Decentralized control of large-scale systems: Fixed modes, sensitivity and parametric robustness. Ph.D. Thesis - Universite Paul Sabatier, 1985  

NASA Technical Reports Server (NTRS)

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.

Sabatier Catalyst Poisoning Investigation  

NASA Technical Reports Server (NTRS)

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.

Sabatier Methanation Reactor for Space Exploration  

NASA Technical Reports Server (NTRS)

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 adequately addressing these issues will be presented. The Sabatier carbon dioxide reduction process will greatly benefit any of the extended duration human exploration missions because of the tremendous savings of consumables realized. Any of these mission scenarios, be they transit or surface based, must consider closing the life support loops in order to make the mission achievable, let alone affordable. Carbon dioxide reduction technology will be necessary for future outpost habitats, and the technology needs to be proven viable in a space application. The Sabatier methanation reaction is also a desirable method for producing propellant from the Mars atmosphere. The common system could be designed to accept carbon dioxide from an indoor air revitalization loop concentrator, or from an outdoor atmosphere compressor. Carbon dioxide reduction validation is but one step in the spiral development of the in-situ propellant production system desired for future planetary exploration.

Highly Stable and Active Catalyst for Sabatier Reactions  

NASA Technical Reports Server (NTRS)

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.

Compact and Lightweight Sabatier Reactor for Carbon Dioxide Reduction  

NASA Technical Reports Server (NTRS)

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 study of the Sabatier-methanation reaction kinetics  

NASA Technical Reports Server (NTRS)

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.

Sabatier Carbon Dioxide Reduction Assembly Development for Closed Loop Water Recovery  

NASA Technical Reports Server (NTRS)

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 and had a successful technical review by the NASA Safety Board. The current focus is now related to development of the water/methane phase separator, liquid sensor and CO2 compressor piston seal life. The overall goal of the current effort is to bring the system up to a TRL6 by the end of GFY04. Although the Sabatier CRA is not currently baselined for use on the ISS, its benefits are significant enough such that volume within the Oxygen Generation System rack has been reserved for future installation. The value of the water the CRA recover will allow NASA the additional crew time and payload needed to pursue its mission of scientific research.

Integrated Testing of a 4-Bed Molecular Sieve, Air-Cooled Temperature Swing Adsorption Compressor, and Sabatier Engineering Development Unit  

NASA Technical Reports Server (NTRS)

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.

Compact, Lightweight Adsorber and Sabatier Reactor for CO2 Capture and Reduction for Consumable and Propellant Production  

NASA Technical Reports Server (NTRS)

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.

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

NASA Technical Reports Server (NTRS)

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.

Paul Trap Simulator Experiment  

NASA Astrophysics Data System (ADS)

The Paul Trap Simulator Experiment (PTSX) is a compact laboratory facility whose purpose is to simulate the nonlinear dynamics of intense charged particle beam propagation over a large distance through an alternating-gradient transport system. The simulation is possible because the quadrupole electric fields of the cylindrical Paul trap exert radial forces on the charged particles that are analogous to the radial forces that a periodic focusing quadrupole magnetic field exert on the beam particles in the beam frame. By controlling the waveform applied to the walls of the trap, PTSX will explore physics issues such as beam mismatch, envelope instabilities, halo particle production, compression techniques, collective wave excitations, and beam profile effects. Initial experiments have concentrated on characterizing the cesium ion source and studying ``free-steaming" ions that travel directly from the ion source to the Faraday cup diagnostic. The aluminosilicate cesium source provides up to 30 ?A, which is greater than the estimated 300 pA required to load the trap to a density of 10^6 cm-3. Variation of the wall voltage and the oscillation frequency reveals the stability limit of the single particle orbits.

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

NASA Technical Reports Server (NTRS)

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.

Ron Paul + Potheads = Racist Dopes

Ron Paul’s popularity, given his history of racism, is troubling. More troubling, however, is the willingness of his supporters, an odd coalition of one-percenter corporatists and anti-war pothead libertarians, to ignore or excuse these views.

Paul Gauguin in Brittany  

NASA Astrophysics Data System (ADS)

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.

The EY Exhibition: Paul Klee  

NSDL National Science Digital Library

"Paul Klee â Making Visible" at the Tate Modern in London is the first exhibition to be put on as a result of the Tate's partnership with financial giant, EY. Two more major exhibitions are planned over the next two years. The show at the Tate ran October 16, 2013 - March 9, 2014, but visitors to the website can still enjoy online features such as the blog, Paul Klee A - Z, written by curator Matthew Gale. In the post C is for Cat, Klee tells artists what to do when a cat runs across their work. In 1931, when an American collector, Edward M.M. Warburg, visited Klee's studio, a cat started to run across a still-wet water color, alarming Warburg. Klee said to let the cat walk where it wanted, because, âÂÂMany years from now, one of you art connoisseurs will wonder how in the world I ever got that effect.â Gale links to the full story related in an issue of the Tate, Etc. newsletter from fall, 2013, by Nicholas Fox-Weber. Other blog posts, not part of the A - Z series, provide a behind the scene look at the process of installing the exhibition (October 9, 2013) and Klee's rules of Bauhaus. There's also a 4 minute video that provides an overview of the show with Matthew Gale.

Major Additions to the Linus Pauling Canon  

NASA Astrophysics Data System (ADS)

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.

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

NASA Technical Reports Server (NTRS)

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

Obituary: Damon Paul Simonelli, 1959-2004  

NASA Astrophysics Data System (ADS)

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 quantitative radiative transfer models to understand the physical character of planetary surfaces. He also became interested in post-eclipse brightening on the Galilean satellite Io, a phenomenon that was purported to be due to the condensation of the satellite's tenuous atmosphere during an eclipse by Jupiter. He carefully and skeptically studied this phenomenon, as well as the related problem of night time atmospheric condensation. His thesis was on the microphysical nature and thermal properties of Io's surface. He graduated with a PhD in Astronomy and Space Sciences from Cornell in 1987. Damon took on a new scientific challenge when he accepted a National Research Council Fellowship at NASA Ames Research Center with Jim Pollack. He worked with Pollack, Ray Reynolds, and Chris McKay on the interior structure of the Pluto/Charon system, and the carbon budget in the outer Solar System. Using new data on the density of Pluto derived from mutual events, Damon led a team that maintained the rockier composition of Pluto implied it formed in a CO-rich outer solar nebula rather than in a circumplanetary nebula. A paper by Simonelli and Reynolds suggested the possibility that Pluto was dense because it had lost its volatiles during an impact event that formed Charon, a suggestion that was later validated by Robin Canup's work. At the time of his death, Damon was a collaborator on the New Horizons Mission to Pluto, due to be launched in early 2006. Damon returned to Cornell in 1991 to embark on a third scientific career. With Veverka, Peter Thomas, and Paul Helfenstein, he led a team to study the nature of the small, formerly uninteresting bodies of the Solar System, including the inner satellites of Jupiter that were imaged by the Galileo camera. He applied Thomas's "spud" shape model and Helfenstein's Hapke model to derive the shapes, roughness, albedo, and surface texture of a wide range of small bodies, including Io, Phobos, Phoebe, the asteroids Gaspra and Ida, and Europa. Damon also became an expert at planning spacecraft observations and command sequences for G

In Memoriam: Paul M. Kintner Jr. (1946-2010)  

NASA Astrophysics Data System (ADS)

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).

Paul Klee's illness (systemic sclerosis) and artistic transfiguration.  

PubMed

Klee's symptoms, and the rapid progression of the illness, ending with his death after only 5 years, in all probability indicate the rarest but most serious form of scleroderma, known as diffuse systemic sclerosis. Although his skin and internal organs were heavily stricken by the illness, the artist's hands were fortunately spared. Thus he was able to draw and paint without hindrance to the end. Classified amongst diseases of the autoimmunity system, this form of sclerosis often has inexplicable causes. I believe, however, that the defamations suffered by Klee, his dismissal as professor of the Art Academy in Düsseldorf by the National Socialists, and the unintended isolation after his return to Berne were causative factors in the outbreak of the illness. Mentally and spiritually, the artist rose above his heavy bodily suffering. Constantly, his creativity remained vigorous. Although the greater part of Klee's works in his last years cannot be linked directly with his illness, careful viewing reveals a significant preoccupation with fate and illness. It is above all in his drawings, that were created like a diary, that the sorrows and troubles of the ill artist emerge: his fears, but also his hopes and finally his resignation to the illness, and his readiness for death. In undesired isolation, and in his own spiritual world, Paul Klee created with exemplary concentration, discipline and diligence a considerable number of late works, which differ from his early work and which deserve our full admiration. Reserved, quiet and kind, Paul Klee was nevertheless charismatic. And his art is poetic. Possessing a special aura, it can enchant those who surrender to it without any prejudice. Paul Klee has created an oeuvre that is unique, reflecting his character closely: a body of work that moves and stirs us by its deep humanity. PMID:20375519

Cooling charged particles in a Paul trap by feedback control  

NASA Astrophysics Data System (ADS)

A method to cool particles in a Paul trap without a laser is presented and simulated numerically. By adjusting the electric potential applied to electrodes as the feedback, an effect similar to that of laser cooling can be achieved. Results show that feedback control, with or without delay, continuously or discretely, and with or without noise, can effectively reduce kinetic energy and lead the system to a low periodic orbit over a wide range of control intensity. The final orbit of the controlled system is near to an elliptic orbit of the uncontrolled system and the system maintains regular motion when control is withdrawn.

Acoustic Coupling Effects in ST Paul's Cathedral, London  

NASA Astrophysics Data System (ADS)

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.

NASA Astrophysics Data System (ADS)

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.

Specificity in Transition State Binding: The Pauling Model Revisited  

PubMed Central

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 ?-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 with the free enzyme. Evidence is presented that supports a model in which the binding energy of the phosphite dianion piece, or the phosphodianion group of the whole substrate, is utilized to drive an enzyme conformational change from an inactive open form EO to an active closed form EC, by closure of a phosphodianion gripper loop. Members of the enolase and haloalkanoic acid dehalogenase superfamilies use variable capping domains to interact with nonreacting portions of the substrate and sequester the substrate from interaction with bulk solvent. Interactions of this capping domain with the phenyl group of mandelate have been shown to activate mandelate racemase for catalysis of deprotonation of ?-carbonyl carbon. We propose that an important function of these capping domains is to utilize the binding interactions with nonreacting portions of the substrate to activate the enzyme for catalysis.

Cryogenic linear Paul trap for cold highly charged ion experiments.  

PubMed

Storage and cooling of highly charged ions require ultra-high vacuum levels obtainable by means of cryogenic methods. We have developed a linear Paul trap operating at 4 K capable of very long ion storage times of about 30 h. A conservative upper bound of the H(2) partial pressure of about 10(-15) mbar (at 4 K) is obtained from this. External ion injection is possible and optimized optical access for lasers is provided, while exposure to black body radiation is minimized. First results of its operation with atomic and molecular ions are presented. An all-solid state laser system at 313 nm has been set up to provide cold Be(+) ions for sympathetic cooling of highly charged ions. PMID:22938282

[Scleroderma and Paul Klee: Metamorphosis of life and art?].  

PubMed

Paul Klee was born in 1879 in Münchenbuchsee, not far from Bern, and died at the age of 60 in Switzerland due to severe scleroderma, which was diagnosed in 1936. From this time on, this connective tissue disease had followed him continuously and had strongly influenced his enjoyment of life, personal development and creative power in art work, before finally causing his death in 1940. Based on diaries, letters, personal remarks and notes, his case history was reconstructed from the first symptoms to the date of diagnosis up until his death and an analysis was made of the influence his illness had on his art work in aura, color, figure and productivity.

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

PubMed

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.

Paul Revere Collection at the American Antiquarian Society  

NSDL National Science Digital Library

Yes, it is true that Paul Revere did once take a horse on a very well known ride across the landscape of eastern Massachusetts. But he did many other things, including spending time as a dentist, an engraver, a printer, and also finding time to make exquisite silverware. This remarkable digital collection from the American Antiquarian Society (AAS) brings together an illustrated inventory of Revere's work documented and researched by former AAS president, Clarence S. Brigham. This collection of engravings, published prints, and currency allows users to explore by subject or even conduct a search using a thumbnail gallery. The Subject-Tag Browse feature is a real pip, and users can click on terms such as "animal", "Chippendale style", and "Buildings and structures." This last area is a great place to start, as it features images of Harvard College, the landing of British troops in Boston, and an illustration of a hemp mill.

[Paul Nitsche: psychiatric reformer and main protagonist of Nazi euthanasia].  

PubMed

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

STS-102 Astronaut Paul Richards Participates in Space Walk  

NASA Technical Reports Server (NTRS)

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.

One More Legacy of Paul F. Brandwein: Creating Scientists  

NASA Astrophysics Data System (ADS)

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).

Study of nonlinear resonance effect in Paul trap.  

PubMed

In this article, we investigated the nonlinear resonance effect in the Paul trap with a superimposed hexapole field, which was assumed as a perturbation to the quadrupole field. On the basis of the Poincare-Lighthill-Kuo (PLK) perturbation method, ion motional equation, known as nonlinear Mathieu equation (NME) was expressed as the addition of approximation equations in terms of perturbation order. We discussed the frequency characteristics of ion axial-radial (z-r) coupled motion in the nonlinear field, derived the expressions of ion trajectories and nonlinear resonance conditions, and found that the mechanism of nonlinear resonance is similar to the normal resonance. The frequency spectrum of ion motion in nonlinear field includes not only the natural frequency series but also nonlinear introduced frequency series, which provide the driving force for the nonlinear resonance. The nonlinear field and the nonlinear effects are inevitable in practical ion trap experiments. Our method provides better understanding of these nonlinear effects and would be helpful for the instrumentation for ion trap mass spectrometers. PMID:23504643

PubMed

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.

Amsterdam-St. Paul Hotspot: Composition, Motion and History  

NASA Astrophysics Data System (ADS)

The Amsterdam-St Paul (ASP) plateau results of the excess of melting induced by the interaction between the ASP hotspot and the South-East Indian Ridge. The ASP plume was originally located beneath the Australian Plate and its interaction with the SEIR began about 10 Ma ago. This location provides an unique opportunity to study the hotspot prior to its interaction with the SEIR and its chemical and physical evolution. An exhaustive study of the hotspot characteristics prior to its interaction lead to know its geochemical compositions. The geochemistry of its interaction with the SEIR (i. e. ASP plateau) provides indirect information on the regional Indian Ocean upper mantle. ASP plume has a moderately enriched composition with resulting seamount melts having 2.5 < (La/Sm)C1norm < 2.8. In addition isotope ratios are not as extreme as estimated in previous works [Doucet et al. 2004; Nicolaysen et al., 2007] with 86Sr/87Sr ? 0.7040, 143Nd/144Nd ? 0.5128, 206Pb/204Pb ? 19.0 and 208Pb/204Pb ? 39.2. The ASP plateau isotopic composition reveals that the Indian Ocean upper mantle is extremely heterogeneous. It was proposed that the ridge segments across the plateau have interacted 40 My ago with Kerguelen plume [Frey et al. 2000]. We therefore assume that some plume material has been left behind in the Indian Ocean upper mantle during the movement of the Australian plate above it. Consequently, the upper mantle in the area might be a good example of 'marble cake' [Allegre&Turcotte, 1986]. When the SEIR approaches the ASP hotspot, plume derived material mixes with the surrounded mantle leading to the complexity seen in ASP plateau materials. K-Ar datings reveal that the absolute motion of the Australian plate calculated with respect to the fixity of ASP plume is of about 77 km/My. With a spreading rate of about 6-7 cm/yr the accretion at the SEIR axis cannot account for this velocity. In consequence, an absolute motion of the ASP plume of about 10-20km/My, comparable to that of Hawaii [Tarduno et al. 2003], could account for this discrepancy. References: Allegre & Turcotte.

[PAUL procedure. A new biocompatible concept for the therapy of congenital abdominal wall defects].  

PubMed

Treatment of small congenital abdominal wall defects (e.g. omphalocele and gastroschisis) can be performed by direct closure. In large defects non-resorbable artificial materials (e.g. Gore-Tex) are necessary to close the fascia. The aim of this study was to find out whether a new procedure, the PAUL pocedure, might be suitable for the treatment of large abdominal wall defects. A full thickness abdominal wall defect was created in young Wistar Rats. These defects were then closed by implantation of a 1x2 cm sized piece of PTFE (Dual-Mesh), a polypropylene mesh (Prolene(R)) or by using the PAUL procedure. Over a period of 6 weeks no wound infections or hernias were monitored. In contrast to PTFE the PAUL procedure showed only minimal adhesion to the intestine and a high stability of the implanted material. A xenogenic extracellular matrix, such as that used in the PAUL procedure, may induce an immune response, which is comparable with a remodeling reaction rather than rejection. Based on these good results a large animal model study (Goettinger mini-piglets) was performed. No wound infections or hernias could be observed throughout the experiment. Control laparoscopy after 3, 6, 9, and 12 months showed only minimal adhesion to the intestine. Our results indicate that the PAUL procedure can be used easily and successfully for the therapy of congenital abdominal wall defects. PMID:19756429

Brotherly Advice: Letters from Hugo to Paul Ehrenfest in his Final Years  

NASA Astrophysics Data System (ADS)

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.

