  5. [Carl Gustav Jung's alchemical thinking].

    Science.gov (United States)

    Mirkiewicz, Jakub

    2004-01-01

    Carl Gustav Jung (1875-1961), Swiss psychologist and philosopher of culture used in his concepts many constructs having their source in philosophy of alchemy. These ideas can be found not only in his books on alchemy but also in his psychological works. Among them we should enumerate: the theory of psychological process, the concepts of opposites coexisting in the psyche, the polar structure of notions in his psychological system and the idea of synchronicity. The author of this article examines these main points of Jungian program within the context of its parallelism with paracelsian alchemical philosophy of nature: the process of nature, alchemical dialectics and the universal analogy of micro- and macrocosmos. At the beginning of his work, creating his psychology Jung assumed similar ideas. Later, when he noticed this similarity, alchemy became very helpful in his research of psyche, because thanks to them he conceptualised the successive aspects of polar structure of dynamical psychical reality, which--like his alchemical predecessors--he used to explain basics of the micro- and macro-world.

    Toon, Owen B.; Condon, Estelle P. (Technical Monitor)

    1997-01-01

    Inspired by childhood readings of books by Edgar Rice Burroughs, Carl Sagan's first interest in planetary science focused on Mars and Venus. Typical of much of his career he was skeptical of early views about these planets. Early in this century it was thought that the Martian wave of darkening, a seasonal albedo change on the planet, was biological in origin. He suggested instead that it was due to massive dust storms, as was later shown to be the case. He was the first to recognize that Mars has huge topography gradients across its surface. During the spacecraft era, as ancient river valleys were found on the planet, he directed studies of Mars' ancient climate. He suggested that changes in the planets orbit were involved in climate shifts on Mars, just as they are on Earth. Carl had an early interest in Venus. Contradictory observations led to a controversy about the surface temperature, and Carl was one of the first to recognize that Venus has a massive greenhouse effect at work warming its surface. His work on radiative transfer led to an algorithm that was extensively used by modelers of the Earth's climate and whose derivatives still dominate the calculation of radiative transfer in planetary atmospheres today. Carl inspired a vast number of young scientists through his enthusiasm for new ideas and discoveries, his skeptical approach, and his boundless energy. I had the privilege to work in Carl's laboratory during the peak of the era of Mars' initial exploration. It was an exciting time, and place. Carl made it a wonderful experience.

    1996-01-01

    Eugen Bleuler's letter of recommendation for Carl Gustav Jung's appointment as a lecturer In January 1905, Eugen Bleuler (1857-1939) wrote a letter of recommendation to the Medical Faculty of the University of Zurich, urging them to accept the application of Carl Gustav Jung (1875-1961) as a lecturer there. Bleuler's letter mentions the contribution to Jung's writing made by Franz Riklin (1878-1938), although he does not define it precisely. It is safe to say that, judging from the way in which Bleuler expresses his opinions in this letter, this may be regarded at the very least as an early sign of his receptiveness to the psychoanalytical ideas of the time.

  16. Antigen uptake, processing and presentation to T-cells is still functional in dendritic cells surviving photodynamic treatment

    International Nuclear Information System (INIS)

    Full text: The effect of photodynamic therapy (PDT) on anti-tumoral immune reactions is still discussed controversially. Several studies have demonstrated that PDT is able to activate immune reactions against tumor antigens. However, there is also evidence that PDT exerts immunosuppressive effects. Dendritic cells (DC) are professional antigen presenting cells and play an important role in, both, the induction of immune reactions as well as the induction and maintenance of immunologic tolerance. Therefore, we investigated the effect of hypericin-mediated PDT on the capability of bone marrow-derived DC for antigen uptake, processing and presentation to CD4+ T lymphocytes. Using beta-galactosidase as model antigens we found that, under sublethal PDT conditions, antigen is still incorporated and degraded by surviving DC. PDT-treated DC, in the presence of beta-galactosidase, were still able to re-activate splenic T cells from immunized but not from naive mice. Similarly, naive allogenic T cells were activated in an antigen-independent manner by PDT-treated DC, albeit at lower efficiency as compared to untreated DC. Based on these data, we hypothesize that DC localized in PDT-treated tumor lesions could play a role in the regulation of anti-tumor immune reactions. (author)

  17. Development of an automated processing method to detect still timing of cardiac motion for coronary magnetic resonance angiography

    Whole-heart coronary magnetic resonance angiography (WH-MRA) is useful noninvasive examination. Its signal acquisition is performed during very short still timing in each cardiac motion cycle, and therefore the adequate still timing selection is important to obtain the better image quality. However, since the current available selection method is only manual one using visual comparison of cine MRI images with different phases, the selected timings are often incorrect and their reproducibility is not sufficient. We developed an automated selection method to detect the best still timing for the WH-MRA and compared the automated method with conventional manual one. Cine MRI images were used for the analysis. In order to extract the high-speed cardiac cine image, each phase directional pixel set at each pixel position in all cine images were processed by a high-pass filtering using the Fourie transform. After this process, the cine images with low speed timing became dark, and the optimal timing could be determined by a threshold processing. We took ten volunteers' WH-MRA with the manually and automatically selected timings, and visually assessed image quality of each image on a 5-point scale (1=excellent, 2=very good, 3=good, 4=fair, 5=poor). The mean scores of the manual and automatic methods for right coronary arteries (RCA), LDA left anterior descending arteries (LAD) and LCX left circumflex arteries (LCX) were 4.2+/-0.38, 4.1+/-0.44, 3.9+/-0.52 and 4.1+/-0.42, 4.1+/-0.24, 3.2+/-0.35 respectively. The score were increased by our method in the RCA and LCX, and the LCX was significant (pcardiac phase more accurately than or equally to the conventional manual method.

    2009-06-01

    Full Text Available The paper deals with Carl Schmitt’s theory of democracy, aiming at presenting its merits and deficiencies. The argumentation is divided into two parts. Initially, the thesis that Schmitt’s theory works within two different levels, i.e., a conceptual one, which is essentially analytical, and a phenomenal one, which according to him would be descriptive only, is sustained. At this point, Schmitt’s theory of democracy and its critique of parliamentary democracy can be better understood. Finally, some criticisms against Schmitt’s position are presented.

    Full Text Available Giorgio Agamben’s politics of life intertwines two diverging traditions of philosophical thought: Michel Foucault’s biopolitics and Carl Schmitt’s political philosophy. With the help of Carl Schmitt’s concept of “political romanticism,” I interpret Agamben’s strategy as an attempt to introduce a bio-aesthetics of political vitality. Moreover, I situate Agamben’s politics of life in opposition to Schmitt’s biopolitics.

  5. Carl Størmer Auroral Pioneer

    CERN Document Server

    Egeland, Alv

    2013-01-01

    This biography summarizes the seminal contributions to auroral and space science of Carl Størmer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Størmer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth’s magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Størmer’s crowning achievement, “The Polar Aurora,” published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics.   The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.

  6. Carl Linnaeus and the visual representation of nature.

    Science.gov (United States)

    Charmantier, Isabelle

    2011-01-01

    The Swedish naturalist Carl Linnaeus (1707-1778) is reputed to have transformed botanical practice by shunning the process of illustrating plants and relying on the primacy of literary descriptions of plant specimens. Botanists and historians have long debated Linnaeus's capacities as a draftsman. While some of his detailed sketches of plants and insects reveal a sure hand, his more general drawings of landscapes and people seem ill-executed. The overwhelming consensus, based mostly on his Lapland diary (1732), is that Linnaeus could not draw. Little has been said, however, on the role of drawing and other visual representations in Linnaeus's daily work as seen in his other numerous manuscripts. These manuscripts, held mostly at the Linnean Society of London, are peppered with sketches, maps, tables, and diagrams. Reassessing these manuscripts, along with the printed works that also contain illustrations of plant species, shows that Linnaeus's thinking was profoundly visual and that he routinely used visual representational devices in his various publications. This paper aims to explore the full range of visual representations Linnaeus used through his working life, and to reevaluate the epistemological value of visualization in the making of natural knowledge. By analyzing Linnaeus's use of drawings, maps, tables, and diagrams, I will show that he did not, as has been asserted, reduce the discipline of botany to text, and that his visual thinking played a fundamental role in his construction of new systems of classification.

    Ashley, Paul; Muse, Anthony

    2008-02-01

    A baseline habitat evaluation procedures (HEP) analysis was conducted on the Carl property (160 acres) in June 2007 to determine the number of habitat units to credit Bonneville Power Administration (BPA) for providing funds to acquire the property as partial mitigation for habitat losses associated with construction of McNary Dam. HEP surveys also helped assess the general ecological condition of the property. The Carl property appeared damaged from livestock grazing and exhibited a high percentage of invasive forbs. Exotic grasses, while present, did not comprise a large percentage of the available cover in most areas. Cover types were primarily grassland/shrubsteppe with a limited emergent vegetation component. Baseline HEP surveys generated 356.11 HUs or 2.2 HUs per acre. Habitat units were associated with the following HEP models: California quail (47.69 HUs), western meadowlark (114.78 HUs), mallard (131.93 HUs), Canada goose (60.34 HUs), and mink (1.38 HUs).

  1. Progress in the desulfurization of coke oven gas and utilization of H[sub 2]S - Still Otto's SOLOX process

    1994-01-01

    The SOLOX process developed by Still Otto to remove sulfur from coke oven gas down to a content of less than 2 ppm of H[sub 2]S is essentially based on practical experience gained from the construction of plants operating according to the well-known Stretford process. Economic as well as ecological problems with secondary pollutant formation from H[sub 2]S, HCN and O[sub 2] which are notorious in liquid-phase oxidation processes could be eliminated by providing for a combination with salt cracking processes operating according to the liquid-phase hydrolysis principle, with the gaseous hydrolysis products H[sub 2]S, NH[sub 3] and CO[sub 2] being returned to the raw gas and the regenerated solution recycled to the absorption process. The desulfurization process can either be located downstream of the NH[sub 3] BTX removal unit which is the typical arrangement or, as a modified solution, upstream of it. A cost-benefit analysis has revealed the advantages of the new process over the AS circulation and vacuum-carbonate processes both from an economic as well as ecological view point. 21 refs., 11 figs., 6 tabs.

On the other hand, if you want a detailed, fascinating and exhaustively researched story about a very special person, then read it. The author has produced a painstaking picture of Sagan. The main text consists of 430 pages of stories, anecdotes, quotations etc, which lead us through the complex life of a very complex man. This is backed up with a further 70 pages of detailed references followed by a 19 page bibliography. We learn about Sagan from his early days, when he was a somewhat precocious schoolboy, right up to his final days when he was in poor health yet still turning out books at a great rate. Like many people, I knew of him but not very much about him before I read this book. He was a man of giant energy who attempted to combine the life of a working research scientist with that of a great popularizer as well as extending his tentacles into various aspects of (scientific) government policy. Even in his early days his one aim in life seemed to be that of furthering his own career by getting to know as many well-known scientists as possible. He had fingers in many pies - academic, something mysterious and military related, book writing, popular science on TV etc, etc. He was particularly concerned with the space programme, especially the planetary probes and the Voyager vehicles which took messages from Earth to outer space. We get the impression from the book that he was especially obsessed with extraterrestrial life and was desperate to confirm its existence. He was instrumental in keeping the SETI programme going even though it eventually had to go private. We learn that he was not a good family man and work usually took precedence over domestic issues. As a result his private life seems to have been as complicated as his professional life. He was a man whose mind went in several directions at once and he was

    The common interpretation of Carl Menger’s take on capital theory rests upon a few sentences in his Principles of Economics. His later monograph on the topic, Zur Theorie des Kapitals (A contribution to the theory of capital), is more or less ignored, although it must be seen as a recantation of his earlier views. As it becomes clear in this work, Menger would have opposed all attempts to define capital as a heterogeneous structure of higher-order goods – a definition that is associated with ...

    Full Text Available Carl Menger founded the Austrian School of economics at the end of the 19th century. He rejected some of the main ideas of the German Historical School in his work Investigations into the Method of the Social Sciences with Special Reference to Economics (1881. The submitted paper presents the main implications of the investigations on the theory of economic history with a special reference to the economic history and history of economic thought of the Balkans. The emphasis is on the methodological subjectivism, spontaneous order, rejection of the teleological understanding of the process of economic development, and the application of mathematical models. These principles could be used as a theoretical base of the historical research, though they are widely underestimated in modern economic history.

    2016-08-01

    Granville Stanley Hall (1844-1924) with William James (1842-1910) is the key founder of psychology of religion movement and the first American experimental or genetic psychologist, and Carl Gustav Jung (1875-1961) is the founder of the analytical psychology concerned sympathetically about the religious dimension rooted in the human subject. Their fundamental works are mutually connected. Among other things, both Hall and Jung were deeply interested in how the study of religious experience is indispensable for the depth understanding of human subject. Nevertheless, except for the slight indication, this common interest between them has not yet been examined in academic research paper. So this paper aims to articulate preliminary evidence of affinities focusing on the locus and its function of the inner deep psychic dimension as the religious in the work of Hall and Jung.

    It is argued that there is a significant existential perspective in the thought of Carl Jung. Similarities and differences with some of the views of Jean Paul Sartre are explored as a way of developing this perspective and to show how a philosophy of a man might be developed drawing from both sources. Jung is shown to be in disagreement with Sartre in defending an idea of a determinate human nature, describing the self in a developmental way, and in not claiming that human freedom is absolute or unconditioned. Nevertheless, the Jungian concept of individuation is similar to Sartre's ideal of authenticity, in that both focus on the goal of achieving meaningful existence through development of inner resources, creative exercise of freedom, and overcoming self-deception.

    Full Text Available El presente trabajo desarrolla distintas figuras que Carl Schmitt señala como formas de subjetividad antipolítica. Si desde la perspectiva del jurista alemán las operaciones que constituyen un modo de ser político son aquellas que producen o sostienen una forma representativa, lo propio de una subjetividad antipolítica son aquellas operaciones que erosionan o conducen a la destrucción de dicha forma política. El trabajo intenta mostrar que la operación fundamental en este sentido es la dilación, entendida como la postergación indefinida de la decisión. Así, bajo las diversas figuras de la antipolítica que Schmitt aborda, esta operación también adquiere diversas formas de aparición: en el caso de la subjetividad liberal se da bajo la forma de la discusión y el compromiso, en el caso del romántico político bajo la forma de la poetización.This paper develops various figures noted by Carl Schmitt as forms of anti-political subjectivity. Whereas, from the German jurist's perspective, the operations which constitute a political way of being are those which produce and care for a representative form, the specificity of a anti-political subjectivity is shaped by those operations which erode or wear that political form down. The paper aims to show that the main feature of the antipolitical way of being is the delay, meaning the indefinite postponement of the decision as such. Thus, under the various figures of the anti-politics that Schmitt deals with, this operation appears on different manners: the liberal form of postponing is the endless discussion and the compromise; the romatic form is the aesthetization of the world.

  3. Gulf operations still recovering

    International Nuclear Information System (INIS)

    This paper reports that reports of damage caused by Hurricane Andrew were leveling off last week at the U.S. Minerals Management Service as Gulf of Mexico operators pressed ahead with repairs. The hurricane struck South Florida Aug. 4, churned west into the gulf, then swung north and hit the South Louisiana coast Aug. 5. By the close of business Sept. 8 MMS had received damage reports covering 83 pipeline segments and 193 platforms and satellite installations. MMS last week estimated about 500 MMcfd of gas production had been restored in the gulf and 100,000-150,000 b/d of oil. Production still lost as a result of Andrew was estimated at 2-2.5 bcfd of gas and 90,000-120 b/d of oil. MMS estimates Gulf of Mexico wells before the storm were producing about 12.5-13 bcfd of gas and 750,000 b/d of oil

  4. The Carl Sagan solar and stellar observatories as remote observatories

    Science.gov (United States)

    Saucedo-Morales, J.; Loera-Gonzalez, P.

    In this work we summarize recent efforts made by the University of Sonora, with the goal of expanding the capability for remote operation of the Carl Sagan Solar and Stellar Observatories, as well as the first steps that have been taken in order to achieve autonomous robotic operation in the near future. The solar observatory was established in 2007 on the university campus by our late colleague A. Sánchez-Ibarra. It consists of four solar telescopes mounted on a single equatorial mount. On the other hand, the stellar observatory, which saw the first light on 16 February 2010, is located 21 km away from Hermosillo, Sonora at the site of the School of Agriculture of the University of Sonora. Both observatories can now be remotely controlled, and to some extent are able to operate autonomously. In this paper we discuss how this has been accomplished in terms of the use of software as well as the instruments under control. We also briefly discuss the main scientific and educational objectives, the future plans to improve the control software and to construct an autonomous observatory on a mountain site, as well as the opportunities for collaborations.

    Sanchez-Ibarra, A.

    The current status of Observatory "Carl Sagan" (OCS) of University of Sonora is presented. This project was born in 1996 focused to build a small solar-stellar observatory completely operated by remote control. The observatory will be at "Cerro Azul", a 2480 m peak in one of the best regions in the world for astronomical observation, at the Sonora-Arizona desert. The OCS, with three 16 cm solar telescopes and a 55 cm stellar telescope is one of the cheapest observatories, valuated in US200,000 Added to its scientific goals to study solar coronal holes and Supernovae Type 1A, the OCS has a strong educative and cultural program in Astronomy to all levels. At the end of 2001, we started the Program "Constelacion", to build small planetariums through all the countries with a cost of only US80,000. Also, the webcast system for transmission of the solar observations from the prototype OCS at the campus, was expanded to webcast educational programs in Astronomy since July of this year, including courses and diplomats for Latin American people. All of these advances are exposed here.

The suggestion is that, within the undividedly accepted educational strategy of the West, there are still uninspected costs and smuggled dilemmas. They then burden the contemporary disputes over education at a lower level of generality: general or vocational, culturally determined or universal, standardized or deregulated, uniform or plural, privileged or available to all, elite or “open” education, and so on. We believe that such thorough clearing up of conceptual field would point to those presumed purposes, functions, and outcomes of education which make its investments seem constantly unsatisfactory, and education itself appears chronically in crisis.

    Full Text Available Apresentaremos um esboço de alguns pontos do pensamento do jurista alemão Carl Schmitt, fundamentalmente no período da República de Weimar e parte do regime nazista. Será dada maior atenção à sua relação com o conceito de decisão e como tal conceito permeou seus escritos em torno da crítica ao liberalismo/parlamentarismo de Weimar; atentaremos ainda para sua defesa da existência de um Estado Forte como produto da inevitabilidade existencial, da distinção social entre amigos-inimigos e de uma homogeneidade racial e “democrática”, idéias que serviram de esteio ao regime nazista. Tomamos como base de análise as seguintes obras suas em edições mais recentes: A Ditadura 1921, Teologia Política 1922, A Situação intelectual (espiritual do sistema parlamentar atual 1923 e O Conceito do Político 1927. Objetivamos, com assim, contribuir para uma reflexão mais atenta a respeito de um certo "revisionismo schmitiano” que busca, por todos os meios, apresentá-lo como pensador democrático e minimizar sua ligação com o regime nazista, no período de 1933 a 1936 quando esteve ligado ao partido de Hitler. Com isso, se objetiva alertar para o reavivamento de suas idéias de extrema direita, sobretudo em países como Alemanha, Áustria, Itália e, mais recentemente, nos Estados Unidos. Na reflexão sobre pontos de seu pensamento, nos apoiaremos nos escritos de pensadores como Richard Wolin, Kal Löwith, Nicolas Tertulian, Heinrich Meier, Jean-Luc Evard, Jürgen Habermas e no Brasil, Roberto Romano e Bernardo Ferreira.

    Directory of Open Access Journals (Sweden)

    Jansen Martin

    2011-08-01

    Full Text Available Abstract Background The therapeutic success of chemotherapeutic agents is often limited by severe adverse effects. To reduce toxicity of these drugs, nanoscale particle-based drug delivery systems (DDS are used. DDS accumulate to some extent in tumor tissues, but only a very small portion of a given dose reaches this target. Accumulation of DDS in tumor tissues is supposed to be much faster than in certain other tissues in which side effects occur ("Kinetic Targeting". Once saturation in tumor tissue is achieved, most of the administered DDS still circulate in the plasma. The extracorporeal elimination of these circulating nanoparticles would probably reduce toxicity. Methods For the CARL-trial (Controlled Application and Removal of Liposomal chemotherapeutics, pegylated liposomal doxorubicin (PLD was used as chemotherapeutic agent and double filtration plasmapheresis (DFPP was performed for extracorporeal elimination of liposomes. PLD was given as 40 mg/m2 every 3 weeks in combination with vinorelbine 2 × 25 mg/m2 (neoadjuvant treatment of breast cancer, 12 patients, or as 40 mg/m2 every 4 weeks (recurrent ovarian cancer, 3 patients. Primary endpoints were the efficiency and safety profile of DFPP, and secondary endpoints were side effects and tumor response. Results DFPP eliminated ~62% of circulating PLD, corresponding to ~45% of the total dose (n = 57 cycles. AUC of doxorubicin was reduced by 50%. No leakage of doxorubicin was detected during elimination, and no relevant DFPP-related side effects occurred. Reduction in tumor size > 30% occurred in 10/12 (neoadjuvant and in 1/3 patients (recurrent. Only five grade 2 events and one grade 3 event (mucositis, neutropenia or leucopenia and a single palmar-plantar erythrodysesthesia grade 2 were reported. Conclusion Extracorporeal elimination of PLD by DFPP is safe and efficient. CARL can diminish the main dose-limiting side effects of PLD, and probably many different DDS alike. Trial

    2014-01-01

    What are 'interpretations' of quantum theory? What are the differences between Carl Friedrich von Weizsäkcker's approach and contemporary views? The various interpretations of quantum mechanics give diverse answers to questions concerning the relation between measuring process and standard time development, the embedding of quantum objects in space ('wave-particle-dualism'), and the reference of state vectors. Does the wave function describe states in the real world or does it refer to our knowledge about nature? First, some relevant conceptions in Weizsäcker's book The Structure of Physics (Der Aufbau der Physik, 1985) are introduced. In a second step I point out why his approach is not any longer present in contemporary debates. One reason is that Weizsäcker is mainly affected by classical philosophy (Platon, Aristoteles, Kant). He could not esteem the philosophy of science that was developed in the spirit of logical empiricism. So he lost interest in disputes with Anglo-Saxon philosophy of quantum mechanics. Especially his interpretation of probability and his analysis of the collapse of the state function as change in knowledge differ from contemporary standard views. In recent years, however, epistemic interpretations of quantum mechanics are proposed that share some of Weizsäcker's intuitions. PMID:24974602

    Full Text Available Abstract Background Maps and mapping tools through geographic information systems (GIS are highly valuable for turning data into useful information that can help inform decision-making and knowledge translation (KT activities. However, there are several challenges involved in incorporating GIS applications into the decision-making process. We highlight the challenges and opportunities encountered in implementing a mapping innovation as a KT strategy within the non-profit (public health sector, reflecting on the processes and outcomes related to our KT innovations. Methods A case study design, whereby the case is defined as the data analyst and manager dyad (a two-person team in selected Ontario Early Year Centres (OEYCs, was used. Working with these paired individuals, we provided a series of interventions followed by one-on-one visits to ensure that our interventions were individually tailored to personal and local decision-making needs. Data analysis was conducted through a variety of qualitative assessments, including field notes, interview data, and maps created by participants. Data collection and data analysis have been guided by the Ottawa Model of Research Use (OMRU conceptual framework. Results Despite our efforts to remove all barriers associated with our KT innovation (maps, our results demonstrate that both individual level and systemic barriers pose significant challenges for participants. While we cannot claim a causal association between our project and increased mapping by participants, participants did report a moderate increase in the use of maps in their organization. Specifically, maps were being used in decision-making forums as a way to allocate resources, confirm tacit knowledge about community needs, make financially-sensitive decisions more transparent, evaluate programs, and work with community partners. Conclusions This project highlights the role that maps can play and the importance of communicating the importance of

    (1) Quantum theory deals not just with reality but with the physical (scientific) reality of its objects. Carl Friedrich von Weizsäcker understood this to imply that scientific knowledge of objects converges with philosophical knowledge of their objectivity but did not succeed in rounding off physics. (2) We are actors as well as spectators not only in scientific knowledge but in political processes as well, particularly by means of science. It is, therefore, not justified to deny political responsibility even in 'basic research'. Carl Friedrich von Weizsacker identified classical physics as the venture of knowledge without love but believed that this boundary could be transcended. The apparent neutrality of science must not be tolerated by the churches, however. (3) In religion Weizsäcker felt most at home in Buddhist spirituality, this being akin to Christian spirituality which has been more or less lost by the Christian churches. Yet he tried to support his church and to participate in its actions. (4) Lack of love corresponds to an excess of power in the religious critique of science. In both respects Weizsäcker presented the mirror to industrial society but people in general did not recognize their image. The Max-Planck-Society, however, shut up Weizsäcker's "Institute for the study of the conditions of life in the modern world" (Starnberg 1970-1980) as soon as possible. (5) Weizsäcker always refrained from exerting any power except that of reason or truth. According to Lao Tse this is the power least perceived as such. In politics he generally followed the mainstream after once having been tempted to action in 1941/42. His influence on German society was based on his charismatic spirituality. PMID:24974621

  2. Psyche=singularity: A comparison of Carl Jung's transpersonal psychology and Leonard Susskind's holographic string theory

    Science.gov (United States)

    Desmond, Timothy

    In this dissertation I discern what Carl Jung calls the mandala image of the ultimate archetype of unity underlying and structuring cosmos and psyche by pointing out parallels between his transpersonal psychology and Stanford physicist Leonard Susskind's string theory. Despite his atheistic, materialistically reductionist interpretation of it, I demonstrate how Susskind's string theory of holographic information conservation at the event horizons of black holes, and the cosmic horizon of the universe, corroborates the following four topics about which Jung wrote: (1) his near-death experience of the cosmic horizon after a heart attack in 1944; ( 2) his equation relating psychic energy to mass, "Psyche=highest intensity in the smallest space" (1997, 162), which I translate into the equation, Psyche=Singularity; (3) his theory that the mandala, a circle or sphere with a central point, is the symbolic image of the ultimate archetype of unity through the union of opposites, which structures both cosmos and psyche, and which rises spontaneously from the collective unconscious to compensate a conscious mind torn by irreconcilable demands (1989, 334-335, 396-397); and (4) his theory of synchronicity. I argue that Susskind's inside-out black hole model of our Big Bang universe forms a geometrically perfect mandala: a central Singularity encompassed by a two-dimensional sphere which serves as a universal memory bank. Moreover, in precise fulfillment of Jung's theory, Susskind used that mandala to reconcile the notoriously incommensurable paradigms of general relativity and quantum mechanics, providing in the process a mathematically plausible explanation for Jung's near-death experience of his past, present, and future life simultaneously at the cosmic horizon. Finally, Susskind's theory also provides a plausible cosmological model to explain Jung's theory of synchronicity--meaningful coincidences may be tied together by strings at the cosmic horizon, from which they

    Directory of Open Access Journals (Sweden)

    Maritza Ceicilia Felices Luna

    2013-09-01

    Full Text Available This article postulates that the study of political violence and armed conflict contributes to critical criminological theory by suggesting to look into Carl Schmitt’s concept of ‘the political’ as an alternative to the more typical conceptualisations of ‘politics’ (i.e. Weberian -power-, Marxist -class struggle- or Foucualdian -domination. It is my contention that the latter dilute politics into the economic, social, cultural sphere given that almost everything can be surmise to be an issue of power, domination or class struggle whereas the former highlights the boundaries of the political realm while still allowing for analytical connections and links to be established with the other spheres of society. The concept of ‘the political’ has opened up new avenues for those working on issues of state crimes, mass atrocities and social harm. Moreover, it can reinvigorate critical criminology’s denunciation of the state, its social control apparatuses (such as the criminal justice system as well as other modes of governance by articulating the destructive character of the criminal justice system and of similar forms of social control.

    Full Text Available The Corpus of Levantine Rock Art [CARL] (1971-1976 is a compilation, as yet unmatched in quality, of color photographs and contextual information on three quarters of the paintings known in Mediterranean Spain. Our reconstruction of its genesis is based on published literature, archival records, and oral history (the last of these constituting a particularly important source for the history of science. Its formation by the prehistorian M. Almagro Basch and the photographer F. Gil Carles illustrates the institutional, personal, and economic context of research in the Franco era. We emphasize Almagro’s contributions in studying, documenting and protecting the art and in resorting to an external purveyor within a scientific project. Gil Carles’s training, his work and his innovative classification of the material (described here for the first time made him Spain’s first heritage photographer. The article shows how the combined efforts of the two made the CARL the only systematic Spanish photographic archive built on an interregional scale and with explicit criteria.

    2002-01-01

    Full Text Available The objective of this article is to discuss the link in the work of Carl Schmitt between the critique of romanticism and the reflection on the themes of sovereignty and decision. Based on an analysis of some key issues in the books Politische Romantik (Political Romanticism, Politische Theologie (Political Theology, and Die Diktatur (The Dictatorship, the article analyzes how, in Carl Schmitt, romanticism and decisionism represent counterpoised conceptual universes, which refer to each other in various aspects. The attempt is thus to highlight both the structurally controversial nature of the German jurist?s ideas and the close ties between his legal/political theory and his critique of the liberal-bourgeois order as a synthesis of modernity.

    The paper deals with Carl Friedrich von Weizsäcker's position within the philosophy of mind. It turns out that Weizsäcker's ontology is based on an unorthodox conception both in the philosophy of physics and in the philosophy of mind. His quantum information theoretic reductionism is based on a subtle combination of atomism and holism, his philosophy of mind connected to this is a neutral monism, which proposes a bold intertwining of mind, matter, and space.

The following processes are described: the Vacuum-Carbonate process, the Sulfiban process, the Carl Still process, the Otto-Sulfammon process, the Takahax-Hirohax process, the Holmes-Stretford process and the Fumaks process. Flowsheets of desulfurization systems are shown. Desulfurization efficiency, content of hydrogen sulfide in coal gas after desulfurization, desulfurization cost and regeneration methods are analyzed. The Holmes-Stretford process and the Sulfiban process are characterized by the highest efficiency (hydrogen sulfide content in coal gas leaving desulfurization system is 0.115 g/m/sup 3/ and 0.15-0.16 g/m/sup 3/ respectively).

    The aim of this article is to get closer to the myth of Jung, this is part of the inner experiences that took place in his first childhood, and in which we can already see the foundation of his work and the development of key concepts as: the unconscious, Self, archetype and individuation process. His life is the display of his unconscious and this is what his work is about. We cannot understand Jung without taking into account the fundamental importance that he gives to the inner world: the dreams and fantasies; and the direct contact that he has had with these aspects since he was a little boy.

