    1999-01-01

    George Wald was born in 1906 in New York City to immigrant parents. An early and voracious reader, he soon developed a wide range of interests and entered New York University as a pre-law student, the first in his family to attend college. Shortly shifting to pre-medicine, he graduated college in biology. For graduate work, he joined the laboratory of Selig Hecht, a pioneer in vision research, at Columbia University. In 1932, four months before Hitler came to power, George went to Berlin to do postdoctoral work in the laboratory of Otto Warburg and there found vitamin A in the retina. This launched his life-long explorations of the molecular basis of vision for which he received the Nobel Prize in Physiology or Medicine in 1967. During the 1960s, George became increasingly involved in anti-war and anti-nuclear activities, writing and travelling widely, including multiple trips to commemorations of the bombings of Hiroshima and Nagasaki sponsored by Japanese colleagues. He considered these activities part of being a biologist, someone concerned with life. In his final years, he turned to questions about consciousness, writing and speaking about 'Life and Mind in the Universe'. PMID:10614043

    Pustylnik, I.

    We discuss some of the rich scientific legacy of George Gamov, an outstanding figure in physics and cosmology of the XXth century, whose talent has bridged the gap between East and West long before the decline of totalitarian system. Our analysis is based partly on Gamow's original scientific and popular papers, partly on the reminiscences of his colleagues and contemporaries (among other, R. A. Alpher, S. M. Ulam, A. A. Penzias, M. Delbruck). We discuss how these different facets of Gamow's rare talent are reflected in his transparent physical models and confront some of his predictions with the realities of contemporary extragalactic and observational cosmology.

    tuneable lasers, generally with the emphasis on understanding the underlying physics rather than accumulating data. He had a highly original mind, which showed both in his choice of research topics and in his method of approach. He did not follow fashion; his instinct for an interesting problem was at odds with the modem policy of direct funding and the identification of "growth areas". His applications for research grants were often unsuccessful, despite his high international standing and integrity. He was never interested in building up a large research team, and had comparatively few research students, but his enthusiasm and commitment to the quality of his science attracted a succession of overseas visitors to his laboratory. Following my own year at the Clarendon, and some subsequent visits both to Oxford and to Reading, there was a continuing strong association between the Clarendon and Otago Physics that continues until today. George Series was the William Evans Visiting Professor to Otago University in 1972. He never lost his interest in the fundamentals of physics inspired by his first researches into the structure of the hydrogen atom; he wrote on the Rydberg constant, the physics of spontaneous emission, and on the fine-structure constant α = e2/hc. He donated a garden seat to St Edmund Hall (Oxford), of which he was a Fellow. On it he placed a plaque* in recognition of the ubiquitous nature of this constant; it almost had magical significance for him. He served physics in many ways outside research. He was for a number of years the Editor of the European Journal of Physics and was also Editor of the Journal of Physics B: Atomic and Molecular Physics, He was also on the Editorial Board of a number of journals. He was elected to Fellowship of a number of physics societies. The Editorial Board of these Memorial Essays dedicate them to George's memory, and to his wife Annette and his family.

    This mosaic was made from frames acquired by the microscopic imager on NASA's Mars Exploration Rover Spirit during Spirit's 1,031 Martian day, or sol, on the red planet (Nov. 27, 2006). It shows a rock target called 'King George Island' after the target was brushed by the rover's rock abrasion tool. The mosaic covers approximately 6 centimeters (2.4 inches) across and shows the granular nature of the rock exposure. The grains are typically about 1 millimeter (.04 inches) wide. Data from the rover's Moessbauer spectrometer provides evidence that they have an enhanced amount of the mineral hematite relative to surrounding soils.

  15. Dedicated Deployable Aerobraking Structure

    NASA Technical Reports Server (NTRS)

    Giersch, Louis R.; Knarr, Kevin

    2010-01-01

    A dedicated deployable aerobraking structure concept was developed that significantly increases the effective area of a spacecraft during aerobraking by up to a factor of 5 or more (depending on spacecraft size) without substantially increasing total spacecraft mass. Increasing the effective aerobraking area of a spacecraft (without significantly increasing spacecraft mass) results in a corresponding reduction in the time required for aerobraking. For example, if the effective area of a spacecraft is doubled, the time required for aerobraking is roughly reduced to half the previous value. The dedicated deployable aerobraking structure thus enables significantly shorter aerobraking phases, which results in reduced mission cost, risk, and allows science operations to begin earlier in the mission.

  18. Superstitions of George Bartisch.

    Blanchard, Donald L

    2005-01-01

    George Bartisch was a 16th century German ophthalmologist who published the first ophthalmology textbook in the vernacular for laymen and non-university-trained practitioners. His treatments and understanding of diseases rested firmly on Greek tradition, but he also was very involved in the superstitions of the day. This essay looks at the man and his mores. Bartisch believed that much of the suffering of patients had to do with sins they had committed, and that the devil was the active force in the world inflicting this punishment. Often, he believed, witches would carry out the devil's hexes, in the form of either hot or cold witchcraft. Bartisch also felt that astrology played a major role in the outcome of surgery. Because of that he practiced only during certain astrological signs, and in the proper waxing and waning phases of the moon. He also linked many common problems to sins. For example, presbyopia was presented as due to excessive use of alcohol. Glasses were to be avoided because he felt they destroyed vision in themselves. Despite these superstitions and misconceptions, Bartisch was an honorable professional and his books give insight into the making of a good ophthalmologist. PMID:16139042

    G. N. Papanicolaou was born on May the 13, 1883 in the city of Kymi on the Greek island of Euboea. He received his MD degree from the University of Athens in 1904 and a PhD from the University of Munich in 1910. After service as a medical officer in the Balkan War of 1912-1913, he came to New York with Mary (for over 50 years Dr Pap's life companion). George's violin playing at restaurants and coffee-shops supplied them with a few extra cents. Papanicolaou was appointed assistant in the Pathology Laboratory at the New York Hospital. In 1928 he presented his work "New Cancer Diagnosis" to the third race betterment conference (Battle Creek, Michigan). But the work was met with scepticism. The now famous monograph "The Diagnostic Value of Vaginal Smears in Carcinoma of the Uterus" was published in 1941 in the Am J Obst Gyn. During this time, he developed his method of preservation of these cells by wet fixation and precise staining. Papanicolaou persisted with his ideas, and finally cytologic examination of the cervix was accepted. The power of Papanicolaou screening for uterine cancer was remarkable. The first National Cytology Congress, held in 1948, hailed this new diagnostic tool for carcinoma of the cervix as unique because it could detect cancer before it was visible. He described the importance of a distinct cellular pattern corresponding to cervical intraepithelial neoplastic lesions. The value of this pattern, expressing evolutionary steps in the development of cancer at individual cell levels, was not appreciated.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8278086

    Photo of Susan L Greenblatt Figure 1. Susan in May, 1994 This volume is dedicated to the memory of Susan L Greenblatt, the wife of Steven L Guberman. Susan attended 6 of the 8 dissociative recombination (DR) meetings. Her advice and wise counsel played a vital role in the organization of several of these meetings. The fifth meeting in Chicago in 2001 was her idea and it would not have occurred without her encouragement. Susan was always amused by the memory of the first group dinner at the second DR meeting at St Jacut in 1992. As we went around the dinner table identifying ourselves, it soon became her turn. Susan was a sociologist and after introducing herself she said: "I am not a chemist". A spontaneous chorus of attendees proclaimed "Neither are we!". Her husband and a few other chemists abstained. In 1983, Susan and I established the Institute for Scientific Research (ISR). The name was chosen so as to span sociology and chemical physics. Four years prior, an ophthalmologist had diagnosed a rare retinal condition of unknown origin and advised her to change her profession to one that did not involve reading. (She was able to read for the rest of her life.) Twenty years later we learned that the cause of the retinal and all her other health problems was a recently discovered rare mitochondrial mutation. Her experience with ophthalmologists and her life-long keen sense of injustice, led her to write a grant proposal to the US Department of Education to survey all ophthalmologists in the US to determine whether they were aware of and whether they told their patients about resources and aids that could help them to continue reading and participating in everyday activities. As part of the grant and based upon the survey results, she proposed to set up low-vision training programs for ophthalmology residents. We knew that the competition for funding was intense and included several well-known and more established organizations. Nevertheless, the proposal was funded

    Gamov, I. L.

    It is quite interesting and flattering for an economist to publish a paper in such a prominent astronomical journal. And taking into account the fact that the author is a relative of the great cosmologist of the 20th century does not diminish but, vice versa, increases the piquancy of the appearance of this article. You may agree, dear readers, that it is fairly difficult to avoid a temptation of addressing you on behalf of numerous admirers of George Gamow's talent, as well as of supporters of the Gamow Foundation of Moldova. Frankly speaking, I cannot get rid of a feeling that George Gamow himself, through some genetic "channels" known to him alone, is pushing me to tell about him, for he was famous for all kinds of tricks.

    We present a prototype of a scalable computing cloud. It is intended to be deployed on the basis of a cluster without the separate dedicated storage. The dedicated storage is replaced by the distributed software storage. In addition, all cluster nodes are used both as computing nodes and as storage nodes. This solution increases utilization of the cluster resources as well as improves fault tolerance and performance of the distributed storage. Another advantage of this solution is high scalability with a relatively low initial and maintenance cost. The solution is built on the basis of the open source components like OpenStack, CEPH, etc.

  5. Georges Bank Winds: 1975 19971

    NASA Astrophysics Data System (ADS)

    Manning, James; Strout, Glenn

    Twenty-three years (1975-1997) of anemometer records from the four NOAA buoys located near Georges Bank are examined. While the individual buoy records have occasional gaps due to instrument breakdowns and the buoys deployments were limited to certain years, the combination of the four buoys provides a nearly continuous series of observed wind. After correcting for different anemometer heights, sea-surface wind stress is calculated by the neutral stability method of Large and Pond J. Phys. Ocean 11 (1981) 324. Weekly mean stress is plotted for the entire period. Significant coherence (0.72-0.92) was found between sites with very little phase or gain for the 2-10 day storm-band period. An offshore increase of ˜0.006 Pa/100 km is detected in the mean stress for the Winter/Fall seasons. The complex correlation coefficients (calculated as a single measure of coherence across all frequency bands) ranges from 0.68 to 0.90. Other sources of wind data are discussed including the Fleet Numerical Meteorology and Oceanography Center's (FNMOC) estimates from pressure observations, the Comprehensive Ocean Atmosphere Data Set (COADS) from ship observations, and NOAA's National Center for Environmental Prediction (NCEP) recent model/data assimilation. For purposes of representing storm-band frequency, the FNMOC winds account for more than 80% of the variability in the buoy record and they provide a continuous surface wind estimate for the Georges Bank region back to 1967. However, the intensified wind stress as a function of distance offshore, as detected by both the buoys and COADS , is not detected in the FMNOC records. Also, a counterclockwise rotation of 19 max° is needed (in addition to the standard 15°) to correct the FMNOC winds for the atmospheric boundary layer. Recent NCEP products provide a finer scale spatial coverage of the wind field and are a potential source of boundary forcing for coastal ocean circulation models.

    George Washington Crile was a successful surgeon who lived at the end of the 19th century. He was born on 11 November 1864 on a farm near Chili, Ohio. He became interested in the study of shock after a close friend died from hemorrhage. Crile dedicated his research years to the study of shock, cardiac arrest, and the use of adrenaline. His research on shock and cardiac arrest led to treatment guidelines that are still used today. He also participated in the Spanish-American War and in World War I as a Navy Surgeon and saved the lives of many soldiers with his principles of blood transfusion and sanitation. He is also known in the surgical world as the grandfather of radical neck dissection and received the Gold Lannelongue Medal and prize. Having written over 400 papers and 24 books, George W. Crile died from complications of bacterial endocarditis on 7th January 1943.

  8. George Combe and common sense.

    PubMed

    Dyde, Sean

    2015-06-01

    This article examines the history of two fields of enquiry in late eighteenth- and early nineteenth-century Scotland: the rise and fall of the common sense school of philosophy and phrenology as presented in the works of George Combe. Although many previous historians have construed these histories as separate, indeed sometimes incommensurate, I propose that their paths were intertwined to a greater extent than has previously been given credit. The philosophy of common sense was a response to problems raised by Enlightenment thinkers, particularly David Hume, and spurred a theory of the mind and its mode of study. In order to succeed, or even to be considered a rival of these established understandings, phrenologists adapted their arguments for the sake of engaging in philosophical dispute. I argue that this debate contributed to the relative success of these groups: phrenology as a well-known historical subject, common sense now largely forgotten. Moreover, this history seeks to question the place of phrenology within the sciences of mind in nineteenth-century Britain.

    Fifty years have passed since the death of Dr George Nicholas Papanicolaou, who was born in Kyme at the island of Euboea in Greece in 1883 and became known for his innovative revolutionary invention of the Pap smear test performed at the Cornell University Medical College in the USA. To date, even after the introduction of HPV vaccination into the clinical practice, Dr George Papanicolaou's method remains an essential component of the prevention strategy against cancer and has resulted in a 70% decrease in cervical cancer mortality over the last 60 years. This article, which presents briefly his biography, is dedicated to him on the occasion of the 50th anniversary of his death.

  9. Twisting and Writhing with George Ellery Hale

    NASA Astrophysics Data System (ADS)

    Canfield, Richard C.

    2013-07-01

    Early in his productive career in astronomy, George Ellery Hale developed innovative instrumentation that allowed him to image the magnetically-dominated solar chromosphere. Among the solar phenomena he discovered were sunspot vortices, which he attributed to storms akin to cyclones in our own atmosphere. Much more recently, physicists discovered a quantity that is very well conserved in ideal magnetohydrodynamics: magnetic helicity. Our contemporary understanding of Hale's vortices as a consequence of large-scale twist in sunspot magnetic fields hinges on this conservation. I will review the crucial role that this property plays in the hemispheric and solar cycle dependences of Hales vortices, as well as solar flares and CMEs.

    The history of medicine can give insights into past achievements and provide knowledge and even inspiration, a valuable commodity for young students and all doctors. The contribution of Alcuin of York to basic education, and its appreciation by Sir George Newman, medical officer of health and first Chief Medical Officer of the UK in 1919, is recalled. Newman's Quaker education at Bootham School, his views on the main principles of such an education, as well as his influence on its establishment are summarised. A liberal education for doctors is important and knowledge and inspiration from the past may be one factor in enhancing morale.

  11. George Eliot's interrogation of physiological future knowledge.

    PubMed

    Claggett, Shalyn

    2011-01-01

    This essay tracks George Eliot's sustained interest in the epistemological problems surrounding the Victorian tendency to envision the future through the body's materiality. It argues that her nuanced criticism of phrenology in "The Lifted Veil" (1859) and "A Minor Prophet" (1865) addresses the delimiting psychological and social effects that attend an applied theory of physiological determinism. Returning to this problem in Daniel Deronda (1876), Eliot offers Mordecai's plan to posit Deronda's body as a living emblem as a radical alternative to racial iconography and typological meaning—a move that allowed her to reconcile the body's legibility with a future beyond socially inscribed possibilities.

    Two thousand nine hundred kilometers of minisparker data were collected on Georges Bank by the United States Geological Survey during October of 1975. Several sedimentary features have been observed in the data, The bank is recognized as a compound feature resulting from erosion of Tertiary coastal-plain strata followed by deposition of an extensive sediment wedge on the western flank of the cuesta. Marine planation (probably Late Pleistocene) truncated this bank morphology producing an erosion surface roughly paralleling the present sea floor. The truncated bank surface is blanketed by a veneer of complex Late Pleistocene drift which masks underlying features and is being reworked by modern processes. Present bank morphology is inferred-to be arather recent development. A proper understanding of the significance of complex bank sediments with respect to the potential geologic hazards of drilling or placement of bottom. supported structures necessitates a more detailed seismic reflection program, in conjunction with geotechnical analysis of core-samples.

  7. Georges Sagnac: A life for optics

    NASA Astrophysics Data System (ADS)

    Darrigol, Olivier

    2014-12-01

    Georges Sagnac is mostly known for the optical effect in rotating frames that he demonstrated in 1913. His scientific interests were quite diverse: they included photography, optical illusions, X-ray physics, radioactivity, the blue of the sky, anomalous wave propagation, interferometry, strioscopy, and acoustics. An optical theme nonetheless pervaded his entire œuvre. Within optics, an original theory of the propagation of light motivated most of his investigations, from an ingenious explanation of the Fresnel drag, through the discovery of the Sagnac effect, to his quixotic defense of an alternative to relativity theory. Optical analogies efficiently guided his work in other domains. Optics indeed was his true passion. He saw himself as carrying the torch of the two great masters of French optics, Augustin Fresnel and Hippolyte Fizeau. In this mission he overcame his poor health and labored against the modernist tide, with much success originally and bitter isolation in the end. xml:lang="fr"

  8. George Engel's Epistemology of Clinical Practice.

    PubMed

    Saraga, Michael; Fuks, Abraham; Boudreau, J Donald

    2014-01-01

    George Engel's (1913-1999) biopsychosocial model, one of the most significant proposals for the renewal of medicine in the latter half of the 20th century, has been understood primarily as a multi-factorial approach to the etiology of disease and as a call to re-humanize clinical practice. This common reading of Engel's model misses the central aspect of his proposal, that the biopsychosocial model is an epistemology for clinical work. By stating the simple fact that the clinician is not dealing directly with a body, but first, and inevitably, with a person, Engel challenged the epistemology implicit in the classical clinical method-a method predicated on the possibility of direct access to the body. Framed in epistemological terms, the issue at stake is not the need to complement medical science with humane virtues, but rather to acknowledge that the object of clinical practice is not the body but the patient.

  9. Hans Georg Trüper (1936-2016) and His Contributions to Halophile Research.

    2016-05-12

    Prof. Hans Georg Trüper, one of the most important scientists in the field of halophile research, passed away on 9 March 2016 at the age of 79. I here present a brief obituary with special emphasis on Prof. Trüper's contributions to our understanding of the halophilic prokaryotes and their adaptations to life in hypersaline environments. He has pioneered the study of the halophilic anoxygenic phototrophic sulfur bacteria of the Ectothiorhodospira-Halorhodospira group. Some of the species he and his group isolated from hypersaline and haloalkaline environments have become model organisms for the study of the mechanisms of haloadaptation: the functions of three major organic compounds - glycine betaine, ectoine, and trehalose - known to serve as "compatible solutes" in halophilic members of the Bacteria domain, were discovered during studies of these anoxygenic phototrophs. Prof. Trüper's studies of hypersaline alkaline environments in Egypt also led to the isolation of the first known extremely halophilic archaeon (Natronomonas pharaonis). The guest editors dedicate this special volume of Life to the memory of Prof. Hans Georg Trüper.

