  1. Popper's Thought Experiment Reinvestigated

    Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

  2. Thought experiment with tritium

    An experiment is proposed in which a minimum of thirty (30) grams of tritium is packaged as lithium tritide in a steel container weighing several kilograms. After decontamination of the outside surface, calorimetry measurements would be made, and the unit would be weighed very accurately. After several decades, the calorimeter and weight measurements would be repeated. If the weight measurements could be made with the required accuracy, it would be possible to correlate the observed change in mass with the total energy emitted (calculated from the mean energy measured by calorimetry) over the time interval. If successful, this experiment would, in the opinion of the authors, be the first laboratory experiment to directly verify the equivalency of mass and energy. 4 refs., 2 figs., 3 tabs

    The aim of these experiments is to search for several rare-decay modes of the muon and the pion and to study these decay modes should they be observed. In Exps. 400/445, the muon-number-nonconserving decays μ + αe + e + e - , μ + →e + γ, and μ + →e + γγ are being sought with a sensitivity to branching ratios of about 10 -11 relative to ordinary muon decay. Experiment 726 will search for the charge-conjugation-violating decay π 0 →3γ with a sensitivity to a branching ratio as small as 10 -9 relative to ordinary π 0 decay. Experiment 888 is a study of radiative pion decay π + →e + nu/sub e/γ

    Let n>=2 be identical rockets: R1 ,R2 , ..., Rn. Each of them moving at constant different velocities respectively v1, v2, ..., vn on parallel directions in the same sense. In each rocket there is a light clock, the observer on earth also has a light clock. All n + 1 light clocks are identical and synchronized. The proper time Δt' in each rocket is the same. Let's focus on two arbitrary rockets Ri and Rjfrom the previous n rockets. Let's suppose, without loss of generality, that their speeds verify virocket Rj is contracted with the factor C(vj -vi) , i.e. Lj =Lj' C(vj -vi) .(2) But in the reference frame of the astronaut in Rjit is like rocket Rjis stationary andRi moves with the speed vj -vi in opposite direction. Therefore, similarly, the non-proper time interval as measured by the astronaut inRj with respect to the event inRi is dilated with the same factor D(vj -vi) , i.e. Δtj . i = Δt' D(vj -vi) , and rocketRi is contracted with the factor C(vj -vi) , i.e. Li =Li' C(vj -vi) .But it is a contradiction to have time dilations in both rockets. (3) Varying i, j in {1, 2, ..., n} in this Thought Experiment we get again other multiple contradictions about time dilations. Similarly about length contractions, because we get for a rocket Rj, n-2 different length contraction factors: C(vj -v1) , C(vj -v2) , ..., C(vj -vj - 1) , C(vj -vj + 1) , ..., C(vj -vn) simultaneously! Which is abnormal.

  5. A Lithium Vapor Box Divertor Similarity Experiment

    2017-10-01

    A lithium vapor box divertor offers an alternate means of managing the extreme power density of divertor plasmas by leveraging gaseous lithium to volumetrically extract power. The vapor box divertor is a baffled slot with liquid lithium coated walls held at temperatures which increase toward the divertor floor. The resulting vapor pressure differential drives gaseous lithium from hotter chambers into cooler ones, where the lithium condenses and returns. A similarity experiment was devised to investigate the advantages offered by a vapor box divertor design. We discuss the design, construction, and early findings of the vapor box divertor experiment including vapor can construction, power transfer calculations, joint integrity tests, and thermocouple data logging. Heat redistribution of an incident plasma-based heat flux from a typical linear plasma device is also presented.

    In 1930, Einstein argued against the consistency of the time-energy uncertainty relation by discussing a thought experiment involving a measurement of the mass of the box which emitted a photon. Bohr seemingly prevailed over Einstein by arguing that Einstein's own general theory of relativity saves the consistency of quantum mechanics. We revisit…

    Jay Orear, in his introductory physics text, defined the weight of a person as the reading one gets when standing on a (properly calibrated) bathroom scale.

    We describe a thought experiment using an isolated system of known parameters and assuming the correctness of Clausius and Boltzmann descriptions of entropy. The experiment produced an astronomical increase in the number of possible ways the system can be arranged and inescapably in achieving this, an increase in the compartment volume of the system. The result may possibly be of significance to cosmology.

  9. Thought Speed, Mood, and the Experience of Mental Motion.

    Science.gov (United States)

    Pronin, Emily; Jacobs, Elana

    2008-11-01

    This article presents a theoretical account relating thought speed to mood and psychological experience. Thought sequences that occur at a fast speed generally induce more positive affect than do those that occur slowly. Thought speed constitutes one aspect of mental motion. Another aspect involves thought variability, or the degree to which thoughts in a sequence either vary widely from or revolve closely around a theme. Thought sequences possessing more motion (occurring fast and varying widely) generally produce more positive affect than do sequences possessing little motion (occurring slowly and repetitively). When speed and variability oppose each other, such that one is low and the other is high, predictable psychological states also emerge. For example, whereas slow, repetitive thinking can prompt dejection, fast, repetitive thinking can prompt anxiety. This distinction is related to the fact that fast thinking involves greater actual and felt energy than slow thinking does. Effects of mental motion occur independent of the specific content of thought. Their consequences for mood and energy hold psychotherapeutic relevance. © 2008 Association for Psychological Science.

    Full Text Available The purpose of the current study is to discuss thought with extension of thinking, one of the main concepts of philosophy education, on the basis of analytical philosophy and philosophy of decomposition and to explain its importance for chemistry. From elementary school to university, experiments to be conducted by students in chemistry laboratories are given them like recipes and they are asked to make their experiments according to these recipes. In fact, by using the thinking style imparted to students in class, they must design an experiment and through the practical thinking skills they have gained again in the class, they must conduct the experiment according to this design. Therefore, understanding thought and thinking in relation to chemistry education is of great importance. In the methodology of the current study, holistic approach was adopted. Descriptive survey method was used and document analysis was conducted. In the study, the difference between the concepts of thought and thinking and personal and socio-cultural factors and concepts giving rise to their emergence and their uniqueness and importance were evaluated. As a result, the conditions in which the instruction about the concept of thinking could be integrated into chemistry education were discussed. Finally, the conditions of thinking instruction to students and teachers was explained and contribution of thinking instruction to students and teachers was given.

  11. Gas box control system for Tandem Mirror Experiment-Upgrade

    Bell, H.H. Jr.; Hunt, A.L.; Clower, C.A. Jr.

    1983-01-01

    The Tandem Mirror Experiment-Upgrade (TMX-U) uses several methods to feed gas (usually deuterium) at different energies into the plasma region of the machine. One is an arrangement of eight high-speed piezo-electric valves mounted on special manifolds (gas box) that feed cold gas directly to the plasma. This paper describes the electronic valve control and data acquisition portions of the gas box, which are controlled by a desk-top computer. Various flow profiles have been developed and stored in the control computer for ready access by the operator. The system uses two modes of operation, one that exercises and characterizes the valves and one that operates the valves with the rest of the experiment. Both the valve control signals and the pressure transducers data are recorded on the diagnostics computer so that they are available for experiment analysis

    There are many benchmark experiments carried out so far with DT neutrons especially aiming at fusion reactor development. These integral experiments seemed vaguely to validate the nuclear data below 14 MeV. However, no precise studies exist now. The author's group thus started to examine how well benchmark experiments with DT neutrons can play a benchmarking role for energies below 14 MeV. Recently, as a next phase, to generalize the above discussion, the energy range was expanded to the entire region. In this study, thought experiments with finer energy bins have thus been conducted to discuss how to generally estimate performance of benchmark experiments. As a result of thought experiments with a point detector, the sensitivity for a discrepancy appearing in the benchmark analysis is "equally" due not only to contribution directly conveyed to the deterctor, but also due to indirect contribution of neutrons (named (A)) making neutrons conveying the contribution, indirect controbution of neutrons (B) making the neutrons (A) and so on. From this concept, it would become clear from a sensitivity analysis in advance how well and which energy nuclear data could be benchmarked with a benchmark experiment.

  14. Monte Carlo simulation experiments on box-type radon dosimeter

    2014-01-01

    Epidemiological studies show that inhalation of radon gas ( 222 Rn) may be carcinogenic especially to mine workers, people living in closed indoor energy conserved environments and underground dwellers. It is, therefore, of paramount importance to measure the 222 Rn concentrations (Bq/m 3 ) in indoors environments. For this purpose, box-type passive radon dosimeters employing ion track detector like CR-39 are widely used. Fraction of the number of radon alphas emitted in the volume of the box type dosimeter resulting in latent track formation on CR-39 is the latent track registration efficiency. Latent track registration efficiency is ultimately required to evaluate the radon concentration which consequently determines the effective dose and the radiological hazards. In this research, Monte Carlo simulation experiments were carried out to study the alpha latent track registration efficiency for box type radon dosimeter as a function of dosimeter’s dimensions and range of alpha particles in air. Two different self developed Monte Carlo simulation techniques were employed namely: (a) Surface ratio (SURA) method and (b) Ray hitting (RAHI) method. Monte Carlo simulation experiments revealed that there are two types of efficiencies i.e. intrinsic efficiency (η int ) and alpha hit efficiency (η hit ). The η int depends upon only on the dimensions of the dosimeter and η hit depends both upon dimensions of the dosimeter and range of the alpha particles. The total latent track registration efficiency is the product of both intrinsic and hit efficiencies. It has been concluded that if diagonal length of box type dosimeter is kept smaller than the range of alpha particle then hit efficiency is achieved as 100%. Nevertheless the intrinsic efficiency keeps playing its role. The Monte Carlo simulation experimental results have been found helpful to understand the intricate track registration mechanisms in the box type dosimeter. This paper explains that how radon

    The Bohr-Einstein photon box thought experiment is a forerunner of the EPR experiment: a packet of radiation escapes from a box, and the box-plus-radiation state remains entangled. Hence, a measurement on the box makes a difference for the state of the far-away radiation long after its escape. This

  17. A Thought Experiment Comparing Austrian and Keynesian Stimulus Packages

    Directory of Open Access Journals (Sweden)

    Wladimir Kraus

    Full Text Available Essentially, there are two competing views of how to overcome an economy-wide recession/depression. The Austrian view understands the free-play of competition as the most potent means to overcome the short-run mismatch between an excessive boom-level of nominal wages/prices and depressed crisis-level volume of aggregate spending. In the Keynesian view, the disastrous mismatch between desired saving and planned investment inherent in capitalist economies requires the government to step in and take up the burden of spending to infuse the lacking demand for products and labor.The thought experiment presented in the paper is designed to provide the reader with a direct comparison of major analytical claims of the two competing approaches to assess the ability of each of the two to affect, positively or negatively, employment, capital accumulation, and the general standard of living/real wages.

  18. Studying scientific thought experiments in their context: Albert Einstein and electromagnetic induction

    Science.gov (United States)

    Potters, Jan; Leuridan, Bert

    2017-05-01

    This article concerns the way in which philosophers study the epistemology of scientific thought experiments. Starting with a general overview of the main contemporary philosophical accounts, we will first argue that two implicit assumptions are present therein: first, that the epistemology of scientific thought experiments is solely concerned with factual knowledge of the world; and second, that philosophers should account for this in terms of the way in which individuals in general contemplate these thought experiments in thought. Our goal is to evaluate these assumptions and their implications using a particular case study: Albert Einstein's magnet-conductor thought experiment. We will argue that an analysis of this thought experiment based on these assumptions - as John Norton (1991) provides - is, in a sense, both misguided (the thought experiment by itself did not lead Einstein to factual knowledge of the world) and too narrow (to understand the thought experiment's epistemology, its historical context should also be taken into account explicitly). Based on this evaluation we propose an alternative philosophical approach to the epistemology of scientific thought experiments which is more encompassing while preserving what is of value in the dominant view.

    Thought Experiments of Economic Surplus: Science and Economy in Ernst Mach's Epistemology. Thought experiments are an important element in Ernst Mach's epistemology: They facilitate amplifying our knowledge by experimenting with thoughts; they thus exceed the empirical experience and suspend the quest for immediate utility. In an economical perspective, Mach suggested that thought experiments depended on the production of an economic surplus based on the division of labor relieving the struggle for survival of the individual. Thus, as frequently emphasized, in Mach's epistemology, not only the 'economy of thought' is an important feature; instead, also the socioeconomic conditions of science play a decisive role. The paper discusses the mental and social economic aspects of experimental thinking in Mach's epistemology and examines those within the contemporary evolutionary, physiological, and economic contexts. © 2015 WILEY-VCH Verlag GmbH & Co.

    Two-dimensional models for biological clogging and sorptive tracer transport were used to study the progress of clogging in a sand box experiment. The sand box had been inoculated with a strip of bacteria and exposed to a continuous injection of nitrate and acetate. Brilliant Blue was regularly...... injected during the clogging experiment and digital images of the tracer movement had been converted to concentration maps using an image analysis. The calibration of the models to the Brilliant Blue observations shows that Brilliant Blue has a solid biomass dependent sorption that is not compliant...... with the assumed linear constant Kd behaviour. It is demonstrated that the dimensionality of sand box experiments in comparison to column experiments results in a much lower reduction in hydraulic conductivity Žfactor of 100. and that the bulk hydraulic conductivity of the sand box decreased only slightly. However...