In a tetrahedron based NLC, the first order gives the Pauling residual entropy of (1)/(2)ln(3)/(2)?0.20273. A 16th order NLC calculation changes the residual entropy to 0.205507, a correction of 1.37% over the Pauling value. At high temperatures, the accuracy of the calculations is verified by a high temperature series expansion. We find the corrections to the single tetrahedron approximations to be at most a few percent for all the thermodynamic properties.

Asymptotic solution of Fokker-Planck equation for plasma in Paul traps  

NASA Astrophysics Data System (ADS)

An exact analytic solution of the Vlasov equation for the plasma distribution in a Paul trap is known to be a Maxwellian and thus, immune to collisions under the assumption of infinitely fast relaxation [K. Shah and H. S. Ramachandran, Phys. Plasmas 15, 062303 (2008)]. In this paper, it is shown that even for a more realistic situation of finite time relaxation, solutions of the Fokker-Planck equation lead to an equilibrium solution of the form of a Maxwellian with oscillatory temperature. This shows that the rf heating observed in Paul traps cannot be caused due to collisional effects alone.

Case Report on the Illness of Paul Klee (1879-1940)  

PubMed Central

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.

The Paul wavelet algorithm: an alternative approach to calculate the refractive index dispersion of a dielectric film from transmittance spectrum  

NASA Astrophysics Data System (ADS)

A new application of the Paul wavelet algorithm was presented to determine the refractive index dispersion of a dielectric film from transmittance spectrum in the visible and near infrared region. The developed algorithm was tested by simulated data and experimentally applied to a sample of mica. The obtained refractive index dispersion determined by the Paul wavelet algorithm was compared with the refractive index values determined by the envelope and fringe counting methods, and also with the established result. It was shown that the degree of the Paul wavelet has a major effect on the outcome of a refractive index determination. The noise immunity of the presented method was shown by the simulation study.

Direct and Beat-Wave Excitation of Collective Beam Modes in the Paul Trap Simulator Experiment  

NASA Astrophysics Data System (ADS)

The Paul Trap Simulator Experiment (PTSX) is a cylindrical Paul trap that simulates a long, thin charge bunch propagating through an equivalent kilometers-long magnetic alternating-gradient (AG) transport system. An external quadrupole drive is applied to excite collective modes, and experiments on PTSX show that when the charge bunch is driven either directly at the mode frequencies, or indirectly, using beat-wave excitation, the properties and dynamics of the charge bunch are strongly affected. Results are presented from experiments in which the drive amplitude, frequency, and drive duration are varied. The experimental data are compared with results of particle-in-cell (PIC) simulations performed using the WARP particle-in-cell (PIC) code.

Measurement of isotope ratios of Calcium is very useful in many fields. So we demonstrated the measurement of isotope ratios of {sup 40}Ca{sup +}(abundance 96.4%) to {sup 44}Ca{sup +}(2.09%) ions in a linear Paul trap with several laser lights tuning to the isotope shifts. And we found that the experimental parameters had large influences on the measurement of the isotope ratios.

Surface-electrode Paul trap with optimized near-field microwave control  

NASA Astrophysics Data System (ADS)

We describe the design of a microfabricated Paul trap with integrated microwave conductors for quantum simulation and entangling logic gates. We focus on an approach where near-field amplitude gradients of microwave fields from conductors in the trap structure induce the required spin-motional couplings. This necessitates a strong amplitude gradient of the microwave near-field at the position of the ions, while the field itself needs to be suppressed as much as possible. We introduce a single meander-like microwave conductor structure which provides the desired field configuration. We optimize its parameters through full-wave microwave numerical simulations of the near-fields. The microwave conductor is integrated with additional dc and rf electrodes to form the actual Paul trap. We discuss the influence of the additional electrodes on the field configuration. To be able to fine-tune the overlap of the Paul trap rf null with the microwave field minimum, our trap design allows relative tuning of trap rf electrode amplitudes. Our optimized geometry could achieve a ratio of sideband-to-carrier excitations comparable to experiments with focused laser beams.

The death of John Paul Jones and resurrection as 'father of the US Navy'.  

PubMed

John Paul Jones, 'father of the US Navy', died under mysterious circumstances on July 18, 1792. Although his remains were resurrected and autopsied 113 years later, the cause of his death has yet to be explained fully. In this detailed review of his clinical history and autopsy findings, we conclude, as have others, that Jones died of kidney failure of undermined etiology. Although 'interstitial nephritis' was diagnosed by the prosectors who performed his autopsy, we believe glomerulopathy (possibly IgA nephropathy) was more likely responsible for his kidney failure and that his death was due to a cardiac arrhythmia or some other complication of uremia.

Their shapes are very different according to the location; neutron energies up to about 200 MeV were recorded. The dosimetry was performed with various active instruments: 2202D, LB 6411, LINUS, nm 500, nm 500X, HANDI, REM 500. The comparison between the H*(10) values determined by different systems is presented and discussed.

Dynamics of charged particles in a Paul radio-frequency quadrupole trap  

NASA Technical Reports Server (NTRS)

A molecular-dynamics simulation of hundreds of ions confined in a Paul trap has been performed. The simulation includes the trapped particles' micromotion and interparticle Coulomb interactions. A random walk in velocity was implemented to bring the secular motion to a given temperature which was numerically measured. When the coupling Gamma is large the ions from concentric shells which undergo a quadrupole oscillation at the RF frequency, while the ions within a shell form a 2D hexagonal lattice. Ion clouds at 5 mK show no RF heating for q(z) less than about 0.6, whereas rapid heating is seen for qz = 0.8.

Our perception of the mast cell from Paul Ehrlich to now  

PubMed Central

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

Transverse Beam Compression by Adiabatic Waveform Changes in the Paul Trap Simulator Experiment (PTSX)  

NASA Astrophysics Data System (ADS)

The Paul Trap Simulator Experiment (PTSX) is a compact laboratory Paul trap that simulates a long, thin charged-particle bunch coasting through a kilometers-long magnetic alternating-gradient transport system by putting the physicist in the frame-of-reference of the beam. The transverse dynamics of particles in both systems are described by the same sets of equations -- including all nonlinear space-charge effects. Results are presented from experiments in which the amplitude and frequency of the applied confining voltage are adiabatically changed over time in order to transversely compress a beam with an initial depressed-tune ?/?0˜0.9. Emphasis is placed on determining the conditions that minimize emittance growth and the number of particles that are found at large radius (so-called halo particles) after the beam compression. It is found that increases of up to a factor of two in the lattice strength can be implemented in only four lattice periods. The results of PIC simulations performed with the WARP code agree well with the experimental data.

Midface osteotomies lines: evolution by Paul Tessier, the second Tessier classification.  

PubMed

The Tessier collection is an inheritance of a whole career of a surgeon and a life dedicated to cranio-facial malformations. It is a good opportunity to analyse some particular points of the surgical work of Paul Tessier, in particular to understand how the midface advancement procedures were made up and thought out. Medical files, pictures, X-rays and drawings help us to describe step by step the different types of midface osteotomies done by Paul Tessier, from TESSIER I to TESSIER VII osteotomies. The author describes the reason for the surgical lines and their modifications justified by all those files and by Tessier's personal annotations. Based on a single clinical case, Tessier experimented with new surgical procedures, firstly on skulls and dissection then the proposed surgery, the experience of the surgery and the post-operative result for each patient made him decide to change lines and procedures. At each step, the modification was done to improve stability, aesthetics, or to do the procedure in an easier way. Difficulties and mistakes were always new lessons for further patients.

Long-term drifts of stray electric fields in a Paul trap  

NASA Astrophysics Data System (ADS)

We investigate the evolution of quasi-static stray electric fields in a linear Paul trap over a period of several months. Depending on how these electric fields are initially induced, we observe very different timescales for the field drifts. Photo-induced electric fields decay on timescales of days. We interpret this as photo-electrically generated charges on insulating materials which decay via discharge currents. In contrast, stray fields due to the exposure of the ion trap to a beam of Ba atoms mainly exhibit slow dynamics on the order of months. We explain this observation as a consequence of a coating of the trap electrodes by the atomic beam. This may lead to contact potentials which can slowly drift over time due to atomic diffusion and chemical processes on the surface. In order not to perturb the field evolutions, we suppress the generation of additional charges and atomic coatings in the Paul trap during the measurements. For this, we shield the ion trap from ambient light and only allow the use of near-infrared lasers. Furthermore, we minimize the flux of atoms into the ion trap chamber. Long-term operation of our shielded trap led us to a regime of very low residual electric field drifts of less than 0.03 V/m per day.

Absence of Pauling's residual entropy in thermally equilibrated Dy2Ti2O7  

NASA Astrophysics Data System (ADS)

The discovery of the spin-ice phase in Dy2Ti2O7 numbers among the most significant findings in magnetic materials in over a decade. Spin ice has since been associated with the manifestation of magnetic monopoles and may even inform our understanding of emergent quantum electrodynamics. The spin-ice model is based on an elegant analogy to Pauling's model of geometrical frustration in water ice, and predicts the same residual entropy, as confirmed by numerous measurements. Here we present results for the specific heat of Dy2Ti2O7, demonstrating why previous measurements were unable to correctly capture its low-temperature behaviour. By carefully tracking the flow of heat into and out of the material, we observe a non-vanishing specific heat that has not previously been detected. This behaviour is confirmed in two samples of Dy2Ti2O7, in which cooling below 0.6K reveals a deviation from Pauling's residual entropy, calling into question the true magnetic ground state of spin ice.

Development of a preprototype Sabatier CO2 reduction subsystem  

NASA Technical Reports Server (NTRS)

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

Aharonov–Bohm effect in the tunnelling of a quantum rotor in a linear Paul trap  

NASA Astrophysics Data System (ADS)

Quantum tunnelling is a common fundamental quantum mechanical phenomenon that originates from the wave-like characteristics of quantum particles. Although the quantum tunnelling effect was first observed 85 years ago, some questions regarding the dynamics of quantum tunnelling remain unresolved. Here we realize a quantum tunnelling system using two-dimensional ionic structures in a linear Paul trap. We demonstrate that the charged particles in this quantum tunnelling system are coupled to the vector potential of a magnetic field throughout the entire process, even during quantum tunnelling, as indicated by the manifestation of the Aharonov–Bohm effect in this system. The tunnelling rate of the structures periodically depends on the strength of the magnetic field, whose period is the same as the magnetic flux quantum ?0 through the rotor [(0.99±0.07) × ?0].

Loading of large ion Coulomb crystals into a linear Paul trap incorporating an optical cavity  

NASA Astrophysics Data System (ADS)

We report on the loading of large ion Coulomb crystals into a linear Paul trap incorporating a high-finesse optical cavity (?˜3000). We show that, even though the 3-mm diameter dielectric cavity mirrors are placed between the trap electrodes and separated by only 12 mm, it is possible to produce in situ ion Coulomb crystals containing more than 105 calcium ions of various isotopes and with lengths of up to several millimeters along the cavity axis. We show that the number of ions inside the cavity mode is, in principle, high enough to achieve strong collective coupling between the ion Coulomb crystal and the cavity field. The results thus represent an important step towards ion trap based Cavity Quantum ElectroDynamics (CQED) experiments using cold ion Coulomb crystals.

Richard Arwed Pfeifer (1877-1957) was one of the initiators and foster fathers of the renowned child-psychiatric and special needs education workgroup at Leipzig University under Paul Schröder (1873-1941) in the 1920s and 1930s. This paper is an account of their dispute concerning the interrelations between child and adolescent psychiatry and special needs education, as well as their disagreement about whether adolescent psychopaths should be admitted to specialized child psychiatric wards or elsewhere. Moreover, Pfeifer questioned the practical relevance of the separation of constitutional and environmentally-based psychopathy and fought eugenic research, which he found incompatible with the ethics of his profession as a remedial teacher and child psychiatrist.

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

USGS Publications Warehouse

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

[Ilya Ilich Metchnikov and Paul Ehrlich: 1908 Nobel Prize winners for their research on immunity].  

PubMed

The Nobel Prize in Physiology or Medicine in 1908 was awarded to Ilya I. Mechnikov and Paul Ehrlich for recognition of their work on immunity. Mechnikov have discovered phagocytes and phagocytosis as the basis of natural cellular immunity. His ,,phagocytic theory" is the principle of immunological concept "self and not self" as the prerequisition of physiological inflammation, and selfmaintaining of organism. Ehrlich developed the methods for standardization of antibody activity in immune sera, described neutralizing and complement-depending effect of antibodies and enunciated the ,"ide-chain" theory of the formation of antibodies. Their concept of the key-stone of immunity was different, but they expressed the basic paradigma of immunology: immunity imply the protection of identity and guarantee the integrity of organism. Both are the founders of immunology as the scientific discipline. Discoveries and conceptions of I. Mechnikov and P. Ehrlich exceedingly influenced development of immunology and are also applicable, instructive and suggestive in contemporary immunology and microbiology. PMID:19069024

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

PubMed Central

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

Critical thinking in clinical nurse education: application of Paul's model of critical thinking.  

PubMed

Nurse educators recognize that many nursing students have difficulty in making decisions in clinical practice. The ability to make effective, informed decisions in clinical practice requires that nursing students know and apply the processes of critical thinking. Critical thinking is a skill that develops over time and requires the conscious application of this process. There are a number of models in the nursing literature to assist students in the critical thinking process; however, these models tend to focus solely on decision making in hospital settings and are often complex to actualize. In this paper, Paul's Model of Critical Thinking is examined for its application to nursing education. I will demonstrate how the model can be used by clinical nurse educators to assist students to develop critical thinking skills in all health care settings in a way that makes critical thinking skills accessible to students.

We demonstrate that abundant quantities of short-lived beta unstable ions can be trapped in a novel transparent Paul trap and that their decay products can directly be detected in coincidence. Low energy 6He+ (807 ms half-life) ions were extracted from the SPIRAL source at GANIL, then decelerated, cooled, and bunched by means of the buffer gas cooling technique. More than 10(8) ions have been stored over a measuring period of six days, and about 10(5) decay coincidences between the beta particles and the 6Li++ recoiling ions have been recorded. The technique can be extended to other short-lived species, opening new possibilities for trap assisted decay experiments. PMID:19113407

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

Off-resonance energy absorption in a linear Paul trap due to mass selective resonant quenching  

NASA Astrophysics Data System (ADS)

Linear Paul traps (LPT) are used in many experimental studies such as mass spectrometry, atom-ion collisions, and ion-molecule reactions. Mass selective resonant quenching (MSRQ) is implemented in LPT either to identify a charged particle's mass or to remove unwanted ions from a controlled experimental environment. In the latter case, MSRQ can introduce undesired heating to co-trapped ions of different mass, whose secular motion is off resonance with the quenching ac field, which we call off-resonance energy absorption (OREA). We present simulations and experimental evidence that show that the OREA increases exponentially with the number of ions loaded into the trap and with the amplitude of the off-resonance external ac field.

Universal heating curve of damped Coulomb plasmas in a Paul trap  

NASA Astrophysics Data System (ADS)

A charged-particle cloud in a Paul trap is a nonlinear system that exhibits deterministic heating, i.e., conversion of energy provided by the radio-frequency (rf) drive of the trap into the disordered, gaslike motions of the trapped particles. In the presence of weak damping clouds reach an equilibrium state in which heating and cooling balance. For large damping, a cloud may collapse into a crystal. While the rf heating power of a given cloud depends sensitively on its particle number, its equilibrium size, the damping, and the control parameters of the trap, we find that scaling the heating power of the cloud with respect to its associated Coulomb-decoupled, non-interacting-gas state, and its equilibrium size with respect to its crystal size, results in a single, universal heating curve, independent of particle number and trap control parameters.

Commissioning of the new high-intensity ultracold neutron source at the Paul Scherrer Institut  

NASA Astrophysics Data System (ADS)

Commissioning of the new high-intensity ultracold neutron (UCN) source at the Paul Scherrer Institut (PSI) has started in 2009. The design goal of this new generation high intensity UCN source is to surpass by a factor of ~100 the current ultracold neutron densities available for fundamental physics research, with the greatest thrust coming from the search for a neutron electric dipole moment. The PSI UCN source is based on neutron production via proton induced lead spallation, followed by neutron thermalization in heavy water and neutron cooling in a solid deuterium crystal to cold and ultracold energies. A successful beam test with up to 2 mA proton beam on the spallation target was conducted recently. Most source components are installed, others being finally mounted. The installation is on the track for the first cool-down and UCN production in 2010.

