due to the organic vapours released by the wood inside, a material not chemically compatible with lead. Hydrogen plasma has been tested and proved to be an effective treatment meaning that the sculpture has to be dismantled in order to give the plasma gas access to the lead carbonate crusts on the inner surface of the lead sheet. Prior to dismantling, a complete exploration and diagnosis of this lead sculpture has been carried out through neutron imaging at the Paul Scherrer Institute. This non-destructive technique has produced different sets of images including radiography, tomography and 3D reconstruction. Despite the presence of a core made of an organic material such as wood, the digital processing of the images and their in depth visual analysis have yielded new three-dimensional information of inaccessible details of the sculpture, allowing us to assess its present state of conservation and the manufacturing technique and materials used by the artist. The results presented in this article highlight how information from neutron imaging can be of great value when it comes to set the strategies for future conservation treatment

    A postcard that Freud sent to Paul Federn on May 18, 1905, documents a meeting of the Wednesday Society devoted to Sophocles' Electra and to the controversial adaptation by Hugo von Hofmannsthal. The debate surrounding Hofmannsthal's play had already ignited on the occasion of its world premiere in Berlin in October 1903. Freud and the other members of the Wednesday group would have gathered first impressions from the predominantly negative theater reviews in Berlin newspapers and, above all, in a hostile pan of the play published in the influential Viennese daily Neue Freie Presse. As late as the summer of 1904 essays appeared in prominent journals such as Die Fackel and Die Zukunft, in which Electra was defended and praised, alternately, as a character embodying radical sublimation or as a modern hysteric based on the findings of Breuer and Freud. A statement of Freud's, made in 1909, suggests that the outcome of the 1905 discussion had been a negative one. The few traces of the Electra myth in Freud's later remarks and publications point to productive resistance that contributed in the years 1907-1910 to a firmer theoretical grounding of the Oedipus complex.

    Purpose: To evaluate the clinical results of fractionated spot-scanning proton radiation therapy (PT) in 26 pediatric patients treated at Paul Scherrer Institute for chordoma (CH) or chondrosarcoma (CS) of the skull base or axial skeleton. Methods and Materials: Between June 2000 and June 2010, 19 CH and 7 CS patients with tumors originating from the skull base (17) and the axial skeleton (9) were treated with PT. Mean age at the time of PT was 13.2 years. The mean prescribed dose was 74 Gy (relative biological effectiveness [RBE]) for CH and 66 Gy (RBE) for CS, at a dose of 1.8-2.0 Gy (RBE) per fraction. Results: Mean follow-up was 46 months. Actuarial 5-year local control (LC) rates were 81% for CH and 80% for CS. Actuarial 5-year overall survival (OS) was 89% for CH and 75% for CS. Two CH patients had local failures: one is alive with evidence of disease, while the other patient succumbed to local recurrence in the surgical pathway. One CS patient died of local progression of the disease. No high-grade late toxicities were observed. Conclusions: Spot-scanning PT for pediatric CH and CS patients resulted in excellent clinical outcomes with acceptable rates of late toxicity. Longer follow-up time and larger cohort are needed to fully assess tumor control and late effects of treatment.

    Sudden transitions from effusive or mildly explosive eruptions to violent phreatomagmatic explosive activity can occur at high-elevation vents on oceanic island volcanoes. Here, we describe near-vent deposits around the large Cova de Paul crater on Santo Antao, Cape Verde Islands, which provide insights into the transition from Strombolian magmatic to violently explosive phreatomagmatic activity during one such eruption. The Strombolian deposits change from welded spatter to bedded clinkery scoria to angular blocky scoria, and contain a distinct population of strongly banded, low-vesicularity angular sub-glassy clasts with strongly prolate vesicles. These sub-glassy clasts also form a discrete layer of larger blocks at the transition to the overlying phreatomagmatic deposits. They are compositionally identical to the Strombolian scoria and are interpreted to be fragments of flow-banded chilled margins from the walls of the eruptive conduit. The layer of large sub-glassy blocks records disintegration and expulsion of the chilled margins at the transition to phreatomagmatic activity. We interpret the sequence from spatter through clinkery scoria to blocky scoria as recording an increase in groundwater inflow into the conduit from pressurised aquifers, but at coolant input ratios below those required for explosions. The shattering of the chilled margins to produce the bed of large sub-glassy blocks appears to have allowed a much greater water flow into the conduit, leading to the phreatomagmatic explosive phase of the eruption.

    On March 14th of this year, the birthday of Paul Ehrlich, the great German researcher and 'founder of chemotherapy', returned for the 150th time. Interestingly, his later colleague Emil von Behring was born one day later in 1854. Both were coworkers in Robert Koch's laboratory and became Nobel Prize laureates (for their work in immunology), making great contributions to antiinfectious treatments. Emil von Behring's approach was through the use of immunological agents, while Ehrlich favored an approach of antiinfectious treatment by chemical agents. Through an ingenious concept that was a clear continuation of his early days in research with dyes, he found the first chemotherapeutic agents. From his dye work, he had concluded the following: if there are dyes that one can use to stain cells, why not develop pharmacological agents that, like stains, also attach to a structure in the living pathogen and kill them. He gave these agents the emotionally charged name 'magic bullets'. This introductory review will initiate a series of papers on the occasion of Ehrlich's 150th birthday and the 'World Conference on Dosing of Antiinfectives: Dosing the Magic Bullets', which is going to be held in Nürnberg, Germany, from September 9 to 11, 2004 (see www.ehrlich2004.org). Apart from the conference topic, this conference will also commemorate a real science giant of the last century and yet a modest human being whom, as Robert Koch put it, 'one had to like'. This article recalls Ehrlich's ingenious concepts, including modern syphilis treatment, one-dose treatment ('therapia magna sterilisans') of Helicobacter pylori infections and introduction of an arsenic compound, arsenic trioxide, as well as experiments and new exciting data on Congo red, a well-known 'non-Ehrlich dye'.

    Temporal and spatial variability in wetland water-quality variables were examined for twenty-one wetlands in the Minneapolis/St. Paul metropolitan area and eighteen wetlands in adjacent Wright County. Wetland water quality was significantly affected by contact with the sediment (surface water vs. groundwater), season, degree of hydrologic isolation, wetland class, and predominant land-use in the surrounding watershed (p<0.05). Between years, only nitrate and particulate nitrogen concentrations varied significantly in Wright County wetland surface waters. For eight water-quality variables, the power of a paired before-and-after comparison design was greater than the power of a completely randomized design. The reverse was true for four other water-quality variables. The power of statistical tests for different classes of water-quality variables could be ranked according to the predominant factors influencing these: climate factors>edaphic factors>detritivory>land-use factors>biotic-redox or other multiple factors.For two wetlands sampled intensively, soluble reactive phosphate and total dissolved phosphorus were the most spatially variable (c.v.=76-249%), while temperature, color, dissolved organic carbon, and DO were least variable (c.v.=6-43%). Geostatistical analyses demonstrated that the average distance across which water-quality variables were spatially correlated (variogram range) was 61-112% of the mean radius of each wetland. Within the shallower of the two wetlands, nitrogen speciation was explained as a function of dissolved oxygen, while deeper marsh water-quality variables were explained as a function of water depth or distance from the wetland edge. Compositing water-quality samples produced unbiased estimates of individual sample means for all water quality variables examined except for ammonium. PMID:24198069

