  4. Historical-critical objects and gestures: Hebreia by Fabio Mauri

    Directory of Open Access Journals (Sweden)

    Maria Augusta Vilalba Nunes

    2015-09-01

    Full Text Available In 1971, Italian artist Fabio Mauri produces the performance / installation artwork Ebrea, which emerges a memory of the Shoah through the performatic gestures and sculpture-objects that make up the scene. In Ebrea the time unfolds and bring back to present the memory of a catastrophe. So, over twenty years after the end of the war, why would Mauri up this memory that was getting distant and was beginning to have an unrealistic form? The anachronism of Mauri’s gesture is intrinsically connected to the need of render account to the hidden memories that don’t leave him and whose tracks, in his opinion, should not be erased from history.

  8. Ecological factors regulating brood attendance patterns of the western sandpiper calidris mauri

    Science.gov (United States)

    2009-01-01

    Parental brood attendance patterns vary greatly among shorebird species. For monogamous calidridine species, biparental care with female-first brood departure is most common. It is believed that adult sandpipers balance potential individual survival costs associated with extended parental care against the benefit gained by their brood of prolonged parental care. These costs and benefits are difficult to quantify and factors affecting the termination of parental brood attendance are unclear. We compared clutch size, nesting phenology, and parental attendance patterns of Western Sandpipers Calidris mauri at Nome and Kanaryarmiut, Alaska, sites separated by three degrees of latitude. The sites differed in breeding density and duration of breeding season, but the distribution of clutch sizes did not differ between sites or between nesting attempts. Parental attendance patterns were similar between sites, suggesting that parental attendance is a highly conserved life-history trait in Western Sandpipers. Male Western Sandpipers attended broods longer than females, and the duration of parental attendance decreased at a similar rate for both sexes as the season progressed. Male and female Western Sandpipers undertake differential migrations to their non-breeding grounds, with males typically settling at more northerly locations and females at more southerly sites, a migration pattern shared by certain other monogamous calidridine species. These same species exhibit similar parental brood attendance patterns, suggesting the strong role of overall migration distance in shaping the expression of parental attendance behaviours. A contrast of more geographically disjunct sites coupled with a better understanding of the migratory connectivity between Western Sandpiper breeding and non-breeding populations would elucidate the role of cross-seasonal effects on parental brood attendance decisions. ?? 2009 British Ornithologists' Union.

  9. Flight performance of western sandpipers, Calidris mauri, remains uncompromised when mounting an acute phase immune response.

    Migratory birds have been implicated in the spread of some zoonotic diseases, but how well infected individuals can fly remains poorly understood. We used western sandpipers, Calidris mauri, to experimentally test whether flight is affected when long-distance migrants are mounting an immune response and whether migrants maintain immune defences during a flight in a wind tunnel. We measured five indicators of innate immunity in 'flown-healthy' birds (flying in a wind tunnel without mounting an immune response), 'flown-sick' birds (flying while mounting an acute phase response, which is part of induced innate immunity), and a non-flying control group ('not-flown'). Voluntary flight duration did not differ between flown-healthy and flown-sick birds, indicating that mounting an acute phase response to simulated infection did not hamper an individual's ability to fly for up to 3 h. However, in comparison to not-flown birds, bacterial killing ability of plasma was significantly reduced after flight in flown-sick birds. In flown-healthy birds, voluntary flight duration was positively correlated with bacterial killing ability and baseline haptoglobin concentration of the blood plasma measured 1-3 weeks before experimental flights, suggesting that high quality birds had strong immune systems and greater flight capacity. Our findings indicate that flight performance is not diminished by prior immune challenge, but that flight while mounting an acute phase response negatively affects other aspects of immune function. These findings have important implications for our understanding of the transmission of avian diseases, as they suggest that birds can still migrate while fighting an infection.

  10. A new species of Tarracoblaniulus Mauriès & Vicente, 1977: description, postembryonic development, life cycle, and spatial distribution (Diplopoda, Julida, Blaniulidae

    Directory of Open Access Journals (Sweden)

    Martínez, H.

    2009-06-01

    Full Text Available Tarracoblaniulus phantasmanus n. sp. is described from Tarragona province, Spain and compared with the only known other species known in the genus, T. lagari Mauriès & Vicente, 1977, from which it differs mainly in having only 5, instead of 15 or more, straight spines on the posterior gonopod. The female vulva (unknown in T. lagari is very different from all known blaniulid vulvae. Based on a large number of specimens, the postembryonic development (euanamorphosis from stadium II onward is described. This is highly variable, with three to six apodous body rings in stadium IV, which is the most variable number so far recorded in Blaniulidae. Accordingly, specimens beyond stadium VIII could not be assigned to a specific stadium. At least some males are morphologically distinguishable in stadium IV, morphologically mature males appear in stadium VIII, possibly already in stadium VII. The life cycle of the new species is tentatively suggested to involve at least three years. The monthly mean density of the total population was 28.82 ind/m2 across the whole soil profile. Statistically significant differences in density values between months and Spearman’s rank correlation analyses between the monthly mean values of density and temperature show that T. phantasmanus presents a maximum density in the coldest months and a minimum one in the summer. Significant differences between monthly mean densities of different soil levels and the Usher index values show that during the spring and summer T. phantasmanus is concentrated in the mineral horizon A. In autumn, during winter and up to early spring, the population shows a clear tendency to move up towards horizon H and horizon L/F. Concerning horizontal distribution, Morisita index monthly values for each of the horizons indicate that the species is distributed in patches.Se describe Tarracoblaniulus phantasmanus n. sp., especie encontrada en la provincia de Tarragona (España, y se compara con la única

    Scoping studies were designed to determine if double-crested cormorants (Phalacocorax auritus), laughing gulls (Leucophaues atricilla), homing pigeons (Columba livia) and western sandpipers (Calidris mauri) that were gavaged with a mixture of artificially weathered MC252 oil and food for either a single day or 4-5 consecutive days showed signs of oil toxicity. Where volume allowed, samples were collected for hematology, plasma protein electrophoresis, clinical chemistry and electrolytes, oxidative stress and organ weigh changes. Double-crested cormorants, laughing gulls and western sandpipers all excreted oil within 30min of dose, while pigeons regurgitated within less than one hour of dosing. There were species differences in the effectiveness of the dosing technique, with double-crested cormorants having the greatest number of responsive endpoints at the completion of the trial. Statistically significant changes in packed cell volume, white cell counts, alkaline phosphatase, alanine aminotransferase, creatine phosphokinase, gamma glutamyl transferase, uric acid, chloride, sodium, potassium, calcium, total glutathione, glutathione disulfide, reduced glutathione, spleen and liver weights were measured in double-crested cormorants. Homing pigeons had statistically significant changes in creatine phosphokinase, total glutathione, glutathione disulfide, reduced glutathione and Trolox equivalents. Laughing gulls exhibited statistically significant decreases in spleen and kidney weight, and no changes were observed in any measurement endpoints tested in western sandpipers.

    Accurate measurements of the heavy-metal contents in polluted areas are required to assess the potential ecological risks in these areas. Chemical and biological indicators are of interest when they provide information about the concentration and accumulation of heavy metals in the environment. These studies were conducted in order to investigate heavy-metal accumulation and the effect on Conocarpus (Conocarpus Erectus) on roadside trees. The total content of Pb and Mn was determined using atomic absorption spectrophotometry, AAS. The present results showed variations that indicate both the concerned species have the highest concentration in all the sampling areas near the road. According to the results present study, the average concentration of Pb and Mn are 10.576+3.482 micro g/gm and 91.977+ 30.030 micro g/gm respectively. The results showed that the plant demonstrated a physiological response to the heavy-metal pollution, which suggests that roadside plants are indicators of heavy-metal accumulation and the effect on the environment.

    Full Text Available Oedipus is the “why?” man. And what journey more than Oedipus’s is the paradigm of effort, sorrow and devastating courage for achieving the truth? “Let everything take its course as it is supposed to, and let it destroy me, but light must be shed, for I want to know who I am”. This is what Oedipus shouts from the deepest darkness of himself, but above all he shouts that to all of us. Even if man will be submitted to Gods, Destiny, Fate, Society (everyone can provide the interpretation that best suits him, let’s remind ourselves that knowledge is the first act of revolution and independence; to know is already to do! In Sophocles’s tragedies, Oedipus Rex and Oedipus at Colonus, the “fable” of Oedipus searching for the truth is recounted poetically and in its completeness. Those tragedies represent the sublime lamentation on the human condition in its quest for the truth. Oedipus, despite its tortuous path, remains always a man, not a god neither a saint, and that is what makes him similar to all of us. With his long journey, a secular via crucis, Oedipus not only tells us his story, but the story of Man.