Basaltic volcanism in the Bering Sea: geochronology and volcanic evolution of St. Paul Island, Pribilof Islands, Alaska  

NASA Astrophysics Data System (ADS)

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

Studies of charged particle beam dynamics on the Paul Trap Simulator Experiment pure ion plasma  

NASA Astrophysics Data System (ADS)

Based on the compelling physics analogy between intense beam propagating through a periodic focusing quadrupole magnetic field and nonneutral pure ion plasma confined in a linear Paul trap configuration, experimental studies of intense beam propagation under the influence of self-field effects have been performed using the Paul Trap Simulator Experiment (PTSX) device. A new charge collector diagnostic has been implemented, which permits detailed measurement of the radial ion density profile that can be compared with theoretical predictions. To further investigate the trapped plasma properties, a laser-induced fluorescence (LIF) diagnostic system with accompanying barium ion source has also been developed and tested. To achieve a well-characterized initial beam state for subsequent beam physics experiments, ion injection into the trap has been carefully optimized by characterizing various beam dynamics issues that may invalidate the physics analogy between intense coasting beam and trapped pure ion plasma in the quadrupole focusing fields. An optimized plasma is held in the quasi-equilibrium state for more than 50 ms, which is equivalent to more than 3000 full alternating-gradient (AG) focusing periods, and has a defocusing space-charge force that is about 10% of the applied transverse focusing force. The PTSX device is used to investigate basic physics of transverse beam compression. From a comparison of the analytical estimates based on a Kapchinskij-Vladimirskij (KV) beam model, experimental results on changes in both the lattice amplitude and frequency, and particle-in-cell (PIC) simulations, it is found that a key physics issue in transverse beam compression is how to suppress the excitation of mismatch oscillations, which is often accompanied by emittance growth and halo formation. When the phase advance is low enough, adiabatic changes in the smooth-focusing frequency turn out to provide an effective control of transverse beam compression. Machine imperfection effects which are unavoidable in the operation of high-intensity accelerators are also investigated. In particular, the effects of faulty magnet sets and random noise in the AG focusing channel are considered. The excitation of mismatch oscillations is observed as a result of focusing field errors, and their characteristics are effectively explained in terms of the KV-equivalent beam model. A continuous increase in emittance that depends on the noise duration and amplitude is observed, together with the synergistic effects between collective modes and colored noise.

NSDL National Science Digital Library

Subject: Paul Zamecnick Paul Zamecnik was born in Cleveland, Ohio. He went to Dartmouth College and graduated from Dartmouth Medical School in 1934. Although he trained to be a medical doctor, Zamecnik was always interested in science. He eventually decided to go into research because there was so much to discover. His interest in protein synthesis started with a question. In 1938, as an intern, Zamecnik was doing an autopsy on an obese woman. He wondered why there was fat when there should have been protein and muscle ? no one knew the answer. In 1939, Zamecnik approached Max Bergmann, a protein chemist at the Rockefeller Institute. He was hoping to get a job in Bergmann's lab so he could work on the problem of protein synthesis. Bergmann turned him down because Zamecnik was an M.D, not a Ph.D. Zamecnik did get a fellowship to work with Kaj Linderstrøm-Lang at the Carlsberg Laboratory in Denmark. Linderstrøm-Lang was a leader in the field of protein chemistry and Zamecnik obtained enough training and experience that Bergmann gave him a job when he came back to the States. Zamecnik didn't stay at the Rockefeller for long. He was offered a job at the Huntington Laboratory at the Massachusetts General Hospital in Boston. Here, he worked with Fritz Lipmann (1953 Nobel laureate) and used radioactive isotopes to prove that proteins were built from amino acids in a process requiring chemical energy ? ATP. Zamecnik then became interested in how protein sequences were specified and to understand that he tried to isolate and identify all the components necessary for protein synthesis. In 1952, Zamecnik was partially successful in that he made a cell-free extract from rat liver with which he was able to synthesize proteins from amino acids. In 1953, using this system, Zamecnik and Mahlon Hoagland showed that amino acids had to be energized, "activated," by ATP before they were incorporated into a peptide chain. Then in 1956, Hoagland followed up on an observation Zamecnik made earlier. Zamecnik noticed that low molecular weight RNA in the cell-free extract could be associated with radiolabeled amino acids. This led to the identification of tRNA ? the adaptors Francis Crick predicted in his Central Dogma.

Multiple strains of Coxiella burnetii are present in the environment of St. Paul Island, Alaska.  

PubMed

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

Proton Irradiation Facility and space radiation monitoring at the Paul Scherrer Institute.  

PubMed

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

Death of John Paul II and the basic human care for the sick and the dying.  

PubMed

The death of Terri Schiavo by starvation and its sanction by some United States Courts indicates the alarming revival of the eugenics and euthanasia movement. From the legal sanction of physician-assisted suicide, the euthanasia movement now tries to advance the legal protection for "mercy killing." Terri was diagnosed with persistent vegetative state, a term that is outdated, vague and imprecise and that likens a human being to a vegetable. Medical literature indicates that patient with so-called "persistent vegetative state" can recover, and that they do experience pain. The euthanasia movement, linked to eugenics in its origin and present day influence in bioethics espouses the Nazi notion of "lives not worth living," unlimited patient autonomy, and philosophical utilitarianism. John Paul II countered the eugenic philosophy with the classical Western concept of man as the image and likeness of God, responsible for the care of himself and society as a whole. He taught in writing and by example that food and water are basic human care that every person should receive. In the last days of his life he showed a judicious use of proportionate or ordinary means to maintain life. He chose to forego disproportionate medical treatment when there was no reasonable hope of recovery. At that point he continued to receive ordinary medical care, together with basic human and spiritual care. PMID:16475275

Miniaturized system of a gas chromatograph coupled with a Paul ion trap mass spectrometer  

NASA Technical Reports Server (NTRS)

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

Quantum control of 88Sr+ in a miniature linear Paul trap  

NASA Astrophysics Data System (ADS)

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

The search for the neutron electric dipole moment at the Paul Scherrer Institute  

NASA Astrophysics Data System (ADS)

The measurement of the neutron electric dipole moment (nEDM) constrains the contribution of CP-violating terms within both the Standard Model and its extensions. The experiment uses ultracold neutrons (UCN) stored in vacuum at room temperature. This technique provided the last (and best) limit by the RAL/Sussex/ILL collaboration in 2006: dn < 2:9 × 10 -26 e cm (90% C.L.). We aim to improve the experimental sensitivity by a factor of 5 within 2-3 years, using an upgrade of the same apparatus. We will take advantage of the increased ultracold neutron density at the Paul Scherrer Institute (PSI) and of a new concept including both, external magnetometers and a cohabiting magnetometer. In parallel, a next generation apparatus with two UCN storage chambers and an elaborate magnetic field control is being designed aiming to achieve another order of magnitude increase in sensitivity, allowing us to put a limit as tight as dn < 5 × 10 -28 e cm (95% C.L.), if not establishing a finite value.

Influence of water on the mineralogy and microstructure of mylonites from St. Paul's Rocks, Equatorial Atlantic  

NASA Astrophysics Data System (ADS)

St. Paul's Rocks (SPR) are a unique set of islets in the Equatorial Atlantic, which represent the only subaerial exposure of an active transform fault along the global ridge system. The islets cap a submarine massif that extends to ~3km below sea level. The massif itself lies within the larger St. Paul's Transform Fault, which is approximately 540km long and composed of four transform fault segments separated by three intra-transform spreading ridges. The SPR islets are also unique as they are almost entirely composed of peridotite mylonites with unusual microstructures and mineralogy. Early studies of SPR noted the presence of minerals uncommon in ultramafic rocks, including scapolite and hydrous minerals such as amphibole (Melson et al., 1967; Roden et al., 1984). Our observations also indicate the presence of a strong lattice preferred orientation (LPO) among both olivine and amphibole. To better understand the microstructural and mineralogical evolution of the SPR peridotite mylonites, we carried out combined EBSD-EDS analysis. Results show a pronounced olivine LPO that corresponds to predominant slip in the [010] direction on both the (100) and (001) planes. This indicates deformation by dislocation creep, whereas olivine flow laws - at least for dry rheology - predict a transition to diffusion creep among the 1-10 micron grain size population of the sample. In addition, our results show the amphibole phase is Ti-rich pargasite, which is unexpectedly ubiquitous, including in a sample previously assumed to contain only olivine. Phlogopite, scapolite and plagioclase were also found to be present. Pargasite and scapolite are high (~750° C) temperature phases that require the presence of water, chlorine, and plagioclase to form. In order to explain the unique mineralogy and microstructures found in SPR mylonites, we propose a two-stage model for their evolution. In the first stage, trapped melt leads to the formation of gabbro veins and plagioclase crystallization, which may have coincided with initial strain localization. In the second stage, seawater infiltrated into the brittle-ductile transition zone (BDTZ), due to episodic propagation of fractures below the zone of brittle faulting. This results in the reaction of seawater with pyroxene, forsterite and plagioclase to form pargasite and scapolite. The second stage was coincident with strain localization and mylonitization, as indicated by olivine recrystallization and the presence of olivine and pargasite LPOs. Deep circulation of seawater is consistent with numerical models of oceanic transform faults proposed by Roland et al., (2010), which show that hydrothermal alteration can extend into the upper mantle. In addition, McGuire et al. (2012) recorded foreshocks beneath the Gofar transform fault at depth corresponding to the mantle BDTZ. Our petrographic and microstructural observations demonstrate that seawater can penetrate the upper mantle beneath oceanic transform faults to greater depths than previously thought. This results in high temperature alteration of mantle peridotites in the BDTZ, followed by ductile deformation that gives rise to the strong LPOs observed in forsterite and pargasite.

Historical ecology in Beringia: The south land bridge coast at St. Paul Island  

NASA Astrophysics Data System (ADS)

A 14-m core of lake sediments from St. Paul Island yields a long environmental history of the south coast of the Bering land bridge. Tritium assay demonstrates that sands in the bottom 8 m of deposit are injected with modern water, suggesting that a radiocarbon anomaly is the result of modern carbon introduced in groundwater. The remaining radiocarbon chronology, coupled with a time-stratigraphic pollen-zone boundary suggests that the record penetrates to the mid-Wisconsin interstadial. Pollen percentage data, Picea pollen influx, and pollen species lists allow reconstruction of the land bridge vegetation, which was tundra, without shrubs or trees, with bare ground, and comparable to Bering land bridge tundras found further north. There was no coastal mild or wet strip. Plant associations comparable to those of the modern Aleutians or Pribilofs probably did not exist along the land bridge coast and the region was probably not suitable for breeding by fur seals and other marine mammals. A cold, dry, continental air-mass system reached to the coast itself. The south land bridge coast did not offer an environment to aboriginal human populations that was significantly milder than that of the land bridge plains to the north. At about 11,000 yr B.P. the Wisconsin dry climate was replaced by a regimen comparable to that at the modern tree line of the interior, and this climate in turn was replaced with the modern system at about 9500 yr B.P. Climatic change was independent of fluctuating sea level.

Geochemical and Hf-Pb-Sr-Nd isotopic constraints on the origin of the Amsterdam-St. Paul (Indian Ocean) hotspot basalts  

NASA Astrophysics Data System (ADS)

The Amsterdam-St. Paul (ASP) Plateau is a recent (?5 Ma) volcanic rise constructed along the Southeast Indian Ridge (SEIR) by the combined effects of a relatively small mantle plume and a mid-oceanic ridge. The Amsterdam and St. Paul islands are located 100 km away from each other and formed during the last 0.4 Myr; they are the only subaerial features of the ASP Plateau and the two islands are structurally separated by the presence of a SW-NE transform fault. New geochemical analyses and Hf-Pb-Sr-Nd isotopic compositions of 20 basaltic rocks from Amsterdam and St. Paul Islands constrain the nature and origin of the sources involved in the genesis of the ASP hotspot basalts. Aphyric basalts from St. Paul are mildly alkalic, incompatible element-enriched and highly fractionated; they are distinct from the tholeiitic basalts from Amsterdam, from the recently discovered Boomerang active seamount on the ASP Plateau, and from the Kerguelen Archipelago basalts on the Antarctic Plate. The St. Paul and Amsterdam basalts have very limited isotopic variations with distinct 206Pb/ 204Pb, 207Pb/ 204Pb, 208Pb/ 204Pb, and 176Hf/ 177Hf isotopic compositions (19.08±0.07, 15.61±0.02, 39.45±0.12, 0.28313±0.00003 for Amsterdam, and 18.70±0.08, 15.56±0.01, 38.87±0.05, 0.28306±0.00002 for St. Paul, respectively) that are not compatible with any direct contribution of the enriched Kerguelen plume end-member. Pb-Nd-Sr isotopic compositions of the St. Paul basalts appear consistent with simple binary mixtures between heterogeneous ambient upper mantle and a highly radiogenic Pb plume component (the ASP plume end-member), particularly expressed in the isotopic compositions of the Amsterdam basalts. However, the Amsterdam basalts have distinctly higher ?Hf than the St. Paul basalts (+13 and +10, respectively) for a given ?Nd (+4) and are inconsistent with such a simple binary mixing scenario. Isotopic systematics in the Amsterdam and St. Paul basalts indicate that the Amsterdam and St. Paul volcanoes were formed by sampling isotopically distinct zones of the ASP plume at a lateral distance of 100 km. Less than 1% variation in the proportion of recycled altered oceanic crust relative to pelagic sediment, combined with minor variations in the proportion of recycled material within the Amsterdam and St. Paul plume sources themselves relative to a peridotitic mantle source, could account for the isotopic differences between the compositions of basalts from these two islands. The particularly high 206Pb/ 204Pb component recorded in the Amsterdam and St. Paul basalts is also locally recorded at different times and locations within other Indian Ocean basalts (e.g. Ninetyeast Ridge basalts, 38 Ma) and such a component has also contaminated the source of SEIR basalts to varying degrees. The particularly high 206Pb/ 204Pb component is therefore not exclusive to the Amsterdam-St. Paul plume but is heterogeneously distributed within the Indian Ocean upper mantle. This may reflect the role of the Indian mantle plumes in dispersing recycled material within the Indian upper mantle.

Simulations of the dynamics of ions trapped in a Paul trap with terms in the potential up to the order 10 have been carried out. The power series method is used to solve numerically the equations of motion of the ions. The stability diagram has been studied and the buffer gas cooling has been implemented by a Monte Carlo method. The dipole excitation was also included. The method has been applied to an existing trap and it has shown good agreement with the experimental results and previous simulations using other methods.

Detection of linkage to affective disorders in the catalogued Amish pedigrees: A reply to Pauls et al.  

SciTech Connect

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

Time-dependent perturbation theory approach to the quantum motion of a particle in a Paul trap  

NASA Astrophysics Data System (ADS)

The main objective of this study is to investigate the quantum mechanical lifetime of a trapped ion in a Paul trap. The motivation for this research is that there are several applications of trapped ion devices such as mass spectrometers, atomic clocks, and quantum computers. Active research is presently ongoing in the subject of an ion trapping by electric and magnetic fields. There are many classical studies of the characteristics of trapped ions, however there have been relatively few done quantum mechanically. It might be expected that purely quantum effects could play an important role in describing the trapped ions. So, those are the main factors behind the research on this topic. Time-dependent perturbation theory was used in this study which is to find the quantum mechanical lifetime of trapped ion in a Paul trap because time-dependent perturbation theory allows describing the complex system with the help of a simple system that can be calculated easily. It is shown that the lifetime of a trapped ion depends on its transition frequency and the transition between two allowed quantum states of the ion. The transition frequency of an ion has to be very close to the applied frequency of alternating current (AC). The results show that the lifetime of a trapped ion can be adjusted as desired for experimentation.

Noble gas behavior during deformation and serpentinization of abyssal peridotites: St. Peter-St. Paul massif  

NASA Astrophysics Data System (ADS)

We present new noble gas (He, Ne, Ar), Sr and Pb isotopic analyses of St. Peter-St. Paul (SPSP) abyssal peridotites sampled in 1998-1999 using the Nautile submersible (IFREMER). The goals of the study were to geochemically characterize both granular and mylonitized peridotites, and to evaluate the effects of mylonitization and serpentinization on rare gas concentrations and isotopic compositions. Samples included whole rocks for mylonitic peridotites, and mineral separates (serpentine and olivine+pyroxene) from massive peridotites. The abyssal peridotites exhibit strong enrichment in light rare earths and other incompatible elements, and positive Ce anomalies are found in several non-mylonitic samples. Mylonitic samples are characterized by lower loss on ignition, and higher SiO2 and MgO, and unradiogenic 87Sr/86Sr isotopic composition (~0.7034) and extremely radiogenic 206Pb/204Pb (up to 20), which is more radiogenic than previous measurements from SPSP. Rare gas analyses were made by paired in vacuo crushing and melting of whole rocks and mineral separates. Most SPSP peridotites contain high concentrations of He, Ne, and Ar that are air-like demonstrating atmospheric contamination. The group of samples plots along a He-Ne mixing line between air and typical mantle values, where the mylonitic samples are characterized by higher fractions of mantle Ne (20Ne/22Ne>10) and 3He/4He (R/Ra~7). The binary mixing behavior is also supported by Ar-Ne isotopes. For the mylonites, melting released high concentrations of He (1.4x10-5ccSTP/g) and the most radiogenic argon (40Ar/36Ar = 2810), demonstrating that noble gases are stored in the crystal structure of the minerals. In contrast, the undeformed peridotites had much lower total helium concentrations for both serpentine (2x10-8ccSTP/g) and olivine+pyroxene (6.9x10-8ccSTP/g) separates. The serpentine mineral separate showed low 3He/4He (R/Ra~1) that was similar in both crushed and melting methods and low air-like 40Ar/36Ar (~355), although they released the highest argon concentration (3.2x10-5cc/g). The low He concentrations suggest that serpentine is not a determining mineral phase in He fractionation. The olivine+pyroxene mineral separates yield lower 3He/4He through the melting method and similar to whole rock values and lower 40Ar/36Ar (~383). Because melt inclusions are not found in the mylonites, the large fraction of 4He released during melting suggests that a significant mantle component may be retained in the recrystallized neoblasts during the deformation processes. It is hypothesized that recrystallization and grain growth in the mylonitization process may have favored gas retention (i.e. supporting a relationship between deformation and gas contents), or is related to metasomatism in a gas-rich (CO2 and rare gas) environment.

