  1. Aldo Leopold: An American Prophet (United States)

    Frese, Stephen J.


    In 1935, Aldo Leopold bought an abandoned farm in the sand counties along the Wisconsin River near Baraboo. Leopold sensed promise in the land, and with his wife and five children nursed the land back to health. They cleaned out the chicken coop and affectionately called their new family retreat "The Shack." Leopold kept detailed notes during the…

  4. The 2012 CASPER Physics Circus (United States)

    Carmona Reyes, Jorge; Land-Zandstra, Anne; Cheng, Joyce; Douglass, Angela; Harris, Brandon; Zhang, Zhuanhao; Chen, Mudi; Matthews, Lorin; Hyde, Truell


    The CASPER Physics Circus is one component of a CASPER ongoing educational outreach initiative known as the CASPER Seamless Pathway. The Physics Circus is funded by the United States Department of Education and is designed to increase interest in, engagement with, and understanding of science, technology, engineering and mathematics (STEM) within students in grades 6 through 12. The program's material and curriculum is aligned with both TEKS (Texas Essentials Knowledge and Skills) and National Science and Mathematics Standards, with its components (theatre, hands-on exhibitions, game show, professional development and curriculum) reinforcing these goals in a creative and entertaining format. Pre- and post-assessments measuring both content understanding and attitude towards science were conducted for a representative sample of the cohort and the analyzed data will be presented. The role the Circus plays within CASPER's Seamless Pathway will also be discussed along with other current CASPER programs including its High School Scholars program, CASPER's Interns program and CASPER NSF funded REU/RET programs for college undergraduates and K-12 teachers.

  5. The CASPER Virtual Physics Circus (United States)

    Carmona-Reyes, Jorge; Harris, Brandon; Chen, Mudi; Matthews, Lorin; Hyde, Truell


    CASPER's Virtual Physics Circus (VPC) is based on the long-running CASPER Physics Circus and is the most recent component in CASPER's ``Seamless Pathway'' educational outreach initiative. The VPC was developed by an interdisciplinary group of physicists, web-designers and educators and employs both web and video game environments to provide students and teachers with engaging, fast-paced educational activities. Access to an integrated curriculum and video library, aligned to both the TEKS (Texas Essentials Knowledge and Skill) and the National Science and Mathematics Standards, is also part of the VPC package. In this talk an initial beta-test of the VPC, conducted for a central Texas independent school district, will be discussed. Future plans for both expansion and translation into Spanish will also be discussed.

  7. CASPER: Concordia Atmospheric SPectroscopy of Emitted Radiation (United States)

    de Petris, M.; Catalano, A.; de Gregori, S.; Lamagna, L.; Lattanzi, V.; Luzzi, G.; Maoli, R.; Melchiorri, A.; Melchiorri, F.; Savini, G.; Vetrani, G. G.; Battistelli, E. S.; Valenziano, L.; Mandolesi, N.; Villa, F.; Cuttaia, F.; Ade, P. A. R.; Mauskopf, P.; Orlando, A.; Encrenaz, P.; Pardo, J. R.; Cernicharo, J.

    CASPER (Concordia Atmospheric SPectroscopy of Emitted Radiation) is a spectrometer proposed for installation at Dome C, devoted to measurements of atmospheric emission in the spectral region between 180 μm and 3 mm (3 55 cm-1). This instrument will be able to perform continuous spectral sampling at different altitudes at angular scales of 1°. From the recorded data it is possible to extract atmospheric transmittance within 1% in the whole wide operating band, together with water vapour content and O{2} and O{3} concentrations. CASPER will allow us to characterize the site for future FIR/mm telescopes. Atmospheric data recorded by CASPER will allow for correction of astrophysical and cosmological observations without the need for telescope-specific procedures and further loss of observation time with more precision in the observations themselves. Calibration of ground-based telescopes on known sky sources is strongly affected by atmospheric absorption. CASPER has this as its primary goal. The spectrometer is based on a Martin-Puplett interferometer. Two data sampling solutions will be performed: phase modulation & fast scan strategy. Sky radiation is collected towards the interferometer by an optical setup that allows the field of view, to explore the full 0° div 90° range of elevation angles. With a low spurious polarization instrument, monitoring of polarized atmospheric contribution will be possible.

  8. Leopold Infeld: Hope Lost, Hope Regained

    International Nuclear Information System (INIS)

    Richmond, T.


    This lecture was delivered by the author of the book ''Konin: A Quest'', which describes the history of the Jewish community in the small town of Konin in central Poland. Unable at that time to find employment in any university in Poland, Leopold Infeld served there as headmaster of a Jewish co-educational high school between 1922 and 1924. Drawing on his own researches as well as Infeld's memoir ''Quest: The Evolution of a Scientist'', the author presents Infeld within the context of his family's social and religious background, and his ''exile'' years as a teacher in Konin, evoking a little-known period in the scientist's life.

  9. Development of Active Learning Curriculum for CASPER's Microgravity Drop Tower (United States)

    Carmona-Reyes, Jorge; Wang, Li; York, Judy; Matthews, Lorin; Laufer, Rene; Cook, Mike; Schmoke, Jimmy; Hyde, Truell


    As CASPER's new drop tower comes on line, plans for correlated educational research curricula are underway. CASPER's educational research team is working on developing curricula specific to the CASPER drop tower, modeled on a contest currently in use by (BEST) Robotics Inc. within central Texas independent school districts. The curricula integrates age specific use of computer programming software packages such as ``Scratch'' with industry standard communication protocols and augmented reality applications. Content is constructed around an earth and space science framework, covering subjects such as stars and galaxies, matter and energy, fusion and fission at a middle school level. CASPER faculty are partnering with the Region 12 Service Center; this combination provides a wide range of expertise that includes professional development, pedagogical methods, computational thinking in addition to microgravity and space science research expertise. The details of this work will be presented and samples of the manner in which it is impacting the CASPER research and educational outreach partnership will be discussed.

  10. Casper or 'the cabinet of horrors'. (United States)

    Cavalli, Alessandra


    This paper is an account of a four-times-a-week analysis with a very deprived, feral-like child. The author, who has come to understand feral children as very deprived children, turns to an historical account written in 1826 by Anselm von Feuerbach, the jurist who was asked to make enquiries into the identity of a savage and mysterious boy, Kaspar Hauser. The author describes how she has made use of the observations and thoughts of Anselm von Feurbach in her attempts to process her own thoughts and reflections around the unfolding clinical material and how the exploration of the differences and similarities between Casper and Kaspar Hauser helped her to gradually grasp the psychological essence of the patient. The question of an appropriate reading of the clinical material for theoretical purposes remains open.

  12. Life as a sober citizen: Aldo Leopold's Wildlife Ecology 118 (United States)

    Theiss, Nancy Stearns

    This historic case study addressed the issue of the lack of citizen action toward environmentally responsible behavior. Although there have been studies regarding components of environmental responsible behavior [ERB], there has been little focus on historic models of exemplary figures of ERB. This study examined one of the first conservation courses in the United States, Wildlife Ecology 118, taught by Aldo Leopold (1887--1948) for 13 years at the University of Wisconsin. Today, Aldo Leopold is recognized as an exemplary conservationist whose land ethic is cited as providing the ecological approach needed for understanding the complex issues of modern society. The researcher conjectured that examination of one of the first environmental education courses could support and strengthen environmental education practices by providing a heuristic perspective. The researcher used two different strategies for analysis of the case. For Research Question One---"What were Leopold's teaching strategies in Wildlife Ecology 118?"---the researcher used methods of comparative historical analysis. The researcher examined the learning outcomes that Leopold used in Wildlife Ecology 118 and compared them against a rubric of the Four Strands for Environmental Education (North American Association for Environmental Education [NAAEE], 1999). The Four Strands for Environmental Education are the current teaching strategies used by educators. The results indicated that Wildlife Ecology 118 scored high in Knowledge of Processes and Systems and Environmental Problem Solving strands. Leopold relied on historic case examples and animal biographies to build stories that engaged students. Field trips gave students practical experience for environmental knowledge with special emphasis on phenology. For Research Question Two---"What was the context of the lessons in Wildlife Ecology 118?"---the researcher used environmental history methods for analysis. Context provided the knowledge and

  13. An Ecological Probe into Land Ethics by Aldo Leopold

    Institute of Scientific and Technical Information of China (English)



    Aldo Leopold has gained considerable repute as the initiator of eco-conservationism and been globally known as the father of American wilderness governance.“Land ethics”,which possesses paramount importance to eco-systems,is brought forth in his Sand Country Almanac.This thesis mainly touches upon the engendering,contents and significance of the thoughts to nowadays society by means of which the contemporary values of ecological civilization embodied in“land ethics”can be concluded provokingly.

  14. ["... my friend Leopold was percussing her through her bodice...". Leopold von Auenbrugger in Sigmund Freud's dream of Irma's injection]. (United States)

    Reicheneder, Johann Georg


    This paper provides a psychoanalytic interpretation of an element in the Irma dream that Freud had ignored in his own interpretation. The allusion to Leopold von Auenbrugger, the originator of percussion as a method of clinical investigation, which appears in the manifest dream reflects Freud's hopes and fears about how his Interpretation of Dreams and the new human science established there would be received by his medical colleagues.

  15. Aldo Leopold on Education: An Educator and His Land Ethic in the Context of Contemporary Environmental Education. (United States)

    Callicott, J. Baird

Leopold's views on education and Leopold as an educator are discussed. (Author/JN)

  16. Austrian Painter Leopold Kupelwieser and Bishop Josip Juraj Strossmayer

    Directory of Open Access Journals (Sweden)

    Ljerka Dulibić


    Full Text Available All 20th-century chronologies of the collector’s activity of Bishop Josip Juraj Strossmayer (1815-1905 and overviews of the evolution of today’s Strossmayer’s Gallery of Old Masters at the Croatian Academy of Sciences and Arts mention the bishop’s cooperation with the Austrian Nazarene painter Leopold Kupelwieser (1796-1862, father of Paul Kupelwieser, the former owner of the Brijuni islands. This episode from the “prehistory” of Strossmayer’s Gallery has hitherto been known only as a brief notice repeated in almost identical formulations: “In 1857, the bishop sent the first larger group of paintings to Vienna in order to be restored under the supervision of painter Leopold Kupelwieser.” Research of archival documents mentioning the cooperation between Bishop Strossmayer and painter Kupelwieser has now been complemented with an overview of Kupelwieser’s activity in Croatia, with an aim of promoting the preservation and evaluation of this segment of his painting oeuvre. Besides paintings ordered by Strossmayer (presently at the Diocesan Museum of Zagreb, Kupelwieser produced two paintings for Croatian churches independently of his cooperation with the bishop (for the church of St Stephen of Hungary, today’s church of the Immaculate Conception of the Blessed Virgin Mary in Nova Gradiška, and for the chapel of St Peter and Paul in Dvor na Uni. Two more paintings are preserved on the Brijuni islands that do not directly belong to Kupelwieser’s oeuvre yet are closely linked to him.

  20. Polish Decadence: Leopold Staff's Igrzysko in the European Context

    Directory of Open Access Journals (Sweden)

    Julia Przybos


    expression. It is my hypothesis that taken out of its secular context, religious revisionism of the kind practiced by French decadents may be seen as shocking transgression in a fiercely catholic country like Poland. In the country that lost its independence in 1794 and was ever since seeking to regain it, Catholic Church was perceived as an essential ally in the struggle against main occupying powers: Orthodox Russia, and Protestant Prussia. In the course of the 19th century Catholicism and patriotism had been effectively fused in Polish national conscience. In this charged political context a Polish author revisiting Church dogma or tradition was at risk of being perceived not only as a religious outcast but also as a traitor to the cause of Polish independence. To test my hypothesis I propose to examine Igrzysko (Game, a forgotten play by Leopold Staff. Admired today chiefly as a poet, the young Staff wrote Igrzysko in Poland after a long sojourn in Paris where he had lived among the international crowd of fin de siècle writers and artists. The play was first produced in Lemberg in 1909 and after a few performances vanished forever from Polish theatrical repertoire. Leopold Staff's play is set in ancient Rome and depicts tribulations of an actor who, while impersonating a Christian awaiting crucifixion, converts to Christianity. In his play, Staff revives the legend of Saint Genesius, an actor in Arles who died a martyr's death in 286 under Diocletian. In Spain, Saint Genesius's legend inspired Lope de Vega who wrote Acting is Believing (Lo fingido verdadero, 1607. In France, it was the source for Jean Rotrou's Saint Genest (1646. All told, the legend of Genesius is a popular theme for artists who wish to explore the distinction between art and life. An important addition to this old tradition, Staff's play contains, however, a decadent and potentially scandalous twist. Unlike in Acting is Believing and Saint Genest, the protagonist's conversion is very short

  1. A Poet in Scientist’s Uniform: Leopold Senghor

    Directory of Open Access Journals (Sweden)

    Iryna Satygo


    Full Text Available The article is devoted to the study of the scientific views of Leopold Senghor (1906–2001, the Senegalese poet, thinker and statesman, the president of Senegal (1960–1980, a member of the French Academy (1983, the most influential writer of the West-African literary region, on the figurativeness and rhythmics of the African poetical tradition.The article emphasizes on therhythmic images, including “analogical images” and a special African rhythm – tetrameter as a specific feature of the West-African folk poetry. It is shown that the ternary African rhythms during the song performance of traditional verses create a “silent” basic rhythm, a missed sign of traditional African singing poem. It is also stressed that Senghor’s Négritude conception became an important culturological paradigm for the African poetry of the XX century. One of the basic principles of the Négritude was proclaimed the return to the African sources, and consequently, traditional African values, became source of inspiration of the African artists. It is confirmed that the rhythm acts the major part in the communication of the Africans and immanently exists in all African culture. Négritude’s existentials as rhythm and analogical image were reasoned by Senghor as the main features of the African culture.

  3. [St Leopold Mandić: a cripple who became a charismatic confessor]. (United States)

    Vlah, Anđelko


    The first part of this article presents in detail the life of the Croatian Capuchin St Leopold Bogdan Mandić (Herceg Novi, 1866 - Padova, 1942). Follows a discussion about the relation between his disability and medicine, including paranormal phenomena recorded during his life on earth. The article concludes with a note that the Holy See has recognised an outstanding number of healing miracles performed by Leopold Mandić, and describes the two most fascinating. The extraordinary attendance to his funeral in 1942, beatification in 1977, and canonisation in 1983 evidence that this saint has been one of the most revered personalities in the recent history of the Catholic Church.

  4. [Drugs for young Mozart. Medical treatment of Wolfgang as a child by his father Leopold Mozart]. (United States)

    Bankl, H C; Reiter, C; Bankl, H


    Leopold Mozart (1719-1787), father of Wolfgang Amadé, had profound medical knowledge and was a passionate medical dilettante. As long as the young Mozart lived with his father and travelled on his concert tours with him, Leopold cared for his son in medical matters. Doctors were only consulted occasionally. In the extensive correspondence of Mozart's father drugs and treatments used for Wolfgang Amadé are reported in detail. This represents a reliable description of the pharmacological therapies of the late 18th century. The mentioned drugs are, as far as possible, viewed from todays medical perspective.

  5. Improving the Performance and Resource Utilization of the CASPER FFT and Polyphase Filterbank (United States)

    Monroe, Ryan


    The effectiveness of Digital Signal Processing (DSP) solutions for radio-astronomy is limited by the efficiency of the implemented algorithms. Novel implementations of several popular DSP algorithms are presented. Their optimization strategies are discussed and their efficiency is compared to that of the standard Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) library solutions. Compared to CASPER, the PFB-FIR and FFT modules require 73% and 45% of the DSP48E1 resources, with performance dominated by ADC quantization noise for typical radio-astronomy inputs.

  11. Aldo Leopold's land health from a resilience point of view: self-renewal capacity of social-ecological systems. (United States)

    Berkes, Fikret; Doubleday, Nancy C; Cumming, Graeme S


    Health approaches to ecology have a strong basis in Aldo Leopold's thinking, and contemporary ecohealth in turn has a strong philosophical basis in Leopold. To commemorate the 125th anniversary of Leopold's birth (1887-1948), we revisit his ideas, specifically the notions of stewardship (land ethic), productive use of ecosystems (land), and ecosystem renewal. We focus on Leopold's perspective on the self-renewal capacity of the land, as understood in terms of integrity and land health, from the contemporary perspective of resilience theory and ecological theory more generally. Using a broad range of literature, we explore insights and implications of Leopold's work for today's human-environment relationships (integrated social-ecological systems), concerns for biodiversity, the development of agency with respect to stewardship, and key challenges of his time and of ours. Leopold's seminal concept of land health can be seen as a triangulation of productive use, self-renewal, and stewardship, and it can be reinterpreted through the resilience lens as the health of social-ecological systems. In contemporary language, this involves the maintenance of biodiversity and ecosystem services, and the ability to exercise agency both for conservation and for environmental justice.

  12. Luna B. Leopold--pioneer setting the stage for modern hydrology (United States)

    Hunt, Randall J.; Meine, Curt


    In 1986, during the first year of graduate school, the lead author was sampling the water from a pitcher pump in front of “The Shack,” the setting of the opening essays in Aldo Leopold's renowned book A Sand County Almanac. The sampling was part of my Master's work that included quarterly monitoring of water quality on the Leopold Memorial Reserve (LMR) near Baraboo, Wisconsin. The Shack was already a well-known landmark, and it was common to come upon visitors and hikers there. As such, I took no special note of the man who approached me as I was filling sample bottles and asked, as was typical, “What are you doing?”

  14. Integration and disease control: notes from the Prince Leopold Institute of Tropical Medicine Colloquium 2002. (United States)

    Mahendradhata, Yodi; Moerman, Filip


    The discussion on the desirability or not to integrate disease control activities with general health services is a longstanding one. The recent creations of global health initiatives for poverty-related disease control have refueled the debate. The Prince Leopold Institute of Tropical Medicine (ITM) convened a colloquium in Antwerp to clarify concepts involved in integrated disease control and contribute to the creation of a common scientific language and a better understanding of the issues at stake. We present an overview of highlights from the colloquium sessions. Some of the contributions reported here are presented in more detail elsewhere in this special issue.

  15. Atmospheric monitoring in the millimetre and submillimetre bands for cosmological observations: CASPER2 (United States)

    De Petris, M.; De Gregori, S.; Decina, B.; Lamagna, L.; Pardo, J. R.


    Cosmological observations from ground at millimetre and submillimetre wavelengths are affected by atmospheric absorption and consequent emission. The low- and high-frequency (sky-noise) fluctuations of atmospheric performance necessitate careful observational strategies and/or instrumental technical solutions. Measurements of atmospheric emission spectra are necessary for accurate calibration procedures as well as for site-testing statistics. CASPER2, an instrument designed to explore the 90-450 GHz (3-15 cm-1) spectral region, was developed and had its operation verified in the Alps. A Martin-Puplett interferometer (MPI) operates by comparing sky radiation, coming from a field of view (FOV) of 28 arcmin (full width at half-maximum) and collected by a 62-cm-diameter Pressman-Camichel telescope, with a reference source. The signals at the two output ports of the interferometer are detected by two bolometers cooled to 300 mK inside a wet cryostat. Three different but complementary interferometric techniques can be performed with CASPER2: amplitude modulation (AM), fast-scan (FS) and phase modulation (PM). An altazimuthal mount allows sky pointing, possibly co-aligned with the optical axis of the 2.6-m-diameter telescope of MITO (Millimetre and Infrared Testagrigia Observatory, Italy). The optimal time-scale to average acquired spectra is inferred by Allan variance analysis at five fiducial frequencies. We present the motivation for and design of the atmospheric spectrometer CASPER2. The procedure adopted to calibrate the instrument and the preliminary performance of it are described. Instrument capabilities were checked during the summer observational campaign at MITO in 2010 July by measuring atmospheric emission spectra with the three procedures.

  16. A Seven-Year Longitudinal Study of the Research Outcomes for the CASPER Physics Circus (United States)

    Carmona-Reyes, Jorge; Land-Zandstra, Anna; Stark, Gary; Tarman, Lisa; Menefee, Matt; Wang, Li; Cook, Mike; Schmoke, Jimmy; Matthews, Lorin; Hyde, Truell


    The CASPER Physics Circus was specifically designed to increase student interest in science, technology, engineering and mathematics (STEM) careers where the current generation of scientists and engineers is rapidly approaching retirement age. The Physics Circus followed Waco and LaVega ISD students starting in the sixth grade and ending in the twelfth grade with this cohort group attending the Physics Circus event on the Baylor University campus, interacting with CASPER graduate students and participating in hands-on instructional activities. The event was designed as an informal learning environment intervention and operated under the discovery, project and guided-inquiry base framework wrapped in a learner-center ideology. Participating students were allowed to experiment with hands-on manipulatives while interacting with physicists, science educators and graduate students in both STEM and science education fields. Professional Development was also a part of the Physics Circus for all science teachers within the cohort. This paper presents the results of a seven-year longitudinal study on the Physics Circus and presents future plans to expand the program's effectiveness and impact.

  17. Sequence-Based Mapping and Genome Editing Reveal Mutations in Stickleback Hps5 Cause Oculocutaneous Albinism and the casper Phenotype

    Directory of Open Access Journals (Sweden)

    James C. Hart


    Full Text Available Here, we present and characterize the spontaneous X-linked recessive mutation casper, which causes oculocutaneous albinism in threespine sticklebacks (Gasterosteus aculeatus. In humans, Hermansky-Pudlak syndrome results in pigmentation defects due to disrupted formation of the melanin-containing lysosomal-related organelle (LRO, the melanosome. casper mutants display not only reduced pigmentation of melanosomes in melanophores, but also reductions in the iridescent silver color from iridophores, while the yellow pigmentation from xanthophores appears unaffected. We mapped casper using high-throughput sequencing of genomic DNA from bulked casper mutants to a region of the stickleback X chromosome (chromosome 19 near the stickleback ortholog of Hermansky-Pudlak syndrome 5 (Hps5. casper mutants have an insertion of a single nucleotide in the sixth exon of Hps5, predicted to generate an early frameshift. Genome editing using CRISPR/Cas9 induced lesions in Hps5 and phenocopied the casper mutation. Injecting single or paired Hps5 guide RNAs revealed higher incidences of genomic deletions from paired guide RNAs compared to single gRNAs. Stickleback Hps5 provides a genetic system where a hemizygous locus in XY males and a diploid locus in XX females can be used to generate an easily scored visible phenotype, facilitating quantitative studies of different genome editing approaches. Lastly, we show the ability to better visualize patterns of fluorescent transgenic reporters in Hps5 mutant fish. Thus, Hps5 mutations present an opportunity to study pigmented LROs in the emerging stickleback model system, as well as a tool to aid in assaying genome editing and visualizing enhancer activity in transgenic fish.

    Typically, only a minority of applicants to health professional training are invited to interview. However, pre-interview measures of cognitive skills predict for national licensure scores (Gauer et al. in Med Educ Online 21 2016) and subsequently licensure scores predict for performance in practice (Tamblyn et al. in JAMA 288(23): 3019-3026, 2002; Tamblyn et al. in JAMA 298(9):993-1001, 2007). Assessment of personal and professional characteristics, with the same psychometric rigour of measures of cognitive abilities, are needed upstream in the selection to health profession training programs. To fill that need, Computer-based Assessment for Sampling Personal characteristics (CASPer)-an on-line, video-based screening test-was created. In this paper, we examine the correlation between CASPer and Canadian national licensure examination outcomes in 109 doctors who took CASPer at the time of selection to medical school. Specifically, CASPer scores were correlated against performance on cognitive and 'non-cognitive' subsections of both the Medical Council of Canada Qualifying Examination (MCCQE) Parts I (end of medical school) and Part II (18 months into specialty training). Unlike most national licensure exams, MCCQE has specific subcomponents examining personal/professional qualities, providing a unique opportunity for comparison. The results demonstrated moderate predictive validity of CASPer to national licensure outcomes of personal/professional characteristics three to six years after admission to medical school. These types of disattenuated correlations (r = 0.3-0.5) are not otherwise predicted by traditional screening measures. These data support the ability of a computer-based strategy to screen applicants in a feasible, reliable test, which has now demonstrated predictive validity, lending evidence of its validation for medical school applicant selection.

  20. When the King Becomes your Personal Enemy: W. T. Stead, King Leopold II, and the Congo Free State

    Directory of Open Access Journals (Sweden)

    Marysa Demoor


    mso-fareast-language:JA;} This paper will highlight an unknown but important episode in the life of the journalist W. T. Stead, which, intriguingly, remained unmentioned in Belgian, British, and colonial historiography. It concerns a face-to-face meeting between Stead and Leopold II, King of the Belgians, which certainly did not leave Stead the ‘friend of all Kings’, as the posthumous article published by the 'Daily Mirror' contended. Based on Stead’s own Character Sketches in the 'Review of Reviews', the paper will show how Stead’s perceptions of the scandalous government of the Congo Free State result to a large extent from his own meeting (probably towards the end of 1884 with King Leopold II, and the King’s refusal to cooperate with Britain in an improvised rescue of General Gordon in Sudan.

  1. «On the Origin of Species»: Didactic transposition to the curriculum and Portuguese science textbooks (1859-1959

    Directory of Open Access Journals (Sweden)

    Bento Cavadas


    Full Text Available This research aimed to contribute to the history of the teaching of Darwinism in the Portuguese curriculum from 1859 to 1959. To this end, it was analysed the didactic transposition of the book On the Origin of Species for the standards and textbooks of Natural Sciences of secondary education. This study showed that some standards did not address Darwinism (Standards of 1856, 1872, 1880, 1886, 1926 and 1929, while others only prescribed the study of some subjects of Darwinism (Standards of 1889 and 1905. The standards of 1895 were the ones that addressed more Darwinists ideas in the 19th century. In the 20th century, the overall approach to Darwinism was related to the study of transformist ideas (Standards of 1919 or evolution (Standards of 1936 and 1954. However, even when the respective standards did not make that prescription, the major part of textbooks addressed the mechanisms of Darwinian evolution: adaptation, variability, growth correlations, heredity, natural selection, vital competition, geographic isolation and sexual selection.

  2. Environmental policies, politics, and community risk perception: case study of community contamination in Casper, Wyoming. (United States)

    Tajik, Mansoureh; Gottlieb, Karen; Lowndes, Nita; Stewart, Gloria


    We identify and explain factors that affected a community's perception of risk due to extensive industrial contamination and people's distrust of government agencies regarding the environmental investigations. Intrinsic bounded case study methodology was used to conduct research about extensive environmental contaminations due to activities of an oil refinery in North Casper, Wyoming, and the citizens' response. Data were collected from multiple sources that included public testimonies, observations, public hearings and meetings minutes, newspaper articles, archived records obtained from federal and state environmental and health agencies, as well as industry records obtained through Freedom of Information Act (FOIA) requests. The overarching theme that emerged was lack of trust due to several critical events and factors such as no response or delay in response time to community concerns, lack of transparency, perceived cover up, vague and fragmented communication by government and state officials, perception of pro-industry stance, and perceived unfair treatment. People's perception of environmental risks and their willingness to accept official explanations and outcomes of environmental investigations are strongly affected by their direct experiences with government agencies and the evidence of influence the powerful industries exert over relevant investigations. The government cannot successfully address public and community concerns about environmental health impacts of contaminations and in turn the public perception of risk unless it adopts and implements policies, procedures, and protocols that are clear, timely, transparent, and free from industry influence.

  3. Erich Fromm's productivity: creativity as exemplified by Joyce's blooming of Leopold and Molly. (United States)

    Harrell, Valentina


    According to Erich Fromm, the productive character expresses what he called the life force in ways that are, by nature, artistic in quality. His valuing of the vital and the artistic, fueled by this life force in our potential to be human, serves as the cornerstone of his model of psychoanalysis. Gilbert Rose, author of Necessary Illusion: Art as "Witness", also has identified the parallel between analytic and artistic processes, building on the assumption that the therapeutic alliance and the aesthetic alliance are one and the same. In elaborating this assumption and extending the parallel between Rose and Fromm, I draw the conclusion that the qualities of relationships have an impact on one's ability to express oneself creatively, to live an artistic life--that is, to live productively. Psychoanalysis is, in practice, a process that is artistic, creative, and re-creative in nature. To the degree that authentic expression of emotionally charged implicit knowledge of the ineffable (the emotional life that resides deep in the bodymind) results in transformation and healing, the process is artistic in nature. This process is exemplified by examining the life and literary creations of James Joyce, especially Joyce's characters of Molly and Leopold Bloom in Ulysses.

  4. Leopold: the "bleeder prince" and public knowledge about hemophilia in Victorian Britain. (United States)

    Rushton, Alan R


    Hemophilia is a rare bleeding disorder inherited by males born of unaffected female carriers of the trait. British physicians became knowledgeable about this hereditary disease early in the nineteenth century as they investigated families transmitting the character through several generations. Prince Leopold (b. 1853), the fourth son of Queen Victoria, experienced recurrent bleeding episodes and was diagnosed with hemophilia during childhood. His hemorrhagic attacks were first described in the medical journals during 1868, and subsequently in the London and provincial newspapers. The royal family carefully managed news about health matters, and many newspapers reported widespread public sympathy for the travails of the queen and her children. But the republican press argued that the disaffected working classes resented the hyperbole connecting the health of royal individuals with the political future of the entire nation. Public discussion of hemophilia transformed it from a rare medical phenomenon to a matter of national news. Practicing physicians, the royal family, and the general public all came to understand the clinical features and the hereditary nature of the problem. Members of the royal family subsequently utilized this information to guide the marriages of their own children to prevent the spread of this dreaded bleeding disorder.