  1. George Darwin lecture: The expansion rate of the universe

    Freedman, Wendy

    2002-02-01

    Wendy Freedman presents the 2001 George Darwin Lecture on present and future advances in cosmology. Modern cosmology is undergoing an explosion of observational and experimental results that is in turn driving significant theoretical advances and a dynamic interface between theory and experiment. As a consequence, cosmological parameters are becoming much more precisely constrained. In this, the George Darwin lecture for 2001, I look back at the some of the advances made since Edwin Hubble presented his George Darwin lecture in 1953, and look ahead to the resolution of significant cosmological uncertainties.

    We report on upper limb anomalies in two children with a complete DiGeorge sequence: conotruncal defects, hypocalcemia, thymic aplasia, and facial anomalies. One child had preaxial polydactyly, and the other had club hands with hypoplastic first metacarpal. In both patients, molecular analysis documented a 22q11 deletion. To our knowledge, limb anomalies have rarely been reported in DiGeorge syndrome, and they illustrate the variable clinical expression of chromosome 22q11 deletions. 13 refs., 2 figs.

    2007-01-01

    This Web site contains Lidar-derived topography (first return and bare earth) maps and GIS files for George Washington Birthplace National Monument in Virginia. These lidar-derived topography maps were produced as a collaborative effort between the U.S. Geological Survey (USGS) Coastal and Marine Geology Program, FISC St. Petersburg, the National Park Service (NPS), Northeast Coastal and Barrier Network, Inventory and Monitoring Program, and the National Aeronautics and Space Administration (NASA) Wallops Flight Facility. One objective of this research is to create techniques to survey coral reefs and barrier islands for the purposes of geomorphic change studies, habitat mapping, ecological monitoring, change detection, and event assessment. As part of this project, data from an innovative instrument under development at the NASA Wallops Flight Facility, the NASA Experimental Airborne Advanced Research Lidar (EAARL) are being used. This sensor has the potential to make significant contributions in this realm for measuring subaerial and submarine topography wthin cross-environment surveys. High spectral resolution, water-column correction, and low costs were found to be key factors in providing accurate and affordable imagery to coastal resource managers.

  5. [Heinrich Georg Bronn and Origin of Species].

    PubMed

    Junker, T

    1991-01-01

    Heinrich Georg Bronn, one of the leading nineteenth-century palaeontologists was also known as the translator of Charles Darwin's Origin of Species. He undertook his translation soon after the publication of Darwin's work and added a critical post-scriptum. Still in 1857 Bronn had written unambiguously in favour of the constancy of biological species. After the publication of the Origin of Species he thought that in spite of a number of objections which could be brought forward, the future belonged to Darwin's theory and supported with great commitment its spreading. It is puzzling that Bronn did so when he was almost 60 and committed to a religious outlook. The history of the reception of Darwin's doctrine shows that, as a rule, older scientists with such religious worldviews would not support Darwin. The analysis of Bronn's earlier writings and the correspondence between Darwin and Bronn will throw light on the reasons why he represented an exemption. Bronns opinion of Darwin's theory shows the wide gap between the older typologically-inclined natural history and Darwin's evolutionary theory. To conclude, Bronn's translation of the Origin of Species as well as his post-scriptum were of considerable importance for the reception of Darwin's ideas in the german-speaking world.

    Presents an obituary for George A. Miller (1920-2012). Miller ranks among the most important psychologists of the 20th century. In addition to writing one of the best known papers in the history of psychology ("The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information," published in Psychological Review in 1956), Miller also fomented the cognitive revolution, invented psycholinguistics and cognitive psychology, imported powerful ideas from the theories of information, communication, grammar, semantics, and artificial intelligence, and left us a sparkling oeuvre that proves that a rigorous scientist needn't write in soggy prose. Honors rained down on Miller. APA gave him the Award for Distinguished Scientific Contributions (1963), the American Psychological Foundation Gold Medal Award for Life Achievement in Psychological Science (1990), the William James Book Award (1992, for The Science of Words), and the Award for Lifetime Contributions to Psychology (2003), and named a prize after him, as did the Cognitive Neuroscience Society. Miller was also honored by the Association for Psychological Science and the American Speech and Hearing Association. In 2000, he won the John P. McGovern Award in the Behavioral Sciences from the American Association for the Advancement of Science, and in 1991, the National Medal of Science, the country's highest scientific honor.

  7. George Gamow: Scientific Amateur and Polymath

    Harper, Eamon

    George Gamow (1904-1968) was among the first of the many brilliant scientists who forsook Europe for the United States in the early 1930s. Although most were fleeing the fascist imperium of Hitler and Mussolini, Gamow was one of a few who managed to escape the burgeoning despotism of Stalin in the Soviet Union. His early application of quantum mechanics to the atomic nucleus and his subsequent insight into the role played by the physics of the atom and its nucleus in stars, galaxies, and the universe identifies him as a scientist of unusual genius. Gamow displayed a boisterous, infectious - almost Rutherfordian - interest in all aspects of pure science. His interests were broad and his industry prodigious. His scientific output covered areas as diverse as nuclear physics, astrophysics, cosmology, biological genetics, and the fascinating question of the relationship of the large-scale structure and development of the universe to the properties of elementary particles and fields. He also was an immensely imaginative and prolific author of popular expositions on scientific subjects. One who is as well-known for his authorship of the Mr. Tompkins series of science popularizations as for his contributions to the development of the physical consequences of the big-bang theory of the expanding universe and the prediction of the cosmic background radiation must be unique in the scientific pantheon.

    Purpose: To report the design and imaging methodology of a photoacoustic scanner dedicated to imaging hemoglobin distribution throughout a human breast. Methods: The authors developed a dedicated breast photoacoustic mammography (PAM) system using a spherical detector aperture based on our previous photoacoustic tomography scanner. The system uses 512 detectors with rectilinear scanning. The scan shape is a spiral pattern whose radius varies from 24 to 96 mm, thereby allowing a field of view that accommodates a wide range of breast sizes. The authors measured the contrast-to-noise ratio (CNR) using a target comprised of 1-mm dots printed on clear plastic. Each dot absorption coefficient was approximately the same as a 1-mm thickness of whole blood at 756 nm, the output wavelength of the Alexandrite laser used by this imaging system. The target was immersed in varying depths of an 8% solution of stock Liposyn II-20%, which mimics the attenuation of breast tissue (1.1 cm−1). The spatial resolution was measured using a 6 μm-diameter carbon fiber embedded in agar. The breasts of four healthy female volunteers, spanning a range of breast size from a brassiere C cup to a DD cup, were imaged using a 96-mm spiral protocol. Results: The CNR target was clearly visualized to a depth of 53 mm. Spatial resolution, which was estimated from the full width at half-maximum of a profile across the PAM image of a carbon fiber, was 0.42 mm. In the four human volunteers, the vasculature was well visualized throughout the breast tissue, including to the chest wall. Conclusions: CNR, lateral field-of-view and penetration depth of our dedicated PAM scanning system is sufficient to image breasts as large as 1335 mL, which should accommodate up to 90% of the women in the United States.

    1987-01-01

    The concept of a series of dedicated robotics manipulators that would be resident in the subsystems of the Space Station is presented. These would be used to do Orbital Replacement Unit (ORU) exchanges, inspection of the components, and in certain cases subsystem assembly. By performing these well-definded tasks automatically, higher crew productivity would be achieved. In order to utilize the robots effectively, ORU's must be designed to allow remote release and quick disconnection of the electrical, fluid, and thermal connections. The robot must be of a modular design for ease of maintenance and must have an adaptive control capability to make-up for slight errors in programming.

    2015-06-01

    X-ray mammography of the compressed breast is well recognized as the "gold standard" for early detection of breast cancer, but its performance is not ideal. One limitation of screening mammography is tissue superposition, particularly for dense breasts. Since 2001, several research groups in the USA and in the European Union have developed computed tomography (CT) systems with digital detector technology dedicated to x-ray imaging of the uncompressed breast (breast CT or BCT) for breast cancer screening and diagnosis. This CT technology--tracing back to initial studies in the 1970s--allows some of the limitations of mammography to be overcome, keeping the levels of radiation dose to the radiosensitive breast glandular tissue similar to that of two-view mammography for the same breast size and composition. This paper presents an evaluation of the research efforts carried out in the invention, development, and improvement of BCT with dedicated scanners with state-of-the-art technology, including initial steps toward commercialization, after more than a decade of R&D in the laboratory and/or in the clinic. The intended focus here is on the technological/engineering aspects of BCT and on outlining advantages and limitations as reported in the related literature. Prospects for future research in this field are discussed. PMID:26127031

  14. Twisting and Writhing with George Ellery Hale

    NASA Astrophysics Data System (ADS)

    Canfield, Richard C.

    2013-06-01

    Early in his productive career in astronomy, George Ellery Hale developed innovative solar instrumentation that allowed him to make narrow-band images. Among the solar phenomena he discovered were sunspot vortices, which he attributed to storms akin to cyclones in our own atmosphere. Using the concept of magnetic helicity, physicists and mathematicians describe the topology of magnetic fields, including twisting and writhing. Our contemporary understanding of Hale's vortices as a consequence of large-scale twist in sunspot magnetic fields hinges on a key property of helicity: conservation. I will describe the critical role that this property plays, when applied to twist and writhe, in a fundamental aspect of global solar magnetism: the hemispheric and solar cycle dependences of active region electric currents with respect to magnetic fields. With the advent of unbroken sequences of high-resolution magnetic images, such as those presently available from the Helioseismic and Magnetic Imager on Solar Dynamics Observatory, the flux of magnetic helicity through the photosphere can be observed quantitatively. As magnetic flux tubes buoy up through the convection zone, buffeted and shredded by turbulence, they break up into fragments by repeated random bifurcation. We track these rising flux fragments in the photosphere, and calculate the flux of energy and magnetic helicity there. Using a quantitative model of coronal currents, we also track connections between these fragments to calculate the energy and magnetic helicity stored at topological interfaces that are in some ways analogous to the storage of stress at faults in the Earth's crust. Comparison of these values to solar flares and interplanetary coronal mass ejections implies that this is the primary storage mechanism for energy and magnetic helicity released in those phenomena, and suggests a useful tool for quantitative prediction of geomagnetic storms.

    George W. Wetherill, 1997 National Medal of Science recipient, died from heart failure on 19 July 2006, at his Washington, DC home. Wetherill can be rightfully called the father of modern theories of the formation of the Earth. Prior to the first Protostars and Planets meeting in Tucson in 1978, planet formation theories tended to be eccentric concoctions created by distinguished senior scientists who had earned the right to dream a little bit about how our Solar System had formed. Wetherill was in the vanguard of the effort to place planet formation theory on a solid basis. Born in Philadelphia on 12 August 1925, Wetherill served in the U.S. Navy during World War II, teaching radar at the Naval Research Laboratory in the District. He graduated from the University of Chicago in 1953 after receiving a succession of degrees: Ph.B., S.B., S.M., and Ph.D. Wetherill joined the staff of the Carnegie Institution's Department of Terrestrial Magnetism (DTM), located in northwest Washington, DC, in 1953. He and his colleagues at DTM and Carnegie's Geophysical Laboratory proceeded to revolutionize the field of geochemical dating of rocks by applying the physics he had learned at Chicago. Wetherill conceived of the concordia diagram, which uses the decay of radioactive uranium into lead to provide accurate dates for when the rocks crystallized. Wetherill's concordia diagram was a concept that found immediate and lasting acceptance, and stands as a singular achievement in the earth sciences. It opened up the field of geological dating for events that happened billions of years ago on the Earth and on other rocky bodies. Wetherill's great early success in geochemistry led to his being appointed as a professor of geophysics and geology at UCLA in 1960. At UCLA, Wetherill began his second major undertaking, working on the orbital evolution of asteroids and of other small bodies in the Solar System. He was the first to show that debris kicked out from meteorite impacts on Mars

    A method and system for job backfill scheduling dedicated heterogeneous nodes in a multi-node computing environment. Heterogeneous nodes are grouped into homogeneous node sub-pools. For each sub-pool, a free node schedule (FNS) is created so that the number of to chart the free nodes over time. For each prioritized job, using the FNS of sub-pools having nodes useable by a particular job, to determine the earliest time range (ETR) capable of running the job. Once determined for a particular job, scheduling the job to run in that ETR. If the ETR determined for a lower priority job (LPJ) has a start time earlier than a higher priority job (HPJ), then the LPJ is scheduled in that ETR if it would not disturb the anticipated start times of any HPJ previously scheduled for a future time. Thus, efficient utilization and throughput of such computing environments may be increased by utilizing resources otherwise remaining idle.

    1979-01-01

    An advanced technology, fully dedicated nuclear-electrolytic hydrogen production facility is presented. This plant will produce hydrogen and oxygen only and no electrical power will be generated for off-plant use. The conceptual design was based on hydrogen production to fill a pipeline at 1000 psi and a 3000 MW nuclear base, and the base-line facility nuclear-to-shaftpower and shaftpower-to-electricity subsystems, the water treatment subsystem, electricity-to-hydrogen subsystem, hydrogen compression, efficiency, and hydrogen production cost are discussed. The final conceptual design integrates a 3000 MWth high-temperature gas-cooled reactor operating at 980 C helium reactor-out temperature, direct dc electricity generation via acyclic generators, and high-current density, high-pressure electrolyzers based on the solid polymer electrolyte approach. All subsystems are close-coupled and optimally interfaced and pipeline hydrogen is produced at 1000 psi. Hydrogen costs were about half of the conventional nuclear electrolysis process.

  19. Dedicated storage rings for nuclear physics

    SciTech Connect

    Jackson, H.E.

    1984-01-01

    The use of internal targets in circulating beams of electron storage and stretcher rings has been widely discussed recently as a method of achieving high luminosity under conditions of low background, and good energy resolution, with minimal demands for beam from an injecting accelerator. In the two critical areas of the technology, ring design and target development, research is very active, and the prospects for major advances are very bright. Reasonable extrapolations of the current state of the art suggest for many problems in nuclear physics, particularly polarization physics of the nucleon and few body nuclei, internal target measurement may be the optimum experimental technique. This paper, discusses the comparative merit of internal target rings and external beam experiments, reviews briefly current research efforts in the critical areas of the technology, and establishes one goal for the discussions at the workshop. It appears that storage rings dedicated to internal target physics may offer a powerful option for future advances in nuclear physics.

    2014-05-01

    A series of oceanographic surveys on Georges Bank document variability of populations of the toxic dinoflagellate Alexandrium fundyense on time scales ranging from synoptic to seasonal to interannual. Blooms of A. fundyense on Georges Bank can reach concentrations on the order of 10(4) cells l(-1), and are generally bank-wide in extent. Georges Bank populations of A. fundyense appear to be quasi-independent of those in the adjacent coastal Gulf of Maine, insofar as they occupy a hydrographic niche that is colder and saltier than their coastal counterparts. In contrast to coastal populations that rely on abundant resting cysts for bloom initiation, very few cysts are present in the sediments on Georges Bank. Bloom dynamics must therefore be largely controlled by the balance between growth and mortality processes, which are at present largely unknown for this population. Based on correlations between cell abundance and nutrient distributions, ammonium appears to be an important source of nitrogen for A. fundyense blooms on Georges Bank. PMID:24976691

  19. Deep-water hydrocarbon potential of Georges Bank Trough

    SciTech Connect

    Levie, D.S. Jr.

    1985-02-01

    Characterization of the petroleum potential for Georges Bank Trough has been based primarily on limited organic geochemical data that indicate the area of recent drilling activity behind the paleoshelf edge to be poor in organic carbon and C/sub 15/ + extract values, with predominantly terrestrial kerogen types. Maturation data also suggest an inadequate thermal history for hydrocarbon generation in the area. It is possible that the effects of heat flow from the New England Seamount Chain may contribute to hydrocarbon generation in the Georges Bank Trough - a relationship that may also exist between the Newfoundland Seamount Chain and the Hibernia area of the Grand Banks. Also, comparisons can be drawn between the Atlantic Fracture Zone bordering the Georges Bank Trough and the Romanche-St. Paul Fracture Zone off the Ivory Coast. In the latter region, restricted anoxic environments with sediments rich in marine kerogen types have been identified, as have both structural and stratigraphic trapping mechanisms. Within this rhombochasm configuration, reservoir lithologies of sandstone and carbonate turbidites, fractured deep-water chalks, and reefal limestones should occur. The relationships of seamount to fracture zone, as applied to the rhombochasm model for the Georges Bank Trough, should enhance the hydrocarbon potential of the lower Mesozoic sediments seaward of the paleoshelf edge and thus classify this area as a future major hydrocarbon province.

    The DOE recently issued a policy statement that it would use dedicated trains for most waste shipments to Yucca Mountain. Prior uncertainty about use of dedicated trains for Yucca Mountain rail shipments prevented an assessment of the likely impacts. This paper examines the controversy over the use of dedicated trains and evaluates the national impacts of shipping waste to Yucca Mountain using dedicated trains on the Union Pacific's preferred rail system. The national impacts of the routing are reported as route miles through three land use types: Rural, Urban and Census Places. (authors)

    A few days before the beginning of the 7th European Conference on Applied Superconductivity we learned that Professor Jan Evetts, a pioneer of superconductor research, a brilliant scientist, a wonderful person and a great personal friend, had passed away. We therefore decided to dedicate the 7th European Conference on Applied Superconductivity to the memory of Jan Evetts. The following citation is based on material provided by his former supervisor (D Dew-Hughes) and his closest co-workers in Cambridge. Professor Jan Edgar Evetts (1939-2005) Professor Jan Edgar Evetts (1939-2005) Jan Evetts passed away after losing his second battle with cancer on 24th August 2005. He made an outstanding series of contributions to the science of superconductivity and to the understanding of superconducting materials and was an indefatigable champion of the development of applications of superconductivity. The loss to the superconductivity community is incalculable, as attested by the many communications received from colleagues throughout the world. Jan was born on 31 March 1939, and attended the Dragon School in Oxford, and later Haileybury. He was awarded an exhibition to read Natural Sciences at Pembroke College, Cambridge. He entered the college in 1958 and took his BA degree in 1961. He then undertook a Certificate of Postgraduate Study in Physics under the supervision of Professor Neville Mott. He was the first student to undertake this newly-instituted course; the title of his thesis was `The Resistance of Transition Metals'. In 1962 he joined David Dew-Hughes' superconducting materials research group, along with Archie Campbell and Anant Narlikar. In fact it was Jan's enthusiasm for the proposed course of research that helped convince David that he should follow Professor Alan Cottrell's suggestion to apply metallurgical methodology to the study of the factors that controlled critical current density in the type II superconductors that were then under development for

Some 15 or 20 years ago, when a restoration was crudely attempted, the old oaken flooring, which was invariably placed at the bottom of canal locks, was roughly torn up and destroyed. The trunks and stumps of gigantic trees still remain from this restorative effort, and their girth indicates again the antiquity of this evidence of George Washington's work as an engineer. The stones are of the red Seneca type and were evidently ferried from the Maryland side above the dam and then brought by sled or rollers to this location.

