  2. Archie's law - a reappraisal

    Science.gov (United States)

    Glover, Paul W. J.

    2016-07-01

    When scientists apply Archie's first law they often include an extra parameter a, which was introduced about 10 years after the equation's first publication by Winsauer et al. (1952), and which is sometimes called the "tortuosity" or "lithology" parameter. This parameter is not, however, theoretically justified. Paradoxically, the Winsauer et al. (1952) form of Archie's law often performs better than the original, more theoretically correct version. The difference in the cementation exponent calculated from these two forms of Archie's law is important, and can lead to a misestimation of reserves by at least 20 % for typical reservoir parameter values. We have examined the apparent paradox, and conclude that while the theoretical form of the law is correct, the data that we have been analysing with Archie's law have been in error. There are at least three types of systematic error that are present in most measurements: (i) a porosity error, (ii) a pore fluid salinity error, and (iii) a temperature error. Each of these systematic errors is sufficient to ensure that a non-unity value of the parameter a is required in order to fit the electrical data well. Fortunately, the inclusion of this parameter in the fit has compensated for the presence of the systematic errors in the electrical and porosity data, leading to a value of cementation exponent that is correct. The exceptions are those cementation exponents that have been calculated for individual core plugs. We make a number of recommendations for reducing the systematic errors that contribute to the problem and suggest that the value of the parameter a may now be used as an indication of data quality.

  9. A new theoretical interpretation of Archie's saturation exponent

    Directory of Open Access Journals (Sweden)

    P. W. J. Glover

    2017-07-01

    Full Text Available This paper describes the extension of the concepts of connectedness and conservation of connectedness that underlie the generalized Archie's law for n phases to the interpretation of the saturation exponent. It is shown that the saturation exponent as defined originally by Archie arises naturally from the generalized Archie's law. In the generalized Archie's law the saturation exponent of any given phase can be thought of as formally the same as the phase (i.e. cementation exponent, but with respect to a reference subset of phases in a larger n-phase medium. Furthermore, the connectedness of each of the phases occupying a reference subset of an n-phase medium can be related to the connectedness of the subset itself by Gi = GrefSini. This leads naturally to the idea of the term Sini for each phase i being a fractional connectedness, where the fractional connectednesses of any given reference subset sum to unity in the same way that the connectednesses sum to unity for the whole medium. One of the implications of this theory is that the saturation exponent of any phase can be now be interpreted as the rate of change of the fractional connectedness with saturation and connectivity within the reference subset.

    Science.gov (United States)

    Askheim, Clemet; Sandset, Tony; Engebretsen, Eivind

    2017-03-01

    Over the last 20 years, the evidence-based medicine (EBM) movement has sought to develop standardised approaches to patient treatment by drawing on research results from randomised controlled trials (RCTs). The Cochrane Collaboration and its eponym, Archie Cochrane, have become symbols of this development, and Cochrane's book Effectiveness and Efficiency from 1972 is often referred to as the first sketch of what was to become EBM. In this article, we claim that this construction of EBM's historical roots is based on a selective reading of Cochrane's text. Through a close reading of this text, we show that the principal aim of modern EBM, namely to warrant clinical decisions based on evidence drawn from RCTs, is not part of Cochrane's original project. He had more modest ambitions for what RCTs can accomplish, and, more importantly, he was more concerned with care and equality than are his followers in the EBM movement. We try to reconstruct some of Cochrane's lost legacy and to articulate some of the important silences in Effectiveness and Efficiency From these clues it might be possible, we argue, to remodel EBM in a broader, more pluralistic, more democratic and less authoritarian manner.

    2002-06-01

    Clinical trials constitute a key source of medical research and are therefore conducted on a regular basis at university hospitals. The professional execution of trials requires, among other things, a repertoire of tools that support efficient data management. Tasks that are essential for efficient data management in clinical trials include the following: the design of the trial database, the design of electronic case report forms, recruiting patients, collection of data, and statistical analysis. The present article reports the manner in which these tasks are supported by the ArchiMed system at the University of Vienna and Graz Medical Schools. ArchiMed is customized for clinical end users, allowing them to autonomously manage their clinical trials without having to consult computer experts. An evaluation of the ArchiMed system in 12 trials recently conducted at the University of Vienna Medical School shows that the individual system functions can be usefully applied for data management in clinical trials.

  2. Archie's Saturation Exponent for Natural Gas Hydrate in Coarse-Grained Reservoirs

    Science.gov (United States)

    Cook, Ann E.; Waite, William F.

    2018-03-01

    Accurately quantifying the amount of naturally occurring gas hydrate in marine and permafrost environments is important for assessing its resource potential and understanding the role of gas hydrate in the global carbon cycle. Electrical resistivity well logs are often used to calculate gas hydrate saturations, Sh, using Archie's equation. Archie's equation, in turn, relies on an empirical saturation parameter, n. Though n = 1.9 has been measured for ice-bearing sands and is widely used within the hydrate community, it is highly questionable if this n value is appropriate for hydrate-bearing sands. In this work, we calibrate n for hydrate-bearing sands from the Canadian permafrost gas hydrate research well, Mallik 5L-38, by establishing an independent downhole Sh profile based on compressional-wave velocity log data. Using the independently determined Sh profile and colocated electrical resistivity and bulk density logs, Archie's saturation equation is solved for n, and uncertainty is tracked throughout the iterative process. In addition to the Mallik 5L-38 well, we also apply this method to two marine, coarse-grained reservoirs from the northern Gulf of Mexico Gas Hydrate Joint Industry Project: Walker Ridge 313-H and Green Canyon 955-H. All locations yield similar results, each suggesting n ≈ 2.5 ± 0.5. Thus, for the coarse-grained hydrate bearing (Sh > 0.4) of greatest interest as potential energy resources, we suggest that n = 2.5 ± 0.5 should be applied in Archie's equation for either marine or permafrost gas hydrate settings if independent estimates of n are not available.

    Science.gov (United States)

    1994-01-01

    Sandra Postel, of the Worldwatch Institute, believes that inequalities in consumption and income foster environmental degradation. The richest 20% are getting richer and consuming excessively. The bottom 20%, comprising about 1 billion people, are getting poorer and are degrading their environment in order to survive. Per capita availability of resources is continually being reduced. If there is a desire to improve the quality of life for the poorest segment of the world population, then the richest must forfeit something. Environmental taxation could reduce excessive consumption in general; this strategy would be the most efficient and useful. Taxes would be placed on pollution and resources in danger of depletion; income taxes could be reduced to balance the impact of increased taxes on the economy. Wealthy countries must make a renewed commitment to poverty alleviation and to realistic sustainable development. Aid budgets should no longer reflect military priorities or strategic objectives. Trade is clearly related to the environment and poverty, and these connections must be made publicly known. National and international trade policies must deal with poverty issues and not contribute to further environmental destruction. Eliminating debt problems is another problem in need of change. The World Bank and structural adjustment policies have not proved to be environmentally sound and have not benefitted the poor. Evaluation of programs is needed, and lending policies should reflect the growing awareness of the problems of the poor and environmental consequences. Consumption of energy, wood, paper, and water are all higher among industrialized wealthy countries. Technology needs to be applied to maximize resource use, and policies must reflect this commitment. Israel has set a good example with water consumption reduction through advanced technology.

  5. Investigating textural controls on Archie's porosity exponent using process-based, pore-scale modelling

    Science.gov (United States)

    Niu, Q.; Zhang, C.

    2017-12-01

    Archie's law is an important empirical relationship linking the electrical resistivity of geological materials to their porosity. It has been found experimentally that the porosity exponent m in Archie's law in sedimentary rocks might be related to the degree of cementation, and therefore m is termed as "cementation factor" in most literatures. Despite it has been known for many years, there is lack of well-accepted physical interpretations of the porosity exponent. Some theoretical and experimental evidences have also shown that m may be controlled by the particle and/or pore shape. In this study, we conduct a pore-scale modeling of the porosity exponent that incorporates different geological processes. The evolution of m of eight synthetic samples with different particle sizes and shapes are calculated during two geological processes, i.e., compaction and cementation. The numerical results show that in dilute conditions, m is controlled by the particle shape. As the samples deviate from dilute conditions, m increases gradually due to the strong interaction between particles. When the samples are at static equilibrium, m is noticeably larger than its values at dilution condition. The numerical simulation results also show that both geological compaction and cementation induce a significant increase in m. In addition, the geometric characteristics of these samples (e.g., pore space/throat size, and their distributions) during compaction and cementation are also calculated. Preliminary analysis shows a unique correlation between the pore size broadness and porosity exponent for all eight samples. However, such a correlation is not found between m and other geometric characteristics.

  8. Physical Explanation of Archie's Porosity Exponent in Granular Materials: A Process-Based, Pore-Scale Numerical Study

    Science.gov (United States)

    Niu, Qifei; Zhang, Chi

    2018-02-01

    The empirical Archie's law has been widely used in geosciences and engineering to explain the measured electrical resistivity of many geological materials, but its physical basis has not been fully understood yet. In this study, we use a pore-scale numerical approach combining discrete element-finite difference methods to study Archie's porosity exponent m of granular materials over a wide porosity range. Numerical results reveal that at dilute states (e.g., porosity ϕ > 65%), m is exclusively related to the particle shape and orientation. As the porosity decreases, the electric flow in pore space concentrates progressively near particle contacts and m increases continuously in response to the intensified nonuniformity of the local electrical field. It is also found that the increase in m is universally correlated with the volume fraction of pore throats for all the samples regardless of their particle shapes, particle size range, and porosities.

    Quantifying plant morphology is a very challenging task that requires methods able to capture the geometry and topology of plant organs at various spatial scales. Recently, the use of persistent homology as a mathematical framework to quantify plant morphology has been successfully demonstrated for leaves, shoots, and root systems. In this paper, we present a new data analysis pipeline implemented in the R package archiDART to analyse root system architectures using persistent homology. In addition, we also show that both geometric and topological descriptors are necessary to accurately compare root systems and assess their natural complexity.

  12. Towards plug-and-play integration of archetypes into legacy electronic health record systems: the ArchiMed experience.

    2013-01-22

    The dual model approach represents a promising solution for achieving semantically interoperable standardized electronic health record (EHR) exchange. Its acceptance, however, will depend on the effort required for integrating archetypes into legacy EHR systems. We propose a corresponding approach that: (a) automatically generates entry forms in legacy EHR systems from archetypes; and (b) allows the immediate export of EHR documents that are recorded via the generated forms and stored in the EHR systems' internal format as standardized and archetype-compliant EHR extracts. As a prerequisite for applying our approach, we define a set of basic requirements for the EHR systems. We tested our approach with an EHR system called ArchiMed and were able to successfully integrate 15 archetypes from a test set of 27. For 12 archetypes, the form generation failed owing to a particular type of complex structure (multiple repeating subnodes), which was prescribed by the archetypes but not supported by ArchiMed's data model. Our experiences show that archetypes should be customized based on the planned application scenario before their integration. This would allow problematic structures to be dissolved and irrelevant optional archetype nodes to be removed. For customization of archetypes, openEHR templates or specialized archetypes may be employed. Gaps in the data types or terminological features supported by an EHR system will often not preclude integration of the relevant archetypes. More work needs to be done on the usability of the generated forms.

  15. Large-scale depositional characteristics of the Ulleung Basin and its impact on electrical resistivity and Archie-parameters for gas hydrate saturation estimates

    Riedel, Michael; Collett, Timothy S.; Kim, H.-S.; Bahk, J.-J.; Kim, J.-H.; Ryu, B.-J.; Kim, G.-Y.

    2013-01-01

    Gas hydrate saturation estimates were obtained from an Archie-analysis of the Logging-While-Drilling (LWD) electrical resistivity logs under consideration of the regional geological framework of sediment deposition in the Ulleung Basin, East Sea, of Korea. Porosity was determined from the LWD bulk density log and core-derived values of grain density. In situ measurements of pore-fluid salinity as well as formation temperature define a background trend for pore-fluid resistivity at each drill site. The LWD data were used to define sets of empirical Archie-constants for different depth-intervals of the logged borehole at all sites drilled during the second Ulleung Basin Gas Hydrate Drilling Expedition (UBGH2). A clustering of data with distinctly different trend-lines is evident in the cross-plot of porosity and formation factor for all sites drilled during UBGH2. The reason for the clustering is related to the difference between hemipelagic sediments (mostly covering the top ∼100 mbsf) and mass-transport deposits (MTD) and/or the occurrence of biogenic opal. For sites located in the north-eastern portion of the Ulleung Basin a set of individual Archie-parameters for a shallow depth interval (hemipelagic) and a deeper MTD zone was achieved. The deeper zone shows typically higher resistivities for the same range of porosities seen in the upper zone, reflecting a shift in sediment properties. The presence of large amounts of biogenic opal (up to and often over 50% as defined by XRD data) was especially observed at Sites UBGH2-2_1 and UBGH2-2_2 (as well as UBGH1-9 from a previous drilling expedition in 2007). The boundary between these two zones can also easily be identified in gamma-ray logs, which also show unusually low readings in the opal-rich interval. Only by incorporating different Archie-parameters for the different zones a reasonable estimate of gas hydrate saturation was achieved that also matches results from other techniques such as pore-fluid freshening

Sandra Cisneros in her Never Marry A Mexican reinterpretsLa Malinchein a more positive light and points out how women sexuality can be the site for women empowerment.By drawing on insights from feminist theories on motherhood, marriage, and incest taboo, this study identifies the way Cisneros revises the negative image of La Malinche as a dupe, passive and submissive mistress. This study identifies that Cisneros has created a strong protagonist character named Clemencia, who exerts her subjectivity and claims for her sexual agency totransgress patriarchal construction of woman passive sexuality, imposition of maternal identity as asexual mother and taboo on incestuous relationship. Cisneros’s La Malinche is no longer depicted as the victim duped by the patriarchy, but as the survivor who is able to preserve her sense of herself in the dominating patriarchal world.   DOI: https://doi.org/10.24071/llt.2015.180103

  17. LA PSICOLOGIA PARAGUAYA REPRESENTADA EN LA PSICOLOGIA DE JAMES O. WHITTAKER Y SANDRA J. WHITTAKER

    2014-01-01

    Full Text Available En 1987 los psicólogos estadounidenses James O. Whittaker y Sandra J. Whittaker publicaron la cuarta edición de su famoso libro Psicología. Este fue uno de los textos de introducción más conocidos y utilizados en América Latina y a través de él muchos miles de estudiantes aprendieron sus primeros conceptos sobre la psicología. Esta edición estaba preparada especialmente para su utilización con los alumnos de habla castellana e introducía numerosos tópicos relacionados a la psicología latinoamericana. Además incluía menciones específicas a algunos psicólogos de la región y sus contribuciones a la psicología. Uno de ellos era José de Jesús Aguirre, psicólogo y sacerdote jesuita y uno de los pioneros de la psicología profesional en el Paraguay. Aguirre aplicó la teoría del filósofo holandés Gerard Heymans y su colaborador el psiquiatra Enno Dirk Wiersma con las modificaciones que unos años más tarde introdujo el psicólogo francés René Le Senne. El propósito de la investigación era el análisis de los rasgos tipológicos característicos en la población paraguaya. Con ello, Aguirre iniciaba el estudio científico de la personalidad en el Paraguay. Este artículo estudia la importancia que corresponde asignar a la investigación de Aguirre como parte del texto introductorio de Whittaker y Whittaker. Se analizan los fundamentos teóricos de la tipología de Heymans-Wiersma-Le Senne y las adaptaciones realizadas por Aguirre, además de su aplicación a una muestra superior a las setecientas personas. Esta provenía de diversos niveles educativos, tanto secundarios como universitarios. En la parte concluyente se analiza la relevancia de Aguirre y su trabajo en el contexto de la psicología paraguaya y latinoamericana.

  20. Sandra Cisneros’s The House on Mango Street: (Collective Memory Resonating from “the Barrio”

    Full Text Available  “The people I wrote about were real, for the most part, from here and there, now and then, but sometimes three real people would be braided together into one made-up person… I cut apart and stitched together events to tailor the story, gave it shape so it had a beginning, middle, and end, because real life stories rarely come to us complete. Emotions, though, can’t be invented, can’t be borrowed. All the emotions my characters feel, good or bad are mine.” (xxiii Although Sandra Cisneros draws on autobiographical elements in The House on Mango Street (1984, her novella does not stand for an autobiography, but it rather represents a collage of events, characters, and places that independently from one another constitute vignettes. These vignettes are not necessarily chronologically related, yet they make up a whole of voices, stories, colors, and movements that once reverberated along Mango Street. Through her (Cisneros’s stories, Esperanza Cordero’s stories, and Esperanza’s neighbors’ stories, Cisneros conveys the Southwestern Latino experience of the big city and the streets, of the barrios that is. Taking my cue from Cisneros’s “The House on Mango Street,” I will try to examine how personal experiences become memories and those memories transcend into stories. Is what comes from experience and memory that makes writing strong, powerful, persuasive, and to a certain extent relatable? Have Cisneros’s memories, reflected in Esperanza’s living experience and language contributed to the Latino’s collective memory of the life in the barrios coupled with racism, poverty and shame? On that note, I shall see how Maurice Halbwachs’s concept of collective memory applies to Cisneros’ story and the Latino experience, where Latinos’ memory is dependent upon the life in the barrio within which the majority were/are situated.

    Directory of Open Access Journals (Sweden)

    Antonádia Borges

    2015-08-01

    Full Text Available ResumoNosso texto se debruça sobre os escritos etnológicos de Archie Mafeje. Este autor sul-africano que viveu boa parte de sua carreira acadêmica no exílio, formulou críticas contundentes às ciências sociais em geral e à antropologia em particular. Para ele, formações sociais que desafiam nossas abordagens taxonômicas e dualistas, continuam sendo encarceradas em escaninhos estreitos e claustrofóbicos, em abordagens voltadas para a classificação e a interpretação do Outro. Esta ideia de alteridade baseia-se em uma leitura teórica que segrega o sujeito do objeto de escrutínio, da análise social. Em trabalhos que apontam os equívocos de estudos antropológicos, históricos e de sociologia urbana no continente africano, Mafeje demonstra como as apostas epistemológicas das ciências sociais legitimaram ideias e ideais de sociedades imóveis, circunscritas a limites territoriais demarcados no período colonial. Em suma, temos confinados o Outro, ao mesmo tempo em que temos nos satisfeito com modelos analíticos que perversamente permitiram o avanço da expropriação de terras e seus efeitos: xenofobia, êxodo, intolerância e racismo. A saída para Mafeje estaria no estabelecimento de uma interlocução autêntica, fundada não numa divisão entre o Eu e o Outro, mas no que ele chama de ontologia combativa. Segundo o autor, ao fazer etnografia, estaríamos recompondo o mundo para além dos dualismos e das cisões. Com tal proposta, Mafeje defende um projeto pós-antropológico de produção de conhecimento.

Este proceso se produce en un contexto transnacional, en el que los límites entre países vecinos quedan cada vez más difusos. En este sentido, el artículo examina la reescritura de la memoria nacional desde la perspectiva de unos actantes determinados, esto es, de unos personajes en continuo tránsito entre fronteras.

    Full Text Available The article deals with the main female characters that appear in Sandra Cisneros' collection of vignettes, House on Mango Street (1991. It sheds light on their lives and motives for their actions, through social criticism of Gloria Anzaldúa and the main points she establishes in her semi-autobiographical collection of essays Borderlands: La Frontera (1999. The topics Anzaldúa addresses give an insight into the Chicano identity, and the struggle of Chicano women in particular. Through her vantage point, I discuss gender roles, the immigrants' search for identity and their quest for a more dignified life, by trying to reconcile the antagonizing forces of the different parts of their identity.

    2012-08-01

    Full Text Available This paper discusses the short story ‘El arroyo de la Llorona’ by female Mexican-American writer Sandra Cisneros. In it the main character, Cleófilas, is subject to social, emotional and economic dependence on her husband, according to the cultural constructs on female identity that are still relevant in Latin-American patriarchal societies. Due to her circumstances of complete marginalisation and domestic violence, Cleófilas chooses to avoid reality, and this avoidance not only costs her mental well-being,but also annuls her will to make changes to her suffocating life. Oppressed by a patriarchal system,Cleófilas develops an unusual interest in the Llorona legend and, through the remembrance of this myth, these two female figures become symbols of resistance and liberation. In the story, the Llorona ceases to be the denigrated woman tradition has always made her out to be, and becomes the image of a contemporary heroine capable of challenging radical patriarchal norms.

    Full Text Available The paper considers application and development of information technologies while carrying out project management in construction. Organizational and technological support of works throughout its life cycle exerts an influence on quality and efficiency of successful implementation of the construction project. In order to achieve the project goal it is necessary perfectly to organize and plan works, distribute roles and responsibilities of the project participants, regulate composition and content of the project documentation. While analyzing technical and economic indices of construction organization activity and management systems operating in these organizations, conclusion has been made that market experience in functioning of operational management systems has not been adequately applied in practice of domestic construction organizations. Thus, introduction of integrated management systems for quality, costs, time parameters pertaining to project construction, their resource support will contribute to improvement of economic situation of construction organizations. The solution consists in application of up-to-date information technologies, maximum implementation of computer systems and programs in the sphere of production, creation of application software. It has been shown that it is necessary to develop a software model that provides a possibility comprehensively to apply information technology tools for monitoring progress of construction and installation works, systematization of information technology application that allow to control key parameters of construction and installation works, improvement of system for providing actual information in project implementation process. An example of complex application of software products Primavera P6 Professional R8.3.2 and ArchiCAD 17.0.0 is given in the paper.

  5. [Mental health: an identification of new directions walking in Archie Cochrane footsteps].

    Science.gov (United States)

    Tansella, Michele

    2006-10-01

    New borders and promising new directions in scientific fields are often difficult to identify and define. This paper attempts to it so in relation to recent developments and new research evidence in mental health, recognizing that this exercise may be biased by many factors, including: the author's own perspective, professional background and research training and the always present dialectic between the analysis of the past and the attraction of the future. A good starting point is the ground-breaking work by Sir Archibald Cochrane. He recommended to adopt a rigorous and continuous evaluation of clinical practice and protocols, promoting well designed clinical research and the use of scientific methods. This evidence-based approach should also be used in mental health. High quality research, continuous education and good clinical practice, incorporating the results of scientific experiments and observations, represent the approach that ensures an improvement in care provision and patient satisfaction. Currently, mental health care is still too "opinion oriented", due to the over emphasis placed on personal experience and traditional approaches by many psychiatrists. In this paper some of the most promising recent results in psychosocial research, psychopharmacological studies and genetics, as well as in neuroimaging studies, are briefly summarised. From a pragmatic point of view, it is possible to achieve a significant improvement in the quality of mental health care if the following procedure is followed: firstly, to start from solid evidence; secondly, to promote the wide implementation of evidence-based research into every day practice; thirdly, to ensure that administrators and policy makers incorporate the available scientific evidence in the planning and evaluating services and mental health systems of care. The integration between research, education and practice remains the hardest border to cross, yet the achievement of it holds the greatest promise for better mental health care in the future.