    The aim of this study was to investigate the planktonic and the holobiont Madracis decactis (Scleractinia) microbial diversity along a turbulence-driven upwelling event, in the world's most isolated tropical island, St Peter and St Paul Archipelago (SPSPA, Brazil). Twenty one metagenomes were obtained for seawater (N = 12), healthy and bleached holobionts (N = 9) before, during and after the episode of high seawater turbulence and upwelling. Microbial assemblages differed between low turbulence-low nutrient (LLR) and high-turbulence-high nutrient (HHR) regimes in seawater. During LLR there was a balance between autotrophy and heterotrophy in the bacterioplankton and the ratio cyanobacteria:heterotrophs ~1 (C:H). Prochlorales, unclassified Alphaproteobacteria and Euryarchaeota were the dominant bacteria and archaea, respectively. Basic metabolisms and cyanobacterial phages characterized the LLR. During HHR C:H < < 0.05 and Gammaproteobacteria approximated 50% of the most abundant organisms in seawater. Alteromonadales, Oceanospirillales, and Thaumarchaeota were the dominant bacteria and archaea. Prevailing metabolisms were related to membrane transport, virulence, disease, and defense. Phages targeting heterotrophs and virulence factor genes characterized HHR. Shifts were also observed in coral microbiomes, according to both annotation-indepent and -dependent methods. HHR bleached corals metagenomes were the most dissimilar and could be distinguished by their di- and tetranucleotides frequencies, Iron Acquision metabolism and virulence genes, such as V. cholerae-related virulence factors. The healthy coral holobiont was shown to be less sensitive to transient seawater-related perturbations than the diseased animals. A conceptual model for the turbulence-induced shifts is put forward.

    Introduction The US Department of Agriculture has stocking criteria for healthy foods among Supplemental Nutrition Assistant Program (SNAP)-authorized retailers. Increased access to healthy food could improve diet quality among SNAP participants, which has implications for chronic disease prevention. The objective of this study was to quantify healthy foods stocked in small-size to mid-size retailers who are authorized under SNAP but not under the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Methods We used formative, cross-sectional data from a large policy evaluation to conduct secondary analyses. Store audits were conducted in 2014 in 91 randomly selected, licensed food stores in Minneapolis and St. Paul, Minnesota. Supermarkets and retailers participating in WIC, which are required to stock healthy foods, were excluded as were other stores not reasonably expected to stock staple foods, such as specialty stores or produce stands. Availability of milk, fruits, vegetables, and whole-grain–rich foods was assessed. Results The 91 stores studied were corner stores, food–gas marts, dollar stores, and pharmacies. More than half carried 1 or more varieties of fat-free or low-fat milk, fresh or canned fruit, and whole-grain–rich cereal. However, only one-third stocked 1 or more varieties of fresh vegetables and only one-quarter stocked whole-grain–rich products, such as whole-grain-rich bread (26%) or tortillas (21%) or brown rice (25%). Few stores stocked at least 2 varieties of each product. Conclusions Many stores did not stock a variety of healthy foods. The US Department of Agriculture should change policies to improve minimum stocking requirements for SNAP-authorized retailers. PMID:26312380

    How extraintestinal pathogenic Escherichia coli (ExPEC) and antimicrobial-resistant E. coli disseminate through the population is undefined. We studied public restrooms for contamination with E. coli and ExPEC in relation to source and extensively characterized the E. coli isolates. For this, we cultured 1,120 environmental samples from 56 public restrooms in 33 establishments (obtained from 10 cities in the greater Minneapolis-St. Paul, MN, metropolitan area in 2003) for E. coli and compared ecological data with culture results. Isolates underwent virulence genotyping, phylotyping, clonal typing, pulsed-field gel electrophoresis (PFGE), and disk diffusion antimicrobial susceptibility testing. Overall, 168 samples (15% from 89% of restrooms) fluoresced, indicating presumptive E. coli: 25 samples (2.2% from 32% of restrooms) yielded E. coli isolates, and 10 samples (0.9% from 16% of restrooms) contained ExPEC. Restroom category and cleanliness level significantly predicted only fluorescence, gender predicted fluorescence and E. coli, and feces-like material and toilet-associated sites predicted all three endpoints. Of the 25 E. coli isolates, 7 (28%) were from phylogenetic group B2(virulence-associated), and 8 (32%) were ExPEC. ExPEC isolates more commonly represented group B2 (50% versus 18%) and had significantly higher virulence gene scores than non-ExPEC isolates. Six isolates (24%) exhibited ≥3-class antibiotic resistance, 10 (40%) represented classic human-associated sequence types, and one closely resembled reference human clinical isolates by pulsed-field gel electrophoresis. Thus, E. coli, ExPEC, and antimicrobial-resistant E. coli sporadically contaminate public restrooms, in ways corresponding with restroom characteristics and within-restroom sites. Such restroom-source E. coli strains likely reflect human fecal contamination, may pose a health threat, and may contribute to population-wide dissemination of such strains. PMID:25911488

    The St. Paul Fracture Zone (FZ) in the equatorial Atlantic is interrupted by three intratransform ridge (ITR) spreading centers. A detailed magnetic survey, corrected for the diurnal variations using a moored magnetic station, six submersible dives, and three bottom-towed video camera tracks provide data on the most eastern ITR (0°37'N, 25°27'W). Visual observations and submersible sampling displayed a high ultramafic/volcanic ratio, supporting the assumption that the ITR is in a magmatically starved state. Volcanics were mainly found on the rift valley floor from 4700 to 4000 m and as a thin cap (<160 m) on the top of the eastern rift crest (2700 m). Most of the rift walls consist essentially of serpentinized peridotites and gabbros. The magnetic data show a well-defined ridge centered anomaly. A generalized inversion method was applied to the field data to calculate the crustal equivalent magnetization, assuming that the seafloor is broken down into elementary cells of 1 × 1 × 0.5 km3 which fit the topography. The average of absolute value of equivalent magnetization is 2.7 A m-1. The width of the central normal polarity (Brunhes epoch) is wider (at least 34 km) than that indicated by the NUVEL-1 kinematic model (24.5 km). This 40% excess is believed to be significant and is thought to be the result of prolonged chemical remanent magnetization acquired during the serpentinization of peridotites. In a magmatically starved accretion segment, we suggest that peridotites could continue to acquire magnetization as long as tectonic activities facilitate the circulation of seawater in the upper mantle.

    The hydrogeology at three areas along the Mississippi and Minnesota Rivers in the Minneapolis-St. Paul area were studied to characterize ground-water discharge from bedrock aquifers to the two rivers. Along the Mississippi River between Fridley and Brooklyn Center, a buried valley underlying the Mississippi River cuts through the overlying terrace deposits and glacial-drift deposits into two underlying bedrock hydro- geologic units: the St Peter aquifer, and a rubble zone between the St. Peter and Prairie du Chien-Jordan aquifers. Shallow ground-water flow in the near-surface gray and upper red tills and sand and gravel outwash aquifer discharges to springs along the edge of the river. Ground water flowing through the rubble zone and upper part of the Prairie du Chien-Jordan aquifer probably discharges through alluvial deposits to the river. In study area 2, along the Minnesota River between Eagan and Bloomington, almost 200 feet of post-glacial alluvium, glaciofluvial sand and gravel, Pleistocene lake deposits, and peat fill a bedrock valley under the present-day Minnesota River. As much as 40 feet of post-glacial peat, silty clay, clay, and muck lie near the river-valley walls. Confining units beneath the river channel impede the discharge of ground water from the underlying Prairie du Chien-Jordan aquifer to the river. Ground water discharges to wetlands, lakes, and springs along both the north and south side of the river. Along the Mississippi River at Minneapolis about 5 miles upstream of the confluence of the Minnesota and Mississippi Rivers, the Mississippi River lies in a post-glacial valley cut through thin glacial drift into the St. Peter aquifer. Beneath the river, ground water flows from the St. Peter aquifer through the overlying post-glacial ailuvium to the Mississippi River. No confining unit separates the St. Peter aquifer and the river.