"Paul Klee and the hypothesis of morphic resonance". Adjustment to illness and life history of patients with progressive systemic scleroderma.  

PubMed

Within the context of a Psychoanalytic Psychosomatic Medicine the biography of Paul Klee is analysed, who suffered during his last years from progressive systemic scleroderma. Amongst the pervading and characteristic motives of his life and his work, the motives of the dragon-like demon and that of the Dead are introduced. Both are shown to relate to his illness as well as to a highly significant narcissistic idealized picture of his grandmother on the mother's side. Finally, a general biological hypothesis--Sheldrake's hypothesis of morphogenetic fields and morphic resonance--is laid out for the domain of Psychosomatic Medicine. According to this hypothesis, primary process characteristics such as condensation and displacement are also seen to be valid in the somatic domain without being restricted only to conversion events.

ON THE MAKING OF A SYSTEM THEORY OF LIFE: PAUL A WEISS AND LUDWIG VON BERTALANFFY'S CONCEPTUAL CONNECTION  

PubMed Central

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

A drift experiment to assess the influence of wind on recovery of oiled seabirds on St Paul Island, Alaska  

USGS Publications Warehouse

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

Structural variants and the modified Slater-Pauling curve for transition-metal-based half-Heusler alloys  

NASA Astrophysics Data System (ADS)

We compare the physical differences between two atomic configurations, found in the literature, of the half-Heusler alloys--XMnY, where X is a transition-metal element and Y is a nonmetallic element. The structural differences arise from the placement of the X and Y atoms and the vacancy within the full-Heusler (L21) structure. In one configuration, Y and Mn are nearest neighbors and the vacancy is at (1/4,3/4,1/4)a (4d) while in the other configuration, X and Mn are nearest neighbors and the vacancy is located at (0,0,1/2)a (4b), where a is the lattice constant of face-centered cube. We suggest that the important difference between the two configurations is the identity of the transition-metal element nearest to the non-metal element. Physical properties, in particular the bonding features, reflect this difference. The general validity of the modified Slater-Pauling curve, which gives successful zeroth-order prediction of the magnetic moments of many half-Heusler alloys including CrMnSb in the second configuration, is tested in the six XMnY alloys studied here. Their calculated moments obey the predictions by the modified Slater-Pauling curve for positive moments only. Exceptions appear for predictions with negative moments. A simple and plausible physical reason is provided. Furthermore, the possibility of a non-ferromagnetic phase is examined and the energetics between the ferromagnetic and non-ferromagnetic phases are compared.

Parametric Investigations of an Atmospheric pressure Uniform Glow Discharge in helium  

NASA Astrophysics Data System (ADS)

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

Morphological and karyotypic differentiation in Caranx lugubris (Perciformes: Carangidae) in the St. Peter and St. Paul Archipelago, mid-Atlantic Ridge  

NASA Astrophysics Data System (ADS)

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

North-south compression, active uplift, and abyssal mantle exhumation of the Saint Peter and Saint Paul Rock, Equatorial Atlantic Ocean  

NASA Astrophysics Data System (ADS)

This article presents near N-S compression, active uplift tectonism, and the consequent abyssal mantle exhumation of the Saint Peter and Saint Paul Rock, Equatorial Atlantic Ocean. The mantle peridotite ridge is about 80 km long, 25 km wide, 3800 m high, and of near E-W direction. The ridge flanks are extremely steep with sub-vertical scarps of about 2000 m of relative height. The Flandrian wave-cut and the 14C datings for the carbonaceous algae of the Saint Peter and Saint Paul Rock indicate active uplift of 1.5 mm/year. The tectonic factures shows conjugated system of N-S compression tending slightly to NW-ES. Close to the peridotite ridge, the earthquakes with near N-S compression focal mechanism take place. The southern half of the peridotite ridge is constituted by undeformed peridotite. The existence of corrugation morphology indicates that the mantle rocks are originated from old megamullion. On the other hand, the northern half is composed of strongly deformed mylonitic peridotite suggesting that the ultramafic rocks are possibly originated from sub-crustal abyssal mantle of old transform fault. The mylonite structure is intensely perturbed indicating the tectonic events which disturbed the original parallel structure. The Saint Paul transform fault zone is characterized by E-W trend right lateral movement and the near N-S compression is unlikely. Therefore, an unusual local geotectonic process is expected. This tectonism was originated from the plate boundary jump at about 8 Ma, caused by the emergence of a new ridge segment, and the new transform fault is oblique to the relative plate movement. This angular discrepancy causes the compression perpendicular to the oblique transform fault, of near N-S direction, which squeeze out the sub-crustal abyssal mantle up to sea level. Therefore, the peridotite Ridge is considered to be a pressure ridge of the strike-slip movement of the Saint Paul transform fault.

Coulomb crystals in a cryogenic Paul trap for sympathetic cooling of molecular ions and highly charged ions  

NASA Astrophysics Data System (ADS)

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

Perfluorinated compound concentrations in great blue heron eggs near St. Paul, Minnesota, USA, in 1993 and 2010-2011.  

PubMed

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

[Knowledge of German neurologists on migraine around 1890. Paul Julius Möbius and his 1894 monograph Die Migräne].  

PubMed

Paul Julius Möbius (1853-1907), a Leipzig-based author and editor on a vast majority of subjects, has often been acknowledged as a leading 19th-century German neurologist. His impact on the development of knowledge on migraine has likewise been pointed to. This study compares the monograph published by Möbius on the illness in 1894 with contemporary publications and with present day best practice to establish if the author really made an essential contribution to the problem of migraine. As a representative of the central theory Möbius assumed that migraine was caused by aberrations in the brain. At the same time he made it clear that due to very limited diagnostic options this was only a hypothesis. Apart from a genetic factor and these cerebral changes, for Möbius the general state of health was a decisive factor and prevention and change in lifestyle therefore played a crucial role in his therapeutic recommendations. Basically there were only few differences between the views of Möbius and his colleagues, the major dissimilarity being that Möbius postulated a merely suggestive impact but no physical effect of electrotherapy. Although Möbius's monograph on migraine lacks originality, it provides a concise, easy to understand and stylistically impressive overview on the state of knowledge at that time. Therefore, the book can be considered as a benchmark publication of German speaking neurology around 1890 on migraine and it is highly recommended to present day headache and migraine researchers as well as historians of psychiatry and neurology.

Slater-Pauling behavior within quaternary intermetallic borides of the Ti 3Co 5B 2 structure-type  

NASA Astrophysics Data System (ADS)

First-principles, density-functional studies of several intermetallic borides of the general type M2M'Ru 5-nRh nB 2 ( n=0-5; M=Sc, Ti, Nb; M'=Fe, Co) show that the variation in saturation magnetic moment with valence-electron count follows a Slater-Pauling curve, with a maximum moment occurring typically at 66 valence electrons. The magnetic moments in these compounds occur primarily from the 3 d electrons of the magnetically active M' sites, with some contribution from the Ru/Rh sites via magnetic polarization. Electronic DOS curves reveal that a rigid-band approach is a reasonable approximation for the estimation of saturation moments and the analysis of orbital interactions in this family of complex borides. COHP analyses of the M'- M' orbital interactions indicate optimized interactions in the minority spin states for Co-containing phases, but strong bonding interactions remaining in Fe-containing phases.

The Contributions of Paul Ehrlich to Pharmacology: A Tribute on the Occasion of the Centenary of His Nobel Prize  

PubMed Central

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

pAUL: A Gateway-Based Vector System for Adaptive Expression and Flexible Tagging of Proteins in Arabidopsis  

PubMed Central

Determination of protein function requires tools that allow its detection and/or purification. As generation of specific antibodies often is laborious and insufficient, protein tagging using epitopes that are recognized by commercially available antibodies and matrices appears more promising. Also, proper spatial and temporal expression of tagged proteins is required to prevent falsification of results. We developed a new series of binary Gateway cloning vectors named pAUL1-20 for C- and N-terminal in-frame fusion of proteins to four different tags: a single (i) HA epitope and (ii) Strep-tagIII, (iii) both epitopes combined to a double tag, and (iv) a triple tag consisting of the double tag extended by a Protein A tag possessing a 3C protease cleavage site. Expression can be driven by either the 35 S CaMV promoter or, for C-terminal fusions, promoters from genes encoding the chloroplast biogenesis factors HCF107, HCF136, or HCF173. Fusions of the four promoters to the GUS gene showed that endogenous promoter sequences are functional and drive expression more moderately and consistently throughout different transgenic lines when compared to the 35 S CaMV promoter. By testing complementation of mutations affected in chloroplast biogenesis factors HCF107 and HCF208, we found that the effect of different promoters and tags on protein function strongly depends on the protein itself. Single-step and tandem affinity purification of HCF208 via different tags confirmed the integrity of the cloned tags.

Response of sedimentary microbial communities to sedimentation events and environmental change in urban lakes - Minneapolis-St. Paul, MN  

NASA Astrophysics Data System (ADS)

Microorganisms must migrate in order to maintain position with respect to geochemical gradients, and many exhibit tactic behavior to optimize their position. However, certain microorganisms in subsurface environments form persistent attachments to solid particles or are non-motile, leading to the differential burial of a subset of active cells (i.e. what is preserved may differ from what is—or was—active at a given horizon). Deep sedimentary horizons may inherit a microbial community that fails to maintain its optimum position with respect to geochemical profiles. Few studies have attempted to constrain how changes in sediment accumulation or lithology impact microbial diversity and abundance. Oligomictic Lake McCarrons and meromictic Brownie Lake, both located within the Minneapolis-St. Paul, MN metropolitan area, represent the impact of urban runoff and land use changes leading to eutrophication and bottom water anoxia over the past century. Previous studies have exhibited a rich historical record in the lake sediments, with significant lithological transitions linked to human activity and efforts to mitigate long-term internal phosphorus loading. In July, 2012, freeze cores were collected from the top ~1m of sediment beneath the deepest, oxygen-depleted waters of each lake in order to characterize the 16S rRNA gene diversity of microbial communities present in distinct lithological horizons as well as the extent of community signature transgression across sedimentary boundary layers. A ~5cm horizon of amorphous aluminum hydroxide resulting from a 2004 Lake McCarrons alum (aluminum sulfate) treatment was selected for high-resolution study as well as the layers corresponding to the ~1925 Brownie Lake transition to bottom water anoxia. Terminal Restriction Fragment Length Polymorphism (T-RFLP) profiles referencing amplicon sequence libraries generated from select horizons provide constraints on vertical migration of microbial communities in response to sedimentation.

Studies of emittance growth and halo particle production in intense charged particle beams using the Paul Trap Simulator Experiment  

NASA Astrophysics Data System (ADS)

The Paul Trap Simulator Experiment (PTSX) is a compact laboratory experiment that places the physicist in the frame-of-reference of a long, charged-particle bunch coasting through a kilometers-long magnetic alternating-gradient (AG) transport system. The transverse dynamics of particles in both systems are described by the same set of equations, including nonlinear space-charge effects. The time-dependent voltages applied to the PTSX quadrupole electrodes in the laboratory frame are equivalent to the spatially periodic magnetic fields applied in the AG system. The transverse emittance of the charge bunch, which is a measure of the area in the transverse phase space that the beam distribution occupies, is an important metric of beam quality. Maintaining low emittance is an important goal when defining AG system tolerances and when designing AG systems to perform beam manipulations such as transverse beam compression. Results are reviewed from experiments in which white noise and colored noise of various amplitudes and durations have been applied to the PTSX electrodes. This noise is observed to drive continuous emittance growth and increase in root-mean-square beam radius over hundreds of lattice periods. Additional results are reviewed from experiments that determine the conditions necessary to adiabatically reduce the charge bunch's transverse size and simultaneously maintain high beam quality. During adiabatic transitions, there is no change in the transverse emittance. The transverse compression can be achieved either by a gradual change in the PTSX voltage waveform amplitude or frequency. Results are presented from experiments in which low emittance is achieved by using focusing-off-defocusing-off waveforms.

The 200-MeV proton therapy project at the Paul Scherrer Institute: conceptual design and practical realization.  

PubMed

The new proton therapy facility is being assembled at the Paul Scherrer Institute (PSI). The beam delivered by the PSI sector cyclotron can be split and brought into a new hall where it is degraded from 590 MeV down to an energy in the range of 85-270 MeV. A new beam line following the degrader is used to clean the low-energetic beam in phase space and momentum band. The analyzed beam is then injected into a compact isocentric gantry, where it is applied to the patient using a new dynamic treatment modality, the so-called spot-scanning technique. This technique will permit full three-dimensional conformation of the dose to the target volume to be realized in a routine way without the need for individualized patient hardware like collimators and compensators. By combining the scanning of the focused pencil beam within the beam optics of the gantry and by mounting the patient table eccentrically on the gantry, the diameter of the rotating structure has been reduced to only 4 m. In the article the degrees of freedom available on the gantry to apply the beam to the patient (with two rotations for head treatments) are also discussed. The devices for the positioning of the patient on the gantry (x rays and proton radiography) and outside the treatment room (the patient transporter system and the modified mechanics of the computer tomograph unit) are briefly presented. The status of the facility and first experimental results are introduced for later reference. PMID:7715569

Spot-scanning proton therapy for malignant soft tissue tumors in childhood: First experiences at the Paul Scherrer Institute  

SciTech Connect

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

Carbon, nitrogen, and phosphorus fluxes in household ecosystems in the Minneapolis-Saint Paul, Minnesota, urban region.  

PubMed

Rapid worldwide urbanization calls for a better understanding of the biogeochemical cycling of those macroelements that have large environmental impacts in cities. This study, part of the Twin Cities Household Ecosystem Project, quantified fluxes of carbon (C), nitrogen (N), and phosphorus (P) at the scale of individual households in the Minneapolis-Saint Paul metropolitan area in Minnesota, USA. We estimated input and output fluxes associated with several components of household activities including air and motor vehicle travel, food consumption, home energy use, landscape, pets, and paper and plastic use for 360 owner-occupied, stand-alone households. A few component fluxes dominated total input fluxes of elements. For instance, air and motor vehicle transportation, together with home energy use, accounted for 85% of total C consumption and emissions. All total and component fluxes were skewed to varying degrees, suggesting that policies targeting disproportionately high fluxes could be an effective and efficient way to reduce pollution. For example, 20% of households contributed 75% of air travel emissions and 40% of motor vehicle emissions. Home energy use was more nearly normally distributed. Nitrogen fluxes were dominated by human diet and lawn fertilizer applications, which together accounted for 65% of total household N inputs. The majority of P inputs were associated with human diet, use of detergents, and pet food. A large portion of the variation among household fluxes of C, N, and P was related to a few biophysical variables. A better understanding of the biophysical, demographic, and behavioral drivers of household activities that contribute to C, N, and P fluxes is pivotal for developing accurate urban biogeochemical models and for informing policies aimed at reducing sources of pollution in urban ecosystems.

Availability, brands, labelling and Salmonella contamination of raw pet food in the Minneapolis/St. Paul area.  

PubMed

The purpose of the study was to characterize the commercially available raw meat pet food diets in the Minneapolis/St. Paul area by (i) determining the number and types of available diets; (ii) assessing pet food stores and brand labels for the provision of precautionary statements regarding the risk of foodborne illness from raw meat; (ii) assessing the labels for Food and Drug Administration (FDA)/American Association of Feed Control Officials (AAFCO) required content and nutrient-related information; and (iv) culturing purchased diets for the presence of Salmonella. Sixty raw meat diets were purchased, representing 11 different brands from eight different stores. Diets were readily available in the form of raw-frozen, dehydrated or freeze-dried varieties from different protein sources, such as lamb, beef, chicken or duck. All stores promoted raw meat diets; however, none provided foodborne illness warnings. Brands varied greatly in their precautionary statements; none of the diets underwent feeding trials; and nutritional adequacy substantiation was through formulation only. The first five ingredients tended to consist of meat, organ meat (by-products), vegetables, grains and ground bones. Currently, it is required that pet foods have an AAFCO nutritional adequacy statement and provide a guaranteed analysis table. Three brands did not meet these FDA requirements. Thirty-one (51.7%) of the 60 raw meat diets underwent some degree of processing including dehydration, freeze-drying or high-pressure pasteurization. Four of the 60 raw diets (7%) tested positive for Salmonella. Analysis of raw meat pet food labels indicated a lack of foodborne illness warnings. Based on these findings, we recommend that warning statements similar to those required by the United States Department of Agriculture and placed on labels of raw meat intended for human consumption be provided on the labels of raw meat pet food diets.

