    Richard von Volkmann (1830–1889), one of the most important surgeons of the 19th century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867–1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the “antiseptic technique” to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann’s contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children’s fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

    Full Text Available Alpine research benefits from several international coordination networks, only one of which – ISCAR (the International Scientific Committee on Research in the Alps – works solely in the Alpine arc. The creation of ISCAR is a consequence of the input and involvement of various Alpine partners around the Alpine Convention. Alpine research now aims to promote an integrated vision of Alpine territories focusing on creating and maintaining spatial and temporal networks of sustainable relationships between humans and the other components of the ecosphere. It combines resource usage with conservation of the biological and cultural diversity that makes up the Alpine identity. This article aims to show: (1 how international Alpine research coordination is organised; (2 the role played by the Alpine Convention as a framework of reference for specifically Alpine research; and (3 the role that the ISCAR international commit-tee and the Interreg “Alpine Space” programmes play in uniting research around territorial challenges relating to biodiversity conservation and territorial development.La recherche sur les Alpes bénéficie de plusieurs réseaux de coordination internationaux dont un seul, le comité international recherche alpine (ISCAR, se consacre exclusivement à l’arc alpin.

  20. Richard's back: death, scoliosis and myth making.

    Science.gov (United States)

    Lund, Mary Ann

    2015-12-01

    The body of a mediaeval monarch was always under scrutiny, and Richard III's was no exception. In death, however, his body became subject to new forms of examination and interpretation: stripped naked after the battle of Bosworth, his corpse was carried to Leicester and exhibited before being buried. In 2012, it was rediscovered. The revelation that Richard suffered from scoliosis prompts this article to re-evaluate the historical sources about Richard's physique and his posthumous reputation. This article argues that Richard's death and his myth as 'crookback' are inextricably linked and traces attitudes to spinal curvature in the early modern period. It also considers how Shakespeare represented Richard as deformed, and aspects of performance history which suggest physical vulnerability. It then considers Richard's scoliosis from the perspective of medical history, reviewing classical accounts of scoliosis and arguing that Richard was probably treated with a mixture of axial traction and pressure. It demonstrates from the evidence of Richard's medical household that he was well placed to receive hands-on therapies and considers in particular the role of his physician and surgeon, William Hobbes. Finally, it shows how the case of Richard III demonstrates the close relationship between politics and medicine in the period and the contorted process of historical myth making.

  5. Richards Barrier LA Reference Design Feature Evaluation

    1999-01-01

    The Richards Barrier is one of the design features of the repository to be considered for the License Application (LA), Richards was a soil scientist who first described the diversion of moisture between two materials with different hydrologic properties. In this report, a Richards Barrier is a special type of backfill with a fine-grained material (such as sand) overlaying a coarse-grained material (such as gravel). Water that enters an emplacement drift will first encounter the fine-grained material and be transported around the coarse-grained material covering the waste package, thus protecting the waste package from contact with most of the groundwater. The objective of this report is to discuss the benefits and liabilities to the repository by the inclusion of a Richards Barrier type backfill in emplacement drifts. The Richards Barrier can act as a barrier to water flow, can reduce the waste package material dissolution rate, limit mobilization of the radionuclides, and can provide structural protection for the waste package. The scope of this report is to: (1) Analyze the behavior of barrier materials following the intrusion of groundwater for influxes of 1 to 300 mm per year. The report will demonstrate diversion of groundwater intrusions into the barrier over an extended time period when seismic activity and consolidation may cause the potential for liquefaction and settlement of the Richards Barrier. (2) Review the thermal effects of the Richards Barrier on material behavior. (3) Analyze the effect of rockfall on the performance of the Richards Barrier and the depth of the barrier required to protect waste packages under the barrier. (4) Review radiological and heating conditions on placement of multiple layers of the barrier. Subsurface Nuclear Safety personnel will perform calculations to determine the radiation reduction-time relationship and shielding capacity of the barrier. (5) Evaluate the effects of ventilation on cooling of emplacement drifts and

    To investigate the relevant prognostic factors and their differences between colorectal cancer (CRC) patients of Chinese Han and Hui ethnicities in the Beijing region. A retrospective analysis of 880 patients diagnosed with CRC at Xuanwu Hospital, Capital Medical University between September 2001 and September 2011 was performed. Among the 880 patients, 398 and 482 were Hui and Han, respectively. Characteristics including sex, age, diet, tumor size, primary tumor site, Dukes' stage and degree of differentiation were analyzed for their influence on prognosis. Data on dietary structures were recorded through a questionnaire survey conducted during the patient's first visit, return visit or follow-up checkups. Among patients with colon cancer, the 5-year survival rate for patients of Hui ethnicity was lower than that for Han patients (P = 0.025). Six risk factors (age of onset, dietary structure, tumor size, Dukes' stage, location of cancer and degree of differentiation) in both Han and Hui patients were identified as prognostic factors (P dietary structure was a statistically significant factor, and diet varied significantly between the two ethnic groups. Dietary structure has a significant influence on colon cancer prognosis among Han and Hui patients with colon cancer in Beijing, which may cause a difference in their survival rates.

    Science.gov (United States)

    Jannuzi, Buell Tomasson; Bechtold, Jill

    2004-12-01

    Richard Joseph Elston, known for his development of innovative astronomical instrumentation, died on 26 January 2004 in Gainesville, Florida, after a four-year battle with Hodgkin's lymphoma. A professor of astronomy at the University of Florida, Richard had an unusually broad range of interests and skills, and a willingness to share his passion for astronomy with others, which made him a highly valued member of the astronomical community. Born 1 July 1960, in Albuquerque, New Mexico, Richard was the son of a geologist father and journalist mother. His childhood interest in astronomy and instrumentation matured as he majored in physics and astronomy at the University of New Mexico (BS, 1983) under the mentorship of Michael Zeilik. Richard pursued his PhD in astronomy at the University of Arizona and earned his degree in 1988. He pioneered the use of IR arrays for deep imaging surveys of the sky to study galaxy formation, and completed his thesis Search for Rapidly Forming Galaxies at High Redshift under the direction of George Rieke. Richard's graduate work included the first detection of galaxies at intermediate redshifts with evolved populations too red to have been identifiable from optical imaging surveys alone. In the Astrophysical Journal Letters in 1988, he, George Rieke, and Marcia Rieke reported the discovery of this new class of galaxies, now known as EROs (Extremely Red Objects), important as the possible progenitors of present day elliptical galaxies. Following post-doctoral positions at Kitt Peak National Observatory from 1988 to 1991 and at the Observatories of the Carnegie Institution of Washington from 1991 to 1992, Richard joined the scientific staff of Cerro Tololo Inter-American Observatory in Chile, part of the NSF's National Optical Astronomy Observatory. By 1994, he had become head of CTIO's IR instrumentation program and was leading the development of new instruments for the US astronomical community. In 1996, Richard married astronomer

  14. Comparison of Genetic Variants in Cancer-Related Genes between Chinese Hui and Han Populations.

    Directory of Open Access Journals (Sweden)

    Chaoyong Tian

    Full Text Available The Chinese Hui population, as the second largest minority ethnic group in China, may have a different genetic background from Han people because of its unique demographic history. In this study, we aimed to identify genetic differences between Han and Hui Chinese from the Ningxia region of China by comparing eighteen single nucleotide polymorphisms in cancer-related genes.DNA samples were collected from 99 Hui and 145 Han people from the Ningxia Hui Autonomous Region in China, and SNPs were detected using an improved multiplex ligase detection reaction method. Genotyping data from six 1000 Genomes Project population samples (99 Utah residents with northern and western European ancestry (CEU, 107 Toscani in Italy (TSI, 108 Yoruba in Ibadan (YRI, 61 of African ancestry in the southwestern US (ASW, 103 Han Chinese in Beijing (CHB, and 104 Japanese in Tokyo (JPT were also included in this study. Differences in the distribution of alleles among the populations were assessed using χ2 tests, and FST was used to measure the degree of population differentiation.We found that the genetic diversity of many SNPs in cancer-related genes in the Hui Chinese in Ningxia was different from that in the Han Chinese in Ningxia. For example, the allele frequencies of four SNPs (rs13361707, rs2274223, rs465498, and rs753955 showed different genetic distributions (p0.000 between the Hui and Han populations.These results suggest that some SNPs associated with cancer-related genes vary among different Chinese ethnic groups. We suggest that population differences should be carefully considered in evaluating cancer risk and prognosis as well as the efficacy of cancer therapy.

    Energy Technology Data Exchange (ETDEWEB)

    Kelley, C.T.; Miller, C.T.; Tocci, M.D.

    1996-12-31

    We consider the method of lines solution of Richard`s equation, which models flow through porous media, as an example of a situation in which the method can give incorrect results because of premature termination of the nonlinear corrector iteration. This premature termination arises when the solution has a sharp moving front and the Jacobian is ill-conditioned. While this problem can be solved by tightening the tolerances provided to the ODE or DAE solver used for the temporal integration, it is more efficient to modify the termination criteria of the nonlinear solver and/or recompute the Jacobian more frequently. In this paper we continue previous work on this topic by analyzing the modifications in more detail and giving a strategy on how the modifications can be turned on and off in response to changes in the character of the solution.

There were 1 053 plant medicines which belong to 169 family and 694 genus. These plant medicines mainly distributed in the southern, west southern and east southern area of Yunnan province, the southern area of Guangxi, Guangdong, Guizhou, Sichuan, Fujian province and tropical, subtropical district as Taiwan, and more than 94.49% plant medicines could be found in Yunnan province. From the point of plant life form, they were major herbaceous or shrubby plants; When it is used as medicinal part, root and rhizome of plants account for the highest proportion, the next were whole plant and leaves. From nature, flavor and channel tropism points of view, the largest proportion of Dai medicines were cool, bitter-tasted and possesses water element. In terms of treatment of disease types, most of the drugs can treat gastrointestinal diseases, next were drugs that could be used to treat upper respiratory infection, traumatological and rheumatic diseases, urinary infection, gynecological diseases, hepatopathy, puerperium fever and diseases caused by poisonous insects and beast of prey bite. The study revealed that the resources of traditional Dai medicine and traditional knowledge of application were abundant in China, but the resources of traditional Dai medicine and traditional knowledge of application were faced with the risk of gradually reduce and loss. The article suggested that we should

    Temperature and humidity are the main factors affecting the drying of Hui ink. For the experiment, fresh Hui ink billets from two big ink industries were selected. We tried to find the fast and efficient drying conditions of Hui ink and calculate effective diffusion coefficient by performing manual control of temperature and relative humidity (RH). Several dry kinetic models were fitted. A constant temperature incubator was utilized for temperature control, while humidification and dehumidification were implemented accordingly for RH control. Setups of 25 °C and 35 °C were designed, and a relative humidity of 60%, 65%, 70%, and 75% was applied for each temperature. The process of ink drying was recorded, and the drying effect of Hui ink was estimated through expert decision. The appropriate drying temperature and humidity of the Jinbuhuan(J) and Huangshansongyan(H) ink billets from Lao Hu Kai Wen Ink Industry are at (31.99 ± 1.41) °C and (55.84 ± 10.38)% RH, whereas those of the Songyantanhei(ST), Chunyouyan(CY), and Quansongyan(QS) ink billets from Ju Mo Tang Ink Industry are at (23.70 ± 2.19) °C and (60.56 ± 2.16)% RH or (34.56 ± 2.37) °C and (59.16 ± 6.38)% RH; Initial moisture content of Hui ink has great influence on the water loss in the drying process; The effective diffusion coefficient of the ink lump ranges from 8.41538E-07 to 1.95891E-06 m2·s-1, and increases mainly with the temperature's rising; Logarithmic model fits best of the chosen models.

    This Alternative Gallery feature introduces the photographic artist Professor Richard Sawdon Smith. Professor Sawdon Smith's work stems around a fascination with representations of anatomy that have been fuelled by his experience as a hospital patient. The work has allowed him to explore ideas through the use of medical illustrations which include early anatomical drawings, personal medical photography and facial modelling. The work highlights how such imagery can be used in the context of a patient seeking understanding and acceptance of ill health and disease using the body as a canvas on which to translate the experience.

    This text is a portrayal of one of the greatest scientists of the late 20th-century, which also provides a picture of the significant physics of the period. It combines personal anecdotes, writings and recollections with narrative. Richard Feynman's career included: war-time work on the atomic bomb at Los Alamos; a theory of quantum mechanics for which he won the Nobel prize; and major contributions to the sciences of gravity, nuclear physics and particle theory. In 1986, he was able to show that the Challenger disaster was due to the effect of cold on the booster rocket rubber sealings.

    Described by his peers as the "finest physicist of his generation," Richard Feynman defied scientist stereotypes. This brash New York-born American physicist startled the more conservative giants of European physics with his endless ability to improvise. Indeed, later in life, Feynman became an accomplished bongo player. Feynman's legacy to physics was his ability to simplify complex equations and clarify fundamental principles through the use of graphs. He developed the theory of quantum electrodynamics, which illustrates the behavior of electrically charged particles, such as elect

    Richard T. Cox's contributions to the foundations of probability theory and inductive logic are not generally appreciated or understood. This paper reviews his life and accomplishments, especially those in his book The Algebra of Probable Inference and his final publication Inference and Inquiry which, in this author's opinion, has the potential to influence in a significant way the design and analysis of self organizing systems which learn from experience. A simple application to the simulation of a neuron is presented as an example of the power of Cox's contribution.

    2008-02-01

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

    2012-11-01

    Full Text Available Writing on the occasion of a retrospective of Richard Dunn’s work, Terence Maloon argued that ‘structuralism had an important bearing on virtually all of Richard Dunn’s mature works’, with ‘his modular, “crossed” formats’ being the most obvious manifestation of this. In this article I wish to reconsider this relation, withdrawing from a broad consideration of the framework of structuralism to focus on some of the quite particular ideas that Lacan proposed in response to structuralism. Beginning from a pivotal painting in the 1960s that developed out of Dunn’s experience of viewing the work of Barnett Newman, I wish to suggest a relation between the ongoing exploration of the thematic of scale in Dunn’s work and the idea of the symbolic that Lacan derives from structuralist thought. This relation, I argue, opens up a different way of understanding the art historical transition from Minimalism to Conceptual art.

    Full Text Available The Ningxia Hui Autonomous Region, located in Northwestern China, has the highest concentration of Hui Muslims in China: around 34% of the local population is Hui Muslim. Following the anti-religious campaigns of the communist regime and the wide destruction of the Cultural Revolution, Hui Muslims began gradually to reclaim their Muslim heritage in the late 70's. A major aspect of the rediscovery of their Islamic heritage was the Rehabilitation and reconstruction of Islamic Architectural buildings. As of today, Ningxia counts 4,500 mosques and other religious buildings. The present article seeks to introduce the architectural tendencies at play in this reconstruction, specifically the role of competing Arabic and Chinese influences.

    Full Text Available The era in which we live, characterized by multiculturalism and complexity, it is a time when it is clear the difficulty of man to orient and to choose their own way. It’s the time of the fall of every certainty, is the era of “post”, after the tradition, after metaphysics, after the truth, and that requires more effort than any other constant reflection. The neopragmatismo seems to be an effective investigative tool for conducting this reflection and a vantage point to carry on a conversation around the issues of education. In particular, the author intended to refer to the work of Richard Rorty, the author who more than others reflected on the encounter between two important pragmatist tradition: that of classical pragmatism and the “continental” or responsible for the development of a new European concept of truth, understood as a critical and interpretative.

Rorty was not engaged with moral philosophy in the systematic manner common among leading modern and contemporary moral philosophers. This paper has two parts: first part, in brief, is concerned with principles of his philosophy such as anti-essentialism, Darwinism, Freudism, and historicism. Second part which be long and detailed, considers many moral themes in Rorty's thought such as critique of Kantian morality, solidarity, moral progress, cruelty and concept of other, etc. Subsequently, I will try to answer the research question of the article namely, has Rorty a moral philosophy?

    Richard D. Schwartz, Professor Emeritus of Astronomy, died at his home in Sequim, WA, after a nearly 3 year battle against pancreatic cancer. Richard was born in Pretty Prairie, Kansas. He was active in sports and band and graduated in 1959. After completing a BS at Kansas State, and a Master's degree in Divinity at Union Seminary in NY, he further studied astrophysics, receiving his doctorate from University of Washington in 1973. When Dick arrived at the University of Missouri-St. Louis in 1975, he was the only astronomer in the Department of Physics. He built the astronomy program and initiated the B.S. in physics with an astrophysics option that the majority of physics majors choose. Dick was a wonderful teacher and provided outstanding leadership to the campus. He designed and provided oversight on the construction of the campus observatory that was completed in 1981. Since that time the observatory has served as both a teaching and research facility. It is also used for monthly public open houses that draw hundreds of people annually to the campus to view the moon, stars, and planets. Upon his retirement in 2003, the Board of Curators approved naming the campus observatory the "Richard D. Schwartz Observatory" in honor of his distinctive service to the University of Missouri-St. Louis. Just as important as Dick's service to promote public interest in astronomy was his effort to make the campus observatory a research facility. Dick equipped and maintained the observatory with state-of-art detectors that allowed students to get their first taste of scientific research. From 1991-2003, he managed the campus program for the NASA/Missouri Space Grant Consortium and mentored over 30 research students in projects at the observatory. Some of the results have been published in astronomical journals. Many of those students went on to graduate schools and several have achieved tenure and distinction at major universities. In addition to Dick's service to the University

    2003-01-01

    An axial focusing surface muon channel, Dai Omega, was installed at KEK-MSL in the summer of 2001. Large aperture superconducting coils are utilized instead of quadrupole magnets. Dai Omega adopts an axial focusing beam path using symmetric magnetic fields from four coils. Computer simulations were performed on constructing Dai Omega, and the calculated solid angle acceptance of Dai Omega was larger than 1 sr at the optimum momentum. The momentum acceptance of Dai Omega was 6% FWHM. Dai Omega improved the solid angle acceptance by almost 20 times, in comparison with conventional muon channels. Beam tuning tests of Dai Omega have been carried out, and a beam intensity of 10 6 μ + /s was achieved at KEK-NML (500 MeV, 5 μA), which was almost comparable with that of RAL (800 MeV, 200 μA)

  20. Richard Murphy: a life in writing

    Directory of Open Access Journals (Sweden)

    E. Meihuizen

    2006-07-01

    Full Text Available The Irish poet Richard Murphy published his autobiography “The kick: a life among writers” in 2003. From a slightly different perspective the subtitle of this work could be rewritten as “A life in writing” since it is an account of the agencies that moulded a life devoted to creative writing which forms the book’s essential impetus. The memoir is based on notebooks which Murphy kept throughout his life “to hold the scraps of verse, elusive images, dreams, desires and revelations” to be developed into poetry. Apart from contextualising his poetry by registering the relationships, circumstances and landscapes from which it germinated, Murphy also tells of the creative process itself and the personal poetics underlying this process. This article explores what is regarded as the central determining feature of Murphy’s identity as poet, namely the relationship between the creative self and a particular place, where the concept of “place” is seen as a cultural palimpsest which represents not only physical qualities, but also the shaping and development of the landscape through time according to a certain way of life.

  1. Richard Murphy: Autobiography and the Connemara landscape

    Directory of Open Access Journals (Sweden)

    Elsa Meihuizen

    2015-08-01

    Full Text Available It could be argued that an important feature of Richard Murphy’s work, and of his identity as a poet is the relationship between the creative self and a particular place, where ‘place’ should be understood as referring not just to physical qualities of the natural environment, but in a broader sense to denote an environment in which everything is interrelated and connected, and in which there is no sharp division between the natural and the human. The landscape providing inspiration for Murphy’s poetic imagination is the landscapes and seascapes of Connemara in north-west Ireland. In 1959 he settled in this environment which was to be his base for the next 20 years and from this period and this location emanated the bulk of his poetic oeuvre. For Murphy committing to a life of writing poetry necessarily means being in the Connemara landscape. Returning to this environment in adulthood represents a quest for recovering childhood feelings, of belonging and love, as connected to particular places. Murphy’s Connemara poems could be read as an account of this process of re-placement, as a type of autobiographical text in which the artist creates a ‘double portrait’: in writing about the landscape he also writes about himself, creating a place-portrait which is, at the same time, a self-portrait.

We must, he claims, avoid two misconceptions: ‘empiricism’ and ‘abstract theory’. In the first case, theory is reduced to the task of summarizing the outcome of empirical......It is a rare event when a new general field of research opens up within sociology. However, with this book, Richard Swedberg intends to do just that. It is not just another book on social theory. It is a book on ‘theorizing’. And that makes all the difference. Swedberg has chosen the term ‘art......’, but also ‘craft’, to emphasize the practical side of doing theory. This topic has been strangely absent, not just in sociology but in the social sciences in general. In order to see this absence, we should ask ourselves how education in sociology is conventionally organized. The answer is by a taken...

    Full Text Available Polycystic ovary syndrome (PCOS is one of the most common endocrine-metabolic disorders. Evidence of familial aggregation analysis and different clinical traits among different regions and ethnicities indicated that the pathogenesis of PCOS is associated with multiple genetic and environmental factors. Our previous research had identified three susceptibility loci (rs2479106, DENND1A; rs13405728, LHCGR; rs13429458, THADA for PCOS in Han Chinese women. The overall aim of this study was to investigate the relationship between three susceptibility gene polymorphisms and PCOS in Hui ethnic women.151 patients with PCOS (case group and 99 healthy women (control group were recruited from the Reproductive Medicine Center of the General Hospital of Ningxia Medical University. Clinical data and serum hormone characteristics of case and control groups were collected and analyzed. The three susceptibility single-nucleotide polymorphisms have been replicated in both case and control groups. Gene polymorphisms were detected by direct sequencing after polymerase chain reaction.The Body Mass Index, LH, LH/FSH ratio and total testosterone were significantly elevated in PCOS patients compared to control group (P0.05.The present study suggested that the SNP rs13405728 in the LHCGR gene was associated with PCOS in Hui ethnic women, and its TT genotype characterized with higher level of TT, TG and LDL.

    Ulcerative colitis (UC) is a chronic inflammatory bowel disease that may become intractable when treated with conventional medications such as aminosalicylates, corticosteroids, and azathioprine. The herbal medicine Qing Dai has traditionally been used in Chinese medicine to treat UC patients, but there is a lack of published data on the efficacy of Qing Dai in UC treatment. We report several cases of patients with intractable UC who take Qing Dai in a retrospective observational study. Furthermore, we explore the mechanisms of action of Qing Dai. Nine patients with active UC who received conventional medications but wished to receive Qing Dai as an alternative medication were included in our analysis. The UC severity level was determined based on the clinical activity index (CAI). Additionally, 5 of the 9 patients were endoscopically evaluated according to the Matts grading system. Each patient received 2 g/d of Qing Dai orally and continued taking other medications for UC as prescribed. Electron spin resonance was applied to explore the mechanisms of action of Qing Dai. After 4 mo of treatment with Qing Dai, the CAI score decreased from 8.3 ± 2.4 to 2.4 ± 3.4 (mean ± SD; P Qing Dai possesses strong hydroxyl radical scavenging activity. Qing Dai showed significant clinical and endoscopic efficacy in patients who failed to respond to conventional medications. Scavenging of hydroxyl radicals appears to be a potential mechanism through which Qing Dai acts, but the significance of the scavenging ability of Qing Dai with respect to the anti-inflammatory effect in UC patients warrants further investigation.

    2007-12-01

    Dr. Richard B. Dunn, astronomer emeritus at the National Solar Observatory, died of a heart attack on September 29, 2005. He was recognized as one of the foremost experimental solar physicists. His innovative designs for telescopes and instruments led to many important discoveries in solar physics. Born in Baltimore, Maryland, in 1927 and raised in Minneapolis, Minnesota, Dick's parents were Dr. Halbert L. Dunn and Katherine Brandner. Halbert (MD, Ph.D., F.A.P.H.A.) was an physician who became Chief of the National Office of Vital Statistics, Public Health Service. He published a paper "High Level Wellness for Man and Society" that became the founding paper of the field of wellness health care. After their divorce in 1942, Katherine moved to New York and became a social worker. Dick had two older brothers who died before him, Halbert (born in 1921, who became a civil engineer) and Robert (born in 1924, who became an architect). Dick earned a BS in mechanical engineering and an MS in astronomy at the University of Minnesota. At the end of World War II he served in the United States Army in Japan. For his master's degree, Dick undertook the design and construction of a Lyot-type birefringent filter for observations of solar prominences. This early work led to his acceptance at Harvard, where Professor Donald Menzel encouraged him to continue his work with the 15-inch Cambridge telescope. In 1951 he conducted part of his doctoral thesis work at the fledgling Sacramento Peak Observatory in southern New Mexico. The observatory director, Dr. John Evans, was impressed with Dick's outstanding instrumental talents and invited him to join as one of the first scientific staff members. During his first few years at Sac Peak, Dick developed two more birefringent filter systems including one with an integrated coronagraph. With this system, he produced the best prominence and spicule observations ever obtained. Dick's career was dedicated to obtaining solar observations of the

    Full Text Available Objectives: The Medical Outcomes Study HIV Health Survey (MOS-HIV is frequently used in HIV clinical trials; however, scores generated from the MOS-HIV are not suited for cost-effectiveness analyses as they do not assign utility values to health states. Our objective was to estimate and externally validate several mapping algorithms to predict Health Utilities Index Mark 3 (HUI3 and EQ-5D-3L utility values from the MOS-HIV. Methods: We developed and validated mapping algorithms using data from two HIV clinical trials. Data from the first trial (n = 367 formed the estimation data set for the HUI3 (4,610 observations and EQ-5D-3L (4,662 observations mapping algorithms; data from the second trial (n = 168 formed the HUI3 (1,135 observations and EQ-5D-3L (1,152 observations external validation data set. We compared ordinary least squares (OLS models of increasing complexity with the more flexible two-part, beta regression, and finite mixture models. We assessed model performance using mean absolute error (MAE and mean squared error (MSE. Results: The OLS model that used MOS-HIV dimension scores along with squared terms gave the best HUI3 predictions (mean observed 0.84; mean predicted 0.80; MAE 0.0961; the finite mixture model gave the best EQ-5D-3L predictions (mean observed 0.90; mean predicted 0.88; MAE 0.0567. All models produced higher prediction errors at the lower end of the HUI3 and EQ-5D-3L score ranges (<0.40. Conclusions: The proposed mapping algorithms can be used to predict HUI3 and EQ-5D-3L utility values from the MOS-HIV, although greater error may pose a problem in samples where a substantial proportion of patients are in poor health. These algorithms may be useful for estimating utility values from the MOS-HIV for cost-effectiveness studies when HUI3 or EQ-5D-3L data are not available.

Field visits, a questionnaire and in situ inspections were conducted in 2012–2014 to understand people’s perception and awareness of drought and its impact, particularly with respect to adaptation strategies. We mainly focused on drought adaptation actions and planning implemented at the government level under the double pressures of drought and allocation. We described a suitable adaptation pathway for socio-economic sustainable development and discussed existing adaptation barriers. Construction of modern efficient water-saving agriculture lies at the core of drought adaptation, with socio-economic sustainable development being the ultimate goal. To achieve this, policies and institutional, engineering, technological, structural and social initiatives and measures—classified into macro adaptation strategies and specific coping measures—are implemented. Adaptation often encounters obstacles, e.g., policy issues from household contract responsibility systems, funding difficulties of low-income farmers, traditional behavioral habits and low education and literacy levels among farmers. The adaptation pathway involves the construction of modern efficient water-saving agriculture. Agricultural water savings are then transferred to developed industries, which back-feed socio-economic sustainable development in the NX region.

    2012-07-15

    This report is an appendix to the Hawaii WindHUI efforts to dev elop and operationalize short-term wind forecasting and wind ramp event forecasting capabilities. The report summarizes the WindNET field campaign deployment experiences and challenges. As part of the WindNET project on the Big Island of Hawaii, AWS Truepower (AWST) conducted a field campaign to assess the viability of deploying a network of monitoring systems to aid in local wind energy forecasting. The data provided at these monitoring locations, which were strategically placed around the Big Island of Hawaii based upon results from the Oahu Wind Integration and Transmission Study (OWITS) observational targeting study (Figure 1), provided predictive indicators for improving wind forecasts and developing responsive strategies for managing real-time, wind-related system events. The goal of the field campaign was to make measurements from a network of remote monitoring devices to improve 1- to 3-hour look ahead forecasts for wind facilities.

    The objective of this document is to identify some lessons learned from the Fukushima Dai-ichi accident for PSA. Based on the public information on the causes that have led to major radioactive release during the Fukushima Dai-ichi accident (initiating events, material and human response), the authors, ASAMPSA-E WP30 members have performed a review to examine the gaps/insufficiencies/incompleteness in the existing Level 1 and Level 2 PSAs. This is the aim of this report which is one of WP30 deliverables i.e. D30.2. The consideration of external initiating events for the different levels of defense-in-depth is one of the focal points in this review. Recommendations in the way of developing the different elements of PSAs have been proposed by the authors and were completed later during the ASAMPSA-E project. Moreover, first recommendations on the use of PSA information in decision making have been included as well. (authors)

    Based on the data of Ningxia Hui Autonomous Region forest resources inventory, field investigation and laboratory analysis, this paper studied the carbon sequestration status of forest ecosystems in Ningxia region, estimated the carbon density and storage of forest ecosystems, and analyzed their spatial distribution characteristics. The results showed that the biomass of each forest vegetation component was in the order of arbor layer (46.64 Mg x hm(-2)) > litterfall layer (7.34 Mg x hm(-2)) > fine root layer (6.67 Mg x hm(-2)) > shrub-grass layer (0.73 Mg x hm(-2)). Spruce (115.43 Mg x hm(-2)) and Pinus tabuliformis (94.55 Mg x hm(-2)) had higher vegetation biomasses per unit area than other tree species. Over-mature forest had the highest arbor carbon density among the forests with different ages. However, the young forest had the highest arbor carbon storage (1.90 Tg C) due to its widest planted area. Overall, the average carbon density of forest ecosystems in Ningxia region was 265.74 Mg C x hm(-2), and the carbon storage was 43.54 Tg C. Carbon density and storage of vegetation were 27.24 Mg C x hm(-2) and 4.46 Tg C, respectively. Carbon storage in the soil was 8.76 times of that in the vegetation. In the southern part of Ningxia region, the forest carbon storage was higher than in the northern part, where the low C storage was mainly related to the small forest area and young forest age structure. With the improvement of forest age structure and the further implementation of forestry ecoengineering, the forest ecosystems in Ningxia region would achieve a huge carbon sequestration potential.

    An explosion on the Sun in 1859, serendipitously witnessed by amateur astronomer Richard Carrington, plunged telegraphic communications into chaos and bathed two thirds of the Earth's skies in aurorae. Explaining what happened to the Sun and how it could affect Earth, 93 million miles away, helped change the direction of astronomy. From being concerned principally with charting the stars to aid navigation, astronomers became increasingly concerned with what the celestial objects were, how they behaved and how they might affect life on Earth.

  11. Bridging the Knowledge Gaps between Richards' Equation and Budyko Equation

    Science.gov (United States)

    Wang, D.

    2017-12-01

    The empirical Budyko equation represents the partitioning of mean annual precipitation into evaporation and runoff. Richards' equation, based on Darcy's law, represents the movement of water in unsaturated soils. The linkage between Richards' equation and Budyko equation is presented by invoking the empirical Soil Conservation Service curve number (SCS-CN) model for computing surface runoff at the event-scale. The basis of the SCS-CN method is the proportionality relationship, i.e., the ratio of continuing abstraction to its potential is equal to the ratio of surface runoff to its potential value. The proportionality relationship can be derived from the Richards' equation for computing infiltration excess and saturation excess models at the catchment scale. Meanwhile, the generalized proportionality relationship is demonstrated as the common basis of SCS-CN method, monthly "abcd" model, and Budyko equation. Therefore, the linkage between Darcy's law and the emergent pattern of mean annual water balance at the catchment scale is presented through the proportionality relationship.

    2004-01-01

    Full Text Available Quality of life is an important indicator in assessing the burden of disease, especially for chronic conditions. The Health Utilities Index (HUI is a recently developed system for measuring the overall health status and health-related quality of life (HRQL of individuals, clinical groups, and general populations. Using the HUI (constructed based on eight attributes: vision, hearing, speech, mobility, dexterity, cognition, emotion, and pain/discomfort to measure the HRQL for chronic disease patients and to detect possible associations between HUI system and various chronic conditions, this study provides information to improve the management of chronic diseases.This study is of interest to data analysts, policy makers, and public health practitioners involved in descriptive clinical studies, clinical trials, program evaluation, population health planning, and assessments. Based on the Canadian Community Health Survey (CCHS for 2000–01, the HUI was used to measure the quality of life for individuals living with various chronic conditions (Alzheimer/other dementia, effects of stroke, urinary incontinence, arthritis/rheumatism, bowel disorder, cataracts, back problems, stomach/intestinal ulcers, emphysema/COPD, chronic bronchitis, epilepsy, heart disease, diabetes, migraine headaches, glaucoma, asthma, fibromyalgia, cancers, high blood pressure, multiple sclerosis, thyroid condition, and other remaining chronic diseases. Logistic Regression Model was employed to estimate the associations between the overall HUI scores and various chronic conditions. The HUI scores ranged from 0.00 (corresponding to a state close to death to 1.00 (corresponding to perfect health; negative scores reflect health states considered worse than death. The mean HUI score by sex and age group indicated the typical quality of life for persons with various chronic conditions. Logistic Regression results showed a strong relationship between low HUI scores (≤ 0.5 and 0.06

Hua-Zheng-Hui-Sheng-Dan (HZHSD was used as an experimental model to explore research methods of large formulae in traditional Chinese medicine (TCM using current molecular biology approaches. Materials and Methods. The trypan blue exclusion assay was used to determine cell viability and cell numbers. Flow cytometry was used to assess cell cycle distribution and apoptosis. The concentration of cyclin D1 was analyzed by enzyme-linked immunosorbent assay. The median effect principle was used in drug combination studies. An orthogonal experimental design was used to estimate the effects of each herb at different concentrations. The HeLa xenograft mouse model was used to compare the antitumor activity of drugs in vivo. Results. Among the 35 herbs that comprise HZHSD, Radix Rehmanniae Preparata (RRP, Caesalpinia sappan (CS, Evodia rutaecarpa (ER, Folium Artemisiae Argyi (FAA, Leonurus japonicus Houtt (LJH, Tumeric (Tu, Radix Paeoniae Alba (RPA, and Trogopterus Dung (TD effectively inhibited the proliferation of HeLa and SKOV3 cells. Only RRR had an effect on HeLa and SKOV3 cell viability. According to the median effect principle, Angelica sinensis (Oliv. (AS, Tabanus (Ta, and Pollen Typhae (PT, which were proven to have a significant synergistic inhibitory effect on the proliferation of HeLa cells, were added to the original eight positive herbs. The combination of RPA and AS had a synergistic effect on inducing cell cycle S phase arrest and decreasing intracellular cyclin D1 in HeLa cells. By orthogonal experimental design, LJH and Tu were considered unnecessary herbs. The small formula (SHZHSD consisted of RPA, AS, RRR, Ta., TD, PT, ER, CS, and FAA and was able to inhibit cell proliferation and induce cell apoptosis. The antitumor effects of HZHSD and SHZHSD were also compared in vivo. Conclusions.

  16. Transaction Pattern Based on Secondary Clientelism, Business Ideology and Market Development: The case of lime market in Hui Town

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    Secondary clientelism is a special exchange relationship derived from primary clientelism. The market with transactions dependent on the secondary clientelism would be”because of”erembeddedness”. Using the lime market in Hui Town as a case, this paper tries to explore why this kind of markets could achieve market order from the perspective of the interconnection of market structure and market culture. Analysis demonstrates that, the coupling induction of structural embeddedness and cultural embeddedness is the deeper mechanism for the market development. Although the new business ideology and transactional dependence on networks originate from market structural transitions, active construction and choice behaviors of the manufacturers still manifest great importance.

    Richard Dawkins will speak on biology, Gerard ‘t Hooft will focus on physics, and Alain Connes will discuss mathematics. CERN scientists probe ever-deeper levels of matter and their interactions, but can we say that the patterns they see are truly fundamental? Does the universe obey the same laws throughout? Since mathematical constructions can be true in the absence of any relation to the physical world, is mathematics more fundamental than physics? Extraterrestrial life would probably look much different from that on Earth, but natural selection still be fundamental to their evolution?

    monitoring using PMU devices and enhanced grid analysis tools; and Initiative 3: Identifying grid automation and smart technology architecture retrofit/improvement opportunities following a systematic review approach, inclusive of increasing renewables and variable distributed generation. Each of the initiative was conducted in partnership with industry technology and equipment providers to facilitate utility deployment experiences inform decision making, assess supporting infrastructure cost considerations, showcase state of the technology, address integration hurdles with viable workarounds. For each initiative, a multi-phased approach was followed that included 1) investigative planning and review of existing state-of-the-art, 2) hands on deployment experiences and 3) process implementation considerations. Each phase of the approach allowed for mid-course corrections, process review and change to any equipment/devices to be used by the utilities. To help the island grids transform legacy infrastructure, the Wind HUI provided more systematic approaches and exposure with vendor/manufacturers, hand-on review and experience with the equipment not only from the initial planning stages but through to deployment and assessment of field performance of some of the new, remote sensing and high-resolution grid monitoring technologies. HELCO became one of the first utilities in the nation to install and operate a high resolution (WindNet) network of remote sensing devices such as radiometers and SODARs to enable a short-term ramp event forecasting capability. This utility-industry and federal government partnership produced new information on wind energy forecasting including new data additions to the NOAA MADIS database; addressed remote sensing technology performance and O&M (operations and maintenance) challenges; assessed legacy equipment compatibility issues and technology solutions; evaluated cyber-security concerns; and engaged in community outreach opportunities that will

  6. The Paradox of the Public Realm in Richard Rorty

    2008-12-01

    Full Text Available The concepto of the public sphere in Richard Rorty's philosophy, inherited of liberal tradition, allows be treated as a part of a game of language called democratic liberalism. One of the rules for validating a move in this game consists in taking for granted the distinction between the public and the private spheres. Richard Rorty thought that democratic liberalism did not need any foundation beyond the way to play it; its only criteria would be the game's practices, according an utopia which would allow us to make more movements in the game. That is, democratic liberalism does not require foundations, but just practices for achieving a social hioe inspired on freedom and pluralism. This kind of utopia, based upon the non-cruelty principle, would make possible an inclusive society where everyone would have a place for their own private vocabulary. In this way, Rorty would have linked freedom and solidarity. However, this language-game reveals the paradox of the link which implies the meaning of the public shere. Herein, freedom is not a sufficient condition of solidarity; hence, there is no place for social inclusion in Rorty's language game.

  7. Argument from Design in Richard Baxter's Natural Theology

    Full Text Available The article deals with the teleological argument, or argument from design, as expounded by a famous English Protestant theologian Richard Baxter, one of the leading 17-th century English Puritans, in his work “The Reasons of the Christian Religion”. Natural theology, providing arguments for the existence of God based on reason and without appeal to the Revelation, has always played a vital role throughout the entire history of theological thought. The most popular was the so called teleological argument, or the argument from design, which stands out among all rational arguments for the existence of the Creator. It is mostly known from the “Fifth Way” of the medieval Scholastic philosopher Thomas Aquinas and a famous work “Natural Theology” by an English 19-th century theologian William Paley. The foundation for the modern research in the area was laid during the age of the Scientific Revolution of the 17th century English nature philosophers and theologians, especially Robert Boyle, who believed the teleological argument to be the key element of Natural Theology. His friend and confessor, Richard Baxter, a prominent representative of the Puritan Natural Theology, mostly known by his theological works, paved the way for Natural Theology both in his own time and the following centuries. His work was thought to be the best collection of the evidences for Christianity.

