  5. Christoph Scheiner's eye studies.

    PubMed

    Daxecker, F

    1992-01-01

    Christoph Scheiner was born in 1573 or 1575. In 1595 he entered into the Order of the Jesuits; he died in 1650. In 1619 his book Oculus, dealing with the optics of the eye, appeared in Innsbruck. The invention of the telescope was of utmost importance for progress in astronomical and physical research. Scheiner himself built telescopes and discovered the sunspots. As a result, an unpleasant priority dispute with Galilei ensued. From 1624 onwards, Scheiner was in Rome, where his main work Rosa Ursina was published in 1630. A part of this book deals with the physiological optics of the eye as well. Some of his discoveries and experiments are taken from these two books: determination of the radius of curvature of the cornea, discovery of the nasal exit of the optic nerve, increase in the radius of curvature of the lens in case of accommodation, Scheiner's procedure (double images with ametropia), refractive indices of various parts of the eye, Scheiner's experiment. Without any doubt, Christoph Scheiner belongs to the foremost scientists of the first half of the 17th century. PMID:1473465

  6. Tobias Mayer--experiments on visual acuity (1755).

    PubMed

    Scheerer, E

    1987-01-01

    The pioneering experimental work of Tobias Mayer (1723-1762) on visual acuity, published in 1755 in Latin, is presented in English translation. Mayer distinguished between two kinds of visual acuity, the one (30 arc sec) for single objects seen against a uniform background, the other (1 arc min) for more complex objects such as gratings, grids, or checkerboards. Strong illumination did not improve visual acuity. For targets seen in the light of a candle, the visual angle needed for resolution was inversely proportional to the cube root of the distance of the candle and therefore to the sixth root of 'brightness'. The historical significance of Mayer's work on visual acuity is briefly outlined. PMID:3154942

  18. Christoph Rothmann's compendium of astronomy of 1589. (German Title: Christoph Rothmanns Handbuch der Astronomie von 1589)

    NASA Astrophysics Data System (ADS)

    Granada, Miguel A.; Hamel, Jürgen; von Mackensen, Ludolf

    Around 1560, landgrave William IV. founded on his Cassel castle the first permanent observatory of modern times in Europe, and started to occupy himself with systematic sky observations. From the beginning, the main interest was focussed on the fixed stars, since William had recognized that exact position determinations were a prerequisite for further progress in astronomy. The observatory personnel was enlarged, in 1579, by the mathematician, clock-maker and instrument-maker Jost Bürgi, and in 1584 by the practical astronomer Christoph Rothmann. Since that time, intense work was carried out by creating a catalogue of fixed stars, based on own observations, which was completed in 1589. The accuracy of its stellar positions had not been reached in the past, and even superseded that of the almost contemporary catalogue by Tycho Brahe. Research in theoretical astronomy and cosmology at the landgrave's court in Cassel was also revolutionary: the acceptance of the heliocentric world system, investigations on refraction, the dismissal of the concept of solid planetary spheres and even that of a world ether, the nature of cometary tails, etc. Christoph Rothmann's work, edited here for the first time on the basis of the original manuscript, had been drafted as a commentary or introduction to his catalogue of fixed stars. He describes the construction and use of astronomical instruments, he unfolds his concepts of the system of the world on a heliocentric basis without solid planetary spheres to which he was lead by his research on refraction, he discusses the relation between astronomy and theology, and describes his revolutionary work on the Cassel star catalogue. This work constitutes a compendium of theoretical and practical astronomy of the late 16th century whose major scientific importance lies in the fact that it achieves scientific excellence in its time both because of the multitude of topics and because of the high level of discussion.

    Christopher Grienberger was born on July 2, 1561 in Hall in Tyrol, Austria. In 1580 he joined the Society of Jesus (Jesuits). Grienberger studied in Prague and Vienna and succeeded his tutor, Christopher Clavius, as a professor of mathematics at the Roman College. Grienberger gave lectures in astronomy in order to prepare fellow Jesuits for their missionary work in China and constructed the equatorial set-up of the telescope. Among his works is a list of fixed stars, and he even worked in the science of optics. Grienberger sympathized with Galileo's theory of motion but was told to defend the Aristotelian view by the Father General of the Jesuits, Claudio Aquaviva. Grienberger died on March 11, 1636, and is buried in Rome.

    Daxecker, Franz; Schaffenrath, Florian

    An obituary of the astronomer and Jesuit Christoph Scheiner (1573-1650) was discovered in Cracow in the year 2001. This discovery makes it now possible to fix Scheiner's year of birth to 1573. Scheiner had a controversy with Galileo Galilei about the priority of the discovery of sunspots. Scheiner remained a supporter of the geocentric system until his death in 1650. The obituary gives new insights into Scheiner's personality and the last years of his life.

    Daxecker, Franz

    Christoph Scheiner described - as Galileo, Kepler, Foscarini - the sunspots, the phases of Venus, the moons of Jupiter, and the surface of the Moon, and he found reasons for a fluid sky. In 1614 he was declared by Father General Claudio Aquaviva SJ to be a follower of the new doctrine. He was asked to return to the old doctrine. Scheiner obeyed. He did not mention the new doctrine in his following work. However, indications in letters of his contemporaries suggest that be still secretly believed in Copernicus's ideas.

  8. [Christopher Columbus flu. A hypothesis for an ecological catastrophe].

    PubMed

    Muñoz-Sanz, Agustín

    2006-05-01

    When Christopher Columbus and his men embarked on the second Colombian expedition to the New World (1493), the crew suffered from fever, respiratory symptoms and malaise. It is generally accepted that the disease was influenza. Pigs, horses and hens acquired in Gomera (Canary Islands) traveled in the same ship. The pigs may well have been the origin of the flu and the intermediary hosts for genetic recombination of other viral subtypes. The Caribbean archipelago had a large population of birds, the natural reservoir of the avian influenza virus. In this ecological scenario there was a concurrence of several biological elements that had never before coexisted in the New World: pigs, horses, the influenza virus and humans. We propose that birds are likely to have played an important role in the epidemiology of the flu occurring on the second Colombian trip, which caused a fatal demographic catastrophe, with an estimated mortality of 90% among the natives.

    2012-09-01

    We recount the life and career of Richard Christopher Carrington (1826 - 1875) and explore his pivotal relationship with Astronomer Royal George Biddell Airy. Carrington was the pre-eminent solar astronomer of the 19th century. During a ten year span, he determined the position of the Sun's rotation axis and made the following discoveries: i) the latitude variation of sunspots over the solar cycle, ii) the Sun's differential rotation, and iii) the first solar flare (with Hodgson). Due to the combined effects of family responsibilities, failure to secure a funded position in astronomy (reflecting Airy's influence), and ill health, Carrington's productive period ended when he was at the peak of his powers.

  2. [The professor and his student. The correspondence between Lorenz Heister and Christoph Jacob Trew].

    PubMed

    Ruisinger, Marion Maria; Schnalke, Thomas

    2004-01-01

    Letters were the central medium of communication in the medical scientific community of the 18th century. Professional as well as personal relationships were established among the various correspondents. These relationships constituted the smallest units of communication which contributed to the regional and international scientific network of the Republic of Letters. A correspondence that grew out of a trusted teacher-student relationship could gain an especially intense character both intellectually and personally. This contribution offers an analysis of an example of just such a correspondence. Lorenz Heister (1683--1758), medical professor at the universities of Altdorf and Helmstedt, and his disciple, Christoph Jacob Trew (1695--1769), who became a renowned physician and natural scientist in Nuremberg, communicated in letters to one another over a span of almost forty years. Their correspondence started as a rather asymmetrical dialogue. Over time, however, Heister and Trew came to meet as equals in almost every field of their competence. Their letters reveal a broad spectrum of scientific, organisational, professional, medical and personal issues which formed the basis of a stable and lasting learned correspondence in the age of Enlightenment.

  3. The main work of astronomer Christoph Scheiner SJ "Rosa Ursina sive Sol" - a summary.

    NASA Astrophysics Data System (ADS)

    Daxecker, F.

    1996-10-01

    Christoph Scheiner was born on 25 July 1573 or 1575 in Markt Wald near Mindelheim in the Bavarian part of Swabia. He died on 18 July 1650. In Rome he wrote his main work Rosa Ursina sive Sol and had it printed with the help of a patron, Duke Paulus Jordanus II of Bracciano. The ducal family bore a rose, likened to the Sun in Scheiner's book, on its coat of arms. Rosa Ursina is divided into four volumes. In volume I Scheiner tackles the issue of who was first to discover the sunspots; he also proves that Galilei made errors of observation. Volume II shows illustrations of telescopes, projection methods and the helioscope and compares the optics of a telescope with that of the human eye. In volume III, observations on sunspots are illustrated by 70 copper engravings by David Widemann. Volume IV consists of two parts. The first part again deals with the phenomena of the Sun, such as sunspots and prominences, its period of revolution of 27 days, and the tilt of its axis; the second part is a collection of passages and quotations from the Scriptures, from Church Fathers and philosophers, all designed to prove that Scheiner's interpretation of the geocentric system conformed to Catholic doctrine.

  5. ‘By Merit Raised to That Bad Eminence’: Christopher Merrett, Artisanal Knowledge, and Professional Reform in Restoration London

    PubMed Central

    Mauck, Aaron

    2012-01-01

    This article examines the career and reform agenda of Christopher Merrett as a means of evaluating the changing conditions of medical knowledge production in late seventeenth-century London. This period was characterised by increasing competition between medical practitioners, resulting from the growing consumer demand for medical commodities and services, the reduced ability of elite physicians to control medical practice, and the appearance of alternative methods of producing medical knowledge – particularly experimental methods. This competition resulted in heated exchanges between physicians, apothecaries, and virtuosi, in which Merrett played an active part. As a prominent member of both the Royal Society and the Royal College of Physicians, Merrett sought to mediate between the two institutions by introducing professional reforms designed to alleviate competition and improve medical knowledge.These reforms entailed sweeping changes to medical regulation and education that integrated the traditional reliance on Galenic principles with knowledge derived from experiment and artisanal practices. The emphasis Merrett placed on the trades suggests the important role artisanal knowledge played in his efforts to reorganise medicine and improve knowledge of bodily processes. PMID:23752982

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

    In order to understand Sturm's concept of a universal mathematics as a replacement or complement of metaphysics, one first has to examine the evolution of the idea of a mathesis universalis up to Sturm, and his concept of metaphysics. According to the understanding of those times, natural theology belongs to metaphysics. The last section is concerned with Sturm's statements on the existence of God and his assessments for a physico-theology.

    1999-01-01

    The NASA Langley Research Center's Wind Tunnel Reinvestment project plans to shrink the existing data acquisition electronics to fit inside a wind tunnel model. Space limitations within a model necessitate a distributed system of Application Specific Integrated Circuits (ASICs) rather than a centralized system based on PC boards. This thesis will focus on the design of the prototype of the communication Controller board. A portion of the communication Controller board is to be used as the basis of an ASIC design. The communication Controller board will communicate between the internal model modules and the external data acquisition computer. This board is based around an Field Programmable Gate Array (FPGA), to allow for reconfigurability. In addition to the FPGA, this board contains buffer Random Access Memory (RAM), configuration memory (EEPROM), drivers for the communications ports, and passive components.

    Interpretation of hydraulic tests performed at a carbonate rock site for CO2 storage Berta Gómez, Sheila Fernández, Tobias Roetting, Lurdes Martínez, Silvia de Simone, Joaquim Soler, Jesus Carrera, Gema Ortiz, Christophe Huber, Carlos de Dios Proper design of CO2 geological storage facilities requires knowledge of the reservoir hydraulic parameters. Specifically, permeability controls the flux of CO2, the rate at which it dissolves, local and regional pressure buildup and the likelihood of induced seismicity. Permeability is obtained from hydraulic tests, which may yield local permeability, which controls injectivity, and large scale permeability, which controls pressure buildup at the large scale. If pressure response measurements are obtained at different elevations, hydraulic tests may also yield vertical permeability, which controls the rate at which CO2 dissolves. The objective of this work is to discuss the interpretation of hydraulic tests at deep reservoirs and the conditions under which these permeabilities can be obtained. To achieve this objective, we have built a radially symmetric model, including a skin and radial as well as vertical heterogeneity. We use this model to simulate hydraulic tests with increasing degrees of complexity about the medium response. We start by assuming Darcy flow, then add coupled mechanical effects (fractures opening) and, finally, we add thermal effects. We discuss how these affect the conventional interpretation of the tests and how to identify their presence. We apply these findings to the interpretation of hydraulic tests at Hontomin.