  5. Assessment of the influence of anthropogenic factors on elements of the ecological network in Vojvodina (Serbia using the Leopold matrix

    Directory of Open Access Journals (Sweden)

    Kicošev Vesna


    Full Text Available Salt steppes and marshes represent the most valuable ecosystems in the world, providing numerous ecosystem services that are extremely vulnerable to anthropogenic influences. These types of habitat in the territory of Serbia are most dominant in Banat and a significant portion of them is under protection or in the process of becoming protected. The section surrounding the protected areas of Slano Kopovo Special Nature Reserve, Rusanda Nature Park and Okanj Bara Special Nature Reserve with the non-building area of Novi Bečej, Kumane, Melenci, Elemir and Taraš cadastral municipalities, has been chosen for the analysis. The aim of this paper was to assess the influence of specific anthropogenic factors on the elements of an ecological network using the analytical method that can generate the required results in a manner suitable for presentation to various stakeholders. To achieve this aim, the Leopold matrix model, used for assessing anthropogenic influence on the environment, has been chosen. The specificity of this issue of protecting and preserving elements of an ecological network resulted in the need to isolate and evaluate the factors affecting the preservation of habitats and functionality of ecosystems, unlike the concept of Leopold matrix, which treats all factors as equally important in the process of evaluation. Evaluation results indicate significant effects of historical, perennial manner of using the area and other resources in the non-building area.

  6. Chaos Theory and James Joyce's "ulysses": Leopold Bloom as a Human COMPLEX@SYSTEM^ (United States)

    Mackey, Peter Francis


    These four ideas apply as much to our lives as to the life of Leopold Bloom: (1) A trivial decision can wholly change a life. (2) A chance encounter can dramatically alter life's course. (3) A contingent nexus exists between consciousness and environment. (4) A structure of meaning helps us interpret life's chaos. These ideas also relate to a contemporary science called by some "chaos theory." The connection between Ulysses and chaos theory enhances our understanding of Bloom's day; it also suggests that this novel may be about the real process of life itself. The first chapter explains how Joyce's own essays and comments to friends compel attention to the links between Ulysses and chaos theory. His scientific contemporaries anticipated chaos theory, and their ideas seem to have rubbed off on him. We see this in his sense of trivial things and chance, his modernistic organizational impulses, and the contingent nature of Bloom's experience. The second chapter studies what chaos theory and Joyce's ideas tell us about "Ithaca," the episode which particularly implicates our processes of interpreting this text as well as life itself as we face their chaos. The third chapter examines Bloom's close feel for the aboriginal world, a contingency that clarifies his vulnerability to trivial changes. The fourth chapter studies how Bloom's stream of consciousness unfolds--from his chance encounters with trivial things. Beneath this stream's seeming chaos, Bloom's distinct personality endures, similar to how Joyce's schemas give Ulysses an imbedded, underlying order. The fifth chapter examines how trivial perturbations, such as Lyons' misunderstanding about "Throwaway," produce small crises for Bloom, exacerbating his seeming impotence before his lonely "fate.". The final chapter analyzes Bloom's views that fate and chance dictate his life. His views provide an opportunity to explore the implications chaos theory has for our understanding of free will and determinism. Ultimately

  10. O litoral do Nordeste do Brasil como objeto científico darwinista: as prospecções de John Casper Branner, 1899-1911

    Directory of Open Access Journals (Sweden)

    Almir Leal de Oliveira


    Full Text Available John Casper Branner, geólogo norte-americano, desenvolveu uma longa história de investigação no Brasil. Analisa-se, aqui, como ele tratou a geologia do litoral do Nordeste na Branner-Agassiz Expedition (1899 e na Stanford Expedition (1911. As expedições indicam como a geomorfologia das bacias sedimentares, dos recifes de arenito e dos recifes de corais foi caracterizada sob uma perspectiva evolutiva darwinista. Branner integrou o modelo de pesquisa de campo da história natural com as práticas da biologia moderna e da geologia dinâmica, e interpretou a evolução da formação geológica a partir dos fatores físico-químicos. Os estudos zoológicos identificaram o lugar da variação e das adaptações evolutivas das espécies marinhas isoladas como fator auxiliar da seleção natural.

  11. CASPER: Embedding Power Estimation and Hardware-Controlled Power Management in a Cycle-Accurate Micro-Architecture Simulation Platform for Many-Core Multi-Threading Heterogeneous Processors

    Directory of Open Access Journals (Sweden)

    Arun Ravindran


    Full Text Available Despite the promising performance improvement observed in emerging many-core architectures in high performance processors, high power consumption prohibitively affects their use and marketability in the low-energy sectors, such as embedded processors, network processors and application specific instruction processors (ASIPs. While most chip architects design power-efficient processors by finding an optimal power-performance balance in their design, some use sophisticated on-chip autonomous power management units, which dynamically reduce the voltage or frequencies of idle cores and hence extend battery life and reduce operating costs. For large scale designs of many-core processors, a holistic approach integrating both these techniques at different levels of abstraction can potentially achieve maximal power savings. In this paper we present CASPER, a robust instruction trace driven cycle-accurate many-core multi-threading micro-architecture simulation platform where we have incorporated power estimation models of a wide variety of tunable many-core micro-architectural design parameters, thus enabling processor architects to explore a sufficiently large design space and achieve power-efficient designs. Additionally CASPER is designed to accommodate cycle-accurate models of hardware controlled power management units, enabling architects to experiment with and evaluate different autonomous power-saving mechanisms to study the run-time power-performance trade-offs in embedded many-core processors. We have implemented two such techniques in CASPER–Chipwide Dynamic Voltage and Frequency Scaling, and Performance Aware Core-Specific Frequency Scaling, which show average power savings of 35.9% and 26.2% on a baseline 4-core SPARC based architecture respectively. This power saving data accounts for the power consumption of the power management units themselves. The CASPER simulation platform also provides users with complete support of SPARCV9

    Depression accounts for the greatest disease burden of all mental health disorders, contributes heavily to healthcare costs, and by 2020 is set to become the second largest cause of global disability. Although 10% to 16% of people aged 65 years and over are likely to experience depressive symptoms, the condition is under-diagnosed and often inadequately treated in primary care. Later-life depression is associated with chronic illness and disability, cognitive impairment and social isolation. With a progressively ageing population it becomes increasingly important to refine strategies to identity and manage depression in older people. Currently, management may be limited to the prescription of antidepressants where there may be poor concordance; older people may lack awareness of psychosocial interventions and general practitioners may neglect to offer this treatment option. CASPER Plus is a multi-centre, randomised controlled trial of a collaborative care intervention for individuals aged 65 years and over experiencing moderate to severe depression. Selected practices in the North of England identify potentially eligible patients and invite them to participate in the study. A diagnostic interview is carried out and participants with major depressive disorder are randomised to either collaborative care or usual care. The recruitment target is 450 participants. The intervention, behavioural activation and medication management in a collaborative care framework, has been adapted to meet the complex needs of older people. It is delivered over eight to 10 weekly sessions by a case manager liaising with general practitioners. The trial aims to evaluate the clinical and cost effectiveness of collaborative care in addition to usual GP care versus usual GP care alone. The primary clinical outcome, depression severity, will be measured with the Patient Health Questionnaire-9 (PHQ-9) at baseline, 4, 12 and 18 months. Cost effectiveness analysis will assess health

    Depression in older adults is common and is associated with poor quality of life, increased morbidity and early mortality, and increased health and social care use. Collaborative care, a low-intensity intervention for depression that is shown to be effective in working-age adults, has not yet been evaluated in older people with depression who are managed in UK primary care. The CollAborative care for Screen-Positive EldeRs (CASPER) plus trial fills the evidence gap identified by the most recent guidelines on depression management. To establish the clinical effectiveness and cost-effectiveness of collaborative care for older adults with major depressive disorder in primary care. A pragmatic, multicentred, two-arm, parallel, individually randomised controlled trial with embedded qualitative study. Participants were automatically randomised by computer, by the York Trials Unit Randomisation Service, on a 1 : 1 basis using simple unstratified randomisation after informed consent and baseline measures were collected. Blinding was not possible. Sixty-nine general practices in the north of England. A total of 485 participants aged ≥ 65 years with major depressive disorder. A low-intensity intervention of collaborative care, including behavioural activation, delivered by a case manager for an average of six sessions over 7-8 weeks, alongside usual general practitioner (GP) care. The control arm received only usual GP care. The primary outcome measure was Patient Health Questionnaire-9 items score at 4 months post randomisation. Secondary outcome measures included depression severity and caseness at 12 and 18 months, the EuroQol-5 Dimensions, Short Form questionnaire-12 items, Patient Health Questionnaire-15 items, Generalised Anxiety Disorder-7 items, Connor-Davidson Resilience Scale-2 items, a medication questionnaire, objective data and adverse events.

    Kavakli, K; Yang, R; Rusen, L; Beckmann, H; Tseneklidou-Stoeter, D; Maas Enriquez, M


    BAY 81-8973 is a new full-length human recombinant factor VIII product manufactured with technologies to improve consistency in glycosylation and expression to optimize clinical performance. To demonstrate superiority of prophylaxis vs. on demand therapy with BAY 81-8973 in patients with severe hemophilia A. In this multinational,randomized, open-label crossover study (LEOPOLD II; identifier: NCT01233258), males aged 12–65 years with severe hemophilia A were randomized to twice-weekly prophylaxis (20-30 IU kg(-1)), 3-times-weekly prophylaxis (30-40 IU kg(-1)), or on-demand treatment with BAY 81-8973. Potency labeling for BAY 81-8973 was based on the chromogenic substrate assay or adjusted to the one-stage assay. Primary efficacy endpoint was annualized number of all bleeds (ABR). Adverse events (AEs)and immunogenicity were also assessed. Eighty patients (on demand, n = 21; twice-weekly prophylaxis, n = 28; 3-times-weekly prophylaxis, n = 31) were treated and analyzed. Mean ± SD ABR was significantly lower with prophylaxis (twice-weekly, 5.7 ± 7.2; 3-times-weekly, 4.3 ± 6.5; combined, 4.9 ± 6.8) vs. on-demand treatment (57.7 ± 24.6; P demand treatment (60.0). Median ABR was higher with twice-weekly vs. 3-times-weekly prophylaxis during the first 6-month treatment period (4.1 vs. 2.0) but was comparable in the second 6-month period (1.1 vs. 2.0). Few patients reported treatment-related AEs (4%); no treatment-related serious AEs or inhibitors were reported. Twice weekly or 3-times-weekly prophylaxis with BAY 81-8973 reduced median ABR by 97% compared with on-demand therapy, confirming the superiority of prophylaxis. Treatment with BAY 81-8973 was well tolerated.

  19. Baseline Vascular Cognitive Impairment Predicts the Course of Apathetic Symptoms After Stroke: The CASPER Study. (United States)

    Douven, Elles; Köhler, Sebastian; Schievink, Syenna H J; van Oostenbrugge, Robert J; Staals, Julie; Verhey, Frans R J; Aalten, Pauline


    To examine the influence of vascular cognitive impairment (VCI) on the course of poststroke depression (PSD) and poststroke apathy (PSA). Included were 250 stroke patients who underwent neuropsychological and neuropsychiatric assessment 3 months after stroke (baseline) and at a 6- and 12-month follow-up after baseline. Linear mixed models tested the influence of VCI in at least one cognitive domain (any VCI) or multidomain VCI (VCI in multiple cognitive domains) at baseline and domain-specific VCI at baseline on levels of depression and apathy over time, with random effects for intercept and slope. Almost half of the patients showed any VCI at baseline, and any VCI was associated with increasing apathy levels from baseline to the 12-month follow-up. Patients with multidomain VCI had higher apathy scores at the 6- and 12-month follow-up compared with patients with VCI in a single cognitive domain. Domain-specific analyses showed that impaired executive function and slowed information processing speed went together with increasing apathy levels from baseline to 6- and 12-month follow-up. None of the cognitive variables predicted the course of depressive symptoms. Baseline VCI is associated with increasing apathy levels from baseline to the chronic stroke phase, whereas no association was found between baseline VCI and the course of depressive symptoms. Health professionals should be aware that apathy might be absent early after stroke but may evolve over time in patients with VCI. Copyright © 2017 The Authors. Published by Elsevier Inc.

    The decline of amphibian species has emerged as a major global conservation issue in the last decade. Last year, the Department of the Interior (DOI) initiated a major national initiative to detect trends in amphibian populations and research the causes of declines. The program, conducted principally by the U.S. Geological Survey (USGS), emphasizes lands managed by DOI, but collaboration with the Forest Service is encouraged to increase the scope of inference about population trends. Although amphibians are not usually the first group of animals that comes to mind when one thinks of wilderness, conservation of amphibian populations is clearly a wilderness issue.

  11. Environmental Survey preliminary report, Naval Petroleum and Oil Shale Reserves in Colorado, Utah, and Wyoming, Casper, Wyoming

    Energy Technology Data Exchange (ETDEWEB)


    This report presents the preliminary environmental findings from the first phase of the Environmental Survey of the United States Department of Energy (DOE) Naval Petroleum and Oil Shale Reserves in Colorado, Utah, and Wyoming (NPOSR-CUW) conducted June 6 through 17, 1988. NPOSR consists of the Naval Petroleum Reserve No. 3 (NPR-3) in Wyoming, the Naval Oil Shale Reserves No. 1 and 3 (NOSR-1 and NOSR-3) in Colorado and the Naval Oil Shale Reserve No. 2 (NOSR-2) in Utah. NOSR-2 was not included in the Survey because it had not been actively exploited at the time of the on-site Survey. The Survey is being conducted by an interdisciplinary team of environmental specialists, lead and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. Individual team specialists are outside experts being supplied by a private contractor. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with NPOSR. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. This phase of the Survey involves the review of existing site environmental data, observations of the operations carried on at NPOSR and interviews with site personnel. The Survey team has developed a Sampling and Analysis Plan to assist in further assessing specific environmental problems identified at NOSR-3 during the on-site Survey. There were no findings associated with either NPR-3 or NOSR-1 that required Survey-related sampling and Analysis. The Sampling and Analysis Plan will be executed by Idaho National Engineering Laboratory. When completed, the results will be incorporated into the Environmental Survey Summary report. The Summary Report will reflect the final determinations of the NPOSR-CUW Survey and the other DOE site-specific Surveys. 110 refs., 38 figs., 24 tabs.

  20. Life adversity in depressed and non-depressed older adults: A cross-sectional comparison of the brief LTE-Q questionnaire and life events and difficulties interview as part of the CASPER study. (United States)

    Donoghue, Hjördis M; Traviss-Turner, Gemma D; House, Allan O; Lewis, Helen; Gilbody, Simon


    There is a paucity of research on the nature of life adversity in depressed and non-depressed older adults. Early life events work used in-depth interviews; however, larger epidemiological trials investigate life adversity using brief questionnaires. This study investigates the type of life adversity experienced in later life and its association with depression and compares adversity captured using a brief (LTE-Q) and in-depth (LEDS) measure. 960 participants over 65 years were recruited in UK primary care to complete the PHQ-9 and LTE-Q. A sub-sample (n=19) completed the LEDS and a question exploring the subjective experience of the LTE-Q and LEDS. Important life adversity was reported on the LTE-Q in 48% of the sample. In the LTE-Q sample the prevalence of depression (PHQ-9≥10) was 12%. Exposure to recent adversity was associated with doubling of the odds of depression. The LTE-Q only captured a proportion of adversity measured by the LEDS (42% vs 84%). Both measures showed health, bereavement and relationship events were most common. The cross-sectional design limits the extent to which inferences can be drawn around the direction of causality between adversity and depression. Recall in older adults is questionable. UK older adults face adversity in areas of health, bereavement and relationships which are associated with depression. This has clinical relevance for psychological interventions for older adults to consider social context and social support. It helps identify the strengths and weaknesses of a brief adversity measure in large scale research. Further research is needed to explore the mechanisms of onset and direction of causality.

  2. Léopold Senghor e Aimé Césaire letti e interpretati da Giulio Stocchi - Leopold Senghor and Aimé Césaire read and interpreted by Giulio Stocchi

    Directory of Open Access Journals (Sweden)

    Giulio Stocchi


    Full Text Available This article makes an analysis of fantasy travelling. The poet moves fast between situations and emotions which arise within a continuous and intense familiarity with alterity. Stocchi tells us poetically about two young poets, Aimé Césaire (future sensitive politician and mayor of Fort-de France, capital city of Martinique who goes back to Martinique on a steamer and Léopold Senghor (future president of Senegal and member of the Academie Française who travels back to the fabulous Africa of his childhood on the wings of fantasy. Poetry and more generally art becomes thus the model that men have built for themselves in order to have access to their imagination: The travel of poetry takes place without passport and checkpoints, without borders and States, beyond countries and continents in an universe of changing and heart-rending emotions.

    Objective An 8.3 magnitude earthquake followed by tsunami waves devastated American Samoa on September 29, 2009, resulting in widespread loss of property and public services. An initial and a follow-up Community Needs Assessment for Public Health Emergency Response (CASPER) objectively quantified disaster-affected population needs. Methods Using a 2-stage cluster sampling method of CASPER, a household questionnaire eliciting information about medical and basic needs, illnesses, and injuries was administered. To assess response efforts, percent changes in basic and medical needs, illnesses, and injuries between the initial and follow-up CASPER were calculated. Results During the initial CASPER (N=212 households), 47.6% and 51.6% of households reported needing a tarpaulin and having no electricity, respectively. The self-reported greatest needs were water (27.8%) and financial help with cleanup (25.5%). The follow-up CASPER (N=207 households) identified increased vector problems compared to pre-tsunami, and food (26%) was identified as the self-reported greatest need. As compared to the initial CASPER, the follow-up CASPER observed decreases in electricity (−78.3%), drinking water (−44.4%), and clothing (−26.6%). Conclusion This study highlights the use of CASPER during the response and recovery phases following a disaster. The initial CASPER identified basic needs immediately after the earthquake, whereas the follow-up CASPER assessed effectiveness of relief efforts and identified ongoing community needs.

  16. Marine Atmospheric Surface Layer and Its Application to Electromagnetic Wave Propagation (United States)

    Wang, Q.


    An important application of the atmospheric surface layer research is to characterize the near surface vertical gradients in temperature and humidity in order to predict radar and radio communication conditions in the environment. In this presentation, we will give an overview of a new research initiative funded under the Office of Naval Research (ONR) Multi-University Research Initiative (MURI): the Coupled Air-Sea Processes and EM Ducting Research (CASPER). The objective is to fully characterize the marine atmospheric boundary layer (MABL) as an electromagnetic (EM) propagation environment with the emphasis of spatial and temporal heterogeneities and surface wave/swell effects, both of which contravene the underlying assumptions of Monin-Obukhov Similarity Theory (MOST) used in coupled environmental forecast models. Furthermore, coastal variability in the inversion atop the MABL presents a challenge to forecast models and also causes practical issues in EM prediction models. These issues are the target of investigation of CASPER. CASPER measurement component includes two major field campaigns: CASPER-East (2015 Duck, NC) and CASPER-West (2018 southern California). This presentation will show the extensive measurements to be made during the CASPER -East field campaign with the focus on the marine atmospheric surface layer measurements with two research vessels, two research aircraft, surface flux buoy, wave gliders, ocean gliders, tethered balloons, and rawinsondes. Unlike previous research on the marine surface layer with the focus on surface fluxes and surface flux parameterization, CASPER field campaigns also emphasize of the surface layer profiles and the validation of the surface layer flux-profile relationship originally derived over land surfaces. Results from CASPER pilot experiment and preliminary results from CASPER-East field campaign will be discussed.

  19. Ecological sustainability as the fourth landmark in the development of conservation ethics. (United States)

    White, Peter S; Tuttle, Julie P


    Aldo Leopold, in "The Land Ethic," made 2 important contributions to conservation ethics: he emphasized the community and ecosystem levels of organization and he explicitly included people as members of the biotic community. Leopold's writings remain eloquent, inspirational, and influential, but the ideas he describes are inherently complex, and ecological science has continued to evolve since "The Land Ethic" was published in 1949. We used 4 sets of quotations from Leopold's essays to develop our commentary on the meaning of and challenges in interpreting his work and to explore the ongoing development of conservation ethics: the "A-B cleavage" (Leopold's description of the contrast between utilitarian value versus a broader definition of value in nature), "land health" and the rightness of human action, the right of all species to continued existence in natural populations "at least in spots," and humans as "plain member[s] and citizen[s]" of the "land-community." We define the broader function of land and land health in "The Land Ethic" as including completeness, dynamic stability, and self-renewal in a way that incorporates the needs of humans and all other species. We argue that the consequences of implementing Leopold's land ethic include multiple conservation goals nested within an overall systems approach and that conservation science must clarify the implications of Leopold's ethic by quantitatively investigating and defining large-scale, system-level ecological sustainability. At this scale, land use will encompass areas ranging from large expanses of wilderness to areas dominated by humans. © 2013 Society for Conservation Biology.

  20. A Comparison between Local and Global Spaceborne Chlorophyll Indices in the St. Lawrence Estuary

    Directory of Open Access Journals (Sweden)

    Martin A. Montes-Hugo


    Full Text Available Spaceborne chlorophyll indices based on red fluorescence (wavelength = 680 nm and water leaving radiance (Lw in the visible spectrum (i.e., 400–700 nm were evaluated in the St Lawrence Estuary (SLE during September of 2011. Relationships between chlorophyll concentration (chl and fluorescence were constructed based on fluorescence line height (FLH measurements derived from a compact laser-based spectrofluorometer developed by ENEA (CASPER and using spectral bands corresponding to the satellite sensor MERIS (MEdium Resolution Imaging Spectrometer. Chlorophyll concentration as estimated from CASPER (chlCASPER was relatively high NE of the MTZ (upper Estuary, and nearby areas influenced by fronts or freshwater plumes derived from secondary rivers (lower estuary. These findings agree with historical shipboard measurements. In general, global chl products calculated from Lw had large biases (up to 27-fold overestimation and 50-fold underestimation with respect to chlCASPER values. This was attributed to the smaller interference of detritus (mineral + organic non-living particulates and chromophoric dissolved organic matter on chlCASPER estimates. We encourage the use of spectrofluorometry for developing and validating remote sensing models of chl in SLE waters and other coastal environments characterized by relatively low to moderate (<10 g·m−3 concentrations of detritus.

  2. Leveraging Parallel Data Processing Frameworks with Verified Lifting

    Directory of Open Access Journals (Sweden)

    Maaz Bin Safeer Ahmad


    Full Text Available Many parallel data frameworks have been proposed in recent years that let sequential programs access parallel processing. To capitalize on the benefits of such frameworks, existing code must often be rewritten to the domain-specific languages that each framework supports. This rewriting–tedious and error-prone–also requires developers to choose the framework that best optimizes performance given a specific workload. This paper describes Casper, a novel compiler that automatically retargets sequential Java code for execution on Hadoop, a parallel data processing framework that implements the MapReduce paradigm. Given a sequential code fragment, Casper uses verified lifting to infer a high-level summary expressed in our program specification language that is then compiled for execution on Hadoop. We demonstrate that Casper automatically translates Java benchmarks into Hadoop. The translated results execute on average 3.3x faster than the sequential implementations and scale better, as well, to larger datasets.

  3. Pilot evaluation of the Computer-Based Assessment for Sampling Personal Characteristics test. (United States)

    Shipper, Edward S; Mazer, Laura M; Merrell, Sylvia Bereknyei; Lin, Dana T; Lau, James N; Melcher, Marc L


    High attrition rates hint at deficiencies in the resident selection process. The evaluation of personal characteristics representative of success is difficult. Here, we evaluate a novel tool for assessing personal characteristics. To evaluate feasibility, we used an anonymous voluntary survey questionnaire offered to study participants before and after contact with the CASPer test. To evaluate the CASPer test as a predictor of success, we compared CASPer test assessments of personal characteristics versus traditional faculty assessment of personal characteristics with applicant rank list position. All applicants (n = 77) attending an in-person interview for general surgery residency, and all faculty interviewers (n = 34) who reviewed these applications were invited to participate. Among applicants, 84.4% of respondents (65 of 77) reported that a requirement to complete the CASPer test would have no bearing or would make them more likely to apply to the program (mean = 3.30, standard deviation = 0.96). Among the faculty, 62.5% respondents (10 of 16) reported that the same condition would have no bearing or would make applicants more likely to apply to the program (mean = 3.19, standard deviation = 1.33). The Spearman's rank-order correlation coefficients for the relationships between traditional faculty assessment of personal characteristics and applicant rank list position, and novel CASPer assessment of personal characteristics and applicant rank list position, were -0.45 (P = 0.033) and -0.41 (P = 0.055), respectively. The CASPer test may be feasibly implemented as component of the resident selection process, with the potential to predict applicant rank list position and improve the general surgery resident selection process.

  4. Developments of FPGA-based digital back-ends for low frequency antenna arrays at Medicina radio telescopes (United States)

    Naldi, G.; Bartolini, M.; Mattana, A.; Pupillo, G.; Hickish, J.; Foster, G.; Bianchi, G.; Lingua, A.; Monari, J.; Montebugnoli, S.; Perini, F.; Rusticelli, S.; Schiaffino, M.; Virone, G.; Zarb Adami, K.

    In radio astronomy Field Programmable Gate Array (FPGA) technology is largely used for the implementation of digital signal processing techniques applied to antenna arrays. This is mainly due to the good trade-off among computing resources, power consumption and cost offered by FPGA chip compared to other technologies like ASIC, GPU and CPU. In the last years several digital backend systems based on such devices have been developed at the Medicina radio astronomical station (INAF-IRA, Bologna, Italy). Instruments like FX correlator, direct imager, beamformer, multi-beam system have been successfully designed and realized on CASPER (Collaboration for Astronomy Signal Processing and Electronics Research, processing boards. In this paper we present the gained experience in this kind of applications.

  5. Parallel, Asynchronous Executive (PAX): System concepts, facilities, and architecture (United States)

    Jones, W. H.


    The Parallel, Asynchronous Executive (PAX) is a software operating system simulation that allows many computers to work on a single problem at the same time. PAX is currently implemented on a UNIVAC 1100/42 computer system. Independent UNIVAC runstreams are used to simulate independent computers. Data are shared among independent UNIVAC runstreams through shared mass-storage files. PAX has achieved the following: (1) applied several computing processes simultaneously to a single, logically unified problem; (2) resolved most parallel processor conflicts by careful work assignment; (3) resolved by means of worker requests to PAX all conflicts not resolved by work assignment; (4) provided fault isolation and recovery mechanisms to meet the problems of an actual parallel, asynchronous processing machine. Additionally, one real-life problem has been constructed for the PAX environment. This is CASPER, a collection of aerodynamic and structural dynamic problem simulation routines. CASPER is not discussed in this report except to provide examples of parallel-processing techniques.

    Full Text Available This paper consists of a short version of the derivation of the intuitionistic quantum logic L_QM (which was originally introduced by Caspers, Heunen, Landsman and Spitters. The elaboration consists of extending this logic to a classical logic CL_QM. Some first steps are then taken towards setting up a probabilistic framework based on CL_QM in terms of Rényi's conditional probability spaces. Comparisons are then made with the traditional framework for quantum probabilities.

  12. A Forest Fire Sensor Web Concept with UAVSAR (United States)

    Lou, Y.; Chien, S.; Clark, D.; Doubleday, J.; Muellerschoen, R.; Zheng, Y.


    We developed a forest fire sensor web concept with a UAVSAR-based smart sensor and onboard automated response capability that will allow us to monitor fire progression based on coarse initial information provided by an external source. This autonomous disturbance detection and monitoring system combines the unique capabilities of imaging radar with high throughput onboard processing technology and onboard automated response capability based on specific science algorithms. In this forest fire sensor web scenario, a fire is initially located by MODIS/RapidFire or a ground-based fire observer. This information is transmitted to the UAVSAR onboard automated response system (CASPER). CASPER generates a flight plan to cover the alerted fire area and executes the flight plan. The onboard processor generates the fuel load map from raw radar data, used with wind and elevation information, predicts the likely fire progression. CASPER then autonomously alters the flight plan to track the fire progression, providing this information to the fire fighting team on the ground. We can also relay the precise fire location to other remote sensing assets with autonomous response capability such as Earth Observation-1 (EO-1)'s hyper-spectral imager to acquire the fire data.

    Full Text Available Upon leaving Tuscany to become Holy Roman Emperor, Leopold II left some notes (1790 that prove very interesting to today’s economist. They show how a holistic approach to the socio-economic characteristics of a region should always be considered, starting from a people’s spirit, or ‘representative character’. This article summarises Leopold’s notes and draws some implication for the modern study of urban and regional economics.  JEL: R11, B11, B15

    In the context of modern scientific and technological developments in biomedicine and health care, and the potential consequences of their application on humans and the environment, Potter's global bioethics concept resurfaces. By actualizing Potter's original thoughts on individual bioethical issues, the universality of two of his books, which today represent the backbone of the world bioethical literature, "Bioethics--Bridge to the Future" and "Global Bioethics: Building on the Leopold Legacy", is emphasized. Potter's global bioethics today can legitimately be viewed as a bridge between clinical personalized ethics on the one hand and ethics of public health on the other.

  16. Looking at Animals without Seeing Them: Havelock Ellis in the “Circe” Episode of Ulysses

    Directory of Open Access Journals (Sweden)

    Ronan Crowley


    Full Text Available Taking wing from Joyce’s reading of Havelock Ellis’s Studies in the Psychology of Sex, in which the Irish writer found an account of cross-species sexual contact, this essay explores Leopold Bloom’s animal metamorphosis in the “Circe” episode of Ulysses. It argues that this encounter with the nonhuman animal is subordinated to the cause of working through barriers of human difference. In the process, the animal that enables this reconciliation disappears. Unable to represent animal interiority, “Circe” settles for merely probing their interiors.

  8. History repeating itself with a difference: Telemachus’ and Milly Bloom’s coming-of-age arcs

    Directory of Open Access Journals (Sweden)

    Kelly Lima


    Full Text Available Among the many references and multiple parallels between James Joyce's Ulysses and Homer's Odyssey, the mirroring between Leopold Bloom and Odysseus, Molly Bloom and Penelope, Stephen Dedalus and Telemachus stands out. However, although Stephen is the "spiritual son" of Leopold, the Blooms have a more literal heir: their daughter Milly Bloom. Just like Telemachus, Milly is the mirror of the family, has a clear preference for her father and clashes with her mother as she get older. Both are only children who carry the expectation of their parents, and when they hurriedly leave their homes for a world that will give them more experience, they continue to influence an unbalanced home. Therefore, in this paper, my aim is to point out how Telemachus coming-of-age, one of the three narrative strands of the Odyssey, relates to the references made throughout Ulysses to Milly's maturity, indicating how these two movements affect the actions of other characters and the development of the plot.