    Robert L. Miller

    2006-03-01

    Full Text Available Handling Qualitative Data: A Practical Guide is an introductory textbook covering all stages of qualitative research from the initial conceptualisation of a project, through data collection and analysis, to writing up. The author, Lyn RICHARDS, is a well-known developer of two key qualitative software analysis packages, NUD*IST and NVivo. While RICHARDS clearly advocates the use of qualitative analysis software, the text is "generic" and could be used in tandem with any qualitative software package. The book concentrates on practical advice about the use of software to manage and analyse qualitative data, and provides insights in these areas. The consideration of issues around team-based qualitative research is another strong point. However, due in part to its short length, the overall coverage of topics tends to be superficial. In itself, the book does not provide sufficient detailed support for a student who would like to use it as her/his main source of guidance for carrying out a qualitative research project.

Such care is available courtesy of the Barefoot College, a pioneering NGO that transforms the skills of the illiterate poor into local infrastructure. Barefoot Doctors are innovative because of their origins as dais (traditional midwives; once abundant across South Asia, dais are mostly extinct due to government/NGO interventions emphasizing “modernity”, like the Accredited Social Health Activist program. Why, then, have dais survived as Barefoot Doctors when they are extinct elsewhere? Ecological niche differentiation refers to when competing species successfully coexist; one species adapts to fulfill another role. Using over fifty interviews with stakeholders, I explain the persistence of Barefoot Doctors as health resources using “professional niche differentiation”. Barefoot Doctors exemplify how health infrastructure can be sustainable in resource-poor settings when created according to local needs and ideologies.

    Full Text Available El concepto de lo público en Richard Rorty, heredero de la tradición liberal, admite ser tratado como parte de un juego del lenguaje denominado liberalismo democrático. En ese sentido, una de las reglas de este juego para saber si una jugada es válida consiste en asumir la distinción entre esfera pública y privada. Richard Rorty pensó que este juego no requería fundamentación más allá de la forma de jugarlo, que el criterio en que se apoyaría estaba en las prácticas que tienen lugar dentro del mismo con arreglo a sostener una utopía que permitiera hacer cada vez más jugadas. Esto es, el liberalismo democrático no requería basarse en algo más allá de las prácticas conducentes a lograr una esperanza social alentada por la libertad en defensa del pluralismo. Su utopía liberal, guiada por el principio de la no-crueldad, haría posible una sociedad inclusiva en la que todos tuvieran espacio para su léxico privado. De este modo, Rorty habría vinculado libertad y solidaridad, pero su juego del lenguaje permite advertir la paradoja del vínculo que implicaría el sentido de lo público. Aquí, la libertad no es condición suficiente de la solidaridad, de modo que la inclusión social no tiene cabida en su juego del lenguaje.

    The majority of research about tobacco use in China focuses on Han Chinese, the main ethnic group comprising over 90 per cent of the population, and a paucity of research exists on ethnic minorities. The present study elucidates tobacco use among the Dai people, an ethnic group in Yunnan Province, Southwest China. The study design consisted of interviews and grounded theory methodology in a symbolic interactionist theoretical framework. The categories of the grounded theory revealed tobacco consumption was weaved in a complex web of meanings: social practices, perceptions of health, and work lives as agriculturalists, situated in Dai cultural and social milieu. An important finding was the stage-managing of tobacco as a symbol of 'tradition' versus 'modernity': Through a process of contested modernity, the older men championed long-standing tobacco customs as representative of Dai heritage and thus their own tobacco use as upholding traditions amid encroaching cultural and societal change in China. These findings are important because little is known about Dai people's tobacco use and how they are responding to social change. There are also implications for the development of culturally-appropriate tobacco control strategies. © 2015 Foundation for the Sociology of Health & Illness.

    Treatments with nonsteroidal anti-inflammatory drugs (NSAIDs) have increased the number of patients with gastrointestinal complications. Qing Dai has been traditionally used in Chinese herbal medicine for various inflammatory diseases such as ulcerative colitis. We previously reported that Qing Dai suppressed inflammations by scavenging reactive oxygen species (ROS) in ulcerative colitis patients. Thus, Qing Dai can attenuate the production of ROS, which play an important role in NSAID-induced gastrointestinal injuries. In this study, we aimed to elucidate whether Qing Dai decreased mitochondrial ROS production in NSAID-treated gastrointestinal cells by examining cellular injury, mitochondrial membrane potentials, and ROS production with specific fluorescent indicators. We also performed electron paramagnetic resonance measurement in isolated mitochondria with a spin-trapping reagent (CYPMPO or DMPO). Treatments with indomethacin and aspirin induced cellular injury and mitochondrial impairment in the gastrointestinal cells. Under these conditions, mitochondrial alterations were observed on electron microscopy. Qing Dai prevented these complications by suppressing ROS production in gastrointestinal cells. These results indicate that Qing Dai attenuated the ROS production from the NSAID-induced mitochondrial alteration in the gastrointestinal epithelial cells. Qing Dai treatment may be considered effective for the prevention NSAID-induced gastrointestinal injury.

    2017-03-01

    Full Text Available Whatever else it takes to drive a taxi, it takes trust. Day after day, the driver has to decide whether the other is or is not trustworthy. I take the taxi as a test case to analyze and assess Richard Kearney’s diacritical hermeneutics of the other. I argue that Kearney functionalizes the concept of transcendence in order to connect the transcendence of the finite other to the transcendence of the infinite other. However, in his central critique of the deconstructionists following Jacques Derrida, Kearney counters his connection. While Kearney’s critique of Derrida’s account of absolute alterity is correct and compelling, I argue that Derrida’s critique of a distinction between the trustworthy other and the non-trustworthy other might be more crucial than Kearney contends. Insisting on openness to the other’s otherness, Derrida provokes any hermeneutic of the other to trust in transcendence. The taxi is taken as a test to illustrate the implications which diacritical and deconstructive drivers might have for evaluating the entanglement of ethics and eschatology—inside and outside the taxi.

    Full Text Available This article aims at explaining the recent history of Peru, in an exercise in which it is possible to extract lessons about the way Latin American democracies have been(or have not been forged. The text draws a parallel between the ideas developed by Richard Rorty in his recently published book, Forjar nuestro país. El pensamiento de izquierdas en los Estados Unidos del siglo XX, and the events in Fugimori's and Montesinos' Peru. If, according to what Rorty believes, "national pride is for the countries what self esteem is for individuals ... " how would it be possible to narrate a history in which there are few motives to be proud of? Trying to escape fatalism and sarcasm, the text tries to show that Montesino's political course is, symbolically, a summary of the decomposition process of Peruvian democracy. Secondly, the text analyses the movements of the political left wing and deals with the support the regimen received from inside and outside the country, a support that was largely based on the illusion of political stability. Finally, it states, as Rorty does, that in order to forge democracies it is necessary for us to be deeply committed to the defense of the State of Right.

    Full Text Available Le roman de Richard Powers, Operation Wandering Soul (1993, présente le lien subtil qui associe un mondialisme déjà usé et vieillissant à l’enfant perçu comme catégorie dominante. Comme les faces serpentines d’un ruban de Möbius lové autour de l’illimité et de l’intemporel, le texte, tendu entre ses deux infinis – l’univers et l’enfant – révise la portée, la conception, la structure et le style du genre romanesque. Délaissant Aristote pour Einstein, Operation Wandering Soul se place sur le terrain de la cosmologie. Le récit, qui rassemble la kyrielle des grands ralliements juvéniles et leurs vains pèlerinages, concentre l’espace-temps dans une présentation qui évoque la « somme des histoires » de Richard Feynman. La contraction de l’espace-temps opérée par le roman ne fait pas de celui-ci un hymne simpliste au global (catégorie déjà aussi datée que celle des malheureux vétérans du Vietnam, mais capte au contraire la conscience grandissante d’une existence sans origine qui s’étend à perte de vue au-delà de ses coordonnées supposées. Le roman s’enroule sur lui-même tout en s’épanchant au dehors, boucle ses cadres et ses détours tout en desserrant leur emprise. Il fait tourner la roue de ses récits comme des planètes en rotation, la ronde d’un système solaire, le tourbillon d’une galaxie. La conscience que présente Operation Wandering Soul ne se résume donc pas au seul point de vue de l’âme errante qu’est le personnage de Kraft, mais consiste en la somme de tous les temps et de tous les lieux, de leurs strates accumulées comme une conscience en acte, complexe et tissée de réseaux, qui n’appartient à personne et est partagée par tous. Cette accumulation organise le jeu des perspectives multiples qui instaurent l’acte de lecture et sont instaurées par lui.

  12. PolyRES: A polygon-based Richards equation solver

    International Nuclear Information System (INIS)

    Hills, R.G.

    1995-12-01

    This document describes the theory, implementation, and use of a software package designed to solve the transient, two-dimensional, Richards equation for water flow in unsaturated-saturated soils. This package was specifically designed to model complex geometries with minimal input from the user and to simulate groundwater flow related to assessment of low-level radioactive waste disposal sites and engineered facilities. The spatial variation of the hydraulic properties can be defined across individual polygon-shaped subdomains, called objects. These objects combine to form a polygon-shaped model domain. Each object can have its own distribution of hydraulic parameters. The resulting model domain and polygon-shaped internal objects are mapped onto a rectangular, finite-volume, computational grid by a preprocessor. This allows the user to specify model geometry independently of the underlying grid and greatly simplifies user input for complex geometries. In addition, this approach significantly reduces the computational requirements since complex geometries are actually modeled on a rectangular grid. This results in well-structured, finite difference-like systems of equations that require minimal storage and are very efficient to solve. The documentation for this software package includes a user's manual, a detailed description of the underlying theory, and a detailed discussion of program flow. Several example problems are presented that show the use and features of the software package. The water flow predictions for several of these example problems are compared to those of another algorithm to test for prediction equivalency

    The Jewish historian and theorist of medicine, Richard Koch, teaching in Frankfurt/Main, fled in 1936 from National Socialist Germany to the USSR where he lived in the Caucasian spa Essentuki until his death in 1949. Here he worked as a doctor and continued his scientific work, especially on the foundations of medicine in natural philosophy. None of his works of this time were published. Koch was a scientific outsider in the USSR, and he was aware of this. However, he tried to make his views compatible with official doctrines. In 1947 he lost his employment at the medical clinic of Essentuki, and his material situation grew worse. It is still an open question whether this development was related to an increasingly anti-Jewish atmosphere in the USSR that was linked with the Stalinist "purges", as Koch himself appeared to believe. Before his flight from Germany Koch did not show any tendency towards communism or the political left at all. His attitude towards Soviet society and Stalin was mixed: cautious criticism was accompanied by strong expressions of commitment to Stalin and Koch's new Socialist home. The question to what extent Koch's comments showed his true convictions must remain without a definite answer. At least in part they can be understood as precautions in threatening circumstances. The opportunity of a remigration to Germany after 1945, however, was turned down by Koch.

  14. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen

    Directory of Open Access Journals (Sweden)

    David J. Baker

    2017-05-01

    Full Text Available The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

    As a special form of social consciousness ,legal consciousness is the general name of people’ s thinking about the law and legal phenomena ,concepts ,ideas ,knowledge and psychology .Contemporary Hui ethnicity legal consciousness ,which is a special awareness of the law ,is different from legal con‐sciousness of Han nationality . Based on the empirical investigation of contemporary Hui ethnicity students’ legal consciousness ,this paper obtained the following causes of Hui ethnicity legal conscious‐ness:the cultural core settled dow n from the formation of the Hui nationality ,w hich survived from the Han cultural identity and change with its own characteristics ;sharia law and ethics contained in Koran and hadith is a determining factor on the formation of Hui ethnicity legal consciousness ;mosque education is a special educational support and place for Hui people learning and passing on their religious law .%法律意识是社会意识的一个特殊形式,是人们关于法和法律现象的思想、理念、观点、知识和心理的总和。当代回族法律意识作为一种特殊群体的法律意识有别于汉族法律意识。本文在实证调查基础之上,得出了以下回族法律意识成因:回族族群的形成过程中,与汉文化的认同与变迁中沉淀下来的“融而不化”、“和而不同”的文化内核;《古兰经》、“圣训”蕴含的伊斯兰教法及道德规范对回族法律意识观的形成具有决定因素;回族群众具有特殊的教育载体及特殊的宗教法传习场所———“经堂”。

  16. Failed Mothers, Monster Sons. Reading Shakespeare’S Richard Iii as a Fairy Tale

    Full Text Available The paper looks at Shakespeare’s historical play Richard III and its fairy tale-like character given by the configuration of the main character as an arch-villain and the presence of motifs and patterns typically associated with the fairy tale genre. More specifically, it considers the mother-son relationship between the Duchess of York and Richard in the light of the motif of monstrous birth. It is not a coincidence that the emergence of such motifs coincides with the historical contexts of the early modern period. Reading Richard III in this key is related to the revisionist approach to chronicle plays.

    Echinococcus transmission is known to be affected by various environmental factors, which may be modified by human influence or natural events including global warming. Considerable population growth in the last fifty years in Ningxia Hui Autonomous Region (NHAR), the People's Republic of China (PRC), has led to dramatic increases in deforestation and modified agricultural practices. In turn, this has resulted in many changes in the habitats for the definitive and intermediate hosts of both Echinococcus granulosus and E. multilocularis, which have increased the risks for transmission of both parasites, affecting echinococcosis prevalence and human disease. Ecological environmental changes due to anthropogenic activities and natural events drive Echinococcus transmission and NHAR provides a notable example illustrating how human activity can impact on a parasitic infection of major public health significance. It is very important to continually monitor these environmental (including climatic) factors that drive the distribution of Echinococcus spp. and their impact on transmission to humans because such information is necessary to formulate reliable future public health policy for echinococcosis control programs and to prevent disease spread.

    Full Text Available The objective of this study was to introduce application of the Richards equation on modelling and prediction of stand diameter distribution. The long-term repeated measurement data sets, consisted of 309 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata plantations in the southern China, were used. Also, 150 stands were used as fitting data, the other 159 stands were used for testing. Nonlinear regression method (NRM or maximum likelihood estimates method (MLEM were applied to estimate the parameters of models, and the parameter prediction method (PPM and parameter recovery method (PRM were used to predict the diameter distributions of unknown stands. Four main conclusions were obtained: (1 R distribution presented a more accurate simulation than three-parametric Weibull function; (2 the parameters p, q and r of R distribution proved to be its scale, location and shape parameters, and have a deep relationship with stand characteristics, which means the parameters of R distribution have good theoretical interpretation; (3 the ordinate of inflection point of R distribution has significant relativity with its skewness and kurtosis, and the fitted main distribution range for the cumulative diameter distribution of Chinese fir plantations was 0.4∼0.6; (4 the goodness-of-fit test showed diameter distributions of unknown stands can be well estimated by applying R distribution based on PRM or the combination of PPM and PRM under the condition that only quadratic mean DBH or plus stand age are known, and the non-rejection rates were near 80%, which are higher than the 72.33% non-rejection rate of three-parametric Weibull function based on the combination of PPM and PRM.

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation

  4. Expression of DAI by an oncolytic vaccinia virus boosts the immunogenicity of the virus and enhances antitumor immunity

    Full Text Available In oncolytic virotherapy, the ability of the virus to activate the immune system is a key attribute with regard to long-term antitumor effects. Vaccinia viruses bear one of the strongest oncolytic activities among all oncolytic viruses. However, its capacity for stimulation of antitumor immunity is not optimal, mainly due to its immunosuppressive nature. To overcome this problem, we developed an oncolytic VV that expresses intracellular pattern recognition receptor DNA-dependent activator of IFN-regulatory factors (DAI to boost the innate immune system and to activate adaptive immune cells in the tumor. We showed that infection with DAI-expressing VV increases expression of several genes related to important immunological pathways. Treatment with DAI-armed VV resulted in significant reduction in the size of syngeneic melanoma tumors in mice. When the mice were rechallenged with the same tumor, DAI-VV-treated mice completely rejected growth of the new tumor, which indicates immunity established against the tumor. We also showed enhanced control of growth of human melanoma tumors and elevated levels of human T-cells in DAI-VV-treated mice humanized with human peripheral blood mononuclear cells. We conclude that expression of DAI by an oncolytic VV is a promising way to amplify the vaccine potency of an oncolytic vaccinia virus to trigger the innate—and eventually the long-lasting adaptive immunity against cancer.

  5. Evaluation of re-criticality potential in Fukushima Dai-ichi reactors following core damage accidents

    The re-criticality potential of the debris-bed, formed of the degraded core materials, cannot be ruled out during the cooling-down procedure of the Fukushima Dai-ichi NPPs. In this study the re-criticality potential has systematically investigated based on the core disruption phase analysis using a IMPACT-SAMPSON code prepared by The Institute of Applied Energy (IAE). The results obtained for the re-criticality potential, characterized by the eigen-values k-eff dependent on the debris composition formed at the core, RPV bottom, and PCV pedestal, are reflected to the arguments on the re-criticality prevention measures, such as timing and concentration of boron-compounds, during the cooling-down process of the Fukushima Dai-ichi NPPs.

    This report is an appendix to the Hawaii WindHUI efforts to develop and operationalize short-term wind forecasting and wind ramp event forecasting capabilities. The report summarizes the WindNET Phase 1 efforts on the Big Island of Hawaii and includes descriptions of modeling methodologies, use of field validation data, results and recommendations. The objective of the WindNET project was to investigate the improvement that could be obtained in short-term wind power forecasting for wind generation facilities operating on the island grids operated by Hawaiian Electric Companies through the use of atmospheric sensors deployed at targeted locations. WindNET is envisioned as a multiphase project that will address the short-term wind forecasting issues of all of the wind generation facilities on the all of the Hawaiian Electric Companies' island grid systems. The first phase of the WindNET effort (referred to as WindNET-1) was focused on the wind generation facilities on the Big Island of Hawaii. With complex terrain and marine environment, emphasis was on improving the 0 to 6 hour forecasts of wind power ramps and periods of wind variability, with a particular interest in the intra-hour (0-1 hour) look-ahead period. The WindNET project was built upon a foundation that was constructed with the results from a previously completed observation targeting study for the Big Island that was conducted as part of a project supported by the National Renewable Energy Laboratory (NREL) and interactions with the western utilities. The observational targeting study provided guidance on which variables to measure and at what locations to get the most improvement in forecast performance at a target forecast site. The recommendations of the observation targeting study were based on the application two techniques: (1) an objective method called ensemble sensitivity analysis (ESA) (Ancell and Hakim, 2007; Torn and Hakim, 2008; Zack et al, 2010); and (2) a subjective method based on a

    Herrlin, K.; Stroemberg, T.; Lidgren, L.; Walloee, A.; Pettersson, H.

    Four hundred and thirty trochanteric factures operated upon with McLaughlin, Ender or Richard's osteosynthesis were divided into 6 different types based on their radiographic appearance before and immediately after reposition with special reference to the medial cortical support. A significant correlation was found between the fracture type and subsequent mechanical complications where types 1 and 2 gave less, and types 4 and 5 more complications. A comparison of the various osteosyntheses showed that Richard's had significantly fewer complications than either the Ender or McLaughlin types. For Richard's osteosynthesis alone no correlation to fracture type could be made because of the small number of complications in this group.

    Deng, Rui; Lyttleton, Chris

    2013-01-01

    In one county of Southwest China bordering Myanmar, large numbers of minority Dai women leave to work in southern Thailand. Many are married and they leave behind husbands and children, sending remittances and returning home intermittently. These women commonly establish relations with Chinese/Malaysian men in their worksites--massage parlours in the tourist sites near the Malaysian border. These men become second husbands just as the Dai women become second wives. This paper examines the complicated set of HIV risks and assumptions that emerge from the circular Dai exodus to Thailand and the manner in which transnational employment networks impact on domestic and sexual relationships for women and their non-migrant husbands back home.

    Orally administered Qing-dai, called indigo naturalis in Latin, is reportedly useful for the treatment of ulcerative colitis. We herein describe two patients with ulcerative colitis who developed colitis with wall thickening and edematous changes during oral administration of the powdered form of Qing-dai. In Case 1, a 35-year-old man developed colitis similar to ischemic colitis with bloody stool that recurred each time he ingested Qing-dai. He had no signs of recurrence upon withdrawal of Qing-dai. In Case 2, a 43-year-old woman underwent ileocecal resection for treatment of an intussusception 2 months after beginning oral administration of Qing-dai. Edema and congestion but no ulceration were present in the mucosa of the resected specimen. Both patients exhibited abdominal pain with bloody diarrhea, and abdominal computed tomography showed marked wall edema affecting an extensive portion of the large bowel.

    The parameters in Richards' equation are usually calculated from experimentally measured values of the soil-water characteristic curve and saturated hydraulic conductivity. The complex pore structures that often occur in porous media complicate such parametrization due to hysteresis between wetting and drying and the effects of tortuosity. Rather than estimate the parameters in Richards' equation from these indirect measurements, image-based modelling is used to investigate the relationship between the pore structure and the parameters. A three-dimensional, X-ray computed tomography image stack of a soil sample with voxel resolution of 6 μm has been used to create a computational mesh. The Cahn-Hilliard-Stokes equations for two-fluid flow, in this case water and air, were applied to this mesh and solved using the finite-element method in COMSOL Multiphysics. The upscaled parameters in Richards' equation are then obtained via homogenization. The effect on the soil-water retention curve due to three different contact angles, 0°, 20° and 60°, was also investigated. The results show that the pore structure affects the properties of the flow on the large scale, and different contact angles can change the parameters for Richards' equation.

    2009-01-01

    Dai-kenchu-to (DKT) has attracted attention as a drug that improves the symptoms of postoperative ileus. However, the detailed mechanism of its action still remains unknown. The effect of DKT on colonic motility was herein evaluated using an original method. Eight healthy male volunteers who understood the purpose of this study were enrolled. Dai-kenchu-to (5 g) was dissolved in saline and administered into the cecum using a colonoscope until the ascending colon became distended. Colonic motility was observed by extrasomatic ultrasonography for 30 min. Colonic contractions were observed 129.4 (range 110-145) s after DKT administration into the ascending colon. Every segment in the right colon divided by the crescentic folds contracted independently. On the other hand, no colonic contractions were observed in the right colon after saline solution alone was administered to the ascending colon. In conclusion, DKT stimulates colonic motility immediately after administration, in the same manner as it does for the upper alimentary tract.

    Dai ethnicity is one of the major Chinese ethnic minorities with a population of about 1.2 million. We aimed to determine the prevalence and potential causes of visual impairment (VI) among ethnic Dai adults aged 50 years or older in a rural community in China. A population-based survey including 2163 ethnic Dai people (80.5%) was undertaken using a random cluster sampling strategy. The detailed eye examination was performed after pupil dilation by trained study ophthalmologists and optometrists. Presenting visual acuity (PVA) and best-corrected visual acuity (BCVA) was measured using the Early Treatment Diabetic Retinopathy Study logMAR chart and VI was defined as a VA of less than 20/63 in the better-seeing eye. The overall prevalence of presenting blindness and low vision was 3.0% (95% CI, 2.3-3.7) and 13.3% (95% CI, 11.9-14.8), respectively. The prevalence estimates were reduced to 2.1% (95% CI, 1.5-2.8) and 6.7% (95% CI, 5.7-7.8) when BCVA was considered. Men were more likely to be affected by low vision but less likely to be blind compared with women. Cataract accounted for 62.7% of presenting low vision and 68.8% of presenting blindness, respectively. In conclusion, VI was a significant health concern in Dai Chinese in China.

    The aim of the present study was to study the effect and mechanism of action of intraduodenal and intrajejunal dai-kenchu-to, an herbal medicine clinically effective for uncomplicated postoperative adhesive intestinal obstruction, on upper gastrointestinal motility. Five mongrel dogs were equipped with four strain-gauge force transducers on the antrum, duodenum, and proximal and distal jejunum to measure contractile activity. Dai-kenchu-to (0.5, 1.5, and 3.0 g) was administered into the duodenal or proximal jejunal lumen. The effect of atropine, hexamethonium, phentolamine, propranolol, and ondansetron on intraduodenal and intrajejunal dai-kenchu-to-induced contractions was studied. Plasma motilin was measured by specific radioimmunoassay. Intraduodenal and intrajejunal dai-kenchu-to induced phasic contractions in the duodenum and proximal jejunum, respectively, and those contractions migrated distally. Phasic contractions induced by intraduodenal and intrajejunal dai-kenchu-to were inhibited by atropine and hexamethonium at all sites. Plasma motilin was not affected by dai-kenchu-to. Intraduodenal and intrajejunal dai-kenchu-to stimulates upper gastrointestinal motility at and distal to the administration sites through cholinergic receptors.

    The Great East Japan Earthquake on March 11, 2011 generated a series of large tsunami that seriously damaged the Fukushima Dai-ichi Nuclear Power Plant (FDNPP), which resulted in the release of radioactive materials into the environment. To provide further details regarding the distribution of air dose rate and the distribution of radioactive cesium ((134)Cs and (137)Cs) deposition on the ground within a radius of approximately 5 km from the nuclear power plant, we carried out measurements using an unmanned helicopter equipped with a radiation detection system. The distribution of the air dose rate at a height of 1 m above the ground and the radioactive cesium deposition on the ground was calculated. Accordingly, the footprint of radioactive plumes that extended from the FDNPP was illustrated. Copyright © 2014 Elsevier Ltd. All rights reserved.

  13. The Fukushima Dai-ichi Accident and its implications for the safety of nuclear power

    2016-05-01

    Five years ago the dramatic events in Fukushima that followed the massive earthquake and subsequent tsunami that struck Japan on March 11, 2011 sharpened the focus of scientists, engineers and general public on the broad range of technical, environmental and societal issues involved in assuring the safety of the world's nuclear power complex. They also called into question the potential of nuclear power to provide a growing, sustainable resource of CO2-free energy. The issues raised by Fukushima Dai-ichi have provoked urgent concern, not only because of the potential harm that could result from severe accidents or from intentional damage to nuclear reactors or to facilities involved in the nuclear fuel cycle, but also because of the extensive economic impact of those accidents and of the measures taken to avoid them.

  14. An update on radioactive release and exposures after the Fukushima Dai-ichi nuclear disaster.

    2012-09-01

    On 11 March 2011, the Richter scale 0.9-magnitude Tokohu earthquake and tsunami struck the northeast coast of Japan, resulting in widespread injury and loss of life. Compounding this tragic loss of life, a series of equipment and structural failures at the Fukushima Dai-ichi nuclear power plant (FDNP) resulted in the release of many volatile radioisotopes into the atmosphere. In this update, we detail currently available evidence about the nature of immediate radioactive exposure to FDNP workers and the general population. We contrast the nature of the radioactive exposure at FDNP with that which occurred at the Chernobyl power plant 25 years previously. Prediction of the exact health effects related to the FDNP release is difficult at present and this disaster provides the scientific community with a challenge to help those involved and to continue research that will improve our understanding of the potential complications of radionuclide fallout.

    The severe accident that broke out at Fukushima Dai-ichi nuclear power stations on March 11, 2011, caused seemingly infinite damage to the daily life of residents. Serious and wide-spread contamination of the environment occurred due to radioactive materials discharged from nuclear power stations (NPSs). At the same time, many issues were highlighted concerning countermeasures to severe nuclear accidents. The accident is outlined, and lessons learned are extracted with respect to the safety of NPSs, as well as radiation protection of residents under the emergency involving the accident.

    The great east Japan earthquake and subsequent tsunamis caused Fukushima Dai-ichi Nuclear Power Plant (NPP) accident. National Institute of Radiological Sciences (NIRS) developed the external dose estimation system for Fukushima residents. The system is being used in the Fukushima health management survey. The doses can be obtained by superimposing the behavior data of the residents on the dose rate maps. For grasping the doses, 18 evacuation patterns of the residents were assumed by considering the actual evacuation information before using the survey data. The doses of the residents from the deliberate evacuation area were relatively higher than those from the area within 20 km radius. The estimated doses varied from around 1 to 6 mSv for the residents evacuated from the representative places in the deliberate evacuation area. The maximum dose in 18 evacuation patterns was estimated to be 19 mSv.

    Radioactive emissions into the atmosphere from the damaged reactors of the Fukushima Dai-ichi nuclear power plant (NPP) started on March 12th, 2011. Among the various radionuclides released, iodine-131 (131I) and cesium isotopes (137Cs and 134Cs) were transported across the Pacific toward the North...... period and spatial variations across more than 150 sampling locations in Europe made it possible to characterize the contaminated air masses. After the Chernobyl accident, only a few measurements of the gaseous 131I fraction were conducted compared to the number of measurements for the particulate...... reactors have provided a significant amount of new data on the ratio of the gaseous 131I fraction to total 131I, both on a spatial scale and its temporal variation. It can be pointed out that during the Fukushima event, the 134Cs to 137Cs ratio proved to be different from that observed after the Chernobyl...

    Written few weeks after the accident, this article first recalls the circumstances (earthquake and tsunami), and then describes the accidental process within the primary vessels of the Fukushima Dai-ichi number 1, 2 and 3 reactors. The author then describes the interventions which aimed at cooling these three reactors, the problem faced for the storage of used fuels, and then the sequence of accidents: loss of cooling means leading to an explosion, problems faced in the different storage pools. He describes the various steps of recovery (primary cooling, electricity supply), discusses the consequences in terms of radioactivity releases in the plant environment with a comparison with Chernobyl, and also in terms of nature and quantity of radioactive elements. He comments radioactivity controls and measurements, evacuation measures, measurements performed by the IAEA, measurements of sea radioactivity, and the establishment of maps of ground radioactivity around the plant. He discusses the perspectives associated with these measurements for the surroundings of the Fukushima site

  19. How did Fukushima-Dai-ichi core meltdown change the probability of nuclear accidents?

    International Nuclear Information System (INIS)

    Escobar Rangel, Lina; Leveque, Francois

    2012-10-01

    How to predict the probability of a nuclear accident using past observations? What increase in probability the Fukushima Dai-ichi event does entail? Many models and approaches can be used to answer these questions. Poisson regression as well as Bayesian updating are good candidates. However, they fail to address these issues properly because the independence assumption in which they are based on is violated. We propose a Poisson Exponentially Weighted Moving Average (PEWMA) based in a state-space time series approach to overcome this critical drawback. We find an increase in the risk of a core meltdown accident for the next year in the world by a factor of ten owing to the new major accident that took place in Japan in 2011. (authors)

    This paper summarizes the activities of the National Atmospheric Release Advisory Center (NARAC) during the Fukushima Dai-ichi nuclear power plant crisis. NARAC provided a wide range of products and analyses as part of its support including: (1) Daily Japanese weather forecasts and hypothetical release (generic source term) dispersion predictions to provide situational awareness and inform planning for U.S. measurement data collection and field operations; (2) Estimates of potential dose in Japan for hypothetical scenarios developed by the Nuclear Regulatory Commission (NRC) to inform federal government considerations of possible actions that might be needed to protect U.S. citizens in Japan; (3) Estimates of possible plume arrival times and dose for U.S. locations; and (4) Plume model refinement and source estimation based on meteorological analyses and available field data. The Department of Energy/National Nuclear Security Administration (DOE/NNSA) deployed personnel to Japan and stood up 'home team' assets across the DOE complex to aid in assessing the consequences of the releases from the Fukushima Dai-ichi Nuclear Power Plant. The DOE Nuclear Incident Team (NIT) coordinated response activities, while DOE personnel provided predictive modeling, air and ground monitoring, sample collection, laboratory analysis, and data assessment and interpretation. DOE deployed the Aerial Measuring System (AMS), Radiological Assistance Program (RAP) personnel, and the Consequence Management Response Team (CMRT) to Japan. DOE/NNSA home team assets included the Consequence Management Home Team (CMHT); National Atmospheric Release Advisory Center (NARAC); Radiation Emergency Assistance Center/Training Site (REAC/TS); and Radiological Triage. NARAC was activated by the DOE/NNSA on March 11, shortly after the Tohoku earthquake and tsunami occurred. The center remained on active operations through late May when DOE ended its deployment to Japan. Over 32 NARAC staff

  1. Limited awareness of animal influenza prevention and control among Dai Lue smallholder farmers in Southwest China.

    2017-10-01

    Awareness of animal influenza and its prevention and control is important for ensuring livestock health, production and welfare. In China, a country stereotyped as a major source of emerging zoonotic infectious diseases, research on the public understanding of animal influenza is limited to the Han, the main ethnic group. The present qualitative study in Southwest China investigated awareness of animal influenza among the Dai, an ethnic minority. The participants (15 men and 10 women, ages 18-83) were smallholder farmers of pigs and poultry in rural areas of Jinghong, Xishuangbanna, Yunnan Province. A mixture of interviews and group discussions took place in homes and villages. The participants were asked about their knowledge of avian influenza (H7N9), swine influenza (H1N1), precautions taken to protect against influenza, procedures when animals were sick and perceived risk of animal influenza. The data were analysed following coding and thematic analysis. The findings demonstrated a limited understanding of animal health and welfare among participants. Specifically, they were largely unaware of animal influenza (H7N9, H1N1) including its causes, symptoms, prevention and treatment. The farmers were also uninformed of the risks they faced and unknowingly engaged in behaviours which increased direct or indirect exposure to infected animals, a risk factor for human infection. They also reported poor usage of veterinary services. In order to guarantee the health, welfare and production of their livestock, immediate action is needed to enable Dai smallholder farmers to prevent and respond to animal influenza effectively and timely.

    This paper summarizes the activities of the National Atmospheric Release Advisory Center (NARAC) during the Fukushima Dai-ichi nuclear power plant crisis. NARAC provided a wide range of products and analyses as part of its support including: (1) Daily Japanese weather forecasts and hypothetical release (generic source term) dispersion predictions to provide situational awareness and inform planning for U.S. measurement data collection and field operations; (2) Estimates of potential dose in Japan for hypothetical scenarios developed by the Nuclear Regulatory Commission (NRC) to inform federal government considerations of possible actions that might be needed to protect U.S. citizens in Japan; (3) Estimates of possible plume arrival times and dose for U.S. locations; and (4) Plume model refinement and source estimation based on meteorological analyses and available field data. The Department of Energy/National Nuclear Security Administration (DOE/NNSA) deployed personnel to Japan and stood up 'home team' assets across the DOE complex to aid in assessing the consequences of the releases from the Fukushima Dai-ichi Nuclear Power Plant. The DOE Nuclear Incident Team (NIT) coordinated response activities, while DOE personnel provided predictive modeling, air and ground monitoring, sample collection, laboratory analysis, and data assessment and interpretation. DOE deployed the Aerial Measuring System (AMS), Radiological Assistance Program (RAP) personnel, and the Consequence Management Response Team (CMRT) to Japan. DOE/NNSA home team assets included the Consequence Management Home Team (CMHT); National Atmospheric Release Advisory Center (NARAC); Radiation Emergency Assistance Center/Training Site (REAC/TS); and Radiological Triage. NARAC was activated by the DOE/NNSA on March 11, shortly after the Tohoku earthquake and tsunami occurred. The center remained on active operations through late May when DOE ended its deployment to Japan. Over 32 NARAC staff members

    The accident at Fukushima Dai-ichi Nuclear Power Station caused by the Great East Japan Earthquake and tsunami in March 2011 had a major impact on the safeguards situation at the site. JSGO, NMCC, TEPCO and JAEA are tackling the challenges posed by the accident jointly with the IAEA and in cooperation with the US Department of Energy (DOE). From the day of the earthquake, JSGO and the IAEA have shared information on decommissioning activities and discussed how to deal with this difficult issue. In May 2012, the Fukushima Task Force was established. Its objective is to develop a holistic approach to safeguards implementation measures for the site, to monitor the re-establishment of safeguards, to facilitate discussion of relevant issues, and to consider possible approaches to longer-term safeguards challenges. All the fuels in spent fuel ponds in Units 5 and 6 and Common Spent Fuel Storage have been successfully re-verified. Re-verification of fuels kept in spent fuel pond in Unit 4 is underway. A special arrangement called SNOS (Short Notice Operational Support Activities) has been introduced to confirm non-diversion of declared material at Fukushima Dai-ichi site. Based on extensive information exchange, proactive discussions on safeguards approaches are being held for near-term issues. The damaged core material in Units 1-3 will pose extreme difficulties in longer-term. A special sub-group has been established under the task force to address the issues. Although lessons learned from past nuclear accidents resulting in damage of core material have some relevance, none of them can be directly applicable for Fukushima. Thus a foresighted and creative approach is needed. Close coordination with the IAEA and support from technically competent institutions in Japan and from abroad, such as DOE, are also essential to tackle the issues. (author)

    Chinese herbal medicine Qing-Dai (also known as indigo naturalis) has been used to treat various inflammatory conditions. However, not much has been studied about the use of oral Qing-Dai in the treatment for ulcerative colitis (UC) patients. Studies exploring alternative treatments for UC are of considerable interest. In this study, we aimed at prospectively evaluating the safety and efficacy of Qing-Dai for UC patients. The open-label, prospective pilot study was conducted at Keio University Hospital. A total of 20 patients with moderate UC activity were enrolled. Oral Qing-Dai in capsule form was taken twice a day (daily dose, 2 g) for 8 weeks. At week 8, the rates of clinical response, clinical remission, and mucosal healing were 72, 33, and 61%, respectively. The clinical and endoscopic scores, CRP levels, and fecal occult blood results were also significantly improved. We observed 2 patients with mild liver dysfunction; 1 patient discontinued due to infectious colitis and 1 patient discontinued due to mild nausea. This is the first prospective study indicating that oral Qing-Dai is effective for inducing remission in patients with moderate UC activity and can be tolerated. Thus, Qing-Dai may be considered an alternative treatment for patients, although further investigation is warranted. © 2016 S. Karger AG, Basel.

    Full Text Available Adhesive small bowel obstruction (ASBO is an adverse consequence of abdominal surgery. Although the Kampo medicine Dai-kenchu-to is widely used in Japan for treatment of postoperative ASBO, rigorous clinical studies for its use have not been performed. In the present retrospective observational study using the Japanese diagnosis procedure combination inpatient database, we selected 288 propensity-score-matched patients with early postoperative ASBO following colorectal cancer surgery, who received long-tube decompression (LTD with or without Dai-kenchu-to administration. The success rates of LTD were not significantly different between Dai-kenchu-to users and nonusers (84.7% versus 78.5%; P=.224, while Dai-kenchu-to users showed a shorter duration of LTD (8 versus 10 days; P=.012, shorter duration between long-tube insertion and discharge (23 versus 25 days; P=.018, and lower hospital charges ($23,086 versus $26,950; P=.018 compared with Dai-kenchu-to nonusers. In conclusion, the present study suggests that Dai-kenchu-to is effective for reducing the duration of LTD and saving costs.

