The aim of this study was to clarify the role of the erythrocyte inclusions found during the hematological screening of loggerhead population of the Mediterranean Sea. We studied the erythrocyte inclusions in blood specimens collected from six juvenile and nine adult specimens of the loggerhead turtle, Caretta caretta, from the Adriatic and Tyrrhenian Seas. Our study indicates that the percentage of mature erythrocytes containing inclusions ranged from 3 to 82%. Each erythrocyte contained only one round inclusion body. Inclusion bodies stained with May Grünwald-Giemsa show that their cytochemical and ultrastructure characteristics are identical to those of human Heinz bodies. Because Heinz bodies originate from the precipitation of unstable hemoglobin (Hb) and cause globular osmotic resistance to increase, we analyzed loggerhead Hb using electrophoresis and high-performance liquid chromatography to detect and quantitate Hb fractions. We also tested the resistance of Hb to alkaline pH, heat, isopropanol denaturation, and globular osmosis. Our hemogram results excluded the occurrence of any infection, which could be associated with an inclusion body, in all the specimens. Negative Feulgen staining indicated that the inclusion bodies are not derived from DNA fragmentation. We hypothesize that amino acid substitutions could explain why loggerhead Hb precipitates under normal physiologic conditions, forming Heinz bodies. The identification of inclusion bodies in loggerhead erythrocytes allow us to better understand the haematological characteristics and the physiology of these ancient reptiles, thus aiding efforts to conserve such an endangered species.

Throughout their academic careers Carl Rogers and Heinz Kohut developed two contrasting definitions of empathy that influenced the ways in which both men sought to help their clients cope with emotional suffering. These two different understandings of empathy are contrasted to each other and finally compared with the understanding of empathy demonstrated in the teachings and actions of Jesus. It is hoped that through studying these ancient religious narratives we might be able to recover a deeper meaning of empathy.

Non-contrast-enhanced computed tomography (CT) imaging of the heart enables noninvasive quantification of coronary artery calcification (CAC), a surrogate marker of the atherosclerotic burden in the coronary artery tree. Multiple studies have underlined the ability of CAC score for individual risk stratification and, accordingly, the American Heart Association recommended cardiac CT for risk assessment in individuals with an intermediate risk of cardiovascular events as measured by Framingham Risk Score. However, limitations in transcribing risk stratification algorithms based on American cohort studies into European populations have been acknowledged in the past. Moreover, data on implications for reclassification into higher- or lower-risk groups based on CAC scores were lacking. The Heinz Nixdorf Recall (HNR) study is a population-based cohort study that investigated the ability of CAC scoring in risk prediction for major cardiovascular events above and beyond traditional cardiovascular risk factors. According to Heinz Nixdorf Recall findings, CAC can be used for reclassification, especially in those in the intermediate-risk group, to advise on lifestyle changes for the reclassified low-risk category, or to implement intensive treatments for the reclassified high-risk individuals. This article discusses the present findings of the Heinz Nixdorf Recall Study with respect to the current literature, risk stratification algorithms, and current European guidelines for risk prediction.

Large-scale influences on the pre-genesis of tropical cyclone Karl (2010)

NASA Astrophysics Data System (ADS)

Griffin, Kyle S.

The genesis of Tropical Cyclone (TC) Karl (2010) in September 2010 provided a unique opportunity to examine the continuing problem of understanding tropical cyclogenesis. The precursor disturbance to Karl originated from a cluster of showers east of the Windward Islands and was well sampled by ongoing field campaigns, particularly the PRE-Depression Investigation of Cloud-systems in the Tropics (PREDICT), as the targeted disturbance progressed westward. While traditional genesis theories focusing on moisture and mass fields (e.g. top-down showerhead method) can explain the initial spin-up of the disturbance several days prior to its official genesis, additional perspectives are examined in concert with more traditional methods in order to provide a more complete analysis of the synoptic-scale patterns that influenced the pre-Karl disturbance. A surge of westerly winds from northern South America aids the initial spin-up of the pre-Karl disturbance on 8-9 September, leading to the formation of a nearly closed earth-relative circulation. It can be shown that these anomalous westerly winds are tied to the convectively active phase of a convectively coupled Kelvin wave (CCKW). The observed formation of the nearly closed circulation on 10 September is well timed with the passage of this convectively active phase, a relationship that has been shown to hold true in cases of CCKW-TC interactions around the globe. Physically, the CCKW increases deep convection and aids in the generation of low-level relative vorticity on the cyclonic shear side of the low-level westerly wind anomalies, both of which serve to help organize the pre-Karl disturbance. Finally, the passage of the CCKW coincides with an equatorward surge of cold air and southerly winds in the lee of the Andes, triggered by a passing mid-latitude disturbance on 31 August. As the surge passes the equator on 7 September, little temperature perturbation remains with the surge, but terrain-channeled low-level flow

Airborne radar data collected within Hurricane Karl (2010) provide a high-resolution glimpse of variations in the vertical precipitation structure around complex terrain in eastern Mexico. Widespread precipitation north of Karl’s track traced the strong gradient of terrain, suggesting orographic enhancement. Although the airborne radar did not sample the period of peak precipitation, time series of surface rainfall at three locations near the inner core show greater precipitation where flow was oriented to rise over the terrain. In regions of upslope flow, radar observations reveal reflectivity enhancement within 1–2 km of the surface. The shallow nature of the enhancement points tomore » orographically generated cloud water accreted by falling drops as a mechanism consistent with prior studies, while the heterogeneous nature of the enhancement suggests shallow convection was playing a role. In contrast, regions of downslope flow were characterized by uniform reflectivity above the ground and fallstreaks originating above the melting level. Unlike most previously studied tropical cyclones passing over topography, Karl made landfall on a mountainous continent, not an island. As Karl weakened and decayed over land, the vertical structure of the radar echo deteriorated north of the storm center, and infrared satellite imagery revealed a strong reduction in the upper-level cloud coverage; however, a small region of intense convection appeared and produced locally heavy rainfall as Karl was close to dissipation. In conclusion, these results indicate that orographic modification processes in a landfalling tropical cyclone are not static, and surface precipitation is highly sensitive to the changes.« less

Large-Scale Influences on the Genesis of Tropical Cyclone Karl (2010)

The events leading up to the genesis of Tropical Cyclone (TC) Karl (2010) provides a unique opportunity to examine the continuing problem of understanding tropical cyclogenesis. The PRE-Depression Investigation of Cloud-systems in the Tropics (PREDICT) field campaign allowed for detailed investigation of the tropical disturbance that served as the precursor to TC Karl as it progressed westward through the Caribbean Sea. The purpose of this presentation is to examine the evolution of the pre-Karl disturbance using both common synoptic-scale analyses as well as statistically-based equatorial wave analyses, focusing on where these analyses complement and enhance each other. One of the major factors in the initial spin-up of the pre-Karl tropical disturbance is a surge of southerly and westerly winds from northern South America on 8-10 September 2010. As the surge entered the Caribbean on 9 September, it aided in the formation of a nearly closed earth-relative cyclonic circulation near the southern Leeward Islands. This circulation weakened late on 10 September and remained weak through 13 September before increased organization led to TC genesis on 14 September. This southerly wind surge can be traced to a well-defined surge of anomalously cold air and enhanced southerly winds originating in the lee of the Argentinian Andes over a week prior. While the temperature anomalies wash out prior to reaching the equator, anomalous low-level winds progress into Colombia and Venezuela, where topography aids in turning the southerly winds eastward. An investigation of the pre-Karl environment utilizing wavenumber-frequency filtering techniques also suggests that the initial spin-up of pre-Karl can be associated with the active phase of a convectively coupled Kelvin wave (CCKW). The observed formation of the nearly closed cyclonic circulation on 10 September is well timed with the passage of anomalous westerly winds along and behind the convectively active phase of a CCKW.

David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

The Potassium-Argon Laser Experiment (KARLE): In Situ Geochronology for Planetary Robotic Missions

2014-01-01

Isotopic dating is an essential tool to establish an absolute chronology for geological events, including crystallization history, magmatic evolution, and alteration events. The capability for in situ geochronology will open up the ability for geochronology to be accomplished as part of lander or rover complement, on multiple samples rather than just those returned. An in situ geochronology package can also complement sample return missions by identifying the most interesting rocks to cache or return to Earth. The K-Ar Laser Experiment (KArLE) brings together a novel combination of several flight-proven components to provide precise measurements of potassium (K) and argon (Ar) that will enable accurate isochron dating of planetary rocks. KArLE will ablate a rock sample, measure the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measure the liberated Ar using mass spectrometry (MS), and relate the two by measuring the volume of the ablated pit by optical imaging. Our work indicates that the KArLE instrument is capable of determining the age of planetary samples with sufficient accuracy to address a wide range of geochronology problems in planetary science. Additional benefits derive from the fact that each KArLE component achieves analyses useful for most planetary surface missions.

Absolute dating of planetary samples is an essential tool to establish the chronology of geological events, including crystallization history, magmatic evolution, and alteration. Thus far, radiometric geochronology of planetary samples has only been accomplishable in terrestrial laboratories on samples from dedicated sample return missions and meteorites. In situ instruments to measure rock ages have been proposed, but none have yet reached TRL 6, because isotopic measurements with sufficient resolution are challenging. We have begun work under the NASA Planetary Instrument Definition and Development Program (PIDDP) to develop the Potassium (K) - Argon Laser Experiment (KArLE), a novel combination of several flight-proven components that will enable accurate KAr isochron dating of planetary rocks. KArLE will ablate a rock sample, measure the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measure the liberated Ar using quadrupole mass spectrometry (QMS), and relate the two by measuring the volume of the abated pit using a optical methods such as a vertical scanning interferometer (VSI). Our preliminary work indicates that the KArLE instrument will be capable of determining the age of several kinds of planetary samples to 100 Myr, sufficient to address a wide range of geochronology problems in planetary science. Additional benefits derive from the fact that each KArLE component achieves analyses common to most planetary surface missions.

Characterizing the Precipitation Processes in Hurricane Karl (2010) Through Analysis of Airborne Doppler Radar Data and Numerical Simulations

NASA Astrophysics Data System (ADS)

DeHart, J.; Houze, R.

2016-12-01

Airborne radar data and numerical simulations are employed to investigate the structure of Hurricane Karl (2010). Karl peaked in intensity as a major hurricane in the Gulf of Mexico before making landfall on the mountainous coast of Veracruz, Mexico. Multiple aircraft extensively sampled Karl during the NASA GRIP campaign, including NASA's DC-8 aircraft instrumented with the Advanced Precipitation Radar 2 (APR-2), which is a high-resolution, dual-frequency Doppler radar. Data from APR-2 provide a unique opportunity to characterize the precipitation structure of Karl as it underwent orographic modification. As Karl made landfall on 17 September 2010, the vertical structure of the precipitation echo varied spatially around the Mexican terrain. The precipitation variation was linked to several factors: landfall, orientation of flow relative to the topographic features, and differing characteristics inherent to the eyewall and rainbands. Despite the differences in the reflectivity intensity across the storm, we show that low-level reflectivity enhancement occurred only where upslope flow was favorable. The radar data indicate that the processes initially contributing to the reflectivity enhancement were warm-cloud processes, either through collection of orographically-generated cloud water or shallow convection. But as Karl weakened, the low-level enhancement processes were overshadowed by deep convection that developed along the terrain. Analysis of the radar data is complemented by a series of numerical simulations, which reasonably reproduce the track, intensity and structure of Karl. The simulated thermodynamic and kinematic patterns provide a holistic view of Karl's evolution during landfall. We use terrain modification experiments to examine the sensitivity of the orographic enhancement processes to the three-dimensional terrain and land surface characteristics. Consistent with the radar analysis, warm-cloud enhancement processes are visible in the spatial

The Potassium-Argon Laser Experiment (KarLE): In Situ Geochronology for Mars and Beyond

The search for life in the solar system depends upon discovering the right moments in planetary evolution: when habitable environments existed, when they declined, and when geologic processes operated to preserve traces of life after death. However, an incomplete knowledge of absolute Martian geochronology limits our ability to understand the timing of Martian evolutionary milestones, major climate changes, and stratigraphic epochs [1, 2]. Absolute dating relates these habitability markers to planetarywide geologic, atmospheric, and climate history places, and ties their occurrence to the history of the solar system, especially the Earth-Moon system and the timescale of evolution of life on Earth. KArLE is being developed to anchor the relative timeline of geological events to an absolute chronology that puts Mars into a wider solar system context. KArLE makes its measurements on rock samples that can be obtained by landers or rovers and inserted into a small, mechanically simple chamber. KArLE interrogates the samples using laser-induced breakdown spectrocopy (LIBS), mass spectrometry, and optical imaging. The KArLE experiment is flexible enough to accommodate any partner providing these instrument components, a creative approach that extends the ability of mission payloads to accomplish an additional highly-desirable science measurement for low cost and risk and minimal extra hardware.

Associated Universities, Inc., (AUI) and the National Radio Astronomy Observatory (NRAO) have awarded the 2007 Karl G. Jansky Lectureship to Professor Karl M. Menten of the Max-Planck-Institute for Radioastronomy in Bonn, Germany. The Jansky Lectureship is an honor established by the trustees of AUI to recognize outstanding contributions to the advancement of astronomy. Karl M. Menten Professor Karl M. Menten CREDIT: NRAO/AUI Click on image for high-resolution file (433 KB) Professor Menten is an extraordinarily productive scientist whose research has improved our fundamental understanding in a number of areas of astronomy. He has studied the chemistry of molecular clouds from which new stars are formed, the process of star formation in our own Milky Way Galaxy and in the early Universe, and the outer atmospheres of stars nearing the end of their "normal" lives. In 1991, Menten used NRAO's 140-foot Telescope at Green Bank, West Virginia, to discover strong radio emission from methanol masers in star-forming regions. These masers amplify, or strengthen, radio emission the same way a laser amplifies visible-light emission. Menten developed the observation of these methanol masers into a powerful tool for studying the formation of stars much more massive than our Sun, because the strong maser emission points astronomers to the stellar birthplaces. In addition, Menten pioneered the use of ultra-high-resolution observations with NRAO's Very Long Baseline Array to observe masers to make precision determinations of the structure, size and dynamics of the Milky Way. Menten received his doctoral degree in 1987 from the University of Bonn, Germany. He then joined the Harvard-Smithsonian Center for Astrophysics, working there until 1996, when he became the Director for Millimeter and Submillimeter Astronomy at the Max-Planck-Institute for Radioastronomy. In addition to that position, he also has been a Professor for Experimental Astrophysics at the University of Bonn since

If extinct and/or extant life is discovered on Mars, knowledge of the chronology of the biosphere will be of paramount importance. KArLE will provide absolute ages of Mars 2020 rocks, which will allow us to understand them in the context of Mars' geologic history, connect them to other landing sites, and compare Martian epochs of habitability with the Earth's history and evolution of life. KArLE significantly enhances the ability of Mars 2020 to meet its science objectives by performing in situ age dating on key lithologies, enabling targeted searches for ancient biosignatures and increasing the chances of identifying evidence for Martian microbial life. The KArLE investigation makes its measurements on a core sample obtained with the rover drill, inserted into a small, mechanically simple chamber, followed by interrogation by laser-induced breakdown spectroscopy (LIBS), mass spectrometry, and optical imaging. The KArLE experiment is flexible enough to accommodate any partner providing these instrument components, a creative approach that extends the ability of the Mars 2020 payload to accomplish an additional highly-desirable science measurement for low cost and risk and minimal extra hardware.

Absolute dating of planetary samples is an essential tool to establish the chronology of geological events, including crystallization history, magmatic evolution, and alteration. We are addressing this challenge by developing the Potassium (K) -- Argon Laser Experiment (KArLE), building on previous work to develop a K-Ar in situ instrument. KArLE ablates a rock sample, determines the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measures the liberated Ar using quadrupole mass spectrometry (QMS), and relates the two by the volume of the ablated pit using laser confocal microscopy (LCM). Our goal is for the KArLE instrument to be capable of determining the age of several kinds of planetary samples to address a wide range of geochronolgy problems in planetary science.

Heinz Werner: His Life, Ideas, and Contributions to Developmental Psychology in the First Half of the 20th Century.

Ostler, Teresa

2016-01-01

The author provides an overview of Heinz Werner's life and contributions to the field of developmental psychology during the first half of the 20th century. She focuses on his early work in Vienna and Munich as well as his tenure at the Psychological Institute in Hamburg, up through the time when he became a named Professor in Psychology at Clark University. Recognized as one of the founders of developmental psychology, Heinz Werner worked in the areas of perceptual development, comparative psychology, and symbol formation. Versatile in rigorous experimental methodologies, and in observational and phenomenological methodologies, Werner's approach to development stood in contrast to other approaches of development, both past and current. For Werner, development was a heuristic, a way of looking at processes in a variety of domains, including ontogeny, phylogeny, microgenesis, biology, developmental psychopathology, neuropsychology, and comparative psychology. Werner viewed development as proceeding from a state of relative globality and lack of differentiation to a state of increasing differentiation, articulation, and hierarchical integration, but he also stressed that individuals can function at different developmental levels under different times and conditions. Werner's holistic, organismic, comparative, and contextual approach to development transcended interdisciplinary boundaries, allowing him to study the interrelatedness between thought, language, feeling, perception, and culture.

From an analysis of the original correspondence, it has been possible to establish that Karl Marx's incapacitating skin disease was hidradenitis suppurativa, not 'boils' as was universally assumed at the time and since; the psychological effect of this illness on the man and his work appears to have been considerable.

How deeply honoured I am to have the opportunity to express my thoughts at this delightful celebration of David's achievements, so far, in his remarkable career. I have been asked to center my remarks on David's contributions to the mentoring and professional development of scientists early in their careers. This is a topic that I am more than happy to reflect on, because it gives me the opportunity to recall the exciting period I spent as one of David's postgraduate students at Imperial College in the early 1980s. It also gives me the chance to publicly express my gratitude to David for the opportunities he created for me at that time, as well as for the interest and care he has shown in my career and well-being ever since, as we have met up and exchanged news and ideas around the world: in New Mexico and Colorado, in Cancun, Paris and Trieste, at numerous March Meetings of the American Physical Society and, of course in London, Oxford, and my home town, Champaign-Urbana, location of the University of Illinois. I have been a member of David's circle for 25 years now, and I would like to tell you a little about how this came to be. Not because of what this says about me, but, rather, because of what it tells you about David and the rich generosity of his spirit and effort when it comes to supporting the underdog. I was indeed one such underdog—and that's putting it charitably—when I first met David in September of 1982, not long before the academic year was to begin. I had heard about the exciting circle of physical and mathematical ideas swirling around the spin glass question during the previous year, which I had spent at the University of California's Los Angeles campus, through an opportunity kindly arranged, as it happens, by Sam Edwards. But I was eager to return to the UK for postgraduate studies and to work on spin glasses, so I simply showed up at David's Imperial College office, unannounced (if I remember correctly). And with his characteristic

A Way Forward Beyond Karl Popper's and Donald T. Campbell's Dead-End Evolutionary Epistemologies.

PubMed

Wettersten, John

2016-01-01

Theories of natural thought processes have traditionally served as foundations for philosophies of science. The source of all knowledge is passively received observations; these are combined to produce certain knowledge. After David Hume showed that this was not possible, deductivist alternatives, that is, theories that find a source of knowledge in ideas not derived from observations, from Immanuel Kant to William Whewell in the mid-1 9th century, were introduced. In response, traditional associationist and inductivist views were refurbished; a deductivist alternative was developed by the W6rzburg School. Much later Karl Popper in philosophy and Donald T. Campbell in psychology integrated this view with evolutionary theory. Campbell wanted thereby to find a justificationist view, which would reduce philosophy of science to cognitive psychology; Popper rejected both justificationism and the reduction of philosophy of science to psychology. Campbell thought all rational processes were innate psychological processes; Popper thought psychological processes were used to develop various rational processes. Campbell could not show that all rational thought was reducible to innate psychological processes, nor how some justification of scientific theories was possible. Popper could not show how evolutionary theory contributed to our knowledge of psychological thought processes. Both failed to observe that cognitive processes are social; people have learned how to think by learning how to interact in social groups seeking understanding. When innate thought processes are studied as social characteristics, evolutionary theory can contribute to both cognitive psychology and the theory of rationality, as both Popper and Campbell wanted it to do.

Certified reference materials (CRMs) of water content are widely used in the calibration and validation of Karl Fischer coulometry and volumetry. In this study, the water content of the water saturated 1-octanol (WSO) CRM was certified by Karl Fischer coulometry, volumetry and quantitative nuclear magnetic resonance (Q NMR). The water content recovery by coulometry was 99.76% with a diaphragm-less electrode and Coulomat AG anolyte. The relative bias between the coulometry and volumetry results was 0.06%. In Q NMR, the water content of WSO is traceable to the International System (SI) of units through the purity of internal standard. The relative bias of water content in WSO between Q NMR and volumetry was 0.50%. The consistency of results for these three independent methods improves the accuracy of the certification of the RM. The certified water content of the WSO CRM was 4.76% with an expanded uncertainty of 0.09%. Copyright © 2012 Elsevier Ltd. All rights reserved.

Development of the Potassium-Argon Laser Experiment (KArLE) Instrument for In Situ Geochronology

Absolute dating of planetary samples is an essential tool to establish the chronology of geological events, including crystallization history, magmatic evolution, and alteration. Traditionally, geochronology has only been accomplishable on samples from dedicated sample return missions or meteorites. The capability for in situ geochronology is highly desired, because it will allow one-way planetary missions to perform dating of large numbers of samples. The success of an in situ geochronology package will not only yield data on absolute ages, but can also complement sample return missions by identifying the most interesting rocks to cache and/or return to Earth. In situ dating instruments have been proposed, but none have yet reached TRL 6 because the required high-resolution isotopic measurements are very challenging. Our team is now addressing this challenge by developing the Potassium (K) - Argon Laser Experiment (KArLE) under the NASA Planetary Instrument Definition and Development Program (PIDDP), building on previous work to develop a K-Ar in situ instrument [1]. KArLE uses a combination of several flight-proven components that enable accurate K-Ar isochron dating of planetary rocks. KArLE will ablate a rock sample, determine the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measure the liberated Ar using quadrupole mass spectrometry (QMS), and relate the two by the volume of the ablated pit using an optical method such as a vertical scanning interferometer (VSI). Our preliminary work indicates that the KArLE instrument will be capable of determining the age of several kinds of planetary samples to +/-100 Myr, sufficient to address a wide range of geochronology problems in planetary science.

1993-01-01

During the four month period, from December 1988 to March 1989, there was an outbreak of Heinz body positive hemolytic anemia in 34 patients undergoing hemodialysis in a 500-bed hospital, Seoul, Korea. The episodes of hemolysis were not reduced by changing the charcoal column and reverse osmosis system, or by adding ascorbic acid to the dialysate. The concentrations of nitrate, copper, aluminum and zinc in the treated water were all within the standards for hemodialysis. The chloramine concentration of the treated water was over 0.6 mg/L, markedly exceeding the allowable level of 0.1 mg/L. This high level of chloramine was proved to be due to the contamination of the water source by raw sewage. After we changed the source of water supply to another, no more episodes of hemolytic anemia occurred. It is concluded that chloramine is one of the major contaminants causing dialysis-induced hemolytic anemia and regular determinations are necessary, especially during winter and dry seasons.

To examine short-term and midterm outcomes after the David and Bentall procedures in patients with an acute type A aortic dissection. Between 2001 and 2017, patients (n = 135) with acute type A aortic dissection underwent an aortic root replacement with either the David (n = 40) or Bentall (n = 95) procedure. Perioperative outcome, reoperation rate, aortic valve function, and long-term survival were evaluated. The median age of the entire cohort was 56 years. Rates of malperfusion (21%), shock (16%), history of renal failure (4%), and extent of surgery were similar between David and Bentall groups. However, the David group was significantly younger (45 versus 61 years) with less hypertension (45% versus 66%), coronary artery disease (0% versus 17%), valvulopathy (5% versus 19%), and prior cardiac surgery (5% versus 21%). Overall operative mortality was 9.6% (David 3% and Bentall 13%). Composite outcome comprising myocardial infarction, stroke, new-onset renal failure, and operative mortality was 18% in the entire cohort (David 5% and Bentall 23%). In the David group, the freedom of moderate aortic insufficiency was 95% at 10 years. The rate of reoperation for pathology of the proximal aorta or aortic valve was 0% and 2% for the David and Bentall groups, respectively. Ten-year Kaplan-Meier survival was 66% (95% confidence interval: 51% to 77%) for the entire cohort, with 98% (95% confidence interval: 84% to 99%) survival in the David group and 57% (95% confidence interval: 42% to 70%) survival in the Bentall group. Both the David and Bentall procedures are appropriate surgical approaches for aortic root replacement in select patients with an acute type A aortic dissection.

Understanding the Relationships Between Lightning, Cloud Microphysics, and Airborne Radar-derived Storm Structure During Hurricane Karl (2010)

This study explores relationships between lightning, cloud microphysics, and tropical cyclone (TC) storm structure in Hurricane Karl (16 September 2010) using data collected by the NASA DC-8 and Global Hawk (GH) aircraft during NASA's Genesis and Rapid Intensification Processes (GRIP) experiment. The research capitalizes on the unique opportunity provided by GRIP to synthesize multiple datasets from two aircraft and analyze the microphysical and kinematic properties of an electrified TC. Five coordinated flight legs through Karl by the DC-8 and GH are investigated, focusing on the inner-core region (within 50km of the storm center) where the lightning was concentrated and the aircraft were well coordinated. GRIP datasets are used to compare properties of electrified and nonelectrified inner-core regions that are related to the noninductive charging mechanism, which is widely accepted to explain the observed electric fields within thunderstorms. Three common characteristics of Karl's electrified regions are identified: 1) strong updrafts of 10-20ms21, 2) deep mixed-phase layers indicated by reflectivities.30 dBZ extending several kilometers above the freezing level, and 3) microphysical environments consisting of graupel, very small ice particles, and the inferred presence of supercooled water. These characteristics describe an environment favorable for in situ noninductive charging and, hence, TC electrification. The electrified regions in Karl's inner core are attributable to a microphysical environment that was conducive to electrification because of occasional, strong convective updrafts in the eyewall.