  9. Sensory memory of structure-from-motion is shape-specific. (United States)

    Pastukhov, Alexander; Füllekrug, Jana; Braun, Jochen


    Perceptual priming can stabilize the phenomenal appearance of multistable visual displays (Leopold, Wilke, Maier, & Logothetis, Nature Neuroscience, 5, 605-609, 2002). Prior exposure to such displays induces a sensory memory of their appearance, which persists over long intervals and intervening stimulation, and which facilitates renewed perception of the same appearance. Here, we investigated perceptual priming for the apparent rotation in depth of ambiguous structure-from-motion (SFM) displays. Specifically, we generated SFM objects with different three-dimensional shapes and presented them in random order and with intervening blank periods. To assess perceptual priming, we established the probability that a perceived direction of rotation would persist between successive objects. In general, persistence was greatest between identical objects, intermediate between similar objects, and negligible between dissimilar objects. These results demonstrate unequivocally that sensory memory for apparent rotation is specific to three-dimensional shape, contrary to previous reports (e.g., Maier, Wilke, Logothetis, & Leopold, Current Biology, 13, 1076-1085, 2003). Because persistence did not depend on presentation order for any pair of objects, it provides a commutative measure for the similarity of object shapes. However, it is not clear exactly which features or aspects of object shape determine similarity. At least, we did not find simple, low-level features (such as volume overlap, heterogeneity, or rotational symmetry) that could have accounted for all observations. Accordingly, it seems that sensory memory of SFM (which underlies priming of ambiguous rotation) engages higher-level representations of object surface and shape.

  10. Holocaust or Benevolent Paternalism? Intergenerational Comparisons on Collective Memories and Emotions about Belgium's Colonial Past

    Directory of Open Access Journals (Sweden)

    Olivier Klein


    Full Text Available After publication of Adam Hochschild's King Leopold's Ghost in 1998, asserting that King Leopold II had been responsible for a "holocaust" in the Congo and the heated public debate this provoked, we set out to study Belgian people's reactions to these accusations. In two studies we compared collective memories of and emotions associated with Belgium's colonial action in the Congo in different generations. Results show higher levels of collective guilt and support for reparative actions among young adults than among older generations. This difference can be explained either by referring to the different ideological backgrounds in which different generations were socialized, as evidenced by stark differences in collective memories of colonialism, or by referring to the influence of national identification. Indeed, people could adapt their representations of colonialism in order to avoid experiencing a social identity threat. However, evidence for the identity-protecting functions of collective memories and collective emotions was only found in the older generations: young people held negative representations of colonialism independently of their level of national identification. We refer to the normative dimension of collective guilt to interpret these results.

  11. Radon and aerosol release from open-pit uranium mining

    International Nuclear Information System (INIS)

    Thomas, V.W.; Nielson, K.K.; Mauch, M.L.


    The quantity of 222 Rn (hereafter called radon) released per unit of uranium produced from open pit mining has been determined. A secondary objective was to determine the nature and quantity of airborne particles resulting from mine operations. To accomplish these objectives, a comprehensive study of the release rates of radon and aerosol material to the atmosphere was made over a one-year period from April 1979 to May 1980 at the Morton Ranch Mine which was operated by United Nuclear Corporation (UNC) in partnership with Tennessee Valley Authority (TVA). The mine is now operated for TVA by Silver King Mines. Morton Ranch Mine was one of five open pit uranium mines studied in central Wyoming. Corroborative measurements were made of radon flux and 226 Ra (hereafter called radium) concentrations of various surfaces at three of the other mines in October 1980 and again at these three mines plus a fourth in April of 1981. Three of these mines are located in the Powder River Basin, about 80 kilometers east by northeast of Casper. One is located in the Shirley Basin, about 60 km south of Casper, and the remaining one is located in the Gas Hills, approximately 100 km west of Casper. The one-year intensive study included simultaneous measurement of several parameters: continuous measurement of atmospheric radon concentration near the ground at three locations, monthly 24-hour radon flux measurements from various surfaces, radium analyses of soil samples collected under each of the flux monitoring devices, monthly integrations of aerosols on dichotomous aerosol samplers, analysis of aerosol samplers for total dust loading, aerosol elemental and radiochemical composition, aerosol elemental composition by particle size, wind speed, wind direction, temperature, barometric pressure, and rainfall

    Space missions have a growing interest in putting multi-core processors onboard spacecraft. For many missions processing power significantly slows operations. We investigate how continual planning and scheduling algorithms can exploit multi-core processing and outline different potential design decisions for a parallelized planning architecture. This organization of choices and challenges helps us with an initial design for parallelizing the CASPER planning system for a mesh multi-core processor. This work extends that presented at another workshop with some preliminary results.

  14. Chromogenic assay for BAY 81-8973 potency assignment has no impact on clinical outcome or monitoring in patient samples. (United States)

    Kitchen, S; Katterle, Y; Beckmann, H; Maas Enriquez, M


    Essentials Discrepancies can exist in factor VIII activity measured by the one-stage or chromogenic assays. LEOPOLD trial data were used to assess clinical impact of BAY 81-8973 potency assignment assay. Efficacy was not affected by the assay used for potency assignment and dosing of BAY 81-8973. Either assay may be used to measure factor VIII activity after BAY 81-8973 infusion. Background Product-specific discrepancies have been reported for factor VIII (FVIII) activity determined with one-stage or chromogenic assays. Objective To assess the clinical impact of potency assignment of BAY 81-8973, a full-length, unmodified, recombinant human FVIII, by use of the chromogenic assay or chromogenic assay adjusted to mimic results obtained with the one-stage assay Patients/methods Patients aged 12-65 years with severe hemophilia A received BAY 81-8973 in LEOPOLD I (20-50 IU kg(-1) two or three times weekly [investigator decision]) and LEOPOLD II (randomized to 20-30 IU kg(-1) twice weekly, 30-40 IU kg(-1) three times weekly, or on-demand treatment). Both trials included two 6-month crossover periods in which potency labeling was determined with the chromogenic substrate assay as per the European Pharmacopoeia (CS/EP) or the chromogenic substrate assay adjusted to mimic results obtained with the one-stage assay (CS/ADJ). The annualized bleeding rate (ABR) and FVIII incremental recovery were assessed by the use of pooled data. Results The analysis was perfomed on 121 patients. Median (quartile [Q] 1; Q3) ABRs during the CS/EP and CS/ADJ periods were 1.98 (0; 5.92) and 1.98 (0; 7.34), respectively. The mean incremental recovery was > 2 IU dL(-1) per IU kg(-1) in both periods with the use of either assay for postinfusion FVIII measurements. The median (Q1; Q3) chromogenic/one-stage assay recovery ratio was 1.054 (0.892; 1.150) for the CS/EP period when a plasma standard was used for calibration. Conclusions No impact on the ABR was observed with chromogenic-based as compared

  15. Geomorphological and hydrological implications of a given hydraulic geometry relationship, beyond the power-law (United States)

    Kim, JongChun; Paik, Kyungrock


    Channel geometry and hydraulic characteristics of a given river network, i.e., spatio-temporal variability of width, depth, and velocity, can be described as power functional relationships of flow discharge, named 'hydraulic geometry' (Leopold and Maddock, 1953). Many studies have focused on the implication of this power-law itself, i.e., self-similarity, and accordingly its exponents. Coefficients of the power functional relationships, on the contrary, have received little attention. They are often regarded as empirical constants, determined by 'best fitting' to the power-law without significant scientific implications. Here, we investigate and claim that power-law coefficients of hydraulic geometry relationships carry vital information of a given river system. We approach the given problem on the basis of 'basin hydraulic geometry' formulation (Stall and Fok, 1968) which decomposes power-law coefficients into more elementary constants. The linkage between classical power-law relationship (Leopold and Maddock, 1953) and the basin hydraulic geometry is provided by Paik and Kumar (2004). On the basis of this earlier study, it can be shown that coefficients and exponents of power-law hydraulic geometry are interrelated. In this sense, we argue that more elementary constants that constitute both exponents and coefficients carry important messages. In this presentation, we will demonstrate how these elementary constants vary over a wide range of catchments provided from Stall and Fok (1968) and Stall and Yang (1970). Findings of this study can provide new insights on fundamental understanding about hydraulic geometry relationships. Further, we expect that this understanding can help interpretation of hydraulic geometry relationship in the context of flood propagation through a river system as well. Keywords: Hydraulic geometry; Power-law; River network References Leopold, L. B., & Maddock, T. J. (1953). The hydraulic geometry of stream channels and some physiographic

  16. Evaluation of the National Weather Service Extreme Cold Warning Experiment in North Dakota. (United States)

    Chiu, Cindy H; Vagi, Sara J; Wolkin, Amy F; Martin, John Paul; Noe, Rebecca S


    Dangerously cold weather threatens life and property. During periods of extreme cold due to wind chill, the National Weather Service (NWS) issues wind chill warnings to prompt the public to take action to mitigate risks. Wind chill warnings are based on ambient temperatures and wind speeds. Since 2010, NWS has piloted a new extreme cold warning issued for cold temperatures in wind and nonwind conditions. The North Dakota Department of Health, NWS, and the Centers for Disease Control and Prevention collaborated in conducting household surveys in Burleigh County, North Dakota, to evaluate this new warning. The objectives of the evaluation were to assess whether residents heard the new warning and to determine if protective behaviors were prompted by the warning. This was a cross-sectional survey design using the Community Assessment for Public Health Emergency Response (CASPER) methodology to select a statistically representative sample of households from Burleigh County. From 10 to 11 April 2012, 188 door-to-door household interviews were completed. The CASPER methodology uses probability sampling with weighted analysis to estimate the number and percentage of households with a specific response within Burleigh County. The majority of households reported having heard both the extreme cold and wind chill warnings, and both warnings prompted protective behaviors. These results suggest this community heard the new warning and took protective actions after hearing the warning.

  17. Navigating the Path of Totality - Results and Lessons Learned from the 2017 Eclipse Broadcast, Webcast, Mobile App and Online Production (United States)

    Semper, R.; Higdon, R.


    The 2017 total solar eclipse provided unique opportunity to provide public outreach about astronomy, heliophysics, and scientific discovery. The Navigating the Path of Totality project was designed to produce eclipse related educational resources including live video feeds and distribute them to museums, schools, libraries and the public through online and broadcast media. Using special telescope video camera setups, five feeds were produced including a live one hour English program and in parallel a live one hour Spanish program from Casper, WY with a cutaway to Madras, OR, complete (C1-C4) telescope only feeds from both Madras, OR and Casper, Wy, and a complete (C1-C4) telescope only feed with live musical sonification and accompaniment by the Kronos Quartet. Images from the live feeds were made available on the NASA Website, NASA TV, Exploratorium website, Exploratorium Solar Eclipse mobile app, local television and in museums, libraries and schools worldwide. Associated educational video material including images from the 2016 total eclipse from Micronesia was produced and disseminated. In this talk we will discuss the evaluation results including an examination of the effectiveness of the digital strategy of many mobile channels and mobile apps using different analytics including IBM Watson social media analytics services. We will also present the lessons learned from the project.

  18. Laser enrichment: a new path to proliferation

    International Nuclear Information System (INIS)

    Casper, B.M.


    The use of lasers to obtain enriched uranium is an easier and cheaper method than methods currently in use. The immediate concern is that it could promote easy access to nuclear weapons by countries that do not presently have them. Mr. Casper feels that the U.S. government is working against itself; while the State Department is seeking to block one path to proliferation, ERDA laboratories are developing new technology that could open another. The proliferation implications have not been factored in a serious way into the decisions to proceed with this research. It is also clear that the United States does not now have a comprehensive policy that deals with all potentially important paths to proliferation, including laser enrichment. Mr. Casper states that there is still time to stop and consider whether laser enrichment should be developed, in light of its broader consequences. But this will not happen if the decisions are left exclusively in the hands of those promoting the technology, the author says. It is just this sort of situation that prompted the creation of several government institutions to provide independent assessments of new technologies. The Office of Technology Assessment, the Nuclear Regulatory Commission, and the Arms Control and Disarmament Agency all have the authority to intervene. Laser enrichment provides a good test of these institutions and of the viability of the concept of technology assessment. The status, benefits and risks, and the policy needed on laser research are discussed

  19. Bloomsday: James Joyce's Ulysses Celebrated as Theatrical Event

    Directory of Open Access Journals (Sweden)

    Willmar Sauter


    Full Text Available James Joyce had decided that 16 June 1904 should be the one day in the life of Leopold Bloom, about which he wrote his 800 page novel Ulysses. In his book, Joyce actually followed Mr Bloom that entire day, from his getting up and having the nowadays famous kidney breakfast, to the late evening, when he had to break into his own house on 7 Eccle Street to have a drink with Stephen Dedalus, the other main figure of the novel. The centenary of that very day took, accordingly, place in 2004. I have borrowed the identity of Mr Bloom to describe some street scenes from the centennial celebrations of Bloomsday in Dublin. After this intro-ductory presentation, part two of this article will attempt to analyse Bloomsday in terms of a Theatrical Event, embedded in an unusual and striking playing culture. In a third part, Mr Bloom will once more be allowed to make some concluding comments.

  20. Kaspar Schott's "encyclopedia of all mathematical sciences" (United States)

    Knobloch, Eberhard


    In 1661, Kaspar Schott published his comprehensive textbook "Cursus mathematicus" in Würzburg for the first time, his "Encyclopedia of all mathematical sciences". It was so successful that it was published again in 1674 and 1677. In its 28 books, Schott gave an introduction for beginners in 22 mathematical disciplines by means of 533 figures and numerous tables. He wanted to avoid the shortness and the unintelligibility of his predecessors Alsted and Hérigone. He cited or recommended far more than hundred authors, among them Protestants like Michael Stifel and Johannes Kepler, but also Catholics like Nicolaus Copernicus. The paper gives a survey of this work and explains especially interesting aspects: The dedication to the German emperor Leopold I., Athanasius Kircher's letter of recommendation as well as Schott's classification of sciences, explanations regarding geometry, astronomy, and algebra.

  2. Music, Mechanism, and the "Sonic Turn" in Physical Diagnosis. (United States)

    Pesic, Peter


    The sonic diagnostic techniques of percussion and mediate auscultation advocated by Leopold von Auenbrugger and R. T. H. Laennec developed within larger musical contexts of practice, notation, and epistemology. Earlier, François-Nicolas Marquet proposed a musical notation of pulse that connected felt pulsation with heard music. Though contemporary vitalists rejected Marquet's work, mechanists such as Albrecht von Haller included it into the larger discourse about the physiological manifestations of bodily fluids and fibers. Educated in that mechanistic physiology, Auenbrugger used musical vocabulary to present his work on thoracic percussion; Laennec's musical experience shaped his exploration of the new timbres involved in mediate auscultation. © The Author 2015.

  3. The history and evolution of radiotherapy and radiation oncology in Austria

    International Nuclear Information System (INIS)

    Kogelnik, H. Dieter


    Austria has a longstanding and eventful history in the field of radiotherapy and radiation oncology. The founder of radiotherapy, Leopold Freund, began his well-documented first therapeutic irradiation on November 24, 1896, in Vienna. He also wrote the first textbook of radiotherapy in 1903. Further outstanding Viennese pioneers in the fields of radiotherapy, radiobiology, radiation physics, and diagnostic radiology include Gottwald Schwarz, Robert Kienboeck, and Guido Holzknecht. Because many of the leading Austrian radiologists had to emigrate in 1938, irreparable damage occurred at that time for the medical speciality of radiology. After World War II, the recovery in the field of radiotherapy and radiation oncology started in Austria in the early sixties. Eleven radiotherapy centers have been established since that time, and an independent society for radio-oncology, radiobiology, and medical radiophysics was founded in 1984. Finally, in March 1994, radiotherapy-radio-oncology became a separate clinical speciality

  4. A Bridge Back to the Future: Public Health Ethics, Bioethics, and Environmental Ethics. (United States)

    Lee, Lisa M


    Contemporary biomedical ethics and environmental ethics share a common ancestry in Aldo Leopold's and Van Rensselaer Potter's initial broad visions of a connected biosphere. Over the past five decades, the two fields have become strangers. Public health ethics, a new subfield of bioethics, emerged from the belly of contemporary biomedical ethics and has evolved over the past 25 years. It has moved from its traditional concern with the tension between individual autonomy and community health to a wider focus on social justice and solidarity. Public health has a broad focus that includes individual, community, and environmental health. Public health ethics attends to these broad commitments reflected in the increasing concern with the connectedness of health of individuals to the health of populations, to the health of animals, to the health of the environment; it is well situated to reconnect all three "fields" of ethics to promote a healthier planet.

The global water crisis is the main feature of this paper.

  6. Ni ética ambiental, ni valores. La reivindicación de Hans Jonas para la ética ambiental hecha por Eric Pommier, considerada desde la crítica de Heidegger al concepto de valor

    Directory of Open Access Journals (Sweden)

    Richard Ayala-Ardila


    Full Text Available En este trabajo se cuestiona tanto a la ética ambiental como a la filosofía ambiental desde la crítica hecha por Martin Heidegger al concepto de valor; tal cuestionamiento es precedido por una presentación de las consideraciones de Eric Pommier sobre la ética ambiental, lo cual implica tratar su apreciación de la filosofía ambiental norteamericana (Leopold, Rolston III y Callicot, su lectura de la obra de Hans Jonas y su reivindicación de las ideas de este autor para la ética o para la filosofía ambiental. Se mostrará que los problemas fundamentales de la ética ambiental consisten en encontrar una manera de demostrar el valor intrínseco de la naturaleza y en lograr este objetivo sin hacer concesión alguna al dualismo ontológico.

  7. Making Culture Bloom

    Iain McCalman


    Full Text Available On 16 June 1904, exactly one hundred years before the establishment of CHASS, an Irish Jew of Hungarian extraction called Leopold Bloom set off on a twenty-four hour perambulation around the streets and bars of Dublin. This fictional incident is the basis of James Joyce’s Ulysses, the greatest novel of modern times. It has also given rise to Bloomsday, a kind of Irish literary holy day celebrated in cities all around the world. It was a specially appropriate moment for us to celebrate the birth of our new peak body, because Bloomsday provides a perfect parable for why the Australian public and government should cherish our sector.

    Full Text Available This paper aims to find some answers regarding the long term sustainability of the pension system. Romania’s pension system originates from the invalidity insurances and pension system designed by the German cancellor Otto Eduard Leopold von Bismark in 1889. From a European perspective, Romania has to fill an obvious gap regarding the reformation of the national public pension system. International experience, particularly of the last 130 years, indicates that, in actuality, multiple pension systems have been put into function in most of the world’s countries and which are diferenciated by some elements (organizing and managing the system, defyning pension rights, method of forming the resources, the pension’s level rapported to the average income etc. and after the eficacity degree dependent on internal influences, social, economic and demographic environment, and last but not least by the political factor.

  10. New K-Ar constraints on the onset of subsidence in the Canning Basin, Western Australia

    International Nuclear Information System (INIS)

    Shaw, R.D.; Tyler, I.M.; Griffin, T.J.; Webb, A.


    Structural mapping and reconnaissance K-Ar studies have helped to delineate and date the latest deformational stages (D4 and D5) in the King Leopold Orogen, to the north of the Canning Basin. The dates have been determined for schists selected from both contractional shear zones and from rocks metamorphosed to the lower greenschist facies during the final phase of basement deformation. These dates imply that the basement-deforming event started in the latest Precambrian to earliest Cambrian (ca 560 Ma), and that tectonism recurred in the latest Cambrian to earliest Ordovician (ca 500 Ma). The final contractional deformation is slightly older than the oldest-known sedimentary rocks in the basin (latest Tremadoc), and helps to define the time that basin subsidence started. 23 refs., 3 tabs., 2 figs

    Harms, J.E.; Milton, D.J.; Ferguson, J.; Gilbert, D.J.; Harris, W.K.; Goleby, B.


    Goat Paddock, a crater slightly over 5 km in diameter (18??20??? S, 126??40???E), lies at the north edge of the King Leopold Range/Mueller Range junction in the Kimberley district, Western Australia (Fig. 1). It was noted as a geological anomaly in 1964 during regional mapping by the Bureau of Mineral Resources, Geology and Geophysics and the Geological Survey of Western Australia. The possibility of its being a meteorite impact crater has been discussed1, although this suggestion was subsequently ignored2. Two holes were drilled by a mining corporation in 1972 to test whether kimberlite underlay the structure. Here we report the findings of five days of reconnaissance in August 1979 which established that Goat Paddock is a cryptoexplosion crater containing shocked rocks and an unusually well exposed set of structural features. ?? 1980 Nature Publishing Group.

    Full Text Available In reason of concernment increase with the environment conservation and quality improvement, also with the health human being protection, organizations of all sizes are focusing its attention to potential environmental impacts of its activities, products or services. For this motive, the aim in this paper is to make an environment evaluation of discarding and destination of residues generated for painting process of a petroliferous equipment industry. Three methods of assessment were used: aspects and impacts spreadsheet construction, modified Leopold matrices construction, and quantification of solid waste generation. The deriving dangerous solid waste generation of used painting process is the environmental aspect that requires greater attention, being necessary to develop new based measures of control in clean technology principles. The integration of the evaluation methods allowed a fast and hierarchyzed visualization of these impacts, beyond allowing an evaluation of the adopted measures of control.

  14. Congomania in Academia. Recent Historical Research on the Belgian Colonial Past

    Directory of Open Access Journals (Sweden)

    S.E. Kiangu


    Full Text Available The Congo has recently been the subject of much academic research. This article discusses the major trends and developments. It primarily focuses on the Congo crisis of 1960, which was commemorated in 2010 and has been inquired into by many historians, including American, British and Russian ones. A comparison of their conclusions reveals that Flanders has largely come to terms with its colonial past, but that the French-speaking community has a more problematic memory. Belgian academia, by contrast, has left the old controversies about Leopold II and Lumumba behind and embarked on the path of new imperial history. It approaches the Congolese past from new angles and with new paradigms, such as reciprocity, science, exhibition, representation, etc. Congolese academia suffers from the economic problems of the country, but has managed to produce a number of studies, focusing mainly on regions, religion, and resistance. Strikingly, Congolese historians have little criticism of the colonial era.

    Full Text Available This article examines so-called colonial discourses in Belgium related to the former Sub-Saharan colony owned by Leopold II of Belgium which today is known as the Democratic Republic of Congo (DR Congo or the Congo-Kinshasa. Having introduced the colonial history of the DR Congo from the 15th century until 1910, the study starts with a discussion of Van den Braembussche’s concept of a ‘historical taboo’ and four ways of engaging with such implicit interdictions. Finally, an empirical analysis of colonial discourses in Belgium from the 1890s until today will be presented in conjunction with Belgium’s linguistic-cultural division, taking into account age-related divergence.

  16. Interdisciplinary Adventures in Perceptual Ecology (United States)

    Bocast, Christopher S.

    A portfolio dissertation that began as acoustic ecology and matured into perceptual ecology, centered on ecomusicology, bioacoustics, and translational audio-based media works with environmental perspectives. The place of music in Western eco-cosmology through time provides a basis for structuring an environmental history of human sound perception. That history suggests that music may stabilize human mental activity, and that an increased musical practice may be essential for the human project. An overview of recent antecedents preceding the emergence of acoustic ecology reveals structural foundations from 20th century culture that underpin modern sound studies. The contextual role that Aldo Leopold, Jacob von Uexkull, John Cage, Marshall McLuhan, and others played in anticipating the development of acoustic ecology as an interdiscipline is detailed. This interdisciplinary aspect of acoustic ecology is defined and defended, while new developments like soundscape ecology are addressed, though ultimately sound studies will need to embrace a broader concept of full-spectrum "sensory" or "perceptual" ecology. The bioacoustic fieldwork done on spawning sturgeon emphasized this necessity. That study yielded scientific recordings and spectrographic analyses of spawning sounds produced by lake sturgeon, Acipenser fulvescens, during reproduction in natural habitats in the Lake Winnebago watershed in Wisconsin. Recordings were made on the Wolf and Embarrass River during the 2011-2013 spawning seasons. Several specimens were dissected to investigate possible sound production mechanisms; no sonic musculature was found. Drumming sounds, ranging from 5 to 7 Hz fundamental frequency, verified the infrasonic nature of previously undocumented "sturgeon thunder". Other characteristic noises of sturgeon spawning including low-frequency rumbles and hydrodynamic sounds were identified. Intriguingly, high-frequency signals resembling electric organ discharges were discovered. These

  17. Situating trends in environmental education within the ecological debate

    International Nuclear Information System (INIS)

    Faulconer, T.


    For centuries there have been two philosophical orientations toward nature; one assumes humans to be the rightful owners and managers of nature, and the other is founded on a belief that humans are equal citizens within the earth's biotic community. Today these two approaches are located within reform environmentalism and deep ecology. In 1948, Aldo Leopold wrote an essay entitled open-quotes The Land Ethicclose quotes which proposed that humans include the land and its inhabitants within their circle of ethical concern. This essay has become a focal point of the debate between these two philosophies. The purpose of this study is to discover and describe the conceptual trends in environmental education since Leopold published open-quotes The Land Ethic.close quotes Eighty-two articles, published in educational journals from 1950 to 1990, were analyzed to determine whether they expressed a reform environmentalism orientation or a deep ecology perspective. Articles were selected which provided a statement of the purposes and goals of conservation education and environmental education. Until 1969, articles were drawn from a wide variety of educational journals. After 1969, the selection was limited to articles in The Journal of Environmental Education when that journal became the leading forum for environmental education discourse. The results showed that in the 1950s and 1960s the focus was almost entirely on wise-use conservation and reform environmentalism. In the last two decades, however, even though reform environmentalism remained a dominant influence, there has been a definite trend toward incorporating deep ecology concepts in this educational discourse. Further research is needed to determine how these ideas influence curriculum design and instructional practice

    Full Text Available RESUMEN: El artículo es una introducción a la lectura de la magna Enciclopedia dei Papi, obra presentada en Bolonia en el año 2001. Biografía e historia tienen en el caso del Papado una tradición antigua. La construcción del poder papal pasó por la prohibición del análisis crítico y el control de las fuentes documentales, las cuales sólo estuvieron al alcance de proyectos apologéticos. La Edad Moderna se caracterizó por una deliberada exclusión del Papado del conocimiento historiográfico. El rechazo de la Reforma protestante al poder papal no se basó en investigaciones históricas sino en la más oscura tradición profética. La historia del Papado propiamente dicha comenzó con la inspiración luterana de Leopold von Ranke y la respuesta católica de Ludwing Pastor.ABSTRACT: The article is an introduction to the reading of magna Encyclopedia dei Papi, work presented in Bologna in 2001. Biography and history are part of an old tradition in the case of the Pope state. The institution of the Pope power passed through the prohibition of the critical analysis and the control of the documentary sources, which only were within reach of apologetic projects. The Modern Age was characterized by a deliberate exclusion of the Pope of the historiographic knowledge. The rejection of the papal power by the protestant Reformation was not based on historical investigations but on the darkest prophetic tradition. The history of the Papal state itself began with the Lutheran inspiration of Leopold von Ranke and the catholic answer of Ludwing Pastor.

  19. Two-dimensional coherence analysis of magnetic and gravity data from the Cascer Quadrangle, Wyoming. Final report

    International Nuclear Information System (INIS)

    QEB, Inc. has completed a two-dimensional coherence analysis of gravity and magnetic data from the Casper, Wyoming NTMS quadrangle. Magnetic data from an airborne survey were reduced to produce a Residual Magnetic map, and gravity data obtained from several sources were reduced to produce a Complete Bouguer Gravity map. Both sets of data were upward continued to a plane one kilometer above the surface; and then, to make the magnetic and gravity data comparable, the magnetic data were transformed to pseudo-gravity data by the application of Poisson's relationship for rocks that are both dense and magnetic relative to the surrounding rocks. A pseudo-gravity map was then produced and an analysis made of the two-dimensional coherence between the upward continued Bouguer gravity and the pseudo-gravity data. Based on the results of the coherence analysis, digital filters were designed to either pass or reject wavelength bands with high coherence

    International Nuclear Information System (INIS)

    De Santis, S.; Byrd, J.M.; Billing, M.; Palmer, M.; Sikora, J.; Carlson, B.


    A relatively new technique for measuring the electron cloud density in storage rings has been developed and successfully demonstrated (S. De Santis, J.M. Byrd, F. Caspers, A. Krasnykh, T. Kroyer, M.T.F. Pivi, and K.G. Sonnad, Phys. Rev. Lett. 100, 094801 (2008).). We present the experimental results of a systematic application of this technique at the Cornell Electron Storage Ring Test Accelerator. The technique is based on the phase modulation of the TE mode transmitted in a synchrotron beam pipe caused by the periodic variation of the density of electron plasma. Because of the relatively simple hardware requirements, this method has become increasingly popular and has been since successfully implemented in several machines. While the principles of this technique are straightforward, quantitative derivation of the electron cloud density from the measurement requires consideration of several effects, which we address in detail.

    On-water demonstration of a wide range of mission-proven, advanced technologies at TRL 5+ that provide a total integrated, modular approach to effectively address the majority of the key needs for full mission-level autonomous, cross-platform control of USV s. Wide baseline stereo system mounted on the ONR USSV was shown to be an effective sensing modality for tracking of dynamic contacts as a first step to automated retrieval operations. CASPER onboard planner/replanner successfully demonstrated realtime, on-water resource-based analysis for mission-level goal achievement and on-the-fly opportunistic replanning. Full mixed mode autonomy was demonstrated on-water with a seamless transition between operator over-ride and return to current mission plan. Autonomous cooperative operations for fixed asset protection and High Value Unit escort using 2 USVs (AMN1 & 14m RHIB) were demonstrated during Trident Warrior 2010 in JUN 2010

  6. Prediction of the net radon emission from a model open pit uranium mine

    International Nuclear Information System (INIS)

    Nielson, K.K.; Perkins, R.W.; Schwendiman, L.C.; Enderlin, W.I.