  10. Evaluation of the flathead catfish population and fishery on Lake Carl Blackwell, Oklahoma, with emphasis on the effects of noodling

    2011-01-01

    I conducted a 3-year study at Lake Carl Blackwell, Oklahoma to estimate effects of various fishing gears on the flathead catfish Pylodictis olivaris population. Managers were particularly interested in the effect of handfishing or noodling on this population. I used a phone survey to assess angler effort and electrofishing and gill nets to calculate standard population metrics to assess composition of the current population. Survey data indicated that fishing effort and harvest were highest for trotlines and juglines and lowest for noodling. Size distribution of fish harvested by noodlers was not different from sizes that were available in the fishery and was similar to those fish harvested with other gears. Flathead catfish Sampled in Lake Carl Blackwell ranged in size from 38 to 1,220 mm total length, and 77% of the population was less than 508 mm (minimum legal size). Estimated total annual mortality was about 11%. Proportional size distribution (PSD) of flathead catfish for Lake Carl Blackwell indicates that about 70% of legal-sized flathead catfish were over the preferred size of 710 mm. Overall, the Lake Carl Blackwell flathead catfish population appeared healthy. There were a wide range of sizes and ages in the population, and PSD indicated a well-balanced population with many preferred and memorable-sized fish. Due to its rarity, noodling is probably not adversely influencing the population. Additionally, noodling at Lake Carl Blackwell does not appear to be as size-selective as previously thought.

    2013-12-01

    We describe similarities in the ontology of quantum physics and of Carl Gustav Jung's psychology. In spite of the fact that physics and psychology are usually considered as unrelated, in the last century, both of these disciplines have led at the same time to revolutionary changes in the Western understanding of the cosmic order, discovering a non-empirical realm of the universe that doesn't consist of material things but of forms. These forms are real, even though they are invisible, because they have the potential to appear in the empirical world and act in it. We present arguments that force us to believe, that the empirical world is an emanation out of a cosmic realm of potentiality, whose forms can appear as physical structures in the external world and as archetypal concepts in our mind. Accordingly, the evolution of life now appears no longer as a process of the adaptation of species to their environment, but as the adaptation of minds to increasingly complex forms that exist in the cosmic potentiality. The cosmic connection means that the human mind is a mystical mind. PMID:25379259

    2010-01-01

    During the Second Iberoamerican Graduate School on Astrobiology interesting debates, between the experts from the biological and physical backgrounds, arose about the probability of the existence of extraterrestrial intelligent beings in the universe. For this reason, it is appropriate to reproduce -for the first time in Spanish- the debate on the subject conducted, in 1995, between Carl Sagan and Ernst Mayr. This debate was organized by Guillermo A. Lemarchand and published in the pages of two consecutive numbers of "Bioastronomy News". Here we reproduce the complete debate, including its original introduction.

  17. Mistaken Identity and Mirror Images: Albert and Carl Einstein, Leiden and Berlin, Relativity and Revolution

    Albert Einstein accepted a "special" visiting professorship at the University of Leiden in the Netherlands in February 1920. Although his appointment should have been a mere formality, it took until October of that year before Einstein could occupy his special chair. Why the delay? The explanation involves a case of mistaken identity with Carl Einstein, Dadaist art, and a particular Dutch fear of revolutions. But what revolutions was one afraid of? The story of Einstein's Leiden chair throws new light on the reception of relativity and its creator in the Netherlands and in Germany.

    2015-01-01

    We will show that Carl Stumpf's interpretation of the concept of probability is best understood as that of an objective Bayesian. First we analyse Stumpf's work in relation to that of his contemporary Johannes von Kries, and after that we will discuss various ways in which Stumpf's probability-concept has been construed. By showing that the construals of Stumpf's account by Hans Reichenbach, Richard von Mises and Andreas Kamlah are unfair - and at some points incorrect - we uncover the aspects that are essential to Stumpf's probability interpretation.

  20. Is our media (still racist?

    Directory of Open Access Journals (Sweden)

    Herman Wasserman

    2011-08-01

    Full Text Available The question requires more than a yes or no answer. If racism exists, it is certainly not for a lack of attempts to rid the media from the shackles of its history under apartheid. Since democracy arrived in South Africa, the media industry has undergone some wide-ranging changes. On the level of ownership and editorial changes, the industry has seen ownership of large media houses pass to black consortia and the appointment of black editors and journalists to previously white-dominated media institutions. On the level of professionalism, the system of self-regulation entered into has attempted to ensure that media content is rid of racist stereotyping. The Press Ombudsman’s code cautions the media to “avoid discriminatory or denigrator references to people's race, colour, ethnicity, religion, gender, sexual orientation or preference, physical or mental disability or illness, or age”, unless it “is strictly relevant to the matter reported or adds significantly to readers' understanding of that matter”. It also warns against hate speech, as does the Broadcasting Complaints Commission of South Africa’s code, based on the values enshrined in the Constitution.
    So do we still need to think about racism in the South African media?

  4. The Langevin Approach: An R Package for Modeling Markov Processes

    CERN Document Server

    Rinn, Philip; Wächter, Matthias; Peinke, Joachim

    2016-01-01

    We describe an R package developed by the research group Turbulence, Wind energy and Stochastics (TWiSt) at the Carl von Ossietzky University of Oldenburg, which extracts the (stochastic) evolution equation underlying a set of data or measurements. The method can be directly applied to data sets with one or two stochastic variables. Examples for the one-dimensional and two-dimensional cases are provided. This framework is valid under a small set of conditions which are explicitly presented and which imply simple preliminary test procedures to the data. For Markovian processes involving Gaussian white noise, a stochastic differential equation is derived straightforwardly from the time series and captures the full dynamical properties of the underlying process. Still, even in the case such conditions are not fulfilled, there are alternative versions of this method which we discuss briefly and provide the user with the necessary bibliography.

    Science.gov (United States)

    Montiel, L

    1997-01-01

    Carl Gustav Carus, one of the originators of a doctrine centered on the unconscious, is an interesting figure from current viewpoints. The doctrine he espoused was psychological, but in addition, the author sought foundations for his thinking in the biological knowledge of his time. The unconscious that Carus postulated was simultaneously biological, material and psychological in nature. Thus the history of psychism--the history of the soul--was related with the individual's and the species's biological history. From this perspective the unconscious was recognized as an indispensable element of rational thought. This theory, which recalls in many aspects that of C.G. Jung, made possible the medical study of psychic life and the revaluation of unconscious factors of psychism which were usually denigrated by modern anthropologists and moralists. PMID:11623549

    Full Text Available In 1917 Rudolf Otto published the book The Sacred and proposing the recognition of the irrational aspect as the foundation and maintainer of religious expression by means of analogies and antonyms that the called the numinous. Later, at a conference in1937, Carl Gustav Jung uses the term numinous to clarify what he meant by religion, recognizing this as an observation on what grabs consciousness, thus extending the idea of the numinous to practice and clinical studies. Victor White, Jung's main collaborator in the field of theology, weaves a critical to Otto and Jung's position front to the understanding of religious phenomena, stating that it presents a unilateralism in recognition that only their irrational sphere supports religion. This article aims to lead to a theoretical discussion as to White's reflections on the idea of numinous, in contrast to the positions of Otto and Jung.

    Science.gov (United States)

    Klotz, Sebastian

    2008-09-01

    The study of acoustics, harmonics and of music has been providing scientific models since Greek Antiquity. Since the early modern ages, two separate cultures began to emerge out of the study of music: a technical acoustics and an aesthetically and philosophically inspired musical criticism. In the writings of Johann Friedrich Herbart (1811) a scientific approach to musical aesthetics and to music perception is taking shape that reinstalls the listening process as a highly complex and logical phenomenon. By opening music for a scientific psychological investigation, Herbart pioneered the physiologically and acoustically grounded seminal work by Hermann von Helmholtz On the sensations of tone (1863) which the author considered a prerequisite for musical aesthetics and music theory. Helmholtz in turn inspired the philosopher and psychologist Carl Stumpf to further investigate musical perception (beginning in 1883). To Stumpf, it provided a paradigm for experimental psychology as mental functions and phenomena could be studied in detail. These functions and phenomena are the actual objects of scientific study in Stumpf's inductive and descriptive psychology. Combining insights from statistics, ethnology, anthropology, psychoacoustics and the cultural history of mankind, Stumpf and his team developed a new blend of science which absorbs styles of reasoning, analytical procedures and academic convictions from natural history, the natural sciences and the humanities but at the same time identifies shortcomings of these approaches that fail to grasp the complexities of psychic functions. Despite their reliance on the quasi-objective phonograph and despite their commitment to objectivity, precision and measurement, mental phenomena relating to tonal perception and to music provided too complex a challenge to be easily articulated and shared by the scientific community after 1900. The essay illustrates these tensions against the background of a history of objectivity. PMID

  10. Carl Schmitt o la imposibilidad de una política secularizada

    Directory of Open Access Journals (Sweden)

    García Alonso, Marta

    2005-06-01

    Full Text Available Carl Schmitt is usually regarded as a critic of modernity for his thesis concerning the theological ascent of the key concepts in the theory of the State. In this paper, l argue that there is more to theology in Schmitt's thought than a mere genealogical issue. As a matter of fact, the sphere of politics is for him prior to the constitution of the State. It is at that initial stage that Schmitt introduces the key categories of his thinking by means of theological analogies -e.g., basic anthropological choices concerning our capability for good or evil are justified by invoking the myth of the original sin. As a result of an in depth discussion of these analogies, I contend that what it is indeed impossible to secularize are the Schmittian theses themselves.

    Carl Schmitt suele ser considerado un crítico de la modernidad por sostener que los principales conceptos de la teoría del Estado son conceptos teológicos secularizados. En este trabajo pretendemos poner de manifiesto que la importancia que Schmitt concede a la teología es aún mayor. En efecto, la secularización se refiere a los conceptos claves de la teoría del Estado, pero la política es previa al Estado. Y para establecer sus categorías, Schmitt se sirve de la teología: el carácter conflictivo o pacífico del hombre remite al pecado original; el dilema amigo/enemigo a la elección entre Dios y el diablo, etc. Exploraremos el .alcance de estas analogías, intentando mostrar el carácter inerradicablemente teológico del pensamiento de Schmitt.

    Lucidi, Annalisa; Langerock, Naomi; Hoareau, Violette; Lemaire, Benoît; Camos, Valérie; Barrouillet, Pierre

    2016-02-01

    The causal role of verbal rehearsal in working memory has recently been called into question. For example, the SOB-CS (Serial Order in a Box-Complex Span) model assumes that there is no maintenance process for the strengthening of items in working memory, but instead a process of removal of distractors that are involuntarily encoded and create interference with memory items. In the present study, we tested the idea that verbal working memory performance can be accounted for without assuming a causal role of the verbal rehearsal process. We demonstrate in two experiments using a complex span task and a Brown-Peterson paradigm that increasing the number of repetitions of the same distractor (the syllable ba that was read aloud at each of its occurrences on screen) has a detrimental effect on the concurrent maintenance of consonants whereas the maintenance of spatial locations remains unaffected. A detailed analysis of the tasks demonstrates that accounting for this effect within the SOB-CS model requires a series of unwarranted assumptions leading to undesirable further predictions contradicted by available experimental evidence. We argue that the hypothesis of a maintenance mechanism based on verbal rehearsal that is impeded by concurrent articulation still provides the simplest and most compelling account of our results.

  16. Carl Wilhelm Scheele, the discoverer of oxygen, and a very productive chemist.

    Science.gov (United States)

    West, John B

    2014-12-01

    Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties. Despite this, his contributions have often been overshadowed by those of Joseph Priestley and Antoine Lavoisier, who also played critical roles in preparing the gas and understanding its nature. Sadly, Scheele was slow to publish his discovery and therefore Priestley is rightly recognized as the first person to report the preparation of oxygen. This being said, the thinking of both Scheele and Priestley was dominated by the phlogiston theory, and it was left to Lavoisier to elucidate the true nature of oxygen. In addition to his work on oxygen, Scheele was enormously productive in other areas of chemistry. Arguably he discovered seven new elements and many other compounds. However, he kept a low profile during his life as a pharmacist, and he did not have strong links with contemporary prestigious institutions such as the Royal Society in England or the French Académie des Sciences. He was elected to the Royal Swedish Academy of Science but only attended one meeting. Partly as a result, he remains a somewhat nebulous figure despite the critical contribution he made to the history of respiratory gases and his extensive researches in other areas of chemistry. His death at the age of 43 may have been hastened by his habit of tasting the chemicals that he worked on. PMID:25281638

  17. Beyond synchronicity: the worldview of Carl Gustav Jung and Wolfgang Pauli.

    Science.gov (United States)

    Donati, Marialuisa

    2004-11-01

    While exploring the phenomena of synchronicity, Carl Gustav Jung became acquainted with the quantum physicist Wolfgang Pauli and eventually began a collaboration with him. During that collaboration Jung's study of synchronistic phenomena underwent a considerable change; prior to the collaboration, Jung had stressed mainly the phenomenological and empirical features of synchronistic phenomena, while in association with Pauli, he focused his attention upon their ontological, archetypal character. Pauli, on the other hand, became increasingly sensitive to the philosophical aspects concerning the unconscious. Jung and Pauli's common reflections went far beyond psychology and physics, entering into the realm where the two areas meet in the philosophy of nature. In fact, as a consequence of their collaboration, synchronicity was transformed from an empirical concept into a fundamental explanatory-interpretative principle, which together with causality could possibly lead to a more complete worldview. Exploring the problematic character of the synchronicity concept has a heuristic value because it leads to the reconsideration of the philosophical issues that drove Jung and Pauli to clear up the conceptual background of their thoughts. Within the philosophical worldview arising from Jung and Pauli's discussions about synchronicity, there are many symbolic aspects that go against mainstream science and that represent a sort of criticism to some of the commonly held views of present day science.

    Görnitz, Thomas

    2014-01-01

    As I learned in many conversations with Carl Friedrich von Weizsäcker, he saw his place in the history of science deriving from his "Theory of Urs". This theory will establish the unity of science on the basis of quantum bits. Any attempts to find some "fundamental bricks"--of whatever kind--must fail because of the antinomies of atomism. An abstract quantum bit is a structure quantum that cannot be conceived as a particle in space and time. However, it is clear, solely for logical reasons, that a quantum bit is an ultimate and indecomposable entity. Weizsäcker's revolutionary goal was--already 50 years ago--to unite quantum theory with cosmology and, on these grounds, proceed to a theory of elementary particles. The article gives a short overview of Weizsäcker's approach to the unity of physics, ending with a brief summary of what has been achieved in that endeavour up to now. PMID:24974600

  19. Economic vs. juristic thinking in Carl Menger’s principles of economics

    Directory of Open Access Journals (Sweden)

    Jandl Gerhard

    2005-01-01

    Full Text Available Austrian Economic School is increasingly being treated as one of the most significant and ever more influential bodies of ideas affecting the contemporary economic science. It is well known that Carl Menger, the founder of the Austrian School, was a lawyer by education. The paper is devoted to the degree to which his legal education influenced his economic theorizing. After a close examination of the Menger’s conceptual apparatus and the epistemological ramifications of the key notions underlying his thinking, the paper concludes that the juristic background of the far-reaching theoretical contributions contained in Menger’s Principles was truly decisive. That holds true despite the fact that Menger only exceptionally utilized the juristic vocabulary. The key ingredients of his theoretical creation? such as the individual autonomy, the coincidence of the wills in concluding a contract the effective protection of property and making transactions based on the individual motivation to further one’s own interests to the utmost? are clearly inspired and in many ways influenced by private law, particularly the doctrines underlying the Roman Law and the Austrian Civil Code.

  20. Carl Friedrich von Weizsäcker major texts in physics

    2014-01-01

    This book presents a collection of texts by the German physicist and philosopher Carl Friedrich von Weizsäcker (1912-2007), for use in seminars on the history, epistemology and structure of physics. Most texts appear in English for the first time. Weizsäcker became famous through his works in physics, mainly in the early development of nuclear physics. Later he would also become well known as a philosopher and analyst of contemporary culture. Texts include the original publications of the “Weizsäcker-Bethe formula” of nuclear masses and the “Bethe-Weizsäcker cycle,” which explains the source of energy in the sun; both were developed by Bethe at the same time and independently of Weizsäcker. Further texts deal with Weizsäcker’s explanation of the origin of planets, his explanation of the “time arrow” in Statistical Mechanics and his analyses of Quantum Mechanics and the structure of physics in general.

    2014-01-01

    Carl Friedrich von Weizsäcker crossed the boundaries separating science, politics and the public sphere. In this he was led by the conviction that scientists in the modern 'technical age' are responsible for consequences resulting from their applied knowledge. Weizsäcker tried to introduce his knowledge into the policy process by advising politicians or by using the public sphere, thus applying pressure on politics. This was not only true for the 'Göttinger Erklärung' in 1957 but also for his engagement in the nuclear energy debate of the 1970s. Influenced by the 'Limits to Growth' discourse, Weizsäcker more and more gravitated towards an ecological world view and increasingly questioned material growth as well as a techno-scientific based understanding of progress. Weizsäcker thought about risks of the technical age in general and of the use of nuclear energy in particular. In the light of a growing fragmentation of scientific authority, Weizsäcker revealed uncertainty as he became fully aware that expertise cannot be based on scientific reason and cannot code the problems in terms of truth, but is inextricably linked with value spheres and contingencies. Nevertheless, his expertise was utilized as he encouraged parts of the Social Democratic Party (SPD) around Erhard Eppler to think about alternatives in energy policy. PMID:24974614

    Full Text Available The aim of the research is to demonstrate the junior pupils' skills development in still life drawing. Being related to the child's cognitive abilities, well-developed linear space perception positively affects the personality and readiness for various activities. Therefore, pupils' acquaintance with the basics of still life drawing in arts classes has both the aesthetic and psychological and intellectual benefits.Methodology is based on the analysis of theoretical concepts of art criticism, psychological and pedagogical works on developing artistic and creative skills of junior pupils, along with the teaching problems of picturing the space in still life drawings. The author carried out the research and experimental work in the Omsk comprehensive schools to identify the age evolution of children's still life drawings.The research results denote the following development stages of junior pupils' skills related to still life picturing: the first stage – still life objects are aligned to the lower paper edge; the second stage – objects are placed on a horizontal line above the lower paper edge, the object plane being parallel to it; the third stage – still life objects are aligned to a single line with the spatial representations of the object planes pictured as a slightly inclined line dividing the paper below the middle of the sheet; the fourth stage – objects are pictured on different heights (above or below each other, the object plane is pictured with two lines reflecting the perspective; the fifth stage – still life objects are pictured on different heights, object overlapping being common and the perspective reflection of the object planes pictured with two or three lines; the sixth stage – objects are placed on different levels, overlapping being obligatory and a multilevel object planes possible.Scientific novelty implies a systematic analysis, description and illustration of development stages of space picturing in children

  14. European coal: still an energy option

    International Nuclear Information System (INIS)

    During the 1980s the European Commission took the decision to restructure the coal industry so as to make it competitive, stabilizing productivity was no longer considered sufficient reason if economic viability was lacking. Security of energy supplies was still, however, considered to be very important. This policy will be affected by the creation of the single market. The European coal industry will shrink but still has a future, not all of the EC's coal needs should be filled by imports for security reasons. In Spain, as elsewhere, coal mining is decreasing, but costs are also being brought nearer to market prices. Some deep mined coal has been replaced by opencasting and underground costs have also been cut. Spanish reserves will still be exploited, according to the National Energy Plan. Spain is also working on clean coal technologies, eg the Puertollano gasification plant and IGCC, as well as CFB at Teruel

  15. ICD and DSM: neuroplasticity and staging are still missing.

    2016-08-01

    The two main diagnostic systems, the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM), have undergone a number of revisions since their first editions: whereas the fifth edition of the DSM has been published in 2013, the eleventh revision of the ICD is expected by 2018. Although the process of harmonization between the 2 systems is still a debated topic, the forthcoming revision of the ICD is seemingly converging toward the DSM approach in regard to the reclassification of a number of disorders. Nevertheless, the 2 systems still exhibit considerable differences, partly due to their different purposes, development and revision processes, and target audiences. Furthermore, while alternative and innovative classification approaches are emerging with the aim of integrating the latest findings from neuroscience and genomics, both the DSM and ICD still fail to incorporate core concepts such as the clinical staging of psychiatric disorders and "neuroprogression," as well as an adequate consideration of endophenotypes.

    2005-09-01

    Currently, small Unmanned Aerial Vehicles (UAVs) are primarily used for capturing and down-linking real-time video. To date, their role as a low-cost airborne platform for capturing high-resolution, georeferenced still imagery has not been fully utilized. On-going work within the Unmanned Vehicle Systems Program at the Idaho National Laboratory (INL) is attempting to exploit this small UAV-acquired, still imagery potential. Initially, a UAV-based still imagery work flow model was developed that includes initial UAV mission planning, sensor selection, UAV/sensor integration, and imagery collection, processing, and analysis. Components to support each stage of the work flow are also being developed. Critical to use of acquired still imagery is the ability to detect changes between images of the same area over time. To enhance the analysts’ change detection ability, a UAV-specific, GIS-based change detection system called SADI or System for Analyzing Differences in Imagery is under development. This paper will discuss the associated challenges and approaches to collecting still imagery with small UAVs. Additionally, specific components of the developed work flow system will be described and graphically illustrated using varied examples of small UAV-acquired still imagery.

  18. Simulation of a single basin solar still

    International Nuclear Information System (INIS)

    A simulation of a simple solar powered water desalination still is attempted in order to investigate its performance and assess the productivity of potable water in different regions in Jordan representing the Rift Valley, high mountains and plateau, and desert. The potable water productivity and unit efficiency were estimated per day, month and year of hourly operation. The results obtained have indicated that maximum annual daily average output of potable water is achieved in Aqaba at the south end of the Rift Valley and at a rate of 5.425 kg/m2, and a minimum output in Ghor Safi at the centre of the Rift Valley with a rate of 4.550 kg/m2. Wadi Dhulail in the eastern desert and Amman in the mountains and plateau region come second and third, respectively, in regards to annual daily average yield of potable water. The still's performance is evaluated in terms of the overall efficiency that has reached as high as 60% in June and as low as 40% in december with the still in Aqaba claiming the best performance.Furthermore, correlations approximating the still's daily output at the various locations based on daily solar radiation levels are proposed.

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

    From 1970 to 1980 Carl Friedrich von Weizsäcker headed the Max-Planck-lnstitut zur Erforschung der Lebensbedingungen der wissenschaftlich-technischen Welt (MPI for the study of the living conditions of the world of science and technology) in Starnberg, jointly with Jürgen Habermas since 1971. From the start, the Max Planck Society regarded the new institute as an experiment that might perhaps be aborted a few years later. This is exactly what happened. With the retirement of Weizsäcker, his section was closed and the whole institute was renamed. In 1981. Habermas resigned, and then the institute was closed. This paper focusses on some of the problem constellations within the institute that partly explain its development and eventual closure: its birth out of the idea of scientific policy advice, the debates within the Max Planck Society and the complex relationship between Weizsäcker and Jürgen Habermas.

    2011-01-01

    This ethereal-looking image of the Orion Nebula was captured using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile. This nebula is much more than just a pretty face, offering astronomers a close-up view of a massive star-forming region to help advance our understanding of stellar birth and evolution. The data used for this image were selected by Igor Chekalin (Russia), who participated in ESO's Hidden Treasures 2010 astrophotography competition. Igor's composition of the Orion Nebula was the seventh highest ranked entry in the competition, although another of Igor's images was the eventual overall winner. The Orion Nebula, also known as Messier 42, is one of the most easily recognisable and best-studied celestial objects. It is a huge complex of gas and dust where massive stars are forming and is the closest such region to the Earth. The glowing gas is so bright that it can be seen with the unaided eye and is a fascinating sight through a telescope. Despite its familiarity and closeness there is still much to learn about this stellar nursery. It was only in 2007, for instance, that the nebula was shown to be closer to us than previously thought: 1350 light-years, rather than about 1500 light-years. Astronomers have used the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile to observe the stars within Messier 42. They found that the faint red dwarfs in the star cluster associated with the glowing gas radiate much more light than had previously been thought, giving us further insights into this famous object and the stars that it hosts. The data collected for this science project, with no original intention to make a colour image, have now been reused to create the richly detailed picture of Messier 42 shown here. The image is a composite of several exposures taken through a total of five different filters. Light that passed through a red filter as well as light from a filter that

    Full Text Available A few years after Kim Jong Un came into office, North Korea is still attracting controversy in the headlines, and political sanctions are still in operation. Despite the harsh measures in place to isolate Pyongyang from sources of money and luxury, the rulers are able to get what they want using front companies or the help of other states. The reasons for this are deeply rooted in the North Korean political structure. A network of high ranking officials, their children, and political minions are grappling for power and wealth. Beside the powerful Kim clan there exist other families in North Korea whose loyalty must be secured with bribes. If the loyalty of the influential families is eroded, the power base of Kim Jong Un is likely to soon diminish. As a result, the North Korean government is searching for sources of money. Illicit drugs may be one solution the ruling regime find attractive to this problem, but there appears to be a twist: struggling ordinary citizens are showing signs that they too are taking part in this illegal enterprise. This is manifested by their willingness to become involved in crime in the same way as the corrupt regime.

  13. Is Still's Disease an Autoinflammatory Syndrome?

    2012-01-01

    Full Text Available Systemic juvenile idiopathic arthritis (sJIA, formerly called Still's disease, is officially classified as a subset of juvenile idiopathic arthritis (JIA. Beside arthritis, it is characterized by prominent systemic features and a marked inflammatory response. Even if it is still included in the group of juvenile arthritides, sJIA is set apart from all the other forms of JIA. This disorder has markedly distinct clinical and laboratory features suggesting a different pathogenesis. sJIA does not show any association with HLA genes or with autoantibodies and is characterised by an uncontrolled activation of phagocytes with hypersecretion of IL-1 and IL-6. Based on clinical and laboratory features, as well as on new acquisitions on the pathogenesis, it seems evident that sJIA is an autoinflammatory disease related to abnormality in innate immune system. The new insights on the pathogenesis of sJIA have therefore dramatically changed the approach to treatment, with the development of targeted treatments (anti-IL-1 and anti-IL-6 agents more effective and safer than earlier medications.

    Duerbeck, H. W.; Hansel, C.; Munzel, G.; Ilgauds, H.-J.; Borngen, M.

    2006-12-01

    The biography of the former member of the Saxonian Academy of Sciences, Carl Christian Bruhns, and appropiately published in their Transactions, originated from a series of lectures given some years ago. Gisela Munzel and Hans-Joachim Ilgauds, who have already written an authoritative history of Leipzig observatories, joined geophysicist Michael Borngen to describe various aspects of Bruhns' life and activities in different scientific fields. For the astronomical reader, Gisela Munzel's contribution is certainly the most rewarding one, and it covers almost the complete first half of the book. She not only describes Bruhns' astronomical career, but also supplies many details of his life. Having passed something equivalent to a junior high school, his father urged him to become apprentice in his own field, that of a locksmith. C.C. Bruhns became a mechanic in several companies in Berlin, and started also part-time work as a computer at Berlin Observatory in 1851. He soon was "discovered" by its director Johann Franz Encke, and became second assistant in mid-1852, first assistant in 1854 and observer in 1855. In mid-1856 he received his PhD on the topic of minor planets. A prize assignment on astronomical refraction developed into his habilitation thesis of 1859. When in 1857 the observer Heinrich d'Arrest left Leipzig Observatory, there were plans to replace him by an astronomer who would later also take over the post of the aging August Ferdinand Mobius. There were already plans to move the old Observatory on the tower of Pleissenburg castle to another location, when Bruhns was appointed observer and professor in April 1860. In Summer, construction of the new Observatory at Johannistal started, and it was inaugurated in late 1861. Munzel faithfully traces his work, his assistants and colleagues - Engelmann, Weinek, Zollner, and many more - , his activities in the founding of the Astronomische Gesellschaft, his work as a commissar of the ``Mitteleuropaische

    We describe the case of a 39-year-old Caucasian woman who was admitted to the University Hospital of Antwerp with a clinical picture suggestive of adult Still's disease. Even though a transoesophageal echocardiography showed endocarditis of the aortic valve, blood cultures remained negative. Additional serological testing revealed a positive result for Bartonella henselae. Histology of the supraclavicular lymph node showed a reactive lymph node with a positive polymerase chain reaction (PCR) for Bartonella henselae. Prednisolone treatment was started in a dosage of 10 mg per day and rifampicin 600 mg/d in combination with doxycyclin 200 mg/d was given for 6 months. During therapy the patient gradually improved and signs of endocarditis disappeared on echocardiography. PMID:18714850

    2015-06-01

    Worldwide demographic changes mean that older people represent a significant group of patients for nurses everywhere. Ageism is increasingly recognised as an issue among healthcare professionals and evidence suggests that problems with quality of care remain. Nursing curricula have to address the needs of an ageing population in a variety of settings, reflect the importance of therapeutic care and explore nursing students' attitudes, in order to provide them with the appropriate skills to meet the needs of older people. This article debates the main factors influencing gerontological content in nursing curricula and suggests that ageism is still evident in nurse education. A variety of strategies are identified to assist in developing appropriate curriculum content. PMID:26018487

    2010-01-01

    Full Text Available This article focuses on the question of whether the latest results achieved in sciences such as evolution studies and brain research can help us understand the nature of aesthetic judgments. It suggests that such approaches may offer interesting insights for understanding many problems in aesthetics, but for clarifying aesthetic judgments one needs a philosophical point of view. Aesthetic judgments cannot be proven right or wrong by scientific methods, and beauty or other aesthetic qualities cannot be directly measured. The “method” of both making and analyzing aesthetic judgments is discussion, and the article clarifies why this is still the case, even if empirical, non-philosophical scientific methods are more accurate than ever before.