Complex ridge-transform evolution and mantle exhumation at the St. Paul fracture zone system, Equatorial Alantic. Preliminary results from the COLMEIA cruise  

NASA Astrophysics Data System (ADS)

The COLMEIA cruise, held in the Equatorial Atlantic, in the area of the St. Paul transform system, is part of a joint effort between France and Brazil for the study of the Mid-Atlantic ridge near the St. Peter & St. Paul's Rocks. The scientific objective of the cruise was to study in detail the temporal evolution of the complex transform plate boundary, and the origin of the St. Peter-St. Paul mylonitic massif. This area of the Mid-Atlantic ridge was considered to be a mantle 'cold spot', thus a magma-starved region with large occurrences of mantle-derived units outcropping at the seafloor. During the cruise we acquired multibeam echosounder bathymetry, backscattering, water column acoustic data, gravity, magnetics and seismics. 31 dredges successfully returned a wide variety of rocks, including basalts, gabbros and peridotites. The 15 CTD stations with nephelometric profiles casted in the transform region returned a single hydrothermal plume signal, probably sourced in the MAR segment south of the St. Paul system, while no hydrothermal activity was directly detected inside the transform system. 5 autonomous hydrophones were moored in the SOFAR channel around the study area in order to monitor the seismic activity and whale presence; they will be recovered mid-2014. Both bathymetry data and recovered rocks show that the image of a regional amagmatic MAR cannot be applied to the whole of the St. Paul system. The ridge segments are short and narrow, with deep axial valleys. Axial depths are below 4000 m on average, and reach 5400 m in some nodal basins. There is no evidence for a clearly defined neo-volcanic ridge on the axial valley floors, but a few volcanoes were observed in the axial valley of the central segment. The pattern of off-axis abyssal hills is highly variable from one segment to another. The northern segment displays a long sequence of magmatic abyssal hills. The central segment shows both hummocky ridges probably of magmatic origin, alternated to peridotitic ridges as attested by sampling. The southern segment shows few short, symmetric ridges made of peridotite and gabbros. Both the central and the southern segments display asymmetric core complexes nucleating at segments ends. This variety of off-axis morphologies suggest that accretionary processes along the intra-transform segments are unstable and highly variable in space and time. Thus, significant variations in the spreading style were recognized, with a more magmatic northern segment and comparatively less magmatic central and southern segments. However, the existence of long-lived, gabbro cored, core complexes at the western flanks of these later segments suggests that lacking of magma extrusion and presence of mantle-derived rocks at ridge axis, is possibly generated by a reduced efficiency of melt extraction, instead of a reduced magma primary production. We postulate this regime to be controlled by a cold, thick lithosphere where magma is preferentially retained in the crust to create large gabbro bodies. Another striking result is the evidence for compressive stresses across the area, which can be linked to the uplift of the Saint Paul massif. An intense tectonic deformation is attested by the large presence of ultramafic and mafic-derived mylonites associated to km-large shear and thrust zones.

Miniaturized GC/MS instrumentation for in situ measurements: micro gas chromatography coupled with miniature quadrupole array and paul ion trap mass spectrometers  

NASA Technical Reports Server (NTRS)

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

Inter-rater reliability of data elements from a prototype of the Paul Coverdell National Acute Stroke Registry  

PubMed Central

Background The Paul Coverdell National Acute Stroke Registry (PCNASR) is a U.S. based national registry designed to monitor and improve the quality of acute stroke care delivered by hospitals. The registry monitors care through specific performance measures, the accuracy of which depends in part on the reliability of the individual data elements used to construct them. This study describes the inter-rater reliability of data elements collected in Michigan's state-based prototype of the PCNASR. Methods Over a 6-month period, 15 hospitals participating in the Michigan PCNASR prototype submitted data on 2566 acute stroke admissions. Trained hospital staff prospectively identified acute stroke admissions, abstracted chart information, and submitted data to the registry. At each hospital 8 randomly selected cases were re-abstracted by an experienced research nurse. Inter-rater reliability was estimated by the kappa statistic for nominal variables, and intraclass correlation coefficient (ICC) for ordinal and continuous variables. Factors that can negatively impact the kappa statistic (i.e., trait prevalence and rater bias) were also evaluated. Results A total of 104 charts were available for re-abstraction. Excellent reliability (kappa or ICC > 0.75) was observed for many registry variables including age, gender, black race, hemorrhagic stroke, discharge medications, and modified Rankin Score. Agreement was at least moderate (i.e., 0.75 > kappa ?; 0.40) for ischemic stroke, TIA, white race, non-ambulance arrival, hospital transfer and direct admit. However, several variables had poor reliability (kappa < 0.40) including stroke onset time, stroke team consultation, time of initial brain imaging, and discharge destination. There were marked systematic differences between hospital abstractors and the audit abstractor (i.e., rater bias) for many of the data elements recorded in the emergency department. Conclusion The excellent reliability of many of the data elements supports the use of the PCNASR to monitor and improve care. However, the poor reliability for several variables, particularly time-related events in the emergency department, indicates the need for concerted efforts to improve the quality of data collection. Specific recommendations include improvements to data definitions, abstractor training, and the development of ED-based real-time data collection systems.

Relative biologic effectiveness determination in mouse intestine for scanning proton beam at Paul Scherrer Institute, Switzerland. Influence of motion  

SciTech Connect

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

Conditions for minimization of halo particle production during transverse compression of intense ion charge bunches in the Paul Trap Simulator Experiment (PTSX)  

NASA Astrophysics Data System (ADS)

The Paul Trap Simulator Experiment (PTSX) is a compact laboratory Paul trap that simulates propagation of a long, thin charged-particle bunch coasting through a multi-kilometer-long magnetic alternating-gradient (AG) transport system by putting the physicist in the frame-of-reference of the beam. The transverse dynamics of particles in both systems are described by the same sets of equations—including all nonlinear space-charge effects. The time-dependent quadrupolar voltages applied to the PTSX confinement electrodes correspond to the axially dependent magnetic fields applied in the AG system. This paper presents the results of experiments in which the amplitude of the applied confining voltage is changed over the course of the experiment in order to transversely compress a beam with an initial depressed tune ?/ ?0˜0.9. Both instantaneous and smooth changes are considered. Particular emphasis is placed on determining the conditions that minimize the emittance growth and, generally, the number of particles that are found at large radius (so-called halo particles) after the beam compression. The experimental data are also compared with the results of particle-in-cell (PIC) simulations performed with the WARP code.

Evidence for Recycled Crustal Material Within the Upper Mantle Beneath the St Paul Fracture Zone, Equatorial Atlantic  

NASA Astrophysics Data System (ADS)

Several samples of basalts collected along intratransform ridges (ITR) within the St Paul Fracture Zone in the Equatorial Atlantic, have been studied. They were carefully collected using the submersible Nautile and the R/V Nadir. They come from two well identified intratransform ridge segments A and C at 25°27W and 27°42W respectively. All samples are tholeiitic basalts in terms of major element composition although samples from segment C (K20 about 0.4%) are more alkalic than those from segment A (K20 < 0.2%). The same contrast is observed for the REE patterns: Segment C samples exhibit mildly enriched patterns (La/SmN of 1.6) whereas segment A samples are mostly depleted (0.4 < La/SmN <1.0) Ce/Pb ratio is elevated in segment C (35) and "normal" in segment A (20-25). Isotopically, Segment A samples fall within the general North Atlantic trend in a plot of 87Sr/86Sr vs 143Nd/144Nd whereas segment C samples fall below it towards the "1°7N anomaly" identified by Schilling et al. (1994). A comparable distribution is observed for Pb isotopes when 206Pb/204Pb is ploted versus 207Pb/204Pb. Combining Pb and Sr isotopes shows that segment C and 1°7N anomaly samples plot toward an HIMU component. This is supported by the elevated Ce/Pb ratios which are typical of true HIMU basalts (Devey and Hémond, unpublished data on St Helena seamount glasses). These data are in agreement with the presence of an HIMU component within the mantle beneath the Equatorial Atlantic. This component is classically thought to reflect the presence of recycled oceanic crust within the mantle for a long time. This supports the model proposed by Maia et al. (2001) of the existence of recycled lithosphere within the upper mantle based on chemical evidence described by Esperan‡a et al. (1999) using Os isotopes. Studying abyssal peridotites from this area, Esperan‡a et al. have calculated isochron ages of 0.6-1.1 Ga for the recycled component. This relatively young age would explain why this potential HIMU component has not developed yet the characteristic Pb isotopic composition whereas its elevated Ce/Pb ratios agree with such origin. This model is also supported by seismic tomography (Maia et al.2001) which shows the existence of a cold mantle beneath this area within the upper mantle. This thermal anomaly may be also due to the presence of a recycled lithosphere in this region of the mantle. References: Schilling J.G., Hanan B.B., McCully B., Kingsley R.H. (1994) J; Geophys.

Handling Radioactive Waste from the Proton Accelerator Facility at the Paul Scherrer Institut (PSI) - Always Surprising? - 13320  

SciTech Connect

The Paul Scherrer Institut (PSI) is the largest national research centre in Switzerland. Its multidisciplinary research is dedicated to a wide field in natural science and technology as well as particle physics. In this context, PSI is operating, amongst others, a large proton accelerator facility since more than 30 years. In two cyclotrons, protons are accelerated to high speeds and then guided along roughly 100 m of beam line to three different target stations to produce secondary particles like mesons and neutrons for experiments and a separately beam line for UCN. The protons induce spallation processes in the target materials, and also at other beam loss points along the way, with emission of protons, neutrons, hydrogen, tritium, helium, heavier fragments and fission processes. In particular the produced neutrons, due to their large penetration depth, will then interact also with the surrounding materials. These interactions of radiation with matter lead to activation and partly to contamination of machine components and the surrounding infrastructures. Maintenance, operation and decommissioning of installations generate inevitably substantial amounts of radioactive operational and dismantling waste like targets, magnets, collimators, shielding (concrete, steel) and of course secondary waste. To achieve an optimal waste management strategy for interim storage or final disposal, radioactive waste has to be characterized, sorted and treated. This strategy is based on radiation protection demands, raw waste properties (size, material, etc.), and requirements to reduce the volume of waste, mainly for legal and economical reasons. In addition, the radiological limitations for transportation of the waste packages to a future disposal site have to be taken into account, as well as special regulatory demands. The characterization is a task of the waste producer. The conditioning processes and quality checks for radioactive waste packages are part of an accredited waste management process of PSI, especially of the Section Dismantling and Waste Management. Strictly proven and accepted methods needed to be developed and enhanced for safe treatment, transport, conditioning and storage. But in the field of waste from research activities, individual and new solutions have to be found in an increasingly growing administrative environment. Furthermore, a wide variety of components, with a really large inventory of radioactive nuclides, has to be handled. And there are always surprising challenges concerning the unusual materials or the nuclide inventory. In case of the operational and dismantling radioactive accelerator waste, the existing conditioning methods are in the process of a continuous enhancement - technically and administratively. The existing authorized specifications of conditioning processes have to be extended to optimize and fully describe the treatment of the inevitably occurring radioactive waste from the accelerator facility. Additional challenges are the changes with time concerning the legal and regulatory requirements - or do we have to consider it as business as usual? This paper gives an overview of the current practices in radioactive waste management and decommissioning of the existing operational accelerator waste. (authors)

Use of CI therapy for improving motor ability after chronic CNS damage: a development prefigured by paul Bach-y-Rita.

Dr. Paul Bach-y-Rita was one of the very few investigators to maintain that the motor ability of patients with chronic stroke and other types of damages to the nervous system is modifiable, and was certainly the most influential voice articulating this view in the second part of the 20th century. In my laboratory starting in 1986, we developed a clearly specified approach to neurorehabilitation treatment, found in placebo-controlled studies to be successful in producing substantial improvement in the use of an extremity affected by chronic stroke, traumatic brain injury, cerebral palsy, and other types of central nervous system injury. The work from my laboratory therefore confirms the landmark view of Bach-y-Rita. PMID:16385641

The philosopher Paul Feyerabend and Brazilian scientists Maurício da Rocha e Silva and Newton Freire-Maia were contemporaries and lived surrounded by the fundamental dilemnas of science. The anarchist proposal of Feyerabend, then embryonic, was formulated in parallel by Rocha e Silva in his criticism of the scientific method. Two decades later, Feyerabend's ideas seemed implicitly to stimulate Newton Freire-Maia in his reflections on science. The web of interrelationships in the ideas of these three men - who never interacted - touches on central issues for Brazilian science from 1960 to 1980, a period in which the latter is consolidated in a dialogue with the nascent reflection on science and the scientific method in Brazil.

Excitation of transverse dipole and quadrupole modes in a pure ion plasma in a linear Paul trap to study collective processes in intense beams  

SciTech Connect

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

Evaluation of baseline ground-water conditions in the Mosteiros, Ribeira Paul, and Ribeira Faja Basins, Republic of Cape Verde, West Africa, 2005-06  

USGS Publications Warehouse

This report documents current (2005-06) baseline ground-water conditions in three basins within the West African Republic of Cape Verde (Mosteiros on Fogo, Ribeira Paul on Santo Ant?o, and Ribeira Faj? on S?o Nicolau) based on existing data and additional data collected during this study. Ground-water conditions (indicators) include ground-water levels, ground-water recharge altitude, ground-water discharge amounts, ground-water age (residence time), and ground-water quality. These indicators are needed to evaluate (1) long-term changes in ground-water resources or water quality caused by planned ground-water development associated with agricultural projects in these basins, and (2) the feasibility of artificial recharge as a mitigation strategy to offset the potentially declining water levels associated with increased ground-water development. Ground-water levels in all three basins vary from less than a few meters to more than 170 meters below land surface. Continuous recorder and electric tape measurements at three monitoring wells (one per basin) showed variations between August 2005 and June 2006 of as much as 1.8 meters. Few historical water-level data were available for the Mosteiros or Ribeira Paul Basins. Historical records from Ribeira Faj? indicate very large ground-water declines during the 1980s and early 1990s, associated with dewatering of the Galleria Faj? tunnel. More-recent data indicate that ground-water levels in Ribeira Faj? have reached a new equilibrium, remaining fairly constant since the late 1990s. Because of the scarcity of observation wells within each basin, water-level data were combined with other techniques to evaluate ground-water conditions. These techniques include the quantification of ground-water discharge (well withdrawals, spring discharge, seepage to springs, and gallery drainage), field water-quality measurements, and the use of environmental tracers to evaluate sources of aquifer recharge, flow paths, and ground-water residence times. In the Mosteiros Basin, measured well and spring discharge is about 220,000 cubic meters per year. For the Ribeira Paul Basin, measured well discharge, spring discharge, and ground-water seepage to springs is about 1,600,000 cubic meters per year. Ribeira Faj? Basin is the driest of the three basins with a precipitation rate of about half that of the other two basins. The only measurable ground-water discharge from this basin is from Galleria Faj?, estimated to be about 150,000 cubic meters per year. Measured discharge for all three basins does not include submarine outflow or agricultural/phreatophyte consumptive use (Paul Basin, only) and is assumed to be less than total ground-water discharge. Ground-water ages indicate that recharge to wells and springs occurred from more than 50 years ago at some locations to within the past decade at other sites. Ground water in Paul is younger than that in the other two basins, indicating that recharge generally occurred within the past 50 years. Ground water at all the dateable sites using tritium/helium in both the Mosteiros and Ribeira Faj? Basins show that recharge occurred more than 50 years before the sampling dates. Ground-water tritium/helium age dating was not possible at some sites in Mosteiros and Ribeira Faj? Basins because of the presence of helium in the aquifer derived from the mantle or aquifer matrix. However, this helium was useful for accurate age dating of the unaffected ground-water sites. Dissolved gases indicate that most ground-water recharge occurs at mid and high altitudes within all three basins; calculated recharge altitudes ranged from 700 to more than 2,000 meters. In the Mosteiros and Ribeira Faj? Basins, recharge altitudes are much higher than the wells and springs. This suggests that it may take many years for artificial recharge to result in a beneficial impact on the aquifer in areas where the agricultural projects are implemented.

Man in the Mode of Not-Being. An Ontological Study of Human Freedom in the Philosophy of Jean-Paul Sartre Developed from the Ontological Analysis of Conciousness as the Origin of the Negation  

Microsoft Academic Search

The subject of this thesis is Jean-Paul Sartre's philosophy of freedom. This involves an examination of Sartre's ontological description of the being of the world, the being-in-itself, and the being of men, the being-for-itself. Sartre's description reveals man, a conscious being, as the origin of negation. The nihilating characteristic of man' consciousness enables him to freely project ends of action

The principle of virtual power: from eliminating metaphysical forces to providing an efficient modelling tool. In memory of Paul Germain (1920-2009)  

NASA Astrophysics Data System (ADS)

In a period of a few decades, the formulation known as the principle of virtual power (PVP) has gained a prominent place among the most efficient tools in the thermomechanics of continua. Strongly marked by a "continental" (French-Italian) influence, it has successfully incorporated the basic invariances of modern continuum mechanics while capturing the spirit of twentieth-century analysis (generalized functions or distributions) in which it became synonymous of weak formulation. It proved to provide the surest and safest way to formulate complex theories of continua (so-called "generalized continuum mechanics", theory of coupled fields, etc) and approximate or generalized theories of structural members and the associated natural boundary conditions while preparing the way for the full thermomechanical formulation, providing the best setting for the proof of various mathematical theorems, and paving the way for modern numerical methods. The present contribution, illustrated by many examples of varying complexity, emphasizes the role of Paul Germain (1920-2009) in this formulation. The author, himself an active contributor and a never tired propagandist of the method, has participated in these developments during four decades and presents here his witness but critical viewpoint, highlighting the difficult points and also the esthetically pleasing ones where necessary.