    Radon emission from a model open pit uranium mining operation has been estimated by applying radon exhalation fluxes measured in an open pit uranium mine to the various areas of the model mine. The model mine was defined by averaging uranium concentrations, mine dimensions, production and procedural statistics for eight major open pit uranium mines in the Casper, Wyoming area. The resulting emission rates were 630 Ci/RRY (1 RRY one = 1000-MW(e) reactor operating for 1 year) during mining operations and 26 Ci/RRY/y after abandoment of the mine assuming 100% recovery of U 3 O 8 from the ore, or 700 Ci/RRY and 29 Ci/RRY/y assuming 90.5% recovery

    Thick Phaneorozoic sediments (greater than 17,000 feet) fill the northwest-trending Powder River Basin, which is the dominant tectonic structure in the study area. Lower Tertiary sediments comprise over 90% of the exposed units at the surface of the Basin. Small portions of the Bighorn Uplift, Casper Arch, and Porcupine Dome occupy the western edge of the study area. Numerous small claims and prospects are found in the Pumpkin Buttes - Turnercrest District at the south end of the study area (northeastern Arminto quadrangle). No economic deposits of uranium are known to exist in the area, according to available literature. Interpretation of the radiometric data resulted in 62 statistical uranium anomalies listed for this area. Most anomalies are found in the southern half of the study area within the Tertiary Fort Union and Wasatch Formations. Some are found in Cretaceous sediments in the adjoining uplifts to the west of the Basin

  10. Abdominal Twin Pressure Sensors for the assessment of abdominal injuries in Q dummies: in-dummy evaluation and performance in accident reconstructions. (United States)

    Beillas, Philippe; Alonzo, François; Chevalier, Marie-Christine; Lesire, Philippe; Leopold, Franck; Trosseille, Xavier; Johannsen, Heiko


    The Abdominal Pressure Twin Sensors (APTS) for Q3 and Q6 dummies are composed of soft polyurethane bladders filled with fluid and equipped with pressure sensors. Implanted within the abdominal insert of child dummies, they can be used to detect abdominal loading due to the belt during frontal collisions. In the present study - which is part of the EC funded CASPER project - two versions of APTS (V1 and V2) were evaluated in abdominal belt compression tests, torso flexion test (V1 only) and two series of sled tests with degraded restraint conditions. The results suggest that the two versions have similar responses, and that the pressure sensitivity to torso flexion is limited. The APTS ability to detect abdominal loading in sled tests was also confirmed, with peak pressures typically below 1 bar when the belt loaded only the pelvis and the thorax (appropriate restraint) and values above that level when the abdomen was loaded directly (inappropriate restraint). Then, accident reconstructions performed as part of CASPER and previous EC funded projects were reanalyzed. Selected data from 19 dummies (12 Q6 and 7 Q3) were used to plot injury risk curves. Maximum pressure, maximum pressure rate and their product were all found to be injury predictors. Maximum pressure levels for a 50% risk of AIS3+ were consistent with the levels separating appropriate and inappropriate restraint in the sled tests (e.g. 50% risk of AIS3+ at 1.09 bar for pressure filtered CFC180). Further work is needed to refine the scaling techniques between ages and confirm the risk curves.

  11. Preliminary draft industrial siting administration permit application: Socioeconomic factors technical report. Final technical report, November 1980-May 1982. [Proposed WyCoalGas project in Converse County, Wyoming

    Energy Technology Data Exchange (ETDEWEB)


    Under the with-project scenario, WyCoalGas is projected to make a difference in the long-range future of Converse County. Because of the size of the proposed construction and operations work forces, the projected changes in employment, income, labor force, and population will alter Converse County's economic role in the region. Specifically, as growth occurs, Converse County will begin to satisfy a larger portion of its own higher-ordered demands, those that are currently being satisfied by the economy of Casper. Business-serving and household-serving activities, currently absent, will find the larger income and population base forecast to occur with the WyCoalGas project desirable. Converse County's economy will begin to mature, moving away from strict dependence on extractive industries to a more sophisticated structure that could eventually appeal to national, and certainly, regional markets. The technical demand of the WyCoalGas plant will mean a significant influx of varying occupations and skills. The creation of basic manufacturing, advanced trade and service sectors, and concomitant finance and transportation firms will make Converse County more economically autonomous. The county will also begin to serve market center functions for the smaller counties of eastern Wyoming that currently rely on Casper, Cheyenne or other distant market centers. The projected conditions expected to exist in the absence of the WyCoalGas project, the socioeconomic conditions that would accompany the project, and the differences between the two scenarios are considered. The analysis is keyed to the linkages between Converse County and Natrona County.

    Full Text Available Apoyándonos en la noción de "esfera" de Slotedijk, analizamos la protección constituida por los moles. La libertad de elegir en el mol no tiene relación con la libertad individual propuesta por John Stuart Mill; ni con la anarco-individualista propuesta por Henry David Thoreau o incluso por Aldo Leopold en el elogio que éste realiza de la autonomía del pionero estadounidense. En la libertad de elegir en el mol han caducado todas las aventuras y las relaciones humanas se convierten en lo que Sloterdijk denomina "relaciones cristalizadas", bajo el proyecto del aburrimiento normativo poshistórico. La expresión económico-filosófica del mundo poshistórico es la idea de libertad de elegir, enunciada por Milton Friedman. El mol, actual Palacio de Cristal, es como una enciclopedia ilustrada, que exhibe, en orden y sin peligros, el conjunto, ya no del saber, sino de los bienes disponibles. Con ello, se modifica la condición humana.Based on the Sloterdijk's concept of sphere, we analyse the protection provided by the malls. Nevertheless, the freedom of choosing in a mall does not have any relation to liberty as it was proposed by John Stuart Mill, neither to the anarcho-individualist one proposed by Henry David Thoreau, nor even to that one proposed by Aldo Leopold, when he praises the authonomy of American pioneer. In the freedom process of choosing in the mall, all adventures perish and human relations become what Sloterdijk denominated "crystalised relations", under a post-historic normative boring project. The economic-philosophical expression of post-historic world is the idea of freedom of choosing, conceived by Milton Friedman. The mall, the current Crystal Palace, is like an enlightened encyclopaedia, which shows, in order and without dangers, the totality, no longer of knowledge, but of available goods. In this way, human condition has modified.

    to the existence of our society and that such should be undertaken in an environmentally and economically responsible manner." However, statements such as these still focus primarily on the value of the earth to generations of humans, rather than on the earth itself. They remain far from meeting addressing our obligation to the land as summarized, for example, by Aldo Leopold, widely regarded as the principal founder of the American conservation movement: "The individual is a member of a community of interdependent parts. The land ethic simply enlarges the boundaries of the community to include soils, waters, plants and animals, or collectively the land." In this poster, we compare and contrast the various existing codes and suggest ways in which ethical obligations to the community itself, as defined by Leopold, could be more clearly incorporated.

    The existence of balance, coordination and required order among natural elements is one of the key factors in the ecosystem. If this balance is disturbed under certain circumstances, it will damage the structure of living existences and more specifically human beings. Since a half century ago, factors such as important economical and industrial activites, advanced technologies together with growing population and lack of concordance among different couhntries to take optimal advantage of the existing natural resources have distrubed the balance in the ecosystem. As a result, man has caused many problems such as high death tolls and arduous diseases due to the different pollutions in water, air, land, sound, temperature, etc and factors such as erosion, desert, expansion, floods, extinction of plant and animal species, ozone layer destruction, global warming, sea level rise and greenhouse gases increase. Environmental Impact Assessment (EIA) is to recognize and assess systematic consequences of projects and programs on elements like physicochemical, biological, cultural, economical and social phenomena in th environment; in other words it is a way or method to determine the direction of predication and assessment of environmental impacts of activities on the environmental health of the ecosystem affecting human lives. In this study, and environmental impact assessment of the establishment of the Shahzand Industrial Estate in Arak at the central part of Iran was investigated. After collection of data and analysis of the findings, the positive and negative impacts resulting from establishment of the indutrial estate were investigated using the Leopold Matrix and Scaling checklist methods providing the managerial solutions in order to minimize the harmful environmental impacts. The existing environmental situation was investigated and then environmental impact alternatives were determined. This was done in regard to the amount and kind of predicted pollution for the

  16. Detecting Breech Presentation Before Labour: Lessons From a Low-Risk Maternity Clinic. (United States)

    Ressl, Bill; O'Beirne, Maeve


    Evaluation of fetal position is an important part of prenatal care. A woman with a breech presentation may need referral for external cephalic version, for assisted breech delivery, or to schedule a Caesarean section. In many centres, a breech presentation undetected until labour will result in an emergency Caesarean section, a less desirable alternative for both the mother and the health care system. The anecdotal reports of undiagnosed breech presentations at a busy maternity clinic prompted a study to quantify the missed breech presentations and to evaluate the effectiveness of the current detection process, with the aim of allowing no more than 1% of breech presentations to remain undetected until labour. We performed a retrospective analysis of 102 breech deliveries over a 14 month period to quantify missed breech presentations, and used a prospective physician survey documenting how fetal presentation was determined at 186 prenatal visits over four months to analyze the current detection process. We found that approximately 8% of breech presentations were undetected until labour. We concluded that within the limitations of the small sample size evaluated, the current practice of using a vaginal examination to verify fetal presentation determined by abdominal palpation (Leopold's manoeuvres) may not be more accurate than abdominal palpation alone. The current detection process resulted in an unacceptably high rate of missed breech presentations. The results of this study prompted the clinic's acquisition of bedside ultrasound capability to assess fetal position.

  17. [The dawn of radiotherapy, between strokes of genius, dramas and controversies]. (United States)

    Cosset, J-M


    Radiotherapy is 120 years old. A few months only after the discoveries of Roentgen, Becquerel and Marie and Pierre Curie, a few scientists tried to use the newly discovered rays to treat patients. The question of the name of the first "radiation therapist" remains debated. Although often proposed, Emil Grubbé from Chicago seems to have been disqualified. Leopold Freund from Vienna treated a benign cutaneous lesion. Finally, Victor Despeignes from Lyon appears to be the most serious candidate, having treated in 1896 a gastric cancer, and obtaining a very significant tumour regression. The pioneers of radiotherapy paid a heavy tribute to the development of the specialty; a number of them appears on the - most probably incomplete - list of 352 names engraved on the monument dedicated to the "radiation martyrs" in Hamburg. We must keep in mind that it is only within a few years that a handful of brilliant pioneers built the foundations on which radiotherapy could emerge.

  18. Designing an Effective Environmental Education Program that Meets the Needs of Stakeholders: A Case Study of the High Lonesome Ranch in DeBeque, Colorado (United States)

    Haley, Bethany M.

    A successful environmental education (EE) program is one that supports the mission of the parent organization, meets the needs of its audiences, and is effective at increasing environmental literacy. The High Lonesome Ranch (HLR), a private corporation that operates according to a mixed-use landscape model inspired by Aldo Leopold's land ethic, intends to develop an EE program that will operate within an associated nonprofit organization, the High Lonesome Institute (HLI), to further the mission of promoting a contemporary land ethic. Although HLR owners and staff are motivated to develop an EE program, there is currently no clear consensus regarding an overall vision for the program. The purpose of my thesis is to provide HLR owners and their advisors with a recommended design for the education program based on the missions of the HLR and HLI, sound EE theory, stakeholder feedback, and feasibility within the environment of the HLR. To accomplish this, I reviewed pertinent EE literature, reviewed the models used by existing EE programs, and undertook a two-pronged qualitative case study that gathered feedback from the major stakeholders in the HLR/HLI program. The case study included stakeholder interviews and a one-day facilitated charrette. Although feedback from stakeholders on specific program elements ranged widely, there was widespread support for an EE program at the HLR. From this research, I made a series of recommendations regarding how the HLR/HLI should proceed in development, specific program elements, and next steps in the process.

  19. Interactions between red light, abscisic acid, and calcium in gravitropism (United States)

    Leopold, A. C.; LaFavre, A. K.


    The effect of red light on orthogravitropism of Merit corn (Zea mays L.) roots has been attributed to its effects on the transduction phase of gravitropism (AC Leopold, SH Wettlaufer [1988] Plant Physiol 87:803-805). In an effort to characterize the orthogravitropic transduction system, comparative experiments have been carried out on the effects of red light, calcium, and abscisic acid (ABA). The red light effect can be completely satisfied with added ABA (100 micromolar) or with osmotic shock, which is presumed to increase endogenous ABA. The decay of the red light effect is closely paralleled by the decay of the ABA effect. ABA and exogenous calcium show strong additive effects when applied to either Merit or a line of corn which does not require red light for orthogravitropism. Measurements of the ABA content show marked increases in endogenous ABA in the growing region of the roots after red light. The interpretation is offered that red light or ABA may serve to increase the cytoplasmic concentrations of calcium, and that this may be an integral part of orthogravitropic transduction.

    The article is based on the Leopold Szondi theory (March 11, 1893 – January 24, 1986), who was a Hungarian psychiatrist. He is known for the psychological tool that bears his name, the Szondi test. He developed a form of depth psychology that had some prominence in Europe in the mid–20th century, but has been ignored for the most part), the study seeks to correlate the szondian test results with the imagistic ones on a wide–range pathology. In the Neurosurgery Department, patients are investigated using modern exploration methods (MRI, CTscan, and computed EEG, etc.) in order to identify possible somatic lesions. The study's subjects selected during 2000–2004 from the patients admitted and investigated for neurosurgical conditions; they were divided into two subgroups, based on whether the organic lesions were or were not present (the independent variable). The exclusion criterion was a lesion due to external causes. Statistically meaningful there are seven types of Ego profiles, in relation with the lesion: the archaic ego [0 –], the inhibited ego [– +], the adaptive ego [– –], the narcissist ego [+ +], the identified ego [+/– 0], the fugitive ego [+/– –] and the possessed ego [0 +]. The nexus in the destiny's analysis description highlights the dialectic between the Ego's functions and the drived dangers when facing the demands of the concrete reality. PMID:20945811

  1. Chloroform anesthesia and the Saville Kent murder in 1860. (United States)

    Hutcheon, Duncan E


    The discovery of the anesthetic properties of chloroform by Sir James Simpson is one of the therapeutic triumphs of the 19th century. Queen Victoria requested chloroform anesthesia for the birth of her second son, Prince Leopold, and from then until the end of century chloroform was the most popular general anesthetic for obstetrics and surgery. Chloroform was so pleasant to inhale that it became a drug of abuse and was involved in all sorts of criminal activity. Despite its wide usage, chloroform was not thought to be part of the brutal murder of 3-year-old Saville Kent on the night of June 30, 1860, outside his manor house in southwest England. The events surrounding and after the murder have recently been documented by Kate Summerscale in a book entitled, "The Suspicions of Mr. Whicher," the Detective Inspector assigned to the case by Scotland Yard. According to Ms Summerscale's records, Mr Whicher ignored the possibility that chloroform was involved in Saville's death. However, evidence supports the view that chloroform played a critical role in the crime and indicates that the guilty plea by Samuel Kent's daughter, Constance, for which she spent 20 years to the day in prison, was as inaccurate as it was incomplete.

  2. Modernizing Natural History: Berkeley's Museum of Vertebrate Zoology in Transition. (United States)

    Sunderland, Mary E


    Throughout the twentieth century calls to modernize natural history motivated a range of responses. It was unclear how research in natural history museums would participate in the significant technological and conceptual changes that were occurring in the life sciences. By the 1960s, the Museum of Vertebrate Zoology at the University of California, Berkeley, was among the few university-based natural history museums that were able to maintain their specimen collections and support active research. The MVZ therefore provides a window to the modernization of natural history. This paper concentrates on the directorial transitions that occurred at the MVZ between 1965 and 1971. During this period, the MVZ had four directors: Alden H. Miller (Director 1940-1965), an ornithologist; Aldo Starker Leopold (Acting Director 1965-1966), a conservationist and wildlife biologist; Oliver P. Pearson (Director 1966-1971), a physiologist and mammalogist; and David B. Wake (Director 1971-1998), a morphologist, developmental biologist, and herpetologist. The paper explores how a diversity of overlapping modernization strategies, including hiring new faculty, building infrastructure to study live animals, establishing new kinds of collections, and building modern laboratories combined to maintain collections at the MVZ's core. The paper examines the tensions between the different modernization strategies to inform an analysis of how and why some changes were institutionalized while others were short-lived. By exploring the modernization of collections-based research, this paper emphasizes the importance of collections in the transformation of the life sciences.

The king was interested in this vast area only because of its huge natural sources. To got hold of them he forced natives to slave labour using only brutal methods, intimidation, terrorism and breaking human rights. His authoritarian regime was criticized, so the Belgian government decided in 1908 to take control over Congo. They annexed the colony and since that it was called Belgian Congo. For years the colony was intensively exploited by Belgium. The colonist brought minerals, gum, palm oil, ivory and first of all diamonds. Finally, in 1960 after the African revolution, Congo became independent country.The heritage of colonialism was the course of Africa. The rule of white people in Congo based on traditional local structures, what made the communication with natives much easier.

He decides to leave Edinburgh and go inland, where no one knows him. But before that he will knock on his female neighbour’s door, hoping she will give his attentions a positive reception.

  5. Review and resolution of some nomenclatural issues regarding the genus Psoroptes (Acari: Psoroptidae), scab-mites of domestic and wild mammals. (United States)

    OConnor, Barry M; Klimov, Pavel B


    Some classifications recognize a number of species in the scab-mite genus, Psoroptes, mites that are of considerable importance in livestock production and veterinary medicine. However, modern studies suggest that populations from some host species are not morphologically or genetically distinct, creating taxonomic confusion with older names, which treated mites from different hosts as separate species. We review the taxonomy and nomenclature of the genus and the two oldest binomens, most recently known as Psoroptes ovis and Psoroptes equi. Prior authors have attributed these names to various authorities, with most attributing both names to Hering (Nova Acta Phys-Med Acad Caesar Leopold-Carol Nat Curios 18(2):573-624, 1838). In particular, the priority between these names was recently a point of contention, with P. ovis being treated as junior synonym of P. equi. A review of all relevant nineteenth and twentieth century publications indicates, however, that these binomens should be cited as P. ovis (Viborg in Veterinair-Selskabets Skrifter 2:139-152, 1813) and P. equi (Raspail in Bull gener Theraput Med Chir 7:169-184, 1834), with the former having priority over the latter assuming their conspecificity. We also clarify attribution of the authorship and the type species of the genus Psoroptes.

    Steinmayr, Johann; Müller, Isolde; Posch, Thomas


    We give a brief overview of the development of astronomical research at the University of Graz from the 16th to the 18th century. This period is intimately connected to the activities of the Jesuit Order and to the counter-reformation in Inner Austria (a territory roughly corresponding to today's Styria, Carinthia, Slovenia and the County of Görz in Italy). Since the opening of the University in 1585, several Jesuits achieved distinction as mathematicians, physicists and astronomers in Graz. Among them are Paul Guldin, who corresponded with Johannes Kepler and died in Graz in 1643, as well as Leopold Biwald and Karl Tirnberger. Between 1745 and 1774, the Jesuit University of Graz also had a chair of astronomy and an observatory. The chair and the observatory were well endowed at the beginning, but later on neglected by their former funders and closed down after less than 30 years. Efforts to re-establish an observatory at Graz at the beginning of the 19th century failed. They were successful only towards the end of the 19th century, which is however a period beyond the scope of the present paper.

  7. The origins of radiotherapy: discovery of biological effects of X-rays by Freund in 1897, Kienböck's crucial experiments in 1900, and still it is the dose. (United States)

    Widder, Joachim


    The discovery of X-rays by Wilhelm Conrad Röntgen (1845-1923) was triggered by pursuing an anomalous phenomenon: arousal of fluorescence at a distance from tubes in which cathode rays were elicited, a phenomenon which suggested the existence of a new kind of ray other than cathode rays. The discovery of biological effects of these X-rays by Leopold Freund (1868-1943) was triggered by pursuit of the purportedly useless phenomenon of epilation and dermatitis ensuing from X-ray-diagnostic experiments that others had reported. The crucial experiments performed by Robert Kienböck (1871-1953) entailed the proof that X-ray-dose, not electric phenomena, was the active agent of biological effects ensuing when illuminating the skin using Röntgen tubes. For both the discovery of X-rays and the discovery of their biological effectiveness, priority did not matter, but understanding the physical and medico-biological significance of phenomena that others had ignored as a nuisance. Present discussions about the clinical relevance of improving the dose distribution including protons and other charged particles resemble those around 1900 to a certain degree.

  9. Chromatic interocular-switch rivalry. (United States)

    Christiansen, Jens H; D'Antona, Anthony D; Shevell, Steven K


    Interocular-switch rivalry (also known as stimulus rivalry) is a kind of binocular rivalry in which two rivalrous images are swapped between the eyes several times a second. The result is stable periods of one image and then the other, with stable intervals that span many eye swaps (Logothetis, Leopold, & Sheinberg, 1996). Previous work used this close kin of binocular rivalry with rivalrous forms. Experiments here test whether chromatic interocular-switch rivalry, in which the swapped stimuli differ in only chromaticity, results in slow alternation between two colors. Swapping equiluminant rivalrous chromaticities at 3.75 Hz resulted in slow perceptual color alternation, with one or the other color often continuously visible for two seconds or longer (during which there were 15+ eye swaps). A well-known theory for sustained percepts from interocular-switch rivalry with form is inhibitory competition between binocular neurons driven by monocular neurons with matched orientation tuning in each eye; such binocular neurons would produce a stable response when a given orientation is swapped between the eyes. A similar model can account for the percepts here from chromatic interocular-switch rivalry and is underpinned by the neurophysiological finding that color-preferring binocular neurons are driven by monocular neurons from each eye with well-matched chromatic selectivity (Peirce, Solomon, Forte, & Lennie, 2008). In contrast to chromatic interocular-switch rivalry, luminance interocular-switch rivalry with swapped stimuli that differ in only luminance did not result in slowly alternating percepts of different brightnesses.

  11. Beyond positivist ecology: toward an integrated ecological ethics. (United States)

    Norton, Bryan G


    A post-positivist understanding of ecological science and the call for an "ecological ethic" indicate the need for a radically new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental sciences because the recent work of "reflexive" ecological modelers shows that this requires a reconceptualization of the way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe it is appropriate for ecologists to examine the motives for their choices in developing models; this self-reflexive approach opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold, which shows that learning to "think like a mountain" involves a shift in both ecological modeling and in values and responsibility. An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals that neither of the widely accepted theories of environmental value-neither economic utilitarianism nor intrinsic value theory (environmental ethics)-provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive, and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate the models used to describe environmental change.

Projection of one's own body, as is suggested by phenomenological studies of Edith Stein and Leopold Blaustein, may consist in suspending the direct relation to Körper when the basis of identification is merely Leib, which we experience in dislocation, in an unclear connection with the border of the field of imagined space. An important feature of this situation is that during projection of the spectator's body into the field of an image to suspension is submitted not only the feeling of the body as a physical datum, but also space which remains as its real surrounding. The problems touched upon here can be considered as prolegomena to the phenomenology of a spectator-in-aspectacle.

    Wyklicky, H [Vienna Univ. (Austria). Inst. fuer Geschichte der Medizin


    Even before the turn of the century, the dermatologist Leopold Freund tried to treat a hairy naevus on the back of a child with the rays Roentgen had discovered in 1895 when all known forms of therapy had failed. Loss of hair, as desired, resulted therein. In order to prove that electric currents were not the effective agents, Freund abducted them and treated another part of the naevus pigmentosus piliferus, however, for a longer period in order to compensate for the supposed loss of energy. An ulcer resulted. A number of renowned researchers doubted the biological effect of the X-rays. Freund also began to doubt his original opinion and later even attacked his very own discovery. Only the findings of Robert Kienboeck after having carefully examined them, let Freund accept his former opinion again. Guido Holzknecht, recognized as a pioneer of X-ray diagnosis even before the First World War, occupied himself successfully with X-ray therapy under the influence of Kienboeck. He may be regarded as one of the world's first radiobiologists. Vincenz Czerny, of Austrian origin, and a pupil of Theodor Billroth, became a promotor of the X-ray therapy of malignant blastomas in Heidelberg. K.H. Kaercher, who has been head of the Department of Radiotherapy, Vienna University, for the past ten years is a graduate of this famous school.

  16. Scientists are From Venus, Journalists are From Mars: Bridging the Two Worlds (United States)

    Baron, N.


    Media coverage of issues ranging from climate change to evolution often shapes public awareness and opinions about these topics and the science behind them. While scientists can play a critical social role as a resource for journalists and as a valuable information source for the public, they are often frustrated with how their work is portrayed in the press or choose to avoid public discussions completely. In order for science-based policy measures to succeed, scientists must engage in these public discussions and learn how to communicate more effectively - not only with each other, but also with the media, the public, and policy makers. This requires being able to put themselves in the shoes of their audiences. This presentation will provide insights into the world of journalism and offer practical steps that scientists can take to ensure that their research will register on the public's radar screen. Presenter Nancy Baron, Lead Communications Trainer for the Aldo Leopold Program (ALLP) and Ocean Science Outreach Director for COMPASS works closely with leading scientists to help them communicate the contents and importance of their work more effectively and make their science "news" without compromising scientific integrity or credibility.

  17. Why social values cannot be changed for the sake of conservation (United States)

    Manfredo, Michael J.; Bruskotter, Jeremy T.; Teel, Tara L.; Fulton, David C.; Schwartz, Shalom H.; Arlinghaus, Robert; Oishi, Shigehiro; Uskul, Ayse K.; Redford, Kent; Kitayama, Shinobu; Sullivan, Leeann


    The hope for creating widespread change in social values has endured among conservation professionals since early calls by Aldo Leopold for a “land ethic.” However, there has been little serious attention in conservation to the fields of investigation that address values, how they are formed, and how they change. We introduce a social–ecological systems conceptual approach in which values are seen not only as motivational goals people hold but also as ideas that are deeply embedded in society's material culture, collective behaviors, traditions, and institutions. Values define and bind groups, organizations, and societies; serve an adaptive role; and are typically stable across generations. When abrupt value changes occur, they are in response to substantial alterations in the social–ecological context. Such changes build on prior value structures and do not result in complete replacement. Given this understanding of values, we conclude that deliberate efforts to orchestrate value shifts for conservation are unlikely to be effective. Instead, there is an urgent need for research on values with a multilevel and dynamic view that can inform innovative conservation strategies for working within existing value structures. New directions facilitated by a systems approach will enhance understanding of the role values play in shaping conservation challenges and improve management of the human component of conservation.

    Full Text Available Dorota Raczyńska, Leopold Glasner, Ewelina Serkies-Minuth, Magdalena A Wujtewicz, Kamila Mitrosz Department of Ophthalmology, Medical University of Gdansk, Gdansk, Poland Abstract: Extending life expectancy is a human achievement. It does however entail problems. Ophthalmic treatments are widely recognized as having a low risk of general complications. A classic example is cataract surgery, considered to be one of the safest and most frequently performed surgical procedures in the world. However, advanced age brings with it risks that should be considered before surgery. Eye operations, as with procedures on other organs, are largely dependent on the quality of surgical tissues. Therefore, the elderly are at increased risk of complications. Improved general health and postoperative follow-up with the use of noninvasive technologies such as optical coherence tomography translate into lower intraoperative risk and better postoperative prognosis. In this review, we discuss the impact of general health on operational prognosis, therapeutic problems, and technical difficulties which a surgeon and anesthesiologist may encounter in the process. We also consider new technology and strategies specifically aimed at treating eye conditions in the elderly.

  20. Why social values cannot be changed for the sake of conservation. (United States)

    Manfredo, Michael J; Bruskotter, Jeremy T; Teel, Tara L; Fulton, David; Schwartz, Shalom H; Arlinghaus, Robert; Oishi, Shigehiro; Uskul, Ayse K; Redford, Kent; Kitayama, Shinobu; Sullivan, Leeann


    The hope for creating widespread change in social values has endured among conservation professionals since early calls by Aldo Leopold for a "land ethic." However, there has been little serious attention in conservation to the fields of investigation that address values, how they are formed, and how they change. We introduce a social-ecological systems conceptual approach in which values are seen not only as motivational goals people hold but also as ideas that are deeply embedded in society's material culture, collective behaviors, traditions, and institutions. Values define and bind groups, organizations, and societies; serve an adaptive role; and are typically stable across generations. When abrupt value changes occur, they are in response to substantial alterations in the social-ecological context. Such changes build on prior value structures and do not result in complete replacement. Given this understanding of values, we conclude that deliberate efforts to orchestrate value shifts for conservation are unlikely to be effective. Instead, there is an urgent need for research on values with a multilevel and dynamic view that can inform innovative conservation strategies for working within existing value structures. New directions facilitated by a systems approach will enhance understanding of the role values play in shaping conservation challenges and improve management of the human component of conservation. © 2016 The Authors.

  1. Giuseppe Gradenigo: Much more than a syndrome! Historical vignette. (United States)

    Matis, Georgios K; de A Silva, Danilo O; Chrysou, Olga I; Karanikas, Michail A; Birbilis, Theodossios A


    Giuseppe Gradenigo (1859-1926), a legendary figure of Otology, was born in Venice, Italy. He soon became a pupil to Adam Politzer and Samuel Leopold Schenk in Vienna, demonstrating genuine interest in the embryology, morphology, physiopathology, as well as the clinical manifestations of ear diseases. In this paper, the authors attempt to highlight the major landmarks during Gradenigo's career and outline his contributions to neurosciences, which have been viewed as looking forward to the 20(th) century rather than awkward missteps at the end of the 19(th). Several rare photographs along with many non-English, more than a century old articles have been meticulously selected to enrich this historical journey in time. It was after Gradenigo that the well-known syndrome consisting of diplopia and facial pain due to a middle ear infection was named. However, Gradenigo was much more than a syndrome. Surprisingly, despite the fact that he is considered a pioneer of the Italian Otology of the late 19(th) and early 20(th) century, little is written of his life and his notable achievements in the English literature. Even though his name lives on nowadays only in the eponym "Gradenigo's syndrome," his accomplishments are much wider and cast him among the emblematic figures of science. His inherent tendency for discovering the underlying mechanisms of diseases and his vision of guaranteeing quality of services, professional proficiency, respect, and dedication toward the patients is in fact what constitutes his true legacy to the next generations.