    Full Text Available No início de 2012, em um painel de alto nível da ONU sobre “Sustentabilidade Global”, os 22 líderes mundiais que redigiram o relatório Pessoas Resilientes, Planeta Resiliente: o caminho que vale a pena seguir - debatido também na Rio + 20 - argumentaram que as mulheres são fundamentais para o desenvolvimento sustentável. Mas, alertaram que, para valorizar esse papel, a igualdade de gênero e o empoderamento das mulheres devem alcançar uma dimensão mais significativa no âmbito econômico. “A persistente desigualdade de gênero tem que ser abordada como parte de qualquer virada séria em direção ao desenvolvimento sustentável”, afirmou o painel. Infelizmente, fora das recomendações de órgãos como a ONU, a realidade ainda está longe de ser a ideal. No mundo atual, mulheres de todas as idades, culturas e condições sociais enfrentam os maiores desafios socioeconômicos e culturais.

  6. ETHNICIZING WOMEN’S DOMESTIC ENTRAPMENT IN SANDRA CISNEROS’S ANTIBILDUNGSROMAN THE HOUSE ON MANGO STREET

    Directory of Open Access Journals (Sweden)

    Lilijana Burcar

    2017-01-01

    Full Text Available The House on Mango Street has been translated into more than 20 languages worldwide, including Croatian in 2005. The novel has secured a firm foothold in many a literature and cultural studies syllabus outside the USA and has served as one of central entry points for the discussion and understanding of the position of women in America’s ethnicized communities. In its treatment of women’s disadvantaged position, Cisneros’s novel relies heavily on the tenets of liberal feminism, which reduces the understanding of gendered oppression to personal relationships between individual men and women and to the attitudes of men towards women. Unlike liberal feminist literary theory, systemic feminist literary theory takes a broader social context into consideration by directing our critical gaze to the structural forces and institutional practices that shape gendered positions and defi ne the role of women inside and outside family settings. Th e paper shows that because of its subscription to the tenets of liberal feminism, the novel ends up treating gender constraints and women’s domestication as though these were phenomena limited only to ethnicized communities. As a result, women’s marginalization comes to be construed as a marker of ethnic otherness rather than a structural problem defining and permeating American society as a whole. Through translations, these constructs are inadvertently also carried over and can be uncritically disseminated in other cultural and academic environments outside the USA. The paper therefore argues for the need for a systemic literary approach, which can function as a welcome and much needed critical intervention in social milieus not yet fully acquainted with the problematic nature of liberal feminism and the ethnicization of women’s domestic entrapment.

Extant literature focusing on how Mathematics teachers apply their metacognitive skills in the classroom, clearly distinguishes between teaching with metacognition (TwM) referring to teachers thinking about their own thinking and teaching for metacognition (TfM) which refers to teachers creating opportunities for learners to reflect on their thinking. However, in both of these cases, thinking requires ...

A review of: De Groote, Sandra L. “Questions Asked at the Virtual and Physical Health Sciences Reference Desk: How Do They Compare and What Do They Tell Us?” Medical Reference Services Quarterly 24.2 (Summer 2005: 11-23.

    2006-03-01

    Full Text Available Objective - To identify similarities and difference in the questions asked at the virtual and physical refernece desks of a helath scienmces library, in order to better undertand user needs and highlight areas for service improvement. Also to retrospectively analyze reference statistics collected over the previous six years. Design - Use study; retrospective study of reference statistics for the period July 1997 to June 2003; literature review. Setting - Large academic helath sciences library in the United States. Subjects - All questions asked at the reference and information desks, plus questions submitted to the University-wide virtual reference service and answered by a health sciences librarian, over a period of one month. The questions were asked by faculty, staff, students and members of the public. Methods - A literature review was carried out to examine the types of information/reference questions typically asked in health sciences libraries both before and after the mass introduction of remote end-user searching of online resources and the establishment of virtual reference services. Next, the reference statistics collected at the University of Illinois at Chicage (UIC Library of the Health Sciences between July 1997 and June 2003 were examined. For most of this period a digital reference service was offered using a listserv address to which patrons would submit email queries. Beginning in March 2003, a formal virtual reference service (chat and email was provided using commercial software. Finally, data was gathered on questions answered by a health sciences librarians, and clients who asked the question, at either the physical or cirtual reference desk, during the month of November 2003 at the UIC Library of the Health Sciences. Library staff completed an online survey form for each question, and if a client asked more than one question, each question was coded individually. Data included: status of client using the service (faculty/staff. undergarduate student, graduate student, non0UIC, unknown; mode of submission (email, chat, phone, in person; and type of question asked (directional, ready reference, in-depth/mediated, instructional, technical, accounts/status and other. In subsequent analysis, the original seven types of questions were further broken down into 19 categories. Main results - It was not possible to undertake a meta-analysis or systematic review of the studies identified in the literature review because of differences in time frames, settings and the categories used to code reference questions. However the following trends emerged: directional questions accounted for between 30 and 35% of questions asked at both the physical and virtual reference desks; the remainder of questions were generally about known item searched, library policies and services, research, dadabase use and quick reference. The statistics collected at UIC Library of the Health Sciences over the period July 1997 to June 2003 were analyzed. Coded reference questions fell into one of four categories; ready reference, in-depth reference, mediated searched and digital reference. There was a noticeable drop in the number of reference questions received in 1999/2000 which reflects trends reported in some of the studies identified in the literature review. The number of mediated searches decreased from 154 in 1997-98 to 4 in 2002/2003, but the number of digital reference questions increased from 0 to 508 in the same period. Statistics were collected over the month of November 2003 for 939 questions asked at the reference and information desks which included: 38 email; 48 chat; 156 phone; and 697 in person. The major findings were as follows: - appoximately 55% of questions were reference questions (33.5% ready reference, 9.7% in-depth/mediated, 9.7% instructional; 30% were directional; and 10% were technical; it is not stated what the remaining 5% of questions were; - library clients who asked the questions comprised graduate students (26%, faculty (24%, undergraduate students (24% and non-UIC patrons (22%; - all groups were most likely to ask their reference questions in person; - graduate students were the largest group of email reference (34%, undergraduates were the largest group to use chat (35% and faculty/staff were the largest group to use the telephone (39%; - 28% of the questions were answered from the library's staff's general knowledge of the library; 22% using the online catalogue or electronic journals list; 22% by referrning the patron to, or using an online database or resource; 13% by referring the patron to another department in the library (such as circulation; 7% by consulting another individual; and 5% by using print resources. Conclusion - The results of the three parts of this study - literature review, study of 1997-2003 statistics, and in-depth collection of statistics for November 2003 - are difficult to compare with each other. However, the general trend emerging from the results is that some kinds of questions asked by health sciences library clients have remained very much the same regardless of the rise of remote end-user searching and the mode of transmission of the questions. These include questions about library policies and services, journal and book holdings, database searching and instructional support. Questions about citation verification and consumer health appear to be decreasing while technical questions and questions about accessing remote databases and online journals are increasing. The majority of reference questions are still asked in person.

  15. FACTORS INFLUENCING SEXUAL HARASSMENT IN THE MALAYSIAN WORKPLACE

    Directory of Open Access Journals (Sweden)

    Lee Kum Chee

    2007-01-01

    Full Text Available This study examined the potential risks factors associated with sexually harassing behaviors within the framework of the four-factor model of sexual harassment. The factors examined are unprofessional work environment, skewed gender ratio in the workplace, knowledge of grievance procedure for sexual harassment, sexist attitudes among co-workers, privacy of workspace, physical attractiveness, dress manner of victims, job status, and sex roles. The dependent variable is incidence of sexual harassment which was evaluated using the Sexual Experience Questionnaire developed by Fitzgerald, Shullman, Bailey, Richards, Swecker, Gold, Ormerod, and Weitzman (1988. Data were collected from 657 women employees working in Malaysian organizations. The findings showed that the predictions of the four-factor model are also largely true in the case of the Malaysian workplace. The study also found that sexual harassment behaviors are fairly widespread in Malaysia.

  18. Enhanced characterization of reservoir hydrocarbon components using electromagnetic data attributes

    KAUST Repository

    Katterbauer, Klemens

    2015-12-23

    Advances in electromagnetic imaging techniques have led to the growing utilization of this technology for reservoir monitoring and exploration. These exploit the strong conductivity contrast between the hydrocarbon and water phases and have been used for mapping water front propagation in hydrocarbon reservoirs and enhancing the characterization of the reservoir formation. The conventional approach for the integration of electromagnetic data is to invert the data for saturation properties and then subsequently use the inverted properties as constraints in the history matching process. The non-uniqueness and measurement errors may however make this electromagnetic inversion problem strongly ill-posed, leading to potentially inaccurate saturation profiles. Another limitation of this approach is the uncertainty of Archie\\'s parameters in relating rock conductivity to water saturation, which may vary in the reservoir and are generally poorly known. We present an Ensemble Kalman Filter framework for efficiently integrating electromagnetic data into the history matching process and for simultaneously estimating the Archie\\'s parameters and the variance of the observation error of the electromagnetic data. We apply the proposed framework to a compositional reservoir model. We aim at assessing the relevance of EM data for estimating the different hydrocarbon components of the reservoir. The experimental results demonstrate that the individual hydrocarbon components are generally well matched, with nitrogen exhibiting the strongest improvement. The estimated observation error standard deviations are also within expected levels (between 5 and 10%), significantly contributing to the robustness of the proposed EM history matching framework. Archie\\'s parameter estimates approximate well the reference profile and assist in the accurate description of the electrical conductivity properties of the reservoir formation, hence leading to estimation accuracy improvements of around

  6. Formation factor in Bentheimer and Fontainebleau sandstones: Theory compared with pore-scale numerical simulations

    Science.gov (United States)

    Ghanbarian, Behzad; Berg, Carl F.

    2017-09-01

    Accurate quantification of formation resistivity factor F (also called formation factor) provides useful insight into connectivity and pore space topology in fully saturated porous media. In particular the formation factor has been extensively used to estimate permeability in reservoir rocks. One of the widely applied models to estimate F is Archie's law (F = ϕ- m in which ϕ is total porosity and m is cementation exponent) that is known to be valid in rocks with negligible clay content, such as clean sandstones. In this study we compare formation factors determined by percolation and effective-medium theories as well as Archie's law with numerical simulations of electrical resistivity on digital rock models. These digital models represent Bentheimer and Fontainebleau sandstones and are derived either by reconstruction or directly from micro-tomographic images. Results show that the universal quadratic power law from percolation theory accurately estimates the calculated formation factor values in network models over the entire range of porosity. However, it crosses over to the linear scaling from the effective-medium approximation at the porosity of 0.75 in grid models. We also show that the effect of critical porosity, disregarded in Archie's law, is nontrivial, and the Archie model inaccurately estimates the formation factor in low-porosity homogeneous sandstones.

  2. What is the cementation exponent? A new differential interpretation

    Science.gov (United States)

    Glover, P. W. J.

    2009-04-01

    Between 1950 and 2002 the total volume of reserves discovered has run to over 1500 Bbbl. for oil and 7.5 Tcf. for gas. Over half of these resources has already been produced, and has driven the global economy for the last fifty years. All of the assessments of the volume of hydrocarbon reserves were made using Archie's relationships (1942). It would be difficult, therefore, to overestimate the impact of either the petrophysical techniques or Archie's relationships on the worldwide economy. Archie's laws link the electrical resistivity of a rock to its porosity, to the resistivity of the water that saturates its pores, and to the fractional saturation of the pore space with the water, and are used to calculate the hydrocarbon saturation of the reservoir rock from which the reserves are then calculated. Archie's laws contain two exponents, m and n, which Archie called the cementation exponent and the saturation exponent, respectively. The conductivity of the hydrocarbon saturated rock is highly sensitive to changes in either exponent. However, despite the importance of the cementation exponent, few petrophysicists, commercial or academic, are able to describe its real physical meaning. The purpose of this contribution is to investigate the elusive physical meaning of the cementation exponent. We review the traditional interpretation of the cementation exponent and consider the extension of Archie's first law to two conducting phases. Consequently, we develop a new differential interpretation of the cementation exponent that is based on a new definition for the connectedness of the conducting phases in a porous medium. In this interpretation the connectedness of a porous medium is defined as the availability of pathways for transport, where the connectedness is the inverse of the formation resistivity factor, G = σo σw = 1 F (and may also be called the conductivity formation factor). Porosity is defined as the fractional amount of pore space in the usual manner

    The authors present measurements and computer simulation results on the electrical conductivity of nonconducting grains embedded in a conductive brine host. The shapes of the grains ranged from prolate-ellipsoidal (with an axis ratio of 5:1) through spherical to oblate-ellipsoidal (with an axis ratio of 1:5). The conductivity was studied as a function of porosity and packing, and Archie`s cementation exponent was found to depend on porosity. They used spatially regular and random configurations with aligned and nonaligned packings. The experimental results agree well with the computer simulation data. This data set will enable extensive tests of models for calculating the anisotropic conductivity of two-component systems.

    Transactional memory (TM) offers optimistic concurrency support in modern multicore archi- tectures, helping the programmers to extract parallelism in irregular applications when data dependence information is not available before runtime. In fact, recent research focus on ex- ploiting thread-level parallelism using TM approaches. However, the proposed techniques are of general use, valid for any type of application. This work presents ReduxSTM, a software TM system specially d...

    Errors in business processes result in poor data accuracy. This article proposes an architecture analysis method which utilises ArchiMate and the Probabilistic Relational Model formalism to model and analyse data accuracy. Since the resources available for architecture analysis are usually quite scarce, the method advocates interviews as the primary data collection technique. A case study demonstrates that the method yields correct data accuracy estimates and is more resource-efficient than a competing sampling-based data accuracy estimation method.

  17. Archie’s saturation exponent for natural gas hydrate in coarse-grained reservoirs

    Science.gov (United States)

    Cook, Ann E.; Waite, William F.

    2018-01-01

    Accurately quantifying the amount of naturally occurring gas hydrate in marine and permafrost environments is important for assessing its resource potential and understanding the role of gas hydrate in the global carbon cycle. Electrical resistivity well logs are often used to calculate gas hydrate saturations, Sh, using Archie's equation. Archie's equation, in turn, relies on an empirical saturation parameter, n. Though n = 1.9 has been measured for ice‐bearing sands and is widely used within the hydrate community, it is highly questionable if this n value is appropriate for hydrate‐bearing sands. In this work, we calibrate n for hydrate‐bearing sands from the Canadian permafrost gas hydrate research well, Mallik 5L‐38, by establishing an independent downhole Sh profile based on compressional‐wave velocity log data. Using the independently determined Sh profile and colocated electrical resistivity and bulk density logs, Archie's saturation equation is solved for n, and uncertainty is tracked throughout the iterative process. In addition to the Mallik 5L‐38 well, we also apply this method to two marine, coarse‐grained reservoirs from the northern Gulf of Mexico Gas Hydrate Joint Industry Project: Walker Ridge 313‐H and Green Canyon 955‐H. All locations yield similar results, each suggesting n ≈ 2.5 ± 0.5. Thus, for the coarse‐grained hydrate bearing (Sh > 0.4) of greatest interest as potential energy resources, we suggest that n = 2.5 ± 0.5 should be applied in Archie's equation for either marine or permafrost gas hydrate settings if independent estimates of n are not available.

  5. Gas hydrate saturations estimated from fractured reservoir at Site NGHP-01-10, Krishna-Godavari Basin, India

    Science.gov (United States)

    Lee, M.W.; Collett, T.S.

    2009-01-01

    During the Indian National Gas Hydrate Program Expedition 01 (NGHP-Ol), one of the richest marine gas hydrate accumulations was discovered at Site NGHP-01-10 in the Krishna-Godavari Basin. The occurrence of concentrated gas hydrate at this site is primarily controlled by the presence of fractures. Assuming the resistivity of gas hydratebearing sediments is isotropic, th?? conventional Archie analysis using the logging while drilling resistivity log yields gas hydrate saturations greater than 50% (as high as ???80%) of the pore space for the depth interval between ???25 and ???160 m below seafloor. On the other hand, gas hydrate saturations estimated from pressure cores from nearby wells were less than ???26% of the pore space. Although intrasite variability may contribute to the difference, the primary cause of the saturation difference is attributed to the anisotropic nature of the reservoir due to gas hydrate in high-angle fractures. Archie's law can be used to estimate gas hydrate saturations in anisotropic reservoir, with additional information such as elastic velocities to constrain Archie cementation parameters m and the saturation exponent n. Theory indicates that m and n depend on the direction of the measurement relative to fracture orientation, as well as depending on gas hydrate saturation. By using higher values of m and n in the resistivity analysis for fractured reservoirs, the difference between saturation estimates is significantly reduced, although a sizable difference remains. To better understand the nature of fractured reservoirs, wireline P and S wave velocities were also incorporated into the analysis.

  20. Assessment of spatial distrilbution of porosity and aquifer geohydraulic parameters in parts of the Tertiary - Quaternary hydrogeoresource of south-eastern Nigeria

    Science.gov (United States)

    George, N. J.; Akpan, A. E.; Akpan, F. S.

    2017-12-01

    An integrated attempt exploring information deduced from extensive surface resistivity study in three Local Government Areas of Akwa Ibom State, Nigeria and data from hydrogeological sources obtained from water boreholes have been explored to economically estimate porosity and coefficient of permeability/hydraulic conductivity in parts of the clastic Tertiary - Quaternary sediments of the Niger Delta region. Generally, these parameters are predominantly estimated from empirical analysis of core samples and pumping test data generated from boreholes in the laboratory. However, this analysis is not only costly and time consuming, but also limited in areal coverage. The chosen technique employs surface resistivity data, core samples and pumping test data in order to estimate porosity and aquifer hydraulic parameters (transverse resistance, hydraulic conductivity and transmissivity). In correlating the two sets of results, Porosity and hydraulic conductivity were observed to be more elevated near the riverbanks. Empirical models utilising Archie's, Waxman-Smits and Kozeny-Carman Bear relations were employed characterising the formation parameters with wonderfully deduced good fits. The effect of surface conduction occasioned by clay usually disregarded or ignored in Archie's model was estimated to be 2.58 × 10-5 Siemens. This conductance can be used as a corrective factor to the conduction values obtained from Archie's equation. Interpretation aided measures such as graphs, mathematical models and maps which geared towards realistic conclusions and interrelationship between the porosity and other aquifer parameters were generated. The values of the hydraulic conductivity estimated from Waxman-Smits model was approximately 9.6 × 10-5m/s everywhere. This revelation indicates that there is no pronounced change in the quality of the saturating fluid and the geological formations that serve as aquifers even though the porosities were varying. The deciphered parameter

  1. Rapid estimation of aquifer salinity structure from oil and gas geophysical logs

    Science.gov (United States)

    Shimabukuro, D.; Stephens, M.; Ducart, A.; Skinner, S. M.

    2016-12-01

    We describe a workflow for creating aquifer salinity maps using Archie's equation for areas that have geophysical data from oil and gas wells. We apply this method in California, where geophysical logs are available in raster format from the Division of Oil, Gas, and Geothermal Resource (DOGGR) online archive. This method should be applicable to any region where geophysical logs are readily available. Much of the work is controlled by computer code, allowing salinity estimates for new areas to be rapidly generated. For a region of interest, the DOGGR online database is scraped for wells that were logged with multi-tool suites, such as the Platform Express or Triple Combination Logging Tools. Then, well construction metadata, such as measured depth, spud date, and well orientation, is attached. The resultant local database allows a weighted criteria selection of wells that are most likely to have the shallow resistivity, deep resistivity, and density porosity measurements necessary to calculate salinity over the longest depth interval. The algorithm can be adjusted for geophysical log availability for older well fields and density of sampling. Once priority wells are identified, a student researcher team uses Neuralog software to digitize the raster geophysical logs. Total dissolved solid (TDS) concentration is then calculated in clean, wet sand intervals using the resistivity-porosity method, a modified form of Archie's equation. These sand intervals are automatically selected using a combination of spontaneous potential and the difference in shallow resistivity and deep resistivity measurements. Gamma ray logs are not used because arkosic sands common in California make it difficult to distinguish sand and shale. Computer calculation allows easy adjustment of Archie's parameters. The result is a semi-continuous TDS profile for the wells of interest. These profiles are combined and contoured using standard 3-d visualization software to yield preliminary salinity

  2. Enhanced characterization of reservoir hydrocarbon components using electromagnetic data attributes

    KAUST Repository

    Katterbauer, Klemens; Arango, Santiago; Sun, Shuyu; Hoteit, Ibrahim

    2015-01-01

    Advances in electromagnetic imaging techniques have led to the growing utilization of this technology for reservoir monitoring and exploration. These exploit the strong conductivity contrast between the hydrocarbon and water phases and have been used for mapping water front propagation in hydrocarbon reservoirs and enhancing the characterization of the reservoir formation. The conventional approach for the integration of electromagnetic data is to invert the data for saturation properties and then subsequently use the inverted properties as constraints in the history matching process. The non-uniqueness and measurement errors may however make this electromagnetic inversion problem strongly ill-posed, leading to potentially inaccurate saturation profiles. Another limitation of this approach is the uncertainty of Archie's parameters in relating rock conductivity to water saturation, which may vary in the reservoir and are generally poorly known. We present an Ensemble Kalman Filter framework for efficiently integrating electromagnetic data into the history matching process and for simultaneously estimating the Archie's parameters and the variance of the observation error of the electromagnetic data. We apply the proposed framework to a compositional reservoir model. We aim at assessing the relevance of EM data for estimating the different hydrocarbon components of the reservoir. The experimental results demonstrate that the individual hydrocarbon components are generally well matched, with nitrogen exhibiting the strongest improvement. The estimated observation error standard deviations are also within expected levels (between 5 and 10%), significantly contributing to the robustness of the proposed EM history matching framework. Archie's parameter estimates approximate well the reference profile and assist in the accurate description of the electrical conductivity properties of the reservoir formation, hence leading to estimation accuracy improvements of around 15%.