  8. Soil and Plant Mercury Concentrations and Pools in the Arctic Tundra of Northern Alaska by Hedge Christine, Obrist Daniel, Agnan Yannick, Moore Christopher, Biester Harald, Helmig Detlev

    2015-12-01

    We present vegetation, soil and runoff mercury (Hg) concentrations and pool sizes in vegetation and soils at several arctic tundra sites, an area that represents <7 x 106 km2 of land surface globally. The primary measurement location is at Toolik Field Station (TFS, 68° 38' N) in northern Alaska, with additional samples collected along a transect from TFS to the Arctic Ocean, and in Noatak National Preserve to be collected in August 2015. Soil and vegetation samples from all sites will be analyzed for total Hg concentration, pH, soil texture, bulk density, soil moisture content, organic and total carbon (C), nitrogen, along with major and trace elements. Initial results already obtained from TFS (characterized as moist to wet tundra with Typic Aquiturbel soils) show Hg concentrations in tundra vegetation (112±15 μg kg-1) and organic soil (140±8 μg kg-1) similar to those found in temperate sites. Calculation of plant-based Hg deposition rates by litterfall of 17.3 μg kg-1 yr-1 were surprisingly high, exceeding all other Hg deposition fluxes at this site. Hg concentrations in mineral soils (95±3 μg kg-1) were 2-3 times higher than those found at temperate sites. Hg concentrations showed weak relationships to organic C concentrations contrasting patterns from temperate soils where concentrations typically decline with depth following lower organic carbon contents. In fact, vertical mass profiles of Hg showed a strong increase with depth, with mineral layers storing over 90% (200-500 g ha-1) of Hg within these soils. A principle component analysis including major and trace elements indicated that soil Hg was not of lithogenic origin but from atmospheric sources, possibly by long-range transport. Carbon-14 dating results showed over 7,000 years old organic carbon in mineral soils of the active layer where highest concentrations of soil Hg were observed, suggesting long term retention of atmospheric Hg. These patterns suggest vertical translocation of Hg from the surface organic horizons to mineral soils and strong accumulation—possibly over millennia—therein.

    1993-02-01

    Fox (1990), in order to explain observations during the Axial Seamount Hydrothermal Emissions Study (ASHES), proposed a conceptual model for a two-phase subsea hydrothermal system in which steam controlled flow patterns by blocking liquid flow. An attempt is made here to demonstrate with a very general model that relative permeability contrasts by themselves do not cause spatial isolation of phases in steam/liquid water systems and that density segregation, independent of relative permeability effects, should not be ruled out as an explanation for the observations at the ASHES site. Fox replies that density segregation is probably not the only mechanism at work.

  11. Some Historical Points of Interest in Göttingen

    NASA Astrophysics Data System (ADS)

    Hentschel, Klaus

    The Georgia Augusta University of Göttingen, founded in 1737, was a child of the Enlightenment, and the new sciences have always played a major role here.1 Among the teachers of physics, physical chemistry, astronomy, and related subjects we find Johann Christian Polykarp Erxleben, Georg Christoph Lichtenberg, Johann Tobias Mayer, Carl Friedrich Gauss, Johann B. Listing, Wilhelm Eduard Weber, Woldemar Voigt, Friedrich Kohlrausch, Eduard Riecke, Walther Nernst and Peter Debye — the last two subsequently moved on to Berlin. In the 1920s, physics students were jestingly referred to as “Frankierte, Bornierte und Polierte” (loosely translated as stamped, limited and polished), in allusion to their teachers, the theoretical physicist Max Born and the experimentalists James Franck and Robert Wichard Pohl, the first two being important figures in the history of quantum theory, the third, one of the founding fathers of experimental solid state physics.2 The National Socialist’s rise to power had a devastating effect on this world-renowned center for physics and mathematics. Most of its high-caliber scientists either were dismissed on the basis of the racist “Law for the Restoration of the Professional Civil Service” or themselves felt compelled to emigrate: About a dozen members of the physics faculty, including Born and Franck, and ten from the mathematics faculty left Göttingen.3 After the war, Richard Becker, who in 1936 had received a compulsory order to take the chair for theoretical physics vacant since Born’s emigration, and Friedrich Hund, who was also an enthusiastic historian of science, distinguished themselves as physics teachers there but the university as a whole never recovered its international standing of before 1933 (see Figs. 1 and 2).

    PubMed

    Will, Bruno; Dalrymple-Alford, John; Wolff, Mathieu; Cassel, Jean-Christophe

    2008-09-01

    After having underlined the ambiguities of the concept of plasticity and the dangers of its purely metaphoric use in neurobiology, it is suggested that we return to a more precise definition of the structure, the operating principles and the function of the "systemic" unit or "integron" relevant to the particular level of analysis in question. Any change can then be described as a modification of function, a change in the operation principles, or an alteration of the material structure of the system. It is suggested that the term plastic should be restricted to describing, among the possible variations in the operating principles or the function of a given system, any lasting alteration of the connectivity network of the system under the influence of an external force or environmental constraint. Therefore, systematic or random variations of performance, functional flexibility or the vicarious(1) processes or strategies that can be found in a rigidly wired system are not justified examples of plasticity.

    Traumatic brain injury (TBI) caused by an explosive blast (blast-TBI) is postulated to result, in part, from transvascular transmission to the brain of a hydrodynamic pulse (a.k.a., volumetric blood surge, ballistic pressure wave, hydrostatic shock, or hydraulic shock) induced in major intrathoracic blood vessels. This mechanism of blast-TBI has not been demonstrated directly. We tested the hypothesis that a blast wave impacting the thorax would induce a hydrodynamic pulse that would cause pathological changes in the brain. We constructed a Thorax-Only Blast Injury Apparatus (TOBIA) and a Jugular-Only Blast Injury Apparatus (JOBIA). TOBIA delivered a collimated blast wave to the right lateral thorax of a rat, precluding direct impact on the cranium. JOBIA delivered a blast wave to the fluid-filled port of an extracorporeal intravenous infusion device whose catheter was inserted retrograde into the jugular vein, precluding lung injury. Long Evans rats were subjected to sublethal injury by TOBIA or JOBIA. Blast injury induced by TOBIA was characterized by apnea and diffuse bilateral hemorrhagic injury to the lungs associated with a transient reduction in pulse oximetry signals. Immunolabeling 24 h after injury by TOBIA showed up-regulation of tumor necrosis factor alpha, ED-1, sulfonylurea receptor 1 (Sur1), and glial fibrillary acidic protein in veins or perivenular tissues and microvessels throughout the brain. The perivenular inflammatory effects induced by TOBIA were prevented by ligating the jugular vein and were reproduced using JOBIA. We conclude that blast injury to the thorax leads to perivenular inflammation, Sur1 up-regulation, and reactive astrocytosis resulting from the induction of a hydrodynamic pulse in the vasculature.

    The forensic analysis of cocaine on currencies was optimized using a fractional, two-level experimental design that compared methanol and HCl extraction, SPE versus heptane pre-concentration, and extracted versus total ion chromatography. Subsequent student-initiated questions about levels of cocaine on U.S. and world currencies helped make connections to societal issues while teaching method optimization and chromatography. A significant correlation was found between the levels of cocaine and the age of the bills. Levels of cocaine on various world currencies followed expected drug-trafficking patterns with the highest levels found in the most developed countries.

  17. Reversed-phase liquid chromatographic determination of two manufacturing intermediates in D&C Red No. 34 and its lakes.

    PubMed

    Harp, Bhakti Petigara; Barrows, Julie N

    2009-01-01

    A reversed-phase LC method was developed to determine two manufacturing intermediates in the monosulfo monoazo color additive D&C Red No. 34 and its lakes. The analytes are 2-amino-1-naphthalenesulfonic acid (Tobias acid) and 3-hydroxy-2-naphthalenecarboxylic acid (3-hydroxy-2-naphthoic acid). This method can be used for batch certification of the color additives by the U.S. Food and Drug Administration to ensure that each lot meets published specifications for coloring drugs and cosmetics. The new method uses lithium oxalate in methanol-water to dissolve the color additives for analysis. The analytes were identified by comparison of their LC retention times and UV absorption spectra with those of standards. Peak area calibrations were generally linear (R > 0.999) and recoveries were 105% for Tobias acid and 103% for 3-hydroxy-2-naphthoic acid. The limits of determination (LOD) were 0.01% for Tobias acid and 0.03% for 3-hydroxy-2-naphthoic acid. The RSDs at the specification levels were 0.9% for Tobias acid and 3.2% for 3-hydroxy-2-naphthoic acid. Survey analyses of 14 samples of certified D&C Red No. 34 straight colors and lakes from six domestic and foreign manufacturers yielded results for Tobias acid that generally agreed with results previously obtained by using a gravity elution column chromatographic method. Nine of the results for 3-hydroxy-2-naphthoic acid were 2 to 5 times higher than the results obtained using the column chromatographic method. We attribute the lower accuracy of the column chromatographic method to incomplete solubility of the samples using the method conditions and difficulty with interpreting the UV spectrophotometric results.

  13. A new OH5 reconstruction with an assessment of its uncertainty.

    PubMed

    Benazzi, Stefano; Bookstein, Fred L; Strait, David S; Weber, Gerhard W

    2011-07-01

    The OH5 cranium, holotype of Paranthropus boisei consists of two main portions that do not fit together: the extensively reconstructed face and a portion of the neurocranium. A physical reconstruction of the cranium was carried out by Tobias in 1967, who did not discuss problems related to deformation, although he noted a slight functional asymmetry. Nevertheless, the reconstructed cranium shows some anomalies, mainly due to the right skewed position of the upper calvariofacial fragment and uncertainty of the relative position of the neurocranium to the face, which hamper further quantitative analysis of OH5's cranial geometry. Here, we present a complete virtual reconstruction of OH5, using three-dimensional (3D) digital data, geometric morphometric (GM) methods and computer-aided design (CAD) techniques. Starting from a CT scan of Tobias's reconstruction, a semi-automatic segmentation method was used to remove Tobias's plaster. The upper calvariofacial fragment was separated from the lower facial fragment and re-aligned using superposition of their independent midsagittal planes in a range of feasible positions. The missing parts of the right hemiface were reconstructed using non-uniform rational basis-spline (NURBS) surface and subsequently mirrored using the midsagittal plane to arrive at a symmetrical facial reconstruction. A symmetric neurocranium was obtained as the average of the original shape and its mirrored version. The alignment between the two symmetric shapes (face and neurocranium) used their independent midsagittal plane and a reference shape (KNM-ER 406) to highly reduce their degrees of freedom. From the series of alternative reconstructions, we selected the middle of this rather small feasible range. When reconstructed as a range in this way, the whole cranial form of this unique specimen can be further quantified by comparative coordinate-based methods such as GM or can be used for finite element modeling (FEM) explorations of hypotheses about

    2010-06-29

    Simultaneous measurement of effective thermal conductivity ({lambda}), effective thermal diffusivity ({kappa}) and specific heat of Ker fiber reinforced phenol formaldehyde composites have been studied by transient plane source (TPS) technique. The samples of different weight percentage typically (5, 10, 15, 20 and 25%) have been taken. It is found that values of effective thermal conductivity and effective thermal diffusivity of the composites decrease, as compared to pure phenol formaldehyde, as the fraction of fiber loading increases. Experimental data is fitted on Y. Agari model. Values of thermal conductivity of composites are calculated with two models (Rayleigh, Maxwell and Meredith-Tobias model). Good agreement between theoretical and experimental result has been found.

    Tobias Island, discovered in 1993 by the German research vessel RV Polarstern, is a system of low-lying banks and shoals hidden in sea ice 70 km off the northeastern coast of Greenland. Here we use satellite radar interferometry and airborne laser scanning to show that this island is 2 km long and 35 m high --- much larger than was originally reported. We have also been able to pinpoint the exact location of a stable area where a new group of small islands may be hidden. This demonstrates that satellite radar interferometry is an effective tool for finding ice-covered islands as well as for mapping them. PMID:11882882

  19. Verb and auxiliary movement in agrammatic Broca’s aphasia

    PubMed Central

    Bastiaanse, Roelien; Thompson, Cynthia K.

    2011-01-01

    Verb production in agrammatic Broca’s aphasia has repeatedly been shown to be impaired by a number of investigators. Not only is the number of verbs produced often significantly reduced, but verb inflections and auxiliaries are often omitted as well (e.g., Bastiaanse, Jonkers, & Moltmaker-Osinga, 1996; Saffran, Berndt, & Schwartz, 1989; Thompson, Shapiro, Li, & Schendel, 1994, 1997). It has been suggested that these problems are, in part, caused by the fact that finite verbs need to be moved from their base-generated position to inflectional nodes in the syntactic tree (e.g., Bastiaanse & Van Zonneveld, 1998). Others have suggested that production deficits in agrammatism can be predicted based on the position that certain structures take in the syntactic tree (Friedmann & Grodzinsky, 1997; Hagiwara, 1995). If the former theory is correct, several predictions can be made. First of all, the discrepancy between production of finite verbs in the matrix and embedded clause that has been found for Dutch (Bastiaanse & Van Zonneveld, 1998) should not be observed in English, since the word order of the matrix and embedded clause are the same in the latter language. Second, if verb movement (including movement of auxiliaries) is problematic for speakers with agrammatic aphasia, then a hierarchy in the production of auxiliaries in yes/no questions, auxiliaries, and finite verbs in declarative sentences in English would be expected, since the former has been moved and the two latter are in base-generated position. In the present paper, these hypotheses were tested in a cross-linguistic study of Dutch and English. Results showed the position in the syntactic tree does not predict deficit patterns; rather the critical factor appears to relate to whether or not verb or auxiliary movement is required.