Sigmund Freud (1856-1939) and Karl Köller (1857-1944) and the discovery of local anesthesia.

2009-01-01

The understanding, occasionally recognized, that Sigmund Freud had the intuition to use cocaine as local anesthetic for surgical procedures, or even that he played any role in the discovery of local anesthesia is not true. The objective of Freud's studies were different, and based in irrefutable evidence, Karl Köller was the real inventor of local anesthesia. In face of those facts, proper knowledge of this historically important subject is due. This report refers to the long-known properties of cocaine. It also remembers personal data, and the professional and scientific activities of Sigmund Freud and Karl Köller. It presents Freud's researches on the pathophysiological effects of cocaine. It exposes the reasons for the harsh criticism of Freud's concepts. It describes the sudden, but conscious and justified, idea of Karl Köller to study scientifically the use of cocaine as a local anesthetic in animals and humans. It indicates how those pioneering studies, that culminated with the discovery of local anesthesia by Köller and two presentations in Vienna on the subject, were done. It also reports the first ophthalmologic surgery under local anesthesia. It shows the immediate dissemination throughout the world of the discovery that marked the beginning of regional blocks. It comments several documents corroborating the role of Köller in this discovery. And, finally, it mentions the numerous homages received by Köller in different areas of the world. COCLUSIONS: Regional block was introduced by Karl Köller in 1884, when he demonstrated the feasibility of performing painless ophthalmologic surgeries by using cocaine as a local anesthetic. Sigmund Freud studied cocaine extensively, but he did not have direct participation in this important discovery.

In 1889 August Müller (1864-1949) reported the correction of his own high myopia with a ground scleral contact lens that had been manufactured in Berlin two years earlier. This paper provides the first conclusive identification, based upon primary sources, of the manufacturer of these lenses. They were made by an optical engineer, Karl Otto Himmler (1841-1903), whose firm enjoyed, until the outbreak of World War II, an international reputation for the manufacture of microscopes and their accessories.

The Potassium-Argon Laser Experiment (KArLE): In Situ Geochronology for Planetary Robotic Missions

NASA Technical Reports Server (NTRS)

Cohen, Barbara

2016-01-01

The Potassium (K) - Argon (Ar) Laser Experiment (KArLE) will make in situ noble-gas geochronology measurements aboard planetary robotic landers and roverss. Laser-Induced Breakdown Spectroscopy (LIBS) is used to measure the K abun-dance in a sample and to release its noble gases; the evolved Ar is measured by mass spectrometry (MS); and rela-tive K content is related to absolute Ar abundance by sample mass, determined by optical measurement of the ablated volume. KArLE measures a whole-rock K-Ar age to 10% or better for rocks 2 Ga or older, sufficient to resolve the absolute age of many planetary samples. The LIBS-MS approach is attractive because the analytical components have been flight proven, do not require further technical development, and provide complementary measurements as well as in situ geochronology.

[Karl Marx and the Malthusian theory of population].

PubMed

Jaggi, S

1985-06-01

An analysis of the works of Karl Marx is presented in order to demonstrate the importance of the population factor. The author contends that population growth is a critical factor in Marx's theory of the progressive impoverishment of the working class. However, because of his reluctance to acknowledge the value of the Malthusian contribution, Marx focused his analysis of the labor force under capitalism on the demand for workers and neglected the supply side, which is determined by the growth of population. The author concludes that Marxist theory would have benefited from greater consideration of Malthusian theory.

Volume Measurements of Laser-generated Pits for in Situ Geochronology Using KArLE (Potassium-Argon Laser Experiment)

French, R. A.; Cohen, B. A.; Miller, J. S.

2014-01-01

KArLE (Potassium-­-Argon Laser Experiment) has been developed for in situ planetary geochronology using the K - Ar (potassium-­-argon) isotope system, where material ablated by LIBS (Laser-­-Induced Breakdown Spectroscopy) is used to calculate isotope abundances. We are determining the accuracy and precision of volume measurements of these pits using stereo and laser microscope data to better understand the ablation process for isotope abundance calculations. If a characteristic volume can be determined with sufficient accuracy and precision for specific rock types, KArLE will prove to be a useful instrument for future planetary rover missions.

Molecular and morphological characterisation of two species of the genus Ellipsomyxa Køie, 2003 (Ceratomyxidae) from the gall-bladder of Liza saliens (Risso) off Tunisian coasts of the Mediterranean.

During examination of some species of the family Mugilidae, two coelozoic myxozoans were observed in the gall-bladder of the leaping mullet, Liza saliens (Risso). Spore morphology allowed us to allocate them to the genus Ellipsomyxa Køie, 2003, one of which is described here as new. Ellipsomyxa kalthoumi n. sp. was observed forming globular pseudoplasmodia and free spores floating in the bile. Mature spores are ellipsoidal, measuring 13-21 × 10-15 (17.2 × 13.2) µm and possessing two equal spherical polar capsules, 5-6 (5.5) µm in diameter, opening subterminally in opposite directions, with nine polar filament coils. Morphological data and molecular analysis of the small subunit rDNA sequences helped identify this parasite as a new species of Elliposmyxa. The second species identified as E. mugilis (Sitjà-Bobadilla & Alvarez-Pellitero, 1993) has oval spores with rounded ends, measuring 10-11 × 7-9 (10.5 × 8.0) µm and possessing two polar subspherical capsules, 2.7-3.0 (2.8) µm in diameter, opening subterminally in opposite directions. Spore morphometry and molecular study of the small subunit (SSU) of the rRNA gene identified this species as E. mugilis described from the same host in the Western Mediterranean off Spain. Phylogenetic analysis revealed Elliposmyxa as a monophyletic clade and showed that E. mugilis, E. syngnathi Køie & Karlsbakk, 2009, E. adlardi Whipps & Font, 2012 and E. gobii Køie, 2003 group in a subclade containing the Tunisian isolate of E. mugilis whereas E. kalthoumi n. sp. appears in a second subclade together with four Australian species, E. maniliensis Heiniger & Adlard, 2014, E. apogoni Heiniger & Adlard, 2014, E. nigropunctatis Heiniger & Adlard, 2014 and E. arothroni Heiniger & Adlard, 2014.

Karl Popper's Quantum Ghost

NASA Astrophysics Data System (ADS)

Shields, William

2004-05-01

Karl Popper, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others - in this case Niels Bohr and Werner Heisenberg. Underlying Popper's criticism was his belief that, first, the "standard interpretation" of quantum mechanics, sometimes called the Copenhagen interpretation, abandoned scientific realism and second, the assertion that quantum theory was "complete" (an assertion rejected by Einstein among others) amounted to an unfalsifiable claim. Popper insisted that the most basic predictions of quantum mechanics should continue to be tested, with an eye towards falsification rather than mere adding of decimal places to confirmatory experiments. His persistent attacks on the Copenhagen interpretation were aimed not at the uncertainty principle itself and the formalism from which it was derived, but at the acceptance by physicists of an unclear epistemology and ontology that left critical questions unanswered. In 1999, physicists at the University of Maryland conducted a version of Popper's Experiment, re-igniting the debate over quantum predictions and the role of locality in physics.

Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E.

Boyer, Carol A; Gray, Bradford H

2016-08-01

David Mechanic has been a pioneering leader in the social and behavioral sciences of health, health services, and health and mental health policy for more than fifty years. One of David's most distinctive qualities has been his vision in identifying trends and defining new research areas and perspectives in health care policy. His early work on how methods of physician payment by capitation and fee-for-service in England and the United States affected physicians' responses to patients and patient care addressed present challenges and many ongoing studies of payment mechanisms. His papers on rationing of health care established a framework for examining alternative allocation mechanisms and just decision making. Influential papers dealt with risk selection, policy challenges in managed care, reducing racial disparities, trust relationships between patients, doctors, and the public and health institutions, and the predicaments of health reform. Focusing on the implementation of the Affordable Care Act, David explored its opportunities and challenges especially in providing comprehensive and effective behavioral health services. A hallmark of his work has been his redirecting our attention to the most severely ill and those in greatest need. Less visible is the leadership and institution building endeavors and the many honors David has received. Copyright © 2016 by Duke University Press.

Mild cognitive impairment (MCI) describes the intermediate state between normal cognitive aging and dementia. Adverse effects of air pollution (AP) on cognitive functions have been proposed, but investigations of simultaneous exposure to noise are scarce. We analyzed the cross-sectional associations of long-term exposure to AP and traffic noise with overall MCI and amnestic (aMCI) and nonamnestic (naMCI) MCI. At the second examination of the population-based Heinz Nixdorf Recall study, cognitive assessment was completed in 4,086 participants who were 50-80 years old. Of these, 592 participants were diagnosed as having MCI (aMCI, n = 309; naMCI, n = 283) according to previously published criteria using five neuropsychological subtests. We assessed long-term residential concentrations for size-fractioned particulate matter (PM) and nitrogen oxides with land use regression, and for traffic noise [weighted 24-hr (LDEN) and night-time (LNIGHT) means]. Logistic regression models adjusted for individual risk factors were calculated to estimate the association of environmental exposures with MCI in single- and two-exposure models. Most air pollutants and traffic noise were associated with overall MCI and aMCI. For example, an interquartile range increase in PM2.5 and a 10 A-weighted decibel [dB(A)] increase in LDEN were associated with overall MCI as follows [odds ratio (95% confidence interval)]: 1.16 (1.05, 1.27) and 1.40 (1.03, 1.91), respectively, and with aMCI as follows: 1.22 (1.08, 1.38) and 1.53 (1.05, 2.24), respectively. In two-exposure models, AP and noise associations were attenuated [e.g., for aMCI, PM2.5 1.13 (0.98, 1.30) and LDEN 1.46 (1.11, 1.92)]. Long-term exposures to air pollution and traffic noise were positively associated with MCI, mainly with the amnestic subtype.

Methods: At the second examination of the population-based Heinz Nixdorf Recall study, cognitive assessment was completed in 4,086 participants who were 50–80 years old. Of these, 592 participants were diagnosed as having MCI (aMCI, n = 309; naMCI, n = 283) according to previously published criteria using five neuropsychological subtests. We assessed long-term residential concentrations for size-fractioned particulate matter (PM) and nitrogen oxides with land use regression, and for traffic noise [weighted 24-hr (LDEN) and night-time (LNIGHT) means]. Logistic regression models adjusted for individual risk factors were calculated to estimate the association of environmental exposures with MCI in single- and two-exposure models. Results: Most air pollutants and traffic noise were associated with overall MCI and aMCI. For example, an interquartile range increase in PM2.5 and a 10 A-weighted decibel [dB(A)] increase in LDEN were associated with overall MCI as follows [odds ratio (95% confidence interval)]: 1.16 (1.05, 1.27) and 1.40 (1.03, 1.91), respectively, and with aMCI as follows: 1.22 (1.08, 1.38) and 1.53 (1.05, 2.24), respectively. In two-exposure models, AP and noise associations were attenuated [e.g., for aMCI, PM2.5 1.13 (0.98, 1.30) and LDEN 1.46 (1.11, 1.92)]. Conclusions: Long-term exposures to air pollution and traffic noise were positively associated with MCI, mainly with the amnestic subtype.

The study considers the origins of Karl Jaspers' phenomenology. What did phenomenology mean to Jaspers and what was his personal perspective? What metaphors did he associate with it? This paper describes his phenomenological method by using the metaphors of histology and the X-ray. This perspective enables a better understanding, not only of the origins and essence of his phenomenology but also of its value for Jaspers himself. In Jaspers' daily life, he would have been familiar with microscopes and X-ray machines.

This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery). The monitoring was carried out by a no-contact technique using an interferometric radar, whose effectiveness in measuring the resonant frequencies of structures and historic monuments has proved over the last years through numerous monitoring activities. Owing to the dynamic behavior of the measurement system (radar and tripod), an accelerometer has been installed on the radar head to filter out the movement component of the measuring instrument from the measurement of the David's displacement. Measurements were carried out in the presence and absence of visitors, to assess their influence on the dynamic behavior of the statue. A numerical model of the statue was employed to evaluate the experimental results.

This study examined the geologic data, mining history, and subsidence trends of the St. David region. Mine subsidence has occurred due to collapse of the abandoned mine workings. The known subsidence areas have been mapped and described. Results of the study include: (1) St. David has been undermined by both large shipping mines and smaller local mines; (2) sinkholes will continue to develop in this area in response to rock failure and roof collapse above the abandoned mine workings; (3) some primary factors that contribute to the sinkhole problems are the undermining and roof rock composition; (4) sinkholes will bemore » smaller in the future; (5) ten of the 63 sinkholes occurred close enough to structures to cause damage, and only six sinkholes caused damage; (6) ways to minimize potential damage to future homes from sinkhole subsidence are manageable; (7) threats to residents lie in the collapse of heavy walls, brick chimneys, breaks in gas, water, or electrical lines; and (8) location of future subsidence is not predictable.

While attending medical school at McGill, David Hubel developed an interest in the nervous system during the summers he spent at the Montreal Neurological Institute. After heading to the United States in 1954 for a Neurology year at Johns Hopkins, he was drafted by the army and was assigned to the Neuropsychiatry Division at the Walter Reed Hospital, where he began his career in research and did his first recordings from the visual cortex of sleeping and awake cats. In 1958, he moved to the lab of Stephen Kuffler at Johns Hopkins, where he began a long and fruitful collaboration with Torsten Wiesel. Born in Sweden, Torsten Wiesel began his scientific career at the Karolinska Institute, where he received his medical degree in 1954. After spending a year in Carl Gustaf Bernhard's laboratory doing basic neurophysiological research, he moved to the United States to be a postdoctoral fellow with Stephen Kuffler. It was at Johns Hopkins where he met David Hubel in 1958, and they began working together on exploring the receptive field properties of neurons in the visual cortex. Their collaboration continued until the late seventies. Hubel and Wiesel's work provided fundamental insight into information processing in the visual system and laid the foundation for the field of visual neuroscience. They have had many achievements, including--but not limited to--the discovery of orientation selectivity in visual cortex neurons and the characterization of the columnar organization of visual cortex through their discovery of orientation columns and ocular-dominance columns. Their work earned them the Nobel Prize for Physiology or Medicine in 1981, which they shared with Roger Sperry. Copyright © 2012 Elsevier Inc. All rights reserved.

Editors' Note Each year, the editorial board invites a distinguished member of the oceanographic community to contribute a prefatory chapter; this year, we were delighted when Karl Turekian, Sterling Professor of Geology and Geophysics at Yale, accepted our invitation. Over the course of a long and productive career, Dr. Turekian has pursued his interests in marine and atmospheric geochemistry by using natural radioactive and radiogenic isotopes to study Earth's evolution and the impacts of global change. He has also directed both the Center for the Study of Global Change at Yale and the Yale Institute for Biospheric Studies. In this interview, conducted by his former student Kirk Cochran, Dr. Turekian tells the story of his early career and discusses some of the major scientific challenges and opportunities faced along the way. His personal account of the rise of geochemistry is a charming story of how chance events and personalities impact scientific careers. His technical insight into the future of this field is illuminating, particularly for scientific outsiders who appreciate the central role of geochemistry in discerning and understanding patterns of global change.

Volume Measurements of Laser-generated Pits for In Situ Geochronology using KArLE (Potassium-Argon Laser Experiment)

NASA Technical Reports Server (NTRS)

French, R. A.; Cohen, B. A.; Miller, J. S.

2014-01-01

The Potassium-Argon Laser Experiment( KArLE), is composed of two main instruments: a spectrometer as part of the Laser-Induced Breakdown Spectroscopy (LIBS) method and a Mass Spectrometer (MS). The LIBS laser ablates a sample and creates a plasma cloud, generating a pit in the sample. The LIBS plasma is measured for K abundance in weight percent and the released gas is measured using the MS, which calculates Ar abundance in mols. To relate the K and Ar measurements, total mass of the ablated sample is needed but can be difficult to directly measure. Instead, density and volume are used to calculate mass, where density is calculated based on the elemental composition of the rock (from the emission spectrum) and volume is determined by pit morphology. This study aims to reduce the uncertainty for KArLE by analyzing pit volume relationships in several analog materials and comparing methods of pit volume measurements and their associated uncertainties.

Presents an obituary for David L. Rosenhan (1929-2012). A distinguished psychologist and professor emeritus at Stanford University, Rosenhan died February 6, 2012, at the age of 82, after a long illness. Born in Jersey City, New Jersey, on November 22, 1929, he received a bachelor's degree in mathematics (1951) from Yeshiva College and a master's degree in economics (1953) and a doctorate in psychology (1958) from Columbia University. A professor of law and of psychology at Stanford University from 1971 until his retirement in 1998, Rosenhan was a pioneer in applying psychological methods to the practice of law, including the examination of expert witnesses, jury selection, and jury deliberation. A former president of the American Psychology-Law Society and of the American Board of Forensic Psychology, Rosenhan was a fellow of the American Association for the Advancement of Science, of the American Psychological Association, and of the American Psychological Society. Before joining the Stanford Law School faculty, he was a member of the faculties of Swarthmore College, Princeton University, Haverford College, and the University of Pennsylvania. He also served as a research psychologist at the Educational Testing Service. As generations of Stanford students can attest, David Rosenhan was a spellbinding lecturer who managed to convey the sense that he was speaking to each individual, no matter how large the group. To his graduate students, he was consistently encouraging and optimistic, always ready to share a joke or story, and gently encouraging of their creativity and progressive independence as researchers. The lessons he cared most about offering, in the classroom as in his research, were about human dignity and the need to confront abuse of power and human frailties. © 2013 APA, all rights reserved.

Karl Heinrich Ulrichs: First Theorist of Erotic Age Orientation.

PubMed

Janssen, Diederik F

2017-01-01

The nomination of Karl Heinrich Ulrichs (1825-1895) as the first theorist of homosexuality may be placed in the oblique light of his eligibility for the nomination as the first theorist of erotic age orientation. In Ulrichs's pamphlets, "man-manly" homosexuality emerged as a particular age orientation, with a subsequent typological breakdown that, importantly, blended gender orientation and age orientation. Into the early 20th century, erotic age orientation remained bound up with the classification and emancipation of what here was demarcated as Urningsliebe. Ulrichs's pioneering and shifting comments on age eventually fed into his legal model of consenting adults in private. They also provide a starting point for the historical understanding of the trope of "grooming pedophile" as it, arguably, crossfaded with that of the "seducing homosexual" after the latter's depsychiatricization across the Western world.

Within the fields of medicine and sociology, the descriptor "profession" (along with its brethren: profession, professionalization, and professionalism) has had a rich etymological history, with terms taking on different meanings at different times-sometimes trespassing into shibboleth and jargon. This etymological journey has co-evolved with the career of David Mechanic to whom this issue of the Journal of Health Politics, Policy and Law is devoted. We exploit a provocative metaphor applied to Mechanic's work on the challenges facing medicine as a profession as a playful exegesis on what we call "profession" to excavate an ensconced and encrusted domain of health jargon operating at the tensive interface of society and modern medical work.

The calibration of Karl Fischer instruments and reagents and the compensation for instrumental bias are essential to the accurate measurement of trace levels of water in organic and inorganic chemicals. A stable, nonhygroscopic standard, Water Saturated Octanol, which is compatible with the Karl Fischer reagents, has been prepared. This material, Standard Reference Material (SRM) 2890, is homogeneous and is certified to contain 39.24 +/- 0.85 mg water/mL (expanded uncertainty) of solution (47.3 +/- 1.0 mg water/g solution, expanded uncertainty) at 21.5 degrees C. The solubility of water in -octanol has been shown to be nearly constant between 10 degrees C and 30 degrees C (i.e., within 1% of the value at 21.5 degrees C). The results of an interlaboratory comparison exercise illustrate the utility of SRM 2890 in assessing the accuracy and bias of Karl Fischer instruments and measurements.

EDITORIAL: From reciprocal space to real space in surface science From reciprocal space to real space in surface science

Bartels, Ludwig; Ernst, Karl-Heinz

2012-09-01

This issue is dedicated to Karl-Heinz Rieder on the occasion of his 70th birthday. It contains contributions written by his former students and colleagues from all over the world. Experimental techniques based on free electrons, such as photoelectron spectroscopy, electron microscopy and low energy electron diffraction (LEED), were foundational to surface science. While the first revealed the band structures of materials, the second provided nanometer scale imagery and the latter elucidated the atomic scale periodicity of surfaces. All required an (ultra-)high vacuum, and LEED illustrated impressively that adsorbates, such as carbon monoxide, hydrogen or oxygen, can markedly and periodically restructure surfaces from their bulk termination, even at pressures ten orders of magnitude or more below atmospheric. Yet these techniques were not generally able to reveal atomic scale surface defects, nor could they faithfully show adsorption of light atoms such as hydrogen. Although a complete atom, helium can also be regarded as a wave with a de Broglie wavelength that allows the study of surface atomic periodicities at a delicateness and sensitivity exceeding that of electrons-based techniques. In combination, these and other techniques generated insight into the periodicity of surfaces and their vibrational properties, yet were limited to simple and periodic surface setups. All that changed with the advent of scanning tunneling microscopy (STM) roughly 30 years ago, allowing real space access to surface defects and individual adsorbates. Applied at low temperatures, not only can STM establish a height profile of surfaces, but can also perform spectroscopy and serve as an actuator capable of rearranging individual species at atomic scale resolution. The direct and intuitive manner in which STM provided access as a spectator and as an actor to the atomic scale was foundational to today's surface science and to the development of the concepts of nanoscience in general.

1995-01-01

The life of 18th century astronomer, craftsman, and partriot David Rittenhouse is detailed. As a craftsman, he distinguished himself as one of the foremost builders of clocks. He also built magnetic compasses and surveying instruments. The finest examples of his craftsmanship are considered two orreries, mechanical solar systems.

1993-01-01

The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan.

Descriptive psychopathology, phenomenology, and the legacy of Karl Jaspers

PubMed Central

Häfner, Heinz

2015-01-01

With his early publications (1910-1913), Karl Jaspers created a comprehensive methodological arsenal for psychiatry, thus laying the foundation for descriptive psychopathology. Following Edmund Husserl, the founder of philosophical phenomenology, Jaspers introduced phenomenology into psychopathology as “static understanding,” ie, the unprejudiced intuitive reproduction (Vergegenwärtigung) and description of conscious phenomena. In a longitudinal perspective, “genetic understanding” based on empathy reveals how mental phenomena arise from mental phenomena. Severance in understanding of, or alienation from, meaningful connections is seen as indicating illness or transition of a natural development into a somatic process. Jaspers opted for philosophy early. After three terms of law, he switched to studying medicine, came to psychopathology after very little training in psychiatry; to psychology without ever studying psychology; and to a chair in philosophy without ever studying philosophy. In the fourth and subsequent editions of his General Psychopathology, imbued by his existential philosophy, Jaspers partly abandoned the descriptive method. PMID:25987860

David Lasser was one of the founders of the American Interplanetary Society (later known as the American Rocket Society) and author of the first English-language book (in 1931) on the prospects of human spaceflight. Yet his involvement in the fledgling spaceflight movement was short-lived as he soon moved on to pursue a distinguished career in the cause of workers rights. In lieu of an oral history, the author corresponded with Mr. Lasser on a regular basis in the years before his death in 1996 to gather Mr. Lasser's views on human spaceflight activities as viewed from his unique perspective. This paper will document that correspondence with one of America's original spaceflight pioneers.

Aortic Root Biomechanics After Sleeve and David Sparing Techniques: A Finite Element Analysis.

2017-05-01

Aortic root aneurysm can be treated with valve-sparing procedures. The David and Yacoub techniques have shown excellent long-term results but are technically demanding. Recently, a new and simpler procedure, the Sleeve technique, was proposed with encouraging results. We aimed to quantify the biomechanics of the initially aneurysmal aortic root (AR) after the Sleeve procedure to assess whether it induces abnormal stresses, potentially undermining its durability. Two finite element (FE) models of the physiologic and aneurysmal AR were built, accounting for the anatomical asymmetry and the nonlinear and anisotropic mechanical properties of human AR tissues. On the aneurysmal model, the Sleeve and David techniques were simulated based on the corresponding published technical features. Aortic root biomechanics throughout 2 consecutive cardiac cycles were computed in each simulated configuration. Both sparing techniques restored physiologic-like kinematics of aortic valve (AV) leaflets but induced different leaflets stresses. The time course averaged over the leaflets' bellies was 35% higher in the David model than in the Sleeve model. Commissural stresses, which were equal to 153 and 318 kPa in the physiologic and aneurysmal models, respectively, became 369 and 208 kPa in the David and Sleeve models, respectively. No intrinsic structural problems were detected in the Sleeve model that might jeopardize the durability of the procedure. If corroborated by long-term clinical outcomes, the results obtained suggest that using this new technique could successfully simplify the surgical repair of AR aneurysms and reduce intraoperative complications.

Thirty years ago, technology companies began nestling their facilities close to academia, and the idea of the university research park was born. Soon after, the concept took off in the field of medicine, and today it's not hard to find such innovation hubs that house biomedical startups drawing on the brainpower of professors and students alike. In late September, the Tucson, Arizona-based Association of University Research Parks--which includes about 170 research parks--announced that David Baker would serve as president of the organization's board of directors for the next year and help guide its strategic goals for the next five years. Baker, who is also the executive director of the University Technology Park at the Illinois Institute of Technology in Chicago, spoke with Roxanne Khamsi about how the organization hopes to branch out and transform these workplaces.