  2. Diagnostic of ribeirão Mestre d’Armas sub-basin using two methods of rapid environmental assessment, Federal District, Central Brazil

    Directory of Open Access Journals (Sweden)

    Julio Cesar Joveli


    Full Text Available Rapid environmental assessments have been used to describe the quality and semi-quantitative attributes of the ecosystems along an environmental gradient using visual observations and few measurements. The aim of this study was to identify and measure anthropogenic impacts on ribeirão Mestre d’Armas sub-basin, Federal District, Central Brazil, and to propose its environmental zoning. This study was performed using two methods based on rapid environmental assessment: a rapid river assessment protocol, to evaluate in an integrated form the features of a lotic system section according to the conservation or degradation condition of the fluvial environment; and the Leopold matrix, to identify and evaluate the anthropogenic impacts. The environmental zoning of this sub-basin detected three areas: preserved, transition and urban areas. The environmental assessment revealed, the preserved area had lotic stretches with natural features under low magnitude of impacts, except on burned areas. In the transition area, there was a predominance of lotic stretches with altered features, due to agriculture and livestock activities of intermediate level of impacts. Finally, the urban area had altered and impacted lotic stretches of higher magnitude due to anthropogenic impacts. Thus, this study revealed large differences among the areas detected by environmental zoning, according to the methods used. These methods were considered complementary in relation to environmental diagnostic of the ribeirão Mestre d’Armas sub-basin.

  3. [Wolfgang Amadeus Mozart. A urological pathography]. (United States)

    Hatzinger, M; Häcker, A; Langbein, S; Bross, S; Honeck, P; Alken, P


    The death of Wolfgang Amadeus Mozart was mysterious from the very first day, and cause of wildest speculation and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. By means of letters from his father Leopold, his sister "Nannerl", himself and reports from his physicians and contemporaries, we would like to create a medical pathography. The rumour that Mozart was poisoned appeared soon after his early death at the age of 35 on December 5th 1791, and was kept up persistently. Accused were the physician van Swieten, Mozart's freemason's loge and the royal band master Salieri. Mozart, however, died due to chronic kidney disease and ultimately due to uraemia. Once the renal damage has reached a certain point, a minimum of additional stress leads to decompensation. This catastrophe occurs typically within the fourth decade of life. When listening to Mozart's music, we should remember that this apparently happy person was actually a premature adult robbed of his childhood, whose short life was an endless chain of indisposition, over fatigue, misery, concern and illness.

  4. Wolfgang Amadeus Mozart: the death of a genius. (United States)

    Hatzinger, Martin; Hatzinger, Jurgen; Sohn, Michael


    The early and unexpected death of Wolfgang Amadeus Mozart (Salzburg, 1756 - Vienna, 1791) was a mystery from the very first day and the subject of wildest speculations and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. The aim of this article was to recreate Mozart's pathography relying on the his correspondence with father Leopold and sister Nannerl and on reports from his physicians and contemporaries. The rumour that Mozart was poisoned followed shortly after his death on 5 December 1791, at the age of 35, and has survived to this day. The alleged culprits were his physician van Swieten, Mozart's freemasons lodge, and the Imperial Chapel Master Salieri. Mozart however died of chronic kidney disease and ultimately of uraemia. If kidney damage reaches a critical point, even a minimum additional stress can lead to its failure. This usually occurs in the fourth decade of life. Next time we listen to Mozart, we should remember that this apparently happy person was actually a precocious boy, ripped of his childhood, whose short life was an endless chain of complaints, fatigue, misery, concern, and malady.

  6. Scritture separate: autocensura testuale e imposizione visuale del bondage in Dino Buzzati

    Directory of Open Access Journals (Sweden)

    Antonio Lunardi


    Full Text Available The last period of Dino Buzzati's literary production (1960-1971 offers topics and stylistic forms that significantly diverge from the author's persona as prematurely proposed by criticism. Buzzati's prose here includes erotic and sensuous themes, while the author adds some visual elements that become increasingly pivotal in their experimentalism.  This twist on contents and forms reaches is apex in some images of bondage proposed in Buzzati's "opere doppie" (Coglitore:  Le storie dipinte, Poema a fumetti e I miracoli di Val Morel. The drawings in the books are frequently explicit, but bondage is never present in the text, where nothing but distant allusions to it can be found. Moving from Gius Gargiulo's work on the topic, this study interrogates this feature of the works going beyond the level of autocensorship. I will propose to read Buzzati's formal choice through the concepts of aesthetism and suspension that Gilles Deleuze recognizes as peculiar of masochism in his study on Leopold von Sacher-Masoch Masochism: Coldness and Cruelty. Buzzati's works are therefore contextualized in literary and cinematographic Italian production between 1965 and 1975, with reference to Gianni Celati's Il chiodo in testa and Liliana Cavani's Il portiere di notte. I therefore compare the aesthetic function of bondage in Buzzati's paintings to the narrative function of the masochistic scene in Pier Vittorio Tondelli's Camere Separate.

    Full Text Available The appearance of musicology as a science is due yo Guido Adler’s foundation act of 1885. The dialectical formulation of musicology as an interaction between systematic and historical disciplines were to confer it sufficien methodological force so that the newly invented science could become practicable as soon as possible. Historically being a descendant of the German historical method (Leopold von Ranke and the one contemporary with positivism (Auguste Comte, musicology affirms itself quickly as an academic discipline (begun by Wilhelm von Humboldt and takes in both sociology (Max Weber and hermeneutics (Hermann Kretzschmar as constituent disciplines. In one sense, musicology presented itself as an open conceptual system, permeable to the evolutionary changes of the thinking field and musical practices and, in a second sense, the methodology of systematic conceptual organization was oriented towards the university teaching field as an offer for pedagogical and research activities. In our text, we propose a hipothesis of approaching the conceptual system of musicology as a cosubstantional system of botn the constituent parts — the systematic and the historical ones, in such a way motivating and explaining its dialectical-evolutionary nature.

  8. A Balkan-style French revolution?: The 1804 Serbian Uprising in European perspective

    Directory of Open Access Journals (Sweden)

    Bataković Dušan T.


    Full Text Available The Serbian uprising of 1804-13, initially a peasant rebellion against abuses of power by local janissaries, turned into a national and social revolution from 1806. During its second phase (late 1806 - early 1807, Serbian insurgents openly proclaimed their demand for independence. Encouraged by their military achievements, the insurgent leaders began to seek wider Balkan support for their struggle against Ottoman domination. Although its political claims were a mixture of modern national and romantic historic rights, the uprising gave hope to all Balkan Christians that the Ottoman defeat was an achievable goal. For the Balkan nations it was a French Revolution adapted to local conditions: the principle of popular sovereignty was opposed to the principle of legitimism; a new peasant-dominated society was created in which, due to the lack of the aristocracy and well-established middle classes, agrarian egalitarianism was combined with the rising aspirations of a modern nation. Its long-term effects on the political and social landscape of the whole region justified the assessment of the eminent German historian Leopold von Ranke who described the uprising, by analogy with the French example, as the Serbian Revolution.

  9. Climate Literacy Ambassadors (United States)

    Ackerman, S. A.; Mooney, M. E.


    The Climate Literacy Ambassadors program is a collaborative effort to advance climate literacy led by the Cooperative Institute of Meteorological Satellite Studies (CIMSS) at the University of Wisconsin-Madison. With support from NASA, CIMSS is coordinating a three-tiered program to train G6-12 teachers to be Ambassadors of Climate Literacy in their schools and communities. The complete training involves participation at a teacher workshop combined with web-based professional development content around Global and Regional Climate Change. The on-line course utilizes e-learning technology to clarify graphs and concepts from the 2007 Intergovernmental Panel on Climate Change Summary for Policy Makers with content intricately linked to the Climate Literacy: The Essential Principles of Climate Science. Educators who take the course for credit can develop lesson plans or opt for a project of their choosing. This session will showcase select lesson plans and projects, ranging from a district-wide action plan that engaged dozens of teachers to Ambassadors volunteering at the Aldo Leopold Climate Change Nature Center to a teacher who tested a GLOBE Student Climate Research Campaign (SCRC) learning project with plans to participate in the SCRC program. Along with sharing successes from the CIMSS Climate Literacy Ambassadors project, we will share lessons learned related to the challenges of sustaining on-line virtual educator communities.

  10. Confessions of a Communications Junkie: Cliff Notes From the Science-Practice Interface (United States)

    Moser, S. C.


    Graduate education in the sciences is - among other things - about learning a foreign language. Proficiency in disciplinary jargon and a strange sort of eloquence in speaking English without being understood by anyone outside one's small 'country of expertise' are among the requirements for entry into academe. Until very recently, the ability to translate one's quirky knowledge back into common language was not part of entraining scientists. Yet, increasingly, the interested public, policy-makers and resource managers, not to speak of science funders, demand that scientists illustrate that their science has societal relevance. Moreover, the urgency of several complex societal and environmental problems puts the onus on scientists to work with experts in other disciplines. This means that the ability to communicate effectively with those outside one's own disciplinary home is rapidly becoming an essential qualification of a 'good' scientist. My own journey from a disciplinary boundary crosser, to hobby communicator, to professional translator of science into English, to alumnae of various media trainings and Aldo Leopold Leadership Fellow, to researcher of the science-practice interface and expert in communication for social change will form the basis of this talk. It weaves together personal experience with scientific insights on why scientists should, why many don't, and how they could interact more effectively with members of a 'different tribe.'

  11. Die Musik der Wiener Klassiker im öffentlichen Bewusstsein und im Blick der Wissenschaft: ein gegenseitiges Missverständnis?

    Manfred Hermann Schmid


    Full Text Available Bildung setzt ein Geschichtsverständnis voraus. Kein Sprachunterricht ohne Spuren von Geschichte, auch kein Religionsunterricht und kein Musikunterricht. Doch Ge­schichte ist entgegen dem schönen Wort von Leopold von Ranke nichts Objektives, schon gar nicht, wenn es um Urteile geht. Sie ist bekanntlich ein intellektuelles Konstrukt. An der Schaf­fung dieses Konstrukts und auch an der Weitergabe, der „trasmissione del sapere musi­cale“, sind ganz verschiedene Instanzen beteiligt – keineswegs nur die Wissenschaft. Im Fall der Musikgeschichte müssen wir mit drei unterschiedlichen Instanzen rechnen: (a der musikalischen Zunft und ihrer Mündlichkeit; (b der Wissenschaft in ihren Publikationen und ihrem akademischen Unterricht; (c der Öffentlichkeit, gesteuert von den Medien.Zwischen (b und (c gibt es noch die Schule. Sie leitet sich in ihrem Selbstverständnis von der Wissenschaft her, ist aber in ungleich höherem Maße als diese mit der öffent­lichen Meinung konfrontiert. Die Geschichtsbilder differieren, wie zu erwarten, und sie differieren auch zu ver­schiedenen Zeiten, wenn ich das punktuell mit den Wiener Klassikern an einem Parade­fall von Kanonbildung und teleologischer Geschichtsschreibung überprüfe.

  13. Assessing Emergency Preparedness and Response Capacity Using Community Assessment for Public Health Emergency Response Methodology: Portsmouth, Virginia, 2013. (United States)

    Kurkjian, Katie M; Winz, Michelle; Yang, Jun; Corvese, Kate; Colón, Ana; Levine, Seth J; Mullen, Jessica; Ruth, Donna; Anson-Dwamena, Rexford; Bayleyegn, Tesfaye; Chang, David S


    For the past decade, emergency preparedness campaigns have encouraged households to meet preparedness metrics, such as having a household evacuation plan and emergency supplies of food, water, and medication. To estimate current household preparedness levels and to enhance disaster response planning, the Virginia Department of Health with remote technical assistance from the Centers for Disease Control and Prevention conducted a community health assessment in 2013 in Portsmouth, Virginia. Using the Community Assessment for Public Health Emergency Response (CASPER) methodology with 2-stage cluster sampling, we randomly selected 210 households for in-person interviews. Households were questioned about emergency planning and supplies, information sources during emergencies, and chronic health conditions. Interview teams completed 180 interviews (86%). Interviews revealed that 70% of households had an emergency evacuation plan, 67% had a 3-day supply of water for each member, and 77% had a first aid kit. Most households (65%) reported that the television was the primary source of information during an emergency. Heart disease (54%) and obesity (40%) were the most frequently reported chronic conditions. The Virginia Department of Health identified important gaps in local household preparedness. Data from the assessment have been used to inform community health partners, enhance disaster response planning, set community health priorities, and influence Portsmouth's Community Health Improvement Plan.

  14. VEGAS: VErsatile GBT Astronomical Spectrometer (United States)

    Bussa, Srikanth; VEGAS Development Team


    The National Science Foundation Advanced Technologies and Instrumentation (NSF-ATI) program is funding a new spectrometer backend for the Green Bank Telescope (GBT). This spectrometer is being built by the CICADA collaboration - collaboration between the National Radio Astronomy Observatory (NRAO) and the Center for Astronomy Signal Processing and Electronics Research (CASPER) at the University of California Berkeley.The backend is named as VErsatile GBT Astronomical Spectrometer (VEGAS) and will replace the capabilities of the existing spectrometers. This backend supports data processing from focal plane array systems. The spectrometer will be capable of processing up to 1.25 GHz bandwidth from 8 dual polarized beams or a bandwidth up to 10 GHz from a dual polarized beam.The spectrometer will be using 8-bit analog to digital converters (ADC), which gives a better dynamic range than existing GBT spectrometers. There will be 8 tunable digital sub-bands within the 1.25 GHz bandwidth, which will enhance the capability of simultaneous observation of multiple spectral transitions. The maximum spectral dump rate to disk will be about 0.5 msec. The vastly enhanced backend capabilities will support several science projects with the GBT. The projects include mapping temperature and density structure of molecular clouds; searches for organic molecules in the interstellar medium; determination of the fundamental constants of our evolving Universe; red-shifted spectral features from galaxies across cosmic time and survey for pulsars in the extreme gravitational environment of the Galactic Center.

  15. Development of the ECODAB into a relational database for Escherichia coli O-antigens and other bacterial polysaccharides. (United States)

    Rojas-Macias, Miguel A; Ståhle, Jonas; Lütteke, Thomas; Widmalm, Göran


    Escherichia coli O-antigen database (ECODAB) is a web-based application to support the collection of E. coli O-antigen structures, polymerase and flippase amino acid sequences, NMR chemical shift data of O-antigens as well as information on glycosyltransferases (GTs) involved in the assembly of O-antigen polysaccharides. The database content has been compiled from scientific literature. Furthermore, the system has evolved from being a repository to one that can be used for generating novel data on its own. GT specificity is suggested through sequence comparison with GTs whose function is known. The migration of ECODAB to a relational database has allowed the automation of all processes to update, retrieve and present information, thereby, endowing the system with greater flexibility and improved overall performance. ECODAB is freely available at Currently, data on 169 E. coli unique O-antigen entries and 338 GTs is covered. Moreover, the scope of the database has been extended so that polysaccharide structure and related information from other bacteria subsequently can be added, for example, from Streptococcus pneumoniae. © The Author 2014.

  16. Summary of the engineering assessment of inactive uranium mill tailings, Spook Site, Converse County, Wyoming

    International Nuclear Information System (INIS)


    Ford, Bacon, Davis Utah Inc. has reevaluated the Spook site in order to revise the December 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings 48 mi northeast of Casper, in Converse County, Wyoming. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 187,000 tons of tailings at the Spook site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors. The four alternative actions presented in this engineering assessment range from millsite decontamination with the addition of 3 m of stabilization cover materI), to rema densitometers for measuring cross-sectionally averaged mass velocity in steady steam-water flow are presented. The results are interpreted ntation

    The prevalence of diagnosed celiac disease is celiac disease and the utility of screening in the general adult population of a geographically isolated area. Serum tissue transglutaminase antibodies (tTG-IgA) were measured in volunteer health-care participants aged ≥ 18 years at the annual Casper, Wyoming, Blue Envelope Health Fair blood draw. Subjects with positive tTG-IgA tests had their endomysial IgA antibodies checked. Double positives were offered endoscopy with small bowel biopsy. All subjects completed a short gastrointestinal (GI) symptom questionnaire. A total of 3,850 residents of the Natrona County had serologic evaluation for celiac disease, 34 of whom tested positive for both tTG and endomysial antibody (EMA) IgA. Excluding three individuals with previous diagnosis of celiac disease, the overall prevalence of positive celiac serology in this community sample was 0.8%. All 31 subjects were offered a small bowel biopsy. Of the 18 biopsied subjects, 17 (94%) had at least partial villous atrophy. Symptoms that were reported by the fair attendees did not predict positivity. Screening for celiac disease was widely accepted in this preventative health-care setting. Undiagnosed celiac disease affects 1 in 126 individuals in this Wyoming community. Most were asymptomatic or had atypical presentations. Serologic testing can readily detect this disease in a general population.

    The U.S. Geological Survey (USGS), in cooperation with the State Office, Reservoir Management Group (RMG), of the Bureau of Land Management (BLM) in Casper (Wyoming), investigated the coalbed methane resources (CBM) in the Powder River Basin, Wyoming and Montana, from 1999 to the present. Beginning in late 1999, the study also included the Williston Basin in Montana and North and South Dakota and Green River Basin and Big Horn Basin in Wyoming. The rapid development of CBM (referred to as coalbed natural gas by the BLM) during the early 1990s, and the lack of sufficient data for the BLM to fully assess and manage the resource in the Powder River Basin, in particular, gave impetus to the cooperative program. An integral part of the joint USGS-BLM project was the participation of 25 gas operators that entered individually into confidential agreements with the USGS, and whose cooperation was essential to the study. The arrangements were for the gas operators to drill and core coal-bed reservoirs at their cost, and for the USGS and BLM personnel to then desorb, analyze, and interpret the coal data with joint funding by the two agencies. Upon completion of analyses by the USGS, the data were to be shared with both the BLM and the gas operator that supplied the core, and then to be released or published 1 yr after the report was submitted to the operator.

  19. Analysis of Fluctuations of Electron Density in the D-region During the 2017 Solar Eclipse using a Very Low Frequency Receiver (United States)

    Hernandez, E.; Mathur, S.; Fenton, A.; Behrend, C. C.; Bering, E., III


    As part of the Undergraduate Student Instrumentation Project (USIP) at the University of Houston, multiple Very Low Frequency (VLF) Radio Receivers will be set up during the 2017 solar eclipse. They will be taking data from Omaha, Nebraska and Casper, Wyoming. The receiver, using an air loop antenna, will record magnetic field fluctuations caused by VLF waves. The purpose of this experiment is to study the effects of the sudden change in electromagnetic radiation from the sun on the D-region of the ionosphere. VLF waves were chosen for measurement because naturally occurring VLF waves propagate through the Earth-ionosphere waveguide, which can be used to remotely observe the ionosphere. The D-region reduces the energy in propagating waves due to absorption. This means that any fluctuations in the D-region are inversely correlated to the strength of VLF waves being received. The experiment will focus on receiving waves transmitted from specific stations that are on the other side of totality. The amplitude and phase of the received waves will be measured and analyzed. It is hoped that this experiment will help us gain a better understanding of VLFs from the D-region during the solar eclipse, as well as increasing the overall data available for use by the community.

CONCLUSIONS/SIGNIFICANCE: During 2005-2007, 162 cases of ST5 IPD and 45 cases of ST8 IPD were identified. The isolates demonstrated phenotypic and genotypic clonality. The ST5 isolates were sequence type (ST 289 and demonstrated intermediate susceptibility to TMP-SMX. The ST8 isolates were predominantly ST1268, with a susceptible antimicrobial susceptibility profile. Individuals with ST5 IPD were more likely to be middle aged (OR 2.6, homeless (OR 4.4, using illicit drugs(OR 4.8, and asthmatic(OR 2.6. Those with ST8 were more likely to be male (OR 4.4, homeless (OR 2.6, aboriginal (OR7.3, and a current smoker (OR 2.5. Overlapping outbreaks of ST5 and ST8 IPD occurred in an open community in Calgary, Canada and homelessness was a predominant risk factor. Homelessness represents a unique community in which pneumococcal outbreaks can occur.

  1. Successful Replacement of Artemia salina nauplii with Marine Rotifers (Brachionus plicatilis) in the Diet of Preadult Zebrafish (Danio rerio). (United States)

    Lawrence, Christian; James, Althea; Mobley, Scottie


    Previously established rearing protocols for zebrafish begin feeding with marine rotifers (Brachionus plicatilis), followed by Artemia nauplii until the fish reach subadult stage, the developmental time point at which they can be most easily transitioned onto a processed diet. However, the inclusion of Artemia is less than ideal, given its fluctuating availability and high costs. We tested whether or not we could replace Artemia with rotifers during our normal rearing sequence and still meet published performance standards for (i) weaning fish onto a processed diet by 25 days postfertilization (dpf) and (ii) successful breeding by 60 dpf. Here, we present the results of trials where wild-type and casper zebrafish were fed exclusively with rotifers (R) or rotifers followed by Artemia (RA) for the first 25 dpf after which point all fish were transitioned to a processed diet (Gemma Micro 300). We measured growth and survival at days 25 and 60, and tested for reproductive capability at 60 dpf. While growth performance was significantly better in the RA groups, we were still able to meet goals for both weaning and generation time in the R groups without compromising survival or sex ratios.

    Full Text Available A relatively new technique for measuring the electron cloud density in storage rings has been developed and successfully demonstrated [S. De Santis, J. M. Byrd, F. Caspers, A. Krasnykh, T. Kroyer, M. T. F. Pivi, and K. G. Sonnad, Phys. Rev. Lett. 100, 094801 (2008.PRLTAO0031-900710.1103/PhysRevLett.100.094801]. We present the experimental results of a systematic application of this technique at the Cornell Electron Storage Ring Test Accelerator. The technique is based on the phase modulation of the TE mode transmitted in a synchrotron beam pipe caused by the periodic variation of the density of electron plasma. Because of the relatively simple hardware requirements, this method has become increasingly popular and has been since successfully implemented in several machines. While the principles of this technique are straightforward, quantitative derivation of the electron cloud density from the measurement requires consideration of several effects, which we address in detail.

  4. Review of nuclear air treatment system related License Event Reports for the period 1985 - 1987

    Jacox, J.W.


    This paper will continue the review of HVAC/NATS related LERS presented at past Air Cleaning Conferences by Dr. D. W. Moeller and his associates. The general approach and format are similar. LER abstracts from mid 1985 through 1987 were reviewed and those related to HVAC/NATS classified and analyzed. The categories were jointly developed by Dr. Moeller, Dr. Casper Sun and myself. In appropriate cases both primary and secondary categories fora problem are given. A basic listing by category and brief statistical review are presented. Additionally a number of categories are discussed in some detail. The categories chosen for specific review are intended to highlight particular problem areas. NUREG/CR-2000 License Event Report (LER) Compilation is the basis for the initial review and coding. In essentially all cases where an LER is classified as of interest the complete LER was obtained and reviewed in full. The intent of this paper is to provide a basis for the industry to document and analyze problem areas that require additional attention. It appears that about 15% of all LERS in the subject period are HVAC/NATS related. This figure is generally consistent with those reported at the 17th DOE Nuclear Air Cleaning Conference. It is hoped that such attention will allow additional resources to be allocated to upgrade systems, procedures and training as well as in some cases government regulation

    Douglas, K. A.; Anderson, D. P.; Bankay, R.; Chen, H.; Cobb, J.; Korpela, E. J.; Lebofsky, M.; Parsons, A.; von Korff, J.; Werthimer, D.


    Our group contributes to the Search for Extra-Terrestrial Intelligence (SETI) by developing and using world-class signal processing computers to analyze data collected on the Arecibo telescope. Although no patterned signal of extra-terrestrial origin has yet been detected, and the immediate prospects for making such a detection are highly uncertain, the SETI@home project has nonetheless proven the value of pursuing such research through its impact on the fields of distributed computing, real-time signal processing, and radio astronomy. The SETI@home project has spun off the Center for Astronomy Signal Processing and Electronics Research (CASPER) and the Berkeley Open Infrastructure for Networked Computing (BOINC), both of which are responsible for catalyzing a smorgasbord of new research in scientific disciplines in countries around the world. Futhermore, the data collected and archived for the SETI@home project is proving valuable in data-mining experiments for mapping neutral galatic hydrogen and for detecting black-hole evaporation.

  6. Engineering assessment of inactive uranium mill tailings, Spook site, Converse County, Wyoming

    International Nuclear Information System (INIS)


    Ford, Bacon and Davis Utah Inc. has reevaluated the Spook site in order to revise the December 1977 engineering assessment of the problems resulting from the existence of radioactive uranium mill tailings 48 mi northeast of Casper, in Converse County, Wyoming. This engineering assessment has included the preparation of topographic maps, the performance of core drillings and radiometric measurements sufficient to determine areas and volumes of tailings and radiation exposures of individuals and nearby populations, the investigations of site hydrology and meteorology, and the evaluation and costing of alternative corrective actions. Radon gas released from the 187,000 tons of tailings at the Spook site constitutes the most significant environmental impact, although windblown tailings and external gamma radiation also are factors.

  7. Continuous miner and friction bolts play key roles in Highland's move underground

    International Nuclear Information System (INIS)

    Scott, J.J.; Jackson, D.


    Exxon has added underground mining operations to the open pits at its Highland uranium mine and mill complex 60 mi northeast of Casper in the Powder River Basin and has, in the process, adopted some innovative mining techniques. A continuous shield miner is being used in conjunction with continuous ground support--thought to be the first truly successful combination of these techniques in a US uranium mine. Highland miners are also making extensive use of ''Split Sets,'' a patented friction rock bolt system invented in 1973, which has proven to be a successful cost-saving substitute for timber supports in Highland's soft, water-saturated, extremely unstable sediments. Initial mine production at Highland began in July 1972, and the mill started up the following October. Design capacity at startup was 2,000 tpd, a figure that has since been expanded to 3,000 tpd through mill modifications but without a major construction program. Current production is about 2 million lb per year of U 3 O 8

    International Nuclear Information System (INIS)


    After an assessment of concerns, alternatives, and the addition of license conditions as discussed below, the proposed action is the issuance of a Source and Byproduct Material License to Conoco, Inc. In July 1980, Conoco applied to the NRC for an NRC Source and Byproduct Material License to construct and operate in Cambell County, Wyoming, a uranium mill, associated with an open-pit mine, with an annual U 3 O 8 production rate of 715 MT (788 tons) per year. The proposed project would be located on 1604 ha (3963-acre) site approximately midway between Casper and Gillette and would lie about 0.8 km (0.5 mile) south of State Highway 387. The applicant proposes to receive and process ore from the Moore Ranch mine, which is located within the permit boundary. Other potential sources of ore include other Conoco mines, toll-milling customers, and joint venture partners in the immediate vicinity. A conventional sulfuric acid leach, countercurrent decantation (CCD), solvent extraction, ammonia precipitation circuit will be used to extract and concentrate the U 3 O 8 contained in the ore. Conoco proposes to operate 24 hours a day, 330 days a year, over the anticipated operating life of the mill (11.5 years). The total life of the mill--mine project is expected to be 17 to 18 years, including construction, operation and reclamation. 31 figs., 74 tabs

    Yadav, Rajesh; Somashekar, Dundaiah; Sodha, Samir V; Laserson, Kayla F; Venkatesh, Srinivasa; Chauhan, Himanshu


    Torrential rainfall and flooding from September 2-6, 2014 submerged >350 villages in Jammu and Kashmir state. We conducted rapid needs assessment in capital Srinagar from 27 September to 1 October to assess population health and safety needs. Based on Community Assessment for Public Health Emergency Response (CASPER) methodology, we selected 7 households each from 30 census blocks using 2-stage cluster sampling. We collected information on demographics, needs, and illnesses using structured questionnaire. Of the 210 households surveyed, an estimated 57% (CI: 41%-73%) reported significant damage, 50% (CI: 36%-63%) were evacuated, and 16% (CI: 10%-22%) reported injuries. Households lacked electricity (22%; CI: 8.8%-36%), tap water (13%; CI: 5%-21%), working toilets (11%; CI: 4%-19%), and adequate food supply (14%; CI: 8%-20%). Moreover, 55% (CI: 45%-64%) of households reported cough, cold, fever, rashes, or diarrhea; 68% (CI: 59%-77%) experienced agitation, anxiety, depression, or nightmares since the flooding. Of the households with a member on medicines for non-communicable diseases, 40% did not have a week's supply. Restoring basic essentials (30%; CI: 22%-37%) and repairing houses (30%; CI: 19%-40%) were the most urgent needs expressed. Floods damaged >1/2 of households in Srinagar, disrupting basic essentials, and causing mental trauma. These findings helped authorities prioritize assistance with psychological symptoms and availability of prescription medicines. (Disaster Med Public Health Preparedness. 2018;page 1 of 5).

    We present early science results from MUSTANG-2, a 90 GHz feedhorn-coupled, microwave SQUID-multiplexed TES bolometer array operating on the Robert C. Byrd Green Bank Telescope (GBT). The feedhorn and waveguide-probe-coupled detector technology is a mature technology, which has been used on instruments such as the South Pole Telescope, the Atacama Cosmology Telescope, and the Atacama B-mode Search telescope. The microwave SQUID multiplexer-based readout system developed for MUSTANG-2 currently reads out 66 detectors with a single coaxial cable and will eventually allow thousands of detectors to be multiplexed. This microwave SQUID multiplexer combines the proven abilities of millimeter wave TES detectors with the multiplexing capabilities of KIDs with no degradation in noise performance of the detectors. Each multiplexing device is read out using warm electronics consisting of a commercially available ROACH board, a DAC/ADC card, and an Intermediate Frequency mixer circuit. The hardware was originally developed by the Collaboration for Astronomy Signal Processing and Electronic Research (CASPER) group, whose primary goal is to develop scalable FPGA-based hardware with the flexibility to be used in a wide range of radio signal processing applications. MUSTANG-2 is the first on-sky instrument to use microwave SQUID multiplexing and is available as a shared-risk/PI instrument on the GBT. In MUSTANG-2’s first season 7 separate proposals were awarded a total of 230 hours of telescope time.