    2012-01-01

    The 26th annual meeting of the Society for Immunotherapy of Cancer took place in Bethesda on November 4 to 6, 2011 and was organized by Charles G. Drake (Johns Hopkins University) Dolores J. Schendel (Helmholtz Zentrum Muenchen – German Research Center for Environmental Health Institute of Molecular Immunology), Jeffrey Schlom (National Cancer Institute, National Institutes of Health), and Jedd D. Wolchok (Memorial Sloan-Kettering Cancer Center). It was an event marked by a number of extraordinary circumstances: it attracted a record attendance of 805 participants from 24 different countries. The gathering came in the wake of great as well as very sad news for the tumor immunology community. Good news included the approval of anti-CTLA-4 as a therapy for metastatic melanoma in April and the announcement in early October of the Nobel Prize in Physiology and Medicine awarded to pioneering studies in the field of immunology. Indeed, one part of the prize went to Dr. Bruce Beutler, Scripps Research Institute, La Jolla, USA and Dr. Jules Hoffman, Institute for Molecular Cell Biology, Strasbourg, France, for their discoveries in innate immunity and the other part to Dr. Ralph Steinman, The Rockfeller University, New York, for his discovery of dendritic cells. Sad news was the losses of two giants in the field. Jürg Tschopp of the University of Lausanne in March and Ralph Steinman, who passed away just three days before his Nobel Prize announcement. The loss of these two charismatic scientific leaders was particularly sad for the Annual Meeting as both J. Tschopp and R. Steinman were confirmed speakers at this meeting: the former to deliver the keynote lecture and the latter as recipient of the Richard V. Smalley prize. PMID:22620286

  1. Shear-driven Dynamo Waves in the Fully Nonlinear Regime

    NASA Astrophysics Data System (ADS)

    2016-07-01

    Large-scale dynamo action is well understood when the magnetic Reynolds number (Rm) is small, but becomes problematic in the astrophysically relevant large Rm limit since the fluctuations may control the operation of the dynamo, obscuring the large-scale behavior. Recent works by Tobias & Cattaneo demonstrated numerically the existence of large-scale dynamo action in the form of dynamo waves driven by strongly helical turbulence and shear. Their calculations were carried out in the kinematic regime in which the back-reaction of the Lorentz force on the flow is neglected. Here, we have undertaken a systematic extension of their work to the fully nonlinear regime. Helical turbulence and large-scale shear are produced self-consistently by prescribing body forces that, in the kinematic regime, drive flows that resemble the original velocity used by Tobias & Cattaneo. We have found four different solution types in the nonlinear regime for various ratios of the fluctuating velocity to the shear and Reynolds numbers. Some of the solutions are in the form of propagating waves. Some solutions show large-scale helical magnetic structure. Both waves and structures are permanent only when the kinetic helicity is non-zero on average.

    2000-03-01

    Field effect sensors based on silicon carbide have been demonstrated for industrial applications at high temperatures and in rough environments. Metal insulator silicon carbide, MISiC, Schottky diode devices as well as FET transistor devices that can be operated up to 700°C are presented. For high operation temperatures the sensors respond within milliseconds to a change between an oxidizing and reducing atmosphere, and cylinder specific monitoring of a combustion engine has been demonstrated. Changing the temperature and the type of gate metal gives sensors with diverse response patterns to different components in e.g. exhaust gases and flue gases. Sensor devices operating around 300°C with some selectivity to nitric oxide in synthetic diesel exhaust gases are presented. At a higher temperature, about 500°C, some selectivity to HC is found in synthetic petrol exhausts. Boilers of the size 0.5 - 5 MW constitute a potential market for combustion monitoring sensors. We have demonstrated MISiC devices with high selectivity to carbon monoxide in flue gases. References: Fast responding air/fuel sensor for individual cylinder control, A. Baranzahi, P. Tobias, A.

  3. Variation among early Homo crania from Olduvai Gorge and the Koobi Fora region.

    PubMed

    Rightmire, G P

    1993-01-01

    Fossils recognized as early Homo were discovered first at Olduvai Gorge in 1959 and 1960. Teeth, skull parts and hand bones representing three individuals were found in Bed I, and more material followed from Bed I and lower Bed II. By 1964, L.S.B. Leakey, P.V. Tobias, and J.R. Napier were ready to name Homo habilis. But almost as soon as they had, there was confusion over the hypodigm of the new species. Tobias himself suggested that OH 13 resembles Homo erectus from Java, and he noted that OH 16 has teeth as large as those of Australopithecus. By the early 1970s, however, Tobias had put these thoughts behind him and returned to the opinion that all of the Olduvai remains are Homo habilis. At about this time, important discoveries began to flow from the Koobi Fora region in Kenya. To most observers, crania such as KNM-ER 1470 confirmed the presence of Homo in East Africa at an early date. Some of the other specimens were problematical. A.C. Walker and R.E. Leakey raised the possibility that larger skulls including KNM-ER 1470 differ significantly from smaller-brained, small-toothed individuals such as KNM-ER 1813. Other workers emphasized that there are differences of shape as well as size among the hominids from Koobi Fora. There is now substantial support for the view that in the Turkana and perhaps also in the Olduvai assemblages, there is more variation than would be expected among male and female conspecifics. One way to approach this question of sorting would be to compare all of the new fossils against the original material from Olduvai which was used to characterize Homo habilis in 1964. A problem is that the Olduvai remains are fragmentary, and none of them provides much information about vault form or facial structure. An alternative is to work first with the better crania, even if these are from other sites. I have elected to treat KNM-ER 1470 and KNM-ER 1813 as key individuals. Comparisons are based on discrete anatomy and measurements. Metric results

    Rae, Todd C; Koppe, Thomas

    2014-01-01

    The idea that people went through an aquatic phase at some time in their evolutionary past is currently undergoing a popular resurgence (see Foley & Lahr). This idea has even started to gain some traction in more learned circles; the late paleoanthropologist Phillip Tobias wrote in support of aspects of it in an edited e-book and a conference on the topic held recently in London was endorsed by celebrities such as the television presenter Sir David Attenborough. Despite (or perhaps because of) the lack of interest within the academic community, advocates of the concept continue to fill the media (and blogosphere) with challenges to the "savannah hypothesis" of the origins of people and to bemoan the fact that their views are not taken seriously by mainstream academia.

  6. Noise temperature improvement for magnetic fusion plasma millimeter wave imaging systems.

    2014-03-01

    Significant progress has been made in the imaging and visualization of magnetohydrodynamic and microturbulence phenomena in magnetic fusion plasmas [B. Tobias et al., Plasma Fusion Res. 6, 2106042 (2011)]. Of particular importance have been microwave electron cyclotron emission imaging and microwave imaging reflectometry systems for imaging T(e) and n(e) fluctuations. These instruments have employed heterodyne receiver arrays with Schottky diode mixer elements directly connected to individual antennas. Consequently, the noise temperature has been strongly determined by the conversion loss with typical noise temperatures of ~60,000 K. However, this can be significantly improved by making use of recent advances in Monolithic Microwave Integrated Circuit chip low noise amplifiers to insert a pre-amplifier in front of the Schottky diode mixer element. In a proof-of-principle design at V-Band (50-75 GHz), significant improvement of noise temperature from the current 60,000 K to measured 4000 K has been obtained. PMID:24689579

    The use of stem cells (SCs) as carriers for therapeutic agents has by now progressed to early clinical trials. These clinical trials exploring SC-mediated delivery of oncolytic adenoviruses will commence in the near future, hopefully yielding meritorious results that could provoke further scientific inquiry. Preclinical animal studies have demonstrated that SCs can be successfully loaded with conditionally-replicative adenoviruses and, then, delivered to the tumor, upon which they may evoke pronounced therapeutic efficacy in the animal (Ahmed et al., 2011; Ahmed et al., 2012; Thaci et al., 2012; Tobias et al., 2013). Here in this protocol, we describe the maintenance of SCs, provide an analysis of optimal adenoviral titers for SC loading, and evaluate the optimized viral loading on SCs. PMID:25827347

    Recently, two-dimensional microwave imaging diagnostics such as the electron cyclotron emission imaging (ECEI) system and microwave imaging reflectometry (MIR) have been developed to study magnetohydrodynamics instabilities and turbulence in magnetically confined plasmas. These imaging systems utilize large optics to collect passive emission or reflected radiation. The design of this optics can be classified into two different types: reflective or refractive optical systems. For instance, an ECEI/MIR system on the TEXTOR tokamak [Park et al., Rev. Sci. Instrum. 75, 3787 (2004)] employed the reflective optics which consisted of two large mirrors, while the TEXTOR ECEI upgrade [B. Tobias et al., Rev. Sci. Instrum. 80, 093502 (2009)] and systems on DIII-D, ASDEX-U, and KSTAR adopted refractive systems. Each system has advantages and disadvantages in the standing wave problem and optical aberrations. In this paper, a comparative study between the two optical systems has been performed in order to design a MIR system for KSTAR. PMID:21033960

    Ritter, Joachim R. R.

    The Institute of Geophysics at the University of Gottingen, Germany has a long tradition that began long before its official founding in January 1898. Its history goes back to at least 1756, to the work on geophysical problems by Tobias Meyer, Carl-Friedrich GauS, and Wilhelm Weber. At the beginning of the 20th century, the first director of the institute, Emil Wiechert, established a seismological working group that was a worldwide leader in this type of research for the next 10 to 12 years. In those golden years of seismology at Gottingen, famous students and co-workers of Wiechert such as G. H. Angenheister, L. Geiger, B. Gutenberg, L. Mintrop, and K. Zoeppritz made fundamental discoveries.

    Abstract Background The tribe Centistini includes three genera, Allurus, Centistes and Centistoides (Stigenberg et al. 2015). They are solitary endoparasitoids of adults and final instar larvae of beetles from the family Curculionidae (Jackson 1920, Aeschlimann 1980, Tobias 1986) New information In this paper we present a key, molecular data (standard DNA barcode, CO1) and images of the two species of Allurus occurring in the Western Palaearctic. A third Oriental species described from China (Taiwan) is also included in the key. Allurus is a Holarctic genus with three known species (A. choui, A. lituratus, A. muricatus). Our sequence data confirms that A. muricatus and A. lituratus are two distinct and separate species and this paper points out good and easy characters to separate them. PMID:27099556

    Superior sulcus tumors (SSTs), or as otherwise known Pancoast tumors, make up a clinically unique and challenging subset of non-small cell carcinoma of the lung (NSCLC). Although the outcome of patients with this disease has traditionally been poor, recent developments have contributed to a significant improvement in prognosis of SST patients. The combination of severe and unrelenting shoulder and arm pain along the distribution of the eighth cervical and first and second thoracic nerve trunks, Horner’s syndrome (ptosis, miosis, and anhidrosis) and atrophy of the intrinsic hand muscles comprises a clinical entity named as “Pancoast-Tobias syndrome”. Apart NSCLC, other lesions may, although less frequently, result in Pancoast syndrome. In the current review we will present the main characteristics of the disease and focus on the preoperative assessment. PMID:24672686

    Christopher Nolan's science fiction movie Interstellar offers a variety of opportunities for students in elementary courses on general relativity theory. This paper describes such opportunities, including: (i) At the motivational level, the manner in which elementary relativity concepts underlie the wormhole visualizations seen in the movie; (ii) At the briefest computational level, instructive calculations with simple but intriguing wormhole metrics, including, e.g., constructing embedding diagrams for the three-parameter wormhole that was used by our visual effects team and Christopher Nolan in scoping out possible wormhole geometries for the movie; (iii) Combining the proper reference frame of a camera with solutions of the geodesic equation, to construct a light-ray-tracing map backward in time from a camera's local sky to a wormhole's two celestial spheres; (iv) Implementing this map, for example, in Mathematica, Maple or Matlab, and using that implementation to construct images of what a camera sees when near or inside a wormhole; (v) With the student's implementation, exploring how the wormhole's three parameters influence what the camera sees—which is precisely how Christopher Nolan, using our implementation, chose the parameters for Interstellar's wormhole; (vi) Using the student's implementation, exploring the wormhole's Einstein ring and particularly the peculiar motions of star images near the ring, and exploring what it looks like to travel through a wormhole.

    The relationship between bedding planes and topographic slopes plays a major role in controlling landslide mechanisms. The catastrophic nature of many landslides around the Globe was proved to have a relevant structural background. This paper aims at analyzing the relationship between the spatial distribution of landslides and geological structure and lithology at a regional scale (1:50,000). Moreover, by automatizing a well known method to assess the influence of bedding planes on landslide occurence, this study further provides a GIS-based tool useful to speed up regional analyses, when study areas extend over hundreds or thousands of square kilometers. Three areas with different geological and geomorphological features and extents ranging from 70 to 179 km² were selected as case-studies. The sites are located in the Southern Carpathians, the Curvature and the Getic Subcarpathians of Romania. Computation of the topography - bedding plane relation required the following three phases: i) data acquisition, ii) developing a tool for an easy data processing and analysis and iii) testing the tool on the few selected sites having different geological and geomorphological settings. Three categories of spatial data were acquired: i) landslide inventory data; ii) detailed lithological data and iii) data related to geological structure (dip angle and dip direction point data). The landslide database was built based on interpretation of aerial images and field mapping during a more than 8 years long period. Lithology was extracted from geological maps at a 1:50,000 scale, while dip angle and dip direction data were obtained both from geological maps and direct measurements in the field meant to increase the level of detail. In order to rapidly identify the type of slope in relation to the geological structure (anaclinal, cataclinal and orthoclinal), a tool was developed which integrates a well-known index called TOBIA. This custom created GIS tool was developed using Python

    Superconducting melt-textured bulk (RE)BCO large grain materials are one of the most promising materials for power applications of high temperature superconductivity at the liquid nitrogen temperature range. Industrial applications are expected in high-speed low-loss magnetic bearings for flywheel energy storage devices, high-dynamic high-torque electric reluctance motors, and MAGLEV transportation systems. The material has high magnetic field trapping capability and therefore a new class of high-field superconducting permanent magnets will soon appear. However, there is still the need to improve the magnetic and mechanical material properties, as well as to increase the single domain size. This special issue contains papers concerning these topics presented at the International Workshop on the Processing and Applications of Superconducting (RE)BCO Large Grain Materials. The workshop was held on the 30 June-2 July 2003 in Jena, Germany, and was organized by the Institut fuer Physikalische Hochtechnologie, Jena. It was the fourth in the series of PASREG workshops after Cambridge, UK (1997), Morioka, Japan (1999), and Seattle, USA (2001). Sixty two contributions were presented at the workshop, 38 oral presentations and 24 poster presentations. This special issue contains 42 papers.