Spot-Scanning Proton Radiation Therapy for Pediatric Chordoma and Chondrosarcoma: Clinical Outcome of 26 Patients Treated at Paul Scherrer Institute  

SciTech Connect

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

Application of Just War principles to nuclear war and deterrence in three contemporary theorists: Michael Walzer, Paul Ramsey, and William V. O'Brien  

SciTech Connect

The purpose of this study is to show that the Just War tradition remains applicable in the nuclear age; three contemporary just war theorists have been selected to show that this is the case: Michael Walzer, political theorist; Paul Ramsey, theologian, and William V. O'Brien, professor of international law. Each is also influenced by his Jewish, Protestant and Roman catholic tradition respectively. The focus is on the principles of proportionality and discrimination, showing how the three theorists define, validate, and apply these principles to the conduct of war as compared to the concepts of the classic Just War theorists and to those expressed in the 1983 US Catholic Bishops' Statement. This Statement reflects the influence of the three secular theorists and also of contemporary moral theory. Just War principles are applied to the uses of nuclear weapons in war-fighting and deterrence and to actual public policy. Just War principles provide policy makers with a moral basis to move beyond national egoism by directing them to be concerned about the needs of the person and about the interdependence among states principles whose validity has often been assumed but whose application has never been so necessary.

We report on the first characterization of the culturable heterotrophic bacteria of the scleractinian Madracis decactis. In addition, we characterized the culturable bacteria associated with the fireworm Hermodice carunculata, observed predating partially bleached coral colonies. Our study was carried out in the remote St. Peter and St. Paul Archipelago (SPSPA), Mid-Atlantic Ridge, Brazil. We constituted a 403 isolates collection and subsequently characterized it by means of pyrH and 16S rRNA partial sequences. We identified Photobacterium, Bacillus, and Vibrio species as members of the culturable microbiota of healthy M. decactis. V. campbellii, V. harveyi, V. communis, and V. maritimus were the most commonly found Vibrio species in healthy corals, representing more than 60 % of all vibrio isolates. Most of the vibrios isolated from the fireworm's tissues (n = 143; >90 %) were identified as V. shiloi. However, we did not recover V. shiloi from bleached M. decactis. Instead, we isolated V. communis, a novel Photobacterium species, Bacillus, Kocuria, and Pseudovibrio, suggesting a possible role of other facultative anaerobic bacteria and/or environmental features (such as water quality) in the onset of bleaching in SPSPA's M. decactis.

Geophysical evidence for the intersection of the St Paul, Cape Palmas and Grand Cess fracture zones with the continental margin of Liberia, West Africa  

USGS Publications Warehouse

PUBLISHED reconstructions of Gondwana continent1 (Fig. la) show a gap in fit near the junction of the Americas and Africa. To study this critical area, the Unitedgeo I made geophysical measurements and collected rock samples across the continental margin of Liberia (USGS-IDOE cruise leg 5) in November 1971. Figure Ib indicates the location of the 5,400 km of ship track on a generalised bathymetric map2. We shall discuss the data in detail elsewhere. Here we present the evidence for the existence of three fracture zones, two of which have not been reported previously, intersecting the continental margin at the north end of the South Atlantic, which remained closed probably until Cretaceous time. We suggest that Precambrian structures on the African continent controlled the location of these fracture zones. Figure Ic compares gravity and magnetic profiles and interpretations of the seismic profiles for three selected lines (27, 30 and 34) crossing the Grand Cess, Cape Palmas and St Paul fracture zones, respectively. ?? 1974 Nature Publishing Group.

Effects of rain gardens on the quality of water in the Minneapolis-St. Paul metropolitan area of Minnesota, 2002-04  

USGS Publications Warehouse

Rain gardens are a popular method of managing runoff while attempting to provide aesthetic and environmental benefits. Five rain-garden sites in the Minneapolis - Saint Paul metropolitan area of Minnesota were instrumented to evaluate the effects of this water-management system on surface and subsurface water quality. Most of these sites were in suburban locations and frequently in newer developments. Because of this they were affected by changing hydrology during the course of this study. Less-than-normal precipitation during much of the study may have resulted in samples that may not be representative of normal conditions. However, the resulting data indicate that properly designed rain gardens enhance infiltration and can reduce concentrations of dissolved ions relative to background conditions. The runoff events in one rain garden and several runoff events in the other rain gardens produced no sampled overflow during this study because the gardens captured all of the inflow, which subsequently infiltrated beneath the land surface, evaporated, or transpired through garden vegetation. Where measured, overflow had reduced concentrations of suspended solids and most nutrient species associated with particulate material, as compared to inflow. Many of these materials settle to the bottom of the rain garden, and some nutrients may be assimilated by the plant community. Site design, including capacity relative to drainage area and soil permeability, is an important consideration in the efficiency of rain-garden operation. Vegetation type likely affects the infiltration capacity, nutrient uptake, and evapotranspiration of a rain garden and probably the resulting water quality. The long-term efficiency of rain gardens is difficult to determine from the results of this study because most are still evolving and maturing in relation to their hydrologic, biologic, and chemical setting. Many resource managers have questioned what long-term maintenance will be needed to keep rain gardens operating effectively. Additional or continued studies could address many of these concerns.

Characterization of ground-water discharge from bedrock aquifers to the Mississippi and Minnesota Rivers at three areas, Minneapolis-St. Paul area, Minnesota  

USGS Publications Warehouse

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

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

PubMed

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

Cancer, viruses, and mass migration: Paul Berg's venture into eukaryotic biology and the advent of recombinant DNA research and technology, 1967-1980.  

PubMed

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

Configuration of water table and distribution of downward leakage to the Prairie du Chien-Jordan Aquifer in the Minneapolis-Saint Paul metropolitan area, Minnesota  

USGS Publications Warehouse

The configuration of the water table as plotted at a contour interval of 20 feet (6 metres) on quadrangle maps (scale 1:2,500) of the Minneapolis-Saint Paul metropolitan area. Control points used for mapping were water levels in wells, lakes and sloughs, and places where topographic contours cross perennial streams. A computer program, using a variation of Darcy's law, was developed to determine distribution of 1) downward leakage to the Prairie du Chien-Jordan aquifer under steady-state conditions, using estimated vertical-hydraulic conductivity values for overlying materials; 2) calculated vertical hydraulic conductivity values, assuming uniform leakage to the aquifer; and 3) additional leakage to the aquifer resulting from increased pumpage during the summer. For data determination and data input to the computer program, the area was gridded into units of 1-minute longitude by 1-minute latitude, about 600 acres (243 hectares) per unit. Previous work estimated the increased summer pumpage (1971) of ground water to be 127 million gallons (481x106 litres) per day. Calculations, made Within the limits of governing assumptions, indicate that 10 to 20 percent of increased summer pumpage is derived from increased leakage. Most of the remainder is probably from captured natural discharge and induced recharge from major streams within the influence of summer cones of depression. Based on available data and estimates of vertical hydraulic conductivity for geologic units, major leakage to the Prairie du Chien-Jordan aquifer is indicated to occur in formation subcrop areas, especially where these areas are. overlain by the most permeable glacial drift.

Paul Bunyan's Brachistochrone and Tautochrone  

SciTech Connect

In this paper we concern ourselves with modified versions of the traditional brachistochrone and tautochrone problems. In the modified version of each problem the constant gravity model is replaced with an attractive inverse square law, consequently we name these the 1/{tau}{sup 2} brachistochrone and 1/{tau}{sup 2} tautochrone problems. With regard to the 1/{tau}{sup 2} brachistochrone problem, we show that the shape of the minimizing curve is formally constructed from an infinite series of elliptic integrals, and we use a numerical optimal control technique to generate the trajectories. The 1/{tau}{sup 2} tautochrone problem is solved using fraction calculus together with Lagrange's rule for tautochronous curves

Characterization of microbial populations across geochemical and lithological boundaries in urban lake sediments under environmental change in Minneapolis-St. Paul  

NASA Astrophysics Data System (ADS)

The characterization of microbial communities within urban lake sediments may offer a promising method to observe changes in lake geochemistry due to human impact. By mapping the abundances and diversity of microorganisms through the uppermost meter of sediment in three distinctive Minneapolis-St. Paul lakes (Brownie Lake and Twin Lake, both meromictic, and oligomictic Lake McCarrons) using 16S rRNA characterization, our aim was to observe changes in microbial populations across steep geochemical and lithological gradients. Lake McCarrons underwent a process of eutrophication and a shift to bottom water anoxia beginning around 1910 due mostly to agricultural run-off. This shift greatly increased the preservation potential of seasonal sedimentation and finely laminated varve accumulation. The onset of meromixis in Brownie Lake in ~1915 is abrupt and has been attributed to a sudden drop in water level. Twin Lake is perennially meromictic due to the topography of the watershed. The three lakes were sampled by collecting freeze cores in July, 2012 (McCarrons, Brownie) and February, 2013 (Twin) at the deepest locations beneath anoxic to hypoxic bottom waters. The cores were then subsampled with high resolution techniques at places of interest: within individual lamina, across mass flow deposits, and near the onset of laminae preservation (beginning of oxygen-depleted bottom waters). Terminal Restriction Fragment Length Polymorphism (T-RFLP) allows for comparison of the microbial assemblages throughout the sediment columns of each lake and from lake to lake, with a focus on the horizons mentioned previously. The microbial assemblages present in specific horizons are often introduced via sedimentation and are partially derived from community composition at the time of sedimentation. T-RFLP analyses are complemented by mineralogical and lithological descriptions. The lakes have each been subject to their own set of variables and inputs. Brownie Lake contains high levels of Fe and Mn (measured up to 78 and 6 mg/l in bottom waters, respectively, US EPA STORET). The ecology of McCarrons has been greatly disturbed most recently when the lake was targeted by a 2004 aluminum sulfate treatment to counteract high phosphorous levels. Twin Lake has mass flow deposits nearly 5 cm thick, similar to turbidites, likely caused by increased sedimentation from large housing developments on the lake shores. The microbial community in each of the lakes is impacted by these distinct parameters. This study examines variability in microbial community assemblages through time and space within these lake sediments. Changes seen in the ecology of the communities are related to changes in chemical and physical parameters, namely, shifts in lithology and sediment accumulation via the onset of meromixis. Freeze coring exceptionally allows super-high resolution subsampling techniques to identify differences across geochemical gradients and between individual seasonal laminae within each lake and from lake to lake.

[The Impartiality of Ignorance? - A Controversy between Paul Julius Möbius and Julius Wagner-Jauregg on the Symptoms of Reanimated Persons after a Suicide Attempt through Self-Hanging].

Introduction: Between 1891 and 1893 the famous Austrian and German neuropsychiatrists Julius Wagner-Jauregg and Paul Julius Möbius disputed in leading German and Austrian medical journals about mental and physiological changes and symptoms in people who after strangulation could be revived in time to survive. Their dispute even touched personal issues. Methods: For the study, the original sources were studied and contrasted with relevant secondary sources. Results: The dispute was mainly about two opposing concepts: On the one hand, Wagner-Jauregg supported an organic, neurological concept; on the other hand a psychoreactive-symptoms concept represented by Möbius and elaborated by him first in his concept of hysteria. Discussion: The study elaborates these factual differences in completely different approaches to psychiatry and - at least in the case of Möbius - how a medical theory was embedded into a pre-existing philosophical system. Consequences: The dispute studied discusses a philosophical problem which has remained incompletely understood until the present day - the relationship of body and mind. Hence the study on this dispute is more than just an interesting aspect in the history of sciences, but rather the illustration of a meeting of two opponents in a still relevant discussion.

On Launching the First Principles Atomic Theory Using Common Sense Pressure- Temperature Dynamism Analysis in Material Universe Vis a Vis Theories of Bohr (Atomic Theory) and Pauling (Chemical Bonding Theory)  

NASA Astrophysics Data System (ADS)

Several of my recent papers in various areas of scientific and engineering investigations have been found to validate famous atomic theory of Bohr and chemical bonding theory of Pauling. In view of this, I thought of composing a paper to go alongside original Bohr and prior Rutherford work of attempting to launch an atomic (theory) picture using a special technique I have been following in these mentioned papers viz. pressure temperature dynamics in expanding - contracting material Universe. In expanding contracting Universe, at various times, pressure and temperature gradients are created that give rise to cooling at some places where condensation (from gas to liquid to solid) of matter takes place and heating at some other where disintegration (from solid to liquid to gas) to smaller matter (by burning etc) takes place. In locations where condensation and solidification occurs, higher density or gravity starts accumulating at centers of these condensing matters and in locations where gasifying occurs gravity vanishes to smaller and smaller values. The consequences of such phenomena is "mostly" similar in small as well as large scale of size or dimension of matter and Universe space-time concerned. Since gravity gradients formation in distributed [large] space-time, launches net orbital positional rotatory motions of smaller scattered masses around and in between such larger gravity centers (due to net forces on each smaller scattered masses), similar picture also occurs inside a smaller solid or liquid or gaseous mass, only differing in mechanism a little bit with the phase state of the mass (solid, liquid or gas) concerned.

Evidence-based practice in Steeltown: a good start on needed cultural change.  

PubMed

At the Canadian Health Services Research Foundation we talk a lot about the need to improve the 'receptor capacity' for research in the health sector (Canadian Health Services Research Foundation 2000). To create a demand for research as well as a supply of it. To encourage and assist clinicians, managers and policymakers in the health system to pull research from academe with as much fervor as applied researchers now bring to publishing it. Browman, Snider and Ellis have done more than talk about and encourage these things - they have implemented them at their own workplace in Hamilton. Their formula is:1. Design a policy-learning forum (Clinical Policy Committee'), where the use of available research is encouraged and expected 2. Create champions (knowledge stewards') responsible for marshalling and presenting the evidence. 3. Provide rules (negotiation') for the dialogue between the operational implications of the research and its budgetary reality. 4. Use story telling to uncover local implementation barriers and make tacit knowledge explicit. The approach is reminiscent of political scientist Paul Sabatier's description of the circumstances under which policy learning occurs (Sabatier and Jenkins-Smith 1993) and Brown and Duguid's compelling outline of how information permeates corporate structures (Brown and Duguid 2000). Sabatiers advocacy coalition framework highlights the optimal conditions for learning as: balanced coalitions (in this case, of those behind the research and those behind the finances), enough resources for each side to produce a steady flow of information, an organized forum for debate and clear rules of engagement. In 'The Social Life of Information, 'Brown and Duguid highlight the extent to which modern corporations often leave unrecognized and under-utilized their greatest asset - the tacit knowledge accumulated by each employee over his or her career. They, too, recommend storytelling as a way to liberate this knowledge for wider use. Browman and colleagues 'practical realization of Sabatier' advocacy coalition framework and Browns social view of information is refreshing on a number of levels. PMID:12811084

The male facial skeleton is larger and more angular than that of the female. The male skull has bossing in the area of the frontal sinuses (there is bossing even without presence of the sinuses--5% of people do not have a frontal sinus) and a small flat spot in the mid forehead between the areas of bossing and usually slightly above them. Also there is bossing in the superior lateral orbital angle. The chin on an average basis is 17% vertically higher in the male and there is more fullness laterally. The angle of the mandible is larger inferioro-posteriorly and generally flares out more laterally. The oblique line is fuller in the male. To date 6 males who have wanted to have a more masculine face have been operated on forehead, chin, and mandible. All 6 have done well and without complications. Their acceptance of this surgery has been great. PMID:22123544

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

NASA Astrophysics Data System (ADS)

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

Case Studies in Science Education: PaulÂGrade 6  

NSDL National Science Digital Library

After an initial lesson eight weeks earlier, this sixth grade class continues to work on structures. Their culminating project, which the teacher uses as a performance assessment, requires them to build a bridge designed within certain constraints: a car must be able to go up and over the bridge as well as under it, and the materials, which the student groups request, must "cost" as little as possible. The segment shows students working on the bridge, identifying problems (such as a slope that is too steep) in a trial run, the final demonstrations of the bridges, and the class discussion of what students learned from the design experience. Referring to the trial runs, the teacher asks students such questions as what they had to change to perfect their bridges and why they chose the materials they did.

Essential Paul Meehl lessons for personality assessment psychology.  

PubMed

The author presents four essential Meehl lessons for personality assessment. First, Meehl's particular form of the integration of science and practice is described. Second, by outlining Meehl's Hedonic Capacity conjecture, Meehl's contribution to the inclusion of personality individual differences in generating the full clinical picture and in planning treatment is recognized. The third Meehl lesson is on the nature and importance of theory in test development and application programs. The fourth Meehl lesson is a more general epistemological lesson for psychology. Meehl's role in destroying the fantasy of an easy methodological formula for a scientific psychology is described. His program of taxometric research is shown to be an example of demanding greater material implications from theory. Meehl's corroboration index is described and contrasted with the p value of statistical significance testing. PMID:16041783

Managing for the next big thing. Interview by Paul Hemp.  

PubMed

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

These were stubborn, egotistical, tenacious, work-oriented people who could not be deterred by obstacles of any sort. They exemplify the unbreakable spirit required to achieve greatness. A surprising finding is the extent of hostility they all aroused from closed-minded people in society who were upset by the implications of their new ideas. It is hoped that this essay will help to stiffen the resolve of creative men and women who can expect to confront fervent opposition from others in society regardless of the value of their discoveries.