    My post-structuralist feminist reading of the antenatal and birthing practices of women (N = 25) living in a basti in India makes visible how the meanings of maternal experiences constituted as our ways open discursive spaces for the mothers and dais as procreators to: challenge (i.e., question the authority of), co-opt (i.e., conditionally adopt), and judge (i.e., employ sanctioned criteria to regulate) competing knowledge production forms. In critiquing maternal knowledge as feminist discourse, the women's strategies contribute theoretically to an integrative construction of care by reclaiming displaced knowledge discourses and diversity in meaning production. Pragmatically, consciousness-raising collectives comprising the mothers and dais can cocreate narratives of our ways of maternal experiences articulated in public discourse to sustain equitability of knowledge traditions in migrant urban Third World contexts.

    2018-05-01

    La « Sémiologie Graphique » de Bertin est un ouvrage majeur de la cartographie contemporaine. Cependant, dès sa parution en 1967, cet ouvrage a suscité autant d'intérêt que de méfiance : l'ouvrage n'était pas dans le « moule » de la littérature cartographique en vigueur. Pourtant, si plusieurs de ses principes et concepts fondateurs ont été adoptés, plusieurs autres ne sont pas bien passés ou n'ont pas été mis en pratique. Il y a comme un fossé entre certains énoncés théoriques de l'ouvrage et leur mise en pratique. Certaines affirmations de Bertin peuvent paraître obsolètes aujourd'hui à l'heure du numérique, comme la non prise en compte de l'aspect dynamique ou interactif de la carte. L'avènement récent des SIG, de la géomatique et des systèmes de Cartographie Assistée par Ordinateur a relégué les vieilles méthodes de traitement graphique de l'information au second rang. Dès lors pourquoi traduire encore aujourd'hui, à l'heure du numérique, la « Sémiologie Graphique » ? Justement, d'abord, parce que certains principes restent, en substance, peu connus ; plusieurs aspects demeurent encore à explorer ; certaines méthodes et techniques manuelles délaissées peuvent être revisitées et remises en marche grâce à la visualisation ; des innovations n'ont pas été expérimentées ou implémentées par les moyens numériques. Dans le monde arabe, peu de recherches se sont imprégnées de sémiologie graphique. Lors de la traduction de l'ouvrage en arabe, des points restés obscurs ont été décelés. Ce sont ces quelques idées et réflexions qui nous ont poussés à revivre cette formidable aventure.

    2003-05-01

    Richard Rufus of Cornwall offered a novel solution to the problem of mixture raised by Aristotle. The puzzle is that mixts or mixed bodies (blood, flesh, wood, etc.) seem to be unexplainable through logic, even though the world is full of them. Rufus's contribution to this long-standing theoretical debate is the development of a modal interpretation of certain Averroistic doctrines. Rufus's account, which posits that the elemental forms in a mixt are in accidental potential, avoids many of the problems that plagued non-atomistic medieval theories of mixture. This paper is an initial examination of Rufus' account.

    The nuclear accidents in the world are very few among various types of operating facilities. However when an accident happened, we have learnt a lot to improve the philosophy, term, definitions, document preparation, equipment's requirement, supporting systems, awareness program and restriction etc. After Fukushima Dai-ichi we have learnt a lot, in this view this paper has been prepared to discuss for radiological protection aspects. Discussion: The probability of nuclear accidents is negligible but when happens, it opens new doors of lessons for radiological protection practices for occupational workers, emergency workers for damage control to prevent catastrophic situation/rescue to life saving actions and the member of the public. The Chernobyl and Three Mile Island accidents have provided a lot experiences for management of emergency situations, documentation, radiation emergency preparedness, emergency equipment's, concept of defense-in-depth, emergency planning zone (EPZ), accidental dose limits, estimation of source term and public dose, intervention levels, decision supporting system, remedial actions in public domain; decontamination of person, houses/building and land and etc. Recent Fukushima Dai-ichi accident in Japan was managed in appreciable manner but still new definitions and lessons for radiological protection have been emerged out. The present paper discusses difficulties w. r. t. the radiological aspects observed/faced by Japanese during nuclear crises. The accident introduced new terms as Natural Dose Rate Unit (NDRU), voluntary evacuation, deliberate evacuation area, restricted area and difference between evacuation zone and EPZ. The Fukushima accident has enforced worldwide regulators and operators to review the individual dose limit and amendment for raise in the dose limit during accident, availability of efficient/adequate quantities of personal dosimeter in public domain, collection arrangement of bulk amount of radioactive wastes

    The earthquake and tsunami on March 11, 2011 severely damaged the Fukushima Dai-ichi nuclear plant leading to the most severe nuclear incident since Chernobyl. Ongoing operations to cool the damaged reactors at the site have led to the generation of highly radioactive coolant water. This is currently mainly treated to remove Cs-137 and Cs-134 and passed through a reverse osmosis (RO) unit to reduce the salinity before being cycled back to the reactors. Because only the Cs isotopes are removed, the RO reject water still contains many radioactive isotopes and this has led to the accumulation of over 200,000 cubic meters (52 million gallons) of extremely contaminated water which is currently stored on site in tanks. EnergySolutions, in partnership with Toshiba, were contracted to develop a system to reduce 62 isotopes in this waste down to allowable levels. This was a significant technical challenge given the high background salt content of the wastewater, the variation in aqueous chemistry of the radioactive isotopes and the presence of non-active competing ions (e.g. Ca and Mg) which inhibit the removal of isotopes such as Sr-89 and Sr-90. Extensive testing was performed to design a suitable system that could meet the required decontamination goals. These tests were performed over a 6 month period at facilities available in the nearby Fukushima Dai-ni laboratory using actual waste samples. This data was then utilized to design a Multi Radioactive Nuclides Removal System (MRRS) for Fukushima which is a modified version of EnergySolutions' proprietary Advanced Liquid Processing System (ALPS)'. The stored tank waste is fed into a preliminary precipitation system where iron flocculation is performed to remove a number of isotopes, including Sb-125, Ru-106, Mn-54 and Co-60. The supernatant is then fed into a second precipitation tank where the pH is adjusted and the bulk of the Mg, Ca and Sr precipitated out as carbonates and hydroxides. After passing through a

    The name of Fukushima has now become well-known worldwide after Hiroshima and Nagasaki as the third place exposed to radiation in Japan. This radiation pollution has severely damaged the chief industries of Fukushima Prefecture, namely agriculture, fishery, and tourist industry. It has also stimulated strong anxious feelings among parents with young children. The accident has caused a critical situation in the psychiatric and mental health services in Fukushima as well. Five hospitals with psychiatric beds within 30 km from the Fukushima Dai-ichi Nuclear Power Plant were ordered to transfer their inpatients to other hospitals outside the designated 30 km-areas and to close down the hospitals immediately after the nuclear plant accident. In total, more than 800 psychiatric beds disappeared in an instant, and 1,228 persons including psychiatric inpatients and residents of elderly people nursing homes were transferred to other facilities far away. Rational explanation that low-level radiation in Fukushima will not do harm to people did not necessarily relieve existing anxiety among people. The terms 'safety' and 'relief' are usually used in combination; however, 'relief' was separated from 'safety' this time in Fukushima. People gradually began to feel 'relieved', when they themselves got involved in the cleaning work of radiation although its effect remained ambiguous. Now we have the following mental health problems after the 2011 Fukushima Dai-ichi nuclear power plant accident; recovery and maintenance of treatment systems for psychiatric patients in the affected areas, efforts for early detection and intervention of depression, severe stress disorder, adaptation disorder, and alcohol abuse which are expected to occur due to the earthquake and radiation pollution, prevention of suicides, relief from anxiety resulting from radiation pollution, adequate treatment of mental problems among children with long-term evacuation, prevention of fall in physical and mental

    Contamination of the marine environment following the accident in the Fukushima Dai-ichi nuclear power plant represented the most important artificial radioactive release flux into the sea ever known. The radioactive marine pollution came from atmospheric fallout onto the ocean, direct release of contaminated water from the plant and transport of radioactive pollution from leaching through contaminated soil. In the immediate vicinity of the plant (less than 500 m), the seawater concentrations reached 68 000 Bq.L −1 for 134 Cs and 137 Cs, and exceeded 100 000 Bq.L −1 for 131 I in early April. Due to the accidental context of the releases, it is difficult to estimate the total amount of radionuclides introduced into seawater from data obtained in the plant. An evaluation is proposed here, based on measurements performed in seawater for monitoring purposes. Quantities of 137 Cs in seawater in a 50-km area around the plant were calculated from interpolation of seawater measurements. The environmental halftime of seawater in this area is deduced from the time-evolution of these quantities. This halftime appeared constant at about 7 days for 137 Cs. These data allowed estimation of the amount of principal marine inputs and their evolution in time: a total of 27 PBq (12 PBq–41 PBq) of 137 Cs was estimated up to July 18. Even though this main release may be followed by residual inputs from the plant, river runoff and leakage from deposited sediments, it represents the principal source-term that must be accounted for future studies of the consequences of the accident on marine systems. The 137 Cs from Fukushima will remain detectable for several years throughout the North Pacific, and 137 Cs/ 134 Cs ratio will be a tracer for future studies. Highlights: ► Fukushima Dai-ichi accident is the most important artificial radioactive release flux into the sea. ► Quantities of 137 Cs in seawater are deduced from individual measurements. ► Local concentrations in

He also gave several cured case records. His book, featuring unique idea with good effect, was repeatedly printed and extensively distributed, exerting influence, more or less, on the plague monographs of later ages, and occupying important position in the history of plague on Lingnan and the whole country as well. His idea of "that poisons and static blood" in pathogenesis and therapeutic principle of antitoxicity and activating blood is coincided with the results of present day clinical and laboratory studies. His administration of medicines is heuristic to the therapy of critical cases with Chinese medicaments and to the recognition of pathogenesis, etiology, and treatment of modern plague as well as other diseases of similar etiology and pathognesis and is worth of further study.

    Echinococcus transmission is known to be affected by various environmental factors, which may be modified by human influence or natural events including global warming. Considerable population growth in the last fifty years in Ningxia Hui Autonomous Region (NHAR), the People’s Republic of China (PRC), has led to dramatic increases in deforestation and modified agricultural practices. In turn, this has resulted in many changes in the habitats for the definitive and intermediate hosts of both Echinococcus granulosus and E. multilocularis, which have increased the risks for transmission of both parasites, affecting echinococcosis prevalence and human disease. Ecological environmental changes due to anthropogenic activities and natural events drive Echinococcus transmission and NHAR provides a notable example illustrating how human activity can impact on a parasitic infection of major public health significance. It is very important to continually monitor these environmental (including climatic) factors that drive the distribution of Echinococcus spp. and their impact on transmission to humans because such information is necessary to formulate reliable future public health policy for echinococcosis control programs and to prevent disease spread.

    The key anticancer agent, CPT-11 (irinotecan hydrochloride), induces severe diarrhea clinically. We investigated the effect of a Kampo medicine, Dai-kenchu-to (DKT), on CPT-11-induced intestinal injuries in rats. Twenty-four male Wistar rats were divided into three groups: a control group; a CPT-11 group, given CPT-11 150 mg/kg intraperitoneally for 2 days; and a DKT group, given DKT 300 mg/kg orally for 5 days with CPT-11 150 mg/kg intraperitoneally on days 4 and 5. The rats were killed on day 6. Interleukin (IL)-1β, IL-12, interferon (IFN)-γ, and tumor necrosis factor-α expression in the small intestine of the CPT-11 group was significantly higher than that of the control group. Interleukin-1β and IFN-γ expression was improved significantly by DKT (P DKT (P DKT suppressed CPT-11 induced inflammatory cytokines and apoptosis in the intestinal mucosa and maintained the mucosal integrity.

    Dai-kenchu-to (DKT) is known as an herbal medicine used for postoperative ileus. However, no report exists about the effect of DKT on portal blood flow. The aim of this study is to clarify the influence of DKT on portal blood flow. To healthy volunteers (Healthy; n = 6), cirrhotic patients (Cirrhosis; n = 7) and liver-transplant patients (LTx; n = 3), DKT (2.5g) with 100mL of warm water was orally administrated in the DKT group, and only warm water was administrated in the control group. The portal blood flow rate (M-VEL: cm/sec.) and portal blood flow (Flow volume: mL/min.) was measured each time after administration using an ultrasonic Doppler method. Furthermore, the arterial blood pressure and heart rate was measured at the same time points. In the DKT group, a significant increase of M-VEL (120%) and flow volume (150%) 30 minutes after administration was observed in both Healthy and Cirrhosis in comparison with the control group. In LTx, there was also a significant increase of flow volume (128%) 30 minutes after administration. However, there was no change in average blood pressure and heart rate in all groups. DKT increases portal blood flow in early phase after oral administration without any significant changes in the blood pressure and heart rate.

    The gastrointestinal symptoms accompanying dysfunction of the remnant stomach were seen after pylorus-preserving operation. Against such complications, Dai-kenchu-to (DKT) is used, but scientific evidences for efficacy are poor. The effect of DKT on gastrointestinal motility and gastric emptying after pylorus-preserving operation was investigated. Using beagle dogs, the experimental models mimicking the state after pylorus-preserving pancreaticoduodenectomy were prepared. We sutured strain gauge transducers to the stomach, duodenum and jejunum and inserted indwelling tubes into the stomach. About 4 weeks after operation, DKT 0.1g/kg was administered during the fasting or fed state. At the same time, the gastric emptying was evaluated by the acetoaminophene method. In the fasting state, administration of DKT enhanced the gastrointestinal motility and accelerated gastric emptying. In the postprandial state, no apparent effect on motility was seen. DKT enhances the gastrointestinal motility after pylorus-preserving pancreaticoduodenectomy in the fasting state. The effect of DKT may not be related to the continuity of the intramural nerve.

    Radionuclides from the reactor accident at the Fukushima Dai-ichi Nuclear Power Plant were observed in the surface air at stations in Hanoi, Dalat and Ho Chi Minh City (HCMC) in Vietnam, about 4500 km southwest of Japan, during the period from March 27 to April 22, 2011. The maximum activity concentrations in the air measured at those three sites were 193, 33 and 37 μBq m -3 for 131 I, 134 Cs and 137 Cs, respectively. Peaks of radionuclide concentrations in the air corresponded to arrival of the air mass from Fukushima to Vietnam after traveling for 8 days over the Pacific Ocean. Cesium-134 was detected with the 134 Cs/ 137 Cs activity ratio of about 0.85 in line with observations made elsewhere. The 131 I/ 137 Cs activity ratio was observed to decrease exponentially with time as expected from radioactive decay. The ratio at Dalat, where is 1500 m high, was higher than those at Hanoi and HCMC in low lands, indicating the relative enrichment of the iodine in comparison to cesium at high altitudes. The time-integrated surface air concentrations of the Fukushima-derived radionuclides in the Southeast Asia showed exponential decrease with distance from Fukushima. (author)

    After the Fukushima Dai-ichi nuclear power plant accident on March 11, 2011, the radioactivity released from the accident was transported around the globe by atmospheric processes. The radioactivity monitoring program on atmospheric particulate in Lanzhou, China was activated by GSCDC to detect the input radionu-clides through atmospheric transport. Several artificial radionuclides were detected and measured in aerosol samples from March 26 to May 2, 2011. The peaked activity concentrations (in mBq/m3) were: 1.194 (131I), 0.231 (137Cs), 0.173 (134Cs) and 0.008 (136Cs), detected on April 6, 2011. The average activity ratio of 131I/137Cs and 134Cs/137Cs in air were 13.5 and 0.78. The significant increase of 137Cs activity concentration, one order of magnitude higher than pre-Fukushima accident levels, in ground level aerosol was observed in 2013, as its re-suspension from soil. The back-trajectory analysis simulated by NOAA-ARL HYSPLIT shows a direct transfer of the air masses released from Fukushima to Lanzhou across the Pacific Ocean, North America and Europe at the height close to 9000 m AGL. The value of effective dose for inhalation is close to one millionth of the annual limit for the general public.

    During the lifespan of a Municipal Solid Waste landfill, its leachate drainage system may get clogged. Then, as a consequence of rainfall, leachate generation and possibly leachate injection, the moisture content in the landfill increases to the point that a leachate mound could be created. Therefore, pumping the leachate becomes a necessary solution. This paper presents an original analysis of leachate pumping and injection in an instrumented well. The water table level around the well is monitored by nine piezometers which allow the leachate flow behaviour to be captured. A numerical model based on Richards equation and an exponential relationship between saturated hydraulic conductivity and depth is used to analyze the landfill response to pumping and injection. Decreasing permeability with depth appears to have a major influence on the behaviour of the leachate flow. It could have a drastic negative impact on the pumping efficiency with a maximum quasi-stationary pumping rate limited to approximately 1m 3 /h for the tested well and the radius of influence is less than 20m. The numerical model provides a reasonable description of both pumping and injection tests. However, an anomalous behaviour observed at the transition between pumping and recovery phases is observed. This could be due to a limitation of the Richards model in that it neglects the gas phase behaviour and other double porosity heterogeneous effects. Copyright © 2016 Elsevier Ltd.

  13. Wooing-Scenes in “Richard III”: A Parody of Courtliness?

    2009-11-01

    Full Text Available In the famous opening soliloquy of Shakespeare’s Richard III, Richard mightily voices his repugnance to “fair well-spoken days” and their “idle pleasures”. He realizes his physical deformity and believes that it sets him apart from others. He openly admits that he is “not shaped for sportive tricks, nor made to court an amorous looking-glass”. Yet, his monstrosity constitutes more perhaps of his aggressive masculine exceptionality rather than of his deformity. Richard’s bullying masculinity manifests itself in his contempt for women. In the wooing scenes we clearly see his pugnacious pursuit of power over effeminate contentment by reducing women to mere objects. Additionally, those scenes are interesting from a psychological viewpoint as they brim over with conflicting emotions. Therefore, the paper explores two wooing encounters of the play, which belong the best examples of effective persuasion and also something we may refer to as ‘the power of eloquence’.

    In order to study the slurry diffusion law during grouting, Richards unsaturated-saturated model was introduced, the definition of the grouting model is clear, the Richards model control equation was established, And the BP neural network was introduced, the improved fluid-solid coupling model was constructed, Through the use of saturated - unsaturated seepage flow model, As well as the overflow boundary iterative solution of the mixed boundary conditions, the free surface is calculated. Engineering practice for an example, with the aid of multi - field coupling analysis software, the diffusion law of slurry was simulated numerically. The results show that the slurry diffusion rule is affected by grouting material, initial pressure and other factors. When the slurry starts, it flows in the cracks along the upper side of the grouting hole, when the pressure gradient is reduced to the critical pressure, that is, to the lower side of the flow, when the slurry diffusion stability, and ultimately its shape like an 8. The slurry is spread evenly from the overall point of view, from the grouting mouth toward the surrounding evenly spread, it gradually reaches saturation by non-saturation, and it is not a purely saturated flow, when the slurry spread and reach a saturated state, the diffusion time is the engineering grouting time.

  15. Gamma radiation and radon concentration levels at the radioactive waste repositories 'Richard' and 'Bratrstvi'

    Owing to the fact that cosmic rays are shielded off, the photon equivalent dose rates in the corridors of the Richard repository are usually slightly lower than outside. However, in points close to barrels containing radioactive waste, the dose rates can reach values as high as tens of μSv/h. Because of high concentrations of natural radionuclides, the dose rates in the Bratrstvi repository is generally considerably higher, as much as 5 times the normal background value. Radon concentrations exhibit specific time variations which are modified by ventilation. Where ventilation is poor or absent, the radon concentrations are extremely high, viz. up to 30 and 300 kBq/m 3 in the Richard and Bratrstvi repositories, respectively. Personal exposure of workers depend on the total time spent underground and on the ventilation rate. While the contribution from photons can be kept below the relevant limits, the radon-related doses may be significant and even exceed the professional limits if no precautions are taken. (P.A.)

  16. The 1D Richards' equation in two layered soils: a Filippov approach to treat discontinuities

    The infiltration process into the soil is generally modeled by the Richards' partial differential equation (PDE). In this paper a new approach for modeling the infiltration process through the interface of two different soils is proposed, where the interface is seen as a discontinuity surface defined by suitable state variables. Thus, the original 1D Richards' PDE, enriched by a particular choice of the boundary conditions, is first approximated by means of a time semidiscretization, that is by means of the transversal method of lines (TMOL). In such a way a sequence of discontinuous initial value problems, described by a sequence of second order differential systems in the space variable, is derived. Then, Filippov theory on discontinuous dynamical systems may be applied in order to study the relevant dynamics of the problem. The numerical integration of the semidiscretized differential system will be performed by using a one-step method, which employs an event driven procedure to locate the discontinuity surface and to adequately change the vector field.

    To clarify the influence of Dai-Kenchu-To (DKT) on portal blood flow (PBF), PBF was continuously measured with Doppler ultrasound. Normal liver rats were divided into a DKT 90 mg/kg, DKT 270 mg/kg administered group, and control, while cirrhotic liver rats were divided into a DKT-LC 90 mg/kg administered group and Control-LC. The PBF was measured after the administration of either DKT or water for 60 min by laser Doppler flowmetry system. The PBF in the DKT 90 increased approximately 10 min after DKT was administrated, and elevated levels were maintained for approximately 10 min. A comparison of the increase in PBF by the calculating the area under the curve (AUC) revealed that flow was significantly higher in the DKT 90 compared to either the control or the DKT 270 (p DKT-LC and Control-LC. The AUC, revealed no significant difference between the DKT-LC and Control-LC. DKT induced an increase in PBF in normal livers; however, its effects were insufficient to increase PBF in the cirrhotic livers. No increase in the portal blood flow in the cirrhotic liver rats was probably the result of the cirrhotic liver, which had fibrotic change, and, therefore, may not have had sufficient compliance to accept the increasing blood flow volume from the intestinal tract. We suggested DKT has the potential to protect the liver by increasing PBF when the liver has either normal or mild to moderate dysfunction.

    Dai-kenchu-to (DKT), a traditional Japanese herbal medicine, is known to increase gastrointestinal motility and improve ileal function. We tested our hypotheses that (1) pretreatment with DKT would block the colorectal distention-induced visceromotor response in rats, and (2) pretreatment with DKT would attenuate colorectal distention-induced adrenocorticotropic hormone (ACTH) release and anxiety-related behavior. Rats were pretreated with vehicle or DKT (300 mg/kg/5 mL, per os). Visceromotor responses were analyzed using electromyography in response to colorectal distention (10, 20, 40, 60, and 80 mmHg for 20 seconds at 3-minutes intervals). Anxiety-related behavior was measured during exposure to an elevated-plus maze after colorectal distention. Plasma ACTH and serum corticosterone levels were measured after exposure to the elevated-plus maze. Colorectal distention produced robust contractions of the abdominal musculature, graded according to stimulus intensity, in vehicle-treated rats. At 40, 60, and 80 mmHg of colorectal distention, the visceromotor responses of DKT-treated rats was significantly lower than that of vehicle-treated rats. At 80 mmHg, the amplitude was suppressed to approximately one-third in DKT-treated rats, compared with that in vehicle-treated rats. Smooth muscle compliance and the velocity of accommodation to 60 mmHg of stretching did not significantly differ between the vehicle-treated and DKT-treated rats. Similarly, the DKT did not influence colorectal distention-induced ACTH release, corticosterone levels, or anxiety-related behavior in rats. Our results suggest that DKT attenuates the colorectal distention-induced visceromotor responses, without increasing smooth muscle compliance, ACTH release or anxiety-related behavior in rats.

    The accident at the Fukushima Dai-ichi nuclear power plant (FD-NPP) on 11 March 2011 released large amounts of radioactivity into the atmosphere. We determine the total emission of the noble gas xenon-133 ( 133 Xe) using global atmospheric concentration measurements. For estimating the emissions, we used three different methods: (i) using a purely observation-based multi-box model, (ii) comparisons of dispersion model results driven with GFS meteorological data with the observation data, and (iii) such comparisons with the dispersion model driven by ECMWF data. From these three methods, we have obtained total 133 Xe releases from FD-NPP of (i) 16.7 ± 1.9 EBq, (ii) 14.2 ± 0.8 EBq, and (iii) 19.0 ± 3.4 EBq, respectively. These values are substantially larger than the entire 133 Xe inventory of FD-NPP of about 12.2 EBq derived from calculations of nuclear fuel burn-up. Complete release of the entire 133 Xe inventory of FD-NPP and additional release of 133 Xe due to the decay of iodine-133 ( 133 I), which can add another 2 EBq to the 133 Xe FD-NPP inventory, is required to explain the atmospheric observations. Two of our three methods indicate even higher emissions, but this may not be a robust finding given the differences between our estimates. - Highlights: ► We determine the total release of xenon-133 from the Fukushima nuclear accident. ► We used global measurements and a box model, as well as dispersion model estimates. ► Total 133 Xe release is about 14.2-19 EBq, more than Fukushima 133 Xe inventory. ► Additional release of iodine-133 and decay into 133 Xe needed to explain results.

    In the middle of the 20th century David Bohm and Richard Feynman developed two fundamentally different approaches of modern quantum mechanics: Bohm a realistic interpretation by means of hidden parameters and Feynman the path-integral formalism. This is by this more remarakable, because both physicists started from similar conditions and originated from similar connections. By its comparing approach this study presents more than a contribution to the history of the quantum theory. By the question for the social and cultural conditions of the formation of theories it is furthermore of science-sociological and science-theoretical interest. The in the beginning similar and later different binding of both scientists into the scientific community allows furthermore to study, which adapting pressure each group puts on the individual scientist and the fundamental parts of his research, and which new degrees of freedom in the formation of theories arise, when this constraint is cancelled.

    Richard Arwed Pfeifer (1877-1957) was one of the initiators and foster fathers of the renowned child-psychiatric and special needs education workgroup at Leipzig University under Paul Schröder (1873-1941) in the 1920s and 1930s. This paper is an account of their dispute concerning the interrelations between child and adolescent psychiatry and special needs education, as well as their disagreement about whether adolescent psychopaths should be admitted to specialized child psychiatric wards or elsewhere. Moreover, Pfeifer questioned the practical relevance of the separation of constitutional and environmentally-based psychopathy and fought eugenic research, which he found incompatible with the ethics of his profession as a remedial teacher and child psychiatrist.

The cause was the artificial openingof a new mouth about 5,5 km south of the original mouth, which increased tidal range and salinity. These swamp communities occupied a narrow band about 6 ha in area behind the Bruguiera gymnorrhiza Community. An estimated 95 % of the communities was affected and only on the landward border were some isolated remnants of species such as Acrostichum aureum, Hibiscus tiliaceus and Phoenix reclinata detected .Young stands of  Phragmites australis, seedlings of  Bruguiera gymnorrhiza and Avicennia marina and epipelic algae are recoIonizing the affected area.

  9. A critical review of Richard Lynn's reports on reaction time and race.

    Thomas, Drew M

    2011-01-01

    In the early 1990s, psychologist Richard Lynn published papers documenting average reaction times and decision times in samples of nine-year-olds taken from across the world. After summarizing these data, Lynn interpreted his results as evidence of national and racial differences in decision time and general intelligence. Others have also interpreted Lynn's data as evidence of racial differences in decision time and intelligence. However, comparing Lynn's summaries with his original reports shows that Lynn misreported and omitted some of his own data. Once these errors are fixed the rankings of nations in Lynn's datasets are unstable across different decision time measures. This instability, as well as within-race heterogeneity and between-race overlap in decision times, implies that Lynn's reaction time data do not permit generalizations about the decision times and intelligence of people of different races.

    In this article, we propose a computational method for solving the Lighthill-Whitham-Richards (LWR) partial differential equation (PDE) semi-analytically for arbitrary piecewise-constant initial and boundary conditions, and for arbitrary concave fundamental diagrams. With these assumptions, we show that the solution to the LWR PDE at any location and time can be computed exactly and semi-analytically for a very low computational cost using the cumulative number of vehicles formulation of the problem. We implement the proposed computational method on a representative traffic flow scenario to illustrate the exactness of the analytical solution. We also show that the proposed scheme can handle more complex scenarios including traffic lights or moving bottlenecks. The computational cost of the method is very favorable, and is compared with existing algorithms.

    Full Text Available In this timely book Richard Peet and his team lay the foundation with an excellent analysis of the process of globalisation and the resultant emergence of the global economy. The authors are especially critical of the increasing influence of institutions like the International Monetary Fund (IMF, World Bank and World Trade Organisation (WTO on the economy and the consequences experienced by peoples, cultures and the environment. The single ideology of neo-liberalism is blamed for the undesirable outcomes. This book considers concepts of power, political interest, hegemony, discourse, responsibility and the power of practicality, in critically examining the IMF, World Bank and WTO. The conclusion is reached that “all three institutions play roles greatly different from those originally agreed to under the charters that set them up”.

  15. BACK TO THE ORIGINS OF THE REPUDIATION OF WUNDT: OSWALD KÜLPE AND RICHARD AVENARIUS.

    2017-01-01

    This essay provides a fresh account of the break between Oswald Külpe and his master Wilhelm Wundt. Kurt Danziger's reconstruction of the "repudiation" of Wundt, which has become the canon for this significant episode of history of psychology, focused on the supposed influence of Ernst Mach on this set of events, overshadowing the other exponent of Empiriocriticism: Richard Avenarius. Analyzing archival documents and examining anew the primary sources, the paper shows that Avenarius was himself a member of Wundt's circle, and that his "repudiation" of the master paved the way for Külpe. The essay points out the original anti-Wundtian aspects of Avenarius' notion of psychology, thus showing how they were then adopted by Külpe. © 2016 Wiley Periodicals, Inc.

    Full Text Available Cet article interprète Gain, sixième roman de Richard Powers, à la lumière du concept de « seconde modernité » proposé par le sociologue allemand Ulrich Beck. Ce concept souligne la dissémination du risque et la manière dont celle-ci invalide les marchés conclus par la « première modernité » entre l’avenir et le présent, entre l’intérieur du corps et l’extérieur. Cet article entend montrer que Beck fournit un cadre interprétatif utile à la compréhension de ces rapports, hors des impasses catégorielles que suscite l’opposition entre les deux régimes narratifs à l’œuvre dans le texte : le récit biographique, local et individuel, de la maladie de Laura Rowen Bodey, et l’histoire collective de l’entreprise Clare devenue conglomérat.This essay interprets Richard Powers' sixth novel Gain with reference to the German sociologist Ulrich Beck's concept of “second modernity.” The concept underscores the dispersal of risk and how it shreds promissory notes understood in “first modernity” between the future and present and the insides and outsides of the body. It argues that Beck supplies an apt interpretive framework for understanding these relationships and overcoming the categorical impasses between the two narrative words at work in Power's novel, the biographical situatedness of Laura Rowen Bodey's illness and the corporate history of the Clare conglomerate.

  18. Newtonian nudging for a Richards equation-based distributed hydrological model

    Science.gov (United States)

    Paniconi, Claudio; Marrocu, Marino; Putti, Mario; Verbunt, Mark

    The objective of data assimilation is to provide physically consistent estimates of spatially distributed environmental variables. In this study a relatively simple data assimilation method has been implemented in a relatively complex hydrological model. The data assimilation technique is Newtonian relaxation or nudging, in which model variables are driven towards observations by a forcing term added to the model equations. The forcing term is proportional to the difference between simulation and observation (relaxation component) and contains four-dimensional weighting functions that can incorporate prior knowledge about the spatial and temporal variability and characteristic scales of the state variable(s) being assimilated. The numerical model couples a three-dimensional finite element Richards equation solver for variably saturated porous media and a finite difference diffusion wave approximation based on digital elevation data for surface water dynamics. We describe the implementation of the data assimilation algorithm for the coupled model and report on the numerical and hydrological performance of the resulting assimilation scheme. Nudging is shown to be successful in improving the hydrological simulation results, and it introduces little computational cost, in terms of CPU and other numerical aspects of the model's behavior, in some cases even improving numerical performance compared to model runs without nudging. We also examine the sensitivity of the model to nudging term parameters including the spatio-temporal influence coefficients in the weighting functions. Overall the nudging algorithm is quite flexible, for instance in dealing with concurrent observation datasets, gridded or scattered data, and different state variables, and the implementation presented here can be readily extended to any of these features not already incorporated. Moreover the nudging code and tests can serve as a basis for implementation of more sophisticated data assimilation

Our data indicate south-westwards dispersion of radiocarbon and the highest 14C activity observed so far in the local environment during the 2011 accident....... The abnormally high 14C activity in the late wood of 2011 ring may imply an unknown source of radiocarbon nearby after the accident. The influence of 14C shrank from 30 km during normal reactor operation to 14 km for the accident in the northwest of FDNPP, but remains unclear in the southwest....

    With the acceleration of urbanization in China, most rural areas formed a widespread phenomenon, i.e., destitute village, labor population loss, land abandonment and rural hollowing. And it formed a unique hollow village problem in China finally. The governance of hollow village was the objective need of the development of economic and social development in rural area for Chinese government, and the research on the evaluation method of rural hollowing was the premise and basis of the hollow village governance. In this paper, several evaluation methods were used to evaluate the rural hollowing based on the survey data, land use data, social and economic development data. And these evaluation indexes were the transition of homesteads, the development intensity of rural residential areas, the per capita housing construction area, the residential population proportion in rural area, and the average annual electricity consumption, which can reflect the rural hollowing degree from the land, population, and economy point of view, respectively. After that, spatial analysis method of GIS was used to analyze the evaluation result for each index. Based on spatial raster data generated by Kriging interpolation, we carried out re-classification of all the results. Using the fuzzy clustering method, the rural hollowing degree in Ningxia area was reclassified based on the two spatial scales of county and village. The results showed that the rural hollowing pattern in the Ningxia Hui Autonomous Region had a spatial distribution characteristics that the rural hollowing degree was obvious high in the middle of the study area but was low around the study area. On a county scale, the specific performances of the serious rural hollowing were the higher degree of extensive land use, and the lower level of rural economic development and population transfer concentration. On a village scale, the main performances of the rural hollowing were the rural population loss and idle land. The

    Full Text Available Together you will get there. A graduation article on the Skejby halfway house: a house where delinquents and students live togetherThe Skejby house is unique and produces remarkable results. The recidivism percentage among its’ delinquent inhabitants is over 20% lower than in the halfway houses where only prisoners reside. The aim of Skejby is to ease the transition between imprisonment and reentry in society. The experiment, in which students and prisoners live together, originates from the idea that behavioral transformation is realized most effectively within a socially engaged group. The principal of collective responsibility is dominant in Skejby, resulting in a feeling of belonging to a group among the delinquents. In this group, the students serve as prosocial role models. Consequently, the standards and values that are picked up in prison are reshaped into much needed skills that are required for living a “regular” life in society. In contrast to the reintegration program in Skejby, the Dutch reintegration program mainly consists of one-to-one consultations between the delinquent and the probation officer. The reintegration thus does not take place in a group to which the delinquent can relate, while it is precisely this unique communal feeling of belonging that induces behavioral change in the prisoners. SAMENVATTING Samen kom je er wel. Een afstudeerartikel over het Skejby halfway house: een huis waar delinquenten en studenten onder één dak wonenHet Skejby house is uniek in zijn soort en boekt opmerkelijke resultaten: het recidivepercentage ligt ruim 20% lager dan bij halfway huizen waar alleen delinquenten wonen. Skejby heeft als doel om de overgang tussen gevangenis en samenleving zo klein mogelijk te maken. Het experiment, waarbij studenten en delinquenten samen wonen, komt voort uit het idee dat gedragsverandering het best bewerkstelligt wordt binnen een sociaal verbonden groep.

    This year marks the 20th anniversary of the launch of Journal of Physics: Condensed Matter in 1989. The journal was formed from the merger of Journal of Physics C: Solid State Physics and Journal of Physics F: Metal Physics which had separated in 1971. In the 20 years since its launch, Journal of Physics: Condensed Matter has more than doubled in size, while raising standards. Indeed, Journal of Physics: Condensed Matter has become one of the leading scientific journals for our field. This could not have occurred without great leadership at the top. No one has been more responsible for this growth in both size and quality than our Senior Publisher, Richard Palmer. Richard first started work at IOP in March 1971 as an Editorial Assistant with J. Phys. B After a few months, he transferred to J. Phys.C The following year, the Assistant Editor of J. Phys. C, Malcolm Haines, left suddenly in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of J. Phys. C, before being given the job of Assistant Editor permanently. Since J. Phys. C and J. Phys. F re-merged to form Journal of Physics: Condensed Matter, Richard gradually shed his other journal responsibilities, except for Reports on Progress in Physics, to build up Journal of Physics: Condensed Matter. He has worked closely with four Editors-in-Chief of J. Phys. C and five of Journal of Physics: Condensed Matter. When Richard announced his retirement this past winter, we met it with a great deal of both happiness and sadness. Of course, we are happy that he is going to be allowed to enjoy his retirement, but we remain very sad to lose such a valuable member of our team, especially the one who had provided the heart and soul of the journal over its 20 years. We will be able to rely upon the team which Richard ably trained as

    The March 11, 2011 magnitude 9.0 Tohoku, Japan earthquake produced a tsunami that inundated the Fukushima Dai-ichi nuclear power plant and led to the accidental release of radioactive 131I, 132Te, 134Cs, and 137Cs to the atmosphere. The Japanese Nuclear Safety Commission estimates that 12,000 TBq of 137Cs were released to the atmosphere during the incident, which represents ~14% of the total estimated 137Cs emission from the Chernobyl disaster in April 1986. Measurements of airborne radiation collected at the Fukushima plant illustrate that >50% of the total emitted radiation was released on March 15 and 16 associated with explosions and fires at reactor units 1, 2, and 4, and 70% was emitted in the first 5 days of the event. The source of the radiation is thus well constrained in time and space, providing an opportunity to better understand long-range atmospheric transport processes from Asia to the Arctic, while also assessing the magnitude of the fallout in the Arctic. Here we describe the 137Cs and 134Cs fallout flux near Thule, Greenland (1700 m a.s.l.), at Summit (3200 m a.s.l.), Greenland, and within Denali National Park, Alaska (2400-3900 m a.s.l.) based on series of large-volume (5-15 l) snow pit samples collected in June and July, 2011. In addition to assessing the spatial variability of Fukushima fallout in the Arctic, the elevation range of samples allows for an analysis of any vertical heterogeneity in fallout transport and deposition. Major ion concentrations and stable water isotope ratios are used to confirm the seasonal timing of the Fukushima fallout horizon in the snowpack. Radiocesium was concentrated and isolated from the snow pit meltwater using the well-established ammonium phosphomolybdate (AMP) adsorption method, and 134Cs and 137Cs concentrations were measured using gamma spectrometry with a Canberra 3523 well-type intrinsic Ge-detector at the Dartmouth College Short-Lived Isotope Laboratory.

    Full Text Available In this work we study the problem of modeling identification of a population employing a discrete dynamic model based on the Richards growth model. The population is subjected to interventions due to consumption, such as hunting or farming animals. The model identification allows us to estimate the probability or the average time for a population number to reach a certain level. The parameter inference for these models are obtained with the use of the likelihood profile technique as developed in this paper. The identification method here developed can be applied to evaluate the productivity of animal husbandry or to evaluate the risk of extinction of autochthon populations. It is applied to data of the Brazilian beef cattle herd population, and the the population number to reach a certain goal level is investigated.Neste trabalho estudamos o problema de identificação do modelo de uma população utilizando um modelo dinâmico discreto baseado no modelo de crescimento de Richards. A população é submetida a intervenções devido ao consumo, como no caso de caça ou na criação de animais. A identificação do modelo permite-nos estimar a probabilidade ou o tempo médio de ocorrência para que se atinja um certo número populacional. A inferência paramétrica dos modelos é obtida através da técnica de perfil de máxima verossimilhança como desenvolvida neste trabalho. O método de identificação desenvolvido pode ser aplicado para avaliar a produtividade de criação animal ou o risco de extinção de uma população autóctone. Ele foi aplicado aos dados da população global de gado de corte bovino brasileiro, e é utilizado na investigação de a população atingir um certo número desejado de cabeças.