  5. Quality of acute stroke care improvement framework for the Paul Coverdell National Acute Stroke Registry: facilitating policy and system change at the hospital level.

    The Paul Coverdell National Acute Stroke Registry prototypes baseline data collection demonstrated a significant gap in the use of evidenced-based interventions. Barriers to the use of these interventions can be characterized as relating to lack of knowledge, attitudes, and ineffective behaviors and systems. Quality improvement programs can address these issues by providing didactic presentations to disseminate the science and peer interactions to address the lack of belief in the evidence, guidelines, and likelihood of improved patient outcomes. Even with knowledge and intention to provide evidenced-based care, the absence of effective systems is a significant behavioral barrier. A program for quality improvement that includes multidisciplinary teams of clinical and quality improvement professionals has been successfully used to carry out redesign of stroke care delivery systems. Teams are given a methodology to set goals, test ideas for system redesign, and implement those changes that can be successfully adapted to the hospital's environment. Bringing teams from several hospitals together substantially accelerates the process by sharing examples of successful change and by providing strategies to support the behavior change necessary for the adoption of new systems. The participation of many hospitals also creates momentum for the adoption of change by demonstrating observable and successful improvement. Data collection and feedback are useful to demonstrate the need for change and evaluate the impact of system change, but improvement occurs very slowly without a quality improvement program. This quality improvement framework provides hospitals with the capacity and support to redesign systems, and has been shown to improve stroke care considerably, when coupled with an Internet-based decision support registry, and at a much more rapid pace than when hospitals use only the support registry.

    The existing literature on the development of recombinant DNA technology and genetic engineering tends to focus on Stanley Cohen and Herbert Boyer's recombinant DNA cloning technology and its commercialization starting in the mid-1970s. Historians of science, however, have pointedly noted that experimental procedures for making recombinant DNA molecules were initially developed by Stanford biochemist Paul Berg and his colleagues, Peter Lobban and A. Dale Kaiser in the early 1970s. This paper, recognizing the uneasy disjuncture between scientific authorship and legal invention in the history of recombinant DNA technology, investigates the development of recombinant DNA technology in its full scientific context. I do so by focusing on Stanford biochemist Berg's research on the genetic regulation of higher organisms. As I hope to demonstrate, Berg's new venture reflected a mass migration of biomedical researchers as they shifted from studying prokaryotic organisms like bacteria to studying eukaryotic organisms like mammalian and human cells. It was out of this boundary crossing from prokaryotic to eukaryotic systems through virus model systems that recombinant DNA technology and other significant new research techniques and agendas emerged. Indeed, in their attempt to reconstitute 'life' as a research technology, Stanford biochemists' recombinant DNA research recast genes as a sequence that could be rewritten thorough biochemical operations. The last part of this paper shifts focus from recombinant DNA technology's academic origins to its transformation into a genetic engineering technology by examining the wide range of experimental hybridizations which occurred as techniques and knowledge circulated between Stanford biochemists and the Bay Area's experimentalists. Situating their interchange in a dense research network based at Stanford's biochemistry department, this paper helps to revise the canonized history of genetic engineering's origins that emerged during

  8. Influence of Protein Synthesis on NO3− Reduction, NH4+ Accumulation, and Amide Synthesis in Suspension Cultures of Paul's Scarlet Rose

    Changes in the concentrations of NH4+ and amides during the growth of suspension cultures of rose (Rosa cv. Paul's Scarlet) cells were examined. When cells were grown in medium possessing only NO3− as a nitrogen source, the concentrations of NH4+ and amides increased to 4.0 × 10−1 and 5.9 micromoles per gram fresh weight, respectively. The amounts of both constituents declined during the later stages of growth. When a trace amount of NH4+ was added to the NO3− base starting medium, the concentration of NH4+ in the cells was increased to 7.0 × 10−1 micromoles per gram fresh weight. A comparison between the concentration of NH4+ in the cells (4.3 × 10−4 molar) with the Km values for glutamate dehydrogenase (5 × 10−3 molar) and glutamine synthetase (1.7 × 10−5 molar) showed that the endogenous NH4+ would have to be concentrated 10-fold in compartments possessing glutamate dehydrogenase in order for the substrate to reach one-half the saturation level for that enzyme. The influence of protein synthesis on the level of NH4+ and amides was examined by blocking protein synthesis with cycloheximide or puromycin and measuring changes in NH4+ and amide concentration over the subsequent 4 hours. The level of both NH4+ and amides showed substantial increases when protein synthesis was blocked. Ammonium accumulated to concentrations surpassing those reported by other authors to be toxic to plants. The reduction of NO3− did not appear to be influenced by the blockage of protein synthesis.

    Since 2003 the High Resolution Stereo Camera (HRSC) experiment on the Mars Express mission is in orbit around Mars. First images were sent to Earth on January 14th, 2004. The goal-oriented HRSC data dissemination and the transparent representation of the associated work and results are the main aspects that contributed to the success in the public perception of the experiment. The Planetary Sciences and Remote Sensing Group at Freie Universität Berlin (FUB) offers both, an interactive web based data access, and browse/download options for HRSC press products [www.fu-berlin.de/planets]. Close collaborations with exhibitors as well as print and digital media representatives allows for regular and directed dissemination of, e.g., conventional imagery, orbital/synthetic surface epipolar images, video footage, and high-resolution displays. On a monthly basis we prepare press releases in close collaboration with the European Space Agency (ESA) and the German Aerospace Center (DLR) [http://www.geo.fu-berlin.de/en/geol/fachrichtungen/planet/press/index.html]. A release comprises panchromatic, colour, anaglyph, and perspective views of a scene taken from an HRSC image of the Martian surface. In addition, a context map and descriptive texts in English and German are provided. More sophisticated press releases include elaborate animations and simulated flights over the Martian surface, perspective views of stereo data combined with colour and high resolution, mosaics, and perspective views of data mosaics. Altogether 970 high quality PR products and 15 movies were created at FUB during the last decade and published via FUB/DLR/ESA platforms. We support educational outreach events, as well as permanent and special exhibitions. Examples for that are the yearly "Science Fair", where special programs for kids are offered, and the exhibition "Mars Mission and Vision" which is on tour until 2015 through 20 German towns, showing 3-D movies, surface models, and images of the HRSC

    Context. Stars are born together from giant molecular clouds and, if we assume that the priors were chemically homogeneous and well-mixed, we expect them to share the same chemical composition. Most of the stellar aggregates are disrupted while orbiting the Galaxy and most of the dynamic information is lost, thus the only possibility of reconstructing the stellar formation history is to analyze the chemical abundances that we observe today. Aims: The chemical tagging technique aims to recover disrupted stellar clusters based merely on their chemical composition. We evaluate the viability of this technique to recover co-natal stars that are no longer gravitationally bound. Methods: Open clusters are co-natal aggregates that have managed to survive together. We compiled stellar spectra from 31 old and intermediate-age open clusters, homogeneously derived atmospheric parameters, and 17 abundance species, and applied machine learning algorithms to group the stars based on their chemical composition. This approach allows us to evaluate the viability and efficiency of the chemical tagging technique. Results: We found that stars at different evolutionary stages have distinct chemical patterns that may be due to NLTE effects, atomic diffusion, mixing, and biases. When separating stars into dwarfs and giants, we observed that a few open clusters show distinct chemical signatures while the majority show a high degree of overlap. This limits the recovery of co-natal aggregates by applying the chemical tagging technique. Nevertheless, there is room for improvement if more elements are included and models are improved.