    DiGeorge syndrome results from defect in the development of the third and fourth pharyngeal pouches, and is characterized by conotruncal heart defects, aplasia or hypoplasia of thymus and parathyroid glands resulting in immune deficiency and hypocalcemia. Other associated abnormalities include renal, thyroid and diaphragmatic defects, oral clefting, etc. Etiologically, it is heterogeneous, with a microdeletion of 22q11 present in over 80% of cases. Our patient was born following a pregnancy complicated by insulin dependent gestational diabetes. There was truncus arteriosus type 2, absense of thymic shadow on CXR with severe deficiency of T cell function, and persistent hypocalcemia with low parathormone. Right kidney was absent. Dysplastic ribs including fused and bifid ribs were noted. Hypoplastic vertebrae and hemivertebrae were present through thoracic and lumbar regions. Chromosome analysis was normal, and metaphase FISH analysis with probe N25 representing locus D22S75 did not show any deletion of 22q11.2. The skeletal findings similar to these have not been previously reported in association with DiGeorge syndrome to our knowledge. Vertebral and rib abnormalities are known to occur with pregestational maternal diabetes. Maternal diabetes has also been suggested to be a possible etiology in a very small proportion of DiGeorge syndrome cases. It is possible that these findings occured together on account of gestational maternal diabetes in our case.

    Willson, Lee Anne; Struck, Curtis

    2011-12-01

    Our colleague and collaborator George Hamilton Bowen, Jr., passed away November 1, 2009 in Ames, Iowa. George was born June 20, 1925 in Tulsa, Oklahoma to George and Dorothy (Huntington) Bowen. He married Marjorie Brown June 19, 1948 in Redondo Beach, California; they had five children, with eight grandchildren and five great-grandchildren at the time of his death. George H. Bowen's third or perhaps his fourth career was in astronomy. He was drafted into the navy in 1944, at the end of his first year as a student at Caltech, and ended his war-time service as an electronic technician on the aircraft carrier Shangri-La. He later said "In just nine months, starting from scratch (Ohm's law!), we learned an amazing amount - not by memorization, of course, but by study and real understanding of the basic function of the most advanced AC circuits then being used for instrumentation, measurements, communications, control systems, and much more." He gained a confidence that he could quickly and accurately diagnose and solve technical problems that stood him well in future work. One accomplishment he took particular pride in was figuring out how the radar control used cams and gears to solve the trigonometry for accurate pointing. He also described how the captain was alarmed when weather conditions changed so that refraction no longer showed them distant, small boats around the curvature of Earth. After the war, George Bowen returned to undergraduate and eventually graduate study at Caltech, where he was recruited to the biophysics research group headed by future Nobel Laureate Max Delbrück. George often described his joy in working with these first-rate scientists and finding himself accepted as a part of the effort. He finished his BS with honors in 1949 and his PhD in 1953 with a thesis on "Kinetic Studies on the Mechanism of Photoreactivation of Bacteriophase T2 Inactivated by Ultraviolet Light" involving work with E Coli. This work was supported by grants from the U

    The George B. Pegram Award for Excellence in the Teaching of Physics was developed by a representative group of SESAPS members over a period of eight years with outstanding contributions as follows: Jesse Beams, APS President, with the advice of Mark Zemansky, AAPT, chose George B. Pegram as the honoree, in view of his excellent teaching career at Columbia University, his graduation from Trinity College--now Duke University, his long period of service as Treasurer of APS, and his active support of the special training program at ORAU; Earle Plyler with the assistance of Edward Burke, Jr., prepared the selection criteria for the recipients of the award; Walter Gordy coordinated the APS approval and initiated the financing of the program; Howard Carr raised the first funds and prepared the initial certificates; William G. Pollard joined the committee and completed the early funding, while preparing the formal certificate and medal; Dr. Vernet Eaton, AAPT President, stimulated the program when he urged the nomination of SESAPS members for the Oersted Award. After his lectures at the 1955 Gainesville meeting, Wendell Holladay instructed the committee to report its recommendations at the next SESAPS meeting. In 1969 SESAPS approved the George B. Pegram Award.

The outermost node of the computer network is a dedicated EPROM-based controller. The controller handles the details of driving the attached nuclear instrumentation, providing a standard interface to the remainder of the network. This paper addresses the design and the implementation of the dedicated instrumentation controller.

  12. Obituary: George Hamilton Bowen Jr. (1925-2009)

    Our colleague and collaborator George Hamilton Bowen, Jr., passed away November 1, 2009 in Ames, Iowa. George was born June 20, 1925 in Tulsa, Oklahoma to George and Dorothy (Huntington) Bowen. He married Marjorie Brown June 19, 1948 in Redondo Beach, California; they had five children, with eight grandchildren and five great-grandchildren at the time of his death. George H. Bowen's third or perhaps his fourth career was in astronomy. He was drafted into the navy in 1944, at the end of his first year as a student at Caltech, and ended his war-time service as an electronic technician on the aircraft carrier Shangri-La. He later said "In just nine months, starting from scratch (Ohm's law!), we learned an amazing amount - not by memorization, of course, but by study and real understanding of the basic function of the most advanced AC circuits then being used for instrumentation, measurements, communications, control systems, and much more." He gained a confidence that he could quickly and accurately diagnose and solve technical problems that stood him well in future work. One accomplishment he took particular pride in was figuring out how the radar control used cams and gears to solve the trigonometry for accurate pointing. He also described how the captain was alarmed when weather conditions changed so that refraction no longer showed them distant, small boats around the curvature of Earth. After the war, George Bowen returned to undergraduate and eventually graduate study at Caltech, where he was recruited to the biophysics research group headed by future Nobel Laureate Max Delbrück. George often described his joy in working with these first-rate scientists and finding himself accepted as a part of the effort. He finished his BS with honors in 1949 and his PhD in 1953 with a thesis on "Kinetic Studies on the Mechanism of Photoreactivation of Bacteriophase T2 Inactivated by Ultraviolet Light" involving work with E Coli. This work was supported by grants from the U

  13. Sir George Shuckburgh Evelyn (1751-1804): precision in thermometry.

    PubMed

    Pearn, John

    The universal clinical procedure of recording a patient's temperature depends upon the accuracy of thermometers. This in turn depends upon the accuracy of two fixed datum points (the freezing and boiling points of water) and subsequently on the fine calibration of the etched scale between them. Anders Celsius (1701-44) defined the boiling point of water as the upper fixed point of the thermometric scale, originally designated as 0°C but inverted by Carl Linnaeus (1707-78) to read 100°C. In 1724 Gabriel Fahrenheit (1686-1736) had observed that the upper fixed point, that of boiling water, varied with changes in atmospheric pressure. An English scientist, Sir George Shuckburgh (after 1794 known as Sir George Shuckburgh Evelyn), addressed this problem and over the period 1774-79 he defined the relationship of the temperature of boiling water to barometric pressure. This latter variable changed both with the ambient meteorological conditions of the moment and the height above sea level at which the calibrations were made. Clinical thermometry depends on an accuracy of 0.1°C in both the baseline and the tracking of a patient's temperature but Shuckburgh's experiments showed that the upper fixed point of reference, that of boiling water, could change by up to 10°C. He demonstrated that these variables must be measured and controlled in the manufacture and calibration of thermometers. Sir George Shuckburgh Evelyn published his results in the Philosophical Transactions of The Royal Society (1777-79) and made possible the accuracy of thermometry on which patient care depends.

    Wright, H.

    When first published in 1966, Helen Wright's Explorer of the universe brought public recognition to astronomer George Ellery Hale's (1868 - 1938) pre-eminent role in 20th-century science. With this timely republication (featuring a new introduction by Alan Sandage and a complete index), Hale's accomplishments and his fascinating, mercurial personality are brought to life for a new generation. Drawing on extensive research and interviews with Hale's colleagues, associates, and friends, as well as many of the astronomers he inspired, this work is an authoriative and affectionate biography and a revealing look back at the birth and development of modern astrophysics.

  15. George Kelly: cognitive psychologist, humanistic psychologist, or something else entirely?

    PubMed

    Benjafield, John G

    2008-11-01

    George Kelly was regarded by some of his contemporaries as a cognitive psychologist and by others as a humanistic psychologist. Kelly himself resisted being rubricized. He did, however, name several people who had been influential in his life and work, one of whom was J.F. Herbart. A comparison of Herbart and Kelly reveals several similarities. Both shared a belief that psychology was fundamentally a mathematical discipline. Both eliminated distinctions usually taken for granted in psychology, such as emotion versus cognition. Reconstructing Kelly's relation to Herbart allows one to see more clearly why Kelly was such a unique figure in 20th century psychology.

  16. Tuberculosis, bronchiectasis, and infertility: what ailed George Orwell?

    Ross, John J

    2005-12-01

    In the last and most productive years of his life, George Orwell struggled with pulmonary tuberculosis, dying at the dawn of the era of chemotherapy. His case history illustrates clinical aspects of tuberculosis with contemporary relevance: the role of poverty in its spread, the limited efficacy of monotherapy, the potential toxicity of treatment, and the prominence of cachexia as a terminal symptom. Orwell's ordeals with collapse therapy may have influenced the portrayal of the tortures of Winston Smith in the novel 1984. I discuss unifying diagnoses for Orwell's respiratory problems and apparent infertility, including tuberculous epididymitis, Young syndrome, immotile cilia syndrome, and cystic fibrosis.

    Professor H Winter. It was with great sadness that we learnt of the death of colleague and friend Professor Hannspeter Winter in Vienna on the 8 November 2006. In memory of him and the contribution he made both to our conference and to the field of the physics of highly charged ions we dedicate these proceedings. Hannspeter was one of our distinguished invited speakers at HCI2006 and gave a talk on the status of the ITER programme. His invited paper on the subject is included in these proceedings. Hannspeter will be particularly remembered for his pioneering work on ion-surface interactions that, together with his colleagues at the Vienna University of Technology (TUW), has stimulated a worldwide experimental and theoretical interest in this field. He was appointed Director of the Institut fuer Allgemeine Physik at TUW in 1987 and using both his scientific and management skills has made it one of the leading university physics laboratories in the world. His research publications, of which there are 270, have inspired many others to work in the field of atomic and plasma physics. He was also a great European playing a major role in the EURATOM fusion programme, the European Physical Society and the International Union of Pure and Applied Physics and was an evaluator and advisory board member for many national and international institutions. Hannspeter was also an interesting and friendly social companion with interests in current affairs, music and fine wines and will be greatly missed both on a scientific and social level. Our condolences go to his wife Renate, son Dorian and his relatives. R W McCullough Co-chair HCI2006

    Osterbrock, D. E.

    1998-05-01

    Caltech and the 200-inch Hale telescope on Palomar are two of George Ellery Hale's many creations in Southern California. He brought the California Institute of Technology into existence in 1920; Palomar Observatory was built for it. However, even before Hale had "secured" the funds for the 200-inch, astrophysical research had been underway on the Caltech campus in Pasadena, and it intensified after the Rockefeller grant came through. Interactions between the campus, Palomar Mountain, and Mount Wilson Obervatory (one of Hale's earlier creations) played important roles in determining the course of Caltech astrophysics. Changing funding patterns (from private philanthropy to drought, then "defense" weapons-development programs, and then governmental agencies designed to support scientific research) will be briefly described. The 18-inch Schmidt, built at the Caltech (200-inch Telescope) Shop, went into operation in 1936, the first research telescope on Palomar. The 200-inch, essentially completed, was dedicated in 1948 and went into operation for regularly scheduled research observations near the end of 1949. Its coude spectrograph was completed and put into regular use in stages from 1950 to 1952, Among the most important leaders of Caltech astrophysics up to 1948 and the years immediately after it when the 200-inch went into full operation were Robert A. Millikan, Max Mason, and Lee A. DuBridge. Some of the astrophysicists who worked at Caltech and Palomar were Albert Einstein, Richard C. Tolman, Fritz Zwicky, Ira S. Bowen, John A. Anderson, Sinclair Smith, John Strong, William A. Fowler and, just at the end of this period, Jesse L. Greenstein. Some of the key staff personnel were Russell W. Porter, Don O. Hendrix (on loan), and Byron Hill.

  19. Invertebrate predators of zooplankton on Georges Bank, 1977 1987

    NASA Astrophysics Data System (ADS)

    Sullivan, Barbara K.; Meise, Carol J.

    Chaetognaths, primarily Sagitta elegans, were the most abundant and widespread invertebrate predator on Georges Bank during 1977-1987 MARMAP surveys. They were present in 79% of samples collected, and their average abundance was nearly an order of magnitude greater than that of any other predator taxon. hydrozoan and scyphozoan medusae, euphausiid shrimp, and gammarid and hyperiid amphipods were also abundant. Diversity and abundance of predators was highest in the central, well-mixed region of the bank. In this region numbers of chaetognaths and cnidaria increased following increased abundances of Calanus finmarchicus. However, on a larger scale the density of C. finmarchicus populations was inversely correlated with number of predators because this herbivore was most abundant in deeper waters surrounding Georges Bank where predators were least numerous. Chaetognaths and cnidaria were more abundant in 1978-1979 than in other years, and there was a statistically significant decline in the abundance of chaetognaths over the 10 year period. Abundance of both these groups was inversely correlated with temperature. Average numbers of chaetognaths in summer were low following a warm winter. Abundance of cnidaria in summer decreased with increasing summer temperatures.

    2005-01-01

    Fish were collected at six sites at George Washington Carver National Monument by seining and electrofishing during a base-flow period on July 17-18, 2003. Approximately 700 fish were collected and identified at the six sampling sites. Those individuals represented 17 species (and 1 hybrid) and 13 genera. The number of species collected at the five stream sites ranged from 9 to 12; a hybrid sunfish and 4 species were collected from a pond. Fish collected at stream sites were typical of small headwater streams and no species collected in this study are federally-listed threatened or endangered species. The three most common species were the southern redbelly dace, central stoneroller, and green sunfish. Some differences existed between the assemblages (groups of species) collected in 2003 and in the previous inventories. Four of the 17 fish species collected in this inventory previously had not been collected at the monument. However, 11 species collected in one or more of the previous inventories were not collected in this effort. There is no indication that a change in environmental conditions is responsible for the absence of these species; more likely reasons are seasonal variability, extirpation, low population density, and misidentification. Four species collected at George Washington Carver National Monument may be of special interest to National Park Service managers and others. The cardinal shiner and stippled darter are endemic to the Ozark Plateaus. The Arkansas darter is considered a species of conservation concern by the State of Missouri. The grass carp is an introduced species.

  1. Sand-wave movement on Little Georges Bank

    1983-01-01

    A 1-x-1.5-km area on Little Georges Bank (centered at 41?08?N., 68?04?W.) was mapped three times during a ten-month period by sidescan sonar and echo-sounding techniques to assess the morphology and mobility of sand waves on Georges Bank. Sand-wave amplitudes in the survey area ranged from 1-11 m although most were 5-7 m. Wavelengths were not constant as the crests were sinuous and in places, even bifurcated. The sand waves are asymmetrical with their steepest sides facing northwest; however, gradients of their steep sides mostly are 4?-10? which is well below the angle of repose for sand in water. Sand waves tended to have greater relief and a sharper asymmetry during the survey in September than during those in June or April. During the survey period the sand waves moved but the direction and rate of motion was variable. Even along an individual sand wave some parts moved as much as 60 m between surveys while other parts apparently remained stationary. The sand waves were asymmetrical, but movement was not consistently in the direction that the steep sides faced. Along the same sand wave, parts moved to the northwest while other parts moved to the southeast. Despite the complex pattern of sand motion, the mean displacement of the sand waves was below the resolution of the survey technique; to resolve it, a longer survey is needed.

    This biographical sketch on Georg Hermann von Meyer highlights the interactions in the 1860s that von Meyer, a famous anatomist, had with Karl Culmann, a famous structural engineer and mathematician. The published papers from this interaction caught the attention of Julius Wolff and stimulated his development of the trajectorial hypothesis of bone adaptation--now called "Wolff's Law." The corresponding translations are provided: (1) von Meyer's 1867 paper that highlights the regularity of arched trabecular patterns in various human bones, and his discussions with Culmann about their possible mechanical relevance; and (2) Wolff's 1869 paper that first mentions the correspondence of stress trajectories in a solid, crane-like structure to the arched trabecular patterns in the proximal human femur. This biographical sketch on Georg Hermann von Meyer corresponds to the historic texts, The Classic: The Architecture of the Trabecular bone (by von Meyer), and The Classic: On the Significance of the Architecture of the Spongy Substance for the Question of Bone Growth. A preliminary publication (by Wolff) available at DOIs 10.1007/s11999-011-2041-5 , 10.1007/s11999-011-2042-4 . PMID:21901583

  3. Eocene paleosols of King George Island, Maritime Antarctica

    2016-04-01

    Red layers between lava flows on King George Island, Maritime Antarctica, were formed during the Eocene, which was one of the warmest periods on Earth in the Cenozoic. Our hypothesis is that these red layers are paleosols formed in periods of little or no volcanic activity. Therefore, our main objective was to identify the main pedogenic properties and features to distinguish these from diagenetic features formed after the lava emplacement. Additionally, we compared our results with volcanic soils formed under different climates to find the best present analogue. The macromorphological features indicate a pedogenic origin, because of the occurrence of well-defined horizons based on colour and structure. Micromorphological analyses showed that most important pedogenic features are the presence of biological channels, plant residues, anisotropic b-fabric, neoformed and illuvial clay and distinct soil microstructure. Although the paleosols are not strongly weathered, the geochemical data also support the pedogenic origin despite of diagenetic features as the partial induration of the profiles and zeolites filling nearly all voids in the horizons in contact with the overlying lava flow, indicating circulation of hydrothermal fluids. The macromorphological and micromorphological features of these paleosols are similar to the soils formed under seasonal climates. Thus, these paleosol features do not correspond to the other proxies (e.g. sediment, plant fossils), which indicate a wet, non-seasonal climate, as in Valdivian Forest, Chile, during the Eocene in King George Island

    The focus of this humanbecoming hermeneutic study of graduate nursing students' reflections is on being dedicated as portrayed in the documentary film, The American Nurse. Nursing students were invited to a public screening of the film, with the director, Carolyn Jones, and asked to write a brief reflective essay on "what is the meaning of being dedicated depicted in the film The American Nurse." The perspective is to be the humanbecoming school of thought. The participants were 20 nurses either in a graduate or doctoral nursing program at the time of this study. The emergent meanings of the study are offered to enhance knowledge and understanding of being dedicated. The use of documentary film to expand graduate nursing students' awareness of global issues is also considered. PMID:26660779

    2013-01-01

    Background Scheduling emergency cases among elective surgeries often results in prolonged waits for emergency surgery and delays or cancellation of elective cases. We evaluated the benefits of a dedicated operating room (OR) for emergency procedures available to all surgical services at a large children’s hospital. Methods We compared a 6-month period (January 2009 to June 2009) preimplementation with a 6-month period (January 2010 to June 2010) postimplementation of a dedicated OR. We evaluated OR use, wait times, percentage of cases done within and outside of access targets, off-hours surgery, cancellations, overruns and length of stay. Results Preimplementation, 1069 of the 5500 surgeries performed were emergency cases. Postimplementation, 1084 of the 5358 surgeries performed were emergency cases. Overall use of the dedicated OR was 53% (standard deviation 25%) postimplementation. Excluding outliers, the average wait time for priority 3 emergency patients decreased from 11 hours 8 minutes to 10 hours 5 minutes (p = 0.004). An increased proportion of priority 3 patients, from 52% to 58%, received surgery within 12 hours (p = 0.020). There was a 9% decrease in the proportion of priority 3 cases completed during the evening and night (p < 0.001). The elective surgical schedule benefited from the dedicated OR, with a significant decrease in cancellations (1.5% v. 0.7%, p < 0.001) and an accumulated decrease of 5211 minutes in overrun minutes in elective rooms. The average hospital stay after emergency surgery decreased from 16.0 days to 14.7 days (p = 0.12) following implementation of the dedicated OR. Conclusion A dedicated OR for emergency cases improved quality of care by decreasing cancellations and overruns in elective rooms and increasing the proportion of priority 3 patients who accessed care within the targeted time.