  12. Case report: Time of death estimation of a buried body by modeling a decomposition matrix for a pig carcass. (United States)

    Niederegger, Senta; Schermer, Julia; Höfig, Juliane; Mall, Gita


    Estimating time of death of buried human bodies is a very difficult task. Casper's rule from 1860 is still widely used which illustrates the lack of suitable methods. In this case study excavations in an arbor revealed the crouching body of a human being, dressed only in boxer shorts and socks. Witnesses were not able to generate a concise answer as to when the person in question was last seen alive; the pieces of information opened a window of 2-6 weeks for the possible time of death. To determine the post mortem interval (PMI) an experiment using a pig carcass was conducted to set up a decomposition matrix. Fitting the autopsy findings of the victim into the decomposition matrix yielded a time of death estimation of 2-3 weeks. This time frame was later confirmed by a new witness. The authors feel confident that a widespread conduction of decomposition matrices using pig carcasses can lead to a great increase of experience and knowledge in PMI estimation of buried bodies and will eventually lead to applicable new methods.

  13. Experimental weed control of Najas marina ssp. intermedia and Elodea nuttallii in lakes using biodegradable jute matting

    Markus A. Hoffmann


    Full Text Available The use of jute matting in managing the invasive aquatic macrophyte species Elodea nuttallii (Planch. H. St. John and Najas marina ssp. intermedia (Wolfg. ex Gorski Casper (Najas intermedia was studied in laboratory experiments and field trials. Four German lakes with predominant population of Najas intermedia or Elodea nuttalli were chosen for the experiment and areas between 150 and 300 m² were covered with jute textile. The effect of the matting on the growth of invasive and non-invasive macrophytes was determined through comparison with control transects. Biodegradable jute matting successfully suppressed the invasive macrophyte Najas intermedia and significantly reduced the growth of Elodea nuttalli in lakes. The results indicate that the capability of the matting to inhibit the growth of Elodea nuttallii and Najas intermedia depends on the mesh size of the jute weaving and that environmental conditions can affect its efficiency. Various indigenous species like Charales or Potamogeton pusillus L. were able to grow through the jute fabric and populate the treated areas. Until the end of the vegetation period, none of the invasive species were able to penetrate the covering and establish a stable population; in fact, in the subsequent year the jute matting affected only the spread of Najas intermedia. Jute matting proved to be an easy-to-use and cheap method to control the growth of Elodea nuttallii and Najas intermedia.

  15. Auerbach e lo Storicismo tedesco

    Directory of Open Access Journals (Sweden)

    Guido Lucchini


    Full Text Available Il saggio esamina i rapporti tra l’opera di Erich Auerbach e la cultura tedesca del tempo. In particolare tenta di ricostruire la fitta trama di relazioni esistenti, anche a livello personale. Infatti Auerbach a Berlino aveva studiato non solo con i filologi romanzi Erhard Lommatzsch e Max Leopold Wagner, ma anche col filosofo Ernst Troeltsch e con lo storico Friedrich Meinecke. Nella vasta bibliografia sul romanista non mancano ormai i lavori, fin da quello pionieristico di Dante Della Terza, su questo aspetto della sua formazione accademica. Ma essi sono perlopiù circoscritti al periodo giovanile (traduzione della Scienza nuova e della monografia crociana su Vico, lasciando in ombra l’eredità dello storicismo tedesco. A quest’ultimo, sia dal punto di vista terminologico che da quello concettuale, rivolge l’attenzione il presente saggio che cerca di documentare puntualmente l’influenza di Dilthey, genericamente nota e sostenuta da più studiosi, ma senza osservazioni circostanziate. Essa va ben oltre gli anni venti e si può rintracciare anche nell’opera della maturità di Auerbach più famosa, Mimesis. Come pure non meno essenziale sembra il rapporto col Meinecke delle Origini dello storicismo, che si configura però come uno scambio reciproco d’influssi. Più problematico è da accertare sul piano strettamente documentale quello con Cassirer, probabilmente mediato da Panofsky. La contestualizzazione del retroterra culturale di Mimesis è completata da una ricognizione delle prime recensioni dell’opera e, per quanto l’Italia, anche dall’esame del fascicolo di Auerbach conservato nell’archivio Einaudi. The essay considers the relationship between Erich Auerbach and the German culture of the time. In particular, it attempts to reconstruct the dense web of relationships, even on a personal level. Auerbach indeed in Berlin had studied not only with the romance philologists Erhard Lommatzsch and Max Leopold Wagner, but also

  17. Recent Photocatalytic Applications for Air Purification in Belgium

    Directory of Open Access Journals (Sweden)

    Elia Boonen


    Full Text Available Photocatalytic concrete constitutes a promising technique to reduce a number of air contaminants such as NOx and VOC’s, especially at sites with a high level of pollution: highly trafficked canyon streets, road tunnels, the urban environment, etc. Ideally, the photocatalyst, titanium dioxide, is introduced in the top layer of the concrete pavement for best results. In addition, the combination of TiO2 with cement-based products offers some synergistic advantages, as the reaction products can be adsorbed at the surface and subsequently be washed away by rain. A first application has been studied by the Belgian Road Research Center (BRRC on the side roads of a main entrance axis in Antwerp with the installation of 10.000 m² of photocatalytic concrete paving blocks. For now however, the translation of laboratory testing towards results in situ remains critical of demonstrating the effectiveness in large scale applications. Moreover, the durability of the air cleaning characteristic with time remains challenging for application in concrete roads. From this perspective, several new trial applications have been initiated in Belgium in recent years to assess the “real life” behavior, including a field site set up in the Leopold II tunnel of Brussels and the construction of new photocatalytic pavements on industrial zones in the cities of Wijnegem and Lier (province of Antwerp. This paper first gives a short overview of the photocatalytic principle applied in concrete, to continue with some main results of the laboratory research recognizing the important parameters that come into play. In addition, some of the methods and results, obtained for the existing application in Antwerp (2005 and during the implementation of the new realizations in Wijnegem and Lier (2010–2012 and in Brussels (2011–2013, will be presented.

  18. Lava and Life: New investigations into the Carson Volcanics, lower Kimberley Basin, north Western Australia (United States)

    Orth, Karin; Phillips, Chris; Hollis, Julie


    The Carson Volcanics are the only volcanic unit in the Paleoproterozoic Kimberley Basin and are part of a poorly studied Large Igneous Province (LIP) that was active at 1790 Ma. New work focussing on this LIP in 2012 and 2013 involved helicopter-supported traverses and sampling of the Carson Volcanics in remote areas near Kalumburu in far north Western Australia's Kimberley region. The succession is widespread and flat lying to gently dipping. It consists of three to six basalt units with intercalated sandstone and siltstone. The basalts are 20-40 m thick, but can be traced up to 60 km along strike. The basalt can be massive or amygdaloidal and commonly display polygonal to subhorizontal and rare vertical columnar jointing. Features of the basalt include ropy lava tops and basal pipe vesicles consistent with pahoehoe lavas. The intercalated cross-bedded quartzofeldspathic sandstone and siltstone vary in thickness up to 40 m and can be traced up to 40 km along strike. Peperite is common and indicates interaction between wet, unconsolidated sediment and hot lava. Stromatolitic chert at the top of the formation represents the oldest life found within the Kimberley region. Mud cracks evident in the sedimentary rocks, and stromatolites suggest an emergent broad tidal flat environment. The volcanics were extruded onto a wide marginal margin setting subject to frequent flooding events. Thickening of the volcanic succession south and the palaeocurrents in the underlying King Leopold Sandstone and the overlying Warton Sandstone suggest that this shelf sloped to the south. The type of basalt and the basalt morphology indicate a low slope gradient of about 1°.

  19. Geomorphic changes resulting from floods in reconfigured gravel-bed river channels in Colorado, USA (United States)

    Elliott, J.G.; Capesius, J.P.


    Geomorphic changes in reconfi gured reaches of three Colorado rivers in response to floods in 2005 provide a benchmark for "restoration" assessment. Sedimententrainment potential is expressed as the ratio of the shear stress from the 2 yr, 5 yr, 10 yr, and 2005 floods to the critical shear stress for sediment. Some observed response was explained by the excess of flood shear stress relative to the resisting force of the sediment. Bed-load entrainment in the Uncompahgre River and the North Fork Gunnison River, during 4 and 6 yr floods respectively, resulted in streambed scour, streambed deposition, lateral-bar accretion, and channel migration at various locations. Some constructed boulder and log structures failed because of high rates of bank erosion or bed-material deposition. The Lake Fork showed little or no net change after the 2005 flood; however, this channel had not conveyed floods greater than the 2.5 yr flood since reconfi guration. Channel slope and the 2 yr flood, a surrogate for bankfull discharge, from all three reconfi gured reaches plotted above the Leopold and Wolman channel-pattern threshold in the "braided channel" region, indicating that braiding, rather than a single-thread meandering channel, and midchannel bar formation may be the natural tendency of these gravel-bed reaches. When plotted against a total stream-power and median-sediment-size threshold for the 2 yr flood, however, the Lake Fork plotted in the "single-thread channel" region, the North Fork Gunnison plotted in the " multiplethread" region, and the Uncompahgre River plotted on the threshold. All three rivers plotted in the multiple-thread region for floods of 5 yr recurrence or greater. ?? 2009 Geological Society of America.

    Full Text Available In the southern escarpment of the Serra da Mantiqueira, northeast geographic divider between the State of São Paulo and Minas Gerais, there was an environmental accident caused by the disruption of an adductor whose purpose is to lead the water from a reservoir located at an altitude of 1820 m to the machine house where there is an electric generator located at 750 m. This accident resulted in the formation of a scar on the hillside forest, with removal of soil and vegetation. To reverse the erosion processes, a methodology was developed consisting of the use of four barriers (numbered I to IV formed by seedlings of Bambusa mutiplex (Lour., whose purpose was to divert the water runoff in order to provide the regeneration of native vegetation. Stalks of bamboo intercropped with Bambusa multiplex were used to contain debris in two gullies formed by erosion. The development of vegetation was monitored for 18 months and evaluated by the application of a Leopold Matrix composed of 5 points, which are: erosion, regeneration of vegetation, success of bamboo planting, installed conservation structures and functionality. The purpose of the matrix was to demonstrate the effectiveness of interventions using bamboo. The result of the classification matrix enabled the quantitative and qualitative classification of the interventions, resulting in five levels, where the barriers I, II and IV were considered to be of very high efficiency, and barrier III was considered to be of high efficiency. The contention of the gully was considered to be of medium to very high efficiency.

  2. Violin Pedagogy and the Physics of the Bowed String (United States)

    McLeod, Alexander Rhodes

    The paper describes the mechanics of violin tone production using non-specialist language, in order to present a scientific understanding of tone production accessible to a broad readership. As well as offering an objective understanding of tone production, this model provides a powerful tool for analyzing the technique of string playing. The interaction between the bow and the string is quite complex. Literature reviewed for this study reveals that scientific investigations have provided important insights into the mechanics of string playing, offering explanations for factors which both contribute to and limit the range of tone colours and dynamics that stringed instruments can produce. Also examined in the literature review are significant works of twentieth century violin pedagogy exploring tone production on the violin, based on the practical experience of generations of teachers and performers. Hermann von Helmholtz described the stick-slip cycle which drives the string in 1863, which replaced earlier ideas about the vibration of violin strings. Later, scientists such as John Schelleng and Lothar Cremer were able to demonstrate how the mechanics of the bow-string interaction can create different tone colours. Recent research by Anders Askenfelt, Knut Guettler, and Erwin Schoonderwaldt have continued to refine earlier research in this area. The writings of Lucien Capet, Leopold Auer, Carl Flesch, Paul Rolland, Kato Havas, Ivan Galamian, and Simon Fischer are examined and analyzed. Each author describes a different approach to tone production on the violin, representing a different understanding of the underlying mechanism. Analyzing these writings within the context of a scientific understanding of tone production makes it possible to compare these approaches more consistently, and to synthesize different concepts drawn from the diverse sources evaluated.

    Full Text Available La minería de oro es una actividad que se ha desarrollado por siglos en diferentes territorios en el planeta. Sin embargo, la minería ha generado impactos ambientales afectando a la sociedad, debido a que comprometen la cantidad y calidad de los servicios ecosistémicos y en consecuencia, la calidad de vida de la población mundial. Para medir el nivel de afectación sobre los componentes del ambiente, se revisaron los métodos clásicos para Estudios de Impacto Ambiental (EIA para proyectos mineros y se tomó como base la matriz de Leopold desarrollada por el Servicio Geológico del Departamento del Interior de los Estados Unidos, para valorizar los impactos de actividades mineras. En esta investigación se revisaron investigaciones publicadas con las palabras clave “matriz cualitativa” y “minería de oro”, tanto en inglés como en español, desde el año 2000 al 2011, en proyectos mineros realizados en países en vía de desarrollo. Posteriormente, se extrajeron y sistematizaron, las metodologías clásicas y sus variaciones y los componentes ecológicos y actividades del proyecto comunes en los estudios. Las metodologías usadas fueron cualitativas. Adicionalmente, se desarrolló la metodología Valor del Índice Ambiental (VIA para valorizar los impactos ecológicos de la minería de oro en la cuenca del río Guabas, Valle del Cauca, Colombia. Se encontró que el impacto promedio de la actividad minera desarrollada en el río Guabas fue considerado severo, a diferencia del impacto global revisado en la literatura, que fue considerado como moderado, en la mayoría de los casos.

  4. An investigation of the critical components of a land ethic: An application of Q methodology (United States)

    Spradling, Suzanne Shaw

    Scope and method of study. The purpose of this study was to reveal the underlying structure of the beliefs of a sample of environmental educators regarding the critical components of a land or environmental ethic. Participants in the study were 30 environmental educators from seven states. All had been trained in one or more of the following national environmental education programs: Project WILD, Project WET, Project Learning Tree, Leopold Education Project, or Leave No Trace. Ages of the participants ranged from 18--63 years. Q methodology directed the study. Each participant completed a Q-sort of 54 statements related to environmental ethics. The data were analyzed using a computer program PQMethod 2.06. This program performed a correlation matrix as input data for factor analysis, and a VARIMAX rotation. Participant demographic data were collected in order to provide a more complete picture of the revealed structure of beliefs. Findings and conclusions. A three-factor solution was revealed from the analysis of the data. These factors represent the groupings of the participants with like beliefs in reference to the critical components of environmental ethics. Factor one was named Nature's Advocates. These individuals believe in equal rights for all parts of the environment. Factor two was named Nature's Stewards because of the revealed belief that humans were to have dominion over the earth given to them by the creator and that natural resources should be used responsibly. Factor three was named Nature's Romantics because of their belief that nature should be preserved for its aesthetic value and because of their naive approach to conservation. The demographic data added detail to the portrait created from the Q-sort data analysis. It is important then, to take into consideration what environmental educators believe about environmental ethics in designing meaningful curriculum that seeks to foster the development of those ethics. This study reveals the beliefs

  5. De la bioética a la ecoética (Una reflexión desde el «Racionalismo dialéctico»

    Full Text Available La «crisis ambiental», a causa de la novedad, tiene dos características muy importantes. De un lado está el lenguaje en dos perspectivas. En la apreciación de Gastón Bachelard, el problema de la diversidad de conceptualizaciones y teorizaciones al respecto, y del lado de Nicholas Georgescu-Roegen, la carencia de una clara certificación. La “Ética de la Tierra”, escrita por Aldo Leopold fue una primera aproximación a la configuración de un comportamiento ético referido a la problemática ambiental; luego vino la concepción bioética, que por carencia de su certificación, no logró una fundamentación operacional ni teórica adecuada. En este sentido se hace necesario clarificar muy bien el lenguaje para tener una expresión definida sobre esa crisis ambiental, la cual se ubica dentro de una temática que desborda el interés científico y se constituye en una preocupación política a todos los niveles. La otra característica es ser una temática claramente transdisciplinaria, lo que hace necesario avanzar sobre una buena fundamentación operacional y teórica para evitar discusiones sin un objeto claro de trabajo que conduzca a referentes distintos e indistinguibles.

This review consolidates previously published findings from our group in order to compare and contrast the spatial profile of neural activity coherence across these distinct cortical dimensions. We focus on studies of ongoing local field potential (LFP data obtained simultaneously from multiple sites in the primary visual cortex in two types of experiments in which electrode contacts were spaced either along the cortical surface or at different laminar positions. These studies demonstrate that across both dimensions the coherence of ongoing LFP fluctuations diminishes as a function of interelectrode distance, although the nature and spatial scale of this falloff is very different. Along the cortical surface, the overall LFP coherence declines gradually and continuously away from a given position. In contrast, across the cortical layers, LFP coherence is discontinuous and compartmentalized as a function of depth. Specifically, regions of high LFP coherence fall into discrete superficial and deep laminar zones, with an abrupt discontinuity between the granular and infragranular layers. This spatial pattern of ongoing LFP coherence is similar when animals are at rest and when they are engaged in a behavioral task. These results point to the existence of partially segregated laminar zones of cortical processing that extend tangentially within the laminar compartments and are thus oriented orthogonal to the cortical columns. We interpret these electrophysiological observations in light of the known anatomical organization of

    Full Text Available O crescente processo de fragmentação das florestas estacionais semideciduais tem exigido o desenvolvimento de metodologias que possibilitem obter informações ecológicas em um curto período para os remanescentes naturais. A partir de uma adaptação da matriz de interação de Leopold, este estudo buscou avaliar a influência dos impactos antrópicos em dez fragmentos de florestas estacionais semideciduais localizados no Triângulo Mineiro. Foram utilizados levantamentos fitossociológicos prévios da comunidade arbórea. Foram avaliadas a intensidade, frequência e espacialidade dos seguintes impactos: lixo urbano, trilhas, acessibilidade, estradas internas, presença de gado e corte seletivo de madeira. Análises de regressão testaram a influência da matriz de impacto nos parâmetros ecológicos de riqueza, densidade, área basal, classes diamétricas e grupos sucessionais dos fragmentos. A matriz de impactos conseguiu classificar os fragmentos quanto à perturbação antrópica e esteve correlacionada com alguns parâmetros ecológicos destes fragmentos. Nos fragmentos mais perturbados foi observada a redução de indivíduos das últimas classes de diâmetro e das espécies secundárias tardias, além do aumento significativo de espécies pioneiras. Os resultados obtidos demonstraram a influência da perturbação na estrutura e funcionalidade das florestas estudadas e, que esta metodologia pode ser eficiente para obter informação sobre o estado de conservação dos remanescentes vegetais da região.

  8. Sensory memory of illusory depth in structure-from-motion. (United States)

    Pastukhov, Alexander; Lissner, Anna; Füllekrug, Jana; Braun, Jochen


    When multistable displays (stimuli consistent with two or more equally plausible perceptual interpretations) are presented intermittently, their perceptions are stabilized by sensory memory. Independent memory traces are generated not only for different types of multistable displays (Maier, Wilke, Logothetis, & Leopold, Current Biology 13:1076-1085, 2003), but also for different ambiguous features of binocular rivalry (Pearson & Clifford, Journal of Vision 4:196-202, 2004). In the present study, we examined whether a similar independence of sensory memories is observed in structure-from-motion (SFM), a multistable display with two ambiguous properties. In SFM, a 2-D planar motion creates a vivid impression of a rotating 3-D volume. Both the illusory rotation and illusory depth (i.e., how close parts of an object appear to the observer) of an SFM object are ambiguous. We dissociated the sensory memories of these two ambiguous properties by using an intermittent presentation in combination with a forced-ambiguous-switch paradigm (Pastukhov, Vonau, & Braun, PLoS ONE 7:e37734, 2012). We demonstrated that the illusory depth of SFM generates a sensory memory trace that is independent from that of illusory rotation. Despite this independence, the specificities levels of the sensory memories were identical for illusory depth and illusory rotation. The history effect was weakened by a change in the volumetric property of a shape (whether it was a hollow band or a filled drum volume), but not by changes in color or size. We discuss how these new results constrain models of sensory memory and SFM processing.

  9. [Exploration of salt in Poland in the second half of the 18th century]. (United States)

    Danowska, Ewa


    Following the First Partition in 1772, Poland lost the salt mines in Wieliczka, Bochnia and in the territory of Ruthenia to Austria. This was a serious blow to the economy, because since then, it became necessary to import salt, which was primarily taken advantage of by the Royal Prussian Maritime Trading Company (Pruska Kompania Morska) importing it from Austria. King Stanislaw August Poniatowski tried to initiate the exploration and exploitation of salt in the areas where it could be profitable. To this end, he ordered the exploration to Filip Carosi and Stanislaw Okraszewski, among other. The salt-works of the Castellan of Leukow, Jacek Jezierski in the town of Solca, in the Lqczyckie Region, active since 1780, was a private investment. Leopold von Beust's Kompania akcyjna obtained salt from a brine near the town of Busko, and Kompania z Osob Krajowych--from a brine in the town of Raczki nad Pilica. In 1782, the King appointed The Ore Commission (Komisja Kruszcowa), consisted of twelve commissioners, in order to conduct the exploration for minerals, including salt, their extraction and further administration. The Crown Treasury Commission (Komisja Skarbu Koronnego), a magistracy dealing with, among others, the economy of the country in a broad sense, was also involved in the exploration and exploatation of salt. At its command, in the summer of 1788, Tadeusz Czacki made a tour of the Kielce region in search of traces of salt. In view of the important events of the Four-Year Sejm (Sejm Czteroletni) and the subsequent loss of independence, the subject of salt exploration had to be abandoned.

  10. The Categorical Perception of the Music Scale a Challenge before the Microtonal Music

    Directory of Open Access Journals (Sweden)

    Ivan Kostadinov Yanakiev


    Full Text Available The text examines the phenomenon of categorical perception of musical pitch as defined by John Sloboda (1999, Jane A. and William Siegel (1977, Stefan Koelsch (2012, and William Yost (2013, in their researches in the field of music psychology. The paper states the hypothesis that the current system of dividing the octave in twelve equal semitones do not employ the human physical capabilities for defining pitch to their full extend. On the contrary, the reviewed literature testify for the existence of a strong tendency to categorically label and perceive non equally tempered intervals with different but close to each other magnitudes (widths as the same. This tendency is stronger in professionally trained musicians than in non-musicians. A short historical excursion to the 21 tone 1/6 syntonic coma meantone temperament, recommended by both Leopold (1856 and Wolfgang Amadeus Mozart (1965, is included as an example for better utilization of the musicians’ potential to distinguish pitch and intervals, which had been employed in practice. The text continues with a brief overview of the theory behind generating intonations and temperaments, based on the Equal Division of the Octave (EDO method. Finally, a short exemplary reference to Kyle Ganns’ cycle “Hyperchromatica” (2015 is made alongside with quoting his personal attitude and commentary towards the performers’ general interest for microtonal music. The paper concludes that the categorical perception of pitch in the context of the twelve-tone equal temperament may be regarded as the main challenge, which the microtonal music is facing.

    Franz Leopold Neumann (1900-1954 was a political theorist associated with the Frankfurt School. He obtained a doctoral degree in legal studies at the University of Frankfurt with the dissertation „Rechtsphilosophische Einleitung zu einer Abhandlung über das Verhältnis von Staat und Strafe“ (A Legal-Philosophical Introduction to A Treatise on the Relationship between the State and Punishment. Neumann became the German Social Democratic Party’s (SPD main legal advisor at a time when the Nazis and Hitler gained strength in Germany. At the time when Hitler came to power in 1933, the legal office had to be closed and Neumann had to flee from Germany. In London, he in 1936 obtained his second doctoral degree from the London School of Economics with the work “The Governance of the Rule of Law” under the supervision of Harold Laski and Karl Mannheim. Neumann moved to New York in 1936, where he became a member of the Institute of Social Research (also known as the “Frankfurt School” that was then in exile in the USA. In 1942, he started working for the Office of Strategic Service (OSS, where he together with Herbert Marcuse and Otto Kirchheimer analysed Nazi Germany. In 1942, Neumann published his main book is Behemoth: The Structure and Practice of National Socialism, 1933–1944 (2nd, updated edition published in 1944, one of the most profound analyses of Nazi Germany’s political economy and ideology.

  12. Weak Learner Method for Estimating River Discharges using Remotely Sensed Data: Central Congo River as a Testbed (United States)

    Kim, D.; Lee, H.; Yu, H.; Beighley, E.; Durand, M. T.; Alsdorf, D. E.; Hwang, E.


    River discharge is a prerequisite for an understanding of flood hazard and water resource management, yet we have poor knowledge of it, especially over remote basins. Previous studies have successfully used a classic hydraulic geometry, at-many-stations hydraulic geometry (AMHG), and Manning's equation to estimate the river discharge. Theoretical bases of these empirical methods were introduced by Leopold and Maddock (1953) and Manning (1889), and those have been long used in the field of hydrology, water resources, and geomorphology. However, the methods to estimate the river discharge from remotely sensed data essentially require bathymetric information of the river or are not applicable to braided rivers. Furthermore, the methods used in the previous studies adopted assumptions of river conditions to be steady and uniform. Consequently, those methods have limitations in estimating the river discharge in complex and unsteady flow in nature. In this study, we developed a novel approach to estimating river discharges by applying the weak learner method (here termed WLQ), which is one of the ensemble methods using multiple classifiers, to the remotely sensed measurements of water levels from Envisat altimetry, effective river widths from PALSAR images, and multi-temporal surface water slopes over a part of the mainstem Congo. Compared with the methods used in the previous studies, the root mean square error (RMSE) decreased from 5,089 m3s-1 to 3,701 m3s-1, and the relative RMSE (RRMSE) improved from 12% to 8%. It is expected that our method can provide improved estimates of river discharges in complex and unsteady flow conditions based on the data-driven prediction model by machine learning (i.e. WLQ), even when the bathymetric data is not available or in case of the braided rivers. Moreover, it is also expected that the WLQ can be applied to the measurements of river levels, slopes and widths from the future Surface Water Ocean Topography (SWOT) mission to be

  13. Wisconsin Partnerships to Educate and Engage Public Audiences on Climate Change Topics (United States)

    Mooney, M. E.; Ackerman, S.; Rowley, P.; Crowley Conn, K.


    The complexity and scale of climate change-related challenges requires more than one strategy to share meaningful information with public audiences. This presentation will discuss a few initiatives to engage the public originating from the University of Wisconsin-Madison. First, a local partnership between the Cooperative Institute for Meteorological Satellite Studies (CIMSS) and the Aldo Leopold Nature Center (ALNC), an informal learning center with a new climate change "classroom" which recently acquired a Science on a Sphere (SOS) exhibit. Second, an informal education project funded by the NOAA Office of Education coordinated by CIMSS in partnership with the national SOS Network with the goal of helping museum docents share meaningful interpretation of real-time weather and climate data. CIMSS staff has been conducting weather and climate discussions on a Magic Planet display for several years. This "mini-SOS" is powered by a solar panel on the roof, modeling the essential Sun-Earth connection and the first principle of climate literacy. However, the convenient proximity of CIMSS and ALNC provides a perfect opportunity to test "SOS-scale" talking points posted on a weekly docent blog to the benefit of the entire SOS Network. Two other Wisconsin projects of note include the Wisconsin Initiative on Climate Change Impacts, a partnership between the University and the Wisconsin Department of Natural Resources, and a pilot project between CIMSS and NOAA's National Weather Service to engage storm spotters in climate mitigation and stewardship. Ideally, the synergistic benefits and lessons learned from these collaborations can inform similar efforts in order to galvanize meaningful responses to climate change.

  14. [Pathography and biography of the Empress Maria Theresa]. (United States)

    Habek, D; Masić, I


    The empress and queen Maria Theresa Habsburg-Lorraine (May 13th, 1917-November 29th, 1780) bore sixteen children in the marriage with the emperor Franz I Stepha and was famous as "mother-in-law of Europe". Her brother Leopold died immediately after he was born, her sister Amalia died in the cradle and Maria Ana died of perinatal complications at the birth of a dead infant in 1744. The famous hereditary facial dysmorphia of the "Hasburg jawe" wasn't noticed in Maria Theresa's surviving children. In October of 1738, after giving birth to her daughter Ana, a manual lysis of the placenta was performed due to the retained placenta and postpartal bleeding. In 1741 her daughter Carolina died, and in 1767 her daughter Josepha died of small pox. Her daughter Elizabeth remained deformed by the pock marks, and Maria Christina got a puerperal sepsis, but surprisingly, didn't die. Maria Antoinette ended under a guillotine in France, along with her husband Luis XVI. Maria Theresa's father, Karl VI died of the cholecystopankreatitis and peritonitis, and her husband and co-ruler most probably died of acute coronary incident in August 18th, 1765. After her husband's death she started suffering from depression with steady necrophile obsessions. Maria Theresa suffered from a chronical obstructional pulmonary disease (asthma), rehumatic syndromes, hypertension and anxiodepressive syndromes. In 1767 she had small pox. In November 11th 1780 she caught a cold which grew into a pneumonia with high fever. She died of cardiopulmonal dedompensation preceded by pneumonia and asthma.