  5. Obituary: Maurice M. Shapiro, 1915-2008

    Science.gov (United States)

    Yodh, Gaurang B.

    2009-01-01

    Maurice Shapiro was an outstanding scientist and educator whose contributions spanned a range of fields: He was the leader of the "Water Effects" group (study of underwater explosions) within the Los Alamos Ordnance Division in the Manhattan project during World War II; he witnessed the Trinity test and there "shared a blanket with Hans Bethe." Shapiro understood the nature of the new weapons and helped to form the Association of Los Alamos Scientists [ALAS] to lobby for a civilian atomic-energy commission. (He was chair of ALAS in 1946.) He also worked at Oak Ridge on design of a power reactor just after the war (similar to those used in naval vessels). In 1949 Shapiro joined the Naval Research Laboratory's nuclear physics division, where he started a new program in high-energy physics and cosmic rays, his primary interest throughout his life. In 1977, he founded the International School of Cosmic-Ray Astrophysics in Erice, Italy, where many outstanding scientists in the field were students at early stages of their career. He served as director of this school until his death. Shapiro was interested in understanding the origin, acceleration, and propagation of cosmic rays and the role of high energy neutrinos and their detection. He played a major role in starting the field of high-energy neutrino astronomy. Maury, so of J. Simon Werner and Miriam Rivka, was born in Jerusalem on 13 November 1915. His father never returned home from World War I, and his mother married Rabbi Osher Shapiro two years later. The family migrated to Chicago, Illinois, during the early 1920s. Maury's given name was Moishe Mendel Werner. The only father he knew was Rabbi Shapiro, hence the origin of the name we know him by. His parents had planned a theological career for him; however, Maury opted for the study of Physics at the University of Chicago. He did his Ph.D. with Arthur Compton (1942) using early emulsions exposed at Mount Evans--both emulsions on glass plates and stripped

  6. Dreaming scientists and scientific dreamers: Freud as a reader of French dream literature.

    Science.gov (United States)

    Carroy, Jacqueline

    2006-03-01

    The argument of this paper is to situate The Interpretation of Dreams within an historical context. It is, therefore, impossible to believe Freud entirely when he staged himself in his letters to Fliess as a mere discoverer. In reality Freud also felt he belonged to a learned community of dream specialists, whom I call "dreaming scientists" and "scientific dreamers." Instead of speaking, as Ellenberger does, in terms of influence, I will be offering as an example a portrait of Freud as a reader of two French authors, Maury, and indirectly, Hervey de Saint-Denys. I will analyze how Freud staged himself as replacing Maury and dreaming sometimes like Hervey de Saint-Denys. My premise in this work is that we must forget Freud, in order to adventure into a learned dream culture peculiar to the nineteenth century. Only afterwards can we come back to Freud and place him in this context as a creative heir.

  12. The Three Gorges Project: How sustainable?

    Science.gov (United States)

    2012-08-01

    SummaryIn 1984 the Government of China approved the decision to construct the Three Gorges Dam Project, the largest project since the Great Wall. The project had many barriers to overcome, and the decision was made at a time when sustainability was a relatively unknown concept. The decision to construct the Three Gorges Project remains contentious today, especially since Deputy Director of the Three Gorges Project Construction Committee, Wang Xiaofeng, stated that "We absolutely cannot relax our guard against ecological and environmental security problems sparked by the Three Gorges Project" (Bristow, 2007; McCabe, 2007). The question therefore was posed: how sustainable is the Three Gorges Project? Conventional approaches to sustainability assessment tend to use monetary based assessment aligned to triple bottom line thinking. That is, projects are evaluated as trade-offs between economic, environmental and social costs and benefits. The question of sustainability is considered using such a traditional Cost-Benefit Analysis approach, as undertaken in 1988 by a CIPM-Yangtze Joint Venture, and the Mauri Model Decision Making Framework (MMDMF). The Mauri Model differs from other approaches in that sustainability performance indicators are considered independently from any particular stakeholder bias. Bias is then introduced subsequently as a sensitivity analysis on the raw results obtained. The MMDMF is unique in that it is based on the Māori concept of Mauri, the binding force between the physical and the spiritual attributes of something, or the capacity to support life in the air, soil, and water. This concept of Mauri is analogous to the Chinese concept of Qi, and there are many analogous concepts in other cultures. It is the universal relevance of Mauri that allows its use to assess sustainability. This research identified that the MMDMF was a strong complement to Cost-Benefit Analysis, which is not designed as a sustainability assessment tool in itself. The

    We present an implementation in a linear-scaling density-functional theory code of an electronic enthalpy method, which has been found to be natural and efficient for the ab initio calculation of finite systems under hydrostatic pressure. Based on a definition of the system volume as that enclosed within an electronic density isosurface [M. Cococcioni, F. Mauri, G. Ceder, and N. Marzari, Phys. Rev. Lett.94, 145501 (2005)], it supports both geometry optimizations and molecular dynamics simulations. We introduce an approach for calibrating the parameters defining the volume in the context of geometry optimizations and discuss their significance. Results in good agreement with simulations using explicit solvents are obtained, validating our approach. Size-dependent pressure-induced structural transformations and variations in the energy gap of hydrogenated silicon nanocrystals are investigated, including one comparable in size to recent experiments. A detailed analysis of the polyamorphic transformations reveals three types of amorphous structures and their persistence on depressurization is assessed.

    The density matrix divide-and-conquer technique for the solution of Kohn-Sham density functional theory has been implemented within the framework of the SIESTA methodology. Implementation details are provided where the focus is on the scaling of the computation time and memory use, in both serial and parallel versions. We demonstrate the linear-scaling capabilities of the technique by providing ground state calculations of moderately large insulating, semiconducting and (near-) metallic systems. This linear-scaling technique has made it feasible to calculate the ground state properties of quantum systems consisting of tens of thousands of atoms with relatively modest computing resources. A comparison with the existing order-N functional minimization (Kim-Mauri-Galli) method is made between the insulating and semiconducting systems

    2017-12-01

    Indigenous Māori have distinct cultural values and perspectives that establish their identity, responsibilities, and rights to manage and use freshwater in New Zealand. Recognition of the 1840 Treaty of Waitangi and its principles has culminated in an array of modern legislation, obligations, national policy statements, statutory requirements, holistic frameworks, and approaches that strengthens Māori participation and authority in resource management and environmental decision-making. We briefly explain indigenous Māori frameworks, knowledge, values, and perspectives used to grow indigenous research and capability, enrich western scientific research, and inform freshwater planning, policy, and management. We will discuss some important methods, indicators, and tools that Māori have developed, or are developing, to support environmental assessment and the monitoring and reporting of freshwater ecosystems, particularly to help sustain and enhance customary values and practice. These tools include, for example, the Cultural Health Index, the Wai Ora Wai Māori assessment tool, the mauri compass, the mauri model, Māori wetlands assessment, kaitiaki tools, taonga assessment, which are being used to build Māori capability and capacity in freshwater sciences and management and to provide innovative approaches based on integrative knowledge systems. Many of these indigenous-led initiatives are now being used next to science and technical approaches at local, regional, and national scale in New Zealand to guide policy and help understand complex and dynamic human-environmental interactions. Māori epistemologies provide a holistic worldview well aligned with current international thinking and approaches that stress the importance of systems thinking and understanding interconnections between sub-component parts; exploring the world and universe within holistic, integrative frameworks; taking into account different perspectives, values, and worldviews, measuring

In a retrospective, case-control study, 275 women with Alzheimer’s disease (AD and 276 control patients from a hospital population were enrolled from July 2007 to December 2010. The AD patients presented with later menopause (P < 0.01, lower occurrence of surgical menopause (P < 0.04, reduced hormone-replacement therapy intake (P < 0.0001, and a longer reproductive life span (P < 0.01, compared to controls. No significant differences were found with respect to age at puberty, number of pregnancies, previous abortions, or contraceptive therapy. A higher education level appeared to have a protective role against the risk of developing AD. In women, menopause and hormone-replacement therapy can differentially modulate the clinical manifestations of AD, but these factors do not play a predictive role in its development.Keywords: Alzheimer’s disease, gender, menopause, hormone-replacement therapy, surgical menopause, education