    The advent of cloud computing centres such as Amazon's EC2 and Google's Computing Engine has elicited comparisons with dedicated computing clusters. Discussions on appropriate usage of cloud resources (both academic and commercial) and costs have ensued. This presentation discusses a detailed analysis of the costs of operating and maintaining the RACF (RHIC and ATLAS Computing Facility) compute cluster at Brookhaven National Lab and compares them with the cost of cloud computing resources under various usage scenarios. An extrapolation of likely future cost effectiveness of dedicated computing resources is also presented.

    DiGeorge syndrome is a rare congenital disease that affects the baby's immune system. Its symptoms vary greatly between individuals but commonly include a history of recurrent infection, heart defects, and characteristic facial features. Few cases of DiGeorge syndrome have been reported in adults. The article describes rare (three cases of DiGeorge syndrome) in adults (18, 32 and 34 years old patients) in Georgia (Caucasus). In clinical practice DiGeorge syndrome may proceed under the course of gastroenterologic, endocrine, nervous and surgical symptoms. 3 cases of DiGeorge syndrome are reported in the article. The authors describe DiGeroge syndrome as a multidisciplinary disorder; it is masqueraded by acute surgical diseases; with sharp immunodeficiency and endocrine, cardiologic and neurologic semiotics.

    Pomeroy, J.S.

    1989-01-01

    Prince Georges County was identified during a statewide investigation of landslide susceptibility (MF-2048) as the county with the most serious slope-stability problems. This map uses a ranking system ranging from 1 (nil to very low susceptibility) to 4 (moderate to severe susceptibility). Geologic factors and precipitation are major elements in the initiation of landslides in the county. The Potomac Group and the Marlboro Clay are the most slideprone units. This map should enable users to make a rapid, generalized evaluation of the potential for mass movement. Planners, engineers, soil scientists, geologist, university faculty, and elected officials should find it useful in the assessment of slope hazards for county-wide analyses.

    For George Herbert Mead, thinking amounts to holding an "inner conversation of gestures ". Such a conception does not seem especially original at first glance. What makes it truly original is the "social-behavioral" approach of which it is a part, and, particularly, two ideas. The first is that the conversation in question is a conversation of gestures or attitudes, and the second, that thought and reflexive intelligence arise from the internalization of an external process supported by the social mechanism of communication: that of conduct organization. It imports then to understand what distinguishes such ideas from those of the founder of behavioral psychology, John B. Watson, for whom thinking amounts to nothing other than subvocal speech.

    George Huntington described some families with choreiform movements in 1872 in the United States of America and since then many such families have been described in other parts of the world and works on the genetics of the disease have brought new vistas in the understanding of the disease. In 1958, Americo Negrette, a young Venezuelan physician observed similar subjects in the vicinity of Lake Maracaibo which was presented by his co-worker, Ramon Avilla Giron at New York in 1972 when United States of America had been commemorating the centenary year of Huntington's disease. Nancy Wexler, a psychoanalyst, whose mother had been suffering from the disease attended the meeting and organized a research team to Venezuela and they systematically studied more than 18,000 individuals in order to work out a common pedigree. They identified the genetic locus of the disease in the short arm of chromosome 4 and observed that it was a trinucleotide repeat disorder. PMID:27011624

  7. George Hartley Bryan, Ludwig Boltzmann, and the Stability of Flight

    A century ago, George Hartley Bryan (1864-1928) published his classic book, Stability in Aviation. I draw together some strands from events that awakened his interest in the nascent science of aviation, in particular the stability of flight. Prominent among those who influenced him was Ludwig Boltzmann (1844-1906), who held Bryan in high esteem for his contributions to thermodynamics and kinetic theory. I argue that the seeds of Bryan's interest in aviation were sown at the British Association meeting at Oxford in the summer of 1894, at which Boltzmann was guest of honor. A joint discussion between Section A (Mathematical and Physical Science) and Section G (Mechanical Science) was devoted to the problems of flight, during the course of which Boltzmann revealed a hitherto unsuspected enthusiasm for flying.

    The story of the noted composer George Gershwin's psychoanalysis and death resulting from an undiagnosed brain tumor 70 years ago are known today only in a garbled, incomplete form through biography and legend rather than history among psychoanalysts, neurologists, and neurosurgeons. This article examines his psychoanalysis with Gregory Zilboorg and the events and course of his final illness to the extent possible with the historical material now available. It provides an account of the behavior of his psychoanalyst in a variety of contexts as well as the actions of the other physicians attending him. We cannot know, but can only infer, what went on in his psychoanalytic sessions or his medical examinations; about this the reader will have to draw his or her own conclusions.

    2009-01-01

    After five years with no public schools in their community, residents and neighborhood organizations of the Near Westside of Indianapolis advocated for the opening of George Washington Community High School (GWCHS). As a neighborhood in close proximity to the campus of Indiana University-Purdue University Indianapolis, the Near Westside and campus worked together to address this issue and improve the educational success of youth. In fall 2000, GWCHS opened as a community school and now thrives as a national model, due in part to its network of community relationships. This account analyzes the development of the school by focusing on the relationships among the university, the high school, community organizations, and the residents of the Near Westside and highlights the unique partnership between the campus and school by defining the relational qualities and describing the network created to make sustainable changes with the high school.

  12. SUBSIDENCE, CRUSTAL STRUCTURE, AND THERMAL EVOLUTION OF GEORGES BANK BASIN.

    1987-01-01

    A geographical study of Georges Bank basin defines a deep crustal structure that is interpreted in terms of the basin's tectonic and thermal history. Gravity models along three basin cross sections delineate two zones of crustal thinning at the basement hinge zone and oceanic crustal margins. These two zones bound rift-stage crust (about 25 km thick) which underlies the central portion of the basin. Subsidence analysis of the basin, using data from multichannel seismic reflection lines and two COST wells, suggests a rifting and (uniform) extensional origin. Two-dimensional finite difference modeling of the basin defines a crustal structure that concurs with the gravity and subsidence studies. The resulting isotherms show no major changes in the thermal structure since the Late Jurassic. In some areas of the basin, temperature sufficient for oil generation are determined from maturation studies of Jurassic sediments. Hydrocarbon generation is questionable, however, because of the probable lack of proper and sufficient kerogen in the Jurassic deposits.

  13. Mobile fishing gear reduces benthic megafaunal production on Georges Bank

    2003-01-01

    This study addresses the effect of mobile fishing gear disturbance on benthic megafaunal production on the gravel pavement of northern Georges Bank. From 1994 to 2000, we sampled benthic megafauna with a 1 m Naturalists' dredge at shallow (47 to 62 m) and deep (80 to 90 m) sites. The cessation of fishing in large areas of Georges Bank in January 1995 allowed us to monitor changes in production at a previously disturbed site. Production at a shallow disturbed site varied little over the sampling period (32 to 57 kcal m-2 yr-1) and was markedly lower than production at the nearby recovering site, where production increased from 17 kcal m-2yr -1 in 1994 before the closure to 215 kcal m-2 yr -1 in 2000. Atlantic sea scallops Placopecten magellanicus and green sea urchins Strongylocentrotus droebachiensis dominated production at the recovering site. The community production:biomass ratio decreased over time at the recovering site as the sea scallop population matured. At the deep sites, production remained significantly higher at undisturbed sites (174 to 256 kcal m-2 yr-1) than at disturbed sites (30 to 52 kcal m -2 yr-1). The soft-bodied tube-building polychaete Thelepus cincinnatus dominated production at the undisturbed site, while hard-shelled bivalve molluscs Astarte spp. and P. magellanicus were prevalent at the disturbed site. Mobile fishing gear disturbance has a conspicuous effect on benthic megafaunal production in this hard-bottom habitat. Cessation of mobile fishing has resulted in a marked increase in benthic megafaunal production. These findings should help fishery managers to gauge the costs and benefits of management tools such as area closures and low-impact fishing gears.

  14. Profiling optimization for big data transfer over dedicated channels

    SciTech Connect

    Yun, D.; Wu, Qishi; Rao, Nageswara S; Kettimuthu, R.; Jung, E. S.

    2016-01-01

    The transfer of big data is increasingly supported by dedicated channels in high-performance networks, where transport protocols play an important role in maximizing applicationlevel throughput and link utilization. The performance of transport protocols largely depend on their control parameter settings, but it is prohibitively time consuming to conduct an exhaustive search in a large parameter space to find the best set of parameter values. We propose FastProf, a stochastic approximation-based transport profiler, to quickly determine the optimal operational zone of a given data transfer protocol/method over dedicated channels. We implement and test the proposed method using both emulations based on real-life performance measurements and experiments over physical connections with short (2 ms) and long (380 ms) delays. Both the emulation and experimental results show that FastProf significantly reduces the profiling overhead while achieving a comparable level of end-to-end throughput performance with the exhaustive search-based approach.

    2007-09-01

    In order to sell grain lots in European countries, seed industries need a government certification. This certification requests purity testing, seed counting in order to quantify specified seed species and other impurities in lots, and germination testing. These analyses are carried out within the framework of international trade according to the methods of the International Seed Testing Association. Presently these different analyses are still achieved manually by skilled operators. Previous works have already shown that seeds can be characterized by around 110 visual features (morphology, colour, texture), and thus have presented several identification algorithms. Until now, most of the works in this domain are computer based. The approach presented in this article is based on the design of dedicated electronic vision machine aimed to identify and sort seeds. This machine is composed of a FPGA (Field Programmable Gate Array), a DSP (Digital Signal Processor) and a PC bearing the GUI (Human Machine Interface) of the system. Its operation relies on the stroboscopic image acquisition of a seed falling in front of a camera. A first machine was designed according to this approach, in order to simulate all the vision chain (image acquisition, feature extraction, identification) under the Matlab environment. In order to perform this task into dedicated hardware, all these algorithms were developed without the use of the Matlab toolbox. The objective of this article is to present a design methodology for a special purpose identification algorithm based on distance between groups into dedicated hardware machine for seed counting.

    High-density demersal layers of krill have been detected in the submarine canyons off Georges Bank by means of a high-frequency, dual-beam bioacoustical technique. Krill densities in these demersal layers were observed to be two to three orders of magnitude greater than the highest densities observed in water-column scattering layers. Such abundances may help explain the unusually high squid and demersal fish production estimates attributed to the Georges Bank ecosystem. PMID:17734865

    High-density demersal layers of krill have been detected in the submarine canyons off Georges Bank by means of a high-frequency, dual-beam bioacoustical technique. Krill densities in these demersal layers were observed to be two to three orders of magnitude greater than the highest densities observed in water-column scattering layers. Such abundances may help explain the unusually high squid and demersal fish production estimates attributed to the Georges Bank ecosystem.

    The life and works of Georg Groddeck are reviewed and placed in historical context as a physician and a pioneer of psychoanalysis, psychosomatic medicine, and an epistolary style of writing. His Das Es concept stimulated Freud to construct his tripartite model of the mind. Groddeck, however, used Das Es to facilitate receptivity to unconscious communication with his patients. His "maternal turn" transformed his treatment approach from an authoritarian position to a dialectical process. Groddeck was a generative influence on the development of Frieda Fromm-Reichmann, Erich Fromm, and Karen Horney. He was also the mid-wife of the late-life burst of creativity of his friend and patient Sándor Ferenczi. Together, Groddeck and Ferenczi provided the impetus for a paradigm shift in psychoanalysis that emphasized the maternal transference, child-like creativity, and a dialogue of the unconscious that foreshadowed contemporary interest in intersubjectivity and field theory. They were progenitors of the relational turn and tradition in psychoanalysis. Growing interest in interpsychic communication and field theory is bringing about a convergence of theorizing among pluralistic psychoanalytic schools that date back to 1923 when Freud appropriated Groddeck's Das Es and radically altered its meaning and use.

    The St. George Basin was the site of mafic volcanism from about 6 Ma to 1 ka. The nature of latest Quaternary volcanism is of interest because the Basin is recognized as a low temperature (< 90C) geothermal resource area and it is part of the transition zone between the Basin and Range Province and the Colorado Plateau. The authors have studied the geochemistry, mineralogy, and aerial distribution of two of the youngest eruptions centers: (1) Veyo Volcano; and (2) the Diamond Valley scoria cones (DVSC). Veyo Volcano erupted basaltic andesite, beginning with an explosive stage marked by a 0.5 m basal Plinian layer. Later eruptions alternated between quiescent and Strombolian-styles. Phenocrysts include clear plagioclase, sieve-texture plagioclase, olivine and rare augite. The DVSC and associated Santa Clara lava flow are tholeiitic basalt, consisting of olivine phenocrysts, and rare plagioclase phenocrysts. Based on preliminary geochemical data, Diamond Valley rocks exhibit lower incompatible element ratios compared to mafic rocks on the Markagunt Plateau and transition zone rocks. In contrast, Veyo Volcano rocks are similar to transition zone mafic rocks with regard to incompatible element abundances.

  16. Identifying the patient in George W Lambert's Chesham Street

    2013-01-01

    This paper takes as its focus one of the Edwardian period's most dramatic and little-understood paintings of a medical examination: George Washington Lambert's Chesham Street (1910). The painting shows an upper-class male patient lifting his shirt to reveal a muscular torso for examination by the doctor in the scene and the viewers outside it. The subject of a medical examination, I argue, legitimised the scrutiny of exposed male flesh and offered an opportunity for sensual pleasure between men. By way of a comparison with other portraits of the artist from around the same period, I interpret Chesham Street as a patient self-portrait, which reveals the artist's dual personalities of bohemian artist and Australian boxer: two personae that did not combine seamlessly, as revealed by the composite nature of the patient in Chesham Street. From a discussion of the artist as patient, I move to an analysis of other self-portraits by Lambert in which the artist is shown flexing his muscles, especially in the context of his passion for boxing. I consider how these portraits serve as complex inscriptions of illness and health and how this relates to the experience of living and working as an Australian expatriate artist in London in the early twentieth century.

  17. Establishing the Canon: George Ripley and his alchemical sources.

    PubMed

    Rampling, Jennifer M

    2008-11-01

    George Ripley, Canon of Bridlington (ca. 1415 to ca. 1490) was one of England's most famous alchemists, whose alchemical opera attracted study and commentary throughout the sixteenth and seventeenth centuries, and were printed and translated both in England and abroad. Yet Ripley's frequently baffling texts have proved resistant to scholarly interpretation. This paper attempts to unravel some of Ripley's alchemical theories and practice, firstly by identifying his major sources, and secondly by gauging his response to these texts. For instance, although Ripley's interest in the corpus of alchemical texts pseudonymously attributed to Ramon Lull is well documented, it transpires that his best known work, the Compound of Alchemy, or Twelve Gates, is actually based not on a Lullian work, but on a Latin treatise that Ripley attributed to the little-known alchemist, Guido de Montanor. Further clues to Ripley's alchemical thought can be obtained by considering his handling of a potential conflict between his two authorities, Lull and Guido. The resulting insights into Ripley's alchemy provide an instrument for assessing which of Ripley's pseudoepigraphic works can be truly called "canonical". PMID:19244710

  18. Narrative and epistemology: Georges Canguilhem's concept of scientific ideology.

    PubMed

    Chimisso, Cristina

    2015-12-01

    In the late 1960s, Georges Canguilhem introduced the concept of 'scientific ideology'. This concept had not played any role in his previous work, so why introduce it at all? This is the central question of my paper. Although it may seem a rather modest question, its answer in fact uncovers hidden tensions in the tradition of historical epistemology, in particular between its normative and descriptive aspects. The term ideology suggests the influence of Althusser's and Foucault's philosophies. However, I show the differences between Canguilhem's concept of scientific ideology and Althusser's and Foucault's respective concepts of ideology. I argue that Canguilhem was in fact attempting to solve long-standing problems in the tradition of historical epistemology, rather than following the lead of his younger colleagues. I argue that Canguilhem's 'refurbishment without rejection' of Bachelard's epistemology, which the concept of scientific ideology was aimed to implement, was necessary to justify the historical narratives that Canguilhem had constructed in his own work as a historian of concepts. A strict acceptance of Bachelard's epistemology would have made it impossible to justify them. Canguilhem's concept of scientific ideology therefore served as a theoretical justification of his practice as a historian. I maintain that the concept of scientific ideology was needed to reconcile Bachelard's normative epistemology with Canguilhem's view of the history of science and its aims, which differed from Bachelard's more than it is generally acknowledged.