    2015-10-01

    Context. ζ Ori A is a hot star claimed to host a weak magnetic field, but no clear magnetic detection was obtained so far. In addition, it was recently shown to be a binary system composed of a O9.5I supergiant and a B1IV star. Aims: We aim at verifying the presence of a magnetic field in ζ Ori A, identifying to which of the two binary components it belongs (or whether both stars are magnetic), and characterizing the field. Methods: Very high signal-to-noise spectropolarimetric data were obtained with Narval at the Bernard Lyot Telescope (TBL) in France. Archival HEROS, FEROS and UVES spectroscopic data were also used. The data were first disentangled to separate the two components. We then analyzed them with the least-squares deconvolution technique to extract the magnetic information. Results: We confirm that ζ Ori A is magnetic. We find that the supergiant component ζ Ori Aa is the magnetic component: Zeeman signatures are observed and rotational modulation of the longitudinal magnetic field is clearly detected with a period of 6.829 d. This is the only magnetic O supergiant known as of today. With an oblique dipole field model of the Stokes V profiles, we show that the polar field strength is ~140 G. Because the magnetic field is weak and the stellar wind is strong, ζ Ori Aa does not host a centrifugally supported magnetosphere. It may host a dynamical magnetosphere. Its companion ζ Ori Ab does not show any magnetic signature, with an upper limit on the undetected field of ~300 G.

    Neiner, C.; Grunhut, J.; Leroy, B.; De Becker, M.; Rauw, G.

    2015-03-01

    Context. Some colliding-wind massive binaries, called particle-accelerating colliding-wind binaries (PACWB), exhibit synchrotron radio emission, which is assumed to be generated by a stellar magnetic field. However, no measurement of magnetic fields in these stars has ever been performed. Aims: We aim at quantifying the possible stellar magnetic fields present in PACWB to provide constraints for models. Methods: We gathered 21 high-resolution spectropolarimetric observations of 9 PACWB available in the ESPaDOnS, Narval and HarpsPol archives. We analysed these observations with the least squares deconvolution method. We separated the binary spectral components when possible. Results: No magnetic signature is detected in any of the 9 PACWB stars and all longitudinal field measurements are compatible with 0 G. We derived the upper field strength of a possible field that could have remained hidden in the noise of the data. While the data are not very constraining for some stars, for several stars we could derive an upper limit of the polar field strength of the order of 200 G. Conclusions: We can therefore exclude the presence of strong or moderate stellar magnetic fields in PACWB, typical of the ones present in magnetic massive stars. Weak magnetic fields could however be present in these objects. These observational results provide the first quantitative constraints for future models of PACWB.

    Neiner, C.; Tkachenko, A.; MiMeS Collaboration

    2014-03-01

    Aims: A magnetic field can have a strong impact on the evolution of a binary star. However, only a dozen magnetic OB binaries are known as of today and are available to study this effect, including some very few magnetic pulsating spectroscopic OB binaries. We checked for the presence of a magnetic field in the B5IV hierarchical triple system HD 1976 with spectropolarimetric data obtained with Narval at the Bernard Lyot Telescope (TBL). Methods: We used orbital parameters of HD 1976 available in the literature to disentangle the Narval intensity spectra. We computed Stokes V profiles with the least squares deconvolution technique to search for magnetic signatures. We then derived an estimate of the longitudinal magnetic field strength for each observation and for various line lists. Results: Our disentangling of the intensity spectra shows that HD 1976 is a double-lined spectroscopic (SB2) binary, the lines of the secondary component are about twice as broad as those of the primary component. We did not identify the third component. Moreover, we find clear magnetic signatures in the spectropolarimetric measurements of HD 1976 that seem to be associated with the primary component. We conclude that HD 1976 is a magnetic slowly pulsating double-lined spectroscopic binary star with an undetected third component. It is the second such example known (the other is HD 25558).

  15. An attempt to detect the dust disk of VEGA by photopolarimetry, and constraints on the grain size

    NASA Astrophysics Data System (ADS)

    Mauron, N.; Dole, H.

    1998-09-01

    We report on a first attempt to detect Vega's disk through optical scattered light by using linear photopolarimetry. Polarization measurements on the aureole of Vega were carried out between 7'' and 30'' from the star with a 10'' diameter hole and down to polarization level of ~ 10(-4) . No signal reliably attributable to circumstellar dust was detected, and an upper limit to the polarized surface brightness of the disk is derived. This upper limit for Vega's disk is about 200 times lower than the polarized brightness observed around beta Pic, at an angular offset of 15'' from the stars. The upper limit is also compared to a simple model, in which one assumes a plausible total dust mass of 2 10(-8) Msun, and a pole-on oriented disk with a typical radius of ~ 20'' as favoured by far-infrared and submillimetric experiments. We also suppose that the grains are spherical (Mie) particles. Our analysis can exclude that a major part of dust mass would consist of grains of 0.01-0.3 mu m, as in the interstellar medium. If a single size is assumed, the observational upper limit favours radii of at least 5-10 mu m or larger. If a size distribution including large particles ( ~ 300 mu m) is assumed, the data suggests that only a very small fraction ( ~ 1/1000 ) of the dust mass is in 0.01-0.3 mu m grains.

  16. Parametric Investigations of an Atmospheric pressure Uniform Glow Discharge in helium

    NASA Astrophysics Data System (ADS)

    Ben Gadri, Rami

    1997-11-01

    In the cold plasma processing field, applications of the atmospheric pressure uniform glow discharge are numerous. Among them one can mention the increase of the surface energy of materials, the cleaning and etching of surfaces, and the decontamination and sterilization. The development of the glow regime at atmospheric pressure permits to avoid the technical and economical drawbacks of low pressure glow discharge systems. It also increases the efficiency of the surface treatment as compared to the corona discharge. In these conditions, a glow regime is obtained and studied in particular experimental conditions. The working gas is helium, the frequency in the range 1-20 kHz, the gap distance of some mm and the metallic electrodes are covered by a dielectric layer. The current is characterized by one peak per half cycle and is typically in the range of a few tens of mA. Since this discharge involves complex nonlinear processes and is sensitive to the variation of its parameters, detailed experimental (Ph. Decomps (1996), PhD thesis, Universite Paul Sabatier Toulouse France, No d'ordre 2538.) and numerical studies, covering wide ranges of system parameters, were required. These investigations allowed the determination of the optimal operating conditions for which the discharge remains of the glow type, and therefore induces a better surface treatment. In this paper the detailed theory ( Ben Gadri R., Rabehi A., Massines F. and Segur P. (1994), XIIth Eur. Sect. Conf. on the At. & Mol. Phy. of Ionized Gases, The Netherlands, 23-26 August, pp. 228-229.) of the one dimensional f luid model and a parametric study of the discharge characteristics are presented. A particular attention will be given to the influence of the different system parameters on the operational mode of the discharge.