  1. Understanding Community: thoughts and experiences of young people

    Directory of Open Access Journals (Sweden)

    Hilary Yerbury

    2009-08-01

    Full Text Available This ethnographic study of members of Generation X and Generation Y seeks to explore the ways they understand and experience community. Their comments and stories were gathered through interviews collected towards the end of 2006 and the early part of 2007. These provide richly textured evidence of their need to belong, to maintain everyday relationships and to collaborate with others at the same time as they commodify relationships or share information but not necessarily beliefs and values. Consequences of globalisation such as individualisation, transience in relationships, immediacy in communication, the blurring of boundaries between work and leisure, between public and private and the reliance on information and communication technologies are part of their everyday lives. Some study participants feel dis-embedded from their traditional social relationships and seek to establish new ones, whereas others feel comfortable joking with anonymous others. Their intellectualised constructs of community and descriptions of the lived reality of community find reflections in a range of theoretical constructs in the literature, both reinforcing and shifting scholarly understandings of the concept of community.

    1993-01-01

    Thought experiments are performed in the laboratory of the mind. Beyond this metaphor it is difficult to say just what these remarkable devices for investigating nature are or how they work. Though most scientists and philosophers would admit their great importance, there has been very little serious study of them. This volume is the first book-length investigation of thought experiments. Starting with Galileo's argument on falling bodies, Brown describes numerous examples of the most influential thought experiments from the history of science. Following this introduction to the subject, some substantial and provocative claims are made, the principle being that some thought experiments should be understood in the same way that platonists understand mathematical activity: as an intellectual grasp of an independently existing abstract realm. With its clarity of style and structure, The Laboratory of the Mind will find readers among all philosophers of science as well as scientists who have puzzled over how thou...

    Investigation of Empiricism. On Ernst Mach's Conception of the Thought Experiment. The paper argues that Ernst Mach's conception of the thought experiment from 1897/1905 holds a singular position in the lively discussions and repeated theorizations that have continued up to the present in relation to this procedure. Mach derives the thought experiment from scientific practice, and does not oppose it to the physical experiment, but, on the contrary, endows it with a robust relation to the facts. For Mach, the thought experiment is a reliable means of determining empiricism, and at the same time a real, because open and unbiased, experimenting. To shed light on this approach, the paper carries out a close reading of the relevant texts in Mach's body of writings (in their different stages of revision) and proceeds in three steps: first, Mach's processual understanding of science will be presented, which also characterizes his research and publication practice (I. 'Aperçu' and 'Sketch'. Science as Process and Projection); then in a second step the physiological and biological justification and valorization of memory and association will be examined with which Mach limits the relevance of categories such as consciousness and will (II. The Biology of Consciousness. Or The Polyp Colony); against this background, thirdly, the specific empiricism can be revealed that Mach inscribes into the thought experiment by on the one hand founding it in the memory and association, and on the other by tracing it back to geometry, which he deploys as an experimenting oriented to experience (III. Thinking and Experience. The Thought Experiment). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The Pacific Research Platform is an initiative to interconnect Science DMZs between campuses across the West Coast of the United States over a 100 gbps network. The LHC @ UC is a proof of concept pilot project that focuses on interconnecting 6 University of California campuses. It is spearheaded by computing specialists from the UCSD Tier 2 Center in collaboration with the San Diego Supercomputer Center. A machine has been shipped to each campus extending the concept of the Data Transfer Node to a cluster in a box that is fully integrated into the local compute, storage, and networking infrastructure. The node contains a full HTCondor batch system, and also an XRootD proxy cache. User jobs routed to the DTN can run on 40 additional slots provided by the machine, and can also flock to a common GlideinWMS pilot pool, which sends jobs out to any of the participating UCs, as well as to Comet, the new supercomputer at SDSC. In addition, a common XRootD federation has been created to interconnect the UCs and give the ability to arbitrarily export data from the home university, to make it available wherever the jobs run. The UC level federation also statically redirects to either the ATLAS FAX or CMS AAA federation respectively to make globally published datasets available, depending on end user VO membership credentials. XRootD read operations from the federation transfer through the nearest DTN proxy cache located at the site where the jobs run. This reduces wide area network overhead for subsequent accesses, and improves overall read performance. Details on the technical implementation, challenges faced and overcome in setting up the infrastructure, and an analysis of usage patterns and system scalability will be presented.

Clogging appears to create a finger-like tracer transport, which could...... and closer to the substrate source during the experiments suggesting that the zone of clogging moved upstream. Three clogging models, K(β), from the literature were tested for their ability to describe the temporal changes in clogging at the scale of the sand box; the model of Clement et al.

The plug formation and biofilm-plug formation models both match the observed changes between the hydraulic conductivity of the sand box...

  9. Nine optical black-box experiments for lower-secondary students

    Rode, Henning; Friege, Gunnar

    2017-05-01

    In this paper a sequence of nine, easy to manufacture optical black-box experiments with increasing levels of difficulty, and supportive frameworks for physics classes are introduced. They have been evaluated in a lower-secondary school at the end of optics lessons. A black-box is a kind of experimental task where the inner structure is not visible to the experimenter. Using mirrors, beam-splitters, and blockers in a black-box to manipulate the light beam’s direction through this specific experiment, students are instructed to vary input and observe the output of light to get an idea of the possible inner structure. The presented sequence of black-box experiments requires a basic knowledge of the linear propagation of light and is suitable for beginner physics. Furthermore a framework for concrete implementation to physics classes is given, which covers suitable structure of class, examples for helpful worksheets, and authentic students’ solutions. The difficulty of the specific black-box experiments is given by the students’ success within observing input-output correlation and conclusion of an inner structure. The experiments’ implementation to physics classes may cover elaboration, practice, and aspects of the nature of science even in a beginner’s class. Evaluation has been conducted with students of young age (11-12 years old), however they are suitable for older students also. Although dealing with a time extensive sequence of experiments, students showed a high level of motivation throughout. Overall, implementing this sequence of black-box experiments is seen as valuable and helpful for physics classes.

A continuous time physical model of the heat dynamics of a building is considered and the results show that performing an optimal experiment corresponding to a MAP...

    In 1964 John Bell proved a theorem allowing the experimental test of whether what Einstein derided as "spooky actions at a distance" actually exist. We will see that they "do". Bell's theorem can be displayed with a simple, nonmathematical thought experiment suitable for a physics course at "any" level. And a simple, semi-classical derivation of…

  16. God put a thought into my mind: the charismatic Christian experience of receiving communications from God.

    Dein, Simon; Cook, Christopher C H

    2015-02-07

    The agentive aspects of communicative religious experiences remain somewhat neglected in the social sciences literature. There is a need for phenomenological descriptions of these experiences and the ways in which they differ from culturally defined psychopathological states. In this semi-structured interview study, eight congregants attending an evangelical church in London were asked to describe their experiences of God communicating with them. Communications from God were related to current events rather than to the prediction of future events. These communications were received as thoughts and do not generally reveal metaphysical insights, but rather they relate to the mundane world. They provided direction, consolation and empowerment in the lives of those receiving them. Individuals recounted that on occasion God sometimes speaks audibly, or accompanied by supernatural phenomena, but in the vast majority of cases, the way God speaks is through thoughts or impressions. In all instances, agency is maintained, individuals can choose to obey the thoughts/voices or not. The findings are discussed in relation to externalisation of agency and the phenomenon of thought insertion in schizophrenia.

  17. A History of Experiences and Thinking Men. The History of Political Thought according to Michael Oakeshott

    Directory of Open Access Journals (Sweden)

    Spartaco Pupo

    2014-12-01

    Full Text Available Michael Oakeshott conceives the history of European political thought as a structuring of ideas and arguments of the practical experience aimed to understanding political expressions in vogue in the culture of a people. It is not a continuous and cumulative history of abstract and disembodied ideas, as it is wrongly conceived, but of some men who thought politics in a certain way on the basis of the language and of the set of actions, moral beliefs and contingencies of the people which they belong to. The article highlights the comparison between Oakeshott, Quentin Skinner and Gianfranco Miglio on the search for the most appropriate method to be applied in the study of the history of political thought.

    Full Text Available The Snowden Archive-in-a-Box is an offline wireless network and web server providing private access to a replica of the Snowden Digital Surveillance Archive. The online version is hosted by Canadian Journalists for Free Expression. A work-in-development since April 2015, the Archive-in-a-Box is both a research tool and a tool for public education on data surveillance. The original version is powered with battery packs and housed in a 1960s spy style briefcase. When it is turned on, anybody in the vicinity can access the archive by connecting their wireless device to the Snowden Archive WiFi network and browsing to a website. Open the briefcase up and one finds a wood panel with a flatscreen inset, playing back the IP traffic of the archive's current users. Thus, while an audience such as a class of students or workshop group can access the Snowden documents and learn about mass surveillance from primary materials, they are also shown what data surveillance ‘looks like’. This Commentary explores my experiences during the first year of the Snowden Archive-in-a-Box. I examine my experiences as an international traveller carrying a suspicious briefcase of Top Secret materials and this project's reception by certain audiences. The project is still a prototype, yet it is quickly gathering a following and a number of permanent installations around the world. What could this mean for the future of surveillance education and leaks-enabled research?

    Thought Experiments in Historiographic Function: Max Weber on Eduard Meyer and the Question of Counterfactuality. Max Weber's remarks on his colleague Eduard Meyer regarding counterfactual reasoning in history reflects a significant shift during the Methodenstreit around 1900. The question of attributing historical change strictly to either individual causes or abstract general laws has been tackled in a new way: By counterfactual reasoning a historian should be able to detect the most significant (and therefore meaningful) cause, event, or action for a certain historical outcome. Following Fritz Ringer, this paper argues that given the predominating methods of the natural sciences, scholars of the humanities conducted historical research by counterfactual thought experiments. This way, Weber pried open contemporary narratives (e.g. historicism), and by employing a unique historical causal analysis he made way for refined concepts to offer a model of interpretation that gave hope for a more feasible, practice-oriented approach to historical research than the epistemological discussions had hitherto offered. © 2015 WILEY-VCH Verlag GmbH & Co.

  4. Language, games and the role of interpreters in psychiatric diagnosis: a Wittgensteinian thought experiment.

    2009-06-01

    British society is becoming increasingly culturally and linguistically diverse. This poses a major challenge to mental health services charged with the responsibility to work in ways that respect cultural and linguistic difference. In this paper we investigate the problems of interpretation in the diagnosis of depression using a thought experiment to demonstrate important features of language-games, an idea introduced by Ludwig Wittgenstein in his late work, Philosophical investigations. The thought experiment draws attention to the importance of culture and contexts in understanding the meaning of particular utterances. This has implications not only for how we understand the role of interpreters in clinical settings, and who might best be suited to function in such a role, but more generally it draws attention to the importance of involving members of black minority ethnic (BME) communities in working alongside mainstream mental health services. We conclude that the involvement of BME community development workers inside, alongside and outside statutory services can potentially improve the quality of care for people from BME communities who use these services.

    2013-03-01

    This article examines the main strands of thinking about gravity through the ages and the continuity of thought-experiments, from the early Greeks, through medieval times, to Galileo, Newton and Einstein. The key ideas are used to contextualise an empirical study of 247 children's ideas about falling objects carried out in China and New Zealand, including the use of scenarios involving thrown and dropped items, and objects falling down deep well holes (as in Carroll's Alice in Wonderland). The sample included 68 pre-school pupils, 68 primary school pupils, 56 middle school students, and 55 high school students; with approximately equal numbers in each group and of boys and girls in each group in each culture. The methodology utilised Piagetian interviews with three media (verbal language, drawing, and play-dough), a shadow stick; and everyday items including model people and soft model animals. The data from each group was categorised and analysed with Kolmogorov- Smirnov Two- Sample Tests and Spearman r s coefficients. It was hypothesised and confirmed (at K- S alpha levels .05; r s : p < .001) that cross-age and cross-cultural research and analysis would reveal that (a) an intuitive sense of gravity is present from an early age and develops in association with concepts like Earth shape and motion; (b) the development of concepts of gravity is similar in cultures such as China and New Zealand where teachers hold a scientific world view; and (c) children's concepts of Earth motion, Earth shape, and gravity are coherent rather than fragmented. It was also demonstrated that multi-media interviews together with concrete experiences and thought-experiments afforded children the opportunity to share their emerging concepts of gravity. The findings provide information that teachers might use for lessons at an appropriate level.

    In the use of ANOVA for hypothesis testing in animal science experiments, the assumption of homogeneity of errors often is violated because of scale effects and the nature of the measurements. We demonstrate a method for transforming data so that the assumptions of ANOVA are met (or violated to a lesser degree) and apply it in analysis of data from a physiology experiment. Our study examined whether melatonin implantation would affect progesterone secretion in cycling pony mares. Overall treatment variances were greater in the melatonin-treated group, and several common transformation procedures failed. Application of the Box-Cox transformation algorithm reduced the heterogeneity of error and permitted the assumption of equal variance to be met.

