Sample records for leopold casper 1859-1959

  1. [Urology and National Socialism illustrated by the example of Leopold Casper (1859-1959)]. (United States)

    Moll, F H; Rathert, P; Fangerau, H


    Leopold Casper (1859-1959) was one of the founders of the German Urological Society (DGfU) in 1906. He introduced functional kidney testing and a special cystoscope for ureteral catheterization. In 1913 he was president of the 4th congress held in the German capital Berlin. His textbook on genito-urinary diseases was translated by Charles W. Bonney in 1910 and proved the high quality of his scientific work. As a Jew he was forced to leave Nazi Germany later on in 1933 and from 1941 onwards he lived in New York. The anniversary of his 150th birthday should be remembered with special focus on the exodus of Jewish German scientists during the Nazi period.

  2. 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…

    Hartmann, Dennis L.

    Communicating the results of environmental science research to nonscientists was the focus of a week-long meeting of fellows of the Aldo Leopold Leadership Program (ALLP) in June. Participating were 20 mid-career university facultymembers, the first group of ALLP fellows to be selected.Discussions were held on the role of scientists in society, techniques for effective leadership, improving communications skills, and working productively with news media. The training program considers both print and broadcast media as well as other outreach vehicles. The meeting was held at Kah Nee Ta Resort on the Warm Springs Indian Reservation, Warm Springs, Oregon, June 15-21, 1999.

  5. 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.

  6. 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. 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. Molecular genetic investigations on Austria's patron saint Leopold III


    Bauer, Christiane Maria; Bodner, Martin; Niederst?tter, Harald; Niederwieser, Daniela; Huber, Gabriela; Hatzer-Grubwieser, Petra; Holubar, Karl; Parson, Walther


    The successful marriage policy of margrave Leopold III increased the importance of the House of Babenberg in late medieval Austria (12th century). Historical documentation is inconclusive in providing evidence whether or not his eldest son Adalbert derived from an earlier relationship or from the marriage with King Henry IV's daughter Agnes of Waiblingen, with whom Leopold is considered to have had 17 children. As a matter of fact Adalbert was ignored in the line of succession in favor of a y...

  10. 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.

  12. Molecular genetic investigations on Austria's patron saint Leopold III. (United States)

    Bauer, Christiane Maria; Bodner, Martin; Niederstätter, Harald; Niederwieser, Daniela; Huber, Gabriela; Hatzer-Grubwieser, Petra; Holubar, Karl; Parson, Walther


    The successful marriage policy of margrave Leopold III increased the importance of the House of Babenberg in late medieval Austria (12th century). Historical documentation is inconclusive in providing evidence whether or not his eldest son Adalbert derived from an earlier relationship or from the marriage with King Henry IV's daughter Agnes of Waiblingen, with whom Leopold is considered to have had 17 children. As a matter of fact Adalbert was ignored in the line of succession in favor of a younger brother, Leopold IV, which has led to long term historical discussions. Human remains attributed to these individuals were subjected to DNA analysis. Autosomal, Y-chromosomal and mitochondrial DNA analyses brought successful results, which suggested that Leopold III, Agnes and Adalbert were related in parent-son constellation, in contrast to historical considerations. A possible mix-up of Adalbert's remains with those of his younger brother Ernst could not be confirmed by DNA analysis. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  13. 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

  14. Communications Training Courses Across the Leopold Leadership Network (United States)

    Hayden, T.; Gerber, L. R.; Silver, W. L.


    For nearly fifteen years, the Leopold Leadership Program has provided science communication training and support to mid-career academic environmental researchers from across North America. There has been an emphasis throughout on effective communication to non-scientific audiences. Increasingly, Leopold fellows have been developing communications courses for their own students, responding to the need for future scientists to be able to communicate well with the public, the media, policy makers and other audiences. At a June 2012 reunion meeting, a group of past fellows and communications trainers conducted a curriculum exchange, sharing experiences and ideas for successful inclusion of communications training in environmental science curricula. This presentation will present case studies from several institutions, including the use of podcasting, web columns, social media, in-person presentation and other presentation styles for connecting general audiences. We will share best practices, challenges and recommendations for curriculum development and institutional acceptance.

  17. ["... 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.

  18. Risk management and the wisdom of Aldo Leopold. (United States)

    Warren, Julianne Lutz; Kieffer, Susan


    Human demands on nature have increased due to our burgeoning population. The applications of scientific knowledge to the development of increasingly powerful technologies and consumptive lifestyles by more and more people have created a modern category of human-caused disaster-stealth disasters. Stealth disasters-such as agriculturally-induced soil erosion and release of unprecedented amounts of greenhouse gases into Earth's atmosphere-tend to have protracted, unobvious onsets; do not necessarily have dramatic manifestations; and often do not attract public attention until they reach a stage approaching catastrophic consequences. At this late stage it is difficult or impossible to undo damage. Scientists tend to be among the first to understand the physical causes and notice the developments of stealth disasters and their risks and yet scientific knowledge is not enough to prevent or mitigate them. As we search for ways to deal with stealth disasters, the concept of "land health" assembled by the prominent conservationist and author, Aldo Leopold (1887-1948), can, in normative terms, provide an ecologically grounded example of nature in good condition toward which society can aim. Evidence of the reverse-symptoms of land illness-can provide a checklist for risk analysis and management that helps guide people away from harm-causing attitudes and activities and toward beneficial outcomes. Leopold's criteria of land health motivated by a land ethic that incorporates the whole of nature may be applied at geographic scales ranging from local to global as a framework for contemporary risk management.

  1. 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.

  4. 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

  6. [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.

  7. Framing a Philosophy of Environmental Action: Aldo Leopold, John Muir, and the Importance of Community (United States)

    Goralnik, Lissy; Nelson, Michael P.


    A philosophy of action consists of a theory about how and why we do things and what motivates us to act. By juxtaposing the theory of environmental action implied by the works and life of John Muir with the philosophy of action suggested by Aldo Leopold's Land Ethic, we will illuminate the importance of a philosophy of action in determining one's…

  9. CASPER: context-aware scheme for paired-end reads from high-throughput amplicon sequencing. (United States)

    Kwon, Sunyoung; Lee, Byunghan; Yoon, Sungroh


    Merging the forward and reverse reads from paired-end sequencing is a critical task that can significantly improve the performance of downstream tasks, such as genome assembly and mapping, by providing them with virtually elongated reads. However, due to the inherent limitations of most paired-end sequencers, the chance of observing erroneous bases grows rapidly as the end of a read is approached, which becomes a critical hurdle for accurately merging paired-end reads. Although there exist several sophisticated approaches to this problem, their performance in terms of quality of merging often remains unsatisfactory. To address this issue, here we present a context-aware scheme for paired-end reads (CASPER): a computational method to rapidly and robustly merge overlapping paired-end reads. Being particularly well suited to amplicon sequencing applications, CASPER is thoroughly tested with both simulated and real high-throughput amplicon sequencing data. According to our experimental results, CASPER significantly outperforms existing state-of-the art paired-end merging tools in terms of accuracy and robustness. CASPER also exploits the parallelism in the task of paired-end merging and effectively speeds up by multithreading. CASPER is freely available for academic use at

  10. 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?”

  11. Peta-Flop Real Time Radio Astronomy Signal Processing Instrumentation and the CASPER Collaboration (United States)

    Werthimer, Dan


    I will briefly describe next generation radio telescopes, such as HERA and the Square Kilometer Array (SKA), which will require 1E15 to 1E17 operations per second of real time processing. I'll present some of the new architectures we've used to develop a variety of heterogeneous FPGA-GPU-CPU based signal processing systems for such telescopes, including spectrometers, correlators, and beam formers. I will also describe the CASPER collaboration, which has developed architectures, open source programming tools, libraries and reference designs that make it relatively easy to develop a variety of scalable, upgradeable, fault tolerant, low power, real time digital signal processing instrumentation. CASPER utilizes commercial 10Gbit and 40 Gbit ethernet switches to interconnect open source general purpose field programmable gate array (FPGA) boards with GPUs and software modules. CASPER collaborators at hundreds of universities, government labs and observatories have used these techniques to rapidly develop and deploy a variety of correlators, beamformers, spectrometers, pulsar/transient machines, and VLBI instrumentation. CASPER instrumentation is also utilized in physics, medicine, genomics and engineering. Open source source hardware, software, libraries, tools, tutorials, reference designs, information about workshops, and how to join the collaboration are available at

  12. 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.

  13. 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.

  18. The cosmic axion spin precession experiment (CASPEr): a dark-matter search with nuclear magnetic resonance (United States)

    Garcon, Antoine; Aybas, Deniz; Blanchard, John W.; Centers, Gary; Figueroa, Nataniel L.; Graham, Peter W.; Kimball, Derek F. Jackson; Rajendran, Surjeet; Gil Sendra, Marina; Sushkov, Alexander O.; Trahms, Lutz; Wang, Tao; Wickenbrock, Arne; Wu, Teng; Budker, Dmitry


    The cosmic axion spin precession experiment (CASPEr) is a nuclear magnetic resonance experiment (NMR) seeking to detect axion and axion-like particles which could make up the dark matter present in the Universe. We review the predicted couplings of axions and axion-like particles with baryonic matter that enable their detection via NMR. We then describe two measurement schemes being implemented in CASPEr. The first method, presented in the original CASPEr proposal, consists of a resonant search via continuous-wave NMR spectroscopy. This method offers the highest sensitivity for frequencies ranging from a few Hz to hundreds of MHz, corresponding to masses {m}{{a}}∼ {10}-14–{10}-6 eV. Sub-Hz frequencies are typically difficult to probe with NMR due to the diminishing sensitivity of magnetometers in this region. To circumvent this limitation, we suggest new detection and data processing modalities. We describe a non-resonant frequency-modulation detection scheme, enabling searches from mHz to Hz frequencies ({m}{{a}}∼ {10}-17–{10}-14 eV), extending the detection bandwidth by three decades.

    Full Text Available Leopold Levy, a French painter who was invited to our county in the framework of the academic Reforms, worked as the head of painting department of the art academy between 1937 and 1949. Forty paintings of Leopold Levy, who assumed an important duty in a certain the period of Turkish art and art teaching, whose visual works are scarcely seen in the national literature, belonging to Ünal-Ceyda Göğüş collection painted between 1920 and 1966, were exhibited in the TUYAP 2014 24th international art fair artist. This paper is related to the general evaluation of the paintings in the exhibition. Levy, who worked for the establishment of the Arts and Sculpture museum upon the request of Atatürk played an important role in the acquisition of the art pieces of Bonnard, Derain, Marquet, Segonzea, Braque, Matisse and Dufy. He established the mosaics work shop in the academy and contributed to the enrichment of the art library and published so many Articles in various journal and news-papers, submitted Presentations in various conferences and opened individual exhibitions made a great Contribution for the development of the medium of art in Turkey and played an important role in the training of so many artists in Turkish painting.

    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 natural history museums and their purpose. A lecture given by Leopold von Buch (1774-1853) in April 1838]. (United States)

    Kröger, Björn


    A manuscript of a lecture by the Prussian geologist Leopold von Buch given at the Berlin Society of the Friends of the Humanity was discovered at the Museum für Naturkunde, Berlin. The text is a raw version of a passionate plea for the formation of natural history collections as science places, with a partly biting humor. Based on until now unknown anecdotes about naturalists like Kaspar Maria Graf Sternberg (1761-1838) and Friedrich Wilhelm Hoeninghaus (1771-1854) Leopold von Buch argues with von Sternberg for the scientific value of natural history collections. The repeating references to the works of Goethe and an extensive addendum of various Dante translations into German are striking. The lecture manuscript complements our knowledge about the thinking of this important geologist, and provides new insights into the science policy of his time.

    Full Text Available The presence of Indonesian women writers with the dominant discourse of the power of body, presenting the pros and cons that would not go over. Female body is the language of women that can be poured through the writing of literary works. Helene Cixous brought the spirit of "writing the body" to motivate women authors to express himself through written discourse, which so far has been dominated by men. Cixous spirit is also promoted by Dinar Rahayu appear in the novel Ode untuk Leopold Von Sacher-Masoch. Dinar Rahayu voicing complexity of urban women's voices in this novel through several migration symbolic of the power of the female body. Migration is enriched by the presence of symbolic power in a sound body of Greek and Scandinavian mythology and Leopold voices in his work Venus in Furs. Through in-depth reading on the symbolic migration brought to the Ode untuk Leopold Von Sacher-Masoch through the voices of the characters and the particularities of naration techniques can be seen that this novel (as well as other sexist novels is not merely a commodity that exploit sexuality pornography but rather an attempt to author urban female voices will be the "body power". This study uses content analysis method that begins with the reading of literature, heuristic and hermeneutic, and take advantage of intertextuality approach.

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

    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.

  5. 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.

  6. 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.

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

    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.

  9. Evaluation of (fli:GFP) Casper Zebrafish Embryos as a Model for Human Conjunctival Melanoma. (United States)

    Pontes, Kelly Cristine de Sousa; Groenewoud, Arwin; Cao, Jinfeng; Ataide, Livia Maria Silva; Snaar-Jagalska, Ewa; Jager, Martine J


    Conjunctival melanoma (CM) is a rare malignant disease that can lead to recurrences and metastases. There is a lack of effective treatments for the metastases, and we set out to develop a new animal model to test potential therapies. Zebrafish are being used as a model for many diseases, and our goal was to test whether this animal could be used to study CM. Three human CM cell lines (CRMM-1 and CM2005.1, which both harbor a B-RAF mutation, and CRMM-2, which has an N-RAS mutation) were injected into the yolk sac, around the eye, and into the duct of Cuvier of transgenic (fli:GFP) Casper zebrafish embryos. Fluorescent and confocal images were taken to assess the phenotype and the behavior of engrafted cells and to test the effect of Vemurafenib as a treatment against CM. While the cells that had been injected inside the yolk sac died and those injected around the eye sporadically went into the circulation, the cells that had been injected into the duct of Cuvier colonized the zebrafish: cells from all three cell lines proliferated and disseminated to the eyes, where they formed clusters, and to the tail, where we noticed extravasation and micrometastases. Vemurafenib, a potent agent for treatment of B-RAF V600E-positive melanoma, inhibited outgrowth of CRMM-1 and CM2005.1 cells in a mutation-dependent way. The (fli:GFP) Casper zebrafish embryo can be used as an efficient animal model to study metastatic behavior of human CM cells and warrants further testing of drug efficacy to aid care of CM patients.

  10. 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

  11. 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.

  12. Developing a CASPER Survey to Assess the Prevalence of Risk Factors for Neglected Tropical Diseases in Texas. (United States)

    Smitherman, Seth; Hammond, Tracy; Goldberg, Daniel; Horney, Jennifer

    While more than a billion people live at risk of neglected tropical diseases in areas of Asia, sub-Saharan Africa, and Latin America, the degree to which such diseases burden countries like the United States is currently unclear. Even though many neglected tropical diseases such as dengue, leishmaniasis, and Chagas disease are not endemic to the United States, the possibility of their emergence is noteworthy, especially in states like Texas, which has high levels of poverty, a large immigrant population, and a climate amenable to the vectors for these diseases and is geographically proximate to endemic areas. Despite the health threat that emerging neglected tropical diseases may pose, little is known about the prevalence of risk factors for them in the United States. Texas House Bill 2055, enacted on September 1, 2015, mandated the establishment of a surveillance program for neglected tropical diseases in Texas. After reviewing the potential risk factors for transmission in Texas, we developed a 41-question survey that could be implemented using the Community Assessment for Public Health Emergency Response (CASPER) method. In concert with public health surveillance and vector population monitoring, data from CASPERs could be used to quickly and cost-effectively assess the prevalence of risk factors for 10 neglected tropical diseases in Texas or elsewhere in the United States. The data generated by future CASPERs conducted using this survey could be immediately actionable, guiding public health priority setting and decision making.