  17. Trapped Lee Waves Observed during PYREX by Constant Volume Balloons: Comparison with Meso-NH Simulations.

    The main objective of the present paper is the use of a constant volume balloon (CVB) as a tool to (i) study trapped lee waves and (ii) assess the forecasting capability of a nonhydrostatic numerical model. Then, CVB data obtained during the Pyrénées Experiment (PYREX) are compared with nonhydrostatic two-dimensional trapped lee waves simulated by the Meso-NH model. This model is a community research model based on the Lipps-Hemler form of the anelastic system, which has been recently developed by the CNRM of Météo-France and the Laboratoire d'Aérologie of Université Paul Sabatier in France.To analyze how the CVB responds to lee waves, a simple CVB model is first applied to academic atmospheric stationary wave flows, analogous to those encountered during PYREX. This model takes into account the vertical velocity of the surrounding air, geometrical parameters of the balloon, and the atmospheric heating processes. Results show that the CVB reacts well to the atmospheric wave period, with a phase delay of only a few minutes.Three CVB trajectories obtained during the third Intensive Observation Period of PYREX are then computed within Meso-NH 2D simulations from the balloon's starting point, using the CVB model. The simulated quantities are compared to the experimental CVB data, focusing especially on the lee-wave vertical movements. The simulated lee-wave vertical velocities and amplitude are found to be in good agreement with the observations, as shown by the statistical analysis. The computed CVB heights deviate by less than 13% from the altitude of the measured trajectories. This comparison of the model output to the CVB experimental data demonstrates the good performance of the Meso-NH model in the prediction of the vertical excursions of the lee waves.

    2016-03-01

    Aims: The main-sequence B-type star ζ Cassiopeiae is known as a N-rich star with a magnetic field discovered with the Musicos spectropolarimeter. We model the magnetic field of the star by means of 82 new spectropolarimetric observations of higher precision to investigate the field strength, topology, and effect. Methods: We gathered data with the Narval spectropolarimeter installed at Télescope Bernard Lyot (TBL; Pic du Midi, France) and applied the least-squares deconvolution technique to measure the circular polarisation of the light emitted from ζ Cas. We used a dipole oblique rotator model to determine the field configuration by fitting the longitudinal field measurements and by synthesizing the measured Stokes V profiles. We also made use of the Zeeman-Doppler imaging technique to map the stellar surface and to deduce the difference in rotation rate between the pole and equator. Results: ζ Cas exhibits a polar field strength Bpol of 100-150 G, which is the weakest polar field observed so far in a massive main-sequence star. Surface differential rotation is ruled out by our observations and the field of ζ Cas is strong enough to enforce rigid internal rotation in the radiative zone according to theory. Thus, the star rotates as a solid body in the envelope. Conclusions: We therefore exclude rotationally induced mixing as the cause of the surface N-enrichment. We discuss that the transport of chemicals from the core to the surface by internal gravity waves is the most plausible explanation for the nitrogen overabundance at the surface of ζ Cas.

    The characterization of microbial communities within urban lake sediments may offer a promising method to observe changes in lake geochemistry due to human impact. By mapping the abundances and diversity of microorganisms through the uppermost meter of sediment in three distinctive Minneapolis-St. Paul lakes (Brownie Lake and Twin Lake, both meromictic, and oligomictic Lake McCarrons) using 16S rRNA characterization, our aim was to observe changes in microbial populations across steep geochemical and lithological gradients. Lake McCarrons underwent a process of eutrophication and a shift to bottom water anoxia beginning around 1910 due mostly to agricultural run-off. This shift greatly increased the preservation potential of seasonal sedimentation and finely laminated varve accumulation. The onset of meromixis in Brownie Lake in ~1915 is abrupt and has been attributed to a sudden drop in water level. Twin Lake is perennially meromictic due to the topography of the watershed. The three lakes were sampled by collecting freeze cores in July, 2012 (McCarrons, Brownie) and February, 2013 (Twin) at the deepest locations beneath anoxic to hypoxic bottom waters. The cores were then subsampled with high resolution techniques at places of interest: within individual lamina, across mass flow deposits, and near the onset of laminae preservation (beginning of oxygen-depleted bottom waters). Terminal Restriction Fragment Length Polymorphism (T-RFLP) allows for comparison of the microbial assemblages throughout the sediment columns of each lake and from lake to lake, with a focus on the horizons mentioned previously. The microbial assemblages present in specific horizons are often introduced via sedimentation and are partially derived from community composition at the time of sedimentation. T-RFLP analyses are complemented by mineralogical and lithological descriptions. The lakes have each been subject to their own set of variables and inputs. Brownie Lake contains high levels of

    Die E-Mail-Infrastruktur an der Technischen Universität München (TUM) ist historisch bedingt sehr heterogen und komplex. Viele Einrichtungen müssen wertvolle Arbeitskraft auf die Administration eigener Mailserver verwenden. Auf der anderen Seite wird bei einigen Einrichtungen der Ruf nach Groupware-Funktionalitäten wie z.B. gemeinsame Kalender immer lauter. Das Teilprojekt E-Mail stellt einen zentralen Mail- und Groupware-Service bereit, der den Einrichtungen ermöglichen soll, den Betrieb eigener Server und zugehöriger Systeme (etwa lokaler Benutzerverwaltungen) für diesen Zweck aufzugeben und diese Dienste an das Teilprojekt E-Mail zu migrieren, ohne ihre Verwaltungshoheit oder ihre Maildomains aufgeben zu müssen. Dieser Service versteht sich als eine Ergänzung zur bestehenden Grundversorgung der TUM mit den Maildiensten des myTUM-Mailers, ist mandantenfähig aufgebaut und kann daher künftig neben der TUM auch weiteren Organisationen im Münchner Wissenschaftsnetz zur Verfügung gestellt werden.

    This study evaluated the usefulness of the anti-HBc, hepatitis C virus antibodies (anti-HCV), human T cell lymphotropic virus I and II antibodies (anti-HTLV I/II), serologic tests for syphilis, and surface antigen of hepatitis B virus (HBsAg) as surrogate markers for the risk for HIV infection in 80,284 serum samples from blood donors from the Blood Bank of "Hospital Universitário Regional Norte do Paraná", Londrina, Paraná State, Brazil, analyzed from July 1994 to April 2001. Among 39 blood donors with positive serology for HIV, 12 (30.8%) were anti-HBc positive, 10 (25.6%) for anti-HCV, 1 (2.6%) for anti-HTLV I/I, 1 (2.6%) was positive for syphilis, and 1 (2.6%) for HBsAg. Among the donors with negative serology for HIV, these markers were detected in 8,407 (10.5%), 441 (0.5%), 189 (0.2%), 464 (0.6%), and 473 (0.6%) samples, respectively. The difference was statistically significant (p < 0.001) for anti-HBc and anti-HCV. Although the predictive positive values for these surrogate markers were low for HIV infection, the results confirmed the anti-HBc and anti-HCV as useful surrogate markers for HIV infection thus reinforcing the maintenance of them in the screening for blood donors contributing to the prevention of the small number of cases in which HIV is still transmitted by transfusion.