  13. Who invented the dichotomous key? Richard Waller's watercolors of the herbs of Britain.

    2011-12-01

    On 27 March 1689, Richard Waller, Fellow and Secretary of the Royal Society presented his "Tables of the English Herbs reduced to such an order, as to find the name of them by their external figures and shapes" to his assembled colleagues at a meeting of the Royal Society. These tables were developed for the novice by being color images, composed in pencil and watercolor, of selected plants and their distinguishing characteristics. The botanical watercolors for the tables are now a Turning-the-Pages document online on the website of the Royal Society. However, for the past 320 years, the scientific context for the creation of these outstanding botanical watercolors has remained obscure. These tables were developed by Waller as an image-based dichotomous key, pre-dating by almost 100 years the text-based dichotomous keys in the first edition of Flora Française (1778) by Jean Baptiste Lamarck, who is generally given priority for the development of the dichotomous key. How these large folio images were arranged to illustrate a dichotomous key is unknown, but an arrangement based on Waller's description is illustrated here as leaf-ordering for the separate hierarchical clusters (tables). Although only 24 species of watercolored dicot herbs out of a total of 65 in the set of watercolors (the others being monocots) are used in these tables, they are a "proof of concept", serving as models upon which a method is based, that of using a key composed of dichotomous choices for aiding identification.

    2011-12-01

    Full Text Available This essay contextualizes the work of war correspondent Richard Harding Davis within an evolving “imperial news apparatus” that would culminate in his reporting of the Spanish-American War. Critics have conventionally framed Davis squarely within the imperial cause, associating him with his admirer Roosevelt and naval admiral Alfred T. Mahan. Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  17. Against the Nihilism of Suffering and Death: Richard E. K. Kim and His Works

    Directory of Open Access Journals (Sweden)

    Jooyeon Rhee

    2016-03-01

    Full Text Available This article examines the life and works of Richard E. K. Kim (1932–2009, a first-generation Korean diasporic writer in the United States. It focuses on how Kim struggled to overcome the nihilism of suffering and death that derived from colonialism and the Korean War through his literary works. Kim witnessed firsthand these two major historical events, which caused irrevocable psychological and physical damage to many people of his generation. In his autobiographical fiction, he conveys painful memories of the events by reviving the voices of people in that era. What his works offer us goes beyond vivid memories of the past, however; they also present the power of forgiveness as a condition to overcome the nihilism of suffering and death. Remembrance and forgiveness are, therefore, two major thematic pillars of his works that enable us to connect to these difficult and traumatic times. These themes are portrayed in such a gripping way mainly because Kim tried to maintain a certain distance—an emotional and linguistic distance—from the familiar, in order to elucidate the reality of the human condition: an ontological position of the exile from which he produced his works. This article argues that Kim’s works provide us the possibility to transcend the nihilism of historical trauma through articulating the meaning of remembrance and forgiveness from his self-assumed position of exile.

  18. Providing the physical basis of SCS curve number method and its proportionality relationship from Richards' equation

    Hooshyar, M.; Wang, D.

    2016-12-01

    The empirical proportionality relationship, which indicates that the ratio of cumulative surface runoff and infiltration to their corresponding potentials are equal, is the basis of the extensively used Soil Conservation Service Curve Number (SCS-CN) method. The objective of this paper is to provide the physical basis of the SCS-CN method and its proportionality hypothesis from the infiltration excess runoff generation perspective. To achieve this purpose, an analytical solution of Richards' equation is derived for ponded infiltration in shallow water table environment under the following boundary conditions: 1) the soil is saturated at the land surface; and 2) there is a no-flux boundary which moves downward. The solution is established based on the assumptions of negligible gravitational effect, constant soil water diffusivity, and hydrostatic soil moisture profile between the no-flux boundary and water table. Based on the derived analytical solution, the proportionality hypothesis is a reasonable approximation for rainfall partitioning at the early stage of ponded infiltration in areas with a shallow water table for coarse textured soils.

  19. Unreliability and the Animal Narrator in Richard Adams’s The Plague Dogs

    Directory of Open Access Journals (Sweden)

    Anja Höing

    2017-03-01

    Full Text Available Richard Adams’s talking animal story The Plague Dogs (1978, with its deeply genre-atypical mode of narration, offers a multiplicity of avenues to explore the literary animal as animal. The story draws much of its power from the psychological complexity and related unreliability of both canine narrators, two research lab escapees gone feral. Both the terrier Snitter and the black mongrel Rowf are mentally ill and experience a highly subjective, part-fantastic world. In episodes of zero focalization, a sarcastic voice comments on the plot from the off, aggressively attacking a thoroughly anthropocentric superstructure the protagonists themselves are oblivious of, and presenting all that is normally constructed as “rational” in the implied reader’s world as a carnivalesque farce. Combining these equally unreliable narratives, The Plague Dogs creates a unique mixture of what Phelan (2007 calls “estranging” and “bonding” unreliability and brings to light the devastating consequences of anthropocentrism. The Plague Dogs not only defamiliarizes a genre usually committed to conventional means of storytelling, but the dominant Western conception of the status of animals in the world, showing that once we start to read the animal as animal, this sets into motion an avalanche of other concepts in need of re-reading, among them the very ones making up the fundamental pillars of Western societies’ anthropocentric self-conception.

Questions on ethics are not merely questions on the responsibility of one or two specific individuals, but rather as what have been defined accurately by Immanuel Kant in Critique of Practical Reason – as question of all humanity as a thinking creature and the freedom of choice on, “what should I do”. From Kant’s definition, we may infer that if human can not think and not free in determining their choice, it would be almost impossible to hope for moral responsibility. However this article does not mean to give a full and historical description on ethics, but a sketch on discourse of contemporary ethics which is represented by two famous philosophers, Jürgen Habermas from the tradition of  Critical Theory from Frankfurt School, dan Richard Rorty with “Neo-Pragmatism”. Habermas proposes “discourse ethics” while Rorty proposes ethic concepts through his “liberal-ironists”. It is hoped that the assembly of readers may gain an insight of the unavoidable ethics problems since every ethical position must be theory laden and the theory itself has historical characteristics (the characteristics, origin and historical context of the schools behind it. Therefore ethics is a neverending reflection although it has been started from 2500 years ago. Ethics invites us from specific sciences to enter its general discourse which unavoidably all-encompassing in its nature. 

  1. Richard Rorty:From Anti-metaphysical Neo-Pragmatism to Rejection of Philosophy

    Full Text Available Richard Rorty is a neo-Pragmatist philosopher. For three decades, he has attacked the traditional philosophy (from Plato to Kant as well as any other epistemology searching for truth or claiming to mirror the nature in his philosophical works. Rorty holds that, according to the history of philosophy in his reading, there is no final answer to the traditional questions concerning knowledge, truth, and representation. These questions, therefore, should be dissolved and denied. He maintains that knowledge is justified belief, justification, however, being not the consequence of some correspondence between the theory or the statement, but the consequence of conversation, social practice, group consensus, and social solidarity. Rorty also thinks that democracy has priority on philosophy, disagreeing with the thesis that philosophy is the foundation of the rest of culture.Despite of usefulness of some elements and implications of Rorty’s metaphilosophy (such as his emphasis on freedom, democracy, and pluralism as well as his insisting on philosophical humility and avoiding scientific pride, it is faced with several problems, including 1 ignoring the referential and realist features of language, 2 confusing interpretation and reality, 3 eliminating the border between objectivity and subjectivity, 4 interfering of public and private life, and 5 ignoring the need of science, culture, technology and, in particular, politics, in philosophy. The authors try to show and analyze some elements of these problems.

  2. Has David Howden Vindicated Richard von Mises’s Definition of Probability?

    Full Text Available In my recent article on these pages (Crovelli 2009 I argued that members of the Austrian School of economics have adopted and defended a faulty definition of probability. I argued that the definition of probability necessarily depends upon the nature of the world in which we live. I claimed that if the nature of the world is such that every event and phenomenon which occurs has a cause of some sort, then probability must be defined subjectively; that is, “as a measure of our uncertainty about the likelihood of occurrence of some event or phenomenon, based upon evidence that need not derive solely from past frequencies of ‘collectives’ or ‘classes.’” I further claimed that the nature of the world is indeed such that all events and phenomena have prior causes, and that this fact compels us to adopt a subjective definition of probability.David Howden has recently published what he claims is a refutation of my argument in his article “Single Trial Probability Applications: Can Subjectivity Evade Frequency Limitations” (Howden 2009. Unfortunately, Mr. Howden appears to not have understood my argument, and his purported refutation of my subjective definition consequently amounts to nothing more than a concatenation of confused and fallacious ideas that are completely irrelevant to my argument. David Howden has thus failed in his attempt to vindicate Richard von Mises’s definition of probability.

    Long before his last book, The Gift Relationship: From Human Blood to Social Policy, was published in early 1971, Richard M. Titmuss (1907-1973), a professor of social administration at the London School of Economics, had been a major figure in the debates over the welfare state. The Gift Relationship was the culmination of an eventful relationship with the Institute of Economic Affairs, a think tank that advocated the extension of rational pricing to social services. By arguing that the British system of blood procurement and distribution, based on free giving within the National Health Service, was more efficient than the partly commercialized American system, Titmuss intended to signal the dangers of the increasing commercialization of society. What made for the impact of his book, however, was not merely its argument that transfusion-transmitted infections were much more common with paid than with voluntary donors, but also its reflections on what it is that holds a society together. And here Titmuss argued that a "socialist" social policy, by encouraging the sense of community, played a central role. The eclecticism of Titmuss's work, together with its strong ethical and political flavor, makes it a rich and original account of the "social" at a time when heated debated over social policy, both in Britain and in the United States, raised the question of the division of labor among the social sciences.

    Full Text Available Albania, as well as a great part of the Balkan area in general, still suffers a lack of environmental studies especially in limnological research. The Dumre plateau, in Central Albania, is characterized by an extraordinary high number of karst lakes in a small geographic area. Despite their environmental peculiarity, very few biological data are to date available for these lakes, none on the zooplankton. For this reason, 15 water bodies located in the central area of the plateau were selected for a preliminary limnological survey carried out in the years 2008-2011. Neodiaptomus schmackeri (Poppe & Richard, 1892, a diaptomid calanoid copepod characterized by a South-Eastern Palearctic - Oriental distribution, and the most widely spread Neodiaptomus species in Asia, was found in 8 lakes of the Dumre area. This finding represents the first record of the species, and of the entire genus Neodiaptomus, for Europe. Several environmental variables were measured to characterize the lakes, and the co-occurring planktonic crustaceans were also identified. Taxonomical drawings and descriptions of the main morphological features of both sexes are herein provided in order to compare the Albanian populations of N. schmackeri with those of the native distribution area of the species. The possible causes which determined the occurrence of this non-indigenous species in several Dumre lakes are discussed.

    Full Text Available This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite and analyzed for 238U, 234U, 226Ra, 210Pb, 235U, 232Th, 228Ra, 228Th and 40K using delayed neutron activation analysis and low energy gamma spectroscopy. Rutile was found to be the most radioactive mineral ore within the facility with 210Pb concentration of 759.00 ± 106.00 Bq·kg−1. Effective annual dose rate in (mSv·y−1 delivered to different organs of the body: testes, bone marrow, whole body, lungs and ovaries from mineral ores were such that dose from mineral ores decreased in the order coal > rutile > rock phosphate > hematite > zircon. The organs with the highest received dose rate were the testes and this received dose was from coal. However, all of the calculated absorbed dose rates to organs of the body were below the maximum permissible safety limits.

  6. “This World Is Not My Home”: Richard Mouw and Christian Nationalism

    Full Text Available American evangelicalism has often been punctuated by dual commitments to the United States and to God. Those commitments were strongest within politically conservative evangelicalism. Though representing a solid majority among professing evangelicals, conservatives could not speak for the movement as a whole. Politically progressive evangelicals, beginning in the 1960s, formed a dissenting opinion of the post-World War II revival of Christian nationalism. They dared to challenge American action abroad, noticeably during the Vietnam War. Their critique of Christian nationalism and conservative evangelicals’ close ties to the Republican Party led them to seek refuge in either progressive policies or the Democratic Party. A third, underexplored subgroup of evangelicalism rooted in reformed theology becomes important to consider in this regard. These reformed evangelicals sought to contextualize nationalism in biblical rather than partisan or political terms. This goal is championed well by Richard Mouw, resulting in a nuanced look at evangelical Christians’ difficult dual role as both citizens of the Kingdom of God and the United States.

  7. Poets/Trump/Philosophers: Reflections on Richard Rorty’s Liberalism, Ten Years after His Death

    2017-08-01

    Full Text Available Starting with a prescient 1998 quote on the impending decline of US liberal democracy into right-wing, strong-man-based demagogy, this paper outlines Richard Rorty’s political philosophy, which I believe can help us understand perplexing political trends in today’s political reality well beyond the US alone. Specifically, I tackle three key-terms encapsulating the thrust of Rorty’s political philosophy, i.e. “liberalism of fear”, “bourgeois” and “postmodernism”. Also, I address a contraposition that explains how Rorty would approach and attempt to defend liberal democracy from contemporary right-wing, strong-man-based degenerations, namely the priority of “poetry” over “philosophy”. Essentially, if one wishes to win in the political arena, she must be armed with the most effective rhetorical weaponry, however good, solid and well-argued her political views may be. Finally, some remarks are offered on the role that “philosophy” can still play within the same arena.

  8. Arctic observers: Richard King, monogenism and the historicisation of Inuit through travel narratives.

    In 1848 the ethnologist, surgeon and Arctic explorer Richard King (1810-1876) published a three-part series on Inuit in the Journal of the Ethnological Society of London. This series provided a detailed history of Inuit from the eleventh century to the early nineteenth century. It incorporated a mixture of King's personal observations from his experience travelling to the Arctic as a member of George Back's expedition (1833-1835), and the testimonies of other contemporary and historical actors who had written on the subject. The aim was to historicise Inuit through the use of travel reports and show persistent features among the race. King was a monogenist and his sensitive recasting of Inuit was influenced by his participation in a research community actively engaged in humanitarian and abolitionist causes. The physician and ethnologist Thomas Hodgkin (1798-1866) argued that King's research on Inuit was one of the best ethnological approaches to emulate and that it set the standard for the nascent discipline. If we are to take seriously Hodgkin's claim, we should look at how King constructed his depiction of Inuit. There is much to be gained by investigating the practices of nineteenth-century ethnologists because it strengthens our knowledge of the discipline's past and shows how modern understandings of races were formed.

    2017-04-01

    In the early stage of the Fukushima Dai-ichi Nuclear Power Station (F1NPS) accident, number of spot type contamination has been observed in computed autoradiography (Kashimura 2013, Shibata 2013, Satou 2014). It's means presence of radioactive particles, however, insoluble cesium particle was overlooked because cesium, which is dominant radioactive element in the accident, becomes ionized in the environment. Adachi et al. (2013) showed presence of cesium (Cs)-bearing particles within air dust sample collected at Tsukuba, 170 km south from the Fukushima site, in midnight of 14 to morning of 15 March 2011. These particles were micrometer order small particles and Cs was could be detectable as element using an energy dispersive X-ray spectroscopy (EDX). However, other radioactive elements such as Co-60, Ru-103 and uranium, which were dominant element of radioactive particles delivered from Chernobyl accident, could not detected. Abe et al. (2014) employed a synchrotron radiation (SR)-micro(μ)-X-ray analysis to the Cs-bearing particles, and they were concluded that (1) contained elements derived from nuclear fission processes and from nuclear reactor and fuel materials; (2) were amorphous; (3) were highly oxidized; and (4) consisted of glassy spherules formed from a molten mixture of nuclear fuel and reactor material. In addition, Satou et al. (2016) and Yamaguchi et al. (2016) disclosed that silicate is main component of Cs-bearing particles. Satou et al. (2015) discovered two types of radioactive particles from soil samples collected in the vicinity of the F1NPS. These particles were remained in the natural environment more than four years, silicate is main component in common of each group particles. Group A particles were very similar to Cs-bearing particles reported by Adachi et al. except particle shape. On the other hand, group B is big particles found in north area from the F1NPS, and the strongest particles contained 20 kBq of Cs-137 within a particle

    In March 2011, the Fukushima Dai-ichi reactor power plant was crippled by the Great Pacific earthquake and subsequent tsunami. Much of the focus in the news was on the reactor site itself as the utility company (TEPCO), the Japanese government, and experts from around the world worked to bring the damaged plants into a safe shutdown condition and stem the release of radioactivity to the environment. Most of the radioactivity released was carried out to sea with the prevailing winds. Still, as weather patterns changed and winds shifted, a significant plume of radioactive materials released from the plant deposited in the environment surrounding the plant, contaminating large land areas of the Fukushima Prefecture. The magnitude of the radiological impact to the surrounding environmental is so large that the Japanese government has had to reevaluate the meaning of 'acceptably clean'. In many respects, 'acceptably clean' cannot be a one-size-fits-all standard. The economics costs of such an approach would make impossible what is already an enormous and costly environmental response and remediation task. Thus, the Japanese government has embarked upon an approach that is both situation-specific and reasonably achievable. For example, the determination of acceptably clean for a nursery school or kindergarten play yard may be different from that for a parking lot. The acceptably clean level of residual radioactivity in the surface soil of a rice paddy is different from that in a forested area. The recognized exposure situation (scenario) thus plays a large role in the decision process. While sometimes complicated to grasp or implement, such an approach does prioritize national resources to address environment remediation based upon immediate and significant risks. In addition, the Japanese government is testing means and methods, including advanced or promising technologies, that could be proven to be effective in reducing the amount of radioactivity

    Dai-Kenchu-To (DKT) is a herbal medicine and is currently used as the treatment of paralytic ileus in Japan. We investigated the mechanism of beneficial effects of DKT in vitro. DKT-extract powder (DKT-EP; 30-300 microg/ml) caused a significant inhibition on carbachol (CCH: 10(-6))-induced contraction in a concentration dependent manner of the rat distal colon. DKT-EP (100 microg/ml) consists of 20 microg/ml of Zanthoxylum Fruit, 30 microg/ml of Ginseng Root and 50 microg/ml of Ginger Rhizome. Although each of them had no effect on CCH-induced muscle contraction, the combination of three ingredients caused a significant inhibition on CCH-induced contraction.

    The severe accident that broke out at Fukushima Dai-ichi nuclear power stations on March 11, 2011, caused seemingly infinite damage to the daily life of residents. Serious and wide-spread contamination of the environment occurred due to radioactive materials discharged from nuclear power stations (NPSs). At the same time, many issues were highlighted concerning countermeasures to severe nuclear accidents. The accident is outlined, and lessons learned are extracted with respect to the safety of NPSs, as well as radiation protection of residents under the emergency involving the accident. The materials of the current paper are those released by governmental agencies, academic societies, interim reports of committees under the government, and others. PMID:23138450

    2012-07-01

    In the wake of the March 11 earthquake and tsunami and the subsequent flooding of several of the Fukushima Dai-Ichi reactors, Japan and the Japanese utility TEPCO faced a crisis situation with incredible challenges: substantial amounts of radioactive mixed seawater and freshwater accumulated in the basements of four reactor and other buildings on the site. This water held varying levels of contamination due to the fact that it had been in contact with damaged fuel elements in the cores and with other contaminated components. The overall water inventory was estimated at around 110,000 tons of water with contamination levels up to the order of 1 Ci/l. Time was of the essence to avoid overflow of this accumulated water into the ocean. AREVA proposed, designed and implemented a water treatment solution using a proven chemical coprecipitation process with ppFeNi reagent, which is currently in use for effluent treatment on several nuclear sites including AREVA sites. In addition to the extremely short schedule the other challenge was to adapt the chemical treatment process to the expected composition of the Fukushima water and, in particular, to evaluate the impact of salinity on process performance. It was also necessary to define operating conditions for the VEOLIA equipment that had been selected for implementation of the process in the future facility. The operation phase began on June 17, and by the end of July more than 30,000 tons of highly radioactive saltwater had been decontaminated - the Decontamination Factor (DF) for Cesium was ∼10{sup 4}. It allowed recycling the contaminated water to cool the reactors while protecting workers and the environment. This paper focuses on the Actiflo{sup TM}-Rad water treatment unit project that was part of the TEPCO general water treatment scheme. It presents a detailed look at the principles of the Actiflo{sup TM}-Rad, related on-the-fly R and D, an explanation of system implementation challenges, and a brief summary of

    Full Text Available This study focuses on three recent literary works (fiction and non-fiction novels written by authors of Asiatic origins: the French-speaking Chinese writer, Dai Sijie, the Iranian professor, Azar Nafisi, and the Japanese writer, Murakami Haruki. In the titles of these international bestsellers (Balzac and the Little Chinese Seamstress, Reading Lolita in Tehran, and Kafka on the Shore, we find an oxymoron: the name of a famous, canonical Western writer or character is used in an unusual context, linked to the geography of the near or far East. The consequent effect of estrangement can restore strength to literature, perhaps with greater determination than is possible in Western cultures. By using (and reversing the coordinates of Edward Said’s idea of Orientalism and, as in Kafka on the Shore, certain concepts of the Lacanian theory, this study analyzes the transfer of the European literary myths towards Eastern cultures.

  20. Sufi, Christian or Buddhist? Richard Francis Burton’s “Parameters of Belief”

    Directory of Open Access Journals (Sweden)

    John Wallen

    2013-09-01

    Full Text Available Richard Burton has been interpreted and misinterpreted by literary critics as eminent as Edward Said and Louisa Pratt as well as by others such as Rana Kabbani and Reina Lewis. Biographers like Fawn Brody, Edward Rice, Mary Lovell and Jon Godsall have also had their say. Burton has been variously described as imperialist, sexist, gay, obssessed with pornography, racist, plagiarist, sexual libertine, scatologist, expert sociologist, profoundly deceitful and impotent. In spite of this negative press, interest in Burton is always high as his life and times are relevant to many scholars interested in the 19th century origins of modern thought and postcolonial ideas. In this paper presentation I will attempt to get beyond the confused and contradictory portrayals of Burton over the last 50 or so years by looking in some detail at Burton’s two long poems: Stone Talk and The Kasidah. In these works, published 15 years apart, Burton writes under pseudonyms and, as I will argue, is able to express many of his deepest beliefs, especially in The Kasidah where he is playing the part of Hadji Abu Al Yezid, a Sufi like-wise man who possesses some startling similarities to Burton himself. What emerges from this close examination of the texts is a sensitive relativist who, while adhering to the scientific method in all his practical dealings, is yet able to consider the possibility that everything we see around us and all our experience of the world might be, finally, nothing more than Maya and illusion.

    2016-09-01

    Full Text Available The Holocaust will always be remembered as one of the most horrific and evil events in all of history. One question that has been so pervasive in regards to this historical event is the question of why. Why exactly did Hitler massacre the Jewish people? Why did he come to the conclusion that the Jews were somehow lesser than him, and that it was okay to kill them? What and who were his influences and how did they help form Hitler’s opinions leading up to the Holocaust? Although more than one situation or person influenced Hitler, I believe that one man in particular really helped contribute to Hitler’s ideas, especially about the Jewish people. This man is the famous musician Richard Wagner. While musicologists admit that Wagner was a musical genius, one aspect of his career that is hard to ignore is his strong antisemitism. In addition to speaking about his hatred for the Jews, he also wrote about it in his music, making it hard to glance over. Hitler had been close to the Wagner family, and had an obsessive, cult-like infatuation with Wagner’s music beginning in his childhood. This infatuation with Wagner’s music and his closeness to his later family helped facilitate and solidify his negative views about the Jewish people. In this paper I will explore the antisemitism that is within Wagner’s music and writing, and then I will discuss how Wagner’s antisemitism helped inform, influence, and shape Hitler’s ideas, indirectly assisting in the propagation of the Holocaust.

    Full Text Available Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory and proprioceptive inputs. Richard Serra’s Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesised to have stimulated the body’s vertical and longitudinal axes as it showcased 5 monumental rectangular solids pitched at a 1.69° angle.Using computerised dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements before and after walking around and alongside the sculpture (i.e., before and after a promenade. A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway. Eye movement exploration in the depth of the sculpture increased antero-posterior stability (in terms of spectral power and cancelling time of body sway at the expense of medio-lateral stability (in terms of cancelling time. Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto was cancelled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power increased after the promenade.Fourteen additional visitors were asked to sit in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra’s monumental statuary works resulted in significantly improved performances on the subjective visual vertical test.We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic training ground thereby improving the visitors’ overall sense of visual perspective, equilibrium and gravity.

Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  4. Charles Darwin, Richard Owen, and Natural Selection: A Question of Priority.

    No single author presented Darwin with a more difficult question about his priority in discovering natural selection than the British comparative anatomist and paleontologist Richard Owen. Owen was arguably the most influential biologist in Great Britain in Darwin's time. Darwin wanted his approbation for what he believed to be his own theory of natural selection. Unfortunately for Darwin, when Owen first commented in publication about Darwin's theory of descent he was openly hostile (Edinb. Rev. vol. 111, Article VIII, 1860, pp. 487-533, anonymous). Darwin was taken off-guard. In private meetings and correspondence prior to 1860 Owen had been nothing but polite and friendly, even helping Darwin in cataloguing and analyzing Darwin's zoological specimens from the Beagle voyage. Every early indication predicted a life-long friendship and collaboration. But that was not to be. Owen followed his slashing review with a mounting campaign in the 1860s to denounce and discredit both Darwin and his small but ascendant circle of friends and supporters. But that was not enough for Owen. Starting in 1866, perhaps by now realizing Darwin had landed the big fish, Owen launched a new campaign, to claim the discovery of "Darwin's theory" for himself. Darwin naturally fought back, mainly in the "Historical Sketch" that he prefaced to Origin starting in 1861. But when we peel back the layers of personal animus and escalating vituperation we discover in fact their quarrel was generated more by mutual misunderstanding than scientific disagreement. The battle ended only when Darwin finally penetrated to the crux of the matter and put an end to the rivalry in 1872, in the final version of the Sketch.

  5. Morrow, Reiff, Receive 2013 Space Physics and Aeronomy Richard Carrington Awards: Response

    It is a special privilege to receive this award honoring Richard Carrington's discovery of what we now call space weather. It is particularly appropriate that this award also recognizes Cherilynn Morrow, who 20 years ago made a presentation to the Space Science Advisory Committee on Jeff Rosendhal's idea of mission-based E/PO. We worked together, bringing that idea to the successful, but threatened, network it is today. For me, learning and teaching go hand in hand—as we publish our findings for our peers, we should also repay the public investment in our research with accurate, understandable results. My interest in space science was sparked by a father-daughter course in astronomy sponsored by the Brownies at the Oklahoma City Planetarium and kindled by the Bell Labs production The Strange Case of the Cosmic Rays directed by Frank Capra. Knowing that planetarium shows and educational movies can change lives, I have devoted a large portion of my last 25 years to creating software, shows, and portable planetariums to inspire and engage youth. This has not been a one-person effort, of course. My work Cherilynn Ann Morrow would have been impossible without the collaboration of Carolyn Sumners, vice president of the Houston Museum of Natural Science. Our museum kiosk and planetarium control software would not have happened without the skill and perseverance of my chief programmer, Colin Law. Jim Burch has been first a mentor and then a colleague on both the research and outreach sides of my career. I share this honor with a long line of highly talented students and postdocs who have contributed science content and outreach efforts. Most importantly, without the support of my husband, Tom Hill, I would not have had the time and freedom to build an educational network while continuing research and raising a family. I thank AGU for bestowing this honor.

    The assessment of sleep quality in critically ill patients is a relevant factor of high-quality care. Despite the fact that sleep disturbances and insufficient sleep management contain an increased risk of severe morbidity for these patients, a translated and applicable instrument to evaluate sleep is not available for German-speaking intensive care settings. This study aimed to translate the Richards Campbell Sleep Questionnaire (RCSQ), a simple and validated instrument eligible for measuring sleep quality in critically ill patients, and subsequently to evaluate the internal consistency of the German version of the RCSQ. Furthermore, it also aimed to inquire into the perception of sleep in a sample of critically ill patients. The RCSQ was translated following established methodological standards. Data were collected cross-sectionally in a sample of 51 patients at 3 intensive care units at a university hospital in Germany. The German version of the RCSQ showed an overall internal consistency (Cronbach's alpha) of 0·88. The mean of the RSCQ in the sample was 47·00 (SD ± 27·57). Depth of sleep was rated the lowest and falling asleep again the highest of the RCSQ sleep items. The study demonstrated very good internal consistency of the German version of the RCSQ, allowing for its application in practice and research in German-speaking countries. Quality of sleep perception was generally low in this sample, emphasizing the need for enhanced care concepts regarding the sleep management of critically ill patients. Relevance to clinical practice Assessment of self-perception of sleep is crucial in order to plan an individually tailored care process. © 2017 British Association of Critical Care Nurses.

  7. An Enlightenment proposal for music therapy: Richard Brocklesby on music, spirit, and the passions.

    2015-01-01

    In 1749, the London physician Richard Brocklesby (1722-1797) published his Reflections on Antient [sic] and Modern Musick, an essay that not only sought to compare these practices in terms of their effects, but also to gather evidence supporting the use of music in treating mania and other mental diseases. As might be expected, Brocklesby's discussion of music therapy has already received attention by authors looking back to the origins of this practice, not least because he offers an account of a successful musical cure that took place in his own time (Rorke, 2001). My chapter, however, seeks to broaden the discussion of the Reflections, in order to show how Brocklesby's projected musical cures fit into his larger worldview, one that was influenced as much by Plato and other ancient philosophers as it was by modern thinkers such as Isaac Newton and his followers. Brocklesby's argument was essentially that music acted as a link between the mind and body and therefore could restore their intrinsic harmony, a connection that was mediated by the animal spirits, which also served as the vehicle of the passions. The movements and proportions of music could arouse or quell the passions by their effect on these (imaginary) spirits, which flowed through the nerves and brain and acted as the agent for the mind or soul. I show how his account of music in antiquity led him to reflect on the way that music was perceived and responded to in his own time, both as a stimulus to mental and bodily action, and as a source of esthetic pleasure through the cultivation of musical taste. © 2015 Elsevier B.V.

  8. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  9. Timothy Leary, Richard Alpert (Ram Dass) and the changing definition of psilocybin.

    2010-05-01

    This research focuses on the events leading to the 1968 U.S. federal prohibition of psilocybin. It is a study of duelling moral entrepreneurs-Timothy Leary and Richard Alpert vs. the Harvard University Administration. The goal is to show how the primary active compound in an ostensibly harmless fungus (the psilocybin mushroom) became controversial in less than a decade. We used books, newspapers, magazine articles and previously unpublished materials (including documents from the Harvard Archives) to analyze Leary and Alpert's lives and careers through the early 1970s. The prohibition of psilocybin in the U.S. was largely a product of Leary and Alpert's involvement in the "Harvard drug scandal" and their transformation from Harvard professors to countercultural icons. They tested the substance on a variety of human subjects and in doing so piqued the interest of Harvard undergraduates while drawing condemnation from other faculty and Harvard administrators. This case is theoretically interesting because unlike most illegal drugs, psilocybin was never linked to a threatening minority group, but to some of the nation's most privileged youth. The Harvard administrators were not really moral entrepreneurs but Leary and Alpert clearly were. Although they were far from being prohibitionists, they were self-righteous crusaders on different but equally holy missions for the good of young and minority Americans. Ironically, due to their successes the possession of psilocybin was criminalized under United States federal law in 1968 (Pub. L. No. 90-639, Stat. 1361 1968 and Boire, 2002). This case study demonstrates that crusaders can be successful in changing culture even when laws are passed in futile attempts to control their behaviour, just as Leary predicted.

  10. Richard Doll and Alice Stewart: reputation and the shaping of scientific "truth".

    2011-01-01

    As the world watched the Fukushima reactors release radionuclides into the ocean and atmosphere, the warnings of Dr. Alice Stewart about radiation risk and the reassurances of Sir Richard Doll assumed renewed relevance. Doll and Stewart, pioneer cancer epidemiologists who made major contributions in the 1950s-he by demonstrating the link between lung cancer and smoking, she by discovering that fetal X-rays double the chance of a childhood cancer-were locked into opposition about low-dose radiation risk. When she went public with the discovery that radiation at a fraction of the dose "known" to be dangerous could kill a child, her reputation plummeted, whereas Doll, foremost among her detractors, was knighted and lauded as "the world's most distinguished medical epidemiologist" for his work. Their lives and careers, so closely intertwined, took contrary courses, he becoming "more of the establishment" (as he said), while she became more oppositional. When it was discovered, after his death, that he'd been taking large sums of money from industries whose chemicals he was clearing of cancer risk, his reputation remained unscathed; it is now enshrined in the "Authorized Biography" (2009) commissioned by the Wellcome Institute, along with Doll's denigration of Stewart as an "embittered" woman and biased scientist. Stewart lived long enough to see radiation science move her way, to see international committees affirm, in the 1990s, that there is no threshold beneath which radiation ceases to be dangerous; recent evidence from Chernobyl is bearing out her warnings. But a look at the making and breaking of these reputations reveals the power of status, position, and image to shape scientific "knowledge" and social policy.

    Sinusoidal obstruction syndrome (SOS) is drug-induced liver injury that occurs in patients who receive hematopoietic cell transplantation and oxaliplatin-contained chemotherapy. The aim of study was to investigate the pharmacological treatment of SOS using a traditional Japanese medicine, Dai-kenchu-to (DKT). Male Sprague-Dawley rats were treated with monocrotaline (MCT) to induce SOS. The rats were divided into three groups: control, MCT and MCT+DKT groups. In the MCT+DKT group, DKT was gavaged at 12 h after MCT treatment and given every 12 h until the end of the protocol. The rats of MCT group were treated with water instead of DKT. At 48 h after MCT treatment, blood and liver samples were collected. In the MCT+DKT group, the macroscopic and histological findings revealed liver congestion, sinusoidal alteration and the destruction of sinusoidal lining, which were comparable with those of the MCT group. However, the area of hepatic necrosis and serum AST levels significantly decreased in the MCT+DKT group compared with those of the MCT group. Treatment with DKT resulted in the reduction of neutrophil accumulation, myeloperoxidase activity and the expression of cytokine-induced neutrophil chemoattractant (CINC) and intracellular adhesion molecule-1 (ICAM-1) mRNA in the liver compared with those of the MCT group. Treatment with processed ginger, one of the ingredients in DKT, resulted in similar effects to those shown by DKT. Dai-kenchu-to attenuates MCT-induced liver injury by preventing neutrophil-induced liver injury through blockage of upregulation of CINC and ICAM-1 mRNA level.

    The Fukushima nuclear plant accident has been examined aiming at clarifying the factors influencing responding which is one of the four cornerstones of resilience engineering. Among the causal factors of responding, such as attitude, skill, health and environment, particular attention has been paid on the role of attitude. In addition, the case of Tokai Dai-ni nuclear plant, which was the success case despite tsunami attack, and the case of Fukushima Dai-ichi nuclear plant have been examined focusing on preparatory actions taken prior to the tsunami attack. Through the comparative examinations, attitudes of several kinds have been identified as key factors contributing to enhance organizational resilience. Moreover, the importance of safety-II concept proposed in conjunction with the methodology of resilience engineering has been clearly exemplified. As a whole, it can be concluded that the methodology of resilience engineering and the concept of safety-II are quite effective when utilized with the structured model. (author)

    AESJ Nuclear Safety Division published 'Report on the Fukushima Dai-ichi Accident Seminar - what was wrong and what should been down in future-' which would be published as five special articles of the AESJ journal. The Fukushima Dai-ichi accident identified issues of several activities directly related with nuclear safety in the areas of safety design, severe accident management and safety regulations. PRA, operational experiences and safety research could not always contribute safety assurance of nuclear power plant so much. This article (4) summarized technical issues based on related facts of the accident as much as possible and discussed' what was wrong and what should be down in future'. Important issues were identified from defense-in-depth philosophy and lessons learned on safety design were obtained from accident progression analysis. Activities against external events and continuous improvements of safety standards based on latest knowledge were most indispensable. Strong cooperation among experts in different areas was also needed. (T. Tanaka)

    Due to Fukushima Dai-ichi Nuclear power plant accident occurred in March 2011, large amount of radionuclides was released into the atmosphere and was fallen onto ground by rainfall. Few researches have monitored radioactive cesium dynamics in whole hydrological cycle system such as groundwater, soil water, spring water and stream water. Thus, the purpose of this study is to monitor concentration of radioactive cesium in those waters in time series in the headwaters. We have performed an intensive monitoring at three small mountainous catchments in Yamakiya district, Kawamata town, Fukushima prefecture, locating 35 km northwest from Fukushima Dai-ichi Nuclear Power Plant since June 2011, also we consider the movement of radioactive cesium and its relation with the hydrological cycle.

    Richards Bay, on the northern KwaZulu-Natal coast, is the largest coal exporting port in South Africa. The coal is stored at the Richards Bay Coal Terminal (RBCT) prior to export. Dust from coal operations is a major problem in the Richards Bay area. In this study, we tested the hypothesis that coal dust adversely affects photosynthetic performance of Avicennia marina (Forssk.) Vierh., the dominant mangrove species in the harbour. Photosynthetic performance was determined on 10 trees by measuring carbon dioxide uptake and chlorophyll fluorescence parameters at two elevation sites and on upper and lower leaf surfaces that were covered or uncovered with coal dust. Measurements were made on five clear, sunny days at saturating light (>1000 μmol m -2 s -1 ) and high temperature (28-30 deg. C). Coal dust significantly reduced carbon dioxide exchange of upper and lower leaf surfaces by 17-39%, the reduction being generally greater on the lower leaf surface that is covered by a dense mat of trichomes and salt glands. The reduction in carbon dioxide exchange by coal dust was higher at the high elevation site that supported isolated dwarfed trees. The chlorophyll fluorescence data indicated that leaves coated with dust exhibited significantly lower photosystem II (PS II) quantum yield, lower electron transport rate (ETR) through PSII and reduced quantum efficiency of PSII (F v F m ). The chlorophyll fluorescence data supported the gas exchange measurements and are consistent with reduced photosynthetic performance of leaves coated with coal dust. - Coal dust reduced photosynthetic performance of the mangrove, Avicennia marina

    A total of eight commercial spaceflight participants have launched to the International Space Station (ISS) on Soyuz vehicles. Based on an older mean age compared to career astronauts and an increased prevalence of medical conditions, spaceflight participants have provided the opportunity to learn about the effect of space travel on crewmembers with medical problems. The 12-d Soyuz TMA-13/12 ISS flight of spaceflight participant Richard Garriott included medical factors that required preflight intervention, risk mitigation strategies, and provided the opportunity for medical study on-orbit. Equally important, Mr. Garriott conducted extensive medical, scientific, and educational payload operations during the flight. These included 7 medical experiments and a total of 15 scientific projects such as protein crystal growth, Earth observations/photography, educational projects with schools, and amateur radio. The medical studies included the effect of microgravity on immune function, sleep, bone loss, corneal refractive surgery, low back pain, motion perception, and intraocular pressure. The overall mission success resulted from non-bureaucratic agility in mission planning, cooperation with investigators from NASA, ISS, International Partners, and the Korean Aerospace Research Institute, in-flight support and leadership from a team with spaceflight and Capcom experience, and overall mission support from the ISS program. This article focuses on science opportunities that suborbital and orbital spaceflight participant flights offer and suggests that the science program on Richard Garriott's flight be considered a model for future orbital and suborbital missions. The medical challenges are presented in a companion article.