  3. Pore scale modelling of electrical and hydraulic properties of a semi-consolidated sandstone under unsaturated conditions

    Science.gov (United States)

    Cassiani, G.; dalla, E.; Brovelli, A.; Pitea, D.; Binley, A. M.

    2003-04-01

    The development of reliable constitutive laws to translate geophysical properties into hydrological ones is the fundamental step for successful applications of hydrogeophysical techniques. Many such laws have been proposed and applied, particularly with regard to two types of relationships: (a) between moisture content and dielectric properties, and (b) between electrical resistivity, rock structure and water saturation. The classical Archie's law belongs to this latter category. Archie's relationship has been widely used, starting from borehole logs applications, to translate geoelectrical measurements into estimates of saturation. However, in spite of its popularity, it remains an empirical relationship, the parameters of which must be calibrated case by case, e.g. on laboratory data. Pore-scale models have been recently recognized and used as powerful tools to investigate the constitutive relations of multiphase soils from a pore-scale point of view, because they bridge the microscopic and macroscopic scales. In this project, we develop and validate a three-dimensional pore-scale method to compute electrical properties of unsaturated and saturated porous media. First we simulate a random packing of spheres [1] that obeys the grain-size distribution and porosity of an experimental porous medium system; then we simulate primary drainage with a morphological approach [2]; finally, for each state of saturation during the drainage process, we solve the electrical conduction equation within the grain structure with a new numerical model and compute the apparent electrical resistivity of the porous medium. We apply the new method to a semi-consolidated Permo-Triassic Sandstone from the UK (Sherwood Sandstone) for which both pressure-saturation (Van Genuchten) and Archie's law parameters have been measured on laboratory samples. A comparison between simulated and measured relationships has been performed.

    Feminist Groupworkis a very thought-provoking book, although the thoughts and speculations stimulated aren't necessarily those intended. I wish that Sandra Butler and Claire Wintram had sorted out their research results with their tabula rasa in tact. When describing the effects on the female psyche of oppression, imbalance of power and exploitation, they accept continually that these stresses are confined to females.

Van Tongeren analyseerde monsters die werden genomen tijdens korte ruimtemissies naar de Russische Zvezda-module van het ISS, van 2004 tot 2007....

Many different techniques have been reported to increase the depth of field. However the main advantage in our method is its simplicity, since we propose the use of purely absorbing beam-shaping elements, which allows a high focal depth with a minimum modification of the optical archi...

Agha Ali is the claimant of negation and ambiguity in most of Sandra's opinions while emphasizing on transcendent theosophy foundations ,and he tries to make these ambiguities clear .However , Jelveh follows Avicenna's way and has the idea of criticizing Sandra .This article has chosen the problem Of immortality of subject in substantial movement between all debates of these two philosophers of the same age.in this essay we are going to survey Agha Ali's claims in his new explantation in one hand ,and survey and criticize the new explanation of Jelveh in negation Of substantial movement .One of the consequences of surveying and criticizing these two philosophers is that we recognize Agha Ali has succeeded in making Sadra's opinions clear by presenting a new explanation of substantial movement subject. However ,Jelveh has merged Sadra's opinions with Avicenna's instead of debilitating Sadra's opinions and stabilizing Avicenna's opinions.

    The aim of the present work was to characterize neurons in the archi- and neocortical white matter, and to investigate their distribution in mesial temporal sclerosis. Immunohistochemistry and quantification of neurons were performed on surgically resected tissue sections of patients with therapy-resistant temporal lobe epilepsy. Temporal lobe tissues of patients with tumor but without epilepsy and that from autopsy were used as controls. Neurons were identified with immunohistochemistry using antibodies against NeuN, calcium-binding proteins, transcription factor Tbr1 and neurofilaments. We found significantly higher density of neurons in the archi- and neocortical white matter of patients with temporal lobe epilepsy than in that of controls. Based on their morphology and neurochemical content, both excitatory and inhibitory cells were present among these neurons. A subset of neurons in the white matter was Tbr-1-immunoreactive and these neurons coexpressed NeuN and neurofilament marker SMI311R. No colocalization of Tbr1 was observed with the inhibitory neuronal markers, calcium-binding proteins. We suggest that a large population of white matter neurons comprises remnants of the subplate. Furthermore, we propose that a subset of white matter neurons was arrested during migration, highlighting the role of cortical maldevelopment in epilepsy associated with mesial temporal sclerosis.

  11. Imaging rainfall infiltration processes with the time-lapse electrical resistivity imaging method

    2017-04-01

    Electrical Resistivity Imaging (ERI) was carried out continuously for ten days to map the subsurface resistivity distribution along a potentially hazardous hillslope at the Jieshou Junior High School in Taoyuan, Taiwan. The inversions confirm the viability of ERI in tracking the movement of groundwater flow and rainfall infiltration by recording the variation of subsurface resistivity distribution. Meanwhile, relative-water-saturation (RWS) maps can be obtained from ERI images via Archie's Law, which provide a more intuitive reflection of the variation of subsurface rainfall infiltration and a more capable means of estimating the stability of a landslide body. What is more, we then found that the averaged RWS is significantly correlated with daily precipitation. Our observations indicate that real-time ERI is effective in monitoring subterraneous rainfall infiltration, and thereby in estimating the stability of a potential landslide body. When the agglomerate rainfall in the landslide slippage surface was infiltrated quickly without sustaining hydraulic pressure along the landslide slippage surface, the probability of landslides occurring was very low. On the contrary, the probability of landslides occurring could be increased due to the overpressure of pore fluids.

  12. Electrical conductivity of sandstone, limestone, and granite

    Energy Technology Data Exchange (ETDEWEB)

    1978-01-01

    The electrical conductivity of cylindrical cores of Westerly granite, Indiana limestone and Nugget, St Peter and Kayenta sandstones was measured at about 25/sup 0/C in vacuo, in air, and after saturation in distilled water, tap water, and 0.1 M NaCl solution. The three-electrode technique with a guard ring and the two-electrode technique without a guard ring were used. Core aspect ratio over the range of 2.00 to 0.25, as well as frequency over the range of 50 Hz to 10 kHz, influences the conductivity of all rocks, especially those measured in vacuo. Measurements from water-saturated samples using a guard ring are not appreciably different from those obtained without a guard ring. The conductivity of rocks saturated in 0.1 M NaCl solution changes least with a change in aspect ratio; for these rocks a linear relationship, known as Archie's Law, exists between log porosity and log conductivity. No simple correlation was found between those factors in rocks saturated with tap or distilled water. Thus, it appears Archie's Law is of questionable value for correlating laboratory data from rocks saturated with low-conductivity fluids.

    Full Text Available The parameters used to describe the electrical conductivity of a porous material can be used to describe also its thermal conductivity. A new relationship is developed to connect the thermal conductivity of an unsaturated porous material to the thermal conductivity of the different phases of the composite, and two electrical parameters called the first and second Archie's exponents. A good agreement is obtained between the new model and thermal conductivity measurements performed using packs of glass beads and core samples of the Callovo-Oxfordian clay-rocks at different saturations of the water phase. We showed that the three model parameters optimised to fit the new model against experimental data (namely the thermal conductivity of the solid phase and the two Archie's exponents are consistent with independent estimates. We also observed that the anisotropy of the effective thermal conductivity of the Callovo-Oxfordian clay-rock was mainly due to the anisotropy of the thermal conductivity of the solid phase.

    2017-12-01

    Full Text Available An integrated attempt exploring information deduced from extensive surface resistivity study in three Local Government Areas of Akwa Ibom State, Nigeria and data from hydrogeological sources obtained from water boreholes have been explored to economically estimate porosity and coefficient of permeability/hydraulic conductivity in parts of the clastic Tertiary – Quaternary sediments of the Niger Delta region. Generally, these parameters are predominantly estimated from empirical analysis of core samples and pumping test data generated from boreholes in the laboratory. However, this analysis is not only costly and time consuming, but also limited in areal coverage. The chosen technique employs surface resistivity data, core samples and pumping test data in order to estimate porosity and aquifer hydraulic parameters (transverse resistance, hydraulic conductivity and transmissivity. In correlating the two sets of results, Porosity and hydraulic conductivity were observed to be more elevated near the riverbanks. Empirical models utilising Archie’s, Waxman-Smits and Kozeny-Carman Bear relations were employed characterising the formation parameters with wonderfully deduced good fits. The effect of surface conduction occasioned by clay usually disregarded or ignored in Archie’s model was estimated to be 2.58 × 10−5 Siemens. This conductance can be used as a corrective factor to the conduction values obtained from Archie’s equation. Interpretation aided measures such as graphs, mathematical models and maps which geared towards realistic conclusions and interrelationship between the porosity and other aquifer parameters were generated. The values of the hydraulic conductivity estimated from Waxman-Smits model was approximately 9.6 × 10−5m/s everywhere. This revelation indicates that there is no pronounced change in the quality of the saturating fluid and the geological formations that serve as

    This study was aimed to understand the nature of the resistivity value of the sediment when it is contaminated, in order to use the information solving the obscure interpretation in the field. The pilot laboratory experiments were designed to simulate various degree of contamination and degree of saturation then observe the resulting changes in resistivity. The study was expected to get a better understanding of how various physical parameters effect the resistivity values in term of mathematic function. And also expected to apply those obtained function to a practical quantitatively interpretation. The sediment underlying the Mae-Hia Landfill consists of clay-rich material, with interfingerings of colluvium and sandy alluvium. A systematic study identified four kinds of sediment, sand, clayey sand, sandy clay, and clay. Representative sediment and leachate samples were taken from the field and returned to the laboratory. Both the physical and chemical properties of the sediments and leachate were analyzed to delineate the necessary parameters that could be used in Archie's equation. Sediment samples were mixed with various concentration of leachate solutions. Then the resistivity values were measured at various controlled steps in the saturation degree in a well- calibrated six-electrode model resistivity box. The measured resistivity values for sand, clayey sand, sandy clay when fully and partly saturated were collected, then plotted and fitted to Archie's equation, to obtain a mathematical relationship between bulk resistivity, porosity, saturation degree and resistivity of pore fluid. The results fit well to Archie's equation, and it was possible to determine all the unknown parameters representative of the sediment samples. For sand, clayey sand, sandy clay, and clay, the formation resistivity factors (F) are 2.90, 5.77, 7.85, and 7.85 with the products of cementation factor (m) and the pore geometry factors (a) (in term of -am) are 1.49, -1.63, -1.92, -2

  11. A Perspective on the Applicability of the Quadripartite Model of Corporate Social Responsibility in the Organizations of the Western Development Region, Romania

    Directory of Open Access Journals (Sweden)

    Cristina GĂNESCU

    2013-06-01

    Full Text Available This paper addresses the issues of social obligations that organizations have to society, starting from an analysis of the quadripartite model of corporate social responsibility described by Archie B. Carroll in 1979 and known by 1991 as the "pyramid of corporate social responsibility". The objective of this paper is to demonstrate that social responsibility dimensions do not exclude each other, but can in practice be approached by companies at the same time, but in different weights. A sociological survey conducted in the industrial organizations operating in the Western Development Region of Romania supports this hypothesis and, by creating a set of key factors, illustrates the reason why organizations tend to rely mainly on one or more of the specific dimensions of social responsibility. This research is, in our opinion, the first attempt to highlight the applicability of the model of social responsibility in businesses in Romania.

  12. Pore-scale analysis of electrical properties in thinly bedded rock using digital rock physics

    2014-01-01

    We investigated the electrical properties of laminated rock consist of macro-porous layers and micro-porous layers based on digital rock technology. Due to the bedding effect and anisotropy, traditional Archie equations cannot well describe the electrical behavior of laminated rock. The RI-Sw curve of laminated rock shows a nonlinear relationship. The RI-Sw curve can be divided into two linear segments with different saturation exponent. Laminated sand-shale sequences and laminated sands of different porosity or grain size will yield macroscopic electrical anisotropy. Numerical simulation and theoretical analysis lead to the conclusion that electrical anisotropy coefficient of laminated rock is a strong function of water saturation. The function curve can be divided into three segments by the turning point. Therefore, the electrical behavior of laminated rock should be considered in oil exploration and development. (paper)

    2004-05-01

    We estimate the concentration of gas hydrate at the Mallik 2L-38 research site using P- and S-wave velocities obtained from well logging and vertical seismic profiles (VSP). The theoretical velocities are obtained from a generalization of Gassmann's modulus to three phases (rock frame, gas hydrate and fluid). The dry-rock moduli are estimated from the log profiles, in sections where the rock is assumed to be fully saturated with water. We obtain hydrate concentrations up to 75%, average values of 37% and 21% from the VSP P- and S-wave velocities, respectively, and 60% and 57% from the sonic-log P- and S-wave velocities, respectively. The above averages are similar to estimations obtained from hydrate dissociation modeling and Archie methods. The estimations based on the P-wave velocities are more reliable than those based on the S-wave velocities.

  16. Good intentions and received wisdom are not good enough: the need for controlled trials in public health.

    Science.gov (United States)

    Macintyre, Sally

    2011-07-01

    In the 1970s Archie Cochrane noted that many healthcare procedures and forms of organisation lacked evidence of effectiveness and efficiency, and argued for improved methods of evaluation, moving from clinical opinion and observation to randomised controlled trials (RCTs). His arguments gradually became accepted in medicine, but there has been considerable resistance among policymakers and researchers to their application to social and public health interventions. This essay argues that opposition to RCTs in public health is often based on a false distinction between healthcare and community settings, and sometimes on a misunderstanding of the principles of RCTs in health care. It suggests that just as in medicine, good intentions and received wisdom are not a sufficient basis for making public policy and allocating public funds for social or health improvement.

    1991-01-01

    In Upper Zakum Field, the interest in horizontal drilling has continued. A second horizontal well was drilled during the second half of 1989. This necessitated running logging tools for well control and to evaluate the reservoir characteristics. The logging tool selected for this well is that of Sperry-Sun. Tools configuration and tolerance were found to fulfil SADCO's requirements and specifications. This paper reports on the services produced which included Measurement While Drilling (MWD) directional services and RLL (Recorded Lithology Logging). The RLL services cover Dual Gamma Ray (DGR), Electromagnetic Wave Resistivity (EWR) and Compensated Neutron Porosity (CN porosity). All the RLL tools were an integrated part of the Bottom Hole Drilling Assembly. Data acquired while surveying was recorded in a recording sub down-hole and retrieved when the tools were up at the surface. A PC assisted quick look interpretation was carried out using Archie's equation in shale free limestone to calculate: Effective porosity, Water Saturation and, Bulk water volume

  1. The space of vulnerability

    Full Text Available Archi-tecture has lost the reference to its prop “Archi” to develop mostly its “Tecture”: a deceitful form of nihilism, which has given full credit to a hurricane of instruments for which we know no purpose. Any distinction between city and architecture is purely contingent. Contingency is relevant but only in so far as it makes one lose any sense of scale. Many of our cities do not work because our style of life eradicates the sense of hospitality. The city becomes the place where we un-learn how to live together. Hospitality is vulnerability – the construction of vulnerability is the true beauty, the only deterrent against stupidity.

  4. Extending enterprise architecture modelling with business goals and requirements

    Science.gov (United States)

    Engelsman, Wilco; Quartel, Dick; Jonkers, Henk; van Sinderen, Marten

    2011-02-01

    The methods for enterprise architecture (EA), such as The Open Group Architecture Framework, acknowledge the importance of requirements modelling in the development of EAs. Modelling support is needed to specify, document, communicate and reason about goals and requirements. The current modelling techniques for EA focus on the products, services, processes and applications of an enterprise. In addition, techniques may be provided to describe structured requirements lists and use cases. Little support is available however for modelling the underlying motivation of EAs in terms of stakeholder concerns and the high-level goals that address these concerns. This article describes a language that supports the modelling of this motivation. The definition of the language is based on existing work on high-level goal and requirements modelling and is aligned with an existing standard for enterprise modelling: the ArchiMate language. Furthermore, the article illustrates how EA can benefit from analysis techniques from the requirements engineering domain.

  5. Electrokinetic effects and fluid permeability

    International Nuclear Information System (INIS)

    Berryman, J.G.

    2003-01-01

    Fluid permeability of porous media depends mainly on connectivity of the pore space and two physical parameters: porosity and a pertinent length-scale parameter. Electrical imaging methods typically establish connectivity and directly measure electrical conductivity, which can then often be related to porosity by Archie's law. When electrical phase measurements are made in addition to the amplitude measurements, information about the pertinent length scale can then be obtained. Since fluid permeability controls the ability to flush unwanted fluid contaminants from the subsurface, inexpensive maps of permeability could improve planning strategies for remediation efforts. Detailed knowledge of fluid permeability is also important for oil field exploitation, where knowledge of permeability distribution in three dimensions is a common requirement for petroleum reservoir simulation and analysis, as well as for estimates on the economics of recovery

    Gas and water transport in peat soil are of increasing interest because of their potentially large environmental and climatic effects under different types of land use. In this research, the water retention curve (WRC), gas diffusion coefficient (Dg) and air and water permeabilities (ka and kw......) of layers in peat soil from two profiles were measured under different moisture conditions. A two-region Archie's Law (2RAL)-type model was applied successfully to the four properties; the reference point was taken at -9.8kPa of soil-water matric potential where volume shrinkage typically started to occur....... For WRC in the very decomposed peat soil, the 2RAL saturation exponents (n) obtained for both the wetter (nw) and drier regions (nd) were smaller than those for the less decomposed peat. For Dg, the saturation exponent in the wetter region was larger than that in the drier one for all layers, which...

    1996-01-01

    While there is guidance for estimating the radiation hazards of fires (ARCHIE), there is little guidance on modeling the dispersion of hazardous materials from fires. The objective of this paper is to provide a review of the methodology used for modeling the impacts of liquid hydrocarbon pool fires. The required input variables for modeling of hydrocarbon pool fires include emission strength, emission duration, and dispersion characteristics. Methods for predicting the products of combustion including the use of literature values, test data, and thermodynamic equilibrium calculations are discussed. The use of energy balances coupled to radiative heat transfer calculations are presented as a method for determining flame temperature. Fire modeling literature is reviewed in order to determine other source release variables such as mass burn rate and duration and flame geometry

    Full Text Available American ecological poetry is a relatively recent literary phenomenon that has marked its existence within the tradition of nature poetry. It is represented by such poets as Robinson Jeffers, Gary Snyder, Archie R. Ammons, Denise Levertov, Mary Oliver and Wendell Berry. The major feature that distinguishes ecopoetry from traditional nature poetry is its distinct biocentrism that is manifested in the attitude of humility towards the world of nature and a critical approach to technological civilization posing danger to Earth’s eco-community. On the level of the ecological consciousness that it promotes, ecopoetry is inspired by such ecosophies as Benedict Spinoza’s monistic pantheism, Aldo Leopold’s earth ethics, Arne Naess’s deep ecology and James Lovelock’s concept of Gaia.

    2014-01-01

    The availability of enterprise information systems is a key concern for many organisations. This article describes a method for availability analysis based on Fault Tree Analysis and constructs from the ArchiMate enterprise architecture (EA) language. To test the quality of the method, several case-studies within the banking and electrical utility industries were performed. Input data were collected through stakeholder interviews. The results from the case studies were compared with availability of log data to determine the accuracy of the method's predictions. In the five cases where accurate log data were available, the yearly downtime estimates were within eight hours from the actual downtimes. The cost of performing the analysis was low; no case study required more than 20 man-hours of work, making the method ideal for practitioners with an interest in obtaining rapid availability estimates of their enterprise information systems.

    2010-01-01

    Analyzing and clustering documents is a complex problem. One explored method of solving this problem borrows from nature, imitating the flocking behavior of birds. One limitation of this method of document clustering is its complexity O(n2). As the number of documents grows, it becomes increasingly difficult to generate results in a reasonable amount of time. In the last few years, the graphics processing unit (GPU) has received attention for its ability to solve highly-parallel and semi-parallel problems much faster than the traditional sequential processor. In this paper, we have conducted research to exploit this archi- tecture and apply its strengths to the flocking based document clustering problem. Using the CUDA platform from NVIDIA, we developed a doc- ument flocking implementation to be run on the NVIDIA GEFORCE GPU. Performance gains ranged from thirty-six to nearly sixty times improvement of the GPU over the CPU implementation.

    Geoelectric methods of measurement are well suited for inorganic contaminants (salt, acid, lye) that affect the groundwater resistance. There are many publications on the interdependence between rock resistance and groundwater resistance. The so-called formation factor, i.e. the ratio between these two parameters, was defined by Archie already in 1942. Further research was done on the influence of clay and coarse clay on the formation factor. It was found that (especially at higher electrolyte concentrations) the dependence of rock resistance on groundwater resistance is always valid and is used in practice for assessing the groundwater resistance in petroleum prospecting. This is the theoretical basis for the use of geoelectric resistance method in the detection and mapping of soil pollution. Abandoned mining areas are quite often contaminated with residues of inorganic chemicals left over from metal extraction. Former industrial sites are often sources of groundwater contamination. The contribution presents an example from Southern Bohemia [de

    Evidence-based medicine is the conscientious and judicious use of current best knowledge in making decisions about the care of individual patients, often from well-designed, randomized, controlled trials. Authoritative medicine is the traditional approach to learning and practicing medicine, but no one authority has comprehensive scientific knowledge. Archie Cochrane proposed that every medical specialty should compile a list of all of the randomized, controlled trials within its field to be available for those who wish to know what treatments are effective. This was done first for obstetrics by a group collecting and critically analyzing all of the randomized trials and then indicating procedures every mother should have and those that no mother should have. Support during labor was used as an example. Similar groups are now active in almost all specialties, with information available on the Internet in the Cochrane Database of Systematic Reviews. Developmental-behavioral pediatrics should be part of this movement to evidence-based medicine.

    Full Text Available The Cattolica di Stilo, one of the greatest monu-ments of Calabria, is the most important example of the secular Byzantine influence on this region. The Greek cross inscribed in a square, with its five domes, denounces his connection with an archi-tectural style of oriental origin. Although built in a remote province of the Empire, the Catho-lic is not the expression of a poor art; all poetics typical of Byzantine architecture are manifested with originality. The first paragraph, written by Domenico Mediati, analyzes the geometries and correlates with contemporary buildings (X-XI cen-tury and similar in size and shape. The second paragraph, written by Marinella Arena, highlights the differences of construction compared to the theoretical form. The third paragraph, written by Daniele Colistra, reviews some representations of the monument trying to identify those who most influenced the collective imagination.