    Exploring the discrepancy in sex-ratio among interventional cardiologists by analysing the population of the female interventionalist. Despite an increase number of women who graduate from medical school in France during the last generation today, women represent only 24% of all cardiologists and 3% are interventional cardiologists. To face this international gender-based issue of interventional cardiology, committees were established in US (WIN) and recently within the EAPCI: the Women EAPCI chaired by Drs Mehilli and Mauri. In France, the Intervention'Elles committee emerged in order to participate in this concern. As a first initiative, the Intervention'Elles group launched an e-survey to obtain information on the population of French female interventional cardiologists, focused on demography, work patterns, maternity and radiation exposure. Mean age is 40 years old (±7,4), 68% are working in large volume center, 28% have also structural interventional activity. Only 40% have left arm coverage. Despite 80% of French female interventional cardiologists wear personal dosimeters only 45% of them have a dosimetry feedback. Interestingly, even if 54% of women have children (mean: 1.9±1) 28% of them report that childbearing had interfered with their career plan. This questionnaire identifies for the first time the women population in interventional cardiology in France and highlights some of the issues encountered in more detail. This first descriptive step would help to develop strategies for attaining gender equality in interventional cardiology. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2012-01-01

    Full Text Available In the present paper the problem of a polarized cylinder with a small cross-section, which is located at the contact of two horizontal layers with different resistivities, is studied. Such a polarization geometry simulates the self-potential (SP field produced by a horizontal flow at the contact between the two layers. First, the expression of the self potential at the space domain is derived, applying the image technique. Then, the expression for the Fourier transform of the SP anomaly is found and the behavior of the amplitude spectrum is studied. Based on this study, a direct interpretation method at the spatial frequency domain is proposed, in order to calculate the depth of the flow and the reflection coefficient of the stratified medium. Experimentation with a synthetic model shows that the method works well (small deviations between true and calculated values. When the SP curve contains noise, deviations between calculated and true depths are smaller than those between calculated and true reflection coefficients. The proposed method, which is also applied on SP data from a geothermal system (Mauri et al., 2010, may be useful in detecting underground water or heat flows.

    Being Students of Teacher Researcher Experiences (SoTRE) gives students special advantages that most students do not get. Teachers Elizabeth Eubanks and Steve Allen share their knowledge gained via partnerships with Teacher Researcher Experiences (TRE's) such as the National Oceanographic and Atmospheric Administration Teacher at Sea program (NOAA- TAS), Polar TREC (Teachers and Researchers & Exploring & Collaboration), National Science Foundation (NSF) funded researchers, (EARTH) Education and Research: Testing Hypothesis, the RJ Dunlap Marine Conservation Program, C-DEBI (Center for Dark Energy Biosphere Investigations and (STARS) Sending Teachers Aboard Research Ships, The Maury Project and Mate. Students gain special privileges such as understanding unique research ideas, tracking tagged sharks, following daily journals written on location, taking part in cross-continental experiments, tracking real time data, exploring current research via posters or visiting universities. Furthermore, contacts made by a TRE give students an added set of resources. When doing experiments for class or advancing their education or career goals Eubanks and Allen help students connect with scientists. Many students have felt so strongly about the TRE relationship that they have presented at several local and international science conferences. Their message is to encourage scientists to partner with teachers. The benefits of participation in such conferences have included abstract writing and submission, travel, poster creation, oral presentation, networking and personal research presentation, all tools that they will carry with them for a lifetime.

    In 2001, predator exclosures were used to protect nests of the Western Sandpiper (Calidris mauri) in western Alaska. During the exclosure experiment, nest contents in exclosures had significantly higher daily survival rates than control nests, however, late in the study predators began to cue in on exclosures and predate the nest contents. An Arctic Fox (Alopex lagopus) dug under one exclosure and took the newly hatched chicks, and Long-tailed Jaegers (Stercorarius longicaudus) learned to associate exclosures with active nests and repeatedly visited them. The jaegers attempted to gain access to exclosed nests and pursued adult sandpipers as they emerged from the exclosures. The exclosures were removed to reduce potential mortality to adult and young sandpipers, but subsequently, post-exclosure nests had lower daily survival rates than controls during the same time period. Predation of post-exclosure eggs and chicks highlighted the lasting influence of the exclosure treatment on offspring survival because predators probably remembered nest locations. Researchers are urged to use caution when considering use of predator exclosures in areas where jaegers occur.

These cases were observed during an outbreak in the Paris area. Despite similar blood levels of thyroid hormones, their clinical presentation and outcome were very different. One patient developed febrile confusion and died from malignant hyperthermia. The second one had progressive confusion requiring mechanical plasma exchange therapy and had a favorable outcome. The third one had very moderate symptoms. These exceptional observations raise several issues concerning diagnosis, physiopathology and treatment of thyrotoxicosis factitia.Keywords: thyrotoxicosis, dietary pills, thyroxin

    Full Text Available Chiraziulus is a highly disjunct, hitherto monotypic genus of cambalid millipedes, geographically isolated in Iran by more than 7000 km from its presumed closest relatives in East Asia and North America. Recent fieldwork in caves of Iran has provided several specimens of this genus, allowing the description of Chiraziulus troglopersicus sp. nov. The intraspecific variability of the type species, C. kaiseri Mauriès, 1983, is illustrated with scanning electron micrographs. Chiraziulus is characterized by exceedingly long microtrichose gonopod flagella which from their insertion points on the posterior face of the anterior gonopod coxites first point distad instead of basad or basad-posteriad as in most other flagelliferous Cambalidea (and Julida, then traverse a groove on the mesal surface of the anterior gonopod coxites, making a full (360° loop. The same feature is also illustrated for the first time in the genus Cambala. The patterns and prevalence of the infection with a species of ectoparasitic fungus of the genus Rickia (order Laboulbeniales in the type material of C. kaiseri is described. An updated review of the cave-adapted fauna of Iran is given.

    Full Text Available In this work we present a revision of the genus Ommatoiulus Latzel, 1884 in Portugal. Based on recently collected material and older museum samples, including type specimens, we describe six new species to science, viz. Ommatoiulus alacygni sp. nov., O. camurus sp. nov., O. denticulatus sp. nov., O. litoralis sp. nov., O. staglae sp. nov. and O. stellaris sp. nov. The species O. alacygni sp. nov., O. denticulatus sp. nov. and O. staglae sp. nov. described from the Algarve are outstanding by their extremely reduced mesomerital process. The species O. porathi (Verhoeff, 1893 and O. andalusius (Attems, 1927 are recorded and redescribed for the first time after their original description. The finding of O. andalusius – originally described from Andalusia in Spain – constitutes a new record for Portugal together with two species, viz. O. fuentei (Brolemann, 1920 and O. martensi Mauriès, 1969. The taxonomic status of several species is revised. Thus Archiulus (Schistocoxitus cingulatus Attems, 1927 is here considered as a junior synonym of Ommatoiulus lusitanus (Verhoeff, 1895 while Schizophyllum cervinum Verhoeff, 1910 is synonymized with Ommatoiulus moreleti (Lucas, 1860. An identification key to all hitherto known Portuguese species of Ommatoiulus is presented as well as a distribution map illustrating the various species occurrences in the country.

  16. Climate and lake-level history of the northern Altiplano, Bolivia, as recorded in Holocene sediments of the Rio Desaguadero

    Strata exposed in terraces and modern cutbanks along the Rio Desaguadero contain a variety of lithofacies that were deposited in four distinct facies associations. These facies associations document a history of aggradation and downcutting that is linked to Holocene climate change on the Altiplano. Braided-stream, meandering-stream, deltaic and shoreline, and lacustrine sediments preserved in multi-level terraces in the northern Rio Desaguadero valley record two high-water intervals: one between 4,500 and 3,900 yr BP and another between 2,000 and 2,200 yr BP. These wet periods were interrupted by three periods of fluvial downcutting, centered at approximately 4,000 yr BP, 3,600 yr BP, and after 2,000 yr BP. Braided-river sediments preserved in a single terrace level in the southern Rio Desaguadero valley record a history of nearly continuous fluvial sedimentation from at least 7,000 yr BP until approximately 3,200 yr BP that was followed by a single episode (post-3,210 yr BP) of down-cutting and lateral migration. The deposition and subsequent fluvial downcutting of the northern strata was controlled by changes in effective moisture that can be correlated to Holocene water-level fluctuations of Lake Titicaca. The deposition and dissection of braided-stream sediments to the south are more likely controlled by a combination of base-level change and sediment input from the Rio Mauri.