    We analyzed the effects of the Kampo medicine "Dai-kenchu-to" (DKT) on clinical aspects in colorectal surgery. Total 122 patients who underwent colorectal cancer surgery were divided into a DKT group (n = 53) and a non-DKT group (n = 69). The differences of postoperative course and anti-inflammatory responses between those two groups were analyzed. The 53 out of 59 patients could completely take DKT. In the postoperative course, significant difference was observed in the first flatus day. In the anti-inflammatory effects, differences were observed in the heart rate (HR) of the 3rd POD. In the change between 1st POD and 3rd POD, HR in the DKT group was well controlled compared to the non-DKT group. In the patients who had over 37.5°C of body temperature in 1st POD (n = 53), inflammatory response of the DKT group was reduced compared to the non-DKT group. The DKT might have the favorable influences on postoperative bowel movement and systemic inflammatory reaction, and induce the better postoperative course.

    Diversity of gut microbiome has been recently reported to be lost in inflammatory bowel disease. We have previously reported that the Dai-kenchu-to (DKT) prevented the bacterial translocation through suppression of cytokine and apoptosis in rat's fast stress model. The aim of this study was to evaluate the effect of DKT on maintenance of microbial diversity in rat's intestine with inflammation. Wister rats were received the fast stress for 5 days. In DKT group, rats were administered with DKT (300 mg/kg/day) during the fast stress (DKT-group). The gut microbiomes were analyzed at before- and after- fast stress, and the effect of DKT for on microbial diversities of the gut were evaluated by the PCR-clone library method targeting the 16 S ribosomal RNA gene. In Control-group, Erysipelotrichaceae increased to 86% in after fast stress, OTU of before-fast stress was 111 and after fast stress was only 9 (changing rate: 58%). The diversity of microbiome was severely decreased. On the other hand, in DKT-group, diversity of microbiome was kept after fast stress (Lachnospiraceae: Ruminococcaceae: Coriobacteriales 54%, 22%, 5%), Operational taxonomic units of before fast stress was 52 and after fast stress was 55 (changing rate: 6%). Family Lachnospiraceae which includes butyrate-producing Clostridia (Clostridium IV and XIVa). DKT prevented the reduction of diversity of microbiome in rat's fast stress model. Our data suggested the new anti-inflammatory mechanism of DKT through gut microbiome.

    After hepatic resection, delayed flatus and impaired bowel movement often cause problematic postoperative ileus. Kampo medicine, Dai-kenchu-to (DKT), is reported to have a various beneficial effects on bowel systems. The aim of this study was to prospectively evaluate effects of DKT after hepatic resection. Thirty-two patients who underwent hepatic resection between July 2007 and August 2008 in Tokushima University Hospital were prospectively divided into DKT group (n=16) and control group (n=16). In DKT group, 2.5 g of DKT was administered orally three times a day from postoperative day (POD) 1. Blood was examined on POD 1, 3, 5 and 7. Postoperative first flatus, bowel movement and full recovery of oral intake, hospital stays and complications were checked. In DKT group, levels of c-reactive protein and beta-(1-3)-D-glucan on POD 3 were significantly decreased (pDKT group (pDKT suppressed inflammatory reaction, stimulated bowel movement and improved oral intake after hepatic resection, which may decrease serious morbidity after hepatic resection.

    The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident has caused large amounts of anthropogenic radionuclides to be released into the atmosphere as well as directly discharged into the sea. To obtain the vertical distribution of Pu isotopes in marine sediments and to better assess the possible contamination from the FDNPP accident in the marine environment, activities of "2"3"9"+"2"4"0Pu and "2"4"1Pu, as well as the atom ratios of "2"4"0Pu/"2"3"9Pu and "2"4"1Pu/"2"3"9Pu, were investigated in a sediment core collected from the western North Pacific in July 2011. The observed vertical profile of "2"3"9"+"2"4"0Pu activities and "2"4"0Pu/"2"3"9Pu atom ratios showed no extra injection of Pu from the accident, indicating no immediate Pu contamination from the FDNPP accident in the marine sediments in the region investigated.

    Highlights: • Assesses land management options after the Fukushima accident. • Builds a model for exploring intervention and decontaminations options in areas affected by radioactive contamination. • Findings suggest delaying decontamination efforts by 3–10 years is optimal with a central figure of 8.75 years. • Results are sensitive to estimates of the benefits of resettlement. • Poor state of knowledge about some variables that are key for policy actions, such as psychological benefits and costs of resettlement. -- Abstract: In the light of the Japanese government's intensive efforts to decontaminate areas affected by radioactive Caesium from Fukushima dai-ichi nuclear power plant, I create a framework for assessing the merits of management options. In particular I consider delayed intervention as a possible policy. Delay can be optimal because allowing the natural decay of radiation can lower significantly the costs of achieving targets for exposure. Using some benchmark data for Japan I estimate that optimal delay is positive for most reasonable parameter values. Optimal delay generally lies in the range of 3–10 years with a central figure of 8.8 years. There is however considerable uncertainty over some of the key parameter values, particularly with regard to the behaviour of currently evacuated inhabitants

    The most serious earthquake ever registered in Japan occurred on March 11, 2011; it was followed by a tsunami that flowed over the Prefectures of Miyagi and Fukushima destroying roads, cities and rice fields, but also knocking several nuclear power plants. The Dai-ichi plant was seriously damaged and considerable amounts of radioactivity were release contaminating atmosphere, soil, ocean and associated fauna and flora. A major environmental monitoring program started covering the Japanese territory and the sea along the coasts of Miyagi, Fukushima and Ibaraki. Thousands of measurements were released every day by Japanese authorities, the plant operator and Universities principally looking for the presence of I-131, C{sub s}-134 and C{sub s}-137. Drinking water and aliments were seriously contaminated. We here analyze data released during one year on I-131 and C{sub s}-134,137 radioactive concentrations in cattle meat. Along this period I-131, when observed, was present only in trace amounts, but the contamination by cesium isotopes exceeded legal Japanese limit in several Japanese prefectures, and became an acute national and international economic problem.

    We investigated 134 Cs and 137 Cs activity concentrations in the common Japanese moss species Hypnum plumaeforme collected from 32 sites within ca. 100 km radius of the Fukushima Dai-ichi Nuclear Power Plant. A total of 32 samples of H. plumaeforme were collected during the field surveys from November 2013 to September 2014. The maximum radiocesium activity concentrations in H. plumaeforme were 60.9 ± 1.8 kBq kg -1 for 134 Cs and 123 ± 2.3 kBq kg -1 for 137 Cs. The mean value for the 134 Cs/ 137 Cs was 1.17 ± 0.05, and the mean T ag value was 0.09 ± 0.13. Positive correlations were obtained between total 134 Cs + 137 Cs activity concentrations in H. plumaeforme and the air dose rate with a correlation coefficient (r) of 0.55 (P = 0.001), and between 137 Cs activity concentration in H. plumaeforme and 137 Cs deposition density on soil with r of 0.55 (P = 0.001). These results suggest that the perennial moss species H. plumaeforme could be more suitable and useful as a qualitative indicator for the radiocesium pollution compared to vascular plants spreading over the lowlands including human habitation in Fukushima Prefecture.

    In this study, we investigated the transfer of canopy-intercepted radiocesium to the forest floor following the Fukushima Dai-ichi Nuclear Power Plant accident. The 137 Cs content of throughfall, stemflow, and litterfall were monitored in two coniferous stands (plantations of Japanese cedar) and a deciduous mixed broad-leaved forest stand (oak with red pine) from July 2011 to December 2012. The forest floor of cedar stands had received higher levels of additional 137 Cs deposition compared with the mixed broad-leaved stand during the sampling period. The cumulative 137 Cs deposition during the study period was 119 kBq m -2 for the mature cedar stand, 105 kBq m -2 for the young cedar stand, and 41.5 kBq m -2 for the broad-leaved stand. The deposition of 137 Cs to the forest floor occurred mainly in throughfall during the first rainy season, from July to September 2011 (<200 d after the initial fallout); thereafter, the transfer of 137 Cs from the canopy to forest floor occurred mainly through litterfall. A double exponential field-loss model, which was used to simulate the removal of 137 Cs from canopies, was the best fit for the temporal changes in the canopy 137 Cs inventory.

    We carried out aerial radiation monitoring (ARM) of all Japan area in order to investigate the influence of the radio cesium which was emitted into the atmosphere by disaster of the Fukushima Dai-ichi nuclear power plant of Tokyo Electric Power Co., Inc. AMS can measure a gamma ray quickly by flight from 300 m height above the ground. Moreover, ARM has an advantage which can grasp self-possessed quantity distribution of an air dose rate and radioactive cesium in f ield , and is visually intelligible. Although there were apparatus and the technique of ARM in our country, sufficient preparations for wide area monitoring were not made. Therefore, it fixed based on the method of the U.S. Department of Energy (DOE) about the method of the conversion to all radiation dose, and the conversion method to radiocesium deposition and the method of mapping. It is possible to discriminate from a background (cosmic-ray, self-contamination and natural nuclides) at the time of western-part-of-Japan measurement by improving of the method in parallel to data acquisition. By this monitoring, it was able to check about the distribution situation of the air dose rate of the Japanese whole region, or the radioactive cesium deposition. Here, the measurement technique and a result are described. (author)

    Full Text Available The rate of cesium-137 (137Cs release to the sea from the Fukushima Dai-ichi Nuclear Power Plant for the period until September 2012 was estimated. Publicly released data on 137Cs radioactivity in seawater near the power plant by Tokyo Electric Power Company strongly suggest a continuing release of radionuclides to the sea. The plant has an artificial harbour facility, and the exchange rate of harbour water with surrounding seawater was estimated by the decrease in radioactivity immediately after an intense radioactive water release. The estimated exchange rate of water in the harbour was 0.44 d−1 during the period from 6 to 19 April. The 137Cs radioactivity in the harbour water was substantially higher than that of seawater outside and remained relatively stable after June 2011. A quasi-steady state was assumed with continuous water exchange, and the average release rate of 137Cs was estimated to be 93 GBq d−1 in summer 2011 and 8.1 GBq d−1 in summer 2012.

    Full Text Available Richard II has not often been performed on the French stage; however, in the 20th century, within a period of 35 years, two productions premiered at the same venue (the Cour d’Honneur at the open-air Avignon Festival, were so successful that they became emblematic of their times. In 1947 Jean Vilar opened the first Avignon Festival with an ascetic, charismatic eponymous hero who came to an inner knowledge of himself in his bare prison cell; in 1982 Ariane Mnouchkine offered a splendid visual display by transposing the play into the kabuki tradition; this offered the audience breath-taking and dynamic tableaux of elaborate court ceremonies and rebellious lords.At such a distance in time, the English medieval code of honour was dealt with according to completely different theatrical principles of ethics and aesthetics, mirroring the changes in perspective within French society.

Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

We first present an equivalent formulation of the problem using an Hamilton-Jacobi equation. Then, using a semi-analytic formula, we show that the model constraints resulting from the Hamilton-Jacobi equation result in linear constraints, albeit with unknown integers. We then pose the problem of estimating the density at the initial time given incomplete and inaccurate traffic data as a Mixed Integer Program.

    2012-05-01

    Full Text Available The following article focuses on Richard of St. Victor´s most original treatise: On the Four Degrees of Violent Love. Although the topic of violence within the Christian view on ethics, politics and theology was not at all new by 1173, the major contribution of this short but dense mystical writing consists in developing systematically the violence as an inherent consequence of the infinite charity. The love is so powerful that it “wounds, binds, languishes and brings on a faint”, but the same force may have different effects: if these four steps appear to be destructive when oriented to satisfy the “profane” desires, their infinite strength show providential effects when turned to the divine source of the charity.

    Radioactive cesium ((134)Cs and (137)Cs) concentrations in invertebrates of benthic food web (10 taxonomic classes with 46 identified families) collected from wide areas off Fukushima Prefecture (3-500 m depth) were inspected from July 2011, four months after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, to August 2013 to elucidate time-series trends among taxa and areas. Cesium-137 was detected in seven classes (77% of 592 specimens). Higher (137)Cs concentrations within detected data were often found in areas near or south of the FDNPP, which is consistent with the reported spatial distribution of (137)Cs concentrations in highly contaminated seawater and sediments after the FDNPP accident. Overall (137)Cs concentrations in invertebrates, the maxima of which (290 Bq kg(-1)-wet in the sea urchin Glyptocidaris crenularis) were lower than in many demersal fishes, had decreased exponentially with time, and exhibited taxon-specific decreasing trends. Concentrations in Bivalvia and Gastropoda decreased clearly with respective ecological half-lives of 188 d and 102 d. In contrast, decreasing trends in Malacostraca and Polychaeta were more gradual, with longer respective ecological half-lives of 208 d and 487 d. Echinoidea showed no consistent trend, presumably because of effects of contaminated sediments taken into their digestive tract. Comparison of (137)Cs concentrations in the invertebrates and those in seawater and sediments suggest that contaminated sediments are the major source of continuing contamination in benthic invertebrates, especially in Malacostraca and Polychaeta.

    Tottori University and the Japan Atomic Energy Agency carried out jointly the feasibility study on phyto-remediation techniques, which apply to soil contaminated by the TEPCO's Fukushima Dai-ichi NPP accident. This paper illustrates the results from experimental investigations. Experimental investigations include both water-culture tests and field tests. Several plants, mainly halophytes that can specifically absorb more Na than K, and others like sunflower demonstrated for other domestic large-scale tests, were water-cultured and examined for screening. Easily cultivated and harvested plants without harmful effects on subsequent cultivation were also considered. New Zealand spinach was selected as a candidate for demonstrations in fields. The field tests were carried out at two sites of different agricultural types in Minami-soma, Fukushima prefecture. Concentration of {sup 137}Cs in soil is about 4.5 Bq/g-dry as the average of 10 cm depth. The aims of the field tests are to confirm absorption ability and environmental adaptation of the test plants and to document the cost and performance of projects. In conclusion, the absorption of {sup 137}Cs activity per unit area (Bq/m{sup 2}) by New Zealand spinach could be approximately 0.5%. To achieve an effective result in removal of {sup 137}Cs from soil in around a decade, it is required to find the plant which has ten or more times higher absorption capacity than New Zealand spinach. From the consistency of both results in water-culture and field tests, the water-culture test can be valid for screening. In addition, applicable sites will be limited to fields which are too steep or too narrow to use mechanical diggers, and which are free from any restrictions to enter. (authors)

    Radiocesium migration from headwater forested catchment is important perception as output from the forest which is also input to the subsequent various land use and downstream rivers after Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. In this study, Cs-137 concentration of dissolved water, suspended sediment and coarse organic matter such as leaf and branch were monitored. Discharge amount of stream water, suspended sediment and coarse organic matter were measured to investigate the discharge amount of radiocesium and composition of radiocesium discharge form through the headwater stream. Observation were conducted at stream site in four headwater catchments in Yamakiya district, located ~35 km north west of FDNPP from June 2011 (suspended sediment and coarse organic matter: August 2012) to December 2014.The Cs-137 concentration of dissolved water was around 1Bq/l at June 2011. Then declined to 0.1 Bq/l at December 2011. And in December 2014, it declined to 0.01 Bq/l order. Declining trend of Cs-137 concentration in dissolved water was expressed in double exponential model. Also temporary increase was observed in dissolved Cs-137 during the rainfall event. The Cs-137 concentration of suspended sediment and coarse organic matter were 170-49000 Bq/kg and 350-14000 Bq/kg respectably. The Cs-137 concentration of suspended sediment showed good correlation with average deposition density of catchment. The effect of decontamination works appeared in declining of Cs-137 concentration in suspended sediment. Contribution rate of Cs-137 discharge by suspended sediment was 96-99% during a year. Total annual Cs-137 discharge from the catchment were 0.02-0.3% of the deposition.

  3. A backward method to estimate the Dai-ichi reactor core damage using radiation exposure in the environment

    The Fukushima accident resulted in the melting of the reactor core due to loss of supply of coolant when the reactor stopped from operating conditions. The earthquake and tsunami caused loss of electricity due to the flooding that occurred in the reactor. The absence of the coolant supply after reactor shutdown resulted in heat accumulation, causing the temperature of the fuel to rise beyond its melting point. In the early stages of the accident, operator could not determine the severity of the accident and the percentage of the reactor core damaged. The available data was based on the radiation exposure in the environment that was reported by the authorities. The aim of this paper is to determine the severity of the conditions in the reactor core based on the radiation doses measured in the environment. The method is performed by backward counting based on the measuring radiation exposure and radionuclides releases source term. The calculation was performed by using the PC-COSYMA code. The results showed that the core damage fraction at Dai-ichi Unit 1 was 70%, and the resulting individual effective dose in the exclusion area is 401 mSv, while the core damage fraction at Unit 2 was 30%, and the resulting individual effective dose was 9.1 mSv, while for Unit 3, the core damage fraction was 25% for an individual effective dose of 92.2 mSv. The differences between the results of the calculation for estimation of core damage proposed in this paper with the previously reported results is probably caused by the applied model for assessment, differences in postulations and assumptions, and the incompleteness of the input data. This difference could be reduced by performing calculations and simulations for more varied assumptions and postulations. (author)

    The large amount of 137 Cs deposited on the forest floor because of the Fukushima Dai-ichi Nuclear Power Plant accident represents a major potential long-term source for mobile 137 Cs. To investigate 137 Cs mobility in forest soils, we investigated the vertical migration of 137 Cs through seepage water, using a lysimetric method. The study was conducted in a deciduous forest soil over a period spanning 2 month to 2 y after the Fukushima nuclear accident. Our observations demonstrated that the major part of 137 Cs in the litter layer moved into the mineral soil within one year after the accident. On the other hand, the topsoil prevented migration of 137 Cs, and only 2% of 137 Cs in the leachate from litter and humus layer penetrated below a 10 cm depth. The annual migration below a 10 cm depth accounted for 0.1% of the total 137 Cs inventory. Therefore, the migration of 137 Cs by seepage water comprised only a very small part of the total 137 Cs inventory in the mineral soil, which was undetectable from the vertical distribution of 137 Cs in the soil profile. In the present and immediate future, most of the 137 Cs deposited on the forest floor will probably remain in the topsoil successively, although a small but certain amount of bioavailable 137 Cs exists in forest surface soil. -- Highlights: • Lysimeter captured 137 Cs mobility in a forest soil after the Fukushima accident. • Major part of 137 Cs in the litter layer moved into the mineral soil within a year. • Litter-leachate 137 Cs was predominantly adsorbed within the topsoil. • The annual migration below a 10 cm depth was 0.1% of the total 137 Cs inventory

  5. Modelling the transport of radioactive cesium released from the Fukushima Dai-ichi NPP with sediments through the hydrologic system

    Due to the accident of the Fukushima Dai-ichi Nuclear Power Plant on March 2011, a huge amount of radionuclides including Cesium-134 and Cesium-137 was deposited over the main island of Japan and the Pacific Ocean, resulting in further transfer and diffusion of Cesium through the atmospheric flow, watershed hydrological processes, and terrestrial ecosystem. Particularly, for the transfer of Cesium-134 and Cesium-137, sediments eroded and transported by the rainfall-runoff processes play an important role as Cesium tends to be strongly adsorbed to soil particles such as clay and silt. In this study, we focus on the transport of sediment and adsorbed Cesium in the watershed-scale hydrologic system to predict the long-term change of distribution of Cesium and its discharge to rivers and ocean. We coupled a physically-based distributed hydrological model with the modules of erosion and transport of sediments and adsorbed Cesium, and applied the coupled model to the Abukuma River watershed, which is located over the area of higher deposition of Cesium. In the model, complex land use and land cover distributions, and the effect of human activities such as irrigation, dam control and urban drainage system are taken into accounts. Simulation was conducted for the period of March 2011 until August 2012, with initial spatial distribution of Cesium-134 and Cesium-137 obtained by the airborne survey. Simulated flow rates and sediment concentrations agreed well with observed, and found that since the accident, two major storms in July and September 2011 transported about 50% of total sediments transported during the simulated periods. Cesium concentration in the sediment was reproduced well except for the difference in the initial periods. This difference is attributable to the uncertainty arisen from the initial distribution of Cesium in the soil and the transfer of Cesium from the forest canopy.

    Full Text Available In general, two theories or school of thoughts had been prevailed in modern moral philosophies until recently. Ethical school of thought of "task-oriented", in which the emphasis is on the nature of the action. At first, this school of thought was considered by Immanuel Kant. Accordingly, doing or will to do every action should be such that become a universal moral law. In contrast, another ethical school of thought known as "utilitarianism ethics" was introduced by Jeremy Bentham and John Stuart Mill. Here, we give priority to those moral actions that can bring the greatest happiness for most people. In three or four recent decades, coinciding with the linguistic and cognitive turn, which has become known as the transition from positivism to post-positivism, another challenge has been raised in discussing philosophy of ethics by Richard Rorty which is related to his claim regarding the requirements of the current multiple world. This claim can make a new relation between morality and human rights. Hence, the main hypothesis of this paper is to clarify the point that Rorty has raised his claim by combining the theory of pragmatism and postmodern Ethics. To prove this hypothesis, this article has been set in two sections, in the first section in order to become familiar with Rorty's creed-breaker thought, the foundations of the philosophy of ethics is discussed. In the second section and under the discussion of ethics based on the rights of human, some of its characteristics will be analyzed. This article has been prepared by a descriptive method through the content analysis of various works of Rorty. Theoretical support for this article is a critical-normative approach. به طور کلی در فلسفه‌های اخلاق مدرن تا این اواخر دو نگره یا مکتب حاکم بوده است. مکتب اخلاق «وظیفه‌گرا»که در آن بر ماهیت کنش تأکید می‌شود. این مکتب ابتدا

    Fukushima Dai-ichi Nuclear Power Plant is the oldest among three nuclear power plants owned and operated by Tokyo Electric Power Company, which consists of six boiling water reactor units. The commercial operation of Unit 1 was commenced in 1971 (37 years old) and Unit 6 in 1978 (29 years old). Currently ageing degradations of systems, structures and components are managed through maintenance programs, component replacement/refurbishment programs and long-term maintenance plans. The long-term maintenance plans are established through ageing management component replacement/refurbishment programs reviews performed before the 30th year of operation and they are for safe and reliable operation after 30 years (long-term operation). However the past maintenance actions and past component replacement/refurbishment programs were not always proactive and past operational experience and maintenance practices suggest that effective/proactive ageing management programs be introduced in earlier stage of the plant operation. In this circumstance, Tokyo Electric Power Company and Fukushima Dai-ichi Nuclear Power Plant are setting up a new maintenance strategy that includes 1) improving the normal maintenance programs by using ageing degradation data, 2) effective use of information on internal/external operational experience and maintenance practices related to ageing, and 3) proactive component/equipment refurbishment programs during a refreshment outage for safe and reliable long-term operation. To accomplish the goal of this strategy, strengthening engineering capability of plant staff members is a crucial required for the plant. The objective of this paper is to briefly explain main results ageing management reviews, past and current significant ageing issues and management programs against them, and the new maintenance strategy established by Tokyo Electric Power Company and Fukushima Dai-ichi Nuclear Power Plant.

    The 3D compartment model POSEIDON-R was applied to the Northwestern Pacific and adjacent seas to simulate the transport and fate of {sup 90}Sr in the period 1945–2010 and to perform a radiological assessment on the releases of {sup 90}Sr due to the Fukushima Dai-ichi nuclear accident for the period 2011–2040. The contamination due to runoff of {sup 90}Sr from terrestrial surfaces was taken into account using a generic predictive model. A dynamical food-chain model describes the transfer of {sup 90}Sr to phytoplankton, zooplankton, molluscs, crustaceans, piscivorous and non-piscivorous fishes. Results of the simulations were compared with observation data on {sup 90}Sr for the period 1955–2010 and the budget of {sup 90}Sr activity was estimated. It was found that in the East China Sea and Yellow Sea the riverine influx was 1.5% of the ocean influx and it was important only locally. Calculated concentrations of {sup 90}Sr in water, bottom sediment and marine organisms before and after the Fukushima Dai-ichi accident are in good agreement with available experimental measurements. The concentration of {sup 90}Sr in seawater would return to the background levels within one year after leakages were stopped. The model predicts that the concentration of {sup 90}Sr in fish after the Fukushima Dai-ichi accident shall return to the background concentrations only 2 years later due to the delay of the transfer throughout the food web and specific accumulation of {sup 90}Sr. The contribution of {sup 90}Sr to the maximal dose rate due to the FDNPP accident was three orders of magnitude less than that due to {sup 137}Cs, and thus well below the maximum effective dose limits for the public. - Highlights: • A box model with a dynamical food-chain model for the NW Pacific was applied. • The transport and fate of {sup 90}Sr in sea were simulated for the period 1945–2040. • Marine exposure pathways for {sup 90}Sr were assessed for the Fukushima Dai-ichi accident.

    The compartment model POSEIDON-R was modified and applied to the Northwestern Pacific and adjacent seas to simulate the transport and fate of radioactivity in the period 1945–2010, and to perform a radiological assessment on the releases of radioactivity due to the Fukushima Dai-ichi accident for the period 2011–2040. The model predicts the dispersion of radioactivity in the water column and in sediments, the transfer of radionuclides throughout the marine food web, and subsequent doses to humans due to the consumption of marine products. A generic predictive dynamic food-chain model is used instead of the biological concentration factor (BCF) approach. The radionuclide uptake model for fish has as a central feature the accumulation of radionuclides in the target tissue. The three layer structure of the water column makes it possible to describe the vertical structure of radioactivity in deep waters. In total 175 compartments cover the Northwestern Pacific, the East China and Yellow Seas and the East/Japan Sea. The model was validated from 137 Cs data for the period 1945–2010. Calculated concentrations of 137 Cs in water, bottom sediments and marine organisms in the coastal compartment, before and after the accident, are in close agreement with measurements from the Japanese agencies. The agreement for water is achieved when an additional continuous flux of 3.6 TBq y −1 is used for underground leakage of contaminated water from the Fukushima Dai-ichi NPP, during the three years following the accident. The dynamic food web model predicts that due to the delay of the transfer throughout the food web, the concentration of 137 Cs for piscivorous fishes returns to background level only in 2016. For the year 2011, the calculated individual dose rate for Fukushima Prefecture due to consumption of fishery products is 3.6 μSv y −1 . Following the Fukushima Dai-ichi accident the collective dose due to ingestion of marine products for Japan increased in 2011 by a

    Radioactive nuclides were released in the atmosphere by the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station in March, 2011, and they are detected on the materials that had no artificial radioactive nuclides before the accident. Confronted with this situation, NISA issued a guideline titled 'A guideline regarding treatment of materials in nuclear facilities considering the influence of fallout released from the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station' on March 30, 2012. The guideline shows that after judging whether there is the influence of fallout or not, the conventional clearance and NR systems can be used when there is no influence of fallout. On the other hand, the special treatment is required when it is judged that there is the influence. This report describes that a specific example of measuring method of the surface contamination of the materials for the judgment of the influence of fallout. 'The precautionary measurement' defined in NR system is useful for the judgment of the influence of fallout. The criterion of the judgment is the theoretical detection limit. Sampling points for the measurement should be selected depending on expected contamination status of the survey target, considering the site area, the states of facilities or equipments and airflow from outside of the facilities. Sampling number for the fallout should be greater than equal to 10. (author)

    Average burnup of damaged fuels loaded in Fukushima Dai-ichi reactors is estimated, using the 134 Cs/ 137 Cs ratio method for measured radioactivities of 134 Cs and 137 Cs in contaminated soils within the range of 100 km from the Fukushima Dai-ichi nuclear power plants. As a result, the measured 134 Cs/ 137 Cs ratio from the contaminated soil is 0.996±0.07 as of March 11, 2011. Based on the 134 Cs/ 137 Cs ratio method, the estimated burnup of damaged fuels is approximately 17.2±1.5 [GWd/tHM]. It is noted that the numerical results of various calculation codes (SRAC2006/PIJ, SCALE6.0/TRITON, and MVP-BURN) are almost the same evaluation values of 134 Cs/ 137 Cs ratio with same evaluated nuclear data library (ENDF-B/VII.0). The void fraction effect in depletion calculation has a major impact on 134 Cs/ 137 Cs ratio compared with the differences between JENDL-4.0 and ENDF-B/VII.0. (authors)

  16. Some lessons on radiological protection learnt from the accident at the Fukushima Dai-ichi nuclear power plant

    The accident at the Fukushima Dai-ichi nuclear power plant released a large quantity of radioactive iodine and caesium into the environment. In terms of radiological protection, the evacuation and food restrictions that were adopted in a timely manner by the authorities effectively reduced the dose received by people living in the affected area. Since late March, the transition from an emergency to an existing exposure situation has been in progress. In selecting the reference exposure levels in some areas under an existing exposure situation, the authorities tried to follow the situation-based approach recommended by the ICRP. However, a mixture of emergency and post-emergency approaches confused the people living in the contaminated areas because the reactor conditions continued to be not completely stable. In deriving the criteria in an existing exposure situation, the regulatory authority selected 20 mSv y −1 . The mothers in the affected area believed that a dose of 20 mSv y −1 was unacceptably high for children since 1 mSv y −1 is the dose limit for the public under normal conditions. Internet information accelerated concern about the internal exposure to children and the related health effects. From some experiences after the accident the following lessons could be learned. The selection of reference doses in existing exposure situations after an accident must be openly communicated with the public using a risk-informed approach. The detriment-adjusted nominal risk coefficient was misused for calculating the hypothetical number of cancer deaths by some non-radiation experts. It would not be possible to resolve this problem unless the ICRP addressed an alternative risk assessment to convey the meaning and associated uncertainty of the risk to an exposed population. A situation-based approach in addition to a risk-informed approach needs to be disseminated properly in order to select the level of protection that would be the best possible under the

    After the Fukushima Dai-ichi Nuclear Power Plant accident on March 2011, continuous monitoring of the detailed vertical distribution of radiocesium in soil is required to evaluate the fate of radiocesium and establish strategies for remediation and management of the contaminated land. It is especially important to investigate paddy soil because little knowledge has been accumulated for paddy soil and wetland rice is a major staple in Japan. Therefore, we monitored the vertical distribution of 137 Cs in abandoned paddy soil in a planned evacuation zone from June 2011 to March 2016. The decontamination works (i.e., 5 cm of surface soil removal and re-covering with uncontaminated soil) were conducted by the government in 2015. As a result of monitoring, the 137 Cs gradually migrated downward with time and the 137 Cs concentration in the 0-10 cm soil was almost homogenous in October 2014, although it was non-cultivated. The liner relationship was obtained between the median depth, which is the thickness of a soil layer containing half of the total 137 Cs inventory, and the time after the accident, indicating the migration rate was constant (1.3 cm y -1 ) before the decontamination works. After the decontamination works, the 137 Cs concentration in the uppermost surface layer was reduced by 90%, however the total 137 Cs inventory was reduced by only 50-70%. It was shown that the efficiency of 137 Cs removal by the decontamination works decrease linearly over time in fields like the studied paddy, in which the homogenization of 137 Cs concentration occurred. Conversely, the downward migration of 137 Cs to subsurface layers deeper than 10 cm (i.e., plowpan layer) with low permeability rarely occurred. It is expected that these unique trends in distribution and migration of 137 Cs would be found in abandoned paddy soils with properties similar to the studied soil, sandy loam but poorly drained because of the low permeable plowpan layer, although further validation is

    Full Text Available The impact of the earthquake and tsunami on the east coast of Japan on 11 March 2011 caused a loss of power at the Fukushima Dai-ichi nuclear power plant (NPP that resulted in one of the most important releases of artificial radioactivity into the environment. Although several works were devoted to evaluating the atmospheric dispersion of radionuclides, the impact of the discharges to the ocean has been less investigated. Here we evaluate the distribution of Fukushima-derived 90Sr (n = 57 and 89Sr (n = 19 throughout waters 30–600 km offshore in June 2011. Concentrations of 90Sr and 89Sr in both surface waters and shallow profiles ranged from 0.8 ± 0.2 to 85 ± 3 Bq m−3 and from 19 ± 6 to 265 ± 74 Bq m−3, respectively. Because of its short half-life, all measured 89Sr was due to the accident, while the 90Sr concentrations can be compared to the background levels in the Pacific Ocean of about 1.2 Bq m−3. Fukushima-derived radiostrontium was mainly detected north of Kuroshio Current, as this was acting as a southern boundary for transport. The highest activities were associated with near-shore eddies, and larger inventories were found in the closest stations to Fukushima NPP. The data evidence a major influence of direct liquid discharges of radiostrontium compared to the atmospheric deposition. Existing 137Cs data reported from the same samples allowed us to establish a 90Sr / 137Cs ratio of 0.0256 ± 0.0006 in seawater off Fukushima, being significantly different than that of the global atmospheric fallout (i.e., 0.63 and may be used in future studies to track waters coming from the east coast of Japan. Liquid discharges of 90Sr to the ocean were estimated, resulting in an inventory of 53 ± 1 TBq of 90Sr in the inshore study area in June 2011 and total releases of 90Sr ranging from 90 to 900 TBq, depending upon the reported estimates of 137Cs releases that are considered.

    Anthropogenic radionuclides such as Pu-239 (half-life: 24100 yr), Pu-240 (half-life: 6560 yr) and Pu-241 (half-life: 14.325 yr) mainly have been released into the environment as the result of atmospheric nuclear weapons testing. In the North Pacific Ocean, two distinct sources of Pu isotopes can be identified; i.e., the global stratospheric fallout and close-in tropospheric fallout from nuclear weapons testing at the Pacific Proving Grounds in the Marshall Islands. The atom ratio of Pu-240/Pu-239 is a powerful fingerprint to identify the sources of Pu in the ocean. The Pu-240/Pu-239 atom ratios in seawater and marine sediment samples collected in the western North Pacific before the accident at Fukushima Dai-ichi Nuclear Power Station will provide useful background data for understanding the process controlling Pu transport and for distinguishing future Pu sources. The atom ratios of Pu-240/Pu-239 in water columns from the Yamato and Tsushima Basins in the Japan Sea were significantly higher than the mean global fallout ratio of 0.18; however, there were no temporal variation of atom ratios during the period from 1984 to 1993 in the Japan Sea. The total Pu-239+240 inventories in the whole water columns were approximately doubled during the period from 1984 to 1993 in the two basins. The atom ratio of Pu-240/Pu-239 in surface water from Sagami Bay, western North Pacific Ocean, was 0.224 and showed no notable variation from the surface to the bottom with the mean atom ratio being 0.234. The atom ratios for the Pacific coast, near the Rokkasho nuclear fuel reprocessing plant, were approximately the same as the 0.224 ratio obtained from Sagami Bay, western North Pacific margin. The atom ratios in the surficial sediments from Sagami Bay ranged from 0.229 to 0.247. The mean atom ratio in the sediment columns in the East China Sea ranged from 0.248 for the Changjiang estuary to 0.268 for the shelf edge. The observed atom ratios were significantly higher than the mean

    A 50-year-old Japanese cedar (Cryptomeria japonica) from Okuma, ∼1 km southwest of the Fukushima Dai-ichi Nuclear Power Plant, was cored and each annual ring was analysed for 14 C. The 14 C specific activity values varied from 330.4 Bq kg −1  C in the tree ring formed in 1971 to 231.2 Bq kg −1  C in the 2014 ring. During the periods 1971–1976 and 2011–2014, the 14 C specific activities are indistinguishable from the ambient background values. However, compared with the ambient atmospheric levels, the 14 C specific activities between 1977 and 2010 are significantly elevated, clearly indicating 14 C discharges from the reactors during their normal operations. In addition, the specific activities are positively correlated with the annual electricity generation values. The excess 14 C specific activities were <36 Bq kg −1  C, corresponding to an additional annual effective dose of <2 μSv via the food ingestion pathway in the study location. The primary wind direction is east-southeast/southeast with a frequency of ∼30%, in comparison to ∼20% frequency for the direction of the site under study (north-northeast/northeast). This would tend to indicate a similar magnitude of additional effective dose and consequently no significant radiological impact of atmospheric 14 C discharges from the FDNPP during the entire period of normal operations. Additionally, no 14 C pulse in activity can be observed in the year 2011 ring. This might be caused by a limited 14 C release from the damaged reactors during the accident or that the prevailing wind during the short period of release (11th–25th March 2011) was not in the direction of Okuma. - Highlights: • The 14 C variation in 1971–1976 and 2011–2014 is ascribed as an exponential decline. • The 14 C discharge from FDNPP normal operation caused 14 C enrichment in 1977–2010. • Total 53 TBq 14 C were released during the whole period of the normal operations. • No visible accident 14 C pulse

    Bunkyo-ku is located in the eastern part of the metropolitan area of Tokyo, Japan, and is roughly 220 km south of the TEPCO Fukushima Dai-ichi Nuclear Power Plant. The population of the city was 201,079 as of August 1, 2012, and its area is 11.31 km"2. The local government has officially been surveying the environmental radiation status after the disaster in response to numerous requests from its citizens. The radiation surveillance in this area has been technically guided by radiation protection specialists. The two main targets for surveillance are (1) the ambient radiation dose (microsieverts per hour) at all the school yards, public parks, and representative measurement points selected by the local government, and (2) the specific radioactivity (becquerels per kilogram) present in school lunch. These data have been reported to the citizens through the city website as well as in a bi-monthly report in the public relations magazine of the local government. This report presents the background status and technical information of the related activities, as well as the measured environmental radiation data. The ambient radiation dose in the city has been surveyed since July 2011. In the 1st period of surveillance (from July to August, 2012), over a total of 304 measurement points, the highest recorded value of the ambient radiation dose was 0.22 μSv h"-"1 at the height of 1 m from the ground, the lowest was 0.05 μSv h"-"1, and the average was around 0.09 μSv h"-"1. These values include the natural background dose rate detected by the energy compensation type surveymeters. In the most recent surveillance records, the maximum value recorded was 0.10, the minimum was 0.05, and 0.07 μSv h"-"1 was the average value. The specific radioactivity of drinking water has been monitored at local purification plants since the accident occurred. No water sample supplied to the city has exceeded the national limits for intake dose. The specific radioactivity of school lunch was

    2015-12-01

    Hydrologic modelers and mathematicians have strived to improve 1-D Richards' equation (RE) solution reliability for predicting vadose zone fluxes. Despite advances in computing power and the numerical solution of partial differential equations since Richards first published the RE in 1931, the solution remains unreliable. That is to say that there is no guarantee that for a particular set of soil constitutive relations, moisture profile conditions, or forcing input that a numerical RE solver will converge to an answer. This risk of non-convergence renders prohibitive the use of RE solvers in hydrological models that need perhaps millions of infiltration solutions. In lieu of using unreliable numerical RE solutions, researchers have developed a wide array of approximate solutions that more-or-less mimic the behavior of the RE, with some notable deficiencies such as parameter insensitivity or divergence over time. The improved Talbot-Ogden (T-O) finite water-content scheme was shown by Ogden et al. (2015) to be an extremely good approximation of the 1-D RE solution, with a difference in cumulative infiltration of only 0.2 percent over an 8 month simulation comparing the improved T-O scheme with a RE numerical solver. The reason is that the newly-derived fundamental flow equation that underpins the improved T-O method is equivalent to the RE minus a term that is equal to the diffusive flux divided by the slope of the wetting front. Because the diffusive flux has zero mean, this term is not important in calculating the mean flux. The wetting front slope is near infinite (sharp) in coarser soils that produce more significant hydrological interactions between surface and ground waters, which also makes this missing term 1) disappear in the limit, and, 2) create stability challenges for the numerical solution of RE. The improved T-O method is a replacement for the 1-D RE in soils that can be simulated as homogeneous layers, where the user is willing to neglect the effects

Their heroes act as non-mystical pilgrims to whom the trip is a journey in itself, even if they come up as a chase, a car race or an escape from the police.In a filmic genre built from the spatial element, the road life structures each narrative in each film. In this way, the moment when the journey looses its teleological sense acquires even more relevance, allowing us to understand the genre’s space dynamics with a different depth.In this essay, I will analyse comparatively the ways through which characters and directors relate to the scenery/landscape, in order to identify ideological constraints related to space, i.e., those symbolic limitations the road movie seems to conceal. Easy Rider (Dennis Hopper, 1969 will be a constant presence since, as the inaugural road movie, it has determined the genre’s underlying forces.