  19. Phrenology, heredity and progress in George Combe's Constitution of Man.

    PubMed

    Jenkins, Bill

    2015-09-01

    The Constitution of Man by George Combe (1828) was probably the most influential phrenological work of the nineteenth century. It not only offered an exposition of the phrenological theory of the mind, but also presented Combe's vision of universal human progress through the inheritance of acquired mental attributes. In the decades before the publication of Darwin's Origin of Species, the Constitution was probably the single most important vehicle for the dissemination of naturalistic progressivism in the English-speaking world. Although there is a significant literature on the social and cultural context of phrenology, the role of heredity in Combe's thought has been less thoroughly explored, although both John van Wyhe and Victor L. Hilts have linked Combe's views on heredity with the transformist theories of Jean-Baptiste Lamarck. In this paper I examine the origin, nature and significance of his ideas and argue that Combe's hereditarianism was not directly related to Lamarckian transformism but formed part of a wider discourse on heredity in the early nineteenth century.

  20. Comparison of Filters Dedicated to Speckle Suppression in SAR Images

    This paper presents the results of research on the effectiveness of different filtering methods dedicated to speckle suppression in SAR images. The tests were performed on RadarSat-2 images and on an artificial image treated with simulated speckle noise. The research analysed the performance of particular filters related to the effectiveness of speckle suppression and to the ability to preserve image details and edges. Speckle is a phenomenon inherent to radar images - a deterministic noise connected with land cover type, but also causing significant changes in digital numbers of pixels. As a result, it may affect interpretation, classification and other processes concerning radar images. Speckle, resembling "salt and pepper" noise, has the form of a set of relatively small groups of pixels of values markedly different from values of other pixels representing the same type of land cover. Suppression of this noise may also cause suppression of small image details, therefore the ability to preserve the important parts of an image, was analysed as well. In the present study, selected filters were tested, and methods dedicated particularly to speckle noise suppression: Frost, Gamma-MAP, Lee, Lee-Sigma, Local Region, general filtering methods which might be effective in this respect: Mean, Median, in addition to morphological filters (alternate sequential filters with multiple structuring element and by reconstruction). The analysis presented in this paper compared the effectiveness of different filtering methods. It proved that some of the dedicated radar filters are efficient tools for speckle suppression, but also demonstrated a significant efficiency of the morphological approach, especially its ability to preserve image details.

    Detection of p-nitrophenol, a product of several enzymatic reactions, is useful and important in many fields of modern bioanalytics. Here, we have developed and applied a complete photometer dedicated for such measurements that is extremely economic and easily customized for specific experimental setups. The instrument consists only of paired emitter-detector diodes (PEDDs) coupled with an extremely simple and low-cost signal transduction system. The experimental data confirmed that this photometric system adapted for cuvette as well as flow measurements can be applied for fast and reproducible determination of alkaline phosphatase (ALP) activity.

    Preliminary results suggest that Positron Emission Mammography (PEM) can offer a noninvasive method for the diagnosis of breast cancer. Metabolic images from PEM contain unique information not available from conventional morphologic imaging techniques and aid in expeditiously establishing the diagnosis of cancer. A dedicated machine seems to offer better perspectives in terms of position resolution and sensitivity. This paper describes the concept of Clear-PEM, the system presently developed by the Crystal Clear Collaboration at CERN for an evaluation of this approach. This device is based on new crystals introduced by the Crystal Clear as well as on modern data acquisition techniques developed for the large experiments in high energy physics experiments.

    Defect clusters such as linear or clustered porosity are in some cases even more important than single flaws. This paper presents two methods of defect clustering and algorithm for calculation of distances between flaws in digital radiographic image. Dedicated lookup table based filter is used for calculation of distances between objects in the specified range. For defect clustering two functions were developed. First one is based on MMD (Minimum Mean Distance) algorithm. Second one uses hierarchical procedures for clustering defects of various types, shapes and size.

    A dedicated Genetic Algorithm (GA) has been developed to localize the trajectory of ferromagnetic moving objects within a bounded perimeter. Localization of moving ferromagnetic objects is an important tool because it can be employed in situations when the object is obscured. This work is innovative for two main reasons: first, the GA has been tuned to provide an accurate and fast solution to the inverse magnetic field equations problem. Second, the algorithm has been successfully tested using real-life experimental data. Very accurate trajectory localization estimations were obtained over a wide range of scenarios. PMID:26393598

    Dedicated breast computed tomography (bCT) is currently being studied as a potential screening method for breast cancer. The X-ray exposure is set low to achieve an average glandular dose comparable to that of mammography, yielding projection data that contains high levels of noise. Iterative image reconstruction (IIR) algorithms may be well-suited for the system since they potentially reduce the effects of noise in the reconstructed images. However, IIR outcomes can be difficult to control since the algorithm parameters do not directly correspond to the image properties. Also, IIR algorithms are computationally demanding and have optimal parameter settings that depend on the size and shape of the breast and positioning of the patient. In this work, we design an efficient IIR algorithm with meaningful parameter specifications and that can be used on a large, diverse sample of bCT cases. The flexibility and efficiency of this method comes from having the final image produced by a linear combination of two separately reconstructed images - one containing gray level information and the other with enhanced high frequency components. Both of the images result from few iterations of separate IIR algorithms. The proposed algorithm depends on two parameters both of which have a well-defined impact on image quality. The algorithm is applied to numerous bCT cases from a dedicated bCT prototype system developed at University of California, Davis.

    1994-01-01

    The Spacecraft Control and Operations System 2 (SCOSII) is the new generation of Mission Control Systems (MCS) to be used at ESOC. The system is generic because it offers a collection of standard functions configured through a database upon which a dedicated MCS is established for a given mission. An integral component of SCOSII is the support of a dedicated Operations Language (OL). The spacecraft operation engineers edit, test, validate, and install OL scripts as part of the configuration of the system with, e.g., expressions for computing derived parameters and procedures for performing flight operations, all without involvement of software support engineers. A layered approach has been adopted for the implementation centered around the explicit representation of a data model. The data model is object-oriented defining the structure of the objects in terms of attributes (data) and services (functions) which can be accessed by the OL. SCOSII supports the creation of a mission model. System elements as, e.g., a gyro are explicit, as are the attributes which described them and the services they provide. The data model driven approach makes it possible to take immediate advantage of this higher-level of abstraction, without requiring expansion of the language. This article describes the background and context leading to the OL, concepts, language facilities, implementation, status and conclusions found so far.

    Gravel habitats on continental shelves around the world support productive fisheries but are also vulnerable to disturbance from bottom fishing. We conducted a 2-year in situ experiment to measure the rate of colonization of a gravel habitat on northern Georges Bank in an area closed to fishing (Closed Area II) since December 1994. Three large (0.25 m 2) sediment trays containing defaunated pebble gravel were deployed at a study site (47 m water depth) in July 1997 and recovered in June 1999. The undersides of the tray lids positioned 56 cm above the trays served as settlement panels over the same time period. We observed rapid colonization of the gravel substrate (56 species) and the settlement panels (35 species), indicating that colonization of gravel in this region is not limited by the supply of colonists. The species composition of the taxa found in the trays was broadly similar to that we collected over a 10-year period (1994-2004) in dredge samples from gravel sediments at the same site. The increase in abundance of animals in the gravel colonization trays was rapid and reached a level in 2 years that took 4.5 years to achieve in the surrounding gravel sediments once fishing had stopped, based on data from dredge sampling at this site. The increase in biomass of animals found in the sediment trays paralleled the trend of biomass increase observed in dredge samples over the same period (1997-1999) but was lower in value. These data suggest that after rapid initial increase in abundance of organisms, succession proceeded by increasing individual body size. A comparison of settlement panel and tray faunas revealed that the mean biomass of structure-forming epifauna (sponges, bryozoans, anemones, hydroids, colonial tube worms) on the panels was 8 times that found on the trays. Structure-forming taxa constituted 29% of the mean biomass of the panel fauna but only 5.5% of the tray fauna. By contrast, the mean biomass of scavengers (crabs, echinoderms, nudibranchs

    It has been said of Silas Weir Mitchell (1829-1914) that as a young man he was first among the physiologists of his day, in middle age first among physicians, and as an older man, one of the most noted novelists of his country. Mitchell's novels were written in his later life as a means to avoid boredom during lengthy summer vacations that were the norm for that time among the affluent members of Philadelphia society. These novels were criticized by some because of poor plots, which in some instances failed to move along, or for text that offered a stereotyped depiction of genteel society and the effects that war or personal disaster had on the characters' behavior The criticism came despite the fact that all critics agreed that Mitchell's portrayals of psychopathology in his fictional characters was unique and accurate. However, in his 30s, Mitchell had written and by chance had published a fictional short story that not only transcended such criticisms but became immensely popular. "The Strange Case of George Dedlow" portrays a union officer who was not a physician but who had some medical background and who sustained a series of war wounds leading to severe nerve pain, the author's first description of causalgia, multiple amputations, and the psychological as well as physical symptoms of phantom limb syndrome. The protagonist tells of his torments in the first person in a very engaging fashion. Thus, long before he began writing his, at that time, acclaimed novels in the 1880s, Mitchell wrote a piece of fiction that combines accurate and very important medical observations with fiction of great historical interest. The following rendering of this now classic short story includes selected quotes and some interpretation and is perhaps appropriate for this year, 2 years after the centenary year of his death in 1914.

    Involved in what is still considered, along with the two world wars of the 20th century, as one of the major conflicts in Europe, George James Guthrie (1785-1856) was the most famous English army surgeon of the Napoleonic wars. After treating the injured throughout the Peninsular Campaign (1808-1814), in 1815 and then in 1842 he published two major books dealing with cranial and brain injuries, among other topics. In these books, we can find, for example, an early description of the plantar reflex further described by Joseph Babinsky, accurate descriptions of the clinical signs of intracranial hypertension, and details of the physiopathology of subdural and epidural haematomas. Skull fractures are also discussed intensively, along with the indications for trepanation, a much-debated issue at the turn of the 19th century. The dura was often the limit of the surgical field for Guthrie. Nevertheless, he tried to rationalize the use of trepanation and favoured its use in two main cases: in cases of depressed skull bones, jammed bone fragments or debris irritating the dura or the brain and in cases of life-threatening cerebral compression caused by supposed blood clots. In their works, Guthrie and his contemporaries did not address neurosurgery in the modern sense of the word, but rather 'cranial surgery' in most cases. Guthrie, who saw so many patients with brain injuries and amputations, failed to understand that cerebral functions could be localized to the cortex and neglected to describe the phantom limb phenomenon, as did most of his contemporaries.

    1992-05-01

    Spacelab Life Sciences 1 was the first space laboratory dedicated to life science research. It was launched into orbit in early June 1991 aboard the space shuttle Columbia. The data from this flight have greatly expanded our knowledge of the effects of microgravity on human physiology as data were collected in-flight, not just pre and post. Principal goals of the mission were the measurement of rapid and semichronic (8 days) changes in the cardiovascular and cardiopulmonary systems during the flight and then to measure the rate of readaptation following return to Earth. Results from the four teams involved in that research will be presented in this panel. In addition to the cardiovascular-cardiopulmonary research, extensive metabolic studies encompassed fluid, electrolyte and energy balance, renal function, hematology and musculoskeletal changes. Finally, the crew participated in several neurovestibular studies. Overall, the mission was an outstanding success and has provided much new information on the lability of human responses to the space environment.

    Both educational institutions and health care agencies have a propensity to look to the past for solutions to their present and projected problems, such as the nursing shortage. One problem that continually surfaces and has become one of two primary limitations on expanding nursing school enrollments is finding and sustaining quality clinical experiences in acute care settings. The demand for these clinical sites continues to grow and the consequent need for effective clinical partnerships grows with it. The Dedicated Education Unit is a creative strategy for addressing the confluence of highly sophisticated marketing efforts promoting the profession of nursing as a whole, the high demand job market for nurses, and the increase in nursing school enrollments at both undergraduate and graduate levels.

  9. Neural-network dedicated processor for solving competitive assignment problems

    NASA Technical Reports Server (NTRS)

    Eberhardt, Silvio P. (Inventor)

    1993-01-01

    A neural-network processor for solving first-order competitive assignment problems consists of a matrix of N x M processing units, each of which corresponds to the pairing of a first number of elements of (R sub i) with a second number of elements (C sub j), wherein limits of the first number are programmed in row control superneurons, and limits of the second number are programmed in column superneurons as MIN and MAX values. The cost (weight) W sub ij of the pairings is programmed separately into each PU. For each row and column of PU's, a dedicated constraint superneuron insures that the number of active neurons within the associated row or column fall within a specified range. Annealing is provided by gradually increasing the PU gain for each row and column or increasing positive feedback to each PU, the latter being effective to increase hysteresis of each PU or by combining both of these techniques.

    Dedicated breast CT has great potential for improving the detection and diagnosis of breast cancer. In this study, statistical iterative reconstruction with a penalized likelihood objective function and a Huber prior are investigated for use with breast CT. This prior has two free parameters, the penalty weight and the edgepreservation threshold, that need to be evaluated to determine those values that give optimal performance. Computer simulations with breast-like phantoms were used to study these parameters using various figuresof- merit that relate to performance in detecting microcalcifications. Results suggested that a narrow range of Huber prior parameters give optimal performance. Furthermore, iterative reconstruction provided improved performance measures as compared to conventional filtered back-projection.

    The purpose of this review is to provide illustrative examples of diseases of the foot and ankle when imaged with a low-field MR imaging system. A retrospective review of 268 foot and ankle examinations, performed in our institution within the past 3 years with a 0.2-T (Artoscan Esaote, Genoa, Italy) dedicated extremity MR system was done. Additionally, illustrative comparison with conventional radiography and high-field MR imaging is presented in patients in whom these examinations were also performed. Although motion artifact limited the value of a few studies, in the majority of examinations low-field MR imaging provided diagnostic image quality for the full spectrum of disorders affecting the foot and ankle and seemed to be a feasible alternative to high-field MR imaging in establishing an accurate diagnosis.

  12. Development of new Hopkinson's device dedicated to rib's bone characterisation

    This study presents an original approach for the design of adapted Hopkinson device dedicated to the characterisation of human ribs' cortical bone. The quasi-static study carried out on flat samples coming from this anatomical part highlighted the importance of the critical effect of sample shape and location on the accuracy of identify mechanical behaviour. The access to higher rates of strains, Hopkinson bars technique are classically required whatever compression or tension loadings. Classical designs of measurement bars are not suitable for this purpose due to the complexity of specimen's geometry (thickness variation). In this context, a new design of SHTB is studied here on the basis on a Finite Element approach of the set measurement bars/biological coupon. Finite Element simulations have been conducted using Abaqus explicit code by varying the design configuration. The comparison on input and output elastic waves suggests a set of small diameter bars in polyamide 66 for a better signal measurement.

    An important measure of an innovation is the ease of replication and achievement of the same positive outcomes. The dedicated education unit (DEU) clinical education model uses a collaborative academic-service partnership to develop an optimal learning environment for students. The University of Portland adapted this model from Flinders University, Australia, to increase the teaching capacity and quality of nursing education. This article identifies DEU implementation essentials and reports on the outcomes of two replication sites that received consultation support from the University of Portland. Program operation information, including education requirements for clinician instructors, types of patient care units, and clinical faculty-to-student ratios is presented. Case studies of the three programs suggest the DEU model is adaptable to a range of different clinical settings and continues to show promise as one strategy for addressing the nurse faculty shortage and strengthening academic-clinical collaborations while maintaining quality clinical education for students.

    Plans for the first Spacelab-4 mission dedicated entirely to the life sciences, are reviewed. The thrust of the scientific mission scheduled for late 1985 will be to study the acute effects of weightlessness on living systems, particularly humans. The payload of the Spacelab compartment will contain 24 experiments of which approximately half will involve humans. Among the major areas of interest are cardiovascular and pulmonary function, vestibular function, renal and endocrine physiology, hematology, nitrogen balance, immunological function, the gravitational biology of plants, inflight fertilization of frogs' eggs and the effects of zero gravity on monkeys and rats. In selecting the array of experiments an effort was made to combine investigations with complementary scientific objectives to develop animal models of human biological problems.

    Much discussion in the literature centres on how best to teach medical students the intricacies of gynaecological assessment and the subsequent formulation of a management plan. At Keele University skills are initially developed in a simulated setting and then transferred to the workplace where students continue to develop their skills. A dedicated undergraduate gynaecology teaching clinic has been developed and comprises of 2-3 students and a tutor. All 38 students rotating through the department between January and June 2013 were invited to complete an anonymous questionnaire to evaluate this clinic and 36 (95%) of them responded. Respondents felt significantly more comfortable taking a gynaecology history, ensuring privacy during examination and formulating a management plan post-clinic (all p < 0.001), with female students feeling significantly more comfortable than their male counterparts (p = 0.04). The use of this clinic shows great promise to help students learn an unfamiliar and challenging skill. PMID:26492580

    The identification of complete networks of protein-protein interactions (PPI) within a cell has contributed to major breakthroughs in understanding biological pathways, host-pathogen interactions and cancer development. As a consequence, PPI have emerged as a new class of promising therapeutic targets. However, they are still considered as a challenging class of targets for drug discovery programs. Recent successes have allowed the characterization of structural and physicochemical properties of protein-protein interfaces leading to a better understanding of how they can be disrupted with small molecule compounds. In addition, characterization of the profiles of PPI inhibitors has allowed the development of PPI-focused libraries. In this review, we present the current efforts at developing chemical libraries dedicated to these innovative targets.

    The use of solid targets irradiated in a vacuum target chamber by focussed high energy, high power laser beams to study the properties of matter at high densities, pressures and temperatures are well known. An undesirable side effect of these interactions is the generation of plumes of solid, liquid and gaseous matter which move away from the target and coat or physically damage surfaces within the target chamber. The largest aperture surfaces in these chambers are usually the large, high specification optical components used to produce the extreme conditions being studied [e.g. large aperture off axis parabolas, aspheric lenses, X ray optics and planar debris shields]. In order to study these plumes and the effects that they produce a set of dedicated experiments were performed to evaluate target by product coating distributions and particle velocities by a combined diagnostic instrument that utilised metal witness plates, polymer witness plates, fibre velocimetry and low density foam particle catchers.

    In-house developed cameras and other commercial detectors are typically tested with x-ray tubes and at synchrotron beamlines before being deployed and used for science experiments. In a prototyping phase, this is needed to understand and characterize the behavior of the detector. In a more advanced development phase, measurements with x-rays are required to characterize and calibrate the camera. Tests at synchrotron beamlines in actual experimental conditions are indeed a valuable source for detector developers. However, when all photons arrive at once, as for FELs, the response of the detector can be very different from that obtained with a synchrotron beam which behaves more like a CW (continuous) source. This behavior was already observed during users runs at LCLS and recently investigated during dedicated detector beamtime. The linearity of the response of the Cornell-SLAC Pixel Array Detector (CSPAD) was investigated. Results are presented and discussed.