  17. Father Secchi Goes to Washington

    1994-12-01

    In 1848 a small group of Jesuit refugees arrived at Georgetown College near Washington, D.C. Among them was a young priest, Angelo Secchi, who had finished theology studies in Rome, but had not been able to complete his final examinations. This done successfully, Secchi turned to astronomy and the new facilities of the Georgetown College Observatory, directed by its founder, Fr. James Curley. During his two years in Washington, Secchi studied physics, wrote an article on Electrical Rheometry for the Smithsonian Institution, and formed a friendship with Matthew Fontaine Maury of the U.S. Navy, who headed the Chart Service and in 1844 was named superintendent of the National Observatory. This was later named the U.S. Naval Observatory. Secchi's friendships formed during the Washington visit proved most helpful for relations between European astronomers and U.S. colleagues. Secchi, after his return to Rome constructed the Observatory of the Collegio Romano atop the baroque Church of St. Ignatius in Rome and began his work in spectral classification of stars.

    Full Text Available Maurie MarkmanUniversity of Texas MD Anderson Cancer Center, Houston, Texas, USAAbstract: Both pre-clinical studies and phase 1–2 clinical trials have provided strong support for the potential role of regional drug delivery in the management of epithelial ovarian cancer, a disease process whose major manifestations remain largely localized to the peritoneal cavity in the majority of individuals with this malignancy. The results of 3 phase 3 randomized trials have revealed the favorable impact of primary cisplatin-based intraperitoneal chemotherapy in women who initiate drug treatment with small-volume residual ovarian cancer following an attempt at optimal surgical cytoreduction. Concerns have been raised regarding the toxicity of regional treatment, particularly the side-effect profile associated with cisplatin. One rational approach to improving the tolerability of intraperitoneal chemotherapy is to substitute carboplatin for cisplatin. This review discusses the rationale for and data supporting regional treatment of epithelial ovarian cancer, and highlights the potential role for intraperitoneal carboplatin in this clinical setting.Keywords: ovarian cancer, intraperitoneal chemotherapy, cisplatin, carboplatin

    mechanism by which the subsequent necroinflammatory process clears the infection remain a puzzle that most likely involves the HAV-HAVCR1 interaction. Based on negative data, a recent paper from the S. M. Lemon and W. Maury laboratories (A. Das, A. Hirai-Yuki, O. Gonzalez-Lopez, B. Rhein, S. Moller-Tank, R. Brouillette, L. Hensley, I. Misumi, W.

Lemon, mBio 8:e00969-17, 2017, https://doi.org/10.1128/mBio.00969-17) suggested that HAVCR1 is not a functional HAV receptor, nor it is it required for HAV infection. However, our data, based on regain of the HAV receptor function in HAVCR1 knockout cells transfected with HAVCR1 cDNA, disagree with their findings. Our positive data show conclusively that HAVCR1 is indeed a functional HAV receptor and lays the ground for the identification of alternative HAV receptors and how they interact with HAVCR1 in cell entry and the pathogenesis of HAV.

    In 2001, Pickard and Mauri implemented the gauge including projected augmented wave (GIPAW) protocol for first-principles calculations of NMR parameters using periodic boundary conditions (chemical shift anisotropy and electric field gradient tensors). In this paper, three potentially interesting perspectives in connection with PAW/GIPAW in solid-state NMR and pure nuclear quadrupole resonance (NQR) are presented: (i) the calculation of J coupling tensors in inorganic solids; (ii) the calculation of the antisymmetric part of chemical shift tensors and (iii) the prediction of (14)N and (35)Cl pure NQR resonances including dynamics. We believe that these topics should open new insights in the combination of GIPAW, NMR/NQR crystallography, temperature effects and dynamics. Points (i), (ii) and (iii) will be illustrated by selected examples: (i) chemical shift tensors and heteronuclear (2)J(P-O-Si) coupling constants in the case of silicophosphates and calcium phosphates [Si(5)O(PO(4))(6), SiP(2)O(7) polymorphs and α-Ca(PO(3))(2)]; (ii) antisymmetric chemical shift tensors in cyclopropene derivatives, C(3)X(4) (X = H, Cl, F) and (iii) (14)N and (35)Cl NQR predictions in the case of RDX (C(3)H(6)N(6)O(6)), β-HMX (C(4)H(8)N(8)O(8)), α-NTO (C(2)H(2)N(4)O(3)) and AlOPCl(6).

  3. Feeding-Danger Trade-Offs Underlie Stopover Site Selection by Migrants

    Full Text Available To migrate successfully, birds need to store adequate fat reserves to fuel each leg of the journey. Migrants acquire their fuel reserves at stopover sites; this often entails exposure to predators. Therefore, the safety attributes of sites may be as important as the feeding opportunities. Furthermore, site choice might depend on fuel load, with lean birds more willing to accept danger to obtain good feeding. Here, we evaluate the factors underlying stopover-site usage by migrant Western Sandpipers (Calidris mauri on a landscape scale. We measured the food and danger attributes of 17 potential stopover sites in the Strait of Georgia and Puget Sound region. We used logistic regression models to test whether food, safety, or both were best able to predict usage of these sites by Western Sandpipers. Eight of the 17 sites were used by sandpipers on migration. Generally, sites that were high in food and safety were used, whereas sites that were low in food and safety were not. However, dangerous sites were used if there was ample food abundance, and sites with low food abundance were used if they were safe. The model including both food and safety best-predicted site usage by sandpipers. Furthermore, lean sandpipers used the most dangerous sites, whereas heavier birds (which do not need to risk feeding in dangerous locations used safer sites. This study demonstrates that both food and danger attributes are considered by migrant birds when selecting stopover sites, thus both these attributes should be considered to prioritize and manage stopover sites for conservation.

    The pathogenesis of Listeria monocytogenes depends on the ability of this bacterium to escape from the phagosome of the host cells via the action of the pore-forming toxin listeriolysin O (LLO). Expression of the LLO-encoding gene ( hly ) requires the transcriptional activator PrfA, and both hly and prfA genes are essential for L. monocytogenes virulence. Here, we used the hemolytic activity of LLO as a phenotypic marker to screen for spontaneous virulence-attenuating mutations in L. monocytogenes Sixty nonhemolytic isolates were identified among a collection of 57,820 confirmed L. monocytogenes strains isolated from a variety of sources (0.1%). In most cases (56/60; 93.3%), the nonhemolytic phenotype resulted from nonsense, missense, or frameshift mutations in prfA Five strains carried hly mutations leading to a single amino acid substitution (G299V) or a premature stop codon causing strong virulence attenuation in mice. In one strain, both hly and gshF (encoding a glutathione synthase required for full PrfA activity) were missing due to genomic rearrangements likely caused by a transposable element. The PrfA/LLO loss-of-function (PrfA - /LLO - ) mutants belonged to phylogenetically diverse clades of L. monocytogenes , and most were identified among nonclinical strains (57/60). Consistent with the rare occurrence of loss-of-virulence mutations, we show that prfA and hly are under purifying selection. Although occurring at a low frequency, PrfA - /LLO - mutational events in L. monocytogenes lead to niche restriction and open an evolutionary path for obligate saprophytism in this facultative intracellular pathogen.

    Shorebirds are among the most highly migratory creatures on earth. Both the study of their ecology and ongoing efforts to conserve their populations must reflect this central aspect of their biology. Many species of shorebirds use migration and staging sites scattered throughout the hemisphere to complete their annual migrations between breeding areas and nonbreeding habitats (Morrison 1984). The vast distances between habitats they use pose significant challenges for studying their migration ecology. At the same time, the large number of political boundaries shorebirds cross during their epic migrations create parallel challenges for organizations working on their management and conservation.Nebel et al. (2002) represent a collaborative effort to understand the conservation implications of Western Sandpiper (Calidris mauri) migration ecology on a scale worthy of this highly migratory species. The data sets involved in the analysis come from four U.S. states, two Canadian provinces, and a total of five nations. Only by collaborating on this historic scale were the authors able to assemble the information necessary to understand important aspects of the migration ecology of this species, and the implications for conservation of the patterns they discovered.Collaborative approaches to shorebird migration ecology developed slowly over several decades. The same period also saw the creation of large-scale efforts to monitor and conserve shorebirds. This overview first traces the history of the study of migration ecology of shorebirds during that fertile period, and then describes the monitoring and protection efforts that have been developed in an attempt to address the enormous issues of scale posed by shorebird migration ecology and conservation.