  5. An analytical solution of Richards' equation providing the physical basis of SCS curve number method and its proportionality relationship

    The empirical proportionality relationship, which indicates that the ratio of cumulative surface runoff and infiltration to their corresponding potentials are equal, is the basis of the extensively used Soil Conservation Service Curve Number (SCS-CN) method. The objective of this paper is to provide the physical basis of the SCS-CN method and its proportionality hypothesis from the infiltration excess runoff generation perspective. To achieve this purpose, an analytical solution of Richards' equation is derived for ponded infiltration in shallow water table environment under the following boundary conditions: (1) the soil is saturated at the land surface; and (2) there is a no-flux boundary which moves downward. The solution is established based on the assumptions of negligible gravitational effect, constant soil water diffusivity, and hydrostatic soil moisture profile between the no-flux boundary and water table. Based on the derived analytical solution, the proportionality hypothesis is a reasonable approximation for rainfall partitioning at the early stage of ponded infiltration in areas with a shallow water table for coarse textured soils.

    Full Text Available O texto discute o sentido polémico do “regresso” a África que Richard Wright inscreve em Black Power e a forma como a narrativa da viagem subverte a “Middle Passage”. O sujeito narrativo orienta o leitor através de uma incursão pessoal nos muitos sentidos da modernidade e desdobra a noção de “destino comum”, já apontada em 12 Million Black Voices. Contudo, qualquer sentido de comunidade é aqui necessariamente ambíguo, por estar sempre relacionado com questões de raça e identidade. Black Power é uma narrativa importante para o conceito de modernidade e assinala uma mudança significativa na produção literária de Wright para uma vertente não-ficcional. Esta segunda fase da sua obra contém, no entanto, um paradoxo crucial: enquanto se volta para o exterior, para o mundo mais global, Wright tenta, simultaneamente, inscrever-se como referência sobre o locus do qual nunca poderia demarcar‑se: África. Em Black Power, a duboisiana “color line” desdobra‑se em múltiplas dimensões.

  7. ‘The Edification of the Church’: Richard Hooker’s Theology of Worship and the Protestant Inward / Outward Disjunction

    Full Text Available Sixteenth-century English Protestants struggled with the legacy left them by the Lutheran reformation: a strict disjunction between inward and outward that hindered the development of a robust theology of worship. For Luther, outward forms of worship had more to do with the edification of the neighbour than they did with pleasing God. But what exactly did ‘edification’ mean? On the one hand, English Protestants sought to avoid the Roman Catholic view that certain elements of worship held an intrinsic spiritual value; on the other hand, many did not want to imply that forms of worship were spiritually arbitrary and had a merely civil value. Richard Hooker developed his theology of worship in response to this challenge, seeking to maintain a clear distinction between the inward worship of the heart and the outward forms of public worship, while refusing to disassociate the two. The result was a concept of edification which sought to do justice to both civil and spiritual concerns, without, pace Peter Lake and other scholars, conceding an inch to a Catholic theology of worship

    Mereology, is a part-whole theory, also called the theory of collective sets. It was founded in 1916 by Stanisław Leśniewski and this is an alternative theory versus the classical set theory by Georg Cantor. These two theories are usually teamed up together as Leśniewski himself was referring to the concept of the set by Cantor and Cantor is considered the "main" ideologist of the set theory. However, when analyzing the original texts of various authors, it seems that the very concept of a collective set is closer to the idea of Richard Dedekind rather than that of Georg Cantor. It is known that Cantor borrowed some concepts on the notion of set from Dedekind, whose ideas were also known to Leśniewski, however, there is no study on this topic. This work is therefore an attempt to compare some set-theoretical concepts of both of these authors, i.e. S. Leśiewski and R. Dedekind and the presentation of their convergence.

    民国初期的回族虽然在经济及社会发展方面仍在较低层次上徘徊,但在思想与文化方面却受到近世以来涌入中国的新思潮、新文化气象以及国内新文化运动的影响,出现了回族新文化运动的热潮,回族知识分子一方面以兴学校、办报刊觉醒民众,另一方面也对回族宗教与社会习俗进行反思与改革,要求回族在应对时代变化中实现自身的社会发展。宗教观念上大力提倡“理性”与“改良”意识,对一些闭塞与异化的宗教观念要求“正本清源”,力求“精义”;在回族社会生活习俗方面则更多地强调与新事物之间要“适应”与“协调”。%Although the Hui nationality' s social and economic development in the early Republic of China and is at a low level, their ideological and cultural are affected by the new ideas, the new culture atmosphere , the new culture movement pouring into modern China. The emergence of Hui nationality' s new culture movement appeared, the HUI intellectuals arouse people by establishing schools, publishing newspapers on one hand and ask the Hui nationality to realize the social self - development by reflecting and innovating from the social customs and the I-Iui nationality' s religious on the other. The consciousness of rationality and improvement are advocated in religious consciousness, and some closed and alienated religious consciousness has been reformed radically and aimed for essence. The adaptation and coordination for the new things are more emphasized in the Hui nationality' s social life and custom.

    Dai Zhen was known as a leading proponent of the evidential research (kaozheng school during the Qian Jia Era. However, he regarded kaozheng as primarily a means of revealing the truth. Moreover, he was regarded as a philosopher rather than as merely a kaozheng, or textual, scholar. In this respect, his philosophical writings reflect an attempt to substitute his own philosophy for the Song Philosophy of Principle (lixue. Dai Zhen’s philosophical writings indicate the impact philology had on philosophical issues. The methodology Dai Zhen adopted was essentially linguistic, that is, xungu (etymology, lit., “glossing”. The merit of this methodology was that it would trace back the original meanings of key terms in the Classics, and this in turn, would benefit the understanding of the Confucian tradition. The aim of this paper is to explore Dai Zhen’s attempt to reconstruct the Confucian tradition, and to assess his philosophy of evidential research in order to manifest its value and limitation.

  12. Reply to Comment by Cole-dai Et Al. on "Climatic Impact of the Long-lasting Laki Eruption: Inapplicability of Mass-independent Sulfur Isotope Composition Measurements"

    2014-01-01

    Here we respond to the comments by Cole-Dai et al. [2014] on our article Schmidt et al. [2012]. Specifically, in response to section 2 of their reply, we argued in Schmidt et al. [2012] that based on previously published estimates of the volatile release height during the 1783-1784 C.E. Laki eruption, the lack of a sulfur massindependent fractionation (MIF) anomaly is expected. In other words, no previous study on Laki ever argued that this eruption emitted SO2 into altitudes >13-15 km. In section 2.3, Cole-Dai et al. [2014] argue that the nonzero ?33S value of their Laki sample 1 may be explained by a short-lived explosive phase at Laki during which volatiles reached the stratosphere. In Schmidt et al. [2012] in section 2, we argued in agreement with Cole-Dai et al. [2014] (section 3.1) that for a MIF anomaly to be preserved, the Laki volatiles would have had to be emitted in >20 km altitude. Our main point is that eruption column heights >20 km are unlikely based on the historical accounts and plume-rise modeling for the Laki eruption [Stothers et al., 1986; Woods, 1993; Thordarson and Self, 2003]. In Schmidt et al. [2012], we argued that to deduce a short-lived climatic impact of the Laki eruption based on the lack of a MIF anomaly and the length of the sulfate deposition in Greenland ice cores may be misleading because the climatic impact will outlast the radiative forcing of the Laki aerosol cloud. Cole-Dai et al. [2014] acknowledge the latter in their reply in section 4.2. We agreewith Cole-Dai et al. [2014] in that themagnitude and length of the climatic impact during the winter of 1783-1784 depends on the altitude of the volatile release during the eruption (sections 2.3 and 4.2). However, even if we assumed that during Laki all sulfur dioxide (SO2) would have been released in the troposphere, then the aerosol cloud would still be present in the upper troposphere during March 1784, as is evident from independent model simulations of this "tropospheric

    The concept of acupuncture point localisation in Traditional Chinese Medicine (TCM) is based on millenary practical experience. Modern imaging methods such as PET, MRI and SPECT have been used primary for the investigation of the mechanisms of action of acupuncture. In this pilot single-case study we have evaluated the technical possibilities for in-vivo imaging of the anatomical relations of acupuncture points using state of the art MRI. Preliminary experiments relating to the quality of acupuncture needles under the setting of MRI were done both with stainless steel and gold needles. In a second step, in-vivo imaging was carried out. A licensed acupuncture practitioner (RM) chose two points belonging to the so-called extraordinary vessels. In 2 sequential, separate procedures, he inserted himself gold acupuncture needles using a neutral technique (known as Ping Bu Ping Xie) into the Dai mai and Shen mai points, i.e. gall bladder 26 and bladder 62. Imaging was done on a Siemens Magnetom Avanto MR scanner using a head array and body coil. Mainly T1-weighted imaging sequences, as routinely used for patient exams, were used to obtain multi-slice images. In the preliminary experiments only acupuncture needles made of gold showed enough stability in order to be used for further imaging procedures. Using an onion and a banana as an object, further studies showed that the gold needles produced a void defect that corresponds to the tip of the inserted needle, while at the same time an artefactually increased diameter was observed. The in-vivo experiments showed that the Dai mai point was in relation to the abdominal internal oblique muscle. The Shen mai point artefact showed up close to the longus and brevis peroneal tendons at the fibular malleolus. Side effects related to heating or burning were not observed. Improved anatomical recognition was obtained using 3D-volume rendering techniques. Through an adequate choice of acupuncture material (gold needles) as well as of

    The compartment model POSEIDON-R was modified and applied to the Northwestern Pacific and adjacent seas to simulate the transport and fate of radioactivity in the period 1945-2010, and to perform a radiological assessment on the releases of radioactivity due to the Fukushima Dai-ichi accident for the period 2011-2040. The model predicts the dispersion of radioactivity in the water column and in sediments, the transfer of radionuclides throughout the marine food web, and subsequent doses to humans due to the consumption of marine products. A generic predictive dynamic food-chain model is used instead of the biological concentration factor (BCF) approach. The radionuclide uptake model for fish has as a central feature the accumulation of radionuclides in the target tissue. The three layer structure of the water column makes it possible to describe the vertical structure of radioactivity in deep waters. In total 175 compartments cover the Northwestern Pacific, the East China and Yellow Seas and the East/Japan Sea. The model was validated from (137)Cs data for the period 1945-2010. Calculated concentrations of (137)Cs in water, bottom sediments and marine organisms in the coastal compartment, before and after the accident, are in close agreement with measurements from the Japanese agencies. The agreement for water is achieved when an additional continuous flux of 3.6 TBq y(-1) is used for underground leakage of contaminated water from the Fukushima Dai-ichi NPP, during the three years following the accident. The dynamic food web model predicts that due to the delay of the transfer throughout the food web, the concentration of (137)Cs for piscivorous fishes returns to background level only in 2016. For the year 2011, the calculated individual dose rate for Fukushima Prefecture due to consumption of fishery products is 3.6 μSv y(-1). Following the Fukushima Dai-ichi accident the collective dose due to ingestion of marine products for Japan increased in 2011 by a

    Kashiwa city is located in the northwest part of Chiba prefecture in the metropolitan area of Tokyo, Japan. It is about 200 km to the south of the TEPCO Fukushima Dai-ichi Nuclear Power Plant. The population of the city was 404,252 as of April 1, 2012, and its area is 114.9 km 2 . The local government has officially surveyed the environmental radiation status after the disaster in response to numerous requests from its citizens. The radiation surveillance in this area has been conducted by the radiation protection specialists. The two main goals of the surveillance are (1) to measure the ambient radiation dose (microsieverts per hour) at all the school yards, public parks, and representative measuring points selected by the local government, and (2) to measure the specific radioactivity (becquerels per kilogram) of drinking water and local food items. These data have been reported on the city website as well as in a bi-monthly report in the public relations magazine of the local government. This report presents the background status and technical information on the related activities, and the measured environmental radiation data. The ambient radiation dose in the city has been surveyed since June, 2011. In the 1st period of the surveillance (from May to August, 2011) at a total of 210 survey points, the highest value of the ambient radiation dose was 0.65 μSv h -1 at the height of 1 m from the ground, the lowest was 0.08 μSv h -1 , and the average was 0.25 μSv h -1 . These values include the natural background dose rate detected by the survey-meters. In the 4th period, the latest data around school yards were 0.30 at maximum, 0.04 at minimum, and 0.12 μSv h -1 on average. The ambient dose at 41 of 61 school yards and 47 of 635 parks has been reduced under the decontamination project by the local government, so far. The net dose reduction rate, without the natural background dose, was from 30%-80% in the school yards and the parks. Decontamination activity

    The University of Tokyo campuses are primarily located in the metropolitan area of Tokyo, Japan. The three main university campuses are the Hongo campus and the Komaba campus, located in the mideastern part of Tokyo prefecture, and the Kashiwa campus, located in the north western part of Chiba prefecture. The distance between the Fukushima Dai-ichi nuclear power plant and these three campuses ranges from ∼200 to ∼250 km. Immediately after the nuclear disaster, the university organized a special correspondence team to survey the environmental radiation status for the university. The team consists of about 20 members, including mostly radiation protection specialists or technical experts of the university specialized in radiation measurements. This project is not research-oriented; rather, the purpose is to provide, in the absence of related information, the actual data on environmental radiation immediately after the accident. This information is provided both to the members of the university community and to the public. The two primary measured quantities are (1) the ambient radiation dose (microsieverts per hour) and (2) the specific radioactivity (becquerels per kilogram) of soil around the surface of a ground, which is used to indicate the level of contamination. The ambient dose data were reported every day on the web site and the portal site magazine of the university, and soil contamination data were reported occasionally. This report provides the background status and technical information on the related activities. In addition, it documents the measured environmental radiation data. Temporal variation of the ambient radiation dose rate had been officially surveyed since the morning of March 15, 2011, at the selected representative locations on the campus sites. In addition, maps were drawn that showed the distribution area of the ambient dose rate of three campuses. The first peak dose of 0.72 μSv h"-"1 was observed at ∼2:30 pm on May 15, 2011, in

    Full Text Available The article deals with a case from the creative history of Leo Tolstoy’s The Circle of Reading (1908, when Tolstoy included the revised story of Guy de Maupassant’s Le Port under the title “Sisters” in the second edition of the book. The author proves that the reason for Tolstoy’s decision was his polemic with “saninstvo” as one of the most fashionable ethical trends of the first decade of the 1900s. The key component of Sanin’s behavior and hedonistic philosophy in Mikhail Artsybashev’s novel was incest. Maupassant’s novella is based on the same plot. On the basis of Tolstoy’s nonfictional texts of the 1890s, including the treatise What Is Art? (1898, the article reconstructs the writer’s view on the forms and boundaries of the representation of incest in Richard Wagner’s operas and in Friedrich Nietzsche’s philosophy, with which Tolstoy also polemicized and in connection with which he stated the ethical potential of art and its permissiveness. From this perspective, Tolstoy’s reaction to Artsybashev’s novel, combining the motives of incest and extreme individualism, turns out to be a new phase of the old dispute. Tolstoy included the story “Sisters” in the second edition of The Circle of Reading as a response to the philosophy of “saninstvo.” Thus, Tolstoy’s collection of wise thoughts can be considered not only as didactic, but also as a polemical text, and deeply rooted in the ideological context of the 1890s‒1900s.

The conference was the seventh in a series and included a stellar array of invited speakers, compelling panel discussions, a student poster competition, a daylong Doctoral Consortium, a session featuring a choice of attractions unique to Washington, D.C., a gala banquet and dance, and many exciting networking opportunities. The conference created a welcoming environment for STEM students, especially underrepresented minority and female students, who were provided the highest quality of learning, networking, and social experiences to empower their educational experience and enhance their ability to succeed with a rigorous STEM degree. The networking and mentoring opportunities available at the conference were also designed to empower students to succeed in STEM careers and ultimately serve in leadership in industry and the professoriate. A key step in attracting underrepresented students into STEM fields and paving the way for their success in influential positions is to create a nurturing and supportive network and community for them to rely upon. It is also critical to educate leaders in corporations, government and academia about the benefits to be gained from increasing the percentage of STEM professionals from underrepresented groups. To this end, The Tapia Conference serves both functions, as it connects STEM students with STEM professionals, leaders, and academics who share the vision of a STEM workforce and community that is truly representative of the community in which we live.

    Ross [Ross PJ. Modeling soil water and solute transport - fast, simplified numerical solutions. Agron J 2003;95:1352-61] developed a fast, simplified method for solving Richards' equation. This non-iterative 1D approach, using Brooks and Corey [Brooks RH, Corey AT. Hydraulic properties of porous media. Hydrol. papers, Colorado St. Univ., Fort Collins: 1964] hydraulic functions, allows a significant reduction in computing time while maintaining the accuracy of the results. The first aim of this work is to confirm these results in a more extensive set of problems, including those that would lead to serious numerical difficulties for the standard numerical method. The second aim is to validate a generalisation of the Ross method to other mathematical representations of hydraulic functions. The Ross method is compared with the standard finite element model, Hydrus-1D [Simunek J, Sejna M, Van Genuchten MTh. The HYDRUS-1D and HYDRUS-2D codes for estimating unsaturated soil hydraulic and solutes transport parameters. Agron Abstr 357; 1999]. Computing time, accuracy of results and robustness of numerical schemes are monitored in 1D simulations involving different types of homogeneous soils, grids and hydrological conditions. The Ross method associated with modified Van Genuchten hydraulic functions [Vogel T, Cislerova M. On the reliability of unsaturated hydraulic conductivity calculated from the moisture retention curve. Transport Porous Media 1988:3:1-15] proves in every tested scenario to be more robust numerically, and the compromise of computing time/accuracy is seen to be particularly improved on coarse grids. Ross method run from 1.25 to 14 times faster than Hydrus-1D. (authors)

  6. ‘By Force of Participation and Conjunction in Him’: John Jewel and Richard Hooker on Union with Christ

    Full Text Available The author of a Christian Letter cited a passage from John Jewel’s A Reply to Harding’s Answer in which the first major apologist of the Elizabethan Settlement spoke of the role of faith and the sacraments in union with Christ. Andrew Willet, the likely author of this work, quoted it against Richard Hooker in order to show how the latter contravened the sacramental theology of the national Church as interpreted by Jewel as one of the foremost expositors of its doctrine. Jewel, however, in his Reply to Harding’s Answer, enumerates four means of the Christian’s union with Christ: the Incarnation, faith, baptism, and the Eucharist-a fact overlooked in A Christian Letter by its author in his endeavor to impeach Hooker’s orthodoxy. Proceeding from the observation that both Jewel and Hooker believed that the locus of Christian salvation is union with Christ, this essay compares the two divines’ respective views of this union by examining the manner in which they understand the role of each of these means forming and maintaining this union. On the basis of this comparison, the essay argues that A Christian Letter misrepresented Jewel’s position and that Hooker’s view of union with Christ was essentially the same as the late bishop of Salisbury’s, notwithstanding some differences in detail and emphases. The article concludes with the opinion that Hooker represents continuity of a particular soteriological emphasis in the Elizabethan Church that can possibly be traced back to Jewel as a representative of the Reformed tradition stressing this doctrine.

    This article describes occupational health measures for workers involved in decontamination of radioactive material discharged around Fukushima Dai-ichi Nuclear Power Plant after the explosions in 2011. Decontamination is performed by removing radioactive particles (mainly cesium) from surfaces of soil, grass and trees, and buildings. Measurement of radiation doses is necessary to reduce exposure, and to determine whether workers can work below dose limits. Protective equipment for decontamination is determined based on the concentration of radiation in contaminated soil and the exposure to dust. Health examinations by physicians are mandated for decontamination workers upon hiring and every 6 months. While there is no possibility of acute radiation injury from decontamination, workers may be anxious about the unclear effects of chronic low level radiation exposure on health. Measures to protect the decontamination workers are the top priority.

    The most important contributions of Einstein involve 5 fields of physics : the existence of quanta (light quanta, stimulated radiation emission and Bose-Einstein condensation), relativity, fluctuations (Brownian motion and thermodynamical fluctuations), the basis of quantum physics and cosmology (cosmological constant and the expansion of the universe). Diverse and renowned physicists have appreciated the development of modern physics from Einstein's ideas to the knowledge of today. This book is a collective book that gathers their work under 7 chapters: 1) 1905, a new beginning; 2) from the Einstein, Podolsky and Rosen's article to quantum information (cryptography and quantum computers); 3) the Bose-Einstein condensation in gases; 4) from stimulated emission to the today's lasers; 5) Brownian motion and the fluctuation-dissipation theory; 6) general relativity; and 7) cosmology.

    Radiocaesium ((134)Cs and (137)Cs) release following the accident at the Fukushima Dai-ichi Nuclear Power Plant, belonging to the Tokyo Electric Power Company caused severe contamination of new tea plant (Camellia sinensis (L.)) shoots by radiocaesium in many prefectures in eastern Japan. Because tea plants are perennial crops, there is the fear that the contamination might last for a long time. The objectives of this study were to reveal time series changes in the distribution of radiocaesium in tea plants after radioactive fallout and to evaluate the effect of pruning on reduction of radiocaesium concentrations in new shoots growing next year. The experimental tea field was located in Shizuoka, Japan, approximately 400 km away from the Fukushima Dai-ichi Nuclear Power Plant in a southwest direction. Time series changes in radiocaesium concentrations in unrefined tea, a tea product primarily produced for making Japanese green tea, from May 2011 to June 2013 and distribution of radiocaesium in tea plants from May 2011 to May 2012 were monitored. The radiocaesium concentrations in unrefined tea exponentially decreased; the effective half-lives for (134)Cs and (137)Cs were 0.30 and 0.36 y during the first 2 y after the accident, respectively. With time, the highest concentrations of (137)Cs moved from the upper to the lower parts of plants. Medium pruning 2-3 months after the accident reduced the concentration of (137)Cs in new shoots harvested in the first crop season of the following year by 56% compared with unpruned tea plants; thus, pruning is an effective measure for reducing radiocaesium concentration in tea.

    Radioactive nuclides were released in the atmosphere by the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station in March, 2011, and they are detected on the materials that had no artificial radioactive nuclides before the accident. Confronted with this situation, NISA issued a guideline titled 'A guideline regarding treatment of materials in nuclear facilities considering the influence of fallout released from the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station' on March 30, 2012. Nuclear Regulatory Authority refers to applying the existing bylaw until the time to make decision of the updated bylaw. The guideline shows that after judging whether there is the influence of fallout or not, the conventional clearance and NR systems can be used when there is no influence of fallout. On the other hand, the special treatment is required when it is judged that there is the influence. This report describes a specific example of measuring method to evaluate the influence of fallout, in case of surface contamination. This report focused surface contamination of flat object as target. Preliminary investigation shows that the distribution of surface contamination due to fallout is near to lognormal distribution. Therefore, the sampling measurement can be adopted. The average surface contamination of target is decided from sampling data by using 90% upper confidence limit of Chebyshev inequality. Also, the minimum sampling number is decided. The evaluation of the influence of fallout is judged from the result of surface contamination measurement, weight of target and surface area of target.

    This paper examines the social thought of University of Wisconsin professors Richard T. Ely, John R. Commons, and Edward A. Ross during World War I. Like many of their fellow scholars, these three were actively involved in the pro-war effort. Although their support for the war was strongly conditioned by personal and occupational considerations, the impact of their wartime service was not restricted to those realms. Their social thought, which they impressed into service explaining and justifying the war, was itself altered in subtle and sometimes surprising ways by the forceful positions they took on the political, economic, and racial significance of the conflict.

Mais especificamente, o artigo explora a proposta rortyana de substituição da noção de verdade pela de justificação, assinalando-se suas consequências para pretensões de verdade, objetividade e universalismo, presentes em diversas linhas da teoria política. Nesse veio, o artigo discute as eventuais implicações relativistas das teses rortyanas, chegando-se, por essa rota, às ideias de contingência, imaginação e persuasão, núcleos conceituais vitais à reflexão em tela. Um breve contraste com posições de autores como Habermas e Rawls, caros ao próprio Rorty, é esboçado no propósito de tornar mais clara a especificidade da abordagem rortyana da política.

    The results of γ analyses of soil samples obtained from 50 locations in Fukushima prefecture on April 20, 2011, revealed the presence of a spectrum of radionuclides resulted from the accident of the Fukushima Dai-ichi nuclear power plant (FDNPP). The sum γ radioactivity concentration ranged in more than 3 orders of magnitude, depending on the sampling locations. The contamination of soils in the northwest of the FDNPP was considerable. The 131 I/ 137 Cs activity ratios of the soil samples plotted as a function of the distance from the F1 NPPs exhibited three distinctive patterns. Such patterns would reflect not only the different deposition behaviors of these radionuclides, but also on the conditions of associated release events such as temperature and compositions and physicochemical forms of released radionuclides. The 136 Cs/ 137 Cs activity ratio, on the other hand, was considered to only reflect the difference in isotopic compositions of source materials. Two locations close to the NPP in the northwest direction were found to be depleted in short-lived 136 Cs. This likely suggested the presence of distinct sources with different 136 Cs/ 137 Cs isotopic ratios, although their details were unknown at present. Vertical γ activity profiles of 131 I and 137 Cs were also investigated, using 20–30 cm soil cores in several locations. About 70% or more of the radionuclides were present in the uppermost 2-cm regions. It was found that the profiles of 131 I/ 137 Cs activity ratios showed maxima in the 2–4 cm regions, suggesting slightly larger migration of the former nuclide. - Highlights: ► We report the results of γ analyses of soil samples around Fukushima Dai-ichi NPPs. ► The contamination of soils in the northwest of the power plant was considerable. ► The 131 I/ 137 Cs activity ratios exhibited three distinctive patterns. ► Most of 131 I and 137 Cs were present in the uppermost 2-cm regions of soil.

    Full Text Available The real cause of Soeharto’s fall from the Indonesian presidency remains a mystery. Richard Mann (1998 launched three significant rhetorical questions: (a Was President Soeharto toppled by student demonstrators and people’s power? (b Was he brought down by the withdrawal of support from the United States? (c Or, was his sudden fall brought about by all of the two plus large doses of Oriental plotting and scheming? This article attempts to analyze Richard Mann’s PSBDS in terms of its macrostructure in order to find out the real cause of Soeharto’s fall. The analysis is substantiated by different resources as linguistic evidences, to justify the validity of the findings. The study revealed a proposition that critical reading is the key to successful comprehension of a text which may include a crosschecking with other resources, a careful identification of the generic structure of a text, and paying attention to how an author positions his or her readers. The article concludes, that in fact, Soeharto resigned from presidency on his own wisdom in order to avoid more bloodshed in Indonesian dreamland.

This synthesis presents a status of the data recently obtained since the previous similar notes of April 12 and May 25. The note presents the detailed activity analysis of several surface soil samples (Iitate Maeda, Namie, Hirono, Fukushima..), a mapping of 137 Cs and 134 Cs cumulated deposits in a 80 km area around the damaged power plant, the evolution of radioactive deposits since March 2011 in different places (Fukushima, Hitachinaka, Saitama, Utsunomiya), the evolution of the 134 Cs+ 137 Cs and 131 I contamination of agriculture food products and of drinking water. The IRSN has detected also a significant contamination of some tea samples imported from the Omaezaki region and intercepted by the French customs. Some information about tea and bamboo shoots cultivation and processing in Japan is added in appendix. (J.S.)

    A strong radioactive contamination of the marine environment close to the damaged Fukushima Dai-ichi power plant has been observed since March 21. The high concentration of some nuclides ( 131 I, 137 Cs, 134 Cs, 136 Cs, 132 Te, 132 I) comes from three possible sources: the liquid effluents from the damaged site, the atmospheric fallouts, and the weathering of contaminated soils. This information note presents and comments the most recent informations gathered by the French institute of radiation protection and nuclear safety (IRSN) since the previous information note from July 11 and devoted to the same topic. It presents the estimation of the relative contribution of each contamination source and the evolution with time of the marine contamination. The mapping of 137 Cs concentrations in surface seawater allows to estimate the amount of total 137 Cs in the marine environment and its evolution with time. 137 Cs and 134 Cs concentrations were measured both in samples of surface coastal sediments and in river fishes and seafood products (mainly fishes and molluscs). Results are reported in graphs showing their evolution with time. (J.S.)

    Objective: To understand the epidemiological characteristics of newly reported HIV infections in Chinese and Burmese residents during 2012-2016 in Dehong Dai and Jingpo Autonomous Prefecture of Yunnan province (Dehong) and to provide evidence for the development of related programs on prevention and control. Methods: All the HIV infections who were newly reported during 2012-2016 in Dehong, were recruited as the study subjects, with epidemiological characteristics of the cases analyzed by using the software SPSS 22.0. Results: A total of 5 692 HIV infections were newly reported between 2012 and 2016 (including 5 592 in this study), in which the Chinese patients accounted for 43.3 % (2 419) and the rest 56.7 % (3 173) were Burmese. Differences in age, gender and other social characteristics of these newly reported HIV infections were statistically significant between the Chinese and the Burmese (all p -values Chinese patients but through injecting drug use among the Burmese patients. Conclusions: Epidemiological characteristics of the newly reported HIV infections were different between the Chinese and the Burmese, between 2012 and 2016 in Dehong. Targeted prevention and control programs should be taken.

    The accident at the Fukushima Dai-ichi Nuclear Power Plant (NPP) in March 2011 affected not only the terrestrial environment of Fukushima prefecture and the surrounding area, but also the marine area facing the NPP. Our present study is focused on the concentrations of radionuclides in agricultural products of Fukushima and sea-foods collected off Fukushima after the accident. The regulation value for radiocesium in vegetables, meat and fish was revised from 500 Bq/kg-wet to 100 Bq/kg-wet on 1 April 2012. The overall activity of radiocesium in these products was found to be within the limit of tolerance in respect to Japanese and also international regulations, but there is still radiocesium found at activities greater than this level in edible wild plants, wild mushrooms and game such as boar meat. Although the activities of radionuclides exceeding the regulatory limits were not detected in marine products collected off Fukushima after April 2015, the commercial marine fishery has not received approval in the affected areas except for certain species. We learned from the Fukushima accident that long-term kinetic studies of radionuclides in terrestrial and marine environments is extremely important for prevention of internal contamination, since contamination with radionuclides occurs via the food chain in the environment. © World Health Organisation 2016.

    Full Text Available Wetlands are particularly sensitive environments receiving attention from the natural sciences community due to their wealth of both flora and fauna, and often considered as natural parks. In the Tablas de Daimiel (La Mancha, Central Spain, Digital Airborne Imaging Spectrometer data (DAIS 7915 have been analyzed to map geological processes on areas around the receding wetland which have never been flooded by water in the past. Sediments permanently exposed to the atmosphere dehydrate and oxide, developing different mineralogical associations arranged on planation surfaces. Such planation surfaces are key in the geological knowledge of recent climate change and landscape evolution. Progressive iron oxide/hydroxide rate and decarbonation can be spectrally followed on the Holocene sands framing the current marshy area. Such mineralogical changes are geologically registered on flat surfaces at different heights over the receding shore of the paleolake. Interacting erosion and sedimentation processes are responsible for the development of the flat morphological surfaces with increasing dryness. Maps are built for four different morphological units consisting of planation surfaces following chronologically the receding marsh during the last 2000 years before the present. Interactive spectral responses of mineralogical associations are described on the imagery, field and laboratory spectra.

    Sedimentation and remobilization processes of radiocesium were investigated from time-series observations at nine stations in the coastal area of Ibaraki, 70-110 km south of the Fukushima Dai-ichi Nuclear Power Plant (1FNPP). Sediment samples were collected four times between June 2011 and January 2012, and concentrations of radiocesium as well as sediment properties such as grain size and elemental compositions were analyzed. Cumulative inventory of (137)Cs in sediment (0-10 cm) ranged between 4 × 10(3) and 3 × 10(4) Bq/m(2) as of January 2012. This amount was generally higher at stations nearer 1FNPP and has remained at the same level since August 2011. From these results, it can be inferred that dissolved radiocesium advected southward from the region adjacent to the 1FNPP and was deposited to the sediment of the study area in the early stage after the accident. The incorporation of radiocesium into sediments was almost irreversible, and higher concentrations of (137)Cs were obtained from the finer-grained fraction of sediments. In the northern offshore stations, resuspension of the fine-grained sediments formed a high-turbidity layer 10-20 m above the seabed. These results indicate that radiocesium-enriched fine particles were transported from the coast to offshore regions through the bottom high-turbidity layer.

  17. Knowledge Management Learned from Decommissioning and Environmental Remediation after an Unexpected Radiological Contamination Occurred at Fukushima Dai-ichi NPP Accident

    Full text: The Fukushima Dai-ichi Nuclear Power Plant (NPP) Accident resulted in severe damage of cores in units 1 to 3, and subsequently entailed not only contamination of facility but also widely-spread radiological contamination in environment due to the release of radioactive nuclides. Decommissioning activities will require at least 30–40 years with various stages of operation, such as contaminated water treatment, decontamination of reactor buildings, retrieval of spent fuel (SF) from SF pools, inspection of primary containment vessel (PCV) and reactor pressure vessel (RPV), and retrieval and further management of damaged fuel and melted debris. Especially, a water injection for core cooling is a pressing issue to stabilize the melted debris, which leads to produce a large amount of contaminated water. Environmental remediation is a crucial issue to return a normal life for local residents. On-site cleaning and off-site remediation produce various kinds and enormous amount of contaminated material with low to high radioactivity. Knowledge management of on-site and off-site issues over generation are critical to achieve the cleaning and remediation requiring a couple of decades. In addition, knowledge obtained through a long term-operation should be shared globally. (author

    Soil deposition density maps of gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident were constructed on the basis of results from large-scale soil sampling. In total 10,915 soil samples were collected at 2168 locations. Gamma rays emitted from the samples were measured by Ge detectors and analyzed using a reliable unified method. The determined radioactivity was corrected to that of June 14, 2011 by considering the intrinsic decay constant of each nuclide. Finally the deposition maps were created for (134)Cs, (137)Cs, (131)I, (129m)Te and (110m)Ag. The radioactivity ratio of (134)Cs-(137)Cs was almost constant at 0.91 regardless of the locations of soil sampling. The radioactivity ratios of (131)I and (129m)Te-(137)Cs were relatively high in the regions south of the Fukushima NPP site. Effective doses for 50 y after the accident were evaluated for external and inhalation exposures due to the observed radioactive nuclides. The radiation doses from radioactive cesium were found to be much higher than those from the other radioactive nuclides. Copyright © 2014 The Authors. Published by Elsevier Ltd..

    The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident resulted in extensive radioactive contamination of the environment via deposited radionuclides such as radiocesium and 131 I. Evaluating the extent and level of environmental contamination is critical to protecting citizens in affected areas and to planning decontamination efforts. However, a standardized soil sampling protocol is needed in such emergencies to facilitate the collection of large, tractable samples for measuring gamma-emitting radionuclides. In this study, we developed an emergency soil sampling protocol based on preliminary sampling from the FDNPP accident-affected area. We also present the results of a preliminary experiment aimed to evaluate the influence of various procedures (e.g., mixing, number of samples) on measured radioactivity. Results show that sample mixing strongly affects measured radioactivity in soil samples. Furthermore, for homogenization, shaking the plastic sample container at least 150 times or disaggregating soil by hand-rolling in a disposable plastic bag is required. Finally, we determined that five soil samples within a 3 m × 3-m area are the minimum number required for reducing measurement uncertainty in the emergency soil sampling protocol proposed here. - Highlights: • Emergency soil sampling protocol was proposed for nuclear hazards. • Various sampling procedures were tested and evaluated in Fukushima area. • Soil sample mixing procedure was of key importance for measured radioactivity. • Minimum number of sampling was determined for reducing measurement uncertainty

    The Great East Japan Earthquake in March 2011 destroyed the Fukushima Dai-ichi Nuclear Power Plant (FNPP) and almost all residents in a 20 km radius from the plant eventually evacuated. FNPP reactors were stabilised in December 2011; some evacuees decided to return to their hometowns, and the other evacuees remained. Efforts were made to identify the determinants that affect the decision to return home in order to promote recovery of the surrounding area of FNPP. Seventy one residents who had not returned to hometown and 56 residents who had returned were selected. Logistic regression analysis adjusted for confounding factors showed that being female [odds ratio (OR): 2.43, p=50.03], living in areas with relatively higher ambient doses (OR: 3.60, p=50.01) and expressing anxiety over radiation exposure (OR: 8.91, p < 0.01) were independently associated with decisions not to return. Results of this study suggest the importance of active participation by scientists and local authorities in communicating the risk to the general population involved in returning home. (authors)

    Radiocesium ((137)Cs) transfer to plants immediately after the Fukushima Dai-ichi Nuclear Power Plant accident was investigated by collecting newly emerged leaf and soil samples between May 2011 and November 2012 from 20 sites in the Fukushima prefecture. Radiocesium concentrations in leaf and soil samples were measured to calculate concentration ratios (CR). Woody plants exhibited high CR values because (137)Cs deposited on stems and/or leaves were transferred to newly emerging tissues. The CR values in 2012 declined as compared to that in 2011. Exchangeable (137)Cs rates in soil (extraction rate) samples were measured at five sites. These rates decreased at four sites in 2012 and depended on environmental conditions and soil type. Both CR values and extraction rates decreased in 2012. However, CR values reflected the changes in extraction rates and characteristics of each species. Amaranthaceae, Chenopodiaceae, and Polygonaceae, which had been identified as Cs accumulators, presented no clear (137)Cs accumulation ability. In 2012, the perennial plant Houttuynia cordata and deciduous trees Chengiopanax sciadophylloides and Acer crataegifolium displayed high CR values, indicating that these species are (137)Cs accumulators and may be considered as potential species for phytoremediation.