  18. Fuel particles still dominate the Chernobyl scene

    International Nuclear Information System (INIS)

    The uniqueness of the Chernobyl accident in 1986 from an environmental perspective lay in the fact that so much radioactive material was discharged to atmosphere in the form of solid particles of fuel ('hot particles'). Intact fuel particles can still be found on land in Belarus and Ukraine even ten years after the accident. On undisturbed land, there has been little downward migration and most of the particles and radionuclides leached from them are still within about 5 cm of the soil surface. For a given level of deposition, the soil-to-plant transfer on particle-contaminated land has apparently been less than where the radionuclides came from weapons fallout or were applied in aqueous solutions in controlled experiments. Soon after the accident, it was shown that radioisotopes of cesium and strontium would be leached at similar rates. However, the strontium would become increasingly available for root-uptake, but, on most soils, the cesium would be rapidly 'fixed' and its availability for root-uptake by plants would be limited. This indeed has proved to be the case. 137Cs levels in grass and arable crops have remained roughly constant since about 1990, but 90Sr levels have shown a consistent yearly increase. The presence of fuel particles on land inside a 30 km restriction zone around Chernobyl site will be a major consideration in any planning of land reclamation. Even beyond the 30 km zone, the presence of fuel particles is an important factor to consider in radioecological research, environmental monitoring, and remediation. (author) 2 tabs., 25 refs

    Full Text Available Dengue is currently listed as a "neglected tropical disease" (NTD. But is dengue still an NTD or not? Classifying dengue as an NTD may carry advantages, but is it justified? This review considers the criteria for the definition of an NTD, the current diverse lists of NTDs by different stakeholders, and the commonalities and differences of dengue with other NTDs. We also review the current research gaps and research activities and the adequacy of funding for dengue research and development (R&D (2003-2013. NTD definitions have been developed to a higher precision since the early 2000s, with the following main features: NTDs are characterised as a poverty related, b endemic to the tropics and subtropics, c lacking public health attention, d having poor research funding and shortcomings in R&D, e usually associated with high morbidity but low mortality, and f often having no specific treatment available. Dengue meets most of these criteria, but not all. Although dengue predominantly affects resource-limited countries, it does not necessarily only target the poor and marginalised in those countries. Dengue increasingly attracts public health attention, and in some affected countries it is now a high profile disease. Research funding for dengue has increased exponentially in the past two decades, in particular in the area of dengue vaccine development. However, despite advances in dengue research, dengue epidemics are increasing in frequency and magnitude, and dengue is expanding to new areas. Specific treatment and a highly effective vaccine remain elusive. Major research gaps exist in the area of integrated surveillance and vector control. Hence, although dengue differs from many of the NTDs, it still meets important criteria commonly used for NTDs. The current need for increased R&D spending, shared by dengue and other NTDs, is perhaps the key reason why dengue should continue to be considered an NTD.

I argue that although the meaning and role of place have been changed, place still is an important concept in ethnology. Researches are now paying more attention to the changed nature of the concept, e.g. for the multivocality of places. The anthropological literature on space and place forms my theoretical framework, with which I study some empiric cases from my familiar environment, from Finnish Lapland and from Kola Peninsula. ‘Place’, in my examples the sieidi of Taatsi, Lake Seidjavr, the Pallas fells or the tourist centre Levi, can have a unique reality for each inhabitant and visitor. While the meanings may be shared with others, the views of the place are often likely to be competing, and contested in practice. According to Margaret Rodman (2004: 207, researchers should empower place by returning control over meanings of place to the rightful producers, and empower their own analysis of place by attending to the multiplicity of local voices found about place.

  2. How if petroleum still had a future

    International Nuclear Information System (INIS)

    Despite the oil spill that hits the Gulf of Mexico since April 2010, oil firms are still going on with their technological quest to postpone the hydrocarbons exhaustion. The goal is to increase the reserves by exploiting the less accessible resources. Giving a precise estimation of oil reserves is practically impossible as the capacities announced by the main producers are extremely disputed. They are in general ranging from 960 to 1060 billions of barrels, i.e. 32 to 35 years of actual consumption (deep offshore and heavy oil reserves not included). On the contrary, gas reserves are well known. They are estimated to 175 Tm3, which corresponds to 60 years of actual consumption. Additional non-conventional gas reserves represent 900 Tm3, from which 4% are accessible today. Before starting to develop new fields, companies try to fully exploit the existing fields using enhanced recovery technologies. In 2009 the petroleum investments have weakened in all sectors except in offshore exploitation. However, the recent accident of the Deepwater Horizon platform in the Gulf of Mexico has brought the safety question to the forefront. (J.S.)

    Feline infectious peritonitis (FIP) is one of the most important fatal infectious diseases of cats, the pathogenesis of which has not yet been fully revealed. The present review focuses on the biology of feline coronavirus (FCoV) infection and the pathogenesis and pathological features of FIP. Recent studies have revealed functions of many viral proteins, differing receptor specificity for type I and type II FCoV, and genomic differences between feline enteric coronaviruses (FECVs) and FIP viruses (FIPVs). FECV and FIP also exhibit functional differences, since FECVs replicate mainly in intestinal epithelium and are shed in feces, and FIPVs replicate efficiently in monocytes and induce systemic disease. Thus, key events in the pathogenesis of FIP are systemic infection with FIPV, effective and sustainable viral replication in monocytes, and activation of infected monocytes. The host's genetics and immune system also play important roles. It is the activation of monocytes and macrophages that directly leads to the pathologic features of FIP, including vasculitis, body cavity effusions, and fibrinous and granulomatous inflammatory lesions. Advances have been made in the clinical diagnosis of FIP, based on the clinical pathologic findings, serologic testing, and detection of virus using molecular (polymerase chain reaction) or antibody-based methods. Nevertheless, the clinical diagnosis remains challenging in particular in the dry form of FIP, which is partly due to the incomplete understanding of infection biology and pathogenesis in FIP. So, while much progress has been made, many aspects of FIP pathogenesis still remain an enigma. PMID:24569616

    Full Text Available AbstractIn September 1837 the centennial celebrations of Göttingen university took place; Alexander von Humboldt, who visited Göttingen for this purpose, and Carl Friedrich Gauss created the project: Do showers of meteors influence the terrestrial magnetic phaenomena, comparable to the aurora borealis? The investigation should take place in November 1837, when strong meteor showers were once again expected. In this context the letter of Humboldt to Gauss from November 30, 1837 is of great importance; in this letter two enclosures were mentioned which still exist, but which were not presented in the edition of the letters between Humboldt and Gauss.One of these enclosures is a letter from Boguslawski to Humboldt from November 15, 1837, on which Humboldt made several remarks. Boguslawski was astronomer at the observatory of Breslau. The other enclosure was a document, containing the observation data of Humboldt and Herter, which were made in Berlin during November 12 to 15 and 21. These two documents together with the historical context are presented here for the first time, accompanied by the report by Gerling on meteor showers observed in Marburg from November 12 to 14.ZusammenfassungWährend der im September 1837 in Göttingen stattfindenden Universitätsfeierlichkeiten initiierten Alexander von Humboldt und Carl Friedrich Gauß gemeinsam ein Projekt; es ging dabei um die Frage, ob Sternschnuppen die erdmagnetischen Erscheinungen beeinflussen würden, dem Nordlicht vergleichbar.

  14. THORP - still time to stop it

    International Nuclear Information System (INIS)

    British Nuclear Fuels (BNFL) applied for a revised site discharge authorisation in April 1992. It will apply to all discharges from existing Magnox reprocessing, and from new plants such as EARP (The Enhanced Actinide Removal Plant) and THORP (Thermal Oxide Reprocessing Plant). BNFL's application will be considered by Her Majesty's Inspectorate of Pollution (HMIP) and the Ministry of Agriculture, Fisheries and Food (MAFF). As part of the reauthorisation process BNFL has to demonstrate that it has complied with the Government's policy on radioactive waste management. The cornerstone of this policy is that any practice producing radioactive waste must be justified. This means that ''the need for the practice must be established in terms of its overall benefit''. However reprocessing is not justified. Consequently, any level of additional radiation exposure from future discharges cannot be considered acceptable. HMIP should refuse to grant a new authorisation for the site. (author)

  15. Consumer approval of irradiated meat still tentative

    International Nuclear Information System (INIS)

    Although the FDA has approved irradiation of red meat, consumers may not be so accepting of the use of this technology. Irradiation is a process used to improve food safety in food products susceptible to disease-causing microorganisms. The red meat ruling was widely praised by federal officials and food industry leaders, but consumers seem less sure. Indeed, on the night of the red meat announcement last December, CBS Evening News reported that over 70 percent of U.S. consumers would not knowingly eat irradiated food. There is hope, however, as a study by the Center for Consumer Research at the University of California, Davis, revealed that consumer interest in buying irradiated food can be substantially improved by providing consumers with information, thereby enabling them to see the benefits and to overcome the myths of irradiation

    In recent years nursing documentation has been one of the most important development areas of nursing informatics (NI) in Finland. The purpose of this study is to describe the development of the nurse educators' competences in nursing documentation during a project called eNNI. The eNNI project (2008-2010) was a cooperative project by nurse educators and working life experts. The goal of the project was to implement the national documentation model and thereby improve operational processes at workplaces. The study includes pre- and post-test questioning of NI applications with a web-based questionnaire (n=136). The data were analyzed with distribution, cross-tabulations and average tests and descriptive statistic multivariate method. According to the results, the ICT skills of the nurse educators were good at the end of the project, and they had good information literacy competence. On the other hand, their advanced NI skills left room for improvement. PMID:22874332

  18. Entre Carl Schmitt y Thomas Hobbes . Un es tudio del liberalismo moderno a partir del pensamiento de Leo Strauss

    Directory of Open Access Journals (Sweden)

    José Daniel Parra Quintero

    2010-01-01

    Full Text Available El presente ensayo es una lectura sobre el liberalismo moderno desde el pensamiento de Leo Strauss. A partir de su análisis del Concepto de lo político de Carl Schmitt y su crítica de la "despolitización y neutralización" liberal, Strauss responde con una afirmación del problema del derecho natural, para lo cual es fundamental como primer paso estudiar la filosofía política de Thomas Hobbes. Desde allí Strauss se plantea un punto de contraste hacia una consideración clásica del derecho natural que pueda hacer frente al nihilismo político o cosmopolitanismo apolítico en la modernidad tardía, resultado ambos tanto del histori-cismo radical como del positivismo metodológico. Strauss antepone a la afirmación de la voluntad del poder soberano la búsqueda del derecho natural como representación de la idea de la justicia.

    Full Text Available Carl Schmitt is usually perceived as the theorist of total state, total war and total hostility. In the article, the author however tries to show that from 1937 to 1944, Schmitt was arguing that total war and total hostility were dangerous for Germany (as well as for the rest of Europe and warned against perpetuation of all efforts to totalize enemy that started in 1914. In his theoretical endeavors in this period there was place for the total state only - and especially for the total state strong enough to resist temptation of declaring total war on total enemy. The total state he recommended Hitler and his Nazi comrades was German Reich, as a part of Europe ordered and divided in the huge spaces (Grossraumordnung. Positioned in the centre of Europe, between the rest of the powers (France, Italy, USSR as well as the Scandinavian states, Germany should be careful enough to wage war only against its Eastern enemies (Poland and maybe USSR and only in order to achieve 'just' borders. Occupying in this way its huge space Germany should devote itself to the task of exploitation of various peoples such as Poles, Chechs and Slovaks, which were perceived as incapable of having their states and doomed to serve the master race - the Germans.

  2. STAT3 the oncogene - still eluding therapy?

    Wake, Matthew S; Watson, Christine J

    2015-07-01

    The STAT family of transcription factors (signal transducers and activators of transcription) transduce signals from cytokine receptors to the nucleus, where STAT dimers bind to DNA and regulate transcription. STAT3 is the most ubiquitous of the STATs, being activated by a wide variety of cytokines and growth factors. STAT3 has many roles in physiological processes such as inflammatory signalling, aerobic glycolysis and immune suppression, and was also the first family member shown to be aberrantly activated in a wide range of both solid and liquid tumours. STAT3 promotes tumorigenesis by regulating the expression of various target genes, including cell-cycle regulators, angiogenic factors and anti-apoptosis genes. Paradoxically, in some circumstances, STAT3 signalling induces cell death. The best known example is the involuting mammary gland, where STAT3 is essential for induction of a lysosomal pathway of cell death. Nevertheless, direct silencing or inhibition of STAT3 diminishes tumour growth and survival in both animal and human studies. This suggests that abolishing STAT3 activity may be an effective cancer therapeutic strategy. However, despite this potential as a therapeutic target, and the extensive attempts by many laboratories and pharmaceutical companies to develop an effective STAT3 inhibitor for use in the clinic, no direct STAT3 inhibitor has been approved for clinical use. In this review, we focus on the role of STAT3 in tumorigenesis, and discuss its potential as a therapeutic target for cancer treatment. PMID:25825152

    Image compression for both still and moving images is an extremely important area of investigation, with numerous applications to videoconferencing, interactive education, home entertainment, and potential applications to earth observations, medical imaging, digital libraries, and many other areas. We describe work on a neural network methodology to compress/decompress still and moving images. We use the 'point-process' type neural network model which is closer to biophysical reality than standard models, and yet is mathematically much more tractable. We currently achieve compression ratios of the order of 120:1 for moving grey-level images, based on a combination of motion detection and compression. The observed signal-to-noise ratio varies from values above 25 to more than 35. The method is computationally fast so that compression and decompression can be carried out in real-time. It uses the adaptive capabilities of a set of neural networks so as to select varying compression ratios in real-time as a function of quality achieved. It also uses a motion detector which will avoid retransmitting portions of the image which have varied little from the previous frame. Further improvements can be achieved by using on-line learning during compression, and by appropriate compensation of nonlinearities in the compression/decompression scheme. We expect to go well beyond the 250:1 compression level for color images with good quality levels.

    With the rapid development of semiconductor technology, highly integrated circuits (ICs) and future nano-scale devices require large diameter and defect-free monocrystalline silicon wafers. The ongoing innovation from silicon materials is one of the driving forces in future micro and nano-technologies. In this work, the recent developments in the controlling of large diameter silicon crystal growth processes, the improvement of material features by co-doping with the intend-introduced impur-ities, and the progress of defect engineered silicon wafers (epitaxial silicon wafer, strained silicon, silicon on insu-lator) are reviewed. It is proposed that the silicon man-ufacturing infrastructure could still meet the increasingly stringent requirements arising from ULSI circuits and will expand Moore's law into a couple of decades.

    Science.gov (United States)

    2010-01-01

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

    2002-12-01

    The Earth and life have evolved in tandem; It is impossible to separate the two over most of geologic time. Geological and geochemical processes create and define the conditions necessary for life. In turn, life has shaped geological processes in ways that are understood, and ways that are not yet understood. The reciprocal interaction between the planet and its inhabitants has driven changes in the molecules, metabolisms, and morphologies of terrean organisms. Today, with the emergence of complete genome sequences and tools from molecular biology, we are now better able, more than ever before, to tell stories of how we came to be, on a planet and in a cosmos that has both nourished us and (from time to time) threatened to extinguish us. The stories to be told in this talk combine information from the geological and paleontological records, analysis of genome sequence data, and experiments that resurrect ancient, extinct life forms for study in the laboratory. The talk will emphasize the non-recurring, progressive feature of the dance between Earth and Life. We will show how the emergence of humans was influenced by the environment, and how humans placed their irreversible mark on the genes of organisms that they touched. We will show how the global environmental crisis that began in the Oligocene irreversibly transformed the plant and animal kingdoms. We will proceed back to the Cretaceous, to explore how plants and dinosaurs influenced each other, and the genomes of surviving fungus and flies. From there we will go to the Jurassic, as the first placental mammals reconstructed their reproductive systems in response to the planetary changes. We will ask how cosmic events, from asteroids to supernova, may have influenced life on Earth. We will ask what consequential features of life that we see around us might be unique to Earth, and what features might be found universally in life elsewhere. The talk will also review some of the methodological issues associated

  16. Experimental investigation of stepped solar still with continuous water circulation

    International Nuclear Information System (INIS)

    Highlights: • Comparison between modified stepped and conventional solar still was carried out. • Effect of storage tank and cotton absorber on productivity was investigated. • Efficiency for modified stepped still is higher than conventional still by 20%. • The day and night efficiency increases by 5% and 3.5% for salt and sea water. - Abstract: This paper presents a modification of stepped solar still with continuous water circulation using a storage tank for sea and salt water. Total dissolved solids (TDS) of seawater and salt water before desalination is 57,100 and 2370 mg/l. A comparison study between modified stepped and conventional solar still was carried out to evaluate the developed desalination system performance under the same climate conditions. The effect of installing a storage tank and cotton black absorber for modified stepped solar still on the distillate productivity was investigated. The results indicate that, the productivity of the modified stepped still is higher than that for conventional still approximately by 43% and 48% for sea and salt water with black absorber respectively, while 53% and 47% of sea and salt water, respectively with cotton absorber. Also, the daily efficiency for modified stepped still is higher than that for conventional still approximately by 20%. The maximum efficiency of modified stepped still is occurring at a feed water flow rate of 1 LPM for sea water and 3 LPM for salt water. Total dissolved solids (TDS) of seawater and salt water after desalination is 41, and 27 mg/l

  17. America's First Carl Sagan: Ormsby MacKnight Mitchel, Pre-Civil War Astronomer and Lecturer on the Cosmos

    Osterbrock, D. E.

    2002-12-01

    In the years before television, videos, radio. movies, or even loudspeakers, Ormsby MacKnight Mitchel (1809-1862) was the best-known popularizer of astronomy and the scientific study of the universe in nineteenth-century America. Each winter he traveled the country by railroad, steamer, and stagecoach, speaking to large paying crowds in principal cities from Boston, New York, and Philadelphia through Cincinnati to New Orleans on the cosmos and our place in it, with special attention to possible inhabitants of planers orbiting other stars. Mitchel had much the same attraction as Sagan did in our time, and awakened many people's interest in astronomy through the human angle, as Carl did. His argument was simple, and according to Frank Triplett goes back thousands of years: other stars are suns, our sun has planets with people on one of them, why should not other stars also have populated planets? But first Mitchel, like Sagan, always explained clearly the discoveries of astronomy that fleshed out this argument with facts. He emphasized the ``clockwork universe", governed by gravity, that Newton, Herschel, and Laplace had investigated and found to be stable. There were many other similarities between these two great popularizers. Mitchel's base was the Cincinnati Observatory, which he had founded, raising the funds for it himself in small contributions from hundreds of ``members", which he publicised as far more democratic than support from European kings and lords. He went abroad to get a telescope, and finally found his ``Great [12-inch] Refractor" in Munich, with help from John Quincy Adams, Astronomer Royal George Biddle Airy, and Paris Observatory Director Fracois Arago, in spite of a rebuff by President John Tyler. These episodes have similarities in Sagan's lobbying NASA for close-up images of Mars. Views of other American professional astronomers on life on other worlds will also be described briefly, from Denison Olmsted, Elias Loomis, Charles A. Young (who

  19. Rapeseed is an efficient energy crop which can still improve

    2007-11-01

    Full Text Available The ability of biofuels to contribute efficiently to the replacement of fossil energy and to the reduction of greenhouse gas emissions has been a matter of debate. Hence, there is a need to assess accurately the energy balance of biofuels and their ability to reduce greenhouse gas emissions, in order to evaluate and to improve the benefit for society. In rapeseed, the energy ratio (energy produced per unit of non-renewable energy input is well above 2 whatever the method of calculation. In order to investigate the variability of energy ratios and to identify ways of improvement, a study was conducted in France in 2005 and 2006. The method of mass allocation of input energy was used for calculations, instead of the substitution method, because with this method the results do not depend on the utilization of co-products. Hence, this method is better adapted to follow improvements. A great variability in the energy ratio was observed in 2005 and 2006. Seed yields and energy cost of fertilizer N explained most of this variability. Hence, improvements should focus on increasing yield with little increase in energy cost, and on decreasing wasting of N fertilizer. However the farmer incomes, and the net production of energy per hectare, must also be a matter of concern. The inventories of greenhouse gas emissions of biofuels are still uncertain because of the great variability of soil emissions, due to environmental and management factors. Hence, in order to assess the effect of rapeseed on greenhouse gas emissions, methods based on process-oriented models accounting for these factors must be used. Such models give promising results, but further testing is still needed.

  20. Single basin solar still with fin for enhancing productivity

    International Nuclear Information System (INIS)

    Distilled water productivity of the single basin solar still is very low. In this work, to augment evaporation of the still basin water, fins were integrated at the basin of the still. Thus production rate accelerated. Also, for further increase in exposure area sponges were used. Experimental results were compared with ordinary basin type still and still with wicks. The governing energy balance equations were solved analytically and compared with experimental results. It was found that 29.6% productivity increased, when wick type solar still was used, 15.3% productivity increased when sponges were used and 45.5% increased when fins were used. A good agreement had been achieved with theoretical results

    Full Text Available Solar distillation mimics nature’s hydrologic water cycle by purify water through evaporation as well as condensation. It is one of the most basic purification systems available today to get high quality of drinking water and can remove non-volatile contamination from almost any water source. Solar still is a one kind of solar distillation system in which brackish or impure water converted into drinkable water. Here, three solar stills have developed by locally available materials. The first one is a conventional type and the second solar still is consists of Aluminum plate while the third one consists of Galvanized iron. Here, experiment performed to get higher distillate output from solar still. Experiments represent that, solar still consists of aluminum plate gives 30 % more output compared with conventional solar still and Galvanized iron plate inside solar still gives 12% more output compared with conventional solar still. Hence, Aluminum plate is the best plate to obtain higher distillate output from solar still.

  3. Iron: Protector or Risk Factor for Cardiovascular Disease? Still Controversial

    Directory of Open Access Journals (Sweden)

    Antonio García-Rodríguez

    2013-07-01

    Full Text Available Iron is the second most abundant metal in the Earth’s crust. Despite being present in trace amounts, it is an essential trace element for the human body, although it can also be toxic due to oxidative stress generation by the Fenton reaction, causing organic biomolecule oxidation. This process is the basis of numerous pathologies, including cardiovascular diseases (CVD. The relationship between iron and cardiovascular disease was proposed in 1981 by Jerome Sullivan. Since then, numerous epidemiological studies have been conducted to test this hypothesis. The aim of this review is to present the main findings of the chief epidemiological studies published during the last 32 years, since Sullivan formulated his iron hypothesis, suggesting that this element might act as a risk factor for cardiovascular disease. We have analyzed 55 studies, of which 27 supported the iron hypothesis, 20 found no evidence to support it and eight were contrary to the iron hypothesis. Our results suggest that there is not a high level of evidence which supports the hypothesis that the iron may be associated with CVD. Despite the large number of studies published to date, the role of iron in cardiovascular disease still generates a fair amount of debate, due to a marked disparity in results.

  7. STILLING BASINS BELOW OUTLET WORKS – AN OVERVIEW

    Directory of Open Access Journals (Sweden)

    H L Tiwari,

    2010-11-01

    Full Text Available A stilling basins are transition structures constructed to dissipate excess energy confined by high velocity flow at the outlet of conduit or tunnel so that the flow beyond the basin does not endanger the stability of bed and banks of downstream channel. In a stilling basin kinetic energy causes turbulences and it is ultimately lost as heat and sound energy. there are several types of stilling basins which are used in various hydraulic structures like dam, canal, culvert etc. The type of stilling basin most suitable at a particular location mainly depends upon initial Froude Number and initial velocity of flow. This paper covers design principles and features of various stilling basins used for outlet works.

  8. Modelling radiative heat transfer inside a basin type solar still

    International Nuclear Information System (INIS)

    Radiative heat transfer inside a basin type solar still has been investigated using two models with (model 1) and without (model 2) taking into account optical view factors. The coefficient of radiative heat exchange (hr,w-gc) between the water and cover surfaces of a practical solar still was computed using the two models. Simulation results show that model 1 yields lower values of hr,w-gc and the root mean square error than model 2. It is therefore concluded that the accuracy of modelling the performance of a basin-type solar still can be improved by incorporating view factors. - Highlights: • Radiative heat transfer in a basin type solar still has been investigated. • Two models with and without view factors were used. • The model with view factors exhibits a lower magnitude of root mean square error. • View factors affect the accuracy of modelling the performance of the solar still

  9. Comparative performance of aluminium copper and iron solar stills

    International Nuclear Information System (INIS)

    Three different metal sheets have been used in the fabrication of three different single sloping solar stills of the same surface geometry. The metals were galvanized iron, aluminium and copper. This paper presents the performance of the different stills operating under the same environmental conditions. The observed distillate yields was greatest for copper, then aluminium and lastly, iron still. The differences in the yields is attributed to the differences in the thermal conductivities of the metals. The equivalent local costs for the fabrication of the copper, aluminium and iron stills are respectively $160, $95 and $60. Taking the long run costs into consideration, the copper still is preferred because of its availability, durability, weldability and relatively higher conductivity of 380Wm-1K-1 value.

    2012-10-01

    Solar still desalination uses a sustainable and pollution-free source to produce high-quality water. The main limitation is low productivity and this has been the focus of intensive research. A major concern while increasing productivity is to maintain economic feasibility and simplicity. The authors present a critical review of the research work conducted on solar stills development. Studies addressing each parameter of concern are grouped together and results compared. Novelty in design and newly introduced features are presented. Modeling efforts of flow circulation within the still and methods to estimate internal heat transfer coefficients are discussed and future research needs are outlined. © 2012 Taylor & Francis Group, LLC.

  14. Public trust and better communication is still needed

    International Nuclear Information System (INIS)

    Korean nuclear regulatory agency (KINS) has recently changed its 'safety philosophy': The final goal of nuclear safety should he achievement of psychological and emotional security of people rather than simple attainment of engineering safety targets. This significant progress is not widely known for public. But, its new attitude was confirmed when a nuclear reactor for research purpose, which was located in a metropolitan city, leaked a small amount of radioactive materials in 2005. The agency focused on the fact itself that radioactive materials were released into environment although its amount of radioactivity was negligible from engineering perspective. Does this mean that 'science-technology centrism' which has widely pervaded nuclear circle begin to collapse from the regulatory agency? There has been certain degree of advancement in openness of information, increasing transparency, communication efforts toward public and local. people. However, it should he noted that regulatory activity has not attained enough trust from public. Four points are pointed out for regulatory agency to get further people's trust. First, nuclear agency's institutional independence is still uncertain. The Ministry of Science and Technology, which is in charge of nuclear safety by controlling KINS, at the same time promotes nuclear industry by managing nuclear R and D activities. Cultural aspects should also be noted. People tend to regard regulatory agency as 'friends' of nuclear. Second, regulatory activities are passive and not preventive in many cases. It is needed to make people convince that the regulatory agency defend their interest first when it competes with the interest of industry. Third, communication with public is lacking. Even transparent procedure and openness of information may result in limiting public access if its content and meaning are not fully communicated. Fourth, knowing more about media is needed. Understanding news production processes may contribute to

  15. Simulation study of a capillary film solar still coupled with a conventional solar still in south Algeria

    International Nuclear Information System (INIS)

    Highlights: • Coupling in series a capillary film solar still and a conventional solar still. • Combined heat and mass transfer analyses in solar distillation systems. • Design parameters of the system are optimized by simulation program. - Abstract: This work presents a numerical simulation of capillary film solar still (distiller) coupled in series with another conventional solar still. Different transfer phenomena of heat and mass are considered to evaluate the daily distillate production. The study takes into account the quality of brackish water with moderate salinity in Adrar city (south of Algeria). The performance of the system is evaluated and compared with that of conventional solar still under the same meteorological conditions. A numerical simulation is carried out to appreciate the developed model and to optimize the relationship between both distillers collecting surfaces. The obtained results show that the system daily production is at 54–83% higher than that of the conventional one. In addition, some parameters influences are studied to define the optimal operating conditions for the present system. For the first solar still, the inclination angle and surfaces ratio have a significant effect on distillate production. Brine flow rate and wind speed have slight effect on still production

    At this moment in thousands of process heaters all over the world there are, to borrow a phrase from the late Carl Sagan, 'billions and billions' of Btu/hr beneficially being released entirely free of pulsation. On those few occasions, perhaps a dozen and a half in my career, when I would get the inevitable 'Why me?' call, I have generally responsed with something like, 'Consider yourself lucky, you have a rare scientific curiosity on your hands'. Reflecting on the solutions ultimately found, I'm reminded that many years ago my friend Abbott Putnam shared with me an early AGA (American Gas Association) field-service bulletin that included a prescription for eliminating combustion-driven oscillations in home heating units; viz., 'Drill a hole; if that doesn't work, drill another hole' or words to that effect. Many times have I wished that I still had a copy of that bulletin and in this paper we will have occasion, once again, to reflect upon the value of that advice. In this paper we will discuss an instance that arose in a pioneering installation of a breakthrough development of 'extremely', to distinguish it from 'ultra', low-NOx lean premix burner technology. We will illustrate how, when and under what circumstances combustion-driven oscillation can arise; we will touch on the many alternatives for its elimination that were considered and investigated; and we will discuss three practical alternatives for eliminating combustion-driven oscillations.

    Science.gov (United States)

    Krohn, Wolfgang

    2014-01-01

    In the Starnberg Max-Planck Institute one of the working groups was concerned with science as the formative condition--or "hard core"--of societal modernity, and with science as potential resource for solving social problems and addressing future goals. More precisely, the group intended to differentiate between phases in which scientific disciplines predominantly care for their own paradigmatic completion and those allowing their theoretical potential resonate with external needs. The conceptual model was coined "finalization in science". It soon provoked a heated controversy on the dangers of social control of science. The paper analyses Carl Friedrich von Weizsäcker's views on the relation between philosophy and policy of science including his interpretation of Thomas Kuhn and reconstructs the impact of his ideas on the finalization model. It finally reflects on the relationship between science development and change of consciousness in the context of scientific responsibility for (the use of) research outcomes. PMID:24974608

    Decker, Peter

    2016-01-01

    Abstract This study documents the first detailed phylogenetic analysis of an Australian paradoxosomatid millipede genus. Two mitochondrial genes (partial COI and 16S) as well as partial nuclear 28S rDNA were amplified and sequenced for 41 individuals of the southeastern Australian genus Pogonosternum Jeekel, 1965. The analysis indicates that five species groups of Pogonosternum occur across New South Wales, Victoria and Tasmania: Pogonosternum nigrovirgatum (Carl, 1912), Pogonosternum adrianae Jeekel, 1982, Pogonosternum laetificum Jeekel, 1982 and two undescribed species. Pogonosternum coniferum (Jeekel, 1965) specimens cluster within Pogonosternum nigrovirgatum. Most of these five species groups exhibit a pattern of high intraspecific genetic variability and highly localized haplotypes, suggesting that they were confined to multiple Pleistocene refugia on the southeastern Australian mainland. The phylogenetic data also show that northwestern Tasmania was colonized by Pogonosternum nigrovirgatum, probably from central Victoria, and northeastern Tasmania by an as yet undescribed species from eastern Victoria.