  13. Computer-assisted detection of monoclonal components: results from the multicenter study for the evaluation of CASPER (Computer Assisted Serum Protein Electrophoresis Recognizer) algorithm. (United States)

    To investigate the potential use of Artificial Neural Network (ANN) in the evaluation of serum protein electrophoresis, we set up a multicenter study involving six Italian laboratories. For this purpose, we developed an algorithm named CASPER (Computer Assisted Serum Protein Electrophoresis Recognizer). A total of 59,516 samples from the six centers were divided into three groups. Training and validation sets were used to develop the neural network, whereas evaluation set was used to test the performance of CASPER in recognizing abnormal electrophoretic profiles. CASPER showed 93.0% sensitivity and 47.4% specificity. CASPER sensitivity and specificity ranged in the six sites from 88% (site 3) to 97% (site 5) and from 36% (site 6) to 53% (site 3), respectively. Sensitivity for gamma zone was 94.6%, for beta zone 89.7% and for oligoclonal patterns 92.0%. The sensitivity of the CASPER algorithm does not allow us to recommend its use as a replacement for the visual inspection, but it could be helpful in avoiding accidental misclassifications by the operator. Moreover, the CASPER algorithm may be a useful tool for training operators and students. This study evidenced a high inter-observer variability, which should be addressed in a dedicated study. Data set to train and validate ANNs should contain a huge range and an adequate number of different abnormalities.

  15. Experiences with the Design and Construction of Astronomical Instrumentation using CASPER: The Digital Backend System (United States)

    Prestage, Richard M.; Bloss, M.; Brandt, J.; Creager, R.; Demorest, P.; Ford, J.; Jones, G.; Luo, J.; McCullough, R.; Ransom, S. M.; Ray, J.; Watts, G.; Whitehead, M.


    NRAO recently designed and built a state-of-the-art backend system for the Shanghai Astronomical Observatory's (SHAO) 65 meter radio telescope. The machine, called the Digital Backend System (DIBAS), was created from the design of the VErsatile GBT Astronomical Spectrometer (VEGAS) by adding nine incoherent pulsar search modes and eight coherent dedispersion timing modes to complement the 29 VEGAS spectral line modes. Together these modes cover all of the anticipated science requirements for the 65 meter except for VLBI. The VEGAS multi-beam spectrometer was recently designed and built for the Green Bank Telescope (GBT) through a partnership between the National Radio Astronomy Observatory (NRAO) and the University of California at Berkeley. The VEGAS spectrometer is based on a Field Programmable Gate Array (FPGA) frontend and a heterogeneous computing backend comprised of Graphical Processing Units (GPUs) and x86-64 CPUs. Working together, the hardware in this system provides processing power to analyze up to 8 dual-polarization or 16 single-polarization inputs, at bandwidths of up to 1.25 GHz per input. An aggregate of up to 10 GHz of bandwidth, dual polarization, may be simultaneously processed with the VEGAS spectrometer. As capable as this spectrometer is, it has no advanced pulsar capabilities such as were needed for DIBAS. To create DIBAS, VEGAS was augmented with new FPGA designs based on those built for the Green Bank Ultimate Pulsar Processing Instrument (GUPPI) some five years ago. GUPPI was built on earlier generations of FPGA hardware designed by the CASPER project at Berkeley. Porting the old GUPPI designs to modern hardware and wider bandwidths was a good test case to determine the portability of the FPGA designs and the utility of the toolset to help move designs between generations of FPGA chips, as well as the degree of reuse that could be obtained from the VEGAS project. This paper will explore the unique aspects of the DIBAS project, including

  18. 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.

    Full Text Available Prince Baltasar Carlos’s death in 1646 turned his little sister, María Teresa, into the direct heiress of King Felipe IV of Spain. For this reason, her marriage became a key issue regarding the European politics of the central decades of the seventeenth century. Her marriage with the heir of Emperor Ferdinand III was the option chosen by Felipe IV as the most convenient for his territories as long as there was no male heir for his throne. But the negotiations to achieve that end were far from easy. In this essay, we will examine the negotiations conducted between Madrid and Vienna during the years 1654 and 1657, to arrange the marriage between Infanta María Teresa and the future emperor Leopold I, through the correspondence interchanged between King Felipe IV and his ambassadors in the imperial court..

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.

    Full Text Available The Prince Léopold Institute for tropical medicine in Antwerp: an overview The struggle against the sleeping sickness in Congo was the major reason for the opening of a School of Tropical Medicine (1906. The edition of new statutes in 1931 at the moment of the transfer to Antwerp conformed the autonomous and neutral character of the Institute. On the other hand, as the person responsible to the community represented by the Ministry of Colonies and – later – the Ministry of Education, she had to publish an annual report on their activities and finances. After the independence of the colony (1960 the teaching and research policy accentuated development aid, and in particular the fight against tropical disease (malaria, sleeping sickness, leishmaniasis ... and HIV (AIDS and Tuberculosis. The Institute delivers postgraduate and master's degrees. Each year, two hundred doctors and nurses attend its classes, and around a hundred students from over the world prepare for their medical degree. The Institute of Tropical Medicine in Antwerp is a ‘center of excellence’ and an important component in an international network that aims for ‘Health for All’.

  15. Cyclic and Macrocyclic Organic Compounds - a Personal Review in Honor of Professor Leopold Ružička

    Directory of Open Access Journals (Sweden)

    Höcker¸, H.


    Full Text Available Ružička opened the field of cyclic molecules such as cyclic terpenes and cyclic ketones with up to 17 ring atoms. This work until now was extended in many directions such as cyclic paraffins, crown ethers and cryptands and cyclic ester amides. Cyclic molecules are formed upon electron transfer and intramolecular association of polymers with two active ends and they are synthesized by directed cyclization of bifunctional macromolecules. In the course of step growth polymerization and ring opening polymerization, ring chain equilibria may be established; the larger the monomer unit the easier is the separation of pure oligomers such as the heptamer of cyclododecene with 84 carbon atoms in the ring. Still many questions remain open, in particular whether there are macrocyclic catenanes in commercial polycondensates.

  16. 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.

    Full Text Available Ao definir-se como um quarto de espelhos fantásticos, Fernando Pessoa encontra no espelho a única certeza comum a todas as “reflexões falsas”, a materialização da “única anterior realidade” que os seus inúmeros espelhos “torcem”. Tomando a Branca de Neve como uma sublimação final da beleza usurpadora da Madrasta e a corporização de uma beleza inicial, considerarei os “inúmeros espelhos fantásticos” de Pessoa e o “cracked looking glass” de Joyce como distorcidas sequelas de uma qualquer pureza de origem ou de uma superfície reflectora una. Argumento que Caeiro, Bloom, o Império Espiritual de Pessoa e a “Irlanda Caricatura do Mundo Sério” de Joyce virão a ser a materialização dessa superfície reflectora de origem, Brancas de Neve posteriores às realidades que lhes são madrastas mas colocadas estrategicamente na sua origem e destinadas a suprir a ausência de uma “única anterior realidade” – pessoal, nacional e global.

    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.

  7. 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.

    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.

  18. 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.

  1. 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.

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.

    Northern fulmars from two breeding colonies in the Canadian Arctic, Cape Vera and Prince Leopold Island, were analyzed for organochlorine pesticides, PCBs, perfluorinated compounds (PFCs) and total mercury (Hg). Hepatic concentrations of organochlorines and Hg were highest in the male fulmars from Cape Vera. Perfluorooctane sulfonate (PFOS) concentrations did not vary significantly between sexes or colonies. However, concentrations of the perfluorinated carboxylates (PFCAs) were higher in fulmars from Cape Vera than Prince Leopold Island. The C{sub 11}-C{sub 15} PFCAs averaged 90% of the PFCA profile at both colonies. Polychorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and non-ortho PCBs (NO-PCBs) were measured only in birds from Prince Leopold Island. Concentrations of PCDDs, PCDFs, NO-PCBs and Toxic Equivalents (TEQs) did not differ significantly between sexes. {Sigma}TEQ was comprised mainly of {Sigma}TEQ{sub PCDF}. Concentrations of Hg and the persistent halogenated compounds reported in this study were below published toxicological threshold values for wild birds. - Northern fulmars in the Canadian Arctic demonstrate sex-specific, colony-specific, and regional differences in contaminant profiles.

  11. 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.

  12. 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.

  13. Application of spin-exchange relaxation-free magnetometry to the Cosmic Axion Spin Precession Experiment (United States)

    Wang, Tao; Kimball, Derek F. Jackson; Sushkov, Alexander O.; Aybas, Deniz; Blanchard, John W.; Centers, Gary; Kelley, Sean R. O.'; Wickenbrock, Arne; Fang, Jiancheng; Budker, Dmitry


    The Cosmic Axion Spin Precession Experiment (CASPEr) seeks to measure oscillating torques on nuclear spins caused by axion or axion-like-particle (ALP) dark matter via nuclear magnetic resonance (NMR) techniques. A sample spin-polarized along a leading magnetic field experiences a resonance when the Larmor frequency matches the axion/ALP Compton frequency, generating precessing transverse nuclear magnetization. Here we demonstrate a Spin-Exchange Relaxation-Free (SERF) magnetometer with sensitivity ≈ 1 fT /√{ Hz } and an effective sensing volume of 0.1 cm3 that may be useful for NMR detection in CASPEr. A potential drawback of SERF-magnetometer-based NMR detection is the SERF's limited dynamic range. Use of a magnetic flux transformer to suppress the leading magnetic field is considered as a potential method to expand the SERF's dynamic range in order to probe higher axion/ALP Compton frequencies.

  1. Launching GUPPI: the Green Bank Ultimate Pulsar Processing Instrument (United States)

    DuPlain, Ron; Ransom, Scott; Demorest, Paul; Brandt, Patrick; Ford, John; Shelton, Amy L.


    The National Radio Astronomy Observatory (NRAO) is launching the Green Bank Ultimate Pulsar Processing Instrument (GUPPI), a prototype flexible digital signal processor designed for pulsar observations with the Robert C. Byrd Green Bank Telescope (GBT). GUPPI uses field programmable gate array (FPGA) hardware and design tools developed by the Center for Astronomy Signal Processing and Electronics Research (CASPER) at the University of California, Berkeley. The NRAO has been concurrently developing GUPPI software and hardware using minimal software resources. The software handles instrument monitor and control, data acquisition, and hardware interfacing. GUPPI is currently an expert-only spectrometer, but supports future integration with the full GBT production system. The NRAO was able to take advantage of the unique flexibility of the CASPER FPGA hardware platform, develop hardware and software in parallel, and build a suite of software tools for monitoring, controlling, and acquiring data with a new instrument over a short timeline of just a few months. The NRAO interacts regularly with CASPER and its users, and GUPPI stands as an example of what reconfigurable computing and open-source development can do for radio astronomy. GUPPI is modular for portability, and the NRAO provides the results of development as an open-source resource.

  2. In vivo cell tracking and quantification method in adult zebrafish (United States)

    Zhang, Li; Alt, Clemens; Li, Pulin; White, Richard M.; Zon, Leonard I.; Wei, Xunbin; Lin, Charles P.


    Zebrafish have become a powerful vertebrate model organism for drug discovery, cancer and stem cell research. A recently developed transparent adult zebrafish using double pigmentation mutant, called casper, provide unparalleled imaging power in in vivo longitudinal analysis of biological processes at an anatomic resolution not readily achievable in murine or other systems. In this paper we introduce an optical method for simultaneous visualization and cell quantification, which combines the laser scanning confocal microscopy (LSCM) and the in vivo flow cytometry (IVFC). The system is designed specifically for non-invasive tracking of both stationary and circulating cells in adult zebrafish casper, under physiological conditions in the same fish over time. The confocal imaging part in this system serves the dual purposes of imaging fish tissue microstructure and a 3D navigation tool to locate a suitable vessel for circulating cell counting. The multi-color, multi-channel instrument allows the detection of multiple cell populations or different tissues or organs simultaneously. We demonstrate initial testing of this novel instrument by imaging vasculature and tracking circulating cells in CD41: GFP/Gata1: DsRed transgenic casper fish whose thrombocytes/erythrocytes express the green and red fluorescent proteins. Circulating fluorescent cell incidents were recorded and counted repeatedly over time and in different types of vessels. Great application opportunities in cancer and stem cell researches are discussed.

  3. Powstanie i rozwój filozofii środowiskowej w USA na podstawie poglądów Johna Muira, Aldo Leopolda i J. Bairda Callicota

    Directory of Open Access Journals (Sweden)

    Leszek Pyra


    Full Text Available The Origin and Development of Environmental Philosophy in the US according to John Muir, Aldo Leopold and J. Baird Callicot. The publication refers to environmental philosophy, which is also called ecological philosophy or ecophilosophy. It shows in what way philosophical reflection on the environment has been shaped in the American tradition. In this context, the views of the thinkers listed below have been presented, analysed and evaluated. John Muir, an astute observer of wild nature, has been presented as an enthusiast and a prophet persuading a return to nature. Muir was a forester under the strong influence of the representatives of transcendentalism. As an activist, he founded national parks that served to preserve virgin areas, and as a writer he popularized the concept of the preservation of wild areas. For many representatives of ecophilosophy, the views of Aldo Leopold, as expressed in his well-known work, A Sand County Almanac, constituted a new pattern of thinking about wild nature. The book itself is almost generally regarded as a bible of environmental philosophy. Leopold, a forester interested in philosophy, created the fundamentals of holistic environmental philosophy, but the theory he developed is not without defects, to which some attention has been paid in this paper. The theory of J. Baird Callicot presents the attitude of an academic philosopher with regard to wild nature. His attitude is fully professional as regards the applied method, thus allowing the author to avoid committing a naturalistic fallacy. Callicot reinterprets the issues of facts and values, because he thinks that the discoveries of the dynamically developing ecology make possible the reformulation of the traditional approach to such issues by utilising a spirit of acceptance, and lead to a shift from is to ought to be

  5. 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.

    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.

  11. Criticism of the Pap Smear as a Diagnostic Tool in Cervical Cancer Screening. (United States)

    Schneider, Volker


    This editorial by Dr. Leopold G. Koss appeared in the January 1980 issue of Acta Cytologica. It addressed recent critical opinions in the general media on cervical screening and its costs. It marked the beginning of a more critical approach to cytology by the lay press, health care providers, and epidemiologists. It was also the first of a series of highly informative editorials by Dr. Koss that illustrated the critical issues of cytology during the 1980s. The elegance and clarity of his articles reflect the high standard of editorial writing in Acta Cytologica at this time. These articles are reviewed and excerpts are presented. © 2017 S.

  12. Interrelationship of ecological science and environmental ethics

    Energy Technology Data Exchange (ETDEWEB)

    Marietta, D.E. Jr.

    A recent trend among environmentalists (e.g., Aldo Leopold) of basing ethical norms for land use, resource management and conservation on eological principles such as homeostasis is examined. Justification for such an ethical approach through analysis of moral judgment in explored and argued to be as sound as more traditional approaches. Issues such as the is/ought impasse, the connection between value judgements are definitive and categorical are treated as they relate to an ecological ethic, i.e., an environmental ethic grounded in ecological science. 33 references.

  15. [The physician and cosmetics--distorted images reflected in German medical historiography]. (United States)

    Sander, Sabine


    Physicians have been experts in cosmetics for thousands of years. Especially since the early modern period they have produced medical advice literature that included the topic of cosmetics for a general readership. Medical historians have paid scant attention to this aspect of doctors' activities, and when they did, this happened partly in a rather prejudiced manner, resulting in long-lasting misjudgements. This is illustrated with special reference to the case of the Berlin doctor and medical historian Julius Leopold Pagel (1851-1912).