    Full Text Available Traditional knowledge from indigenous cultures about wildlife populations can offer insights beneficial for management in the face of global climate change. Semistructured interviews and workshops conducted with Maori elders from the Tuhoe tribe in the Te Urewera region of New Zealand provided knowledge about traditional management strategies for New Zealand pigeon (Hemiphaga novaeseelandiae novaeseelandiae, known locally as kereru, as well as signals of changes in local climate patterns and how these influence kereru. We used a population simulation exercise to demonstrate the feasibility of a harvest management strategy used by the Tuhoe to sustain kereru. Our models also indicated how potential changes in climate and subsequent decisions about harvest timing might affect a theoretical kereru population. Elders identified mana (authority, mauri (essence or life force, tikanga (traditional custom, and ture (societal guidelines, and the use of tohu (signals or markings, tapu (sacredness, muru (social deterrent, and rahui (temporary harvest bans as key elements and ideologies in the traditional management of kereru. They linked an increased climatic warming trend to delays of three to four months in the fruiting of some trees, such as toromiro (Podocarpus ferrugineus, deemed important for kereru nutrition and body condition. The Tuhoe have traditionally harvested both adult and newly fledged kereru when they are feeding on toromiro fruit, so a three- to four-month delay in fruiting could potentially defer the harvest until the prebreeding period. Our simulation models demonstrated that harvesting kereru adults and fledglings in the postbreeding stage had less impact on population abundance than only harvesting adults only during the prebreeding phase. The model indicated that the Tuhoe would need to re-evaluate their harvest strategy if climate-induced delays in toromiro fruiting were to become more frequent. This study emphasizes how using both

    The French Revolution brought principles of "liberty, equality, fraternity" to bear on the day-to-day challenges of governing what was then the largest country in Europe. Its experiments provided a model for future revolutions and democracies across the globe, but this first modern revolution had no model to follow. Using reconstructed transcripts of debates held in the Revolution's first parliament, we present a quantitative analysis of how this body managed innovation. We use information theory to track the creation, transmission, and destruction of word-use patterns across over 40,000 speeches and a thousand speakers. The parliament as a whole was biased toward the adoption of new patterns, but speakers' individual qualities could break these overall trends. Speakers on the left innovated at higher rates, while speakers on the right acted to preserve prior patterns. Key players such as Robespierre (on the left) and Abbé Maury (on the right) played information-processing roles emblematic of their politics. Newly created organizational functions-such as the Assembly president and committee chairs-had significant effects on debate outcomes, and a distinct transition appears midway through the parliament when committees, external to the debate process, gained new powers to "propose and dispose." Taken together, these quantitative results align with existing qualitative interpretations, but also reveal crucial information-processing dynamics that have hitherto been overlooked. Great orators had the public's attention, but deputies (mostly on the political left) who mastered the committee system gained new powers to shape revolutionary legislation.

    Full Text Available Using vessel-mounted acoustic Doppler current profiler data from four different routes between Scotland, Iceland and Greenland, we map out the mean flow of water in the top 400 m of the northeastern North Atlantic. The poleward transport east of the Reykjanes Ridge (RR decreases from ~8.5 to 10 Sv (1 Sverdrup=106 m3 s−1 at 59.5°N to 61°N to 6 Sv crossing the Iceland–Faroes–Scotland Ridge. The two longest ~1200 km transport integrals have 1.4–0.94 Sv uncertainty, respectively. The overall decrease in transport can in large measure be accounted for by a ~1.5 Sv flow across the RR into the Irminger Sea north of 59.5°N and by a ~0.5 Sv overflow of dense water along the Iceland–Faroes Ridge. A remaining 0.5 Sv flux divergence is at the edge of detectability, but if real could be accounted for through wintertime convection to >400 m and densification of upper ocean water. The topography of the Iceland Basin and the banks west of Scotland play a fundamental role in controlling flow pathways towards and past Iceland, the Faroes and Scotland. Most water flows north unimpeded through the Iceland Basin, some in the centre of the basin along the Maury Channel, and some along Hatton Bank, turning east along the northern slopes of George Bligh Bank, Lousy Bank and Bill Bailey's Bank, whereupon the flow splits with ~3 Sv turning northwest towards the Iceland–Faroes Ridge and the remainder continuing east towards and north of the Wyville-Thomson Ridge (WTR to the Scotland slope thereby increasing the Slope Current transport from ~1.5 Sv south of the WTR to 3.5 Sv in the Faroes–Shetland Channel.

    Expanding production of early-maturing soybean [Glycine max (L.) Merrill] cultivars in the southeastern USA has exposed such cultivars to a wide range of environmental conditions during seed-fill. Temperatures during this growth stage influence levels of specific fatty acids, particularly of the unsaturated fatty acids. Our objective was to evaluate the grain quality responses of early-maturing cultivars to the wide range of planting dates in the southeastern USA. Protein and oil contents along with fatty acid profiles were assessed for cultivars from Maturity Group (MG) 00 through IV using late April mid-May early June, and late June planting dates on a well-drained Maury silt loam (fine, mixed, mesic Typic Paleudalf) in 1990 through 1993. Across years and cultivars. delayed planting increased protein content and linolenic acid levels and reduced oil content and oleic acid levels but had little or no influence on palmitic stearic or linoleic acid levels. The higher seed-fill temperatures associated with early planting were strongly correlated with increased oil content and oleic acid levels and reduced linolenic acid levels. Increasing seed-fill temperatures were closely associated with reduced linolenic acid levels for all six cultivars. However, the oleic acid response to seed-temperatures strongly depended on cultivar maturity. Oleic acid levels of early-maturing cultivars were much more sensitive to seed-fill temperatures than were those of later maturing cultivars. While other effects of environment on grain quality characteristics may be relatively small perhaps the quality of new low linolenic acid cultivars could be amplified through culture under the warmer conditions the southeastern USA

The major milestone in the commissioning of the synchrotron was on October 11, 1967 when Helen Edwards, Boyce McDaniel, and Maury Tigner achieved a 7 GeV beam, a worldrecord energy for electron synchrotrons at that time. Like so many advances in experimental physics, this occurred early in the morning - 3 a.m.! The transition from accelerator commissioning to high energy physics operation was extremely rapid; 7 GeV operation for data collection was routine just five weeks later. Throughout its life as a source of photon and electron beams for fixed target experiments, the synchrotron maintained energy leadership for circular electron machines. Originally designed for operation at 10 GeV, eventually it consistently provided beams for experiments at energies up to 11.6 GeV. It now operates at 5 GeV, serving as the injector for the CESR electron-positron storage ring. Robert Wilson was director of the laboratory during the design and most of the construction of the machine. He left near the end of the construction to become the first director of Fermilab and was replaced by Boyce McDaniel, who guided the laboratory from the completion of the synchrotron to the construction and early operation of CESR. Wilson recalled how the laboratory had originally proposed a 3 GeV turnkey machine to be built entirely by industry and would fit in the space previously occupied by earlier Cornell accelerators. However, members of the laboratory realized that 3 GeV would not open new physics frontiers, that the construction of the accelerator was much of the fun of doing high energy physics experiments, and that a more challenging project was needed.

    The development of knowledge of global biogeography of the oceans from sixteenthcentury European voyages of exploration to present-day use of satellite remote sensing is reviewed in three parts; the pre-satellite era (1513-1977), the satellite era leading to a first global synthesis (1978-1998), and more recent studies since 1998. The Gulf Stream was first identified as a strong open-ocean feature in 1513 and by the eighteenth century, regular transatlantic voyages by sailing ships had established the general patterns of winds and circulation, enabling optimisation of passage times. Differences in water temperature, water colour and species of animals were recognised as important cues for navigation. Systematic collection of information from ships' logs enabled Maury (The Physical Geography of the Sea Harper and Bros. New York 1855) to produce a chart of prevailing winds across the entire world's oceans, and by the early twentieth century the global surface ocean circulation that defines the major biogeographic regions was well-known. This information was further supplemented by data from large-scale plankton surveys. The launch of the Coastal Zone Color Scanner, specifically designed to study living marine resources on board the Nimbus 7 polar orbiting satellite in 1978, marked the advent of the satellite era. Over subsequent decades, correlation of satellite-derived sea surface temperature and chlorophyll data with in situ measurements enabled Longhurst (Ecological Geography of the Sea. Academic Press, New York 1998) to divide the global ocean into 51 ecological provinces with Polar, Westerly Wind, Trade Wind and Coastal Biomes clearly recognisable from earlier subdivisions of the oceans. Satellite imagery with semi-synoptic images of large areas of the oceans greatly aided definition of boundaries between provinces. However, ocean boundaries are dynamic, varying from season to season and year to year. More recent work has focused on the study of variability of

  17. Characteristics of broadband slow earthquakes explained by a Brownian model

    Ide, S.; Takeo, A.