    International Nuclear Information System (INIS)

    The 50th anniversary of the first nuclear explosion (16th July 1945) prompted the editor of this collection to look again at the part played by German physicists in the nuclear weapons issue. Carl Friedrich von Weizsaecker, one of the last surviving witnesses of this period, kindly agreed to give a comprehensive interview on the German nuclear programme and the responsibility of physicists. The interview is published here for the first time and forms the central part of this brochure. It is complemented by two statements by Edward Teller and two historical letters. The author, in preparing this compilation, had in mind to contribute towards science-historical discussion and to give younger colleagues a graphic idea of the conflict surrounding nuclear research.

    Full Text Available Adult Still's Disease was first described in 1971 by Bywaters in fourteen adult female patients who presented with symptoms indistinguishable from that of classic childhood Still's Disease (Bywaters, 1971. George Still in 1896 first recognized this triad of quotidian (daily fevers, evanescent rash, and arthritis in children with what later became known as juvenile inflammatory arthritis (Still, 1990. Adult Onset Still's Disease (AOSD is an inflammatory condition of unknown etiology characterized by an evanescent rash, quotidian fevers, and arthralgias. Numerous infectious agents have been associated with its presentation. This case is to our knowledge the first presentation of AOSD in the setting of Rocky Mountain Spotted Fever. Although numerous infectious agents have been suggested, the etiology of this disorder remains elusive. Nevertheless, infection may in fact play a role in triggering the onset of symptoms in those with this disorder. Our case presentation is, to our knowledge, the first case of Adult Onset Still's Disease associated with Rocky Mountain spotted fever (RMSF.

    The ``Complejo Científico, Cultural y Turístico Simón Bolívar'' (CCCTSB), located in Maracaibo, Venezuela, lodges the Simón Bolívar Planetarium and an 150 mm aperture, 2250 mm focal length Carl-Zeiss-Jena Coudè refractor telescope. In this work we discuss the schematics for the automatization project of this Telescope, the planned improvements, methodology, engines, micro-controllers, interfaces and the uptodate status of the project. This project is working on the first two levels of the automation pyramid, the sensor -- actuator level and the control or Plant floor level. The Process control level correspond to the software related section. This mean that this project work immediately with the electrical, electronic and mechanical stuffs, and with the assembler micro controller language. All the pc related stuff, like GUI (Graphic user interfaces), remote control, Grid database, and others, correspond to the next two automation pyramid levels. The idea is that little human intervention will be required to manipulate the telescope, only giving a pair of coordinates to ubicate and follow an object on the sky. A set of three servomotors, coupling it with the telescope with a gear box, are going to manipulate right ascension, declination and focus movement. For the dome rotation, a three phase induction motor will be used. For dome aperture/closure it is suggested a DC motor powered with solar panels. All those actuators are controlled by a 8 bits micro-controller, which receive the coordinate imput, the signal from the position sensors and have the PID control algorithm. This algorithm is tuned based on the mathematical model of the telescope electro-mechanical instrumentation.

Although represented in only a handful of sites, the Still Bay is widespread geographically and, at certain localities, persisted over a substantial period of time. Many studies have focused on tracing the temporal range and geographic reach of the Still Bay, as well as inferring degrees of early modern human demographic connectedness from these parameters. Variation within the Still Bay, relative to the accuracy with which it can be identified, has received considerably less attention. However, demographic models based on the spread of the Still Bay in space and time hinge on the reliability with which it can be recognized in the archaeological record. Here we document patterns of bifacial point shape and size variation in some key Still Bay assemblages, and analyse these patterns using the statistical shape analysis tools of geometric morphometrics. Morphological variation appears to be geographically structured and is driven by the spatial separation between north-eastern and south-western clusters of sites. We argue that allometric variation is labile and reflects environmentally driven differences in point reduction, whereas shape differences unrelated to size more closely reflect technological and cultural fragmentation. Our results suggest that the biogeographic structure of Middle Stone Age populations was complex during the period associated with the Still Bay, and provide little support for heightened levels of cultural interconnectedness between distantly separated groups at this time. We briefly discuss the implications of our findings for tracing classic techno-traditions in the Middle Stone Age record of southern Africa, and for inferring underpinning population dynamics from these patterns.

    In this paper we present a novel method for multilingual artificial text extraction from still images. We propose a lexicon independent, block based technique that employs a combination of spatial transforms, texture, edge and, gradient based operations to detect unconstrained textual regions from still images. Finally, some morphological and geometrical constraints are applied for fine localization of textual content. The proposed method was evaluated on two standard and three custom developed datasets comprising a wide variety of images with artificial text occurrences in five different languages namely English, Urdu, Arabic, Chinese and Hindi.

    Full Text Available The article analyses the public-elucidative activity of theorist, co-operator and economist Carl Koberskyi and his influence on the development of financial-economical and co-operative education. This figure occupies an important place in the history of education and economy, due to his zealous public position and research of history of co-operative schooling. As practice testifies, research of Carl Koberskyi’s activity is described mostly either from the point of view of history or pedagogic. Our aim is to characterize the activity of the scientist and his economic ideas from the point of view of economics and to define their value for finance-economics and co-operative education. Carl Koberskyi’s active propagandist and organizational activity influenced the development of rural culture, distribution of co-operative motion, trade, banking and development of enterprise greatly. Weighty stage of economic and public establishment of western Ukraine took place in the after-war time, when the necessity of proceeding in economies and studies of professional specialists appeared in rural districts. Intelligent workers of the region strived to involve the peasantry into economic self-organization. At that time teachers considered trade education as a factor of social development and independence. Co-operative schooling began to be formed in the conditions of hard prohibitions and oppressions. Various public organizations, associations and unions that assisted the formation of national consciousness of population were quite widespread. Carl Koberskyi’s labour activity and his place in the co-operatively-economic sphere require further deep research, which will enable to improve the management of educational establishments and to develop finance-economics and co-operative education more effectively. Today, in the time of market relations development, Carl Koberskyi’s ideas of educationally-economic inheritance acquire special actuality, as they

  9. A solar still desalination system with enhanced productivity

    Ayoub, George M.

    2014-07-10

    Abstract: Increasing the productivity of solar stills has been the focus of intensive research. Many introduced developments, however, require complex components and entail notable increases in cost and land requirements. Developing a compact, productive, and easy-to-operate system is a main challenge. This paper describes a sustainable modification of the solar still that significantly enhances its productivity without forsaking its basic features. A simple amendment in the form of a slowly rotating drum is introduced allowing the formation of thin water films that evaporate rapidly and are continually renewed. The performance of this system was compared against a control without the introduced drum. Throughout the experiment, the new system gave considerably higher yield than the control with an average increase in daily productivity of 200%. Moreover, during sunshine hours, the increase in yield could surpass 6–8 times that of the control. Important parameters such as ease of handling, material availability, efficacy, low cost, safe water quality, and space conservation are maintained. One side-benefit of this design is solving stagnation problems that usually develop in conventional stills. The new simple modification in this study presents a cost-effective and efficient design to solar stills especially in areas with abundant sunshine.

  14. If formal CME is ineffective, why do physicians still participate?

    McLeod, P J; McLeod, A H

    2004-03-01

    Formal or traditional CME can be criticized because organizers often ignore adult learning principles when designing courses. Critics also suggest that formal CME courses have limited impact on attendees' behaviors and practices. The authors agree that attention must be paid to pedagogic principles to assure success of educational courses, but feel that the extant negative evidence related to the impact of formal CME is narrow in scope and of inadequate strength to seriously damn formal approaches. Survey responses were received from 853 practicing physicians who say they still regularly attend formal CME courses. They are motivated to attend to satisfy specific professional needs and for personal reasons. Formal CME is still popular despite what its critics say. The authors are convinced that attention to physicians' perceived needs, effective use of social marketing strategies, and adherence to adult learning principles can assure successful delivery of CME and that formal CME is a useful complement to physician-driven informal CME.

    Full Text Available Introduction. Diagnosing death represents an activity that carries a great deal of public responsibility for medical professionals and is continually exposed to the control of citizens and media. Although this is a taboo subject in medical circles, unfortunately in medical practice there are situations when the physician issues a death diagnosis form without even examining the person or for an already buried person. Such physician’s action is impermissible and it leads to the possibility of professional and criminal law punishment. Case Outline. By giving examples from practice, we wish to point out the need for exceptional caution when confirming and diagnosing death in order to diagnose the true, i.e. rule out apparent death and consequently avoid the mistake of declaring dead someone still alive. Conclusion. When confirming and declaring death, exceptional caution of the physician is necessary so as not to declare dead someone still alive!

    As the autumn gradually goes by, comments and reviews of the summer period films began to flourish. Positive ones give preference to Hollywood blockbusters such as Harry Porter, The Bourn Ultimatum and some others, negative comments, being unanimous and quantitative, target the Chinese-made films as generally secondary, less dramatic and boring. (Kilday,2007) The latter comments, though not totally correct, still sounds reasonable. Take the summer period box office for example, the total ticket office in North America is 4.3 billion dollars while it is 1 billion RMB in mainland China among which the imported films take up almost half. (Bai Qing,2007)Facing such a sharp contrast, we can do nothing but admit objectively that Chinese film industry still has a long way to go.

    Inadequate pain management but also inappropriate use of analgesics in early infancy has negative effects on neurodevelopmental outcome. As a consequence, neonatal pain management is still in search for the Holy Grail. At best, effective pain management is based on prevention, assessment, and treatment followed by a re-assessment of the pain to determine if additional treatment is still necessary. Unfortunately, epidemiological observations suggest that neonates are undergoing painful procedures very frequently, unveiling the need for effective preventive, non-pharmacological strategies. In addition, assessment is still based on validated, multimodal, but subjective pain assessment tools. Finally, in neonatal intensive care units, there is a shift in clinical practices (e.g., shorter intubation and ventilation), and this necessitates the development and validation of new pharmacological treatment modalities. To illustrate this, a shift in the use of opioids to paracetamol has occurred and short-acting agents (remifentanil, propofol) are more commonly administered to neonates. In addition to these new modalities and as part of a more advanced approach of the developmental pharmacology of analgesics, pharmacogenetics also emerged as a tool for precision medicine in neonates. To assure further improvement of neonatal pain management the integration of pharmacogenetics with the usual covariates like weight, age and/or disease characteristics is needed. PMID:27087155

    Full Text Available Water with large velocities can cause considerable damage to channels whose beds are composed of natural earth materials. Several stilling basins and energy dissipating devices have been designed in conjunction with spillways and outlet works to avoid damages in canals’ structures. In addition, lots of experimental and traditional mathematical numerical works have been performed to profoundly investigate the accurate design of these stilling basins and energy dissipaters. The current study is aimed toward introducing the artificial intelligence technique as new modeling tool in the prediction of the accurate design of stilling basins. Specifically, artificial neural networks (ANNs are utilized in the current study in conjunction with experimental data to predict the length of the hydraulic jumps occurred in spillways and consequently the stilling basin dimensions can be designed for adequate energy dissipation. The current study showed, in a detailed fashion, the development process of different ANN models to accurately predict the hydraulic jump lengths acquired from different experimental studies. The results obtained from implementing these models showed that ANN technique was very successful in simulating the hydraulic jump characteristics occurred in stilling basins. Therefore, it can be safely utilized in the design of these basins as ANN involves minimum computational and financial efforts and requirements compared with experimental work and traditional numerical techniques such as finite difference or finite elements.

  6. Experimental investigation on a coupled solar still under desert climatic conditions

    International Nuclear Information System (INIS)

    Distillation of water is energy intensive, and the use of solar energy for this purpose has been quite well developed and applied in many places. The performance of a simple basin greenhouse-type solar still coupled to a flat plate collector is experimentally investigated. The Saharan sites of Algeria enjoys bright sunshine and dry weather during most part of year. The objective of the work is to improve the performances of a simple single basin solar still, we test the distillation system in winter, under desert climatic conditions, to improve the quality and increase the quantity of distilled water, by using a solar collector for increasing the brine temperature, enhancing the evaporation process of a simple solar still and improving distillate collection process. Experiments have been conducted in Adrar, Algerian desert town (27 degree 18' N, latitude, 0 degree 17' W longitude). The daily still productivity in winter period varies from 4.5 l/m2/day to 5.3 l/m2/day with variation of water level from 1.5 cm to 3.5 cm. (Author)

    Science.gov (United States)

    Bartosch, Ulrich

    2014-01-01

    The intention of this article is to show the suitability of "Weltinnenpolitik" (world domestic policy) as an analytic and programmatic view on contemporary policy. A full reconstruction or comparison of Carl Friedrich von Weizsäcker's concept is not at the focus. As mentioned in other contributions to this volume, Weizsäcker did not refer to the disciplinary discourses in detail. His approach is particularly 'unique' since he set about in 1963 to study the conditions of peace in a very general way. By doing so, he was able to circumscribe the conditions of peace realistically: those valid for us today and apparently also in the future. Weizsäcker probably did underestimate the complexity of the transformation to sustainable politics for preventing climate change. Vice versa one should hope that we today do not discount the prevention of atomic war as a sine qua non for sustainable climate-saving policy. Both could mark the quintessential conditions for peace.

Questions remain regarding the underlying pathophysiology and etiology of AOSD. Pathognomonic diagnostic tests and reliable biomarkers remain undiscovered. Over the past decade, important progress has been made. Diagnostic criteria employing glycosylated ferritin have improved specificity. More important, novel biologic therapies have offered important clues to AOSD's underlying pathophysiology. Cytokine-specific biologic therapies have been instrumental in providing more effective treatment for disease refractory to conventional treatment. While IL-1 therapy has demonstrated efficacy in refractory disease, novel therapies targeting IL-6 and IL-18 show great promise and are currently under investigation.

    We report that even under the heated condition, the conformation and activity of a protein can be hoarded in a functionalized nanoporous support via non-covalent interaction, although the hoarded protein was not exhibiting the full protein activity, the protein released subsequently still maintained its native conformation and activity. Glucose oxidase (GOX) was spontaneously and largely entrapped in aminopropyl-functionalized mesoporous silica (NH2-FMS) at 20 oC via a dominant electrostatic interaction. Although FMS-GOX displayed 45% activity of the free enzyme in solution, the GOX released from FMS exhibited its 100% activity prior to the entrapment. Surprisingly, the released GOX from FMS still maintained 89% of its initial activity prior to the entrapment after FMS-GOX was incubated at 60 oC for 1 h prior to release, while the free GOX in solution lost nearly all activity under the same incubation. Intrinsic fluorescence emission of GOX and native electrophoresis demonstrated that the heating resulted in significant conformational changes and oligomeric structures of the free GOX, but FMS efficiently maintained the thermal stability of GOX therein and resisted the thermal denaturation and oligomeric aggregation.

    The luminosity of Carl Friedrich von Weizsäcker's holistic thinking in the former German Democratic Republic (DDR) is reviewed. Broad-minded academics sought, in accordance with the modern paradigm of self-organization, beyond the ideological template for ways out of the dead end of incrustations of society and innovation blockages under the constraints of a dictatorship. Right after the fall of the wall, Weizsäcker willingly backed a "community of free researchers for self-organization" (Freie Forschungsgemeinschaft Selbstorganisation, FFGSO). This group, conceived as a nonpartisan "think tank" of civil activism, is also discussed. At a number of its meetings Weizsäcker debated the dangers of ideologically influenced science. The effectiveness of the dual leadership at his own Starnberg Institute, for instance, was stymied by the tensions arisen out of such conflicting aims. Against the voluntaristic anticipations of the mainstream in sociology, precisely that system proved to be more viable that was meant to be overcome: faulty and purportedly futureless capitalism. Weizsäcker repudiated social prognoses made in the absence of rules for their falsification resp. verification. Weizsäcker acted as a leading figure at the FFGSO's Potsdam conference, opened on 30 Mar. 1990, on the "DDR--and afterwards?". Its intention was in order to trigger a nationwide discussion of scientific scenarios in designing German unification in the face of gross practical disparities between East and West Germany. The Trust Agency inspired by the FFGSO at the Round Table between opposition and old government was supposed to transfer the national public property "Volkseigentum" of the DDR into private property of the East German citizens, to enable them to realize a role as subject through self-organization. At the group's request, Weizsäcker mediated the readiness by the Lutheran World Federation to assume the role of ombudsman in anticipation of conflicts of interest within the

    Tonso's commentary on Sinnes and Løken's paper links what they found to empirical research done in science and engineering career settings. Sinnes and Løken's findings are a welcome addition to a literature dedicated to pointing out, yet again, some of the reasons we have made so little progress reversing gender inequities in the last 35 years. Their critique of Project Lily adds to what we know about initiatives that fail to grasp the futility of depending on either changing women so they become a better fit in STEM fields (few women exist of this sort) or highlighting those aspects of STEM fields perceived as attractive to underrepresented communities (the masculinized downside will still exist). Sinnes and Løken thus join a growing literature calling for cultural change in STEM disciplines and careers and providing a model feminist critique that other scholars can use to challenge similar initiatives.

    Acute shortage of good, clean drinking water is a major problem for most developing countries of the world. In most cases, ponds, streams, wells and rivers are often polluted that they are unsafe for direct use as drinking water >.Often water sources are brackish and or contain harmful bacteria. Therefore cannot be used for drinking .In addition there are many coastal locations where sea water is abundant but potable water is not available. Solar distillation is one of the important methods of utilizing solar energy for the supply of potable water to small communities where natural supply of fresh water is inadequate or of poor quality .In this direction an experimental performance analysis was carried out on a single basin still compared with FPC coupled one. Test were carried out for different water samples namely borewell water, sea water, river water for a water depth of 20 mm

    Vesicoureteric reflux (VUR) is the most common congenital anomaly of the uropoetic system. The gold standard for its diagnosis is the voiding cystourethrogram. Sonographic cystourethrography is an alternative method for reflux detection, but it is still not used routinely. Static scintigraphy enables us to diagnose renal scarring reflux nephropathy (RN). While congenital RN is a result of prenatal kidney injury, acquired RN results from pyelonephritis-induced renal damage.Risk factors for RN include VUR, recurrent APN, lower urinary tract dysfunction and delay in treatment of febrile urinary tract infection. Management of children after APN with VUR consists of antibiotic prophylaxy, surgery or surveillance only. The conclusions of performed studies are controversial, thus unified guidelines for the management of patients with VUR are not available. PMID:27256146

  4. Parameters affecting the performance of a low cost solar still

    International Nuclear Information System (INIS)

    Highlights: • The triangular solar still is designed using cheap and durable materials. • The initial water depth has an inverse relationship with the production. • The water productivity is nearly proportional to the solar radiation. • The water quality parameters are within the accepted ranges of drinking water. - Abstract: This study aims at developing a low cost technique to be used in rural and coastal areas for converting saline water into potable water using solar energy. A triangular solar still (TrSS) was, therefore, designed and developed with cheap, lightweight, local and available materials. A number of field experiments were carried out to evaluate the effects of solar radiation intensity, ambient air temperature and the initial water depth on the daily water production of the TrSS. A time lag of about and hour between the hourly peaks of solar radiation and water production is observed. Finally, a few essential relationships were attained, e.g. between the daily production and the initial water depth, between the daily production and daily solar radiation, and between the daily production and the average ambient temperature. The effect of the initial water depth in the basin on the daily water productivity was evaluated by varying the water depths (1.5, 2.5 and 5 cm) with the climatic condition of Malaysia and an inverse proportional relationship was revealed between them. However, the daily water productivity is nearly proportional to the daily solar radiation. In addition, some important water quality parameters were tested in the laboratory to evaluate the distillate quality and were then compared with the drinking water standards

    Full Text Available Context: In the present era of stapedotomy, there is an inevitable role for laser. But the conventional technique with manual burr still has its own merits in various settings such as usage in resource poor setting in developing countries and avoidance of laser hazards. AIMS: To evaluate the audiometric outcomes after manual stapedotomy. Settings and Design: The present study was retrospective record-based study. Patients who have been diagnosed otosclerosis and those who were not willing for surgery with laser, but gave consent for manual stapedotomy were included for the study. Materials and Methods: Preoperatively, and at each subsequent post-operative follow-up visits, patients were required to undergo a pure-tone audiogram. The air-bone gaps at the end of 6 months were used for final analysis. Statistical Analysis Used: Data was analyzed with using Statistical Package for Social Sciences (SPSS version 12 (Chicago, IL, USA. Descriptive frequency distributions, mean, standard deviation of audiometric data were calculated. The paired t test was done to see the improvement in the air bone gap post-operatively. Results: The mean age of presentation is 32.2 years. Overall, the male:female ratio was found to be 1:1.2. Post-operative air bone closure to 15 decibels was obtained in 80% of patients. There was no significant correlation between the pre-operative hearing loss and post-operative gain, age, and gender of distribution of focus. Conclusions: The post-operative hearing after stapedotomy has been remarkable in all the patients even with manual burr. There were no major vestibular complications in any of these patients. The study has shown that the significant post-operative hearing results can be still achieved with meticulous surgery by an experienced surgeon with manual burr in the present laser era.

  6. Russian crude-oil production and export still increasing

    International Nuclear Information System (INIS)

    Russian crude-oil production is still increasing. In 2000 the annual production 6.48 mb/d was about 6% higher than a year before. In 2001 the production is expected to rise near the level 7 mb/d, so the increase in production volume is fast. However, the production is still far away from the maximum level of the former Soviet Union, 12 mb/d. At the moment Russia is the second largest oil producer right after Saudi Arabia. The increase in production is based on intensified use of old oil fields caused by improved technology. The oil export of Russia far abroad in 2000 was 2.5 mb/d and near abroad into FSU countries only about 180 000 b/d. The recent export of crude-oil has been near the maximum export capacity corresponding to 2.7 mb/d. About 61 million tons of oil products were exported in 2000, and even the export of oil products is increasing. Most of this was gas oil and heavy fuel oil, but also the export of gasoline was significant. The export of oil and oil products is mainly based on shipments, but also the share of train transport is high. Nearly all the crude oil is transported west either by ships or via pipelines. The share of railway transport is only few percents. Russia will continue its own oil pumping policy despite of the appeals of OPEC for reduction of oil production. Opinion in Russia is that if the increase of production and export serves the interests of Russia, it will also be carried out. The target value for crude oil for 2002 is 22 USD per barrel. The Russian crude oil production is estimated to grow up to 7.4 - 8.4 mb/d by the year 2010

    2013-04-01

    The original histological investigation that forms the basis of our present understanding of tooth movement was carried out on dogs by the Swedish dentist Carl Sandstedt at the Karolinska Institute, Stockholm. His findings were published in 1901 as a monograph in Swedish, and shortly after his death in 1904, as three articles in German entitled 'Einige Beiträge zur Theorie der Zahnregulierung'. Sandstedt observed that the bone was deposited on the alveolar wall of the tension side with both heavy and light forces, new bone spicules following the orientation of the periodontal fibres. On the pressure side, with light forces, osteoclasts resorbed the surface of the alveolar bone, but heavy forces compressed the periodontal ligament resulting in hyalinization--the formation of localized cell-free areas. At these sites, bone removal resulted from undermining resorption by osteoclasts from adjacent marrow spaces. He also observed root resorption and commented on the centre of rotation of the teeth. No English version of Sandstedt's research has ever been published, and in view of its importance, one of us (DB) has translated his three articles from the original German. The aim was to persuade an orthodontic journal to publish the articles in full--however, weighing-in at 21,000 words, the impracticality of this plan soon became clear. We concluded that excerpts from the text plus commentary would be the most practical solution. Where possible and without materially changing the intended meaning, we have translated the German text into something resembling contemporary English, accompanied by the original 16 figures.

    2005-04-01

    Full Text Available Parmi les nombreux problèmes que pose l’ouvrage de Carl Schmitt Le Léviathan dans la doctrine de l’État de Thomas Hobbes, il en est un, majeur, qui concerne l’utilisation de la « mythologie politique » pour expliquer la réalité ou les doctrines politiques. Il y a là, à n’en pas douter, l’expression de l’un des versants de l’irrationalisme de Schmitt. La thèse de l’auteur est très claire : parce que Hobbes ne possédait aucun « sens mythologique », il s’est trompé de monstre biblique, appelant Leviathan son traité consacré au pouvoir d’État, alors qu’il aurait dû l’appeler plus adéquatement Behemoth, manquant du coup la Meeresbild caractérisant l’Angleterre de son temps. La thèse peut paraître séduisante, elle s’appuie néanmoins sur un présupposé fort contestable, car Hobbes ne vise nullement à créer des mythes. Il s’agit donc d’interroger la théorisation hobbesienne de la piraterie, d’une part, et de la dissidence religieuse « sauvage », d’autre part, afin de montrer que le choix par Hobbes des monstres du Livre de Job est un choix rationnellement assumé.

    Full Text Available The modulation of the Compatibility Effect (CE according to the compatibility of the previous trial (Sequential Compatibility Effect, SCE in three types of attentional tasks is explored. The flankers and spatial Stroop tasks have different degrees of cognitive complexity. In all three tasks it is analyzed whether the SCE varies when the stimuli in consecutive trials are exactly the same (pure replicas or not. The data, collected from three independent samples (total N = 1.159, show the CE in the three tasks. However, SCE only shows up in the spatial Stroop task. The effect is smaller albeit still significant when the pure replica trials are removed, a result inconsistent with those of Mayr et al. (2003 and Hommel (1998 but consistent with the Conflict Theory (Botvinick et al., 2001. Furthermore, we also discuss the importance of cognitive complexity in relation to the perspective of Botvinick et al. (2004. From this point of view more complexity should be reflected in a greater presence of cognitive conflict, and therefore a higher SCE.

    Several issues dominated the 36th Red Deer Seminar of the propane industry, among them changes to the Alberta fuel tax collection system, propane and automobile emissions and industry self-management. With regard to changes to the Alberta fuel tax collection system, details were provided on how the system, coming into effect on January 1, 1997, will impact on producers, distributors and retailers. In terms of automobile emissions, it was said that propane has lagged behind gasoline in technological development, hence propane no longer has advantages in emissions. It was noted, however, that with equivalent technology propane can still meet ultra-low emission standards. Regarding industry self-management, it was stressed that self-management did not mean deregulation since government retains policy, regulation and standard setting. It means a new partnership arrangement in which industry delivers services formerly provided by government. In this spirit of cooperation, it was announced that effective September 1996, administration of the auto propane vehicle conversion program will be transferred to the PGAC under the name of Alberta Propane Vehicle Administration Organization. 3 figs.

    2015-01-01

    Full Text Available Background: Human brucellosis is a disease with protean clinical manifestations. Despite many awareness programmes, it is still missed or wrongly diagnosed. This leads to chronic morbidity leading to misery and loss of working days. Aim and Objectives: To assess the microbiological, clinical and epidemiological aspects of human brucellosis. Materials and Methods: Patients with positive brucella screening test constituted the study material. A detailed laboratory, clinical, epidemiological study along with response to the treatment was analyzed. Results: Seroprevalence of brucellosis was found to be 1.75%. Brucellosis was clinically diagnosed in only 12.73% of cases. Fever, joint pain and low backache were the commonest symptoms. Close contact with animals and raw milk ingestion were the major sources of infection. Knowledge regarding brucellosis and its prevention was lacking in patients. Brucellosis was not considered as one of the differential diagnosis by the treating physicians. Conclusion: Brucellosis should be considered as one of the differential diagnosis in cases presenting with fever, low backache, arthritis and arthralgia. Laboratories should screen all the serum samples for brucella agglutinins by Rose Bengal Plate Test. Awareness regarding the prevention of brucellosis in the general population and regarding the existence of the disease among the doctors practicing in rural areas is needed

  16. US firms still restructuring, cutting costs under oil price uncertainty

    International Nuclear Information System (INIS)

    Despite more than a decade of downsizing, continuing uncertainty in oil markets is forcing US petroleum companies into another round of cutting and restructuring operations. Wellhead gas prices in the US, although still volatile, in the past 2 years have risen to levels adequate to allow profits for most producers in that sector. Higher gas reserves valuations have strengthened producers' overall balance sheets. But the slide in oil prices from the middle of fourth quarter 1993 until the recent upswing the past month has withered producers' financial performances and reserves values. With little prospect of significantly higher oil prices anytime soon, US companies feel they have little choice but to continue pressing cost cutting moves in order to sustain profits in the near term while at the same time earnings a higher return on investment in the long term. Petroleum company executives are overlooking almost no operating or investment strategy thought capable of bolstering the bottom line. Because no two US oil and gas companies are alike, each profit protection plan is a unique mix of similar solutions. Oil and gas production companies most often try to lower operating costs by vigorously selling noncore properties or business units and reducing staff. The paper discusses measures taken by oil and gas companies to lower costs

    We report continued Hubble Space Telescope (HST) ultraviolet spectra and ground-based optical photometry and spectroscopy of GW Librae eight years after its largest known dwarf nova outburst in 2007. This represents the longest cooling timescale measured for any dwarf nova. The spectra reveal that the white dwarf still remains about 3000 K hotter than its quiescent value. Both ultraviolet and optical light curves show a short period of 364-373 s, similar to one of the non-radial pulsation periods present for years prior to the outburst, and with a similar large UV/optical amplitude ratio. A large modulation at a period of 2 h (also similar to that observed prior to outburst) is present in the optical data preceding and during the HST observations, but the satellite observation intervals did not cover the peaks of the optical modulation so it is not possible to determine its corresponding UV amplitude. The similarity of the short and long periods to quiescent values implies the pulsating, fast spinning white d...