    2014-01-01

    The objective of this study was to explore women's expectations and experiences of undergoing second trimester abortion. This is a cross-sectional study using a screening questionnaire and semi-structured interviews for data collection. Thirty-one women filled out the questionnaire and 23 of them were later interviewed. The questionnaires were analyzed by descriptive statistics. The interviews were recorded, transcribed verbatim and analyzed with qualitative content analysis. Indications for the abortion were fetal malformation or unintended pregnancy. The women expressed similar feelings and these were irrespective for the reason for having an abortion. Both physical and mental pain was experienced during the abortion process and described by the women. Taking the mifepristone-pill was experienced as especially emotionally difficult for many participants. Professional support from the staff together with support from the partner, a friend or relative helped in transforming the worries related to something unknown to feelings of coping with a new and hard experience. Prior to the abortion most women stated that they did not want to view the fetus but women who chose to view the fetus described this as a way of confronting the reality and an opportunity to say farewell to the pregnancy/fetus. The analysis of the interview transcripts revealed five themes mirroring the women's experiences, thoughts and feelings related to the abortion. The decision to undergo second trimester abortion sometimes exposes women to strong and conflicting emotions which are irrespective for the reason for having an abortion. Despite this women do not regret their decision to terminate the pregnancy. This analysis shows that their rational thinking outweighs their emotionally difficult feelings. It is important for the attending staff to be responsive to the needs of each individual woman whatever the indication is for the abortion.

    With specimens representing over 2,000 individual meteorites, the Center for Meteorite Studies (CMS) at Arizona State University (ASU) is home to the world's largest university-based meteorite collection. As part of our mission to provide educational opportunities that expand awareness and understanding of the science of meteoritics, CMS continues to develop new ways to engage the public in meteorite and space science, including the opening of a new Meteorite Gallery, and expansion of online resources through upgrades to the CMS website, meteorites.asu.edu. In 2008, CMS was the recipient of a philanthropic grant to improve online education tools and develop loanable modules for educators. These modules focus on the origin of meteorites, and contain actual meteorite specimens, media resources, a user guide, and lesson plans, as well as a series of engaging activities that utilize hands-on materials geared to help students develop logical thinking, analytical skills, and proficiency in STEM disciplines. In 2010, in partnership with the ASU NASA Astrobiology Institute team, CMS obtained a NASA EPOESS grant to develop Virtual Field Trips (VFTs) complemented by loanable “Experience Boxes” containing lesson plans, media, and hands-on objects related to the VFT sites. One VFT-Box pair focuses on the record of the oldest multicellular organisms on Earth. The second VFT-Box pair focuses on the Upheaval Dome (UD) structure, a meteorite impact crater in Utah’s Canyonlands National Park. UD is widely accepted as the deeply eroded remnant of a ~5 kilometer impact crater (e.g. Kriens et al., 1999). The alternate hypothesis that the Dome was formed by the upwelling of salt from a deposit underlying the region (e.g. Jackson et al., 1998) makes UD an ideal site to learn not only about specific scientific principles present in the Next Generation Science Standards, but also the process of scientific inquiry. The VFTs are located on an interactive website dedicated to VFTs, vft

  13. The discount rate in the economic evaluation of prevention: a thought experiment.

    Bonneux, L; Birnie, E

    2001-02-01

    In the standard economic model of evaluation, constant discount rates devalue the long term health benefits of prevention strongly. This study shows that it is unlikely that this reflects societal preference. A thought experiment in a cause elimination life table calculates savings of eliminating cardiovascular disease from the Dutch population. A cost effectiveness analysis calculates the acceptable costs of such an intervention at a threshold of 18 000 Euro per saved life year. Cause specific mortality (all cardiovascular causes of death and all other causes) and health care costs (all costs of cardiovascular disease and all other causes of costs) by age and male sex of 1994. At a 0% discount rate, an intervention eliminating cardiovascular disease may cost 71 100 Euro. At the same threshold but at discount rates of 3% or 6%, the same intervention may cost 8100 Euro (8.8 times less) or 1100 Euro (65 times less). The standard economic model needs more realistic duration dependent models of time preference, which reflect societal preference.

    Full Text Available Abstract Background This project engages patients and physicians in the development of Decision Boxes, short clinical topic summaries covering medical questions that have no single best answer. Decision Boxes aim to prepare the clinician to communicate the risks and benefits of the available options to the patient so they can make an informed decision together. Methods Seven researchers (including four practicing family physicians selected 10 clinical topics relevant to primary care practice through a Delphi survey. We then developed two one-page prototypes on two of these topics: prostate cancer screening with the prostate-specific antigen test, and prenatal screening for trisomy 21 with the serum integrated test. We presented the prototypes to purposeful samples of family physicians distributed in two focus groups, and patients distributed in four focus groups. We used the User Experience Honeycomb to explore barriers and facilitators to the communication design used in Decision Boxes. All discussions were transcribed, and three researchers proceeded to thematic content analysis of the transcriptions. The coding scheme was first developed from the Honeycomb’s seven themes (valuable, usable, credible, useful, desirable, accessible, and findable, and included new themes suggested by the data. Prototypes were modified in light of our findings. Results Three rounds were necessary for a majority of researchers to select 10 clinical topics. Fifteen physicians and 33 patients participated in the focus groups. Following analyses, three sections were added to the Decision Boxes: introduction, patient counseling, and references. The information was spread to two pages to try to make the Decision Boxes less busy and improve users’ first impression. To try to improve credibility, we gave more visibility to the research institutions involved in development. A statement on the boxes’ purpose and a flow chart representing the shared decision

    Formaldehyde (CH2O) measurements from two independent instruments are compared with photochemical box model calculations. The measurements were made on the National Oceanic and Atmospheric Administration P-3 aircraft as part of the 1997 North Atlantic Regional Experiment (NARE 97). The data set considered here consists of air masses sampled between 0 and 8 km over the North Atlantic Ocean which do not show recent influence from emissions or transport. These air masses therefore should be in photochemical steady state with respect to CH2O when constrained by the other P-3 measurements, and methane oxidation was expected to be the predominant source of CH2O in these air masses. For this data set both instruments measured identical CH2O concentrations to within 40 parts per trillion by volume (pptv) on average over the 0–800 pptv range, although differences larger than the combined 2s total uncertainty estimates were observed between the two instruments in 11% of the data. Both instruments produced higher CH2O concentrations than the model in more than 90% of this data set, with a median measured-modeled [CH2O] difference of 0.13 or 0.18 ppbv (depending on the instrument), or about a factor of 2. Such large differences cannot be accounted for by varying model input parameters within their respective uncertainty ranges. After examining the possible reasons for the model-measurement discrepancy, we conclude that there are probably one or more additional unknown sources of CH2O in the North Atlantic troposphere.

    2012-06-03

    ADN students are a large yet distinct subgroup of nursing students who require research and understanding. The purpose of this study was to describe the thoughts, feelings, and experiences of American associate degree nursing (ADN) students who participated in a short study abroad course in a low-income country. A qualitative, narrative method was used. Three categories emerged from the analysis. Participants revealed thoughts of "constant comparisons", feelings of an "emotional journey", and they experienced "learning". Participants did not demonstrate perspective transformation as defined by Mezirow as participants signified no intent for social action. Several potential blocks to perspective transformation were identified: egocentrism/emotional disconnect, perceived powerlessness/being overwhelmed, and a vacation mindset. The findings provide insight into the student experience of studying abroad. Transformative learning is not a guaranteed result. Nurse educators must consider strategies to foster transformation including discussing global systemic oppressors, international relations, coping, connecting, and social action.

  20. A paedophile scan to prevent child sexual abuse in child care? A thought experiment to problematize the notion of alignment in Responsible Research and Innovation.

    de Jong, Irja Marije; Kupper, Frank; de Ruiter, Corine; Broerse, Jacqueline

    2017-12-01

    Responsible Research and Innovation (RRI) is a science policy concept that gained traction from 2000 onwards in the EU and US, in which alignment on purposes and values between different stakeholders is a key aspect. This thought experiment problematizes this particular notion: ethically acceptable and societally desirable outcomes are not necessarily achieved when alignment is a consequence of early closure. To argue this point, we took the example of the potential development of scanning technology for the detection of paedophilia among job applicants, for which indicators of broad societal support were found in an RRI project on neuroimaging. We analysed this case by looking through several lenses, obtained by structured and non-structured literature searches. We explored how facts and values are masked when a taboo topic is considered. This results in the black boxing of the problem definition, potential solutions and development trajectories. Complex unstructured problems can thus be perceived as manageable structured problems, which can in turn lead to irresponsible policies surrounding technology development. Responsible processes of research and technology development thus require the involvement of a critical reflector who is alert to signs of early closure and who prevents foreclosure of ongoing reflexive deliberation. There is an important role for ethical, legal and societal aspect studies within the framework of RRI. This paper shows that the concepts of "value/fact diversity masking" and "early discursive closure" are new avenues for RRI research.

    This effort, sponsored by the Defense Nuclear Agency under the Radiation Environments Program, was carried out to obtain measured data for benchmarking MASH, the Monte Carlo Adjoint Code System. MASH was developed to replace the Vehicle Code System, VCS, that has been used by the Department of Defense and NATO for calculating neutron and gamma-ray radiation fields and shielding protection factors inside armored vehicles and structures from nuclear weapon radiation. Free-field data were obtained at distances of 170- and 400-meters from the APR while in-box measurements were made at 400 meters only. The box, included to obtain neutron and gamma-ray reduction factors, was a 2-meter cube configuration having 0.1016-m-thick steel walls. Calculated data were obtained using MASH by analysts from the Oak Ridge National Laboratory and Science Applications International Corporation. Calculated (C) results were compared with experimental (E) data in terms of C/E ratios. Free-field and in-box neutron kerma generally agreed within ±20%, although some C/E comparisons fell outside this range depending upon the detector against which the calculated data were compared. For those cases where the C/E ratio is marginal or unacceptable, problems in the detector systems were acknowledged to be principal cause of the discrepancy. Generally poor agreement (∼25-35%) was achieved among the C/E ratios for the free-field gamma-ray kerma at the 170- and 400-m locations while excellent (10%, or better) C/E values were obtained for the in-box conditions. The discrepancy for the free-field comparison was attributed to the failure by the analysts to include a tree line adjacent to the measurement site in the calculational geometry. C/E values for the neutron and gamma-ray reduction factors ranged from 1% to 23% depending on the detector. 4 refs., 2 figs., 14 tabs

  2. Flavours of Thought: Towards A Phenomenology of Food-Related Experiences

    Full Text Available Phenomenology, as the study of structures of subjective experiences and consciousness, finds itself in the persistent struggle to claim its rightful place in contemporary research. Accordingly, this article will point out the relevance of first person reports for interdisciplinary investigations of the brain and mind. This is done by exploring the multidisciplinary field of food studies as a novel platform for discussion. The phenomenological inquiry is thus proposed as the vehicle and method to access food-related experience. By highlighting the important surplus, essential to grasping the process of pristine inner experience we adjoin a new perspective to the common focus on the content of experience. Consequently, this will extend the current insights pertinent to food-related research and moreover, give vital implications to our overall construction of concepts in science.

    The surface of some materials reacts very quickly on contact with air, either because it is oxidized or because it gets humidity from the air. For the sake of original surface observation by scanning electron microscopy (SEM), we conceived an airtight transfer box to keep the samples under vacuum from the place of manufacturing to the SEM chamber. This object is designed to fit in all the models of SEM including those provided with an airlock chamber. The design is voluntarily simplified to allow the manufacturing of the object by a standard mechanical workshop. The transfer box can be easily opened by gravity inside the SEM and allows the preservation of the best vacuum inside, before opening. SEM images and energy dispersive spectroscopy (EDX) analyses of metallic lithium and sodium samples are presented prior and after exposure to the air. X-ray Photoelectron Spectroscopy (XPS) analyses of all samples are also discussed in order to investigate the chemical environments of the detected elements. Copyright © 2018 Elsevier Ltd.

  5. The International year of soils: thoughts on future directions for experiments in soil erosion research

    2015-04-01

    The 2015 UN Year of Soils (IYS), implemented by the FAO, aims to increase awareness and understanding of the importance of soil for food security and essential ecosystem functions. The IYS has six specific objectives, ranging from raising the awareness among civil society and decision makers about the profound importance of soils, to the development of policies supporting the sustainable use of the non-renewable soil resource. For scientists and academic teachers using experiments to study soil erosion processes, two objectives appear of particular relevance. First is need for the rapid capacity enhancement for soil information collection and monitoring at all levels (global, regional and national). While at first glance, this objective appears to relate mostly to traditional mapping, sampling and monitoring, the threat of large-scale soil loss, at least with regards to their ecosystem services, illustrates the need for approaches of studying soils that avoids such irreversible destruction. Relying on often limited data and their extrapolation does not cover this need for soil information because rapid change of the drivers of change itself carry the risk of unprecedented soil reactions not covered by existing data sets. Experiments, on the other hand, offer the possibility to simulate and analyze future soil change in great detail. Furthermore, carefully designed experiments may also limit the actual effort involved in collecting the specific required information, e.g. by applying tests designed to study soil system behavior under controlled conditions, compared to field monitoring. For rainfall simulation, experiments should therefore involve the detailed study of erosion processes and include detailed recording and reporting of soil and rainfall properties. The development of a set of standardised rainfall simulations would widen the use data collected by such experiments. A second major area for rainfall simulation lies in the the education of the public about

    Full Text Available Nineteen university students experimented taking on the persona of an apprehended suicide bomber.  The role play explored the psychological mechanisms of dissociative phenomena, euphoria or a sense of empowerment contemplating suicide bombing; responses of imagined secondary traumatization; identification with the victim group; creation of fictive kin; choosing the (imagined target; and their (imagined moral reasoning.  Results were eerily similar to accounts of real (failed suicide bombers. Subjects identified with secondary trauma and fictive kin; and reported revenge and justice seeking as motivators; dissociation, some having experiences of euphoria or empowerment when contemplating strapping on a bomb. Their moral reasoning was nearly identical with the one of suicide bombers, despite none of them being Muslim. Most imagined targeting children or civilians. This leads us to the tentative conclusion that psychological mechanisms underlying the contemplation to engage in suicide terrorism may be universal.