    We investigated the deposition and depth distributions of radiocesium in the Takizawa Research Forest, Iwate Prefecture, in order to understand the behavior of radionuclides released from the Fukushima Dai-ichi Nuclear Power Plant. The deposition distribution and vertical depth distribution of radiocesium in the soil were compared between topographically distinct parts of the forest where two different tree species grow. The results for all investigated locations show that almost 85% of the radiocesium has accumulated in the region of soil from the topmost organic layer to a soil depth of 0-4 cm. However, no activity was detected at depths greater than 20 cm. Analysis of the radiocesium deposition patterns in forest locations dominated by either coniferous or deciduous tree species suggests that radiocesium was sequestered and retained in higher concentrations in coniferous areas. The deposition data showed large spatial variability, reflecting the differences in tree species and topography. The variations in the measured 137 Cs concentrations reflected the variability in the characteristics of the forest floor environment and the heterogeneity of the initial ground-deposition of the Fukushima fallout. Sequential extraction experiments showed that most of the 137 Cs was present in an un-exchangeable form with weak mobility. Nevertheless, the post-vertical distribution of 137 Cs is expected to be governed by the percentage of exchangeable 137 Cs in the organic layer and the organic-rich upper soil horizons.

    A series of car-borne surveys using the Kyoto University RAdiation MApping (KURAMA) and KURAMA-II survey systems has been conducted over a wide area in eastern Japan since June 2011 to evaluate the distribution of air dose rates around the Fukushima Dai-ichi Nuclear Power Plant and to evaluate the time-dependent trend of decrease in air dose rates. An automated data processing system for the KURAMA-II system was established, which enabled rapid analysis of large amounts of data obtained using about 100 KURAMA-II units. The initial data used for evaluating the migration status of radioactive cesium were obtained in the first survey, followed by other car-borne surveys conducted over more extensive and wider measurement ranges. By comparing the measured air dose rates obtained in each survey (until December 2012), the decreasing trend of air dose rates measured through car-borne surveys was found to be more pronounced than those expected on the basis of the physical decay of radioactive cesium and of the air dose rates measured using NaI (Tl) survey meters in the areas surrounding the roadways. In addition, it was found that the extent of decrease in air dose rates depended on land use, wherein it decreased faster for land used as building sites than for forested areas.

    This paper describes an investigation into the impact of different meteorological data sets and different wet scavenging coefficients on the model predictions of radionuclide deposits following the accident at the Fukushima Dai-ichi nuclear power plant in March 2011. Three separate operational meteorological data sets, the UK Met Office global meteorology, the ECMWF global meteorology and the Japan Meteorological Agency (JMA) mesoscale meteorology as well as radar rainfall analyses from JMA were all used as inputs to the UK Met Office's dispersion model NAME (the Numerical Atmospheric-dispersion Modelling Environment). The model predictions of Caesium-137 deposits based on these meteorological models all showed good agreement with observations of deposits made in eastern Japan with correlation coefficients ranging from 0.44 to 0.80. Unexpectedly the NAME run using radar rainfall data had a lower correlation coefficient (R = 0.66), when compared to observations, than the run using the JMA mesoscale model rainfall (R = 0.76) or the run using ECMWF met data (R = 0.80). Additionally the impact of modifying the wet scavenging coefficients used in the parameterisation of wet deposition was investigated. The results showed that modifying the scavenging parameters had a similar impact to modifying the driving meteorology on the rank calculated from comparing the modelled and observed deposition

  6. Kalman filters for assimilating near-surface observations into the Richards equation - Part 2: A dual filter approach for simultaneous retrieval of states and parameters

    2014-07-01

    This study presents a dual Kalman filter (DSUKF - dual standard-unscented Kalman filter) for retrieving states and parameters controlling the soil water dynamics in a homogeneous soil column, by assimilating near-surface state observations. The DSUKF couples a standard Kalman filter for retrieving the states of a linear solver of the Richards equation, and an unscented Kalman filter for retrieving the parameters of the soil hydraulic functions, which are defined according to the van Genuchten-Mualem closed-form model. The accuracy and the computational expense of the DSUKF are compared with those of the dual ensemble Kalman filter (DEnKF) implemented with a nonlinear solver of the Richards equation. Both the DSUKF and the DEnKF are applied with two alternative state-space formulations of the Richards equation, respectively differentiated by the type of variable employed for representing the states: either the soil water content (θ) or the soil water matric pressure head (h). The comparison analyses are conducted with reference to synthetic time series of the true states, noise corrupted observations, and synthetic time series of the meteorological forcing. The performance of the retrieval algorithms are examined accounting for the effects exerted on the output by the input parameters, the observation depth and assimilation frequency, as well as by the relationship between retrieved states and assimilated variables. The uncertainty of the states retrieved with DSUKF is considerably reduced, for any initial wrong parameterization, with similar accuracy but less computational effort than the DEnKF, when this is implemented with ensembles of 25 members. For ensemble sizes of the same order of those involved in the DSUKF, the DEnKF fails to provide reliable posterior estimates of states and parameters. The retrieval performance of the soil hydraulic parameters is strongly affected by several factors, such as the initial guess of the unknown parameters, the wet or dry

    2013-09-01

    In this article, we propose a new exact and grid-free numerical scheme for computing solutions associated with an hybrid traffic flow model based on the Lighthill-Whitham-Richards (LWR) partial differential equation, for a class of fundamental diagrams. In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a constant acceleration otherwise. We first propose a mathematical definition of the solution as a minimization problem. We use this formulation to build a grid-free solution method for this model based on the minimization of component function. We then derive these component functions analytically for triangular fundamental diagrams, which are commonly used to model traffic flow. We also show that the proposed computational method can handle fixed or moving bottlenecks. A toolbox implementation of the resulting algorithm is briefly discussed, and posted at https://dl.dropbox.com/u/1318701/Toolbox.zip. © 2013 Elsevier Ltd.

    During the years 1714 to 1721, Richard Bradley, who was later to become the first Professor of Botany at Cambridge University, proposed a unified, unique, living agent theory of the cause of infectious diseases of plants and animals and the plague of humans. Bradley's agents included microscopic organisms, revealed by the studies of Robert Hooke and Antony van Leeuwenhoek. His theory derived from his experimental studies of plants and their diseases and from microscopic observation of animalcules in different naturally occurring and artificial environments. He concluded that there was a microscopic world of "insects" that lived and reproduced under the appropriate conditions, and that infectious diseases of plants were caused by such "insects." Since there are structural and functional similarities between plants and animals, Bradley concluded that microscopic organisms caused human and animal infectious diseases as well. However, his living agent cause of infectious diseases was not accepted by the contemporary scientific society.

    In this article, we propose a new grid-free and exact solution method for computing solutions associated with an hybrid traffic flow model based on the Lighthill- Whitham-Richards (LWR) partial differential equation. In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a fixed acceleration otherwise. We first present a grid-free solution method for the LWR equation based on the minimization of component functions. We then show that this solution method can be extended to compute the solutions to the hybrid model by proper modification of the component functions, for any concave fundamental diagram. We derive these functions analytically for the specific case of a triangular fundamental diagram. We also show that the proposed computational method can handle fixed or moving bottlenecks.

    Richard L. Reece, MD, interviewed John Danaher, MD, MBA, on August 16, 2000, to discuss how his new company is preparing for the perfect storm--the looming convergence of demanding consumers, defined contributions, and Internet-based health plans. He describes how his firm is putting financial and clinical tools in the hands of consumers and physicians, so consumers can be more enlightened in their health care choices. Danaher says, "We're not about buying goods and services online. We are transforming the way consumers buy health care and seek insurance. We're trying to be a 401 k where people get on, knowing their risk profile and return horizons. We aim to motivate consumers to be proactive in making health care choices. How do we make consumers responsible and motivated enough to take control of managing their health care costs? How well we articulate this call to consumer action will be the key to our success."

  13. Imitating Jesus, yes – but which Jesus? A critical engagement with the ethics of Richard Burridge in Imitating Jesus: An inclusive approach to New Testament ethics (2007

    Directory of Open Access Journals (Sweden)

    Jonathan A. Draper

    2009-08-01

    Full Text Available This paper examines the attempt by Richard Burridge in his recent book, Imitating Jesus: An inclusive approach to New Testament ethics (2007, to build an engaged Christian ethics starting with the historical Jesus but taking full account of the insights into the perspectives of the four gospels in their own right, based on their genre as Greek bioi. While Burridge’s approach is applauded and regarded as a major step forward, it is critiqued here on his selectivity in his presentation of the results of two decades of research into the Jesus of history. Burridge’s selection of the South African experience in the struggle against apartheid as his ‘test case’ is also questioned, since the issues in such struggles for justice appear more straightforward to outsiders than they do to insiders and his analysis raises more questions than it answers.

    Japanese herbal medicine, also known as Kampo, is used for various diseases in Japan. One of those medicines, Dai-Kenchu-To (DKT), is considered clinically effective for adhesive bowel obstruction and chronic constipation. Although scientific evidence of DKT to improve adhesive bowel obstruction was shown in several previous reports, mechanism of DKT to improve constipation remains unknown. Our aim was to study the effect of intragastric DKT on colonic motility and defecation, and the involvement of various receptors in DKT-induced colonic contractions. Five beagle dogs were instructed with serosal strain-gauge force transducers to measure circular muscle activity at the proximal, middle, and distal colon. Dogs are suitable for a present study to administer the drugs repeatedly to the same individual and look at its effect on colonic motility. We studied the effects of DKT (2.5 or 5 g) administered into the stomach on colonic motility. Muscarinic receptor antagonist atropine, nicotinic receptor antagonist hexamthonium, or 5-hydroxytryptamine-3 receptor antagonist ondansetron was injected intravenously 10 min before DKT administration. Capsazepine, an antagonist to transient receptor potential cation channel subfamily V member 1 (TRPV1), was administered into the stomach 5 min before DKT administration. Intragastric DKT (2.5 or 5 g) induced colonic contractions within 10 min after administration but did not induce defecation. Pretreatment with atropine, hexamthonium, ondansetron, or capsazepine inhibited DKT-induced colonic contractions. These results indicate that orally administered DKT stimulates colonic motility via TRPV1, muscarinic, nicotinic, and 5-hydroxytryptamine-3 receptors, thereby providing scientific support for the efficacy of oral DKT in chronic constipation.

    Full Text Available Surface seawater 134Cs and 137Cs samples were collected in the central and western North Pacific Ocean during the 2 yr after the Fukushima Dai-ichi Nuclear Power Plant accident to monitor dispersion patterns of these radioisotopes towards the Hawaiian Islands. In the absence of other recent sources and due to its short half-life, only those parts of the Pacific Ocean would have detectable 134Cs values that were impacted by Fukushima releases. Between March and May 2011, 134Cs was not detected around the Hawaiian Islands and Guam. Here, most 137Cs activities (1.2–1.5 Bq m–3 were in the range of expected preexisting levels. Some samples north of the Hawaiian Islands (1.6–1.8 Bq m–3 were elevated above the 23-month baseline established in surface seawater in Hawaii indicating that those might carry atmospheric fallout. The 23-month time-series analysis of surface seawater from Hawaii did not reveal any seasonal variability or trends, with an average activity of 1.46 ± 0.06 Bq m–3 (Station Aloha, 18 values. In contrast, samples collected between Japan and Hawaii contained 134Cs activities in the range of 1–4 Bq m–3, and 137Cs levels were about 2–3 times above the preexisting activities. We found that the southern boundary of the Kuroshio and Kuroshio extension currents represented a boundary for radiation dispersion with higher activities detected within and north of the major currents. The radiation plume has not been detected over the past 2 yr at the main Hawaiian Islands due to the transport patterns across the Kuroshio and Kuroshio extension currents.

    Estimations of radiocesium input and output concerning the forest floor within a mountain forest region have been conducted in the north and central part of the Abukuma Mountains of Fukushima, northeast Japan, after a 2–3 year period following the TEPCO Fukushima Dai-ichi nuclear power plant accident. The radiocesium input and output associated with surface washoff, throughfall, stemflow, and litterfall processes at experimental plots installed on the forest floor of evergreen Japanese cedars and deciduous Konara oaks have been monitored. Despite the high output potential in the mountainous forest of Fukushima, the results at both monitoring locations show the radiocesium input to be 4–50 times higher than the output during the summer monsoon in Fukushima. These results indicate that the radiocesium tends to be preserved in the forest ecosystem due to extremely low output ratios (0.05%–0.19%). Thus, the associated fluxes throughout the circulation process are key issues for the projecting the environmental fate of the radiocesium levels, along with the subsequent reconstruction of life emphasized within the setting. - Highlights: • Input and output budgets of radiocesium in the mountainous forest of Fukushima were investigated in 2013 and 2014. • "1"3"7Cs outputs were 4–50 times higher than the "1"3"7Cs outputs during the monsoons. • The proportion of "1"3"7Cs output to radiocesium inventories was in the range of 0.05%–0.19% during the monsoons. • Radiocesium tends to be preserved in the forest ecosystem due to extremely low output ratios. • The forest floor seems to be a sink of radiocesium contamination than a source for the other ecosystems.

    Radioactive cesium ( 134 Cs and 137 Cs) concentrations in invertebrates of benthic food web (10 taxonomic classes with 46 identified families) collected from wide areas off Fukushima Prefecture (3–500 m depth) were inspected from July 2011, four months after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, to August 2013 to elucidate time-series trends among taxa and areas. Cesium-137 was detected in seven classes (77% of 592 specimens). Higher 137 Cs concentrations within detected data were often found in areas near or south of the FDNPP, which is consistent with the reported spatial distribution of 137 Cs concentrations in highly contaminated seawater and sediments after the FDNPP accident. Overall 137 Cs concentrations in invertebrates, the maxima of which (290 Bq kg −1 -wet in the sea urchin Glyptocidaris crenularis) were lower than in many demersal fishes, had decreased exponentially with time, and exhibited taxon-specific decreasing trends. Concentrations in Bivalvia and Gastropoda decreased clearly with respective ecological half-lives of 188 d and 102 d. In contrast, decreasing trends in Malacostraca and Polychaeta were more gradual, with longer respective ecological half-lives of 208 d and 487 d. Echinoidea showed no consistent trend, presumably because of effects of contaminated sediments taken into their digestive tract. Comparison of 137 Cs concentrations in the invertebrates and those in seawater and sediments suggest that contaminated sediments are the major source of continuing contamination in benthic invertebrates, especially in Malacostraca and Polychaeta. - Highlights: • Radioactive cesium was measured in benthic invertebrates collected off Fukushima. • Results show taxon-specific and area-specific decreases in ecological half-lives. • Reasonable depuration of 137 Cs concentration was found in Bivalvia and Gastropoda. • Slow depuration was observed in Polychaeta and Malacostraca. • Sediments are expected to be the major

    Full text: This keynote speech will give an overview of NEA Activities to Enhance Global Nuclear Safety both those core to its work and those that have been initiated after the Fukushima Accident. In particular it will highlight the outcomes of the recently published “NEA report on the Fukushima Daiichi Nuclear Power Plant Accident”. The speech will specifically point out those lessons learnt related to Defence in Depth, and how those were fed into the NEA’s one day workshop on “Challenges and Enhancements to DiD in light of the Fukushima Dai-ichi Accident”, that took place on 5th June 2013. A workshop that brought together the member countries represented on the NEA’s three major standing committees for safety to not only discuss the lessons learnt from the accident but also what the NEA members considered could be done to enhance the understanding and implementation of defence in depth within nuclear safety. Members of these three standing committees, the Committee for Nuclear Regulatory Activities (CNRA), The Committee for Safety of Nuclear Installations (CSNI) and the Committee on Radiation Protection and Public Health (CRPPH) represent a considerable body of knowledge on the application of DiD within the countries using nuclear energy. The outcome of the workshop was the identification of a number of key tasks that NEA would take forward to assist in harmonising and enhancing globally the implementation of the DiD philosophy. The speech will in addition detail how the discussions ranged across the whole of the nuclear safety framework, what conclusions were derived and the process the NEA followed to incorporate those tasks within its future programme of work either by enhancing current activities or creating new ones.

    Soil sampling was carried out at an early stage of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. Samples were taken from areas around FDNPP, at four locations northwest of FDNPP, at four schools and in four cities, including Fukushima City. Radioactive contaminants in soil samples were identified and measured by using a Ge detector and included 129m Te, 129 Te, 131 I, 132 Te, 132 I, 134 Cs, 136 Cs, 137 Cs, 140 Ba and 140 La. The highest soil depositions were measured to the northwest of FDNPP. From this soil deposition data, variations in dose rates over time and the cumulative external doses at the locations for 3 months and 1 y after deposition were estimated. At locations northwest of FDNPP, the external dose rate at 3 months after deposition was 4.8–98 μSv/h and the cumulative dose for 1 y was 51 to 1.0 × 10 3 mSv; the highest values were at Futaba Yamada. At the four schools, which were used as evacuation shelters, and in the four urban cities, the external dose rate at 3 months after deposition ranged from 0.03 to 3.8 μSv/h and the cumulative doses for 1 y ranged from 3 to 40 mSv. The cumulative dose at Fukushima Niihama Park was estimated as the highest in the four cities. The estimated external dose rates and cumulative doses show that careful countermeasures and remediation will be needed as a result of the accident, and detailed measurements of radionuclide deposition densities in soil will be important input data to conduct these activities.

    Following a huge earthquake and tsunami in Eastern Japan on 11 March, 2011, the accident in Fukushima Dai-ichi Nuclear Power Plant (FDNPP) occurred to emit a large amount of artificial radionuclides to the environment. Soon after the FDNPP accident, many Japanese researchers, as well as researchers in other countries, started monitoring radionuclides in various environmental fields and/or model calculations to understand extent and magnitude of radioactive pollution. In this presentation, we overview these activities for the atmospheric radionuclides in Japan as followings: 1. Investigations to evaluate radionuclide emissions by explosions at FNDPP in March 2011 and to estimate the respiration dose of the radiation at this stage. 2. Investigations to evaluate atmospheric transport and deposition processes of atmospheric radionuclide to determine the extent of radionuclide pollution. -- Based on results of the regular and urgent monitoring results, as well as the mapping of the distribution of radionuclide s accumulated by the deposition to the ground, restoration of their time-dependent emission rates has been tried, and processes determining atmospheric concentration and deposition to the ground have been investigated by using the model calculations. 3. Monitoring of the atmospheric concentrations of radionuclide after the initial, surge phase of FNDPP accident. 4. Investigations to evaluate re-suspension of radionuclide from the ground, including the soil and the vegetation. -- Intensive monitoring of the atmospheric concentrations and deposition amount of radionuclide after the initial, surge phase of the accident enable us to evaluate emission history from FNDPP, atmospheric transport and deposition processes, chemical and physical characteristics of atmospheric radionuclide especially of radio cesium, and re-suspension processes which has become dominant process to supply radio cesium to the atmosphere recently.

    Radiocesium ((134)Cs and (137)Cs) distribution in tree stems of Japanese cedar (aged 40-56 y), red pine (42 y), and oak (42 y) grown in Fukushima Prefecture were investigated approximately half a year after the Fukushima Dai-ichi nuclear accident. Japanese cedar, red pine, and oak were selected from five sites, one site, and one site, respectively. Three trees at each site were felled, and bark, sapwood (the outer layer of wood in the stem), and heartwood (the inner layer of wood in the stem) separately collected to study radiocesium concentrations measured by gamma-ray spectrometry. The radiocesium deposition densities at the five sites were within the range of 16-1020 kBq m(-2). The radiocesium was distributed in bark, sapwood, and heartwood in three tree species, indicating that very rapid translocation of radiocesium into the wood. The concentration of radiocesium in oak (deciduous angiosperm) bark was higher than that in the bark of Japanese cedar and red pine (evergreen gymnosperms). Both sapwood and heartwood contained radiocesium, and the values were much lower than that in the bark samples. The results suggest that radiocesium contamination half a year after the accident was mainly attributable to the direct radioactive deposition. The radiocesium concentrations in the Japanese cedar samples taken from five sites rose with the density of radiocesium accumulation on the ground surface. To predict the future dynamics of radiocesium in tree stems, the present results taken half a year after the accident are important, and continuous study of radiocesium in tree stems is necessary.

    We investigated the transfer of canopy-intercepted radiocesium to the forest floor during 3 years (July 2011~) following the Fukushima Dai-ichi Nuclear Power Plant accident. The cesium-137 (Cs-137) contents of throughfall, stemflow, and litterfall were monitored in two coniferous stands (plantation of Japanese cedar) and a deciduous broad-leaved forest stand (Japanese oak with red pine). We also measured an ambient dose rate at different height in the forest by using a survey meter (TCS-172B, Hitachi-Aloka Medical, LTD.) and a portable Ge gamma-ray detector (Detective-DX-100T, Ortec, Ametek, Inc.). Furthermore, effects of forest decontamination on the reduction of ambient dose rate were assessed quantitatively. Total Cs-137 deposition flux from the canopy to forest floor for the mature cedar, young cedar, and the mixed broad-leaved stands were 157 kBq/m^2, 167 kBq/m^2, and 54 kBq/m^2, respectively. These values correspond to 36%, 39% and 12% of total atmospheric input after the accident. The ambient dose rate showed an exponential decrease with time for all the forest sites, however the decreasing trend differed depending on the forest type. These data suggested that an ambient dose rate in forest environment can be variable in spatially and temporally reflecting the transfer of radiocesium from canopy to forest floor. We presented the analysis results of the relationship between radiocesium deposition flux and ambient dose rate at the forest floor. In addition to that, we reported the effects of forest decontamination (e.g., tree felling, removal of organic materials, woodchip pavement) on the reduction of ambient dose rate in the forest environment.

    We measured the concentrations of radiocesium ((134)Cs and (137)Cs) in a large web spider, Nephila clavata L. Koch (Nephilidae: Arachnida), collected at three sites at different distances from the Fukushima Dai-ichi Nuclear Power Plant about 1.5 y after the accident in March 2011. The radiocesium concentrations in spiders were highest in a streamside secondary forest 33 km northwest of the power plant: mean ± a standard deviation of 2.401 ± 1.197 Bq g(-1) dry for (134)Cs and 3.955 ± 1.756 Bq g(-1) dry for (137)Cs. In a hillside secondary forest 37 km northwest of the power plant, the mean concentrations of (134)Cs and (137)Cs were 0.825 ± 0.247 Bq g(-1) dry and 1.470 ± 0.454 Bq g(-1) dry, respectively. In a pine forest 62 km west of the power plant, very low radiocesium concentrations were detected, but in only a few individuals. The concentrations of (134)Cs and (137)Cs in spiders collected at each site tended to be correlated with the air radiation dose rate at each site. Since spiders are key components of food webs in forests, the high concentrations in this species at contaminated sites suggested that the radiocesium from the accident has transferred through food chains and reached to higher trophic level of the food chains.

    Radiocesium ( 137 Cs) migration from headwater forested areas to downstream rivers has been investigated in many studies since the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, which was triggered by a catastrophic earthquake and tsunami on 11 March 2011. The accident resulted in the release of a huge amount of radioactivity and its subsequent deposition in the environment. A large part of the radiocesium released has been shown to remain in the forest. The dissolved 137 Cs concentration and its temporal dynamics in river water, stream water, and groundwater have been reported, but reports of dissolved 137 Cs concentration in soil water remain sparse. In this study, soil water was sampled, and the dissolved 137 Cs concentrations were measured at five locations with different land-use types (mature/young cedar forest, broadleaf forest, meadow land, and pasture land) in Yamakiya District, located 35 km northwest of FDNPP from July 2011 to October 2012. Soil water samples were collected by suction lysimeters installed at three different depths at each site. Dissolved 137 Cs concentrations were analyzed using a germanium gamma ray detector. The dissolved 137 Cs concentrations in soil water were high, with a maximum value of 2.5 Bq/L in July 2011, and declined to less than 0.32 Bq/L by 2012. The declining trend of dissolved 137 Cs concentrations in soil water was fitted to a two-component exponential model. The rate of decline in dissolved 137 Cs concentrations in soil water (k 1 ) showed a good correlation with the radiocesium interception potential (RIP) of topsoil (0-5 cm) at the same site. Accounting for the difference of 137 Cs deposition density, we found that normalized dissolved 137 Cs concentrations of soil water in forest (mature/young cedar forest and broadleaf forest) were higher than those in grassland (meadow land and pasture land).

    A series of car-borne surveys using the Kyoto University RAdiation MApping (KURAMA) and KURAMA-II survey systems has been conducted over a wide area in eastern Japan since June 2011 to evaluate the distribution of air dose rates around the Fukushima Dai-ichi Nuclear Power Plant and to evaluate the time-dependent trend of decrease in air dose rates. An automated data processing system for the KURAMA-II system was established, which enabled rapid analysis of large amounts of data obtained using about 100 KURAMA-II units. The initial data used for evaluating the migration status of radioactive cesium were obtained in the first survey, followed by other car-borne surveys conducted over more extensive and wider measurement ranges. By comparing the measured air dose rates obtained in each survey (until December 2012), the decreasing trend of air dose rates measured through car-borne surveys was found to be more pronounced than those expected on the basis of the physical decay of radioactive cesium and of the air dose rates measured using NaI (Tl) survey meters in the areas surrounding the roadways. In addition, it was found that the extent of decrease in air dose rates depended on land use, wherein it decreased faster for land used as building sites than for forested areas. - Highlights: • Air dose rates distribution maps were constructed by Car-borne surveys. • KURAMA and KURAMA-II systems have been used for the measurement since 2011. • An automated data processing system for the KURAMA-II system was established. • Decreasing of the dose rates was more pronounced than those of the physical decay. • The dose rates decreased faster for building sites than for forested areas

    Large amounts of radioactive substances were released into the environment from the Fukushima Dai-ichi Nuclear Power Plants in eastern Japan as a consequence of the great earthquake (M 9.0) and tsunami of 11 March 2011. Radioactive substances discharged into the atmosphere first reached the Chiba Metropolitan Area on 15 March. We collected daily samples of air, fallout deposition, and tap water starting directly after the incident and measured their radioactivity. During the first two months maximum daily concentrations of airborne radionuclides observed at the Japan Chemical Analysis Center in the Chiba Metropolitan Area were as follows: 4.7 × 10(1) Bq m(-3) of (131)I, 7.5 Bq m(-3) of (137)Cs, and 6.1 Bq m(-3) of (134)Cs. The ratio of gaseous iodine to total iodine ranged from 5.2 × 10(-1) to 7.1 × 10(-1). Observed deposition rate maxima were as follows: 1.7 × 10(4) Bq m(-2) d(-1) of (131)I, 2.9 × 10(3) Bq m(-2) d(-1) of (137)Cs, and 2.9 × 10(3) Bq m(-2) d(-1) of (134)Cs. The deposition velocities (ratio of deposition rate to concentration) of cesium radionuclides and (131)I were detectably different. Radioactivity in tap water caused by the accident was detected several days after detection of radioactivity in fallout in the area. Radiation doses were estimated from external radiation and internal radiation by inhalation and ingestion of tap water for people living outdoor in the Chiba Metropolitan Area following the Fukushima accident.

    Surface seawater {sup 134}Cs and {sup 137}Cs samples were collected in the central and western North Pacific Ocean during the 2 yr after the Fukushima Dai-ichi Nuclear Power Plant accident to monitor dispersion patterns of these radioisotopes towards the Hawaiian Islands. In the absence of other recent sources and due to its short half-life, only those parts of the Pacific Ocean would have detectable {sup 134}Cs values that were impacted by Fukushima releases.

Here, most {sup 137}Cs activities (1.2-1.5 Bq m{sup -3}) were in the range of expected preexisting levels. Some samples north of the Hawaiian Islands (1.6-1.8 Bq m{sup -3}) were elevated above the 23-month baseline established in surface seawater in Hawaii indicating that those might carry atmospheric fallout. The 23-month time-series analysis of surface seawater from Hawaii did not reveal any seasonal variability or trends, with an average activity of 1.46 ± 0.06 Bq m{sup -3} (Station Aloha, 18 values). In contrast, samples collected between Japan and Hawaii contained {sup 134}Cs activities in the range of 1-4 Bq m{sup -3}, and {sup 137}Cs levels were about 2-3 times above the preexisting activities. We found that the southern boundary of the Kuroshio and Kuroshio extension currents represented a boundary for radiation dispersion with higher activities detected within and north of the major currents. The radiation plume has not been detected over the past 2 yr at the main Hawaiian Islands due to the transport patterns across the Kuroshio and Kuroshio extension currents.

    We measured the concentrations of radiocesium ( 134 Cs and 137 Cs) in a large web spider, Nephila clavata L. Koch (Nephilidae: Arachnida), collected at three sites at different distances from the Fukushima Dai-ichi Nuclear Power Plant about 1.5 y after the accident in March 2011. The radiocesium concentrations in spiders were highest in a streamside secondary forest 33 km northwest of the power plant: mean ± a standard deviation of 2.401 ± 1.197 Bq g −1 dry for 134 Cs and 3.955 ± 1.756 Bq g −1 dry for 137 Cs. In a hillside secondary forest 37 km northwest of the power plant, the mean concentrations of 134 Cs and 137 Cs were 0.825 ± 0.247 Bq g −1 dry and 1.470 ± 0.454 Bq g −1 dry, respectively.

    We consider fusion of heterogeneous data, consisting of multispectral imagery collected from the WorldView-2 satellite and aerial gamma-ray spectra collected during the NNSA Aerial Measuring System response to the Fukushima Dai-ichi Nuclear Power Plant crisis. These data are analyzed using the non-linear dimension reduction technique of diffusion maps. The data is then used for classification of regions in the scene. A strong spatial coherence is observed in the gamma-ray data that is closely coupled to the underlying terrain classification obtained from the multispectral data, indicating correlation between these a priori uncorrelated measurements.

    A strong radioactive contamination of the marine environment close to the damaged Fukushima Dai-ichi power plant has been observed since March 21. The high concentration of some nuclides ({sup 131}I, {sup 137}Cs, {sup 134}Cs, {sup 136}Cs, {sup 132}Te, {sup 132}I) comes from three possible sources: the liquid effluents from the damaged site, the atmospheric fallouts, and the weathering of contaminated soils. This information note presents and comments the most recent informations gathered by the French institute of radiation protection and nuclear safety (IRSN) since the previous information note from July 11 and devoted to the same topic. It presents the estimation of the relative contribution of each contamination source and the evolution with time of the marine contamination. The mapping of {sup 137}Cs concentrations in surface seawater allows to estimate the amount of total {sup 137}Cs in the marine environment and its evolution with time. {sup 137}Cs and {sup 134}Cs concentrations were measured both in samples of surface coastal sediments and in river fishes and seafood products (mainly fishes and molluscs). Results are reported in graphs showing their evolution with time. (J.S.)

    The French institute of radiation protection and nuclear safety (IRSN) collects and analyses regularly the published data concerning the contamination of the Japanese terrestrial environment caused by the Fukushima Dai-ichi power plant accident. This synthesis presents a status of the data recently obtained since the previous similar notes of April 12, May 25 and July 13. The note presents the detailed activity analysis of several surface soil samples, a mapping of {sup 137}Cs, {sup 134}Cs and {sup 131}I activities with the spatial distribution of samplings in the 20, 30, 80 and 100 km areas around the damaged power plant, the contamination of agriculture food products and a focus on some vegetable products showing a significant contamination, like tea leaves, 'yuzu' fruits, figs and rice. Some other products, like meat, fungi and some milk products show cesium contamination levels above the Japanese standards while cesium and iodine are no longer detected in drinking water. (J.S.)

    After the nuclear accident at TEPCO's Fukushima Dai-ichi power station in March, hydrogen explosions and reactor building explosion resulted in releases of radionuclides in the environment. Severe radioactive cesium and iodine contaminations have been observed in fallout deposition samples and soils in the East Japan. Radioactive cesium, iodine, uranium, and transuranic radionuclides were set as the monitoring targets in food safety tests. However, so far, only radioactive cesium and iodine were daily measured and reported by the Ministry of Health, Labour, and Welfare. The tedious and time consuming conventional alpha spectrometric method hampered the emergency monitoring U contamination in foods. In this work, we propose a simple and rapid analytical method for 238 U and 235 U/ 238 U isotope ratio analysis in fresh vegetables. This method was applied to the emergency monitoring of radioactive contamination after the nuclear accident at TEPCO's Fukushima Dai-ichi power station. The results showed no U contamination in fresh vegetables collected in Chiba and Ibaraki prefectures in April and May, 2011. (author)

    To estimate the radiocesium decreasing rates from persimmon trees during a period of about 3 y following the accident at Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP), we conducted measurements of tree tissue parts collected in 2011–2013. The sampling was carried out in Chiba, 220 km south of FDNPP; radioactive fallouts discharged from FDNPP had mainly been observed in March–April 2011 on the sampling site. We measured 137 Cs concentrations in the tree tissue parts, i.e., fruits (flesh, skin and seeds), leaves and newly emerged branches, and then the effective half-lives (T eff ) of 137 Cs were calculated. Leaf samples were classified into two types by sampling months according to the growing stages, that is, immature (April–May) and mature (June–November) leaves. All these parts showed exponential declines in 137 Cs concentration with good adjusted contribution ratios of higher than ca. 0.7. The calculated T eff values from all tissue parts were similar with the average of 229 d (range: 216–243 d). From these results, we concluded that each tree tissue was representative for the calculation of T eff . For comparison to these observation results, open source food monitoring data from 2011 to 2013 including 137 Cs data for persimmon fruits collected in Fukushima Prefecture were used to calculate T eff for persimmon trees. Values of T eff were obtained for persimmon fruits grown in each local government area in Fukushima Prefecture and they ranged from 303 to 475 d. - Highlights: • 137 Cs decreased exponentially from persimmon trees in Chiba after the Fukushima accident. • The effective half-lives (T eff ) of 137 Cs from fruit, leaf and new branch tissues were similar. • The Food monitoring data were used to calculate effective half-lives for persimmon trees in Fukushima. • The average of T eff in Chiba was ca. 230 d while that in Fukushima was ca. 400 d

    Shortly after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) was severely damaged in March 2011 by a large earthquake and subsequent tsunami, large amounts of radionuclides including 131 I, 134 Cs, 137 Cs and 90 Sr were released into the atmosphere and the marine environ- ment. These artificial radionuclides widely dispersed causing radioactive contaminations in several areas and concerns on the marine biota. In this study, a total of 52 seawater samples (10 stations) and 66 marine animals (9 stations) were collected from the Gulf of Thailand and the Andaman Sea between March 2012 and July 2013 for 137 Cs analysis. An ammonium molybdophosphate (AMP) method was used in conjunction with gammaspectrometry to measure 137 Cs in the seawater. 137 Cs was moreover extracted from the marine biota using a radiochemical technique followed by a measurement using low background proportional counters. The results showed 137 Cs concentrations in seawater ranging from 0.59 to 3.75 mBq/L (1.65±0.74 mBq/L). 137 Cs concentrations in benthic fish including Nemipterus hexodon and Saurida elongate were 0.06-1.23 Bq/kgww (0.24±0.26 Bq/kgww) and 0.07-0.64 Bq/kgww (0.16±0.12 Bq/kgww), respectively. Whereas, 137 Cs levels in squid (Loligo duvauceli) ranged between 0.03 and 0.15 Bq/kgww (0.08±0.04 Bq/kgww). An increase of 137 Cs concentrations in seawater and marine biota was not found when compared to those collected from the Gulf of Thailand and measured during 1989-1991. ERICA model was used to estimate radiation doses in the studied animals. Our results revealed that radiation doses of 137 Cs in N. hexodon and S. elongate were 0.7-4.2 nGy/hr (1.6±0.6 nGy/hr) and 0.7-3.4 nGy/hr (1.7±0.9 nGy/hr), respectively. While, a range of 0.7-3.2 nGy/hr (1.5±0.6 nGy/hr) was found in L. duvauceli. These radiation doses are well below the dose limit for aquatic organisms (10±Gy/hr). It can be concluded that Thai marine environment and animals have not been contaminated and not under a

    To explore the behavior of radionuclides released after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident in March 2011, and the distribution of radiocesium in paddy fields, we monitored radiocesium (Cs) and suspended sediment (SS) discharge from paddy fields. We proposed a rating scale for measuring the effectiveness of surface soil removal. Our experimental plots in paddy fields were located ∼40 km from the FDNPP. Two plots were established: one in a paddy field where surface soil was not removed (the "normally cultivated paddy field") and the second in a paddy field where the top 5-10 cm of soil was removed before cultivation (the "surface-removed paddy field"). The amounts of Cs and SS discharge from the paddy fields were continuously measured from June to August 2011. The Cs soil inventory measured 3 months after the FDNPP accident was approximately 200 kBq m(-2). However, after removing the surface soil, the concentration of Cs-137 decreased to 5 kBq m(-2). SS discharged from the normally cultivated and surface-removed paddy fields after puddling (mixing of soil and water before planting rice) was 11.0 kg and 3.1 kg, respectively, and Cs-137 discharge was 630,000 Bq (1240 Bq m(-2)) and 24,800 Bq (47.8 Bq m(-2)), respectively. The total amount of SS discharge after irrigation (natural rainfall-runoff) was 5.5 kg for the normally cultivated field and 70 kg for the surface-removed field, and the total amounts of Cs-137 discharge were 51,900 Bq (102 Bq m(-2)) and 165,000 Bq (317 Bq m(-2)), respectively. During the irrigation period, discharge from the surface-removed plot showed a twofold greater inflow than that from the normally cultivated plot. Thus, Cs inflow may originate from the upper canal. The topsoil removal process eliminated at least approximately 95% of the Cs-137, but upstream water contaminated with Cs-137 flowed into the paddy field. Therefore, to accurately determine the Cs discharge, it is important to examine Cs inflow from the

    The transfer coefficient (TF) from soil to rice plants of 134 Cs and 137 Cs in the form of radioactive deposition from the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident in March 2011 was investigated in three rice paddy fields in Minami-Soma City. Rice crops were planted in the following May and harvested at the end of September. Soil cores of 30-cm depth were sampled from rice-planted paddy fields to measure 134 Cs and 137 Cs radioactivity at 5-cm intervals. 134 Cs and 137 Cs radioactivity was also measured in rice ears (rice with chaff), straws and roots. The rice ears were subdivided into chaff, brown rice, polished rice and rice bran, and the 134 Cs and 137 Cs radioactivity concentration of each plant part was measured to calculate the respective TF from the soil. The TF of roots was highest at 0.48 ± 0.10 in the field where the 40 K concentration in the soil core was relatively low, in comparison with TF values of 0.31 and 0.38 in other fields. Similar trends could be found for the TF of whole rice plants, excluding roots. The TF of rice ears was relatively low at 0.019–0.026. The TF of chaff, rice bran, brown rice and polished rice was estimated to be 0.049, 0.10–0.16, 0.013–0.017 and 0.005–0.013, respectively. - Highlights: ► We investigated the transfer coefficient of 134 Cs and 137 Cs from soil to rice plants in Minami-Soma City due to the Fukushima accident in 2011. ► The rice ears, straws, roots, chaff, brown rice, polished rice, rice bran and soil samples have been measured by Ge-detector. ► Transfer coefficient of chaff, rice bran, brown rice, and polished rice is estimated as 0.049, ranging from 0.10 to 0.16, 0.013 to 0.017, and 0.005 to 0.013, respectively.