  18. Does Canada still need a national oil company

    International Nuclear Information System (INIS)

    This paper reports that Petro-Canada was described by the government at the time of its establishment in 1975 as a most important element in the planning to secure Canada's long-term energy requirements. Through it, Canadians were to obtain their supplies at reasonable prices, and were to participate directly in the wealth resulting from their development. Nine years later, a government dedicated to privatizing the company came to power. It lost no time in instructing the company to behave as if it were in the private sector. More recently, it has put legislation before parliament that would cause the company's shares to be made available to the public. A decision to privatize Petro-Canada does not, however, mean that some of the purposes for which it was set up are still not valid or that there are not other public interests that a Canadian national oil company could serve. Indeed, certain of the energy provisions of the Canada-U.S. Free Trade Agreement may have increased its importance as a potential policy arm. These include limitations on export controls and on the taxation of exports, and an undertaking to extend equality of treatment to US companies

  19. Refineries: better fundamentals, but good margins are still elusive

    International Nuclear Information System (INIS)

    Utilization rates for primary distillation capacity in OECD Europe have risen from 59% to 92% over the past ten years. Improvements in utilization rates have occurred in North America, Asia and Australasia over the same period too. In non-OECD Europe, however, utilization has declined from 85% to 54%. Worldwide, utilization has increased from 72% to 82%. Refining margins, have developed less satisfactorily, though, and opinions differ on future prospects. The debate centres on how quickly the still significant surplus capacity outside western Europe, and moth-balled distillation units within Europe, are brought back on stream. The existence of this idle capacity limits price increases. Although rising demand in Asia has contributed to western European utilization while Kuwaiti refineries have been out of action, their restoration is likely to reduce Asian demand for European refined products. In addition, western European margins are likely to be affected by the huge volume of refinery construction in Asian countries. In the USA, refiners are experiencing difficulties in producing gasolines which conform to new government specifications. (2 figures, 2 tables) (UK)

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Current recommendations advise that stavudine be phased out of use. The logistics and cost of switching are significant, and the World Health Organization has forecast that 1.55 million people will still be on stavudine-based antiretroviral therapy by the end of 2012. Stavudine is co-formulated in many countries, is very cheap and effective, and is well tolerated in initial therapy. However, the 40 mg BD dose was associated with considerable long-term toxicity. Several studies suggest that half the original recommended dose has excellent antiviral efficacy with significantly reduced metabolic side-effects. Despite generic tenofovir now being cheaper than zidovudine, tenofovir consumes the majority of adult antiretroviral programme medication budgets in programmes in Africa, where it is used in first-line therapy. Abacavir is far more expensive than zidovudine or tenofovir, and is a major cost driver in paediatric programmes with access to abacavir-based first-line treatment. Low-dose stavudine may offer the only cheaper (and possibly as effective and safe alternative to programmes grappling with limited financial resources.

    I am 40 years old but my average age is 4. Who am I? The answer is the CERN nursery school, located near Gate A on the Meyrin site. This year's traditional end-of-year party on 24 June was a lot more lively than usual. To mark the school's fortieth birthday in style, the teachers dressed up in pretty, floating costumes, a clown on stilts was in attendance, to the delight of a fascinated crowd of children, and balloons were released into the sky. Dozens of balloons were released into the sky to mark the CERN nursery school's 40th Anniversary.Standing on stilts and performing a juggling act, the clown was the highlight of the evening. In 1965, when it was created on the initiative of a group of parents, the nursery school consisted of a single class that was open in the mornings only and was held in a room located outside the CERN site. The Staff Association took up the reins right from the start and is still running the school today. The school went from strength to strength. "Even at the beginning, there was...

  2. Carl Jung's interpretation of Wolfgang Pauli's dreams: The Bailey Island, Maine, and New York City seminars of 1936 and 1937

    Science.gov (United States)

    Brown, Richard Paul

    This dissertation reviewed the development of Jung's dream theory and addresses the question as to whether or not Jung was influenced by the dreams of the Nobel Prize winning physicist, Wolfgang Pauli. Jung provided an extensive analysis of Pauli's dreams, which are contained in the lightly edited, unpublished transcripts of lectures delivered in 1936 and 1937. An archival and hermeneutic analysis of the texts reveals a staged process of individuation that Jung related to in many ways because of the parallels to his own personal journey toward individuation. A chronological history of the development of Jung's dream theory is presented, followed by a picture of the relationship between Jung and Pauli. Thereafter, a detailed summary of the seminar transcripts, one given on Bailey Island, Maine, and the other in New York City the following year, is offered with hermeneutic commentary. An analysis of the seminars found that Pauli's dreams did, in part, support Jung's theory. Specifically, while Jung was unable to meet the scientific demands for clear empirical evidence of his dream theory, he did offer his professional and non-professional audiences with a slightly less rigorous example of his dream theory in action, demonstrating that the process shared similarities across peoples, time, and cultures. Additionally, in Pauli he found a superior mind that had gone through the process of individuation in accordance with his theory and his own experience. During the course of research, reference to a document was found in the correspondence in the Jungian Archives in Zurich. This document entitled, "FAREWELL SPEECH, Given by Dr. C. G. Jung on the Occasion of a Dinner Given in His Honor by the Analytical Psychology Club of New York City October 26, 1937" and other related documents were subsequently uncovered in the sub-basement of the Kristine Mann Library in New York City. A synopsis of the discovery and description of the papers contained in the file are discussed in

    The power industry should jointly address questions about FGD water treatment and share the lessons it has learned so far. The article describes a scheme developed by CH2M Hill to treat FGD wastewater and remove heavy metals. The process desaturates the waste water of sulfates and removes the bulk of the insoluble suspended solids prior to tertiary treatment of heavy metals using a chemical/physical treatment process. Additional treatment could be provided (for example, anoxic biological treatment) for selenium, nitrates and organics. 2 figs.

    Full Text Available An experimental work was reported to estimate the increase in distillate yield for a compound parabolic concentrator-concentric tubular solar still (CPC-CTSS. The CPC dramatically increases the heating of the saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a large quantity of distillate yield. A rectangular basin of dimension 2 m × 0.025 m × 0.02 m was fabricated of copper and was placed at the focus of the CPC. This basin is covered by two cylindrical glass tubes of length 2 m with two different diameters of 0.02 m and 0.03 m. The experimental study was operated with two modes: without and with air flow between inner and outer tubes. The rate of air flow was fixed throughout the experiment at 4.5 m/s. On the basis of performance results, the water collection rate was 1445 ml/day without air flow and 2020 ml/day with air flow and the efficiencies were 16.2% and 18.9%, respectively.Findings:The experimental study was operated with two modes: without and with air flow between inner and outer tubes.

The model assumes that the teacher wishes to choose actions that are as appropriate as possible to the situation and goals of teaching. Knowledge and emotional variables influence the process. (SLD)

  6. Plant Peroxisome Multiplication: Highly Regulated and Still Enigmatic

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Plant peroxisomes play a key role in numerous physiological processes and are able to adapt to environmental changes by altering their content, morphology, and abundance. Peroxisomes can multiply through elongation, constriction, and fission; this process requires the action of conserved, as well as species-specific proteins. Genetic and morphological analyses have been used with the model plant Arabidopsis thaliana to determine at the mechanistic level how plant peroxisomes increase their abundance. The five-member PEX11 family promotes early steps of peroxisome multiplication with an unknown mechanism and some subfamily specificities. The dynamin-related protein (DRP)3 subfamily of dynaminrelated large guanosine triphosphatases mediates late steps of both peroxisomal and mitochondrial multiplication. New genetic and biochemical tools will be needed to identify additional, especially plant-specific, constituents of the peroxisome multiplication pathways.

    2015-01-01

    This paper proposes a method called rotate intra block copy, which extends the intra block copy technique by making the block matching process invariant to rotation. HEVC intra prediction plus rotate intra block copy gives an average of 20% reduction in residual energy (i.e. prediction error) compared to HEVC intra prediction plus intra block copy. As the motion vector correlation in rotate intra block copy is different from the intra block copy, a new method of motion vector coding is pre...

  10. Experiments in Physical Chemistry, Sixth Edition (by David P. Shoemaker, Carl W. Garland, and Joseph W. Nibler)

    Feigerle, Charles S.

    1997-05-01

    McGraw-Hill: New York, 1996. xii + 778 pp. ISBN 0-07-057074-4. Experiments in Physical Chemistry has long been one of the best textbooks available for undergraduate courses in physical chemistry laboratory. The present edition follows a similar format as previous editions, consisting of (i) a series of introductory sections dealing with common aspects of all experiments, such as recording of data, report writing, data and error analysis, and the use of computer software to aide in these, (ii) 48 experiments spanning 12 fundamental areas, and (iii) a series of resource chapters providing an introduction to electronics, instruments, techniques, and procedures commonly utilized in the performance of experiments in physical chemistry. Some needed changes have been incorporated in this edition, most notably the addition of sections that recognize the increased role of computers in modern experimentation. In particular, the section on computer software has been expanded and moved ahead of the experiments. The use of word processing, spreadsheets, and symbolic mathematics programs is emphasized, with examples using some of the most popular commercial programs. Three new experiments have been added and a fourth substantially modified. Each of the 44 other experiments has undergone some review and modernization, and a much-needed section on safety issues has been added to each. A resource chapter on computer interfacing, treating data types, programming languages and interfacing has been added. Examples are given for programming RS-232 communication and analog/digital interface boards using visual basic routines. I recommend this book be given serious consideration as a text for a one- or two-semester course in physical chemistry laboratory. The approach to experimentation in physical chemistry, the experiments, and the techniques that are described can form a solid basis for such a course. My one criticism is that the text offers only a limited number of laser

    2016-01-01

    There are still many questions that remain about the Moon. From concentric craters to lunar swirls, water vapor and lunar reverberations on impact, Foster collects it all for a fascinating tour that will illuminate the backyard observer's understanding of this easily viewed, yet also imperfectly understood, celestial object. Data from Apollo and a flotilla of unmanned Moon orbiters, crashers, and landers have all contributed to our understanding of the Moon, but these mysteries linger despite decades of research. When Project Apollo brought back lunar rocks and soil samples, it opened a new chapter of understanding Earth's lone natural satellite, a process that continues to this day, as old results are revisited and new techniques are used on existing samples. Topics such as the origin, evolution, structure and composition of the Moon, however, are still under debate. Lunar research is still an active field of study. New technologies make it possible to continue to learn. But even so, the Moon continues to h...

  13. Excellence - but still a long way to go

    International Nuclear Information System (INIS)

    In December of 1982, the Baltimore Gas and Electric Company began a concerted effort to pursue to INPO accreditation of five training program areas. With the accreditation of the Radiation Protection Technician and Chemistry Technician programs in December 1984, Calvert Cliffs is in the enviable position of having half of its programs accredited. The approach to accreditation was not unique, perhaps not even unusual, but it was well planned and well executed. It incorporated advice from other utilities and included firsthand experience on two accreditation team visits. The project's organization was structured to get the job done with minimal impact on the actual training being conducted concurrently. Finally, elements of the Quality Assurance Program's philosophy was used to document findings during the self-evaluation and track their associated corrective actions. With the unqualified support of management, improving the quality of training was easy. The accreditation process became a method to ensure improved performance and morale through effective training, not from the act of having been accredited, but rather by improving the deficiencies found during the self-evaluation. This benefit was immediately reflected in other programs as well, since the processes and standards used to develop training material, certify instructors or evaluate training effectiveness were used throughout all the training programs

    1991-01-01

    Rudolf Ludwig Carl Virchow (1821-1902) had been prosector at the Charité of Berlin, from 1846 to 1849. He had moved to Berlin in October 1839 for army surgeon training at the Pépinière, the Academy of Military Medicine. He had to choose that line of education, as it was free, for his parents were in no financial position to pay for ordinary university studies. On completion of theoretical classes, Easter 1843, he was delegated to Charité for an 18-months practical training programme. He worked in all compulsory clinical departments and, subsequently, took up service in the Prosector's Department then headed by Robert F. Froriep who guided and supported Virchow towards independent scientific activity. Virchow defended his doctoral thesis with good success in 1843. His application for the expected vacant office of Prosector was supported by Froriep before he left Berlin in 1846. The application was granted "ad interim", on May 11, 1846. His name became known very soon on account of his ambitious commitment. He also began to take a growing commitment to political change in Prussia in general, and change to the medical system in particular. He achieved discharge from military service in 1847, formally qualified for university lecturing, and was officially appointed as Prosector and lecturer. In the same year, 1847, he founded the "Archives" in cooperation with Benno H. E. Reinhardt. During an epidemic cholera outbreak in Berlin and an outbreak of petechial typhus in Upper Silesia, early 1848, he realised social root causes of disease and accused the Prussian government for negligence of its own citizens. He then joined the March struggles of 1848 out of his insight into the need for change of society. A weekly under the heading of "Die medicinische Reform" ("Reform in Medicine") was published under Virchow's editorship, from mid-1848 to mid-1849. Early 1849, his involvement on the premises of Charité in a leaflet campaign against planned mock elections in Prussia

    Scientists and laypeople agree on high ability as a defining feature of giftedness. Yet their views on gifted people's socioemotional characteristics diverge. Most studies find the gifted to be similar or slightly superior to average-ability persons in these domains (“harmony hypothesis”). However, subjective conceptions and media representations, most of which have focused on gifted children and youth, stress the socioemotional downsides of giftedness (“disharmony hypothesis”), affecting highly able individuals and those around them, thus hampering individual development. To date, most studies on gifted stereotypes have examined selective samples, mostly teachers. The present study is the first to provide representative data on conceptions of gifted individuals in general. A brief survey of 1029 German adults assessed quality and prevalence of stereotypes about gifted individuals, without an explicit focus on children and/or adolescents. Latent class analysis (LCA) revealed two conceptions of giftedness, with twice as many “disharmonious” than “harmonious” raters. Male gender, single parenthood, unemployment, higher income or negative attitudes toward the gifted predicted disharmonious ratings. However, effects were small, suggesting future studies look deeper into the processes of stereotype formation and maintenance. PMID:27047409

  17. CERI says lower power rates still in the future

    International Nuclear Information System (INIS)

    The impact that consumers will encounter with the convergence of Alberta's natural gas and electric utility industry were discussed. It will take a few years of infrastructure improvements before lower rates and improved efficiencies will be realized. Electricity prices in Alberta are expected to increase until the next generating capacity is connected to the provincial power grid. In addition, consumer prices are increasing because of the province's reliance on imports from British Columbia to meet peak demand. In August 2000 the province held a controversial auction of its generating capacity. The auction raised little more than $1 billion to the balancing pool, well short of the $4 billion target. Two major power facilities, the Genesee and Sheerness, failed to attract any bids at all. Despite this, the government accepted the results of the auction and will move forward with its retail restructuring program which calls for the competitive power market to be in place on January 1, 2001. The five major bidders who acquired the right to market about 4,249 megawatts of generating capacity from eight generating units in Alberta are EPCOR Utilities Inc., ENMAX Energy Corp., Enron Canada Power Corp., TransCanada PipeLines Ltd., and Engage Energy. The Alberta government is in the process of finalizing details of how the raised funds will be used to offset the impact of electricity rates

    Full Text Available This paper presents a comparative study to evaluate and compare Fortran with the two most popular programming languages Java and C++. Fortran has gone through major and minor extensions in the years 2003 and 2008. (1 How much have these extensions made Fortran comparable to Java and ++? (2 What are the differences and similarities, in supporting features like: Templates, object constructors and destructors, abstract data types and dynamic binding? These are the main questions we are trying to answer in this study. An object-oriented ray tracing application is implemented in these three languages to compare them. By using only one program we ensured there was only one set of requirements thus making the comparison homogeneous. Based on our literature survey this is the first study carried out to compare these languages by applying software metrics to the ray tracing application and comparing these results with the similarities and differences found in practice. We motivate the language implementers and compiler developers, by providing binary analysis and profiling of the application, to improve Fortran object handling and processing, and hence making it more prolific and general. This study facilitates and encourages the reader to further explore, study and use these languages more effectively and productively, especially Fortran.

  20. Without the science of intangibles, the earth is still flat

    Islam, M. R.

    2008-02-01

    The modern age, leading up to the Information age, has been dominated by Europe-centered science, often termed as the 'New Science'. Even though it is not readily recognized, the root of this New Science lies within Aristotle's theory of excluded middle and old Greek philosophy that confuses between ideal and real. These same principles, which is synonymous with the short-term approach (focusing on tangibles or taking Δt to 0), was supported by the Roman Catholic Church, which, in turn opposed the emergence of New Science. This dichotomy is not clear as the original science (as in process) has been divided into many branches, such as hard science, social science, theology, and others. Because this distinction is not clear, a scientist can be pro-science and pro-Church at the same time. This would explain why most scientists who are credited to have pioneered new science did not confront the fundamental dogmas of the Church. Galileo, for instance, never opposed the original dogma of Catholic church yet he drew the wrath of the church because he opposed the literal (tangible) meaning of the book that was being promoted as the holy book (bible literally means, The Book). In scientific sense, what Thomas Aquinas, the man credited to have revived Aristotelian logic (via Averröes's translation), was to Christianity what Newton was to New Science and Mathematics. Both of them based their syllogism on the first premise that was aphenomenal. It is no surprise that most of the New Scientists are 'believers' of Christianity. Greek philosophical notions of idea or form could not be verified or disproved by experiment, so outside of mathematics, the Greek philosophical approach was sloughed off in experimental science. The problem was that neither the Greek notions of idea and form, nor experimental science, revealed the truths of nature. Yet, those notions were dominant in New Science. Experimental studies had the advantage of helping to eliminate what was outrightly false

  5. VLA's Sharpened Vision Shows Details of Still-Forming Star

    Science.gov (United States)

    2001-01-01

    Using a new observing capability of the National Science Foundation's Very Large Array (VLA) radio telescope, astronomers have discovered a solar-system-sized disk of gas and dust feeding material onto a young star with 8 to 10 times the mass of the Sun. This is the first time an inner "accretion disk" has been seen around such a massive star. The VLA images also revealed the inner portion of an energetic outflow of material powered by the accretion disk. Artist's conception "Disks and outflows in young stars increase dramatically in mass and energy as the mass of the young star increases. We don't know if the same process is at work in all young stars or how the disks can both power an outflow that extends more than 15 light-years and also start the process of forming planets," said Debra Shepherd, of the National Radio Astronomy Observatory (NRAO) in Socorro, New Mexico. "By studying the birth of massive young stars, we're pushing the limits of our understanding and trying to learn if there are critical differences between the outflows from high and low mass young stars," she added Shepherd and Mark Claussen, also from the NRAO in Socorro, and Stan Kurtz of the National Autonomous University in Mexico, presented their findings today at the American Astronomical Society's meeting in San Diego, CA. The scientists made the discovery using the VLA connected by a newly- operational fiber-optic link to one of the radio-telescope antennas of the NSF's Very Long Baseline Array (VLBA), located at Pie Town, NM, 32 miles away from the VLA. Linking the VLA to the Pie Town antenna almost doubled the resolving power, or ability to see fine detail, available to the astronomers. "We could not have seen these structures without using the Pie Town antenna connected to the VLA," said Claussen. Work on the VLA-Pie Town fiber-optic link, financed by the NSF and Associated Universities, Inc., which operates NRAO for the NSF, began in late 1997. The linked facilities first were

  8. The Enemy is Still Below: The Global Diffusion of Submarines and Related Technology

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, K G

    2012-06-05

    The spread of submarines and related technology is an end product of globalization. Globalization is not a new story. By one estimate, our ancestors first crossed out of Africa roughly 80,000 years ago, and began the process that they now call globalization. With the dispersion of people around the world came the development of culture and civilization as well as the spread of ideas, goods, and technology. The process of globalization then is a long-standing one, not an innovation of the late 20th and early 21st centuries. Over the millennia, this process has been an uneven one. Globalization has often cuased great disruptions even to the societies that initiated various innovations in culture and civilization, including science and technology. Indeed, many cultures and civilizations have disappeared while some regions failed to advance as rapidly as others, so the process of globalization is not just one of continuing progress. Globalization in the current era seems to be penetrating the most remote corners of the world at a remarkable rate as a result of advances in science and technology, particularly information technology. The diffusion of science and technology is not necessarily a benign development. It could increase the potential for a global military industrial base that may have an adverse affect on world stability in the future. For example, the spread of key military capabilities, like submarines, could still have an impact, especially over the longer term, on the US capability to project power overseas.

  9. Improved crystal orientation and physical properties from single-shot XFEL stills

    International Nuclear Information System (INIS)

    X-ray free-electron laser crystallography relies on the collection of still-shot diffraction patterns. New methods are developed for optimal modeling of the crystals’ orientations and mosaic block properties. X-ray diffraction patterns from still crystals are inherently difficult to process because the crystal orientation is not uniquely determined by measuring the Bragg spot positions. Only one of the three rotational degrees of freedom is directly coupled to spot positions; the other two rotations move Bragg spots in and out of the reflecting condition but do not change the direction of the diffracted rays. This hinders the ability to recover accurate structure factors from experiments that are dependent on single-shot exposures, such as femtosecond diffract-and-destroy protocols at X-ray free-electron lasers (XFELs). Here, additional methods are introduced to optimally model the diffraction. The best orientation is obtained by requiring, for the brightest observed spots, that each reciprocal-lattice point be placed into the exact reflecting condition implied by Bragg’s law with a minimal rotation. This approach reduces the experimental uncertainties in noisy XFEL data, improving the crystallographic R factors and sharpening anomalous differences that are near the level of the noise

    Vehicle detection in still images is a comparatively difficult task.This paper presents a method for this task by using boosted local pattem detector constructed from two local features including Haar-like and oriented gradient features.The whole process is composed of three stages.In the first stage,local appearance features of vehicles and non-vehicle objects are extracted.Haar-like and oriented gradient features arc extracted separately in this stage as local features.In the second stage,Adaboost algorithm is used to select the mast discriminative features as weak detectors from the two local feature sets,and a strong local pattern detector is built by the weighted combination of these selected weak detectors.Finally,vehicle detection can be performed in still images by using the boosted strong local feature detector.Experiment results show that the local pattern detectur constructed in this way combines the advantages of Haar-like and oriented gradient features,and can achieve better detection results than the datector by using single Haar-like features.

  11. Spiral multiple-effect diffusion solar still coupled with vacuum-tube collector and heat pipe

    Huang, Bin-Juine

    2015-04-01

    © 2015 Elsevier B.V. A novel solar still with spiral-shape multiple-effect diffusion unit is developed in the present study. The test results of a 14-effect unit coupled with vacuum-tube solar collector (absorber area 1.08m2) show that the highest daily pure water production is 40.6kgd-1. The measured highest productivity based on the area of glass cover, solar absorber, and evaporating surface is 34.7, 40.6, and 7.96kgm-2d-1, respectively, which are much higher than the published results. The measured solar distillation efficiency is 2.0-3.5. The performance enhancement results mainly from the lateral diffusion process in the spiraled still cell. The vapor flow generated by heat input can flow freely and laterally through the spiral channel down to the end when solar heat input is high. Besides, the larger evaporating and condensing area at the outer cell may increase heat and mass transfer at the outer cell.

We describe in this paper recent advances in a project being undertaken to trial and develop advanced surveillance systems for public safety. In this paper, we propose a local facial feature based framework for both still image and video-based face recognition. The evaluation is performed on a still image dataset LFW and a video sequence dataset MOBIO to compare 4 methods for operation on feature: feature averaging (Avg-Feature, Mutual Subspace Method (MSM, Manifold to Manifold Distance (MMS, and Affine Hull Method (AHM, and 4 methods for operation on distance on 3 different features.

Under the limitation on a small number of images available per person, feature averaging is more reliable than MSM, MMD, and AHM and is much faster. Thus, our proposed framework—averaging MRH feature is more suitable for CCTV surveillance systems with constraints on the number of images and the speed of processing.

  14. Enhancing the stepped solar still performance using internal and external reflectors

    International Nuclear Information System (INIS)

    Highlights: • Stepped solar still with internal and external reflectors have been investigated. • The productivity of the modified stepped solar still is higher than conventional by 103%. • The productivity of stepped still with external mirror is higher than that for conventional still by 88%. - Abstract: The performance of stepped solar still with internal and external reflectors have been investigated in the current study. The reflectors are used to enhance energy input to the stepped still. The influence of internal and external (top and bottom) reflectors on the performance of the stepped solar still is investigated. A comparison between modified stepped solar still and conventional solar still is carried out to evaluate the developed desalination system performance under the same climate conditions. The results indicated that, during experimentation the productivity of the modified stepped solar still with internal and external (top and bottom) reflectors is higher than that for conventional still approximately by 125%. In this case the estimated cost of 1 l of distillate for stepped still with reflectors and conventional solar stills is approximately 0.031$ and 0.049$, respectively

    Full Text Available Many people use digital still cameras to take photographs in contemporary society. Significant amounts of digital information have led to the emergence of a digital era. Because of the small size and low cost of the product hardware, most image sensors use a color filter array to obtain image information. However, employing a color filter array results in the loss of image information; thus, a color interpolation technique must be employed to retrieve the original picture. Numerous researchers have developed interpolation algorithms in response to various image problems. The method proposed in this study involves integrating discrete wavelet transform (DWT into the interpolation algorithm. The method was developed based on edge weight and partial gain characteristics and uses the basic wavelet function to enhance the edge performance and processes of the nearest or larger and smaller direction gradients. The experiment results were compared to those of other methods to verify that the proposed method can improve image quality.

  16. Enhancement of modified solar still integrated with external condenser using nanofluids: An experimental approach

    International Nuclear Information System (INIS)

    Highlights: • The effect of using nanofluids on the solar still performance is investigated. • The solar still with external condenser increases the productivity by about 53.2%. • Using nanofluids improves the solar still water productivity by about 116%. - Abstract: The distilled water productivity of the single basin solar still is very limited. In this context, the design modification of a single basin solar still has been investigated to improve the solar still performance through increasing the productivity of distilled water. The experimental attempts are made to enhance the solar still productivity by using nanofluids and also by integrating the still basin with external condenser. The used nanofluid is the suspended nanosized solid particles of aluminum-oxide in water. Nanofluids change the transport properties, heat transfer characteristics and evaporative properties of the water. Nanofluids are expected to exhibit superior evaporation rate compared with conventional water. The effect of adding external condenser to the still basin is to decrease the heat loss by convection from water to glass as the condenser acts as an additional and effective heat and mass sink. So, the effect of drawn vapor at different speeds was investigated. The results show that integrating the solar still with external condenser increases the distillate water yield by about 53.2%. And using nanofluids improves the solar still water productivity by about 116%, when the still integrated with the external condenser

  17. An experimental approach to improve the basin type solar still using an integrated natural circulation loop

    International Nuclear Information System (INIS)

    Highlights: • A new experimental approach to improve the conventional solar still performances is proposed. • A passive natural circulation loop is integrated to the conventional solar still. • Natural circulation of humid-air in a closed loop is studied by the present study. • Natural circulation capability in driving air convection in the still was demonstrated. • Air convection created inside the still increase the evaporation heat and mass transfer. - Abstract: In this paper, a new experimental approach is proposed to enhance the performances of the conventional solar still using the natural circulation effect inside the still. The idea consists in generating air flow by a rectangular natural circulation loop appended to the rear side of the still. The proposed still was tested during summer period and the experimental data presented in this paper concerns four typical days. The convective heat transfer coefficient is evaluated and compared with Dunkle’s model. The comparison shows that convective heat transfer is considerably improved by the air convection created inside the still. The natural circulation phenomenon in the still is studied and a good agreement between the experimental data and Vijajan’s laminar correlation is found. Therefore, natural circulation phenomenon is found to have a good effect on the still performances where the still daily productivity is of 3.72 kg/m2 and the maximum efficiency is of 45.15%

    2011-01-01

    Full Text Available The clean and pure drinking water is important in today's life but current water sources are usually brackish with bacteria that cannot be used for drinking. About 78% of water available in the sea is salty, 21% of water is brackish, and only 1% of water is fresh. Distillation is one of the feasible processes applied to water purification, and it requires the energy inputs, such as solar radiation. Water is evaporated in this distillation process and water vapor can be separated and condensed to pure water. Now, with the change from conventional fuels to renewable and environment friendly fuels sources, the modern technology allows to use the abundant energy from the sun. It is better to use solar energy to process the water desalination since it is more economical than the use of conventional energies. The main focus of this paper is applying computer-aided modeling and simulation to design a less complex solar water distillation system. The prototype of this solar still system is also built to verify its feasibility, functionality, and reliability. The computational simulation and prototype testing show the reliability and proper functionality of this solar water distillation system.

  2. Unattended real-time re-establishment of visibility in high dynamic range video and stills

    2014-05-01

    We describe a portable unattended persistent surveillance system that corrects for harsh illumination conditions, where bright sun light creates mixed contrast effects, i.e., heavy shadows and washouts. These effects result in high dynamic range scenes, where illuminance can vary from few luxes to a 6 figure value. When using regular monitors and cameras, such wide span of illuminations can only be visualized if the actual range of values is compressed, leading to the creation of saturated and/or dark noisy areas and a loss of information in these areas. Images containing extreme mixed contrast cannot be fully enhanced from a single exposure, simply because all information is not present in the original data. The active intervention in the acquisition process is required. A software package, capable of integrating multiple types of COTS and custom cameras, ranging from Unmanned Aerial Systems (UAS) data links to digital single-lens reflex cameras (DSLR), is described. Hardware and software are integrated via a novel smart data acquisition algorithm, which communicates to the camera the parameters that would maximize information content in the final processed scene. A fusion mechanism is then applied to the smartly acquired data, resulting in an enhanced scene where information in both dark and bright areas is revealed. Multi-threading and parallel processing are exploited to produce automatic real time full motion corrected video. A novel enhancement algorithm was also devised to process data from legacy and non-controllable cameras. The software accepts and processes pre-recorded sequences and stills, enhances visible, night vision, and Infrared data, and successfully applies to night time and dark scenes. Various user options are available, integrating custom functionalities of the application into intuitive and easy to use graphical interfaces. The ensuing increase in visibility in surveillance video and intelligence imagery will expand the performance and

  4. An ideal internally heat integrated batch distillation with a jacketed still with application to a reactive system

    International Nuclear Information System (INIS)

    Batch distillation is an irreversible process and consumes many times the theoretical minimum energy requirement. The present work focuses on the development of an internally heat integrated batch distillation with a jacketed still (IHIBDJS) aiming to reduce the degree of irreversibility towards zero. The IHIBDJS scheme consists of a rectifying tower equipped with an overhead condenser and a still pot or reboiler that surrounds the tower concentrically. For improving the energy efficiency by the reduction of external energy input, the rectifier is operated at an elevated pressure so that a thermal driving force should exist between the rectifying tower and the concentric still. For this purpose, an isentropic compression system is mounted in the reboiled vapor line. Aiming to reduce further the degree of process irreversibility, we propose an additional thermal arrangement into the IHIBDJS configuration that couples the overhead vapor with the reboiler liquid, thereby reducing further the external heat consumption. It is investigated for a reactive batch distillation column that the effective use of internal heat sources would make the heat integrated column an independent scheme of external heat source. - Highlights: • An internal heat integration approach is developed for batch distillation. • Further intensification is made by thermally coupling top vapor with still liquid. • A reactive system is used to illustrate the proposed scheme

I argue how the discussion on disciplines reminds us of a debate on politics and identities.