  18. Analyses of Public Utility Building - Students Designs, Aimed at their Energy Efficiency Improvement

    Science.gov (United States)

    Wołoszyn, Marek Adam

    2017-10-01

    Public utility buildings are formally, structurally and functionally complex entities. Frequently, the process of their design involves the retroactive reconsideration of energy engineering issues, once a building concept has already been completed. At that stage, minor formal corrections are made along with the design of the external layer of the building in order to satisfy applicable standards. Architecture students do the same when designing assigned public utility buildings. In order to demonstrate energy-related defects of building designs developed by students, the conduct of analyses was proposed. The completed designs of public utility buildings were examined with regard to energy efficiency of the solutions they feature through the application of the following programs: Ecotect, Vasari, and in case of simpler analyses ArchiCad program extensions were sufficient.

    2016-07-01

    Full Text Available Authorization and its enforcement, access control, have stood at the beginning of the art and science of information security, and remain being crucial pillar of security in the information technology (IT and enterprises operations. Dozens of different models of access control have been proposed. Although Enterprise Architecture as the discipline strives to support the management of IT, support for modeling access policies in enterprises is often lacking, both in terms of supporting the variety of individual models of access control nowadays used, and in terms of providing a unified ontology capable of flexibly expressing access policies for all or the most of the models. This study summarizes a number of existing models of access control, proposes a unified metamodel mapped to ArchiMate, and illustrates its use on a selection of example scenarios and two business cases.

  2. Effective diffusion coefficients and porosity values for argillaceous rocks and bentonite: measured and estimated values for the provisional safety analyses for SGT-E2

    In Stage 2 of the Sectoral Plan for Deep Geological Repositories, safety analyses have to be performed. Geochemical parameters describing the transport and retardation of radionuclides in the argillaceous rocks considered and in compacted bentonite are required. In the present report, diffusion parameters for all clay host rocks, confining units and compacted bentonite are derived. Diffusion of tritiated water (HTO), "3"6Cl"- and "2"2Na"+ was studied. The measurements gave values for effective diffusion coefficients (D_e) and diffusion accessible porosities. The general observed trend "N"aD_e > "H"T"OD_e > "C"lD_e is in agreement with the expected behaviour of the three species in clay materials: ion exchanging cations show an enhanced mobility due to surface diffusion effects and anions are slowed down due to anion exclusion. Due to the negatively charged clay surfaces, anionic species are repelled from these surfaces resulting in an accessible porosity that is smaller than the total porosity as measured with HTO. The effect of porewater composition on the diffusion of HTO, "3"6Cl"- and "2"2Na"+ in Opalinus Clay was investigated. For ionic strength (IS) values between 0.17 M and 1.07 M, no significant effect on D_e could be observed. In the case of "3"6Cl"-, no effect on the accessible porosity was observed. The anion diffusion accessible porosity equals 50-60 % of the total porosity, independent on the ionic strength of the porewater. The diffusion parameters were measured on sedimentary rocks such as chalk, clay and limestone rocks. All data could be described by one single modified version of Archie's relation (extended Archie's relation). For values of porosity greater than about 0.1, the classical Archie's relation was valid. For values smaller than 0.1, the data deviated from the classical Archie's relation; this can be explained by additional changes of tortuosity with porosity values. At high porosity values (low density rocks), the microfabric of the clay

This film, the foundation of my research, is the guideline to the reflection that I propose, since the focus of my analysis the main character of two parallel stories narrated in the film: the young Sandro Rosa do Nascimento, who becomes an archetypal figure in the social context of stories, scenarios and the testimonies shown by Padilha. As the discussion progresses, another important character for the analysis emerges: Sandra Mara Herzer (1962-1982, a young woman whose life trajectory allows me to compare the two aiming to understand how these two characters who report a serious context that causes the multiplication of a series of other stories similar to theirs. It is unquestionable that, although both have achieved international visibility, there is a multitude of invisible Sandros and Sandras, living in the streets and "caregivens" institutions for children, going through the same stages of this monstrous metamorphosis that led them desperation in the final scene of their short lives.

    The studies into stresses and deformations in the core are mainly focused on the fuel rod and the fuel assembly can. In high neutron doses austenitic steel swells and this is associated with a considerable increase in the volume of material. The SANDRA computer program is used for solving the problems of can deformations and stress during long-term reactor operation. The block for the mechanical interaction of cans is the key part of the program. The program input data include temperature distribution, fast neutron flux distribution and coolant overpressure inside the cans. Reactor operation is modelled using operating modes A, B, C which may arbitrarily be combined. Mode A computes bending deformations and the deformations of the can cross-section due to temperature dilatation in the change in temperature fields in the reactor; mode B computes deformations due to swelling and creep in long-term operation; mode C computes thermal deformations in reactor shut-down. A flowsheet is shown of program SANDRA as are examples of computed deformations. (M.S.)

    2002-01-01

    The primary purpose of this project was to evaluate and improve models for the bulk-skin temperature difference to the point where they could accurately and reliably apply under a wide variety of environmental conditions. To accomplish this goal, work was conducted in three primary areas. These included production of an archive of available data sets containing measurements of the skin and bulk temperatures and associated environmental conditions, evaluation of existing skin layer models using the compiled data archive, and additional theoretical work on the development of an improved model using the data collected under diverse environmental conditions. In this work we set the basis for a new physical model of renewal type, and propose a parameterization for the temperature difference across the cool skin of the ocean in which the effects of thermal buoyancy, wind stress, and microscale breaking are all integrated by means of the appropriate renewal time scales. Ideally, we seek to obtain a model that will accurately apply under a wide variety of environmental conditions. A summary of the work in each of these areas is included in this report. A large amount of work was accomplished under the support of this grant. The grant supported the graduate studies of Sandra Castro and the preparation of her thesis which will be completed later this year. This work led to poster presentations at the 1999 American Geophysical Union Fall Meeting and 2000 IGARSS meeting. Additional work will be presented in a talk at this year's American Meteorological Society Air-Sea Interaction Meeting this May. The grant also supported Sandra Castro during a two week experiment aboard the R/P Flip (led by Dr. Andrew Jessup of the Applied Physics Laboratory) to help obtain additional shared data sets and to provide Sandra with a fundamental understanding of the physical processes needed in the models.

You won’t get that from the Common Core Standards and their associated consortium tests, PARCC and SBAC. Despite the boisterous hype of higher, deeper, richer, more rigorous, and so on, there exists no valid evidence to support their claims of higher quality, achievement, or college readiness. There is a set of state standards and assessments, however, proven through actual experience to have raised academic achievement for students at all levels and in all curricular pathways: those used in Massachusetts from 2000 to 2011.

    Full Text Available Main goal of the research was to explore the relationship between motivation for motherhood and some of the sociodemographic variables which have been noticed as significant in the similar researches of other authors, as well as relation to the gender roles and gender identity, according to the model proposed by Sandra Bem. The study was conducted on the sample consisting of 571 female students in Belgrade. Statistically significant correlations are confirmed between motivation for motherhood and number of siblings, age of subject's mother and age of subject's mother at first birth. The highest correlation is found between motivation for motherhood and femininity. It is also proposed a preliminary questioner, as the first step of constructing an adequate instrument for measuring motivation for motherhood. The questioner is used for estimation of motivation for motherhood in this research.

    Full Text Available The economic crisis of 2008/2009 first emerged in the developed economies in 2008 and spilled over into developing countries and economies in transition through international financial and trade channels. This is the greatest financial crisis the world has faced since the Great Depression (Hanfstaengl, 2010; Sandra, 2008. At the height of the recession many feared that it would change into a depression. Banks were “unwilling to lend, credit spreads had widened sharply, stock markets had plunged and economies everywhere were stumbling” (Bustillo & Velloso, 2009:7. Some of the immediate effects of the economic recession on society included higher food prices and other living costs. Furthermore, corporations experienced reductions in their profit margins. It could reasonably be assumed that the NGO sector would suffer significantly as corporate donors and philanthropists typically contribute less during economic downturns.

    Full Text Available Matthew Weiner´s successful American TV series, Mad Men (2007, set in the 1960s in New York, unmasks the private and the public spaces of the home and the office. In these spaces, not only do the masculine protagonists interact, but also several feminine characters do as well. The three female characters (Betty, Peggy and Joan, who will be analyzed, represent the female stereotypes of this period: the idyllic housewife, the Sandra Dee prototype and the bombshell Marilyn Monroe archetype. In comparing the private and public spaces of the home and the office, these women´s sexuality and submission will be affected and influenced by the spaces they inhabit.

  19. Sciences from below: feminisms, postcolonialities, and modernities.

    Weaver, Harlan

    2010-01-01

    Sandra Harding's newest book, Sciences from Below: Feminisms, Postcolonialities, and Modernities, continues her work in feminist standpoint theory and science and technologies studies, asking how we might judge "good" science. Attentive to race, class, gender, and imperialism, Harding critically examines Northern and Southern sciences and technologies by adopting the perspective of those who see from below. This vision from the peripheries lets Harding question stories of modern scientific progress, revealing a multiplicity of "ethnosciences" and critiquing modernity itself. However, while Harding aims to produce knowledge for the North's others by emphasizing woman's experience, she fails to question the category "woman," ignoring contemporary transgender and queer scholarship. Further, it is Harding's care for the North's subjugated others that motivates her writing, revealing that the struggle to achieve the standpoint "from below" so critical to her project is fueled by what her ally Maria Puig de la Bellacasa would term not thinking from, but thinking with, or, more precisely, "thinking with care."

    Full Text Available While many philosophers speak of ‘pluralism’ within philosophy of biology, there has been little said about what such pluralism amounts to or what its underlying assumptions are. This has provoked so me anxiety about whether pluralism is compatible with their commitment to naturalism (Cussins 1992. This paper surveys three prominent pluralist positions (Sandra Mitchell and Michael Dietrich’s (2006 ‘integrative pluralism’, and both Peter Godfrey-Smith’s (1993 and Beth Preston’s (1998 pluralist analyses of functional explanations in evolutionary biology and demonstrates how all three are committed to a form of pragmatism. This analysis both clarifies the justification and grounding of pluralism and allows these pluralisms to avoid the criticisms of Cussins. I close by making some more general points about pluralism and its relationship to history and integration.

    Full Text Available This article discusses some of the principles that guide the descriptive forms of the actor-network theory (ANT of Bruno Latour and feminist standpoint theory formulated by Sandra Harding and Evelyn Fox Keller, through my research on the "Marie Curie Case". As a singular case between gender and science, the goal of thispaper is to play with ANT certainties against feminist perspective uncertainties. In the other hand, the certainties of feminist perspective are put against the uncertainties of ANT. With this counterpoint we intend to promote a reaction - in the chemical sense of the word – to the descriptive forms of the actor-network theory and feminist perspective taking away the obviousness of some of their assumptions. Doing that, we explore the moves of those reactions and their effects to the description which we do about science.

  5. A simple method for solving the Bussian equation for electrical conduction in rocks

    P. W. J. Glover

    2010-09-01

    Full Text Available One of the most general and effective models for calculating the complex electrical conductivity and relative dielectric permittivity of rocks saturated with pore fluids is that of Bussian. Unlike most models, it is non-linear and cannot be solved algebraically. Consequently, researchers use reiterating numerical routines to obtain a solution of the equation, and then only for the real part of the solution. Here we present a different approach to the solution that uses conformal mapping in the complex plane, and implements it within MapleTM. The method is simple and elegant in that it requires, for example, only 3 lines of code in MapleTM 11 and little programming experience. The approach has been shown to be as precise as using the classical reiterating bisection method for real data implemented in C++ on an ordinary desktop computer to within a probability over 1 in 109. However, the conformal mapping approach is 52 times as fast. We show once more that the Bussian equation breaks down for low fluid conductivities, but recommend it (with the modified Archie's law for use with rocks saturated with high salinity fluids when the matrix is conductive.

  6. Toward 5G software defined radio receiver front-ends

    Spiridon, Silvian

    2016-01-01

    This book introduces a new intuitive design methodology for the optimal design path for next-generation software defined radio front-ends (SDRXs). The methodology described empowers designers to "attack" the multi-standard environment in a parallel way rather than serially, providing a critical tool for any design methodology targeting 5G circuits and systems. Throughout the book the SDRX design follows the key wireless standards of the moment (i.e., GSM, WCDMA, LTE, Bluetooth, WLAN), since a receiver compatible with these standards is the most likely candidate for the first design iteration in a 5G deployment. The author explains the fundamental choice the designer has to make regarding the optimal channel selection: how much of the blockers/interferers will be filtered in the analog domain and how much will remain to be filtered in the digital domain. The system-level analysis the author describes entails the direct sampling architecture is treated as a particular case of mixer-based direct conversion archi...

  7. An electrical resistivity-based method for investigation of subsurface structure

    Resolving the spatial distribution of soil porosity within the subsurface is of great importance for understanding flow and transport within heterogeneous media. Additionally, porosity patterns can be associated with the availability of water and carbon dioxide that will drive geochemical reactions and constrain microbiological growth. The use of controlled experimentation has the potential to circumvent problems related to the external and internal variability of natural systems, while also allowing a higher degree of observability. In this study, we suggest an ERT-based method of retrieving porosity fields based on the application of Archie's law associated with an experimental procedure that can be used in laboratory-scale studies. We used a 2 cubic meter soil lysimeter, equipped with 238 electrodes distributed along its walls for testing the method. The lysimeter serves as a scaled-down version of the highly monitored artificial hillslopes at the Landscape Evolution Observatory (LEO) located at Biosphere 2 - University of Arizona. The capability of the ERT system in deriving spatially distributed patterns of porosity with respect to its several sources of uncertainty was numerically evaluated. The results will be used to produce an optimal experimental design and for assessing the reliability of experimental results. This novel approach has the potential to further resolve subsurface heterogeneity within the LEO project, and highlight the use of ERT-derived results for hydro-bio-geochemical studies.

    During the China's first gas hydrate drilling expedition -1 (GMGS-1), gas hydrate was discovered in layers ranging from 10 to 25 m above the base of gas hydrate stability zone in the Shenhu area, South China Sea. Water chemistry, electrical resistivity logs, and acoustic impedance were used to estimate gas hydrate saturations. Gas hydrate saturations estimated from the chloride concentrations range from 0 to 43% of the pore space. The higher gas hydrate saturations were present in the depth from 152 to 177 m at site SH7 and from 190 to 225 m at site SH2, respectively. Gas hydrate saturations estimated from the resistivity using Archie equation have similar trends to those from chloride concentrations. To examine the variability of gas hydrate saturations away from the wells, acoustic impedances calculated from the 3 D seismic data using constrained sparse inversion method were used. Well logs acquired at site SH7 were incorporated into the inversion by establishing a relation between the water-filled porosity, calculated using gas hydrate saturations estimated from the resistivity logs, and the acoustic impedance, calculated from density and velocity logs. Gas hydrate saturations estimated from acoustic impedance of seismic data are ???10-23% of the pore space and are comparable to those estimated from the well logs. The uncertainties in estimated gas hydrate saturations from seismic acoustic impedances were mainly from uncertainties associated with inverted acoustic impedance, the empirical relation between the water-filled porosities and acoustic impedances, and assumed background resistivity. ?? 2011 Elsevier Ltd.

    2017-04-01

    The limbic lobe defined by Broca is a cortical region with highly diverse structure and functions, and comprises the paleo-, archi-, and neocortices as well as their transitional zones. In the limbic lobe, Brodmann designated areas 27, 28, 34, 35, and 36 adjacent to the hippocampus, and areas 23, 24, 25, 26, 29, 30, 31, 32, and 33 around the corpus callosum. In the current literature, areas 27 and 28 correspond to the presubiculum and entorhinal cortex, respectively. Area 34 represents the cortico-medial part of the amygdaloid complex. Areas 35 and 36 roughly cover the perirhinal and parahippocampal cortices. Areas 24, 25, 32, and 33 belong to the anterior cingulate gyrus, while areas 23, 26, 29, 30, and 31 to the posterior cingulate gyrus. Areas 25, 32, and the anteroinferior portion of area 24 are deeply involved in emotional responses, particularly in their autonomic functions, through reciprocal connections with the amygdaloid complex, anterior thalamus and projections to the brainstem and spinal visceral centers. Areas 29 and 30 have dense reciprocal connections with areas 23 and 31, the dorsolateral prefrontal areas, and the regions related to the hippocampus. They play pivotal roles in mediating spatial cognition, working memory processing, and episodic memory formation.

  11. Electrical conductivity modeling in fractal non-saturated porous media

    Wei, W.; Cai, J.; Hu, X.; Han, Q.

    2016-12-01

    The variety of electrical conductivity in non-saturated conditions is important to study electric conduction in natural sedimentary rocks. The electrical conductivity in completely saturated porous media is a porosity-function representing the complex connected behavior of single conducting phases (pore fluid). For partially saturated conditions, the electrical conductivity becomes even more complicated since the connectedness of pore. Archie's second law is an empirical electrical conductivity-porosity and -saturation model that has been used to predict the formation factor of non-saturated porous rock. However, the physical interpretation of its parameters, e.g., the cementation exponent m and the saturation exponent n, remains questionable. On basis of our previous work, we combine the pore-solid fractal (PSF) model to build an electrical conductivity model in non-saturated porous media. Our theoretical porosity- and saturation-dependent models contain endmember properties, such as fluid electrical conductivities, pore fractal dimension and tortuosity fractal dimension (representing the complex degree of electrical flowing path). We find the presented model with non-saturation-dependent electrical conductivity datasets indicate excellent match between theory and experiments. This means the value of pore fractal dimension and tortuosity fractal dimension change from medium to medium and depends not only on geometrical properties of pore structure but also characteristics of electrical current flowing in the non-saturated porous media.

    2012-06-01

    Full Text Available Whereas the great problems of AEC industry are the management, exchange and storage of information, highlights the need to adopt new technologies to support the design process in the industry. The need to produce increasingly complex projects, more detailed and in an area of increasingly short time requires high precision and high speed data exchange information. There is, thus, the BIM concept as a potential tool for addressing these barriers. By using this model, which is collaborative, the professionals are involved in different phases of development: project design, planning, budgeting and construction. This paper investigates whether the architect of Curitiba, in his practice, knows the technology tools that use this concept, and makes use of them. When it appears that most professionals have never had any contact with BIM software, highlights the need for the dissemination of this concept and the facilities it can offer the professional AEC. Such facilities can be identified by improving visualization of the object modeled and increasing productivity, integrating information from multiple projects in a single digital model, as it can beverified in ArchiCAD and Revit software.

  13. New Experimental Approach for Studying Diffusion through an Intact and Unsaturated Medium: A Case Study with Callovo-Oxfordian Argillite

    International Nuclear Information System (INIS)

    Savoye, S.; Puente, C.; Coelho, D.; Imbert, Ch.; Page, J.

    2010-01-01

    The diffusion of tritiated water and anionic species was studied in an unsaturated core of Callovo-Oxfordian clay-stone, which is a potential host-rock for disposal of high-level radioactive wastes. The diffusion parameters in such conditions were determined using modified through-diffusion cells in which the suction is generated by the osmosis process. This specific device leads to values of saturation degree ranging from 81% to 100%. The results show that the diffusion through unsaturated samples is clearly slower than that in fully saturated samples, with steady-state fluxes decreasing by a factor up to 7 for tritium and up to 50 for anionic species. While tritium porosity values follow volumetric water contents (from 21 to 16%), the porosity accessible to anionic species significantly decreases (from 7. 5 to 0. 7%). Such diffusive behaviors have been modeled by means of a modified Archie's law, taking into account a critical water saturation below which no tracer can percolate. These results indicate that the largest pores, which are initially affected by dehydration, would play an important role on the connectivity of the porous medium. This would especially affect anionic species diffusion behavior because they are constrained to diffuse into the largest pores first. (authors)

    2018-03-01

    This paper proposes the organization of a parallel computer system based on Graphic Processors Unit (GPU) for 3D stereo image synthesis. The development is based on the modified ray tracing method developed by the authors for fast search of tracing rays intersections with scene objects. The system allows significant increase in the productivity for the 3D stereo synthesis of photorealistic quality. The generalized procedure of 3D stereo image synthesis on the Graphics Processing Unit/Graphics Processing Clusters (GPU/GPC) is proposed. The efficiency of the proposed solutions by GPU implementation is compared with single-threaded and multithreaded implementations on the CPU. The achieved average acceleration in multi-thread implementation on the test GPU and CPU is about 7.5 and 1.6 times, respectively. Studying the influence of choosing the size and configuration of the computational Compute Unified Device Archi-tecture (CUDA) network on the computational speed shows the importance of their correct selection. The obtained experimental estimations can be significantly improved by new GPUs with a large number of processing cores and multiprocessors, as well as optimized configuration of the computing CUDA network.

  16. An innovative technique for estimating water saturation from capillary pressure in clastic reservoirs

    Adeoti, Lukumon; Ayolabi, Elijah Adebowale; James, Logan

    2017-11-01

    A major drawback of old resistivity tools is the poor vertical resolution and estimation of hydrocarbon when applying water saturation (Sw) from historical resistivity method. In this study, we have provided an alternative method called saturation height function to estimate hydrocarbon in some clastic reservoirs in the Niger Delta. The saturation height function was derived from pseudo capillary pressure curves generated using modern wells with complete log data. Our method was based on the determination of rock type from log derived porosity-permeability relationship, supported by volume of shale for its classification into different zones. Leverette-J functions were derived for each rock type. Our results show good correlation between Sw from resistivity based method and Sw from pseudo capillary pressure curves in wells with modern log data. The resistivity based model overestimates Sw in some wells while Sw from the pseudo capillary pressure curves validates and predicts more accurate Sw. In addition, the result of Sw from pseudo capillary pressure curves replaces that of resistivity based model in a well where the resistivity equipment failed. The plot of hydrocarbon pore volume (HCPV) from J-function against HCPV from Archie shows that wells with high HCPV have high sand qualities and vice versa. This was further used to predict the geometry of stratigraphic units. The model presented here freshly addresses the gap in the estimation of Sw and is applicable to reservoirs of similar rock type in other frontier basins worldwide.