    Full Text Available A series of accidents at the Fukushima Dai-ichi Nuclear Power Plant following the Great East Japan Earthquake and tsunami of 11 March 2011 resulted in the release of radioactive materials to the ocean by two major pathways: direct release from the accident site and atmospheric deposition. A 1 yr, regional-scale simulation of 137Cs activity in the ocean offshore of Fukushima was carried out, the sources of radioactivity being direct release, atmospheric deposition, and the inflow of 137Cs deposited into the ocean by atmospheric deposition outside the domain of the model. Direct releases of 137Cs were estimated for 1 yr after the accident by comparing simulated results and measured activities adjacent to the accident site. The contributions of each source were estimated by analysis of 131I/137Cs and 134Cs/137Cs activity ratios and comparisons between simulated results and measured activities of 137Cs. The estimated total amounts of directly released 131I, 137Cs, and 137Cs were 11.1 ± 2.2 PBq, 3.5 ± 0.7 PBq, and 3.6 ± 0.7 PBq, respectively. Simulated 137Cs activities attributable to direct release were in good agreement with measured 137Cs activities not only adjacent to the accident site, but also in a wide area in the model domain, therefore this implies that the estimated direct release rate was reasonable. Employment of improved nudging data by JCOPE2 improved both the offshore transport result and the reproducibility of 137Cs activities 30 km offshore. On the other hand, simulated 137Cs activities attributable to atmospheric deposition were low compared to measured activities. The rate of atmospheric deposition into the ocean was underestimated because of a lack of measurements of deposition into the ocean when atmospheric deposition rates were being estimated. Simulated 137Cs activities attributable to the inflow of 137Cs deposited into the ocean outside the domain of the model were in good agreement with measured activities in the open

    To investigate the clinical efficacy of Fu Fan Huang Dai Pian(RIF) and arsenic trioxide (ATO) regimens for treatment of children with acute promyelocytic leukemia (APL) and to explore the risk factors affecting the prognosis of patients. The clinical data of 45 newly diagnosed APL children admitted in our hospital from January 2004 to May 2017 were analyzed retrospectively. Among 45 APL children, 25 children were treated by chemotherapetic regimen including RIF (RIF group), another 20 children were treated by chemotherapeutic regimen including ATO (ATO group). The follow-up was performed in all APL children. The prognosis and incidence of side reactions from drugs in 2 groups were compared, and the high risk factors affecting the prognosis of patients were analyzed. The median follow-up time was 49.8% months. In RIF group, no early death occured in 25 APL children; 5 cases did not achieve complete remission (CR) after induction therapy, CR rate was 88%. Out of 25 cases 2 caes relapsed, 3 cases died, 20 cases maintained contined CR (CCR), 2 cases failed to be followed-up. In ATO group, 2 cases suffered from early death, 5 cases did not achieve CR after induction therapy, CR rate was 90%, 2 caese relapsed and died, 15 cases maintained CCR, the follow-up failed in 1 caes. The 5 year- OS and EFS rate in all the patients were predicted as (82.2±6.2)% and (76.4±6.6)% respectively. The OS and EFS rate in RIF group were (86.1±7.4)% and (78.4±8.6)% respectively, which were significantly different from OS and EFS rate (76.4%±10.6%) and (74.0%±10.1%) respectively in ATO group (all P>0.05). As for the side reaction from drug, except for the cardiac damage (P0.05). In addition, the 5 year-OS and EFS rates in APL children with CNSL were significantly lower than those in APL children without CNSL (all Phigh risk were significantly lower than those in APL children reached M1 after induction therapy and with low and standerd risk (Ptreatment of APL children.

    The Oginosawa River catchment lies 15 km south-west of the Fukushima Dai-ichi nuclear plant and covers 7.7 km 2 . Parts of the catchment were decontaminated between fall 2012 and March 2014 in preparation for the return of the evacuated population. The General-purpose Terrestrial Fluid-flow Simulator (GETFLOWS) code was used to study sediment and 137 Cs redistribution within the catchment, including the effect of decontamination on redistribution. Fine resolution grid cells were used to model local features of the catchment, such as paddy fields adjacent to the Oginosawa River. The simulation was verified using monitoring data for river water discharge rates (r = 0.92), suspended sediment concentrations, and particulate 137 Cs concentrations (r = 0.40). Cesium-137 input to watercourses came predominantly from land adjacent to river channels and forest gullies, e.g. the paddy fields in the Ogi and Kainosaka districts, as the ground in these areas saturates during heavy rain and is easily eroded. A discrepancy between the simulation and monitoring results on the sediment discharge rate following decontamination may be explained by fast erosion occurring after decontamination. Forested areas far from the channels only made a minor contribution to 137 Cs input to watercourses, total erosion of between 0.001 and 0.1 mm from May 2011 to December 2015, as ground saturation is infrequent in these areas. The 2.3-6.9% y -1 decrease in the amount of 137 Cs in forest topsoil over the study period can be explained by radioactive decay (approximately 2.3% y -1 ), along with a migration downwards into subsoil and a small amount of export. The amount of 137 Cs available for release from land adjacent to rivers is expected to be lower in future than compared to this study period, as the simulations indicate a high depletion of inventory from these areas by the end of 2015. However continued monitoring of 137 Cs concentrations in river water over future years is advised, as

    The dose rates of radiation absorbed by wild rodents inhabiting a site severely contaminated by the Fukushima Dai-ichi Nuclear Power Plant accident were estimated. The large Japanese field mouse (Apodemus speciosus), also called the wood mouse, was the major rodent species captured in the sampling area, although other species of rodents, such as small field mice (Apodemus argenteus) and Japanese grass voles (Microtus montebelli), were also collected. The external exposure of rodents calculated from the activity concentrations of radiocesium ((134)Cs and (137)Cs) in litter and soil samples using the ERICA (Environmental Risk from Ionizing Contaminants: Assessment and Management) tool under the assumption that radionuclides existed as the infinite plane isotropic source was almost the same as those measured directly with glass dosimeters embedded in rodent abdomens. Our findings suggest that the ERICA tool is useful for estimating external dose rates to small animals inhabiting forest floors; however, the estimated dose rates showed large standard deviations. This could be an indication of the inhomogeneous distribution of radionuclides in the sampled litter and soil. There was a 50-fold difference between minimum and maximum whole-body activity concentrations measured in rodents at the time of capture. The radionuclides retained in rodents after capture decreased exponentially over time. Regression equations indicated that the biological half-life of radiocesium after capture was 3.31 d. At the time of capture, the lowest activity concentration was measured in the lung and was approximately half of the highest concentration measured in the mixture of muscle and bone. The average internal absorbed dose rate was markedly smaller than the average external dose rate (sampling area was estimated to be approximately 52 μGy h(-1) (1.2 mGy d(-1)), even 3 years after the accident. This dose rate exceeds 0.1-1 mGy d(-1) derived consideration reference level for Reference rat

    We monitored the vertical distribution of 137 Cs in soil profiles under eight different land uses for the 2 y after the Fukushima Dai-ichi Nuclear Power Plant accident, and discussed the temporal changes in the early-stage of the migration and the determinants of the initial distribution. The soil samples were collected for four surveys using a scraper plate at each study site, which consisted of three forests (mixed forest, mature cedar, and young cedar), two grasslands (pasture and meadow) and three abandoned agricultural fields (farm land, tobacco field, and paddy field). The land use patterns have a large influence on some soil properties and the migration processes of 137 Cs above ground, resulting in different distribution of 137 Cs in those soil profiles. Specifically, the secondary deposition of 137 Cs from the coniferous canopy, retention of 137 Cs by litter layer, and the homogenization of 137 Cs concentrations in surface soil by natural soil mixing such as the disturbance by cattle grazing, roots growing and the formation of needle ice were important to cause redistribution of the deposited 137 Cs. Only in the paddy field, the 137 Cs inventory in subsurface soils (5–10 cm) gradually increased and comprised 26% of the total 137 Cs in 2 y, showing the downward migration of 137 Cs to subsurface soil. In the other sites, it was considered that 137 Cs were strongly adsorbed by soil particles and rarely migrated downward as soluble form. Vertical distributions during the first survey were able to be used as the initial distributions and were well fitted to the exponential equation. The distribution parameters α (relaxation depth) and β (relaxation mass depth), calculated by the exponential equation were correlated with RIP (r = −0.806, p < 0.05), macro pore (r = 0.651, p = 0.11), and dispersible fine particle content (r = 0.856, p < 0.05). It indicated that the initial distribution would be influenced by the Cs fixation ability of soil, and the

    On 11 March 2011, an earthquake occurred about 130 km off the Pacific coast of Japan's main island Honshu, followed by a large tsunami. The resulting loss of electric power at the Fukushima Dai-ichi nuclear power plant developed into a disaster causing massive release of radioactivity into the atmosphere. In this study, we determine the emissions into the atmosphere of two isotopes, the noble gas xenon-133 ("1"3"3Xe) and the aerosol-bound caesium-137 ("1"3"7Cs), which have very different release characteristics as well as behavior in the atmosphere. To determine radionuclide emissions as a function of height and time until 20 April, we made a first guess of release rates based on fuel inventories and documented accident events at the site. This first guess was subsequently improved by inverse modeling, which combined it with the results of an atmospheric transport model, FLEXPART, and measurement data from several dozen stations in Japan, North America and other regions. We used both atmospheric activity concentration measurements as well as, for "1"3"7Cs, measurements of bulk deposition. Regarding "1"3"3Xe, we find a total release of 15.3 (uncertainty range 12.2-18.3) EBq, which is more than twice as high as the total release from Chernobyl and likely the largest radioactive noble gas release in history. The entire noble gas inventory of reactor units 1-3 was set free into the atmosphere between 11 and 15 March 2011. In fact, our release estimate is higher than the entire estimated "1"3"3Xe inventory of the Fukushima Dai-ichi nuclear power plant, which we explain with the decay of iodine-133 (half-life of 20.8 h) into "1"3"3Xe. There is strong evidence that the "1"3"3Xe release started before the first active venting was made, possibly indicating structural damage to reactor components and/or leaks due to overpressure which would have allowed early release of noble gases. For "1"3"7Cs, the inversion results give a total emission of 36.6 (20.1-53.1) PBq, or about

We used both atmospheric activity concentration measurements as well as, for 137Cs, measurements of bulk deposition. Regarding 133Xe, we find a total release of 15.3 (uncertainty range 12.2–18.3 EBq, which is more than twice as high as the total release from Chernobyl and likely the largest radioactive noble gas release in history. The entire noble gas inventory of reactor units 1–3 was set free into the atmosphere between 11 and 15 March 2011. In fact, our release estimate is higher than the entire estimated 133Xe inventory of the Fukushima Dai-ichi nuclear power plant, which we explain with the decay of iodine-133 (half-life of 20.8 h into 133Xe. There is strong evidence that the 133Xe release started before the first active venting was made, possibly indicating structural damage to reactor components and/or leaks due to overpressure which would have allowed early release of noble gases.

    On 11 March 2011, an earthquake occurred about 130 km off the Pacific coast of Japan's main island Honshu, followed by a large tsunami. The resulting loss of electric power at the Fukushima Dai-ichi nuclear power plant developed into a disaster causing massive release of radioactivity into the atmosphere. In this study, we determine the emissions into the atmosphere of two isotopes, the noble gas xenon-133 ({sup 133}Xe) and the aerosol-bound caesium-137 ({sup 137}Cs), which have very different release characteristics as well as behavior in the atmosphere.

  7. Will the real Robert Neville please, come out? Vampirism, the ethics of queer monstrosity, and capitalism in Richard Matheson's I am legend?

    In this article, I argue that Richard Matheson's (1954) vampire novella, I Am Legend, encodes the protagonist's, Robert Neville, traumatic recognition of his queer sexuality in its monstrosity (the unspeakability of male penetrability). Neville's identification with and desire for his undead neighbor, Ben Cortman, are symbolically codified through three different registers: intertextual references to vampiric conventions and codes, the semiotics of queer subculture, and a structure of doubling that links Neville to the queer vampire. Although Neville avoids encountering his unspeakable queer desire, which could be represented only at the level of the Lacanian Real, he must still confront Cortman's obsessive exhortations for him to come out. Only when he symbolically codifies his abnormality in its own monstrosity, by viewing himself through mutant vampires' eyes, can Neville reconfigure the ethical relationship between self and other, humans and mutant humans-vampires. However progressive Matheson's novella is in its advocacy of minority sexual rights, it still renders capitalism's problematic relationship with queer subjectivity invisible. Although capitalism overdetermines every aspect of the social field and makes Neville's daily life possible in its surplus enjoyment, the fundamental antagonism (class struggle) in capitalism is obscured by the assertion of identity politics.

  8. Kalman filters for assimilating near-surface observations in the Richards equation - Part 2: A dual filter approach for simultaneous retrieval of states and parameters

    We present a dual Kalman Filter (KF) approach for retrieving states and parameters controlling soil water dynamics in a homogenous soil column by using near-surface state observations. The dual Kalman filter couples a standard KF algorithm for retrieving the states and an unscented KF algorithm for retrieving the parameters. We examine the performance of the dual Kalman Filter applied to two alternative state-space formulations of the Richards equation, respectively differentiated by the type of variable employed for representing the states: either the soil water content (θ) or the soil matric pressure head (h). We use a synthetic time-series series of true states and noise corrupted observations and a synthetic time-series of meteorological forcing. The performance analyses account for the effect of the input parameters, the observation depth and the assimilation frequency as well as the relationship between the retrieved states and the assimilated variables. We show that the identifiability of the parameters is strongly conditioned by several factors, such as the initial guess of the unknown parameters, the wet or dry range of the retrieved states, the boundary conditions, as well as the form (h-based or θ-based) of the state-space formulation. State identifiability is instead efficient even with a relatively coarse time-resolution of the assimilated observation. The accuracy of the retrieved states exhibits limited sensitivity to the observation depth and the assimilation frequency.

    Full Text Available Epiphytic orchids have received considerable study, yet little has been published on their germination requirements in situ involving mycorrhizal fungi. Such research has been hampered by the small, dust-like size of seeds and leafless seedlings (protocorms which are difficult to pinpoint on natural substrates, especially those on arboreal substrates (tree limbs. We report a novel seed sowing and retrieval method, modified from one applied to terrestrial orchids, used in the acquisition of epiphytic orchid protocorms from the Florida Panther National Wildlife Refuge. Seeds from two epiphytic orchid species (Epidendrum amphistomum A. Richard, E. nocturnum Jacquin were placed in separate nylon mesh packets secured within 35 mm plastic slide mounts, and affixed to tree bark using gutter mesh and a staple gun. To confirm that the embryos were viable, some seeds were also sown on asymbiotic media in the laboratory which subsequently germinated after 52 days incubation. Of 60 packets distributed among 18 tree limb sites, one packet – harboring seeds of E. amphistomum affixed to pop ash (Fraxinus caroliniana Mill. on a moss substrate – harbored protocorms after 267 days. Using molecular markers, a fungus assignable to the Ceratobasidiaceae, appears to be the mycorrhizal associate of these protocorms suggesting that this fungus may be associated with the germination process in situ.

    The conference was related with some of the major questions concerning global energy governance today, the role of the different international organizations dealing with energy, the rules of the game between market and state players, the efforts to deal with climate change, and the integration of emerging countries in global energy governance, the roles of the different international organizations dealing with energy (will we see further fragmentation or more cooperation between them?). Tatsuo Masuda in his contribution discussed global energy governance from an oil perspective. Andre Mernier noted the particular nature of the Energy Charter, which, as it is founded upon an international treaty, is unlike other organizations in being legally binding. The legal basis of the organization means that agreements are especially powerful. Then Richard H. Jones underlined that last summer's volatility in oil markets, the ensuing financial and economic crisis, the major disruption in gas supplies to European markets this winter and the upcoming climate change negotiations have led to increasing calls for a stronger global dialogue on energy issues. This dialogue should deal with prices and investment, energy security and climate change

    Full Text Available Il contributo proposto ha l’obiettivo di analizzare alcuni significativi brani del tessuto urbano della periferia est di Roma, adottando metodi interpretativi legati alla storia, alla società, alla programmazione urbanistica e alla costruzione. Gli aspetti salienti del quadrante orientale della periferia romana verranno così delineati partendo “dal di dentro”, sottolineandone i percorsi, gli spazi e i nuclei compositivi che sono all’origine della struttura e della forma stessa dei quartieri disposti a cavallo del Grande Raccordo Anulare. In questo ambito, si pone l’attenzione su alcuni episodi chiave che vedono protagoniste le nuove chiese che riescono a creare una centralità all’interno dei quartieri periferici sostituendo le biblioteche, le piazze e i centri commerciali.  Analizzando da vicino questi esempi, si scopre come di recente sono state realizzate chiese firmate da architetti di fama internazionale proprio allo scopo di rafforzare, o meglio di costruire, un fattore identitario per ciascun quartiere ubicato nel settore orientale della città. Partendo quindi dal generale si arriva a indagare una chiesa e un quartiere che possono essere considerati un modello da seguire per tutta la periferia a ridosso del GRA: la chiesa giubilare di Dio Padre Misericordioso progettata da Richard Meier nel quartiere di Tor Tre Teste. La sequenzialità degli eventi che hanno contraddistinto il concorso per la progettazione della chiesa, la scelta della proposta di Richard Meier, la complessità del cantiere, l’analisi tecnica, stilistica e simbolica della realizzazione finale sono quindi analizzate nell’ambito del rapporto con il quartiere e del tentativo di realizzare (attraverso di essa un centro di attrazione per tutta la periferia.   The article analyses some significant parts of the urban tissue at the eastern periphery of Rome, using the interpretative methods inherent to history, society, urban programming and construction

    Radioactive materials deposited on the land surface of Fukushima Prefecture from the Fukushima Dai-ichi Nuclear Power Plant explosion is a crucial issue for a number of reasons, including external and internal radiation exposure and impacts on agricultural environments and aquatic biota. Predicting the future distribution of radioactive materials and their fates is therefore indispensable for evaluation and comparison of the effectiveness of remediation options regarding human health and the environment. Cesium-137, the main radionuclide to be focused on, is well known to adsorb to clay-rich soils; therefore its primary transportation mechanism is in the form of soil erosion on the land surface and transport of sediment-sorbed contaminants in the water system. In this study, we applied the Soil and Cesium Transport model, which we have developed, to predict a long-term cesium distribution in the Fukushima area, based on the Universal Soil Loss Equation and simple sediment discharge formulas. The model consists of calculation schemes of soil erosion, transportation and deposition, as well as cesium transport and its future distribution. Since not all the actual data on parameters is available, a number of sensitivity analyses were conducted here to find the range of the output results due to the uncertainties of parameters. The preliminary calculation indicated that a large amount of total soil loss remained in slope, and the residual sediment was transported to rivers, deposited in rivers and lakes, or transported farther downstream to the river mouths. Most of the sediment deposited in rivers and lakes consists of sand. On the other hand, most of the silt and clay portions transported to river were transported downstream to the river mouths. The rate of sediment deposition in the Abukuma River basin was three times as high as those of the other 13 river basins. This may be due to the larger catchment area and more moderate channel slope of the Abukuma River basin

    Radiocesium migration from headwater forested catchment is important perception as output from the forest which is also input to the subsequent various land use and downstream rivers after Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. In this study, dissolved Cs-137 concentration of stream water, soil water and groundwater were measured. Observations were conducted at headwater catchment in Yamakiya district, located 35 km northwest of FDNPP from April 2014 to November 2015. Stream water discharge was monitored and stream water samples were taken at main channel and sub channel. Stream water discharge was monitored by combination of parshallflume and v-notch weir. Stream water was sampled manually at steady state condition in 3-4 month interval and also intense few hours interval sampling were conducted during rainfall events using automated water sampler. Around the sub channel, it is found that there is a regularly saturated area at the bottom of the slope, temporary saturated area which saturate during the rainy season in summer and regularly dry area. 6 interval cameras were installed to monitor the changing situation of saturated area. Suction lysimeters were installed at three areas (regularly saturated area, temporary saturated area and dry area) for sampling soil water in depth of 0.1 m and 0.3 m. Boreholes were installed at three points along the sub channel. Three boreholes with depth of 3 m, 5 m and 10 m were installed at temporary saturated area, 20 m upstream of sub channel weir. Another three boreholes with depth of 3 m, 5 m and 10 m were installed at dry area, 40 m upstream of sub channel weir. And a borehole with depth of 20 m was installed at ridge of sub catchment, 52 m upstream of sub channel weir. Groundwater was sampled by electrically powered pump and groundwater level was monitored. Also suction-free lysimeter was installed at temporary saturated area for sampling the near surface subsurface water. Soil water samples were collected

    Japan Atomic Energy Agency (JAEA) has carried out 'the project on the Long-term Assessment of Transport of Radioactive Contaminant in the Environment of Fukushima (F-TRACE project)' since the end of 2012. Radioactive caesium (Cs) has been distributed by the fallout by the Fukushima Dai-ichi Nuclear Power Plant (1F-NPP) accident, and forests in mountain areas have large amount of inventory of radioactive Cs and cover relatively large part of contaminated area of Fukushima. In this project, the transport behavior of radioactive Cs from the forests to biosphere and sea is evaluated by computer simulation based on the results of field observation and laboratory experiments. The results are used to predict evolution of effective dose of the residents in the affected area due to the transport, specify the dominant pathway of Cs, and propose effective methodology to constrain the transport along the pathway. This study reports the specific transport behavior of Cs observed in the basins of five rivers by means of the field investigation and laboratory experiments during the first year of the project. Radioactive Cs located at the crown was considered to be transported to the soil surface by litter fall, stem flow and canopy drip in the Japanese cedar tree forests. Even after two years since the accident, more than 90% of radioactive Cs was still been remained within 5 cm depth from the top of the soil, indicating that the distribution coefficient of radioactive Cs onto the specific minerals such as clay was significantly high. In the river, relatively higher dose rate was observed at the flood channel where fine-grained soil particles were trapped by growing vegetation, while low dose rate was observed beside the river channel where coarse sand or gravel accumulated. The results suggested that fine-grained soil particles containing minerals adsorbing large amount of radioactive Cs were transported in high water level and trapped by the vegetation. In the dam

    This presentation will show the results of a paper currently under review in ACPD and some additional new results, including more data and with an independent box modeling approach to support some of the findings of the ACPD paper. On 11 March 2011, an earthquake occurred about 130 km off the Pacific coast of Japan's main island Honshu, followed by a large tsunami. The resulting loss of electric power at the Fukushima Dai-ichi nuclear power plant (FD-NPP) developed into a disaster causing massive release of radioactivity into the atmosphere. In this study, we determine the emissions of two isotopes, the noble gas xenon-133 (133Xe) and the aerosol-bound caesium-137 (137Cs), which have very different release characteristics as well as behavior in the atmosphere. To determine radionuclide emissions as a function of height and time until 20 April, we made a first guess of release rates based on fuel inventories and documented accident events at the site. This first guess was subsequently improved by inverse modeling, which combined the first guess with the results of an atmospheric transport model, FLEXPART, and measurement data from several dozen stations in Japan, North America and other regions. We used both atmospheric activity concentration measurements as well as, for 137Cs, measurements of bulk deposition. Regarding 133Xe, we find a total release of 16.7 (uncertainty range 13.4-20.0) EBq, which is the largest radioactive noble gas release in history not associated with nuclear bomb testing. There is strong evidence that the first strong 133Xe release started early, before active venting was performed. The entire noble gas inventory of reactor units 1-3 was set free into the atmosphere between 11 and 15 March 2011. For 137Cs, the inversion results give a total emission of 35.8 (23.3-50.1) PBq, or about 42% of the estimated Chernobyl emission. Our results indicate that 137Cs emissions peaked on 14-15 March but were generally high from 12 until 19 March, when they

    Data assimilation is becoming increasingly popular in hydrological and earth system modeling, as it allows for direct integration of multisource observation data in modeling predictions and uncertainty reduction. For this reason, data assimilation has been recently the focus of much attention also for integrated surface-subsurface hydrological models, whereby multiple terrestrial compartments (e.g., snow cover, surface water, groundwater) are solved simultaneously, in an attempt to tackle environmental problems in a holistic approach. Recent examples include the joint assimilation of water table, soil moisture, and river discharge measurements in catchment models of coupled surface-subsurface flow using the ensemble Kalman filter (EnKF). Although the EnKF has been specifically developed to deal with nonlinear models, integrated hydrological models based on the Richards equation still represent a challenge, due to strong nonlinearities that may significantly affect the filter performance. Thus, more studies are needed to investigate the capabilities of EnKF to correct the system state and identify parameters in cases where the unsaturated zone dynamics are dominant. Here, the model CATHY (CATchment HYdrology) is applied to reproduce the hydrological dynamics observed in an experimental hillslope, equipped with tensiometers, water content reflectometer probes, and tipping bucket flow gages to monitor the hillslope response to a series of artificial rainfall events. We assimilate pressure head, soil moisture, and subsurface outflow with EnKF in a number of assimilation scenarios and discuss the challenges, issues, and tradeoffs arising from the assimilation of multisource data in a real-world test case, with particular focus on the capability of DA to update the subsurface parameters.

    Full Text Available Beyond the Soundtrack: Representing Music in Cinema (edited by Daniel Goldmark, Lawrence Kramer and Richard Leppert, Berkeley, University of California Press, 2007, viii-324 pp. offers sixteen essays of various authors about film music. These papers were presented in 2004 in a study congress at the University of Minnesota. In introducing the book, the editors assert an assumption, today broadly accepted: indeed they affirm, that music has traditionally been regarded as a subordinate element in cinematographic text: film music literature still has a marginal position in the much larger field of film studies which focuses on image, narrative, film history. In this theoretical and historiographic context, the expression “Beyond the Soundtrack” is meant to be more than a title: it is the manifesto of a conceptual shift. We can summarize this change in reconsidering the importance of film music, in order to understand a movie not only as a visual, but also as a musical medium. The change of paradigm brings renewed questions and completely new issues. If we abandon the assumption, at this point obsolete, that film music has a mere functional role, it will be necessary to ask not how to conceptualize the use of music in film, but rather how the film conceptualizes music: how films imagine music, how films represent music as an artistic and social phenomenon, and how films position music as an integral parts of a fictional world. Such questions aim to consider film music not as an atmospheric expedient, but «as an agent, a force, and an object engaged in ongoing negotiations with image, narrative, and context», as the editors assert at the very beginning of their book.

    Full Text Available Richard Wright's collection of short novella's, Uncle Tom's Children, was originally published in 1938; in 1940, after the success of Native Son, a new printing of the text appeared with two additions. The first was the introductory essay entitled "The Ethics of Living Jim Crow," which was written in 1937, and later served as part of Black Boy. The second was the novella "Bright and Morning Star." Michel Fabre notes that Harper's Magazine rejected this story, "but since it fit Party specifications even better than had the four previous stories, New Masses published it as part of a special literary supplement on May 10, [1938]" (164 . In fact, perhaps because New Masses originally published the final story, critical attention to the revised edition of book almost exclusively posits that the 1940 edition reflects Wright's commitment to Communism at the time. However, several of Wright's other writings-including the introductory essay to the 1940 edition, "The Ethics of Living Jim Crow;" "Blue print for Negro Writing," first published in New Challenge in the fall of 1937; "I Tried to be a Communist," first published in Atlantic Monthly in August and September 1944; and his responses to the Communist party's review of Native Son in 1940-also indicate that his focus in the late 1930s was more on the development of an individual black consciousness than on advancing the causes of the Communist party. By juxtaposing the final two stories, "Fire and Cloud" and "Bright and Morning Star," and considering them in terms of the other writings indicated above, I argue that the 1940 edition of Uncle Tom's Children (with the two additions demonstrates Wright's growing ambivalence with the Communist Party between the years of 1937 and 1940.

A Google search of «Charles Richard de Beauregard». Charles de Beauregard focused his professional work mainly on the treatment of the urethral sequela of blennorrhagia, phimosis and paraphimosis. He introduced to 18th century Spanish society (with purported originality and clear commercial interests) therapeutic methods based on lead acetate that had already been developed in France by Thomas Goulard. The urethral sequela of diseases such as blennorrhagic urethritis, stenotic phimosis and paraphimosis were highly prevalent in 18th century Madrid and required complex solutions for the practice of urology of that era. Charles de Beauregard introduced innovative but not original treatments that were invasive but not bloody and that provided him with fame and social prestige. He advertised his professional activity and marketed his therapeutic products through advertisements submitted to the daily press (Madrid Gazette, Gaceta de Madrid). Copyright © 2015 AEU.

    Maria Renata Dolce

    2015-07-01

    Full Text Available Abstract – This paper will analyze the ‘historical’ novel Gould’s Book of Fish (2001 by the Tasmanian writer Richard Flanagan with the aim of reflecting upon the power of the creative word as a means to forge reality, shape identities, mask or unmask truths, and also to prefigure a different, alternative world order based on commonly negotiated and thus shared values. The postmodernist revisiting of the traditional genre of the historical novel does not compromise the postcolonial commitment of the writer: Flanagan’s incursions into the Australian colonial past are informed by his concern for urgent social and political causes which has characterized his unswerving fight against all systems of inequality and exploitation. In his novel, the subversion of the linear causal relation of events which calls into question the truthfulness and objectivity of history, together with the foregrounded metanarrative reflection on the art of writing, contribute to the revisiting and re-discussing of the myth of progress and the cult of rationality at the very roots of Western civilization and of its imperialistic enterprise. Flanagan’s ‘anti-historical’ historical novel tackles urgent questions about modernity interrogating the founding narratives of the Australian national identity, in order to explore the uncontrollable and shifting areas of the contemporary ‘transnation’ in which the traditional categories shaping subjectivities are disrupted. As the paper will demonstrate, the writer digs into the past of his nation not simply in order to unravel its hidden histories but to detect the profound, inextricable interconnections with the present across different times and spaces. Feelings and experiences that exist above and beyond historical contingencies and cultural differences represent the writer’s privileged area of investigation as they trespass upon conventional and artificial boundaries revealing what it is that makes us all

    Full Text Available We used the mitochondria DNA COI (cytochrome c oxidase subunit I sequence as a genetic marker to analyze the population genetic structure of two species of freshwater copepods, Neodiaptomus schmackeri (Poppe and Richard, 1892 and Mongolodiaptomus birulai (Rylov, 1922 from Taiwan. Four populations with 51 individuals of N. schmackeri and five populations with 65 individuals of M. birulai were included. We compared the nucleotide sequences of a 635-bp fragment of the COI gene of N. schmackeri and a 655-bp fragment of the COI gene of M. birulai, and eight and 14 unique haplotypes were recorded, respectively. Tseng-Wen reservoir and Wu-San-Tao reservoir are linked by a channel, and the gene flow between them was unrestricted (Fst = 0.058; Nm = 4.04; Fst, population differentiation parameter; Nm, the number of succesfull migrants per generation; the gene flow between all other populations of both species was restricted (Fst = 0.4–0.99; Nm = 0–0.37. Based on the COI gene diversification pattern, we suggest that most populations of N. schmackeri and M. birulai are isolated from each other. According to the neighbor-joining tree and the minimum spanning network (MSN, the species have similar metapopulation genetic structures. Genetic distance was not found to be correlated with geographical distance. The genetic diversification pattern was not shown to be comparable with geographical isolation owing to long-distance separation. The genetic structure of the present populations may result from serial extinction and redistribution of the populations formed in each reservoir relative to time. Human activity in the reservoirs with regards to water resource management and the fishery industry also exerts an effect on population redistribution.

Samples from the National Atmospheric Deposition Program were analyzed for the period of March 8-April 5, 2011. Calculated 1- or 2-week radionuclide deposition fluxes at 35 sites from Alaska to Vermont ranged from 0.47 to 5,100 Becquerels per square meter during the sampling period of March 15-April 5, 2011. No fission-product isotopes were measured in National Atmospheric Deposition Program samples obtained during March 8-15, 2011, prior to the arrival of contaminated air in North America.

    After the accident of TEPCO's Fukushima Dai-ichi Nuclear Power Station occurred on March 11, 2011, actions for controlling the accident and protective actions for the residents like evacuation were taken. In parallel with this, it has been developed to reform the nuclear regulatory systems and the emergency preparedness and response systems in Japan. Especially the Nuclear Regulation Authority's Nuclear Emergency Preparedness and Response Guidelines were adopted with the introducing the basic concepts and the criteria on the basis of the IAEA's safety standards and differed greatly from the prior guidelines. Thus the arrangement of emergency response systems, resources and the operational procedures will be developed complying with according to the guidelines in municipalities around the nuclear power station sites. This work attempts to provide a plain explanation as possible for the regional officials and emergency workers about the basic concepts of the new guidelines. (author)

    Through wall degradation was found on the extraction steam drain piping of Unit 6 of Fukushima Dai-ichi Nuclear Power Plant owned by Tokyo Electric Power Company after replacement of the turbine rotors with those of higher thermal efficiency. The mechanism of this degradation was loss of material due to liquid drop impingement. Since the estimated life time of the piping based on wall thickness measurements before the replacement was at least 9 years, the rapid wall thinning occurred after the replacement. This paper describes a summary of the phenomenon, its degradation mechanism and root cause, a temporary measurement taken for an immediate action and permanent measures taken during the next refueling outage.

    The atmospheric release of 131 I and 137 Cs in the early phase of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident from March 12 to 14, 2011 was estimated by combining environmental data with atmospheric dispersion simulations under the assumption of a unit release rate (1 Bq h −1 ). For the simulation, WSPEEDI-II computer-based nuclear emergency response system was used. Major releases of 131 I (>10 15 Bq h −1 ) were estimated when air dose rates increased in FNPP1 during the afternoon on March 12 after the hydrogen explosion of Unit 1 and late at night on March 14. The high-concentration plumes discharged during these periods flowed to the northwest and south–southwest directions of FNPP1, respectively. These plumes caused a large amount of dry deposition on the ground surface along their routes. Overall, the spatial pattern of 137 Cs and the increases in the air dose rates observed at the monitoring posts around FNPP1 were reproduced by WSPEEDI-II using estimated release rates. The simulation indicated that air dose rates significantly increased in the south–southwest region of FNPP1 by dry deposition of the high-concentration plume discharged from the night of March 14 to the morning of March 15. - Highlights: ► Source term during the Fukushima Dai-ichi Nuclear Power Plant accident was estimated. ► Atmospheric dispersion simulation was carried out for estimation. ► Major releases were estimated in the afternoon on March 12 and the night on March 14. ► Air dose rate increased due to dry deposition during the night of March 14.

    Full Text Available El Índice de Estética Dental, DAI, permite determinar la severidad de las maloclusiones, con lo que se puede priorizar la necesidad de tratamiento ortodóncico de los pacientes. Material y Métodos: la muestra fue de 123 modelos de estudio pretratamiento de ortodoncia, se valoraron los modelos de estudio con el Índice de Estética Dental, se tabuló y calculó la estadística descriptiva con programa Microsoft Office Excel 2007. Resultados: El promedio del DAI fue de 39.84, el 53% de la población presentó una maloclusión muy severa con necesidad de tratamiento obligatorio, el 17.9% con maloclusión severa con necesidad de tratamiento deseable por el paciente, la categoría de maloclusión definitiva, que requiere tratamiento, se presentó en el 17.1% y solo el 11.4% presentó una oclusión normal sin necesidad de tratamiento. Conclusión: En la población de estudio fue mayor el porcentaje de maloclusión muy severa, las otras tres categorías del índice presentaron valores del 17% al 11%. Las mujeres que acudieron a atención con el ortodoncista presentaron mayor porcentaje de severidad de maloclusión que los hombres. Estos porcentajes demuestran que los pacientes que acuden, o son remitidos al ortodoncista, presentan maloclusiones severas.

    2017-09-01

    Full Text Available Este ensaio defende que o pensamento pós-analítico e pós-filosófico de Richard Rorty pode assumir uma função – de caráter profilático – muito interessante no âmbito dos estudos literários acadêmicos e na crítica literária em geral: suas reflexões críticas funcionam como uma advertência contra certas pretensões cientificistas da filosofia e, por consequência, das teorias literárias em geral. Os variados usos e objetivos da linguagemhumana em atos interpretativos – como na crítica literária – extrapolam a noção moderna de verdade como correspondência; o objetivo da crítica não é, pois, "a verdade", mas simplesmente continuar e enriquecer a grande e interminável conversação que é a cultura humana. A crítica só pode dizer “verdades” se entendermos essa palavra numa acepção humanístico-pragmática e não, como faz a filosofia racionalista tradicional, entendendo a verdade como certeza e como correspondência. Para o neopragmatista, devemos abandonar de uma vez por todas a busca por uma teoria geral da representação ou por uma teoria geral da linguagem; da mesma forma, transladando essa concepção ao âmbito literário, também deveríamos desobrigar-nos das sucessivas tentativas de criar uma teoria geral exclusivista da interpretação e da crítica literárias, ou da busca de uma metodologia monista e definitiva: a crítica é uma atividade plural e que atende a diversas demandas e objetivos

  14. The "dirty weather" diaries of Reverend Richard Davis: insights about early colonial-era meteorology and climate variability for northern New Zealand, 1839-1851

    Reverend Richard Davis (1790-1863) was a colonial-era missionary stationed in the Far North of New Zealand who was a key figure in the early efforts of the Church Mission Society. He kept meticulous meteorological records for the early settlements of Waimate North and Kaikohe, and his observations are preserved in a two-volume set in the Sir George Grey Special Collections in the Auckland Central Library. The Davis diary volumes are significant because they constitute some of the earliest land-based meteorological measurements that were continually chronicled for New Zealand. The diary measurements cover nine years within the 1839-1851 time span that are broken into two parts: 1839-1844 and 1848-1851. Davis' meteorological recordings include daily 9 a.m. and noon temperatures and midday pressure measurements. Qualitative comments in the diary note prevailing wind flow, wind strength, cloud cover, climate variability impacts, bio-indicators suggestive of drought, and notes on extreme weather events. "Dirty weather" comments scattered throughout the diary describe disturbed conditions with strong winds and driving rainfall. The Davis diary entries coincide with the end of the Little Ice Age (LIA) and they indicate southerly and westerly circulation influences and cooler winter temperatures were more frequent than today. A comparison of climate field reconstructions derived from the Davis diary data and tree-ring-based winter temperature reconstructions are supported by tropical coral palaeotemperature evidence. Davis' pressure measurements were corroborated using ship log data from vessels associated with iconic Antarctic exploration voyages that were anchored in the Bay of Islands, and suggest the pressure series he recorded are robust and can be used as "station data". The Reverend Davis meteorological data are expected to make a significant contribution to the Atmospheric Circulation Reconstructions across the Earth (ACRE) project, which feeds the major data

    Full Text Available It is usually said that the memory of the war period had been completely reversed in the former Soviet borderlands since the collapse of the USSR, turning former “traitors” into heroes or victims. However, attempts to set up a new approach of the Nazi occupation and collaboration are rooted in the “Thaw” period. I remember everything, Richard – dealing with the Latvian legion, started to be considered in 1957. That coincided both with the massive return of the Latvian deportees from Siberia, and with a renewal of trials against war criminals. Produced only in 1966, the film reflected the social tensions going along with the sensitive topic, and presented a point of view far more nuanced than the official figure of the “Latvian traitor” imposed during the Stalinist period. Based on interviews, archival material and film analysis, this article aims at understanding through the film-making process the connection between the deep changes of the political meaning of the war period, and the social composition of film production.

    Full Text Available Happiness and lament in the house of Jacob The birth narrative in Genesis 29:31-30:24 is a coherent mini drama in its own right, although it is embedded in the patriarchal narratives and as such furnishes important background to the unfolding drama in Jacob's house. In this narrative, the reader is invited right into the intricate family relations of a dysfunctional polygamous marriage, where two rivals communicate with each other and their mutual husband by means of the names given at birth to their children and the children of their slave girls. This article focuses on the quest for happiness, which is evident in the births and name-giving in the house of Jacob. Although true happiness remains elusive, at the end both women receive their dues. God keeps a balance between the two contenders, but the birth of Rachel’s son calls for a resolution still to come. The text is thus left open ended.