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

    On May 12, 1942, at Christopher coal mine No. 3 in Osage, West Virginia, a continent away from the frontlines of World War II, Superintendent Ed O'Neil saw the mine ventilation fan suddenly run backwards, propelled by a strong gust of air that tore the belt off the huge blower. The second shift mantrip of 115 coal miners, traversing the drift mouth for the 3:00 p.m. shift, ground to an uneasy halt. The article recounts the tragic consequences of this incident. It also tells of other events affecting coal miners during World War I and World War II.

    We have in our celestial backyard, a prime example of a variable star. The Sun, long thought to be "perfect" and unvarying, began to reveal its cycles in the early 1600s as Galileo Galilei and Christoph Scheiner used a telescope to study sunspots. For the past four hundred years, scientists have accumulated data, showing a magnetic cycle that repeats, on average, every eleven (or twenty-two) years. In addition, modern satellites have shown that the energy output at radio and x-ray wavelengths also varies with this cycle. This talk will showcase the Sun as a star and discuss how solar studies may be used to understand other stars.

    The goal of this project is to develop an Application Specific Integrated Circuit (ASIC) for use in the control electronics of the Spacecraft Optical Disk Recorder (SODR). Specifically, this project is to design an extendable memory buffer controller ASIC for rate matching between a system Input/Output port and the SODR's device interface. The aforementioned goal can be partitioned into the following sub-goals: (1) completion of ASIC design and simulation (on-going via ASEE fellowship); (2) ASIC Fabrication (at ASIC manufacturer); and (3) ASIC Testing (NASA/LaRC, Christopher Newport University).

    The calculation of QCD corrections to the width difference {Delta}{Lambda} in the B{sub s}meson system is presented. The next-to-leading order corrections reduce the dependence on the renormalization scale significantly and allow for a meaningful use of hadronic matrix elements from lattice gauge theory. At present the uncertainty of the lattice calculations limits the prediction of {Delta}{Lambda}. The presented work has been performed in collaboration with Martin Beneke, Gerhard Buchalla, Christoph Greub and Alexander Lenz.

    An analysis of noise and vibration measurements was carried out for the gear box and the power house panels of the 50 kW Vertical Axis Wind Turbine (V.A.W.T.) operating at Christopher Point on Vancouver Island, B.C. The spectra of noise and vibration signals show strong peaks at the gear mesh frequency and its harmonics even under light load conditions. The sound power radiated from the power house panels is significantly higher than that radiated by the gear box casing. The analysis also indicates misalignment of the pinion shaft or eccentricity of the pinion and errors in the gear tooth profiles.

    Since the term “environmental ethics” began to be used a generation ago, it has covered many different kinds of environmental notions, problems, ethical systems, and forms of behavior. A variety of cases are presented and examined under two terms, environmental ethics and ecological morality, in an effort to illustrate different kinds of ethical objectives. In order to understand the connections between various strands of environmental ethics, personal and social values and subcultural norms of environmental ethics are examined under Christopher Stone's concept of moral pluralism. G. J. Warnock's notion of the “general object” of morality is proposed to integrate the variegated purposes of environmental ethics.

  1. Early evolution without a tree of life

    PubMed Central

    2011-01-01

    Life is a chemical reaction. Three major transitions in early evolution are considered without recourse to a tree of life. The origin of prokaryotes required a steady supply of energy and electrons, probably in the form of molecular hydrogen stemming from serpentinization. Microbial genome evolution is not a treelike process because of lateral gene transfer and the endosymbiotic origins of organelles. The lack of true intermediates in the prokaryote-to-eukaryote transition has a bioenergetic cause. This article was reviewed by Dan Graur, W. Ford Doolittle, Eugene V. Koonin and Christophe Malaterre. PMID:21714942

    Neurosurgeons are familiar with the anatomic investigations of Thomas Willis, but his intellectual legacy actually extends into the arena of philosophy. John Locke was a student of Willis while at Oxford, and this essay explores how some of Willis's anatomic discoveries might have influenced the ideas Locke expressed in his Essay Concerning Human Understanding. It also includes historical information about 17th century England and the group of men (including Christopher Wren and Robert Boyle) who worked with Willis and founded the Oxford Experimental Philosophy Club, which became the Royal Society.

    We report on a newly discovered letter by Christoph Rothmann, dated July 1st 1584, and addressed to Johann Ernst of Anhalt. The letter supports the earlier assumption that Johann Ernst recommended Rothmann to Landgrave Wilhelm of Hesse, as Rothmann asks for Johann Ernst's help on the matter in this new source. More importantly Rothmann refers to his attempts to make Copernicus' calculations compatible with the Ptolomean model, which demonstrates that already at this stage of his career he was working on such a compromise, and not only after being influenced by Raimarus Ursus or Tycho Brahe, as has been argued by some authors.

    La Isabela, the first European town in the New World, was established in 1494 by the second expedition of Christopher Columbus but was abandoned by 1498. The main motive for settlement was to find and exploit deposits of precious metals. Archaeological evidence of silver extraction at La Isabela seemed to indicate that the expedition had located and tested deposits of silver-bearing lead ore in the Caribbean. Lead isotope analysis refutes this hypothesis but provides new evidence of the desperation of the inhabitants of La Isabela just before its abandonment. PMID:17360699

  9. Generative design in architecture using an expert system

    NASA Astrophysics Data System (ADS)

    Gullichsen, E.; Chang, E.

    The mathematician-architect Christopher Alexander has devised a theory of objective architectural design. He believes that all architectural forms can be described as interacting patterns, all possible relationships of which are governed by generative rules. These form a pattern language' capable of generating forms appropriate for a given environmental context. The complexity of interaction among these rules leads to difficulties in their representation by conventional methods. Here, a Prolog-based expert system is presented which implements Alexander's design methodology to produce perspective views of partially and fully differentiated 3-dimensional architectural forms.

  10. Gyrokinetic Simulation of Global and Local Alfv'en Eigenmodes Driven by Neutral Beam Injection in DIII-D

    2012-10-01

    In ITER, convection of fusion-produced alpha particles by energetic particle (EP)-driven Alfv'en eigenmodes (AEs) risks wall damage and loss of alpha heating needed for ignition. We examine beam-excited AEs and induced quasilinear transport in a DIII-D AE experiment using the gyrokinetic code GYRO [1]. Global, linear eigenvalue simulations show reverse-shear AEs (RSAEs), toroidal AEs, and beta-induced AEs interacting over one (equilibrium time scale) RSAE frequency sweep. Eigenfunction modifications over MHD, including a poloidal twist and broad AE footprint observed in electron cyclotron emission imaging [2], show the value of a kinetic approach. Under a simple quasilinear saturation assumption, a sequence of comparatively inexpensive local simulations quantitatively recreates some global features, notably the quasilinear transport footprint. Accordingly, we present here a stiff EP transport model where AEs limit the EP density gradient to the local stability threshold, and a TGLF-driven quasilinear model elsewhere. The model gives some``worst case'' predictions of the AE-limited alpha profile in ITER.[4pt] [1] J. Candy and R.E. Waltz, Phys. Rev. Lett. 91, 045001 (2003). [2] B.J. Tobias, et al., Phys. Rev.

    The studies of Klatzo, Miquel, Tobias and Haymaker (1961) have shown that one of the earliest and most sensitive indications of the effects of alpha-particle irradiation on rat bran is the appearance of glycogen granules mainly in the neuroglia of the exposed area of the brain. Periodic acid-Schiff (PAS) positive, alpha-amylase soluble granules were demonstrated within 12 hr after irradiation, preceding by approximately 36 hr the first microscopically detectable vascular permeability disturbances, as shown by the fluorescein labeled serum protein technique. These studies suggested that the injurious effects of alpha-particle energy were on cellular elements primarily, according to the physical properties and distribution of the radiation in the tissue, and that the vascular permeability disturbances played a secondary role in pathogenesis. The purpose of this study was to correlate the histochemical observations on glycogen with a quantitative assessment of the glycogen in the irradiated brain tissue. It is felt that such a study may contribute to the understanding of radiation injury at the molecular level. A practical aspect of this problem is that the information on biological radiation effects due to accelerated particles from the cyclotron source, is employed in this study, is applicable to radiation from cosmic particles both in free space and entrapped in the Van Allen belts.

    Despite the fact that ionic liquid-based aqueous two phase systems (ATPSs) have been widely studied for extraction purposes, the adequacy of biodegradable organic salts as salting out agents has been left unexploited. In this study, we investigated the ability of sodium-based organic salts in the formation of ATPS in the presence of a common ionic liquid, [C4mim]BF4. In the pioneering aspect of this work, Response Surface Methodology (RSM) based on three-variable central composite design (CCD) was employed for determination of the effect of pH and the initial concentration of phase components on the partition coefficient of Cefalexin. Consequently, regression model equations and contour plots were applied to evaluate the effect of system's parameters on biomolecule's extraction. The tie-line (TL) data were determined for each experimental run and their reliability was confirmed by Othmer-Tobias and Bancroft correlations. In order to investigate the salting-out ability the effective excluded volume (EEV) was determined from the binodal data. Furthermore, FTIR spectra confirmed no chemical interactions between Cefalexin and [C4mim]BF4 in the extraction process. The microscopic structure of the top phase was analyzed by DLS, conductivity and TEM in order to investigate the mechanism of extraction. Hydrophobic interaction, the salting-out effect and the aggregation phenomena played the dominant role in the study of the extraction process. PMID:25407265

    The largest concentrations of free energy in the universe are the radio lobes associated with the central galactic black hole formation, in form of magnetic energy, ˜10^62 ergs of B^2/8π, ˜10% of MBH c^2. It's generally believed that the magnetic fields are amplified from very weak seed fields by the interaction of electrically conducting fluid motion, the so-called dynamo mechanism. Turbulence inhibits a dynamo, which must have coherence and phase information (Cattaneo and Tobias) in Baryon-dominated hydrodynamics. We are attempting an experiment to demonstrate an αφ dynamo in New Mexico Institute of Mining and Technology with liquid sodium in limiting stable Couette flow between two co-rotating cylinders, φ1=17.5Hz and φ2=70Hz, 60cm and 30cm in diameter. The Helicity is produced by driven plumes analogous to star-disk collisions in the astrophysical limit. Including signals from 18 Hall detectors, 5 pressure and 5 temperature sensors in rotating frame, 2 rotation speed, 2 current, 2 torque sensors, and other sensors in stationary to monitor the experimental apparatus operation, there are more than 45 signals must be digitized and transmitted in serial, and finally decoded in data acquisition computer to characterize the experiment.

    Already since the mid-19th century, it was a task of the Imperial-Royal Austro-Hungarian Navy not only to take part in military actions, to train sea cadets, to strengthen diplomatic relations, and to protect the coasts, the sea trade, and Austrian citizens in far countries, but also to carry out coast surveys and soundings, as well as scientific observations during their missions. On a trip around the earth, Tobias von Österreicher, commander of the corvette "Erzherzog Friedrich", was instructed to observe the Venus transit of December 8, 1874 in Yokohama. This order was only one out of many that he had to fulfill: to train the Navy cadets, to explore the possibility of the installation of a colony on the island of Borneo, to meet diplomats and consulate representatives, to carry out soundings and coast surveys to improve sea-charts, and to make meteorological observations. The "qualification list" indicates that all these tasks were fulfilled according to expectations. However, an incident on Borneo in 1875 took the life of two of his sailors. In its aftermath he did not react according to rules, he was reproached by the Navy Section of the Imperial War Ministry, and his career as a ship commander came to an end. Besides the Austrian expedition to observe the Venus transit of 1874 in Yokohama, a second one was carried out by the astronomers Eduard Weiss and Theodor Oppolzer in Jassy (Romania), which was supported by the Vienna Academy of Sciences.

    Examination of some freshwater and brackishwater (estuarine) fishes in South Carolina in October 2009 yielded, in addition to other parasites, 2 little-known nematode species identified as Dichelyne fastigatus Chandler, 1935 (Cucullanidae), from the red drum, Sciaenops ocellatus (Linnaeus), from an estuary, and Rhabdochona ovifilamenta Weller, 1938 (Rhabdochonidae), from the shorthead redhorse, Moxostoma macrolepidotum (Lesueur), from Lake Moultrie. Light and scanning electron microscopy (the latter used for the first time for these species) made it possible to describe several important, but previously unreported, taxonomic features in D. fastigatus, such as the location of the excretory pore and deirids, the shape of deirids and a gubernaculum, the shape and size of eggs, the presence of precloacal ventral oblique muscle bands, and 11 pairs of caudal papillae and a pair of phasmids. It distinctly differs from the most similar Dichelyne cotylophora (Ward and Magath, 1917), a parasite of North American freshwater percids, in the number and arrangement of postanal papillae and by a markedly elevated cloacal region. Records of Dichelyne lintoni Barreto, 1922, from S. ocellatus probably concern D. fastigatus. Examination of R. ovifilamenta revealed a high degree of morphologic and biometric variability in this species. Based on our analysis, Rhabdochona laurentiana Lyster, 1940 , Rhabdochona milleri Choquette, 1951, and Rhabdochona catostomi Kayton, Kritsky, and Tobias, 1979, are synonymized with R. ovifilamenta Weller, 1938, typically a parasite of North American catostomids.