Motion of David Glacier in East Antarctica Observed by COSMO-SkyMed Differential SAR Interferometry

NASA Astrophysics Data System (ADS)

Han, H.; Lee, H.

2011-12-01

David glacier, located in Victoria Land, East Antarctica (75°20'S, 161°15'E), is an outlet glacier of 13 km width near the grounding line and 50 km long from the source to the grounding line. David glacier flows into Ross Sea forming Drygalski Ice Tongue, 100 km long and 23 km wide. In this study, we extracted a surface displacement map of David by applying differential SAR interferometry (DInSAR) to one-day tandem pairs obtained from COSMO-SkyMed satellites on April 28-29 (descending orbit) and May 5-6 (ascending orbit), 2011, respectively. Terra ASTER global digital elevation model (GDEM) is used to remove the topographic effect from the COSMO-SkyMed interferograms. David glacier showed maximum displacement of 35 cm during April 28-29 and 20 cm during May 5-6 in the direction of radar line of sight. The glacier can be divided into several blocks by the disparities of displacement between the different sliding zone. Surface displacement map contains errors originated from orbit data, atmospheric conditions, DEM error. GDEM is generated from the ASTER optical images acquired from 2000 to 2008. It has the vertical accuracy of about 20 m at 95% confidence with the 30 m of horizontal posting. The accuracy of GDEM reduces when cloud cover is included in the ASTER image. Particularly in the snow and ice area, GDEM is inaccurate due to whiteout effect during stereo matching. The inaccuracy of GDEM could be a reason of the observed glacier motion in the opposite direction of gravity. This problem can be solved by using TanDEM-X DEM. Bistatic acquisition of SAR images from the constellation of TerraSAR-X and TanDEM-X will generate a global DEM with the vertical accuracy better than 2 m and the horizontal posting of 12 m. We plan to perform DInSAR of COSMO-SkyMed one-day tandem pairs again when the high-accuracy TanDEM-X DEM is available in the near future. As a conclusion, we could analyze the displacement of David glacier in East Antarctica. The glacier showed very fast

Comparison between amperometric and true potentiometric end-point detection in the determination of water by the Karl Fischer method.

PubMed

Cedergren, A

1974-06-01

A rapid and sensitive method using true potentiometric end-point detection has been developed and compared with the conventional amperometric method for Karl Fischer determination of water. The effect of the sulphur dioxide concentration on the shape of the titration curve is shown. By using kinetic data it was possible to calculate the course of titrations and make comparisons with those found experimentally. The results prove that the main reaction is the slow step, both in the amperometric and the potentiometric method. Results obtained in the standardization of the Karl Fischer reagent showed that the potentiometric method, including titration to a preselected potential, gave a standard deviation of 0.001(1) mg of water per ml, the amperometric method using extrapolation 0.002(4) mg of water per ml and the amperometric titration to a pre-selected diffusion current 0.004(7) mg of water per ml. Theories and results dealing with dilution effects are presented. The time of analysis was 1-1.5 min for the potentiometric and 4-5 min for the amperometric method using extrapolation.

Using optically scanned 3D data in the restoration of Michelangelo's David

Modern 3D scanning technologies allow to reconstruct 3D digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth of details. The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

2009-01-01

Even a century after its first publication in "Archives of Criminology" (in German: Archiv für Kriminologie), the doctoral thesis of Karl Jaspers (1883-1969), which was newly edited in 1996, continues to be of interest. Although the crimes described by Jaspers, which took place in a rural area, do no longer occur in this form just as the rural culture itself has disappeared, this paper nevertheless contains reflections that may also be relevant for the interpretation of modern potentials of conflict and violence and crimes rooted therein. The former homesickness has developed into novel phenomena of uprooting. In both cases, problems of maladjustment are a contributing factor to crime motivation. Thus despite all terminological and methodological change, Jaspers' thesis is an example for the continuing relevance of certain subjects in criminological discourse.

2016-05-01

Traffic noise affects a large number of people, particularly in urbanized areas. Noise causes stress and annoyance, but less is known about the relationship between noise and depression. We investigated the association of residential road traffic noise with depressive symptoms using 5-year follow-up data from a German population-based study. We analyzed data from 3,300 participants in the Heinz Nixdorf Recall study who were between 45 and 75 years old and were without depressive symptoms at baseline (2000-2003). Depressive symptoms were defined based on the Center for Epidemiologic Studies Depression scale (CES-D) 15-item questionnaire (total score ≥ 17) and antidepressant medication intake. Road traffic noise was modeled according to European Parliament/Council Directive 2002/49/EC. High noise exposure was defined as annual mean 24-hr noise levels > 55 A-weighted decibels [dB(A)]. Poisson regression with robust variance was used to estimate relative risks (RRs) a) adjusting for the potential confounders age, sex, socioeconomic status (SES), neighborhood-level SES, and traffic proximity; b) additionally adjusting for body mass index and smoking; and c) additionally adjusting for the potential confounders/intermediates comorbidities and insomnia. Overall, 35.7% of the participants were exposed to high residential road traffic noise levels. At follow-up (mean = 5.1 years after baseline), 302 participants were classified as having high depressive symptoms, corresponding to an adjusted RR of 1.29 (95% CI: 1.03, 1.62; Model 1) for exposure to > 55 versus ≤ 55 dB(A). Adjustment for potential confounders/intermediates did not substantially alter the results. Associations were stronger among those who reported insomnia at baseline (RR = 1.62; 95% CI: 1.10, 2.59 vs. RR = 1.21; 95% CI: 0.94, 1.57) and appeared to be limited to those with ≤ 13 years of education (RR = 1.43; 95% CI: 1.10, 1.85 vs. 0.92; 95% CI: 0.56, 1.53 for > 13 years).

Karl Pearson and eugenics: personal opinions and scientific rigor.

PubMed

Delzell, Darcie A P; Poliak, Cathy D

2013-09-01

The influence of personal opinions and biases on scientific conclusions is a threat to the advancement of knowledge. Expertise and experience does not render one immune to this temptation. In this work, one of the founding fathers of statistics, Karl Pearson, is used as an illustration of how even the most talented among us can produce misleading results when inferences are made without caution or reference to potential bias and other analysis limitations. A study performed by Pearson on British Jewish schoolchildren is examined in light of ethical and professional statistical practice. The methodology used and inferences made by Pearson and his coauthor are sometimes questionable and offer insight into how Pearson's support of eugenics and his own British nationalism could have potentially influenced his often careless and far-fetched inferences. A short background into Pearson's work and beliefs is provided, along with an in-depth examination of the authors' overall experimental design and statistical practices. In addition, portions of the study regarding intelligence and tuberculosis are discussed in more detail, along with historical reactions to their work.

There is strong evidence for an association of olfactory dysfunction and neurodegenerative diseases. Studies on the association of olfaction and cognition in the general population are rare. To evaluate gender- and age-specific associations of olfactory function and cognitive performance in a well characterized population-based study sample. At the third examination of the Heinz Nixdorf Recall study (n = 3,087), 2,640 participants (48% men; 68.2±7.2 years) underwent Sniffin' Sticks Screening Test measuring olfactory function on a scale of 0-12 points. Olfactory function was rated as anosmic, hyposmic, or normosmic (≤6, 7-10 or ≥11 points, respectively). All participants performed eight validated cognitive subtests. Age- (55-64 years, 65-74 years, 75-86 years) and gender-stratified multivariate analysis of covariance was used to evaluate group differences in cognitive performance. Women showed better olfactory function than men (p < 0.001). For middle-aged participants, olfactory groups differed in almost all cognitive subtests. The analyses revealed no gender effects, although associations were slightly greater for women than for men. Anosmics showed the worst cognitive performance and normosmics showed the best cognitive performance. In the young- and old-aged groups, a quantitative association was found for anosmics in all subtests and for normosmics and hyposmics in almost all subtests. This is the first study reporting on age-specific associations of olfactory function and cognitive performance in the general population. The association found in middle-aged participants (65-74 years) may serve as a marker to improve identification of persons at high risk for cognitive decline and dementia.

Karl Friedrich Zollner and the historical dimension of astronomical photometry

NASA Astrophysics Data System (ADS)

Sterken, C.; Staubermann, K. B.

This book results from presentations and discussions of a group of astronomers and historians during a one-day workshop held at Archenhold Observatory, Berlin-Treptow, on April 4, 1997. This meeting was the first forum in a series dedicated to historical aspects of observational astrophysics in the nineteenth and early twentieth century. The basic principle of these meetings is to reflect during one or more days on the work and personality of a single individual or of a group of persons, at the same time avoiding the really dominant figures that typify the age. By focusing on key people who epitomize a way of thinking and working that has formed many of the ideas by which we do astrophysical research today, we also attempt to evoke the scientific spirit of the era under consideration. In 1858, the German physicist Karl Friedrich Zoellner introduced a new type of astronomical photometer which became a bestseller in the second half of the nineteenth century and which led him to the first German professorship in astrophysics. His type of photometer allowed most accurate photometric measurements and was used at several observatories for almost half a century. This book outlines four major themes. The first part describes the observing instruments that were used by Zoellner and his contemporaries: photometers and spectrographs that complemented his original design, but also competed with his most versatile prototype photometer. The description also includes an account of technical aspects associated with the replication of such a photometer today. The second part analyses the astrophysical data that were obtained with Zoellner's tools, and extracts information hidden in the published data --- scientific information as well as diverse aspects related to the observer himself. These nineteenth-century data are now published for the first time on a modern magnitude scale and are directly accessible in tabular form, and are thus fully applicable to archeophotometric studies

Dinner at Orazio's--David Triggle the model of a mentor.

PubMed

Smith, Susan L

2015-11-15

What does it mean to be a mentor in science? Definitions of mentorship are freely spouted in publications and include concepts such as academic support, professional development, role modeling, interaction, impartment of knowledge, evaluation of work, demonstration of methodology, etc. Perhaps most of us would agree with the duties listed. But just what does it mean, for example, to offer academic support? How might one facilitate professional development for a mentee? While we may agree to the general obligations of a mentor the specifics of what these entail would prove more controversial. This article will illustrate how easy it is to pick out a bad mentor. There are certain elements of conduct that, if practiced, undoubtedly put you in the "bad mentor" category. However, it is very difficult to explain just what it means to be not only an adequate mentor but also a stellar one. It may be easy to list the roles and responsibilities of a mentor but just how should they be performed/carried out? David Triggle is the model of an extraordinary mentor. The conclusion of this paper will focus on some specific mentorship activities David Triggle carried out that illustrate some of the intangible aspects of excellence in mentorship.

Obituary: David L. Band (1957-2009)

Cominsky, Lynn

2011-12-01

David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community. Band showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, Band continued as a graduate student in Physics at Harvard University. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Jonathan Grindlay. His dissertation (1985) entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts," according to Grindlay who remained a personal friend and colleague of Band's. Following graduate school, Band held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. Band became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function." After the CGRO mission ended, Band moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned

The rediscovered estate of Karl Poggensee allows to reproduce chronologically his rocket tests of the period 1930-1934 almost completely for the first time. Thrilled by the movie ;The Woman in the Moon; for the idea of space travel, he started as a student of Hinderburg-Polytechnikum (IAO), Oldenburg, to build his first solid-fuel rocket, producing his own propellant charges. Being a coming electrical engineer his main goal was not set up new record heights, but to provide his rockets with automatic measuring instruments, camera and parachute release systems. The optimization of this sequence was his main focus.

David crighton, 1942-2000: a commentary on his career and his influence on aeroacoustic theory

NASA Astrophysics Data System (ADS)

Ffowcs Williams, John E.

David Crighton, a greatly admired figure in fluid mechanics, Head of the Department of Applied Mathematics and Theoretical Physics at Cambridge, and Master of Jesus College, Cambridge, died at the peak of his career. He had made important contributions to the theory of waves generated by unsteady flow. Crighton's work was always characterized by the application of rigorous mathematical approximations to fluid mechanical idealizations of practically relevant problems. At the time of his death, he was certainly the most influential British applied mathematical figure, and his former collaborators and students form a strong school that continues his special style of mathematical application. Rigorous analysis of well-posed aeroacoustical problems was transformed by David Crighton.

[The significance of Karl Landsteiner's works for syphilis research].

PubMed

Luger, A

1991-01-01

On January 7th 1905, more than five months before the detection of T. pallidum, Karl Landsteiner began his work on syphilis research together with notable members of the Viennese School of Medicine, namely Ernest Finger, Rudolf Müller, Viktor Mucha, Otto Pötzl and others. Extensive animal experiments led to the formulation of the Finger-Landsteiner Law and provided the basic facts for the Jadasson-Lewandowsky Law. Attempts of active or passive immunization were unsuccessful and, indeed, were still a failure in 1990 after implementation of the latest tools of modern research, including gene technology. Dark-field microscopy was introduced for the detection of T. pallidum by Landsteiner and Mucha. These authors noted that serum of syphilitic patients inhibited the movements of T. pallidum and, thus, observed the basic principle underlying the T. pallidum immobilization test (= TPI = Nelson-Mayer test). Finally, Landsteiner, Müller and Pötzl discovered that it was not an antibody specific to T. pallidum that reacted in the Wassermann reaction, but "autotoxic" substances, which they called reagines. During the 1970's and 1980's it was discovered that these reagines are autoantibodies directed against parts of the inner envelope of the mitochondria.

An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference.

Background: Traffic noise affects a large number of people, particularly in urbanized areas. Noise causes stress and annoyance, but less is known about the relationship between noise and depression. Objective: We investigated the association of residential road traffic noise with depressive symptoms using 5-year follow-up data from a German population-based study. Methods: We analyzed data from 3,300 participants in the Heinz Nixdorf Recall study who were between 45 and 75 years old and were without depressive symptoms at baseline (2000–2003). Depressive symptoms were defined based on the Center for Epidemiologic Studies Depression scale (CES-D) 15-item questionnaire (total score ≥ 17) and antidepressant medication intake. Road traffic noise was modeled according to European Parliament/Council Directive 2002/49/EC. High noise exposure was defined as annual mean 24-hr noise levels > 55 A-weighted decibels [dB(A)]. Poisson regression with robust variance was used to estimate relative risks (RRs) a) adjusting for the potential confounders age, sex, socioeconomic status (SES), neighborhood-level SES, and traffic proximity; b) additionally adjusting for body mass index and smoking; and c) additionally adjusting for the potential confounders/intermediates comorbidities and insomnia. Results: Overall, 35.7% of the participants were exposed to high residential road traffic noise levels. At follow-up (mean = 5.1 years after baseline), 302 participants were classified as having high depressive symptoms, corresponding to an adjusted RR of 1.29 (95% CI: 1.03, 1.62; Model 1) for exposure to > 55 versus ≤ 55 dB(A). Adjustment for potential confounders/intermediates did not substantially alter the results. Associations were stronger among those who reported insomnia at baseline (RR = 1.62; 95% CI: 1.10, 2.59 vs. RR = 1.21; 95% CI: 0.94, 1.57) and appeared to be limited to those with ≤ 13 years of education (RR = 1.43; 95% CI: 1.10, 1.85 vs. 0.92; 95% CI: 0.56, 1.53 for

Dullo, Wolf-Christian; Pfaffl, Fritz A.

2017-09-01

Karl Andrée began studying questions of sedimentology and oceanography in 1908 when working as an assistant at the University of Marburg and he remained faithful to these subjects until his death in 1959. The vast majority of his scientific contributions, however, were published during his time at the University of Königsberg (1915-1945). There he published his fundamental papers on marine geology, all of which adhered strictly to the principles of uniformitarianism, and helped improve our understanding of sedimentary processes and the stratigraphic record. His scientific work has enormous breadth. In the course of 55 years, he published 124 individual papers and books, some of which became classic textbooks. His versatility is particularly evident in his book "Geology of the Seafloor", which contains many pertinent observations and descriptions still relevant today, even if it has fallen out of fashion. This scientist and university teacher was the first to successfully present the huge field of marine geology in all its facet and to consider the deposition of marine sediments as a function of their geographical distribution.

Sir Peter Medawar: science, creativity and the popularization of Karl Popper

PubMed Central

Calver, Neil

2013-01-01

Sir Peter Medawar was respected by scientists and literati alike. It was perhaps not surprising, then, that he would choose to involve himself in the ‘two cultures’ debate of 1959 and beyond. The focus of his intervention was the philosophy of Sir Karl Popper. However, Medawar's Popper was not the guru of falsification familiar from philosophy textbooks. Medawar's distinctive interpretation of Popper treated him instead as the source of insights into the role of creativity and imagination in scientific inquiry. This paper traces the context for Medawar's adoption of Popperian philosophy, together with its application before the debate. It then examines, within the context of the debate itself, the way in which Medawar attempted to reconcile scientific inquiry with literary practice. Medawar became increasingly convinced that not only was induction epistemologically unsound, but it was also damaging to the public role of the scientist. His construction of Popperianism would, he envisaged, provide a worthy alternative for scientists’ self-image.

Are air pollution and traffic noise independently associated with atherosclerosis: the Heinz Nixdorf Recall Study.

Living close to high traffic has been linked to subclinical atherosclerosis, however it is not clear, whether fine particulate matter (PM) air pollution or noise, two important traffic-related exposures, are responsible for the association. We investigate the independent associations of long-term exposure to fine PM and road traffic noise with thoracic aortic calcification (TAC), a reliable measure of subclinical atherosclerosis. We used baseline data (2000-2003) from the German Heinz Nixdorf Recall Study, a population-based cohort of 4814 randomly selected participants. We assessed residential long-term exposure to PM with a chemistry transport model, and to road traffic noise using façade levels from noise models as weighted 24 h mean noise (Lden) and night-time noise (Lnight). Thoracic aortic calcification was quantified from non-contrast enhanced electron beam computed tomography. We used multiple linear regression to estimate associations of environmental exposures with ln(TAC+1), adjusting for each other, individual, and neighbourhood characteristics. In 4238 participants (mean age 60 years, 49.9% male), PM2.5 (aerodynamic diameter ≤2.5 µm) and Lnight are both associated with an increasing TAC-burden of 18.1% (95% CI: 6.6; 30.9%) per 2.4 µg/m(3) PM2.5 and 3.9% (95% CI 0.0; 8.0%) per 5dB(A) Lnight, respectively, in the full model and after mutual adjustment. We did not observe effect measure modification of the PM2.5 association by Lnight or vice versa. Long-term exposure to fine PM and night-time traffic noise are both independently associated with subclinical atherosclerosis and may both contribute to the association of traffic proximity with atherosclerosis.

The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

2014-07-01

For the simultaneous analysis of short- and long-term effects of air pollution in the Heinz Nixdorf Recall Cohort a sophisticated exposure modelling was performed. The dispersion and chemistry transport model EURAD (European Air Pollution Dispersion) was used for the estimation of hourly concentrations of a number of pollutants for a horizontal grid with a cell size of 1 km² covering the whole study area (three large adjacent cities in a highly urbanized region in Western Germany) for the years 2000-2003 and 2006-2008. For each 1 km² cell we estimated the mean concentration by calculating daily means from the hourly concentrations modelled by the EURAD process. The modelled concentrations showed an overall tendency to decrease from 2001 to 2008 whereas the trend in the single grid cells and study period was inhomogeneous. Participant-related exposure slightly increased from 2001 to 2003 followed by a decrease from 2006 to 2008. The exposure modelling enables a very flexible exposure assessment compared to conventional modelling approaches which either use central monitoring or temporally static spatial contrasts. The modelling allows the calculation of an average exposure concentration for any place and time within the study region and study period with a high spatial and temporal resolution. This is important for the assessment of short-, medium and long-term effects of air pollution on human health in epidemiological studies.

2007-11-01

To understand effects of human disturbance on alert response of Père David's deer, we carried out an experiment in the Dafeng Père David's Deer Reserve (32 degrees 59'-33 degrees 03'N, 120 degrees 47'-120 degrees 53'E), China. In the spring and summer, we observed alert responses (including stare, walking away, and flee) of deer and recorded the intensity of tourist disturbance in a small display pen using a laser-range finder to measure the alert distance of a free-ranging group in a large enclosure. We also recorded the pattern of head orientation when deer were resting in these two deer groups. After statistical analysis, we found that: 1) in small pen, the frequency of alert response was significantly different among different intensities of human disturbance; strong disturbance resulted in higher frequency of alert response; 2) stare distance in the free-ranging group in summer was significantly longer than that in spring, but the distance of walking away and the distance of flee showed no significant difference between the two seasons; and 3) in free-ranging group, there was no significant directional difference in head orientation, whereas in display group, there was a significant directional difference in head orientation. We suggest that: 1) under the captive situation, human disturbance may be one of the factors that affect alert response in Père David's deer; and 2) Père David's deer adopted different alert response to adapt to human disturbance under different circumstance. We recommended that relationships between alert response and human disturbance should be considered in ex situ conservation of this field extinct deer. Zoo Biol 26:461-470, 2007.

David J. Hofmann, a pioneer in stratospheric aerosol and ozone research, passed away in Boulder, Colo., on 11 August 2009. He was 72. Dave, a frequent contributor to AGU publications and meetings, was elected an AGU Fellow in 2006. His long and prolific scientific career was, as he would say, simple in concept: Make a long-term commitment to specific measurements, pay attention to the details, and focus on the important issues that the measurements raise. This is simple in concept yet challenging to maintain in a world of short-term contracts and budgets. That Dave sustained and led key measurement programs through 25 years at the University of Wyoming (UW), in Laramie, and 17 years with the U.S. National Oceanic and Atmospheric Administration's (NOAA) Climate Monitoring and Diagnostics Laboratory (CMDL, which became the Global Monitoring Division (GMD) of NOAA's Earth System Research Laboratory) in Boulder, speaks volumes about the scientific and societal benefits that have resulted from his work. Most of the measurement programs he initiated, and the instruments he helped develop for them, continue today as testament to the value of his focus and lasting influence.

An important area of applied mathematics is the Chemical reaction network theory. The behavior of real world problems can be modeled by using this theory. Due to applications in theoretical chemistry and biochemistry, it has attracted researchers since its foundation. It also attracts pure mathematicians because it involves interesting mathematical structures. In this report, we compute newly defined topological indices, namely, Arithmetic-Geometric index (AG1 index), SK index, SK1 index, and SK2 index of the dominating David derived networks [1, 2, 3, 4, 5].

Simple Modification of Karl-Fischer Titration Method for Determination of Water Content in Colored Samples

PubMed Central

Tavčar, Eva; Turk, Erika; Kreft, Samo

2012-01-01

The most commonly used technique for water content determination is Karl-Fischer titration with electrometric detection, requiring specialized equipment. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a titration endpoint, appropriate for moisture determination of colored samples. The reaction takes place in a sealed 4 ml cuvette. Detection is performed at 520 nm. Titration endpoint is determined from the graph of absorbance plotted against titration volume. The method has appropriate reproducibility (RSD = 4.3%), accuracy, and linearity (R 2 = 0.997). PMID:22567558

Effects of Low O2 Root Stress on Ethylene Biosynthesis in Tomato Plants (Lycopersicon esculentum Mill cv Heinz 1350) 1

PubMed Central

Wang, Tzann-Wei; Arteca, Richard N.

1992-01-01

Low O2 conditions were obtained by flowing N2 through the solution in which the tomato plants (Lycopersicon esculentum Mill cv Heinz 1350) were growing. Time course experiments revealed that low O2 treatments stimulated 1-aminocyclopropane-1-carboxylate (ACC) synthase production in the roots and leaves. After the initiation of low O2 conditions, ACC synthase activity and ACC content in the roots increased and reached a peak after 12 and 20 hours, respectively. The conversion of ACC to ethylene in the roots was inhibited by low levels of O2, and ACC was apparently transported to the leaves where it was converted to ethylene. ACC synthase activity in the leaves was also stimulated by low O2 treatment to the roots, reaching a peak after 24 hours. ACC synthase levels were enhanced by cobalt chloride and aminooxyacetic acid (AOA), although they inhibited ethylene production. Cobalt chloride enhanced ACC synthase only in combination with low O2 conditions in the roots. Under aeration, AOA stimulated ACC synthase activity in both the roots and leaves. However, in combination with low O2 conditions, AOA caused a stimulation in ACC synthase activity in the leaves and no effect in the roots. PMID:16668654

Vendian microfossils in metasedimentary cherts of the Scotia Group, Prins Karls Forland, Svalbard

NASA Technical Reports Server (NTRS)

Knoll, A. H.

1992-01-01

Sedimentary rocks of the Scotia Group, Prins Karls Forland, Svalbard, have been metamorphosed to lower greenschist facies. Yet Scotia chert nodules contain abundant organic-walled microfossils belonging to at least seventeen taxa. Their black colour indicates that the fossils underwent substantial thermal alteration. However, it is suggested that preservation in a matrix of early diagenetic silica shielded them from the most destructive mechanical and chemical effects of metamorphism. Microbial mats and large acanthomorphic acritarchs suggest a coastal marine depositional environment; the acritarchs further indicate an early Vendian age for the sediments. The Scotia fossils bear a close resemblance to assemblages described from the Doushantuo Formation, China and elsewhere, demonstrating the broad geographical distribution of biostratigraphically important Vendian taxa. Briareus and Echinosphaeridium are described as new genera; Briareus borealis is described as a new species, while Echinosphaeridium maximum is proposed as a new combination.