  15. Sleep stability and cognitive function in an Arctic Martian analogue. (United States)

    Gríofa, Marc O; Blue, Rebecca S; Cohen, Kenneth D; O'Keeffe, Derek T


    Human performance is affected by sleep disruption and sleep deprivation can critically affect mission outcome in both spaceflight and other extreme environments. In this study, the seven-person crew (four men, three women) lived a Martian sol (24.65 h) for 37 d during a long-term stay at the Flashline Mars Arctic Research Station (FMARS) on Devon Island, Canada. Crewmembers underwent cardiopulmonary monitoring for signs of circadian disruption and completed a modified Pittsburgh Sleep Diary to monitor subjective fatigue. Crewmembers underwent cognitive testing to identify the effects, if any, of sleep disruption upon cognitive skill. A Martian sol was implemented for 37 d during the Arctic mission. Each crewmember completed an adapted version of the Pittsburgh Sleep Diary in tandem with electrocardiograph (ECG) cardiopulmonary monitoring of sleep by the Cardiac Adapted Sleep Parameters Electrocardiogram Recorder (CASPER). Crewmembers also underwent cognitive testing during this time period. Sleep diary data indicate improvement in alertness with the onset of the sol (fatigue decreasing from 5.1 to 4.0, alertness increasing from 6.1 to 7.0). Cardiopulmonary data suggest sleep instability, though trends were not statistically significant. Crewmember decision speed time scores improved from pre-Mars to Mars (average improving from 66.5 to 84.0%), though the remainder of cognitive testing results were not significant. While subjective data demonstrate improved sleep and alertness during the sol, objective data demonstrate no significant alteration of sleep patterns. There was no apparent cognitive decline over the course of the mission.

    Attfield, Kathleen R; Dobson, Christine B; Henn, Jennifer B; Acosta, Meileen; Smorodinsky, Svetlana; Wilken, Jason A; Barreau, Tracy; Schreiber, Merritt; Windham, Gayle C; Materna, Barbara L; Roisman, Rachel


    On August 24, 2014, at 3:20 a.m., a magnitude 6.0 earthquake struck California, with its epicenter in Napa County (1). The earthquake was the largest to affect the San Francisco Bay area in 25 years and caused significant damage in Napa and Solano counties, including widespread power outages, five residential fires, and damage to roadways, waterlines, and 1,600 buildings (2). Two deaths resulted (2). On August 25, Napa County Public Health asked the California Department of Public Health (CDPH) for assistance in assessing postdisaster health effects, including earthquake-related injuries and effects on mental health. On September 23, Solano County Public Health requested similar assistance. A household-level Community Assessment for Public Health Emergency Response (CASPER) was conducted for these counties in two cities (Napa, 3 weeks after the earthquake, and Vallejo, 6 weeks after the earthquake). Among households reporting injuries, a substantial proportion (48% in Napa and 37% in western Vallejo) reported that the injuries occurred during the cleanup period, suggesting that increased messaging on safety precautions after a disaster might be needed. One fifth of respondents overall (27% in Napa and 9% in western Vallejo) reported one or more traumatic psychological exposures in their households. These findings were used by Napa County Mental Health to guide immediate-term mental health resource allocations and to conduct public training sessions and education campaigns to support persons with mental health risks following the earthquake. In addition, to promote community resilience and future earthquake preparedness, Napa County Public Health subsequently conducted community events on the earthquake anniversary and provided outreach workers with psychological first aid training.

  17. Status of MUSIC, the MUltiwavelength Sub/millimeter Inductance Camera (United States)

    Golwala, Sunil R.; Bockstiegel, Clint; Brugger, Spencer; Czakon, Nicole G.; Day, Peter K.; Downes, Thomas P.; Duan, Ran; Gao, Jiansong; Gill, Amandeep K.; Glenn, Jason; Hollister, Matthew I.; LeDuc, Henry G.; Maloney, Philip R.; Mazin, Benjamin A.; McHugh, Sean G.; Miller, David; Noroozian, Omid; Nguyen, Hien T.; Sayers, Jack; Schlaerth, James A.; Siegel, Seth; Vayonakis, Anastasios K.; Wilson, Philip R.; Zmuidzinas, Jonas


    We present the status of MUSIC, the MUltiwavelength Sub/millimeter Inductance Camera, a new instrument for the Caltech Submillimeter Observatory. MUSIC is designed to have a 14', diffraction-limited field-of-view instrumented with 2304 detectors in 576 spatial pixels and four spectral bands at 0.87, 1.04, 1.33, and 1.98 mm. MUSIC will be used to study dusty star-forming galaxies, galaxy clusters via the Sunyaev-Zeldovich effect, and star formation in our own and nearby galaxies. MUSIC uses broadband superconducting phased-array slot-dipole antennas to form beams, lumpedelement on-chip bandpass filters to define spectral bands, and microwave kinetic inductance detectors to sense incoming light. The focal plane is fabricated in 8 tiles consisting of 72 spatial pixels each. It is coupled to the telescope via an ambient-temperature ellipsoidal mirror and a cold reimaging lens. A cold Lyot stop sits at the image of the primary mirror formed by the ellipsoidal mirror. Dielectric and metal-mesh filters are used to block thermal infrared and out-ofband radiation. The instrument uses a pulse tube cooler and 3He/ 3He/4He closed-cycle cooler to cool the focal plane to below 250 mK. A multilayer shield attenuates Earth's magnetic field. Each focal plane tile is read out by a single pair of coaxes and a HEMT amplifier. The readout system consists of 16 copies of custom-designed ADC/DAC and IF boards coupled to the CASPER ROACH platform. We focus on recent updates on the instrument design and results from the commissioning of the full camera in 2012.

  18. Use of dye tracing in water-resources investigations in Wyoming, 1967-94 (United States)

    Wilson, J.F.; Rankl, J.G.


    During 1967-94, the U.S. Geological Survey made numerous applications of dye tracing for water-resources investigations in Wyoming. Many of the dye tests were done in cooperation with other agencies. Results of all applications, including some previously unpublished, are described. A chronology of past applications in Wyoming and a discussion of potential future applications are included. Time-of-travel and dispersion measurements were made in a 113-mile reach of the Wind/Bighorn River below Boysen Dam; a 117-mile reach of the Green River upstream from Fontenelle Reservoir and a 70-mile reach downstream; parts of four tributaries to the Green (East Fork River, 39 miles; Big Sandy River, 112 miles; Horse Creek, 14 miles; and Blacks Fork, 14 miles); a 75-mile reach of the Little Snake River along the Wyoming-Colorado State line; and a 95-mile reach of the North Platte River downstream from Casper. Reaeration measurements were made during one of the time-of-travel measurements in the North Platte River. Sixty-eight dye-dilution measurements of stream discharge were made at 22 different sites. These included 17 measurements for verifying the stage-discharge relations for streamflow-gaging stations on North and South Brush Creeks near Saratoga, and total of 29 discharge measurements at 12 new stations at remote sites on steep, rough mountain streams crossing limestone outcrops in northeastern Wyoming. The largest discharge measured by dye tracing was 2,300 cubic feet per second. In karst terrane, four losing streams-North Fork Powder River, North Fork Crazy Woman Creek, Little Tongue River, and Smith Creek-were dye-tested. In the Middle Popo Agie River, a sinking stream in Sinks Canyon State Park, a dye test verified the connection of the sink (Sinks of Lander Cave) to the rise, where flow in the stream resumes.

  19. Study and mathematical model of ultra-low gas burner

    International Nuclear Information System (INIS)

    Gueorguieva, A.


    The main objective of this project is prediction and reduction of NOx and CO 2 emissions under levels recommended from European standards for gas combustion processes. A mathematical model of burner and combustion chamber is developed based on interacting fluid dynamics processes: turbulent flow, gas phase chemical reactions, heat and radiation transfer The NOx prediction model for prompt and thermal NOx is developed. The validation of CFD (Computer fluid-dynamics) simulations corresponds to 5 MWI burner type - TEA, installed on CASPER boiler. This burner is three-stream air distribution burner with swirl effect, designed by ENEL to meet future NOx emission standards. For performing combustion computer modelling, FLUENT CFD code is preferred, because of its capabilities to provide accurately description of large number of rapid interacting processes: turbulent flow, phase chemical reactions and heat transfer and for its possibilities to present wide range of calculation and graphical output reporting data The computational tool used in this study is FLUENT version 5.4.1, installed on fs 8200 UNIX systems The work includes: study the effectiveness of low-NOx concepts and understand the impact of combustion and swirl air distribution and flue gas recirculation on peak flame temperatures, flame structure and fuel/air mixing. A finite rate combustion model: Eddy-Dissipation (Magnussen-Hjertager) Chemical Model for 1, 2 step Chemical reactions of bi-dimensional (2D) grid is developed along with NOx and CO 2 predictions. The experimental part of the project consists of participation at combustion tests on experimental facilities located in Livorno. The results of the experiments are used, to obtain better vision for combustion process on small-scaled design and to collect the necessary input data for further Fluent simulations

  20. Helicopter Based Magnetic Detection Of Wells At The Teapot Dome (Naval Petroleum Reserve No. 3 Oilfield: Rapid And Accurate Geophysical Algorithms For Locating Wells (United States)

    Harbert, W.; Hammack, R.; Veloski, G.; Hodge, G.


    In this study Airborne magnetic data was collected by Fugro Airborne Surveys from a helicopter platform (Figure 1) using the Midas II system over the 39 km2 NPR3 (Naval Petroleum Reserve No. 3) oilfield in east-central Wyoming. The Midas II system employs two Scintrex CS-2 cesium vapor magnetometers on opposite ends of a transversely mounted, 13.4-m long horizontal boom located amidships (Fig. 1). Each magnetic sensor had an in-flight sensitivity of 0.01 nT. Real time compensation of the magnetic data for magnetic noise induced by maneuvering of the aircraft was accomplished using two fluxgate magnetometers mounted just inboard of the cesium sensors. The total area surveyed was 40.5 km2 (NPR3) near Casper, Wyoming. The purpose of the survey was to accurately locate wells that had been drilled there during more than 90 years of continuous oilfield operation. The survey was conducted at low altitude and with closely spaced flight lines to improve the detection of wells with weak magnetic response and to increase the resolution of closely spaced wells. The survey was in preparation for a planned CO2 flood to enhance oil recovery, which requires a complete well inventory with accurate locations for all existing wells. The magnetic survey was intended to locate wells that are missing from the well database and to provide accurate locations for all wells. The well location method used combined an input dataset (for example, leveled total magnetic field reduced to the pole), combined with first and second horizontal spatial derivatives of this input dataset, which were then analyzed using focal statistics and finally combined using a fuzzy combination operation. Analytic signal and the Shi and Butt (2004) ZS attribute were also analyzed using this algorithm. A parameter could be adjusted to determine sensitivity. Depending on the input dataset 88% to 100% of the wells were located, with typical values being 95% to 99% for the NPR3 field site.

  1. Aerial gamma ray and magnetic survey: Powder River R and D Project. Portions of the: Forsyth and Hardin, Montana, and the Sheridan, Arminto, Newcastle, and Gillette, Wyoming Quadrangles. Final report

    International Nuclear Information System (INIS)


    During the months of August through September, 1978, geoMetrics, Inc. flew approximately 1520 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and southern Montana within four 1 0 x 2 0 NTMS quadrangles (Arminto, Sheridan, Hardin and Forsyth), and 1390 lines miles in the detail area in eastern Wyoming, as part of the Department of Energy's National Uranium Resource Evaluation program. All radiometric and magnetic data were fully reduced and interpreted by geoMetrics, and are presented as three volumes (one Volume I and two Volume II's) in this report. The survey area lies largely within the northern Great Plains Physiographic Province. The deep Powder River Basin is the dominant structure in the area. Portions of the Casper Arch, Big Horn Uplift, and Porcupine Dome fall within the western limits of the area. The Basin is one of the largest and deepest in the northern Great Plains and contains over 17,000 feet of Phanerozoic sediments at its deepest point. Economic deposits of oil, coal, bentonite and uranium are found in the Tertiary and/or Cretaceous rocks of the Basin. Epigenetic uranium deposits lie primarily in the Pumpkin Buttes - Turnercrest districts within arkosic sandstones of the Paleocene Fort Union Formation. A total of 62 groups of statistical values for the R and D area and 127 for the Arminto Detail in the uranium window meet the criteria for valid anomalies and are discussed in their respective interpretation sections. Most anomalies lie in the Tertiary sediments of the Powder River Basin. Some of the anomalies in the Arminto Detail are clearly related to mines or prospects

    We present the array performance and astronomical images from early science results from MUSTANG-2, a 90 GHz feedhorn-coupled, microwave SQUID-multiplexed TES bolometer array operating on the Robert C. Byrd Green Bank Telescope (GBT). MUSTANG-2 was installed on the GBT on December 2, 2016 and immediately began commissioning efforts, followed by science observations, which are expected to conclude June 2017. The feedhorn and waveguide-probe-coupled detector technology is a mature technology, which has been used on instrument including the South Pole Telescope, the Atacama Cosmology Telescope, and the Atacama B-mode Search telescope. The microwave SQUID readout system developed for MUSTANG-2 currently reads out 66 detectors with a single coaxial cable and will eventually allow thousands of detectors to be multiplexed. This microwave SQUID multiplexer combines the proven abilities of millimeterwave TES detectors with the multiplexing capabilities of KIDs with no degradation in noise performance of the detectors. Each multiplexing device is read out using warm electronics consisting of a commercially available ROACH board, a DAC/ADC card, and an Intermediate Frequency mixer circuit. The hardware was originally developed by the UC Berkeley Collaboration for Astronomy Signal Processing and Electronic Research (CASPER) group, whose primary goal is to develop scalable FPGA-based hardware with the flexibility to be used in a wide range of radio signal processing applications. MUSTANG-2 is the first on-sky instrument to use microwave SQUID multiplexing and is available as a shared-risk/PI instrument on the GBT. In MUSTANG-2's first season 7 separate proposals were awarded a total of 230 hours of telescope time.

  3. Comparison of Numerical Approaches to a Steady-State Landscape Equation (United States)

    Bachman, S.; Peckham, S.


    A mathematical model of an idealized fluvial landscape has been developed, in which a land surface will evolve to preserve dendritic channel networks as the surface is lowered. The physical basis for this model stems from the equations for conservation of mass for water and sediment. These equations relate the divergence of the 2D vector fields showing the unit-width discharge of water and sediment to the excess rainrate and tectonic uplift on the land surface. The 2D flow direction is taken to be opposite to the water- surface gradient vector. These notions are combined with a generalized Manning-type flow resistance formula and a generalized sediment transport law to give a closed mathematical system that can, in principle, be solved for all variables of interest: discharge of water and sediment, land surface height, vertically- averaged flow velocity, water depth, and shear stress. The hydraulic geometry equations (Leopold et. al, 1964, 1995) are used to incorporate width, depth, velocity, and slope of river channels as powers of the mean-annual river discharge. Combined, they give the unit- width discharge of the stream as a power, γ, of the water surface slope. The simplified steady-state model takes into account three components among those listed above: conservation of mass for water, flow opposite the gradient, and a slope-discharge exponent γ = -1 to reflect mature drainage networks. The mathematical representation of this model appears as a second-order hyperbolic partial differential equation (PDE) where the diffusivity is inversely proportional to the square of the local surface slope. The highly nonlinear nature of this PDE has made it very difficult to solve both analytically and numerically. We present simplistic analytic solutions to this equation which are used to test the validity of the numerical algorithms. We also present three such numerical approaches which have been used in solving the differential equation. The first is based on a

    Full Text Available En la presente investigación se realizó una clasificación y valoración de impacto de los residuos sólidos generados en las playas de Riohacha, desde Valle de los Cangrejos hasta el Barrio Marbella. Se seleccionaron cinco estaciones de muestreo; en cada una se ubicaron transectos perpendiculares a la línea de costa; sobre estos se trazaron cuadrantes paralelos para la recolección de residuos sólidos. Además, se aplicaron encuestas a los usuarios y vendedores de las playas para determinar la percepción de olores ofensivos y se cuantificó la carga turística. Los datos de residuos se analizaron con el software estadístico SPSS 12,0 a través de la prueba Kruskal-wallis con el 97,5% de significancia y se valoró el impacto con el Método de Leopold (1971. En el inventario realizado los materiales que registraron mayor presencia fueron materia orgánica, plásticos, misceláneos y vidrios, siendo los residuos sólidos orgánicos los que obtuvieron mayor porcentaje. Las mayores concentraciones de usuarios se presentaron en la Zona Activa (ZA y Zona Pasiva (ZP, coincidiendo con la cantidad de residuos recolectados en cada estación de muestreo. Los olores ofensivos de mayor incidencia fueron basura, orina, excrementos humano y animal. La cantidad y el tipo de material están condicionados por las características del área y la influencia de actividades socioeconómicas. Las cantidades de residuos sólidos en las estaciones durante el 1º y 2º muestreo no presentaron diferencias significativas, siendo las principales causas de generación la disposición de desechos por residentes y visitantes, la pesca y la deposición de excrementos en la playa.

  6. Literatura e transgressão: Sade, Masoch e Bataille

    Directory of Open Access Journals (Sweden)

    Renata Lopes Pedro


    Full Text Available Cet article a l'intention de mettre en rapport Littérature et Transgression, à travers l’analyse de trois des auteurs considérés « libertins » : Sade, Masoch et Bataille. Les romans de Sade sont des romans érotiques, écrits pour satisfaire son immense excitation sexuelle et la partager éventuellement avec quelqu’un d’autre. Sade nous présente ses héros à titre d'exemples, mais il faut de remarquer qu' il les qualifie toujours de pervers, vauriens, monstres. Les sinistres orgies de Sade sont des cauchemars, donc l'imaginable peut être admiré, à cause de son intensité d'expression, tant que le réalisable correspondant serait désapprouvé. Néanmoins, les tendance à traiter des sévices sexuels, en prétendant que les patients aussi bien que les agents sentaient une satisfaction spéciale à cela, a pris un sens entièrement nouveau avec Leopold de Sacher-Masoch, un homme énigmatique qui ne menait à bien l'acte sexuel qu’à condition d'être frappé et humilié par la femme que il désirait. Bataille est l'auteur qui présente un sens noir de l'érotique, de ses dangers de séduction et d'humiliation. Dans son oeuvre, Histoire de l'Oeil, il se produit un violent processus de dépersonnalisation, les traits qui distinguent le visage s'effacent et il ne reste que des organes livrés à la convulsion interne de la chair, opérant dans un corps qui renonce à la médiation de l'esprit. Dans cette oeuvre, le sujet de la pornographie n'est pas le sexe, mais le décès.

  8. Some Challenges of Deep Mining†

    Directory of Open Access Journals (Sweden)

    Charles Fairhurst


    Full Text Available An increased global supply of minerals is essential to meet the needs and expectations of a rapidly rising world population. This implies extraction from greater depths. Autonomous mining systems, developed through sustained R&D by equipment suppliers, reduce miner exposure to hostile work environments and increase safety. This places increased focus on “ground control” and on rock mechanics to define the depth to which minerals may be extracted economically. Although significant efforts have been made since the end of World War II to apply mechanics to mine design, there have been both technological and organizational obstacles. Rock in situ is a more complex engineering material than is typically encountered in most other engineering disciplines. Mining engineering has relied heavily on empirical procedures in design for thousands of years. These are no longer adequate to address the challenges of the 21st century, as mines venture to increasingly greater depths. The development of the synthetic rock mass (SRM in 2008 provides researchers with the ability to analyze the deformational behavior of rock masses that are anisotropic and discontinuous—attributes that were described as the defining characteristics of in situ rock by Leopold Müller, the president and founder of the International Society for Rock Mechanics (ISRM, in 1966. Recent developments in the numerical modeling of large-scale mining operations (e.g., caving using the SRM reveal unanticipated deformational behavior of the rock. The application of massive parallelization and cloud computational techniques offers major opportunities: for example, to assess uncertainties in numerical predictions; to establish the mechanics basis for the empirical rules now used in rock engineering and their validity for the prediction of rock mass behavior beyond current experience; and to use the discrete element method (DEM in the optimization of deep mine design. For the first time, mining

  9. ESA Press Event: See Mars Express before its departure to the Red Planet (United States)


    There will be ten participants: four ESA astronauts (Pedro Duque, Leopold Eyharts, Paolo Nespoli and Thomas Reiter), four Japanese astronauts from NASDA (Takao Doi, Koichi Wakata, Satoshi Furukawa and Aikihido Hoshide) and two NASA astronauts (Nicole Passonno Stott and Stephanie D. Wilson). The main objective of this training session is to prepare the astronauts for the tasks they will have to perform when the Japanese experiment module (JEM) and ESA's Columbus laboratory are docked with the core of the International Space Station over the years ahead. After completing their training and certification, the astronauts will be assigned to long-duration missions to the ISS. The advanced training at the EAC will focus on the Columbus systems and the Automated Transfer Vehicle (ATV). It will consist of 24 classroom lectures on the Columbus and ATV systems and 4 on payloads, and 2 sessions in the Columbus Trainer. Instructors are being provided by Astrium for the Columbus systems and Alenia Spazio for the ATV, with ESA/EAC staff as mentors for the Columbus payloads. The astronauts are scheduled to visit Astrium in Bremen on 30 August to get acquainted with the flight unit of the Columbus laboratory module currently undergoing integration. This group of astronauts started their advanced training in April 2001 at NASA's Johnson Space Center (JSC), Houston, where they attended a first course on the US segment of the International Space Station. This was followed by training on the JEM system at NASDA's Tsukuba Space Center, Japan, in December 2001 - January 2002 and additional training at the JSC in May 2002. At the beginning of next year the group will be returning to Tsukuba for training on Japanese payloads. Hands-on sessions on Columbus Payload Training Models are scheduled for the second half of 2003, again at ESA's European Astronaut Centre. On Thursday 5 September, between 16:30 and 18:30 hrs, the astronauts and other ESA specialists will be available for interviews

  10. The Theremin in the Emergence of Electronic Music (United States)

    Glinsky, Albert Vincent


    This study examines the invention and history of the Theremin electronic musical instrument in relation to the emergence of electronic music. After Lee De Forest invented the oscillator in 1915, revolutionizing the radio industry, Russian inventor Leon Theremin (born Lev Sergeyevich Termen, 1896), utilized this technology in 1919 to develop the first fully functional electronic musical instrument. Named after its inventor, the Theremin employed a unique operational configuration. Without touching the instrument, the player controlled pitch through relative proximity of the right hand to a vertical antenna, and volume through similar movements of the left hand in relation to a horizontal antenna. The instrument employed a heterodyne, or beat frequency system, and boasted a range of three to four octaves. On the invitation of Lenin, Theremin travelled throughout Russia, successfully demonstrating his instrument, and came to Europe in 1927, where his sensational presentations caused considerable excitement in Germany, France and England. Critics hailed his instrument as a revolution in music, and he quickly garnered international recognition. Later in 1927 Theremin travelled to the United States where he remained until 1938. His years in the U.S. brought public, professional and corporate support, and in 1929 he sold the patent rights to his instrument to the Radio Corporation of America which manufactured and sold 500 instruments between 1929 and 1931. The inventor collaborated with Leopold Stokowski on the development of a fingerboard Theremin which the conductor employed in the Philadelphia Orchestra from 1929 to 1931. Theremin performed as soloist with the New York Philharmonic-Symphony Orchestra and the Cleveland Orchestra, and frequently presented coast to coast broadcasts with his instrument. He attracted a loyal following of students, a few of whom performed extensively on his instrument across the U.S. and Europe. In his later years in America, Theremin

  11. The Physicist and Astronomer Christoper Scheiner - Biography Letters, Works (United States)

    Daxecker, Franz

    The Jesuit priest Christopher Scheiner was one of the most influential astronomers of the first half of the 17th century. He was a creative and down-to-earth natural scientist who worked in the fields of astronomy, physics, optics and ophthalmology, while following his vocations as university lecturer, church builder and pastor. In scientific matters he was Galilei's opponent. Their dispute centred on the priority of discovery in regard to the sunspots. Scheiner was not the first to discover the sunspots, but he gave the most detailed account thereofin his main work "Rosa Ursina sive Sol". He was, however, ceaseless in his defense of the geocentric system. In 1891, Anton v.Braunmühl published a biography of Father Scheiner. Ever since then, new documents have come to light, justifying the publication of a new biography. Among the documents now available is Scheiner's hitherto unknown dissertation. Notes taken during his lectures in Ingolstadt provide valuable information on astronomy using the telescope, an invention of his lifetime. His exchange of letters with personalities like Archduke Leopold V of Austria-Tyrol, with scientists like Magini, Galilei, Gassendi, Kepler and confriars Rader, Guldin, Alber, Minutuli, Cysat und Kircher is a source of precious insights. Letters to Scheiner from the Father Generals of his order display evidence of his superiors' zero tolerance for the helincentric system. They also disclose Scheiner's wish to become a missionary in China, the financial difficulties he faced while trying to find a publisher for his "Rosa Ursina sive Sol" and his personal shortcomings. A Scheiner obituary from 1650 was found in Cracow in 2001. It contains information on the troublesome last years of his life and has finally allowed us to determine the year of his birth. Scheiner's personality has been praised as well as criticized by many authors - sometimes depending on their ideological backgrounds. This holds true especially regarding the argument

  13. Where High-Tech Meets High-Touch: an example of effective cross-disciplinary collaboration in education (United States)

    Holzhauer, B.; Mooney, M. E.


    How can non-formal education programs effectively blend hands-on, place-based field science lessons with technology and digital media to teach abstract global concepts in a local setting? Using climate change as an overarching concept, the Aldo Leopold Nature Center (ALNC) in Madison, WI, is developing exhibits and digital curricula, strengthened through partnerships with local and national experts from scientific and education fields, to effectively increase the public's interest in and understanding of science and technology, how the world works, and what we can do to adapt, mitigate, and innovate sustainable solutions. The exhibits and multimedia content, centered on topics such as climate, energy, weather, and phenology, have been developed in consultation with partners like the National Academy of Sciences and various departments at the University of Wisconsin (UW). Outdoor "high-touch" programs are complemented with "high-tech" exhibits and media, including touchscreen kiosks and the National Oceanic and Atmospheric Administration's (NOAA) Science On a Sphere® global display system, tying together multimedia experiences with peer-reviewed cutting-edge science to ensure maximum comprehension by appealing and connecting to learners of all ages and learning modalities. The curriculum is being developed in alignment with local and national education standards and science and climate literacy frameworks (such as "The Essential Principles of Climate Sciences," U.S. Global Change Research Program / U.S. Climate Change Science Program). Its digital format allows it to be easily adapted to visitors' learning styles and cognitive levels and updated with relevant new content such as real-time climate data or current visualizations from the UW Cooperative Institute for Meteorological Satellite Studies. Drawing upon ALNC's award-winning environmental education experiences, professional development networks such as NOAA's Climate Stewards Education Program, and existing

Acknowledges that whereas river channels that form within their unmodified alluvium evolve into optimal minimum-energy systems, exogenic variables, such as riparian or aquatic vegetation, can cause significant variations in resultant river-styles. We specifically attempt to address Luna Leopold's lament in 1994 that no clearly expressed philosophy explains the remarkable self-adjustment of alluvial channels.

  16. Testosterone deficiency: a historical perspective

    Directory of Open Access Journals (Sweden)

    Eberhard Nieschlag


    Full Text Available The biological effects of the testes and testosterone are known since antiquity. Aristotle knew the effects of castration and his hypothesis on fertilization is one of the first scientific encounters in reproductive biology. Over centuries, castration has been performed as punishment and to produce obedient slaves, but also to preserve the soprano voices of prepubertal boys. The Chinese imperial (and other oriental courts employed castrates as overseers in harems who often obtained high-ranking political positions. The era of testis transplantation and organotherapy was initiated by John Hunter in London who transplanted testes into capons in 1786. The intention of his experiments was to prove the 'vital principle' as the basis for modern transplantation medicine, but Hunter did not consider endocrine aspects. Arnold Adolph Berthold postulated internal secretion from his testicular transplantation experiments in 1849 in Göttingen and is thus considered the father of endocrinology. Following his observations, testicular preparations were used for therapy, popularized by self-experiments by Charles-Edouard Brown-Séquard in Paris (1889, which can at best have placebo effects. In the 1920s Sergio Voronoff transplanted testes from animals to men, but their effectiveness was disproved. Today testicular transplantation is being refined by stem cell research and germ cell transplantation. Modern androgen therapy started in 1935 when Enrest Lacquer isolated testosterone from bull testes in Amsterdam. In the same year testosterone was chemically synthesized independently by Adolf Butenandt in Göttingen and Leopold Ruzicka in Basel. Since testosterone was ineffective orally it was either compressed into subcutaneous pellets or was used orally as 17α-methyl testosterone, now obsolete because of liver toxicity. The early phases of testosterone treatment coincide with the first description of the most prominent syndromes of hypogonadism by Klinefelter, by

    Full Text Available The 20th Croatian meeting of chemists and chemical engineers was a proper occasion to consider the past meetings and their role in the development of Croatian chemistry and chemical engineering last 40 years, because these meetings reflect to a large extent the state of these sciences in Croatia. The circumstances that lead to establishment of the Croatian meetings of chemists and chemical engineers and the role of Professor Marijan Laaan (1919-1981 who started these meetings by organizing the first one are described. He also organized the second and the seventh meeting. All persons who chaired these meetings are mentioned, as well as all the lecturers who won the Nobel Prize in chemistry. Especially emphasized is the participation of Vladimir Prelog (1906-1998 since the twentieth meeting was dedicated to him and to Leopold Ružička (1887-1976 - two excellent Croatian chemists who for their first-class research in organic chemistry won the Nobel Prize (Ružička in 1939 and Prelog 1975. The places where the meetings were held are listed. The structure of the meetings when the change of the meetings' title happened is delineated and the representation of various branches of chemistry according to the number of contributions is discussed. Similarly, the Croatian institutions according to the number ofcontributions of their staff-members and the contributors with the highest number of communications at each meeting are pointed out. Emphasized is the international character of these meetings and the countries from which the participants came are listed. Finally, only one contribution is discussed in detail - the report by Kata Mlinarić-Majerski and Zdenko Majerski on the preparation of [3.1.1]propellane inserted in the structure of adamantane. Adamantane chemistry in Croatia started with the first ever adamantane synthesis in 1941, when Prelog and Seiwerth prepared this cage hydrocarbon and is still going strong due to efforts by Kata Mlinaria

  1. Results from the Modern Eddington Experiment (United States)

    Schaefer, Bradley E.; Hynes, Robert I.