  16. Non-axisymmetric magneto- hydrodynamic equilibrium in the presence of internal magnetic islands and external magnetic perturbation coils

    Non-axisymmetric equilibria arise in DIII-D discharges that are subjected to magnetic perturbation by 3D magnetic coils. But, 3D shaping of the entire plasma, including the boundary, also occurs in the rotating fluid frame of saturated internal magnetic islands (Tobias et al 2013 Plasma Phys. Control. Fusion 55 095006). This is advantageous since internal islands and kink responses that rotate near the fluid velocity of the plasma are easily diagnosed, while static perturbations in the laboratory frame are not. The helicity of the perturbed shape is the same in both rotational frames of reference, making one mode a diagnostic proxy for the other and allowing internal modes to be used as a source of data for comparison to models typically applied to understanding the effect of static perturbations. Discrepancies with ideal magneto-hydrodynamic equilibrium obtained by the IPEC (Park et al 2007 Phys.

    Modern humans are characterized by specialized hand morphology that is associated with advanced manipulative skills. Thus, there is important debate in paleoanthropology about the possible cause–effect relationship of this modern human-like (MHL) hand anatomy, its associated grips and the invention and use of stone tools by early hominins. Here we describe and analyse Olduvai Hominin (OH) 86, a manual proximal phalanx from the recently discovered >1.84-million-year-old (Ma) Philip Tobias Korongo (PTK) site at Olduvai Gorge (Tanzania). OH 86 represents the earliest MHL hand bone in the fossil record, of a size and shape that differs not only from all australopiths, but also from the phalangeal bones of the penecontemporaneous and geographically proximate OH 7 partial hand skeleton (part of the Homo habilis holotype). The discovery of OH 86 suggests that a hominin with a more MHL postcranium co-existed with Paranthropus boisei and Homo habilis at Olduvai during Bed I times. PMID:26285128

    Significant progress has been made in the imaging and visualization of magnetohydrodynamic and microturbulence phenomena in magnetic fusion plasmas [B. Tobias et al., Plasma Fusion Res. 6, 2106042 (2011)]. Of particular importance have been microwave electron cyclotron emission imaging and microwave imaging reflectometry systems for imaging T{sub e} and n{sub e} fluctuations. These instruments have employed heterodyne receiver arrays with Schottky diode mixer elements directly connected to individual antennas. Consequently, the noise temperature has been strongly determined by the conversion loss with typical noise temperatures of ∼60 000 K. However, this can be significantly improved by making use of recent advances in Monolithic Microwave Integrated Circuit chip low noise amplifiers to insert a pre-amplifier in front of the Schottky diode mixer element. In a proof-of-principle design at V-Band (50–75 GHz), significant improvement of noise temperature from the current 60 000 K to measured 4000 K has been obtained.

  19. The effects of a test-taking strategy intervention for high school students with test anxiety in advanced placement science courses

    Markus, Doron J.

    Test anxiety is one of the most debilitating and disruptive factors associated with underachievement and failure in schools (Birenbaum, Menucha, Nasser, & Fadia, 1994; Tobias, 1985). Researchers have suggested that interventions that combine multiple test-anxiety reduction techniques are most effective at reducing test anxiety levels (Ergene, 2003). For the current study, involving 62 public high school students enrolled in advanced placement science courses, the researcher designed a multimodal intervention designed to reduce test anxiety. Analyses were conducted to assess the relationships among test anxiety levels, unit examination scores, and irregular multiple-choice error patterns (error clumping), as well as changes in these measures after the intervention. Results indicate significant, positive relationships between some measures of test anxiety and error clumping, as well as significant, negative relationships between test anxiety levels and student achievement. In addition, results show significant decreases in holistic measures of test anxiety among students with low anxiety levels, as well as decreases in Emotionality subscores of test anxiety among students with high levels of test anxiety. There were no significant changes over time in the Worry subscores of test anxiety. Suggestions for further research include further confirmation of the existence of error clumping, and its causal relationship with test anxiety.

    As we approach the twenty-first century, the college population is becoming increasingly diverse. Research suggests that gender, racial and cultural differences can affect a student's response to different teaching methods. How can undergraduate astronomy courses be better designed to accommodate more of these diverse learning styles? This question was the focus of my participation in the University of Maryland's summer Curriculum Transformation Project. Selected on the basis of their proposed projects, twelve faculty members explored the issues of diversity in a seminar format for six weeks. Through group readings, awareness of common problems across the disciplines were examined. Individual exploration allowed each participant to focus on specific course transformation. I examined the research of Sheila Tobias presented in ``They're Not Dumb, They're Different: Stalking the Second Tier" and ``Revitalizing Undergraduate Science: Why Some Things Work and Most Don't." Application of this summer's work to introductory astronomy for non-science majors has resulted in an attempt to accommodate a greater variety of learning styles. Changes in my course include the use of electronic mail through Listserv in a class of 200 students, introduction of more cooperative learning activities, an improved, user-friendly syllabus, rewards for active participation in lecture, enhanced visual presentations, and promotion of a less competitive classroom atmosphere.

  2. Poetry for physicists

    In an effort to discover what makes the humanities difficult and unpopular with some science and engineering students, 14 Cornell faculty from the disciplines of chemistry, physics, applied mathematics, geology, materials science, and engineering were invited to become ``surrogate learners'' in a junior/senior level poetry seminar designed expressly for them. Their encounter with humanistic pedagogy and scholarship was meant to be an extension of ``Peer Perspectives on Science'' [see S. Tobias and R. R. Hake, ``Professors as physics students: What can they teach us?'' Am. J. Phys. 56, 786 (1988)]. The results challenge certain assumptions about differences between scholarship and pedagogy in the humanities and science (as regards ``certainty'' and models). But the experiment uncovered other problems that affect ``marketing'' the humanities to science and engineering students. Results are some additional insights into what makes science ``hard'' for humanities students and why physical science and engineering students have difficulty with and tend to avoid courses in literature, as well as into what can make humanities courses valuable for science students.

    After his study of food science at the Rheinische Friedrich-Wilhelms University of Bonn, Tobias J Demetrowitsch obtained his doctoral degree in the research field of metabolomics at the Christian-Albrechts-University of Kiel. The present paper is part of his doctoral thesis and describes an extended strategy to evaluate and verify complex or large-scale experiments and data sets. Large-scale studies result in high sample numbers, requiring the analysis of samples in different batches. So far, the verification of such LC-MS-based metabolomics studies is difficult. Common approaches have not provided a reliable validation procedure to date. This article shows a novel verification process for a large-scale human urine study (analyzed by a LC/QToF-MS system) using a two-step validation procedure. The first step comprises a targeted approach that aims to examine and exclude statistical outliers. The second step consists of a principle component analysis, with the aim of a tight cluster of all quality controls and a second for all volunteer samples. The applied study design provides a reliable two-step validation procedure for large-scale studies and additionally contains an inhouse verification procedure. PMID:25558939

  4. Speech intelligibility index predictions for young and old listeners in automobile noise: Can the index be improved by incorporating factors other than absolute threshold?

    While young and old subjects with comparable audiograms tend to perform comparably on speech recognition tasks in quiet environments, the older subjects have more difficulty than the younger subjects with recognition tasks in degraded listening conditions. This suggests that factors other than an absolute threshold may account for some of the difficulty older listeners have on recognition tasks in noisy environments. Many metrics, including the Speech Intelligibility Index (SII), used to measure speech intelligibility, only consider an absolute threshold when accounting for age related hearing loss. Therefore these metrics tend to overestimate the performance for elderly listeners in noisy environments [Tobias et al., J. Acoust. Soc. Am. 83, 859-895 (1988)]. The present studies examine the predictive capabilities of the SII in an environment with automobile noise present. This is of interest because people's evaluation of the automobile interior sound is closely linked to their ability to carry on conversations with their fellow passengers. The four studies examine whether, for subjects with age related hearing loss, the accuracy of the SII can be improved by incorporating factors other than an absolute threshold into the model.

    While working with E.O. Lawrence at Berkeley, R.R. Wilson in 1946 noted the potential for using the Bragg-peak of protons (or heavier ions) for radiation therapy. Thus began the long history of contributions from Berkeley to this field. Pioneering work by C.A. Tobias et al at the 184-Inch Synchrocyclotron led ultimately to clinical applications of proton and helium beams, with over 1000 patients treated through 1974 with high-energy plateau radiation; placing the treatment volume (mostly pituitary fields) at the rotational center of a sophisticated patient positioner. In 1974 the SuperHILAC and Bevatron accelerators at the Lawrence Berkeley Laboratory were joined by the construction of a 250-meter transfer line, forming the Bevalac, a facility capable of accelerating ions of any atomic species to relativistic energies. With the advent of these new beams, and better diagnostic tools capable of more precise definition of tumor volume and determination of the stopping point of charged-particle beams, large-field Bragg-peak therapy with ion beams became a real possibility. A dedicated Biomedical experimental area was developed, ultimately consisting of three distinct irradiation stations; two dedicated to therapy and one to radiobiology and biophysics. These facilities included dedicated support areas for patient setup and staging of animal and cell samples, and a central control area linked to the main Bevatron control room.

  6. The motivational stories of how women become scientists: A hermeneutic phenomenological inquiry

    The under-representation of women in science careers is well documented (Astin, Green, Korn, & Riggs, 1991; Felder, Felder, Mauny, Hamrin, & Dietz, 1995; Green, 1989; National Science Foundation, 1996, 1998; Seymour & Hewitt, 1997; Strenta, Elliot, Adair, Scott, & Matier, 1994; Tobias, 1990, 1992). While important information has been published concerning various factors that influenced women to pursue science careers (American Association of University Women, 1992; Debacker & Nelson, 2000; Samuels, 1999), very few research projects have allowed women scientists to share their personal experiences of what motivated them to become scientists in their own voices. The purpose of this inquiry was to investigate the elicited stories of seven women research scientists so that their retrospective motivational experiences with science as girls and young women inside and outside the formal school setting might be better understood. This inquiry examined specific motivational factors and experiences that encouraged or discouraged these women to pursue careers in science. These factors included the motivational influences of gender perceptions, science experiences, and social interactions. From the collective experiences offered, emergent themes were identified and interpreted. These motivational themes were compared with motivational findings in the literature review. Educational implications of the identified themes for these and other women considering careers in science, women's parents, science educators and society, are discussed.

    2014-07-01

    Aims: The present high accuracy of stellar positions and proper motions allows us to determine the positional accuracy of old stellar catalogues. This has already been done for the most important catalogues from before the 18th century. Our aim is to extend this study to several 18th century catalogues. Methods: To do this, I studied ten catalogues: those of Flamsteed and Rømer, four catalogues of La Caille, and catalogues of Tobias Mayer, Bradley, Piazzi, and Lalande. A comparison with modern data, mostly from Hipparcos, compiled in the Simbad database of the CDS allowed me to determine the position errors of these catalogues. I also compared the stellar visual magnitudes given in eight of these catalogues with photometric V magnitudes. Results: Thanks to novel instruments, the rms positional accuracy improved from thousands to hundreds of arcsec in older catalogues to less than one minute in that of Flamsteed, and to 2-6 arcsec in the other catalogues I examined. These improvements allowed for the first time relatively accurate proper motions to be determined by 19th century astronomers. The catalogues with some corrections are available in digital form at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/567/A26

    In September of 2001 a cabled vertical linear array (VLA) of hydrophones was deployed on Pioneer Seamount, 90 km off the California coast near Half Moon Bay, by the NOAA-PMEL and University of Washington-APL. The array of 4 hydrophones is at a depth of 950 m, and the four signals are digitized at the shore end of the cable at 1000 Hz. The data are archived by PMEL, and are available to the public over the internet. Spectrograms of all of the data are accessible on the SFSU web site. A large number of blue-whale calls are evident in the spectrograms. We have employed spectrogram correlation [Mellinger 2000] and a matched-filter detection scheme [Stafford 1998] to automatically identify these whale calls in three months of data. Results on the frequency of calls and their variability will be presented. Mellinger, David K., and Christopher W.

    This study compares terminal cancer care in 1967-69 with care in 1977-79 as evaluated by surviving spouses of patients who died in St Christopher's Hospice and other local hospitals. Patients and their surviving spouses reported less personal distress in both settings in 1977-79 than in 1967-69 and the patients were also thought to have suffered less pain. These differences were found before, during and, in surviving spouses, after the period of terminal care. They were confirmed in subsamples of 30-34 patients matched for age, sex, socio-economic status and duration of terminal period. Improvements may be attributable to the training in terminal care provided by staff of the Hospice since 1967 and augmented in its Study Centre which was opened in 1973. Although pain and distress in the patient is no longer a major problem in either setting, spouses in 1977-79 remain less anxious at St Christopher's Hospice than at other hospitals; they play a larger part in the care of the patient and are in closer contact with staff before and after bereavement.