    2017-12-01

    Brownian slow earthquake (BSE) model (Ide, 2008; 2010) is a stochastic model for the temporal change of seismic moment release by slow earthquakes, which can be considered as a broadband phenomena including tectonic tremors, low frequency earthquakes, and very low frequency (VLF) earthquakes in the seismological frequency range, and slow slip events in geodetic range. Although the concept of broadband slow earthquake may not have been widely accepted, most of recent observations are consistent with this concept. Then, we review the characteristics of slow earthquakes and how they are explained by BSE model. In BSE model, the characteristic size of slow earthquake source is represented by a random variable, changed by a Gaussian fluctuation added at every time step. The model also includes a time constant, which divides the model behavior into short- and long-time regimes. In nature, the time constant corresponds to the spatial limit of tremor/SSE zone. In the long-time regime, the seismic moment rate is constant, which explains the moment-duration scaling law (Ide et al., 2007). For a shorter duration, the moment rate increases with size, as often observed for VLF earthquakes (Ide et al., 2008). The ratio between seismic energy and seismic moment is constant, as shown in Japan, Cascadia, and Mexico (Maury et al., 2017). The moment rate spectrum has a section of -1 slope, limited by two frequencies corresponding to the above time constant and the time increment of the stochastic process. Such broadband spectra have been observed for slow earthquakes near the trench axis (Kaneko et al., 2017). This spectrum also explains why we can obtain VLF signals by stacking broadband seismograms relative to tremor occurrence (e.g., Takeo et al., 2010; Ide and Yabe, 2014). The fluctuation in BSE model can be non-Gaussian, as far as the variance is finite, as supported by the central limit theorem. Recent observations suggest that tremors and LFEs are spatially characteristic

    Wild birds have been implicated in the spread of highly pathogenic avian influenza (HPAI) of the H5N1 subtype, prompting surveillance along migratory flyways. Sampling of wild birds for avian influenza virus (AIV) is often conducted in remote regions, but results are often delayed because of the need to transport samples to a laboratory equipped for molecular testing. Real-time reverse transcriptase polymerase chain reaction (rRT-PCR) is a molecular technique that offers one of the most accurate and sensitive methods for diagnosis of AIV. The previously strict lab protocols needed for rRT-PCR are now being adapted for the field. Development of freeze-dried (lyophilized) reagents that do not require cold chain, with sensitivity at the level of wet reagents has brought on-site remote testing to a practical goal. Here we present a method for the rapid diagnosis of AIV in wild birds using an rRT-PCR unit (Ruggedized Advanced Pathogen Identification Device or RAPID, Idaho Technologies, Salt Lake City, UT) that employs lyophilized reagents (Influenza A Target 1 Taqman; ASAY-ASY-0109, Idaho Technologies). The reagents contain all of the necessary components for testing at appropriate concentrations in a single tube: primers, probes, enzymes, buffers and internal positive controls, eliminating errors associated with improper storage or handling of wet reagents. The portable unit performs a screen for Influenza A by targeting the matrix gene and yields results in 2-3 hours. Genetic subtyping is also possible with H5 and H7 primer sets that target the hemagglutinin gene. The system is suitable for use on cloacal and oropharyngeal samples collected from wild birds, as demonstrated here on the migratory shorebird species, the western sandpiper (Calidrus mauri) captured in Northern California.

This situation has heightened the need for novel antimicrobial therapies as alternatives to traditional antibiotics. The combination of metallic nanoparticles and laser exposure has been proposed as a strategy to induce physical damage to bacteria, regardless of antibiotic sensitivity. The purpose of this study was to test the antibacterial effect of antibody-targeted gold nanoparticles combined with pulsed laser irradiation.Methods: Gold nanoparticles conjugated to antibodies specific to Staphylococcus aureus peptidoglycan were incubated with suspensions of methicillin-resistant and methicillin-sensitive S. aureus (MRSA and MSSA. Bacterial suspensions were then exposed to 8 ns pulsed laser irradiation at a wavelength of 532 nm and fluences ranging from 1 to 5 J/cm2. Viability of the bacteria following laser exposure was determined using colony forming unit assays. Scanning electron microscopy was used to confirm the binding of nanoparticles to bacteria and the presence of cellular damage.Results: The laser-activated nanoparticle treatment reduced the surviving population to 31% of control in the MSSA population, while the survival in the MRSA population was reduced to 58% of control. Significant decreases in bacterial viability occurred when the laser fluence exceeded 1 J/cm2, and this effect was linear from 0 to 5 J/cm2 (r2=0.97. Significantly less bactericidal effect was observed for nonfunctionalized nanoparticles or

    New Zealand is a multicultural society, founded on the Treaty of Waitangi which when enshrined into various legislation and national policy, provides incentive to incorporate indigenous Māori world views into nationally funded science and research programmes. Here we discuss how the integration of indigenous world views and western science were combined in a research proposal that resulted in successful funding for a 5 year collaborative science programme. The programme strives to develop an expanded national soil health framework for New Zealand that will be used by policy makers, local government, indigenous Māori, industry, and primary sector groups to maintain the natural capital and productivity of soils within environmental constraints. Soil health is fundamental to economic, social, and human wellbeing, and provides a myriad of ecosystem and environmental services, such as those sustaining food and fibre production. Typically soil health is defined by "dynamic" soil characteristics that are susceptible to changes in land use or land management over relatively short time frames (years to decades). Soil resilience, however, is a much longer-term concept that is not well captured in current soil health thinking. The Māori world view encapsulates such long term thinking through interconnected Māori values and inter-generational concepts (e.g., whakapapa, rangatiratanga, manawhenua, kaitiakitanga, mauri) that provide the basis for indigenous resource management in Aotearoa-New Zealand. These values and recognition of the Treaty of Waitangi provide authority and rights to manage resources according to tikanga (customs, principles). Māori environmental concepts and knowledge combined with science concepts for understanding soil health and resilience, served as a powerful central theme for the design and implementation of this science program. Māori involvement and capability development are integral to this research effort and we believe the synthesis of M

    Full Text Available En représentant les démons dans la Tentation de saint Antoine, Flaubert transforme un concept chrétien par un concept psychologique élaboré par Alfred Maury, à savoir celui de l’hallucination hypnagogique. Mais ce n’est qu’à travers les différentes variantes du texte qu’on peut observer ce processus de substitution. Dans la première version de 1849, les apparitions sont toujours appelées des « démons ». Quand on lit Die christliche Mystik de Joseph von Görres que Flaubert a connu par la traduction de Charles Sainte-Foi (La mystique divine, naturelle et diabolique, Paris, 1862 on peut faire une découverte intéressante : Görres opère une distinction entre une « vraie » mystique chrétienne et une « fausse » mystique démoniaque. Ce qui là s’appelle l’extase est ici la possession par les démons. Toute la démonologie est expliquée par une conception hérétique du Mal, laquelle repose sur une fausse substantialisation, et dont il voit la manifestation la plus pure dans la religion gnostique du manichéisme. Or, comme l’on sait, Antoine est fortement attiré par la Gnose qui est, au sens grec du terme, une religion de la connaissance. Avec les adhérents de la Gnose il partage le dualisme entre un monde matériel, terrestre et un principe premier d’essence divine dans l’au-delà. Ainsi faut-il se poser la question s’il réussit finalement à surmonter le dualisme en recevant la connaissance ou bien si les dualismes continuent à persister dans le texte. La lecture de la Tentation mène à un double résultat : D’un point de vue macro-structurel, l’élément gnostique reste le non-surmontement du dualisme, lequel s’exprime sur le plan rhétorique par la résistance de l’allégorique dans le texte. En revanche, à la fin du texte, le dualisme est surmonté une seule fois dans la mise en scène d’une inversion du monisme (être-dans-le-monde et du dualisme (acosmisme.Representing the demons