    The dedication of the new Environmental Sciences Laboratory coincided with the 25th year of the establishment of the science of ecology at Oak Ridge National Laboratory. That quarter century witnessed the evolution of ecology from an obscure, backwater discipline of biology to a broadly used, everyday household word. The transition reflected broad and basic changes in our social and cultural view of the world. This was brought about as a result of the awareness developed in our society of the importance of the environment, coupled with efforts of ecologists and other environmental scientists who identified, clarified, and formulated the issues and challenges of environmental protection for both the lay public and the scientific community. In many respects, the activities in ecology at ORNL were a microcosm of the broader social scene; the particular problems of the environment associated with atomic energy needed to be defined in scientific terms and articulated in both the specific and general sense for a larger audience which was unfamiliar with the field and somewhat alien to its concepts and philosophy. The success of this effort is reflected in the existence of the new Environmental Sciences Laboratory. This dedication volume brings together the thoughts and reflections of many of these scientists whose efforts contributed in a unique and individualistic fashion not only to ORNL but also to the national identification of ecology and its importance to the achievement of our national goals. Their remarks and presentations are not only a pleasant and personally gratifying recapitulation of the past and of ORNL's contributions to ecology but also portend some of the challenges to ecology in the future.

  1. Enabling Dedicated, Affordable Space Access Through Aggressive Technology Maturation

    A recent explosion in nano-sat, small-sat, and university class payloads has been driven by low cost electronics and sensors, wide component availability, as well as low cost, miniature computational capability and open source code. Increasing numbers of these very small spacecraft are being launched as secondary payloads, dramatically decreasing costs, and allowing greater access to operations and experimentation using actual space flight systems. While manifesting as a secondary payload provides inexpensive rides to orbit, these arrangements also have certain limitations. Small, secondary payloads are typically included with very limited payload accommodations, supported on a non interference basis (to the prime payload), and are delivered to orbital conditions driven by the primary launch customer. Integration of propulsion systems or other hazardous capabilities will further complicate secondary launch arrangements, and accommodation requirements. The National Aeronautics and Space Administration's Marshall Space Flight Center has begun work on the development of small, low cost launch system concepts that could provide dedicated, affordable launch alternatives to small, risk tolerant university type payloads and spacecraft. These efforts include development of small propulsion systems and highly optimized structural efficiency, utilizing modern advanced manufacturing techniques. This paper outlines the plans and accomplishments of these efforts and investigates opportunities for truly revolutionary reductions in launch and operations costs. Both evolution of existing sounding rocket systems to orbital delivery, and the development of clean sheet, optimized small launch systems are addressed. A launch vehicle at the scale and price point which allows developers to take reasonable risks with new propulsion and avionics hardware solutions does not exist today. Establishing this service provides a ride through the proverbial "valley of death" that lies between

    Recent technology advancements have enabled the development of small cheap satellites that can perform useful functions in the space environment. Currently, the only low cost option for getting these payloads into orbit is through ride share programs - small satellites awaiting the launch of a larger satellite, and then riding along on the same launcher. As a result, these small satellite customers await primary payload launches and a backlog exists. An alternative option would be dedicated nano-launch systems built and operated to provide more flexible launch services, higher availability, and affordable prices. The potential customer base that would drive requirements or support a business case includes commercial, academia, civil government and defense. Further, NASA technology investments could enable these alternative game changing options. With this context, in 2013 the Game Changing Development (GCD) program funded a NASA team to investigate the feasibility of dedicated nano-satellite launch systems with a recurring cost of less than $2 million per launch for a 5 kg payload to low Earth orbit. The team products would include potential concepts, technologies and factors for enabling the ambitious cost goal, exploring the nature of the goal itself, and informing the GCD program technology investment decision making process. This paper provides an overview of the life cycle analysis effort that was conducted in 2013 by an inter-center NASA team. This effort included the development of reference nano-launch system concepts, developing analysis processes and models, establishing a basis for cost estimates (development, manufacturing and launch) suitable to the scale of the systems, and especially, understanding the relationship of potential game changing technologies to life cycle costs, as well as other factors, such as flights per year.

    The East Georges Bank Basin is located offshore Nova Scotia on the southeastern Canadian continental shelf. The basin covers 2.5 million ac and is one of the last undrilled basins in North America. The geological interpretation is almost entirely based on 16,000 km of seismic data over the basin. Pertinent well control is limited to 10 wells on the US portion of the Georges Bank (West Georges Bank Basin) and two wells on the Scotian shelf. Seismic-stratigraphic analysis of this data has led to a structural and stratigraphic model for the basin. The basin formed during the Triassic when the landmass of Pange began separating along rift zones. A prominent Paleozoic basement high, the Yarmouth Arch separated the East Georges Bank Basin from the West Georges Bank Basin and had a dominant influence on sedimentation until the Middle Jurassic. Early synrift sequences consist of lacustrine clastics and shales. Marine incursions began in the late Triassic resulting in massive salt deposits that reflect the restricted extent of the basin and the arid Triassic and Early Jurassic climate. Further continental separation during the Early Jurassic resulted in deposition of carbonates and evaporites followed by Middle Jurassic continental shelf carbonates and deltaic sands. During the Middle Jurassic, major growth faulting and halokinesis was initiated by progradation of the deltaic sands. Post Middle Jurassic continental spreading in combination with changing climatic conditions resulted in a steady decline of carbonate sedimentation and dominance of clastic deposition throughout the remaining history of the basin.

  5. Modern sedimentation patterns in Potter Cove, King George Island, Antarctica

    IMCOAST among a number of other initiatives investigates the modern and the late Holocene environmental development of south King George Island with a strong emphasis on Maxwell Bay and its tributary fjord Potter Cove (maximum water depth: about 200 m). In this part of the project we aim at reconstructing the modern sediment distribution in the inner part of Potter Cove using an acoustic ground discrimination system (RoxAnn) and more than136 ground-truth samples. Over the past 20 years the air temperatures in the immediate working area increased by more than 0.6 K (Schloss et al. 2012) which is less than in other parts of the West Antarctic Peninsula (WAP) but it is still in the range of the recovery of temperatures from the Little Ice Age maximum to the beginning of the 20th century. Potter Cove is a small fjord characterized by a series of moraine ridges produced by a tidewater glacier (Fourcade Glacier). Presumably, the farthest moraine is not much older than about 500 years (LIA maximum), hence the sediment cover is rather thin as evidenced by high resolution seismic data. Since a few years at least the better part of the tidewater glacier retreated onto the island's mainland. It is suggested that such a fundamental change in the fjord's physiography has also changed sedimentation patterns in the area. Potter Cove is characterized by silty-clayey sediments in the deeper inner parts of the cove. Sediments are coarser (fine to coarse sands and boulders) in the shallower areas; they also coarsen from the innermost basin to the mouth of the fjord. Textural structures follow the seabed morphology, i.e. small v-shaped passages through the moraine ridges. The glacier still produces large amounts of turbid melt waters that enter the cove at various places. We presume that very fine-grained sediments fall out from the meltwater plumes and are distributed by mid-depth or even bottom currents, thus suggesting an anti-estuarine circulation pattern. Older sediments that are

    Climatic change in Antarctica is strongest over the Antarctic Peninsula where in places the annual mean temperatures increased by 0.5 K per decade through the past 60 years. The impact of this warming trend is clearly visible in the form of retreating glaciers and melting ice sheets, loss of sea ice and strong meltwater discharge into the coastal zone. While it is generally accepted that the rapidity of the present climate change bears a significant anthropogenic aspect, it is not clear whether the effects caused by the warming trend are exceptional and unprecedented or whether the reaction of the environment is similar to that of earlier climate phases such as the Medieval Warm Period (MWP) about 1,000 years ago. One of the major goals of the joint international research project IMCOAST is to investigate the strength of the recent warming trend and its impact on the marine environment of the West Antarctic Peninsula (WAP). The study we present here reveals the Upper Holocene climatic history based on high-resolution sediment cores from Maxwell Bay (King George Island, WAP) and information on the actual processes triggered or altered by the recent warming trend based on sedimentologic and hydroacoustic investigations in Potter Cove, a tributary fjord to Maxwell Bay. Long sediment cores from Maxwell Bay reveal grain-size changes that can be linked to cold and warm phases such as the Little Ice Age (LIA) and the MWP. Generally, warm phases are finer grained than cold phases as a result of longer and stronger melting processes during the warm phases. It is suggested that meltwater plumes carry fine-grained sediment out of the surrounding fjords into Maxwell Bay where it settles in suitable areas to produce sediments that have a modal value around 16 μm. This mode is largely absent in sediments deposited during e.g. the LIA. However, post LIA sediments are depleted in the 16 μm-mode sediment suggesting slightly different conditions during the last century. One reason

    Georges Schaltenbrand was one of the most prodigious and internationally renowned neurologists in post war Germany. Trained by Max Nonne in Hamburg, he early gained international experience during stays in The Netherlands, the United States, and China. In 1935 quarrels with Nazi representatives forced him to go to Würzburg, where he built an own neurological service. This unit subsequently grew up to an internationally recognized center. Schaltenbrand scientifically contributed to the organization and diagnostics of the motor system, to the physiology and pathology of the cerebrospinal fluid system, and to multiple sclerosis. His textbook and atlas on stereotaxy, authored with his American friend Percival Bailey in 1959, remained a standard reference in stereotactic surgery until recent years. Only late after his death his unethical scientific activities during wartime came to common public knowledge. In an attempt to confirm his hypothesis of an infectious aetiology of multiple sclerosis, he had inoculated mentally handicapped and other severely ill patients with cerebrospinal fluid of apes putatively suffering from multiple sclerosis and also of patients with verified multiple sclerosis. He explicitly accepted the risk of causing some morbidity and even mortality in his study persons. He published his experiments in several articles and oral presentations since 1940, and, comprehensively, in a monograph 1943. Although commented as early as 1949, his dubious studies were widely ignored until a critical review appeared in an American journal in 1994. Since then, the studies are frequently cited as a typical example of Nazi medical science. However, with due regard to the historical background and the personality of Schaltenbrand his experiments should rather be brought into line with a worldwide practice at that time of using patients as study objects without asking for their consent. As a response to this practice several laws had been adopted, beginning in 1900

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived bare earth (BE) and first surface (FS) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Northeast Coastal and Barrier Network, Kingston, RI; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of the George Washington Birthplace National Monument in Virginia, acquired on March 26, 2008. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL) was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using the EAARL

    Panorama Plus (Natera), a single-nucleotide polymorphism- (SNP-) based approach that relies on the identification of maternal and fetal allele distributions, allows the detection of common aneuploidies and also incorporates a panel of 5 microdeletions including Di George syndrome. We report here the first case of Di George syndrome detected by NIPT in Italy; blood was drawn at 12 weeks' gestation. The patient had an amniocentesis to confirm the diagnosis by MLPA (multiplex ligation-dependent probe amplification) and an ultrasound aimed to detect the features associated with the syndrome. A right aortic arch and suspect of thymus atrophy were detected, but not other severe malformations typical of the disease. The patient terminated the pregnancy at 17 weeks. NIPT allowed an early screening of Di George syndrome. As the patient was at low risk, it is likely that an ultrasound would have missed the condition. PMID:26346617

    George Bligh Bank, situated at the north-eastern end of the Rockall Plateau, forms part of an extensive system of elevated submarine topography in the UK's Exclusive Economic Zone of the northeast Atlantic. Through the UK's Strategic Environmental Assessment programme, these seamounts and offshore banks have only recently been investigated in any detail, allowing the first photographic record of epibenthic megafaunal communities. The results presented here are based on photographic and video observations along seven transects on George Bligh Bank, covering a depth range from 425 to 1338 m. Diverse communities of sedentary suspension-feeding organisms were observed along five of the seven transects, with some evidence of localised hard coral frameworks. Community composition on George Bligh Bank is similar to those observed on other hard substrata in the deep northeast Atlantic.

    The goal of St. George (STrong Gradient Electromagnetic Online Recoil separator for capture Gamma ray Experiments) is to measure (α, γ) cross sections relevant to stellar helium burning. Recoil separators such as St. George are able to more closely approach the low astrophysical energies of interest because they collect reaction recoils rather than γ-rays, and thus are not limited by room background. In order to obtain an accurate cross section measurement, a recoil separator must be able to collect all recoils over their full range of expected energy and angular spread. The energy acceptance of St. George is currently being measured, and the angular acceptance will be measured soon. Here we present the results of COSY ion optics simulations and magnetic field analyses which were performed to help guide the commissioning measurements and diagnostic upgrades required to complete those measurements.

  12. New hypothesis helps explain elasmobranch "outburst" on Georges Bank in the 1980s.

    Regime shifts are a feature of many ecosystems. During the last 40 years, intensive commercial exploitation and environmental changes have driven substantial shifts in ecosystem structure and function in the northwest Atlantic. In the Georges Bank-southern New England region, commercially important species have declined, and the ecosystem shifted to one dominated by economically undesirable species such as skates and dogfish. Aggregated abundance indices indicate a large increase of small and medium-sized elasmobranchs in the early 1980s following the decline of many commercial species. It has been hypothesized that ecological interactions such as competition and predation within the Georges Bank region were responsible for and are maintaining the "elasmobranch outburst" at the heart of the observed ecosystem shift. We offer an alternative hypothesis invoking population connectivity among winter skate populations such that the observed abundance increase is a result of migratory dynamics, perhaps with the Scotian Shelf (i.e., it is an open population). Here we critically evaluate the survey data for winter skate, the species principally responsible for the increase in total skate abundance during the 1980s on Georges Bank, to assess support for both hypotheses. We show that time series from different surveys within the Georges Bank region exhibit low coherence, indicating that a widespread population increase was not consistently shown by all surveys. Further, we argue that observed length-frequency data for Georges Bank indicate biologically unrealistic population fluctuations if the population is closed. Neither finding supports the elasmobranch outburst hypothesis. In contrast, survey time series for Georges Bank and the Scotian Shelf are negatively correlated, in support of the population connectivity hypothesis. Further, we argue that understanding the mechanisms of ecosystem state changes and population connectivity are needed to make inferences about both

    Purpose: Dedicated breast CT has great potential for improving the detection and diagnosis of breast cancer. Statistical iterative reconstruction (SIR) in dedicated breast CT is a promising alternative to traditional filtered backprojection (FBP). One of the difficulties in using SIR is the presence of free parameters in the algorithm that control the appearance of the resulting image. These parameters require tuning in order to achieve high quality reconstructions. In this study, the authors investigated the penalized maximum likelihood (PML) method with two commonly used types of roughness penalty functions: hyperbolic potential and anisotropic total variation (TV) norm. Reconstructed images were compared with images obtained using standard FBP. Optimal parameters for PML with the hyperbolic prior are reported for the task of detecting microcalcifications embedded in breast tissue.Methods: Computer simulations were used to acquire projections in a half-cone beam geometry. The modeled setup describes a realistic breast CT benchtop system, with an x-ray spectra produced by a point source and an a-Si, CsI:Tl flat-panel detector. A voxelized anthropomorphic breast phantom with 280 μm microcalcification spheres embedded in it was used to model attenuation properties of the uncompressed woman's breast in a pendant position. The reconstruction of 3D images was performed using the separable paraboloidal surrogates algorithm with ordered subsets. Task performance was assessed with the ideal observer detectability index to determine optimal PML parameters.Results: The authors' findings suggest that there is a preferred range of values of the roughness penalty weight and the edge preservation threshold in the penalized objective function with the hyperbolic potential, which resulted in low noise images with high contrast microcalcifications preserved. In terms of numerical observer detectability index, the PML method with optimal parameters yielded substantially improved

    Purpose: To determine the mean and range of volumetric glandular fraction (VGF) of the breast in a diagnostic population using a high-resolution flat-panel cone-beam dedicated breast CT system. This information is important for Monte Carlo-based estimation of normalized glandular dose coefficients and for investigating the dependence of VGF on breast dimensions, race, and pathology. Methods: Image data from a clinical trial investigating the role of dedicated breast CT that enrolled 150 women were retrospectively analyzed to determine the VGF. The study was conducted in adherence to a protocol approved by the institutional human subjects review boards and written informed consent was obtained from all study participants. All participants in the study were assigned BI-RADS{sup Registered-Sign} 4 or 5 as per the American College of Radiology assessment categories after standard diagnostic work-up and underwent dedicated breast CT exam prior to biopsy. A Gaussian-kernel based fuzzy c-means algorithm was used to partition the breast CT images into adipose and fibroglandular tissue after segmenting the skin. Upon determination of the accuracy of the algorithm with a phantom, it was applied to 137 breast CT volumes from 136 women. VGF was determined for each breast and the mean and range were determined. Pathology results with classification as benign, malignant, and hyperplasia were available for 132 women, and were used to investigate if the distributions of VGF varied with pathology. Results: The algorithm was accurate to within {+-}1.9% in determining the volume of an irregular shaped phantom. The study mean ({+-} inter-breast SD) for the VGF was 0.172 {+-} 0.142 (range: 0.012-0.719). VGF was found to be negatively correlated with age, breast dimensions (chest-wall to nipple length, pectoralis to nipple length, and effective diameter at chest-wall), and total breast volume, and positively correlated with fibroglandular volume. Based on pathology, pairwise statistical

    The development of a framework of deformable image registration and segmentation for the purpose of temporal subtraction contrast-enhanced breast CT is described. An iterative histogram-based two-means clustering method was used for the segmentation. Dedicated breast CT images were segmented into background (air), adipose, fibroglandular and skin components. Fibroglandular tissue was classified as either normal or contrast-enhanced then divided into tiers for the purpose of categorizing degrees of contrast enhancement. A variant of the Demons deformable registration algorithm, intensity difference adaptive Demons (IDAD), was developed to correct for the large deformation forces that stemmed from contrast enhancement. In this application, the accuracy of the proposed method was evaluated in both mathematically-simulated and physically-acquired phantom images. Clinical usage and accuracy of the temporal subtraction framework was demonstrated using contrast-enhanced breast CT datasets from five patients. Registration performance was quantified using normalized cross correlation (NCC), symmetric uncertainty coefficient, normalized mutual information (NMI), mean square error (MSE) and target registration error (TRE). The proposed method outperformed conventional affine and other Demons variations in contrast enhanced breast CT image registration. In simulation studies, IDAD exhibited improvement in MSE (0-16%), NCC (0-6%), NMI (0-13%) and TRE (0-34%) compared to the conventional Demons approaches, depending on the size and intensity of the enhancing lesion. As lesion size and contrast enhancement levels increased, so did the improvement. The drop in the correlation between the pre- and post-contrast images for the largest enhancement levels in phantom studies is less than 1.2% (150 Hounsfield units). Registration error, measured by TRE, shows only submillimeter mismatches between the concordant anatomical target points in all patient studies. The algorithm was

    A dedicated small-angle X-ray scattering (SAXS) beamline using a new X-ray source generated by an In-Acromat superconducting wiggler (IASW6) insertion device is under construction at the National Synchrotron Radiation Research Center (NSRRC). The IASW6 with peak magnetic field of 3.1 T, magnet period of 6.1 cm, and total length of 96 cm, can provide a photon flux ˜ 1012 - 1013photons/s/0.1%bw in the energy range of 5 - 23 keV. Taking the central 0.2 mard horizontal radiation fan from the source with a beam divergence of 200 and 392 μrad in the vertical and horizontal directions, respectively, the dedicated SAXS beamline is oriented for nano to meso-structural research in soft matter, including liquid crystals, macromolecular solutions, polymers, as well as in nanoparticles, ceramic, and alloys. The SAXS beamline adopts the design of the double-monochromator used in the beamline SIYBLS at ALS, which integrates a Si(111) double crystal monochromator (DCM) and a Mo/B4C double multilayer monochromator (DMM) into one cradle for fast exchange between the two monochrmators. Equipped with a collimating mirror (CM) and a toroidal focusing mirror (FM) with 1:1 focusing ratio, this beamline provides two types of SAXS measurements: high-Q resolution and high flux, by using either the DCM or DMM. The SAXS beamline also provides energy scan with an energy resolution from 1 to 10 eV for anomalous SAXS (ASAXS) measurements. A specially coated reflecting mirror is also installed after FM to provide a suitable photon beam for grazing incident SAXS of liquid surfaces. Ray tracing simulation results show that at 8 keV and with DCM, a high quality photon beam of beam size (0.5 mm) and beam divergence (± 50 μrad) with a flux of ˜ 1011 photons/s can be obtained for high-Q resolution SAXS measurement. The photon flux can be increased by one order of magnitude when the DMM is used; however, the beam size and divergence are both slightly increased.