  18. 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.

  19. 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.

  20. 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.

  1. Use of a highly transparent zebrafish mutant for investigations in the development of the vertebrate auditory system (Conference Presentation) (United States)

    Wisniowiecki, Anna M.; Mattison, Scott P.; Kim, Sangmin; Riley, Bruce; Applegate, Brian E.


    Zebrafish, an auditory specialist among fish, offer analogous auditory structures to vertebrates and is a model for hearing and deafness in vertebrates, including humans. Nevertheless, many questions remain on the basic mechanics of the auditory pathway. Phase-sensitive Optical Coherence Tomography has been proven as valuable technique for functional vibrometric measurements in the murine ear. Such measurements are key to building a complete understanding of auditory mechanics. The application of such techniques in the zebrafish is impeded by the high level of pigmentation, which develops superior to the transverse plane and envelops the auditory system superficially. A zebrafish double mutant for nacre and roy (mitfa-/- ;roya-/- [casper]), which exhibits defects for neural-crest derived melanocytes and iridophores, at all stages of development, is pursued to improve image quality and sensitivity for functional imaging. So far our investigations with the casper mutants have enabled the identification of the specialized hearing organs, fluid-filled canal connecting the ears, and sub-structures of the semicircular canals. In our previous work with wild-type zebrafish, we were only able to identify and observe stimulated vibration of the largest structures, specifically the anterior swim bladder and tripus ossicle, even among small, larval specimen, with fully developed inner ears. In conclusion, this genetic mutant will enable the study of the dynamics of the zebrafish ear from the early larval stages all the way into adulthood.

  2. 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.

  3. 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.

  4. Transforming sexuality: the medical sources of Karl Heinrich Ulrichs (1825-95) and the origins of the theory of bisexuality. (United States)

    Brooks, Ross


    This article explores the medical references in the writings of the German jurist and activist Karl Heinrich Ulrichs as a means of breaking new ground in diverse fields (including history of medicine, history of sexuality, and gender history). It demonstrates that the theory of bisexuality has a much deeper and more textured genealogy than has been hitherto appreciated and that dual-gendered bodies and minds must be better recognized as important through the nineteenth century. Specifically, it demonstrates that classifications and rhetoric of hermaphroditism, and other dual-gendered categories (e.g., sexual dualism and anatomical bisexuality), were deployed in diverse contexts through the period, often with little or no reference to the occurrence of genital ambiguities. Important discourses in embryology, utilized by Ulrichs, suggested that all individuals, in the earliest stages of fetal development, were hermaphroditic. In making an analogy among the ontogeny of sex anatomy, hermaphroditism, and the development of erotic preferences, Ulrichs sought to naturalize homoeroticism, rendering social and legal prohibitions untenable. His advocacy, however, was counterbalanced by the Prussian forensic expert Johann Ludwig Casper who had made some conceptual maneuvers similar to Ulrichs only couched in the rhetoric of pathology. Ulrichs was equivocal in his use of forensic works such as Casper's, condemning their authors but recognizing similarities with his own gender schema.

  5. Light Gas Gun Testing of PVDF by Undergraduates (United States)

    Hyde, Truell; Matthews, Lorin; Carmona-Reyes, Jorge

    Orbital debris has been a problem for spacecraft in orbit about the earth since the dawn of the space age. As such, a vital part of the launch preparation process for any space mission includes development of computer models, space debris tracking devices, in-situ dust detectors, and research into advanced shielding processes. It is necessary to reproduce the space environment in the lab in order to fully understand the physics behind the damage that space debris can cause. To this end, the Center for Astrophysics, Space Physics and Engineering Research (CASPER) employs a one-stage Light Gas Gun (LGG) for low velocity impact studies. This instrument has proven to be an ideal environment for introducing undergraduates to an experimental lab setting as well as to the field of orbital debris. This paper will discuss the advantages of including undergraduates in the lab early in their career. Recent data collected by undergraduates and technical interns using the CASPER LGG to determine the basic capabilities of Polyvinylidene Difluoride (PVDF) as an in-situ dust detector device will be examined. This type of device was chosen in part because it can easily be assembled and monitored by undergraduate students. Long-term educational goals of the project will also be discussed.

  8. Avaliação dos impactos ambientais aplicada aos resíduos sólidos do setor de pintura de uma indústria de equipamentos petrolíferos

    Directory of Open Access Journals (Sweden)

    Paolo dos Santos Campos


    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.

  9. 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.

  10. 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

  11. 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.

  12. Making Culture Bloom

    Directory of Open Access Journals (Sweden)

    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.

  13. 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

  14. Prolegomena to conservation: a fisheye review

    Energy Technology Data Exchange (ETDEWEB)

    Kury, C.


    Philosophies and attitudes toward conservation, such as the views of Walter Firey, Aldo Leopold, Gifford Pinchot, and others are examined and found to have merit, not as sole guides to environmental decisions, but as a framework for analyzing complex resource issues and arriving at rational policies. Objective definitions of conservation are often incomplete, as in the case of Smokey the Bear, who persuaded Americans that forest fires are bad and overlooked their benefits. Conservation is defined, not as a message, but as a permanent medium for optimizing social well-being by reconciling desires and needs in a rational way. A summary of current literature compares and evaluates the different perceptions of conservation as it applies to resource use and development. (DCK)

  15. The power and the glory: a spiritual connection with energy can save us in many ways

    Energy Technology Data Exchange (ETDEWEB)

    Bede Scharper, Stephen


    This article reviews energy issues from the point of view of the harmony existing between human beings, the land, and the cosmos. One docent, Aldo Leopold, reflects that the soil of Earth is an energy circuit which grounds much of life. It is a fountain of energy flowing through a network of soils, plants and animals. He calls on us to cultivate, Love, respect and admiration, for the energy of the land. Another docent, named Thomas Berry, takes a more holistic view in understanding energy within the larger universe. The devastation wrought by human beings is negating the billions of years of past development on the Earth. To find alternative energies has been a psychological and spiritual quest to advance our relationship with Earth. Berry asks us to work with, rather than against, the life-giving energies of the Earth.

  16. 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.

  17. 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.

  18. Generalized functional formulation for multi-fractal representation of basin hydraulic geometry (United States)

    Kim, JongChun; Paik, Kyungrock


    Natural rivers exhibit power-functional variability in their width, depth, and velocity with flow discharge (Leopold and Maddock, 1953). This relation named hydraulic geometry has been empirically supported by many field studies across the world (e.g., Leopold et al., 1964; Stall and Fok, 1968). The relationship appears either at a fixed cross-section, showing temporal variability, or along a downstream direction across an entire basin, showing spatial variability, the latter named downstream or basin hydraulic geometry. Theoretical studies that attempt to explain the power-law phenomenon (fractal), have assumed that the watershed is homogeneous hydrologically and geologically. Nevertheless, real watersheds are often subject to spatially heterogeneous conditions, due to various reasons including partial area storm coverage (Sólyom and Tucker, 2004) and transmission losses on bed and banks (Lane et al., 1997). In this setting, hydraulic geometry relationships are likely to deviate from monotonic power-law relationship and to follow rather more complex multi-fractal characteristics. In fact, deviation from single power-law was reported for at-a-station relationship of midwest rivers in US (Dodov and Foufoula-Georgiou, 2004). In the case of downstream variation, we identify significant multi-fractal characteristics over the Colorado River basin where strong heterogeneity in geological and hydrological settings presents. Conventional power-law hydraulic geometry relationships cannot express the functional variability for these cases. Motivated by this fact, we generalize the hydraulic geometry functional formulation in this study to express multi-fractal relationships. To do so, we couple the formulation of Paik and Kumar (2004), which generalized at-a-station and downstream relationships, with the formulation of Dodov and Foufoula-Georgiou (2004) which was proposed for multi-scaling in at-a-station relationship. The proposed formulation is successfully evaluated with

  19. Divining and Knowing: (United States)

    Stein, Claudia


    Summary This article investigates the historical method of Karl Sudhoff (1853– 1938), Germany’s first professor of medical history. It argues that in order to understand his ideas more fully, we need to step outside the historiography of medical history and assess his methodology in relation to the norms and ideals of German academic history writing in general. The article demonstrates that the philology-based “critical method” of Leopold von Ranke (1795–1886) was central to Sudhoff’s methodological thinking. It investigates the underlying philosophical and epistemological assumptions of Ranke’s method, which tend to be less appreciated than his overt empiricism and explores how Sudhoff applied these to the new professionalizing subdiscipline of the history of medicine. The article argues that Sudhoff’s concerns with the methodology of history, which involved a particular conception of the relationship between the human sciences and the medical sciences, offers compelling addresses to our times.

    Edwards, Harold M


    In his new undergraduate textbook, Harold M Edwards proposes a radically new and thoroughly algorithmic approach to linear algebra Originally inspired by the constructive philosophy of mathematics championed in the 19th century by Leopold Kronecker, the approach is well suited to students in the computer-dominated late 20th century Each proof is an algorithm described in English that can be translated into the computer language the class is using and put to work solving problems and generating new examples, making the study of linear algebra a truly interactive experience Designed for a one-semester course, this text adopts an algorithmic approach to linear algebra giving the student many examples to work through and copious exercises to test their skills and extend their knowledge of the subject Students at all levels will find much interactive instruction in this text while teachers will find stimulating examples and methods of approach to the subject

  1. The game of Double-Silver on intervals

    Gerald A. Heuer


    Full Text Available Silverman's game on intervals was analyzed in a special case by Evans, and later more extensively by Heuer and Leopold-Wildburger, who found that optimal strategies exist (and gave them quite generally when the intervals have no endpoints in common. They exist in about half the parameter plane when the intervals have a left endpoint or a right endpoint, but not both, in common, and (as Evans had earlier found exist only on a set of measure zero in this plane if the intervals are identical. The game of Double-Silver, where each player has its own threshold and penalty, is examined. There are several combinations of conditions on relative placement of the intervals, the thresholds and penalties under which optimal strategies exist and are found. The indications are that in the other cases no optimal strategies exist.

    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.

  3. 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.

  5. Situating trends in environmental education within the ecological debate

    Energy Technology Data Exchange (ETDEWEB)

    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 Ethic[close 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.

  6. 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

    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.

  10. Vertical mixing and elements of mesoscale dynamics over North Carolina shelf and contiguous Gulf Stream waters (United States)

    Lozovatsky, Iossif; Planella-Morato, Jesus; Shearman, Kipp; Wang, Qing; Fernando, Harindra Joseph S.


    Results of microstructure measurements conducted in October-November of 2015 as a part of the Coupled Air Sea Processes and Electromagnetic Ducting Research (CASPER) project are discussed. The measurements were taken on the North Carolina shelf and across the Gulf Stream front. On the shelf, the oceanic stratification was influenced by highly variable surface salinity and along-bottom advection. Vertical mixing was mostly governed by variable winds. The vertical eddy diffusivity was estimated using the VMP-based dissipation measurements, and the diffusivity values obtained during calm periods and stormy winds were compared. Parameterization of the diffusivity for various mesoscale dynamical conditions is discussed in terms of shear instabilities and internal wave-generated turbulence based on data obtained in deep waters of the Gulf Stream and on the continental slope.

    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

    Bryans, P.; Hannigan, J. W.; Sewell, S. D.; Judge, P. G.


    The spectral emission of the infrared solar corona is the most promising direct diagnostic of the coronal magnetic field, and yet remains poorly measured. During the 2017 total solar eclipse, we will perform the first spectral survey of the IR corona using the NCAR Airborne Interferometer. This Fourier Transform Infrared Spectrometer is configured to observe the coronal spectrum from 1.5 to 5.5 microns at R 10,000 from a ground-based site. The location is atop Casper Mountain, Wyoming (42.73ºN, 106.32ºW, 2400 masl), 8 km from the center-line of totality. In this presentation, we will outline the need for such measurements, describe the instrument design and adaptation for the eclipse measurement, observation scheme, and present preliminary results. We will also discuss implications for observing infrared coronal lines from the ground, for example with the upcoming DKIST facility.

    International Nuclear Information System (INIS)


    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

    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

    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.

  20. Warm layer and cool skin corrections for bulk water temperature measurements for air-sea interaction studies (United States)

    Alappattu, Denny P.; Wang, Qing; Yamaguchi, Ryan; Lind, Richard J.; Reynolds, Mike; Christman, Adam J.


    The sea surface temperature (SST) relevant to air-sea interaction studies is the temperature immediately adjacent to the air, referred to as skin SST. Generally, SST measurements from ships and buoys are taken at depths varies from several centimeters to 5 m below the surface. These measurements, known as bulk SST, can differ from skin SST up to O(1°C). Shipboard bulk and skin SST measurements were made during the Coupled Air-Sea Processes and Electromagnetic ducting Research east coast field campaign (CASPER-East). An Infrared SST Autonomous Radiometer (ISAR) recorded skin SST, while R/V Sharp's Surface Mapping System (SMS) provided bulk SST from 1 m water depth. Since the ISAR is sensitive to sea spray and rain, missing skin SST data occurred in these conditions. However, SMS measurement is less affected by adverse weather and provided continuous bulk SST measurements. It is desirable to correct the bulk SST to obtain a good representation of the skin SST, which is the objective of this research. Bulk-skin SST difference has been examined with respect to meteorological factors associated with cool skin and diurnal warm layers. Strong influences of wind speed, diurnal effects, and net longwave radiation flux on temperature difference are noticed. A three-step scheme is established to correct for wind effect, diurnal variability, and then for dependency on net longwave radiation flux. Scheme is tested and compared to existing correction schemes. This method is able to effectively compensate for multiple factors acting to modify bulk SST measurements over the range of conditions experienced during CASPER-East.

  1. Assessing the Prevalence of Risk Factors for Neglected Tropical Diseases in Brazos County, Texas. (United States)

    Horney, Jennifer; Goldberg, Daniel; Hammond, Tracy; Stone, Kahler; Smitherman, Seth


    Although more than one billion people live at risk of neglected tropical diseases (NTDs) in areas of Asia, sub-Saharan Africa, and Latin America, the degree to which they burden countries like the U.S. is unclear. Even though many NTDs such as dengue, leishmaniasis, and Chagas disease are typically not endemic to the U.S., the possibility of their emergence is noteworthy, especially in states like Texas with high levels of poverty, large immigrant populations, geographic proximity to endemic areas, and a climate amenable to the vectors for these diseases. Despite the health threat that emerging NTDs may pose, little is known about the prevalence of risk factors for NTDs in the U.S. We tested the Community Assessment for Public Health Emergency Response (CASPER) method to assess the prevalence of risk factors for NTDs in Brazos County, Texas.Results: We found relatively low prevalence of risk factors related to travel (5.2% of respondents visited an endemic area in the previous 3 months); however, few respondents reported adherence to mosquito prevention, such as wearing long sleeves and long pants (14.1%, 95% CI: 13.9,14.4) and repellant containing DEET (13.5%, 95% CI: 13.2,13.7). Between 5.4% and 35.8% of respondents had a visible container (e.g., pet water dishes, flower pots, bird baths) that could support mosquito breeding. CASPER findings present public health authorities with potential avenues for implementing health education and other interventions aimed at reducing exposure to risk factors for NTDs among Texas residents.

  3. Effects of a flood pulse on exchange flows along a sinuous stream (United States)

    Käser, D.; Brunner, P.; Renard, P.; Perrochet, P.; Schirmer, M.; Hunkeler, D.