Sleep characteristics are associated with incident cardiovascular diseases (CVD), but there is a lack of studies on the association between sleep characteristics and incidence/progression of coronary artery calcification (CAC). In the Heinz Nixdorf Recall Study, a population-based cohort study in Germany, CAC was assessed by electron-beam tomography at baseline and at 5-year follow-up. In an analysis set of 3043 subjects (age at baseline 45-74 years; 47% men), we fitted logistic and linear regression models to assess associations between self-rated sleep characteristics (nocturnal and total sleep duration; napping; various sleep disorders) and CAC incidence/CAC progression. Progression was measured as 5-year progression factor, as categories of absolute CAC change, and additionally characterized as rapid or slow compared to an extrapolation of baseline CAC values. We observed barely any association between sleep characteristics and CAC progression regardless of the chosen statistical approach; associations between sleep and CAC incidence were slightly larger, e.g., the geometric mean of the 5-year CAC progression factor was 6.8% (95% confidence interval: -9.5; 25.9) larger for ≤5 h, 2.9% (-7.3; 14.3) larger for 5.1-6.9 h and 7.1% (-2.4; 15.7) smaller for ≥7.5 h total sleep compared to 7- <7.5 h total sleep. For subjects with any regular sleep disorder, the geometric mean of the 5-year CAC progression was 3.5% (-4.7; 11.2) smaller compared to subjects without any regular sleep disorder. In this German cohort study, sleep characteristics were barely associated with CAC progression. Copyright © 2018 Elsevier B.V. All rights reserved.

[Phenomenological anthropological social psychiatry--paving the way for a theoretical reanimation].

PubMed

Thoma, Samuel

2012-11-01

This article tries to link the present lack of theoretical discussion within German Social Psychiatry with a loss of phenomenological and anthropological thought. The so-called Phenomenological Psychiatry used to play a very important role in German psychiatry during the 50 ies until the 70 ies and had strong influences on the first reformers of German psychiatry, such as Walter Ritter von Baeyer, Heinz Häfner, Caspar Kulenkampff, Karl Peter Kisker and Erich Wulff. Their reforms were not only founded by a social criticism put forth by theories such as marxism (Basaglia, Wulff) or structuralism (Foucault) but also by a concrete notion of what it is like to suffer from mental illness and what kind of needs are linked to such suffering. This very notion was given by the phenomenological approach. Finally the article tries to give reasons for today's reciprocal loss of connection of the phenomenological and the socio-psychiatric school. © Georg Thieme Verlag KG Stuttgart · New York.

2012-01-01

Carl Arthur Scheunert (1879-1957) was a German scientist who supervised several studies with prisoners that were designed to assess the optimal vitamin and nutrient supply, and were conducted by his associate Karl-Heinz Wagner (1911-2007) from 1938 to 1943. This contribution describes the aims, results and conclusions of Scheunert's research 1923 to 1945 in comparison with the national and international vitamin research and its consequences for public health measures. Conditions and results of the human experiments are reconstructed and compared with similar studies performed in other countries. Burden as well as health risks for the study participants are assessed. In addition, it is discussed whether general rules for human experimentation were followed (e.g. informed consent and minimizing of health risks). Although the available documents support the conclusion that no deaths or lasting injuries were caused, the experiments violated ethical standards, in particular because of the conditions in the Waldheim prison including progressive deterioration of nutrition and health.

Recovery of handwritten text from the diaries and papers of David Livingstone

NASA Astrophysics Data System (ADS)

Knox, Keith T.; Easton, Roger L., Jr.; Christens-Barry, William A.; Boydston, Kenneth

2011-03-01

During his explorations of Africa, David Livingstone kept a diary and wrote letters about his experiences. Near the end of his travels, he ran out of paper and ink and began recording his thoughts on leftover newspaper with ink made from local seeds. These writings suffer from fading, from interference with the printed text and from bleed through of the handwriting on the other side of the paper, making them hard to read. New image processing techniques have been developed to deal with these papers to make Livingstone's handwriting available to the scholars to read. A scan of the David Livingstone's papers was made using a twelve-wavelength, multispectral imaging system. The wavelengths ranged from the ultraviolet to the near infrared. In these wavelengths, the three different types of writing behave differently, making them distinguishable from each other. So far, three methods have been used to recover Livingstone's handwriting. These include pseudocolor (to make the different writings distinguishable), spectral band ratios (to remove text that does not change), and principal components analysis (to separate the different writings). In initial trials, these techniques have been able to lift handwriting off printed text and have suppressed handwriting that has bled through from the other side of the paper.

Vital forces and organization: philosophy of nature and biology in Karl Friedrich Kielmeyer.

PubMed

Gambarotto, Andrea

2014-12-01

The historical literature on German life science at the end of the 18th century has tried to rehabilitate eighteenth century vitalism by stressing its difference from Naturphilosophie. Focusing on the work of Karl Friedrich Kielmeyer this paper argues that these positions are based on a historiographical bias and that the clear-cut boundary between German vitalism and Naturphilosophie is historically unattested. On the contrary, they both belong to the process of conceptual genealogy that contributed to the project of a general biology. The latter emerged as the science concerned with the laws that regulate the organization of living nature as a whole. The focus on organization was, at least partially, the result of the debate surrounding the notion of "vital force", which originated in the mid-eighteenth century and caused a shift from a regulative to a constitutive understanding of teleology.

Clever Hans and his effects: Karl Krall and the origins of experimental parapsychology in Germany.

De Sio, Fabio; Marazia, Chantal

2014-12-01

Shortly before the outbreak of World War I, the so-called Elberfeld horses, the counting and speaking animals, were among the most debated subjects of the newborn comparative psychology. Yet, they have left little trace in the historiography of this discipline, mostly as an appendix of the more famous Clever Hans. Their story is generally told as the prelude to the triumph of reductionistic experimental psychology. By paying a more scrupulous attention than has so far being done to the second life of Hans, and to the endeavours of his second master, Karl Krall, this article explores the story of the Elberfeld horses as an important, if so far neglected, chapter in the history of experimental parapsychology.

New software for computer-assisted dental-data matching in Disaster Victim Identification and long-term missing persons investigations: "DAVID Web".

PubMed

Clement, J G; Winship, V; Ceddia, J; Al-Amad, S; Morales, A; Hill, A J

2006-05-15

In 1997 an internally supported but unfunded pilot project at the Victorian Institute of Forensic Medicine (VIFM) Australia led to the development of a computer system which closely mimicked Interpol paperwork for the storage, later retrieval and tentative matching of the many AM and PM dental records that are often needed for rapid Disaster Victim Identification. The program was called "DAVID" (Disaster And Victim IDentification). It combined the skills of the VIFM Information Technology systems manager (VW), an experienced odontologist (JGC) and an expert database designer (JC); all current authors on this paper. Students did much of the writing of software to prescription from Monash University. The student group involved won an Australian Information Industry Award in recognition of the contribution the new software could have made to the DVI process. Unfortunately, the potential of the software was never realized because paradoxically the federal nature of Australia frequently thwarts uniformity of systems across the entire country. As a consequence, the final development of DAVID never took place. Given the recent problems encountered post-tsunami by the odontologists who were obliged to use the Plass Data system (Plass Data Software, Holbaek, Denmark) and with the impending risks imposed upon Victoria by the decision to host the Commonwealth Games in Melbourne during March 2006, funding was sought and obtained from the state government to update counter disaster preparedness at the VIFM. Some of these funds have been made available to upgrade and complete the DAVID project. In the wake of discussions between leading expert odontologists from around the world held in Geneva during July 2003 at the invitation of the International Committee of the Red Cross significant alterations to the initial design parameters of DAVID were proposed. This was part of broader discussions directed towards developing instruments which could be used by the ICRC's "The Missing

Curved spaces before Einstein: Karl Schwarzschild's cosmological speculations and the beginnings of relativistic cosmology (German Title: Gekrümmte Universen vor Einstein: Karl Schwarzschilds kosmologische Spekulationen und die Anfänge der relativistischen Kosmologie)

NASA Astrophysics Data System (ADS)

Schemmel, Matthias

In contrast to most of his collegues in astronomy and physics, the German astronomer Karl Schwarzschild immediately recognized the significance of general relativity for physics and astronomy, and played a pioneering role in its early development. In this contribution, it is argued that the clue for understanding Schwarzschild's exceptional reaction to general relativity lies in the study of his prerelativistic work. Long before the rise of general relativity, Schwarzschild occupied himself with foundational problems on the borderline of physics, astronomy, and mathematics that, from today's perspective, belong to the field of problems of that theory. In this contribution, the example of Schwarzschild's early speculations about the non-Euclidean nature of physical space on cosmological scales is presented and their reflection in his reception of general relativity is discussed.

To examine if there is a cross-sectional relationship of depression and MCI and to examine if the relationship differs depending on the type of depression (currently elevated depressive symptoms or a positive history of lifetime depression or both) and on the MCI subtype (amnestic versus non-amnestic MCI (aMCI/naMCI)). From the second examination of the population-based Heinz Nixdorf Recall study (50% men, 50-80 years), 583 participants with MCI (aMCI n = 304; naMCI n = 279) and 1,446 cognitively normal participants were included in the analyses. Currently elevated depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D; score ≥18). Furthermore, participants were asked if they have ever received a previous diagnosis of depression. Log-Poisson regression models (adjusted for sociodemographic/cardiovascular risk factors) were calculated to determine the association of MCI and its subtypes with all depression variables. The fully adjusted prevalence rate ratios for MCI, aMCI, and naMCI in depressed versus non-depressed participants were 2.06 (95% confidence interval, 1.60-2.64), 3.06 (2.21-4.23), and 1.93 (1.46-2.57). A positive history of lifetime depression without current depressive symptoms was solely associated with naMCI (1.31 (0.99-1.73)). These results suggest that the relationship of depression/depressive symptoms and MCI might differ depending on the timing of depression and on the MCI subtype. Our longitudinal follow-up will allow us to further elucidate this relationship.

Injury assessment of birds following the Deepwater Horizon (DWH) oil spill in 2010 was part of the Natural Resource Damage Assessment. One reported effect was hemolytic anemia with the presence of Heinz bodies (HB) in birds, however, the role of route and magnitude of exposure to oil is unknown. The purpose of the present study was to determine if double-crested cormorants (Phalacocorax auritis; DCCO) exposed orally and dermally to artificially weathered crude oil would develop hemolytic anemia including HB and reticulocytosis. In the oral experiment, sub-adult, mixed-sex DCCOs were fed control (n = 8) or oil-injected fish with a daily target dose of 5 (n = 9) or 10 (n = 9) ml oil/kg for 21 days. Then, subadult control (n = 12) and treated (n = 13) cormorant groups of similar sex-ratio were dermally treated with approximately 13ml of water or weathered MC252 crude oil, respectively, every 3 days for 6 dosages approximating 20% surface coverage. Collected whole blood samples were analyzed by light (new methylene blue) and transmission electron microscopy. Both oral and dermal treatment with weathered DWH MC252 crude oil induced regenerative, but inadequately compensated, anemia due to hemolysis and hematochezia as indicated by decreased packed cell volume, relative increase in reticulocytes with lack of difference in corrected reticulocyte count, and morphologic evidence of oxidant damage at the ultrastructural level. Hemoglobin precipitation, HB formation, degenerate organelles, and systemic oxidant damage were documented. Heinz bodies were typically <2µm in length and smaller than in mammals. These oblong cytoplasmic inclusions were difficult to see upon routine blood smear evaluation and lacked the classic button appearance found in mammalian red blood cells. They could be found as light, homogeneous blue inclusions upon new methylene blue staining. Ultrastructurally, HB appeared as homogeneous, electron-dense structures within the cytosol and lacked membranous

David Kasner, MD (1927–2001), used his extensive dissections of eye bank eyes and experiences in teaching cataract surgery to resident physicians to realize that excision of vitreous when present in the anterior chamber of eyes undergoing cataract surgery was preferable to prior intraoperative procedures. Noting that eyes tolerated his maneuvers, he then performed planned subtotal open-sky vitrectomies; first on a traumatized eye in 1961, then on two eyes of patients with amyloidosis (1966–1967). The success of these operations was noted by others, most particularly Robert Machemer, MD. Kasner’s work directly led to further surgical developments, including closed pars plana vitrectomy.

The knowledge of the shape of an artwork is an important element for its study and conservation. When dealing with a statue, roughness measurement is a very useful contribution to document its surface conditions, to assess either changes due to restoration intervention or surface decays due to wearing agents, and to monitor its time-evolution in terms of shape variations. In this work we present the preliminary results of the statistical analysis carried out on acquired data relative to six areas of the Michelangelo"s David marble statue, representative of differently degraded surfaces. Determination of the roughness and its relative characteristic wavelength is shown.

Imaging inert fluorinated gases in cracks: perhaps in David's ankles.

PubMed

Kuethe, Dean O; Scholz, Markus D; Fantazzini, Paola

2007-05-01

Inspired by the challenge of determining the nature of cracks on the ankles of Michelangelo's statue David, we discovered that one can image SF(6) gas in cracks in marble samples with alacrity. The imaging method produces images of gas with a signal-to-noise ratio (SNR) of 100-250, which is very high for magnetic resonance imaging (MRI) in general, let alone for an image of a gas at thermal equilibrium polarization. To put this unusual SNR in better perspective, we imaged SF(6) in a crack in a marble sample and imaged the lung tissue of a live rat (a more familiar variety of sample to many MRI scientists) using the same pulse sequence, the same size coils and the same MRI system. In both cases, we try to image subvoxel thin sheets of material that should appear bright against a darker background. By choosing imaging parameters appropriate for the different relaxation properties of SF(6) gas versus lung tissue and by choosing voxel sizes appropriate for the different goals of detecting subvoxel cracks on marble versus resolving subvoxel thin sheets of tissue, the SNR for voxels full of material was 220 and 14 for marble and lung, respectively. A major factor is that we chose large voxels to optimize SNR for detecting small cracks and we chose small voxels for resolving lung features at the expense of SNR. Imaging physics will cooperate to provide detection of small cracks on marble, but David's size poses a challenge for magnet designers. For the modest goal of imaging cracks in the left ankle, we desire a magnet with an approximately 32-cm gap and a flux density of approximately 0.36 T that weighs <500 kg.

Memories of David Kirzhnits

In the mid-1950s, a new staff member appeared at the Theory Division of the Physical Institute of the Academy of Sciences (FIAN): David Abramovich Kirzhnits. A Moscow State University alumnus, after graduation he had been assigned to a large defense plant in the city of Gorky, where he had worked for several years as an engineer. He was "liberated" from there by Igor Evgenyevich Tamm, our department head, who managed to transfer him to FIAN. Igor Evgenyevich knew D. A. Kirzhnits - they had met in Moscow before Kirzhnits finished university. At that time Kirzhnits was performing thesis work with professor A. S. Kompaneyets as academic adviser. At his adviser's suggestion, D. Kirzhnits consulted with I. E. Tamm on questions pertaining to the thesis topic. I. E. Tamm took a great liking for the diploma student, and he even wanted to recruit D. A. Kirzhnits for the Theory Division immediately after graduation. But at that time (1949) this proved impossible for several reasons. First, D. Kirzhnits was, as they say, an "invalid of the fifth group" - a Jew - which during those years of violent struggle against cosmopolitanismb often proved an obstacle in looking for work. Second, during the years of mass repressions D. Kirzhnits' father had been arrested on treason charges (according to the charges, he had wanted to sell the Far East to Japan). After intensive investigation his father was released, but he lived only a little longer. Reports of this also could have impeded his acceptance. Third, Igor Evgenyevich didn't have enough weight in officials' eyes at that time and so was unable to overcome "first" and "second."...

The results of the bacteriological surveillance cultures for 26 patients with bone marrow transplantation (Karl Marx University Leipzig, G.D.R., 1985-1987) are presented. 5.9% of all surveillance cultures contained facultatively pathogenic germs (with Pseudomonas aeruginosa as the most frequent representative, which was the reason of a sepsis in two patients). Coagulasenegative Staphylococci and other germs with an obscure pathogenicity were isolated upon a large scale, especially from the mucous membrane regions. There are hints, that above all special strains of coagulasenegative Staphylococci "colonize" the patient's body (also for longer periods) and turn into the blood too. During the total decontamination intestinal anaerobic flora is absent. After closing of total decontamination Clostridium perfringens is the first detectable anaerobic species. During the selective decontamination systemic applications of antibiotics are able to obliterate anaerobic findings for certain periods. Recommendations for an effective arrangement of the surveillance cultures of bone marrow transplantation patients are given.

Repeating ice-earthquakes beneath David Glacier from the 2012-2015 TAMNNET array

Walter, J. I.; Peng, Z.; Hansen, S. E.

2017-12-01

The continent of Antarctica has approximately the same surface area as the continental United States, though we know significantly less about its underlying geology and seismic activity. In recent years, improvements in seismic instrumentation, battery technology, and field deployment practices have allowed for continuous broadband stations throughout the dark Antarctic winter. We utilize broadband seismic data from a recent experiment (TAMNNET), which was originally proposed as a structural seismology experiment, for seismic event detection. Our target is to address fundamental questions about regional-scale crustal and environmental seismicity in the study region that comprises the Transantarctic Mountain area of Victoria and Oates Land. We identify most seismicity emanating from David Glacier, upstream of the Drygalski Ice Tongue, which has been documented by several other studies. In order to improve the catalog completeness for the David Glacier area, we utilize a matched-filter technique to identify potential missing earthquakes that may not have been originally detected. This technique utilizes existing cataloged waveforms as templates to scan through continuous data and to identify repeating or nearby earthquakes. With a more robust catalog, we evaluate relative changes in icequake positions, recurrence intervals, and other first-order information. In addition, we attempt to further refine locations of other regional seismicity using a variety of methods including body and surface wave polarization, beamforming, surface wave dispersion, and other seismological methods. This project highlights the usefulness of archiving raw datasets (i.e., passive seismic continuous data), so that researchers may apply new algorithms or techniques to test hypotheses not originally or specifically targeted by the original experimental design.

Cutting edge issues in allergy and clinical immunology.

PubMed

Matthias, Torsten; Shoenfeld, Yehuda

2007-02-01

Approximately every 5 yr, Clinical Reviews in Allergy and Immunology deviates from its usual practice of publishing volumes devoted to one theme to including papers that cover a range of subjects. This issue is one such exception and arose following a symposium at the International Institute for Research in Autoimmune Diseases named AESKU.KIPP Institute at their Wendelsheim facility. The AESKU.KIPP Institute was a particularly venue because it was initially established by a German diagnostic company and a Swiss benefactor, Karl- Heinz Kipp. The goal of the Institute was to develop a unique atmosphere to encourage original research in the field of autoimmunity and clinical immunology. The thought was to create an institute where young scientists from throughout the world could come for short periods of time to learn newer methodologies in both clinical immunology and also molecular biology. This theme contains several of the papers presented at the opening of the Institute and are incorporated herein because they focus on several unique aspects of clinical immunology, often referred to as the mosaic of autoimmunity.

Occupational exposure to manganese (Mn) has been associated with impairments in olfaction and motor functions, but it has yet to be determined if such effects persist upon cessation of exposure. The objective of this study was to evaluate the influence of former occupational Mn exposure on olfaction within the framework of a prospective cohort study among an elderly German population. Information on job tasks with recognized Mn exposure and data on odor identification assessed with Sniffin' sticks was collected during the second follow-up of the Heinz Nixdorf Recall Study. The study population consisted of 1385 men aged 55-86 years, 354 of whom ever worked in jobs with potential Mn exposure (median 58.3μg/m 3  years, interquartile range 19.0-185μg/m 3  years). Multiple exposure measures, including job tasks, cumulative Mn exposure, and Mn determined in blood samples (MnB) archived at baseline, were used to estimate effects of Mn on olfaction. Having ever worked as welder was associated with better olfaction compared to other blue-collar workers without Mn exposure. Blue-collar workers identified less odors in comparison to white-collar workers. Concentrations of previous Mn exposure >185μg/m 3  years or MnB ≥15μg/L were not associated with impaired olfaction. In addition to a strong age effect, participants with lower occupational qualification identified less odors. We found no relevant association of former Mn exposure at relatively low levels with impaired olfaction. Possible neurotoxic Mn effects may not be persistent after cessation.

Dumoulin, Jean-Guy; Mamen, Rolf

1995-01-01

The comprehensive integration and environmental (including RF) test facilities of the Canadian Space Agency's David Florida Laboratory (CSA)(DFL) were used extensively for the MSAT Program. Following a description of the facilities, the paper outlines their application to the qualification of the two MSAT satellites following an overview of the test plan. Particular emphasis is given to passive intermodulation measurement (PIM) demands, which for the MSAT satellites, contributed to the need to extend the anechoic chamber. The extended chamber was also used for an EMC test and SAR signature test of the RADARSAT satellite. The DFL's facilities are being used for additional aspects of mobile satellite communications. One shielded anechoic Extra High Frequency (EHF) chamber and associated test equipment are employed predominantly for measuring the performance of the IRIDIUM satellites' Engineering Model Gateway Moveable Antennas (EM)(GMA). Other chambers are used for testing aeronautical antennas on behalf of Inmarsat. Still others combine thermal and PIM testing. The paper concludes with a review of the test requirements of evolving satcom missions such as Inmarsat Aero-1.

Eurekan deformation has been proven to be a complex sequence of tectonic episodes, dominated by compression in the Circum Arctic region. It was associated with early Cenozoic collision of Eurasia, North America and Greenland plates producing fold-thrust belt style of deformation. Timing of this enigmatic event has not yet been extensively resolved by radiometric dating (Piepjohn et al. 2016, Journal of the Geological Society, 173(6), 1007-1024). Reinhardt et al. (2013, Z. Dt. Ges. Geowiss., 164 (1), 131-147) dated syn-tectonic volcanic ashes at c. 60 Ma and 54 Ma on Ellesmere Island, Canada. Tagner et al. (2011, Earth and Planetary Science Letters, 303(3), 203-214) interpreted c. 49-47 Ma 40Ar/39Ar ages on trachyte flows in northern Greenland as peak compression during the Eurekan event.

(2001, Geologisches Jahrbuch, B 91, 83-104) reported K/Ar whole rock ages ranging from c. 67 to 49 Ma for the slates from Svartfjella-Eidembukta-Daudmannsodden Lineament. Bentonite layers in the Central Tertiary Basin are as young as c. 56 Ma (Charles et al. 2011, Geochem. Geophys. Geosyst., 12, 1-19), predating latest deformation. Moreover, Barnes et al (2017, in prep.) applied (U-Th)/He thermochronology along the western margin of Svalbard and resolved Early to Middle Eocene heating, likely documenting burial related to thrusting. Here we present new results from 40Ar/39Ar muscovite dating of ductile to brittle shear zone on Prins Karls Forland, Svalbard, indicating Eurekan age of thrusting. Prins Karls Forland is dominated by Neoproterozoic siliciclastic metasediments (comprising Caledonian basement) regionally metamorphosed to greenschist facies conditions.

The evolution of rapidly intensifying Hurricane Karl (2010) is examined from a suite of remote sensing observations during the NASA Genesis and Rapid Intensification Processes (GRIP) field experiment. The novelties of this study are in the analysis of data from the airborne Doppler radar HIWRAP and the new Global Hawk airborne platform that allows long endurance sampling of hurricanes. Supporting data from the HAMSR microwave sounder coincident with HIWRAP and coordinated flights with the NOAA WP-3D aircraft help to provide a comprehensive understanding of the storm. The focus of the analysis is on documenting and understanding the structure, evolution and role of small scale, deep convective forcing in the storm intensification process. Deep convective bursts are sporadically initiated in the downshear quadrants of the storm and rotate into the upshear quadrants for a period of 12 h during the rapid intensification. The aircraft data analysis indicates that the bursts are being formed and maintained through a combination of two main processes: (1) convergence generated from counter-rotating mesovortex circulations and the larger vortex-scale flow and (2) the turbulent (scales of 25 km) transport of anomalously warm, buoyant air from the eye to the eyewall at low levels. The turbulent mixing across the eyewall interface and forced convective descent adjacent to the bursts assists in carving out the eye of Karl, which leads to an asymmetric enhancement of the warm core. The mesovortices play a key role in the evolution of the features described above.The Global Hawk aircraft allowed an examination of the vortex response and axisymmetrization period in addition to the burst pulsing phase. A pronounced axisymmetric development of the vortex is observed following the pulsing phase that includes a sloped eyewall structure and formation of a clear, wide eye.

Determination of water traces in various organic solvents using Karl Fischer method under FIA conditions.

PubMed

Dantan, N; Frenzel, W; Küppers, S

2000-05-31

Flow injection methods utilising the Karl Fischer (KF) reaction with spectrophotometric and potentiometric detection are described for the determination of the trace water content in various organic solvents. Optimisation of the methods resulted in an accessible (linear) working range of 0.01-0.2% water for many solvents studied with a typical precision of 1-2% R.S.D. Only 50 mul of organic solvent was injected and the sampling frequency was about 120 samples per h. Since the slopes of the calibration curves were different for different solvents appropriate calibration was required. Problems associated with spectrophotometric detection and caused by refractive index changes were pointed out and a nested-loop configuration was proposed to overcome this kind of interference. The potentiometric method with a novel flow-through detector cell was shown to surpass the performance of spectrophotometric detection in any respect. The characteristics of the procedures developed made them well applicable for on-line monitoring of technical solvent distillations in an industrial plant.

David Malament and the Conventionality of Simultaneity: A Reply

NASA Astrophysics Data System (ADS)

Grünbaum, Adolf

2010-10-01

In 1977, David Malament proved the valuable technical result that the simultaneity relation of standard synchrony ɛ=1/2 with respect to an inertial observer O is uniquely definable in terms of the relation κ of causal connectibility. And he claimed that this definability undermines my own version of the conventionality of metrical simultaneity within an inertial frame. But Malament’s proof depends on the imposition of several supposedly “innocuous” constraints on any candidate for the simultaneity relation relative to O. Relying on Allen I. Janis’s 1983 challenge to one of these constraints, I argue that Malament’s technical result did not undermine my philosophical construal of the ontological status of relative metrical simultaneity. Furthermore, I show that (a) Michael Friedman’s peremptorily substantivalist critique of my conception, which Malament endorses, is ill-founded, and (b) if Malament had succeeded in discrediting my own conventionalist version of metrical simultaneity, he would likewise have invalidated Einstein’s pioneering version of it.

