    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

    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

    The symbols k and q denote wave numbers in scattering experiments as well as in NMR imaging. 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.

    PubMed

    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.

    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

    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.

    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).

    PubMed Central

    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.

    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

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

    PubMed

    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

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

    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.

  10. Paul de Kruif's Microbe Hunters and an outraged Ronald Ross.

    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.

    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

    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

    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.

    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.

    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

  3. 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 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

    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.

    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

    2016-08-16

    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.

  6. 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.

  14. 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.

  16. Metapsychology or metapsychologies? Some comments on Paul Denis's paper 'The drive revisited: mastery and satisfaction'.

    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.

  17. 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

  18. 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.

  19. Experimental study on dipole motion of an ion plasma confined in a linear Paul trap

    NASA Astrophysics Data System (ADS)

    Ito, K.; Okano, T.; Moriya, K.; Fukushima, K.; Higaki, H.; Okamoto, H.

    2015-11-01

    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.

    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 biography of Paul Rosenstein (1875-1964) serves as an example of the fate of a Jewish scientist at the beginning of the twentieth century in an area of conflict between the development of urology as a specialty at greater urban hospitals, professional achievements as a surgeon and scientist, drastic breaks during Nazi era and escape from Nazi terror via New York to Brazil.

    Maurice Victor, the great Canadian neurologist, was an expert on the neurology of alcoholism including the Wernicke-Korsakoff syndrome. In Boston, Massachusetts he encountered the leading neuroanatomist, Paul Yakovlev, an immigrant from Russia. Together Victor and Yakovlev collaborated on translating the work of S.S. Korsakoff from Russian to English. This interview of Victor about Yakovlev is informative about both of these great figures in North American Neurology. PMID:19534330

    The first published paper by a professional, research astronomer which discussed airborne astronomy from airplanes was by Paul W. Merrill. In it he proposed some of the types of observations which might be made, looking up at astronomical objects in the sky. This paper describes Merrill's paper, his education, training and subsequent career, and a few other aspects of the early history of airborne astronomy.

    This paper has examined the relationship between the life and the thought of Jean-Paul Sartre. 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.

  10. Universal, non-monotonic structure in the saturation curves of a linear Paul trap

    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.