A physical basis for Pauling's definition of bond strength  

SciTech Connect

The average strength, s, of the bonded interactions comprising a cation containing oxide anion coordination polyhedron and the value of the electron density, „(rc), at the bond-critical points are inversely correlated with bond length. in each case, the observed bond lengths, r, were modeled with power-law expressions defined in terms of s/r and „(rc)/r, respectively, where r is the periodic table row number of the cation involved in the bonded interaction. on the basis of the close connection between bond strength and the value of the electron density at the bond-critical point, we conclude that bond strength is a direct measure of bond type; the greater its value, the greater the localization of electron density in the binding region and the greater the shared-electron covalent character of the bonded interaction.

Relief of intractable cancer pain by human chromaffin cell transplants: experience at two medical centers.  

PubMed

In addition to its possible role as a replacement source in CNS degenerative diseases, neural transplantation may be used to augment the normal production of neuroactive substances. Our laboratory at the University of Illinois at Chicago has shown, in both acute and chronic pain models, that transplantation of adrenal medullary tissue or isolated chromaffin cells into CNS pain modulatory regions can reduce pain sensitivity in rodents. Chromaffin cells were chosen as the donor source since they produce high levels of both opioid peptides and catecholamines, substances which reduce pain sensitivity when injected locally into the spinal subarachnoid space. The analgesia produced by these transplants probably results from the release of both opioid peptides and catecholamines since it can be blocked or attenuated by both opiate and adrenergic antagonists. Studies indicate that even over long periods there is no apparent development of tolerance. Promising results have been obtained in preliminary clinical studies using allografts of adrenal medulla to relieve cancer pain. This clinical review encompasses results at two Medical Centers-University of Illinois at Chicago and University Paul Sabatier, Toulouse, France-in assessing efficacy of subarachnoid adrenal medullary transplantation for alleviating cancer pain. Our clinical and autopsy data strongly support our previous laboratory studies, i.e., that chromaffin cell transplants into the subarachnoid space represent a promising new approach to the alleviation of chronic pain. It is suggested that further clinical studies are now warranted. PMID:9090640

Direct CO2-Methanation of flue gas  

NASA Astrophysics Data System (ADS)

Already discovered by Paul Sabatier in 1902 the Hydrogenation according to CO2 + 4H2 ->CH4 + 2H2O nowadays is discussed in the course of the "Power-to-Gas" approach to utilize excess energy from renewable electricity generation in times of oversupply of electricity. We investigate the behavior of this process in a simulated flue gas atmosphere of conventional base load power plants, which could be used as constant sources of the reactant CO2. In relation to an approach related to carbon capture and cycling, the conversion of CO2 directly from the flue gas of a conventional power plant is a new aspect and has several advantages: The conversion of CO2 into methane could be integrated directly into the combustion process. Even older power plants could be upgraded and used as a possible source for CO2, in the same sense as the amine cleaning of flue gas, as a post combustion process. Further, waste heat of the power plant could be used as process energy for the catalytic reaction. Therefore the influence of different flue gas compositions such as varying contents of nitrogen and residual oxygen are tested in a laboratory scale. The heterogeneous catalysis process is investigated with regard to conversion rates, yield and selectivity and long-term stability of the Ni-catalyst. Also the influence of typical contaminations like SO2 is investigated and will be presented.

Neutral Buoyancy Test NB-15, Scientific Airlock Contingency Operations - test subject Astronaut Paul  

NASA Technical Reports Server (NTRS)

Once the United States' space program had progressed from Earth's orbit into outerspace, the prospect of building and maintaining a permanent presence in space was realized. To accomplish this feat, NASA launched a temporary workstation, Skylab, to discover the effects of low gravity and weightlessness on the human body, and also to develop tools and equipment that would be needed in the future to build and maintain a more permanent space station. The structures, techniques, and work schedules had to be carefully designed to fit this unique construction site. The components had to be lightweight for transport into orbit, yet durable. The station also had to be made with removable parts for easy servicing and repairs by astronauts. All of the tools necessary for service and repairs had to be designed for easy manipulation by a suited astronaut. And construction methods had to be efficient due to limited time the astronauts could remain outside their controlled environment. In lieu of all the specific needs for this project, an environment on Earth had to be developed that could simulate a low gravity atmosphere. A Neutral Buoyancy Simulator (NBS) was constructed by NASA Marshall Space Flight Center (MSFC) in 1968. Since then, NASA scientists have used this facility to understand how humans work best in low gravity and also provide information about the different kinds of structures that can be built. With the help of the NBS, building a space station became more of a reality. In a joint venture between NASA/Langley Research Center in Hampton, VA and MSFC, the Assembly Concept for Construction of Erectable Space Structures (ACCESS) was developed and demonstrated at MSFC's NBS. The primary objective of this experiment was to test the ACCESS structural assembly concept for suitability as the framework for larger space structures and to identify ways to improve the productivity of space construction. Pictured is a demonstration of ACCESS.

Molecular Toxicology (by P. David Josephy, with Bengt Mannervik and Paul Ortiz de Montellano)  

NASA Astrophysics Data System (ADS)

Oxford University Press: Oxford and New York, 1997. xv + 368 pp. ISBN 0-19-509340-2. $56.00. This well-written book presents concepts of toxicology from a chemical, biochemical, and molecular biological perspective and serves as a welcome companion to other books on toxicology, which tend to have as a basis the characterization and quantification of toxic responses. This mechanistic approach should be particularly appealing to scientists with a strong chemical background. The book is an outgrowth of a course in molecular toxicology taught at the University of Guelph by the author, and it fills a much-needed niche as a textbook for a course focusing on biochemical mechanisms of toxicology. The clientele for such a course is advanced undergraduates or graduate students with a strong background in biochemistry, bioorganic chemistry, toxicology, or pharmacology.

Artificial recharge through a well in fissured carbonate rock, west St. Paul, Minnesota  

USGS Publications Warehouse

The Prairie du Chien Group was injected with 2,754,000 gallons (368,200 cubic feet), or 10,430 cubic metres, of municipally treated water at about 100 gallons per minute (13.4 cubic feet per minute), or 6.3 litres per second, for 20 days. The injection-pipe system was designed to utilize pipe friction rather than a remote-controlled valve in the well to maintain positive pressure and eliminate air entrainment in the injection water and the escape cf dissolved gasses from the water. During the 20-day injection period the temperature of the injection water declined gradually from 15.0? to 11.2?C, and the flow rate decreased from 108 to 90 gallons per minute (6.8 to 5.7 litres per second). Analyses of test data were, in some instances, based upon hydrologic judgement as well as observations. Results of aquifer tests before and after injections indicated that the transmissivity had decreased 18 percent during the intervening injection periods; however, the specific capacity remained the same, indicating no change in transmissivity during pumping. Analysis of water-level changes in observation wells during injection indicated a reduction in transmissivity of more than 50 percent; however, the specific capacity of the injection well decreased only about 5 percent during injection. A comparison of water-level changes with the discharge or recharge rates of the three tests showed that the water-level changes in the two observation wells tapping the Prairie du Chien Group during the injection test were greater than those projected from the two aouifer pumping tests. The deviations in the water-level changes and in the analysis of aquifer-test data indicate that the methods used to analyze data from these wells may not be wholly applicable, inasmuch as anisotropic and nonhomogeneous conditions prevail in at least the Prairie du Chien part of the aquifer. The native water and the injected water averaged 0.8 and 25 milligrams per litre chloride, respectively. The chloride, utilized as a tracer, showed that the injected water was detected only in the lower part of the nearest observation well, 99 feet (30.2 metres) from the injection well. The chemistry of the water and the rock formation showed little likelihood of plugging of the recharge well by chemical precipitation. Microbiological phenomena apparently did not become a significant factor in the recharge test. The hydraulic gradient of the aquifer in October and December 1971 (before and after injection) was estimated to be N. 36? E., 0.0013, and N. 39? E., 0.0012, respectively, on the basis of measurements of water levels in the three wells in the Prairie du Chien Group. The single-well tracer-dilution method of calculation showed a hydraulic gradient of 0.0016. A longitudinal dispersivity of 280 feet (85 metres) was calculated. Such a value of dispersivity is typical of fractured reservoirs and shows that the Prairie du Chien Group is a heterogeneous aquifer. The injection test demonstrated that it is hydrologically feasible to recharge the Prairie du Chien Group and the Jordan Sandstone artificially through wells completed in the Prairie du Chien Group. The fissures in the Prairie du Chien Group act as conduits through which water spreads. The water passes into the Jordan Sandstone from the Prairie du Chien over a larger area than it would if it were injected directly into the Jordan.

Enaminones 12. An explanation of anticonvulsant activity and toxicity per Linus Pauling's clathrate hypothesis.  

PubMed

The x-ray crystal structure of 3-((5-methylisoxazol-3-yl)amino)-5-methylcyclohex-2-enone (12b) and 3-((5-methylisoxazolyl-3-yl)amino)-5,5-dimethylcyclohex-2-enone (12c) were determined and correlated to their anticonvulsant activity in mice and rats. A hypothesis for the toxicity of the analogs are advanced. In addition, a series of 5-methyl-N-(3-oxocyclohex-1-enyl)-isoxazole-3-carboxamides were synthesized and evaluated for anticonvulsant activity. These compounds were compared to the activity of the corresponding amino and aminomethyl enaminones. Additional investigation involved the synthesis and evaluation of a trifluoromethyl analog of the active isoxazole tert-butyl 4-(5-methisoxazol-3-yl-amino)-6-methyl-2-oxo-cyclohex-3-ene carboxylate (4f).

How Linus Pauling Finally Got the Priestley Medal of the American Chemical Society  

NASA Astrophysics Data System (ADS)

Late in 1981 I started firming up plans for a symposium marking the 250th anniversary of the birth of Joseph Priestley in 1733. The symposium was scheduled for the 1983 Fall Meeting of the American Chemical Society to be held in Washington D. C. Because of Priestley's wide-ranging interests and activities, the speakers were to include not only chemists and historians but also a political scientist, a grammarian, and a Unitarian minister. The closing session was to open with Melvin Calvin speaking on "Artificial Photosynthesis"-a phenomenon Priestley was the first to observe, albeit somewhat confusedly. Next came Fred Basolo, then president of the American Chemical Society, on "Synthetic Oxygen Carriers of Biological Interest"-Priestley had abeen among the first to remark on the role of dephlogisticated air (oxygen) in the interconversion of venous and arterial blood.

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

Materials researches at the Paul Scherrer Institute for developing high power spallation targets  

NASA Astrophysics Data System (ADS)

For the R&D of high power spallation targets, one of the key issues is understanding the behavior of structural materials in the severe irradiation environments in spallation targets. At PSI, several experiments have been conducted using the targets of the Swiss spallation neutron source (SINQ) for studying radiation damage effects induced by high energy protons and spallation neutrons. As well, experiments have been performed to investigate liquid lead-bismuth eutectic (LBE) corrosion and embrittlement effects on T91 steel under irradiation with 72 MeV protons. In this paper, an overview will be given showing a selection of results from these experiments, which include the mechanical properties and microstructure of ferritic/maretensitic (FM) steels (T91, F82H, Optifer etc.) and austenitic steels (EC316LN, SS 316L, JPCA etc.) irradiated to doses higher than ever attained by irradiation in a spallation environment, and the behaviors of T91 irradiated with 72 MeV protons in contact with flowing LBE.

The nEDM experiment at the Paul Scherrer Institute, Switzerland  

NASA Astrophysics Data System (ADS)

A permanent electric dipole moment of the neutron would be a sign of combined charge-conjugation and parity (CP) violation. The prediction of the Standard Model (SM) of particle physics for the neutron EDM is about 10-31 e cm and at the same time CP violation in the SM is insufficient in order to explain the observed baryon asymmetry of the universe (BAU). Several extensions of the SM aiming at explaining the observed BAU also predict values for the neutron EDM up to just below the current best experimental limit of dn <2.9×10-26e cm (90%C.L.) [1]. Our collaboration aims at improving the experimental sensitivity to the nEDM by two orders of magnitude which will probe a large part of the parameter space for these models.

Pauling's Ionicity and Charge-Density Waves in Layered Transition-Metal Dichalcogenides  

Microsoft Academic Search

The crystal distortions commonly observed in the layered transition-metal dichalcogenides have been attributed to a Fermi-surface instability, i.e., a charge-density wave. I find that the temperatures of these distortions correlate with the ionicity of the metal-chalcogen bond. This results suggests that these distortion temperatures can be specified without knowing the details of the Fermi surface.

Groundwater Resources of Ribeira Paul Basin, Island of Santo Antao, Cape Verde, West Africa  

USGS Publications Warehouse

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

Discovery of a magnetic field in the B pulsating system HD 1976  

NASA Astrophysics Data System (ADS)

Aims: A magnetic field can have a strong impact on the evolution of a binary star. However, only a dozen magnetic OB binaries are known as of today and are available to study this effect, including some very few magnetic pulsating spectroscopic OB binaries. We checked for the presence of a magnetic field in the B5IV hierarchical triple system HD 1976 with spectropolarimetric data obtained with Narval at the Bernard Lyot Telescope (TBL). Methods: We used orbital parameters of HD 1976 available in the literature to disentangle the Narval intensity spectra. We computed Stokes V profiles with the least squares deconvolution technique to search for magnetic signatures. We then derived an estimate of the longitudinal magnetic field strength for each observation and for various line lists. Results: Our disentangling of the intensity spectra shows that HD 1976 is a double-lined spectroscopic (SB2) binary, the lines of the secondary component are about twice as broad as those of the primary component. We did not identify the third component. Moreover, we find clear magnetic signatures in the spectropolarimetric measurements of HD 1976 that seem to be associated with the primary component. We conclude that HD 1976 is a magnetic slowly pulsating double-lined spectroscopic binary star with an undetected third component. It is the second such example known (the other is HD 25558). Based on observations obtained at the Telescope Bernard Lyot (USR5026) operated by the Observatoire Midi-Pyrénées, Université de Toulouse (Paul Sabatier), Centre National de la Recherche Scientifique of France.

Spot Scanning Proton Therapy in the Curative Treatment of Adult Patients With Sarcoma: The Paul Scherrer Institute Experience  

SciTech Connect

Purpose: To assess the safety and efficacy of spot scanning proton beam therapy (PT) in the curative treatment of soft-tissue sarcoma (STS) in adults patients. Patients and Methods: We identified 13 STS patients treated with PT between July 1998 and May 2005 in our institutional database. Tumor histology varied with the most common histologic subtypes including liposarcoma and peripheral nerve sheet tumor. All tumors were located in vicinity of critical structures, such as the spinal cord, optic apparatus, bowel, kidney, or bowel. Of the patients, 6 and 5 patients received PT either as adjuvant therapy for non-R0 resection or for recurrence, respectively. Two patients received radical PT for unresectable disease. The median prescribed dose was 69.4 CGE (CGE = proton Gy x 1.1)-Gy (range, 50.4-76.0) at 1.8 to 2 CGE-Gy (median, 1.9) per fraction. Pre-PT anthracycline-based chemotherapy was delivered to 3 patients only. No patient has been lost to follow-up (median 48.1 months, range, 19.1-100.7 months). Results: Of the 13 patients, all but 2 patients were alive. Local recurrence developed in 3 (23%) patients. The administered dose to these patients was {<=}60 Gy-CGE. Distant control was achieved in all but 2 patients (lung metastasis), 1 of whom presented with a concomitant local recurrence. The 4-year local control and metastasis-free survival rates were 74.1% and 84.6%, respectively. Late grade {>=}2 toxicity was observed in only 2 patients. Conclusions: Spot scanning PT is an effective and safe treatment for patient with STS in critical locations. The observed toxicity rate was acceptable.

Graphic and analytical methods for assessment of streamwater quality : Mississippi River in the Minneapolis-St Paul metropolitan area, Minnesota  

USGS Publications Warehouse

Historical records were analyzed to determine effects of population, pollution-control strategy, and other factors on water quality of the Mississippi River. Isopleths of DO (dissolved oxygen) concentrations and lines of equal stream temperature indicated periodic data could be used to guide sampling of certain critical conditions in time and space. Long-term records revealed generally mixed changes in quality in the Mississippi River. Several mean-time series were used to show seasonal variation in water quality and effects of initiation of wastewater treatment in 1938. Kendall 's tau statistical test indicated a significant increase in DO in the upper reach of the river during the period of record. If only the post-1938 period is considered, DO conditions remained fairly constant below the metropolitan plant and biochemical oxygen demand increased throughout the main-stem reach. Significant trends in stream temperature were indicated for winter periods using Kendall 's tau procedure. The Mann-Whitney statistical test gave estimates of a 98-percent confidence interval of the magnitudes of change. (Woodard-USGS)

Spot Scanning-Based Proton Therapy for Intracranial Meningioma: Long-Term Results From the Paul Scherrer Institute  

SciTech Connect

Background: To assess the long-term clinical results of spot scanning proton therapy (PT) in the treatment of intracranial meningiomas. Patients and Methods: Thirty-nine patients with meningioma (histologically proven 34/39) were treated with PT between July 1997 and January 2010. Thirty-two (82.1%) patients were treated as primary treatment (exclusive PT, n = 8; postoperative PT, n = 24). Mean age was 48.3 {+-} 17.9 years and 32 (82.1%) patients had skull base lesions. For patients undergoing surgery, 24 patients had a diagnosis of World Health Organization (WHO) Grade I and 10 of a WHO Grade II/III meningioma, respectively. The female-to-male ratio was 3.3. The median administered dose was 56.0 Gy (relative biologic effectiveness [RBE]) (range, 52.2-66.6) at 1.8-2.0 Gy (RBE) per fraction. Gross tumor volume (GTV) ranged from 0.76 to 546.5 cm{sup 3} (median, 21.5). Late toxicity was assessed according to Common Terminology Criteria for Adverse Events version 3.0. Mean follow-up time was 62.0 months and all patients were followed for >6 months. Results: Six patients presented with tumor recurrence and 6 patients died during follow-up, of which 4 of tumor progression. Five-year actuarial local control and overall survival rates were 84.8% and 81.8%, respectively, for the entire cohort and 100% for benign histology. Cumulative 5-year Grade {>=}3 late toxicity-free survival was 84.5%. On univariate analysis, LC was negatively influenced by WHO grade (p = 0.001), GTV (p = 0.013), and male gender (p = 0.058). Conclusions: PT is a safe and effective treatment for patients with untreated, recurrent, or incompletely resected intracranial meningiomas. WHO grade and tumor volume was an adverse prognostic factor for local control.