    Georges Bank is a shallow part of the Atlantic continental shelf southeast of New England (Emery and Uchupi, 1972, 1984). This bank, however, is merely the upper surface of several sedimentary basins overlying a block-faulted basement of igneous and metamorphic crystalline rock. Sedimentary rock forms a seaward-thickening cover that has accumulated in one main depocenter and several ancillary depressions, adjacent to shallow basement platforms of paleozoic and older crystalline rock. Georges Bank basin contains a thickness of sedimentary rock greater than 10 km, whereas the basement platforms that flank the basin are areas of thin sediment accumulation (less than 5 km).

    2009-12-01

    Cognition research in Geoscience is the focus of a small group of faculty from the College of Science and the College of Education and Human Development at George Mason University. We approached this research when we were involved in an Institution-wide effort to assess critical thinking, one of the competencies mandated for evaluation by the State Council of Higher Education of Virginia. Our group started spontaneously and informally from personal interests and enthusiasm for what and how our students are learning about Geology and in general about science. We want to understand what our students bring to the course, their attitude towards science, their knowledge of the scientific enterprise and preconceived ideas—and what our students take away from the course, beyond the course content. We believe that, with the support of cognitive science, we can improve the learning experience and therefore enhance the learning outcomes for science and non-science majors alike. Our Institution offers introductory Physical and Historical Geology classes populated primarily by non-science-major undergraduates. Geology lectures range in size from 90 to over 220 students per session per semester, with laboratory sessions averaging 27 students per session. With this large student population, it is necessary to use research tools that give us valuable information about student cognition, while being efficient in terms of time use and logistics. Some examples of our work include critical readings on Geoscience topics, surveys on students’ understanding of science as a way of knowing, exercises with built-in self-efficacy assessments, and concept mapping. The common denominator among these tools is that they are calibrated to address one or more of the higher levels in the revised Bloom’s Taxonomy of the Cognitive Domain, which form a complex assessment of student learning processes. These tools, once refined, can provide us with a better view of how our students learn in

    1993-04-15

    The use of motor current signature analysis (CSA) has been established as a useful method for periodic monitoring of electrically driven equipment. CSA is, moreover, especially well suited as the basis for a dedicated continuous monitoring system in an industrial setting. This paper presents just such an application that has been developed and installed in the US government uranium enrichment plant at Portsmouth, Ohio. The system, which is designed to detect specific axial-flow compressor problems in 1700-hp gaseous diffusion compressors, is described in detail along with an explanation of detected fault conditions and the required signal manipulations. Amplitude demodulation and subsequent digital processing of motor signals sensed from area control room ammeter loops are used to accomplish the desired monitoring task. Using modified off-the-shelf multiplexing equipment, a 386-type personal computer, and special digital signal processing hardware, the system is presently configured to monitor ten compressors but is expandable to monitor more than 100. Within its first few days of operation in September 1992, the system detected a compressor problem that, when corrected, resulted in a cost avoidance of about $150,000, which more than paid for the hardware and software development costs. Finally, plans to expand system coverage in the coming year are also discussed.

    The Comoros Basin, a region of eddies that propagate into the Mozambique Channel and subsequently the Agulhas Current, has not been well studied. This paper presents the findings from the first dedicated research cruise in the basin. ADCP data collected during the cruise show that the circulation in the Comoros Basin is dominated by the strong westward flowing North East Madagascar Current, which bifurcates twice: once upon encountering the Davie Ridge and again upon reaching the East African coast. One of the branches flows southward along the African coastline and appears to continue into the Mozambique Channel while the other branch turns northward to become the East African Coastal Current. The ADCP data also show evidence of a cyclonic eddy along the northwest coast of Madagascar. Water mass analysis indicates that all the major Indian Ocean water masses are present in the Comoros Basin. Surprisingly, North Atlantic Deep Water, a water mass previously assumed to only occur south of ˜16°S in the Mozambique Channel, was found to be present in the basin at depths below 2000 m. Antarctic Intermediate Water is found to enter the basin via two routes; from the west within the North East Madagascar Current and from the south within the northward flowing Mozambique Undercurrent.

    Spacelab is a large versatile laboratory carried in the bay of the Shuttle Orbiter. The first Spacelab mission dedicated entirely to Life Sciences is known as Spacelab 4. It is scheduled for launch in late 1985 and will remain aloft for seven days. This payload consists of 25 tentatively selected investigations combined into a comprehensive integrated exploration of the effects of acute weightlessness on living systems. An emphasis is placed on studying physiological changes that have been previously observed in manned space flight. This payload has complementary designs in the human and animal investigations in order to validate animal models of human physiology in weightlessness. The experimental subjects include humans, squirrel monkeys, laboratory rats, several species of plants, and frog eggs. The primary scientific objectives include study of the acute cephalic fluid shift, cardiovascular adaptation to weightlessness, including postflight reductions in orthostatic tolerance and exercise capacity, and changes in vestibular function, including space motion sickness, associated with weightlessness. Secondary scientific objectives include the study of red cell mass reduction, negative nitrogen balance, altered calcium metabolism, suppressed in vitro lymphocyte reactivity, gravitropism and photropism in plants, and fertilization and early development in frog eggs. The rationale behind this payload, the selection process, and details of the individual investigations are presented in this paper.

    Synchrotron spectroscopies offer unique advantages over conventional techniques, including higher detection sensitivity and molecular specificity, faster detection rate, and more in-depth information regarding the structural, electronic and catalytic properties under in-situ reaction conditions. Despite these advantages, synchrotron techniques are often underutilized or unexplored by the catalysis community due to various perceived and real barriers, which will be addressed in the current proposal. Since its establishment in 2005, the Synchrotron Catalysis Consortium (SCC) has coordinated significant efforts to promote the utilization of cutting-edge catalytic research under in-situ conditions. The purpose of the current renewal proposal is aimed to provide assistance, and to develop new sciences/techniques, for the catalysis community through the following concerted efforts: Coordinating the implementation of a suite of beamlines for catalysis studies at the new NSLS-II synchrotron source; Providing assistance and coordination for catalysis users at an SSRL catalysis beamline during the initial period of NSLS to NSLS II transition; Designing in-situ reactors for a variety of catalytic and electrocatalytic studies; Assisting experimental set-up and data analysis by a dedicated research scientist; Offering training courses and help sessions by the PIs and co-PIs.

    2016-06-01

    Data-based modeling of the magnetic field originating in the Earth's ionosphere is challenging due to the multiple timescales involved and the small spatial scales of some of the current systems, especially the equatorial electrojet (EEJ) that flows along the magnetic dip equator. The Dedicated Ionospheric Field Inversion (DIFI) algorithm inverts a combination of Swarm satellite and ground observatory data at mid- to low latitudes and provides models of the solar-quiet (Sq) and EEJ magnetic fields on the ground and at satellite altitude. The basis functions of these models are spherical harmonics in quasi-dipole coordinates and Fourier series describing the 24-, 12-, 8- and 6-h periodicities, as well as the annual and semiannual variations. A 1-D conductivity model of the Earth and a 2-D conductivity model of the oceans and continents are used to separate the primary ionospheric field from its induced counterpart. First results from the DIFI algorithm confirm several well-known features of the seasonal variability and westward drift speed of the Sq current systems. They also reveal a peculiar seasonal variability of the Sq field in the Southern hemisphere and a longitudinal variability reminiscent of the EEJ wave-4 structure in the same hemisphere. These observations suggest that the Sq and EEJ currents might be electrically coupled, but only for some seasons and longitudes and more so in the Southern hemisphere than in the Northern hemisphere.

  11. ACR testing of a dedicated head SPECT unit.

    Physics testing necessary for program accreditation is rigorously defined by the ACR. This testing is easily applied to most conventional SPECT systems based on gamma camera technology. The inSPira HD is a dedicated head SPECT system based on a rotating dual clamshell design that acquires data in a dual-spiral geometry. The unique geometry and configuration force alterations of the standard ACR physics testing protocol. Various tests, such as intrinsic planar uniformity and/or resolution, do not apply. The Data Spectrum Deluxe Phantom used for conventional SPECT testing cannot fit in the inSPira HD scanner bore, making (currently) unapproved use of the Small Deluxe SPECT Phantom necessary. Matrix size, collimator type, scanning time, reconstruction method, and attenuation correction were all varied from the typically prescribed ACR instructions. Visible spheres, sphere contrast, visible rod groups, uniformity, and root mean square (RMS) noise were measured. The acquired SPECT images surpassed the minimum ACR requirements for both spatial resolution (9.5 mm spheres resolved) and contrast (6.4 mm rod groups resolved). Sphere contrast was generally high. Integral uniformity was 4% and RMS noise was 1.7%. Noise appeared more correlated than in images from a conventional SPECT scanner. Attenuation-corrected images produced from direct CT scanning of the phantom and a manufacturer supplied model of the phantom demonstrated negligible differences.

    Two novel crystal growth syntheses dedicated to low solubility actinide-oxalate systems and adapted to glove box handling are described. These methods based on the use of precursors of either actinide metal or oxalic acid have been optimized on lanthanide systems (analogue of actinides(III)) and then assessed on real actinide systems. They allow the synthesis of several actinide oxalate single crystals, Am2(C2O4)3(H2O)3·xH2O, Th(C2O4)2·6H2O, M2+x[PuIV2-xPuIIIx(C2O4)5]·nH2O and M1-x[PuIII1-xPuIVx(C2O4)2·H2O]·nH2O. It is the first time that these well-known compounds are formed by crystal growth methods, thus enabling direct structural studies on transuranic element systems and acquisition of basic data beyond deductions from isomorphic (or not) lanthanide compounds. Characterizations by X-ray diffraction, UV-visible solid spectroscopy, demonstrate the potentialities of these two crystal growth methods to obtain oxalate compounds.

    Variable speed limits (VSLs) as a mean for enhancing road traffic safety are studied for decades to modify the speed limit based on the prevailing road circumstances. In this study the pros and cons of VSL systems and their effects on traffic controlling efficiency are summarized. Despite the potential effectiveness of utilizing VSLs, we have witnessed that the effectiveness of this system is impacted by factors such as VSL control strategy used and the level of driver compliance. Hence, the proposed approach called Intelligent Advisory Speed Limit Dedication (IASLD) as the novel VSL control strategy which considers the driver compliance aims to improve the traffic flow and occupancy of vehicles in addition to amelioration of vehicle's travel times. The IASLD provides the advisory speed limit for each vehicle exclusively based on the vehicle's characteristics including the vehicle type, size, and safety capabilities as well as traffic and weather conditions. The proposed approach takes advantage of vehicular ad hoc network (VANET) to accelerate its performance, in the way that simulation results demonstrate the reduction of incident detection time up to 31.2% in comparison with traditional VSL strategy. The simulation results similarly indicate the improvement of traffic flow efficiency, occupancy, and travel time in different conditions. PMID:24999493

  14. AMYPdb: A database dedicated to amyloid precursor proteins

    2008-01-01

    Background Misfolding and aggregation of proteins into ordered fibrillar structures is associated with a number of severe pathologies, including Alzheimer's disease, prion diseases, and type II diabetes. The rapid accumulation of knowledge about the sequences and structures of these proteins allows using of in silico methods to investigate the molecular mechanisms of their abnormal conformational changes and assembly. However, such an approach requires the collection of accurate data, which are inconveniently dispersed among several generalist databases. Results We therefore created a free online knowledge database (AMYPdb) dedicated to amyloid precursor proteins and we have performed large scale sequence analysis of the included data. Currently, AMYPdb integrates data on 31 families, including 1,705 proteins from nearly 600 organisms. It displays links to more than 2,300 bibliographic references and 1,200 3D-structures. A Wiki system is available to insert data into the database, providing a sharing and collaboration environment. We generated and analyzed 3,621 amino acid sequence patterns, reporting highly specific patterns for each amyloid family, along with patterns likely to be involved in protein misfolding and aggregation. Conclusion AMYPdb is a comprehensive online database aiming at the centralization of bioinformatic data regarding all amyloid proteins and their precursors. Our sequence pattern discovery and analysis approach unveiled protein regions of significant interest. AMYPdb is freely accessible [1]. PMID:18544157

  15. Rooftop Unitary Air Conditioner with Integral Dedicated Outdoor Air System

    Energy use of rooftop and other unitary air-conditioners in commercial applications accounts for about 1 quad (10{sup 15} Btu) of primary energy use annually in the U.S. [Reference 7]. The realization that this cooling equipment accounts for the majority of commercial building cooled floorspace and the majority also of commercial building energy use has spurred development of improved-efficiency equipment as well as development of stricter standards addressing efficiency levels. Another key market driver affecting design of rooftop air-conditioning equipment has been concern regarding comfort and the control of humidity. Trends for increases in outdoor air ventilation rates in certain applications, and the increasing concern about indoor air quality problems associated with humidity levels and moisture in buildings points to a need for improved dehumidification capability in air-conditioning equipment of all types. In many cases addressing this issue exacerbates energy efficiency, and vice versa. The integrated dedicated outdoor air system configuration developed in this project addresses both energy and comfort/humidity issues.

    The details of the payload and the experiments in Spacelab 4, the first Spacelab mission dedicated entirely to the life sciences, are discussed. The payload of Spacelab 4, carried in the bay of the Shuttle Orbiter, consists of 25 tentatively selected investigations combined into a comprehensive integrated exploration of the effects of acute weightlessness on living systems. The payload contains complementary designs in the human and animal investigations in order to validate animal models of human physiology in weightlessness. Animals used as experimental subjects will include squirrel monkeys, laboratory rats, several species of plants, and frog eggs. The main scientific objectives of the investigations include the study of the acute cephalic fluid shift, cardiovascular adaptation to weightlessness, including postflight reductions in orthostatic tolerance and exercise capacity, and changes in vestibular function, including space motion sickness, associated with weightlessness. Other scientific objective include the study of red cell mass reduction, negative nitrogen balance, altered calcium metabolism, suppressed in vitro lymphocyte reactivity, gravitropism and photropism in plants, and fertilization and early development in frog eggs.

  17. Rural model dedicated education unit: partnership between college and hospital.

    PubMed

    Harmon, Lisa M

    2013-02-01

    This article describes the pilot project development of a rural model Dedicated Education Unit (DEU) by a rural college nursing program and a rural hospital to increase student nurses' confidence and proficiency and improve recruitment of prepared rural staff nurses. Traditionally, for economies of scale, most student clinical rotations occurred in urban settings with the number of students per clinical instructor allowed by the state board of nursing. College budget constraints negated the placement of fewer than this mandated maximum number of students in a rural hospital with a clinical instructor; moreover, rural hospitals could not accommodate 10 students at one time. Rural nursing students were anxious in the urban settings, and this anxiety precluded learning in many instances. Rural hospitals face higher registered nurse vacancies than urban centers. Of the nurses applying for open positions, many were not prepared for the demands of rural nursing, resulting in increased turnover and high orientation costs. The rural model DEU addressed issues of both the nursing program and the hospital. The design and development of the rural model DEU and the advantages of the partnership for the college nursing program and the hospital are discussed. Initial outcomes and serendipitous findings from the pilot project are also discussed.

    The worldwide emergence of antibiotic resistances and the drying up of the antibiotic pipeline have spurred a search for alternative or complementary antibacterial therapies. Bacteriophages are bacterial viruses that have been used for almost a century to combat bacterial infections, particularly in Poland and the former Soviet Union. The antibiotic crisis has triggered a renewed clinical and agricultural interest in bacteriophages. This, combined with new scientific insights, has pushed bacteriophages to the forefront of the search for new approaches to fighting bacterial infections. But before bacteriophage therapy can be introduced into clinical practice in the European Union, several challenges must be overcome. One of these is the conceptualization and classification of bacteriophage therapy itself and the extent to which it constitutes a human medicinal product regulated under the European Human Code for Medicines (Directive 2001/83/EC). Can therapeutic products containing natural bacteriophages be categorized under the current European regulatory framework, or should this framework be adapted? Various actors in the field have discussed the need for an adapted (or entirely new) regulatory framework for the reintroduction of bacteriophage therapy in Europe. This led to the identification of several characteristics specific to natural bacteriophages that should be taken into consideration by regulators when evaluating bacteriophage therapy. One important consideration is whether bacteriophage therapy development occurs on an industrial scale or a hospital-based, patient-specific scale. More suitable regulatory standards may create opportunities to improve insights into this promising therapeutic approach. In light of this, we argue for the creation of a new, dedicated European regulatory framework for bacteriophage therapy.