  6. Performance evaluation of a continuous flow inclined solar still desalination system

    International Nuclear Information System (INIS)

    Highlights: • A mathematical model was presented to analyze the performance of inclined still. • The effect of air speed, water masses, film thickness and velocity was studied. • Productivity for the Model 3 was higher than conventional still by 57.2%. • The performance was strongly affected by water film thickness and velocity. • Model 3 gave the highest performance while Model 1 gave the lowest performance. - Abstract: In the present work, theoretical study of the performance evaluation of a continuous water flow inclined solar still desalination system is performed. Three models are studied for inclined solar still desalination system with and without water close loop. The effects of the water mass, water film thickness, water film velocity and air wind velocity on the performance of the three models are studied. The results show that the inclined solar still with a makeup water is superior in productivity (57.2% improvement) compared with a conventional basin-type solar still. Also, the application of inclined solar still with open water loop is recommended when combined with other still desalination system due to high water temperature output. The inclined solar still with a makeup (Model 3) gives the highest performance while Model 1 gives the lowest performance. Finally, the water film thickness, and velocity as well as wind velocity plays important roles in improving the still productivity and efficiency

    Full Text Available Characteristically shaped bifacial points are stone artefacts with which the Middle Stone Age Still Bay techno-complex in Southern Africa is identified. Traditional approaches such as chaîne opératoire and two-dimensional metrics in combination with attribute analyses have been used to analyse variability within Still Bay point assemblages. Here we develop a protocol to extract and analyse high resolution 3-dimensional geometric morphometric information about Still Bay point morphology. We also investigate ways in which the independent variables of time, raw-material and tool size may be driving patterns of shape variation in the Blombos Cave point assemblage. We demonstrate that at a single, stratified Still Bay site points undergo significant modal changes in tool morphology and standardization. Our results caution against (1 treatment of the Still Bay as a static technological entity and (2 drawing demographic inferences stemming from grouping Still Bay point collections within the same cultural label.

  9. Prediction of the performance of a compact-evacuated solar still

    International Nuclear Information System (INIS)

    This paper reports the development of a mathematical model to predict the productivity and the thermal characteristics of a compact two-stage solar still with a heat recovery. A simple cost analysis is carried out to shed some lights on the potential of utilizing the proposed still for the production of drinking water. It was found that by creating a vacuum in the still as well as using the heat recovery from the condensation of the first stage into the evaporation in the second stage could result in a maximum distillation efficiency of 60%. The predicted yield of the still is 1.6 kg/h. (Author)

    Drobny, Hans G.

    2016-02-01

    Full Text Available The introduction and availability of highly active and selective herbicides in all important field crops, in the last decades, enabled the simplification and money saving in crop rotations and agronomic measures. This resulted in respective specialized and adapted weed populations, and consequently an increasing selection of resistant populations. Since the introduction of the ALS-inhibitors (starting 1985 and the 4-HPPD-inhibitors (2001, no new MoA-Classes were registered, and there are none in the registration process. Several established herbicides were not registered or re-registered in the EU, or were severely restricted in their application. The cost and the risk to develop and register a new selective herbicide in the EU are hardly justified, in relation to their market potential. The only solution on problem fields, with resistant populations, is to change the agronomic practices, like crop rotation, soil tillage, seeding time, etc., as a precautionary principle also on still „normal“ fields. The different advising institutions have to integrate these aspects into their recommendations, besides the proper herbicide management.

    Securing digital images is becoming an important concern in today’s information security due to the extensive use of secure images that are either transmitted over a network or stored on disks. Image encryption is the most effective way to fulfil confidentiality and protect the privacy of images. Nevertheless, owing to the large size and complex structure of digital images, the computational overhead and processing time needed to carry out full image encryption prove to be limiting factors that inhibit it of being used more heavily in real time. To solve this problem, many recent studies use the selective encryption approach to encrypt significant parts of images with a hope to reduce the encryption overhead. However, it is necessary to realistically evaluate its performance compared to full encryption. In this paper, we study the performance and efficiency of image segmentation methods used in the selective encryption approach, such as edges and face detection methods, in determining the most important parts of visual images. Experiments were performed to analyse the computational results obtained by selective image encryption compared to full image encryption using symmetric encryption algorithms. Experiment results have proven that the selective encryption approach based on edge and face detection can significantly reduce the time of encrypting still visual images as compared to full encryption. Thus, this approach can be considered a good alternative in the implementation of real-time applications that require adequate security levels.

  12. The Looming Shadows of the Walls. Is a Cosmopolitan Europe still Possible?

    Directory of Open Access Journals (Sweden)

    Vincenzo Cicchelli

    2015-01-01

    Full Text Available In a Europe of many lights and shadows, cosmopolitan sociology provides a valid theoretical framework to distinguish one from the other. If cosmopolitan sociology is an attempt to understand how individuals, social groups and institutions deal with the challenges of ever more transnational social processes, then the European issue can be fully inserted within such an approach. From this point of view, following the austerity policies and recent events involving Syrian refugees and the attack by Daesh activists at the heart of Europe, sociology has started to enquire whether a cosmopolitan Europe is still possible. Conversaly, in the history of Europe and in its Constitutional Treaties, traces of cosmopolitanism are to be found almost everywhere. In this context, our study examines the crisis pervading Europe today and highlights the standing back to a certain extent of cosmopolitan sociology. At the same time, it stresses the hope that a change of direction will occur and the opportunity grasped of reflecting more deeply on the founding principles of cosmopolitan Europe.

    Probabilistic phonotactic knowledge facilitates perception, but categorical phonotactic illegality can cause misperceptions, especially of non-native phoneme combinations. If misperceptions induced by first language (L1) knowledge filter second language input, access to second language (L2) probabilistic phonotactics is potentially blocked for L2 acquisition. The facilitatory effects of L2 probabilistic phonotactics and categorical filtering effects of L1 phonotactics were compared and contrasted in a series of cross-modal priming experiments. Dutch native listeners and L1 Spanish and Japanese learners of Dutch had to perform a lexical decision task on Dutch words that started with /sC/ clusters that were of different degrees of probabilistic wellformedness in Dutch but illegal in Spanish and Japanese. Versions of target words with Spanish illegality resolving epenthesis in the clusters primed the Spanish group, showing an L1 filter; a similar effect was not found for the Japanese group. In addition, words with wellformed /sC/ clusters were recognised faster, showing a positive effect on processing of probabilistic wellformedness. However, Spanish learners with higher proficiency were facilitated to a greater extent by wellformed but epenthesised clusters, showing that although probabilistic learning occurs in spite of the L1 filter, the acquired probabilistic knowledge is still affected by L1 categorical knowledge. Categorical phonotactic and probabilistic knowledge are of a different nature and interact in acquisition. PMID:26529903

  14. Structural and Functional Comparisons of Retroviral Envelope Protein C-Terminal Domains: Still Much to Learn

    Directory of Open Access Journals (Sweden)

    Jonathan D. Steckbeck

    2014-01-01

    Full Text Available Retroviruses are a family of viruses that cause a broad range of pathologies in animals and humans, from the apparently harmless, long-term genomic insertion of endogenous retroviruses, to tumors induced by the oncogenic retroviruses and acquired immunodeficiency syndrome (AIDS resulting from human immunodeficiency virus infection. Disease can be the result of diverse mechanisms, including tumorigenesis induced by viral oncogenes or immune destruction, leading to the gradual loss of CD4 T-cells. Of the virally encoded proteins common to all retroviruses, the envelope (Env displays perhaps the most diverse functionality. Env is primarily responsible for binding the cellular receptor and for effecting the fusion process, with these functions mediated by protein domains localized to the exterior of the virus. The remaining C-terminal domain may have the most variable functionality of all retroviral proteins. The C-terminal domains from three prototypical retroviruses are discussed, focusing on the different structures and functions, which include fusion activation, tumorigenesis and viral assembly and lifecycle influences. Despite these genetic and functional differences, however, the C-terminal domains of these viruses share a common feature in the modulation of Env ectodomain conformation. Despite their differences, perhaps each system still has information to share with the others.

  15. Arrhythmias induced cardiomyopathies: the riddle of the chicken or the egg still unresolved?

    International Nuclear Information System (INIS)

    The hypothesis testing of inappropriate fast, irregular, or asynchronous myocardial contraction provoking cardiomyopathy has been the primary focus of numerous research efforts, especially during the last few decades. Rapid ventricular rates resulting from supraventricular arrhythmias and atrial fibrillation (AF), irregularity of heart rhythm basic element of AF and asynchrony, as a consequence of right ventricular pacing, bundle branch block, or frequent premature ventricular complexes, have been established as primary causes of arrhythmia-induced cardiomyopathy. The main pathophysiological pathways involved have been clarified, including neurohumoral activation, energy stores depletion, and abnormalities in stress and strain. Unfortunately, from a clinical point of view, patients usually seek medical advice only when symptoms develop, while the causative arrhythmia may be present for months or years, resulting in myocardial remodelling, diastolic, and systolic dysfunction. In some cases, making a definite diagnosis may become a strenuous exercise for the treating physician, as the arrhythmia may not be present and, additionally, therapy must be applied for the diagnosis to be confirmed retrospectively. The diagnostic process is also hardened due to the fact that strict diagnosing criteria are still a matter of discrepancy

    Directory of Open Access Journals (Sweden)

    Klaus Speidel

    2013-06-01

    Full Text Available That the same story can be told in different media is one of the fundamental claims of narratology. Claude Bremond (1964 famously listed verbal narrative, novels, theater, movies and ballet among potential vehicles for story. He thus prepared the ground for narratology’s future as a discipline engaged in narrative research across media, in principle including single still pictures. However, narratological research concerned with pictorial narrativity generally proceeds from the assumption that although single pictures may evoke or imply stories, they are unsuitable for storytelling in a strict narratological sense. Focusing on the key issue of temporality, this essay will show that a single still picture may indeed tell “a story proper” (Wolf 2003, 180 and can thus be regarded as a narrative, even according to a narrow definition.

    2014-01-01

    Desalination methods based on renewable energy offer a promising solution to both water shortage and environmental degradation problems that continue to grow globally. The solar still is one such method that uses a sustainable energy source to produce potable water albeit at a relatively low productivity rate. A new modification has been introduced to the conventional solar still to enhance its productivity. The modification consists of a light weight, black finished, slowly-rotating drum, which leads to a sustainable, cost-effective, and low-tech amendment that preserves the key features of the still while considerably increasing its yield compared to a control still that does not include the drum. In this paper, three different cover geometries of the modified still are studied and the effect of cover design on the performance of the still in terms of measured temperatures and productivity is considered. The three cover designs are as follows: double-sloped or triangular, single-sloped and curved cover. In addition, a conventional double-sloped still without the rotating drum is operated in parallel as a control and the findings of this study are reported and discussed. © 2014 Published by Elsevier Ltd.

    International Nuclear Information System (INIS)

    In this paper, the optimization of a PV/T (photovoltaic/thermal) active solar still is carried out. Analytical expressions for glass cover temperature, basin temperature, brackish water temperature and fresh water productivity are obtained by writing energy balance for different components of PV/T active solar still. The output electrical power of PV/T active solar still is calculated by four-parameter I–V (current–voltage) model. Objective function in present study is the energy efficiency of PV/T active solar still. A computer simulation program has been developed in order to obtain thermal and electrical parameters, respectively. The simulation results of the present study are in fair agreement with the experimental data of previous literatures. Finally, the optimization of PV/T active solar still has been carried out and the optimized value of mass flow rate, number of PV/T collector and the objective function have been obtained. Furthermore, the effect of various operating parameters on energy efficiency have been investigated. - Highlights: • The comprehensive optimization of a PV/T active solar still is carried out. • Present study is based on numerical simulation. • A modified energy efficiency for PV/T active solar still is obtained. • The effect of design and operating parameters is investigated on energy efficiency

    This paper presents a theoretical analysis of a basin type solar still with an internal reflector (two sides and back walls) and an inclined flat plate external reflector on a winter solstice day at 30 N latitude. We are proposing a new geometrical method for calculating the solar radiation reflected by the inclined external reflector and then absorbed on the basin liner. Using this method, we performed a numerical analysis of heat and mass transfer in the still in order to determine the effectiveness of the inclination of the external reflector. We found that the benefit of a vertical external reflector would be smaller or even negligible for a still with a larger value for the glass cover angle, while an inclined external reflector can increase the distillate productivity of the still at any glass cover angle, and the external reflector angle should be set at about 15 from vertical on a winter solstice day. The daily amount of distillate of the still with the inclined external reflector would be about 16% greater than that with the vertical external reflector, and about 2.3 times as large as that of the still with neither the internal nor the external reflector on a winter solstice day.

  1. Critical variables in the performance of a productivity-enhanced solar still

    KAUST Repository

    Ayoub, George M.

    2013-12-01

    A new and sustainable modification has been introduced into the conventional solar still, considerably increasing its productivity. This enhancement in the solar still productivity is achieved without forsaking the basic features of the still such as low cost, ease of handling, sustainability, water quality, material availability, low maintenance and space conservation. The introduced modification is in the form of a slowly rotating hollow drum within the still cavity that allows the formation of thin water films, which evaporate rapidly. Several environmental and operational parameters attribute to the optimization of the new still design. Environmental factors refer primarily to weather conditions such as solar intensity, relative humidity, ambient temperature and wind speed and direction. Operational variables include drum speed, brine depth in the basin, cover cooling and other related parameters such as the materials used and the still configuration. The influence of these parameters is discussed and their impact on productivity is investigated in detailed order to identify existing correlations and optimize design and operation of the new system. An error analysis was conducted for all experimental data obtained from this study. © 2013 Elsevier Ltd.

  3. Experimental and numerical investigation on a novel solar still with vertical ripple surface

    International Nuclear Information System (INIS)

    Highlights: • A novel diffusion-type solar still was designed to improve the stability. • Basic parameters were obtained by the steady-state experiments. • An empirical correlation for the corrugated distillation cavity has been given. • The performance of the still under environment conditions was investigated. - Abstract: Since the great potential of Solar desalination in providing access to freshwater for arid areas, a novel solar still with better performance was designed in the paper. Compared with the other vertical multi-effect diffusion-type solar still (VMEDS), the proposed one owns the following merits: (1) better reliability and anti-scale security due to that the saline-soaked wicks (porous) were replaced by water troughs on the vertical plate; (2) more compact structure, decreasing the heat loss and facilitating the operation. Before the test under environment conditions, steady-state experiments with electricity as heating power were carried out to obtain several basic parameters, including the temperature distribution and freshwater yield of the novel solar still. Results indicated that the accumulated freshwater yield decreased from the first to the third stage during the test, with the maximum performance ratio of 1.81. An empirical correlation in terms of Nu and Ra number was given against the steady-state data, based on which a model was developed for predicting the heat transfer performance of the still under environment conditions. Following that experiment under environment conditions was performed, by which the new model was validated. Further analysis by the model indicated that inadequate heat insulation caused significant heat loss and reduction of the freshwater yield. And the highest distillation efficiency (performance ratio) of the four sample days in a year was up to 2.0 for the optimized still

    Methods for evaporating oil produced water (OPW) have been tested and used to remove salinity by means of solar energy. The aim of the present study was to assess the application of a conventional solar still in the desalination of treated OPW, investigating the temperatures reached and comparing them with solar radiation levels. The solar distillation equipment consisted of a two-water single effect passive solar still. The still was fed with treated OPW. Temperatures were recorded using data loggers with PT100 sensors. The experiments were conducted between February and April 2008. The temperatures obtained are consistent with the type of still used and the seasons of the year. The maximum recorded temperatures varied between 49.9 deg C and 63.8 deg C. The distilled volume ranged between 48 and 240 mL/h. The estimated daily amount produced was compatible with literature values. The results show that the single-effect solar still can also be used to desalinate treated OPW. (author)

    In an attempt to improve the daily productivity of the single effect solar stills, a single-slope single-basin solar still integrated with a shallow solar pond (SSP) was studied to perform solar distillation at a relatively high temperature. The energy balance equations of various elements of the considered system were formulated and solved analytically. Suitable computer programs were prepared for optimizing and predicting the thermal performance of the considered system. Numerical calculations were carried out on typical summer and winter days in Tanta (latitude 30 47'N) for different thicknesses and mass flow rates of the flowing water to study the effect of these parameters on the daily productivity and efficiency of the system. To validate the proposed theoretical model, comparisons between calculated and measured results were carried out. Good agreement has been achieved. The year-round performances of the still with and without the SSP were also investigated. The optimum values of the flowing water thickness and the mass flow rate for this typical configuration of the SSP-active solar still were obtained as 0.03 m and 0.0009 kg/s. The annual average values of the daily productivity anti P{sub d} and efficiency anti {eta}{sub d} of the still with the SSP were found to be higher than those obtained without the SSP by 52.36% and 43.80%, respectively.

    Ayoub, George M.

    2014-02-01

    Solar still desalination systems offer sustainable tools for fresh water production. However, their widespread application is often hindered by their relatively low production rates compared to other desalination methods. In this study, a simple amendment, in the form of a slowly-rotating hollow cylinder, was introduced within the solar still, significantly increasing the evaporative surface area. This new modified still was analyzed in terms of both operation and economic feasibility. The introduced cylinder resulted in a 200-300% increase in water output relative to a control, which did not include the cylinder. The resulting percent improvement far exceeds that obtained by other modifications. Unit production cost estimates varied between 6 and 60$/m3 depending on discount rates, productivity, service lifetime and initial capital costs. These projections are well within reported cost ranges for renewable-based technologies. In order to evaluate the system\\'s feasibility in real market value, different scenarios that introduce carbon-trading schemes and environmental degradation costs for fuel-based desalination, were performed. Reported costs for fuel-based brackish water and seawater desalination were thus adjusted to include unaccounted-for costs related to environmental damage. This analysis yielded results that further justify the economic feasibility of the new modified solar still, particularly for seawater desalination. © 2013 Elsevier B.V.

  17. Development of the still stand rain gauge for recording rainfall stratigraphy

    International Nuclear Information System (INIS)

    Storage gauges preserve nothing of the magnitude, number, and arrival time of individual rainfall events which sum to make up the total water depth in the gauge. To overcome the restrictive nature of storage gauges when studying the spatial variation of individual rainfall events, a 'still stand recording rain gauge' has been developed which records the depth of each rainfall event. The term 'still stand recording rain gauge' is from the concept where a collimated radioactive source, cobalt 57, mounted on top of a float in a modified storage gauge which has its intensity calibrated so that each rainless period generates a line on a protected X-ray film. Rainfall magnitudes are thus the vertical intervals between consecutive horizontal lines on the film In effect, the gauge creates a stratigraphic column of rainfall at a given location, and each rainfall 'layer' can be correlated to equivalent layers in nearby still stand gauges for spatial rainfall analysis. The application of the still stand gauge is illustrated with both a transect of twelve gauges across a mountain range and a grid of mine gauges on low relief land

  18. Still Heart Encodes a Structural HMT, SMYD1b, with Chaperone-Like Function during Fast Muscle Sarcomere Assembly.

    Directory of Open Access Journals (Sweden)

    Kendal Prill

    Full Text Available The vertebrate sarcomere is a complex and highly organized contractile structure whose assembly and function requires the coordination of hundreds of proteins. Proteins require proper folding and incorporation into the sarcomere by assembly factors, and they must also be maintained and replaced due to the constant physical stress of muscle contraction. Zebrafish mutants affecting muscle assembly and maintenance have proven to be an ideal tool for identification and analysis of factors necessary for these processes. The still heart mutant was identified due to motility defects and a nonfunctional heart. The cognate gene for the mutant was shown to be smyd1b and the still heart mutation results in an early nonsense codon. SMYD1 mutants show a lack of heart looping and chamber definition due to a lack of expression of heart morphogenesis factors gata4, gata5 and hand2. On a cellular level, fast muscle fibers in homozygous mutants do not form mature sarcomeres due to the lack of fast muscle myosin incorporation by SMYD1b when sarcomeres are first being assembled (19hpf, supporting SMYD1b as an assembly protein during sarcomere formation.

    Full Text Available The objective of the paper is to assess the reasons for the current negative position of the Czech Government towardeuro adoption and to find out whether the expected benefits of euro adoption for Czech companies still remain. Thepostponement of euro adoption in the Czech Republic has mainly been caused by the current problems of the euroarea. The benefits arising from euro adoption are subject to the reduction of the exchange rate volatility and of thetransaction costs, whereas they also depend on the degree of integration with the euro area. These benefits may stillbe expected – neither the financial crisis nor the economic recession has affected them. The integration of the Czecheconomy with the euro area is high and still growing. Therefore, euro adoption will lead to the stimulation of mutual tradeof the Czech Republic and the euro area.

  1. Still indispensable: how modern parties need grass roots activists for campaigning and sustaining democracy

    OpenAIRE

    2014-01-01

    This dissertation argues that modern political parties still need grass roots activists for campaigning and sustaining democracy. Western European parties have lost members at an increasing rate over the last 50 years and the decline shows no signs of stopping, but existing literature on party organization and campaigning holds that this is mostly unproblematic, since parties have also changed the way they operate. Since the dawn of the professionalized, media-centered campaign...

    Mycobacterial infection is re-emerging as a major health care concern. Although Mycobacterium tuberculosis (MTB) is still the most important pathogen, atypical mycobacterium (AMB) infections are becoming increasingly common. We present a pictorial review of the imaging features of these infections in the chest, abdomen, brain and musculoskeletal system. Imaging similarities and differences between the normal and the immunocompromised host will be highlighted. Koh, D. M. et al. Clinical Radiology (2001)

    This MA thesis investigates Norwegian teachers' and students' attitudes toward British English and American English. To the best of my knowledge no previous language studies have been conducted on both of these groups in Norway. British English had traditionally been the variety taught at European schools (Trudgill & Hannah 2008). On the other hand, Norwegians are arguably exposed to more American English than British English in their daily lives. The results show that British English still h...

    This thesis explores a particular Tacitean phrase, which occurs twice in his corpus. I argue that this phrase is intentionally ambiguous and reflects Tacitus' clever use of heightened rhetoric. "Incolumi adhuc Galba" occurs twice in Tacitus' "Historiae," and is commonly understood and translated to while Galba was still alive." This interpretation is, by all means, correct, but it does not represent the range of meanings in the phrase. It is my claim that Tacitus deliber...

    Recognizing actions from still images is popularly studied recently. In this paper, we model an action class as a flexible number of spatial configurations of body parts by proposing a new spatial SPN (Sum-Product Networks). First, we discover a set of parts in image collections via unsupervised learning. Then, our new spatial SPN is applied to model the spatial relationship and also the high-order correlations of parts. To learn robust networks, we further develop a hierarchical spatial SPN ...

    The US recession of 1937–8 is one of the deepest on record. Yet it did not produce a global depression – quite unlike 1930. According to the standard view, this reflected an unfettering of central banking after the collapse of the international gold standard circa 1931. We challenge this view. While Germany and a couple of Central and Eastern European countries were sheltered by binding exchange controls, most countries were still constrained by their golden fetters, as our new exchange rate ...

    Chan Ding training is beneficial to health and emotional wellbeing. More and more people have taken up this practice over the past few years. A major training method of Chan Ding is to focus on the ten Mailuns, i.e., energy points, and to maintain physical stillness. In this article, wireless wearable accelerometers were used to detect physical stillness, and the created physical stillness index (PSI) was also shown. Ninety college students participated in this study. Primarily, accelerometers used on the arms and chest were examined. The results showed that the PSI values on the arms were higher than that of the chest, when participants moved their bodies in three different ways, left-right, anterior-posterior, and hand, movements with natural breathing. Then, they were divided into three groups to practice Chan Ding for approximately thirty minutes. Participants without any Chan Ding experience were in Group I. Participants with one year of Chan Ding experience were in Group II, and participants with over three year of experience were in Group III. The Chinese Happiness Inventory (CHI) was also conducted. Results showed that the PSI of the three groups measured during 20-30 min were 0.123 ± 0.155, 0.012 ± 0.013, and 0.001 ± 0.0003, respectively (p < 0.001 ***). The averaged CHI scores of the three groups were 10.13, 17.17, and 25.53, respectively (p < 0.001 ***). Correlation coefficients between PSI and CHI of the three groups were -0.440, -0.369, and -0.537, respectively (p < 0.01 **). PSI value and the wearable accelerometer that are presently available on the market could be used to evaluate the quality of the physical stillness of the participants during Chan Ding practice.

  20. Are Lipases Still Important Biocatalysts? A Study of Scientific Publications and Patents for Technological Forecasting.

    Directory of Open Access Journals (Sweden)

    Karina de Godoy Daiha

    Full Text Available The great potential of lipases is known since 1930 when the work of J. B. S. Haldane was published. After eighty-five years of studies and developments, are lipases still important biocatalysts? For answering this question the present work investigated the technological development of four important industrial sectors where lipases are applied: production of detergent formulations; organic synthesis, focusing on kinetic resolution, production of biodiesel, and production of food and feed products. The analysis was made based on research publications and patent applications, working as scientific and technological indicators, respectively. Their evolution, interaction, the major players of each sector and the main subject matters disclosed in patent documents were discussed. Applying the concept of technology life cycle, S-curves were built by plotting cumulative patent data over time to monitor the attractiveness of each technology for investment. The results lead to a conclusion that the use of lipases as biocatalysts is still a relevant topic for the industrial sector, but developments are still needed for lipase biocatalysis to reach its full potential, which are expected to be achieved within the third, and present, wave of biocatalysis.

The emergence date of osteopathy is considered to be 22 June 1874. Historically, modern osteopathy has come into existence not so long. We are almost contemporaries of it and its author, but despite this, the international osteopathy community is romanticizing and mythologizing the personality of A.T. Still. In our opinion, the reason is his magnetic personality and brilliant life. Thanks to A.T. Still’s personality, osteopathy may not have been lost among many medical areas and discoveries and continues to develop and attract new supporters. On the other hand, osteopathy is, in the opinion of its founder, a science; therefore a historical rather than mythological approach to A.T. Still’s bibliography, which takes into account all factors for personality formation, is considered correct. Modern science tells that these factors are inheritance, environment, and education. The authors have applied just this scientific approach and, without demolishing the myths, set forth an aim to study the factors forming the world outlook of A.T. Still in order to predict a further way to develope osteopathy in our country.

    Athletes in sports such as the gymnastics who perform the still rings cross position are disadvantaged due to a lack of objective and convenient measurement methods. The gymnastics “cross ”is a held isometric strength position considered fundamental to all still rings athletes. The purpose of this investigation was to determine if two small force platforms (FPs) placed on supports to simulate a cross position could demonstrate the fidelity necessary to differentiate between athletes who could perform a cross from those who could not. Ten gymnasts (5 USA Gymnastics, Senior National Team, and 5 Age Group Level Gymnasts) agreed to participate. The five Senior National Team athletes were grouped as cross Performers; the Age Group Gymnasts could not successfully perform the cross position and were grouped as cross Non- Performers. The two small FPs were first tested for reliability and validity and were then used to obtain a force-time record of a simulated cross position. The simulated cross test consisted of standing between two small force platforms placed on top of large solid gymnastics spotting blocks. The gymnasts attempted to perform a cross position by placing their hands at the center of the FPs and pressing downward with sufficient force that they could remove the support of their feet from the floor. Force-time curves (100 Hz) were obtained and analyzed for the sum of peak and mean arm ground reaction forces. The summed arm forces, mean and peak, were compared to body weight to determine how close the gymnasts came to achieving forces equal to body weight and thus the ability to perform the cross. The mean and peak summed arm forces were able to statistically differentiate between athletes who could perform the cross from those who could not (p < 0.05). The force-time curves and small FPs showed sufficient fidelity to differentiate between Performer and Non- Performer groups. This experiment showed that small and inexpensive force platforms may serve as

    A model of solar still assisted by ejector has been built from a previous design. The dimensions of this model are: 0.15 m wide; 0.80 m long and 0.20 m height to the top of the double slope cover. With these dimensions the cross sectional area results in 0.12 m{sup 2}. The bottom tray was filled with water up to a height of 5 cm. In order to raise the temperature of the water in the tray to a proper value, a 500 W electrical resistance was placed into it. The solar still was built with acrylic walls and the cover was made with 3 mm glass at an angle of 20 degrees respect to the horizontal, as to adjust to Mexico's city latitude. The ejector is 25 cm long with a 0.019 mm cross section. It is placed alongside in the still and as close as possible to the free surface of the water in the tray. The driver fluid, water in this case, is made to flow through the ejector by the air pressure in a tank partially filled with water. The flow rate is regulated by means of a needle valve. The amount of water in the tank is 60 liters approximately. With this water the ejector can operate for one-hour approximately. The pressure in the tank could be adjusted to the equivalent of a 40 m-water column. The water in the still is heated to 40 Celsius degrees. When the interior of the still reaches an uniform temperature, water at 20 Celsius degrees is made to flow through the ejector. The operation of the still is intermittent. The results are presented in a table and they show that performance of the still could be greatly improved.

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available The purpose of this paper is to pick up a thesis from Schmitt, according to which law is not totally contained in its norms, but requires a concrete order besides these. I claim that by following such a principle, the theory of law increases his descriptive and explicative power. In particular, one can thus go beyond the day-to-day, technical knowledge of lawyers and judges, and render a proper explanation of the genesis and dynamical change of legal systems in general. Among other things, the said principle enables the theorist to construe the process that made it possible for the legal systems of modern societies to become autonomous. Yet, on the other hand, I make a critical remark against Schmitt’s belief that by thus explaining the relationship between a concrete order and its legal norms the latter are justified. Against this, I claim that they most comply with some kind of universal principle of justice. I support my claim against Schmitt on an argument of his own-one that he uses to buttress his view that the acknowledgment of the diversity of the human world is a prerequisite for keeping social conflict from becoming violent, and for turning it into a strictly political practice.