    Flood pulses are important events for river ecosystems: they create hydrological interactions at the terrestrial/aquatic interface that fuel biological productivity and shape the hyporheic-riparian habitats. For example, floods promote faunal activity and decomposition by increasing the supply of oxygenated water in downwelling areas, while the following recession periods tend to provide stable thermal conditions favoured by fish or insects in areas of groundwater upwelling. This 3-D modelling study investigates the effect of stream stage transience (with events characterised by their intensity and duration) on hydrological exchanges between the surface and the near-stream subsurface. It evaluates, in particular, its effect on streams of varying sinuosity by quantifying the dynamic response of: (1) subsurface flow paths, (2) the exchange pattern at the sediment-water interface, and (3) integrative measures such as total exchange flux and total storage. Understanding geomorphological controls on groundwater/surface water interactions is attractive because topography is generally better constrained than subsurface parameters, and can be used in data-poor situations. The numerical model represents a hypothetical alluvial plain limited by impervious bedrock on all four sides, and in which the channel meanders according to the sine-generated curve of Langbein and Leopold (1966). As the model (HydroGeoSphere) couples surface and subsurface flow, the stream stage transience is imposed by a fluctuating head at the channel inlet. Preliminary results show that a simple rectangular flood pulse in an idealised sinuous stream without additional complexity can generate multiple flow direction reversals at a single point in the channel. The initial conditions of the groundwater table, the channel sinuosity and the time characteristics of the flood pulse all control exchange flow features in different ways. Results are also compared with 'bank storage' analytical solutions that

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.

  5. Geoethics: what can we learn from existing bio-, ecological, and engineering ethics codes? (United States)

    Kieffer, Susan W.; Palka, John


    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.

  6. La imagen de Felipe II en el Imperio Germano-Romano y en la historiografía alemana y austríaca

    Full Text Available Este articulo retrata la imagen de Felipe II en la historiografía de lengua alemana. Como España ejerció una posición hegemónica en Europa Central, y con relación al Reich ('Camino Español', la imagen del Rey Prudente no pudo ser sino negativa. Llama la atención que el rey atrajera el interés de historiadores tan importantes como Friedrich von Schiller y Leopold von Ranke. Los dos —como el público en general— se interesaron sobre todo por la figura de don Carlos y el presunto papel de Felipe II en la muerte del príncipe. Ranke y su escuela se sintieron fascinados por la construcción y los problemas del Imperio español. Pero en general durante el siglo xx la historiografía en los países de lengua alemana no mostró gran interés por el Rey Prudente, ya que hasta la fecha carecemos de una biografía escrita por un historiador de lengua alemana.This article outlines the image of Philip II in the German-speaking historiography. As Spain exercised a hegemonical position with regard to the 'Reich', and especially at its western territories ('Spanish Road', the image of Philip was mainly a negative one. It is interesting to note that this king attracted the attention of some the most prominent historians in Germán language: Friedrich von Schiller and especially Leopold von Ranke; both — as the Germán public— were interested (although not exclusively in the death of Don Carlos and the possible role Philip played in it. Ranke and this followers were also fascinated by the size and problems of Spanish Empire. But generally speaking one could say that the «prudent king» stood not in the forefront of interest of German-speaking historians, as did Gustav Adolf, Richelieu or Louis XVI.

    Full Text Available Mehmet Âkif’s view to Russians is negative because of Panslavist-emperialist policies that carried out by Russian Tsars and the long-term Ottoman Russian Wars in 19th century. The Central Asia, Caucasia and Balkan nations of problems and sorrows that suffered from Russians, have been expressed usually in the falling period of Ottoman State’s in Âkif’s poems. But expressing these, Âkif did not become an enemy of Russian peoples. He only opposed to Russian State’s policy in that time. Âkif who adopts (appropriates “justice” as the most important principle during his life, has expressed his admiration to Russian literature and art in any case. Âkif loved and respected Russian painters Feldman, Jewish origin Russian pianist Leopold Godowsky and Mari Mençenko that looked after himself at the last days of his life. 19. yüzyılda Rus Çarlarının yürüttüğü Panslavist-emperyalist politikalardan ve uzun süren Osmanlı-Rus Savaşlarından dolayı Mehmet Âkif’in Ruslara bakışı olumsuzdur. Âkif’in şiirlerinde genellikle Osmanlı Devleti’nin yıkılış döneminde sahipsiz kalan Orta Asya, Kafkasya ve Balkan milletlerinin Ruslardan çektiği sıkıntılar ve acılar dile getirilir. Fakat Âkif, bunları dile getirirken Rus halkına düşmanlık beslememiş, sadece Rus devletinin o zaman yürüttüğü politikalara karşı çıkmıştır. Hayatı boyunca hakkaniyeti kendisine en önemli şiar edinen Âkif, her fırsatta Rus edebiyatına ve sanatına olan hayranlığını da ifade etmiştir. Rus ressam Feldman ve Yahudi asıllı Rus piyanist Leopold Godowsky ve son günlerinde ona bakan hastabakıcı Mari Mançenko Âkif’in sevdiği ve saygı duyduğu Ruslardır.

  8. The brain–the organ of the psychic (The lesions / the defense mechanisms) (United States)

    Ciurea, AV


    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

  9. Attention regulates the plasticity of multisensory timing. (United States)

    Heron, James; Roach, Neil W; Whitaker, David; Hanson, James V M


    Evidence suggests than human time perception is likely to reflect an ensemble of recent temporal experience. For example, prolonged exposure to consistent temporal patterns can adaptively realign the perception of event order, both within and between sensory modalities (e.g. Fujisaki et al., 2004 Nat. Neurosci., 7, 773-778). In addition, the observation that 'a watched pot never boils' serves to illustrate the fact that dynamic shifts in our attentional state can also produce marked distortions in our temporal estimates. In the current study we provide evidence for a hitherto unknown link between adaptation, temporal perception and our attentional state. We show that our ability to use recent sensory history as a perceptual baseline for ongoing temporal judgments is subject to striking top-down modulation via shifts in the observer's selective attention. Specifically, attending to the temporal structure of asynchronous auditory and visual adapting stimuli generates a substantial increase in the temporal recalibration induced by these stimuli. We propose a conceptual framework accounting for our findings whereby attention modulates the perceived salience of temporal patterns. This heightened salience allows the formation of audiovisual perceptual 'objects', defined solely by their temporal structure. Repeated exposure to these objects induces high-level pattern adaptation effects, akin to those found in visual and auditory domains (e.g. Leopold & Bondar (2005) Fitting the Mind to the World: Adaptation and Aftereffects in High-Level Vision. Oxford University Press, Oxford, 189-211; Schweinberger et al. (2008) Curr. Biol., 18, 684-688).

  14. 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.

  15. Aspects of the history of X-ray therapy in Austria

    International Nuclear Information System (INIS)

    Wyklicky, H.


    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. (author)

    Full Text Available El aumento de la población y la cobertura de los sistemas de salud, así como el crecimiento del mercado farmacéutico, ha dado lugar a la presencia de una nueva generación de residuos peligrosos, que no habían sido considerados como tal. En Colombia, no se han realizado suficientes estudios relacionados con el impacto ambiental ocasionado por la disposición final de medicamentos, porque no existen cifras disponibles acerca de la cantidad depositada diariamente en rellenos sanitarios, destruida en plantas gestoras de residuos peligrosos o encontrada en plantas de tratamiento de aguas residuales. Se encontró en esta investigación que sólo en Bogotá, se destruyen en promedio anualmente 9.310.123 unidades farmacéuticas de productos de control especial, sin considerar las unidades desechadas a nivel doméstico. Para estudiar el impacto ambiental, se seleccionó el principio activo lorazepam, la información sobre la cantidad del medicamento consumida y destruida en plantas gestoras de residuos peligrosos en la ciudad de Bogotá, durante los años 2012 y 2013, fue aportada por el Fondo Nacional de Estupefacientes. Los datos fueron evaluados utilizando la matriz de Leopold, software especializado y ensayos de laboratorio complementarios. Este estudio pretende sensibilizar a fabricantes, prescriptores y pacientes sobre la responsabilidad ambiental en el uso de medicamentos de control especial.

  17. Andrzej Trautman, Ivor Robinson, and the foundations of gravitational radiation theory (United States)

    Salisbury, Donald

    It is especially pertinent following the momentous detection of gravitational waves by LIGO and the death of Ivor Robinson in 2016 that we investigate the central role played by the Polish physicist Andrzej Trautman and his dear collaborator Robinson in helping to establish the foundations of gravitational wave research. Trautman was a student of Leopold Infeld who had famously rejected the reality of gravitational waves. Yet Trautman's intuition, informed in part by his training as a radio engineer, led him to be the first to correctly pose asymptotic boundary conditions that described the mass loss of an isolated system through emitted gravitational radiation. His series of papers announcing these results were published in a then obscure Polish journal. Fortunately, though, Felix Pirani visited Warsaw in 1957 and he was so impressed with Trautman that he arranged for him to visit his group at King's College in London. Trautman's lectures in London won him wide admiration, and significantly affected the subsequent work on gravitational wave solutions of Einstein's equations in the group led by Hermann Bondi. This was also the occasion in which Trautman and Robinson discovered a deep and abiding mathematical affinity, resulting in the discovery of exact solutions of Einstein's equations that could be interpreted as representing gravitational radiation. This talk is based in part on an interview with Trautman conducted in Warsaw in June, 2016.

  18. 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.

  20. 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.

  1. 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.

  3. Hybrid ventilation systems and high performance buildings

    Energy Technology Data Exchange (ETDEWEB)

    Utzinger, D.M. [Wisconsin Univ., Milwaukee, WI (United States). School of Architecture and Urban Planning


    This paper described hybrid ventilation design strategies and their impact on 3 high performance buildings located in southern Wisconsin. The Hybrid ventilation systems combined occupant controlled natural ventilation with mechanical ventilation systems. Natural ventilation was shown to provide adequate ventilation when appropriately designed. Proper control integration of natural ventilation into hybrid systems was shown to reduce energy consumption in high performance buildings. This paper also described the lessons learned from the 3 buildings. The author served as energy consultant on all three projects and had the responsibility of designing and integrating the natural ventilation systems into the HVAC control strategy. A post occupancy evaluation of building energy performance has provided learning material for architecture students. The 3 buildings included the Schlitz Audubon Nature Center completed in 2003; the Urban Ecology Center completed in 2004; and the Aldo Leopold Legacy Center completed in 2007. This paper included the size, measured energy utilization intensity and percentage of energy supplied by renewable solar power and bio-fuels on site for each building. 6 refs., 2 tabs., 6 figs.

  4. Avoiding Environmental Catastrophes: Varieties of Principled Precaution

    Directory of Open Access Journals (Sweden)

    Alan R. Johnson


    Full Text Available The precautionary principle is often proposed as a guide to action in environmental management or risk assessment, and has been incorporated in various legal and regulatory contexts. For many, it reflects the common sense notion of being safe rather than sorry, but it has attracted numerous critics. At times, proponents and critics talk at cross purposes, due to the multiplicity of ways the precautionary principle has been formulated. The approach taken here is to examine four general varieties of precaution, relating each to arguments made in various contexts by others. First, I examine the parallel between the precautionary principle and an argument referred to as Pascal's wager. Critics are right to dismiss versions of the precautionary principle that follow the logic of Pascal's wager, because that argument requires assumption of an infinite catastrophe, which is seldom the case in environmental decisions. Second, I explore precaution viewed as an instance of the phenomenon of ambiguity aversion as described by Daniel Ellsberg. Third, I evaluate precautionary perspectives on our duties to future generations, drawing inspiration from the views of Gifford Pinchot. Fourth, I consider the precautionary principle as an instance of Aldo Leopold's notion of intelligent tinkering. Although controversy persists, I find that a legitimate theoretical foundation exists to implement Ellsbergian, Pinchotian and Leopoldean varieties of precaution in environmental decision making. Additionally, I remark on the role of adaptive management and maintaining resilience in ecological and social systems as an approach to implementing the precautionary principle.

  5. 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.'

  6. Record-breaking early flowering in the eastern United States. (United States)

    Ellwood, Elizabeth R; Temple, Stanley A; Primack, Richard B; Bradley, Nina L; Davis, Charles C


    Flowering times are well-documented indicators of the ecological effects of climate change and are linked to numerous ecosystem processes and trophic interactions. Dozens of studies have shown that flowering times for many spring-flowering plants have become earlier as a result of recent climate change, but it is uncertain if flowering times will continue to advance as temperatures rise. Here, we used long-term flowering records initiated by Henry David Thoreau in 1852 and Aldo Leopold in 1935 to investigate this question. Our analyses demonstrate that record-breaking spring temperatures in 2010 and 2012 in Massachusetts, USA, and 2012 in Wisconsin, USA, resulted in the earliest flowering times in recorded history for dozens of spring-flowering plants of the eastern United States. These dramatic advances in spring flowering were successfully predicted by historical relationships between flowering and spring temperature spanning up to 161 years of ecological change. These results demonstrate that numerous temperate plant species have yet to show obvious signs of physiological constraints on phenological advancement in the face of climate change.

  7. Landscapes of promise: An examination of students' journals written during a cross-cultural wilderness experience (United States)

    Freund, Judith Ann


    This paper is an examination of nature journals written by ten American and ten Russian high school students during a cross-cultural exchange that provided experiences in selected national wilderness areas designated by the respective countries. The students participated in a backpacking excursion in the Lee Metcalf Wilderness Area of Montana in the summer of 1994, and a camping experience in the wilderness areas in the provincial region of Penza, Russia in the summer of 1995. The examination of the journals focuses on the following areas: aesthetic "peak" experiences; spiritual inspiration derived from experiences in nature; attitudes toward the preservation of wildlife; and environmental ethics. The students' attitudes toward the environment is compared using student-identified cultural values of both the Russian and the American students. Also discussed is the viability of the students' reflections as natural history journal-writing, with references to selected natural history authors, including Henry David Thoreau, Aldo Leopold and Anne Dillard. Because the experience focused on wilderness preservation students were invited to speculate about how to develop and reinforce essential attitudes that are respectful of ecology. Conclusions they reached included the necessity to economic security at some level and the notion that direct experience in the environment is essential to developing an attitude that will engender an ethics of caring within their--as well as other--cultural groups.

  8. Lessons from the Trenches (United States)

    Lubchenco, J.


    One of the most important roles of science is to inform the discussions and decisions of individuals and institutions. In a world that is changing rapidly, information is urgently needed to help citizens and leaders understand what's happening, what's causing changes, what the implications are and what are the likely consequences of various options. Most everyone agrees that decisions should be informed (not dictated) by scientific information, but achieving that goal has proven a challenge. Decision-makers need to have access to scientific information that is understandable, relevant, useable, current and credible. However, the science is complex, nuanced and difficult to communicate simply. Most scientists are ill equipped to speak in language that is non-technical. Many academic scientists are wary of talking to the press. Academia does not generally reward time spent doing outreach. As a consequence, others step into the breach and communicate their version of `the science.' All too often this means that vested interests spin, distort or cherry-pick information. The result is that decisions are made without good scientific knowledge and science is seen increasingly as a weapon, not as useful knowledge. The presentation will focus on how one program, the Aldo Leopold Leadership Program is training academic environmental scientists to be better communicators of their science to non-scientists. Lessons learned and suggestions for revolutionizing the communication of scientific information will be offered.

  9. Expressions of ecological identity across the life span of eight environmental exemplars (United States)

    Seydel, Jennifer

    While there is a substantial body of literature looking at various aspects of ecological identity and factors that influence it, there has been less work done on how an individual's ecological identity changes with time. Much of that work is limited to short segments of the life span (e.g. the impact of wilderness experiences). This dissertation attempts to address this perceived gap by investigating how the ecological identity of eight environmental exemplars changed during the course of his or her life. What has emerged from this qualitative grounded theory investigation of the lives and works of Charles Darwin, John Muir, Aldo Leopold, Marjory Stoneman Douglas, Hazel Wolf, Rachel Carson, James Lovelock and E.O. Wilson are five sequential expressions of ecological identity. These 'stages' serve as a framework to explain ecological identity as a developmental process, both fluid and continuous, rather than at) end product. The development of an ecological identity is traced, through the development of five cognitive foundations and their alignment with five emotional foundations that reflect a progression from a sensory interaction and a kinship bond with nature into a deep understanding of the interconnectedness of all aspects of the planet. The findings reveal the evolution of an ecological identity and suggest the importance of looking beyond content knowledge in the nurturing of ecological attitudes, values, and lifestyles.