    In 2009, the Air and Waste Management Association invited their annual critical review on the topic of measurement of surface particulate air pollution from satellites (Hoff and Christopher, 2009). At that time, over thirty publications had addressed the relationship between aerosol optical depth measured from satellites and the emissions, transport, and exposure at the surface from man-made haze, dust, and smoke. I will revisit the conclusions reached in that critical review, which we subtitled "Have we reached the promised land". Five years later and dozens of subsequent publications later on this topic, have we really advanced the state of the science in relating optical properties to surface measurements or are we just generating more data? The VIIRS imager and the upcoming GOES-R imager have the potential to provide higher spatial and temporal observations of aerosol optical depth from space. But to address the need for quantitatively improving estimates of exposure at the surface, is this enough or do we need to combine observing systems to address the real physics of the problem?

    This study focuses on a relatively unexplored area located some 33.4 geodetic km away from the central floor of Euclides, in the NE direction, precisely at -6.62° Latitude and -29.89° Longitude. Land-based CCD observations of this area showed a small group of dome-like structures situated on an elevated basaltic platform. One hypothesis is that these features represent a series of mounds made up of a collection of undifferentiated crater materials or ejecta as described by USGS (Geologic Atlas of the Moon. Department of Interior, US Geological Survey—I-458, 1965). This hypothesis is tested against an alternative one in that the area shows the presence of domes that are partly covered by these ejecta. The present spectrometric results place the basalt within the chosen AOI subset in the low-Ti category (1-5 wt% TiO2) and a FeO abundance wt% of between 12 and 14. Spectrometrically, similar dome features have been observed by other investigators near the Milichus/Tobias Mayer regions. A possible classification for this feature would be DW/1a/6h/8j. Details of the cluster analysis used for raster classification is presented as an effective approach to discriminate between different classes of the lunar surface. This approach was used to map the lunar soil geology over the selected showing better lunar geological information than the current mapping information available by USGS. This same approach can be used to effectively map out other regions of the lunar surface.

    Characteristics of dune-paleosol-sequences in Fuerteventura. - What should be questioned? Dominik Faust, TU Dresden, Germany Tobias Willkommen, TU Dresden, Germany Yurena Yanes, CSIC Granada/Cincinatti, Spain/USA David Richter, TU Dresden, Germany Ludwig Zöller, Uni Bayreuth, Germany The northern part of Fuerteventura is characterized by large dune fields. We investigated dune-paleosol-sequences in four pits to establish a robust stratigraphy and to propose a standard section. An interaction of processes like dune formation, soil formation and redeposition of soils and sand are most important to understand the principles of landscape development in the study area. To our mind a process cycle seem to be important: First climbing-dunes are formed by sand of shelf origin. Then soil formation could have taken place. Soil and/or sand were then eroded and deposited at toe slope position. This material in turn is the source of new sand supply and dune formation. The described cycle may be repeated several times and this ping-pong-process holds on. The results are sections composed of dune layers, paleosols and colluvial material interbedded. Fundamental questions still remain unanswered: Is climate change responsable for changes in process combination (e.g. from dune formation to soil formation)? Or are these features due to divergence phenomenon, where different effects/results (dune and soils) may be linked to similar causes (here: climate)? Assuming that different features (soils and dunes) were formed under one climate, increasing soil forming intensity could be mainly a function of decreasing sand supply. This in turn could be caused by reduced sand production (s. ZECH et al. accepted). However geochemical data and mollusc assemblages point to changing environments in space and even climate modifications in time.

  17. Ultra-performance liquid chromatographic determination of manufacturing intermediates and subsidiary colors in D&C Red No. 34 and its lakes.

    2011-01-01

    An ultra-performance liquid chromatography (UPLC) method was developed to determine the manufacturing intermediates and subsidiary colors in the monosulfo monoazo color additive D&C Red No. 34 and its lakes. This method is currently used for batch certification of the color additives by the U.S. Food and Drug Administration to ensure that each lot meets published specifications for coloring drugs and cosmetics. The new UPLC method has replaced an HPLC method for determining the intermediates and a TLC method for determining the subsidiary colors. The intermediates are 2-amino-1-naphthalenesulfonic acid (Tobias acid) and 3-hydroxy-2-naphthalenecarboxylic acid (3-hydroxy-2-naphthoic acid). Subsidiary colors are positional isomers of the major dye component or related compounds containing lower numbers of substituent groups. The analytes are identified by comparison of their UPLC retention times and UV or visible absorption spectra with those of standards. Validation studies showed that peak area calibrations for the analytes were generally linear (R > 0.999), and recoveries were 98-103%. The LODs were 0.002-0.02%, and the RSDs at the specification levels were 0.7-2.2%. Survey analyses of 12 samples of certified D&C Red No. 34 straight colors and lakes from six domestic and foreign manufacturers yielded results for the intermediates by UPLC and HPLC that were consistent within experimental error. The UPLC analyses yielded results for the subsidiary colors that were consistently lower than results previously obtained by TLC, which we attribute to limitations of the TLC method. The new UPLC method provides sharper peaks, better peak separation, and faster analysis times than the formerly used HPLC method and is more accurate, much faster, and much less labor-intensive than the formerly used TLC method.

    San Jose, capital city of Costa Rica, fills the valley between two steep mountain ranges. In this image made from data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite, visible, shortwave, and near-infrared wavelengths of light that the sensor observed have been combined to produce a false-color version of the scene in which vegetation is red, urban areas are silvery gray, water is dark blue, and clouds are white. The image was captured on February 8, 2007. San Jose is in the center of the image. The Rio Torres winds through downtown San Jose. Cartago, the much smaller colonial capital, sits in the lower right corner, while the city of Alajuela appears across the river, northwest of San Jose. The cities' manmade surfaces contrast sharply with the lushly vegetated landscape surrounding the city. Greenhouses are common in the region, and their glass roofs may be the brilliant white spots around the outer edges the cities. The long, straight runway of the Tobias Bolanos International Airport is visible as a dark line southeast of Alajuela. The landscape around the two cities shown here is rugged. Steep mountain peaks cast dark shadows across their leeward slopes. Patches of dark red vegetation on the mountains north of San Jose may be rainforest. Coffee plantations also cover the slopes of the mountains around the city. February is the dry season in Costa Rica. During the rainy season, from about April to November, clouds usually block the satellite's view of this tropical location.

  20. Process Damping Parameters

    2011-12-01

    The phenomenon of process damping as a stabilising effect in milling has been encountered by machinists since milling and turning began. It is of great importance when milling aerospace alloys where maximum surface speed is limited by excessive tool wear and high speed stability lobes cannot be attained. Much of the established research into regenerative chatter and chatter avoidance has focussed on stability lobe theory with different analytical and time domain models developed to expand on the theory first developed by Trusty and Tobias. Process damping is a stabilising effect that occurs when the surface speed is low relative to the dominant natural frequency of the system and has been less successfully modelled and understood. Process damping is believed to be influenced by the interference of the relief face of the cutting tool with the waveform traced on the cut surface, with material properties and the relief geometry of the tool believed to be key factors governing performance. This study combines experimental trials with Finite Element (FE) simulation in an attempt to identify and understand the key factors influencing process damping performance in titanium milling. Rake angle, relief angle and chip thickness are the variables considered experimentally with the FE study looking at average radial and tangential forces and surface compressive stress. For the experimental study a technique is developed to identify the critical process damping wavelength as a means of measuring process damping performance. For the range of parameters studied, chip thickness is found to be the dominant factor with maximum stable parameters increased by a factor of 17 in the best case. Within the range studied, relief angle was found to have a lesser effect than expected whilst rake angle had an influence.

    As originally proposed, the authors constructed a new Scanning Transmission X-ray Microscope, STXM IV. The design and construction was led by Chris Jacobsen, and involved graduate students Michael Feser, Mary Carlucci-Dayton and Tobias Beetz. This microscope has the following new features: It has a new and improved high resolution scanning stage that should make it possible to perform higher resolution imaging without distortions. Preliminary results indicate that the stage performs as designed. It has an enclosure that can be evacuated and backfilled with helium. This makes it possible to perform imaging in the neighborhood of the nitrogen and oxygen edges without interference from residual air. It has a motorized detector stage for easy interchange of detectors and alignment microscope. We expect to use this to align the new segmented detector which makes it possible to perform brightfield and dark field microscopy simultaneously, and to record images in differential phase contrast as well. The microscope is located upstream of cryoSTXM, the instrument we use to examine specimens in a frozen hydrated state. The design of STXM IV is such that it makes it quick and easy to switch between STXM IV and cryo-STXM operations and vice versa. IEEE488 based control electronics provides multiple channels of data collection. The microscope is run from a LINUX PC with all new software, developed in-house. The stages for the zone plate and the order sorting aperture (OSA) have kinematic mounts. This way different sets of zone plates (optimized for different wavelengths and working distances) can be exchanged without the need for complete realignment of the instrument. The enclosure can be used as a glove-box, making it possible to examine specimens which require anaerobic handling.

  2. Spin transistor action via tunable Landau-Zener transitions in magnetic semiconductor quantum wells

    2013-03-01

    Spin-transistors, employing spin-orbit interaction like Datta-Das prototypes, principally suffer from low signal levels due to limitations in spin injection efficiency, fast spin relaxation and dephasing processes. Here we present an alternative concept to implement spin transistor action where efficiency is improved by keeping spin transport adiabatic. To this end a helical stray field B, generated by ferromagnetic Dysprosium stripes, is superimposed upon a two-dimensional electron system in (Cd,Mn)Te, containing Mn ions with spin 5/2. Due to the giant spin splitting, occurring at low temperatures and small B in (Cd,Mn)Te quantum wells, the B-helix translates into a spin-helix and the electron spins follow adiabatically the imposed spin texture. Within this approach the transmission of spin-polarized electrons between two contacts is regulated by changing the degree of adiabaticity, i.e. an electron's ability to follow the spin helix. This is done by means of a small applied homogeneous magnetic field while the degree of adiabaticity is monitored by the channel resistance. Our scheme allows spin information to propagate efficiently over typical device distances and provides an alternative route to realize spintronics applications. We note that our concept is not restricted to a particular choice of materials, temperature, methods of spin injection, manipulation as well as detection.

  3. Test of socioeconomic causation of secular trend: stature changes among favored and oppressed South Africans are parallel.

    Secular trends in body height, however common, run at different rates and even in opposite directions in various populations. The standard explanation is that direction and tempo of the trend are reflections of changes in the socioeconomic situation. The aim of this work is to test this hypothesis by examining trends in different socioeconomic groups living in the same country. Our observations on affluent South Africans of European extraction (AE) and on Polish medical students are compared with the data on statures of other affluent and poor peoples from the two countries measured at various dates during the 19th and 20th centuries. The trend among native Southern Africans is erratic (Tobias: South African Journal of Medical Science 40:145-164, 1975), but the overall direction is positive with a slow rate (0.24 cm/decade for 72 Negroid male groups and 0.48 cm/d for 28 Khoisan male samples). Magnitude of the trend among adult AE (0.41 cm/d for females, 0.59 for males) does not differ significantly from that among natives. The trend was absent in the data for 10-year-old AE boys and girls. The rate of trend among AE is much lower than that in their countries of origin (mainly Holland and Britain). The trend among AE medical students is markedly weaker than the trend among Polish medical students (1.21 cm/d), who in turn parallel Polish general conscripts (1.24 cm/d). It follows that the explanation of the secular trend as being an ecosensitive response of individuals to changing levels of well-being is insufficient. PMID:2275483

  4. The across frequency independence of equalization of interaural time delay in the equalization-cancellation model of binaural unmasking

    Akeroyd, Michael A.

    2004-08-01

    The equalization stage in the equalization-cancellation model of binaural unmasking compensates for the interaural time delay (ITD) of a masking noise by introducing an opposite, internal delay [N. I. Durlach, in Foundations of Modern Auditory Theory, Vol. II., edited by J. V. Tobias (Academic, New York, 1972)]. Culling and Summerfield [J. Acoust. Soc. Am. 98, 785-797 (1995)] developed a multi-channel version of this model in which equalization was ``free'' to use the optimal delay in each channel. Two experiments were conducted to test if equalization was indeed free or if it was ``restricted'' to the same delay in all channels. One experiment measured binaural detection thresholds, using an adaptive procedure, for 1-, 5-, or 17-component tones against a broadband masking noise, in three binaural configurations (N0S180, N180S0, and N90S270). The thresholds for the 1-component stimuli were used to normalize the levels of each of the 5- and 17-component stimuli so that they were equally detectable. If equalization was restricted, then, for the 5- and 17-component stimuli, the N90S270 and N180S0 configurations would yield a greater threshold than the N0S180 configurations. No such difference was found. A subsequent experiment measured binaural detection thresholds, via psychometric functions, for a 2-component complex tone in the same three binaural configurations. Again, no differential effect of configuration was observed. An analytic model of the detection of a complex tone showed that the results were more consistent with free equalization than restricted equalization, although the size of the differences was found to depend on the shape of the psychometric function for detection.