    The original Eddington Eclipse Experiment (for the 29 May 1919 total solar eclipse) was a test of Einstein's General Relativity, which predicted that the apparent positions of stars near the eclipsed Sun would be shifted outward by up to 1.7". Their results were from 7 stars on 7 plates, with the measured shift at the solar limb of 1.98±0.12". On 6 November 1919, Eddington announced the triumph of Einstein, with many far-reaching effects. To further test General Relativity, the basic 'Eddington eclipse experiment' was run successfully at six later eclipses (the last in 1973), all with only ~10% accuracy.Over the last few years it has become possible to move past the old technology of photographic plates, due to the production of large-scale monochromatic CCD chips. A large number of pixels across is required so that a large field-of-view can go along with adequate resolution. These chips are now commercially available. The perfect opportunity arose with the 21 August 2017 total solar eclipse. Suddenly, it was possible for ordinary astronomers to test Einstein with simple off-the-shelf equipment.We ran a Modern Eddington Experiment from Casper Wyoming. We used the SBIG STX 16803 CCD camera (4096X4096, 9 micron pixels), along with a TeleVue NP101is APO refractor (4.0" aperture, F=540 mm). After experiments, it was decided to run without any filter. The plate scale was near 382 "/mm, the pixel size was 3.4", and the field-of-view was 3.9°X3.9°. We obtained 39 1-second images of star fields centered (with substantial shifts between images) in the dark sky 7 hours before the eclipse, for the purpose of mapping out optical distortions and CCD imperfections. The system was untouched even until the eclipse was over. During the 146-second totality, with slight cirrus clouds, we obtained 11 eclipse images, with 1.0 and 0.5 second exposures, showing over 60 stars (to SNR=10) from 53"-155" from the Sun-center.The analysis is currently underway.

    Harman, P. K.


    Reaching for the Stars: NASA Science for Girl Scouts (Girl Scout Stars) engages Girl Scouts in observing the 2017 eclipse. Three councils are host-sponsors of Girl Scout Total Eclipse Destinations,. Total Eclipse of the Heartland, sponsored by Girl Scouts of Southern Illinois, begins with planetarium, and science center visits in St. Louis, and transits to Carbondale for the eclipse. The Great Eclipse Adventure, sponsored by the Girl Scouts of the Missouri Heartland, features hands-on science activities led by Astronomy and Physics faculty and grad students at University of Missouri, Columbia, MO, and observing the eclipse at a camp nearby. Eyes to the Sky: A Once in a Lifetime Destination, by the Girl Scouts of South Carolina - Mountains to Midlands, visits a Challenger Center, a planetarium, and observatory, and culminates at Camp MaBak, Marietta, SC. Girl Scout Destinations are travel adventures, for individual girls ages 11 and older, that are inspiring, life-changing experiences. Destinations are determined via an application and review process by Girls Scouts of the USA. Girl Scout Stars also developed an Eclipse Activity Guide and kit box of materials, distributed the materials to 91 Girl Scout Councils, and delivered webinar training to councils. The eclipse materials enrich the girls' summer camp experiences with activities that promote understanding the Sun-Earth-Moon relationship, the solar system and safe eclipse viewing; and that feature science practices. Examples of the reach of the kit boxes are Girl Scouts of Montana and Wyoming Total Eclipse Event in Casper, WY, and the Girl Scouts of Northern California summer camps featuring the activities. In Girl Scouting, girls discover their skills, talents and what they care about; connect with other Girl Scouts and people in their community; and take action to change the world. This is called the Girl Scout Leadership Experience. With girl-led, hands on activities where girls can team up and work together

  4. Evaluation of thermal infrared hyperspectral imagery for the detection of onshore methane plumes: Significance for hydrocarbon exploration and monitoring (United States)

    Scafutto, Rebecca DeĺPapa Moreira; de Souza Filho, Carlos Roberto; Riley, Dean N.; de Oliveira, Wilson Jose


    Methane (CH4) is the main constituent of natural gas. Fugitive CH4 emissions partially stem from geological reservoirs (seepages) and leaks in pipelines and petroleum production plants. Airborne hyperspectral sensors with enough spectral and spatial resolution and high signal-to-noise ratio can potentially detect these emissions. Here, a field experiment performed with controlled release CH4 sources was conducted in the Rocky Mountain Oilfield Testing Center (RMOTC), Casper, WY (USA). These sources were configured to deliver diverse emission types (surface and subsurface) and rates (20-1450 scf/hr), simulating natural (seepages) and anthropogenic (pipeline) CH4 leaks. The Aerospace Corporation's SEBASS (Spatially-Enhanced Broadband Array Spectrograph System) sensor acquired hyperspectral thermal infrared data over the experimental site with 128 bands spanning the 7.6 μm-13.5 μm range. The data was acquired with a spatial resolution of 0.5 m at 1500 ft and 0.84 m at 2500 ft above ground level. Radiance images were pre-processed with an adaptation of the In-Scene Atmospheric Compensation algorithm and converted to emissivity through the Emissivity Normalization algorithm. The data was processed with a Matched Filter. Results allowed the separation between endmembers related to the spectral signature of CH4 from the background. Pixels containing CH4 signatures (absorption bands at 7.69 μm and 7.88 μm) were highlighted and the gas plumes mapped with high definition in the imagery. The dispersion of the mapped plumes is consistent with the wind direction measured independently during the experiment. Variations in the dimension of mapped gas plumes were proportional to the emission rate of each CH4 source. Spectral analysis of the signatures within the plumes shows that CH4 spectral absorption features are sharper and deeper in pixels located near the emitting source, revealing regions with higher gas density and assisting in locating CH4 sources in the field

  5. Nichols Ranch ISL Uranium Mine - A case history

    International Nuclear Information System (INIS)

    Catchpole, G.; Thomas, G.


    The Nichols Ranch ISL Uranium Mine is located in the Powder River Basin of Wyoming, U.S.A. The mine is owned and operated by Uranerz Energy Corporation (Uranerz), a U.S. corporation headquartered in Casper, Wyoming. Nichols Ranch started operations in February 2014 and is the newest uranium mine to go into production in the USA. The uranium being extracted is hosted in a sandstone, roll-front deposit at a depth ranging from 400 to 800 feet [~120 to ~240 m). The In-Situ Recovery (ISL) mining method is employed at the Nichols Ranch mine which is the method currently being utilized at most uranium mines in the USA. Environmental permit applications for the Nichols Ranch mine were submitted to the appropriate regulatory agencies in late 2007. It required more than three and a half years to obtain all the necessary permits and licenses to construct and operate the mine. Construction of the mining facilities and the first wellfield started in late 2011 and was completed in late 2013. Mining results to date have been better than anticipated and Uranerz expects to reach its 2014 production target. The most challenging part of getting a new uranium mine in production in the United States of America was the three plus years it took to get through the environmental permitting process. Uranerz was one of three companies in 2011 that applied for permits to construct and operate uranium mines in Wyoming at essentially the same time. The Nichols Ranch mine is licensed to produce up to two million pounds per year of uranium (as U_3O_8) [~770 tU] ready for shipment to the converter. At this time only the ion exchange portion of the central processing plant has been installed at Nichols Ranch with uranium loaded resin being shipped to Cameco’s nearby Smith Ranch – Highland ISL uranium mine for elution, precipitation, drying and packaging under a toll processing agreement. Cameco provides Uranerz with dried and drummed yellowcake that Uranerz owns which is shipped to the

  6. Protruding Features of Viral Capsids Are Clustered on Icosahedral Great Circles.

    Directory of Open Access Journals (Sweden)

    David P Wilson

    Full Text Available Spherical viruses are remarkably well characterized by the Triangulation (T number developed by Casper and Klug. The T-number specifies how many viral capsid proteins are required to cover the virus, as well as how they are further subdivided into pentamer and hexamer subunits. The T-number however does not constrain the orientations of these proteins within the subunits or dictate where the proteins should place their protruding features. These protrusions often take the form of loops, spires and helices, and are significant because they aid in stability of the capsid as well as recognition by the host organism. Until now there has be no overall understanding of the placement of protrusions for spherical viruses, other than they have icosahedral symmetry. We constructed a set of gauge points based upon the work affine extensions of Keef and Twarock, which have fixed relative angular locations with which to measure the locations of these features. This work adds a new element to our understanding of the geometric arrangement of spherical viral capsid proteins; chiefly that the locations of protruding features are not found stochastically distributed in an icosahedral manner across the viral surface, but instead these features are found only in specific locations along the 15 icosahedral great circles. We have found that this result holds true as the T number and viral capsids size increases, suggesting an underlying geometric constraint on their locations. This is in spite of the fact that the constraints on the pentamers and hexamer orientations change as a function of T-number, as you need to accommodate more hexamers in the same solid angle between pentamers. The existence of this angular constraint of viral capsids suggests that there is a fitness or energetic benefit to the virus placing its protrusions in this manner. This discovery may have profound impacts on identifying and eliminating viral pathogens, understanding evolutionary

  7. Evaluation of human health risk from in situ recovery uranium mining, pre-and post-mining, and post-restoration

    Ruedig, E.; Bhattacharyya, A.; Borch, T.; Johnson, T. [Colorado State University (United States); Till, J. [Risk Assessment Corporation (United States)


    In the United States, the restoration of in situ recovery (ISR) uranium mines is aimed at returning sites to pre-mining conditions. While this may seem an appropriate goal, little or no scientific information is available to justify utilizing baseline conditions for regulatory compliance. The chemical and radiological contaminants monitored for restoration compliance have not been evaluated to ensure they are proper indicators of the mitigation of risk. Pre-mining aquifers do not meet minimum United States drinking water standards, and must have an aquifer exemption in place prior to mining. Under these conditions, returning groundwater to near the original concentrations of contaminants may be unnecessary. Post-mining groundwater is also unlikely to meet standards for drinking water, but may be depleted in at least some toxic species as a result of the mining process. Here, we examine the risk to representative person from the personal use of groundwater sourced from an Uranium ISR mine. Water samples were collected from Cameco Resource's Smith Ranch-Highlands ISR Uranium mine near Casper, Wyoming, USA. Samples were acquired pre-mining, post-mining, and post-restoration. Concentrations of heavy metals and radionuclides were assessed by appropriate analytical techniques (e.g., mass spectroscopy or alpha spectroscopy) and these concentrations were used to estimate human health risk for three exposure scenarios: a scenario with high exposure, a scenario with medium exposure, and a scenario with low exposure. A simple biosphere transport model was constructed for each scenario to estimate the risk to humans from the use of contaminated waters for subsistence-related activities. Chemical and radiological risks were harmonized according to the United States Environmental Protection Agency's guidance for superfund sites. Each exposure scenario and its subsequent risk were evaluated individually for pre-mining, post-mining, and post-restoration aquifer waters

  8. Characterization of the National Petroleum Reserve No. 3 (NPR-3) Site for Naturally Occurring Radioactive Material(NORM)

    Energy Technology Data Exchange (ETDEWEB)

    White, G.J; Rood, A.S.


    The National Petroleum Reserve No. 3 site (NPR-3) near Casper, Wyoming is being prepared for transfer to private industry. Remediation of the NPR-3 site has already begun in anticipation of this transfer. This document describes the characterization of the NPR-3 site for Naturally Occurring Radioactive Materials (NORM). Data generated on radionuclide concentrations and radon emanation may be used to determine disposal options and the need for remediation at this site. A preliminary gamma survey of the NPR-3 site was conducted to identify areas of potential NORM contamination. Based on these gamma surveys, two general areas of NORM contamination were found: the North Water Flood area and the BTP-10 produced water discharge steam. A maximum surface exposure rate of 120 {micro}R h{sup -1} was observed in the North Water Flood area, with the highest readings found along the drainage channel from the area. Exposure rates dropped to background quickly with increasing distance from the center of the drainage. The maximum observed exposure rate in the BTP-10 produced water drainage was 40 {micro}R h{sup -1}. Soil and sediment sampling were concentrated in these two areas. All samples were analyzed for concentration of {sup 226}Ra, {sup 228}Ra, and {sup 40}K. Maximum {sup 226}Ra concentrations observed in the samples collected were 46 pCi g{sup -1} for soil and 78 pCi g{sup -1} for sediment. Concentrations in most samples were considerably lower than these values. Radon emanation fraction was also measured for a randomly selected fraction of the samples. The mean Rn emanation fraction measured was 0.10, indicating that on average only 10 percent of the Rn produced is released from the medium. Based on the results of these analyses, NORM contamination at the NPR-3 site is minimal, and appears to be restricted to the two general areas sampled. Concentrations of NORM radionuclides found soils and sediments in these two locations do not justify remedial actions at present

  9. Stand up and Speak Out: Professional Training Can Help Bridge the Science Communication Gap (United States)

    Neeley, E.; Simler Smith, B.; Baron, N.


    Science and technology have become firmly entrenched in our daily lives, and as a society we depend on this advanced knowledge in order to maintain - and improve - our standard of living. At the same time, social media and other advanced tools have made it easier than ever to communicate scientific findings to a wide and diverse audience. Yet herein lies a paradox: evidence shows that scientific literacy among the general public remains frustratingly low. Why does this gap remain, given such a seemingly fertile climate for scientific literacy? The answer to this question is complex, but a historical lack of communications training and support for scientists is unquestionably a part of it. Effectively explaining research findings - and why they are important - to journalists, policymakers, and other non-scientists requires specific skills that aren't accounted for in most graduate programs. For decades, in fact, scientific institutions have made communications a very low priority. Some have even discouraged outreach for fear of backlash or out of reluctance to sacrifice research time. There are indications that the culture is shifting, however. The integration of formal, for-credit communications training into graduate curricula is one promising sign. Also, professional, extracurricular communications training is now readily available from a number of sources. COMPASS (the Communication Partnership for Science and the Sea) has pioneered this latter model for more than a decade, both independently and as the lead communication trainers for the prestigious Aldo Leopold Leadership Program. Working with some of the most accomplished marine and environmental scientists in North America and beyond, COMPASS has helped equip the community with the tools to make their science clear, compelling and relevant for non-scientist audiences. We have led communication workshops for scientists at all career levels - from beginning graduate students to tenured senior faculty. A key to

    system are the hydraulic functioning, structural strength, produced erosion, service life, initial invesment and maintenance costs of different drainage systems. The followed methodology was to create a Leopold's matrix to compare among the alternatives of drainage design, asignating a puntuation from 1 to 5 to each factor that affects the functioning of the drainage. The process to decide the punctuation of every factor in each drainage design will be also explained. The alternative which obtains more puntuation represents the best available design to decrease erosion on the slopes and increase the service life. The validation of this results has been done in the field. References Goulter, I.C., 1992.

    systems learning model based on feedback and limits to perception. I focus on a part of the course that builds on connections that start in the hydrosphere and that includes some basic experiential learning about the water cycle and students' reliance on it. We measure and visualize aspects of the water cycle in nearby areas of campus (designated as an outdoor classroom and demonstration garden). The evapotranspiration flow is used to introduce notions of what can happen when flows are not sensed (e.g., invisible to us). Students use an online water footprint calculator to discover how large their water reliance is, particularly through energy generation, food consumption and food waste; and how far their water reach extends (virtual water trade). They consider the ethical implications of their water use in a world in which it is becoming a more rare resource and in some cases a valued commodity. They learn about non-utilitarian values of water based on an activity on the values of nature. They look at local, community-based efforts to improve water quality and to re-localize water dependence. A reading from Aldo Leopold puts the water cycle in a historical and cultural perspective. The water cycle is strongly interwoven with natural and human energy systems, the climate system, the carbon cycle, nutrient cycles, the rock cycle, and serves as a starting point to reach many other topics.

Samples of coal, produced water, and gas from coalbed methane drill holes throughout the Powder River Basin, many of which are adjacent to several active mine areas (figs. 1, 2), have been collected by personnel in the USGS, BLM Reservoir Management Group, and Casper and Buffalo BLM Field Offices. Sampling was done under confidentiality agreements with 29 participating CBM companies and operators. Analyses run on the samples include coal permeability, coal quality and chemistry, coal petrography and petrology, methane desorption and adsorption, produced-water chemistry, and gas composition and isotopes. The USGS has supplied results to the BLM Reservoir Management Group for their resource management needs, and data are released when the terms of the confidentiality agreements are completed and consent is obtained.

  19. Occurrence of Pesticides in Ground Water of Wyoming, 1995-2006 (United States)

    Bartos, Timothy T.; Eddy-Miller, Cheryl A.; Hallberg, Laura L.


    . Considering only detections using the CAL, triazine pesticides were detected much more frequently than all other pesticide classes, and the number of different pesticides classified as triazines was the largest of all classes. More pesticides were detected at concentrations greater than the CSALs in water from wells sampled in the fall (28 different pesticides) than in the spring (21 different pesticides). Many pesticides were detected infrequently as nearly one-half of pesticides detected in the fall and spring at concentrations greater than the CSALs were detected only in one well. Using the CSALs for pesticides analyzed for in 11 or more wells, only five pesticides (atrazine, prometon, tebuthiuron, picloram, and 3,4-dichloroaniline, listed in order of decreasing detection frequency) were each detected in water from more than 5 percent of sampled wells. Atrazine was the pesticide detected most frequently at concentrations greater than the CSAL. Concentrations of detected pesticides generally were small (less than 1 microgram per liter), although many infrequent detections at larger concentrations were noted. All detected pesticide concentrations were smaller than U.S. Environmental Protection Agency (USEPA) drinking-water standards or applicable health advisories. Most concentrations were at least an order of magnitude smaller; however, many pesticides did not have standards or advisories. The largest percentage of pesticide detections and the largest number of different pesticides detected were in samples from wells located in the Bighorn Basin and High Plains/ Casper Arch geographic areas of north-central and southeastern Wyoming. Prometon was the only pesticide detected in all eight geographic areas of the State. Pesticides were detected much more frequently in samples from wells located in predominantly urban areas than in samples from wells located in predominantly agricultural or mixed areas. Pesticides were detected distinctly less often in sa

  20. Determination of the manning coefficient from measured bed roughness in natural channels (United States)

    Limerinos, John Thomas


    difference in reliability was found between the results obtained using minimum diameters and those obtained using intermediate diameters. In analyzing the field data, the roughness parameter, n/R1/6 (where R is hydraulic radius), was related to relative smoothness, R/d (where d is a characteristic, or weighted characteristic, particle size). The parameter n/R1/6, rather than n, was used because it is directly proportional to the square root of the Darcy-Weisbach friction factor, f, which is more widely used in theoretical studies of hydraulic friction. If the transformation of n/R1/6 to vf is made, the relations obtained in this study are of a form that is identical with that of the theoretical friction equation obtained by several investigators and that derived from field data by Leopold and Wolman (1957). The constants in the equation vary, of course, with the characteristic particle size used. The relations best fitting the field data for this study were obtained by using either a characteristic particle diameter equal to the 84-percentile size (d84, the size equal to, or exceeding, that of 84 percent of the streambed particles), or a diameter obtained by weighting three characteristic particle sizes (dw, the size obtained by assigning a weight of 0.1 to d16 , a weight of 0.3 to d50 , and a weight of 0.6 to d84). The use of d84 alone gave slightly better results than the use of dw, and, in addition, the use of d84 alone is attractive from a standpoint of simplicity. It is difficult, however, to rationalize the use of d84 alone because of the implication that the distribution of sizes is irrelevant, and it matters not at all whether 84 percent of the bed material is sand or whether it is large cobbles, as long as 16 percent of the material is of greater size. Consequently, the author recommends the use of dw rather than d84 , although there was no unanimity of opinion on this recommendation among his colleagues who reviewed this paper.

    new’ character of the regime. Though she downplaysthe older emphasis on an ostensible competition between ‘liberal’ and ‘conservative’ visions of how to rule the Indies, she also argues that king William and his advisors, in their belief in a progress-oriented bureaucracy that would transform Java, did usher in a new political vision, even if this belief was at the same time deeply orientalist and, ultimately, illusory. At the same time, Schrikker carefully suggests on the basis of recent historiography that William’s ‘new’ regime relied on practices that to a large degree stemmed from the Dutch East India Company, including use of its old patronage network, its codes of conduct and – through the creation of the Nederlandsche Handel-Maatschappij and the cultivation system – its return to a mercantilist model with the support of Javanese landed elites. Schrikker also points to areas that require more research and which will probably underscore more continuities between the ancien régime and the new kingdom, such as the presumably persistent role of Chinese business leaders and Javanese nobility in the late eighteenth and early nineteenth centuries. In contrast to these stories that tend to place the accent on continuity with an earlier period, Gita Deneckere’s essay on Belgium emphatically argues for discontinuity. The periods being compared is not between William I’s regime and the period of direct French (1795-1814 or Habsburg rule that preceded it, but the significance of the Orangist regime for what happened after 1830. In sharp contrast to the official Dutch story of ‘1813-1815’ as essentially the origin of the modern democratic state, Deneckere’s concludes that the constitutions of 1814-1815 cannot be regarded as ‘modern’ and could not serve as anything other than a negative model for Belgian revolutionaries, particularly in respect to the crucial issue of ministerial responsibility.

  4. Ecologically relevant geomorphic attributes of streams are impaired by even low levels of watershed effective imperviousness (United States)

    Vietz, Geoff J.; Sammonds, Michael J.; Walsh, Christopher J.; Fletcher, Tim D.; Rutherfurd, Ian D.; Stewardson, Michael J.


    -20% of their watershed is covered by impervious surfaces (total imperviousness, TI; Bledsoe and Watson, 2001; Chin, 2006; Table 1). Many of these studies may, however, underestimate the influence of urbanization by using insensitive channel metrics and assessing streams in early stages of urbanization. Most importantly, TI, as a measure of urban density, may not adequately represent the way in which urbanization alters the master variables of flow and sediment within a watershed.Hydrologists have long recognized that, rather than the proportion of impervious cover within a watershed, it is the proportion that is directly connected to the stream through stormwater drainage systems that may be a better predictor of urban-induced hydrologic change (Leopold, 1968). Referred to as effective imperviousness (EI) the proportion of impervious cover directly connected to the stream through stormwater drainage systems may also be a better predictor of geomorphic response than is TI. Over the last decade a direct measure of EI has been found to be a better predictor of ecological response in urban streams (Walsh et al., 2012), but use of such a metric has not found its way into geomorphic studies even though TI has been found to be ineffective (e.g., Bledsoe et al., 2012). A direct measure of EI - one that specifically accounts for the drainage from each impervious surface rather than using a generic reduction factor (e.g., Booth and Jackson, 1997; Wang et al., 2001) - has not previously been used in geomorphic investigations. In this paper, we advance on past studies by testing if EI is a stronger predictor than TI for urban-induced channel change.A second limitation of previous studies of urban-induced morphologic change is the common focus on channel dimensions (Chin, 2006). These are important for infrastructure and flood protection but do not necessarily have a strong mechanistic link to stream ecosystems. While some notable exceptions exist (Finkenbine et al., 2000; Mc

    Jackson, John David


    In 1946 Philip (Phil) Russell Wallace joined the Mathematics Department of McGill University as an Associate Professor of Applied Mathematics, apparently because A. H. S. Gillson, Dean of Arts and Science, wanted theoretical physicists to be in the Mathematics Department. He came with the dream of creating a theoretical physics group at McGill. By the spring of 1949, Phil was authorized to recruit two junior faculty in Mathematics. He hired Theodore (Ted) F. Morris from U. Toronto, who joined in September 1949, and me, who came in January 1950. The group had begun. Phil Wallace was born in Toronto in 1915 and grew up there. He entered the University of Toronto in 1933, earned a B.A. in mathematics in 1937, a M.A. in 1938, and a Ph.D. in applied mathematics in 1940 under Leopold Infeld. His Ph.D. thesis in general relativity was entitled 'On the relativistic equations of motion in electromagnetic theory.' In 1940 World War II had engulfed Europe and was having its effect on Canada, but the US was still at peace. L. J. Synge, Head of the Applied Mathematics Department at Toronto, told Wallace that people such as he would be needed in war work, but things were not ready quite yet. Hold yourself ready. Phil took a two-year position as lecturer in mathematics at the University of Cincinnati (1940-42); in the fall of 1942 he became a lecturer in mathematics at M.I.T. It was from there that he was recruited by Synge to join the war effort from 1943 to 1946 at N.R.C.'s Montreal Laboratory, the genesis of the Canadian Atomic Energy Project. Phil has described those heady wartime years in these pages. Much of the effort of the theoretical physicists was on nuclear reactor theory and the properties of relevant materials, such as graphite, under long and intense neutron bombardment. In late 1945 Phil was sent for four months to Bristol to learn about the properties of graphite from the esteemed N. F. Mott. This exposure led Phil to a life-long interest in

    A breakthrough has been discovered for controlling seismic sources to generate selectable low frequencies. Conventional seismic sources, including sparkers, rotary mechanical, hydraulic, air guns, and explosives, by their very nature produce high-frequencies. This is counter to the need for long signal transmission through rock. The patent pending SeismicPULSER{trademark} methodology has been developed for controlling otherwise high-frequency seismic sources to generate selectable low-frequency peak spectra applicable to many seismic applications. Specifically, we have demonstrated the application of a low-frequency sparker source which can be incorporated into a drill bit for Drill Bit Seismic While Drilling (SWD). To create the methodology of a controllable low-frequency sparker seismic source, it was necessary to learn how to maximize sparker efficiencies to couple to, and transmit through, rock with the study of sparker designs and mechanisms for (a) coupling the sparker-generated gas bubble expansion and contraction to the rock, (b) the effects of fluid properties and dynamics, (c) linear and non-linear acoustics, and (d) imparted force directionality. After extensive seismic modeling, the design of high-efficiency sparkers, laboratory high frequency sparker testing, and field tests were performed at the University of Texas Devine seismic test site. The conclusion of the field test was that extremely high power levels would be required to have the range required for deep, 15,000+ ft, high-temperature, high-pressure (HTHP) wells. Thereafter, more modeling and laboratory testing led to the discovery of a method to control a sparker that could generate low frequencies required for deep wells. The low frequency sparker was successfully tested at the Department of Energy Rocky Mountain Oilfield Test Center (DOE RMOTC) field test site in Casper, Wyoming. An 8-in diameter by 26-ft long SeismicPULSER{trademark} drill string tool was designed and manufactured by TII

  8. The wildgeographer avatar shows how to measure soil erosion rates by means of a rainfall simulator (United States)

    Cerdà, Artemi; González Pelayo, Óscar; Pereira, Paulo; Novara, Agata; Iserloh, Thomas; Prosdocimi, Massimo


    This contribution to the immersed worlds wish to develop the avatar that will teach the students and other scientists how to develop measurements of soil erosion, surface runoff and wetting fronts by means of simulated rainfall experiments. Rainfall simulation is a well established and knows methodology to measure the soil erosion rates and soil hydrology under controlled conditions (Cerdà 1998a; Cerdà, 1998b; Cerdà and Jurgensen, 2011; Dunkerley, 2012; Iserloh et al., 2012; Iserloh et al., 2013; Ziadat and Taimeh, 2013; Butzen et al., 2014). However, is a method that requires a long training and expertise to avoid mismanagement and mistaken. To use and avatar can help in the teaching of the technique and the dissemination of the findings. This contribution will show to other avatars how to develop an experiment with simulated rainfall and will help to take the right decision in the design of the experiments. Following the main parts of the experiments and measurements the Wildgeographer avatar must develop: 1. Determine the objectives and decide which rainfall intensity and distribution, and which plot size to be used. Choose between a laboratory or a field rainfall simulation. 2. Design of the rainfall simulator to achieve the objectives: type of rainfall simulator (sprayer or drop former) and calibrate. 3. The experiments are carried out. 4. The results are show.

  9. Landscape development, forest fires, and wilderness management. (United States)

    Wright, H E


    Both the landforms and the vegetation of the earth develop to states that are maintained in dynamic equilibrium. Short-term equilibrium of a hillslope or river valley results from intersection between erosional and depositional tendencies, controlled by gravitational force and the efficiency of the transporting medium. Long-term equilibrium of major landforms depends on crustal uplift and the resistance of the rock to weathering. In most parts of the world landscape evolves toward a peneplain, but the reduction rate approaches zero as the cycle progresses, and the counteracting force of crustal uplift intercedes before the end form is reached. Davis described this theoretical model in elegant terms. Leopold and Hack have provided a new and quantitative understanding of short-range geomorphic interactions that tend to discredit the Davisian model in the eyes of many. However, the substitute models of quasi-equilibrium or dynamic equilibrium merely describe short-range situations in which this or that Davisian stage is maintained despite uplift or downwasting. Given crustal stability and an unchanging climate, landforms would presumably still evolve through Davisian stages. However, the Davis model cannot be tested, for despite tremendous inventions in geochronology and impressive advances in stratigraphic knowledge, we cannot yet establish the rates or even the fact of crustal uplift in most areas. We are left with an unresolvable problem, for the sedimentary records of erosional history are largely inaccessible, undatable, and indecipherable, at least in the detail necessary to describe long-term evolution of the landscape. We know more about the evolution and maintenance of vegetation assemblages than about landform evolution, for even long-term vegetation sequences are within the scope of radiocarbon dating, and the biostratigraphic record is detailed. Even here, however, distinctions between short-term and long-term situations must be made, so that Clements

    competition tasks has been implemented at the University Ljubljana, Slovenia: in the final paper of the set, Gorazd Planinsic reports on the adoption of IYPT problems in introductory labs. 3. Outlook This collection of papers gives information about physics competitions and can provide physics teachers, in particular at university level, with ideas, examples and exercises to implement in their teaching. Since this combined presentation is a first for European Journal of Physics (and perhaps for other journals, at least to our knowledge), it would be very helpful to get feedback. In particular, we would be interested to receive answers to the following questions: Did you find these papers interesting and/or useful and should European Journal of Physics continue publishing annotated examples of physics competitions on an annual basis? Which parts were of special interest to you and which parts were not adequate or useful at all? Should we extend these projects including examples from other competitions (for example, the Olympiad on Astrophysics and Astronomy)? Do you know of other examples, where physics competitions were included in university teaching? If yes, please inform us and give references.