    When a sand contains a large amount of silt and clay it is often difficult to detect zones that contain gas using only the Archie Saturation Relationship. However, gas may be detected in these shaly formations using certain quick-look techniques. Log examples of these are presented in this paper. The first quick-look technique is an overlay of the neutron log on a density log. The neutron log is shifted relative to the density log to make the two porosity curves track in shaly water sands. Gas-bearing intervals become readily apparent from separations of the two curves where the density porosity is reading higher than the shifted neutron porosity. The second is an overlay of a neutron log on the sonic interval-transit-time log. The sonic log is shifted so as to match the neutron log in average tight sands in the section. This method has proved to be more optimistic than the density-neutron overlay above. It will find the gas-bearing zones, but may result in testing a zone or two which is nonproductive. The third method, used when no neutron log has been run, is a crossplot of the difference, sonic porosity minus density porosity, versus gamma ray API units. This is the most unreliable of the three methods because of the difficulty of determining the end points and the slope of the line on the plot which separates the gas zones from the non-gas zones

    Enhancing the performance of SciDAC applications on petascale systems has high priority within DOE SC. As we look to the future, achieving expected levels of performance on high-end com-puting (HEC) systems is growing ever more challenging due to enormous scale, increasing archi-tectural complexity, and increasing application complexity. To address these challenges, PERI has implemented a unified, tripartite research plan encompassing: (1) performance modeling and prediction; (2) automatic performance tuning; and (3) performance engineering of high profile applications. The PERI performance modeling and prediction activity is developing and refining performance models, significantly reducing the cost of collecting the data upon which the models are based, and increasing model fidelity, speed and generality. Our primary research activity is automatic tuning (autotuning) of scientific software. This activity is spurred by the strong user preference for automatic tools and is based on previous successful activities such as ATLAS, which has automatically tuned components of the LAPACK linear algebra library, and other re-cent work on autotuning domain-specific libraries. Our third major component is application en-gagement, to which we are devoting approximately 30% of our effort to work directly with Sci-DAC-2 applications. This last activity not only helps DOE scientists meet their near-term per-formance goals, but also helps keep PERI research focused on the real challenges facing DOE computational scientists as they enter the Petascale Era.

    Full Text Available The petrophysical analysis of the early Eocene Sui Main Limestone (SML has been conducted in Kharnhak-1 well for the prospect of the hydrocarbon exploration of the Khairpur-Jacobabad High, Middle Indus Basin, Pakistan. The petrophysical analysis of SML is carried out on the basis of well logs including gamma ray, spontaneous potential, resistivity, neutron, and density logs. These analyses lead to interpreting the vertical distribution of porosity and permeability in order to measure the reservoir potential of the SML. The Archie equation was used to assess the petrophysical characteristics. The SML has good porosity and poor permeability with positive correlation coefficient between the two parameters. The average volume of shale is 18%. The log signature of SML shows dominance of carbonates (limestone. The reservoir quality of the SML in Kharnhak-1 well is such that it is 77% water saturated. The porosity (x varies inversely with formation resistivity factor (F and compressional wave velocity (Vp. However, F and Vp are directly related with each other. Thus, the electric and elastic properties of the carbonate rocks can be influenced by postdepositional alterations, which include porosity enhancement and reduction processes respectively.

    2009-01-01

    Potential recharge through thick soils in mantled sinkholes was quantified using differential electrical resistivity tomography (ERT). Conversion of time series two-dimensional (2D) ERT profiles into 2D volumetric water content profiles using a numerically optimized form of Archie's law allowed us to monitor temporal changes in water content in soil profiles up to 9 m in depth. Combining Penman-Monteith daily potential evapotranspiration (PET) and daily precipitation data with potential recharge calculations for three sinkhole transects indicates that potential recharge occurred only during brief intervals over the study period and ranged from 19% to 31% of cumulative precipitation. Spatial analysis of ERT-derived water content showed that infiltration occurred both on sinkhole flanks and in sinkhole bottoms. Results also demonstrate that mantled sinkholes can act as regions of both rapid and slow recharge. Rapid recharge is likely the result of flow through macropores (such as root casts and thin gravel layers), while slow recharge is the result of unsaturated flow through fine-grained sediments. In addition to developing a new method for quantifying potential recharge at the field scale in unsaturated conditions, we show that mantled sinkholes are an important component of storage in a karst system.

    Noninvasive geophysical estimation of soil moisture has potential to improve understanding of flow in the unsaturated zone for problems involving agricultural management, aquifer recharge, and optimization of landfill design and operations. In principle, several geophysical techniques (e.g., electrical resistivity, electromagnetic induction, and nuclear magnetic resonance) offer insight into soil moisture, but data-analysis tools are needed to "translate" geophysical results into estimates of soil moisture, consistent with (1) the uncertainty of this translation and (2) direct measurements of moisture. Although geostatistical frameworks exist for this purpose, straightforward and user-friendly tools are required to fully capitalize on the potential of geophysical information for soil-moisture estimation. Here, we present MoisturEC, a simple R program with a graphical user interface to convert measurements or images of electrical conductivity (EC) to soil moisture. Input includes EC values, point moisture estimates, and definition of either Archie parameters (based on experimental or literature values) or empirical data of moisture vs. EC. The program produces two- and three-dimensional images of moisture based on available EC and direct measurements of moisture, interpolating between measurement locations using a Tikhonov regularization approach.

    Accurate estimation of permeability is essential in reservoir characterization and in determining fluid flow in porous media which greatly assists optimize the production of a field. Some of the permeability prediction techniques such as Porosity-Permeability transforms and recently artificial intelligence and neural networks are encouraging but still show moderate to good match to core data. This could be due to limitation to homogenous media while the knowledge about geology and heterogeneity is indirectly related or absent. The use of geological information from core description as in Lithofacies which includes digenetic information show a link to permeability when categorized into rock types exposed to similar depositional environment. The objective of this paper is to develop a robust combined workflow integrating geology and petrophysics and wireline logs in an extremely heterogeneous carbonate reservoir to accurately predict permeability. Permeability prediction is carried out using pattern recognition algorithm called multi-resolution graph-based clustering (MRGC). We will bench mark the prediction results with hard data from core and well test analysis. As a result, we showed how much better improvements are achieved in the permeability prediction when geology is integrated within the analysis. Finally, we use the predicted permeability as an input parameter in J-function and correct for uncertainties in saturation calculation produced by wireline logs using the classical Archie equation. Eventually, high level of confidence in hydrocarbon volumes estimation is reached when robust permeability and saturation height functions are estimated in presence of important geological details that are petrophysically meaningful.

    This study has assessed the implementation level of Building Information Modeling (BIM) in the construction industry of Malaysia. It also investigated several computer software packages facilitating BIM and challenges affecting its implementation. Data collection for this study was carried out using questionnaire survey among the construction practitioners. 95 completed forms of questionnaire received against 150 distributed questionnaire sets from consultant, contractor and client organizations were analyzed statistically. Analysis findings indicated that the level of implementation of BIM in the construction industry of Malaysia is very low. Average index method employed to assess the effectiveness of various software packages of BIM highlighted that Bentley construction, AutoCAD and ArchiCAD are three most popular and effective software packages. Major challenges to BIM implementation are it requires enhanced collaboration, add work to a designer, interoperability and needs enhanced collaboration. For improving the level of implementing BIM in Malaysian industry, it is recommended that a flexible training program of BIM for all practitioners must be created.

    Complex electrical impedance measurements were performed on a brine-saturated Berea sandstone core while oil and CO2 were injected at different pressures and temperatures. The saturations of brine, oil, and CO2 in the core were simultaneously estimated using an X-ray computed tomography scanner. The formation factor of this Berea core and the resistivity indexes versus the brine saturations were calculated using Archie's law. The experimental results found different flow patterns of oil under different pressures and temperatures. Fingers were observed for the first experiment at 10 MPa and 40 °C. The fingers were restrained as the viscosity ratio of oil and water changed in the second (10 MPa and 25 °C) and third (5 MPa and 25 °C) experiments. The resistivity index showed an exponential increase with a decrease in brine saturation. The saturation exponent varied from 1.4 to 4.0 at different pressure and temperature conditions. During the oil injection procedure, the electrical impedance increased with oil saturation and was significantly affected by different oil distributions; therefore, the impedance varied whether the finger was remarkable or not, even if the oil saturation remained constant. During the CO2 injection steps, the impedance showed almost no change with CO2 saturation because the brine in the pores became immobile after the oil injection.

    Hydraulic conductivity is a major parameter affecting the output accuracy of groundwater flow and transport models. The most commonly used semi-empirical formula for estimating conductivity is Kozeny-Carman equation. However, this method alone does not work well with heterogeneous strata. Two important parameters, grain size and porosity, often show spatial variations at different scales. This study proposes a method for estimating conductivity distributions by combining a stochastic hydrofacies model with geophysical methods. The Markov chain model with transition probability matrix was adopted to re-construct structures of hydrofacies for deriving spatial deposit information. The geophysical and hydro-chemical data were used to estimate the porosity distribution through the Archie's law. Results show that the stochastic simulated hydrofacies model reflects the sedimentary features with an average model accuracy of 78% in comparison with borehole log data in the Chaobai alluvial fan. The estimated conductivity is reasonable and of the same order of magnitude of the outcomes of the pumping tests. The conductivity distribution is consistent with the sedimentary distributions. This study provides more reliable spatial distributions of the hydraulic parameters for further numerical modeling.

    Full Text Available This paper investigates the validity of the random walk theory in the Euro-Serbian dinar exchange rate market. We apply Andrew Lo and Archie MacKinlay's (1988 conventional variance ratio test and Jonathan Wright's (2000 non-parametric ranks and signs based variance ratio tests to the daily Euro/Serbian dinar exchange rate returns using the data from January 2005 - December 2008. Both types of variance ratio tests overwhelmingly reject the random walk hypothesis over the data span. To assess the robustness of our findings, we examine the forecasting performance of a non-linear, nonparametric model in the spirit of Francis Diebold and James Nason (1990 and find that it is able to significantly improve upon the random walk model, thus confirming the existence of foreign exchange market imperfections in a small transition economy such as Serbia. In the last part of the paper, we conduct a comparative study on how our results relate to those of other transition economies in the region.

    We propose an approach for imaging the dynamics of complex hydrological processes. The evolution of electrically conductive fluids in porous media is imaged using time-lapse electrical resistance tomography. The related dynamic inversion problem is solved using Bayesian filtering techniques, that is, it is formulated as a sequential state estimation problem in which the target is an evolving posterior probability density of the system state. The dynamical inversion framework is based on the state space representation of the system, which involves the construction of a stochastic evolution model and an observation model. The observation model used in this paper consists of the complete electrode model for ERT, with Archie's law relating saturations to electrical conductivity. The evolution model is an approximate model for simulating flow through partially saturated porous media. Unavoidable modeling and approximation errors in both the observation and evolution models are considered by computing approximate statistics for these errors. These models are then included in the construction of the posterior probability density of the estimated system state. This approximation error method allows the use of approximate - and therefore computationally efficient - observation and evolution models in the Bayesian filtering. We consider a synthetic example and show that the incorporation of an explicit model for the model uncertainties in the state space representation can yield better estimates than a frame-by-frame imaging approach.

    Vidarbha region in Maharashtra, India is witnessing a continuous decrease in orange crop due to the propagation of `Phytopthora root rot', a water mold disease. Under favorable conditions, the disease causing bacteria can attack the plant root system and propagates to the surface (where first visual impression is made), making difficult to regain the plant health. This research aims at co-relating eco-hydrological fluxes with disease sensing parameters of orange trees. Two experimental plots around a healthy-young and declined-young orange trees were selected for our analysis. A 3-dimentional electrical resistivity tomography (ERT) (Figure) was carried at each plot to quantify the soil moisture distribution at a vadose zone. Pedo-electric relations were obtained considering modified Archie's law parameters. ERT derived moisture data was validated with time domain reflectometry (TDR) point observations. Soil moisture profiles derived from ERT were observed to be differ marginally between the two plots. Disease quantification was done by estimating the density of Phytopthora spp. inoculum in soils sampled along the root zone. Identification of Phytopthora spp. was done in the laboratory using taxonomic and morphologic criteria of the colonies. Spatio-temporal profiles of soil moisture and inoculum density were then co-related to comment on the eco-hydrological fluxes contributing to the health propagation of root rot in orange tree for implementing effective water management practices.

  17. Estimation of Gas Hydrate Saturation Using Constrained Sparse Spike Inversion: Case Study from the Northern South China Sea

    2006-01-01

    Full Text Available Bottom-simulating reflectors (BSRs were observed beneath the seafloor in the northern continental margin of the South China Sea (SCS. Acoustic impedance profile was derived by Constrained Sparse Spike Inversion (CSSI method to provide information on rock properties and to estimate gas hydrate or free gas saturations in the sediments where BSRs are present. In general, gas hydrate-bearing sediments have positive impedance anomalies and free gas-bearing sediments have negative impedance anomalies. Based on well log data and Archie's equation, gas hydrate saturation can be estimated. But in regions where well log data is not available, a quantitative estimate of gas hydrate or free gas saturation is inferred by fitting the theoretical acoustic impedance to sediment impedance obtained by CSSI. Our study suggests that gas hydrate saturation in the Taixinan Basin is about 10 - 20% of the pore space, with the highest value of 50%, and free gas saturation below BSR is about 2 - 3% of the pore space, that can rise to 8 - 10% at a topographic high. The free gas is non-continuous and has low content in the southeastern slope of the Dongsha Islands. Moreover, BSR in the northern continental margin of the SCS is related to the presence of free gas. BSR is strong where free gas occurs.

    Dore, C.; Murphy, M.

    2013-02-01

    This paper outlines a new approach for generating digital heritage models from laser scan or photogrammetric data using Historic Building Information Modelling (HBIM). HBIM is a plug-in for Building Information Modelling (BIM) software that uses parametric library objects and procedural modelling techniques to automate the modelling stage. The HBIM process involves a reverse engineering solution whereby parametric interactive objects representing architectural elements are mapped onto laser scan or photogrammetric survey data. A library of parametric architectural objects has been designed from historic manuscripts and architectural pattern books. These parametric objects were built using an embedded programming language within the ArchiCAD BIM software called Geometric Description Language (GDL). Procedural modelling techniques have been implemented with the same language to create a parametric building façade which automatically combines library objects based on architectural rules and proportions. Different configurations of the façade are controlled by user parameter adjustment. The automatically positioned elements of the façade can be subsequently refined using graphical editing while overlaying the model with orthographic imagery. Along with this semi-automatic method for generating façade models, manual plotting of library objects can also be used to generate a BIM model from survey data. After the 3D model has been completed conservation documents such as plans, sections, elevations and 3D views can be automatically generated for conservation projects.

La investigación se realiza a partir de una muestra de 5863 estudiantes de secundaria, como parte de la “IV Encuesta nacional sobre consumo de drogas en población de educación secundaria”, la cual se aplicó durante el 2015 a un grupo representativo de estudiantes de 50 colegios de todo Costa Rica. El instrumento utilizado contó con 109 preguntas distribuidas en siete secciones distintas, desde información personal y académica básica, a conductas de riesgo, bajo los efectos de sustancias psicoactivas. Entre los principales resultados se encuentra que aproximadamente 6 de cada 10 estudiantes reportan un mayor involucramiento por parte de sus padres, además, se rescatan mayores niveles de prevalencia en consumo de alcohol, tabaco y marihuana entre los jóvenes con menor involucramiento parental; de igual forma, aquellos jóvenes con una mejor relación con sus padres presentan una percepción de alto riesgo mayor sobre conductas de consumo. Se encontraron también relaciones estadísticamente significativas entre el consumo de padres y su nivel de involucramiento, evidenciando que aquellos que consumen en menor medida presentan un mayor nivel de involucramiento.

  20. Is The Water Shortage Crisis Really One of the Most Dangerous?

    2010-12-01

    Author of the 1998 book, Last Oasis: Facing Water Scarcity, Dr. Sandra Postel predicts big water availability problems as populations of so-called “water-stressed” countries jump perhaps six fold over the next 30 years. The author has reported on this in his previous AGU presentations. In the next four decades, more than half of the world’s population will have to deal with sever water shortages. The United States has been blessed with several large fresh water lakes. In spite of having this fresh water supply, some states like Arizona could be facing sever fresh water shortages in the next couple of decades. Sid Wilson, general manager of the Central Arizona Project has indicated "It's not a question of if there is a water shortage anymore. It is in reality, when there will be a water shortage. " Several states share water from the Colorado river. The river has limited water supply to cater to the needs of Arizona, Nevada, California, Colorado, New Mexico, Utah and Wyoming. World Health Organization, NASA, Department of the Interior, NOAA and several organizations have observed that there is a real water shortage crisis. This is because the world’s population has tripled in the twentieth century. This has resulted in a six-fold increase of water usage. Fresh water supply is limited. This is because water cannot be replaced with an alternative. It is important to observe that petroleum can be replaced with alternative fuel resources. It is necessary to recognize that fact that irrigation necessitates almost 65% to 70% of water withdrawal. Industry may utilize about 20% and domestic consumption is about 10% Evaporation from reservoirs is also a major factor, depending upon the climate and environment. Therefore there is an urgent need for all the countries to establish a strong, sound, sensible and sustainable management program for utilizing the available water supplies efficiently (Narayanan, 2008).

    Full Text Available Resumen Objetivo: explorar la existencia de barreras de acceso a los servicios de salud en las historias de mujeres con cáncer de mama, que han recibido apoyo de seis ong colombianas. Metodología: se llevó a cabo un estudio cualitativo descriptivo interpretativo, en cinco ciudades colombianas: Bogotá, Medellín, Cali, Valledupar y Santa Marta, incluyendo 44 mujeres apoyadas por seis ong. Se realizaron grupos focales y entrevistas en profundidad. Resultados: en el proceso emergieron cuatro categorías: barreras ligadas a los determinantes estructurales, barreras originadas en los determinantes intermedios, herramientas para enfrentar las barreras y una categoría que hace referencia a la oportunidad de obtener un diagnóstico y un tratamiento de cáncer de mama. A partir de estas categorías, se propone un modelo de barreras de acceso en cáncer de mama, desde la perspectiva de los determinantes sociales. Discusión: a pesar de los esfuerzos del país por mejorar la oportunidad en prevención, diagnóstico y tratamiento del cáncer —incluyendo la promulgación de la ley 1384 de 2010 (Ley Sandra Ceballos—, las mujeres con cáncer de mama enfrentan barreras de acceso a los servicios de salud, que están determinadas socialmente, y frente a las cuales el sistema muestra cierto nivel de incapacidad.

    EMAG2013 was certainly the biggest EMAG conference I can remember in my twenty years of going to EMAG conferences. We had a total of about 180 scientific delegates, not including exhibitors. The conference also benefited from the York conference centre allowing us to integrate the scientific sessions, refreshments and exhibition in one building. This all made for a very vibrant and focused conference. The quality of the presentations was again very high and judging by many of the student talks given, there is plenty of hope for an excellent future for electron microscopy in the UK. A unique feature of this conference was a chance to organise a session to commemorate the 80th year of one of the pioneers of electron microscopy in the UK, Professor Archie Howie. An excellent symposium was organised in his honour by one of his former students, Professor Pratibha Gai of the University of York. This was dedicated to one field that he made some important initial contributions to: in-situ microscopy. The symposium gave a depth and breadth of overview to this field unusual at an EMAG conference, with speakers from the UK, Europe, Japan and the USA and gave a real taste of some of the possibilities in the latest instruments to observe real materials at work at nanometre or even atomic resolution. Professor Howie himself gave a highly entertaining retrospective of his time working in microscopy from the 1950s until the present in his talk after the conference dinner on the Thursday evening at the excellent York National Railway Museum. We also had excellent plenary lectures from Professor Wolfgang Baumeister on a topic perhaps novel to many at EMAG, TEM in Structural Biology; from Professor Prathibha Gai on atomic resolution in-situ studies of chemical reactions in the TEM; and Professor Archie Howie discussing some of the important current open questions in TEM and STEM. This proceedings therefore presents a snapshot of a broad cross-section of the exciting work going on in

    component diffusion (MCD) feature in PHREEQC made possible to take into account a chemistry feedback effect on the transport parameters via the porosity evolution. The use of the MCD option to perform such calculation has been validated with an inter-comparison with TOUGHREACT on simple systems. Preliminary results show, as expected, that to consider the porosity feedback has a strong impact on the necessary time to clog the porosity. A sensitivity analysis is currently performed on the Archie parameter (Eq. 1) in order to evaluate its impact on the extent of the degradation. At the same time taking into consideration 2D geometry in comparison to 1D has a little effect on the extend of the alkaline plume that remains spatially restricted to the zone surrounding the concrete/clay interfaces. Eq(1) D e = D w ε n , where D e is the effective diffusion coefficient, D w the diffusion coefficient of the species in water, e the porosity and n the Archie parameter. (authors)

    Document available in extended abstract form only. The main objective of the present study is to characterize the evolution of diffusion properties of porous materials as influenced by porosity changes. When under geochemical perturbation, the rocks porosity evolves with dissolution/precipitation processes. The impact of changes in porosity on the diffusion phenomena are implemented in most geochemical models using Archie's law: D e /D 0 = ε m where D e and D 0 are the effective diffusivity and the diffusivity of the element in water in m 2 s -1 , respectively, e is the overall porosity and m is the cementation factor. The factor m is a function of pores geometry and compaction. Depending on the rock considered, its value ranges from 1 to 3. Moreover, as the porosity decreases the connectivity of pores changes. At low overall porosity, the effective porosity is the determining parameter affecting effective diffusivity. Therefore, the Archie's law needs to be modified to accurately predict geochemical migration of pollutants such as radio-elements in a dynamic system. Our experimental approach is divided in two complementary parts: (i) diffusion experiments conducted in hot-laboratory using radiotracers and (ii) time-dependant monitoring of porosity evolution in three dimensions using computed tomography (CT). For the two approaches, simplified systems are used to define the co-evolution of porosity and diffusivity using a minimum number of parameters, in order to optimize the understanding of the basics and determining processes. For this purpose, three materials are used in diffusion columns: (i) rods of porous ceramic, (ii) artificial silica beads of different particle sizes (SiLi R ) and (iii) purified sea sand (Merck R ). The precipitation of simple salts, celestite (SrSO 4 ) and strontianite (SrCO 3 ), is forced in the porous material once placed in diffusion columns. Celestite and strontianite were chosen for their fast precipitation kinetics, and because

    A field experiment consisting of geophysical logging and tracer testing was conducted in a single well that penetrated a sand-and-gravel aquifer at the U.S. Geological Survey Toxic Substances Hydrology research site on Cape Cod, Massachusetts. Geophysical logs and flowmeter/pumping measurements were obtained to estimate vertical profiles of porosity ϕ, hydraulic conductivity K, temperature, and bulk electrical conductivity under background, freshwater conditions. Saline-tracer fluid was then injected into the well for 2 h and its radial migration into the surrounding deposits was monitored by recording an electromagnetic-induction log every 10 min. The field data are analyzed and interpreted primarily through the use of Archie's (1942) law to investigate the role of topological factors such as pore geometry and connectivity, and grain size and packing configuration in regulating fluid flow through these coarse-grained materials. The logs reveal no significant correlation between K and ϕ, and imply that groundwater models that link these two properties may not be useful at this site. Rather, it is the distribution and connectivity of the fluid phase as defined by formation factor F, cementation index m, and tortuosity α that primarily control the hydraulic conductivity. Results show that F correlates well with K, thereby indicating that induction logs provide qualitative information on the distribution of hydraulic conductivity. A comparison of α, which incorporates porosity data, with K produces only a slightly better correlation and further emphasizes the weak influence of the bulk value of ϕ on K.