Investigations of adverse effects of air pollution (AP) and ambient noise on cognitive functions are apparently scarce, and findings seem to be inconsistent. The aim of this study was to examine the associations of long-term exposure to AP and traffic noise with cognitive performance. At the second examination of the population-based Heinz Nixdorf Recall study (2006-2008), cognitive performance was evaluated in 4086 participants. Long-term residential exposure to size-specific particulate matter (PM) and nitrogen oxides (NOx) with land use regression, to and traffic noise (weighted 24-h (L DEN ) and nighttime (L NIGHT ) means), was assessed according to the European Union (EU) Directive 2002/49/EC. Multiple regression models were calculated for the relationship of environmental exposures with a global cognitive score (GCS) and in five cognitive subtests, using single- and two-exposure models. In fully adjusted models, several AP metrics were negatively associated with four of five subtests and with GCS. For example, an interquartile range increase in PM 2.5 was correlated with verbal fluency, labyrinth test, and immediate and delayed verbal recall. A 10 dB(A) elevation in L DEN and L NIGHT was associated with GCS. Similar but not significant associations were found for the cognitive subtests. In two-exposure models including noise and air pollution simultaneously, the associations did not change markedly for air pollution, but attenuated numerically for noise. Long-term exposures to AP and traffic noise are negatively correlated with subtests related to memory and executive functions. There appears to be little evidence for mutual confounding.

Genesis of Karl Popper's EPR-like experiment and its resonance amongst the physics community in the 1980s

NASA Astrophysics Data System (ADS)

Del Santo, Flavio

2018-05-01

I present the reconstruction of the involvement of Karl Popper in the community of physicists concerned with foundations of quantum mechanics, in the 1980s. At that time Popper gave active contribution to the research in physics, of which the most significant is a new version of the EPR thought experiment, alleged to test different interpretations of quantum mechanics. The genesis of such an experiment is reconstructed in detail, and an unpublished letter by Popper is reproduced in the present paper to show that he formulated his thought experiment already two years before its first publication in 1982. The debate stimulated by the proposed experiment as well as Popper's role in the physics community throughout 1980s is here analysed in detail by means of personal correspondence and publications.

PEOPLE IN PHYSICS: David Bohm and the implicate order: a new paradigm for physics teachers

David Bohm (1917-93) was a highly original and individual physicist. His novel ideas and profound intuition extended not only to the physical world but also to the nature of consciousness and society. Bohm regarded science as having become essentially fragmented in its approach to understanding physical reality and sought a more holistic physics based on order, transformation and flowing movement. His notion of an implicate order provides an unusual and exciting challenge for both teachers and students alike.

Prison break: Karl Menninger's The Crime of Punishment and its reception in U.S. psychology.

PubMed

Devonis, David C; Triggs, Jessica

2017-02-01

In 1968, Karl Menninger, a highly visible and vocal U.S. psychiatrist, published a call to action on prison reform, The Crime of Punishment (Menninger, 1966/1968). This widely circulated book's central idea is that punishment as practiced in penal settings is an injustice amounting to a crime. At the outset, The Crime of Punishment quickly achieved national attention. Within mainstream psychology, its antipunishment message encountered a changed climate in which punishment, thought ineffective during the period 1930 through 1960, was redefined as an effective component in learning. It also met competition from the contemporaneous Stanford Prison Experiment (Haney, Banks, & Zimbardo, 1973), which quickly rose to equivalent media presence and superior disciplinary prominence. Both the Stanford Prison Experiment and The Crime of Punishment survived in the antireform era of hyperincarceration after 1974 as parallel examples of reform activism, one secular and one religious in character, illustrating some convergences of aim between psychology and psychiatry outside of specifically clinical issues.

The present article elucidates the role and function of SS Gruppenführer Karl Blumenreuter (1881-1969), the leading pharmacist of the SS. The aim is to clarify how he participated in the crimes of the Nazi Party and especially the SS during the "Third Reich" and the extent to which he was brought to justice after 1945. Central elements of the study are based on researched archival primary sources. The latter were compared with each other and supplemented with the currently available secondary literature on the subject. It can be established that Blumenreuter was a zealous National Socialist with marked career ambitions who advanced within the SS to the rank of SS Gruppenführer and Lieutenant General of the Waffen SS (Generalleutnant der Waffen SS). He supplied pre-measured phenol ampoules for the murder of prisoners in the concentration camps. Blumenreuter furthermore organised equipment and material supplies for various experiments on humans. After 1945 he succeeded in playing down his participation in the crimes in the time of National Socialism. Blumenreuter died in 1969 without having being brought to justice by the judiciary and without having reflected self-critically on his role in the "Third Reich".

The Heinz Nixdorf Recall Study is an ongoing population-based prospective cardiovascular cohort study of the Ruhr area in Germany. This paper focuses on the recruitment strategy and its response results including a comparison of participants of the baseline examination with nonparticipants. Random samples of the general population were drawn from residents' registration offices including men and women aged 45-74 years. We used a multimode contact approach including an invitational letter, a maximum of two reminder letters and phone calls for the recruitment of study subjects. Nonparticipants were asked to fill in a short questionnaire. We calculated proportions of response, contact, cooperation and recruitment efficacy to characterize the participation. Overall, 4487 eligible subjects participated in our study. Although the elderly (65-75 years) had the highest contact proportion, the cooperation proportion was the lowest among both men and women. The recruitment efficacy proportion was highest among subjects aged 55-64 years. The identifiability of the phone number of study subjects was an important determinant of response. The recruitment efficacy proportion among subjects without an identified phone number was 11.4% as compared to 65.3% among subjects with an identified phone number. The majority of subjects agreed to participate after one invitational letter only (52.6%). A second reminding letter contributed only very few participants to the study. Nonparticipants were more often current smokers than participants and less often belonged to the highest social class. Living in a regular relationship with a partner was more often reported among participants than nonparticipants.

David Stafford-Clark (1916-1999): Seeing through a celebrity psychiatrist.

2017-04-26

This article uses the mass-media career of the British psychiatrist David Stafford-Clark (1916-1999) as a case study in the exercise of cultural authority by celebrity medical professionals in post-war Britain. Stafford-Clark rose to prominence in the mass media, particularly through his presenting work on medical and related topics for BBC TV and Radio, and was in the vanguard of psychiatrists and physicians who eroded professional edicts on anonymity. At the height of his career, he traded upon his celebrity status, and consequent cultural authority, to deliver mass media sermons on a variety of social, cultural, and political topics. Stafford-Clark tried to preserve his sense of personal and intellectual integrity by clinging to a belief that his authority in the public sphere was ultimately to be vindicated by his literary, intellectual, and spiritual significance. But as his credibility dwindled, he came to distrust the cultural intermediaries, such as broadcasters and publishers, who had supported him.

In early 1970s first personal desk-top computers started to be available in hospitals. Mr Price was one of the pioneers introducing his own software to identify Marmarou's model of CSF space during infusion studies to diagnose patients suffering from hydrocephalus. His closed-loop control system for infusion of mannitol to manage patients at risk of intracranial hypertension was designed in 1977. The system worked successfully for 10 years in Pinderfields Hospital in Wakefield, UK. In the middle 1980's he initiated international cooperation with Children's Health Centre in Poland in long-term computer-assisted monitoring and analysis of ICP. Software designed in a course of this cooperation paved the way for contemporary package of ICM+ (Intensive Care Monitor, University of Cambridge, UK). Our scientific portfolio from these years (1985-1995) contains hundreds of head injured patients with waveform ICP analysis, introduction of compensatory reserve index RAP, few highly cited papers. Now, we understand ICP much better thanks to David's personal passion and extremely friendly support.

Dave Keeling—only Roger Revelle called him "Charles David" and always in a tone that could command Dave's attention—had a remarkable influence on the creation of modern understanding of the oceanic CO2 system. Although Dave resided at an oceanographic institution for almost his entire professional career, the great majority of his work concerned atmospheric measurements; his own account of his work [Keeling, 1998] makes scant reference to his ocean science papers. But those relatively few oceanic papers, and more importantly his intense personal interest and unimpeachable reputation for classic measurement, had enormous impact. It is possible to trace Dave's influence on oceanic measurement through the course of five decades, and over that time, our understanding has grown enormously. The following is a somewhat personal account, but Dave so influenced the careers of the small group of ocean CO2 scientists that have led the way that any one of them would write a similar account.

In plants, fruit maturation and oxidative stress can induce small heat shock protein (sHSP) synthesis to maintain cellular homeostasis. Although the tomato reference genome was published in 2012, the actual number and functionality of sHSP genes remain unknown. Using a transcriptomic (RNA-seq) and evolutionary genomic approach, putative sHSP genes in the Solanum lycopersicum (cv. Heinz 1706) genome were investigated. A sHSP gene family of 33 members was established. Remarkably, roughly half of the members of this family can be explained by nine independent tandem duplication events that determined, evolutionarily, their functional fates. Within a mitochondrial class subfamily, only one duplicated member, Solyc08g078700, retained its ancestral chaperone function, while the others, Solyc08g078710 and Solyc08g078720, likely degenerated under neutrality and lack ancestral chaperone function. Functional conservation occurred within a cytosolic class I subfamily, whose four members, Solyc06g076570, Solyc06g076560, Solyc06g076540, and Solyc06g076520, support ∼57% of the total sHSP RNAm in the red ripe fruit. Subfunctionalization occurred within a new subfamily, whose two members, Solyc04g082720 and Solyc04g082740, show heterogeneous differential expression profiles during fruit ripening. These findings, involving the birth/death of some genes or the preferential/plastic expression of some others during fruit ripening, highlight the importance of tandem duplication events in the expansion of the sHSP gene family in the tomato genome. Despite its evolutionary diversity, the sHSP gene family in the tomato genome seems to be endowed with a core set of four homeostasis genes: Solyc05g014280, Solyc03g082420, Solyc11g020330, and Solyc06g076560, which appear to provide a baseline protection during both fruit ripening and heat shock stress in different tomato tissues.

We suggest an innovative approach to literary discourse by using corpus linguistic methods to address research questions from cognitive poetics. In this article, we focus on the way that readers engage in mind-modelling in the process of characterisation. The article sets out our cognitive poetic model of characterisation that emphasises the continuity between literary characterisation and real-life human relationships. The model also aims to deal with the modelling of the author’s mind in line with the modelling of the minds of fictional characters. Crucially, our approach to mind-modelling is text-driven. Therefore we are able to employ corpus linguistic techniques systematically to identify textual patterns that function as cues triggering character information. In this article, we explore our understanding of mind-modelling through the characterisation of Mr. Dick from David Copperfield by Charles Dickens. Using the CLiC tool (Corpus Linguistics in Cheshire) developed for the exploration of 19th-century fiction, we investigate the textual traces in non-quotations around this character, in order to draw out the techniques of characterisation other than speech presentation. We show that Mr. Dick is a thematically and authorially significant character in the novel, and we move towards a rigorous account of the reader’s modelling of authorial intention. PMID:29708113

Despite the importance of understanding the connection between air pollution exposure and diabetes, studies investigating links between air pollution and glucose metabolism in nondiabetic adults are limited. We aimed to estimate the association of medium-term air pollution exposures with blood glucose and glycated hemoglobin A1c (HbA1c) among nondiabetics. This study included observations from nondiabetic participants (n obs =7,108) of the population-based Heinz Nixdorf Recall study at baseline (2000–2003) and follow-up examination (2006–2008). Daily fine particulate matter (aerodynamic diameter≤2.5 μm, PM 2.5 ; aerodynamic diameter≤10 μm, PM 10 ), accumulation mode particle number (PN AM ), and nitrogen dioxide (NO 2 ) exposures were estimated at participants’ residences using the spatiotemporal European Air Pollution Dispersion (EURAD) chemistry transport model. We evaluated the associations between medium-term air pollution exposures (28- and 91-d means) and glucose metabolism measures using mixed linear regression and adjusting for season, meteorology, and personal characteristics. A range of other exposure windows (1-, 2-, 3-, 7-, 14-, 45-, 60-, 75-, 105-, 120-, and 182-d means) were also evaluated to identify potentially relevant biological windows. We observed positive associations between PM 2.5 and PN AM exposures and blood glucose levels [e.g., 28-d PM 2.5 : 0.91 mg/dL (95% CI: 0.38, 1.44) per 5.7 μg/m 3 ]. PM 2.5 , PM 10 , and PN AM exposures were positively associated with HbA1c [e.g., 91-d PM 2.5 : 0.07 p.p. (95% CI: 0.04, 0.10) per 4.0 μg/m 3 ]. Mean exposures during longer exposure windows (75- to 105-d) were most strongly associated with HbA1c, whereas 7- to 45-d exposures were most strongly associated with blood glucose. NO 2 exposure was not associated with blood glucose or with HbA1c. Medium-term PM and PN AM exposures were positively associated with glucose measures in nondiabetic adults. These findings indicate

On March 26, 1976, the NASA Flight Research Center opened its doors to hundreds of guests for the dedication of the center in honor of Hugh Latimer Dryden. The dedication was very much a local event; following Center Director David Scott’s opening remarks, the Antelope Valley High School’s symphonic band played the national anthem. Invocation was given followed by recognition of the invited guests. Dr. Hugh Dryden, a man of total humility, received praise from all those present. Dryden, who died in 1965, had been a pioneering aeronautical scientist who became director of the National Advisory Committee for Aeronautics (NACA) in 1949 and then deputy administrator of the NACA’s successor, NASA, in 1958. Very much interested in flight research, he had been responsible for establishing a permanent facility at the location later named in his honor. As Center Director David Scott looks on, Mrs. Hugh L.

S71-43788 (2 Aug. 1971) --- Astronaut David R. Scott, Apollo 15 commander, watches a geological hammer and a feather hit the lunar surface simultaneously in a test of Galileo's law of motion concerning falling bodies, as seen in this color reproduction taken from a transmission made by the RCA color television camera mounted on the Lunar Roving Vehicle (LRV). Scott released the hammer from his right hand and the feather from his left at the same instant. Galileo (1564-1642) was the great Italian astronomer and physicist. This experiment occurred toward the end of the third and final lunar surface extravehicular activity (EVA) by astronauts Scott and James B. Irwin, lunar module pilot. While Scott and Irwin descended in the Lunar Module (LM) to explore the moon, astronaut Alfred M. Worden, command module pilot, remained in the Command and Service Modules (CSM) in lunar orbit.

Continued Development of in Situ Geochronology for Planetary Using KArLE (Potassium-Argon Laser Experiment)

NASA Technical Reports Server (NTRS)

Devismes, D.; Cohen, B. A.

2016-01-01

Geochronology is a fundamental measurement for planetary samples, providing the ability to establish an absolute chronology for geological events, including crystallization history, magmatic evolution, and alteration events, and providing global and solar system context for such events. The capability for in situ geochronology will open up the ability for geochronology to be accomplished as part of lander or rover complement, on multiple samples rather than just those returned. An in situ geochronology package can also complement sample return missions by identifying the most interesting rocks to cache or return to Earth. The K-Ar radiometric dating approach to in situ dating has been validated by the Curiosity rover on Mars as well as several laboratories on Earth. Several independent projects developing in situ rock dating for planetary samples, based on the K-Ar method, are giving promising results. Among them, the Potassium (K)-Argon Laser Experiment (KArLE) at MSFC is based on techniques already in use for in planetary exploration, specifically, Laser-induced Breakdown Spectroscopy (LIBS, used on the Curiosity Chemcam), mass spectroscopy (used on multiple planetary missions, including Curiosity, ExoMars, and Rosetta), and optical imaging (used on most missions).

The purpose of this article is to summarize the work and pioneering achievements in the field of orthopedic surgery of the German orthopedic surgeon Karl Ludloff. Ludloff had an impact in the diagnostics, physical examination, orthopedic imaging, and orthopedic surgical technique of his era. He was a pioneer in the surgical treatment of dysplastic hip, anterior cruciate ligament reconstruction, and hallux valgus. His surgical technique for the correction of hallux valgus, initially stabilized with plaster of Paris, remained unpopular among other orthopedic surgeons for decades. In the 1990s, the advent and use of improved orthopedic materials for fixation attracted the interest of numerous orthopedic surgeons in the Ludloff osteotomy for its ability to correct the deformity in all 3 dimensions, its anatomic outcomes, and its low recurrence rate and patient satisfaction.

Aim The sleep disturbing effect of many drugs is derived from clinical trials with highly selected patient collectives. However, the generalizability of such findings to the general population is questionable. Our aim was to assess the association between intake of drugs labelled as sleep disturbing and self‐reported nocturnal sleep disturbances in a population‐based study. Methods We used data of 4221 participants (50.0% male) aged 45 to 75 years from the baseline examination of the Heinz Nixdorf Recall Study in Germany. The interview provided information on difficulties falling asleep, difficulties maintaining sleep and early morning arousal. We used the summary of product characteristics (SPC) for each drug taken and assigned the probability of sleep disturbances. Thereafter, we calculated cumulative probabilities of sleep disturbances per subject to account for polypharmacy. We estimated prevalence ratios (PR) using log Poisson regression models with robust variance. Results The adjusted PRs of any regular nocturnal sleep disorder per additional sleep disturbing drug were 1.01 (95% confidence interval (CI) 0.97, 1.06) and 1.03 (95% CI 1.00, 1.07) for men and women, respectively. Estimates for each regular nocturnal sleep disturbance were similarly close to 1. PRs for regular nocturnal sleep disturbances did not increase with rising cumulative probability for drug‐related sleep disturbances. Conclusions SPC‐based probabilities of drug‐related sleep disturbances showed barely any association with self‐reported regular nocturnal sleep disturbances. We conclude that SPC‐based probability information may lack generalizability to the general population or may be of limited data quality. PMID:27279554

Karl Pribram, the James Arthur Lectures, and What Makes Us Human

2006-01-01

Background The annual James Arthur lecture series on the Evolution of the Human Brain was inaugurated at the American Museum of Natural History in 1932, through a bequest from a successful manufacturer with a particular interest in mechanisms. Karl Pribram's thirty-ninth lecture of the series, delivered in 1970, was a seminal event that heralded much of the research agenda, since pursued by representatives of diverse disciplines, that touches on the evolution of human uniqueness. Discussion In his James Arthur lecture Pribram raised questions about the coding of information in the brain and about the complex association between language, symbol, and the unique human cognitive system. These questions are as pertinent today as in 1970. The emergence of modern human symbolic cognition is often viewed as a gradual, incremental process, governed by inexorable natural selection and propelled by the apparent advantages of increasing intelligence. However, there are numerous theoretical considerations that render such a scenario implausible, and an examination of the pattern of acquisition of behavioral and anatomical novelties in human evolution indicates that, throughout, major change was both sporadic and rare. What is more, modern bony anatomy and brain size were apparently both achieved well before we have any evidence for symbolic behavior patterns. This suggests that the biological substrate underlying the symbolic thought that is so distinctive of Homo sapiens today was exaptively achieved, long before its potential was actually put to use. In which case we need to look for the agent, perforce a cultural one, that stimulated the adoption of symbolic thought patterns. That stimulus may well have been the spontaneous invention of articulate language. PMID:17134484

Poor sleep quality as well as short and long sleep duration has been linked to type 2 diabetes. In addition to confirmational analyses, we examined the impact of daytime napping on incident diabetes, and we assessed associations between sleep characteristics and incident prediabetes. In a subgroup of the Heinz Nixdorf Recall Study, a population-based cohort study in Germany (N = 2962; age 45-75 years, without history of cancer, stroke, or cardiovascular diseases), diabetes at baseline and at 5-year follow-up was assessed by self-report and measurement of serum glucose levels. Prediabetes was defined as impaired fasting glucose (6.1-6.9 mmol/L). A sleep questionnaire was used to assess difficulties falling asleep, difficulties maintaining sleep, early morning arousal, and duration of nocturnal and daytime sleep. In adjusted regression models, short (≤5 hours) and long (≥7.5 hours) sleepers were at greater risk for diabetes (relative risk [RR] = 1.56, 95% confidence interval [CI] = 1.02-2.39, and 1.40, 95% CI = 1.01-1.96, respectively [reference: 7 hours]). Moreover, the prevalence of any regular sleep disorder was associated with incident diabetes (RR = 1.30, 95% CI = 1.01-1.68), and with incident prediabetes (RR = 1.31, 95% CI = 1.00-1.72). Regular daytime nappers had no increased risk of incident diabetes (RR = 1.00, 95% CI = 0.70-1.41). This study shows that people with regular sleep disorders, people with short and long sleep duration, but not regular daytime nappers are at increased risk of diabetes. Furthermore, regular sleep disorders are associated with an increased risk of prediabetes. Copyright © 2016 Elsevier B.V. All rights reserved.

Reconstructing apology: David Cameron's Bloody Sunday apology in the press.

PubMed

McNeill, Andrew; Lyons, Evanthia; Pehrson, Samuel

2014-12-01

While there is an acknowledgement in apology research that political apologies are highly mediated, the process of mediation itself has lacked scrutiny. This article suggests that the idea of reconstruction helps to understand how apologies are mediated and evaluated. David Cameron's apology for Bloody Sunday is examined to see how he constructs four aspects of apology: social actors, consequences, categorization, and reasons. The reconstruction of those aspects by British, Unionist, and Nationalist press along with reconstructions made by soldiers in an online forum are considered. Data analysis was informed by thematic analysis and discourse analysis which helped to explore key aspects of reconstruction and how elements of Cameron's apology are altered in subsequent mediated forms of the apology. These mediated reconstructions of the apology allowed their authors to evaluate the apology in different ways. Thus, in this article, it is suggested that the evaluation of the apology by different groups is preceded by a reconstruction of it in accordance with rhetorical goals. This illuminates the process of mediation and helps to understand divergent responses to political apologies. © 2013 The British Psychological Society.

[The Concept of Typology in Psychiatry in the Context of Historical Contributions of Max Weber and Karl Jaspers].

Jäger, M; Becker, T; Wigand, M E

2016-08-01

Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available. © Georg Thieme Verlag KG Stuttgart · New York.

Professor Samuel David Gross (1805-1884) is considered as one of the founders of American surgery. He was a skillful surgeon who could excellently perform a lithotomy, an amputation, and a cataract surgery. He introduced many new surgical techniques and designed new surgical and medical instruments. He expertise was not limited to surgery alone; he also published studies concerning internal medicine, pathology, experimental physiology, and pharmacology. His most important treatise was his 2-volume work, A System of Surgery, Pathological, Diagnostic, Therapeutic and Operative (1861), which was a standard reference book in surgery in the United States during the second half of 19th century. Gross received many honors during his life. He was active in the operating room until his death.

Exposure to manganese (Mn) may cause movement disorders, but less is known whether the effects persist after the termination of exposure. This study investigated the association between former exposure to Mn and fine motor deficits in elderly men from an industrial area with steel production. Data on the occupational history and fine motor tests were obtained from the second follow-up of the prospective Heinz Nixdorf Recall Study (2011-2014). The study population included 1232 men (median age 68 years). Mn in blood (MnB) was determined in archived samples (2000-2003). The association between Mn exposure (working as welder or in other at-risk occupations, cumulative exposure to inhalable Mn, MnB) with various motor functions (errors in line tracing, steadiness, or aiming and tapping hits) was investigated with Poisson and logistic regression, adjusted for iron status and other covariates. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated for substantially impaired dexterity (errors >90th percentile, tapping hits <10th percentile). The median of cumulative exposure to inhalable Mn was 58 µg m-3 years in 322 men who ever worked in at-risk occupations. Although we observed a partly better motor performance of exposed workers at group level, we found fewer tapping hits in men with cumulative Mn exposure >184.8 µg m-3 years (OR 2.15, 95% CI 1.17-3.94). MnB ≥ 15 µg l-1, serum ferritin ≥ 400 µg l-1, and gamma-glutamyl transferase ≥74 U l-1 were associated with a greater number of errors in line tracing. We found evidence that exposure to inhalable Mn may carry a risk for dexterity deficits. Whether these deficits can be exclusively attributed to Mn remains to be elucidated, as airborne Mn is strongly correlated with iron in metal fumes, and high ferritin was also associated with errors in line tracing. Furthermore, hand training effects must be taken into account when testing for fine motor skills. © The Author 2017. Published by Oxford

The moral status of the embryo: an attempt at an analysis with the aid of David Hume's ethics.

This article applies the moral sentimentalism founded by David Hume to the moral status of the embryo. It will attempt to explain the paradoxical fact that in Germany abortion is common and socially accepted while preimplantation genetic diagnosis is banned with the aid of an approach based on moral sentimentalism. David Hume established the thesis that the human being is guided by the emotions and not by reason when making moral decisions. Scientific innovations often create a feeling of anxiety. Consequently, the initial moral judgment about it is negative. Due to this habit, the innovation is often accepted after a phase of indifference. This phenomenon has been observed in the case of heart transplantation, as well as for IVF. Consequently, the apparent contradiction in the varying degrees of the embryo's worthiness of protection in the womb and in the Petri dish is due to the simple fact that these are different stages of habituation. Therefore, the ethics of Hume cannot stipulate the embryo's moral status for once and for all; however, they can paradoxically raise the ongoing current debate to a more rational level through the insight that the underlying moral concepts are not based on reason alone.

Mental files theory of mind: When do children consider agents acquainted with different object identities?