    Declines in avian populations are a global concern, particularly for species that migrate between Arctic-temperate and tropical locations. Long-term population studies offer opportunities to detect and document ecological effects attributable to long-term climatic cycles such as the El Niño/Southern Oscillation (ENSO). In this study, we report possible population-level effects of such climatic cycles on shorebird species that use two non-breeding season sites in Ecuador (Santa Elena peninsula area, near La Libertad). During our 9-year study period (1991/1992-1999/2000), there was a particularly strong ENSO warm phase event during 1997/1998. Population trend data for three species of shorebird, Western Sandpipers ( Calidris mauri), Semipalmated Sandpipers ( C. pusilla), and Least Sandpipers ( C. minutilla), indicated abundances generally declined during the 1990s, but there was an increase in the proportion of first-year birds and their abundance in the years following the 1997/1998 ENSO warm phase. There was some support for variation in apparent survivorship associated with the onset of the ENSO warm phase event in our population models, based on capture-mark-recapture data. Following the 1997/1998 ENSO event onset, individuals for all three species were significantly lighter during the non-breeding season ( F1,3789 = 6.6, p = 0.01). Least-squares mean mass (controlling for size, sex and day of capture) for first-year birds dropped significantly more than for adults following ENSO (first-year mass loss = 0.69 ± 0.12 g; adult mass loss = 0.34 ± 0.11 g, F1,3789 = 5.31, p = 0.021), and least-squares mean mass dropped most during the period when sandpipers prepare for northward migration by gaining mass and moulting into breeding plumage. Least Sandpipers may have declined the most in mean mass following ENSO (0.76 ± 0.19 g), whereas Semipalmated Sandpipers were 0.52 ± 0.12 g lighter, and Western Sandpipers 0.40 ± 0.13 g lighter, but overall variation among

  4. Introduction of a Uranium tax in Finland

    International Nuclear Information System (INIS)

    In Finland, it is possible to create a tax model on uranium that will not compromise the profitability of future power plant investments or decisively reduce climate policy incentives for carbon-free energy production. The rise in energy costs caused by the tax could be compensated by lowering the electricity tax imposed on industry. The estimates above were made by Managing Director Pasi Holm and Professor Markku Ollikainen, who, on 4 February 2011, handed over their report concerning introduction of uranium tax to Minister of Economic Affairs Mauri Pekkarinen. According to the administrators, one can deem nuclear power to include specific grounds for imposing a tax via the fact that storage of used nuclear fuel involves a (infinitesimally small) risk of accidents with irreversible effects, and that, through the EU climate policy, nuclear power companies gain extra profit 'for nothing', i.e. windfall profit. The EU Energy Tax Directive facilitates collection of uranium tax. Uranium tax, imposed as an excise tax, would target the nuclear power plants in operation as well as the Olkiluoto 3 plant, presently under construction. The amount of uranium fuel used would serve as the basis of taxation. Holm and Ollikainen introduce two tax models, adjustable in a manner that the uranium tax would yield revenues of approximately EUR 100 million a year. The companies would still keep more than half of the profit and the state, depending on the model used, would collect 43 to 45 per cent of it via the tax. In the minimum tax model, the uranium tax is 44.5 of the difference between the market price of emission allowance and the average price of 2010 (EUR 15/tonne of CO 2 ), used as the comparison price, the minimum being EUR 2/MWh. The tax would yield a minimum of EUR 67 million to the state a year. When the emission allowance price rises to EUR 30, the tax would be EUR 6.7/MWh and the state would earn revenues of EUR 223 million. In a flexible tax model, the fixed part of the

La prima parte dell’articolo è dedicata alla definizione del linguaggio del turismo e, in particolare, alle caratteristiche dal discorso orale delle guide turistiche, esito della mediazione tra linguaggio di specialità e lingua comune. Nella seconda parte viene introdotta e sviluppata l’analisi linguaggio orale delle guide turistiche a partire da un corpus costituito da diciotto file di trascrizione di registrazioni di visite guidate, in lingua italiana, svolte da guide turistiche straniere all’estero. Dallo studio effettuato è emerso come le scelte linguistiche dell’operatore professionale si declinino in funzione delle esigenze e delle caratteristiche del destinatario: ad un turista desideroso di «vedere», «conoscere» e «identificare» nello spazio ciò di cui si parla, la guida turistica risponde con un ampio impiego del verbo «chiamarsi» e di componenti grammaticali e lessicali (verbi, avverbi e preposizioni di luogo, aggettivi dimostrativi con un forte valore locativo.   Tourist guide italian: a study of the oral language of tourism   Elena Mauri    The object of this article is the oral language of tourist guides, a “special”, hard to find and poorly analyzed type of language production.

    Middle Proterozoic rocks underlying the Andes in western Bolivia, western Argentina, and northern Chile and Early Proterozoic rocks of the Arequipa massif in southern Peru?? from the Arequipa-Antofalla craton. These rocks are discontinuously exposed beneath Mesozoic and Cenozoic rocks, but abundant crystalline clasts in Tertiary sedimentary rocks in the western altiplano allow indirect samples of the craton. Near Berenguela, western Bolivia, the Oligocene and Miocene Mauri Formation contains boulders of granodiorite augen gneiss (1171??20 Ma and 1158??12 Ma; U-Pb zircon), quartzose gneiss and granofels that are inferred to have arkosic protoliths (1100 Ma source region; U-Pb zircon), quartzofeldspathic and mafic orthogneisses that have amphibolite- and granulite-facies metamorphic mineral assemblages (???1080 Ma metamorphism; U-Pb zircon), and undeformed granitic rocks of Phanerozoic(?) age. The Middle Proterozoic crystalline rocks from Berenguela and elsewhere in western Bolivia and from the Middle Proterozoic Bele??n Schist in northern Chile generally have present-day low 206Pb/204Pb ( 15.57), and elevated 208Pb/204Pb (37.2 to 50.7) indicative of high time-averaged Th/U values. The Middle Proterozoic rocks in general have higher presentday 206Pb/204Pb values than those of the Early Proterozoic rocks of the Arequipa massif (206Pb/204Pb between 16.1 and 17.1) but lower than rocks of the southern Arequipa-Antofalla craton (206Pb/204Pb> 18.5), a difference inferred to reflect Grenvillian granulite metamorphism. The Pb isotopic compositions for the various Proterozoic rocks lie on common Pb isotopic growth curves, implying that Pb incorporated in rocks composing the Arequipa-Antofalla craton was extracted from a similar evolving Pb isotopic reservoir. Evidently, the craton has been a coherent terrane since the Middle Proterozoic. Moreover, the Pb isotopic compositions for the Arequipa-Antofalla craton overlap those of the Amazon craton, thereby supporting a link

    equal density in the stratified water column, presumably the pycnocline, where they spread out laterally, even up-current, and generate interflows that deposit graded layers. The process is slow enough to allow incorporation into the graded layers of debris melting out of drifting icebergs. The hyperpycnal portion of individual discharge events that generated these currents might have had an estimated volume on the order of 103 km3x(1012 m3) which would have flowed for 10-15 days or less, assuming estimated discharge ranges for subglacial outburst floods of up to 106 m3/s. Turbidites are deposited much too fast to incorporate any substantial fraction of IRD, whereas deposition from lofted interflows may take months. The most likely candidates for the parent currents from which lofting occurred were the sandy flows that formed the sand abyssal plain The observed lofted depositional facies is exclusively found in Heinrich layers at distances of up to 300 km from the presumed terminus of the Hudson Strait ice stream. Through this stratigraphic relationship the lofted facies ties the main pulses of Late Pleistocene sediment supply in the Labrador Basin to Heinrich events. Heinrich events are known as Late Pleistocene ice-rafting episodes of unparalleled intensity in the North Atlantic that were associated with major melt-water discharge pulses and, as it appears now, also were the times of the main sediment delivery. Other potential basin candidates where lofting may have occurred are the Bering Sea and Maury Channel in North Atlantic.

    generated from fresh-water discharges into the sea that can produce reversed buoyancy, as is well known from experiments. When the flows have traveled long enough, their tops will have lost enough sediment by settling such that their density decreases below that of the ambient seawater causing the current tops to lift up. The turbid fresh-water clouds buoyantly rise out of the turbidity current to a level of equal density, presumably the pycnocline, where they spread out laterally, even up-current, and generate interflows that deposit graded layers. The process is slow enough to allow incorporation into the graded layers of debris melting out of drifting icebergs. The observed lofted depositional facies is exclusively found in Heinrich layers. The most likely candidates for the parent currents from which lofting occurred were the sandy flows that formed the sand abyssal plain. Through this stratigraphic relationship the lofted facies ties the main pulses of Late Pleistocene sediment supply in the Labrador Basin to Heinrich events. Dating of pelagic interlayers during future ocean drilling may provide the proof that packages of sand turbidites underlying the abyssal plain are correlated to individual Heinrich events. The correlation may thus be documented in the stratigraphic record. Similar situations may exist in the Bering Sea or along the Maury Channel System in North Atlantic.