  8. Creep buckling: an experiment, an 'exact' solution and some simple thoughts

    1986-01-01

    The paper presents attempts to analyse and understand a carefully conducted creep buckling experiment. The analysis was conducted using the ABAQUS Finite Element Code coupled to a number of plausible creep laws. The results show good agreement between ABAQUS runs and experimental deflections but it is difficult to reproduce the early loads. A simple model of buckling analysis for n-power creep laws is derived as an aid to understanding the development of the deflections for non-linear creep laws. In particular, the model suggests why deflections develop so rapidly and how the creep deflection development relates to the elastic behaviour. (author)

    It has been proposed that insecure attachment can have adverse effects on the course of psychosis once symptoms have emerged. There is longitudinal evidence that increased insecure attachment is associated with increased severity of psychotic symptoms. The present study examined whether in the flow of daily life attachment insecurity fluctuates, whether elevated stress precedes the occurrence of attachment insecurity, and whether elevated attachment insecurity precedes the occurrence of paranoia. Twenty clinical participants with a psychosis-spectrum diagnosis and twenty controls were studied over six consecutive days using the experience sampling method (ESM). The findings revealed that fluctuations in attachment insecurity were significantly higher in the clinical group, that elevated stress predicted a subsequent increase in attachment insecurity, and that elevated attachment insecurity predicted a subsequent increase in paranoia; this effect was not observed in auditory hallucinations once co-occurring symptoms were controlled for. Finally, although previous ESM studies have shown that low self-esteem precedes the occurrence of paranoia, attachment insecurity continued to predict paranoia even when self-esteem was controlled for. The findings suggest that attachment security may be associated with a lower risk of paranoia, and that psychological interventions should address attachment beliefs and work towards establishing a sense of attachment security.

    2010-07-01

    22q11 deletion syndrome (22q11DS) is one of the most common multiple anomaly syndromes, and many dentists are likely to meet patients with the syndrome. Odontological research has focused on describing and analysing conditions/concepts based on the current state of knowledge within the dental profession. Yet, these research topics are not necessarily the most important issues for the patients. To explore and describe, by use of Grounded theory, parents' experiences of oral health issues and needs for dental care in their children with 22q11DS. Twelve parents from different regions in Sweden were interviewed. Analyses were carried out according to Grounded theory. Parents recognised good oral health as important for the wellbeing of their children. Oral health was a concern and the parents described the fight for this as struggling in vain for good oral health in their child. Parents not only described their children's oral health as important but also hard to gain. Thus, it is important that all patients with disabilities, regardless of whether there is a defined medical diagnosis or not, are identified and well taken care of in the dental care system.

  11. Emotional Reactions to the Outcomes of Decisions: The Role of Counterfactual Thought in the Experience of Regret and Disappointment.

    Regret and disappointment are emotions that can be experienced in response to an unfavorable outcome of a decision. Previous research suggests that both emotions are related to the process of counterfactual thinking. The present research extends this idea by combining it with ideas from regret and disappointment theory. The results show that regret is related to behavior-focused counterfactual thought in which the decision-maker's own actions are changed, whereas disappointment is related to situation-focused counterfactual thought in which aspects of the situation are changed. In Study 1 participants (N = 130) were asked to recall an autobiographical episode of either a regretful or a disappointing event. When asked to undo this event, regret participants predominantly changed their own actions, whereas disappointment participants predominantly changed aspects of the situation. In Study 2 all participants (N = 50) read a scenario in which a person experiences a negative event. Participants who were instructed to undo the event by changing the person's actions reported more regret than disappointment, while participants who were instructed to undo the event by changing aspects of the situation reported more disappointment than regret. Study 3 (N = 140) replicated the findings from Study 2 with a different scenario, and a design in which regret and disappointment were measured between rather than within subjects. In the discussion we address the relation among counterfactual thinking, attributions and affective reactions to decision outcomes, and the implications for decision research.

    Policy formulation and adoption often happen in a black box. Implementation challenges affect and modify the nature of a policy. We analyzed hospitals' autonomy policy in Iran that was intended to reduce hospitals' financial burden on government and improve their efficiency. We followed a retrospective case-study methodology, involving inductive and deductive analyses of parliamentary proceedings, policy documents, gray literature, published papers and interview transcripts. We analyzed data to develop a policy map that included important dates and events leading to the policy process milestones. We identified four time-periods with distinctive features: 'moving toward the policy' (1989 - 1994), disorganized implementation' (1995 - 1997), 'continuing challenges and indecisiveness in hospitals financing' (1998 - 2003), and 'other structural and financial policies in public hospitals' (2004 to date). We found that stakeholders required different and conflicting objectives, which certainly resulted in an unsatisfactory implementation process. The policy led to long-lasting and often negative changes in the hospital sector and the entire Iranian health system. Hospital autonomy appeared to be an ill-advised policy to remedy the inefficiency problems in low socioeconomic areas of the country. The assumption that hospital autonomy reforms would necessarily result in a better health system, may be a false assumption as their success relies on many contextual, structural and policy implementation factors.

  14. Further Insight Relative to Cavity Radiation: A Thought Experiment Refuting Kirchhoff's Law (Letters to Progress in Physics

    Directory of Open Access Journals (Sweden)

    Robitaille P.-M.

    2014-01-01

    Full Text Available Kirchhoff’s law of thermal emission demands that all cavities contain blackbody, or normal, radiation which is dependent solely on the temperature and the frequency of observation, while remaining independent of the nature of t he enclosure. For over 150 years, this law has stood as a great pillar for those who believe that gaseous stars could emit a blackbody spectrum. However, it is well-known that, u nder laboratory condi- tions, gases emit in bands and cannot produce a thermal spectrum. Furthermore, all laboratory blackbodies are constructed from nearly ideal a bsorbers. This fact strongly opposes the validity of Kirchhoff’s formulation. Clearly, if Kirchhoff had been correct, then laboratory blackbodies could be constructed of any arbitrary material. Through the use of two cavities in temperature equilibrium with one another, a thought experiment is presented herein which soundly refutes Kirchhoff’s law of thermal emission.

  15. Brain functional connectivity during the experience of thought blocks in schizophrenic patients with persistent auditory verbal hallucinations: an EEG study.

    Thought blocks (TBs) are characterized by regular interruptions in the stream of thought. Outward signs are abrupt and repeated interruptions in the flow of conversation or actions while subjective experience is that of a total and uncontrollable emptying of the mind. In the very limited bibliography regarding TB, the phenomenon is thought to be conceptualized as a disturbance of consciousness that can be attributed to stoppages of continuous information processing due to an increase in the volume of information to be processed. In an attempt to investigate potential expression of the phenomenon on the functional properties of electroencephalographic (EEG) activity, an EEG study was contacted in schizophrenic patients with persisting auditory verbal hallucinations (AVHs) who additionally exhibited TBs. In this case, we hypothesized that the persistent and dense AVHs could serve the role of an increased information flow that the brain is unable to process, a condition that is perceived by the person as TB. Phase synchronization analyses performed on EEG segments during the experience of TBs showed that synchrony values exhibited a long-range common mode of coupling (grouped behavior) among the left temporal area and the remaining central and frontal brain areas. These common synchrony-fluctuation schemes were observed for 0.5 to 2s and were detected in a 4-s window following the estimated initiation of the phenomenon. The observation was frequency specific and detected in the broad alpha band region (6-12Hz). The introduction of synchrony entropy (SE) analysis applied on the cumulative synchrony distribution showed that TB states were characterized by an explicit preference of the system to be functioned at low values of synchrony, while the synchrony values are broadly distributed during the recovery state. Our results indicate that during TB states, the phase locking of several brain areas were converged uniformly in a narrow band of low synchrony values and in a

    Full Text Available During a school cycle of a year we implemented an experience of philosophy with children inspired by the thoughts of Michel Foucault. The objective of our meetings was to foster thought-experiments aimed at problematizing the world around us and thinking otherwise. In the course of our experience, the thoughts of children led to different questions and reflections which we have organized according to five categories in dialogue with the ideas of Foucault: 1 critical thinking, 2 self-criticism, 3 curiosity, 4 relationship with the truth and 5 thinking otherwise. In this paper, we share a part of the expressions that, from our perspective, show how children thought differently about the world that surrounds us, and their own thinking.

  17. "Virtual shear box" experiments of stress and slip cycling within a subduction interface mélange

    Webber, Sam; Ellis, Susan; Fagereng, Åke

    2018-04-01

    What role does the progressive geometric evolution of subduction-related mélange shear zones play in the development of strain transients? We use a "virtual shear box" experiment, based on outcrop-scale observations from an ancient exhumed subduction interface - the Chrystalls Beach Complex (CBC), New Zealand - to constrain numerical models of slip processes within a meters-thick shear zone. The CBC is dominated by large, competent clasts surrounded by interconnected weak matrix. Under constant slip velocity boundary conditions, models of the CBC produce stress cycling behavior, accompanied by mixed brittle-viscous deformation. This occurs as a consequence of the reorganization of competent clasts, and the progressive development and breakdown of stress bridges as clasts mutually obstruct one another. Under constant shear stress boundary conditions, the models show periods of relative inactivity punctuated by aseismic episodic slip at rapid rates (meters per year). Such a process may contribute to the development of strain transients such as slow slip.

Subjects who reported more mind wandering during the laboratory task endorsed more mind-wandering experiences during everyday life (and were more likely to report worries as off-task thought content). We also conceptually replicated laboratory findings that mind wandering predicts task performance: Subjects rated their daily-life performance to be impaired when they reported off-task thoughts, with greatest impairment when subjects' mind wandering lacked metaconsciousness. The propensity to mind wander appears to be a stable cognitive characteristic and seems to predict performance difficulties in daily life, just as it does in the laboratory.

    Kullie, Ossama

    2018-02-01

    The measurement of the tunneling time (T-time) in today's attosecond and strong field (low-frequency) experiments, despite its controversial discussion, offers a fruitful opportunity to understand time measurement and the time in quantum mechanics. In addition, as we will see in this work, a related controversial issue is the particulate nature of the radiation. The T-time in attosecond experiment and its different aspects and models, is discussed in this work, especially in relation to my model of real T-time (Kullie, 2015), where a good agreement with the experiment and an intriguing similarity to the Bohr-Einstein photon box Gedanken experiment was found. The tunneling process itself is still not well understood, but I am arguing that a scattering mechanism (by the laser wave packet) offers a possibility to understand the tunneling process in the tunneling region. This is related to the question about the corpuscular nature of light which is widely discussed in modern quantum optics experiments.

  6. Comparison of upconing under vertical and horizontal wells in freshwater lenses: sand-box experiments and numerical modeling

    2013-04-01

    Freshwater lenses on islands and in inland areas are often the primary freshwater resource there. The fragile equilibrium between saline and fresh groundwater can be disrupted by excessive pumping, leading to an upward migration of the saline water underneath the well. Sand-box experiments were conducted to compare the upconing at vertical and horizontal wells pumping from a freshwater lens. Results were then compared to numerical simulations. To simulate the cross-section of an "infinite strip island", an acrylic box with a spacing of 5 cm was filled with coarse sand. After saturating the model with degassed saltwater from bottom to top, freshwater recharge was applied from above. By coloring the infiltrating freshwater with different tracer colors using uranine and indigotine we were able to visualize flow paths during pumping. A horizontal and a vertical well were placed at the left and right side of the symmetric island. Both had equal diameter, screen length, depth of placement, and distance to shore. Three increasing pumping rates were applied to each well successively and the electrical conductivity of the abstracted water was continuously measured using a through-flow cell. Results show that no saltwater entered the wells when pumping at the lowest rate. Still, slight saltwater upconing and a shift of the freshwater divide in the island were observed. At the second rate a clear saltwater breakthrough into the vertical well occurred, while the electrical conductivity remained nearly unchanged in the horizontal well. Applying the third (highest) abstraction rate to each of the wells saltwater entered both wells, exceeding drinking water standards in the vertical well. The described behavior indicates the advantage of horizontal over vertical wells on islands and in coastal zones prone to saltwater up-coning. Numerical simulations show similar patterns, even though deviations exist between the second and the third pumping rate, which are under and

  7. Channel box

    1993-01-01

    In a channel box of a BWR type reactor, protruding pads are disposed in axial position on the lateral side of a channel box opposing to a control rod and facing the outer side portion of the control rod in a reactor core loaded state. In the initial loading stage of fuel assemblies, channel fasteners and spacer pads are abutted against each other in the upper portion between the channel boxes sandwiching the control rod therebetween. Further, in the lower portion, a gap as a channel for the movement of the control rod is ensured by the support of fuel support metals. If the channel box is bent toward the control rod along with reactor operation, the pads are abutted against each other to always ensure the gap through which the control rod can move easily. Further, when the pads are brought into contact with each other, the bending deformation of the channel box is corrected by urging to each other. Thus, the control rod can always be moved smoothly to attain reactor safety operation. (N.H.)