    El objetivo de este trabajo es recuperar la tesis de Schmitt en la que afirma que el derecho no se agota en las normas, sino que implica un orden concreto. Ello se debe a que dicha tesis permite ampliar la capacidad descriptiva y explicativa de la teoría jurídica. Especialmente, permite ir más allá del conocimiento técnico que requiere el trabajo cotidiano de los abogados y jueces, para dar cuenta de la génesis y dinámica de los sistema jurídicos. Entre otras cosas permite reconstruir el proceso que hizo posible la autonomía de los sistemas jurídicos propios de las sociedades modernas. Sin embargo, al mismo tiempo, se crítica la creencia de Schmitt respecto a que conceptualizar la relación entre el orden concreto y las normas jur

  6. Is research on soil erosion hazard and mitigation in the Global South still needed? (Alexander von Humbold Medal Lecture)

    Science.gov (United States)

    Poesen, Jean

    2016-04-01

    Soil erosion represents a geomorphological and geological hazard that may cause environmental damage (land degradation), property damage, loss of livelihoods and services as well as social and economic disruption. Erosion not only lowers the quality of our soils on site, resulting in a drastic reduction of their ecosystem functions that play a vital role in daily life, but causes also significant sediment-related problems off site. To curb soil erosion problems, a range of soil conservation techniques and strategies have been designed and are being applied. Worldwide, ca. 62 000 research papers on soil erosion and 116 000 on soil conservation have been published (Web of Science, Dec. 2015). The number of such papers dealing with the Global South represents less than 20 % of all papers, despite the fact that many regions in this part of the world face significant soil erosion problems, aggravated by a rapidly growing population and major environmental changes. Given the large number of research papers on this topic, one might therefore conclude that we now know almost everything about the various soil erosion processes and rates, their factors and consequences as well as their control so that little new knowledge can still be added to the vast amount of available information. We refute this conclusion by pointing to some major research gaps that still need to be addressed if we want to use our soils in a more sustainable way. More specifically the following topics need more research attention: 1) improved understanding of both natural and anthropogenic soil erosion processes and their interactions, 2) scaling up soil erosion processes and rates in space and time, and 3) innovative techniques and strategies to prevent or reduce erosion rates. This will be illustrated with case studies from the Global South. If future research focuses on these research gaps, we will 1) better understand processes and their interactions operating at a range of spatial and temporal

    We report a patient with a clinical picture of suggestive for adult-onset Still's Disease (ASOD) due to Bartonella infection. A 42-year-old immunocompetent man was admitted with fever, rash, arthralgia and sore throat. As his clinical picture suggested ASOD except unusual skin manifestation, we treated him on steroid and ibuprofen. His fever and constitutional symptoms responded immediately within 24hrs of commencing therapy, yet rash and leukocytosis remained. Meanwhile, Bartonella infection was proved by culture of bone marrow. Minocyclin treatment started combined with hydroxychloroquine sulfate and the patient discharged with overall improvement.

    The prevalence of myths preventing people partial to donation in Australia from consenting is unknown. Respondents (N = 468: 381 donors, 26 non-donors, 61 undecided) were surveyed about their (negative) donation beliefs. Approximately 30% of donors were neutral or supported negative beliefs about organ allocation, especially donation to undesirable organ recipients and a black market organ trade. Confusion about brain death, lack of family and religious support, and discomfort with donation were negative beliefs endorsed by some respondents irrespective of donor preference. Proportionally, donors had greater trust in hospitals/doctors than other groups. Some myths still exist but may vary with donation preference. PMID:22304301

    Wolf, Christian; Lerebours, Rachel

    2003-09-19

    An efficient Stille cross-coupling reaction using a variety of aryl halides in neat water has been developed. Employing palladium-phosphinous acid catalyst [(t-Bu)(2)P(OH)](2)PdCl(2) allows formation of biaryls from aryl chlorides and bromides in good to high yields. Functional groups such as ketones and nitriles are tolerated, and organic cosolvents are not required. The air stability and solubility in water of the palladium complexes used in this study facilitate operation of the coupling reaction and product isolation. The feasibility of catalyst recycling has also been demonstrated. PMID:12968920

    The present paper describes experimental investigation on the flow pattern and hydrodynamic effect of underwater gas jets from supersonic and sonic nozzles operated in correct- and imperfect expansion conditions. The flow visualizations show that jetting is the flow regime for the submerged gas injection at a high speed in the parameter range under consideration. The obtained results indicate that high-speed gas jets in still water induce large pressure pulsations upstream of the nozzle exit and the presence of shock-cell structure in the over-and under-expanded jets leads to an increase in the intensity of the jet-induced hydrodynamic pressure.

  16. Expanded Parts Model for Human Attribute and Action Recognition in Still Images

    OpenAIRE

    2013-01-01

    We propose a new model for recognizing human attributes (e.g. wearing a suit, sitting, short hair) and actions (e.g. running, riding a horse) in still images. The proposed model relies on a collection of part templates which are learnt discriminatively to explain specific scale-space locations in the images (in human centric coordinates). It avoids the limitations of highly structured models, which consist of a few (i.e. a mixture of) 'average' templates. To learn our model, we propose an alg...

  18. Experimental investigation on a semi-circular trough-absorber solar still with baffles for fresh water production

    International Nuclear Information System (INIS)

    Highlights: • Experiments are carried out to analyze the performance. • Baffles are placed in the absorber to increase the residence time of water with solar intensity. • Yield of fresh water from present solar still is 16.66% more than a conventional solar still. • Payback period of the present model is quicker. - Abstract: The main objective of this research is to increase the contact time of water in the basin to enhance yield of fresh water by using a semicircular absorber solar still with baffles. An experimental as well as theoretical investigation is carried out. The productivity and efficiency of present still are analyzed with the influence of the number baffles and the water flow rate. A good agreement between the experimental and theoretical results is observed. The results indicate that, the daily yield of present solar still is higher than that for conventional still approximately by 16.66%. The outlet water temperature present solar still is high subsequently, it can be coupled with multi-state of solar stills to increase productivity. Therefore, the present solar still can be sufficiently extended for other continuous solar desalination systems. Economic analysis concluded that, the payback period of the present model solar still is quicker while comparing it with other solar still

  19. Innate immune system still works at diapause, a physiological state of dormancy in insects

    International Nuclear Information System (INIS)

    Highlights: → Two major types of cells are present in the body fluid isolated from the thoracic region of a diapausing pupa. → Phagocytosis and encapsulation by these cells were observed when latex beads as foreign targets were microinjected into a pupa. → Such behavior by these cells was still observed even when pupae were continuously chilled at 4 oC. → Innate cellular reactions can work in diapausing insects in a dormant state. -- Abstract: Diapause is most often observed in insects and is a physiologically dormant state different from other types of dormancy, such as hibernation. It allows insects to survive in harsh environments or extend longevity. In general, larval, pupal, or adult non-diapausing insects possess an innate immune system preventing the invasion of microorganisms into their bodies; however, it is unclear whether this system works under the dormant condition of diapause. We here report the occurrence of innate cellular reactions during diapause using pupae of a giant silkmoth, Samia cynthia pryeri. Scanning electron microscopic analysis demonstrated the presence of two major types of cells in the body fluid isolated from the thoracic region of a pupa. Phagocytosis and encapsulation, characteristics of innate cellular reactions, by these cells were observed when latex beads as foreign targets were microinjected into the internal portion of a pupa. Such behavior by these cells was still observed even when pupae were continuously chilled at 4 oC. Our results indicate that innate cellular reactions can work in diapausing insects in a dormant state.

    Full Text Available The objective of this study was to determine the chemical profile of sugarcane spirits produced by different double distillation methodologies in rectifying still. Fermented sugarcane juice was distilled in rectifying still according to three double distillation methodologies: the methodology used for cognac production; the methodology used for whisky production; and the 10-80-10 percentage composition methodology, referring to the volumes of head, heart and tail of the distillate fractions from the second distillation. For comparison purposes, a simple distilled spirit was also produced. The distillates were analyzed for concentrations of ethanol, copper, volatile acidity, furfural and hydroxymethylfurfural, aldehydes, esters, methanol and higher alcohols. The spirits were also evaluated on the sensory attributes of aroma, taste and preference. Compared to simple distillation, double distillation improved the chemical quality of the spirits, since it has reduced the concentrations of acids, aldehydes, esters, methanol, higher alcohols and, consequently, their coefficient of congeners. Regardless of the methodology employed, the double distillation improved the sensory quality of the spirits since they obtained higher sensory acceptance in relation to spirits produced by simple distillation. Among double distilled spirits, the one produced according to whisky methodology obtained the best scores from appraisers on the aroma and flavor parameters and it was also the most preferred.

  1. Is imatinib still the best choice as first-line oral TKI

    Full Text Available Targeted therapy is the buzz word these days. A decade back the emergence of tyrosine kinase inhibitor Imatinib on the horizon, as the targeted therapy, had captured the imagination of everyone in the field of cancer. It is encouraging to see a large number of patients getting relief from deadly CML disease and leading a good quality of life with the help of this drug. However, sky is not the limit and now we have second and third generation tyrosine kinase inhibitors. I still remember the sagacious smile on the face of late Dr. John Goldman, when I asked him about his preferred choice and he replied and I quote "this is going to be the debate of the decade." Here I take the opportunity to contribute to this debate. I have scrutinized various aspects of the three TKIs, now recommended, for the treatment of CML. I`m still convinced it is too early to shift our practice completely towards 2G TKI as more time is required to make a clear recommendation.

    1999-10-01

    In 1997, Volume 50 of Organic Reactions was published in a handsome and appropriate gold hard-cover edition. This was only the third volume in this prestigious series that consisted of a single chapter. The treatise, The Stille Reaction, describes a palladium-catalyzed cross-coupling between a carbon ligand on tin and a carbon with electrophilic character. This reaction has been around only since 1977, and the literature is covered here through 1994 with a few references in 1995. It is truly astounding that, in the space of about 17 years, a new reaction could generate enough literature for not only a chapter in Organic Reactions, but a complete volume of 652 pages, 864 literature citations, and more than 4300 specific reaction examples. The editorial board of Organic Reactions has graciously decided to make this extensive review available to a broader audience by authorizing a paperback edition of The Stille Reaction. While the mechanistic details of the Stille reaction are generally understood, there are many fine points that must be tuned to each case. For instance, about 15 different solvents have been used, ranging in polarity from benzene to water; at least ten different ligands for the palladium atom are available and they range from hard to soft; CuI, Ag2CO3, and LiCl are sometimes useful cocatalysts but sometimes have no effect, and in some cases LiCl is inhibitory; vinyl triflates couple with alkenyl-, alkynyl- and allylstannanes but not with arylstannanes; reaction temperatures vary from room temperature to refluxing DMF. An important consideration is that most stannanes are reasonably air and moisture stable and do not react with most common functional groups. Thus, it is not necessary to build protection-deprotection sequences into the synthetic scheme. The extensive reaction examples are arranged in 33 tables that show, for each reaction, the structures of the electrophile, the stannane, and the product and specify the catalyst, cocatalyst, solvent

    Full Text Available Athletes in sports such as the gymnastics who perform the still rings cross position are disadvantaged due to a lack of objective and convenient measurement methods. The gymnastics "cross" is a held isometric strength position considered fundamental to all still rings athletes. The purpose of this investigation was to determine if two small force platforms (FPs placed on supports to simulate a cross position could demonstrate the fidelity necessary to differentiate between athletes who could perform a cross from those who could not. Ten gymnasts (5 USA Gymnastics, Senior National Team, and 5 Age Group Level Gymnasts agreed to participate. The five Senior National Team athletes were grouped as cross Performers; the Age Group Gymnasts could not successfully perform the cross position and were grouped as cross Non- Performers. The two small FPs were first tested for reliability and validity and were then used to obtain a force-time record of a simulated cross position. The simulated cross test consisted of standing between two small force platforms placed on top of large solid gymnastics spotting blocks. The gymnasts attempted to perform a cross position by placing their hands at the center of the FPs and pressing downward with sufficient force that they could remove the support of their feet from the floor. Force-time curves (100 Hz were obtained and analyzed for the sum of peak and mean arm ground reaction forces. The summed arm forces, mean and peak, were compared to body weight to determine how close the gymnasts came to achieving forces equal to body weight and thus the ability to perform the cross. The mean and peak summed arm forces were able to statistically differentiate between athletes who could perform the cross from those who could not (p < 0.05. The force-time curves and small FPs showed sufficient fidelity to differentiate between Performer and Non- Performer groups. This experiment showed that small and inexpensive force platforms

    Climate warming raises the question whether high-latitude landscape still function as net carbon (C) sinks. By compiling an integrated C balance for an intensely studied subarctic catchment, we show that this catchment's C balance is not likely to be a strong current sink of C, a commonly held assumption. In fact, it is more plausible (71% probability) that the studied catchment functions as a C source (-11 ± 20 g C m-2 yr-1). Analyses of individual fluxes indicate that soil and aquatic C losses offset C sequestering in other landscape components (e.g., peatlands and aboveground forest biomass). Our results stress the importance of fully integrated catchment C balance estimates and highlight the importance of upland soils and their interaction with the aquatic network for the catchment C balance.

    Full Text Available When designing berths and ship mooring systems near berths, it is necessary to protect ships from dangerous displacements. To make a well-reasoned choice, it is necessary to make estimates of the characteristics of sea wave impact on the ship (with respect to the steady-wave mode in the waters. The results of numeric calculations are better suited for engineering purposes. This paper presents a mathematical model to estimate hydrodynamic characteristics of wave impact on the ship moored at the berth with a stilling pool. To derive this mathematical model, the analytical method using eigenfunction expansion was employed. Also, the article shows the calculation data to demonstrate the influence of berth characteristics on loads experienced by the ship.

    The prediction of a ship’s resistance especially the viscous wave-making resistance is an important issue in CFD applications. In this paper, the resistances of six ships from hull 1 to hull 6 with different hull forms advancing in still water are numerically studied using the solver naoe-FOAM-SJTU, which was developed based on the open source code package OpenFOAM. Different components of the resistances are computed and compared while considering two speed conditions (12 kn and 16 kn). The resistance of hull 3 is the smallest while that of hull 5 is the largest at the same speed. The results show hull 3 is a good reference for the design of similar ships, which can provide some valuable guidelines for hull form optimization.

  11. A TWO STAGE METHOD FOR BENGALI TEXT EXTRACTION FROM STILL IMAGES CONTAINING TEXT

    2012-07-01

    Full Text Available Bengali text data present in multimedia images having multiple content forms, such as still images and text, contain information that when extracted finds a lot of applications. The images can be of different types, where objects and text may be completely separated or overlapped or embedded in each other. The Bengali text can be of different shapes and sizes. Extraction of text from these types of images becomes challenging because the textual portion has to be correctly separated from the rest of the background. The input image passes through two stages. The first step tries to locate the different components in the image using entropy filtering and the second stage distinguishes the components representing text from the non-textual components based on several features of Bengali text. The text thus obtained from the image can then be used in software such as Bengali OCR for character recognition.

  13. Color segmentation as an aid to white balancing for digital still cameras

    Science.gov (United States)

    Cooper, Ted J.

    2000-12-01

    Digital Still Cameras employ automatic white balance techniques to adjust sensor amplifier gains so that white imaged objects appear white. A color cast detection algorithm is presented that uses histogram and segmentation techniques to select near-neutral objects in the image. Once identified and classified, these objects permit determination of the scene illuminant and implicitly the respective amplifier gains. Under certain circumstances, a scene may contain no near-neutral objects. By using the segmentation operations on non-neutral image objects, memory colors, from skin, sky, and foliage objects, may be identified. If identified, these memory colors provide enough chromatic information to predict the scene illuminant. By combining the approaches from near-neutral objects with those of memory color objects, a reasonable automatic white balance over a wide range of scenes is possible.

  14. Nuclear Winter Revisited: Still the Most Dangerous Potential Environmental Consequence of Human Actions

    Science.gov (United States)

    Robock, A.; Oman, L.; Stenchikov, G.

    2006-12-01

    Twenty years ago, the results of climate model simulations of the response to smoke and dust from a massive nuclear exchange between the superpowers could be summarized as "nuclear winter," with rapid temperature, precipitation, and insolation drops at the surface that would threaten global agriculture. The global nuclear arsenal has fallen by a factor of three since then, but there has been an expansion of the number of nuclear weapons states, with other states trying to develop nuclear arsenals. We use a modern climate model to re- examine the climate response to a range of nuclear wars, producing 5, 50, and 150 Tg of smoke, using tiny, moderate, and large portions of the global arsenal, and find that there would be significant climatic responses to all the scenarios. This is the first time that an atmosphere-ocean general circulation model has been used for such a simulation, and the first time that 10-yr simulations have been conducted. The response to the moderate and large scenarios can still be characterized as nuclear winter, with global catastrophic consequences, but the tiny scenario would still produce climate changes unprecedented in recorded human history. The changes are more long-lasting than previously thought, because the new model, NASA GISS ModelE, is able to represent the atmosphere up to 80 km, and simulates plume rise to the middle and upper stratosphere, producing a long aerosol lifetime. The indirect effects of the use of even a small number of nuclear weapons would have devastating consequences for the planet, and policy responses to the problem of nuclear proliferation need to take into account these environmental effects.

  15. The glazing temperature measurement in solar stills - Errors and implications on performance evaluation

    International Nuclear Information System (INIS)

    Highlights: → We investigate parameters affecting glazing surface temperature measurement accuracy. → Its degradation is mainly attributed to the radiation absorption at the sensor bead. → It is also attributed to poor sensor bond conductance phenomena. → An order of magnitude error is derived from a series of field measurements. → Conditions are specified to minimize error implications on performance evaluations. -- Abstract: Although the brine temperature measurement in solar stills would be more or less conventional, the precise condensing surface temperature measurement, appears to present a significant difficulty to measure. In the present investigation, an analysis is developed aiming to underline the parameters affecting the glazing surface temperature measurement and a series of field measurements are presented, aiming to identify and evaluate the errors associated to the measurement of this crucial physical quantity. It is derived that among other reasons the surface temperature measurement accuracy may strongly be degraded owing to the sensor tip overheating due to the radiation absorption, as well as to the development of poor bond conductance between sensor bead and glazing surface. It may also be degraded owing to the temperature drop across the glazing thickness and the non-uniform temperature distribution over the entire condensing surface area, something that makes the selection of the appropriate location of the particular temperature transducer necessary. Based on the derived measurements, an order of magnitude analysis is employed for the approximate evaluation of error range in the condensing surface temperature measurement. This, which depending on specific conditions was found to vary between about 1 and 2 oC, was employed to demonstrate the implications and approximate conditions under which its effect could become excessively high in ordinary solar still investigations.

    Full Text Available Orientation: In light of the human immunodeficiency virus (HIV pandemic, and in order to improve competitiveness in the South African private sector, many structures have implemented subsidised workplace programmes.Research purpose: The aim of this study was to collect baseline data regarding the knowledge, attitudes, practices and belief (KAPB of employees in the automotive industry in relation to HIV and AIDS, in order to assess the need for HIV and AIDS workplace programmes.Motivation for the study: Given the abundance of HIV and AIDS information, the question is whether these workplace programmes’ efforts are still relevant.Research design, approach and method: A quantitative descriptive study design was used using a self-administered questionnaire covering questions about KAPB with regard to HIV and AIDS. The data collection took place in seven automotive supplier companies in South Africa (n = 733 who were going to implement HIV and AIDS workplace programmes with the support of the Automotive Industry Development Centre in the Eastern Cape.Main findings: High-risk behaviour, as indicated by sexual relations with more than one partner in the last 12 months, occurred in between 12% (management and 42% (cleaners of employees. All risk behaviour indicators showed significant differences (p < 0.05 between management and administrative staff on the one hand and technicians, operators and cleaners on the other. Despite being aware of an HIV policy, more than 50% of employees indicated that they would not be willing to disclose their status.Practical/managerial implications: As HIV and AIDS risk behaviour and stigma remain a problem, HIV infection with associated health problems may threaten productivity in the automotive industry if no measures are taken to address the impact on employees and the company.Contribution: This study strongly supports the conclusion that KAPB studies can still provide important information to tailor HIV workplace

    This experimental study focuses on the effect of pebbles as an energy storage medium on the performance of a solar distillation system. Two single basin solar stills are fabricated with an effective area of 0.5 m2, the glass cover was tilted at 10° with respect to the horizontal. The experiments on the still were carried out under the same climatic conditions for two different modes of operations, (1) conventional still and (2) modified still (pebbles as storage medium). From the study, it could be concluded that (1) the productivity of solar still is increases 9.5 % when pebbles are used as storage medium (2) the maximum amount of heat losses occurs in the solar still is the combined effect of radiation and convection heat transfer from glass to ambient (3) pebbles have the potentiality to store the heat during high solar intensity period and to release the stored energy to water when the solar intensity is low.

    In 2009, we reported an association between low levels of ethyl carbamate (EC) in pot still cachaças from Paraíba State, Brazil, and distillation in copper pot stills equipped with cooled columns. To strengthen these observations, we extended our study to Pernambuco State and assessed 13 pot still and 20 column still cachaça brands. An EC range from distillation apparatus. Maximising distillation reflux ratios in the ascending parts and minimising exposure to copper in the descending parts (through the use of stainless steel) can reduce EC, and also avoid copper contamination.

    A total of 157 hindquarter amputations were carried out in our institution during the last 30 years. We have investigated the reasons why this procedure is still required and the outcome. This operation was used as treatment for 13% of all pelvic bone sarcomas. It was curative in 140 and palliative in 17, usually to relieve pain. There were 90 primary procedures (57%) with the remaining 67 following the failure of previous operations to control the disease locally. The indication for amputation in primary disease was for large tumours for which limb-salvage surgery was no longer feasible. The peri-operative mortality was 1.3% (n = 2) and major complications of wound healing or infection arose in 71 (45%) patients. The survival at five years after hindquarter amputation with the intent to cure was 45%, and at ten years 38%. Local recurrence occurred in 23 patients (15%). Phantom pain was a significant problem, and only 20% used their prosthesis regularly. Functional scores were a mean of 57%. With careful patient selection the oncological results and functional outcomes of hindquarter amputation justify its continued use. PMID:23307686

    Summary: The international fight against the various forms of female circumcision, or the mutilation of the genitals of women and children, has many different aspects. Although no religious text from any religion suggests the practice, still in many countries the torture of young girls and women continue. Even though there is an assumption that the phenomenon is exclusive to the developing world, many practices in the West, such as vaginal and vulvar surgeries, as well as changes to the face and body of women can be included in the same tendency to portray women as impure, incomplete, and in need of improvement so that she can be accepted by prospective husbands.

    Besides its role in bladder and kidney cancer, urology plays a leading part in oncology particularly with regard to prostate cancer, the most frequent malignant tumor found in men. The multitude of hereditary anomalies of the urogenital tract and the resultant medical conditions, the importance of urinary tract infections including the still deadly urosepsis, urolithiasis which has become as widespread a condition as diabetes mellitus, and urinary incontinence as an increasing problem of a continuously aging population play such a large role in routine practice that every practicing physician must acquire the necessary skills for appropriate diagnosis and treatment. Is our current curriculum for training and continuing education adequate for this task?The primary goal of a meaningful program for continuing education must be to impart the corresponding qualities to young colleagues to ensure optimal patient care. The specialist certification exam itself should invariably be based nationwide on an objective written test: the existing European Board of Urology exam would be ideally suited to facilitate a comparison with other countries across Europe.

    The present study develops a multiple-effect diffusion solar still (MEDS) with a bended-plate design in multiple-effect diffusion unit (MDU) to solve the peel-off problem of wick material. The MDU is coupled with a vacuum-tube solar collector to produce a high temperature gradient for high productivity. A heat pipe is used to transfer the solar heat to the MDU. A prototype MEDS-1L was built and tested outdoors. Four performance indexes are proposed for the performance evaluation of MEDS, including daily pure water production per unit area of glass cover, solar absorber, and evaporating surface (Mcov, Msol, Mevp, respectively), and solar distillation efficiency Rcov. The outdoor test results of MEDS-1L show that the solar collector supply temperature Th reaches 100°C at solar radiation 800Wm-2. The highest Mcov is 23.9kgm-2d-1 which is about 29% higher than the basin-type MEDS [11]. The highest value is 25.9kgm-2d-1 for Msol and 2.79kgm-2d-1 for Mevp. The measured Rcov is 1.5-2.44, higher than the basin-type MEDS (1.45-1.88). The Mcov, Msol, Mevp and Rcov of MEDS-1L are all higher than the theoretical calculation of a MEDS with a flat-plate solar collector coupled with a heat pipe (MEDS-FHP) [17].© 2014 Elsevier B.V.

    2010-01-01

    Since the recent results of direct detection experiments at low mass, many authors have revisited the case of light (1 -10) GeV WIMPs. In particular, there have been a few attempts to explain the results from the DAMA/LIBRA, CDMS and/or CoGeNT experiments by invoking neutralinos lighter than 15 GeV. Here we show that in the MSSM, such light particles are completely ruled out by the TEVATRON limits on the mass of the pseudoscalar Higgs. On the contrary, in the NMSSM, we find that light neutralinos could still be viable candidates. In fact, in some cases, they may even have an elastic scattering cross section on nucleons in the range that is needed to explain either the DAMA/LIBRA, CoGeNT or CDMS recent results. Finally, we revisit the lowest limit on the neutralino mass in the MSSM and find that neutralinos should be heavier than ~28 GeV to evade present experimental bounds.

  7. 137Cs activity concentration in wild boar meat may still exceed the permitted levels

    Full Text Available The radiocaesium activity concentration may still remain high in natural products such as game meat, wild mushrooms, and forest berries even more than two decades after the Chernobyl accident. The results of regular control studies of game meat conducted in Poland showed wild boars as the most contaminated game animals. It is well documented that some mushrooms, readily consumed by animals, show high ability to accumulate caesium radioisotopes. Bay bolete, one of the most wide-spread mushroom species in Poland, reveals a unique radiocaesium accumulation feature. Moreover, deer truffle, containing also particularly high levels of radiocaesium, could be another radionu-clide source for wild boars. Furthermore, animals consuming deer truffles could digest contaminated soil components. Among 94 wild boar meat samples analysed in 2008–2009, two exceeded the permitted level. Hence, some precautions should be taken in the population with an elevated intake of wild boar meat. Moreover, since each hunted wild boar is examined for the presence of Trichinella larvae, regular measurements of radiocaesium concentrations in these animals may be advisable for enhancing consumer safety.

  8. Beverage can stay-tabs: still a source for inadvertently ingested foreign bodies in children

    International Nuclear Information System (INIS)

    In the 1970s in part to avoid inadvertent ingestion, the beverage-can industry changed can construction from pull-tabs to the stay-tabs (remain attached to can after opening) used today. Our purpose is to identify the number of inadvertent ingestions of beverage-can stay-tabs by children recognized at our institution. The medical information system of a children's hospital was searched with key terms to identify cases in which a witnessed or self-reported inadvertent ingestion of a beverage-can stay-tab resulted in a radiograph to rule out presence of a foreign body. Demographics, identification of stay-tab on radiographs, associated abnormalities, and patient management were reviewed. Nineteen cases of stay-tab ingestion were identified over 16 years. Mean age of ingesters was 8.5 years with the majority being teenagers and 15 (79%) >5 years of age. The stay-tab could be seen radiographically only in 4 (21%) cases - all with the stay-tab identified in the stomach. The identification of 19 children who inadvertently ingested beverage-can stay-tabs at a single children's hospital suggests that such ingestions still occur. Radiologists should be aware that stay-tabs are radiographically visible in the minority (21%) of cases. (orig.)

  9. The doctrine of providence in the Institutes of Calvin – still relevant?

    Full Text Available In the reformed tradition and theology, the doctrine of provi- dence has always been important and relevant, so much so that it forms an integral part of the reformed confessions. At the same time some of the most difficult theological questions are raised regarding this doctrine, questions like the following: Is God in control of everything? What is the relationship between the providence of God and sin, suffering, man’s responsibility, et cetera? In our times the doctrine as such is questioned or even rejected. What makes this topic even more important is the commemoration of the publication of Darwin’s book, “The origin of species”, coupled with the renewed emphasis on Darwinism, evolutionism and atheism.1 From the perspective of the Calvinistic-reformed theology and in the light of the com- memoration of Calvin’s birth 500 years ago, it is important to determine the relevance of Calvin’s thoughts on a number of important issues in the current debate, e.g. the doctrine on God, providence and creation, sin, suffering, et cetera. It is also determined that Calvin’s thoughts are reflected in the reformed confessions, which is still the living faith of reformed churches all over the world.

    Full Text Available The Kalipunan ng mga Katutubong Mamamayan ng Pilipinas (KAMP or the National Alliance of Indigenous Peoples’ Organization in the Philippines is al- most in their 30 years of existence and yet, like in most cases of indigenous peoples’ issues, there is still no significant number of studies about their role in campaigning for the betterment of the Indigenous Cultural Communities. Anchored on political opportunity structures theory as a guide, the basic motiva- tion of the paper is to illustrate how the KAMP fights and survives through resource mobilization and how the government represented by National Commission on Indigenous Peoples (NCIP and Department of Environment and Natural Resources (DENR accommodate their interests. Using archival research, secondary data analysis, elite interview and participant observation, the paper asserts that KAMP’s use of their organizational structure, advocacy campaigns and political assaults as their basic resources to fight for the Nueva Vizcaya Mining issue are relatively insufficient to a centralist and relatively closed government, despite the presence of democratic institutions. The ability of the Philippine government to strike the balance between development and indigenous peoples’ rights pro- tection shall remain to be a defining feature if not a challenge to the quality of democracy and governance in our land

    Dengue virus and its four serotypes (DENV 1-4) infect approximately 390 million people worldwide each year, with most cases in tropical and subtropical regions. Because of repeated introduction of DENV from epidemic regions and suitable weather conditions, many regions have shifted from hypo-endemicity to hyper-endemicity over recent decades. Since the first dengue outbreak in 1978, it is crucial to understand the current situation in China over nearly 40 years. The purpose of the study was to examine whether dengue in China was endemic or not, which is essential for relevant dengue control and prevention strategy implementation in China. The study, combining epidemiological characteristics of dengue from the disease notification system, phylogenetic and phylogeographic analyses, showed that all four serotypes had been detected in Guangzhou, China, which was dominated by DENV 1-2. The Maximum Likelihood tree analytic results showed that the virus detected in Guangzhou localized in different clades, except of virus of 2002 and 2003 clustered together. There existed the mutual introductions between Guangzhou and Southeast Asia. Most of the viruses were imported from Southeast Asia and the sources of outbreaks in Guangzhou mainly originated from Thailand, Indonesia, and the Philippines. The study indicates that dengue in China still remains as an imported disease, with the possibility of localization. PMID:25772205

    2014-10-01

    The negative health effects of racism have been well documented, but how to intervene to redress these effects has been little studied. This study reports on RISE (Racism Still Exists), a high-risk, high-reward public health intervention that used outdoor advertising to disseminate a "countermarketing" campaign in New York City (NYC). Over 6 months, the campaign advertised stark facts about the persistence of racism in the USA. A probability sample of N = 144 participants from two predominantly Black NYC neighborhoods completed measures of health status, health behaviors, and social attitudes. Three months postintervention, statistically significant declines in psychological distress were seen among study participants who were exposed to the campaign compared to those who were not. There were no changes in other hypothesized outcomes. The campaign also generated significant public discourse, particularly in social media. The results suggest that racism countermarketing campaigns may have promise as a community-based intervention to address health inequalities. PMID:24849616

  13. China’s comparative advantage still in low-tech manufacturing sector

    This paper represents an attempt to estimate the level of vertical specialization in China’s manufacturing industry using China’s input-output tables (1995-2005) compiled by the OECD; describe the trends of evolution in the trade competitiveness of China’s manufacturing industry using the 1995-2006 trade data of 24 Chinese industries; and examine the key factors affecting the trade competitiveness of China’s manufacturing industry in accordance with the analytical framework of Hummels et al (2001). The estimation results indicate that i) the rapid increase in the vertical specialization levels of China’s merchandise sectors (especially the high-tech manufacturing sector) has to some extent explained the explosive growth of China’s exports (especially high-tech exports) in recent years; ii) there have been no substantive changes in China’s comparative advantages. Such advantages are still attributed to the low-tech manufacturing sector. However, the comparative advantage and trade competitiveness of the high-tech manufacturing sector have been on the rise; iii) vertical specialization has signif icantly enhanced the trade competitiveness of China’s manufacturing industry. Foreign market dependence, domestic intermediate input intensity and R&D intensity have an obvious promoting effect on the trade competitiveness of China’s manufacturing industry.