    Epidermolysis bullosa comprises a group of phenotypically different genodermatosis, hereditary or acquired, characterized by skin fragility and subsequent formation of blisters in response to mechanical trauma, and which may also affect mucous membranes. This study aimed to analyze the relation between the nutritional, hematologic, infectious characteristics and the type of epidermolysis bullosa, through a descriptive case study based on data from medical records of 10 patients with epidermolysis bullosa assisted regularly at the Dermatology Clinic of the Hospital Universitário de Brasília. The old classification of the type of epidermolysis bullosa, weight and height, blood count, white blood cell count, platelet count and description of the type and frequency of secondary infections during the service were considered. We verified a predominance of iron deficiency anemia, chronic leukocytosis, thrombocytosis, chronic malnutrition, low height for age and thinness, and people with epidermolysis bullosa simplex exhibited appropriate relation between height/age and BMI/age. The non-specific skin infection was the most prevalent in both sexes. The severity of the type of epidermolysis bullosa and frequency of secondary infections did not form a directly proportional relation. The absence of direct proportion in all cases between the type of epidermolysis bullosa and the analysis parameters suggest a possible significant interference from other aspects such as the extent of the affected skin area, extracutaneous type of engagement and specific genetic mutation. The inclusion of these factors in the new classification proposed by Fine et al can contribute significantly to a better correlation of clinical parameters and appropriate preventive and therapeutic approaches.

Binarity and the magnetic field may also significantly affect the fate of massive stars. Aims: Our goal is to investigate the evolution of single O stars in the Galaxy. Methods: For that, we used a sample of 74 objects comprising all luminosity classes and spectral types from O4 to O9.7. We relied on optical spectroscopy obtained in the context of the MiMeS survey of massive stars. We performed spectral modelling with the code CMFGEN. We determined the surface properties of the sample stars, with special emphasis on abundances of carbon, nitrogen, and oxygen. Results: Most of our sample stars have initial masses in the range of 20 to 50 M⊙. We show that nitrogen is more enriched and carbon and oxygen are more depleted in supergiants than in dwarfs, with giants showing intermediate degrees of mixing. CNO abundances are observed in the range of values predicted by nucleosynthesis through the CNO cycle. More massive stars, within a given luminosity class, appear to be more chemically enriched than lower mass stars. We compare our results with predictions of three types of evolutionary models and show that for two sets of models, 80% of our sample can be explained by stellar evolution including rotation. The effect of magnetism on surface abundances is unconstrained. Conclusions: Our study indicates that in the 20-50 M⊙ mass range, the surface chemical abundances of most single O stars in the Galaxy are fairly well accounted for by stellar evolution of rotating stars.

    In this study we analyze magnetic field data provided by Venus Express (VEX) between 2007 and 2008. During each of the probe's eccentric polar orbit around Venus, VEX performs plasma and magnetic field measurements in the environment around the planet both in Venus induced magnetosphere and in the solar wind at several tens of thousands of kilometers away from the magnetosphere. This latter data set has a unique scientific value as it provides observations of magnetic turbulence in the solar wind around 0.72 AU, in the vicinity of Venus. We discuss a semi-automated method to select solar wind magnetic field data at 1 Hz from Venus Express Magnetometer (MAG) data by using plasma data from the Analyser of Space Plasma and Energetic Atoms (ASPERA). The time intervals when VEX is in the solar wind are automatically determined for 2007 and 2008. We apply a Fourier transform on the selected data and calculate the power spectral densities (PSD) of the turbulent magnetic field through Welch's algorithm. We compute the PSD of the three components of the magnetic field for the time intervals when both MAG and ASPERA were operating in the solar wind, for each VEX orbit between 1st of January 2007 and 31st of December 2008. The data base includes a number of 374 individual spectra. We discuss the spectral properties of turbulence and illustrate similarities between fast and slow wind during the minimum phase of the solar cycle for each of VEX's orbit which satisfies the selection criteria for a period of two years.

    Introduction Plusieurs facteurs dont les notes obtenues au BAC peuvent influencer les performances académiques des étudiants en première année de médecine. L'objectif de cette étude était d’évaluer la relation entre les résultats des étudiants au BAC et le succès en première année de médecine. Méthodes Nous avons réalisé une étude analytique ayant inclus l'ensemble des étudiants régulièrement inscrits en première année à la Faculté de Médecine de l'université de Parakou durant l'année académique 2010-2011. Les données concernant les notes par discipline et mention obtenue au BAC ont été collectées. Une analyse multivariée utilisant la régression logistique et la régression linéaire multiple a permis d’établir les meilleurs prédicteurs du succès et de la moyenne de l’étudiant en fin d'année. Le logiciel SPSS version 17.0 a été utilisé pour l'analyse des données et un p<0,05 a été considéré comme statistiquement significatif. Résultats Parmi les 414 étudiants régulièrement inscrits les données de 407 ont pu être exploitées. Ils étaient âgés de 15 à 31 ans; 262 (64,4%) étaient de sexe masculin. 98 étaient admis avec un taux de succès de 23,7%. Le sexe masculin, la note obtenue en mathématiques, en sciences physiques, la moyenne au BAC et la mention étaient associés au succès en fin d'année mais en analyse multivariée seule une note en sciences physiques > 15/20 était associée au succès (OR: 2,8 [1,32- 6,00]). Pour la moyenne générale obtenue en fin d'année seule une mention bien obtenue au BAC était associée (coefficient de l'erreur standard: 0,130 Bêta =0,370 et p=0,00001). Conclusion Les meilleurs prédicateurs du succès en première année étaient une bonne moyenne en sciences physiques au BAC et une mention bien. La prise en compte de ces éléments dans le recrutement des étudiants en première année pourrait améliorer les résultats académiques. PMID:27313819

    At the Canadian Health Services Research Foundation we talk a lot about the need to improve the 'receptor capacity' for research in the health sector (Canadian Health Services Research Foundation 2000). To create a demand for research as well as a supply of it. To encourage and assist clinicians, managers and policymakers in the health system to pull research from academe with as much fervor as applied researchers now bring to publishing it. Browman, Snider and Ellis have done more than talk about and encourage these things - they have implemented them at their own workplace in Hamilton. Their formula is:1. Design a policy-learning forum (Clinical Policy Committee'), where the use of available research is encouraged and expected 2. Create champions (knowledge stewards') responsible for marshalling and presenting the evidence. 3. Provide rules (negotiation') for the dialogue between the operational implications of the research and its budgetary reality. 4. Use story telling to uncover local implementation barriers and make tacit knowledge explicit. The approach is reminiscent of political scientist Paul Sabatier's description of the circumstances under which policy learning occurs (Sabatier and Jenkins-Smith 1993) and Brown and Duguid's compelling outline of how information permeates corporate structures (Brown and Duguid 2000). Sabatiers advocacy coalition framework highlights the optimal conditions for learning as: balanced coalitions (in this case, of those behind the research and those behind the finances), enough resources for each side to produce a steady flow of information, an organized forum for debate and clear rules of engagement. In 'The Social Life of Information, 'Brown and Duguid highlight the extent to which modern corporations often leave unrecognized and under-utilized their greatest asset - the tacit knowledge accumulated by each employee over his or her career. They, too, recommend storytelling as a way to liberate this knowledge for wider use