    2015-12-01

    This study investigated the effects of trait-level hostility, interface types, and character identification on aggressive thoughts and overall game experience after playing a violent video game. Results showed that the mapping interface made participants with high trait-level hostility more readily accessible to aggressive contracts, yet it did not have any significant impact for participants with low trait-level hostility. Participants with low trait-level hostility reported more positive game experience in the mapping interface condition, while participants with high trait-level hostility in the same condition reported more negative game experience. Results also indicated that character identification has moderating effects on activating aggressive thoughts and mediating effects on overall game experience. Implications regarding possible ways of reducing potentially negative outcomes from violent games are discussed.

  10. Glove box

    1990-01-01

    Wire rope earthquake proof supports having sufficient vibration transmitting and attenuating property are disposed between a fixed floor and the bottom of a glove box in order to improve earthquake proofness of the glove box. The vertical weight of the glove box is supported by support legs slidable on the surface of the fixed floor. The wire rope earthquake-proof supports when undergoing a load, cause stretching and rolling against the external force such as earthquakes, and provide flexible spring support and cause a great damping due to friction with strands. Further, the vertical weight is always supported by the support legs and, when a horizontal weight is applied, the glove box slides on the fixed floor freely with slidable members. In this way, stress concentration generated at joint portions of columns and beams can be moderated greatly and earthquake proofness can be improved. Further, quality control and maintenance for the device is almost unnecessary owing to excellent fatigue-resistant characteristics of the wire rope earthquake proof supports. (N.H.)

For more than four decades, one of the most captivating and celebrated science communicators of our time has challenged the public to think carefully about the foundations of nature and the inseparable entanglement of science and society. In Third Thoughts Steven Weinberg casts a wide net: from the cosmological to the personal, from astronomy, quantum mechanics, and the history of science to the limitations of current knowledge, the art of discovery, and the rewards of getting things wrong. Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls, or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public...

    Wlodek Rabinowicz

    2010-12-01

    Full Text Available In “Thought Experiments and Utilitarianism”, which is a comment on my “Utilitarianism by Way of Preference Change?”, Krzysztof Saja delineates three alternative ways in which one might interpret Richard Hare’s famous thought experiments involving role reversals. He suggests that each of them would underwrite Hare’s claim that moral deliberation transforms an interpersonal conflict of preferences into an intrapersonal one, which obtains between the deliberator’s own preferences. In this reply to Saja (“Role Reversals”, I discuss the three proposals in turn and argue that the first two do not solve the problem. The third one, which was already considered in my original paper, is based on Zeno Vendler’s suggestion that role reversals in moral thought-experiments are merely different ‘takes’ on one and the same real situation, as seen from different subjective perspectives. I argue that, in order to succeed in transforming interpersonal preference conflicts into intrapersonal ones, this proposal requires equating empathy with sympathy, which Hare would not be prepared to do.

    The outages caused by storms bringing down trees on power transmission lines on Boxing Day 1998 in Scotland, Northern Ireland and Northern England forced ScottishPower to modify its pylon policy. The results of the analysis of pylons requiring work by the Rural Care Team at ScottishPower are summarised, and the identification of the problems caused by the Sitk spruce is reported. The selection of the relocation and clearance remediation option, the policy of replacing one tree with two, the approach to landowners, and the need to consider environmental concerns during the planning of networks are discussed.

  16. Beauty Requires Thought.

    Science.gov (United States)

    Brielmann, Aenne A; Pelli, Denis G

    2017-05-22

    The experience of beauty is a pleasure, but common sense and philosophy suggest that feeling beauty differs from sensuous pleasures such as eating or sex. Immanuel Kant [1, 2] claimed that experiencing beauty requires thought but that sensuous pleasure can be enjoyed without thought and cannot be beautiful. These venerable hypotheses persist in models of aesthetic processing [3-7] but have never been tested. Here, participants continuously rated the pleasure felt from a nominally beautiful or non-beautiful stimulus and then judged whether they had experienced beauty. The stimuli, which engage various senses, included seeing images, tasting candy, and touching a teddy bear. The observer reported the feelings that the stimulus evoked. The time course of pleasure, across stimuli, is well-fit by a model with one free parameter: pleasure amplitude. Pleasure amplitude increases linearly with the feeling of beauty. To test Kant's claim of a need for thought, we reduce cognitive capacity by adding a "two-back" task to distract the observer's thoughts. The distraction greatly reduces the beauty and pleasure experienced from stimuli that otherwise produce strong pleasure and spares that of less-pleasant stimuli. We also find that strong pleasure is always beautiful, whether produced reliably by beautiful stimuli or just occasionally by sensuous stimuli. In sum, we confirm Kant's claim that only the pleasure associated with feeling beauty requires thought and disprove his claim that sensuous pleasures cannot be beautiful.

  17. Confused thoughts

    Tolonen, P.

    1999-01-01

    One of the special characters of public discussion on nuclear energy is the aggressivity. This writing tries to point out some arguments defending the use of nuclear energy also in the future. Although nuclear energy is very unfashionable at the moment, especially among youth, it still remains as a remarkable option to meet the increasing demand of energy. All the renewables and other production forms seem to leave a gap in the required energy supply. Some conventional forms of energy should be excluded because of the green house emission limitations. Fusion energy and other futuristic options do not seem to be near enough in the future. This means, that there still seems to be need for nuclear energy in the future. One of the topical problems in the nuclear field is the soon forthcoming collapse of experience and expertise due to the retirement of the current establishment. This urges to encourage the young generation to join and to stay in the nuclear field. As well it sets demand for public acceptance for nuclear energy among the youth. This seems to be a problem, but how to cope with it

    E-Squared is a lab manual with simple experiments to prove once and for all that there really is a good, loving, totally hip force in the universe. Rather than take it on faith, you are invited to conduct ten 48-hour experiments to prove each of the principles in this book. Yes, you read that right. It says prove. The experiments, each of which can be conducted with absolutely no money and very little time expenditure, demonstrate that spiritual principles are as dependable as gravity, as consistent as Newton's 2nd law of motion. For years, you've been hoping and praying that spiritual principles are true. Now, you can know.

    Full Text Available Em olericultura, o interesse é a produção de frutos comercializáveis. Em experimentos nessa área agronômica comumente são avaliadas variáveis tais como a fitomassa e o número de frutos. No entanto, essas variáveis apresentam uma característica particular que está relacionada com sua ausência no momento da colheita. Este atributo é representado por valores zero, gerando certa variabilidade e afetando a análise de variância dos dados. Assim, teve-se por objetivo definir uma transformação adequada para as variáveis observadas em colheitas por planta de experimentos com a cultura do pimentão, realizados em ambiente protegido, visando estabilizar a variabilidade gerada pela presença de valores zero nas múltiplas colheitas dos frutos. Os experimentos foram realizados nas estações sazonais verão/outono e inverno/primavera, utilizando a família de transformações de Box-Cox, com uma adaptação apresentada em Yamamura (1999. Apesar da redução na variabilidade e a normalidade dos resíduos, observadas em todos os experimentos, o uso do método não foi eficiente para tornar as variâncias homocedásticas. Concluiu-se que para dados de colheitas por planta de experimentos com pimentão, avaliando a fitomassa e o número de frutos, a transformação indicada é a inversa da raiz quarta.The major purpose of vegetable crops production systems is the profitable and economically viable yield of marketable products.

    Maier-Komor, P; Wieser, J; Ulrich, A

    1999-01-01

    An UHV box coater was set up for the deposition of highly reflective layers in the vacuum ultraviolet (VUV) wavelength range on large-area mirror substrates. The VUV mirrors are needed for the ring imaging Cherenkov (RICH) detector of the high-acceptance di-electron spectrometer (HADES). The complete dry vacuum system is described. The spatial deposition distribution from the evaporation sources was measured. The reflectivity of the Al mirror layer was optimized for the wavelength range of 145-210 nm by varying the thickness of the MgF sub 2 protective layer. The setup for measuring the reflectivity in the VUV range is described and reflectivity data are presented.

    By a "box integral" we mean here an expectation $\\langle|\\vec r - \\vec q|^s \\rangle$ where $\\vec r$runs over the unit $n$-cube,with $\\vec q$ and $s$ fixed, explicitly:\\begin eqnarray*&&\\int_01 \\cdots \\int_01 \\left((r_1 - q_1)2 + \\dots+(r_n-q_n)2\\right)^ s/2 \\ dr_1 \\cdots dr_n.\\end eqnarray* The study ofbox integrals leads one naturally into several disparate fields ofanalysis. While previous studies have focused upon symbolic evaluationand asymptotic analysis of special cases (notably $s = 1$), we workherein more generally--in interdisciplinary fashion--developing resultssuch as: (1) analytic continuation (in complex $s$), (2) relevantcombinatorial identities, (3) rapidly converging series, (4) statisticalinferences, (5) connections to mathematical physics, and (6)extreme-precision quadrature techniques appropriate for these integrals.These intuitions and results open up avenues of experimental mathematics,with a view to new conjectures and theorems on integrals of thistype.

  3. Psychological effects of thought acceleration.

    Pronin, Emily; Jacobs, Elana; Wegner, Daniel M

    2008-10-01

    Six experiments found that manipulations that increase thought speed also yield positive affect. These experiments varied in both the methods used for accelerating thought (i.e., instructions to brainstorm freely, exposure to multiple ideas, encouragement to plagiarize others' ideas, performance of easy cognitive tasks, narration of a silent video in fast-forward, and experimentally controlled reading speed) and the contents of the thoughts that were induced (from thoughts about money-making schemes to thoughts of five-letter words). The results suggested that effects of thought speed on mood are partially rooted in the subjective experience of thought speed. The results also suggested that these effects can be attributed to the joy-enhancing effects of fast thinking (rather than only to the joy-killing effects of slow thinking). This work is inspired by observations of a link between "racing thoughts" and euphoria in cases of clinical mania, and potential implications of that observed link are discussed.

    The stability of an emulsified liquid membrane composed of Span80 as a surfactant, D2EHPA as an extractant and sulfuric acid as an internal phase was first studied according to different diluents and many operating parameters using the Plackett-Burman design of experiments. Then the removal of methylene blue from an aqueous solution has been carried out using this emulsified liquid membrane at its stability conditions. The effects of operating parameters were analysed from the Box-Behnken design of experiments. The optimization of the extraction has been realized applying the response surface methodology and the results showed that the dye extraction yielding 98.72% was achieved at optimized conditions.

    Einstein often performed thought experiments with 'photon boxes', storing fields for unlimited times. This is yet but a dream. We can nevertheless store quantum microwave fields in superconducting cavities for billions of periods. Using circular Rydberg atoms, it is possible to probe in a very detailed way the quantum state of these trapped fields. Cavity quantum electrodynamics tools can be used for a direct determination of the Husimi Q and Wigner quasi-probability distributions. They provide a very direct insight into the classical or non-classical nature of the field

  6. Money priming can change people's thoughts, feelings, motivations, and behaviors: An update on 10 years of experiments.

    Vohs, Kathleen D

    2015-08-01

    Caruso, Vohs, Baxter, and Waytz (2013) posited that because money is used in free market exchanges, cues of money would lead people to justify and support the systems that allow those exchanges to take place. Hence, the authors predicted that money primes would boost system justification, social dominance, belief in a just world, and free market ideology, and found supportive evidence. Rohrer, Pashler, and Harris (2015) failed to replicate those effects. This article discusses the factors that predict priming effects, and particularly those pertinent to differences between Caruso et al. and Rohrer et al. Variations in a prime's meaning, the ease with which primed content comes to mind, the prime's motivational importance, and the ambiguity of the outcome situation influence the impact of the prime. Money priming experiments (totaling 165 to date, from 18 countries) point to at least 2 major effects. First, compared to neutral primes, people reminded of money are less interpersonally attuned. They are not prosocial, caring, or warm. They eschew interdependence. Second, people reminded of money shift into professional, business, and work mentality. They exert effort on challenging tasks, demonstrate good performance, and feel efficacious. Money priming is not the same as priming another popular means of exchange, credit cards, and can have bigger effects when there is an implied connection between the self and having money. The practical benefits of money have been studied by other disciplines for decades, and the time is now for psychologists to study the effects of merely being reminded of money.