    We investigated the features and the usefulness of gallium scintigraphy in the diagnosis and the assessment of Adult Still's disease (ASD) by retrospective case review. Gallium scintigraphy have been done for 11 cases of ASD (3 males and 8 females) and 4 females were positive. Among these, 67 Ga-citrate was accumulated to the bone marrow in all 4 cases and to the major joints in 2 cases. Positive cases were rather serious and administered more immunosuppressants than negative cases. In order to characterize gallium scintigraphy findings of ASD, i.e. bone marrow accumulation, we analyzed 130 cases of collagen vascular disease. Although 101 cases (77.7%) were positive, only 7 cases (5.4%) showed the accumulation of {sup 67}Ga-citrate to the bone marrow. These include 3 cases with ASD, and 1 case with systemic lupus erythematosus, polyarteritis nodosa, Wegener's granulomatosis and Sjogren's syndrome. We also accumulated 18 patients who exhibited bone marrow accumulation of {sup 69}Ga-citrate, and found that 7 patients had collagen vascular and their related diseases. In conclusion, bone marrow accumulation in gallium scintigraphy is a specific feature of collagen vascular diseases, especially ASD, and it is suggested that cases with positive gallium scintigraphy in ASD can be serious and resistant to treatment.

    On July 10, 1998, the Russian Zenith missile put into an 820-km orbit the Resource-01 no.4 spacecraft together with its five piggyback microsatellites-Safir-2, Westpac, Fasat-Bravo, TMSat, and Gurwin-Techsat. After their separation, a cluster of six satellites was created, revolving around the Earth initially in very close orbits. Almost all the satellites, including the carrier, performed well during the first few years after the launch, but now, after nine years of flight, only the Techsat, designed and built in the Technion-Israel Institute of Technology, that is still operational. A number of experiments, as well as the activities pertaining to the Radio amateur service, were conducted aboard it. The experiments provided a good deal of scientific and technological data, part of which can be considered as a world precedent. A comparison of the Techsat lifetime and performance with those of the microsatellites launched before 2000 makes it evident, that among the small satellites with a versatile experimental program, the Techsat is one of the most successful. Presented here are some of the basic accomplishments of its long-term mission.

Compared with other available dopaminergic therapies, dopamine replacement with LD is associated with the greatest improvement in motor function. Long-term treatment with LD is, however, often complicated by the development of various types of motor response oscillations over the day, as well as drug-induced dyskinesias. Motor fluctuations can be improved by the addition of drugs such as entacapone or monoamine oxidase inhibitors, which extend the half-life of levodopa or dopamine, respectively. However, dyskinesia control still represents a major challenge. As a result, many neurologists have become cautious when prescribing therapy with LD. This review summarizes the available evidence regarding the use of LD to treat PD and will also address the issue of LD delivery as a critical factor for the drug’s propensity to induce motor complications.Keywords: levodopa, motor fluctuations, dyskinesia, Parkinson’s disease

    Vesico-vaginal fistulae (VVF) are still a daily occurrence in Africa. Obstetrical causes are the most frequent. This severe disability requires that everything be implemented to obtain a leak-free closure of the pathological opening. The authors report their experience with 89 cured cases of VVF. Except for 2 cases cured with an abdominal approach, the Moir technique gave good results in 78 cases, for midline, moderate size, fistulae. In 3 instances, closure of the vagina alone was satisfactory. There were 10 recurrences, cured 9 times at the second operation and once at the third. 3 recurrences came from other institutions and were cured after 4 and 5 successive procedures. In 6 instances, for fistulae close to 5 cm or larger and located in areas difficult to reach, the authors have developed a technique of vaginal closure alone using a turned-over, undetermined vaginal flap creating a leak-free diverticulum. No recurrences have been observed with this technique. PMID:2544977

    Full Text Available This paper envisages feminism in a south Asian gender development particularly in Pakistan. Law is the manifestation of principles of justice, equity and good conscience. As’ Gender’ has been taken up in development policy and practices, have been created that have emphasized some aspects of feminist agendas, and pushed others out of the frame. Research paper gives an overview of women in Pakistan are victimized of gender biases begin from the very first institution home. They are facing challenges in claiming their rights of inheritance owing to customary practices, lacunae in the prevailing legal framework and procedure. Patriarchal structure of society, socio-customary practices and discrimination against women are very serious concerns/issues which need to be understood as multidimensional problem. This paper examines the role of feminism on gender development in south Asian perspective especially in Pakistan. Pakistani women seem to have been circumscribed in bounds of religious, cultural and national ideologies as envisioned by the patriarchy of Pakistan. Due to certain cultural, male domination state of affairs the solidarity amongst Pakistani women still distant dream. Current research paper would draw attention to issue mentioned above.

    The mechanism of Stille reactions (cross-coupling of ArX with Ar'SnnBu3 ) performed in the presence of fluoride ions is established. A triple role for fluoride ions is identified from kinetic data on the rate of the reactions of trans-[ArPdBr(PPh3 )2 ] (Ar=Ph, p-(CN)C6 H4 ) with Ar'SnBu3 (Ar'=2-thiophenyl) in the presence of fluoride ions. Fluoride ions promote the rate-determining transmetallation by formation of trans-[ArPdF(PPh3 )2 ], which reacts with Ar'SnBu3 (Ar'=Ph, 2-thiophenyl) at room temperature, in contrast to trans-[ArPdBr(PPh3 )2 ], which is unreactive. However, the concentration ratio [F(-) ]/[Ar'SnBu3 ] must not be too high, because of the formation of unreactive anionic stannate [Ar'Sn(F)Bu3 ](-) . This rationalises the two kinetically antagonistic roles exerted by the fluoride ions that are observed experimentally, and is found to be in agreement with the kinetic law. In addition, fluoride ions promote reductive elimination from trans-[ArPdAr'(PPh3 )2 ] generated in the transmetallation step. PMID:26548772

    Liver transplantation is an important modality of treatment for end-stage liver disease. Liver biopsy evaluation has been an important aspect of the donor evaluation protocol. With the advent of newer modalities of donor evaluation such as high resolution CT scan, fibroscan and NMR spectroscopy, the relevance of the liver biopsy appears to be diminishing. We investigated the usefulness of donor liver biopsy evaluation in patients who had been cleared by radiological investigations. We evaluated 184 donor liver biopsies performed over a one-year period and found that 18% showed >5% steatosis and around 40% showed portal inflammation, which was, however, minimal to mild. Fibrosis was detected in 10 cases (5.4%), 7 being in stage 1 and 3 in stage 2. Donors with these findings were not considered for transplantation. We conclude that the liver biopsy still continues to be relevant especially in a developing country and does add additional information to the diagnostic work-up of a liver donor. PMID:25890612

    Background. There is substantial evidence that the kynurenine pathway (KP) plays a role in the normal physiology of the brain and is involved in the pathology of neurodegenerative disorders such as Huntington's disease and Parkinson's disease (PD). Objective. We set out to investigate the potential roles in PD of single nucleotide polymorphisms (SNPs) from one of the key enzymes of the KP, kynurenine 3-monooxygenase (KMO). Methods. 105 unrelated, clinically definitive PD patients and 131 healthy controls were enrolled to investigate the possible effects of the different alleles of KMO. Fluorescently labeled TaqMan probes were used for allele discrimination. Results. None of the four investigated SNPs proved to be associated with PD or influenced the age at onset of the disease. Conclusions. The genetic link between the KP and PD is still missing. The investigated SNPs presumably do not appear to influence the function of KMO and probably do not contain binding sites for regulatory proteins of relevance in PD. This is the first study to assess the genetic background behind the biochemical alterations of the kynurenine pathway in PD, directing the attention to this previously unexamined field.

    Mining and smelting activities have contaminated the environment with trace metals (TMs) at a worldwide scale for at least two millennia. A combination of chemical approaches and active biomonitoring was performed to analyse the environmental availability and bioavailability of TM palaeo-pollution in a former PbAg mining district in the Vosges Mountains, France. Along a soil TM contamination gradient that covered eight stations, including two archaeological mining sites, the toxicokinetics of six TMs (Pb, Cd, As, Ag, Co, Sb) in the snail Cantareus aspersus revealed that palaeo-pollution from the studied sites remains bioavailable. This study provides the first data on the accumulation kinetics of Ag and Co for C. aspersus. The environmental availability of the TMs was estimated with three chemical extraction methods (aqua regia, EDTA 50 mM, CaCl2 10 mM). Univariate regression analyses showed that EDTA extraction is the best method for estimating the bioavailability of Pb, As, Ag, Co and Sb to snails. None of the three extractants was efficient for Cd. A multivariate analysis of bioaccumulation data revealed that TM bioavailability and transfer were modulated by exposure sources (soil, humus and vegetation) rather than by soil physico-chemical characteristics. Hence, although the deposition of mining wastes dates back several centuries, these wastes still represent a source of contamination that must be considered to develop relevant site management and environmental risk assessment.

    Full Text Available In the case of Oliveira’s Doomed Love (Amor de Perdição, 1978 (an adaptation of the homonymous classic Portuguese novel, Bresson’s model theory provides an adequate theoretical model for a melodrama in which characters, ‘hit by fate,’ are following their destinies as if ‘under hypnosis.’ Besides a typically frontal, iconic representation of bodies thoroughly framed by windows, doors, and mirrors, in this and many other films by Oliveira, the intermedial figure of tableau vivant also reveals the movement-stillness mechanisms of the medium of film by turning, under our eyes, the body into a picture. His Abraham’s Valley (Vale Abraão, 1993 is also relevant for a fetishistic representation of (female feet and legs. This visual detail, somewhat reminding of Buñuel’s similar obsession, is not only subversive in terms of representation of socio-cultural taboos, but is also providing a compelling sensual experience of both the body and the medium.

    OBJECTIVE: We aim to determine if urine cytology was still necessary as a routine part of the evaluation for the presence of urological malignancy and to evaluate its cost effectiveness. METHODS: Urine cytology reports over a 6-year period (2000-2005) were retrieved from our institution\\'s pathology department database. Patients with urine cytology positive for malignant cells were identified. We retrospectively reviewed the charts of these patients for age, sex, flexible cystoscopy and radiological imaging results. The cost of urine cytology was retrieved from the pathology department. RESULTS: There were a total of 2,568 urine cytological examinations. Of these, 25 were positive for malignant cells. There were 19 male (76%) and 6 female (24%) patients with a mean age of 72 years (range: 49-97). In 21 patients with positive cytology, a bladder tumor was identified at flexible cystoscopy and\\/or imaging studies. For a positive cytology yield of 1%, EUR 210,000 was spent. CONCLUSIONS: Routine urine cytology was not cost effective and did not add to the diagnostic yield beyond cystoscopy and diagnostic imaging. It may be omitted in the initial evaluation of urological malignancy.

  5. Exploration into 1990s will still be shaped by politics, economics

    Frontier exploration plays continue to yield sizable oil and gas discoveries, despite recent wide fluctuations in the price of crude that have altered exploration budgets and curtailed activity. Amauligak in Canada, Colombia's Cano Limon, Albacora and Marlim in Brazil, the Haltenbank prospects offshore Norway, North Yemen's Alif field, and lagifu in Papua New Guinea are all examples of the occasional reward of a giant field. With a stable oil price of between $15-18/bbl during 1987, international exploration levels will slowly recover. And it is likely that an average $18/bbl price for the year will be sufficient to put a number of deferred development projects back on track. Activity levels will still vary widely from region to region and country to country however, controlled by political as well as economic conditions. Exploration was hit especially hard in the U.S., where finding and development costs are high. Operators continued to spend a greater share of their exploration funds outside the U.S. in 1987.

    Full Text Available Remains of the highly nutritious aquatic plant Fox nut – Euryale ferox Salisb. (Nymphaeaceae – were found at the Acheulian site of Gesher Benot Ya'aqov, Israel. Here, we present new evidence for complex cognitive strategies of hominins as seen in their exploitation of E. ferox nuts. We draw on excavated data and on parallels observed in traditional collecting and processing practices from Bihar, India. We suggest that during the early Middle Pleistocene, hominins implemented multistage procedures comprising underwater gathering and subsequent processing (drying, roasting and popping of E. ferox nuts. Hierarchical processing strategies are observed in the Acheulian lithic reduction sequences and butchering of game at this and other sites, but are poorly understood as regards the exploitation of aquatic plant resources. We highlight the ability of Acheulian hominins to resolve issues related to underwater gathering of E. ferox nuts during the plant's life cycle and to adopt strategies to enhance their nutritive value.

  7. RAPD-PCR – still a suitable Method for Genetically Underexplored Species?

    Full Text Available Saithe (Pollachius virens is a commercially important fish species; the annual catch quota in the Northeast Atlantic exceeds 100.000 t. Despite that saithe is underexplored from a fish population genetically view. Because saithe is a highly migratory species, which undergoes a long larval drift, the population structure of saithe within the Northeast Atlantic is not fully understood. Models used as a basis for the management plan are based on tagging studies, which have been carried out in the 1960th. But still there are doubts regarding the numbers of stocks living in the Northeast Atlantic. Migration routes are affected by salmon farming, growing steadily from the 1990th. In the last years a hyperstability of the saithe stock in the North Sea had been detected underlining the need to have a closer look on the saithe stocks in the Northeast Atlantic. Random amplified polymorphic DNA (RAPD - PCR is a DNA fingerprinting technique often used in species identification and population genetic research for species, whose genome has not been sequenced very extensive as being the case for most of the food fishes. We applied RAPD-PCR in a study of saithe populations from the North Atlantic. The suitability of RAPD-PCR was improved by optimisations for enhanced reproducibility. The “classical” protocol for RAPD-PCR was modified by increasing the annealing temperature and shortening the time of annealing, providing a much better reproducibility. Thus, RAPD-PCR was found to be a straightforward and low-cost way, compared to other population genetic tools, to get a first insight into the population structure of less sequenced fish species within a very short time, being useful for preliminary studies or laboratories without large capacities for DNA sequencing.

    Full Text Available Background: Chronic kidney disease (CKD has become a public health problem in Nigeria. Efforts are being geared toward early diagnosis and prevention of CKD. This study involved the evaluation of the referral pattern and mode of presentation of CKD patients at first contact in a tertiary health institution. Patients and Methods: Patients′ records over an 18 month period were retrieved and the following information extracted: Sociodemographic data, referral hospital, mode of presentation, etiology of CKD, packed cell volume, blood pressure, and estimated glomerular filtration rate (GFR at first presentation. Results: There were 202 CKD patients with a male: female ratio of 1.7:1 and a mean age of 48.15 ± 16.69 years. The median estimated GFR of the patients at presentation was 3.17 ml/min/1.73 m [2] . The common etiologies of CKD were chronic glomerulonephritis, hypertension, diabetes mellitus, obstructive nephropathy in 69 (34.2%, 47 (23.3%, 38 (18.8%, and 21 (10.4% respectively. Among these patients, 111 (55% and 98 (48.6% had moderate to severe hypertension and anemia, respectively, 173 (85.6% presented in CKD Stage 5, 101 (50% required urgent hemodialysis whereas 123 (60.9% required in-hospital admission. Only (18 9% of these CKD patients presented by self-referral while (103 51% were referred from secondary and private health facilities. Conclusion: Most Nigerian CKD patients still present very late to nephrologists implying that the present preventive strategies have not yielded desired results. Early diagnosis and referral of CKD patients could be better achieved through regular education of the public and retraining of health workers especially those in primary and secondary health institutions.

    Full Text Available Background: Pleural fluid cytology for malignant cells is the easiest way to diagnose malignant pleural effusion with good sensitivity and specificity. With the introduction of medical thoracoscopy, the use of closed pleural biopsy for the diagnosis of cytology negative malignant pleural effusion is gradually decreasing. However use of thoracoscopy is limited due to its high cost and procedure related complications. Aims: The aim was to assess the usefulness of closed pleural biopsy in the diagnosis of malignant pleural effusion. Materials and Methods: Sixty-six patients of pleural effusion associated with malignancy were selected from the patients admitted in the chest ward of a tertiary care hospital over a period of 1 year. Pleural fluid aspiration for cytology and closed pleural biopsy were done in all the patients. Results: Out of 66 patients, 46 (69% patients showed malignant cells in pleural fluid cytology examination. Cytology was positive in 35 (52%, 10 (15%, and 1 (1.5% patients in the first, second, and third samples respectively. Closed pleural biopsy was positive in 32 (48% patients. Among them, 22 also had positive cytology. Additional 10 cytology negative patients were diagnosed by pleural biopsy. Cytology-histology concordance was seen in 12 patients. Definite histological diagnosis could be achieved in five patients with indeterminate cytology. Pleural biopsy was not associated with any major postoperative complication. Conclusion: Closed pleural biopsy can improve the diagnostic ability in cytology negative malignant pleural effusion. Closed pleural biopsy has still a place in evaluation of malignant pleural effusion especially in a resource-limited country like India.

  10. Nuclear winter revisited with a modern climate model and current nuclear arsenals: Still catastrophic consequences

    Twenty years ago, the results of climate model simulations of the response to smoke and dust from a massive nuclear exchange between the superpowers could be summarized as "nuclear winter," with rapid temperature, precipitation, and insolation drops at the surface that would threaten global agriculture for at least a year. The global nuclear arsenal has fallen by a factor of three since then, but there has been an expansion of the number of nuclear weapons states, with additional states trying to develop nuclear arsenals. We use a modern climate model to reexamine the climate response to a range of nuclear wars, producing 50 and 150 Tg of smoke, using moderate and large portions of the current global arsenal, and find that there would be significant climatic responses to all the scenarios. This is the first time that an atmosphere-ocean general circulation model has been used for such a simulation and the first time that 10-year simulations have been conducted. The response to the 150 Tg scenario can still be characterized as "nuclear winter," but both produce global catastrophic consequences. The changes are more long-lasting than previously thought, however, because the new model, National Aeronautics and Space Administration Goddard Institute for Space Studies ModelE, is able to represent the atmosphere up to 80 km, and simulates plume rise to the middle and upper stratosphere, producing a long aerosol lifetime. The indirect effects of nuclear weapons would have devastating consequences for the planet, and continued nuclear arsenal reductions will be needed before the threat of nuclear winter is removed from the Earth.

    Full Text Available One of the most important moments of the start or restart of the academic activity has always been the opening of courses in each subject (discipline that would be studied. On these occasions each professor shows to the students the subject of the discipline, place and role that intellectual seizure of that object in the formation of their professional competence required by the exigencies of the time. Most teachers stop on the most important sources, sources of knowledge that young learners can turn to and would be better to turn. They indicate written sources, books, magazines and other publications available in classical libraries and add, especially now, the world’s largest library: the Internet. However, teachers advise students to seek permanently another source, a "book" - permanently opened, the book of reality that contains the most truth and what is very important - many problems waiting to be discovered and resolved. Leafing over "the first pages" of one of the "volumes" of this huge established "book", I found that the paradigm "Everything moves. Nothing stands still" as the paradigm "movement is absolute, and the repose - roughly" is far from having exhausted full knowledge of "everything". But knowledge can enrich through investigation of the unknown aspects. Substantially reducing the size of the unknown we have subscribed to communicate, stopping on several sides and objectives of the issues: Further examination of the main contents of the concept of development; Nominate a limited number of forms of movement in the "kingdom" of the Megasystem Eco-soc-eco; Further investigation of the causes of motion; Pace to and rhythm in which the different forms of movement develop; Which are the directions in which evolve different directions of movement forms.

  12. KENNEDY, KENNEDY, AND THE EIGHTH AMENDMENT: “STILL IN SEARCH OF A UNIFYING PRINCIPLE”?

    Full Text Available In Kennedy v. Louisiana, the United States Supreme Court held unconstitutional a state law that provided for the imposition of death upon one convicted of raping, but not killing or attempting to kill, a child. Justice Anthony Kennedy wrote the opinion for the Court, in which the majority, employing various analytical tools, brought its "own judgment" to bear on the excessiveness, and therefore the constitutionality, of the death sentence under the Eighth Amendment's Cruel and Unusual Punishments Clause. In emphasizing the Court's use of its own judgment in making the determination of excessiveness or disproportionality, Justice Kennedy and the majority risked the same public and internal dissenting Court criticisms that accompanied previous death penalty opinions in which Court majorities and pluralities similarly employed their own judgments. In the sharp divide over these issues, critics have accused those jurists of disguising their personal views of morality as the doctrinal application of their "own judgment" on these questions. This article argues that despite the criticisms and despite the Court's statement that at least some of its capital punishment case law is "still in search of a unifying principle," there is a precedential thread unifying and justifying the Court's own assessment of excessiveness under the Eighth Amendment. Historical analysis of the Court's Eighth Amendment statements shows that the clear thread in the cases is respect for human dignity and restraint, which plays out through the Amendment's proportionality guarantee. The Court's application of that guarantee against excessiveness has, time and again, invoked the Court's own judgment, based on  contemporary knowledge of punishment, of punishment's goals, and about decency in punishment. This article argues that that approach is sound and historically rooted, and that the Court should continue to apply its own judgment about decency, excessiveness, and

    In 1982 the primary technology of disseminating educational information was the printed book and the typewriter with the mimeograph machine. In 2012, the world wide web, interactive books, and social media are major players in educational technology. Students have moved from passive reading and listening to constructing their own knowledge. In 1982, the paradigm in science education included exploring the common interests of science and education, the role of formal and informal education, and the importance of providing scientists for the workforce. In 2012, conversations have broadened to include topics of citizen science, stakeholder involvement, and risk communication to policy makers and communities. As the population of Earth has grown from over 4.5 billion people to over 7 billion people in the same time period, the role of science education has expanded to global concerns. The Asia Pacific region bears a significant proportion of the world's population and high risks associated with natural hazards and with climate change. Educational conversations include how science impacts and informs public policy, community empowerment, and collaborations among the various types of groups which can affect change. These organizations include scientific research and educational institutions,; non-governmental organizations (NGOs); educators in schools, museums and science centers; and government officials from local to national levels. There is considerable interest in bridging disciplines that impact the populations at risk, i.e. education, development, disaster risk management, public communication, and others. Despite the broadening of concerns, changes in technology, and the ways people get information, education still focuses on some basic issues that have not changed. Some of these include interesting young people in STEM study and careers, providing messages that are clearly understood, trying to understand nature of working across disciplines, and involving the

  15. Is the Greulich and Pyle atlas still valid for Dutch Caucasian children today?

    International Nuclear Information System (INIS)

    Background: In our Paediatric Radiology Department, the Greulich and Pyle technique is used to assess skeletal age. Several authors have raised questions with regard to the applicability of this technique in a contemporary paediatric and adolescent population. Objective: To compare skeletal age and calendar age in a healthy Dutch Caucasian population in order to test the applicability in this specific population. Materials and methods: For this study we enrolled 278 Dutch Caucasian boys (age range 5.0-19.5 years, mean 12.6 years) and 294 Dutch Caucasian girls (age range 5.2-19.9 years, mean 12.2 years). Radiographs of the left hand were scored according to the Greulich and Pyle atlas by two investigators. Results: Intra-observer coefficient of variation of duplicate assessment of skeletal age for investigator 1 (resident) was 2.4 % and for investigator 2 (radiologist) was 1.5 %. We found no significant systematic differences between the two observers regarding variability and levels of measurement, and the agreement was good. There was a strongly significant correlation between skeletal and calendar age rgirls = 0.974 and rboys = 0.979 (P < 0.001). On average, calendar age preceded skeletal age by a small amount (1.7 months in girls and 3.3 months in boys, both P < 0.001). Conclusions: The reliability of the Greulich and Pyle atlas in our study corresponds well with previously reported studies. Based on our data, we conclude that the Greulich and Pyle atlas is still applicable in Dutch Caucasian children and adolescents. (orig.)

    These TOPEX/Poseidon data, collected over the latest 10-day sampling cycle, March 1 to 11, 2000, show the La Nina condition still exists. The image of sea surface heights reflects unusual patterns of heat storage in the ocean. Sea-surface height is shown relative to normal height (green). The cooler water (blue and purple) measures between 8 and 24 centimeters (3 and 9 inches) lower than normal. The giant horseshoe of warmer water (red and white) continues to dominate the western Pacific with higher than normal sea-surface heights between 8 and 24 centimeters (3 and 9 inches).This view of the oceans from TOPEX/Poseidon is an input to the National Oceanic and Atmospheric Administration (NOAA) seasonal forecasts. The impacts of current ocean conditions in the Pacific for spring in the U.S., according to Dr. Ants Leetmaa, director of NOAA's Climate Prediction Center, imply drier than normal conditions for much of the southern half of the U.S. Leetmaa says the conditions also indicate above-normal rainfall in the Pacific northwest, and a warmer than normal U.S., except for the west coast where spring conditions will be near normal.Scientists continue to debate whether this image hints at the presence of a large, longer lasting climate pattern, the Pacific Decadal Oscillation. This long-term pattern that covers most of the Pacific Ocean has significant implications for global climate, especially over North America.The U.S.-French TOPEX/Poseidon mission is managed JPL for the NASA's Earth Science Enterprise, Washington, D.C.

    Background: Computed tomographic angiography has become the standard evaluating method of potential living renal donors in most centers. Although incidence of fibromuscular dysplasia is low (3.5-6%), this pathology may be relevant for success of renal transplantation. The incidence of FMD in our population of LRD and reliability of CTA for detecting vascular pathology were the aims of this study. Materials and methods: 101 living renal donors, examined between 7/2004 and 9/2008 by CTA, were included in a retrospective evaluation. The examinations were carried out using a 64 Multi-detector CT (Siemens Medical Solutions, Erlangen). The presence or absence of the characteristic signs of fibromuscular dysplasia, as 'string-of-beads' appearance, focal stenosis or aneurysms, were assessed and graded from mild (=1) to severe (=3). Furthermore, vascular anatomy and arterial stenosis were investigated in this study. Retrospective analysis of CTA and ultrasound were compared with operative and histological reports. Results: Four cases of fibromuscular dysplasia (incidence 3.9%) in 101 renal donors were diagnosed by transplanting surgeons and histopathology, respectively. Three cases could be detected by CTA. In one donor even retrospective analysis of CTA was negative. Ten accessory arteries, 14 venous anomalies and 12 renal arteries stenosis due to atherosclerosis were diagnosed by CTA and could be confirmed by the operative report. Conclusion: CTA is sufficient for detection of hemodynamic relevant stenosis and vascular anatomy. Only one patient with a mild form of FMD was under estimated. Therefore, if the CTA shows slightest irregularities which are not typical for atherosclerotic lesions, further diagnostic work up by DSA might still be necessary.

  19. Astrocytes Surviving Severe Stress Can Still Protect Neighboring Neurons from Proteotoxic Injury.

    Astrocytes are one of the major cell types to combat cellular stress and protect neighboring neurons from injury. In order to fulfill this important role, astrocytes must sense and respond to toxic stimuli, perhaps including stimuli that are severely stressful and kill some of the astrocytes. The present study demonstrates that primary astrocytes that managed to survive severe proteotoxic stress were protected against subsequent challenges. These findings suggest that the phenomenon of preconditioning or tolerance can be extended from mild to severe stress for this cell type. Astrocytic stress adaptation lasted at least 96 h, the longest interval tested. Heat shock protein 70 (Hsp70) was raised in stressed astrocytes, but inhibition of neither Hsp70 nor Hsp32 activity abolished their resistance against a second proteotoxic challenge. Only inhibition of glutathione synthesis abolished astrocytic stress adaptation, consistent with our previous report. Primary neurons were plated upon previously stressed astrocytes, and the cocultures were then exposed to another proteotoxic challenge. Severely stressed astrocytes were still able to protect neighboring neurons against this injury, and the protection was unexpectedly independent of glutathione synthesis. Stressed astrocytes were even able to protect neurons after simultaneous application of proteasome and Hsp70 inhibitors, which otherwise elicited synergistic, severe loss of neurons when applied together. Astrocyte-induced neuroprotection against proteotoxicity was not elicited with astrocyte-conditioned media, suggesting that physical cell-to-cell contacts may be essential. These findings suggest that astrocytes may adapt to severe stress so that they can continue to protect neighboring cell types from profound injury. PMID:26374549

  20. Contrast-enhanced MR angiography of abdominal vessels: Is there still a role for angiography?

    The purpose of this review article is to describe recent advantages in contrast-enhanced (CE) three-dimensional (3D) magnetic resonance angiography (MRA) in comparison with other vascular imaging techniques, and to discuss their current clinical applications for the imaging of abdominal vessels. Principles and technical considerations are presented and clinical applications are reviewed for different vascular diseases. In ruptured aortic aneurysms and acute dissections CT is the method of first choice. Contrast-enhanced 3D MRA can be well used for therapeutic planning and follow-up in patients with stable disease. A comprehensive MR examination including CE 3D MRA, MR urography and MR nephrogram has the potential to replace the conventional studies for the evaluation of renal vascular disease. It is an accurate method for imaging the origins of coeliac and superior mesenteric arteries, although the image resolution is too low for reliable assessment of the inferior mesenteric artery. Contrast-enhanced 3D MRA has emerged as the method of choice for studying the portal venous system in liver transplant recipients, in patients with portal hypertension and in cases with abdominal tumours for preoperative evaluation. Additional non-invasive flow measurements are useful in monitoring portal hypertension. The abdominal veins can be well imaged using unenhanced MR techniques. Imaging may be facilitated with intravascular contrast media. Contrast-enhanced 3D MRA can replace intra-arterial DSA for diagnosis, therapy planning and follow-up in patients with abdominal vascular disease. Catheter-based arteriography will still be used for interventional procedures such as percutaneous transluminal angioplasty, stent placement and embolisation. (orig.)