    Weathering of rocks as a result of exposure to water and the atmosphere can cause significant changes in their chemistry and porosity. In low-porosity rocks, such as basalts, changes in porosity, resulting from chemical weathering, are likely to modify the rock's effective diffusivity and permeability, affecting the rate of solute transport and thus potentially the rate of overall weathering to the extent that transport is the rate limiting step. Changes in total porosity as a result of mineral dissolution and precipitation have typically been used to calculate effective diffusion coefficients through Archie's law for reactive transport simulations of chemical weathering, but this approach fails to account for unconnected porosity that does not contribute to transport. In this study, we combine synchrotron X-ray microcomputed tomography ({mu}CT) and laboratory and numerical diffusion experiments to examine changes in both total and effective porosity and effective diffusion coefficients across a weathering interface in a weathered basalt clast from Costa Rica. The {mu}CT data indicate that below a critical value of {approx}9%, the porosity is largely unconnected in the basalt clast. The {mu}CT data were further used to construct a numerical pore network model to determine upscaled, effective diffusivities as a function of total porosity (ranging from 3 to 30%) for comparison with diffusivities determined in laboratory tracer experiments. By using effective porosity as the scaling parameter and accounting for critical porosity, a model is developed that accurately predicts continuum-scale effective diffusivities across the weathering interface of the basalt clast.

    The Atacama Desert represents one of the driest regions on earth, and despite the absence of sustainable clean water reserves the demand has increased drastically since 1970 as a result of growing population and expanding mining activities. Magnetotelluric (MT) and Transient Electromagnetic (TEM) measurements were carried out for groundwater exploration in late 2015 in the area of the Profeta Basin at the western margin of the Chilean Precordillera. Both methods complement each other: While MT in general attains larger penetration depths, TEM allows better resolution of near surface layers; furthermore TEM is free from galvanic distortion. Data were collected along three profiles, enabling a continuous resistivity image from the surface to at least several hundred meters depth. TEM data were inverted in a 1-D manner, consistently yielding a poorly conductive near-surface layer with a thickness of approximately 30 m and below a well-conducting layer which we interpret as the aquifer with resistivities around 10 Ωm. At marginal sites of the main SW-NE-profile the resistive basement was found in 150 m. These depths are confirmed by interpretation of the MT soundings. Those were firstly inverted with a 2-D approach and then by 3-D inversion as clear indications of three-dimensionality exist. Several modeling runs were performed with different combinations of transfer functions and smoothing parameters. Generally, MT and TEM results agree reasonably well and an overall image of the resistivity structures in the Profeta Basin could be achieved. The aquifer reaches depths of more than 500 m in parts and, by applying Archie's law, resistivities of 1 Ωm can be assumed, indicating highly saline fluids from the source region of the surrounding high Andes under persisting arid conditions.

    Slope failures have become the main focus for infrastructures development on hilly areas in Malaysia especially the development of tourism and residential. Lack of understanding and information of the subsoil conditions and geotechnical issues are the main cause of the slope failures. The failures happened are due to a combination of few factors such as topography, climate, geology and land use. 2-D resistivity method was conducted at the collapsed area in Selangor. The 2-D resistivity was done to study the instability of the area. The collapsed occurred because of the subsurface materials was unstable. Pole-dipole array was used with 5 m minimum electrode spacing for the 2-D resistivity method. The data was processed using Res2Dinv software and the porosity was calculated using Archie's law equation. The results show that the saturated zone (1-100 Ωm), alluvium or highly weathered rock (100-1000 Ωm), boulders (1600-7000 Ωm) and granitic bedrock (>7000 Ωm). Generally, the slope failures or landslides occur during the wet season or after rainfall. It is because of the water infiltrate to the slope and cause the saturation of the slope which can lead to landslides. Then, the porosity of saturated zone is usually high because of the water content. The area of alluvium or highly weathered rock and saturated zone have high porosity (>20%) and the high porosity also dominated at almost all the collapsed area which means that the materials with porosity >20% is potential to be saturated, unstable and might trigger slope failures.

    Square array electrical soundings were made at 13 sites in the Biscayne Aquifer distributed between 1 and 20 km from the shoreline. These soundings were modeled to investigate how resistivity varies spatially and with depth in the upper 15 m of the aquifer. Porosity was estimated from the modeled formation resistivity and observed pore fluid resistivity with Archie's Law. The models were used to interpolate resistivity and porosity surfaces at -2, -5, -8, and -15 m elevations. Modeled resistivity in the unsaturated zone is generally higher than 300 Ω m with the resistivity at sites with thick unsaturated zones greater than 1000 Ω m. Resistivity in the saturated zone ranges from 30 to 320 Ω m. At many sites in the western portions of the study area, resistivity is constant or increases with depth whereas sites in the center of the Atlantic Coastal Ridge exhibit a distinct low resistivity zone (ρ aquifer. The estimated porosity ranges between 14% and 71% with modal values near 25%. The porosity structure varies both with depth and spatially. Western sites exhibit a high porosity zone at shallow depths best expressed in a NE-SW trending zone of 40-50% porosity situated near the western margin of the Atlantic Coastal Ridge. This zone roughly corresponds in depth with the Q5 chronostratigraphic unit of the Miami Fm. which constitutes the upper flow unit of the Biscayne Aquifer. The highest porosity (>50%) is seen at elevations below -5 m at sites in the center of the Atlantic Coastal Ridge and likely corresponds to solution features. The general NE-SW trend of the resistivity and porosity structure suggests a causal connection with the Pleistocene paleogeography and sedimentary environments.

  14. A Time Domain Update Method for Reservoir History Matching of Electromagnetic Data

    2014-03-25

    The oil & gas industry has been the backbone of the world\\'s economy in the last century and will continue to be in the decades to come. With increasing demand and conventional reservoirs depleting, new oil industry projects have become more complex and expensive, operating in areas that were previously considered impossible and uneconomical. Therefore, good reservoir management is key for the economical success of complex projects requiring the incorporation of reliable uncertainty estimates for reliable production forecasts and optimizing reservoir exploitation. Reservoir history matching has played here a key role incorporating production, seismic, electromagnetic and logging data for forecasting the development of reservoirs and its depletion. With the advances in the last decade, electromagnetic techniques, such as crosswell electromagnetic tomography, have enabled engineers to more precisely map the reservoirs and understand their evolution. Incorporating the large amount of data efficiently and reducing uncertainty in the forecasts has been one of the key challenges for reservoir management. Computing the conductivity distribution for the field for adjusting parameters in the forecasting process via solving the inverse problem has been a challenge, due to the strong ill-posedness of the inversion problem and the extensive manual calibration required, making it impossible to be included into an efficient reservoir history matching forecasting algorithm. In the presented research, we have developed a novel Finite Difference Time Domain (FDTD) based method for incorporating electromagnetic data directly into the reservoir simulator. Based on an extended Archie relationship, EM simulations are performed for both forecasted and Porosity-Saturation retrieved conductivity parameters being incorporated directly into an update step for the reservoir parameters. This novel direct update method has significant advantages such as that it overcomes the expensive and ill

    2002-01-01

    This paper presents a method for combining seismic and electromagnetic measurements to predict changes in water saturation, pressure, and CO 2 gas/oil ratio in a reservoir undergoing CO 2 flood. Crosswell seismic and electromagnetic data sets taken before and during CO 2 flooding of an oil reservoir are inverted to produce crosswell images of the change in compressional velocity, shear velocity, and electrical conductivity during a CO 2 injection pilot study. A rock properties model is developed using measured log porosity, fluid saturations, pressure, temperature, bulk density, sonic velocity, and electrical conductivity. The parameters of the rock properties model are found by an L1-norm simplex minimization of predicted and observed differences in compressional velocity and density. A separate minimization, using Archie's law, provides parameters for modeling the relations between water saturation, porosity, and the electrical conductivity. The rock-properties model is used to generate relationships between changes in geophysical parameters and changes in reservoir parameters. Electrical conductivity changes are directly mapped to changes in water saturation; estimated changes in water saturation are used along with the observed changes in shear wave velocity to predict changes in reservoir pressure. The estimation of the spatial extent and amount of CO 2 relies on first removing the effects of the water saturation and pressure changes from the observed compressional velocity changes, producing a residual compressional velocity change. This velocity change is then interpreted in terms of increases in the CO 2 /oil ratio. Resulting images of the CO 2 /oil ratio show CO 2 -rich zones that are well correlated to the location of injection perforations, with the size of these zones also correlating to the amount of injected CO 2 . The images produced by this process are better correlated to the location and amount of injected CO 2 than are any of the individual

    In 2014 an interdisciplinary survey was conducted as part of the German SUGAR project in the Western Black Sea targeting gas hydrate occurrences in the Danube Delta. Marine controlled source electromagnetic (CSEM) data were acquired with an inline seafloor-towed array (BGR), and a two-polarization horizontal ocean-bottom source and receiver configuration (GEOMAR). The CSEM data are co-located with high-resolution 2-D and 3-D seismic reflection data (GEOMAR). We present results from 2-D regularized inversion (MARE2DEM by Kerry Key), which provides a smooth model of the electrical resistivity distribution beneath the source and multiple receivers. The 2-D approach includes seafloor topography and structural constraints from seismic data. We estimate uncertainties from the regularized inversion and compare them to 1-D Bayesian inversion results. The probabilistic inversion for a layered subsurface treats the parameter values and the number of layers as unknown by applying reversible-jump Markov-chain Monte Carlo sampling. A non-diagonal data covariance matrix obtained from residual error analysis accounts for correlated errors. The resulting resistivity models show generally high resistivity values between 3 and 10 Ωm on average which can be partly attributed to depleted pore water salinities due to sea-level low stands in the past, and locally up to 30 Ωm which is likely caused by gas hydrates. At the base of the gas hydrate stability zone resistivities rise up to more than 100 Ωm which could be due to gas hydrate as well as a layer of free gas underneath. However, the deeper parts also show the largest model parameter uncertainties. Archie's Law is used to derive estimates of the gas hydrate saturation, which vary between 30 and 80% within the anomalous layers considering salinity and porosity profiles from a distant DSDP bore hole.

    Full Text Available Robert Louis Stevenson is well known as a writer of popular Victorian adventures, yet much of his fiction is steeped in the cultural and historical preoccupations of Scotland. Texts such as Kidnapped (1886, The Master of Ballantrae (1889, and Catriona (1893 hinge upon culturally significant events such as the Jacobite Rising of 1745 and the Appin Murder. These works also allude to the Highland Clearances of the eighteenth and nineteenth centuries and the Battle of Culloden with its ensuing disarming acts—all occurrences which contributed to or comprised significant catalysts for the large-scale expulsion of Scots from their homeland. Certainly, themes of exile pervade Stevenson’s Scottish work and maintain a more liminal presence in his later South Seas fiction, and many of the author’s finest characters can be read as enactments of temporary or permanent expatriates whose real-life counterparts form a fascinating cross-section of the diasporic movement. This paper focuses on several of these characters, whose adventures are encoded into their corresponding texts as fictional re-constructions of a broader experience common to displaced Scots in the eighteenth and nineteenth centuries. Some are driven from Scotland as a direct result of economic hardship or domestic conflict, while others leave (at least temporarily as a means of avoiding the political corruption and intrigue characteristic of the historical struggle for Scottish independence. Through characters like David Balfour, Alan Breck Stewart, James Durie, and Archie Weir, Stevenson explores the psychological ramifications of politically enforced and self-imposed exile, thus providing fictional extrapolations of the Scottish diasporic experience. These portrayals, infused with a the author’s own experiences abroad, offer fascinating microcosms which gesture towards the collective experience of a wide-scale network of displaced Scots in the Victorian world.

    Bilateral lesions made in the midbrain reticular formation of the rat produced behavioral akinesia. These animals neither ate nor drank. EEGs of these animals usually showed high voltage slow waves at rest. Slight EEG arousal response was demonstrated by clapping, touching and pinching only in rats with moderate impairment. Concerning the rates of local cerebral glucose utilization (LCGU) measured by means of the autoradiographic (/sup 14/C) deoxyglucose method, 13 structures exhibited significant reductions in 28 gray structures examined when compared with sham operated rats. Lesions in the midbrain reticular formation resulted in reduction of LCGU in the neocortex, ventral nucleus of the thalamus, subthalamic nucleus, and medial and lateral geniculated bodies, mamillary body, septal nucleus and caudateputamen. Structures which did not show any significant change in LCGU were those related to the paleo and archi-cortices. These findings suggest the existence of two types of ascending activating systems. Administration of 30 mg/kg of pentobarbital reduced LCGU diffusely throughout the brain. When thyrotropin releasing hormone (TRH) was administered to rats with lesions in the midbrain reticular formation, reversal of the reduction of LCGU was observed in the dorsomedial nucleus of the thalamus and the mamillary body. Reversal of LCGU in the dorsomedial nucleus of thalamus was especially significant and its level exceeded the level of the sham control value. This suggests TRH might exert its function through the dorsomedial nucleus of the thalamus and mamillary body. When TRH was administered to rats treated with pentobarbital, significant reversal was observed in the following structures: the lateral and ventral nucleus of the thalamus, dentate gyrus, caudate-putamen, nucleus accumbens, pontine gray matter, and raphe nucleus.

  19. 'Changes in Tone, Setting, and Publisher: Indigenous Literatures of Australia and New Zealand from the 1980s to Today'

    Full Text Available This article examines four novels written since 1980 by two Aboriginal Australian authors and two Maori authors. Two of the four novels were written near the beginning of this period and feature settings that are contemporary with their publication; The Day of the Dog by Aboriginal Australian author Archie Weller was published in 1981, while Once Were Warriors by Maori author Alan Duff was published in 1990. The other two novels (That Deadman Dance by Aboriginal Australian author Kim Scott and The Trowenna Sea by Maori author Witi Ihimaera are works of historical fiction written in the last decade. The shift in tone between the earlier novels and the more recent novels is particularly remarkable. Coupled with the shift in tone, the settings have changed. It is tempting to ascribe the shifts in tone and setting over this 30-year period to the changing social and political realities surrounding the issue of indigenous relations in the two nations. And these factors undoubtedly played an important role in the aforementioned shifts; indigenous authors writing today are responding to a different social and political reality compared to indigenous authors writing in the 1980s and early 1990s. What this explanation overlooks, however, are the concurrent changes in the publication of indigenous literature and how these might contribute to the types of changes noted above. Indigenous writers are now writing for an international literary marketplace. This article makes it clear that there are significant implications to the shift from indigenous literature being published by small to medium-sized local publishing houses, to indigenous literature being published by the local arm of a multinational conglomerate.

    The arctic is expected to play an important role in the Earth’s future climate due to the large carbon stocks that are stored in permafrost and peatlands, a substantial proportion of which may be released to the atmosphere due to permafrost thawing. There may be positive feedbacks of permafrost thawing on plant growth by releasing stored nitrogen and increasing rooting depth; however, vegetation response to other changing variables such as CO2 and temperature can also modify soil hydrology and energy fluxes, leading to either positive or negative feedbacks on permafrost thawing. Disentangling the interactions between permafrost thawing and vegetation growth is critical for assessing the potential role of arctic regions on current and future global carbon cycling. We have developed a mechanistic, regional, and spatially explicit dynamic ecosystem process model through the integration of a 3-D soil hydrology and biogeochemistry model (Arctic Hydrology, ARCHY) and a dynamic vegetation model (Ecosystem Demography, ED), to quantify the importance of plant-permafrost interactions to soil and plant carbon storage. This model integrates important processes including photosynthesis, transpiration, respiration, 3-D competition for light, 3-D soil hydrology, energy fluxes (ice melting in the soil and solar radiation interception by canopy), nitrogen cycles (microbial decomposition, nitrogen transportation in soil, passive and active nitrogen uptake by plants), species migration, and drought-related mortality. A sensitivity analysis has been implemented to assess the importance of the hydrological cycle, the nitrogen cycle and energy fluxes in regulating the above and below-ground carbon cycles in arctic regions. Our model can fill an important gap between field and global land surface models for assessing plot and regional level hypotheses in the context of global climate.

  1. PIMS: Memristor-Based Processing-in-Memory-and-Storage.

    Energy Technology Data Exchange (ETDEWEB)

    Continued progress in computing has augmented the quest for higher performance with a new quest for higher energy efficiency. This has led to the re-emergence of Processing-In-Memory (PIM) ar- chitectures that offer higher density and performance with some boost in energy efficiency. Past PIM work either integrated a standard CPU with a conventional DRAM to improve the CPU- memory link, or used a bit-level processor with Single Instruction Multiple Data (SIMD) control, but neither matched the energy consumption of the memory to the computation. We originally proposed to develop a new architecture derived from PIM that more effectively addressed energy efficiency for high performance scientific, data analytics, and neuromorphic applications. We also originally planned to implement a von Neumann architecture with arithmetic/logic units (ALUs) that matched the power consumption of an advanced storage array to maximize energy efficiency. Implementing this architecture in storage was our original idea, since by augmenting storage (in- stead of memory), the system could address both in-memory computation and applications that accessed larger data sets directly from storage, hence Processing-in-Memory-and-Storage (PIMS). However, as our research matured, we discovered several things that changed our original direc- tion, the most important being that a PIM that implements a standard von Neumann-type archi- tecture results in significant energy efficiency improvement, but only about a O(10) performance improvement. In addition to this, the emergence of new memory technologies moved us to propos- ing a non-von Neumann architecture, called Superstrider, implemented not in storage, but in a new DRAM technology called High Bandwidth Memory (HBM). HBM is a stacked DRAM tech- nology that includes a logic layer where an architecture such as Superstrider could potentially be implemented.

    The modeling of unsaturated groundwater flow is affected by a high degree of uncertainty related to both measurement and model errors. Geophysical methods such as Electrical Resistivity Tomography (ERT) can provide useful indirect information on the hydrological processes occurring in the vadose zone. In this paper, we propose and test an iterated particle filter method to solve the coupled hydrogeophysical inverse problem. We focus on an infiltration test monitored by time-lapse ERT and modeled using Richards equation. The goal is to identify hydrological model parameters from ERT electrical potential measurements. Traditional uncoupled inversion relies on the solution of two sequential inverse problems, the first one applied to the ERT measurements, the second one to Richards equation. This approach does not ensure an accurate quantitative description of the physical state, typically violating mass balance. To avoid one of these two inversions and incorporate in the process more physical simulation constraints, we cast the problem within the framework of a SIR (Sequential Importance Resampling) data assimilation approach that uses a Richards equation solver to model the hydrological dynamics and a forward ERT simulator combined with Archie's law to serve as measurement model. ERT observations are then used to update the state of the system as well as to estimate the model parameters and their posterior distribution. The limitations of the traditional sequential Bayesian approach are investigated and an innovative iterative approach is proposed to estimate the model parameters with high accuracy. The numerical properties of the developed algorithm are verified on both homogeneous and heterogeneous synthetic test cases based on a real-world field experiment

    This Safety Analysis and Risk Assessment Handbook (SARAH) provides guidance to the safety analyst at the Rocky Flats Environmental Technology Site (RFETS) in the preparation of safety analyses and risk assessments. Although the older guidance (the Rocky Flats Risk Assessment Guide) continues to be used for updating the Final Safety Analysis Reports developed in the mid-1980s, this new guidance is used with all new authorization basis documents. With the mission change at RFETS came the need to establish new authorization basis documents for its facilities, whose functions had changed. The methodology and databases for performing the evaluations that support the new authorization basis documents had to be standardized, to avoid the use of different approaches and/or databases for similar accidents in different facilities. This handbook presents this new standardized approach. The handbook begins with a discussion of the requirements of the different types of authorization basis documents and how to choose the one appropriate for the facility to be evaluated. It then walks the analyst through the process of identifying all the potential hazards in the facility, classifying them, and choosing the ones that need to be analyzed further. It then discusses the methods for evaluating accident initiation and progression and covers the basic steps in a safety analysis, including consequence and frequency binning and risk ranking. The handbook lays out standardized approaches for determining the source terms of the various accidents (including airborne release fractions, leakpath factors, etc.), the atmospheric dispersion factors appropriate for Rocky Flats, and the methods for radiological and chemical consequence assessments. The radiological assessments use a radiological open-quotes templateclose quotes, a spreadsheet that incorporates the standard values of parameters, whereas the chemical assessments use the standard codes ARCHIE and ALOHA