    The international disaster victim identification (DVI) response to the Boxing Day tsunami, led by the Royal Thai Police in Phuket, Thailand, was one of the largest and most complex in DVI history. Referred to as the Thai Tsunami Victim Identification operation, the group comprised a multi-national, multi-agency, and multi-disciplinary team. The traditional DVI approach proved successful in identifying a large number of victims quickly. However, the team struggled to identify certain victims due to incomplete or poor quality ante-mortem and post-mortem data. In response to these challenges, a new 'near-threshold' DVI management strategy was implemented to target presumptive identifications and improve operational efficiency. The strategy was implemented by the DNA Team, therefore DNA kinship matches that just failed to reach the reporting threshold of 99.9% were prioritized, however the same approach could be taken by targeting, for example, cases with partial fingerprint matches. The presumptive DNA identifications were progressively filtered through the Investigation, Dental and Fingerprint Teams to add additional information necessary to either strengthen or conclusively exclude the identification. Over a five-month period 111 victims from ten countries were identified using this targeted approach. The new identifications comprised 87 adults, 24 children and included 97 Thai locals. New data from the Fingerprint Team established nearly 60% of the total near-threshold identifications and the combined DNA/Physical method was responsible for over 30%. Implementing the new strategy, targeting near-threshold cases, had positive management implications. The process initiated additional ante-mortem information collections, and established a much-needed, distinct "end-point" for unresolved cases. Copyright © 2015 Elsevier Ireland Ltd.

    2014-07-01

    Full Text Available This article explores the challenges posed by an archival interest in the broad palimpsest of daily life left on social networks that are controlled by private corporations. It addresses whether social networks should be archived for the benefit of future generations and proposes a policy thought experiment to help grapple with these questions, namely, the proposal for the formation of the public interest-oriented Networked Memory Project by the Library of Congress for the archiving of social networks. My discussion of the challenges posed by this thought experiment will focus on the U.S. legal framework within which the Library of Congress operates and take Facebook. To the extent that social networks have user-generated contents that range from the highly “private” to “public” as opposed to other networked platforms that contain materials that are considered “public”, the bar for the historical archival of social networks is much higher. Almost every archival effort must contend with the legal hurdle of copyright, but the archiving of social networks must also address how to handle the potentially sensitive nature of materials that are considered “private” from the perspective of the social and legal constructions of privacy. My theoretical exercise of proposing the formation of the Networked Memory Project by the Library of Congress responds to the need to consider the benefits of a public interest-oriented archive of social networks that can counter the drawbacks of the incidental corporate archiving taking place on social networks.

    We consider n>=2 identical rockets: R1 ,R2 , ..., Rn. Each of them moving at constant different velocities respectively v1 ,v2 , ..., vn on parallel directions in the same sense. In each rocket there is a light clock, the observer on earth also has a light clock. All n + 1 light clocks are identical and synchronized. The proper time Δt' in each rocket is the same. (1) If we consider the observer on earth and the first rocket R1, then the non-proper time Δt of the observer on earth is dilated with the factor D(v1) : or Δt = Δt' D(v1) (1) But if we consider the observer on earth and the second rocket R2 , then the non-proper time Δt of the observer on earth is dilated with a different factor D(v2) : or Δt = Δt' D(v2) And so on. Therefore simultaneously Δt is dilated with different factors D(v1) , D(v2), ..., D(vn) , which is a multiple contradiction.

    Highlights: → The definition of the momentum of light inside matter is studied. → Fully relativistic analysis of the dielectric 'Einstein box' thought experiment. → Minkowski, Abraham and the total energy-momentum tensors are derived in detail. → Some assumptions hidden in the usual Einstein box argument are identified. → The Abraham momentum is not uniquely selected as the momentum of light in this case. - Abstract: We analyse the 'Einstein box' thought experiment and the definition of the momentum of light inside matter. We stress the importance of the total energy-momentum tensor of the closed system (electromagnetic field plus material medium) and derive in detail the relativistic expressions for the Abraham and Minkowski momenta, together with the corresponding balance equations for an isotropic and homogeneous medium. We identify some assumptions hidden in the Einstein box argument, which make it weaker than it is usually recognized. In particular, we show that the Abraham momentum is not uniquely selected as the momentum of light in this case.

    An air-impervious electrical box to facilitate air sealing a house comprises an integral, rigid box body having a continuous flange, integral with the body, circumscribing and outwardly extending from the sides of the body. This flange is rearwardly positioned behind the front edges of the sides of the body a predetermined distance so that the electrical box may be secured to framing by nailing through the flange. Drywall is then secured to the frame on top of and adjecent to the flange. Such box eliminates the necessity for solid backing and minimizes passage of air through the box and space between the drywall and the box.

    To analyze and summarize Professor LIU Feng-bin's clinical experience and academic thoughts on gastroesophageal reflux disease (GERD), the study group adopted the retrospective study for case series and expert interview, extracted the retrospective data, including the herbs, diseases, syndrome type, medical expense and quantity of herbs of GERD patients attended the First Affiliated Hospital of Guangzhou University of Chinese Medicine. Statistical description and binary Logistic regression were used for the identification and modification of syndrome type and initial core herbs. After expert interviews were performed for the syndrome type and herbs, the final scheme were formed. A total of 112 GERD patients ages(48.97±13.13)y; male: 35 (31.3%), female: 77(68.7%) were enrolled. The numbers of patients with liver and stomach incoordination syndrome, heat stagnation of liver and stomach syndrome, syndrome of dual deficiency of Qi and Yin, syndrome of spleen deficiency and dampness-heat, spleen-stomach disharmony syndrome were 40, 26, 19, 17 and 10, respectively. The patients used totally 80 herbs, and 26 of them had significant differences among different syndrome groups. According to the logistic regression analysis on the 23 herbs used by 112 patients, the herbs scheme was modified for the second time. After the expert interviews and modification, the final consensus was reached. The main causes for GERD were dietary irregularities, moodiness, and weak constitution. The basic mechanism of GERD was spleen deficiency with Qi adverseness. The spleen-stomach disharmony syndrome was deleted by expert interviews. The 10 core herbs for GERD treatment were Taizishen(Pseudostellariae Radix), Fuling(Poria), Baizhu(Atractylodismacrocephalae Rhizoma), Gancao(Glycyrrhizae Radix Et Rhizoma), Zhebeimu(Fritillariae Thunbergii Bulbus), Haipiaoxiao(Sepiae Endoconcha), Zhiqiao(Aurantii Fructus), Chenxiang(Alosewood), Pugongying(Taraxaci Herba), Zhizitan(Cape Jasmine Fruit).

    2015-10-01

    Full Text Available The article examines the role which a discussion around the book of the American philosopher and psychologist W. James «The Varieties of Religious Experience» played in the development of the Russian philosophy and psychology of religion. The author carries out an analytical review of the Russian reception of James’s philosophy and psychology of religion inasmuch as they are connected with the concept of religious experience. The main attention is paid to the reception of the ideas of the American philosopher in the beginning of the 20th century and to its continuation among Russian emigrants. The author presents short summaries of debates concerning James’s ideas in the principal Russian philosophical and theological periodicals: «Questions of Philosophy and Psychology», «Logos», «The Russian Thought», «Theological Review», «Faith and Reason» — and then points out those authors who presented their understanding of the ideas of the American philosopher outside these periodicals. Despite the fact that the reception as a whole had philosophical character (it was mostly representatives of theological academies who were ready to develop the psychology of religion «in James’s spirit», one can say that in its framework the growth of the psychology of religion as a special field of research was outlined. And what is even more important — there emerged psychologism as a special form of cognitive interest in the field of religious studies. Not only philosophers and psychologists, but theologians as well learned to look on religion as a psychological phenomenon, «experience». And this concept step by step moved forward into the centre of the psychological study of religion as its own specifi c subject.

    . "Let me tell you about my little box": phenomenological study on the experience of living with a totally implantable central venous catheter. Many variables impact on the choice to implant a totally implantable long-term central venous catheter's (Port), in spite of its proven efficacy. The patients' perception is pivotal, and only few qualitative studies dig deep into patients' feelings and experiences. To understand if, and how, the Port affects the patient's life. Qualitative phenomenological study based on semi-structured interviews on a convenience sample of patients implanted a Port, selected in an oncohematology Day Hospital in Milan. The analysis was carried out by three researchers with a phenomenological method. Four main themes, and sub-themes, emerged from twenty interviews. Relief, both physical and psychological; the process of the choice of inserting the Port and the importance of thinking about its positioning since the beginning of the treatment course; the symbol- the device reminds of the disease and its removal is of utmost importance; the technology progresses- the need of trust in the health care personnel and in their competences. The Port improved the patients' quality of life. The study allows some reflections on the need of considering the actual and future conditions of the patient to make a shared and informed choice.

    2007-01-01

    The classical three-box paradox of Kirkpatrick (2003 J. Phys. A: Math. Gen. 36 4891) is compared to the original quantum three-box paradox of Aharonov and Vaidman (1991 J. Phys. A: Math. Gen. 24 2315). It is argued that the quantum three-box experiment is a 'quantum paradox' in the sense that it is an example of a classical task which cannot be accomplished using classical means, but can be accomplished using quantum devices. It is shown that Kirkpatrick's card game is analogous to a different game with a particle in three boxes which does not contain paradoxical features

  20. Stress-induced hypermutation as a physical property of life, a force of natural selection and its role in four thought experiments

    International Nuclear Information System (INIS)

    Hilbert, Lennart

    2013-01-01

    The independence of genetic mutation rate from selection is central to neo-Darwinian evolutionary theory. However, it has been continuously challenged for more than 30 years by experimental evidence of genetic mutation rate transiently increasing in response to stress (stress-induced hypermutation, SIH). The prominent concept of evolved evolvability (EE) explains that natural selection for strategies more competitive at evolutionary adaptation itself gives rise to mechanisms dynamically adjusting mutation rates to environmental stress. Here, we theoretically investigate the alternative (not mutually exclusive) hypothesis that SIH is an inherent physical property of all genetically reproducing life. We define stress as any condition lowering the capability of utilizing metabolic resources for genome storage and replication. This thermodynamical analysis indicates stress-induced increases in the genetic mutation rate in genome storage and in genome replication as inherent physical properties of genetically reproducing life. Further integrating SIH into an overall organismic thermodynamic budget identifies SIH as a force of natural selection, alongside death rate, replication rate and constitutive mutation rate differences. We execute four thought experiments with a non-recombinant lesion mutant strain to predict experimental observations due to SIH in response to different stresses and stress combinations. We find (1) acceleration of adaptation over models without SIH, (2) possibility of adaptation at high stresses which are not explicable by mutation in genome replication alone and (3) different adaptive potential under high growth-inhibiting versus high lethal stresses. The predictions are directly comparable to culture experiments (colony size time courses, antibacterial resistance assay and occurrence of lesion-reversion mutant colonies) and genome sequence analysis. Considering suggestions of drug-mediated disruption of SIH and attempts to target mutation

    Full Text Available Two experiments examined the benefits of unconscious thought on complex decisions (Dijksterhuis, 2004. Experiment 1 attempted to replicate and extend past research by examining the effect of providing reasons prior to rating the options. Results indicated no significant differences between the conditions. Experiment 2 attempted to replicate the findings of Dijksterhuis, Bos, Nordgren, and van Baaren (2006 and determine if a memory aid could overcome the limitations of conscious thought on complex tasks. Results revealed that a memory aid improved decisions compared to the conscious thought condition. Participants in the unconscious thought condition did not perform significantly better than did participants in the conscious thought condition.

    Historically, large items of TRU Waste, which were too large to be packaged in drums for disposal have been packaged in various sizes of custom made plywood boxes at the Savannah River Site (SRS), for many years. These boxes were subsequently packaged into large steel ''Black Boxes'' for storage at SRS, pending availability of Characterization and Certification capability, to facilitate disposal of larger items of TRU Waste. There are approximately 107 Black Boxes in inventory at SRS, each measuring some 18' x 12' x 7', and weighing up to 45,000 lbs. These Black Boxes have been stored since the early 1980s. The project to repackage this waste into Standard Large Boxes (SLBs), Standard Waste Boxes (SWB) and Ten Drum Overpacks (TDOP), for subsequent characterization and WIPP disposal, commenced in FY04. To date, 10 Black Boxes have been repackaged, resulting in 40 SLB-2's, and 37 B25 overpack boxes, these B25's will be overpacked in SLB-2's prior to shipping to WIPP. This paper will describe experience to date from this project

    Community-based studies have linked psychotic experiences (PEs) with increased risks of suicidal thoughts and behaviors (STBs). However, it is not known if these associations vary across the life course or if mental disorders contribute to these associations. To examine the temporal association between PEs and subsequent STBs across the life span as well as the influence of mental disorders (antecedent to the STBs) on these associations. A total of 33 370 adult respondents across 19 countries from the World Health Organization World Mental Health Surveys were assessed for PEs, STBs (ie, ideation, plans, and attempts), and 21 DSM-IV mental disorders. Discrete-time survival analysis was used to investigate the associations of PEs with subsequent onset of STBs. Prevalence and frequency of STBs with PEs, and odds ratios and 95% CIs. Of 33 370 included participants, among those with PEs (n = 2488), the lifetime prevalence (SE) of suicidal ideation, plans, and attempts was 28.5% (1.3), 10.8% (0.7), and 10.2% (0.7), respectively. Respondents with 1 or more PEs had 2-fold increased odds of subsequent STBs after adjusting for antecedent or intervening mental disorders (suicidal ideation: odds ratio, 2.2; 95% CI, 1.8-2.6; suicide plans: odds ratio, 2.1; 95% CI, 1.7-2.6; and suicide attempts: odds ratio, 1.9; 95% CI, 1.5-2.5). There were significant dose-response relationships of number of PE types with subsequent STBs that persisted after adjustment for mental disorders. Although PEs were significant predictors of subsequent STB onset across all life stages, associations were strongest in individuals 12 years and younger. After adjustment for antecedent mental disorders, the overall population attributable risk proportions for lifetime suicidal ideation, plans, and attempts associated with temporally prior PEs were 5.3%, 5.7%, and 4.8%, respectively. Psychotic experiences are associated with elevated odds of subsequent STBs across the life course that cannot be

    In early 2007, SLAC was faced with a shortage of both electrical power and cooling in the main computer building, at the same time that the BaBar collaboration needed a new cluster of 250 batch machines installed. A number of different options were explored for the expansion. Provision of additional electrical power to the building was estimated to take one to two years, and cost several million dollars; additional cooling was even worse. Space in a Silicon Valley co-location facilities was reasonable on a one-year timescale, but broke even in costs by the end of three years, and were more expensive after that. There were also unresolved questions about the affects of additional latency from an offsite compute cluster to the onsite disk servers. The option of converting existing experimental hall space into computer space was estimated at one year, with uncertain availability. An option to aggressively replace several existing clusters with more power-efficient equipment was studied closely, but was disruptive to continued operations, expensive, and didn't provide any additional headroom. Finally, the installation of a Sun Project Blackbox (PBB) unit was selected as providing the capacity on a timescale of six months for a reasonable cost with minimal disruption to service. SLAC obtained and installed a beta unit and have been running it in production since September 2007. The experiences described are with the Early Access version of the PBB. The production version of the box has engineering changes based in part on our experiences

    There are no unique boxing diseases but certain factors contributing to the spread of illnesses apply strongly to the boxer, coach, and the training facility. This article examines the nature of the sport of boxing and its surrounding environment, and the likelihood of spread of infection through airborne, contact, or blood-borne routes of transmission. Evidence from other sports such as running, wrestling, and martial arts is included to help elucidate the pathophysiologic elements that could be identified in boxers.