Huemer, Michael; Perner, Josef; Leahy, Brian

2018-02-01

Mental files theory explains why children pass many perspective taking tasks like the false belief test around age 4 (Perner & Leahy, 2016). It also explains why older children struggle to understand that beliefs about an object depend on how one is acquainted with it (intensionality or aspectuality). If Heinz looks at an object that is both a die and an eraser, but cannot tell by looking that it is an eraser, he will not reach for it if he needs an eraser. Four- to 6-year olds find this difficult (Apperly & Robinson, 1998). We tested 129 35- to 86-month olds with a modified version of Apperly and Robinson's task. Each child faced four tasks resulting from two experimental factors, timing and mode of information. Timing: Children saw Heinz learn the die's location either before or after they learn that the die is an eraser. Mode of information: Heinz learns where the die is either perceptually or verbally. When Heinz' learning is verbal, he never perceives the die at all. We found that Apperly and Robinson's problem occurs only in the seen-after condition, where Heinz sees the die afterchildren had learnt that it was also an eraser. It vanishes when Heinz learns where the die is before children learn that it is also an eraser. The problem also vanishes when Heinz learns where the die is purely verbally (e.g., "The die is in the red box") and never sees it. This evidence lets us refine existing mental files theory, and eliminate several alternatives from the literature. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

Tandem Duplication Events in the Expansion of the Small Heat Shock Protein Gene Family in Solanum lycopersicum (cv. Heinz 1706).

In plants, fruit maturation and oxidative stress can induce small heat shock protein (sHSP) synthesis to maintain cellular homeostasis. Although the tomato reference genome was published in 2012, the actual number and functionality of sHSP genes remain unknown. Using a transcriptomic (RNA-seq) and evolutionary genomic approach, putative sHSP genes in the Solanum lycopersicum (cv. Heinz 1706) genome were investigated. A sHSP gene family of 33 members was established. Remarkably, roughly half of the members of this family can be explained by nine independent tandem duplication events that determined, evolutionarily, their functional fates. Within a mitochondrial class subfamily, only one duplicated member, Solyc08g078700, retained its ancestral chaperone function, while the others, Solyc08g078710 and Solyc08g078720, likely degenerated under neutrality and lack ancestral chaperone function. Functional conservation occurred within a cytosolic class I subfamily, whose four members, Solyc06g076570, Solyc06g076560, Solyc06g076540, and Solyc06g076520, support ∼57% of the total sHSP RNAm in the red ripe fruit. Subfunctionalization occurred within a new subfamily, whose two members, Solyc04g082720 and Solyc04g082740, show heterogeneous differential expression profiles during fruit ripening. These findings, involving the birth/death of some genes or the preferential/plastic expression of some others during fruit ripening, highlight the importance of tandem duplication events in the expansion of the sHSP gene family in the tomato genome. Despite its evolutionary diversity, the sHSP gene family in the tomato genome seems to be endowed with a core set of four homeostasis genes: Solyc05g014280, Solyc03g082420, Solyc11g020330, and Solyc06g076560, which appear to provide a baseline protection during both fruit ripening and heat shock stress in different tomato tissues.

As a modifiable lifestyle factor, diet is hypothesized to play an important role in the progression of atherosclerosis. The aim of this study was to explore associations of comprehensive dietary patterns derived by cluster analysis with degree and progression of coronary artery calcification (CAC) over five years of follow-up. In the population-based Heinz Nixdorf Recall study, 3718 participants (45-75 years; 47.6% men) without coronary heart disease completed a food frequency questionnaire at baseline. Five distinct dietary patterns were identified using cluster analysis: "Health-conscious", "Traditional German/Less alcohol", "Mediterranean-like", "Western" and "Animal fat/Alcohol" (used as reference). CAC was measured using electron-beam computed tomography at baseline and five years later. CAC after five years was predicted based on sex- and age-specific baseline percentiles. After comparing observed and predicted CAC Scores, CAC progression was classified as slow, expected, or rapid. Compared to "Animal fat/Alcohol" diet, a "Mediterranean-like" diet was associated with a relative risk (RR) for a rapid CAC progression in both sexes (men: 0.61; 95%-confidence interval [95%-CI]: 0.41; 0.90; women: 0.59; 95%-CI: 0.45; 0.78). Furthermore, reduced RRs were observed in women with a "Health-conscious" and a "Traditional German/Less alcohol" diet (0.63; 95%-CI: 0.47; 0.84, respectively 0.69; 95%-CI: 0.52; 0.90). No association was observed for a "Western" diet for both sexes. Similar results were revealed for degree of CAC. The study results support the hypothesis that a "Mediterranean-like" diet is associated with a lower CAC-progression and lower degree of CAC in men and women.

The Père David's deer is a highly inbred, but recovered, species, making it interesting to consider their adaptive molecular evolution from an immunological perspective. Prior to this study, genomic sequencing was the only method for isolating all functional MHC genes within a certain species. Here, we report a novel protocol for isolating MHC class II loci from a species, and its use to investigate the adaptive evolution of this endangered deer at the level of multi-locus haplotypes. This protocol was designated “HURRAH” based on its various steps and used to estimate the total number of MHC class II loci. We confirmed the validity of this novel protocol in the giant panda and then used it to examine the Père David's deer. Our results revealed that the Père David's deer possesses nine MHC class II loci and therefore has more functional MHC class II loci than the eight genome-sequenced mammals for which full MHC data are currently available. This could potentially account at least in part for the strong survival ability of this species in the face of severe bottlenecking. The results from the HURRAH protocol also revealed that: (1) All of the identified MHC class II loci were monomorphic at their antigen-binding regions, although DRA was dimorphic at its cytoplasmic tail; and (2) these genes constituted two asymmetric functional MHC class II multi-locus haplotypes: DRA1*01 ∼ DRB1 ∼ DRB3 ∼ DQA1 ∼ DQB2 (H1) and DRA1*02 ∼ DRB2 ∼ DRB4 ∼ DQA2 ∼ DQB1 (H2). The latter finding indicates that the current members of the deer species have lost the powerful ancestral MHC class II haplotypes of nine or more loci, and have instead fixed two relatively weak haplotypes containing five genes. As a result, the Père David's deer are currently at risk for increased susceptibility to infectious pathogens. PMID:21267075

"Describing our whole experience": the statistical philosophies of W. F. R. Weldon and Karl Pearson.

PubMed

Pence, Charles H

2011-12-01

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton's footsteps. I argue for two related theses in light of this standard interpretation, based on a reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach statistics from this "Galtonian" perspective, he is, consistent with his positivist philosophy of science, utilizing statistics to simplify the highly variable data of biology. Weldon, on the other hand, is brought to statistics by a rich empiricism and a desire to preserve the diversity of biological data. Secondly, we have here a counterexample to the claim that divergence in motivation will lead to a corresponding separation in methodology. Pearson and Weldon, despite embracing biometry for different reasons, settled on precisely the same set of statistical tools for the investigation of evolution. Copyright © 2011 Elsevier Ltd.

sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between

Writing a study of psychologist David Boder's 1946 displaced persons (DP) interview project gave me a chance to further document the substantial early response to the Holocaust. This was clearly one important piece of my study, and one that was eminently straightforward. Yet much of the research on Boder's project at the point in time that I carried it out was elliptical, partly because the primary interview materials were coming to light at an astonishing pace, partly because the archive collections were virtually untapped, and partly because of the misconception of Boder and his interview project itself.

Acute Stanford type A aortic dissection requires an extremely complex surgical strategy and presents high risk of complications. Although many different procedures were reported to treat this aortic dissection, high mortality rate and incidences of complications still exist. This study presents a 59-year-old lady with acute Stanford type A aortic dissection, which originated from the aortic root to proximal part of right external iliac artery and involved the brachiocephalic trunk, left carotid artery, celiac trunk, and left renal artery. The patient underwent one-stage hybrid surgery of David procedures, debranching, and endovascular aortic repair under ultrasound-guided aortic arch cannulation cardiopulmonary bypass (CPB). The surgery was successfully performed, and the patient showed no post-operative complication. The one-staged hybrid surgery of David procedures, debranching, and endovascular aortic repair provides novel and well-designed combined techniques for treating complex acute Stanford type A aortic dissection. Our techniques significantly lowered the risks, thereby expanding the indications of surgical intervention for acute Stanford type A aortic dissection.

The reconstitution of political theory: David Easton, behavioralism, and the long road to system.

Gunnell, John G

During the last half of the twentieth century, the concept of system was arguably the most important concept in the theoretical repertoire of the discipline of American political science. Although systems analysis was broadly employed in the behavioral sciences, David Easton's work was particularly influential in the study of politics. This is in part because he attempted to develop a distinct account of the political system that was not theoretically subservient either to general systems theory or to conceptions of the social system such as that advanced by Talcott Parsons. Although a great deal of attention has been devoted to Easton's theory, the origins and evolution of the system concept in his work have not been carefully reconstructed and analyzed. © 2013 Wiley Periodicals, Inc.

Aortic valve calcification (AVC) is considered a manifestation of atherosclerosis. In this study, we investigated whether AVC adds to cardiovascular risk prediction beyond Framingham risk factors and coronary artery calcification (CAC). A total of 3944 subjects from the population based Heinz Nixdorf Recall Study (59.3±7.7 years; 53% females) were evaluated for coronary events, stroke, and cardiovascular disease (CVD) events (including all plus CV death) over 9.1±1.9 years. CT scans were performed to quantify AVC. Cox proportional hazards regressions and Harrell's C were used to examine AVC as event predictor in addition to risk factors and CAC. During follow-up, 138 (3.5%) subjects experienced coronary events, 101 (2.6%) had a stroke, and 257 (6.5%) experienced CVD events. In subjects with AVC>0 versus AVC=0 the incidence of coronary events was 8.0% versus 3.0% (p<0.001) and the incidence of CVD events was 13.0% versus 5.7% (p<0.001). The frequency of events increased significantly with increasing AVC scores (p<0.001). After adjustment for Framingham risk factors, high AVC scores (3rd tertile) remained independently associated with coronary events (HR 2.21, 95% CI 1.28 to 3.81) and CVD events (HR 1.67, 95% CI 1.08 to 2.58). After further adjustment for CAC score, HRs were attenuated (coronary events 1.55, 95% CI 0.89 to 2.69; CVD events 1.29, 95% CI 0.83 to 2.00). When adding AVC to the model containing traditional risk factors and CAC, Harrell's C indices did not increase for coronary events (from 0.744 to 0.744) or CVD events (from 0.759 to 0.759). AVC is associated with incident coronary and CVD events independent of Framingham risk factors. However, AVC fails to improve cardiovascular event prediction over Framingham risk factors and CAC.

We developed a combined procedure for the analysis of works of art based on a portable system for fluorescence imaging integrated with analytical measurements on microsamples. The method allows us to localize and identify organic and inorganic compounds present on the surface of artworks. The fluorescence apparatus measures the temporal and spectral features of the fluorescence emission, excited by ultraviolet (UV) laser pulses. The kinetic of the emission is studied through a fluorescence lifetime imaging system, while an optical multichannel analyzer measures the fluorescence spectra of selected points. The chemical characterization of the compounds present on the artistic surfaces is then performed by means of analytical measurements on microsamples collected with the assistance of the fluorescence maps. The previous concepts have been successfully applied to study the contaminants on the surface of Michelangelo's David. The fluorescence analysis combined with Fourier transform infrared (FT-IR) measurements revealed the presence of beeswax, which permeates most of the statue surface, and calcium oxalate deposits mainly arranged in vertical patterns and related to rain washing.

B-type natriuretic peptide (BNP) as well as N-terminal-proBNP (NT-proBNP) are associated with cardiac events in the general population. Yet, data from the general population comparing both peptides for their prognostic value is lacking. Participants from the population-based Heinz-Nixdorf-Recall-study without cardiovascular diseases were included. Associations of BNP and NT-proBNP with incident cardiovascular events (incident myocardial infarction, stroke, or cardiovascular death) were assessed using Cox regression; prognostic value was addressed using Harrell's c statistic. From overall 3589 subjects (mean age: 59.3 ± 7.7 yrs, 52.5% female), 235 subjects developed a cardiovascular event during 8.9 ± 2.2 yrs of follow-up. In regression analysis both natriuretic peptides were associated with incident cardiovascular events, independent of traditional risk factors (hazard ratio (HR) per unit increase on log-scale (95% CI): NT-proBNP: 1.60 (1.39; 1.84); BNP: 1.37 (1.19; 1.58), p<0.0001 respectively). Specifically looking at subjects <60 yrs only NT-proBNP, was linked with events (HR (95% CI): 1.59 (1.19; 2.13) for NT-proBNP, p=0.0019; HR: 1.25 (0.94; 1.65) for BNP, p=0.12, after adjustment for age and gender). Similar results were observed for females (HR (95% CI) 1.65 (1.28; 2.12), p=0.0001 for NT-proBNP, and 1.24 (0.96; 1.61), p=0.10 for BNP after adjustment for age). Adding NT-proBNP/BNP to traditional risk factors increased the prognostic value, with effects being stronger for NT-proBNP (Harrell's c, 0.724 to 0.741, p=0.034) as compared to BNP (0.724 to 0.732, p=0.20). Both, NT-proBNP and BNP are associated with future cardiovascular events in the general population. However, when both are available, NT-proBNP seems to be superior due to its higher prognostic value, especially in younger subjects and females. Copyright © 2015 Elsevier Ireland Ltd.

To investigate the relationship between LV size as determined by non-contrast enhanced cardiac CT with incident cardiovascular disease in the general population free of clinical cardiovascular disease. LV axial area was quantified from non-contrast CT in axial, end-diastolic images at a mid-ventricular slice in participants from the population-based Heinz Nixdorf recall study, free of cardiovascular disease (n=3926, 59±8years, 53%female). LV size index (LVI) was defined as the quotient of LV area and body surface area. Major CV events (coronary events, stroke, CV death) were assessed during follow-up. Association of LVI with events was assessed using Cox regression analysis in unadjusted and multivariable adjusted models. During 8.0±1.5years of follow-up, 219 subjects developed a major CV event. Those with events had larger LVI at baseline (2258±352 vs. 2149±276 mm2/m2, p<0.0001). In univariate analysis, increase of LVI by 1 standard deviation was associated with 40% higher risk of events (HR(95%CI):1.41(1.26-1.59), p<0.0001). Associations remained statistically significant after adjustment for CV risk factors (1.24(1.10-1.40), p=0.0007) and when further adjusting for CAC (1.21(1.07-1.37), p=0.003). There was a trend towards stronger association for subjects with low CAC-score (CAC<100:1.41(1.16-1.71), p=0.0005, CAC≥100:1.24(1.06-1.44), p=0.006) in univariate analysis which persisted after multivariable adjustment (CAC<100: 1.41(1.14-1.73), p=0.001, CAC≥100: 1.12(0.96-1.31), p=0.16). CT-derived LV size is associated with incident major CV events independent of traditional risk factors and CAC-score in a population-based cohort and may improve the prediction of hard events especially in subjects with low CAC-scores.

Statistics on legal abortions at the Women's Clinic, Karl Marx University, Leipzig, East Germany, are reported. Between 1960-June 30, 1972, there were 3955 abortions and 53,972 births. Of these, 1368 abortions and 1831 births occurred in 1972; a similar large increase in abortions has been reported from other socialist countries. Average age of patients was 30.6 years in 1960, 27.7 years in 1972. In 1960, 83.1% of patients were married, but only 66.4% in 1972. Average hospital stay was 10.3 days in 1960, 3.7 days in 1972. Complications were seen in 32.5% of cases in 1960, and in 8.3% in 1972. Statistics for each year, 1960-1972, are given, and the implications of this information for medical practice and social policy are discussed.

Emotional intelligence as an aspect of general intelligence: what would David Wechsler say?

Kaufman, A S; Kaufman, J C

2001-09-01

R. D. Roberts, M. Zeidner, and G. Matthews (2001) have carefully examined the controversial issue of whether emotional intelligence (EI) should be classified as an intelligence and whether EI's constructs meet the same psychometric standards as general intelligence's constructs. This article casts their efforts into the framework of both historical and modern IQ-testing theory and research. It details David Wechsler's attempts to integrate EI into his tests and how his conception of a good clinician would be that of an emotionally intelligent clinician. Current theories and research on IQ also have a role in EI beyond what Roberts et al. described, including J. L. Horn's (1989) expanded model and A. R. Luria's (1966) neuropsychological research, and better criteria than the Armed Services Vocational Aptitude Battery should be used in future EI studies. The authors look forward to more research being conducted on EI, particularly in future performance-based assessments.

L. David Marquet, a decorated Navy Captain, transformed an underperforming submarine crew by empowering his subordinates to be leaders and reach their full potential. He called this intent-based leadership (IBL). What would happen if Marquet's model were implemented in Graduate Medical Education (GME)?In this letter to the editor, we summarize the potential of the IBL model in graduate medical education as opposed to the traditional leader-follower method. IBL harnesses human productivity toward the shared goals of GME, which are patient care and trainee learning. This shift in mindset could lead both teachers and trainees to focus more on the real reason that we undertake GME and change behaviors for the better. We suggest that IBL can and should be adopted in GME and propose that both patients and providers will benefit from this action.

Caspar David Friedrich (1774 - 1840) is one of the most important German Romantic painters. In his paintings, he prototypically represents the melancholy, which has been mentioned by his contemporaries and later biographers. Art scientists have also referred to his melancholy for the interpretation of his work. From a medical point of view, there are only two pathographies which remain inconclusive. Having applied diagnostic criteria for psychiatric disorders to his letters and publications, to statements of his contemporaries and to his art, we propose that he had suffered from a recurrent major depression which occurred in 1799 for the first time. At least three depressive episodes followed before he was struck by a stroke in 1835. There are epidemiological, psychodynamic and personality-typological reasons supporting our diagnostic assumption. The course of his depression corresponds to phases of reduced creativity, to the chosen techniques and motives. Finally we discuss the implications of our approach for the pathographical method in general.

2003-03-15

The efficiency of azeotropic distillation and oven evaporation techniques for trace determination of water in oils has recently been questioned by the National Institute of Standards and Technology (NIST), on the basis of measurements of the residual water found after the extraction step. The results were obtained by volumetric Karl Fischer (KF) titration in a medium containing a large excess of chloroform (> or = 65%), a proposed prerequisite to ensure complete release of water from the oil matrix. In this work, the extent of this residual water was studied by means of a direct zero-current potentiometric technique using a KF medium containing more than 80% chloroform, which is well above the concentration recommended by NIST. A procedure is described that makes it possible to correct the results for dilution errors as well as for chemical interference effects caused by the oil matrix. The corrected values were found to be in the range of 0.6-1.5 ppm, which should be compared with the 12-34 ppm (uncorrected values) reported by NIST for the same oils. From this, it is concluded that the volumetric KF method used by NIST gives results that are much too high.

KARL FRIEDRICH ZOELLNER and the historical dimension of astronomical photometry A collection of papers on the History of Photometry

NASA Astrophysics Data System (ADS)

Sterken, C.; Staubermann, K. B.

This book results from presentations and discussions of a group of astronomers and historians during a one-day workshop held at Archenhold Observatory, Berlin-Treptow, on April 4, 1997. This meeting was the first forum in a series dedicated to historical aspects of observational astrophysics in the nineteenth and early twentieth century. The basic principle of these meetings is to reflect during one or more days on the work and personality of a single individual or of a group of persons, at the same time avoiding the really dominant figures that typify the age. By focusing on key people who epitomize a way of thinking and working that has formed many of the ideas by which we do astrophysical research today, we also attempt to evoke the scientific spirit of the era under consideration. In 1858, the German physicist Karl Friedrich Zoellner introduced a new type of astronomical photometer which became a bestseller in the second half of the nineteenth century and which led him to the first German professorship in astrophysics. His type of photometer allowed most accurate photometric measurements and was used at several observatories for almost half a century. This book outlines four major themes. The first part describes the observing instruments that were used by Zoellner and his contemporaries: photometers and spectrographs that complemented his original design, but also competed with his most versatile prototype photometer. The description also includes an account of technical aspects associated with the replication of such a photometer today. The second part analyses the astrophysical data that were obtained with Zoellner's tools, and extracts information hidden in the published data --- scientific information as well as diverse aspects related to the observer himself. These nineteenth-century data are now published for the first time on a modern magnitude scale and are directly accessible in tabular form, and are thus fully applicable to archeophotometric studies

Stricken by ALS at the age of 27, David Jayne slowly lost the ability to walk, to eat, to speak, and to breathe. With the assistance of home health professionals, medical technologies, and volunteers, he has managed to maintain as full a life as possible, participating in some of his children's activities and even managing, with great effort, to attend a football game. However, when he was the subject of a newspaper article, his home health coverage was dropped because he didn't meet the federal definition of "homebound." This is the story of how he took on the political establishment single-handedly, and eventually realized a victory that has the potential of helping thousands of people in similar situations to no longer be imprisoned at home.

The Multi-Ethnic Study of Atherosclerosis (MESA) and the Heinz Nixdorf RECALL (Risk factors, Evaluation of Coronary Calcium and Lifestyle Factors) study (HNR) differed in regard to informing physicians and patients of the results of their subclinical atherosclerosis. This study investigates whether the association of the presence of coronary calcium with incident nonfatal and fatal cardiovascular events is different among these 2 large, population-based observational studies. All white subjects aged 45 to 75 years, free of baseline cardiovascular disease were included (n = 2232 in MESA; n = 3119 HNR participants). We studied the association between coronary calcium and event rates at 5 years, including hard cardiac events (myocardial infarction, cardiac death, resuscitated cardiac arrest), and separately added revascularizations and strokes (fatal and nonfatal) to determine adjusted hazard ratios. Both cohorts showed low coronary heart disease (including revascularization) rates with zero coronary calcium (1.13% and 1.16% over 5 years in MESA and HNR, respectively) and increasing significantly in both groups with Agatston score 100 to 399 (6.71% and 4.52% in MESA and HNR, respectively) and Agatston score > 400 (12.5% and 13.54% in MESA and HNR, respectively) and showing strong independent predictive values for Agatston scores of 100 to 399 and >400, despite multivariable adjustment for risk factors. Risk factor-adjusted 5-year revascularization rates were nearly identical for HNR and MESA and were generally low for both studies (1.4% [45 of 3119] for HNR and 1.9% [43 of 2232] for MESA) over 5 years. Across 2 culturally diverse populations, Agatston score >400 is a strong predictor of events. High Agatston score did not statistically result in revascularization, and knowledge of the presence of coronary calcium did not increase revascularizations.

Prins Karls Forland (PKF) is a N-S elongated island situated west of Spitsbergen in the Svalbard archipelago, High Arctic. The northern part of the island is dominated by siliciclastic metasediments regionally metamorphosed to greenshist facies assemblages during one distinct stage of tectonism. Amphibolite facies garnet-mica schists, mica schists, quartzites and carbonate-silicate rocks exhibiting evidence of at least two distinct, strong deformation episodes (including mylonitization) locally outcrop on the east coast of PKF, termed the Pinkie Unit. A ~1 km wide shear zone containing ductile to brittle structures and distinct outcrops of greenstones (metagabbros and greenschists), associated with magnetite ore, separates these two contrasting tectonic units. Ten samples of greenstones were collected on the slopes of Lauratzonfjellet and Boureefjellet for petrologic and geochemical analyses. Despite intense localized shearing, the metagabbros are undeformed and preserve coarse crystalline, magmatic texture, which is locally poikilitic. The primary magmatic assemblage consists of brown hornblende, plagioclase, biotite and opaque minerals, with accessory apatite and titanite. No relicts of pyroxenes are preserved. Formation of secondary uralite, sericite and chlorite is observed. Metamorphic assemblage consists of actinolite pseudomorhs after hornblende, epidote, and second generation biotite. Blue amphibole is observed in one sample from Boureefjellet; greenschists from Boureefjellet also contain fibrous blue amphibole, as well as garnets, actinolite, epidote and biotite. Some rocks sampled on Boureefjellet are more strongly deformed and exhibit probably two stages of metamorphism: amphibolite facies metamorphism resulting in blue amphibole-garnet assemblage followed by greenschist facies metamorphism resulting in actinolite-epidote-biotite paragenesis. Parallel and overlapping patterns on chondrite-normalized REE diagrams and spider diagrams indicate that these

At the beginning of the 20th century, two known medical historians, Karl Sudhoff and Henry Ernst Sigerist, were among the first persons, who took up thorough investigations of medical manuscripts in Leipzig. Above all, it was Mr. Sudhoff, who developed his own procedure, in order to exploit the unknown stocks. Apart from the only means available to him, the so-called Leyser-papers, written by the Leipzig librarian Hermann Leyser, at least once Sudhoff made a complete check-up of all manuscripts over the period of 22 years. On 315 sheets he took down various more or less extensive notes regarding these Codices, which are kept today as manuscript collection (Ms 01269) in the library of the university of Leipzig. Many publications were written on the basis of these readings. Sigerist was only looking through a small number of Leipzig manuscripts, as could be seen from his remarks written onto the users' cards. However, he could rely on Sudhoff's notes and look for specific manuscripts that he was interested in and review them. This was a first and very important step for the investigation of Leipzig medical manuscripts.

Radio observations of atmospheric gravity waves with Callisto

Monstein, C.

2013-12-01

On December 12th 2013 NOAA reported between 08:04 and 12:08 only radio noise at 245 MHz observed in San Vito. But some European observatories of the e-Callisto network (Germany, UK and Ireland) observed very strange reverse drifting and v-type bursts which was never recognized by the author before. Private communication with P. Zucca from TCD showed that these strange structures are due to focusing effects in the ionosphere. Interestingly it is possible to observe complex ionospheric behavior with cheap and simple radio-telescopes like Callisto. People who are interested in such kind of observations to study ionospheric gravity waves should generate observing programs for frequencies below 100 MHz, ideally with an additional up-converter for frequencies from 15 MHz - 100 MHz. Callisto again proved to be a powerful tool for solar science and radio-monitoring. Below are shown recent observations from Bir castle in Ireland, Essen in Germany and Glasgow in Scotland. For comparison I added an observation from a LOFAR node from Chibolton in UK which was provided by Richard Fallows from Astron NL. And finally a plot from Nançay radio heliograph, provided by Karl-Heinz Gansel, Dingden Amateur Radio- Astronomy Observatory DARO, Germany. Although Callisto instruments are almost identical, the spectra look completely different, depending on their geographical longitude and latitude.