La présente étude objective de déterminer la prévalence et les caractéristiques dans le campus Universitaire Kasapa de l'Université de Lubumbashi. Méthodes L'interview indirecte a servi à la collecte des données qui ont été traitées par le logiciel Graphpad version 5. Résultats De 515 étudiants consultés, l'automédication présente une prévalence de 99%, une partie des sujets l'ayant débutée à l'adolescence (35%). Des répondants, 78,8% reconnaissent que l'automédication peut conduire à un échec thérapeutique et que des erreurs de dose, un traitement inadapté, des effets secondaires et des erreurs diagnostiques sont plausibles. Cette pratique est acceptée pour autant qu'elle permette de prendre en charge des maladies ou symptômes présumés bénins et connus avec pour avantages, discrétion et économie de temps et d'argent. La malaria (82,4%), la fièvre (65,5%), les maux de tête (65,5%) en constituent les trois premières causes. L'amoxicilline (98,2%), le paracétamol (97,5%), l'acide ascorbique (91,6%) et la quinine (79,4%) sont les quatre premiers médicaments les plus consommés. L'association la plus utilisée est paracétamol’ vitamine(s) (88,8%) et la plus aberrante amoxycilline -Erytromycine (25,5%). Le comprimé (37%) constitue la forme la plus utilisée. La plupart des sujets (84,9%), recourent aux plantes médicinales. Conclusion Dans ce milieu, il existe une forte prévalence de l'automédication largement dans un but antipalustre avec quelques abus.

    Against a background of agitated discussion, the author analyzes the significance of new information and communication technologies for research and teaching at the university level. With reference to the concept of discovery learning ( forschendes Lernen) which gained significance in the Federal Republic of Germany in conjunction with university reforms after 1968, this article analyzes the consequences that the use of new media has for research, teaching and service/administration. The author concludes that possible structural changes can perhaps be observed in the service sector but that the basic tasks of research and teaching are hardly being affected by the new media. The creative questioning and reflection of researchers as well as the responsibility of those who teach remain irreplaceable.

    The large number of secondary school graduates entering higher education is transforming the nature of universities, particularly in literature and the humanities, by changing the relative numbers of students enrolled in different academic years. At the same time this influx is accompanied by a significant failure rate in the first academic year, calling into question the efficacy of the university system. A national issue with local repercussions, the struggle against failure in the first year is leading to much heart-searching among the universities, whose staff are trying hard to understand why certain students abandon their studies. The enquiry described in this article reveals the co-existence of two student populations: those who enter university as an active choice and those who do so by default. In the case of the first group, entry to university represents an investment for the future which must be carefully managed. In the second case it is a matter of going into higher education as a faute de mieux solution in an economic context in which work is scarce.

    This essay examines the lives of five great scientists who contributed enormously to mankind. Although their lives were vastly different, they all trod a final common pathway in securing scientific breakthroughs. These were stubborn, egotistical, tenacious, work-oriented people who could not be deterred by obstacles of any sort. They exemplify the unbreakable spirit required to achieve greatness. A surprising finding is the extent of hostility they all aroused from closed-minded people in society who were upset by the implications of their new ideas. It is hoped that this essay will help to stiffen the resolve of creative men and women who can expect to confront fervent opposition from others in society regardless of the value of their discoveries.

    2001-01-01

    In this HBR interview, CEO Michael Ruettgers speaks in detail about the managerial practices that have allowed EMC to anticipate and exploit disruptive technologies, market opportunities, and business models ahead of its competitors. He recounts how the company repeatedly ventured into untested markets, ultimately transforming itself from a struggling maker of minicomputer memory boards into a data storage powerhouse and one of the most successful companies of the past decade. The company has achieved sustained and nearly unrivaled revenue, profit, and shareprice growth through a number of means. Emphasizing timing and speed, Ruettgers says, is critical. That's meant staggering products rather than developing them sequentially and avoiding the excessive refinements that slow time to market. Indeed, a sense of urgency, Ruettgers explains, has been critical to EMC's success. Processes such as quarterly goal setting and monthly forecasting meetings help maintain a sense of urgency and allow managers to get early glimpses of changes in the market. So does an environment in which personal accountability is stressed and the corporate focus is single-minded. Perhaps most important, the company has procedures to glean insights from customers. Intensive forums involving EMC engineers and leading-edge customers, who typically push for unconventional solutions to their problems, often yield new product features. Similarly, a customer service system that includes real-time monitoring of product use enables EMC to understand customer needs firsthand. PMID:11189457

  15. Paul Weiss and the genesis of canonical quantization

    NASA Astrophysics Data System (ADS)

    Rickles, Dean; Blum, Alexander

    2015-12-01

    This paper describes the life and work of a figure who, we argue, was of primary importance during the early years of field quantisation and (albeit more indirectly) quantum gravity. A student of Dirac and Born, he was interned in Canada during the second world war as an enemy alien and after his release never seemed to regain a good foothold in physics, identifying thereafter as a mathematician. He developed a general method of quantizing (linear and non-linear) field theories based on the parameters labelling an arbitrary hypersurface. This method (the `parameter formalism' often attributed to Dirac), though later discarded, was employed (and viewed at the time as an extremely important tool) by the leading figures associated with canonical quantum gravity: Dirac, Pirani and Schild, Bergmann, DeWitt, and others. We argue that he deserves wider recognition for this and other innovations.

  16. Fundamentals of Electroanalytical Chemistry (by Paul M. S. Monk)

    Langhus, David L.

    2002-10-01

    While it's conceivable that this book could be used as a text in an undergraduate course involving electroanalytical chemistry, its shallow treatment and unusual presentation make it awkward for that purpose. Similarly, it is probably not ideal as a general reference, although the handful of citations of current books and review articles on aspects of electrochemistry might serve to point one toward more comprehensive treatments. In all fairness, the author alerts us to this possibility up front. On the other hand, for the student who needs to become conversant in electroanalytical methods without benefit of a formal course (for example, if he or she wished to attempt an undergraduate research project involving an electrochemical method prior to being qualified to enroll in an instrumental analysis course) the traditional offerings are typically either narrowly focused or overwhelming for self-study by all but the most stalwart neophyte. This book provides a compact and reader-friendly treatment that makes modest demands in terms of preparation, yet leaves the reader with a broad, if not particularly deep, foundation of understanding to which may then be added the details particular to the matter at hand.

    The goal of this paper is to provide an interpretation of Feyerabend's metaphysics of science as found in late works like Conquest of Abundance and Tyranny of Science. Feyerabend's late metaphysics consists of an attempt to criticize and provide a systematic alternative to traditional scientific realism, a package of views he sometimes referred to as "scientific materialism." Scientific materialism is objectionable not only on metaphysical grounds, nor because it provides a poor ground for understanding science, but because it implies problematic claims about the epistemic and cultural authority of science, claims incompatible with situating science properly in democratic societies. I show how Feyerabend's metaphysical view, which I call "the abundant world" or "abundant realism," constitute a sophisticated and challenging form of ontological pluralism that makes interesting connections with contemporary philosophy of science and issues of the political and policy role of science in a democratic society.