    In 1986, a surgeon who, as an amateur boxer himself was concerned with boxers' health, approached a pioneering Parisian neuroimaging unit. Thus began a study in close cooperation with the French Boxing Federation, spanning 25 years. In a first series of 52 volunteer boxers (13 amateurs and 39 professionals), during which MRI gradually replaced computed tomography, ten risk factors were identified, which notably included boxing style: only one of 40 "stylists" with a good boxing technique had cortical atrophy (4.5 %), compared to 15 % of "sloggers". Changes to the French Boxing Federation rules placed the accent on medical prevention. The second series, of 247 boxers (81 amateurs and 266 professionals), showed a clear improvement, as lesions were suspected in 14 individuals, of which only 4 (1.35 %) were probably due to boxing. The third and fourth series were part of a protocol called "Brain-Boxing-Ageing", which included 76 boxers (11 having suffered KOs) and 120 MRI scans, with reproducible CT and MRI acquisitions (9 sequences with 1.5 T then 3 T, and CT). MRI anomalies secondary to boxing were found in 11 % of amateurs and 38 % of professionals (atrophy, high vascular T2 signal areas, 2 cases of post-KO subdural bleeding). CT revealed sinus damage in 13 % of the amateurs and 19 % of the professionals. The risk of acute and chronic facial and brain damage was underline, along with detailed precautionary measures (organization of bouts, role of the referee and ringside doctor, and application of French Boxing Federation rules).

    Professional boxing has done an admirable job in promoting safety standards in its particular sport. However, injuries occur during the normal course of competition and, unfortunately, an occasional life-threatening emergency may arise. Although most common medical emergencies in boxing are injuries from closed head trauma, in this article those infrequent but potentially catastrophic nonneurologic conditions are reviewed along with some less serious emergencies that the physician must be prepared to address.

    Chandler, Jesse J; Pronin, Emily

    2012-04-01

    In two experiments, we tested for a causal link between thought speed and risk taking. In Experiment 1, we manipulated thought speed by presenting neutral-content text at either a fast or a slow pace and having participants read the text aloud. In Experiment 2, we manipulated thought speed by presenting fast-, medium-, or slow-paced movie clips that contained similar content. Participants who were induced to think more quickly took more risks with actual money in Experiment 1 and reported greater intentions to engage in real-world risky behaviors, such as unprotected sex and illegal drug use, in Experiment 2. These experiments provide evidence that faster thinking induces greater risk taking.

  17. The BOXES Methodology Black Box Dynamic Control

    2012-01-01

    Robust control mechanisms customarily require knowledge of the system’s describing equations which may be of the high order differential type.  In order to produce these equations, mathematical models can often be derived and correlated with measured dynamic behavior.  There are two flaws in this approach one is the level of inexactness introduced by linearizations and the other when no model is apparent.  Several years ago a new genre of control systems came to light that are much less dependent on differential models such as fuzzy logic and genetic algorithms. Both of these soft computing solutions require quite considerable a priori system knowledge to create a control scheme and sometimes complicated training program before they can be implemented in a real world dynamic system. Michie and Chambers’ BOXES methodology created a black box system that was designed to control a mechanically unstable system with very little a priori system knowledge, linearization or approximation.  All the method need...

    In many temperate perennial plants, floral transition is initiated in the first growth season but the development of flower is arrested during the winter to ensure production of mature flowers in the next spring. The molecular mechanisms of the process remain poorly understood with few well-characterized regulatory genes. Here, a MADS-box gene, named as TrMADS3, was isolated from the overwintering inflorescences of Taihangia rupestris, a temperate perennial in the rose family. Phylogenetic analysis reveals that TrMADS3 is more closely related to the homologs of the FLOWERING LOCUS C lineage than to any of the other MIKC-type MADS-box lineages known from Arabidopsis. The TrMADS3 transcripts are extensively distributed in inflorescences, roots, and leaves during the winter. In controlled conditions, the TrMADS3 expression level is upregulated by a chilling exposure for 1 to 2 weeks and remains high for a longer period of time in warm conditions after cold treatment. In situ hybridization reveals that TrMADS3 is predominantly expressed in the vegetative and reproductive meristems. Ectopic expression of TrMADS3 in Arabidopsis promotes seed germination on the media containing relatively high NaCl or mannitol concentrations. These data indicate that TrMADS3 in a perennial species might have its role in both vegetative and reproductive meristems in response to cold.

  19. Thoughts on Reflection (Editorial

    2010-06-01

    Evidence in Practice section uses a standardized format enabling practitioners to share their experience of integrating research evidence into their practice. The final section of these brief articles asks the writers to reflect on their experience. Although it is not research, the individual reflection allies with what Schön (1983 called “reflection on action” and such reflections over time form a practical, tacit knowledge that we use to inform our work. Within this section of the journal, we hope readers will become more aware of how different types of evidence can be integrated into real‐world decision making. Not everything requires a full blown research study, and this section allows readers to see what other practitioners are doing, and in turn it should enable them to reflect upon what they are doing in their own practice. Being aware of situations where things may or may not have worked, and reflecting on the reasons why, brings together our sense of critical thought and practical experience that go a long way in filling the “librarian observed” and “professional judgements” parts of the EBLIP definition (Booth and Brice 2004. Acquiring professional knowledge does not end when we complete a graduate program, or have a certain number of years experience under our belts. It needs to be continually and consciously cultivated via reflection on our practice, our research, and simply what works and why. Research knowledge only takes us so far. People often ask me, “What do I do when there is no evidence? Or when the research evidence is weak?” Does this stop us from moving ahead? No. A decision still needs to be made. Evidence based practice is not only about acting when there is good evidence. Enhancing our professional judgments via a career built on analytical reflection, will provide knowledge that goes a long way towards making difficult decisions a little bit easier; even (or perhaps, especially in the cases when there is already a large body of

    2009-10-01

    In boxing, along with a few other sports, trauma is inherent to the nature of the sport; therefore it is considered a high-risk sport for ocular injuries. The long-term morbidity of ocular injuries suffered by boxers is difficult to estimate due to the lack of structured long-term follow-up of these athletes. Complications of blunt ocular trauma may develop years after the athlete has retired from the ring and is no longer considered to be at risk for boxing-related injuries. This article describes the wide range of eye injuries a boxer can sustain, and their immediate and long-term clinical management.

    In this study a novel High Performance Liquid Chromatography for the assay of nystatin in oral and vaginal tablets were optimized and validated using Box-Behnken experimental design. The method was performed in the isocratic mode on a RP-18 column (30 °C) using a mobile phase consisting of ammonium acetate 0.05 M buffer/ Methanol mixture (30:70) and a flow-rate of 1.0 mL/min. The specificity, linearity, precision, accuracy, LOD and LOQ of the method were validated. The method was linear over the range of 5-500 µg/mL with an acceptable correlation coefficient (r(2) = 0.9996). The method's limit of detection (LOD) and quantification (LOQ) were 0.01 and 0.025 µg/mL respectively. The results indicate that this validated method can be used as an alternative method for assay of nystatin.

    Full Text Available There is high unmet need for family planning (FP in Uganda as well as high contraceptive discontinuation rates. These contribute to the high fertility rates that in part are due to unplanned pregnancies. There are gaps in knowledge about experiences that couples go through while using contraceptives in their lives. This study explored women's experiences during the course of their contraceptive use.We conducted a qualitative study involving 30 women who had used modern contraception for at least one year in Wakiso district, central Uganda. We used in-depth interviews to obtain their personal accounts. Index women were approached through health officers at four health centres in the district. All ethical approvals and informed consent were obtained. We used conventional content analysis; identifying codes through open coding, on which basis categories were developed and grouped into overarching themes.Women's accounts were summarised in the following themes: negative experiences with modern contraceptive use, motivation to continue using FP in spite of these negative experiences, the role of influential people, and discontinuation of use. Negative accounts dominated the experiences of most women but they expressed strong desire to continue using modern contraception even amidst all challenges. Health workers emerged as the most influential people that played a vital role in women's decisions.Varied negative experiences with modern contraception and misperceptions exist amidst a determination to continue use. Partner engagement, health service strengthening to improve side effects management and health worker skills, and engaging older women that have successfully used contraception as community champions, are potential strategies to support women's contraceptive decisions.

    Objectives: To investigate the prevalence of ocular injuries in a large population of boxers over a period of 16 years, in particular, the most severe lesions that may be vision threatening. Methods: Clinical records of the medical archive of the Italian Boxing Federation were analysed. A total of 1032 boxers were examined from February 1982 to October 1998. A complete ophthalmological history was available for 956, who formed the study population (a total of 10 697 examinations). The following data were collected: age when started boxing; duration of competitive boxing career (from the date of the first bout); weight category; a thorough ocular history. The following investigations were carried out: measurement of visual acuity and visual fields, anterior segment inspection, applanation tonometry, gonioscopy, and examination of ocular fundus. Eighty age matched healthy subjects, who had never boxed, formed the control group. Results: Of the 956 boxers examined, 428 were amateur (44.8%) and 528 professional (55.2%). The median age at first examination was 23.1 (4.3) years (range 15–36). The prevalence of conjunctival, corneal, lenticular, vitreal, ocular papilla, and retinal alterations in the study population was 40.9% compared with 3.1% in the control group (p⩽0.0001). The prevalence of serious ocular findings (angle, lens, macula, and peripheral retina alterations) was 5.6% in boxers and 3.1% in controls (NS). Conclusions: Boxing does not result in a higher prevalence of severe ocular lesions than in the general population. However, the prevalence of milder lesions (in particular with regard to the conjunctiva and cornea) is noteworthy, justifying the need for adequate ophthalmological surveillance. PMID:15665199

  13. Manic thinking: independent effects of thought speed and thought content on mood.

    Science.gov (United States)

    Pronin, Emily; Wegner, Daniel M

    2006-09-01

    This experiment found that the speed of thought affects mood. Thought speed was manipulated via participants' paced reading of statements designed to induce either an elated or a depressed mood. Participants not only experienced more positive mood in response to elation than in response to depression statements, but also experienced an independent increase in positive mood when they had been thinking fast rather than slow--for both elation and depression statements. This effect of thought speed extended beyond mood to other experiences often associated with mania (i.e., feelings of power, feelings of creativity, a heightened sense of energy, and inflated self-esteem or grandiosity).

    Highlights: • Glove box is a leak tight, safety related structure used for handling radiotoxic materials. • To study the seismic performance of a freestanding glove box, extensive shake table testing has been carried out. • Glove box maintained structural integrity and leak tightness up to design basis earthquake loading. • Detailed three-dimensional finite element model of the structure is developed and analyzed by using direct time integration methods. • Simplified numerical method is proposed and successfully applied, to quickly estimate sliding displacement and determine upper bounds for it. - Abstract: In a nuclear fuel cycle facility, radiotoxic materials are being handled in freestanding leak tight enclosures called glove boxes (GBs). These glove boxes act as a primary confinement for the radiotoxic materials. Glove boxes are designed as per codal requirements for class I component. They are designed to withstand extreme level of earthquake loading with a return period of 10,000 years. To evaluate seismic performance of the glove box, there is a need to check the stability (sliding and overturning), structural integrity (stresses and strains) and leak tightness under earthquake loading. Extensive shake table experiments were conducted on a single standalone glove box. Actual laboratory conditions were simulated during testing to check the response. After extensive shake table testing, glove box structure was also analyzed using finite element (FE) software. Detailed three-dimensional model of glove box structure was developed and analyzed using nonlinear time history method. It was observed that finite element methods could be utilized to accurately predict dynamic response of glove box structure.