  10. Record-breaking early flowering in the eastern United States.

    Elizabeth R Ellwood

    Full Text Available Flowering times are well-documented indicators of the ecological effects of climate change and are linked to numerous ecosystem processes and trophic interactions. Dozens of studies have shown that flowering times for many spring-flowering plants have become earlier as a result of recent climate change, but it is uncertain if flowering times will continue to advance as temperatures rise. Here, we used long-term flowering records initiated by Henry David Thoreau in 1852 and Aldo Leopold in 1935 to investigate this question. Our analyses demonstrate that record-breaking spring temperatures in 2010 and 2012 in Massachusetts, USA, and 2012 in Wisconsin, USA, resulted in the earliest flowering times in recorded history for dozens of spring-flowering plants of the eastern United States. These dramatic advances in spring flowering were successfully predicted by historical relationships between flowering and spring temperature spanning up to 161 years of ecological change. These results demonstrate that numerous temperate plant species have yet to show obvious signs of physiological constraints on phenological advancement in the face of climate change.

  11. Phenology Across the LTER Network: Initial Findings, Future Directions (United States)

    Henebry, G. M.


    Phenology is, in the words of Aldo Leopold, a "horizontal science" that cuts across and binds together multiple biological disciplines. It is a far-reaching but poorly understood aspect of the environmental sciences. Phenological research has been a component of the Long Term Ecological Research (LTER) Network at several sites over the years. However, it has not received the attention or resources to bring it to the forefront as an effective theme for interdisciplinary and cross-site synthesis. With the recent establishment of the USA National Phenology Network (USA-NPN), it is appropriate to assess the status of phenological knowledge across the LTER Network. A workshop funded by the LTER Network Office took place at the Sevilleta Field Station during February 26 to March 2, 2007. From the workshop three main products emerged: (1) an inventory of LTER phenology datasets, (2) establishment of a website to facilitate information interchange, and (3) a white paper recommending next steps for the LTER Network to engage the USA-NPN. This poster relates the findings and recommendations of the workshop, including a summary of phenologically explicit and phenologically implicit LTER datasets and illustrations of how the climatic envelopes described by simple weather variables can provide context for phenological comparisons within and across sites.

  12. Joseph A. Burton Forum Award Talk: Remembering our Humanity: the deep impact of the Russell-Einstein Manifesto (United States)

    Lewis, Patricia M.


    ``There lies before us, if we choose, continual progress in happiness, knowledge, and wisdom. Shall we, instead, choose death, because we cannot forget our quarrels? We appeal as human beings to human beings: Remember your humanity, and forget the rest.'' Days before his death, Albert Einstein joined Bertrand Russell and other notable scientists and philosophers in issuing a statement calling for the abolition of war and for governments to ``find peaceful means for the settlement of all matters of dispute between them." As a first step, they called for the renunciation of nuclear weapons. The initiative led to the establishment of the Pugwash Conferences on Science and World Affairs, which bring together influential scholars and public figures concerned with reducing the danger of armed conflict and seeking cooperative solutions for global problems. The Russell-Einstein Manifesto has had a major impact on the way in which people discuss the issues of peace and war. The paper traces the growing awareness of the meaning of war, ways in which violent conflict can be prevented, particularly in the nuclear age, and the humanitarian imperative for so doing. From the Russell-Einstein Manifesto, London, 9 July 1955, signed also by Max Born, Percy W. Bridgman, Leopold Infeld, Frederic Joliot-Curie, Herman J. Muller, Linus Pauling, Cecil F.

  13. 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.

  14. 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.

  15. Similarity of Cross-Sectional Characteristics of Costal Plain Streams of the Southeastern United States (United States)

    Vesely, W. S.; Parola, A. C.


    The Coastal Plain physiographic region of the southeastern United States encompasses over 1.2 million km2. Analysis of data from six separate geomorphic studies conducted in five of the 19 states having a Coastal Plain region suggests that streams of the Coastal Plain region have very similar correlations betweein bankfull cross section area (R2 = 0.92, n = 123) and discharge (R2 = 0.85, n = 77) with drainage basin area, despite geographic and hydrologic differences. Analysis of these data also shows that bankfull cross section area for southeastern Coastal Plain streams is 47% less than that indicated for other eastern US rivers by Dunne and Leopold (1978). Furthermore, estimates of bankfull discharge have an average return period of 1.14 years on the annual series. These bankfull flows range from 6.2-90% of the 1.5-year flow, often considered to represent the bankfull flow condition, and 4.4-75% of the 2-year flow, which some have suggested for restoration design. The strong correlation of these data supports the concept of using regional morphologic data for initiating assessments and should be considered as an important component of restoration design for streams of the southeastern Coastal Plain.

  16. 1987 Robert E. Horton Award to Thomas Dunne (United States)

    Dunne, Thomas

    Robert Horton demonstrated in his seminal 1945 paper that physically based quantitative models for landscape evolution can be constructed by using predicted overland flow in a sediment transport equation for sheetwash. He envisioned drainage network evolution by infiltration-limited overland flow as a process of channel incision, network growth, and then abstraction to a stable channel network fed by hillslopes too short for channel initiation. Not until the work of Tom Dunne in the late 1960s in the Sleepers River watershed, Vermont, was it realized that overland flow, and consequently hillslope evolution, could occur by an entirely different mechanism than that proposed by Horton. Dunne showed that in certain predictable zones of the landscape, exfiltration from saturated grounds adds to precipitation on the soil surface to form what he later called saturation overland flow. Many researchers have since found that this form of overland flow occurs in humid and semiarid landscapes throughout the world. So clear is Dunne's contribution to defining this process that some refer to it as the “Dunne mechanism” to distinguish it from “Horton overland flow.” His work also documented unquestionably the applicability of the partial area concept in explaining runoff generation. Because of this work, his research in snowmelt runoff, and his subsequent authorship with Luna Leopold of the widely used book entitled Water in Environmental Planning, Dunne has established himself as a leader of process hydrology.

  18. Rabbi Wolf Meisel’s Attempt to Establish a Midstream Judaism in Hungary, 1859-1867

    Directory of Open Access Journals (Sweden)

    Wilke Carsten


    Full Text Available During the years that led to the Hungarian Jewish schism of 1869, Orthodoxy reigned relatively unchallenged in communities of long standing or East European immigration, while Neology spread in the recently founded urban synagogues. Only the steadily growing community of Pest, Hungary’s economic capital, presented an appropriate testing-ground for religious forces that tried to withstand the progressive cleavage. My paper will focus on the exceptional moment after 1859, when Chief Rabbi Wolf Meisel (1815-1867, a Bohemian compatriot of Zacharias Frankel, formulated in his short-lived journal Der Carmel a popular midstream ideology that was largely independent from the Breslau-style „Science of Judaism.” Jointly attacked by the Orthodox party as well as by Leopold Löw’s progressive journal Ben-Chananja, Meisel’s religious position was undermined by the rise of Hungarian nationalism and the more successfully mediatized Magyarization efforts of the Neologs. My paper will ask for the ideological and social characteristics of Rabbi Meisel’s failed peace movement, the controversy it aroused, and its long-term repercussions on Hungarian Jewish modernism.

  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. 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.

  2. Tourism Pedagogy and Visitor Responsibilities in Destinations of Local-Global Significance: Climate Change and Social-Political Action

    Directory of Open Access Journals (Sweden)

    Tazim Jamal


    Full Text Available This paper examines the issue of climate change pedagogy and social action in tourism, with particular interest in globally-significant destinations under threat from climate change. Little is understood of the role and responsibility of visitors as key stakeholders in climate change-related action or the potential of such sites to foster environmental learning, as well as social and political action on climate change. Drawing on insights from Aldo Leopold and John Dewey, it is argued here that destinations that are valued intrinsically for their ecological and cultural importance are (or ought to be sites of enjoyment and pedagogy, facilitating experiential learning, care, responsibility and civic action towards their conservation. An exploratory case study of visitors to the Great Barrier Reef offers corroborative insights for such a “reef ethic” as described in this paper, related to visitor experience, learning and action in this World Heritage Area. The results of this paper support the need for a stronger pedagogic role to be adopted by tourism experience providers and site managers to facilitate climate change literacy and responsible action (hence facilitating global environmental citizenship. Their responsibility and that of reef visitors is discussed further.

  3. 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.

    Full Text Available Our own body, both as a physical object (Körper and as a focus experiencing sensations (Leib is usually the axis of our self-identification. In this the mode of presentation of one's own body, in correlation of its accessibility "from the outside" and "from the inside", in which I receive my own body as one and the same, however, one cannot find an answer to the question about how can the bodily (corporal identification be constituted, which does not have a uniaxial character as it is, e.g. in case of the painterly perception of trompe-l'oeil or during the film showing. 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.

  6. 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.

  11. [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.

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.

  13. Experimental Investigation of the Wake-Mediated Interaction Forces Between Dust Particles in a Flowing Plasma (United States)

    Petrov, Oleg; Lisin, Evgeny; Statsenko, Konstantin; Hyde, Truell; Carmona, Jorge


    An anisotropic spatial dependence of the wake-mediated interaction forces between dust particles in a plasma flow was studied experimentally. The measurements were performed at CASPER for the vertically aligned chain self-organized from 11 microparticles inside a glass box placed on the lower electrode of a RF gas discharge chamber. The experiment was conducted in argon plasma at 137 mTorr and monodisperse MF particles having diameters of 8.93 microns were used. To recover the wake-mediated interaction forces we improved the method based on solving the inverse Langevin problem of the dynamics of many interacting particles. To determine 3D trajectories of the particles we used a stereoscopic video surveillance system. Spatial profiles of the forces with which upstream particles act on downstream ones and vice versa were obtained. The difference between the interparticle interaction forces in the opposite directions indicates its non-reciprocal nature and can be associated with the wake. The peak position of the wake-field and the space charge concentrated in it were evaluated by the force profile analysis. The data analysis and interaction force recovering in this work was supported by the Russian Science Foundation (O.F. Petrov, K.B. Stacenko, E.?.Lisin) through Grant No. 14-12-01440).

  14. Measuring Solar Coronal Magnetism during the Total Solar Eclipse of 2017 (United States)

    Gibson, K. L.; Tomczyk, S.


    The total solar eclipse on August 21, 2017 provided a notable opportunity to measure the solar corona at specific emission wavelengths to gain information about coronal magnetic fields. Solar magnetic fields are intimately related to the generation of space weather and its effects on the earth, and the infrared imaging and polarization information collected on coronal emission lines here will enhance the scientific value of several other ongoing experiments, as well as benefit the astrophysics and upper atmosphere communities. Coronal measurements were collected during the 2 minute and 24 second totality period from Casper Mountain, WY. Computer-controlled telescopes automatically inserted four different narrow band pass filters to capture images in the visible range on a 4D PolCam, and in the infrared range on the FLIR 8501c camera. Each band pass filter selects a specific wavelength range that corresponds to a known coronal emission line possessing magnetic sensitivity. The 4D PolCam incorporated a novel grid of linear polarizers precisely aligned with the micron scale pixels. This allowed for direct measurement of the degree of linear polarization in a very small instrument with no external moving parts as is typically required. The FLIR offers short exposure times to freeze motion and output accurate thermal measurements. This allowed a new observation of the sun's corona using thermo infrared technology.

  15. 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

  16. 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.

  18. Coordinating Shared Activities (United States)

    Clement, Bradley


    Shared Activity Coordination (ShAC) is a computer program for planning and scheduling the activities of an autonomous team of interacting spacecraft and exploratory robots. ShAC could also be adapted to such terrestrial uses as helping multiple factory managers work toward competing goals while sharing such common resources as floor space, raw materials, and transports. ShAC iteratively invokes the Continuous Activity Scheduling Planning Execution and Replanning (CASPER) program to replan and propagate changes to other planning programs in an effort to resolve conflicts. A domain-expert specifies which activities and parameters thereof are shared and reports the expected conditions and effects of these activities on the environment. By specifying these conditions and effects differently for each planning program, the domain-expert subprogram defines roles that each spacecraft plays in a coordinated activity. The domain-expert subprogram also specifies which planning program has scheduling control over each shared activity. ShAC enables sharing of information, consensus over the scheduling of collaborative activities, and distributed conflict resolution. As the other planning programs incorporate new goals and alter their schedules in the changing environment, ShAC continually coordinates to respond to unexpected events.

    ITT Industries Space Systems Division (Space Systems) has developed an airborne natural gas leak detection system designed to detect, image, quantify, and precisely locate leaks from natural gas transmission pipelines. This system is called the Airborne Natural Gas Emission Lidar (ANGEL) system. The ANGEL system uses a highly sensitive differential absorption Lidar technology to remotely detect pipeline leaks. The ANGEL System is operated from a fixed wing aircraft and includes automatic scanning, pointing system, and pilot guidance systems. During a pipeline inspection, the ANGEL system aircraft flies at an elevation of 1000 feet above the ground at speeds of between 100 and 150 mph. Under this contract with DOE/NETL, Space Systems was funded to integrate the ANGEL sensor into a test aircraft and conduct a series of flight tests over a variety of test targets including simulated natural gas pipeline leaks. Following early tests in upstate New York in the summer of 2004, the ANGEL system was deployed to Casper, Wyoming to participate in a set of DOE-sponsored field tests at the Rocky Mountain Oilfield Testing Center (RMOTC). At RMOTC the Space Systems team completed integration of the system and flew an operational system for the first time. The ANGEL system flew 2 missions/day for the duration for the 5-day test. Over the course of the week the ANGEL System detected leaks ranging from 100 to 5,000 scfh.

  20. Pathogenesis of the discal cysts communicating with an adjacent herniated disc. Histological and ultrastructual studies of two cases. (United States)

    Kobayashi, Shigeru; Takeno, Kenichi; Uchida, Kenzo; Yayama, Takafumi; Nakajima, Hideaki; Miyazaki, Tsuyoshi; Guerrero, Alexander; Baba, Hisatoshi


    Discal cyst of the lumbar spine is a very rare cause of back pain and sciatica. We report two cases of discal cysts communicating with an adjacent herniated disc. From CT and MRI findings, they were diagnosed as having a discal cyst in the epidural space, which compressed the nerve root. After an adequate surgical field was obtained with a microscope and a Casper retractor, the discal cyst could be excised and satisfactory decompression of the adjacent nerve root was obtained. From histological and electron microscopic study, the presence of residual herniated tissues was confirmed in the cyst wall. Macrophages played an important role in the absorption of herniated tissue and the formation of the discal cyst. Hemorrhage in the cyst wall will make the serous hemorrhagic fluid-filled cystic structure in the absorbed spaces of the prolapsed disc. In this study, we confirmed that the discal cyst could have developed from the absorption process of a disc herniation. Copyright 2009 Société française de rhumatologie. Published by Elsevier SAS.

  1. The embryo as moral work object: PGD/IVF staff views and experiences. (United States)

    Ehrich, Kathryn; Williams, Clare; Farsides, Bobbie


    We report on one aspect of a study that explored the views and experiences of practitioners and scientists on social, ethical and clinical dilemmas encountered when working in the field of preimplantation genetic diagnosis (PGD) for serious genetic disorders. The study produced an ethnography based on observation, interviews and ethics discussion groups with staff from two PGD/IVF Units in the UK. We focus here on staff perceptions of work with embryos that entails disposing of 'affected' or 'spare' embryos or using them for research. A variety of views were expressed on the 'embryo question' in contrast to polarised media debates. We argue that the prevailing policy acceptance of destroying affected embryos, and allowing research on embryos up to 14 days leaves some staff with rarely reported, ambivalent feelings. Staff views are under-researched in this area and we focus on how they may reconcile their personal moral views with the ethical framework in their field. Staff construct embryos in a variety of ways as 'moral work objects'. This allows them to shift attention between micro-level and overarching institutional work goals, building on Casper's concept of 'work objects' and focusing on negotiation of the social order in a morally contested field.