    The question of the status of cause-and-effect explanations of human behavior that posit physically existing causative factors and those that, on the other hand, posit hypothetical entities in the form of "useful fictions" has a long history. The influence of the works of Jeremy Bentham and Hans Vaihinger, as well as the later influence of Francis Galton, is described. Issues of the validity of hypothetical constructs and related problems of measurement and definition as found in psychoanalytic theory construction and in trait theory are examined. The significant and continuing interest generated by the landmark studies of K. MacCorquodale and P. E. Meehl (1948) and L. J. Cronbach and P. E. Meehl (1955) as well as the central importance of P. E. Meehl's thinking are described. PMID:16393008

  7. Landscape by Moonlight: Peter Paul Rubens and Astronomy

    In the last years of his life, Rubens (1577-1640) lived happily with his wife and children on his Het Steen estate. During this period he worked and reworked a painting that had special meaning to him—Landscape by Moonlight (1635-40), now at the Courtauld Gallery in London. After a highly successful career painting religious and secular portraits, allegories, and occasional landscapes, Rubens put an extraordinary amount of effort into this final landscape. He was well known as a person who would commit to memory ideas and themes that he would use in future works. This paper reviews Rubens' attention to the visualization of nature, his personal connections to Elsheimer, Galileo, and Peiresc, and explores his possible depiction of constellations recalled from memory and placed within the cloudy skies in his Landscape by Moonlight.

Los mismos estaban destinados a servir como herramientas de enseñanza. 62% de los 106 ensayos de 55 estudiantes obtuvo grados A, B o C. 21% de los 47 encuestados que respondieron al cuestionario posterior consideró que los ensayos aumentaron su interés por la astronomía. 49% de los encuestados consideró que los ensayos no eran educacionalmente útiles y que no deben ser propuestos de nuevo. Las respuestas escritas más comunes a nuestra encuesta indicaran que los estudiantes necesitan más orientación y una mejor preparación en la redacción de ensayos exitosos. Dado que los estudiantes encontraron las piezas conceptuales de los ensayos difíciles, en el futuro vamos a ofrecer actividades pertinentes antes de los plazos de redacción para ayudar a los estudiantes a crear ensayos de mayor calidad. Nós ocasionalmente incluímos projetos em nosso curso universitário introdutório centrado no aluno para permitir aos estudantes que pertencem às carreiras não científicas explorar alguns conceitos astronômicos em mais detalhes do que o normal. Tais projetos também enfatizam eventos astronômicos em curso ou futuros. Esperamos que os alunos se sintam mais interessados na astronomia através de projetos ligados a eventos astronômicos. No termo de Primavera de 2012 (EUA), propomos ensaios curtos focados em eclipses, trânsitos e ocultações para promover o raro trânsito de Vênus que ocorreu no dia 5 de junho de 2012.

    This concise history of Munich Observatory, written by a staff member, is actually the second, enlarged and updated edition of a brochure that was based on a pair of articles in the now defunct journal Die Sterne (Vol. 68, 263 and 340, 1992). First attempts to establish an observatory in Munich date back to 1759, when the Bavarian Academy of Sciences was founded and a topographic survey was begun; but these private attempts did not lead to a permanent installation. A more official interest arose when a topographic bureau was opened under French direction in 1801, and when the prince-elect Max IV Joseph planned a new land tax which required precise mapping. The collapse of the French rule also meant a collapse of the plans for the new observatory. In 1816, however, things began to develop with an unprecedented speed. The astronomer and surveyor Johann Georg von Soldner was appointed to become observatory director, and king Max I Joseph gave the order to erect the new observatory, which was completed near the end of 1817. The location was chosen near the the village of Bogenhausen (now a suburb of Munich). It took a little longer to install the instrumentation; first observations started in early 1819. Soldner's circle of friends comprised local instrument makers, including Fraunhofer and Reichenbach. With the former, he completed a new apparatus for experiments on the nature of the light of the fixed stars, a refractor of 10 cm aperture equipped with an objective prism. The study of sunlight, began by Fraunhofer, was now extended to the light of planets and fixed stars. Soldner also started a continuous meteorological record. But his name will always be remembered in the annals of science because of a short note, published in 1801 when he was still a student of Bode in Berlin, his On the deviation of a light ray from its rectilinear motion by the attraction of a celestial body which it passes at short distance. Soldner's last years were darkened by illness and enmities. Unfortunately the book does not tell anything about the notorious lunar observer Franz von Paula Gruithuisen, who was appointed professor of astronomy at Munich University in 1826. Soldner died in 1833, and his position was taken by Johann von Lamont, who did pioneering astrometric measurements of Halley's comet, took up again Fraunhofer's and Soldners studies of stellar spectra, but then felt that he should concentrate on only a few studies (stellar positions, magnetic and meteorological measurements). In addition he installed a mechanical workshop in the observatory, where many of the instruments were built, and which exists till the present day. After his death, a three-year vacancy of the director's chair was filled by the mathematician Ludwig Seidel. This was followed by the long reign of Hugo von Seeliger, beginning in 1882 and only ending in 1924. He is most famous for his studies in stellar statistics and other theoretical fields, but he was also active in observational work, including the timeservice. The following 25 years saw two less known directors, Alexander Wilkens and Wilhelm Rabe. After the latter's dismissal, Erich Schoenberg, a theoretician from Breslau, took over in 1949. Numerous changes had happened since Seeliger's time: the integration of a private solar observatory in Herrsching in 1932, which was dissolved in 1946, the transformation into a ``University Observatory'' in 1937/8, major damages through air raids in 1944, and finally, in 1949, the integration of the Wendelstein Solar Observatory, founded by the Deutsche Versuchsanstalt für Luftfahrt in 1941, as one of a series of stations to monitor solar activity. Schoenberg's retirement in 1955 was followed by an interim time of six years. In the following 21 years, Peter Wellmann re-shaped the observatory by building a research group on stellar atmospheres, one of the fields in which the observatory still excels. In the era of Rolf Kudritzki (1982 - 1998), these studies were further pursued and extended. An overview of the Observatory's actual research fields, research installations, its development of modern instrumentation, as well as its activities in public outreach (dating back to TV programmes by R. Kühn in the 1950s which the reviewer still vividly recalls) conclude this historic overview. The appendix lists the Observatory's publication series, statistics of recent publications and their impact, as well as post statistics of the institute - the booklet may also have been written to serve as a lobbying tool for governmental and private sponsorship. Häfner has succeeded in writing a concise sketch of the history of a an important German astronomical institution. It contains a lot of citations from original sources, printed in italics (without indicating their exact locations - this is understandable since Häfner did not want to write an ``academic'' article full of references and footnotes), as well as a useful bibliography.

    The present study attempted to identify critical symptom domains of individuals with Myalgic Encephalomyelitis (ME) and chronic fatigue syndrome (CFS). Using patient and control samples collected in the United States, Great Britain, and Norway, exploratory factor analysis (EFA) was used to establish the underlying factor structure of ME and CFS symptoms. The EFA suggested a four-factor solution: post-exertional malaise, cognitive dysfunction, sleep difficulties, and a combined factor consisting of neuroendocrine, autonomic, and immune dysfunction symptoms. The use of empirical methods could help better understand the fundamental symptom domains of this illness. PMID:27088131

    A single ion immersed in a neutral buffer gas is studied. An analytical model is developed that gives a complete description of the dynamics and steady-state properties of the ions. An extension of this model, using techniques employed in the mathematics of economics and finance, is used to explain the recent observation of non-Maxwellian statistics for these systems. Taken together, these results offer an explanation of the long-standing issues associated with sympathetic cooling of an ion by a neutral buffer gas. PMID:24765957