Transcervical sterilization is a non-surgical method of permanent female sterilization that is widely used and critically discussed. A review of the historiography of the method reveals that instances of its coercive use are not included in the historical account. This study offers a reexamination of the work of Carl Clauberg and Hans-Joachim Lindemann, to more deeply contextualize within the framework of current usage the coercive use of transcervical sterilization during the Third Reich and in postwar Germany. This inquiry is based on postwar criminal trial records on Clauberg, and on archival documents detailing Lindemann's activities in 1979. A comparative analysis examines arguments by medical historian Karl-Heinz Roth, and identifies shared characteristics and differences between Clauberg and Lindemann, their methods and scientific connections. The results demonstrate that the technique of transcervical sterilization has an abusive potential that may be explained as a function of the person of the physician, of the scientific method itself, and of societal and political influences. The analysis supports the argument that insights from the cases of Clauberg and Lindemann are transferrable geographically and over time, and have the potential to inform current medical practice, such as transcervical sterilization with the Essure device, whose historiographic exploration remains a desideratum. © The Author 2017.

Image reconstruction in optical interferometry has gained considerable importance for astrophysical studies during the last decade. This has been mainly due to improvements in the imaging capabilities of existing interferometers and the expectation of new facilities in the coming years. However, despite the advances made so far, image synthesis in optical interferometry is still an open field of research. Since 2004, the community has organized a biennial contest to formally test the different methods and algorithms for image reconstruction. In 2016, we celebrated the 7th edition of the "Interferometric Imaging Beauty Contest". This initiative represented an open call to participate in the reconstruction of a selected set of simulated targets with a wavelength-dependent morphology as they could be observed by the 2nd generation of VLTI instruments. This contest represents a unique opportunity to benchmark, in a systematic way, the current advances and limitations in the field, as well as to discuss possible future approaches. In this contribution, we summarize: (a) the rules of the 2016 contest; (b) the different data sets used and the selection procedure; (c) the methods and results obtained by each one of the participants; and (d) the metric used to select the best reconstructed images. Finally, we named Karl-Heinz Hofmann and the group of the Max-Planck-Institut fur Radioastronomie as winners of this edition of the contest.

David Hull's generalized natural selection as an explanation for scientific change

NASA Astrophysics Data System (ADS)

Little, Michelle Yvette

2001-10-01

Philosophers of science such as Karl Popper and Thomas Kuhn have employed evolutionary idiom in describing scientific change. In Science as a Process (1988) Hull makes evolutionary theory explanatorily applicable. He modifies key evolutionary terms in order that both biological evolution and scientific change are instances of a general selection process. According to Hull, because of naturally-existing competition for credit among researchers and the professional lineages they constitute, scientists are constrained to cooperate and collaborate. This process entails two important philosophical consequences. First, it allows for a natural justification of why the sciences can provide objective empirical knowledge. Second, appreciating its strength means that a philosophical analysis of scientific change is solidly difficult features to combine. I work on strengthening two weaknesses in Hull's arguments. First, operating in his analysis is an unexplicated notion of ``information'' running parallel to the equally opaque notion of genetic information. My third chapter provides a clear account of ``genetic information'' whose usefulness extends beyond the assistance it can render Hull as a clear concept is needed in biological contexts as well. The fourth and fifth chapters submit evidence of scientific change from radio astronomy. Hull insists on empirical backing for philosophical theses but his own book stands to suffer from selection effects as it offers cases drawn from a single subspecialty in the biological sciences. I found that in the main scientists and the change they propel accords well with Hull's explanation. However, instances of major change reveal credit- and resource-sharing to a degree contrary with what Hull would expect. My conclusion is that the naturalness of competition, instantiated during the course of standardized and relatively ``normal'' scientific research, is not the norm during periods of new research and its uncertain standards of

Obituary: David Q. Wark, 1918-2002

2003-12-01

David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. He will be long remembered for his seminal contributions to the weather satellite program. A pioneer in the use of satellite sensors to provide observations of the Earth's environment for application to weather forecasting and atmospheric science, Dr. Wark was noted for his brilliant insights, dedication, and exceptional scientific achievements. He developed many of the theoretical and experimental techniques on which NOAA's current multi- billion-dollar meteorological satellite program is based. In the 1960's and early 1970's, he and his NOAA colleague Donald Hilleary were the motivating force and principal investigators for the first satellite instruments dedicated to sounding the atmosphere for temperature and water-vapor. These instruments included the Satellite Infra-Red Spectrometer (SIRS)-A and -B and the Vertical Temperature Profile Radiometer (VTPR), which were flown on NASA's Nimbus satellites and NOAA's ITOS-D satellites, respectively. With colleague Henry Fleming, he formulated the radiative transfer equation that quantifies the spectral radiances of the Earth and its atmosphere (measured at satellite altitude) and inverted that equation mathematically to infer the atmospheric temperature profile from satellite-based measurements of those radiances. A difficulty they had to overcome was that the mathematical problem is ill-posed, i.e., it admits of an infinite number of solutions. They arrived at a unique solution via an innovative application of a-priori information on the atmospheric state. This work was described in the landmark 1965 Wark and Fleming paper in the American Meteorological Society's Monthly Weather Review. From that early period until just weeks before his death, Dr. Wark continued

Exposure to air pollution activates the innate immune system and influences the adaptive immune system in experimental settings. We investigated the association of residential long-term exposure to particulate matter (PM) and NO 2 air pollution with monoclonal gammopathy of undetermined significance (MGUS) as a marker of adaptive immune system activation. We used data from the baseline (2000-2003), 5-year (2006-2008) and 10-year (2011-2015) follow-up examinations of the German Heinz Nixdorf Recall cohort study of 4814 participants (45-75years). Residential exposure to PM size fractions and NO 2 was estimated by land-use regression (ESCAPE-LUR, annual mean 2008/2009) and dispersion chemistry transport models (EURAD-CTM, 3-year mean at baseline). We used logistic regression to estimate the effects of air pollutants on incident MGUS, adjusting for age, sex, education, smoking status, physical activity, and BMI. As a non-linear approach, we looked at quartiles (2-4) of the air pollutants in comparison to quartile 1. Of the 3949 participants with complete data, 100 developed MGUS during the 10-year follow-up. In the main model, only PM coarse was associated with incident MGUS (OR per IQR (1.9μg/m 3 ): 1.32, 95% CI 1.04-1.67). We further found positive associations between PM size fractions estimated by ESCAPE-LUR and incident MGUS by quartiles of exposure (OR Q4 vs Q1: PM 2.5 2.03 (1.08-3.80); PM 10 1.97 (1.05-3.67); PM coarse 1.98 (1.09-3.60)). Our results indicate that an association between long-term exposure to PM and MGUS may exist. Further epidemiologic studies are needed to corroborate this possible link.

[The Roots of Idiographic Paleontology: Karl Alfred von Zittel's Methodology and Conception of the Fossil Record].

PubMed

Tamborini, Marco

2015-12-01

This paper examines Karl Alfred von Zittel’s practice in order to uncover the roots of so-called idiographic paleontology.The great American paleontologist Stephen Jay Gould (1941–2002) defined the discipline of idiographic paleontology as illustration and description of the morphological features of extinct species. However, this approach does not investigate macroevolutionary patterns and processes. On the contrary, the paleobiological revolution of the 1970s implemented an epistemic methodology that illustrates macrovelutionary patterns and laws by combining idiographic data with a nomothetic form of explanation. This article elucidates the features of the idiographic data as well as the acquired knowledge coupled with this approach. First of all, Heinrich G. Bronn’s (1800–1862) statistical method is analyzed. Zittel’s practice arose as a reaction against the approximate conclusions reached by Bronn’s quantitative approach. Second, the details of Zittel’s methodology are described in order to bring out its peculiarities.The microscope played a pivotal role in creating and forming Zittel’s morphological data. This analysis sheds new light on the reasons behind the so-called ideographic paleontology, thus revising Gould’s historical reconstruction, as well as on the notion of paleontological data. However, even though Zittel aimed at reaching precise and stable conclusions,his data cannot be used for elucidating evolutionary mechanisms: they are scientific in a purely descriptive sense, but completely useless for biological investigations. Finally, this paper examines how Zittel’s methodology affects the contemporary paleobiological enterprise and thereby reflects upon the notion of natural history.

Recently, epidemiological studies have found a link between air pollution (AP) and individual components of the metabolic syndrome (MetS), a condition predisposing to cardiometabolic diseases. However, very few studies have explored a possible association between air pollution and MetS. We analyzed the effects of long-term exposure to airborne particulate matter and NO 2 on prevalence and incidence of MetS. We used data of the population-based prospective Heinz Nixdorf Recall study (baseline 2000-2003) to investigate the association(s) between AP exposure and MetS prevalence at baseline (n = 4457) and MetS incidence at first follow-up visit (n = 3074; average follow-up: 5.1 years). Mean annual exposure to size-fractioned particulate matter (PM 10 , PM 2.5 , PM coarse , and PM 2.5 abs) and nitrogen dioxide (NO 2 ) was assessed using a land use regression model. MetS was defined as central obesity plus two out of four additional risk factors (i.e., elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure or elevated plasma glucose). We estimated odds ratios (ORs) of MetS prevalence and incidence per interquartile range (IQR) of exposure, adjusting for demographic and lifestyle variables. We observed a MetS prevalence of 20.7% (n = 922) and an incidence of 9.7% (n = 299). NO 2 was positively associated with MetS prevalence, with an OR increase per IQR of 1.12 (95%-CI 1.02-1.24, IQR = 6.1 μg/m 3 ). PM 10 and PM 2.5 were both borderline positively associated with MetS incidence, with ORs of 1.14 (95%-CI 0.99-1.32, IQR = 2.1 μg/m 3 ) and 1.19 (95%-CI 0.98-1.44, IQR = 1.5 μg/m 3 ) per IQR, respectively. In summary, we found a weak positive association between air pollution and MetS. The strongest and most consistent effects were observed between NO 2 and prevalent MetS. Copyright © 2018.

Socioeconomic status (SES) is an important determinant of population health. Explanatory approaches on how SES determines health have so far included numerous factors, amongst them psychosocial factors such as social relationships. However, it is unclear whether social relationships can help explain socioeconomic differences in general subjective health. Do different aspects of social relationships contribute differently to the explanation? Based on a cohort study of middle and older aged residents (45 to 75 years) from the Ruhr Area in Germany our study tries to clarify the matter. For the analyses data from the population-based prospective Heinz Nixdorf Recall (HNR) Study is used. As indicators of SES education, equivalent household income and occupational status were employed. Social relations were assessed by including structural as well as functional aspects. Structural aspects were estimated by the Social Integration Index (SII) and functional aspects were measured by availability of emotional and instrumental support. Data on general subjective health status was available for both baseline examination (2000-2003) and a 5-year follow-up (2006-2008). The sample consists of 4,146 men and women. Four logistic regression models were calculated: in the first model we controlled for age and subjective health at baseline, while in models 2 and 3, either functional or structural aspects of social relationships were introduced separately. Model 4 then included all variables. As former studies indicated different health effects of SES and social relations in men and women, analyses were conducted with the overall sample as well as for each gender alone. Prospective associations of SES and subjective health were reduced after introducing social relationships into the regression models. Percentage reductions between 2% and 30% were observed in the overall sample when all aspects of social relations were included. The percentage reductions were strongest in the lowest SES

In addition, the USGS provided water?quality and streamflow data collected as part of the National Stream Water Quality Accounting Network and the Federal?State Cooperative Program. The documentation provided herein serves not only as a reference for current and future editions of The State of the Nation?s Ecosystems but also provides critical information for future assessments of changes in contaminant occurrence in streams and ground water of the United States.

Sense and reliability. A conversation with celebrated psychologist Karl E. Weick. Interview by Diane L. Coutu.

Weick, Karl E

2003-04-01

Most of us see the organizations we operate in--our schools or companies, for instance--as monolithic and predictable, subjecting us to deadening routines and demanding dehumanizing conformity. But companies are more unpredictable and more alive than we imagine, according to Karl Weick, a psychology professor at the University of Michigan and an expert on organizational behavior. Weick says executives can learn a lot about managing the unexpected from organizations that can't afford surprises in the workplace--nuclear plants, firefighting units, or emergency rooms, for instance. In this conversation with HBR senior editor Diane Coutu, Weick examines the characteristics of these high-reliability organizations (HROs) and suggests ways that other organizations can implement their practices and philosophies. The key difference between high-reliability organizations and other companies is the mindfulness with which people in most HROs react to even very weak signs that some kind of change or danger is approaching. For instance, nuclear-plant workers Weick has studied immediately readjust dials and system commands when an automated system doesn't respond as expected. Weick contrasts this with Ford's inability to pick up on weak signs in the 1970s that there were lethal problems with the design of the Pinto gas tank. HROs are fixated on failure. They eschew plans and blueprints, looking instead for the details that might be missing. And they refuse to simplify reality, Weick says. Indeed, by cultivating broad work experiences and enlarging their repertoires, generalist executives can avoid getting paralyzed by "cosmology episodes"--events that make people feel as though the universe is no longer a rational, orderly system.

Walker, Michael J A

2015-11-15

David Triggle's scientific career began as a chemist, went through medicinal chemistry into pharmacology, and finally on to somewhat more philosophical interests in later years. It was a career marked by many contributions to all of those aspects of science. Chief amongst his many contributions, in addition to those in medicinal chemistry, was his work on the drugs known as calcium ion channel blockers or (calcium antagonists). In the calcium ion channel field he was a particularly instrumental figure in sorting out the mechanisms, actions and roles of the class of calcium channel blockers, known chemical and pharmacologically as the dihydropyridines (DHPs) in particular, as well as other calcium blockers of diverse structures. During the course of a long career, and extensive journeys into medicinal chemistry and pharmacology, he published voluminously in terms of papers, reviews, conference proceedings and books. Notably, many of his papers often had limited authorship where, as senior author it reflected his deep involvement in all aspects of the reported work. His work always helped clarify the field while his incisive reviews, together with his role in coordinating and running scientific meetings, were a great help in clarifying and organizing various fields of study. He has had a long and illustrious career, and is wellknown in the world of biomedical science; his contributions are appreciated, and well recognized everywhere. The following article attempts to chart a path through his work and contributions to medicinal chemistry, pharmacology, science, academia and students. Copyright © 2015 Elsevier Inc.

Issuing from the accomplishments of Köhler for the development of the intensive medicine in internal medicine-in 1964 he performed the first long-term respiration at the then Medical Clinic of the Karl Marx University, in 1969 he institutionalized the young subdiscipline at the clinic, in 1978 he founded the department for intensive medicine and is at work by his decisions concerning the development of young scientists, by the handbook "Intensive Medicine. Internal Medicine and Adjacent Subjects" as well as a member of the presidium of the GDR Society for Internal Medicine for the development of the internal intensive medicine-a description of the development of the department, its achievements and problems is given. The promotion of the intensive medicine by Köhler results, as we think, also from the comprehension that it has the duty to perform a function integrating the subdisciplines, which the modern internal medicine oriented to organs and systems threatens to lose, which, however, makes its self-apprehension, which the patient wishes and the teaching is demanding. From this and from the charge for a highly specialized care of patients who life-threateningly fell ill with internal diseases as well as from the duty to create a scientific forerunning results the stringent necessity of the development of the non-operative, in reality internal intensive medicine in the clinics for internal medicine of the county hospitals and university institutions as well as the greater identification of the internist with the subdiscipline in the district hospitals dealing with multidisciplinary intensive medicine.

First detection of thermal radio emission from solar-type stars with the Karl G. Jansky very large array

2014-06-20

We present the first detections of thermal radio emission from the atmospheres of solar-type stars τ Cet, η Cas A, and 40 Eri A. These stars all resemble the Sun in age and level of magnetic activity, as indicated by X-ray luminosity and chromospheric emission in Ca II H and K lines. We observed these stars with the Karl G. Jansky Very Large Array with sensitivities of a few μJy at combinations of 10.0, 15.0, and 34.5 GHz. τ Cet, η Cas A, and 40 Eri A are all detected at 34.5 GHz with signal-to-noise ratios of 6.5, 5.2, andmore » 4.5, respectively. 15.0 GHz upper limits imply a rising spectral index greater than 1.0 for τ Cet and 1.6 for η Cas A, at the 95% confidence level. The measured 34.5 GHz flux densities correspond to stellar disk-averaged brightness temperatures of roughly 10,000 K, similar to the solar brightness temperature at the same frequency. We explain this emission as optically thick thermal free-free emission from the chromosphere, with possible contributions from coronal gyroresonance emission above active regions and coronal free-free emission. These and similar quality data on other nearby solar-type stars, when combined with Atacama Large Millimeter/Submillimeter Array observations, will enable the construction of temperature profiles of their chromospheres and lower transition regions.« less

A philosophical analysis of David Orr's theory of ecological literacy: biophilia, ecojustice and moral education in school learning communities

NASA Astrophysics Data System (ADS)

Mitchell, Debra B.; Mueller, Michael P.

2011-03-01

In his writings, David Orr claims that the US is in an "ecological crisis" and that this stems from a crisis of education. He outlines a theory of ecological literacy, a mode by which we better learn the ecology of the Earth and live in a sustainable manner. While emphasizing a shock doctrine, the diagnosis of "crisis" may be correct, but it is short-lived for children and adults of the world. In this philosophical analysis of Orr's theory, it is argued that we move beyond the perspective of crisis. By extending Orr's ecological literacy with biophilia and ecojustice and by recognizing the importance of experience-in-learning, science education is envisioned to incorporate values and morals within a longer term ideology of educational reform.

We reviewed the literature on persons who have won or competed for this prize in subjects related to vision and ophthalmology. The topics were divided into vision physiology, diagnostic and therapeutic methods, disease mechanism, and miscellaneous categories. Allvar Gullstrand is the only ophthalmologist to win a Nobel Prize; he is also the only one to receive it for work in ophthalmology. Other ophthalmologists that have been nominated were Hjalmar Schiötz (tonometer), Karl Koller (topical anesthesia), and Jules Gonin (retinal detachment). Other scientists have won the prize for eye-related research: Ragnar Granit, Haldan Hartline and George Wald (chemistry and physiology of vision), and David Hubel and Torsten Wiesel (processing in the visual system). Peter Medawar is the only person born in Brazil to have won the Nobel Prize.

Between 1960 and 1982 we have autopsied 88 cases of peripartal mortality in the pathological institute of the department of medicine, Karl-Marx-University of Leipzig. According to the legal instruction in the GDR we have subdivided in direct and indirect peripartal death cases (direct and indirect relation between maternal mortality and pregnancy). We have compared both the groups (1960-1969, 1970-1982) and have found: The number of cases with indirect and direct relation between maternal mortality and pregnancy is decreased markedly in the second time period. The composition within the two time groups is very different in respect to the cause of the mortality: Between 1960 and 1969 amnioticfluid embolism, thromboembolism and air embolism, furthermore preeclampsia and their consequences as well as hemorrhages sub partu and postpartum could be found. In the second time group the most frequent causes of peripartal mortality are the different forms of embolism and preeclampsia, but then cases with a indirect relation between mortality and pregnancy with diseases of the cardiopulmonary system and of the kidneys.

The past decades have seen a tremendous development in nuclear, middle, and high energy physics. This advance was in a great part promoted by the availability of newer and more powerful instruments. Over time, these instruments grew in size as well as in sophistication and precision. Nearly all these devices had one fundamental thing in common - magnetic fields produced with currents and iron. The precision demanded by the new experiments and machines did bring the magnet technology to new frontiers requiring the utmost in the accuracy of magnetic fields. The complex properties of the iron challenged innumerable physicists inmore » the attempt to force the magnetic fields into the desired shape. Experience and analytical insight were the pillars for coping with those problems and only few mastered the skills and were in addition able to communicate their intricate knowledge. It was a fortuitous situation that the authors got to know Klaus Halbach who belonged to those few and who shared his knowledge contributing thus largely to the successful completion of two large instruments that were built at the Forschungszentrum Juelich, KFA, for nuclear and middle energy physics. In one case the efforts went to the large spectrometer named BIG KARL whose design phase started in the early 70`s. In the second case the work started in the early 80`s with the task to build a high precision 2.5 GeV proton accelerator for cooled stored and extracted beams known as COSY-Juelich.« less

COLDz: KARL G. JANSKY VERY LARGE ARRAY DISCOVERY OF A GAS-RICH GALAXY IN COSMOS

Lentati, L.; Wagg, J.; Carilli, C. L.

2015-02-10

The broad spectral bandwidth at millimeter and centimeter wavelengths provided by the recent upgrades to the Karl G. Jansky Very Large Array (VLA) has made it possible to conduct unbiased searches for molecular CO line emission at redshifts, z > 1.31. We present the discovery of a gas-rich, star-forming galaxy at z = 2.48 through the detection of CO J = 1-0 line emission in the COLDz survey and through a sensitive, Ka-band (31-39 GHz) VLA survey of a 6.5 arcmin{sup 2} region of the COSMOS field. We argue that the broad line (FWHM ∼ 570 ± 80 km s{supmore » –1}) is most likely to be CO J = 1-0 at z = 2.48, as the integrated emission is spatially coincident with an infrared-detected galaxy with a photometric redshift estimate of z {sub phot} = 3.2 ± 0.4. The CO J = 1-0 line luminosity is L{sub CO}{sup ′}=(2.2±0.3)×10{sup 10} K km s{sup –1} pc{sup 2}, suggesting a cold molecular gas mass of M {sub gas} ∼ (2-8) × 10{sup 10} M {sub ☉} depending on the assumed value of the molecular gas mass to CO luminosity ratio α{sub CO}. The estimated infrared luminosity from the (rest-frame) far-infrared spectral energy distribution (SED) is L {sub IR} = 2.5 × 10{sup 12} L {sub ☉} and the star formation rate is ∼250 M {sub ☉} yr{sup –1}, with the SED shape indicating substantial dust obscuration of the stellar light. The infrared to CO line luminosity ratio is ∼114 ± 19 L {sub ☉}/(K km s{sup –1} pc{sup 2}), similar to galaxies with similar SFRs selected at UV/optical to radio wavelengths. This discovery confirms the potential for molecular emission line surveys as a route to study populations of gas-rich galaxies in the future.« less

Obituary: David Fulmer Bender, 1913-2004

Miller, Sylvia L.

2004-12-01

David Fulmer Bender died in San Diego, California, on 13 September 2004, at the age of 91. His heart stopped suddenly while he was dancing. His pioneering work in establishing comprehensive, computer-accessible ephemerides of asteroids and comets found many applications, including the first-ever visit to an asteroid, Gaspra, by an interplanetary spacecraft. Dave was born in Reno, Nevada, on 10 February 1913, to Homer Charles Bender and Susan Bowers Bender. The family moved to Spokane, Washington, while Dave was very young. His father was a civil engineer and a graduate of MIT, who helped design bridges and dams throughout the Northwest, including the Grand Coolie Dam. Dave had a brother, Phillip (now deceased), who was one year younger. Advancing rapidly in the Spokane school system, Dave finished high school when he was 15 years old. At 16 he moved to Pasadena, California, and began his studies at the California Institute of Technology (Caltech). In addition to pursuing his course work, he was active in track and football, a tendency toward physical exercise that stayed with him for the rest of his life. It was probably during these years that Dave heard a lecture by Albert Einstein, as mentioned to colleagues many years later. Dave received a BS degree in physics in 1933, an MS in 1934, and a PhD in 1937, all from Caltech. His dissertation was entitled, "The Index of Refraction of Air in the Photographic Infrared." During his sophomore year he found his way to Pomona College in Claremont, California, where he met his future wife, Elizabeth Boyden at a social gathering. They were married in 1935. Dave's academic career spanned the years from 1937 to 1970, initially at Louisiana State University, Vanderbilt University, and then Fisk. As a life-long pacifist and conscientious objector, Dave served alternate duty during World War II. In 1946 he joined the faculty of the physics department at Whittier College in California, where he became the department chair and

During a recent parasitological survey of elasmobranchs along the coast of Argentina, two new species of eutetrarhynchid cestodes of the genera Dollfusiella Campbell et Beveridge, 1994 and Mecistobothrium Heinz et Dailey, 1974 were collected from batoids. Dollfusiella acuta sp. n. was found in four arhynchobatid skates, i.e. Sympterygia acuta Garman (type host), Sympterygia bonapartii Müller et Henle, Atlantoraja castelnaui (Miranda Ribeiro) and Atlantoraja platana (Günther), and Mecistobothrium oblongum sp. n. in the eagle ray Myliobatis goodei Garman. Dollfusiella acuta sp. n. has a tentacular armature consisting of basal rows of uncinate hooks, a distinct basal swelling with uncinate, falcate and bill hooks, and a heteroacanthous metabasal armature with heteromorphous hooks (bothrial uncinate hooks and antibothrial falcate hooks), hooks 1(1') not separated, testes in two columns and an internal seminal vesicle. The tentacular armature of M. oblongum sp. n. is characterised by basal rows of uncinate hooks, a basal swelling with uncinate and falcate hooks, a typical heteroacanthous metabasal armature with heteromorphous hooks (uncinate and falcate to spiniform), and hooks 1(1') separated and of a constant size along the tentacle. It also possesses an elongate scolex, numerous testes arranged in 5-6 irregular columns, and an internal seminal vesicle. The discovery of M. oblongum in M. goodei represents the first record of species of Mecistobothrium in the southwestern Atlantic Ocean. An amended description of Dollfusiella cortezensis (Friggens et Duszynski, 2005) is also provided to clarify details of the scolex and tentacular armature. Members of Dollfusiella in the southwestern Atlantic are specific to a single host species or to a particular host family, while M. oblongum was found in a single host species. Although globally some plerocerci of eutetrarhynchids have been found in teleosts, extensive examination of teleosts off the coast of Argentina suggests

Recent scholarship has frequently emphasized modern states' use of social science to impose universalized conceptions of rationality and order upon diverse, highly localized settings. The New Deal era experiences of William M. Leiserson and David J. Saposs, however, provide an analytical alternative. As students of the pioneering labor economist John R. Commons, Leiserson and Saposs sought to create mechanisms for state oversight of industrial labor relations that recognized local practices and arrangements. Although their approach failed to take hold within the National Labor Relations Board, localized institutional and political contingencies, and not a hegemonic modernism, account best for their frustrated aspirations in the late 1930s. © 2010 Wiley Periodicals, Inc.