  2. The Inhibitory Effect of 3β-Hydroxy-12-oleanen-27-oic Acid on Growth and Motility of Human Hepatoma HepG2 Cells through JNK and Akt Signaling Pathway

    Juanjuan Wang


    Full Text Available 3β-Hydroxy-12-oleanen-27-oic acid (ATA was a main antitumor active triterpene from the rhizomes of Astilbe chinensis. In this study, we investigated its effects on growth, apoptosis, cell cycle, motility/invasion, and metatasis in human hepatoma HepG2 cells in vitro and antimetastasis of B16-F10 melanoma in mice in vivo, as well as its molecular mechanisms of action using a high-throughput Cancer Pathway Finder PCR Array. ATA could not only induce tumor cells into apoptosis through the activation of both extrinsic and intrinsic pathways, arrest HepG2 cells in G2/M phase, but also suppress the invasion and metastasis abilities of HepG2 cells and the lung metastasis of B16-F10 melanoma in mice. PCR array assay revealed that ATA upregulated 9 genes including CDKN1A, MDM2, CFLAR (CASPER, TNFRSF10B (DR5, c-Jun, IL-8, THBS1, SERPINB5 (maspin, and TNF and downregulated 8 genes such as CCNE1, AKT, ANGPT1, TEK, TGFBR1, MMP9, U-PA, and S100A4. These results indicate that ATA could exert antitumor effects through activating JNK/MAPK and suppressing AKT signal transduction pathways and that ATA might be a potent anticancer agent.

    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.

  4. The search for axion-like dark matter using magnetic resonance (United States)

    Sushkov, Alexander; Casper Collaboration


    The nature of dark matter is one of the most important open problems in modern physics, and it is necessary to develop techniques to search for a wide class of dark-matter candidates. Axions, originally introduced to resolve the strong CP problem in quantum chromodynamics (QCD), and axion-like particles (ALPs) are strongly motivated dark matter candidates. Nuclear spins interacting with axion-like background dark matter experience an energy shift, oscillating at the frequency equal to the axion Compton frequency. The Cosmic Axion Spin Precession Experiments (CASPEr) use precision magnetometry and nuclear magnetic resonance techniques to search for the effects of this interaction. The experimental signature is precession of the nuclear spins under the condition of magnetic resonance: when the bias magnetic field is tuned such that the nuclear spin sublevel splitting is equal to the axion Compton frequency. These experiments have the potential to detect axion-like dark matter in a wide mass range (10-12 eV to 10-6 eV, scanned by changing the bias magnetic field from approximately 1 gauss to 20 tesla) and with coupling strengths many orders of magnitude beyond the current astrophysical and laboratory limits, and all the way down to those corresponding to the QCD axion.

  5. Maps showing thermal maturity of Upper Cretaceous marine shales in the Wind River Basin, Wyoming (United States)

    Finn, Thomas M.; Pawlewicz, Mark J.


    The Wind River Basin is a large Laramide (Late Cretaceous through Eocene) structural and sedimentary basin that encompasses about 7,400 square miles in central Wyoming. The basin is bounded by the Washakie Range, Owl Creek, and southern Bighorn Mountains on the north, the Casper arch on the east and northeast, the Granite Mountains on the south, and the Wind River Range on the west. Important conventional and unconventional oil and gas resources have been discovered and produced from reservoirs ranging in age from Mississippian through Tertiary. It has been suggested that various Upper Cretaceous marine shales are the principal hydrocarbon source rocks for many of these accumulations. Numerous source rock studies of various Upper Cretaceous marine shales throughout the Rocky Mountain region have led to the conclusion that these rocks have generated, or are capable of generating, oil and (or) gas. With recent advances and success in horizontal drilling and multistage fracture stimulation there has been an increase in exploration and completion of wells in these marine shales in other Rocky Mountain Laramide basins that were traditionally thought of only as hydrocarbon source rocks. Important parameters that control hydrocarbon production from shales include: reservoir thickness, amount and type of organic matter, and thermal maturity. The purpose of this report is to present maps and a structural cross section showing levels of thermal maturity, based on vitrinite reflectance (Ro), for Upper Cretaceous marine shales in the Wind River Basin.

  6. Draft environmental statement related to the operation of Sand Rock Mill Project (Docket No. 40-8743)

    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

  8. Characterization of electron clouds in the Cornell Electron Storage Ring Test Accelerator using TE-wave transmission

    Directory of Open Access Journals (Sweden)

    S. De Santis


    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.

    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.

    Veloski, G.A.; Hammack, R.W.; Stamp, V. (Rocky Mountain Oilfield Testing Center); Hall, R. (Rocky Mountain Oilfield Testing Center); Colina, K. (Rocky Mountain Oilfield Testing Center)


    A helicopter magnetic survey was conducted in August 2007 over 15.6 sq mi at the Naval Petroleum Reserve No. 3’s (NPR-3) Teapot Dome Field near Casper, Wyoming. The survey’s purpose was to accurately locate wells 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 for EOR, which requires a complete well inventory with accurate locations for all existing wells. The magnetic survey was intended to locate wells missing from the well database and to provide accurate locations for all wells. The ability of the helicopter magnetic survey to accurately locate wells was accomplished by comparing airborne well picks with well locations from an intense ground search of a small test area.

  14. 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

  15. Analysing the meandering rivers responses to the slope-changes, depending on their bankfull discharge - Case study in the Pannonian Basin (United States)

    Petrovszki, Judit; Timár, Gábor; Molnár, Gábor


    The multi-variable connection between the channel slope, bankfull discharge and sinuosity values were analysed to get a mathematical formula, which describes the responses of the rivers, and gives the probable sinuosity values for every slope and discharge values. Timár (2003) merged two planar diagrams into a quasi 3D graph. One of them displayed how the river pattern changes, according to the slope and bankfull discharge values (Leopold and Wolmann, 1957; Ackers and Charlton, 1971); the other based on flume experiments, and gives a connection between the slope and sinuosity (Schumm and Khan, 1972). The result graph suggests that the slope-sinuosity connection also works along the natural rivers, for every discharge values. The aim of this work was to prove this relation, and describe it numerically. The sinuosity values were calculated along the natural, meandering river beds, using historical maps (2nd Military Survey of the Habsburg Empire, from the 19th century). The available slope and discharge values were imported from a database measured after the main river control works, at the beginning of the 20th century (Viczián, 1905). Analysing the reports of the river control works, the natural slope could be computed for every river sections. The mean discharges were also converted to bankfull discharges. Neither long time series, nor cross sectional areas were obtainable, so other method was used to generate the bankfull discharge. After the above mentioned corrections a quadratic polynomial surface was fitted onto these points with least squares regression. The cross section of this surface follows the theoretical slope-sinuosity graph, verifying that the flume experiments and natural rivers behave similarly. The differences between the fitted surface and the original points were caused by other river parameters, which also affect the natural rivers (e.g. the sediment discharge). Furthermore, this graph confirms the connection between the slope and sinuosity

  16. Auerbach e lo Storicismo tedesco

    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. Regional curve development and selection of a reference reach in the non-urban, lowland sections of the Piedmont physiographic province, Pennsylvania and Maryland (United States)

    White, Kirk E.


    Stream-restoration projects utilizing naturalstream designs frequently are based on the bankfull- channel characteristics of a stream reach that is accommodating streamflow and sediment transport without excessive erosion or deposition. The bankfull channel is identified by the use of field indicators and confirmed with tools such as regional curves. Channel dimensions were surveyed at six streamflow-measurement stations operated by the U.S. Geological Survey in the Gettysburg-Newark Lowlands Section and Piedmont Lowlands Section of the Piedmont Physiographic Province in Pennsylvania and Maryland. Regional curves were developed from regression analyses of the relation between drainage area and cross-sectional area, mean depth, width, and streamflow of the bankfull channel. Regional curves were used to confirm the identification of the bankfull channel at a reference reach. Stream dimensions and characteristics of the reference reach were measured for extrapolation into the design of a steam-restoration project on Bermudian Creek in Adams County, Pa.Dimensions for cross-sectional area, mean depth, width, and computed streamflow of the bankfull channel in all surveyed riffle cross sections in the reference reach were within the 95-percent confidence interval bounding the regression line representing bankfull channel geometry in the Lowland Sections of the Piedmont Physiographic Province. The average bankfull cross-sectional area, bankfull mean depth, and computed bankfull discharge for riffle cross sections in the reference reach ranged from 15.4 to 16.5 percent less than estimates determined from the lowland regional curves. Average bankfull channel width was about 2 percent greater than estimates. Cross-sectional area, mean depth, and computed streamflow corresponding to the bankfull stage at the reference reach were 31.4, 44.4, and 9.6 percent less, respectively, than estimates derived from the regional curves developed by Dunne and Leopold in 1978.

  18. Achievements of Polish doctors in gastrodiaphanoscopy at the turn of the 19(th) and 20(th) centuries. (United States)

    Kierzek, Andrzej; Paprocka-Borowicz, Małgorzata; Pozowski, Andrzej; Kuciel-Lewandowska, Jadwiga


    Diaphanoscopy/transillumination, the method of shining a bright light through tissues, was devised in the mid-19(th) century and developed after the invention of the light bulb by T.A. Edison. Benjamin Milliot was the first to examine the stomach by means of an incandescent platinum wire. The experiments conducted by Max Einhorn using a device consisting of a Nelaton catheter with an inserted light bulb, were valuable. In Poland the method of gastrodiaphanoscopy was popularized by Teodor Heryng, Mikołaj Rejchman and by Warsaw doctors. They used a diaphanoscope consisting of a gutta-percha probe distally equipped with a metal attachment with a light bulb hidden in it and with a so-called cooling device. The examination would usually be conducted in the standing position after the stomach had been filled with water. Light patches corresponding to the stomach's lower and side boundaries would be obtained. Rejchman's observation, that such a contractile and flexible organ as the stomach, changing its volume and position, is bound to change its light image, was correct. Heryng's and Rejchman's research inspired the foreign researchers Renvier, Leopold Kuttner and John Jacobson. Extensive research was subsequently conducted by C.A. Meltzing and Wilhelm Schwartz. Diaphanoscopy would also be performed by Walery Jaworski, the pioneer of gastrology. He was particularly interested in transillumination of the stomach, peritoneum and omentum tumours. Eugeniusz Kozierowski, a practicing physician from Gorlice, diagnosed neoplastic pylorostenosisusing this method. Gastrodiaphanoscopy is a historical method, now of no value against gastroendoscopy and the state-of-the-art methods of image diagnostics.

  19. 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

  20. 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.

  1. 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

  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.

  3. 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.

  4. The continuous high-precision measurement of the density of flowing blood. (United States)

    Kenner, T; Leopold, H; Hinghofer-Szalkay, H


    The "mechanical oscillator" technique for the measurement of the density of fluids is based on the influence of mass on the natural frequency of a mechanical oscillator. The practical application of this principle was worked out by Kratky et al. (1969) and Leopold (1970). It is demonstrated in this study that the method permits the continuous high-precision measurement of the density of flowing blood in anesthetized animals. The accuracy is 10(5) g/ml, the maximum sampling rate 20/min. As found in rabbits and cats during the control state, physiological blood density changes related to spontaneous blood pressure variations are up to 2-10(4) g/ml. The method can be combined with i.v. injections of isotonic and iso-oncotic solutions to determine cardiac output and blood volume on the basis of a "density dilution" principle. Since the density of the interstitial fluid is lower than that of blood, fluid shifts through the capillary walls can be detected. The effects of hypertonic glucose and of hyperoncotic dextran have been examined. Changes in the density of the arterial blood appear within 10 s after i.v. injection of these fluids. Similarly, density changes result from hemorrhage and reinfusion. During and after i.v. administration of vasoactive drugs (noradrenaline, angiotensin II, acetylcholine), marked transient changes in blood density are seen which obviously reflect the effects of fluid shifts through the capillary walls. During hemorrhagic hypotension we found periodic variations in the blood density synchronous with spontaneously occurring Mayer waves. The new method seems to be a promising tool for investigations physiological and pathological capillary fluid dynamics.

  5. 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.

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. Franz L. Neumann died in 1954 in a car accident.

  7. Who is my audience, what is my message, and know my reporters deadline: How to be more effective communicating with the media (United States)

    Reddy, C. M.


    In the United States where most scientists receive their research support from federal funds, scientists need to expand their audience beyond their peers and consider the taxpayers, too. The media can play an important conduit for scientists and the lay public. However, many scientists do not do the best public relations jobs for their profession. We talk very well with each other and not very well with almost anyone else. We need to learn to avoid jargon, communicate our results more clearly, and examine the relationship between communication techniques and how to assess the outcomes. Scientists assess outcome based only on factual accuracy. Journalists assess their results based on accuracy and storycraft. In my experiences interacting with the media during various oil spills as well as training from the Aldo Leopold Leadership Program, I will discuss how scientists can be more effective when communicating with the media. First, scientists need to understand who their audience is and what their educational background is. In addition, it is important to stay on message and have only one message per interaction with a member of the media. That is, do not confuse a reporter with the results from one study when he or she is really interested in another story or just looking for background information. Last, scientists must understand that the media must often publish their stories with deadlines having timescales of hours and not months or years, hence it is important to be brief and to promptly return phone calls and emails. Hopefully, such efforts between scientists and the media will lead to a more scientifically informed public.

  9. Evaluating landscape health: Integrating societal goals and biophysical process (United States)

    Rapport, D.J.; Gaudet, C.; Karr, J.R.; Baron, Jill S.; Bohlen, C.; Jackson, W.; Jones, B.; Naiman, R.J.; Norton, B.; Pollock, M. M.


    Evaluating landscape change requires the integration of the social and natural sciences. The social sciences contribute to articulating societal values that govern landscape change, while the natural sciences contribute to understanding the biophysical processes that are influenced by human activity and result in ecological change. Building upon Aldo Leopold's criteria for landscape health, the roles of societal values and biophysical processes in shaping the landscape are explored. A framework is developed for indicators of landscape health and integrity. Indicators of integrity are useful in measuring biological condition relative to the condition in landscapes largely unaffected by human activity, while indicators of health are useful in evaluating changes in highly modified landscapes. Integrating societal goals and biophysical processes requires identification of ecological services to be sustained within a given landscape. It also requires the proper choice of temporal and spatial scales. Societal values are based upon inter-generational concerns at regional scales (e.g. soil and ground water quality). Assessing the health and integrity of the environment at the landscape scale over a period of decades best integrates societal values with underlying biophysical processes. These principles are illustrated in two contrasting case studies: (1) the South Platte River study demonstrates the role of complex biophysical processes acting at a distance; and (2) the Kissimmee River study illustrates the critical importance of social, cultural and economic concerns in the design of remedial action plans. In both studies, however, interactions between the social and the biophysical governed the landscape outcomes. The legacy of evolution and the legacy of culture requires integration for the purpose of effectively coping with environmental change.

  10. 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.

  11. Valoración de impactos ecológicos por minería de oro en río Guabas, Valle del Cauca, Colombia

    Diego Esteban Gamboa García


    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.

  12. 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.

  13. 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°.

    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.

  15. Making Science Whole Again: The Role of Academia (United States)

    Lubchenco, J.