  5. "Flashes in eyes" at Space Flight are the Signals that Retina is under "Hard" Affecting of Cosmic Charged Particles

    Trukhanov, Kirill

    "Flashes in eyes" at Space Flight are the Signals that Retina is under "Hard" Affecting of Cosmic Charged Particles K.A. Trukhanov SSC RF - Institute of bio-medical problems RAS, Moscow The report is dedicated to the further development of the hypothesis that seeming streak images are caused by a "hard" action of cosmic ions passing through the multilayer structure of retinal ganglion cell axons. It is suggested that the axons are exсited or are blocked by a passage of charged particles through the retina. The simplified mathematical model has been developed to establish a relation of an exposure conditions and visual images of streaks. The hypothesis explains many peculiarities of streaks remaining without any explanations in the literature. For example, it explains the horizontal orientation of streaks, the sensation (feeling) of fast moving ("spreading") of streaks, etc. The total cross-section of the axon manyfold exceeds cross-section of a photoreceptor. The damage of the multilayer axon structure is equivalent to the damage of the tens of thousands of photoreceptors. The offered mechanism is not linked to photobiological processes and does not demand complete dark adaptation for flash sensations. Taking into account composite processes of visual perception, the necessity of some adaptation time, naturally, remains. Thus, the developed hypothesis requires a specification of retinal damage estimations at long-term flight (for example, to Mars). It is interesting to note that there is the surprising similarity of a loss in the visual field (the scotomata) at traumata of retinal nerve fibers to visual images of some streaks. It is not inconceivable that the retina will turn out to be one of critical structures at long interplanetary flight. Thus, there is return to an idea which belongs to Prof. C.A. Tobias that the visual tract can be one of critical structures in relation to the space radiation. The cataractogenesis must be taken into account too.

  6. Direct Statistical Simulation of Astrophysical and Geophysical Flows

    Marston, B.; Tobias, S.

    2011-12-01

    Astrophysical and geophysical flows are amenable to direct statistical simulation (DSS), the calculation of statistical properties that does not rely upon accumulation by direct numerical simulation (DNS) (Tobias and Marston, 2011). Anisotropic and inhomogeneous flows, such as those found in the atmospheres of planets, in rotating stars, and in disks, provide the starting point for an expansion in fluctuations about the mean flow, leading to a hierarchy of equations of motion for the equal-time cumulants. The method is described for a general set of evolution equations, and then illustrated for two specific cases: (i) A barotropic jet on a rotating sphere (Marston, Conover, and Schneider, 2008); and (ii) A model of a stellar tachocline driven by relaxation to an underlying flow with shear (Cally 2001) for which a joint instability arises from the combination of shearing forces and magnetic stress. The reliability of DSS is assessed by comparing statistics so obtained against those accumulated from DNS, the traditional approach. The simplest non-trivial closure, CE2, sets the third and higher cumulants to zero yet yields qualitatively accurate low-order statistics for both systems. Physically CE2 retains only the eddy-mean flow interaction, and drops the eddy-eddy interaction. Quantitatively accurate zonal means are found for barotropic jet for long and short (but not intermediate) relaxation times, and for Cally problem in the case of strong shearing and large magnetic fields. Deficiencies in CE2 can be repaired at the CE3 level, that is by retaining the third cumulant (Marston 2011). We conclude by discussing possible extensions of the method both in terms of computational methods and the range of astrophysical and geophysical problems that are of interest.

  7. The evolution of the upright posture and gait—a review and a new synthesis

    NASA Astrophysics Data System (ADS)

    Niemitz, Carsten

    2010-03-01

    During the last century, approximately 30 hypotheses have been constructed to explain the evolution of the human upright posture and locomotion. The most important and recent ones are discussed here. Meanwhile, it has been established that all main hypotheses published until the last decade of the past century are outdated, at least with respect to some of their main ideas: Firstly, they were focused on only one cause for the evolution of bipedality, whereas the evolutionary process was much more complex. Secondly, they were all placed into a savannah scenario. During the 1990s, the fossil record allowed the reconstruction of emerging bipedalism more precisely in a forested habitat (e.g., as reported by Clarke and Tobias (Science 269:521-524, 1995) and WoldeGabriel et al. (Nature 412:175-178, 2001)). Moreover, the fossil remains revealed increasing evidence that this part of human evolution took place in a more humid environment than previously assumed. The Amphibian Generalist Theory, presented first in the year 2000, suggests that bipedalism began in a wooded habitat. The forests were not far from a shore, where our early ancestor, along with its arboreal habits, walked and waded in shallow water finding rich food with little investment. In contrast to all other theories, wading behaviour not only triggers an upright posture, but also forces the individual to maintain this position and to walk bipedally. So far, this is the only scenario suitable to overcome the considerable anatomical and functional threshold from quadrupedalism to bipedalism. This is consistent with paleoanthropological findings and with functional anatomy as well as with energetic calculations, and not least, with evolutionary psychology. The new synthesis presented here is able to harmonise many of the hitherto competing theories.

    Evidence is presented that the elastase-specific inhibitor of Mr 2500 (Sallenave, J.-M. & Ryle, A.P. (1991) Biol. Chem. Hoppe-Seyler 372, 13-21) is a biologically active fragment of a larger molecule described in the skin of patients with psoriasis (Wiedow, O., Shroder, J.-M., Gregory, H., Young, J.A. & Christophers, E. (1990) J. Biol. Chem. 265, 14791-14795) which the authors called elafin. We also describe the purification of the complete elafin molecule from bronchial secretions from a patient suffering from bronchial carcinoma, thus showing that the elafin, like the mucus proteinase inhibitor (MPI), is not of single origin but is probably a marker of inflammation (chronic obstructive pulmonary diseases, psoriasis...) present in different tissues.

    Considering Freudian and Post-Freudian approaches to the intersubjective Beatrice Ithier puts the work of Michel de M'Uzan and Thomas Ogden in comparison. To this comparison I add a consideration of the work of Christopher Bollas. The highly creative clinical approaches these three theorists take is shown to be informed by their elaborations of the Freudian notion of unconscious communication and by new approaches to the issue of identity. Attention is paid to differentiating traumatic from fanciful chimeras; and to the experience of the analyst undergoing the sorts of transformations requisite to entering this psychic space marked by fluid exchanges of being and becoming, wherein analyst becomes patient, new subjects are created through shared dreams, and through which monsters appear.

Biographical investigations were carried out on the clockmaker Nikolaus Lilienfeld, the astronomers Johann Wurzelbau, Friedrich Wilhelm Toennies and Boris Karpov as well as the “panbabylonist” Alfred Jeremias. Astronomers can be active also in poetry and fiction. This is shown in the studies of Johann Leonard Rost and Friedrich Wilhelm Bessel. Finally, Johannes Hevelius' Observatory in Danzig/Gdansk, destroyed by a fire in 1679, is reconstructed by means of printed sources, old maps and photographs.

    2014-01-01

    Who among us hasn’t fantasized about a diet that allows ingestion of a surfeit of calories that are burned off effortlessly by ramping up energy expenditure? In this issue of the JCI, research led by Christopher Morrison suggests that this dream may become a reality; however, a complete understanding of the molecular interface that connects nutrient choices with our cellular metabolism will be required. Laeger et al. show that the expression and secretion of the weight-reducing hormone fibroblast growth factor 21 (FGF21) is regulated by dietary proteins and not, as has been heretofore assumed, simply triggered by reduced caloric intake. This study not only sheds new light on the role of FGF21 in systems metabolism, but also on the ways our bodies cope with the ever-changing availability of different dietary macronutrients.

  13. A conflict of analysis: analytical chemistry and milk adulteration in Victorian Britain.

    PubMed

    Steere-Williams, Jacob

    2014-08-01

    This article centres on a particularly intense debate within British analytical chemistry in the late nineteenth century, between local public analysts and the government chemists of the Inland Revenue Service. The two groups differed in both practical methodologies and in the interpretation of analytical findings. The most striking debates in this period were related to milk analysis, highlighted especially in Victorian courtrooms. It was in protracted court cases, such as the well known Manchester Milk Case in 1883, that analytical chemistry was performed between local public analysts and the government chemists, who were often both used as expert witnesses. Victorian courtrooms were thus important sites in the context of the uneven professionalisation of chemistry. I use this tension to highlight what Christopher Hamlin has called the defining feature of Victorian public health, namely conflicts of professional jurisdiction, which adds nuance to histories of the struggle of professionalisation and public credibility in analytical chemistry.

    2003-04-01

    In 1985 Gerd Binnig and Calvin F. Quate from Stanford and Christopher Gerber from IBM (Zurich) designed the Atomic Force Microscope (AFM), since then a big interest arose around one of its main components; micromachined cantilevers. During all these years, authors have employed these tiny devices to sense multiple physical and chemical parameters through diverse transduction principles. Micromachined cantilevers offer many different transduction mechanisms: force sensing, bimetallic effect, mass loading, medium viscoelasticity, thermogravimetry, stress sensing, and more. Along with all these transduction mechanisms, a great variety of detection methods can be employed with cantilever-based sensors as for example: optical detection, resonance frequency measurement, piezoelectric integrated resistors, etc. The design and fabrication process of a micromachined Silicon capacitive gas sensor are described in this paper. Design and testing of the interface circuitry are also shown with preliminary results.

    In this article, I address the extent to which experts in bioethics can contribute to healthcare delivery by way of aid in clinical decision-making and policy-formation. I argue that experts in bioethics are moral experts, in that their substantive moral views are more likely to be correct than those of non-bioethicists, all else being equal, but that such expertise is of use in a relatively limited class of cases. In so doing, I respond to two recent arguments against the view that bioethicists are moral experts, one by Christopher Cowley and another by David Archard. I further argue that bioethics experts have significant additional contributions to make to healthcare delivery, and highlight a hitherto neglected aspect of that contribution: amelioration of moral misconception among clinicians. I describe in detail several aspects of moral misconception, and show how the bioethicist is in a prime position to resolve that sort of error. PMID:25256867

    2015-01-01

    The aim of this paper is to examine the iconography on a set of star charts by Albrecht Dürer (1515), and celestial globes by Caspar Vopel (1536) and Christoph Schissler (1575). The iconography on these instruments is conditioned by strong traditions which include not only the imagery on globes and planispheres (star charts), but also ancient literature about the constellations. Where this iconography departs from those traditions, the change had to do with humanism in the sixteenth century. This "humanistic" dimension is interwoven with other concerns that involve both "social" and "technical" motivations. The interplay of these three dimensions illustrates how the iconography on celestial charts and globes expresses some features of the shared knowledge and shared culture between artisans, mathematicians, and nobles in Renaissance Europe.

    Serendipity is a pleasant surprise of finding a particularly useful information while not looking for it. Significant historic events occurring as a result of serendipity include the discovery of the law of buoyancy (Archimedes principle) by the Greek mathematician Archimedes, of the Americas by Christopher Columbus and of gravity by Sir Isaac Newton. The role of serendipity in science has been immensely beneficial to mankind. A host of important discoveries in medical science owe their origin to serendipity of which perhaps the most famous is the story of Sir Alexander Fleming and his discovery of Penicillin. In the field of dermatology, serendipity has been responsible for major developments in the therapy of psoriasis, hair disorders, aesthetic dermatology and dermatosurgery. Besides these many other therapeutic modalities in dermatology were born as a result of such happy accidents. PMID:25814699

    Like watching a balloon borne by the breeze, a Lagrangian model tracks a parcel of air as it flows through the atmosphere. Whether running forward or backward in time, Lagrangian models offer a powerful tool for tracking and understanding the fates, or origins, of atmospheric flows. In the AGU monograph Lagrangian Modeling of the Atmosphere, editors John Lin, Dominik Brunner, Christoph Gerbig, Andreas Stohl, Ashok Luhar, and Peter Webley explore the nuances of the modeling technique. In this interview Eos talks to Lin about the growing importance of Lagrangian modeling as the world settles on climate change mitigation strategies, the societal value of operational modeling, and how recent advances are making it possible to run these complex calculations at home.

    Brown dwarfs inhabit a realm intermediate between the more massive stars and the less massive planets. Their thermal infrared emission is powered by the release of gravitational potential energy as regulated by their atmospheres. Long known only as theoretical constructs. the discovery of the first unimpeachable brown dwarf. Gliese 229 has opened up a new field: the study of brown dwarf atmospheres. The subsequent discoverv of numerous extrasolar giant planets circling nearby stars, further demonstrated the need for a comprehensive modeling effort to understand this new class of jovian atmospheres. Although no spectra are yet available of the new planets, the next generation of groundbased and spacebased telescopes will return such data. Here author report on the effort with Ames collaborator Dr. Christopher McKay to better understand these new atmospheres.

  8. The invention of atmosphere.

    PubMed

    Martin, Craig

    2015-08-01

    The word "atmosphere" was a neologism Willebrord Snellius created for his Latin translation of Simon Stevin's cosmographical writings. Astronomers and mathematical practitioners, such as Snellius and Christoph Scheiner, applying the techniques of Ibn Mu'ādh and Witelo, were the first to use the term in their calculations of the height of vapors that cause twilight. Their understandings of the atmosphere diverged from Aristotelian divisions of the aerial region. From the early years of the seventeenth century, the term was often associated with atomism or corpuscular matter theory. The concept of the atmosphere changed dramatically with the advent of pneumatic experiments in the middle of the seventeenth century. Pierre Gassendi, Walter Charleton, and Robert Boyle transformed the atmosphere of the mathematicians giving it the characteristics of weight, specific gravity, and fluidity, while disputes about its extent and border remained unresolved.