The values of the per cent 24 h radioiodine uptake in the GDR are above 60--70% and speak for a low alimentary intake of iodine or renal excretion of iodine below 40 micrograms J/d. Like the struma prevalences they show a tendency increasing from north to south and characterize the whole European situation of iodine deficiency including its decrease from west to east. The mean values of radioiodine uptake of 71.7 +/- 13.2% (n = 110) in euthyroids of the district of Karl-Marx-Stadt correspond to the iodine deficiency as it occurs approximately in the districts of Erfurt, Dresden, Munich or Freiburg/B. The alimentary iodine intake of 38.4 +/- 17.2 micrograms J/d and the renal iodine excretion of 29.9 +/- 16.1 micrograms J/d, calculated from the 24 h radioiodine accumulation values of 40 euthyroid persons by means of a mathematical model developed by Oddie and co-workers were low. The latter only slightly differed (P less than 0.05) from its chemically estimated excretion of iodine in the urine: 23.1 +/- 16.9 micrograms J/g creatinine (n = 73). Between the calculated and chemically estimated excretion of iodine there was a relatively strict correlation of r = 0.68 (n = 26; P less than 0.001). The introduction of an iodine prophylaxis is regarded as an urgent necessity. Later on a new estimation of the regional "normal values" is necessary for the per cent radioiodine uptake.

The US Air Mobility Command (AMC) has tasked Pacific Northwest Laboratory (PNL) with supporting the US Department of Energy (DOE) Federal Energy Management Program`s (FEMP) mission to identify, evaluate, and assist in acquiring all cost-effective energy resource opportunities (EROs) at the David Grant Medical Center (DGMC). This report describes the methodology used to identify and evaluate the EROs at DGMC, provides a life-cycle cost (LCC) analysis for each ERO, and prioritizes any life-cycle cost-effective EROs based on their net present value (NPV), value index (VI), and savings to investment ratio (SIR or ROI). Analysis results are presented for 17 EROsmore » that involve energy use in the areas of lighting, fan and pump motors, boiler operation, infiltration, electric load peak reduction and cogeneration, electric rate structures, and natural gas supply. Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table.

The US Air Mobility Command (AMC) has tasked Pacific Northwest Laboratory (PNL) with supporting the US Department of Energy (DOE) Federal Energy Management Program's (FEMP) mission to identify, evaluate, and assist in acquiring all cost-effective energy resource opportunities (EROs) at the David Grant Medical Center (DGMC). This report describes the methodology used to identify and evaluate the EROs at DGMC, provides a life-cycle cost (LCC) analysis for each ERO, and prioritizes any life-cycle cost-effective EROs based on their net present value (NPV), value index (VI), and savings to investment ratio (SIR or ROI). Analysis results are presented for 17 EROsmore » that involve energy use in the areas of lighting, fan and pump motors, boiler operation, infiltration, electric load peak reduction and cogeneration, electric rate structures, and natural gas supply. Typical current energy consumption is approximately 22,900 MWh of electricity (78,300 MBtu), 87,600 kcf of natural gas (90,300 MBtu), and 8,300 gal of fuel oil (1,200 MBtu). A summary of the savings potential by energy-use category of all independent cost-effective EROs is shown in a table. This table includes the first cost, yearly energy consumption savings, and NPV for each energy-use category. The net dollar savings and NPV values as derived by the life-cycle cost analysis are based on the 1992 federal discount rate of 4.6%.

Are we ready for sexual reorientation therapy in the U.S. military? A response to David W. Lutz.

PubMed

Hierholzer, Robert

2004-01-01

In his paper "The Catholic Church, the American Military, and Homosexual Reorientation Therapy," David W. Lutz ultimately concludes that it is "appropriate, and highly ethical" for the American military to offer reorientation therapy to help homosexuals overcome "the vice of sodomy." The major thrust of his paper, however, is to call for abandonment of the "Don't Ask/Don't Tell" policy currently in place in the military. Lutz's paper covers much ground, and this review begins by examining whether such a wide view is necessary for the ultimate conclusions. It goes on to ask whether Lutz has omitted to mention important considerations bearing on this issue, and whether Lutz's call for the introduction of reorientation therapy is a serious call or a symbolic response to homosexual activities. Lutz fails to address essential issues such as the actual experiences of other nations having homosexuals in the military, and issues regarding what constitutes "reorientation therapy," the latter leading to questions about how such a therapy would actually be implemented.

Biomedical conflicts of interest: a defence of the sequestration thesis-learning from the cases of Nancy Olivieri and David Healy.

PubMed

Schafer, A

2004-02-01

No discussion of academic freedom, research integrity, and patient safety could begin with a more disquieting pair of case studies than those of Nancy Olivieri and David Healy. The cumulative impact of the Olivieri and Healy affairs has caused serious self examination within the biomedical research community. The first part of the essay analyses these recent academic scandals. The two case studies are then placed in their historical context-that context being the transformation of the norms of science through increasingly close ties between research universities and the corporate world. After a literature survey of the ways in which corporate sponsorship has biased the results of clinical drug trials, two different strategies to mitigate this problem are identified and assessed: a regulatory approach, which focuses on managing risks associated with industry funding of university research, and a more radical approach, the sequestration thesis, which counsels the outright elimination of corporate sponsorship. The reformist approach is criticised and the radical approach defended.

Updates of the KArLE Experiment: New Libs Calibration Under High Vacuum for the Quantification of Potassium in Basalt for In Situ Geochronology

In planetary exploration, in situ absolute geochronology is one of the main important measurements that needs to be accomplished. Until now, on Mars, the age of the surface is only determined by crater density counting, which gives relative ages. These ages can have a lot of uncertainty as they depend on many parameters. More than that, the curves must be ties to absolute ages. Thus far, only the lost lander Beagle 2 was designed to conduct absolute geochronology measurements, though some recent attempts using MSL Curiosity show that this investigation is feasible and should be strongly encouraged for future flight. Experimental: The Potassium (K)-Argon Laser Experiment (KArLE) is being developed at MSFC through the NASA Planetary Instrument Definition and Development Program (PIDDP). The goal of this experiment is to provide in situ geochronology based on the K-Ar method. A laser ablates a rock under high vacuum, creating a plasma which is sensed by an optical spectrometer to do Laser Induced Breakdown Spectroscopy (LIBS). The ablated material frees gases, including radiogenic 40Ar,which is measured by a mass spectrometer (MS). As the potassium is a content and the 40Ar is a quantity, the ablated mass needed in order to relate them. The mass is given by the product of the ablated volume by the density of this material. So we determine the mineralogy of the ablated material with the LIBS spectra and images and calculate its density. The volume of the pit is measured by using microscopy. LIBS measurement of K under high vacuum: Three independant projects [1, 2, 3] including KArLE, are developing geochronological instruments based on this LA-LIBS-MS method. Despite several differences in their setup, all of them have validated the methods with analyses and ages. However, they all described difficulties with the LIBS measurements of K [3,4]. At ambient pressure, the quantification of K by LIBS on geological materials can be accurate [5]. However the protocol of the LA

Over the period 1995-2012, David Triggle was a frequent visitor to the China Pharmaceutical University in Nanjing, China making many important contributions that enhanced the activities of the Research Division of Pharmacology at the University. In addition to providing collegial advice and facilitating interactions with the international pharmacological community, Professor Triggle's international reputation as a thought leader in the field of ion channel research and drug discovery provided important insights into the potential pathophysiological and therapeutic effects of targeting ion channels. This included the L-type calcium channel and the outward delayed rectified potassium currents of rapid (IKr) and slow (IKs) components in the myocardium. The Nanjing research team had been particularly interested in ion channel dysfunction in the context of cardiac arrhythmias, remodeling and drug discovery. With Professor Triggle's assistance, the relationship between an increase in ICa.L and other biological events including an enhancement of IKr and IKr currents, NADPH oxidase and endothelin receptor activation, down regulation of calcium modulating protein FKBP12.6, sarco/endoplasmic reticulum Ca(2+)ATPse (SERCA2A) and calsequens 2 (CASQ2), calcium leak at the diastole and endoplasmic reticulum stress, were evaluated and are discussed. Additionally, the organization of several international symposia was greatly enhanced by input from Professor Triggle as were the published research manuscripts in international pharmacology journals. During his association with the China Pharmaceutical University, Professor Triggle aided in enhancing the scientific standing of the Pharmacology department and was a highly effective ambassador for international research cooperation.

The Liberating Role of Astronomy in an Old Farmer's Almanac: David Rittenhouse's "Useful Knowledge" and a Benjamin Banneker Almanac for 1792

NASA Astrophysics Data System (ADS)

Walker, Theodore, Jr.

2012-06-01

Traditionally, astronomy met theology and political ethics in almanacs. As presented in early New England almanacs of the farmer's type, astronomy was deity-affirming and liberty-oriented. The old English label for astronomy that affirms theology was "Astro-theology" (William Derham, 1715). The New England rendering of astro-theology was so strongly oriented towards liberty that it can now be labeled astro-liberation theology. This 21st century label is appropriate because 18th century New England printers and astronomers used astronomy to demonstrate the glory of the Creator (astro-theology) and to encourage liberation from colonialism and slavery (astro-liberation theology). A philosophy of astronomy as "useful knowledge' expressed by David Rittenhouse in 1775 - and implicit in a Benjamin Banneker almanac for 1792 - included liberty-oriented visions of planet Earth as seen from outer space, and liberty-oriented visions of intelligent life on other planets orbiting other stars.

Left atrial (LA) size is associated with cardiovascular mortality and morbidity. Once cardiac computed tomography (CT) is performed, information on LA size is readily available without additional contrast media or radiation exposure. To determine the association of CT-derived LA area and body surface area-adjusted (BSA) LA index with cardiovascular risk factors and describe age- and gender-specific normative values in a general population cohort. This study included 3945 participants (mean age, 59 ± 8 years; 53% women) from the community-based Heinz Nixdorf Recall Study. LA area in an axial image at the level of the mitral valve was quantified from non-contrast-enhanced electron-beam CT by manual delineations of the boundaries of the LA with exclusion of subjects with prevalent cardiovascular disease. Definition of normative values was performed in subjects without predictors of LA enlargement. LA quantification was feasible in all subjects. Men had larger LA size (1856 mm(2) vs. 1677 mm(2), P < 0.0001), while after adjustment for BSA, this effect was inverted (910 mm(2)/m(2) vs. 933 mm(2)/m(2) for men and women, P < 0.0001). Determinants of body size were major predictors of LA size (body mass index [BMI]: R(2) = 0.195, BSA: R(2 )= 0.216, both P < 0.0001). Blood pressure was associated with LA size (parameter-estimate [95% confidence interval] = 51.0 (4.9-57.1) mm(2)/10 mmHg for systolic, 31.4 (25.4-37.4) mm(2)/5 mmHg for diastolic blood pressure, 214.6 (186.9-242.3) mm(2) for antihypertensive medication, P < 0.0001 for all). Cholesterol levels, lipid-lowering therapy, and diabetes were associated with LA in univariable analysis, however, correlations were low (r(2 )≤ 0.026). Current smoking was associated with reduced LA size (-115.9 [-149.0 - -82.8] mm(2), P < 0.0001). In multivariable regression, BMI, blood pressure, antihypertensive medication, and smoking remained associated with LA size (P < 0.005). Non-contrast-enhanced cardiac CT enables LA

Background The association between non-steroidal anti-inflammatory drugs (NSAIDs) and the incidence of valvular and arterial calcification is not well established despite known associations between these drugs and cardiovascular events. Objective To compare the association between the baseline use of aspirin with other NSAID class medications with the incidence and prevalence of aortic valve calcification (AVC) and coronary artery calcium (CAC). Methods The relationship of NSAID use to AVC and CAC detected by computed tomography was assessed in 6,814 participants within the Multi-Ethnic Study of Atherosclerosis (MESA) using regression modeling. Results were adjusted for age, sex, ethnicity, study site, anti-hypertensive medication use, education, income, health insurance status, diabetes, smoking, exercise, body mass index, blood pressure, serum lipids, inflammatory markers, fasting glucose, statin medication use, and a simple diet score. Medication use was assessed by medication inventory at baseline which includes the use of non-prescription NSAIDs. MESA collects information on both incident and prevalent calcification. The 4,814 participants of the Heinz Nixdorf Recall (HNR) Study, a German prospective cohort study with similar measures of calcification, were included in this analysis to enable replication. Results Mean age of the MESA participants was 62 years (51% female). After adjustment for possible confounding factors, a possible association between aspirin use and incident AVC (Relative Risk(RR): 1.60; 95%Confidence Interval (CI): 1.19–2.15) did not replicate in the HNR cohort (RR: 1.06; 95%CI: 0.87–1.28). There was no significant association between aspirin use and incident CAC in the MESA cohort (RR 1.08; 95%CI: 0.91–1.29) or in the HNR cohort (RR 1.24; 95%CI: 0.87–1.77). Non-aspirin NSAID use was not associated with either AVC or CAC in either cohort. There were no associations between regular cardiac dose aspirin and incident calcification in

August Karl Gustav Bier introduced two important techniques in regional block: intravenous regional block and subarachnoid block, widely used nowadays. Since the first one celebrates its 100th anniversary and the second its 110th anniversary, it is only fair that we pay homage to this extraordinary physician who created them. This report describes his family, school, academic course, and medical residency data, professional and university activities, personality, retirement, and death of A. K. G. Bier. It describes his countless contributions to Medicine and to Anesthesiology in particular. It discusses his research on intravenous regional block, many of them still valid nowadays or not completely explained. It mentions his initial studies and the controversies on his role in the creation of spinal block. It tells the experiences he had in both World Wars. It also mentions the great contributions of Bier to culture, sports, physical education and, especially, to ecology when he created the famous Sauen Forest. Finally, the well deserved honors he received in his home country and in other countries are mentioned. A. K. G. Bier created and introduced two notable and still current methods of regional blocks in Anesthesiology and was a great defender of the preservation of the environment. Therefore, since this year we celebrate the 100th anniversary of intravenous regional block, his biography deserves to be told as a tribute to this important German physician.

Slow reception and under-citedness in climate change research: A case study of Charles David Keeling, discoverer of the risk of global warming.

The Keeling curve has become a chemical landmark, whereas the papers by Charles David Keeling about the underlying carbon dioxide measurements are not cited as often as can be expected against the backdrop of his final approval. In this bibliometric study, we analyze Keeling's papers as a case study for under-citedness of climate change publications. Three possible reasons for the under-citedness of Keeling's papers are discussed: (1) The discourse on global cooling at the starting time of Keeling's measurement program, (2) the underestimation of what is often seen as "routine science", and (3) the amount of implicit/informal citations at the expense of explicit/formal (reference-based) citations. Those reasons may have contributed more or less to the slow reception and the under-citedness of Keeling's seminal works.

Several biomarkers including B-type natriuretic peptide (BNP) have been suggested to improve prediction of coronary events and all-cause mortality. Moreover, coronary artery calcium (CAC) as marker of subclinical atherosclerosis is a strong predictor for cardiovascular mortality and morbidity. We aimed to evaluate the predictive ability of BNP and CAC for all-cause mortality and coronary events above traditional cardiovascular risk factors (TRF) in the general population. We followed 3782 participants of the population-based Heinz Nixdorf Recall cohort study without coronary artery disease at baseline for 7.3 ± 1.3 years. Associations of BNP and CAC with incident coronary events and all-cause mortality were assessed using Cox regression, Harrell's c, and time-dependent integrated discrimination improvement (IDI(t), increase in explained variance). Subjects with high BNP levels had increased frequency of coronary events and death (coronary events/mortality: 14.1/28.2% for BNP ≥100 pg/ml vs. 2.7/5.5% for BNP < 100 pg/ml, respectively). Subjects with a BNP ≥100 pg/ml had increased incidence of hard endpoints sustaining adjustment for CAC and TRF (for coronary events: hazard ratio (HR) (95% confidence interval (CI)) 3.41(1.78-6.53); for all-cause mortality: HR 3.35(2.15-5.23)). Adding BNP to TRF and CAC increased measures of predictive ability: coronary events (Harrell's c, for coronary events, 0.775-0.784, p = 0.09; for all-cause mortality 0.733-0.740, p = 0.04; and IDI(t) (95% CI), for coronary events: 2.79% (0.33-5.65%) and for all-cause mortality 1.78% (0.73-3.10%). Elevated levels of BNP are associated with excess incident coronary events and all-cause mortality rates, with BNP and CAC significantly and complementary improving prediction of risk in the general population above TRF. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Nature in economic theories: Hans Immler traces recognition of the environment - and its neglect - in various classics

Labor and capital are usually considered as the primary factors of production, the costs of which are of utmost importance. In contrast, nature (including all natural resources), as the essential third factor, is disregarded. She is generally assumed to be always available, self-regenerating, and to be exploited without long-term costs. In other words, she is more or less viewed as a constant. Hans Immler's new treatise represents an important contribution in that he emphasized the role and function of the natural environment, and its neglect, in the formulation of theories of value and their long-term consequences on contemporary economic theoriesmore » and on the person and society. This essay traces Immler's evaluation with extensive quotations - especially with regard to Physiocracy and the classical economists - of nature's role and function, or their neglect, in the formulation of theories of value through the writings of Aristotle, St. Thomas Aquinas, William Petty, John Locke, Adam Smith, David Ricardo, Karl Marx, and others, - all dealt with in Part 1 of his book - and Francois Quesnay and the Physiocrats - the topic of Part 2.« less

The Belfast-born David Walker was the 19-year-old surgeon and naturalist on the epic Fox Arctic Expedition (1857-59) that established the fate of Sir John Franklin's unsuccessful (1845) search for the North-West Passage. On return the crew were fêted as heroes and decorated, and shared in a £5000 government bounty: Walker was also received by the Queen and (in Ireland) by the Lord Lieutenant, was honoured by the principal British and Irish natural history societies and his portrait was exhibited in the National Portrait Gallery, London. This paper describes his adventurous life, including the Fox Expedition, which from 1862 was spent abroad and included time in the Cariboo gold fields, service in the United States Army, practice in a notorious Californian frontier town and, in later life, the comparative quiet of general and occupational medical practice in Portland, Oregon. Once a household name, his death went unrecorded in the British and Irish medical and lay press.

‘The Solution to his Own Enigma’: Connecting the Life of Montague David Eder (1865–1936), Socialist, Psychoanalyst, Zionist and Modern Saint1

PubMed Central

THOMSON, MATHEW

2011-01-01

This article examines the career of pioneer British psychoanalyst David Eder (1865–1936). Credited by Freud as the first practising psychoanalyst in England, active in early British socialism and then a significant figure in Zionism in post-war Palestine, and in between an adventurer in South America, a pioneer in the field of school medicine, and a writer on shell-shock, Eder is a strangely neglected figure in existing historiography. The connections between his interest in medicine, psychoanalysis, socialism and Zionism are also explored. In doing so, this article contributes to our developing understanding of the psychoanalytic culture of early twentieth-century Britain, pointing to its shifting relationship to broader ideology and the practical social and political challenges of the period. The article also reflects on the challenges for both Eder’s contemporaries and his biographers in making sense of such a life. PMID:23752865

Scores from motor performance tests were compared using subjects with taped and untaped ankles. Previous studies have shown that taped ankle support may be detrimental in vertical and standing broad jumping performance. Conflicting data have been published on the effects of commercial ankle braces on various motor tasks. The performances of 18 elite soccer players in selected tests of speed, balance, agility, and vertical jumping were compared under conditions of untaped, nonelastic adhesive taped, Swede-O-braced, New Cross-braced, and McDavid-braced ankles. Vertical jump performance was significantly reduced when subjects wore New Cross braces. There were no significant differences in tests of speed, balance, and agility among any of the support conditions. Until now, nonelastic adhesive tape has been the preferred method of prophylactic ankle support. I conclude that certain commercial ankle braces may be used as a support alternative during selected activities. ImagesFig 1. PMID:16558170

Increased left ventricular (LV) size is associated with cardiovascular mortality and morbidity. Once non-contrast cardiac computed tomography (CT) is performed for other purposes, information of LV size is readily available. To determine the association of gated CT-derived LV size with cardiovascular risk factors and coronary artery calcification (CAC) and to describe age- and gender-specific normative values in a general population cohort. LV area was quantified from non-contrast-enhanced CT in axial, end-diastolic images at a mid-ventricular slice in participants of the population-based Heinz Nixdorf Recall Study, free of known cardiovascular disease. LV index (LVI) was calculated by the quotient of LV area and body surface area (BSA). Crude and adjusted regression analyses were used to determine the association of LVI with risk factors and CAC. Overall, 3926 subjects (age 59 ± 8 years, 53% women) were included in this analysis. From quantification in end-diastolic phase, men had larger LV index (2232 ± 296 mm(2)/m(2) vs. 2088 ± 251 mm(2)/m(2), both P < 0.0001). LVI was strongly correlated systolic blood pressure (men, PE [95% CI]: 22.8 [15.5-30.2] mm(2)/10 mmHg; women, 23.4 [18.1-28.6]), and antihypertensive medication (men, 45.2 [14.7-75.8] mm(2); women: 46.5 [22.7-70.2], all P < 0.005). Cholesterol levels were associated with LVI in univariate analysis, however, correlations were low (R(2) ≤ 0.04). In multivariable regression, blood pressure, antihypertensive medication and cholesterol levels, remained associated with LVI (P < 0.05). LVI was linked with CAC in unadjusted (men, increase of CAC + 1 by 13.0% [1.4-25.8] with increased LVI by 1 standard deviation of LVI, P = 0.03; women, 20.7% [10.0-32.3], P < 0.0001) and risk factor adjusted models (men, 14.6% [3.7-26.6], P = 0.007); women, 17.4% [7.8-27.8], P = 0.0002). Non-contrast cardiac CT derived LV index is associated with body size and hypertension. LVI is weakly linked with CAC-score. Further studies

Several studies have demonstrated the tremendous potential of using coronary artery calcium (CAC) in addition to traditional risk factors for coronary heart disease (CHD) risk prediction. However, to date, no risk score incorporating CAC has been developed. The goal of this study was to derive and validate a novel risk score to estimate 10-year CHD risk using CAC and traditional risk factors. Algorithm development was conducted in the MESA (Multi-Ethnic Study of Atherosclerosis), a prospective community-based cohort study of 6,814 participants age 45 to 84 years, who were free of clinical heart disease at baseline and followed for 10 years. MESA is sex balanced and included 39% non-Hispanic whites, 12% Chinese Americans, 28% African Americans, and 22% Hispanic Americans. External validation was conducted in the HNR (Heinz Nixdorf Recall Study) and the DHS (Dallas Heart Study). Inclusion of CAC in the MESA risk score offered significant improvements in risk prediction (C-statistic 0.80 vs. 0.75; p < 0.0001). External validation in both the HNR and DHS studies provided evidence of very good discrimination and calibration. Harrell's C-statistic was 0.779 in HNR and 0.816 in DHS. Additionally, the difference in estimated 10-year risk between events and nonevents was approximately 8% to 9%, indicating excellent discrimination. Mean calibration, or calibration-in-the-large, was excellent for both studies, with average predicted 10-year risk within one-half of a percent of the observed event rate. An accurate estimate of 10-year CHD risk can be obtained using traditional risk factors and CAC. The MESA risk score, which is available online on the MESA web site for easy use, can be used to aid clinicians when communicating risk to patients and when determining risk-based treatment strategies.

The area west of Prins Karls Forland (PKF, West Spitsbergen) in the Arctic Ocean, restricted to 90 m water depth, is known for a large amount of shallow active gas flares. Gas flares are streams of bubbles that contain mostly methane, which is a potent greenhouse gas. The important questions for many areas with discovered gas flares are: Does this gas reach the atmosphere? What controls the vertical and horizontal distribution of dissolved methane away from the source on the seafloor? Is all dissolved methane detected above gas flares released from those flares or does it partially originate from other areas (eg. Storfjorden, or area of deeper flares on the PKF slope)? The present study is based on two repeated oceanographic surveys conducted in the summers of 2014 and 2015. During the surveys, we sampled 64 CTD stations in a grid above a 30 x 15 km area with active methane flares. Vertical profiles of temperature (T) and salinity (S), as well as TS diagrams indicate very different oceanographic settings during the two surveys. Warm and saline Atlantic waters originating from the West Spitsbergen Current prevailed during the 2014 campaign. In 2015, in contrast, waters were distinctly less saline and cooler. These waters originate from the East-Spitsbergen current that flows northwards over the shelf from the Barents Sea around the southern tip of Spitsbergen. The water mass was furthermore influenced by local sources from the fjords. In both years, we observed strong vertical gradients in the distribution of dissolved methane in the water column above gas flares, with only 4% methane concentrations at the sea surface when compared to bottom waters. However, the circulation of the dominant water masses mainly controlled the horizontal distribution of methane in the water column in the specific year. We discuss oceanographic processes and mechanisms responsible for methane transport and transformation in the study area. This study is funded by CAGE (Centre for Arctic