The aim of this study was to assess the subjective well-being in patients with schizophrenia and to examine its relationship with the presence and severity of depressive symptoms.Methods: A multicenter, cross-sectional study was conducted with clinically stable outpatients diagnosed with schizophrenia. The Subjective Well-Being under Neuroleptic Scale – short version (SWN-K and the Calgary Depression Scale for Schizophrenia (CDSS were used to gather information on well-being and the presence and severity of depressive symptoms, respectively. Spearman’s rank correlation was used to assess the associations between the SWN-K total score, its five subscales, and the CDSS total score. Discriminative validity was evaluated against that criterion by analysing the area under the curve (AUC.Results: Ninety-seven patients were included in the study. Mean age was 35 years (standard deviation = 10 and 72% were male. Both the total SWN-K scale and its five subscales correlated inversely and significantly with the CDSS total score (P < 0.0001.

The outburst occurred right on schedule, peaking on 5 December 2015, and the results of the observing campaign are now presented in a study led by Mauri Valtonen (University of Turku).Optical photometry of OJ 287 from October to December 2015, showing the outburst that resulted from the secondary black hole crossing the disk. [Valtonen et al. 2016]Because the secondary black holes orbit is affected by the spin of the primary black hole, Valtonen and collaborators were able to use the timing of the outburst to measure the spin of OJ 287s primary black hole to remarkably high precision. They find that its Kerr parameter is 0.313 0.01 which means its spinning at about a third of the maximum rate allowed by general relativity.The outburst timing also confirmed several general-relativistic properties of the system, including its loss of energy to gravitational waves. Remarkably, the energy lost as the secondary black hole punches through the accretion disk is still ten thousand times smaller than the amount of energy it loses through gravitational waves!The observations from this outburst have provided important black-hole measurements and tests of general relativity which are especially relevant in this new era of gravitational wave detections. And we may be able to perform still more tests on the secondarys next pass through the disk, which should occur in 2019.BonusCheck out this awesome animation of the orbits in a system similar to OJ 287! The secondarys orbit precesses around the primary due to general-relativistic effects. The sound you hearis an audio representation of the increasing frequency as the two black holes inspiral.

    /Y). Contrarily, when a young (subducted, the geothermal gradient along the Benioff plane is high, so the temperature of hydrated tholeiite solidus is reached before dehydration occurs. Under these conditions, garnet and/or hornblende are the main residual phases giving rise to HREE-depleted magmas (high La/Yb). The lack of residual plagioclase accounts for the Sr enrichment (high Sr/Y) of the magma. Experimental petrologic data show that the liquids produced by melting of tholeiite in subduction-like P- T conditions are adakitic in composition. However, natural adakites systematically have higher Mg no., Ni and Cr contents, which are interpreted as reflecting interactions between the ascending adakitic magma generated in the subducted slab and the overlying mantle wedge. This interpretation has been recently corroborated by studies on ultramafic enclaves in Batan lavas where olivine crystals contain glass inclusions with adakitic compositions [Schiano, P., Clochiatti, R., Shimizu, N., Maury, R., Jochum, K.P., Hofmann, A.W., 1995. Hydrous, silica-rich melts in the sub-arc mantle and their relationships with erupted arc lavas. Nature 377 595-600.]. This is interpreted as demonstrating that adakitic magmas passed through the mantle wedge and interacted with it. Sajona [Sajona, F.G., 1995. Fusion de la croûte océanique en contexte de subduction collision: géochimie, géochronologie et pétrologie du magmatisme plioquaternaire de Mindanao (Philippines). Unpublished thesis, Brest University, France, 223 pp.] also considers that the high-Nb basalts, which are associated with adakites, reflect mantle-adakite interactions. Recent structural studies have demonstrated that plate tectonics operated during the first half of Earth history. The very strong similarities that exist between modern adakites and Archaean tonalite, trondhjemite and granodiorite (TTG) attest that both have the same source and petrogenesis. Consequently, when Archaean-like P- T conditions are exceptionally realised

    . This is more than a factor one hundred smaller than Pluto's surface pressure, which is estimated to be in the range 10-15 microbars. "Comparing Pluto and Charon, we seem to cross a borderline between bodies which may have bound atmospheres - like Pluto - and airless bodies like Charon", said Olivier Hainaut, from ESO and member of the team. The observations also indicate that methane ice, if present, should be restricted to very cold regions of the surface. Similarly, nitrogen ice would be confined at best to high northern latitudes or permanently shadowed regions of Charon. As Pluto and its satellite sweep across the Milky Way, observations of more occultations will be tempted from the ground, while the NASA's Pluto-Kuiper Belt Mission, to be launched in January 2006, will be travelling towards the planet, that it should reach in July 2015.

    next year as a research assistant (later research associate) at Harvard College Observatory, then directed by Harlow Shapley, about whom her opinion was much warmer than that expressed by Cecilia Payne Gaposchkin. Dorrit's immediate supervisor at Harvard was Henrietta Swope, daughter of the President of General Electric, and eventually best known for work at Mount Wilson Observatory with Walter Baade on variable stars in the Magellanic Clouds, published in papers that continued to appear long after Baade's death. Hoffleit's first ten papers were also on variable stars and appeared in Harvard Observatory publications. But the MA she completed in 1932 was on the light curves of meteors and was published in the Proceedings of the United States National Academy of Sciences. By this time, Dorrit had established a work pattern that was to persist right up to retirement - at least 40 hours per week on whatever the current boss thought she should be doing, and another 20 or so on other astronomical research that interested her. Hffleit had supposed that an MA would be her highest degree, but Shapley urged her to go on for a PhD, with, it would seem, a bit of urging on both sides from Bart Bok, who informed her that "if God recommends that you do something, it is your duty to do it." The thesis (PhD 1938) was on yet a third topic, spectroscopic parallaxes. This means determining the luminosities of stars, hence their distances, from line width and ratio diagnostics in their spectra. The pioneer was Antonia Maury, whose insights were not appreciated by Shapley's predecessor, E. C. Pickering. Another valuable Hoffleit mentor was Ernst Öpik, on a three-month visit to Harvard in 1934, from whom Dorrit learned stellar statistics and half a dozen other things. The thesis also provided her "break out" paper into the Astrophysical Journal (on CN as a giant/dwarf discriminator). Hoffleit began to branch out into astrometry, comets, and other parts of astronomy and, starting in 1941

    realized that water is a poor conductor of heat and, unlike that of freshwater, the density of seawater continues to increase as it is cooled to its freezing point; the far-reaching significance of the implied vertical convection and deep circulation of the ocean on the moderation of climate was immediately clear (Rumford), though observations were available almost exclusively from the ocean's surface. Largely because of the marine chronometer, a wealth of unprecedentedly-accurate information about zonal, as well as meridional, surface currents began to accumulate in various hydrographic offices. In the early nineteenth century data from the Atlantic were collected and reduced in a systematic fashion (Rennell), to produce the first detailed description of the major circulation patterns at the surface for the entire mid- and low-latitude Atlantic, along with evidence for cross-equatorial flow. This work provided a foundation for the assemblage of a global data set (Humboldt; Berghaus) that yielded a worldwide charting of the non-polar currents by the late 1830s. Subtleties such as the North Equatorial Countercurrent in the Pacific were revealed for the first time. During the next two decades, the western intensification of subtropical gyres was recognized (Wilkes) while numerous refinements were made to other global descriptions (Wilkes; Kerhallet; Findlay). Heuristic and often incorrect theories of what causes the circulations in the atmosphere and oceans were popularized in the 1850s and 1860s which led to a precipitous decline in the quality of charts intended for the public (Maury; Gareis and Becker). Such errors in popular theories provided motivation for the adoption of analytical methods, which in turn led directly to the discovery of the full effect of Earth's rotation on relatively large-scale motion and the realization of how that effect produces flow perpendicular to horizontal pressure gradients (Ferrel). The precedents for modern dedicated research cruises came