    The gravimetric water content of the waste material is a key parameter in waste biodegradation. Previous studies suggest a correlation between changes in water content and modification of electrical resistivity. This study, based on field work in Mont-Saint-Guibert landfill (Belgium), aimed, on one hand, at characterizing the relationship between gravimetric water content and electrical resistivity and on the other hand, at assessing geoelectrical methods as tools to characterize the gravimetric water distribution in a landfill. Using excavated waste samples obtained after drilling, we investigated the influences of the temperature, the liquid phase conductivity, the compaction and the water content on the electrical resistivity. Our results demonstrate that Archie's law and Campbell's law accurately describe these relationships in municipal solid waste (MSW). Next, we conducted a geophysical survey in situ using two techniques: borehole electromagnetics (EM) and electrical resistivity tomography (ERT). First, in order to validate the use of EM, EM values obtained in situ were compared to electrical resistivity of excavated waste samples from corresponding depths. The petrophysical laws were used to account for the change of environmental parameters (temperature and compaction). A rather good correlation was obtained between direct measurement on waste samples and borehole electromagnetic data. Second, ERT and EM were used to acquire a spatial distribution of the electrical resistivity. Then, using the petrophysical laws, this information was used to estimate the water content distribution. In summary, our results demonstrate that geoelectrical methods represent a pertinent approach to characterize spatial distribution of water content in municipal landfills when properly interpreted using ground truth data. These methods might therefore prove to be valuable tools in waste biodegradation optimization projects. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Weathered/fractured bedrock aquifers contain groundwater resources that are crucial in hard rock basement regions for rural water supply and maintaining river flow and ecosystem resilience. Groundwater storage in metamorphic rocks is subject to high spatial variations due to the large degree of heterogeneity in fracture occurrence and weathering patterns. Point measurements such as borehole testing are, in most cases, insufficient to characterise and quantify those storage variations because borehole sampling density is usually much lower than the scale of heterogeneities. A suite of geophysical and petrographic investigations was implemented in the weathered/fractured micaschist basement of Donegal, NW Ireland. Electrical Resistivity Tomography provided a high resolution 2D distribution of subsurface resistivities. Resistivity variations were transferred into storage properties (i.e. porosities) in the saturated critical zone of the aquifer through application of a petrophysical model derived from Archie's Law. The petrophysical model was calibrated using complementary borehole gamma logging and clay petrographic analysis at multi-depth well clusters distributed along a hillslope transect at the site. The resulting distribution of porosities shows large spatial variations along the studied transect. With depth, porosities rapidly decrease from about a few % in the uppermost, highly weathered basement to less than 0.5% in the deep unweathered basement, which is encountered at depths of between 10 and 50m below the ground surface. Along the hillslope, porosities decrease with distance from the river in the valley floor, ranging between 5% at the river to less than 1% at the top of the hill. Local traces of regional fault zones that intersect the transect are responsible for local increases in porosity in relation to deeper fracturing and weathering. Such degrees of spatial variation in porosity are expected to have a major impact on the modality of the response of

    The IRECCSEM project (www.ireccsem.ie) is a Science Foundation Ireland Investigator Project that is funded to evaluate Ireland's potential for onshore carbon sequestration in saline aquifers by integrating new electromagnetic data with existing geophysical and geological data. The main goals of the project are to determine porosity-permeability values of the potential reservoir formation as well as to evaluate the integrity of the seal formation. During the Summer of 2014 a magnetotelluric (MT) survey was carried out at the Clare basin (Ireland). A total of 140 sites were acquired including audiomagnetotelluric (AMT), broadband magnetotelluric (BBMT) and long period magnetotelluric (LMT) data. The nominal space between sites is 0.6 km for AMT sites, 1.2 km for BBMT sites and 8 km for LMT sites. To evaluate the potential for carbon sequestration of the Clare basin three advances on geophysical methodology related to electromagnetic techniques were applied. First of all, processing of the MT data was improved following the recently published ELICIT methodology. Secondly, during the inversion process, the electrical resistivity distribution of the subsurface was constrained combining three different tensor relationships: Impedances (Z), induction arrows (TIP) and multi-site horizontal magnetic transfer-functions (HMT). Results from synthetic models were used to evaluate the sensitivity and properties of each tensor relationship. Finally, a computer code was developed, which employs a stabilized least squares approach to estimate the cementation exponent in the generalized Archie law formulated by Glover (2010). This allows relating MT-derived electrical resistivity models to porosity distributions. The final aim of this procedure is to generalize the porosity - permeability values measured in the boreholes to regional scales. This methodology will contribute to the evaluation of possible sequestration targets in the study area.

    Carbon capture, sequestration and long-term storage (CCS) is a critically important and intellectually and technologically challenging bridging technology for assisting humanity to migrate from its dependence on fossil fuels to green energy over the next half century. The IRECCSEM project (www.ireccsem.ie) is a Science Foundation Ireland Investigator Project to evaluate Ireland's potential for onshore carbon sequestration in saline aquifers by integrating new electromagnetic geophysical data with existing geophysical and geological data. The main goals of the project are to determine porosity and permeability values of the potential reservoir formation as well as to evaluate the integrity of the seal formation. During the summer of 2014, a magnetotelluric (MT) survey was carried out in the Carboniferous Clare Basin (SW Ireland). Data from a total of 140 sites were acquired, including audio-magnetotelluric (AMT), broadband magnetotelluric (BBMT) and long period magnetotelluric (LMT) data. These new data added to existing MT data acquired at 32 sites during a feasibility pilot survey conducted in 2010. The nominal space between the 2014 sites was 0.6 km between AMT sites, 1.2 km between BBMT sites and 8 km between LMT sites. The electrical resistivity distribution beneath the survey area was constrained using three different types of electromagnetic data: MT impedance tensor responses (Z), geomagnetic transfer functions (GTF) and inter-station horizontal magnetic transfer-functions (HMT). A newly-computed code based on the Generalized Archie's Law and available data from boreholes were used to relate the obtained geoelectrical model to rock properties (i.e. porosity and permeability). The results are compared to independent geological and geophysical data for superior interpretation.

  9. A new method for calculating gas saturation of low-resistivity shale gas reservoirs

    Full Text Available The Jiaoshiba shale gas field is located in the Fuling area of the Sichuan Basin, with the Upper Ordovician Wufeng–Lower Silurian Longmaxi Fm as the pay zone. At the bottom of the pay zone, a high-quality shale gas reservoir about 20 m thick is generally developed with high organic contents and gas abundance, but its resistivity is relatively low. Accordingly, the gas saturation calculated by formulas (e.g. Archie using electric logging data is often much lower than the experiment-derived value. In this paper, a new method was presented for calculating gas saturation more accurately based on non-electric logging data. Firstly, the causes for the low resistivity of shale gas reservoirs in this area were analyzed. Then, the limitation of traditional methods for calculating gas saturation based on electric logging data was diagnosed, and the feasibility of the neutron–density porosity overlay method was illustrated. According to the response characteristics of neutron, density and other porosity logging in shale gas reservoirs, a model for calculating gas saturation of shale gas was established by core experimental calibration based on the density logging value, the density porosity and the difference between density porosity and neutron porosity, by means of multiple methods (e.g. the dual-porosity overlay method by optimizing the best overlay coefficient. This new method avoids the effect of low resistivity, and thus can provide normal calculated gas saturation of high-quality shale gas reservoirs. It works well in practical application. This new method provides a technical support for the calculation of shale gas reserves in this area.

    Besides floodplains, hillslopes are basic units that mainly control water movement and flow pathways within catchments of subdued mountain ranges. The structure of their shallow subsurface affects water balance, e.g. infiltration, retention, and runoff. Nevertheless, there is still a gap in the knowledge of the hydrological dynamics on hillslopes, notably due to the lack of generalization and transferability. This study presents a robust multi-method framework of electrical resistivity tomography (ERT) in addition to hydrometric point measurements, transferring hydrometric data into higher spatial scales to obtain additional patterns of distribution and dynamics of soil moisture on a hillslope. A geoelectrical monitoring in a small catchment in the eastern Ore Mountains was carried out at weekly intervals from May to December 2008 to image seasonal moisture dynamics on the hillslope scale. To link water content and electrical resistivity, the parameters of Archie's law were determined using different core samples. To optimize inversion parameters and methods, the derived spatial and temporal water content distribution was compared to tensiometer data. The results from ERT measurements show a strong correlation with the hydrometric data. The response is congruent to the soil tension data. Water content calculated from the ERT profile shows similar variations as that of water content from soil moisture sensors. Consequently, soil moisture dynamics on the hillslope scale may be determined not only by expensive invasive punctual hydrometric measurements, but also by minimally invasive time-lapse ERT, provided that pedo-/petrophysical relationships are known. Since ERT integrates larger spatial scales, a combination with hydrometric point measurements improves the understanding of the ongoing hydrological processes and better suits identification of heterogeneities.

    As few boreholes may be available and carrying out pumping tests can be expensive and time consuming, relationships between aquifer characteristics and the electrical parameters of different geoelectric layers exist. Data from 19 vertical electrical soundings (VESs; 13 of these selected for evaluation) was recorded with a Schlumberger electrode configuration in the area around Akwuke, Enugu, Nigeria. The data was interpreted by computer iterative modelling with curve matching for calibration purposes. Geoelectric cross-sections along a number of lines were prepared to ascertain the overall distribution of the resistivity responses of the subsurface lithology. Identified probable shallow aquifer resistivity, thickness and depth values are in the range of 28–527 Ωm, 2.1–22.5 m and 3.1–28.3 m respectively. As our aquifer system consists of fine-grained, clay–silty sand materials, a modification of the Archie equations (Waxman–Smits model) was adopted to determine the true formation factor using the relationship between the apparent formation factor and the pore water resistivity. This representation of the effects of a separate conducting path due to the presence of clay particles in the aquifer materials was used in making reliable estimations of aquifer properties. The average hydraulic conductivity of 8.96 × 10 −4 m s −1 transmissivity ranging between 1.88 × 10 −3 and 2.02 × 10 −3 m 2 s −1 estimated from surface resistivity measurements correlated well with the available field data. Results of the study also showed a direct relationship between aquifer transmissivity and modified transverse resistance (R 2 = 0.85). (paper)

  12. Effective conductivity and permittivity of unsaturated porous materials in the frequency range 1 mHz–1GHz

    A model combining low-frequency complex conductivity and high-frequency permittivity is developed in the frequency range from 1 mHz to 1 GHz. The low-frequency conductivity depends on pore water and surface conductivities. Surface conductivity is controlled by the electrical diffuse layer, the outer component of the electrical double layer coating the surface of the minerals. The frequency dependence of the effective quadrature conductivity shows three domains. Below a critical frequency fp, which depends on the dynamic pore throat size Λ, the quadrature conductivity is frequency dependent. Between fp and a second critical frequency fd, the quadrature conductivity is generally well described by a plateau when clay minerals are present in the material. Clay-free porous materials with a narrow grain size distribution are described by a Cole-Cole model. The characteristic frequency fd controls the transition between double layer polarization and the effect of the high-frequency permittivity of the material. The Maxwell-Wagner polarization is found to be relatively negligible. For a broad range of frequencies below 1 MHz, the effective permittivity exhibits a strong dependence with the cation exchange capacity and the specific surface area. At high frequency, above the critical frequency fd, the effective permittivity reaches a high-frequency asymptotic limit that is controlled by the two Archie's exponents m and n like the low-frequency electrical conductivity. The unified model is compared with various data sets from the literature and is able to explain fairly well a broad number of observations with a very small number of textural and electrochemical parameters. It could be therefore used to interpret induced polarization, induction-based electromagnetic methods, and ground penetrating radar data to characterize the vadose zone. PMID:23576823

    A consistent explanation for mantle geophysical anomalies such as the Lithosphere-Astenosphere Boundary (LAB) relies on the existence of little amount of melt trapped in the solid peridotite. Mathematical models have been used to assess the melt fraction possibly lying at mantle depths, but they have not been experimentally checked at low melt fraction (Lanzarote, Canary Islands, Spain) containing various amount of basaltic (MORB-like composition) melt (0 to 100%) at upper mantle conditions. We used the MAVO 6-ram press (BGI) combined with a Solartron gain phase analyser to acquire the electrical resistance of the sample at pressure of 1.5 GPa and temperature up to 1400°C. The results show the increase of the electrical conductivity with the temperature following an Arrhenius law, and with the melt fraction, but the effect of pressure between 1.5 and 3.0 GPa was found negligible at a melt fraction of 0.5 vol.%. The conductivity of a partially molten aggregate fits the modified Archie's law from 0.5 to 100 vol.%. At melt fractions of 0.25, 0.15 and 0.0 vol.%, the EC value deviates from the trend previously defined, suggesting that the melt is no longer fully interconnected through the sample, also supported by chemical mapping. Our results extend the previous results obtained on mixed system between 1 and 10% of melt. Since the melt appears fully interconnected down to very low melt fraction (0.5 vol.%), we conclude that (i) only 0.5 to 1 vol.% of melt is enough to explain the LAB EC anomaly, lower than previously determined; and (ii) deformation is not mandatory to enhance electrical conductivity of melt-bearing mantle rocks.

    The anisotropy of granular media and its evolution during shearing are important aspects required in developing physics-based constitutive models in Earth sciences. The development of relationships between geoelectrical properties and the deformation of porous media has applications to the monitoring of faulting and landslides. However, such relationships are still poorly understood. In this study, we first investigate the definition of the electrical conductivity anisotropy tensor of granular materials in presence of surface conductivity of the grains. Fabric anisotropy is related to the components of the fabric tensor. We define an electrical anisotropy factor based on the Archie's exponent second-order symmetric tensor m of granular materials. We use numerical simulations to confirm a relationship between the evolution of electrical and fabric anisotropy factors during shearing. To realize the simulations, we build a virtual laboratory in which we can easily perform synthetic experiments. We first simulate drained compressive triaxial tests of loose and dense granular materials (porosity 0.45 and 0.38, respectively) using the discrete element method. Then, the electrical conductivity tensor of a set of deformed synthetic samples is computed using the finite-difference method. The numerical results show that shear strains are responsible for a measurable anisotropy in the bulk conductivity of granular media. The observed electrical anisotropy response, during shearing, is distinct for dense and loose synthetic samples. Electrical and fabric anisotropy factors exhibit however a unique linear correlation, regardless of the shear strain and the initial state (porosity) of the synthetic samples. The practical implication of this finding confirms the usefulness of the electrical conductivity method in studying the fabric tensor of granular media. This result opens the door in using time-lapse electrical resistivity to study non-intrusively the evolution of anisotropy

    In Antarctica, ice crystals (platelets) form and grow in supercooled waters below ice shelves. These platelets rise and accumulate beneath nearby sea ice to form a several meter thick sub-ice platelet layer. This special ice type is a unique habitat, influences sea-ice mass and energy balance, and its volume can be interpreted as an indicator for ice - ocean interactions. Although progress has been made in determining and understanding its spatio-temporal variability based on point measurements, an investigation of this phenomenon on a larger scale remains a challenge due to logistical constraints and a lack of suitable methodology. In the present study, we applied a lateral constrained Marquardt-Levenberg inversion to a unique multi-frequency electromagnetic (EM) induction sounding dataset obtained on the ice-shelf influenced fast-ice regime of Atka Bay, eastern Weddell Sea. We adapted the inversion algorithm to incorporate a sensor specific signal bias, and confirmed the reliability of the algorithm by performing a sensitivity study using synthetic data. We inverted the field data for sea-ice and sub-ice platelet-layer thickness and electrical conductivity, and calculated ice-volume fractions from platelet-layer conductivities using Archie's Law. The thickness results agreed well with drill-hole validation datasets within the uncertainty range, and the ice-volume fraction also yielded plausible results. Our findings imply that multi-frequency EM induction sounding is a suitable approach to efficiently map sea-ice and platelet-layer properties. However, we emphasize that the successful application of this technique requires a break with traditional EM sensor calibration strategies due to the need of absolute calibration with respect to a physical forward model.

  17. Scratch's Third Body: Video Talks Back to Television

    2015-12-01

    Full Text Available Emerging in the UK in the 1980s, Scratch Video established a paradoxical union of mass-media critique, Left-wing politics, and music-video and advertising aesthetics with its use of moving-image appropriation in the medium of videotape. Enabled by innovative professional and consumer video technologies, artists like George Barber, The Gorilla Tapes, and Sandra Goldbacher and Kim Flitcroft deployed a style characterized by the rapid sampling and manipulation of dissociated images drawn from broadcast television. Inspired by the cut-up methods of William Burroughs and the audio sampling practiced by contemporary black American musicians, these artists developed strategies for intervening in the audiovisual archive of television and disseminating its images in new contexts: in galleries and nightclubs, and on home video. Reconceptualizing video's “body,” Scratch's appropriation of televisual images of the human form imagined a new hybrid image of the post-industrial body, a “third body” representing a new convergence of human and machine.

    Carlo Alberto Pagni, born in La Spezia, Italy, on February 13, 1931, was an eminent and respected professor of neurosurgery and chairman of the neurosurgical clinic of the University of Turin from 1980 to 2003. He died on March 1, 2009. As a professor of neurology and neurological surgery he was renowned as an expert on vascular, tumor, and functional neurosurgery. Beyond the Italian Neurosurgical Society, he was the doyen of functional neurosurgery, specializing in motor cortex stimulation for the treatment of focal dystonia, Parkinson's disease, and postictal spasticity and pain. His home was his castle, and his family was fundamental to his life. He shared with his wife, Sandra, his passion for piano playing and for their remarkable library, and together with friends, he and his wife enjoyed dinners with fine food and Barolo wines. Listening to this Grand Seigneur talking about and explaining the music of, above all, Ludwig van Beethoven, and Richard Wagner, one felt he was emotionally just "music and mind". You can imagine this from his books on music, chess, and neuroscience. Indeed, he adored playing correspondence chess worldwide. A sportsman too, he loved hiking, mountaineering, skiing, swimming, and fishing. Nature was his source for slowing down, for regenerating, and for collecting his strength for new projects and new challenges. Friends will remember Dr. Pagni as a Grand Seigneur.

    While directing the Future of Nursing: Campaign for Action, Susan B. Hassmiller, the Robert Wood Johnson Foundation's senior adviser for nursing, realized the value that nursing history could bring to the campaign. She decided to interview her mother, Jacqueline J. Wouwenberg, a 1947 graduate of the Bellevue Hospital School of Nursing, in order to better understand and contextualize changes that had occurred in the nursing profession during the 20th century. In collaboration with nurse historians Cathryne A. Welch and Sandra B. Lewenson, Hassmiller participated in interviewing her mother and was also interviewed herself. The stories that emerged revealed a great deal: each woman had found that nursing had given them countless opportunities that reflected the time periods in which they lived. Wouwenberg's experiences, transmitted to Hassmiller through words and actions, also served as important lessons for her daughter. This article shares five lessons: be independent and courageous, know that nursing has no bounds, follow your passion, honor diversity, and give back. It also asks readers to reflect on the relevance of nurses' work from one generation to the next..

    Full Text Available This article employs insights from contemporary theories of ethical reading to conduct a case study of feminist critics’ reaction to the queerness of modernist women’s writing. My aim is to develop a set of practices and principles for ethically responding to queerness in literary texts and everyday life, as well as contribute feminist acumen to the current claim that the humanities are the best site to train students how to do justice to texts. The introduction utilizes theories of ethical reading set forth by Jane Gallop and Eve Kosofsky Sedgwick to develop a preliminary framework of ethical response. The subsequent section provides a historical overview of feminist critics’ reaction to the queerness of modernist women’s literature. I then take my preliminary framework “into the field” to see what it can tell us about how Marianne DeKoven and Sandra Gilbert and Susan Gubar react toward one type of queerness: Gertrude Stein’s experimental language. In my conclusion, I employ the knowledge gained from this analysis along with my theoretical framework to offer feminist insights to the contemporary claim that the humanities are the optimal location to teach ethical reading.

  5. “To Sing with the Spirit:” Psalms, Hymns and the Spirituality of Late Eighteen Century American Presbyterians

    2013-12-01

    Full Text Available This paper contends that the contemporary discussion among theologians regarding the relationship between theology and spirituality can offer new insight into the eighteenth century religious world. This theological discussion has wrestled with, among other things, the questions of whether theology and spirituality are mutually exclusive and what exactly their relationship looks like. Resoundingly, theologians such as Alister McGrath, J. I. Packer, and Sandra Schneiders have concluded that any separation of the two represents a false dichotomy within Christianity. Accordingly, Christians are called to “the quest for a fulfilled and authentic Christian existence, involving the bringing together of the fundamental ideas of Christianity and the whole experience of living on the basis of, and within, the scope of the Christian faith.” Sound theology, then, necessitates living by the Spirit and vice versa. The benefit of this theological position for religious history lies in its reevaluation of the common categorization of Christians as either theologically or spiritually focused. By heeding the call of contemporary theologians and blurring these lines of distinction, historians can afford eighteen century American Christians the chance to better define themselves. Considered in this light, the actions of the Presbyterians, for instance, are freed from the manipulative “social control” framework as one of the “establishmentarian” churches. Instead, the Presbyterians reveal characteristics generally reserved for the democratically charged “sectarians,” such as a robust spiritual life compelled by music.

    2010-01-01

    This address is an exploration of a lifetime of disparate and often conflicting observations about how different people view what is right and good for agriculture, food, and farmers around the world. The exploration utilizes the concept of wicked problems to focus on the issue of differing historical interpretations of global agricultural development. Sandra Batie defines wicked problems as "dynamically complex, ill-structured, public problems" for which "there can be radically different views and understanding of the problem by different stakeholders, with no unique 'correct' view." The wicked problem construct is applied to four core ideas in the history of agricultural development -- small farms, cash crops, agrarian ideals, and international development -- to demonstrate the potential for using this concept to approach complex problems of historical interpretation and contribute to solutions to the challenges of global agricultural development. The author suggests historians should acknowledge contradictory interpretations adn work toward reconciliation and synthesis, where it is possible and, where not, toward a clear explication of the basis for remaining differences. The author also encourages historians to seek multidisciplinary research opportunities that will help bring insights about historical context to policy deliberations.

    The global HIV response has entered a new phase with the recommendation of treating all persons living with HIV with antiretroviral therapy, and with the goals of reducing new infections and AIDS-related deaths to fewer than 500,000 by 2020. This new phase has intensive data requirements that will need to utilize routine data collected through service delivery platforms to monitor progress toward these goals. With a focus on sub-Saharan African, we present the following priorities to improve the demand, supply, and use of routine HIV data: (1) strengthening patient-level HIV data systems that support continuity of clinical care and document sentinel events; (2) leveraging data from HIV testing programs; (3) using targeting data collection in communities and among clients; and (4) building capacity and promoting a culture of HIV data quality assessment and use. When fully leveraged, routine data can efficiently provide timely information at a local level to inform action, as well as provide information at scale with wide geographic coverage to strengthen estimation efforts. ©Brian Rice, Andrew Boulle, Stefan Baral, Matthias Egger, Paul Mee, Elizabeth Fearon, Georges Reniers, Jim Todd, Sandra Schwarcz, Sharon Weir, George Rutherford, James Hargreaves.