    As the world prepares to celebrate the quincentennial events surrounding the discovery of the New World by Christopher Columbus in 1492, a particular interest regarding the influence of epidemic infectious diseases on the history of the conquest of America has emerged. Contrary to popular belief, it was not the European guns or fierce soldiers that conquered the native Americans, but instead it was the common childhood illnesses brought from the Old World by the European conquistadors. Diseases such as smallpox, measles, and typhus annihilated most of the American native populations. Devastating epidemics resulted throughout the New World. We will review the consequences of introducing new infectious agents into a nonimmune population, discuss the major pathogens that were imported from the Old World, and focus on how these diseases may have affected the aboriginal depopulation of the Americas.

    2015-07-01

    This paper focuses on the horse pinworm, Oxyuris equi, in archaeology during the Holocene period, and presents an overview of past published occurrences, early mentions in texts, and new data from our paleoparasitology research. This original compilation shows that the most ancient record of the horse pinworm dates to ca. 2500 years before present (ybp) in Central Asia and to ca. 2020 ybp in Western Europe. It also shows that the parasite is not detected on the American continent until contemporary periods. The role of European migrations from 1492 (Christopher Columbus) is discussed to explain the transfer of the horse pinworm from the Old World to the Americas. The absence of any record of this parasite before ca. 2500 ybp in Eurasia could be explained by parasite ecology, unfavorable sampling and scarcity of horse archeological remains. For the Americas, the absence of horse for long periods can be an additional explanation for the absence of the parasite. PMID:25916688

  14. Pre-Columbian treponemal disease from 14th century AD Safed, Israel, and implications for the medieval eastern Mediterranean.

    PubMed

    Mitchell, Piers D

    2003-06-01

    In 1912, 68 medieval crania were excavated from a cave at Safed in the eastern Mediterranean and brought to the United Kingdom. It is only recently that these skulls have been studied for evidence of disease. One adult individual demonstrates multiple lesions of the cranial vault, compatible with treponematosis. Radiocarbon dating suggests the year of death to be between 1290-1420 AD. This range equates to the mamluk period, just after the crusades. This is the oldest dated case of treponematosis in the Middle East, and the first to confirm its presence there before the epidemiologically important transatlantic voyage of Christopher Columbus. The finding has significant implications for our understanding of the introduction of the disease to the Middle East and of the medieval diagnosis of ulcerating skin conditions by medical practitioners in the Mediterranean world.

    Since the publication in this journal of our two articles on the end of Andreas Vesalius' life, some very old sources have recently become available that we were unable to consult at the time of writing and that now prompt us to add a coda. These sources give an even better picture of both the circumstances of the disaster that led to Vesalius' death and the correct site of his burial. Firstly, there is a text by Reinerus Solenander that casts a completely different light on the circumstances in which his ship was at sea and the way in which it reached land; in addition, there is a new early eye-witness report of his burial-place by Christoph Fürer von Haimendorf, dating from 6 August 1565.

    As Earth's climate warms, agricultural producers will need to adapt. Changes, especially increases in extreme events, are already having an impact on food production, according to speakers at a 1 May session on agriculture and food security at the AGU Science Policy Conference. Christopher Field, director of the Department of Global Ecology at the Carnegie Institution for Science of Washington, D. C., pointed out the complex factors that come into play in understanding food security, including spatially varying controls and stresses, incomplete models, and the potential for threshold responses. Factors that are likely to cause problems include increasing population; increasing preference for meat, which needs more land and energy inputs to produce; climate change; and increasing use of agricultural lands for biomass energy.

  20. Influence of plant abundance on nectar feeding by Aedes aegypti (Diptera: Culicidae) in southern Mexico.

    The availability of flowering plants affected the sugar feeding rates of female Aedes aegypti (L.) in 4 areas of a small city in southern Mexico. The proportion of mosquitoes containing sugar varied from 8 to 21% in 4 areas in direct relation to blooming plant abundance. Human density was similar in the 4 areas (range, 3.9-5.4 per house), whereas the number of flowering plants per house increased on the outskirts (range, 3.1-5.4 plants per house). Equal proportions of sugar positive females were nulliparous or parous, indicating similar sugar feeding at any age. In addition, nearly 60% of positive females were at the Christophers stage II, indicating a greater need for flight fuel during the early stages of egg development. We conclude that Ae. aegypti feeds frequently on nectar and that this activity is modulated by nectar availability. PMID:9439110

  1. History of femoral head fracture and coronal fracture of the femoral condyles.

    PubMed

    Bartoníček, Jan; Rammelt, Stefan

    2015-06-01

    The first known description of the coronal fracture of the lateral femoral condyle was published by Busch in 1869. Hoffa used Busch's drawing in the first edition of his book in 1888 and accompanied it only with one sentence. A full case history of this fracture pattern was described by Braun in 1891. However, Braun's article fell into oblivion and so the fracture was popularized only in the fourth edition of Hoffa's textbook, particularly thanks to the drawing, rather than the brief description. Therefore, a fracture of the posterior femoral condyle, or more specifically, of the lateral condyle, could properly be called "Busch-Hoffa fracture". Femoral head fracture was initially described by Birkett in 1869. Of essential importance in this respect were the publications by Christopher in 1924 and, particularly, Pipkin's study of 1957, including his classification that is still in use today. A historically correct eponym for a femoral head fracture would therefore be "Birkitt-Pipkin fracture". PMID:25787681

    BRUSSELS, BELGIUM-High-energy physicists' current explanation for the behavior of subatomic particles and forces, known as the Standard Model, is doing just fine. That was the take-home message for the 800 delegates who gathered here from 27 July to 2 August for the International Europhysics Conference on High-Energy Physics. "Mainly this was a conference of consolidation, steady progress, many very beautiful and detailed results," Christopher Llewellyn Smith, director general of CERN, the European particle physics laboratory, told Science. But while a multitude of presentations described ever more accurate tests and confirmations of the model, physicists also discussed hints that a whole new range of phenomena beyond the Standard Model is lurking just above the energies of current accelerators-and within range of the next generation of experiments.

    Self-propelling fluidic devices naturally result from some asymmetry of wettability, geometry or temperature. Here we consider the case of motions arising from the air around, forced by some trick to flow in an asymmetric way. We first consider vapor flows generated in a Leidenfrost situation, and made anisotropic by textures decorating the hot substrate. We discuss how the force and speed arising from these rectified vapor flows can be optimized. Then, we observe drops on a fiber placed in a symmetric wind. In a well-defined window of wind speed, the drop is found to self-propel along the fiber, which is analyzed. We also show that this effect makes drops moving in opposite direction bounce on each other, which generates fascinating 1-D dynamics.

    Expertly written and lavishly illustrated, The Cambridge Illustrated History of Astronomy offers a unique account of astronomical theory and practice from antiquity to the present day. How did Moslems of the Middle Ages use astronomy to calculate the direction of Mecca from far-flung corners of the Islamic world? Who was the only ancient Greek to suspect that the earth might revolve around the sun? How did Christopher Columbus abuse his knowledge of a lunar eclipse predicted by an astronomical almanac? Packed with anecdotes and intriguing detail, this book describes how we observed the sky and interpreted what we saw at different periods of history; how this influenced our beliefs and mythology; and how great astronomers contributed to what we now know. The result is a lively and highly visual history of astronomy - a compelling read for specialists and non-specialists alike.

    Although 97%-98% of the climate researchers most actively publishing in the field accept the basic tenets of the Intergovernmental Panel on Climate Change's (IPCC) findings [Anderegg et al., 2010], there is a consistent undercurrent of doubt among the general public (A. Leiserowitz et al., Global warming's six Americas in May 2011, online report, 57 pp., Yale Project on Climate Change Communication, Yale University, New Haven, Conn., 2011). To some extent, this doubt is fueled by high-profile climate change deniers who offer "the real view" of climate science [Oreskes and Conway, 2010].

Buckley (ApJ, 496, 292 [1998]), we have identified an error in the calculation of the uncertainties in the centroid velocity of line profiles. With the correct formula presented here, the uncertainties of the centroid velocity of observed line profiles are reduced from those originally reported. The conclusions of the original paper are unchanged. The new uncertainties σ in km s-1 (col. [5] of Table 2) are 0.01, 0.01, 0.01, 0.02, 0.01, 0.01, 0.01, 0.12, 0.06, and 0.01.

    The work of one of the greatest writers of German Romanticism, E.T.A. Hoffmann, incorporates a great deal of current medical knowledge, which Hoffmann used in a skillful and detailed manner in the portrayal of his characters and their motives. Immersed as he was in contemporary medical practice, an interest fuelled by his own deep-seated hypochondria, he was particularly taken with the works of Philippe Pinel, Johann Christoph Reil, Carl A.F. Kluge, and Gotthelf Heinrich Schubert, who were all interested in the working of the mind. This article demonstrates how attention to Hoffmans's medical reading list offers insights useful for critical understanding of his work, using as an example the analysis of the mad goldsmith Cardillac in one of Hoffmann's most famous stories, 'Das Fräulein von Scuderi'.

    Immediately following the Boston Marathon attacks, individuals near the scene posted a deluge of data to social media sites. Previous work has shown that these data can be leveraged to provide rapid insight during natural disasters, disease outbreaks and ongoing conflicts that can assist in the public health and medical response. Here, we examine and discuss the social media messages posted immediately after and around the Boston Marathon bombings, and find that specific keywords appear frequently prior to official public safety and news media reports. Individuals immediately adjacent to the explosions posted messages within minutes via Twitter which identify the location and specifics of events, demonstrating a role for social media in the early recognition and characterization of emergency events. *Christopher Cassa and Rumi Chunara contributed equally to this work.

    In 1761 the French scholar and Sinologue Joseph de Guignes announced that "Chinese vessels made the voyage to America many centuries before Christopher Columbus." From the Chinese books in the Bibliotheque du Roi and new missionary reports from Beijing, he concluded that the mythical land of Fusang described by a medieval Buddhist monk could be nowhere other than the west coast of North America, only recently charted by European navigators. Philippe Buache, premier géographe du roi, agreed. At the height of the French Enlightenment, the indigenous geographical tradition of China could be used to further the progress of universal science, providing evidence about issues from the mapping of the Pacific Rim to the organization of the continents. Furthermore, the story of Fusang explained the origins of American peoples, showing that the inhabitants of the New World had arrived there from the Old and contributing to a diffusionist account of the development of civilization in space and time.

  14. Clippers or the knife? The reform of surgical practice and the difficulty of early wound closure.

    Salt, vinegar and wine sounds more like a recipe from the Saturday kitchen, but in 1667 it was all a surgeon could use to close wounds, along with silk and linen strips. In providing this service, barbers and surgeons found themselves confused and intertwined, struggling for professional recognition that was about to experience reform. Allegations of neglect in the aftermath of a major seafaring battle on the very shores of our capital city required the court of King Charles II to search for a solution of supreme magnitude to accommodate the hundreds of maimed sailors who were littering the streets of London. A campaign to conceal the horrors of warfare began which lead to the implementation of the Greenwich charter and the construction of a hospital which the architect Christopher Wren helped to design.

  15. Sexual differentiation of monoaminergic neurons--genetic or epigenetic?

    It is currently believed that sexual differentiation of the brain is mediated entirely by the epigenetic action of gonadal steroids during a critical period of development. Ingrid Reisert and Christoph Pilgrim review sexual dimorphisms of monoaminergic systems, which also appear to be generated by sex steroids. However, there are a number of observations that are not explainable by the 'androgen theory of sexual differentiation'. Results obtained from cultures of embryonic rat brain tissue appear to indicate that dopaminergic neurons may develop morphological and functional sex differences in the absence of sex steroids. Hormone-independent and -dependent developmental processes may affect diencephalic and mesencephalic dopaminergic neurons in a regionally diverse fashion. Factors other than sex steroids need to be examined. It is possible that some sexual dimorphisms in the nervous system may develop under primary genetic control. PMID:1722367

    Materials exhibiting superconductivity above liquid nitrogen temperatures (77 K) will enable new applications of this phenomena. One of the first commercial applications of this technology will be superconducting magnets for medical imaging. However, a large number of aerospace applications of the high temperature superconducting materials have also been identified. These include magnetic suspension and balance of models in wind tunnels and resistanceless leads to anemometers. The development of superconducting wires fabricated from the ceramic materials is critical for these applications. The progress in application of a patented fiber process developed by Clemson University for the fabrication of superconducting wires is reviewed. The effect of particle size and heat treatment on the quality of materials is discussed. Recent advances made at Christopher Newport College in the development of micro-ohm resistance electrical contacts which are capable of carrying the highest reported direct current to this material is presented.

    Christoph Wilhelm Hufeland (1762-1836) was one of the eminent physicians at the time of Goethe. When only 21 years old, he followed his father as a medical practitioner in Weimar. In 1793 he became Professor of Medicine at the University of Jena, from where he moved, in 1801, to Berlin as the physician in ordinary to king Friedrich Wilhelm III, council of state, and Professor at the leading hospital, the Charité. Hufeland pioneered in what today would be called public hygiene. Many of his lectures and publications were addressed to the educated laymen. In his most read book, the 'Makrobiotik', he emphasizes the importance of the 24-h periodicity as a basic unit of biological chronometry. In view of this, Hufeland has become a kind of 'patron saint' to modern chronobiologists. PMID:1760962