    Science in the 21st Century has become increasingly fragmented, not in the usual sense of disciplinary divisions, but with increased specialization in the discovery, teaching, public communication and application aspects of new knowledge. As in the infamous `telephone game', messages passed along through multiple parties, risk distortion. More insidiously, without active and effective checks and balances along the way, information can be and is being deliberately distorted, completely altered, or used selectively. Science, of course, is not the only basis for decision-making; values, politics, economics and other factors should also be considered. Nonetheless, a key role of science is to inform decision-making (not to drive it exclusively). The importance of citizens and leaders having access to accurate scientific information and knowledge is so essential to human well-being that new mechanisms must be found to ensure the integrity of scientific information. Among the multiple changes that are needed to achieve this goal, many of which will be explored in this session, one pertains specifically to the academic scientific community. That change entails growing and supporting stellar scientists who participate directly in discovery AND public communication of knowledge. More scientists whose primary jobs are research and teaching could and should also be actively involved in sharing new knowledge with non-scientists. The public expects this to happen but academia gives it lip service at best. Having more scientists who can communicate scientific knowledge that is understandable, relevant, useable, current and credible to non-technical audiences is a key (though far from the only) factor in protecting the integrity of science. The Aldo Leopold Leadership Program now based at Stanford University's Woods Institute for the Environment is a program that trains tenured, academic environmental scientists to communicate effectively with politicians, business people, the

  16. [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.

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

    Directory of Open Access Journals (Sweden)

    Luis Jair Gómez Giraldo


    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.

  18. 'A profitable company'. Het pantheon als historisch genre in het negentiende-eeuwse België

    Full Text Available 'A profitable company'. The national pantheon as a historical genre in nineteenth-century BelgiumAfter the Revolution of 1830, the new Belgian nation state was in a patriotic mood. It celebrated its national glory in pantheons, imaginary temples in which the heroes from the national past were represented and accumulated. These pantheons were almost omnipresent in the public spaces of the kingdom. They familiarized the Belgians with their heroic ‘forefathers’ and with their legacy. The meaning and message of these pantheons were easily accessible. The sculpted, painted and written specimens of the genre could adopt various forms and could be composed according to different schemes. The national heroes were gathered either in a series of individual portraits or in a single group portrait. Often they displayed a hierarchic structure. The discussions about the medium concerned the selection and selectivity of the series and compositions: who could be allowed to enter the Hall of Fame of the nation, and was it not too crowded? Moreover, the excessive growth of the number of pantheons threatened to undermine their effectiveness. King Leopold II made various attempts to raise one National Monument in honour of the heroes of the nation, after the exemple of the Walhalla of Ludwig I of Bavaria. But the pantheon had lost prestige by the end of the nineteenth century. As an expression of the historical culture it had become marginal. Only within the framework of the debate on the ‘layered’ Belgian nationality, did a certain revival occur. In the year 1930, the Flemish subnation established its own pantheons.

    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

  2. Long-term drug administration in the adult zebrafish using oral gavage for cancer preclinical studies

    Directory of Open Access Journals (Sweden)

    Full Text Available Zebrafish are a major model for chemical genetics, and most studies use embryos when investigating small molecules that cause interesting phenotypes or that can rescue disease models. Limited studies have dosed adults with small molecules by means of water-borne exposure or injection techniques. Challenges in the form of drug delivery-related trauma and anesthesia-related toxicity have excluded the adult zebrafish from long-term drug efficacy studies. Here, we introduce a novel anesthetic combination of MS-222 and isoflurane to an oral gavage technique for a non-toxic, non-invasive and long-term drug administration platform. As a proof of principle, we established drug efficacy of the FDA-approved BRAFV600E inhibitor, Vemurafenib, in adult zebrafish harboring BRAFV600E melanoma tumors. In the model, adult casper zebrafish intraperitoneally transplanted with a zebrafish melanoma cell line (ZMEL1 and exposed to daily sub-lethal dosing at 100 mg/kg of Vemurafenib for 2 weeks via oral gavage resulted in an average 65% decrease in tumor burden and a 15% mortality rate. In contrast, Vemurafenib-resistant ZMEL1 cell lines, generated in culture from low-dose drug exposure for 4 months, did not respond to the oral gavage treatment regimen. Similarly, this drug treatment regimen can be applied for treatment of primary melanoma tumors in the zebrafish. Taken together, we developed an effective long-term drug treatment system that will allow the adult zebrafish to be used to identify more effective anti-melanoma combination therapies and opens up possibilities for treating adult models of other diseases.

  3. 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.

    Full text of publication follows. ITER steady-state operation aims at demonstrating fully non-inductive plasma operation at a moderate fusion power multiplication factor (Q) of about 5, for long burn durations of up to 3000 s. In this work, this operational capability is studied using an advanced free-boundary transport simulation code, CORSICA [1-3], including relevant physics and engineering constraints. The tokamak discharge modelling capability of the CORSICA code has been improved by integrating realistic source modules for heating and current drive and a parameterized EPED1 pedestal model. The electro-magnetic ITER machine description is computed using the recent design parameters and the latest source configurations are taken into account. This work has been performed to study the feasibility of the ITER steady-state operation. Although the evolution of internal transport barriers (ITBs) are not yet included in this study, a higher energy confinement over the H-mode confinement (H98>1) is assumed by maintaining a reversed safety factor (q) profile during the flat-top phase. This paper presents several ITER steady-state operation scenarios, including a reference 9 MA case, and also suggests a potential approach for achieving fully non-inductive ITER steady-state operation with Q>5.

  6. Community Needs Assessment After Microcystin Toxin Contamination of a Municipal Water Supply - Lucas County, Ohio, September 2014. (United States)

    McCarty, Carolyn L; Nelson, Leigh; Eitniear, Samantha; Zgodzinski, Eric; Zabala, Amanda; Billing, Laurie; DiOrio, Mary


    On August 1, 2014, routine testing at the Collins Park Water Treatment Plant in Lucas County, Ohio, revealed microcystin toxin levels in drinking water had reached 3.19 μg/L, surpassing the Ohio Environmental Protection Agency (EPA) drinking water advisory threshold of 1.0 μg/L. Microcystin is a hepatoxin released by cyanobacteria in certain harmful algal blooms. Exposure to microcystin has been associated with gastrointestinal and hepatic illness in both humans and animals (1-3). On August 2, a do-not-drink advisory was issued, warning community members not to drink, boil, or use the water for cooking or brushing teeth. Public health officials used traditional and social media outlets to disseminate public health messages to affected communities. On August 4, 2014, the advisory was lifted after multiple water samples confirmed microcystin toxin levels had dropped below the advisory threshold. To assess communication strategies, water exposure, and household needs, the Ohio Department of Health (ODH) and Toledo-Lucas County Health Department (TLCHD) conducted a Community Assessment for Public Health Emergency Response (CASPER) in Lucas County. Most households (88.1%) reported hearing about the advisory the morning it was issued, but 11% reported drinking and 21% reported brushing teeth with municipal water during the advisory. Household members reported physical (16%) and mental (10%) health concerns that they believed were related to the advisory and activity disruptions including temporarily staying outside of the home (6%) during the advisory and continued use of alternative water sources after the advisory was lifted (82%). During a do-not-drink advisory, governmental agencies and community partners need to engage in joint prevention and response efforts to decrease water exposure and prevent activity disruptions.

  7. Injuries and Traumatic Psychological Exposures Associated with the South Napa Earthquake - California, 2014. (United States)

    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.

  8. Performance Analysis of a Hardware Implemented Complex Signal Kurtosis Radio-Frequency Interference Detector (United States)

    Schoenwald, Adam J.; Bradley, Damon C.; Mohammed, Priscilla N.; Piepmeier, Jeffrey R.; Wong, Mark


    Radio-frequency interference (RFI) is a known problem for passive remote sensing as evidenced in the L-band radiometers SMOS, Aquarius and more recently, SMAP. Various algorithms have been developed and implemented on SMAP to improve science measurements. This was achieved by the use of a digital microwave radiometer. RFI mitigation becomes more challenging for microwave radiometers operating at higher frequencies in shared allocations. At higher frequencies larger bandwidths are also desirable for lower measurement noise further adding to processing challenges. This work focuses on finding improved RFI mitigation techniques that will be effective at additional frequencies and at higher bandwidths. To aid the development and testing of applicable detection and mitigation techniques, a wide-band RFI algorithm testing environment has been developed using the Reconfigurable Open Architecture Computing Hardware System (ROACH) built by the Collaboration for Astronomy Signal Processing and Electronics Research (CASPER) Group. The testing environment also consists of various test equipment used to reproduce typical signals that a radiometer may see including those with and without RFI. The testing environment permits quick evaluations of RFI mitigation algorithms as well as show that they are implementable in hardware. The algorithm implemented is a complex signal kurtosis detector which was modeled and simulated. The complex signal kurtosis detector showed improved performance over the real kurtosis detector under certain conditions. The real kurtosis is implemented on SMAP at 24 MHz bandwidth. The complex signal kurtosis algorithm was then implemented in hardware at 200 MHz bandwidth using the ROACH. In this work, performance of the complex signal kurtosis and the real signal kurtosis are compared. Performance evaluations and comparisons in both simulation as well as experimental hardware implementations were done with the use of receiver operating characteristic (ROC

  9. 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.

  10. High Energy Gas Fracturing Test

    Energy Technology Data Exchange (ETDEWEB)

    Schulte, R.


    The Rocky Mountain Oilfield Testing Center (RMOTC) has recently completed two tests of a high-energy gas fracturing system being developed by Western Technologies of Crossville, Tennessee. The tests involved the use of two active wells located at the Naval Petroleum Reserve No. 3 (NPR-3), thirty-five miles north of Casper, Wyoming (See Figure 1). During the testing process the delivery and operational system was enhanced by RMOTC, Western Technologies, and commercial wireline subcontractors. RMOTC has assisted an industrial client in developing their technology for high energy gas fracturing to a commercial level. The modifications and improvements implemented during the technology testing process are instrumental in all field testing efforts at RMOTC. The importance of well selection can also be critical in demonstrating the success of the technology. To date, significant increases in well productivity have been clearly proven in well 63-TPX-10. Gross fluid production was initially raised by a factor of three. Final production rates increased by a factor of six with the use of a larger submersible pump. Well productivity (bbls of fluid per foot of drawdown) increased by a factor of 15 to 20. The above results assume that no mechanical damage has occurred to the casing or cast iron bridge plug which could allow well production from the Tensleep ''B'' sand. In the case of well 61-A-3, a six-fold increase in total fluid production was seen. Unfortunately, the increase is clouded by the water injection into the well that was necessary to have a positive fluid head on the propellant tool. No significant increase in oil production was seen. The tools which were retrieved from both 63-TPX-10 and 61-A-3 indicated a large amount of energy, similar to high gram perforating, had been expended downhole upon the formation face.

  11. 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

  13. Integrating hydraulic equivalent sections into a hydraulic geometry study (United States)

    Jia, Yanhong; Yi, Yujun; Li, Zhiwei; Wang, Zhaoyin; Zheng, Xiangmin


    Hydraulic geometry (HG) is an important geomorphic concept that has played an indispensable role in hydrological analyses, physical studies of streams, ecosystem and aquatic habitat studies, and sedimentology research. More than 60 years after Leopold and Maddock (1953) first introduced the concept of HG, researchers have still not uncovered the physical principles underlying HG behavior. One impediment is the complexity of the natural river cross section. The current study presents a new way to simplify the cross section, namely, the hydraulic equivalent section, which is generalized from the cross section in the "gradually varied flow of an alluvial river" (GVFAR) and features hydrodynamic properties and bed-building laws similar to those of the GVFAR. Energy balance was used to derive the stage Z-discharge Q relationship in the GVFAR. The GVFAR in the Songhua River and the Yangtze River were selected as examples. The data, including measured discharge, river width, water stage, water depth, wet area, and cross section, were collected from the hydrological yearbooks of typical hydrological stations on the Songhua River and the Yangtze River from 1955 to 1987. The relationships between stage Z-discharge Q and cross-sectional area A-stage Z at various stations were analyzed, and "at-a-station hydraulic geometry" (AHG) relationships were obtained in power-law forms. Based on derived results and observational data analysis, the Z-Q and Z-A relationships of AHG were similar to rectangular weir flows, thus the cross section of the GVFAR was generalized as a compound rectangular, hydraulic equivalent cross section. As to bed-building characteristics, the bankfull discharge method and the stage-discharge-relation method were used to calculate the dominant variables of the alluvial river. This hydraulic equivalent section has the same Z-Q relation, Z-A relation, dominant discharge, dominant river width, and dominant water depth as the cross section in the GVFAR. With the

Describes LAP as the methodological basis for understanding the self-adjustment alluvial channels towards MFE. 5. 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.

    Trinajstić, N.


    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

    Ferrari, Katia Regina


    Present study developed a simplified methodology to evaluate the environmental impacts of the wet process of production of ceramic tiles. In order to subsidize the development of the model of environmental evaluation and to achieve a better understanding of the productive process, there were elaborated matrices in which was correlated the stages of the productive system with the respective types and volumes of residues generated. To these matrices there were related the technical norms of the Brazilian Association of Norms and Techniques (ABNT), which determines the sampling methodologies, characterizations, monitoring and treatment of the solid residues and liquid and gaseous effluents; and the pertinent Federal and State Legislations which dispose on the control of the environmental pollution. The evaluation of the environmental impact model here proposed was developed fram the Interaction Matrix of Leopold and from the Risk Matrix proposed by Moura, in which identified the pollutant effects (critical, significant, reduced, marginal) of the stages of this productive process. The validation of these results was obtained through the accomplishment of analytic assays in the used raw materials and in the residues generated in the productive process. The results of the chemical analyses reinforce that the positive toxicity in the liquid effluent is related with the chemical composition of the synthetic raw material used in the decoration. It was concluded that the solid residues that more damage cause to the environment are those coming from the enamel and dying preparation and application sections. Concomitantly, it was performed a study of characterization of the natural raw materials and of the product, using different techniques as fluorescence X ray, differential thermal analysis with thermogravimetry, scanning electron microscopy and X ray diffraction, in order to understand the interactions of the components of the mass of the ceramic body, during the stage of

    Full Text Available The Concert Hall is reached through the entrance vestibule, cloak room area and large foyer from which a spacious patio, treated as landscape, can be seen. Thus, the outside environment is incorporated Into the inside environment which lends great beauty to the unit formed by the entrance area and the foyer while at the same time it establishes a clear separation of the different functions that take place Inside. On this floor there is also another concert room, smaller in size as it holds only 500 persons, with its own foyer, bar, cloak room, etc.; a wide restaurant area, which can be widened towards the outdoor terraces; kitchens; meeting and rehearsal rooms, etc. With regards to the surrounding zone, the green areas existing or created around the Concert Hall help to maintain and emphasize its park like character, already helped by the «Leopold Forest» within which the site is found.El acceso a la Sala de Conciertos se realiza a través del vestíbulo de entrada, zona de guardarropas y gran «foyer» —en comunicación visual con un amplio patio tratado paisajísticamente, lográndose una incorporación del ambiente exterior, al del interior—, lo que da una gran vistosidad al conjunto formado por la zona de entrada y foyer, al mismo tiempo que establece una clara separación de las diferentes funciones que se desarrollan en el interior. En esta planta hay, además, otra sala de conciertos más pequeña —capaz para 500 personas—, con sus correspondientes foyer, bar, guardarropas, etc.; una amplia zona de restaurante —ampliable hacia las terrazas exteriores—; cocinas; salas de juntas, de ensayos; etc. Respecto al entorno exterior, las zonas verdes existentes o creadas alrededor de la Sala de Conciertos contribuyen a mantener y acusar el carácter de «parque», que ya ofrecía el «Bosque de Leopoldo» —lugar del emplazamiento—.

  20. 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

  1. 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

  2. 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 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.