Dental erosion is a multifactorial condition that may be idiopathic or caused by a known acid source. Some bleaching agents have a pH lower than the critical level, which can cause changes in the enamel mineral content. Investigations have shown that at-home tooth bleaching with low concentrations of hydrogen or carbamide peroxide have no significant damaging effects on enamel and dentin surface properties. Most studies where erosion was observed were in vitro. Even though the treatment may cause side effects like sensitivity and gingival irritation, these usually disappear at the end of treatment. Considering the literature reviewed, we conclude that tooth bleaching agents based on hydrogen or carbamide peroxide have no clinically significant influence on enamel/dentin mineral loss caused by erosion or abrasion. Furthermore, the treatment is tolerable and safe, and any adverse effects can be easily reversed and controlled.Keywords: peroxide, tooth bleaching, enamel, dentin, erosion, abrasion

    Full Text Available Gillian C Pet, Sandra E Juul Department of Pediatrics, Division of Neonatology, University of Washington, Seattle, WA, USA Abstract: Perinatal asphyxia is a cause of significant neonatal morbidity worldwide. Lack of oxygenation and perfusion to the neonatal brain leads to energy failure and cell death. Currently, therapeutic hypothermia is the standard of care for term infants with hypoxic-ischemic encephalopathy, but as it has shown only modest effects on survival and morbidity, additional neuroprotective agents are needed. Erythropoietin has been extensively studied as a neuroprotective agent for infants who suffer a hypoxic-ischemic brain injury. It has multiple mechanisms of action, in both preventing cell death and promoting tissue repair. Studies have progressed over time from in vitro to in vivo studies, first in animals and now in humans, with several Phase I/II trials completed and Phase III trials underway. As therapeutic hypothermia has become the standard of care in treating term infants with hypoxic-ischemic encephalopathy, studies must now evaluate other neuroprotective agents, including erythropoietin, used in concert with therapeutic hypothermia. Erythropoietin has shown promise as a neuroprotective agent in animal and human models, both alone and together with hypothermia. Keywords: neonate, brain injury

    This paper presents an evaluation of the multi-model simulations for the 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) in terms of their ability to simulate the ERA40 circulation types over the Euro-Atlantic region in winter season. Two classification schemes, k-means and SANDRA, have been considered to test the sensitivity of the evaluation results to the classification procedure. The assessment allows establishing different rankings attending spatial and temporal features of the circulation types. Regarding temporal characteristics, in general, all AR4 models tend to underestimate the frequency of occurrence. The best model simulating spatial characteristics is the UKMO-HadGEM1 whereas CCSM3, UKMO-HadGEM1 and CGCM3.1(T63) are the best simulating the temporal features, for both classification schemes. This result agrees with the AR4 models ranking obtained when having analysed the ability of the same AR4 models to simulate Euro-Atlantic variability modes. This study has proved the utility of applying such a synoptic climatology approach as a diagnostic tool for models' assessment. The ability of the models to properly reproduce the position of ridges and troughs and the frequency of synoptic patterns, will therefore improve our confidence in the response of models to future climate changes.

Type 2 DM (T2DM is a major risk factor for cardiovascular disease (CVD. The management of T2DM is multifactorial, taking into account other major modifiable risk factors, like obesity, physical inactivity, smoking, blood pressure, and dyslipidemia. A multidisciplinary team is essential to maximize the care of individuals with DM. DM self-management education and patient-centered care are the cornerstones of management in addition to effective lifestyle strategies and pharmacotherapy with individualization of glycemic goals. Robust evidence supports the effectiveness of this approach when implemented. Individuals with DM and their family members usually share a common lifestyle that, not only predisposes the non-DM members to developing DM but also, increases their collective risk for CVD. In treating DM, involvement of the entire family, not only improves the care of the DM individual but also, helps to prevent the risk of developing DM in the family members.

  19. Prebiotic Synthesis of Autocatalytic Products From Formaldehyde-Derived Sugars as the Carbon and Energy Source

    2003-01-01

    Our research objective is to understand and model the chemical processes on the primitive Earth that generated the first autocatalytic molecules and microstructures involved in the origin of life. Our approach involves: (a) investigation of a model origin-of-life process named the Sugar Model that is based on the reaction of formaldehyde- derived sugars (trioses and tetroses) with ammonia, and (b) elucidation of the constraints imposed on the chemistry of the origin of life by the fixed energies and rates of C,H,O-organic reactions under mild aqueous conditions. Recently, we demonstrated that under mild aqueous conditions the Sugar Model process yields autocatalytic products, and generates organic micropherules (2-20 micron dia.) that exhibit budding, size uniformity, and chain formation. We also discovered that the sugar substrates of the Sugar Model are capable of reducing nitrite to ammonia under mild aqueous conditions. In addition studies done in collaboration with Sandra Pizzarrello (Arizona State University) revealed that chiral amino acids (including meteoritic isovaline) catalyze both the synthesis and specific handedness of chiral sugars. Our systematic survey of the energies and rates of reactions of C,H,O-organic substrates under mild aqueous conditions revealed several general principles (rules) that govern the direction and rate of organic reactions. These reactivity principles constrain the structure of chemical pathways used in the origin of life, and in modern and primitive metabolism.

In the last 10 years outbreaks have appeared in North America, Europe, and Australia in the form of proctitis among men who have sex with men. Three stages of disease have been described. The disease in primary stage may go undetected when only a painless papule, pustule, or ulceration appears. The diagnosis is difficult to establish on clinical grounds alone and frequently relies upon either serologic testing, culture, or more recently, nucleic acid amplification testing of direct specimens. A proper treatment regimen cures the infection and prevents further damage to tissues. Lymphogranuloma venereum causes potentially severe infections with possibly irreversible sequels if adequate treatment is not begun promptly. Early and accurate diagnosis is essential. Doxycycline is the drug of choice. Pregnant and lactating women should be treated with erythromycin or azithromycin. Patient must be followed up during the treatment, until disease signs and symptoms have resolved. Repeated testing for syphilis, hepatitis B and C, and HIV to detect early infection should be performed.Keywords: sexually transmitted disease, Chlamydia trachomatis, early and accurate diagnosis

    Early detection of congenital heart disease is a worldwide problem. This is more critical in developing countries, where shortage of professional specialists and structural health care problems are a constant. E-learning has the potential to improve capacity, by overcoming distance barriers and by its ability to adapt to the reduced time of health professionals. The study aimed to develop an e-learning pediatric cardiology basics course and evaluate its pedagogical impact and user satisfaction. The sample consisted of 62 health professionals, including doctors, nurses, and medical students, from 20 hospitals linked via a telemedicine network in Northeast Brazil. The course was developed using Moodle (Modular Object Oriented Dynamic Learning Environment; Moodle Pty Ltd, Perth, Australia) and contents adapted from a book on this topic. Pedagogical impact evaluation used a pre and posttest approach. User satisfaction was evaluated using Wang's questionnaire. Pedagogical impact results revealed differences in knowledge assessment before and after the course (Z=-4.788; Pe-learning course on Moodle and the evaluation of its impact, confirming that e-learning is a viable tool to improve training in neonatal congenital heart diseases. ©Ana Cristina Oliveira, Sandra Mattos, Miguel Coimbra.

    We present here the life and work of Shmuel Malkin (1934-2017), an accomplished scientist and a gifted musician who touched the lives of many around the world. His early scientific work addressed the dynamics of light harvesting and electron transport in photosynthesis. Later, he used photoacoustic and photothermal methodologies to explore all aspects of photosynthesis. As a musician, Shmuel played the piano often for family and friends but after his formal retirement, he produced a body of original musical compositions, many of which were performed publicly. Throughout his life, Shmuel was a caring and deeply thoughtful man, respected and loved by colleagues, family, and friends. This tribute presents a summary of Shmuel's work as well as remembrances written by his wife, Nava Malkin, their son, Eyal Malkinson, and many of his colleagues: Michael Havaux from France; Sandra and Marcel Jansen from Ireland; David Cahen, Marvin Edelmann, Joop and Onnie de Graaf, Jonathan Gressel, Uri Pick, Yona Siderer, and Elisha Tel-Or from Israel; Ulrich Schreiber from Germany; James Barber and Alison Telfer from the UK; Govindjee, Stephen Herbert and Thomas Sharkey from the USA. Minnie Ho and Iris Malkin of the USA wrote contributions about Shmuel's music.

    Research scientists claim to have documented a six-fold increase in water use in the United States during the last century. It is interesting to note that the population of the United States has hardly doubled during the last century. While this indicates higher living standards, it also emphasizes an urgent need for establishing a strong, sound, sensible and sustainable management program for utilizing the available water supplies efficiently. Dr. Sandra Postel directs the independent Global Water Policy Project, as well as the Center for the Environment at Mount Holyoke College in South Hadley, Massachusetts. Author of the 1998 book, Last Oasis: Facing Water Scarcity, Dr. Postel predicts big water availability problems as populations of so-called "water-stressed" countries jump perhaps six fold over the next 30 years. The United Nations declared the years 2005 - 2015 as the "Water for Life" decade. It is also interesting and important to observe that the Oil - Rich Middle - East suffers from water scarcity to the maximum extent. It is also recognized that almost three-quarters of the globe is covered with water. Regardless, this is salt-water and there is very limited supply of freshwater to meet the needs of exploding global population. In excess of 10,000 desalination plants operate around the world in more than a hundred countries, but such a process is expensive and may seem prohibitive for developing countries with limited resources. Farmers can cut water usage by adopting the method known as drip irrigation which is known to be highly efficient. Drip Irrigation was pioneered by Israel and the Israeli farmers documented their efficiency by reducing the water used for irrigation by more than 30 percent. Unfortunately the rest of the world has failed to follow the lead set by this Great Jewish Nation. Worldwide, hardly 1percent of irrigated land utilizes efficient drip irrigation techniques. The problem lies in the fact that water is considered to be a free

    Water shortage is a problem of supply and demand. Some authors refer to it as Water Scarcity. The author has discussed this in his previous presentation at the 2008 AGU International Conference. Part of it is reproduced here for purposes of clarification. It is important to recognize that water is essential for the survival of all life on earth. Many water-rich states have thought of water conservation as an art that is practiced mainly in the arid states. But one has to recite the famous quote: “You will never miss water till the well runs dry.” Researchers have also concluded that quantity deficiency experienced by groundwater supplies are affecting many communities around the world. Furthermore federal regulations pertaining to the quality of potable or drinking water have become more stringent (Narayanan, 2008). One must observe that water conservation schemes and efficient utilization practices also benefit the environment to a large extent. These water conservation practicies indeed have a short payback period althought it may seem that there is a heavy initial investment is required. Research scientists have studied MARR (Mean Annual River Runoff) pattern over the years and have arrived at some significant conclusions. Vörsömarty and other scientists have indicated that water scarcity exists when the demand to supply ratio exceeds the number 0.4. (Vörsömarty, 2005). Furthermore other researchers claim to have documented a six-fold increase in water use in the United States during the last century. It is interesting to note that the population of the United States has hardly doubled during the last century. This obviously, is indicative of higher living standards. Nevertheless, it also emphasizes an urgent need for establishing a strong, sound, sensible and sustainable management program for utilizing the available water supplies efficiently (Narayanan, 2008).

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

Body composition data from a female reference group (n = 62, mean age 29 years provided cut-off values for defining sarcopenia.Results: Elderly women had higher body mass index (P < 0.001, lower lean mass (P < 0.001, and higher fat mass (P < 0.01 than the young reference group. Only a small proportion (3.2% had absolute sarcopenia (defined by appendicular skeletal muscle mass/height squared whereas 37% had relative sarcopenia class II (defined by percentage skeletal muscle mass. Scores for TUG and WS indicated relatively poor physical function, yet these measures were not associated with muscle mass or indices of sarcopenia. In multivariate analysis, only hip abductor strength predicted both TUG and WS (both P = 0.01.Conclusion: Hip strength is a more important indicator of physical functioning than lean mass. Measurement of hip strength may therefore be a useful screening tool to detect those at risk of functional decline and requirement for additional care. Further longitudinal studies with a range of other strength measures are warranted.Keywords: aged care, body composition, muscle strength, sarcopenia

  11. Cross-species functionality of pararetroviral elements driving ribosome shunting.

    Directory of Open Access Journals (Sweden)

    Mikhail M Pooggin

    Full Text Available BACKGROUND: Cauliflower mosaic virus (CaMV and Rice tungro bacilliform virus (RTBV belong to distinct genera of pararetroviruses infecting dicot and monocot plants, respectively. In both viruses, polycistronic translation of pregenomic (pg RNA is initiated by shunting ribosomes that bypass a large region of the pgRNA leader with several short (sORFs and a stable stem-loop structure. The shunt requires translation of a 5'-proximal sORF terminating near the stem. In CaMV, mutations knocking out this sORF nearly abolish shunting and virus viability. METHODOLOGY/PRINCIPAL FINDINGS: Here we show that two distant regions of the CaMV leader that form a minimal shunt configuration comprising the sORF, a bottom part of the stem, and a shunt landing sequence can be replaced by heterologous sequences that form a structurally similar configuration in RTBV without any dramatic effect on shunt-mediated translation and CaMV infectivity. The CaMV-RTBV chimeric leader sequence was largely stable over five viral passages in turnip plants: a few alterations that did eventually occur in the virus progenies are indicative of fine tuning of the chimeric sequence during adaptation to a new host. CONCLUSIONS/SIGNIFICANCE: Our findings demonstrate cross-species functionality of pararetroviral cis-elements driving ribosome shunting and evolutionary conservation of the shunt mechanism. We are grateful to Matthias Müller and Sandra Pauli for technical assistance. This work was initiated at Friedrich Miescher Institute (Basel, Switzerland.

Affected patients have symptoms including acroparesthesias, angiokeratomas, and hypohidrosis. More serious manifestations include debilitating pain and gastrointestinal symptoms, proteinuria and gradual deterioration of renal function leading to end-stage renal disease, hypertrophic cardiomyopathy, and stroke. Heterozygous females may have symptoms as severe as males with the classic phenotype. Before 2001, treatment of patients with FD was supportive. The successful development of enzyme replacement therapy (ERT has been a great advancement in the treatment of patients with FD and can stabilize renal function and cardiac size, as well as improve pain and quality of life of patients with FD. In this review, we have provided a critical appraisal of the literature on the effects of ERT for FD. This analysis shows that data available on the treatment of FD are often derived from studies which are not controlled, rely on surrogate markers, and are of insufficient power to detect differences on hard clinical endpoints. Further studies of higher quality are needed to answer the questions that remain concerning the efficacy of ERT for FD.Keywords: Fabry disease, agalsidase α, agalsidase β, Replagal, Fabrazyme, critical appraisal, evidence-based medicine

The goal of this study was to compare outcomes and postoperative complication rates of valved vs nonvalved cannula small-gauge PPV for repair of retinal detachments (RDs complicated by Grade C proliferative vitreoretinopathy (PVR.Methods: A retrospective chart review of 364 consecutive eyes with either valved or nonvalved cannula PPV for RD repair was performed. The primary outcomes were single surgery and final anatomic success and change in best-corrected visual acuity for repair of RDs complicated by Grade C PVR.Results: We identified 36 eyes in the valved group and 31 eyes in the nonvalved group with Grade C PVR RD. The single surgery success was 83% vs 77% (P=0.555 and the final anatomic success was 94% vs 87% (P=0.404 in the valved vs nonvalved eyes, respectively. The mean final visual acuity gain was −0.36 logarithm of the minimum angle of resolution (logMAR; approximate Early Treatment Diabetes Retinopathy Study [ETDRS] score =17 letters in valved eyes vs −0.33 logMAR (approximate ETDRS score =16 letters in nonvalved eyes (P=0.81. Postoperative complication rates including postoperative day 1 hypotony, hypertony, and anterior chamber fibrin formation; postoperative retention of intraocular or subretinal perfluorocarbon liquid; and subsequent epiretinal membrane peel were not statistically different between groups.Conclusion: Valved cannula PPV yields equivalent visual acuity and anatomic outcomes without increased postoperative complication rates compared to traditional nonvalved cannula PPV for Grade C PVR-associated RD repair.

    Full Text Available Sandra J LewisNorthwest Cardiovascular Institute, Portland, OR, USAAbstract: Cardiovascular disease (CVD is the leading cause of death in the US. Despite the decline in CVD-associated mortality rates in recent years, coronary heart disease (CHD still causes one in every six deaths in this country. Because most CHD risk factors are modifiable (eg, smoking, hypertension, obesity, onset of type 2 diabetes, and dyslipidemia, cardiovascular risk can be reduced by timely and appropriate interventions, such as smoking cessation, diet and lifestyle changes, and lipid-modifying therapy. Dyslipidemia, manifested by elevated low-density lipoprotein cholesterol (LDL-C, is central to the development and progression of atherosclerosis, which can be silent for decades before triggering a first major cardiovascular event. Consequently, dyslipidemia has become a primary target of intervention in strategies for the prevention of cardiovascular events. The guidelines of the Adult Treatment Panel (ATP III, updated in 2004, recommend therapeutic lifestyle changes and the use of lipid-lowering medications, such as statins, to achieve specific LDL-C goals based on a person’s global cardiovascular risk. For high-risk individuals, such as patients with CHD and diabetic patients without CHD, an LDL-C target of < 100 mg/dL is recommended, and statin therapy should be considered to help patients achieve this goal. If correctly dosed in appropriate patients, currently approved statins are generally safe and provide significant cardiovascular benefits in diverse populations, including women, the elderly, and patients with diabetes. A recent primary prevention trial also showed that statins benefit individuals traditionally not considered at high risk of CHD, such as those with no hyperlipidemia but elevated C-reactive protein. Additional evidence suggests that statins may halt or slow atherosclerotic disease progression. Recent evidence confirms the pivotal role of

The marker most extensively associated with breast cancer is MUC1. The objective of the study was to analyze prognostic and risk factors in relation to tumor markers in order to clarify breast cancer biology. A total of 349 primary tumor samples and lymph nodes from breast cancer patients were studied. Risk and prognostic factors were considered. An immunohistochemical approach was applied and an extensive statistical analysis was performed, including frequency analysis and analysis of variance. Correlation among variables was performed with principal component analysis.Results: All the antigens showed an increased expression according to tumor size increment; moreover, sialyl Lewis x expression showed a significant increase in relation to disease stage, whereas Tn and TF presented a positive tendency. Vascular invasion was related to sialyl Lewis x expression and number of metastatic lymph nodes. Taking into account risk factors, when a patient had at least one child, Lewis antigens diminished their expression. In relation to breastfeeding, sialyl Lewis x expression diminished, although its apical expression increased.Conclusion: Associations between MUC1 and carbohydrate antigens and risk and prognostic factors show the complexity of the cellular biological behavior that these antigens modulate in breast cancer.Keywords: breast cancer, Argentine women, risk factors, prognostic factors, antigenic expression

Correlational analyses were performed to evaluate the links between empathy scores and psychopathological measures.Results: Patients scored significantly lower than HC on cognitive empathy (CE, while they did not differ from controls on affective empathy (AE. The deficit in CE was not related to either disease severity nor was it related to associated psychopathology.Conclusion: These results, albeit preliminary, suggest that a dysfunctional pattern of CE capacity may be a stable trait of AN-R that should be taken into account not only for the clinical management, but also in preventive and therapeutic intervention.Keywords: anorexia nervosa-restricting type, cognitive empathy, affective empathy, female adolescents, Interpersonal Reactivity Index

Flutracking monitors both the transmission and severity of ILI across Australia by documenting symptoms (cough, fever, and sore throat), time off work or normal duties, influenza vaccination status, laboratory testing for influenza, and health seeking behavior. Recruitment of Flutrackers commenced via health department and other organizational email systems, and then gradually incorporated social media promotion and invitations from existing Flutrackers to friends to enhance participation. Invitations from existing participants typically contribute to over 1000 new participants each year. The Flutracking survey link was emailed every Monday morning in winter and took less than 10 seconds to complete. To reduce the burden on respondents, we collected only a minimal amount of demographic and weekly data. Additionally, to optimize users' experiences, we maintained a strong focus on "obvious design" and repeated usability testing of naïve and current participants of the survey. In this paper, we share these and other insights on recruitment methods and user experience principles that have enabled Flutracking to become one of the largest online participatory surveillance systems in the world. There is still much that could be enhanced in Flutracking; however, we believe these principles could benefit others developing similar online surveillance systems. ©Craig Dalton, Sandra Carlson, Michelle Butler, Daniel Cassano, Stephen Clarke, John Fejsa, David Durrheim.

Laboratory experiments apparently confirmed their role in the causation of atherosclerosis, but a proof of concept requires the corroboration by clinical trials in human beings. The size of benefit in clinical trials regarding the control of high blood pressure was within the estimations of risk provided by cohort studies. For a reduction of 10 mmHg in systolic blood pressure or 5 mmHg in diastolic blood pressure, the relative risk reduction of coronary heart disease was 22% (95% confidence interval 27%–17% in a meta-analysis of clinical trials, close to the estimation of reduction of 25% (95% confidence interval 23%–27% provided by a meta-analysis of cohort studies. The corresponding values for stroke were 41% (95% confidence interval 33%–48% in clinical trials compared to a cohort risk prediction of 36% (95% confidence interval 34%–38%. This efficacy was shared by all blood pressure-lowering drugs. The same figure has not paradoxically happened with drugs that act over abnormalities of cholesterol and lipoproteins. Only statins, which have other beneficial actions as well, have consistently lowered the incidence of cardiovascular diseases, an efficacy that was not reproduced by older and newer quite potent lipid drugs. The adverse effects of these drugs may nullify their beneficial effects over lipoproteins and abnormalities of lipoproteins may only be surrogate markers of the underlying real risks.Keywords: proof of concept, hypertension, lipoproteins, clinical trials

A bakuchiol, Ginkgo biloba extract, and mannitol (BGM complex has been developed to provide patients with acne with a specific dermocosmetic to be used adjunctively with conventional treatments. Objective: The aim of these studies was to assess the antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its individual compounds as well as its impact on sebum composition. Methods: The antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its compounds was assessed through in vitro, ex vivo, and clinical studies. The clinical benefit of BGM complex formulated in a cream was assessed in subjects prone to acne through sebum composition analysis and photometric assessments. Results: Results from the studies showed that the BGM complex has significant antibacterial, anti-inflammatory, and antioxidative properties. At similar concentrations, bakuchiol has up to twice the antioxidative potential than vitamin E. In subjects, BGM complex regulated the sebum composition in acne patients by increasing the level of sapienic and linolenic acid and reducing the level of oleic acid. The reduced number of porphyrins on the skin surface showed that it is also effective against P. acnes. Conclusion: BGM complex provides a complete adjunctive care in patients with acne by targeting etiopathogenic factors of acne: dysseborrhea, inflammation, and P. acnes proliferation.