    In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program (SSP). The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information, developed in this program, is based on clinical practice guidelines produced by the FNCLCC and the twenty French cancer centres, the National League against Cancer, The National Cancer Institute, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and caregivers. The information and dialogue handbook SOR SAVOIR PATIENT Vivre pendant et après un cancer reporting on the psychological aspects of cancer was worked out and published on the Web in 2005. The guide aims to provide cancer patients with support and advice about the psychological impact of the disease. It provides information on the possible personal consequences of the disease and treatments, in every domain: psychological, emotional, interpersonal, familial or professional. Patients are also advised of the emotional challenges associated with cancer, of the support they may expect at every stage of the disease, from diagnosis to treatment, and of psychological outcome after the disease is over. The document also provides healthcare professionals with a valuable, concise source of validated information on the psychological aspects of cancer, thus facilitating communication between carers and patients. Information provided in the present article has been selected from the information and dialogue handbook SOR SAVOIR

  1. Design study of a cardiac-dedicated PET system

    NASA Astrophysics Data System (ADS)

    Peng, Hao

    2015-04-01

    The work studies the feasibility of developing a cardiac-dedicated PET system using Monte Carlo simulation tools. The proposed system comprises a dual-panel geometry and both panels utilize fine crystal elements (~2-3 mm) to help improve high spatial resolution. The system performances were studied with respect to photon detection sensitivity, count-rate performances, spatial resolution, depth-of-interaction (DOI) capability, and potential contrast recovery improvement due to time-of-flight (TOF). For a 2:3 dual panel configuration (front panel: 24.0×18.0 cm2 and back panel: 36.0×27.0 cm2), the system is able to achieve a peak photon sensitivity of ~13.0% at the location of the heart. For count-rate performances, the system is able to yield a continuous increase of noise equivalent count rate (NECR) as a function of the total activity of radiotracers between 10 mCi and 50 mCi. When crystal elements of 2×2×20 cm3 are deployed in the front panel and crystal elements of 3×3×20 cm3 are deployed in the back panel, the proposed system is not only able to revolve 2 mm diameter spheres in the image slices parallel to the panels but also demonstrates good resolution uniformity of less than 5%. On the other hand, significant resolution degradation occurs in the direction perpendicular to the panels due to the following two factors: limited angular coverage and finite DOI resolution. Such degradation was quantitatively analyzed for five different DOI resolutions (0 mm, 2.5 mm, 5 mm, 10 mm and 20 mm), as well as three different crystal configurations. Finally, the contrast study with a heart-like phantom (comprising lumen, aortic wall, myocardium and small lesions) indicates that TOF capability (time resolution: 250-500 ps) does not significantly improve image quality and lesion detectability, in terms of contrast-to-noise ratio (CNR).

    Prionas, Nicolas D.; Huang, Shih-Ying; Boone, John M.

    2011-02-15

    Purpose: The current study aimed to experimentally identify the optimal technique factors (x-ray tube potential and added filtration material/thickness) to maximize soft-tissue contrast, microcalcification contrast, and iodine contrast enhancement using cadaveric breast specimens imaged with dedicated breast computed tomography (bCT). Secondarily, the study aimed to evaluate the accuracy of phantom materials as tissue surrogates and to characterize the change in accuracy with varying bCT technique factors. Methods: A cadaveric breast specimen was acquired under appropriate approval and scanned using a prototype bCT scanner. Inserted into the specimen were cylindrical inserts of polyethylene, water, iodine contrast medium (iodixanol, 2.5 mg/ml), and calcium hydroxyapatite (100 mg/ml). Six x-ray tube potentials (50, 60, 70, 80, 90, and 100 kVp) and three different filters (0.2 mm Cu, 1.5 mm Al, and 0.2 mm Sn) were tested. For each set of technique factors, the intensity (linear attenuation coefficient) and noise were measured within six regions of interest (ROIs): Glandular tissue, adipose tissue, polyethylene, water, iodine contrast medium, and calcium hydroxyapatite. Dose-normalized contrast to noise ratio (CNRD) was measured for pairwise comparisons among the six ROIs. Regression models were used to estimate the effect of tube potential and added filtration on intensity, noise, and CNRD. Results: Iodine contrast enhancement was maximized using 60 kVp and 0.2 mm Cu. Microcalcification contrast and soft-tissue contrast were maximized at 60 kVp. The 0.2 mm Cu filter achieved significantly higher CNRD for iodine contrast enhancement than the other two filters (p=0.01), but microcalcification contrast and soft-tissue contrast were similar using the copper and aluminum filters. The average percent difference in linear attenuation coefficient, across all tube potentials, for polyethylene versus adipose tissue was 1.8%, 1.7%, and 1.3% for 0.2 mm Cu, 1.5 mm Al, and 0.2 mm

  14. Airborne Radar Observations of Hurricane Georges during Landfall over the Dominican Republic

    NASA Technical Reports Server (NTRS)

    Geerts, B.; Heymsfield, G.; Tian, L.

    1999-01-01

    On 22 September 1998 hurricane Georges made landfall on the Dominican Republic (DR). Georges cost the DR at least 500 lives, made more than 155,000 people homeless and caused extensive damage to the country's main industries, tourism and agriculture. There was considerable wind damage, with wind gusts up to 58 m/s in Santa Domingo on the south coast, but most of the damage and deaths resulted from mudslides and the flooding of rivers. While this may have been the worst natural disaster to strike the DR, the sustained rapid storm movement saved the island from worse damage. Georges had previously affected several islands in the Lesser Antilles and Puerto Rico, but it had retained much of its circulation strength. Forty raingauge stations across the DR measured rainfall totals from Georges between 0.7 and 41 cm, the latter at the capital Santo Domingo, located on the south coast. At Herrera the maximum 1 h rainfall rate was 72 mm/h. It is suspected that much higher rain rates occurred in DR's mountainous interior. Before landfall the eye was clearly evident in satellite imagery. When the eye moved over southeastern DR, it filled rapidly, and the cloud top height decreased in all storm sectors except in the southern inflow sector, where a long-lived MCS, with a diameter larger than that of the eyewall, slowly became enwrapped in the hurricane circulation. The eye closure was most rapid between 16-18 UTC, when the eyewall circulation felt the mountainous terrain of the Cordillera Central, which rises up to 3,093 m. The estimated central pressure increased from 962 hPa at 15 UTC to 986 hPa at 03Z on 23 Sept, and the maximum sustained surface wind speed decreased from 54 to 36 in s-1 during the same period. The island of Hispaniola has a cross-track width of about 250 km, much wider than the diameter of the eyewall anvil (about 100 km before landfall). So the event can truly be considered to be a landfalling case, even though Georges recovered after crossing Hispaniola

  15. Bowtie filters for dedicated breast CT: Theory and computational implementation

    SciTech Connect

    Kontson, Kimberly Jennings, Robert J.

    2015-03-15

    Purpose: To design bowtie filters with improved properties for dedicated breast CT to improve image quality and reduce dose to the patient. Methods: The authors present three different bowtie filters designed for a cylindrical 14-cm diameter phantom with a uniform composition of 40/60 breast tissue, which vary in their design objectives and performance improvements. Bowtie design #1 is based on single material spectral matching and produces nearly uniform spectral shape for radiation incident upon the detector. Bowtie design #2 uses the idea of basis material decomposition to produce the same spectral shape and intensity at the detector, using two different materials. Bowtie design #3 eliminates the beam hardening effect in the reconstructed image by adjusting the bowtie filter thickness so that the effective attenuation coefficient for every ray is the same. All three designs are obtained using analytical computational methods and linear attenuation coefficients. Thus, the designs do not take into account the effects of scatter. The authors considered this to be a reasonable approach to the filter design problem since the use of Monte Carlo methods would have been computationally intensive. The filter profiles for a cone-angle of 0° were used for the entire length of each filter because the differences between those profiles and the correct cone-beam profiles for the cone angles in our system are very small, and the constant profiles allowed construction of the filters with the facilities available to us. For evaluation of the filters, we used Monte Carlo simulation techniques and the full cone-beam geometry. Images were generated with and without each bowtie filter to analyze the effect on dose distribution, noise uniformity, and contrast-to-noise ratio (CNR) homogeneity. Line profiles through the reconstructed images generated from the simulated projection images were also used as validation for the filter designs. Results: Examples of the three designs are

    2015-01-01

    Background Wikis may give clinician communities the opportunity to build knowledge relevant to their practice. The only previous study reviewing a set of health-related wikis, without specification of purpose or audience, globally showed a poor reliability. Objective Our aim was to review medical wiki websites dedicated to clinical practices. Methods We used Google in ten languages, PubMed, Embase, Lilacs, and Web of Science to identify websites. The review included wiki sites, accessible and operating, having a topic relevant for clinical medicine, targeting physicians or medical students. Wikis were described according to their purposes, platform, management, information framework, contributions, content, and activity. Purposes were classified as “encyclopedic” or “non-encyclopedic”. The information framework quality was assessed based on the Health On the Net (HONcode) principles for collaborative websites, with additional criteria related to users’ transparency and editorial policy. From a sample of five articles per wikis, we assessed the readability using the Flesch test and compared articles according to the wikis’ main purpose. Annual editorial activities were estimated using the Google engine. Results Among 25 wikis included, 11 aimed at building an encyclopedia, five a textbook, three lessons, two oncology protocols, one a single article, and three at reporting clinical cases. Sixteen wikis were specialized with specific themes or disciplines. Fifteen wikis were using MediaWiki software as-is, three were hosted by online wiki farms, and seven were purpose-built. Except for one MediaWiki-based site, only purpose-built platforms managed detailed user disclosures. The owners were ten organizations, six individuals, four private companies, two universities, two scientific societies, and one unknown. Among 21 open communities, 10 required users’ credentials to give editing rights. The median information framework quality score was 6 out of 16

    2010-08-15

    Purpose: To investigate the glandular dose magnitudes and characteristics resulting from image acquisition using a dedicated breast computed tomography (BCT) clinical prototype imaging system. Methods: The x-ray spectrum and output characteristics of a BCT clinical prototype (Koning Corporation, West Henrietta, NY) were determined using empirical measurements, breast phantoms, and an established spectrum model. The geometry of the BCT system was replicated in a Monte Carlo-based computer simulation using the GEANT4 toolkit and was validated by comparing the simulated results for exposure distribution in a standard 16 cm CT head phantom with those empirically determined using a 10 cm CT pencil ionization chamber and dosimeter. The computer simulation was further validated by replicating the results of a previous BCT dosimetry study. Upon validation, the computer simulation was modified to include breasts of varying sizes and homogeneous compositions spanning those encountered clinically, and the normalized mean glandular dose resulting from BCT was determined. Using the system's measured exposure output determined automatically for breasts of different size and density, the mean glandular dose for these breasts was computed and compared to the glandular dose resulting from mammography. Finally, additional Monte Carlo simulations were performed to study how the glandular dose values vary within the breast tissue during acquisition with both this BCT prototype and a typical craniocaudal (CC) mammographic acquisition. Results: This BCT prototype uses an x-ray spectrum with a first half-value layer of 1.39 mm Al and a mean x-ray energy of 30.3 keV. The normalized mean glandular dose for breasts of varying size and composition during BCT acquisition with this system ranges from 0.278 to 0.582 mGy/mGy air kerma with the reference air kerma measured in air at the center of rotation. Using the measured exposure outputs for the tube currents automatically selected by the

    Rodway, George W

    2007-01-01

    Alpinist and scientist George Ingle Finch was invited on the 1921 British Mount Everest Reconnaissance, but events conspired to keep him away from Everest until the 1922 British expedition to the mountain. Very little is known in the English-speaking world about the 1925 German language book Der Kampf um den Everest, written by Finch and covering the Everest attempts of the 1920s, as it was never published in English. Additionally, very little has been published from Finch's personal diaries of the 1922 Everest climb. The object of this work is to utilize translated sections of Der Kampf um den Everest and passages from Finch's 1922 Everest diaries to create some sense of George Finch's personal perspective of the 1922 Everest attempt. This historic climb was the first mountaineering expedition to breach the 8000-m barrier when two separate parties, one climbing with supplementary oxygen and the other without, established new terrestrial altitude records.

  1. Distribution, abundance and benthic-pelagic coupling of suspended hydroids on Georges Bank1, 2

    NASA Astrophysics Data System (ADS)

    Concelman, Stephanie; Bollens, Stephen M.; Sullivan, Barbara K.; Madin, Laurence P.; Horgan, Erich; Butler, Mari; van Keuren, Donna

    Clytia spp. hydroids (Phylum Cnidaria), typically attached to a substrate during their asexual, polyp stage, have been found in significant numbers within the mesozooplankton on Georges Bank, North Atlantic Ocean. We examined unpublished historical records of the 1939-1941 cruises of the R/V Atlantis and obtained samples at four-study sites on Georges Bank in June/July 1995 in an attempt to (1) quantify the planktonic and benthic distributions of hydroids on Georges Bank, and (2) determine the coupling between benthic and pelagic habitats of this population. We found that planktonic hydroids have a patchy distribution, varying both spatially and temporally (most abundant in summer months, absent in winter). In 1939-1941 the planktonic hydroids were most broadly distributed following a spring (1940) with strong wind events; hydroids were absent from all samples in 1941. In 1995 we found the highest abundance of planktonic Clytia spp. hydroids (6213.5±1343.6 hydranths m -3) in the central crest of the bank, "downstream" in the Georges Bank circulation pattern from sites along the northeast peak of the Bank where large populations of benthic Clytia spp. hydroids were found (up to 6465 hydranths m -2). Our plankton sampling did not show significant numbers of hydroids in the water column at the Northeast peak sites, indicating that large numbers of planktonic hydroids are not being introduced into the Bank's circulation patterns from off-Bank sites to the northeast (e.g. Scotian shelf). The source population for planktonic hydroids found in the central region of the Bank is most likely the benthic habitats on the northeast peak of the Bank. We hypothesize, and our limited data suggest, that hydroids are detached from the benthos by storm action or other disturbance, advected clockwise with the mean residual circulation, and concentrated and retained in the central, low-advective region of the Bank.

    2013-04-01

    George Kelly's "The psychology of personal constructs" put forward a new psychology that viewed people as actively constructing and anticipating their worlds. This paper considers personal construct theory and its philosophy; personal construct assessment techniques; the personal construct view of psychological disorder and its treatment; and the wide range of other applications of personal construct theory. It is concluded that personal construct psychology remains a radical approach over half a century after Kelly published his magnum opus.

Retreat of the northern margin of the George VI Ice Shelf has been observed previously, but the Wilkins Ice Shelf was thought to be stable. We investigated the positions of the northern fronts of these shelves from the literature and looked for changes on 1974 Landsat and 1992 and 1995 European remote-sensing satellite (ERS) synthetic aperture radar images. Our investigation shows that the northern George VI Ice Shelf lost a total of 906 km2 between 1974 and 1992, and an additional 87 km2 by 1995. The northern margin of the Wilkins Ice Shelf lost 796 km2 between 1990 and 1992, and another 564 km2 between 1992 and 1995. Armadas of tabular icebergs were visible in front of this shelf in the ERS images. These two ice shelves mark the southernmost documented conspicuous retreat of ice-shelf margins.

    The biography of the physician general Alain Jean Georges (1946-2012) shows the exceptional career of a military physician-clinical pathologist specialized in tropical medicine and educated at the Navy Health School in Bordeaux and the Pharo School in Marseille. He completed his education at the Institut Pasteur de Paris in courses still conducted in the spirit of those taught by Louis Pasteur. In 1979, he became director of the Pasteur Institute of Bangui, following in the steps of Eugène Jamot, in the long tradition of military doctors from the Institut Pasteur overseas network committed to a career in Africa. For more than 12 years, Alain Georges directed the Pasteur Institute of Bangui, one of the last citadels of French postcolonial military medicine, in a very personal and charismatic style. He was thus a pioneer in research about both AIDS in Africa and hemorrhagic fevers. His methods were widely misunderstood later as the traditional networks of French biomedical research in its former African colonies modernized and opened internationally, including to national elites. Alain Georges was probably one of the last important figures of the golden age of French colonial medicine.

    leaders of Romanian physics. It is in recognition of his contribution to physics, especially nuclear physics, as well as his work for Romanian science that this School is organized in his honour, on the occasion of his 80th birthday. I cannot finish this short account without mentioning the person that accompanied Aurel Sandulescu through all his life, his wife of more than fifty years, Violeta. She also was an exceptional person. In her youth she was a very dedicated sporty girl, very athletic, very courageous, very fair and, above all, very generous. These qualities remained with her throughout her life. With deep sorrow I learnt that she passed away three months ago, still youthful and enthusiastic. R J Liotta

    Dedicated Education Units optimize the expertise of staff nurses to provide clinical instruction to nursing students, thereby creating a need to prepare staff nurses for the teaching role and educate them about clinical teaching strategies. A curriculum to educate Dedicated Education Unit staff nurses in the art of clinical instruction was created to fill this gap in staff development. This article describes the development of an innovative, interactive, evidence-based curriculum to prepare Dedication Education Unit staff nurses and strengthen an academic-practice partnership.

    Lacustrine alkenone records have potential to be valuable sedimentary archives of continental paleotemperature. However, the use of the Uk37 paleotemperature proxy in lake environments is constrained by the genetic diversity of lake-dwelling, alkenone-producing haptophytes. Previous research in Lake George, ND revealed the presence of two alkenone-producing haptophyte species (Hap-A and Hap-B) whose individual contributions to the alkenone sediment record are unknown. To gauge the seasonal abundance of these multiple haptophyte species we used a high-throughput DNA sequencing approach. We collected bi-weekly water samples at three different depths in the photic zone (0m, 5m, 10m) from late April through bloom termination in early August. Using 18S rRNA gene sequences to determine species identity, we compared water sample microbial communities with water sample alkenone signatures. Additionally, we cultivated Lake George haptophyte isolates in pure and mixed cultures to define their Uk37 temperature calibrations. During the course of the seasonal cycle, total concentrations of alkenones demonstrated a distinct peak approximately five weeks after their first appearance in the water column. The peak bloom water samples were characterized by abundant tetraunsaturated (C37:4) alkenones in resemblance to the Lake George sediment records. As the bloom declined, the C37:4 alkenones declined in abundance. This variation in water column alkenone signature was reflected in the relative abundance of Hap-A and Hap-B, with Hap-B dominating during bloom peak. Our culture work determined that these multiple haptophyte isolates required individual Uk37 calibrations that differ from the Lake George in situ Uk37 calibration. Lake George sediment alkenone records are therefore composites of multiple, co-occurring haptophyte temperature records. This study is the first next-generation DNA sequencing effort to analyze the microbial community during a haptophyte bloom, and together with