  4. Progress in the Rotational Analysis of the Ground and Low-Lying Vibrationally Excited States of Malonaldehyde (United States)

    Goudreau, E. S.; Tokaryk, Dennis W.; Ross, Stephen Cary; Billinghurst, Brant E.


    Despite being an important prototype molecule for intramolecular proton tunnelling, the far-IR spectrum of the internally hydrogen-bonded species malonaldehyde (C_3O_2H_4) is not yet well understood. In the talk I gave at the ISMS meeting in 2015 I discussed the high-resolution spectra we obtained at the Canadian Light Source synchrotron in Saskatoon, Saskatchewan. These spectra include a number of fundamental vibrational bands in the 100-2000 cm-1 region. In our efforts to analyze these bands we have noticed that our ground state combination differences show a large drift (up to an order of magnitude larger than our experimental error) away from those calculated using constants established by Baba et al., particularly in regions of high J (above 30) and low Ka (below 5). An examination of the previous microwave and far-IR studies reveals that this region of J-Ka space was not represented in the lines that Baba et al. used to generate the values for their fitting parameters. By including our own measurements in the fitting, we were able to improve the characterization of the ground state so that it is now consistent with all of the existing data. This characterization now covers a much larger range of J-Ka space and has enabled us to make significant progress in analyzing our far-IR synchrotron spectra. These include an excited vibrational state at 241 cm-1 as well as several states split by the tunnelling effect at higher wavenumber. T. Baba, T. Tanaka, I. Morino, K. M. T. Yamada, K. Tanaka.

  6. 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

  8. Up-regulation of the mammalian target of rapamycin complex 1 subunit Raptor by aldosterone induces abnormal pulmonary artery smooth muscle cell survival patterns to promote pulmonary arterial hypertension (United States)

    Aghamohammadzadeh, Reza; Zhang, Ying-Yi; Stephens, Thomas E.; Arons, Elena; Zaman, Paula; Polach, Kevin J.; Matar, Majed; Yung, Lai-Ming; Yu, Paul B.; Bowman, Frederick P.; Opotowsky, Alexander R.; Waxman, Aaron B.; Loscalzo, Joseph; Leopold, Jane A.; Maron, Bradley A.


    Activation of the mammalian target of rapamycin complex 1 (mTORC1) subunit Raptor induces cell growth and is a downstream target of Akt. Elevated levels of aldosterone activate Akt, and, in pulmonary arterial hypertension (PAH), correlate with pulmonary arteriole thickening, which suggests that mTORC1 regulation by aldosterone may mediate adverse pulmonary vascular remodeling. We hypothesized that aldosterone-Raptor signaling induces abnormal pulmonary artery smooth muscle cell (PASMC) survival patterns to promote PAH. Remodeled pulmonary arterioles from SU-5416/hypoxia-PAH rats and monocrotaline-PAH rats with hyperaldosteronism expressed increased levels of the Raptor target, p70S6K, which provided a basis for investigating aldosterone-Raptor signaling in human PASMCs. Aldosterone (10−9 to 10−7 M) increased Akt/mTOR/Raptor to activate p70S6K and increase proliferation, viability, and apoptosis resistance in PASMCs. In PASMCs transfected with Raptor–small interfering RNA or treated with spironolactone/eplerenone, aldosterone or pulmonary arterial plasma from patients with PAH failed to increase p70S6K activation or to induce cell survival in vitro. Optimal inhibition of pulmonary arteriole Raptor was achieved by treatment with Staramine-monomethoxy polyethylene glycol that was formulated with Raptor-small interfering RNA plus spironolactone in vivo, which decreased arteriole muscularization and pulmonary hypertension in 2 experimental animal models of PAH in vivo. Up-regulation of mTORC1 by aldosterone is a critical pathobiologic mechanism that controls PASMC survival to promote hypertrophic vascular remodeling and PAH.—Aghamohammadzadeh, R., Zhang, Y.-Y., Stephens, T.

  10. 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.

  11. Stratigraphic cross sections of the Niobrara interval of the Cody Shale and associated rocks in the Wind River Basin, central Wyoming (United States)

    Finn, Thomas M.


    The Wind River Basin in Wyoming is one of many structural and sedimentary basins that formed in the Rocky Mountain foreland during the Laramide orogeny. The basin is nearly 200 miles long, 70 miles wide, and encompasses about 7,400 square miles in central Wyoming. The basin is bounded by the Washakie Range, Owl Creek uplift, and southern Bighorn Mountains on the north, the Casper arch on the east, the Granite Mountains on the south, and Wind River Range on the west.Many important conventional oil and gas fields producing from reservoirs ranging in age from Mississippian through Tertiary have been discovered in this basin. In addition, an extensive unconventional overpressured basin-centered gas accumulation has been identified in Cretaceous and Tertiary strata in the deeper parts of the basin. It has long been suggested that various Upper Cretaceous marine shales, including the Cody Shale, are the principal hydrocarbon source rocks for many of these accumulations. With recent advances and success in horizontal drilling and multistage fracture stimulation, there has been an increase in exploration and completion of wells in these marine shales in other Rocky Mountain Laramide basins that were traditionally thought of only as hydrocarbon source rocks.The two stratigraphic cross sections presented in this report were constructed as part of a project carried out by the U.S. Geological Survey to characterize and evaluate the undiscovered continuous (unconventional) oil and gas resources of the Niobrara interval of the Upper Cretaceous Cody Shale in the Wind River Basin in central Wyoming. The primary purpose of the cross sections is to show the stratigraphic relationship of the Niobrara equivalent strata and associated rocks in the lower part of the Cody Shale in the Wind River Basin. These two cross sections were constructed using borehole geophysical logs from 37 wells drilled for oil and gas exploration and production, and one surface section along East Sheep Creek

  12. 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

  13. Demonstration of Technologies for Remote and in Situ Sensing of Atmospheric Methane Abundances - a Controlled Release Experiment (United States)

    Aubrey, A. D.; Thorpe, A. K.; Christensen, L. E.; Dinardo, S.; Frankenberg, C.; Rahn, T. A.; Dubey, M.


    It is critical to constrain both natural and anthropogenic sources of methane to better predict the impact on global climate change. Critical technologies for this assessment include those that can detect methane point and concentrated diffuse sources over large spatial scales. Airborne spectrometers can potentially fill this gap for large scale remote sensing of methane while in situ sensors, both ground-based and mounted on aerial platforms, can monitor and quantify at small to medium spatial scales. The Jet Propulsion Laboratory (JPL) and collaborators recently conducted a field test located near Casper, WY, at the Rocky Mountain Oilfield Test Center (RMOTC). These tests were focused on demonstrating the performance of remote and in situ sensors for quantification of point-sourced methane. A series of three controlled release points were setup at RMOTC and over the course of six experiment days, the point source flux rates were varied from 50 LPM to 2400 LPM (liters per minute). During these releases, in situ sensors measured real-time methane concentration from field towers (downwind from the release point) and using a small Unmanned Aerial System (sUAS) to characterize spatiotemporal variability of the plume structure. Concurrent with these methane point source controlled releases, airborne sensor overflights were conducted using three aircraft. The NASA Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) participated with a payload consisting of a Fourier Transform Spectrometer (FTS) and an in situ methane sensor. Two imaging spectrometers provided assessment of optical and thermal infrared detection of methane plumes. The AVIRIS-next generation (AVIRIS-ng) sensor has been demonstrated for detection of atmospheric methane in the short wave infrared region, specifically using the absorption features at ~2.3 μm. Detection of methane in the thermal infrared region was evaluated by flying the Hyperspectral Thermal Emission Spectrometer (Hy

    Directory of Open Access Journals (Sweden)

    Piotr Musiałek


    Full Text Available Atherosclerotic carotid artery stenosis (CS continues to be a common cause of acute ischaemic stroke. Optimised medical therapy (OMT, the first-line treatment modality in CS, may reduce or delay – but it does not abolish – CS-related strokes. As per current AHA/ASA and ESC/ESVS/ESO guidelines, carotid artery stenting (CAS is a less-invasive alternative to carotid endarterectomy (CEA for CS revascularisation in primary and secondary stroke prevention. Ten-year follow-up from the CREST trial in patients with symptomatic and asymptomatic CS confirmed equipoise of CAS and CEA in the primary endpoint. Nevertheless CAS – using a widely open-cell, first-generation stent and first-generation (distal/filter neuroprotection – has been criticised for its relative excess of (mostly minor strokes by 30 days, a significant proportion of which were post-procedural. Atherosclerotic plaque protrusion through conventional carotid stent struts, confirmed on intravascular imaging, has been implicated as a leading mechanism of the relative excess of strokes with CAS vs. CEA, including delayed strokes with CAS. Different designs of mesh-covered carotid stents have been developed to prevent plaque prolapse. Several multi-centre/multi-specialty clinical studies with CGurad MicroNet-Covered Embolic Prevention Stent System (EPS and RoadSaver/Casper were recently published and included routine DW-MRI cerebral imaging peri-procedurally and at 30 days (CGuard EPS. Data from more than 550 patients in mesh-covered carotid stent clinical studies to-date show an overall 30-day complication rate of ~1% with near-elimination of post-procedural events. While more (and long-term evidence is still anticipated, these results – taken together with optimised intra-procedural neuroprotection in CAS (increased use of proximal systems including trans-carotid dynamic flow reversal and the positive 12-month mesh-covered stent data reports in 2017 – are transforming the carotid

  15. 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

  16. Study of Electrical Activity in Martian Dust Storms with the Deep Space Network antennas (United States)

    Martinez, S.; Kuiper, T. B. H.; Majid, W. A.; Garcia-Miro, C.; Tamppari, L. K.; Renno, N. O.; Ruf, C.; Trinh, J. T.


    Evidence for non-thermal emission produced by electrostatic discharges in a deep Martian dust storm has been reported by Ruf et al. 2009 [1]. Such discharges had been detected with an innovative kurtosis detector installed in a 34m radio telescope of the Deep Space Network (DSN) in June of 2006. The kurtosis (the fourth central moment of the signal normalized by the square of the second central moment) is extremely sensitive to the presence of non-thermal radiation, but is insensitive to variations in the intensity of the thermal radiation and instrument gain. The non-thermal radiation was detected while a 35 Km deep Martian dust storm was within the field of view of the radio telescope and presented signatures of modulation by the Martian Schumann Resonance. Encouraged by this discovery, several attempts have been made within the DSN to confirm the detection using the R&D antenna (DSS-13) and other antennas in the Madrid and Goldstone complexes, but using a very limited receiver, in terms of recorded data rates, the Very Long Baseline Interferometry (VLBI) Science Receiver (VSR). We are planning to initiate an extensive monitoring of Mars emission in a noninterfering basis while our antennas are tracking various Mars probes, using the Wideband Very Long Baseline Interferometry (VLBI) Science Receiver (WVSR). The WVSR is a very flexible open-loop digital backend that is used for radio science and spacecraft navigation support in the DSN. This instrument allows us to sample a larger bandwidth than with previously used detectors. The processing to look for the kurtosis signature will be performed in software, limited only by the computer capacity. Additionally there are plans to develop an even more powerful custom-built detector based in CASPER technology and Graphic Processing Units for enhance computational power. This contribution will describe how we plan to select the target Mars tracking passes from the DSN schedule. An automated process will generate

  17. 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

  18. 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.

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

    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

His journey throughout Spain (1681-1682 formed part of his European “grand tour” (1679-1682. Before setting off on this trip, Count Humprecht instructed his son to write a diary in the languages of the lands he visited. Thanks to satisfying his father’s wishes, Heřman Jakub became the author of an exceptional diary, which not only records his entire European itinerary, but is also an interesting linguistic document. The young Černín dedicated most of the space in his diary to describing his meetings with important figures, festivities and historical monuments. Although some erudition can be observed in his knowledge of art, he cannot be considered a specialist or an art expert. What most attracted his attention were works of art and architecture whose significance was already well known, and which he had heard about through his father, his tutor or occasionally through local guides and travel books. The whole of Černín’s Spanish journey was marked by his special interest in architecture. While he was able to recognise the value and quality of paintings and sculptures, he noted specific works and names of artists only sporadically in his diary.

  2. 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

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.

  8. Geology and ground-water resources of Platte County, Wyoming, with a section on Chemical quality of the water (United States)

    Morris, D.A.; Babcock, H.M.; Langford, R.H.


    Platte County, Wyo., has an area of 2,114 square miles and, in 1950, had a population of 7,925; it lies within parts of two major physiographic provinces, the northern extension of the Southern Rocky Mountains and the northwestern part of the Great Plains. The Laramie Range and related structures lie along the western margin of the county and constitute the eastern limit of the Rocky Mountain Front Range. The High Plains section of the Great Plains province extends eastward from the Laramie Range over the remainder of the county. The original surface of the High Plains has been deeply eroded, and in the northeastern part of the county it is broken by the broad uplifted structural platform of the Hartville Hills. The North Platte River and its tributaries have entrenched their channels as much as 1,000 feet into the plains, leaving wide, very flat intervalley areas that are interrupted by a few isolated buttes and outlying ridges. Well-defined terraces, locally called the Wheatland Flats, have been formed in central Platte County. The climate is semiarid, the average annual precipitation being about 15 inches. Farming and stockraising are the principal occupations in the county. Most of the rocks exposed in the county are of Tertiary and Quaternary age, although rocks as old as Precambrian crop out locally. The Arikaree and Brule formations and younger deposits, including Tertiary ( ?) deposits (undifferentiated) and terrace, flood-plain, and other alluvial deposits, underlie more than two-thirds of the county. Mesozoic, Paleozoic, and Precambrian rocks crop out in the other third and underlie the younger rocks at great depths elsewhere. Small supplies of ground water adequate for domestic and stock use can be obtained from shallow wells in the Casper, Hartville, Cloverly, Brule, and Arikaree formations and in the terrace and flood-plain deposits. Small to moderate amounts of ground water can be obtained from the 'Converse sand' of the Hartville formation. Several

    -central Wyoming. Similarly, in east-central Wyoming and an adjacent area to the south, Cenomanian strata are disconformably overlain by upper middle and lower upper Turonian strata that probably reflect uplift and erosion in that region during the interim period of middle Turonian time. During later subsidence and a marine transgression, upper Turonian deposits buried Cenomanian beds in areas along the south and east margins of the Bighorn Basin and buried lower middle Turonian beds in much of northern Wyoming. Upper Turonian and lower Coniacian strata are apparently conformable in eastern and southern areas of the basin as well as near Riverton, Kaycee, and Casper in central Wyoming. Upper Turonian strata are absent on the west flank of the Bighorn Basin and in outcrops west of the basin, where middle Turonian beds are disconformably overlain by lower Coniacian beds . The conformable upper Turonian and lower Coniacian beds apparently transgressed an eroded middle Turonian surface in the region, but only Coniacian strata overlie middle Turonian beds on the west side of the basin and areas farther west. Coniacian strata onlap the truncated lower middle Turonian surface west of the basin, indicating a region that had higher elevation possibly resulting from tectonic uplift. In east-central Wyoming and an adjoining region to the south, upper middle Turonian and lower upper Turonian strata are disconformably overlain by lower and middle Coniacian beds. That region apparently was uplifted and eroded during the latest Turonian.

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.

  13. 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

    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. The German prince and first king of the Belgians, Leopold

  15. 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.

  17. Phil Wallace and Theoretical Physics at McGill in the 1950's: A Personal Perspective

    Energy Technology Data Exchange (ETDEWEB)

    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

  18. 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.

  19. Advanced Seismic While Drilling System

    Energy Technology Data Exchange (ETDEWEB)

    Robert Radtke; John Fontenot; David Glowka; Robert Stokes; Jeffery Sutherland; Ron Evans; Jim Musser


    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

    Jordens, H.; Mathelitsch, L.


    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.