A high-precision segmented Paul trap with minimized micromotion for an optical multiple-ion clock  

NASA Astrophysics Data System (ADS)

We present a new setup to sympathetically cool 115In+ ions with 172Yb+ for optical clock spectroscopy. A first prototype ion trap made of glass-reinforced thermoset laminates was built, based on a design that minimizes axial micromotion and offers full control of the ion dynamics in all three dimensions. We detail the trap manufacturing process and the characterization of micromotion in this trap. A calibration of the photon-correlation spectroscopy technique demonstrates a resolution of 1.1 nm in motional amplitude of our measurements. With this method, we demonstrate a sensitivity to systematic clock shifts due to excess micromotion of along the direction of the spectroscopy laser beam. Owing to our on-board filter electronics on the ion trap chips, no rf phase shifts could be resolved at this level. We measured rf fields over a range of 400 ?m along the ion trap axis and demonstrated a region of 70 ?m where an optical frequency standard with a fractional inaccuracy of ?1 × 10-18 due to micromotion can be operated.

Volcano plots in hydrogen electrocatalysis - uses and abuses  

PubMed Central

Summary Sabatier’s principle suggests, that for hydrogen evolution a plot of the rate constant versus the hydrogen adsorption energy should result in a volcano, and several such plots have been presented in the literature. A thorough examination of the data shows, that there is no volcano once the oxide-covered metals are left out. We examine the factors that govern the reaction rate in the light of our own theory and conclude, that Sabatier’s principle is only one of several factors that determine the rate. With the exception of nickel and cobalt, the reaction rate does not decrease for highly exothermic hydrogen adsorption as predicted, because the reaction passes through more suitable intermediate states. The case of nickel is given special attention; since it is a 3d metal, its orbitals are compact and the overlap with hydrogen is too low to make it a good catalyst.

Seismic and spectroscopic characterization of the solar-like pulsating CoRoT target HD 49385  

NASA Astrophysics Data System (ADS)

Context. The star HD 49385 is the first G-type solar-like pulsator observed in the seismology field of the space telescope CoRoT. The satellite collected 137 days of high-precision photometric data on this star, confirming that it presents solar-like oscillations. HD 49385 was also observed in spectroscopy with the NARVAL spectrograph in January 2009. Aims: Our goal is to characterize HD 49385 using both spectroscopic and seismic data. Methods: The fundamental stellar parameters of HD 49385 are derived with the semi-automatic software VWA, and the projected rotational velocity is estimated by fitting synthetic profiles to isolated lines in the observed spectrum. A maximum likelihood estimation is used to determine the parameters of the observed p modes. We perform a global fit, in which modes are fitted simultaneously over nine radial orders, with degrees ranging from ? = 0 to ? = 3 (36 individual modes). Results: Precise estimates of the atmospheric parameters (Teff, [M/H], log g) and of the ? sin i of HD 49385 are obtained. The seismic analysis of the star leads to a clear identification of the modes for degrees ? = 0,1,2. Around the maximum of the signal (? ? 1013 ?Hz), some peaks are found significant and compatible with the expected characteristics of ? = 3 modes. Our fit yields robust estimates of the frequencies, linewidths and amplitudes of the modes. We find amplitudes of ~5.6 ± 0.8 ppm for radial modes at the maximum of the signal. The lifetimes of the modes range from one day (at high frequency) to a bit more than two days (at low frequency). Significant peaks are found outside the identified ridges and are fitted. They are attributed to mixed modes. Based on data obtained from the CoRoT (Convection, Rotation and planetary Transits) space mission, developed by the French Space agency CNES in collaboration with the Science Programs of ESA, Austria, Belgium, Brazil, Germany and Spain.Based on data obtained using the Télescope Bernard Lyot at Observatoire du Pic du Midi, CNRS and Université Paul Sabatier, France.

Magnetic field topology of the unique chemically peculiar star CU Virginis  

NASA Astrophysics Data System (ADS)

Context. The late-B, magnetic, chemically peculiar star CU Vir is one of the fastest rotators among the intermediate-mass stars with strong fossil magnetic fields. It shows a prominent rotational modulation of the spectral energy distribution and absorption line profiles due to chemical spots and exhibits a unique, strongly beamed variable radio emission. Aims: Little is known about the magnetic field topology of CU Vir. In this study, we aim to derive detailed maps of the magnetic field distribution over the surface of this star for the first time. Methods: We use high-resolution spectropolarimetric observations covering the entire rotational period. These data are interpreted using a multi-line technique of least-squares deconvolution (LSD) and a new Zeeman Doppler imaging code, which is based on detailed polarised radiative transfer modelling of the Stokes I and V LSD profiles. This new magnetic inversion approach relies on the spectrum synthesis calculations over the full wavelength range that is covered by observations and does not assume that the LSD profiles behave as a single spectral line with mean parameters. Results: We present magnetic and chemical abundance maps derived from the Si and Fe lines. Mean polarisation profiles of both elements reveal a significant departure of CU Vir's magnetic field topology from the commonly assumed axisymmetric dipolar configuration. The field of CU Vir is dipolar-like but clearly non-axisymmetric, showing a large difference in the field strength between the regions of opposite polarity. The main relative abundance depletion features in both Si and Fe maps coincide with the weak-field region in the magnetic map. Conclusions: The detailed information on the distorted dipolar magnetic field topology of CU Vir provided by our study is essential for understanding chemical spot formation, radio emission, and rotational period variation of this star.

How an Anglo-American methodology took root in France.  

PubMed

French organic chemistry had a strong nationalistic bent in the immediate aftermath to World War II. It continued to bask in the glow of the pre-World War I Nobel prize awarded jointly in 1912 to Victor Grignard and Paul Sabatier. In addition, the influence of the two mandarins then in power, Charles Prévost at the Sorbonne and Albert Kirrmann, a Dean in Strasbourg who would be called upon as vice-director at the École normale supérieure in Paris, saw to it that the only theory of organic reactions, admissible in the classroom and in the laboratory, was Prévost's. As Mary Jo Nye has shown, a wall was erected against penetration of the ideas of the British school of Ingold and Hughes. Mechanistic chemistry, as was being vigorously studied by the contemporary Anglo-American physical organic chemists, was 'persona non grata' in France. Publication by Bianca Tchoubar, in 1960, of "Les mécanismes réactionnels en chimie organique" opened a breach. The irony was for Dr. Tchoubar, a militant member of the Communist Party and a lady of fierce opinions, to have become a propagandist for the Anglo-American school of mechanistic studies. Truth for her overruled political propaganda. Her little book was revolutionary in the French context of the times. Together with the GECO (Groupe d'étude de chimie organique) summer conferences pioneered by Guy Ourisson after his return from Harvard, it ushered in the new ideas. This historical essay, based on an in-depth study of Tchoubar's book, will include a portrait of this remarkable woman scientist. It will delve at some length into the renewal of French science initiated by De Gaulle's government after his return to power in 1958. The tension in the French scientific establishment of the sixties reflected two opposed versions of nationalism, the one conservative, Malthusian, inner-directed, the other forward-looking, eager for the recovery of national status, seeing a strong French science as a means for asserting national identity and independence from the two world power blocs.

Magnetic field structure in single late-type giants: the effectively single giant V390 Aurigae  

NASA Astrophysics Data System (ADS)

Aims: We have studied the active giant V390 Aur using spectropolarimetry to obtain direct and simultaneous measurements of the magnetic field and the activity indicators to obtain a precise insight of its activity. Methods: We used the spectropolarimeter NARVAL at the Bernard Lyot Telescope (Observatoire du Pic du Midi, France) to obtain a series of Stokes I and Stokes V profiles. Using the least-squares deconvolution (LSD) technique we were able to detect the Zeeman signature of the magnetic field in each of our 13 observations and to measure its longitudinal component. Using the wide wavelength range of the spectra we were able to monitor the CaII K&H and IR triplet, as well as the H? lines, which are activity indicators. To reconstruct the magnetic field geometry of V390 Aur on the basis of modelling the Stokes V profiles, we applied the Zeeman Doppler imaging (ZDI) inversion method and present a map for the magnetic field. Based on the obtained spectra, we also refined the fundamental parameters of the star and the Li abundance using MARCS model atmospheres. Results: The ZDI revealed a structure in the radial magnetic field consisting of a polar magnetic spot of positive polarity and several negative spots at lower latitude. A high latitude belt is present on the azimuthal field map, indicative of a toroidal field close to the surface. Similar features are observed in some RS CVn and FK Com -type stars. It was found that the photometric period cannot fit the behaviour of the activity indicators formed in the chromosphere. Their behaviour suggests slower rotation compared to the photosphere, but our dataset is too short for us to be able to estimate their exact periods. All these results can be explained in terms of an ? - ? dynamo operation, taking into account the stellar structure and rotation properties of V390 Aur that we studied with up-to-date stellar models computed at solar metallicity with the code STAREVOL. The calculated Rossby number also points to a very efficient dynamo. Based on data obtained using the Bernard Lyot Telescope at Observatoire du Pic du Midi, CNRS and Université Paul Sabatier, France.

Search for surface magnetic fields in Mira stars. First detection in ? Cygni  

NASA Astrophysics Data System (ADS)

Context. So far, surface magnetic fields have never been detected on Mira stars. Only recently have the spectropolarimetric capabilities of measuring it via the Zeeman effect become available to us. Then, to complete the knowledge of the magnetic field and of its influence during the transition from asymptotic giant branch to planetary nebulae stages, we have undertaken a search for magnetic fields on the surface of Mira stars. Aims: Our main goal is to constrain - at this stage of stellar evolution - the surface magnetic field (presence and strength) and to define the magnetic field strength dependence along the radial distance to the star, above the photosphere and across the circumstellar envelope of cool and evolved stars. Methods: We used spectropolarimetric observations (Stokes V spectra probing circular polarization), collected with the Narval instrument at TBL, in order to detect - with the least squares deconvolution (LSD) method - a Zeeman signature in the visible part of the spectrum. Results: We present the first spectropolarimetric observations of the S-type Mira star ? Cyg, performed around its maximum light. We detected a polarimetric signal in the Stokes V spectra and established its Zeeman origin. We claim that it is likely to be related to a weak magnetic field present at the photospheric level and in the lower part of the stellar atmosphere. We estimated the strength of its longitudinal component to about 2-3 gauss. This result favors a 1/r law for the variation in the magnetic field strength across the circumstellar envelope of ? Cyg. This is the first detection of a weak magnetic field on the stellar surface of a Mira star, and we discuss its origin in the framework of shock waves periodically propagating throughout the atmosphere of these radially pulsating stars. Conclusions: At the date of our observations of ? Cyg, the shock wave reaches its maximum intensity, and it is likely that the shock amplifies a weak stellar magnetic field during its passage through the atmosphere. Without such an amplification by the shock, the magnetic field strength would have been too low to be detected. For the first time, we also report strong Stokes Q and U signatures (linear polarization) centered on the zero velocity (i.e., on the shock front position). They seem to indicate that the radial direction would be favored by the shock during its propagation throughout the atmosphere.

Spectral analysis of the solar wind turbulence in the vicinity of Venus  

NASA Astrophysics Data System (ADS)

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

Methane Post-Processor Development to Increase Oxygen Recovery beyond State-of-the-Art Carbon Dioxide Reduction Technology  

NASA Technical Reports Server (NTRS)

State-of-the-art life support carbon dioxide (CO2) reduction technology, based on the Sabatier reaction, is theoretically capable of 50% recovery of oxygen from metabolic CO2. This recovery is constrained by the limited availability of reactant hydrogen. Post-processing of the methane byproduct from the Sabatier reactor results in hydrogen recycle and a subsequent increase in oxygen recovery. For this purpose, a Methane Post-Processor Assembly containing three sub-systems has been developed and tested. The assembly includes a Methane Purification Assembly (MePA) to remove residual CO2 and water vapor from the Sabatier product stream, a Plasma Pyrolysis Assembly (PPA) to partially pyrolyze methane into hydrogen and acetylene, and an Acetylene Separation Assembly (ASepA) to purify the hydrogen product for recycle. The results of partially integrated testing of the sub-systems are reported.

Methane Post-Processor Development to Increase Oxygen Recovery beyond State-of-the-Art Carbon Dioxide Reduction Technology  

NASA Technical Reports Server (NTRS)

State-of-the-art life support carbon dioxide (CO2) reduction technology, based on the Sabatier reaction, is theoretically capable of 50% recovery of oxygen from metabolic CO2. This recovery is constrained by the limited availability of reactant hydrogen. Post-processing of the methane byproduct from the Sabatier reactor results in hydrogen recycle and a subsequent increase in oxygen recovery. For this purpose, a Methane Post-Processor Assembly containing three sub-systems has been developed and tested. The assembly includes a Methane Purification Assembly (MePA) to remove residual CO2 and water vapor from the Sabatier product stream, a Plasma Pyrolysis Assembly (PPA) to partially pyrolyze methane into hydrogen and acetylene, and an Acetylene Separation Assembly (ASepA) to purify the hydrogen product for recycle. The results of partially integrated testing of the sub-systems are reported

Trade Study of Five In-Situ Propellant Production Systems for a Mars Sample Return Mission  

NASA Technical Reports Server (NTRS)

One of the goals of NASA's HEDS enterprise is to establish a long-term human presence on Mars at a fraction of the cost of employing today's technology. The most direct method of reducing mission cost is to reduce the launch mass of the spacecraft. If the propellants for the return phase of the mission are produced on Mars, the total spacecraft mass could be reduced significantly. An interim goal is a Mars Sample Return (MSR) mission, which is proposed to demonstrate the feasibility of in-situ propellant production (ISPP). Five candidate ISPP systems for producing two fuels and oxygen from the Martian atmosphere are considered in this design trade-off study: 1) Zirconia cell with methanol synthesis, 2) Reverse water gas shift with water electrolysis and methanol synthesis, 3) Sabatier process for methane product ion with water electrolysis, 4) Sabatier process with water electrolysis and partial methane pyrolysis, and 5) Sabatier/RWGS combination with water electrolysis.

The central idea behind both methods is to augment each leaf of the decision tree with a subtree containing addi- tional information concerning each feature' s values in that leaf. This is done by computing two limits (lower and upper) for

Evaluation of heterogeneity statistics as reasonable proxies of the error of precipitation quantile estimation in the Minneapolis-St. Paul region  

NASA Astrophysics Data System (ADS)

Estimating precipitation frequency is important in engineering, agriculture, land use planning, and many other disciplines. The index flood method alleviates small sample size issues due to short record length by calculating normalized quantile estimates for averaged data from a “region” of gauges. For a perfectly homogeneous region this adds no error; heterogeneity statistics seek to quantify a real-world region’s deviation from this assumption. Hosking and Wallis (1997) introduced a Monte Carlo heterogeneity statistic called here H1 and used a simulation study to assess its utility while rejecting two similar statistics called here H2 and H3. A nearly linear relationship was found between H1 and the percentage root mean square error (RMSE) increase due to heterogeneity, establishing H1 as a “reasonable proxy” of quantile error. The H1-percent RMSE added relationship found in the simulation experiment was used to find equivalent RMSEs for heterogeneity thresholds against which all three H statistics were tested. In this study the “reasonable proxy” relationship is evaluated across a highly skewed daily precipitation dataset in Minnesota for H1,H2 and H3. Simulated regions used in quantile error estimation are generated using at-site L-moment ratios scaled toward the regional mean with a shrinkage multiplier. A linear relationship is found between Monte Carlo estimates of quantile RMSE and both H1 and H2 across all possible regionalizations of twelve gauges. H2’s relationship is less linear than H1’s as quantified by Pearson’s r. A synthetic study is also undertaken using the same sample sizes, regional L-moment averages, and between-site variations as the Hosking and Wallis (1997) simulation. The H2-percent RMSE added relationship is found to be nearly as linear as for H1, complementing the enumeration study’s findings. Because H2’s linear relationship with percent RMSE added has approximately one-fourth the slope of theH1-RMSE relationship, heterogeneity thresholds calculated with reference to H1 should not be applied to H2. H2 thresholds can be derived from the H2-percent RMSE added relationship in analogous fashion to the method used in Hosking and Wallis (1997) for H1. The resulting thresholds are one-fourth the magnitude of the H1 thresholds.