    The opto-box is a custom mini-crate for housing optical modules, which process and transfer optoelectronic data. Many novel solutions were developed for the custom design and manufacturing. The system tightly integrates electrical, mechanical, and thermal functionality into a small package of size 35x10x8 cm$^{3}$. Special attention was given to ensure proper shielding, grounding, cooling, high reliability, and environmental tolerance. The custom modules, which incorporate Application Specific Integrated Circuits (ASICs), were developed through a cycle of rigorous testing and redesign. In total, fourteen opto-boxes have been installed and loaded with modules on the ATLAS detector. They are currently in operation as part of the LHC run 2 data read-out chain.

    The three-box problem is a gedankenexperiment designed to elucidate some interesting features of quantum measurement and locality. A particle is prepared in a particular superposition of three boxes, and later found in a different (but nonorthogonal) superposition. It was predicted that appropriate 'weak' measurements of particle position in the interval between preparation and post-selection would find the particle in two different places, each with certainty. We verify these predictions in an optical experiment and address the issues of locality and of negative probability

    The Smart Medicine Box is successfully designed in helping the introvert patients taking their medicine without help of others. This project is to develop a robotic device that can assist patient to take medicine alone by implementing an IOT apps system for controlling the Smart Medicine Box where it will overcome an emotional disturbance experience by the introvert patients. There are four sensors such as PIR, IR, temperature and ultrasonic sensors use for the project. The purpose of PIR sensor is to detect hand movement near the device, while IR sensor is to detect the line follower on the floor. The LM 35 acts as the detection of the temperature inside the box and the ultrasonic acts as the detection of the obstacle in front of the device. The MIT Apps Invention 2 is used to develop an apps and collect the data from sensors through Arduino microcontroller. A proof of concept design has implemented and demonstrated successfully.

    In spite of access to behavioral and biomedical HIV prevention strategies, HIV transmission occurs. For HIV-serodiscordant couples, prevention programs can be tailored to address individual and couples' needs to preserve their relationship while minimizing HIV risk. Programs for serodiscordant couples may benefit from learning from experiences of couples who transmit HIV. We conducted 20 individual in-depth interviews with 10 initially HIV-serodiscordant couples who transmitted HIV during prospective follow-up at a peri-urban research site in Thika, Kenya. Data were analyzed inductively to identify situations that led to prevention failure and coping mechanisms. Inconsistent condom use driven by low HIV risk perception and alcohol use often preceded seroconversion while persistent blame frequently hindered couples' communication soon after seroconversion. In this emerging era of antiretroviral-based HIV prevention, couples' counseling can capitalize on opportunities to foster a supportive environment to discuss initiation and adherence to time-limited pre-exposure prophylaxis and lifelong antiretroviral therapy, in addition to strategies to reduce alcohol use, diffuse blame, and use condoms.

    Full Text Available Heo Joon is one of the best-known physicians of the Chosun Dynasty, the last imperial dynasty (1392~1910 of Korea. He had served King Seonjo during his practice, and has produced many publications on medicine. Then, how did he actually treat the patients? So far, other than the case when he treated Gwanghaegun’s smallpox, it is not clearly known how and when he attended and treated the ill. In his most famous book, the Treasured Mirror of Eastern Medicine (TMEM, he details the physiopathological mechanisms, diagnoses, treatments or prescriptions, and treatment cases, however, it is not clear if they’re from his own clinical experiences. Nevertheless, based on the written method, the original information is reconstituted according to its respective editors of the TMEM, a particular case being included may be considered as an agreement and acceptance of an actual treatment executed. This research analyzes what type of medicinal theory that the main writer Heo Joon employed in his real treatments, as well as how he diagnosed and treated diseases. After analyzing the complete series of the TMEM, we found a total of 301 clinical cases. Here, one may wonder, why does the Section of Inner and External Bodily Elements, that deal with diseases and the structure of the body, have far outnumber cases than the Section of Miscellaneous Disorders? Why does the TMEM introduce the various types of disease experiences and treatment cases, medical cases, simple treatments, nurturing life, materia medica, and also include supernatural phenomena? Why does the TMEM include the experiences and cases from the book published in the Song (宋, Jin (金, Yuan (元 dynasty of China, moreover in the Ming (明 Dynasty of its time. These questions can be answered to the extent that Heo Joon and the others who participated in completing the book sought to justify the new clinical medicine practices, and because it had to be acceptable to the Confucius beliefs which

    Full text: Queensland-based Hydrasyst wants to take its motto of 'Do more with less' into the greywater sector with a new water recycling and energy recovery technology launched in November, called The Grey Box. The company is initially targeting large industrial laundries as they are major generators of greywater and heavy energy users, but it has ambitions well beyond that. The average commercial laundry consumes 1-5ML of water a week, using about 16 litres for every 1kg of clothing washed. Hydrasyst director Stephen Balemi said The Grey Box can slash the volume by 80 per cent. While he was reluctant to disclose too much technical detail, he claimed it is the only technology serving the $1 billion a year laundry sector that combines microfiltration / ultrafiltration membrane technology and energy reduction components. The heart of the system is a ceramic hollow fibre membrane. Balemi said it produces higher filtrate quality than competitors, meaning the recycled water can be reused more often, and can process feed water of up to 70°C compared to typical ultrafiltration membranes that cap out at about 38°C. This means the recycled water can be reused at higher temperatures, with the heat in it recovered by a precise steam heater built into The Grey Box. “As an overall measure, it saves 80 per cent of the water that is processed and saves 20 per cent of the energy,” Balemi said. Four systems have already been installed, with one going into a large commercial laundry in south Queensland and another to AMP's state-of-the-art 6 Green Star building in Brisbane. “We can modify them slightly to suit the industry, depending on the quality of raw water they are trying to recycle and also depending on the size of the project,,” said Balemi. Where many organisations build systems to specification, The Grey Box is offered in three standard sizes: the HY20 (20kL per day, based on a 10 hour day), HY80 (80kL per day) and HY130 (130kL per day). They can be used

    This article investigates 2 possible antecedents of thought confidence and explores the effects of confidence induced before or during ad exposure. The results of the experiments indicate that both consumers' dispositional optimism and spokesperson attractiveness have significant effects on consumers' confidence in thoughts that are generated after viewing the advertisement. Higher levels of thought confidence will influence the quality of the thoughts that people generate, lead to either positively or negatively polarized message processing, and therefore induce better or worse advertising effectiveness, depending on the valence of thoughts. The authors posit the belief-polarization hypothesis to explain these findings.

    In this study, novel wood combustion aging experiments performed at different temperatures (263 and 288 K) in a ˜ 7 m3 smog chamber were modelled using a hybrid volatility basis set (VBS) box model, representing the emission partitioning and their oxidation against OH. We combine aerosol-chemistry box-model simulations with unprecedented measurements of non-traditional volatile organic compounds (NTVOCs) from a high-resolution proton transfer reaction mass spectrometer (PTR-MS) and with organic aerosol measurements from an aerosol mass spectrometer (AMS). Due to this, we are able to observationally constrain the amounts of different NTVOC aerosol precursors (in the model) relative to low volatility and semi-volatile primary organic material (OMsv), which is partitioned based on current published volatility distribution data. By comparing the NTVOC / OMsv ratios at different temperatures, we determine the enthalpies of vaporization of primary biomass-burning organic aerosols. Further, the developed model allows for evaluating the evolution of oxidation products of the semi-volatile and volatile precursors with aging. More than 30 000 box-model simulations were performed to retrieve the combination of parameters that best fit the observed organic aerosol mass and O : C ratios. The parameters investigated include the NTVOC reaction rates and yields as well as enthalpies of vaporization and the O : C of secondary organic aerosol surrogates. Our results suggest an average ratio of NTVOCs to the sum of non-volatile and semi-volatile organic compounds of ˜ 4.75. The mass yields of these compounds determined for a wide range of atmospherically relevant temperatures and organic aerosol (OA) concentrations were predicted to vary between 8 and 30 % after 5 h of continuous aging. Based on the reaction scheme used, reaction rates of the NTVOC mixture range from 3.0 × 10-11 to 4. 0 × 10-11 cm3 molec-1 s-1. The average enthalpy of vaporization of secondary organic aerosol

    Continuity of health care is a goal to be achieved. Most are for it. Many claim to provide it. But how do we know we have it? What are the key features of continuity? While dictionaries do not define the phrase "continuity of health care," we do find definitions of "continuity." The Oxford English Dictionary, Second Edition, includes in its definitions: "the state or quality of being uninterrupted in sequence or succession, or in essence or idea; connectedness, coherence, unbroken..." Stedman's Medical Dictionary includes: "absence of interruption, a succession of parts intimately united..." These definitions stress an uninterrupted succession and include the concept that there needs to be a connection to the parts. Without that connection, continuity, in health care delivery or elsewhere, does not exist.

    It is imagined that our World is being examined from a similar world which is moving relative to us with a velocity greater than that of light. The two worlds are supposed to be similar in that the particles in each appear to any observer in that world to have real measurable properties. However, the enormous relative velocity so distorts the observations that each world makes on the other that the squares of certain real quantities appear to the other observer to be negative. Neglect of this fact has led to the erroneous belief that a free charged tachyon would emit Cherenkov radiation and that the existence of tachyons would lead to logical paradoxes. (author)

    The use of microclimate boxes to protect vulnerable panel paintings is, therefore, not a new phenomenon of the past two or three decades. Rather, it has been a concern for conservators and curators to protect these objects of art at home and in transit since the end of the nineteenth century....... The increased number of travelling exhibitions in recent years has heightened the need to protect paintings during circulation (Thomson 1961; Mecklenburg 1991). The use and design of microclimate boxes have been evolving since 1892. These boxes may be divided into three broad groups: those using an active...... buffer material to stabilize the internal RH, a more recent box containing no added buffer material, and, in recent times, boxes with an altered gas content. Another concern is the appearance (aesthetics) of the box....

  15. From intrusive to oscillating thoughts.

    Peirce, Anne Griswold

    2007-10-01

    This paper focused on the possibility that intrusive thoughts (ITs) are a form of an evolutionary, adaptive, and complex strategy to prepare for and resolve stressful life events through schema formation. Intrusive thoughts have been studied in relation to individual conditions, such as traumatic stress disorder and obsessive-compulsive disorder. They have also been documented in the average person experiencing everyday stress. In many descriptions of thought intrusion, it is accompanied by thought suppression. Several theories have been put forth to describe ITs, although none provides a satisfactory explanation as to whether ITs are a normal process, a normal process gone astray, or a sign of pathology. There is also no consistent view of the role that thought suppression plays in the process. I propose that thought intrusion and thought suppression may be better understood by examining them together as a complex and adaptive mechanism capable of escalating in times of need. The ability of a biological mechanism to scale up in times of need is one hallmark of a complex and adaptive system. Other hallmarks of complexity, including self-similarity across scales, sensitivity to initial conditions, presence of feedback loops, and system oscillation, are also discussed in this article. Finally, I propose that thought intrusion and thought suppression are better described together as an oscillatory cycle.

    Fatalities in boxing are most often due to traumatic brain injury that occurs in the ring. In the past 30 years, significant improvements in ringside and medical equipment, safety, and regulations have resulted in a dramatic reduction in the fatality rate. Nonetheless, the rate of boxing-related head injuries, particularly concussions, remains unknown, due in large part to its variability in clinical presentation. Furthermore, the significance of repeat concussions sustained when boxing is just now being understood. In this article, we identify the clinical manifestations, pathophysiology, and management of boxing-related head injuries, and discuss preventive strategies to reduce head injuries sustained by boxers.

    The Accelerator Control System (ACSYS) at Fermilab has evolved to enable this relatively large control system to be encapsulated into a 'box' such as a laptop. The goal was to provide a platform isolated from the 'online' control system. This platform can be used internally for making major upgrades and modifications without impacting operations. It also provides a stand-alone environment for research and development including a turnkey control system for collaborators. Over time, the code base running on Scientific Linux has enabled all the salient features of the Fermilab's control system to be captured in an off-the-shelf laptop. The anticipated additional benefits of packaging the system include improved maintenance, reliability, documentation, and future enhancements. (authors)

    Full Text Available It is hard to provide an unequivocal answer to the question of whether or not thought suppression is effective. Two thought suppression paradigms - the “white bear” paradigm and the think/no-think paradigm - give mixed results. Generally, “white bear” experiments indicate that thought suppression is counterproductive, while experiments in the think/no-think paradigm suggest that it is possible to effectively suppress a thought. There are also alternative methods used to study thought suppression, for instance the directed forgetting paradigm or the Stroop task. In the article, I describe the research methods used to explore thought suppression efficacy. I focus on the “white bear” and the think/no-think paradigms and discuss theories proposed to explain the results obtained. I also consider the internal and external validity of the methods used.

    The present invention provides a method for measuring the entire length of a channel box of a fuel assembly of a BWR type reactor. Namely, four sensors are used as one set that generate ultrasonic waves from oblique upper portion, oblique lower portion, upper portion and lower portion of the channel box respectively. The distances between the four sensors and each of the portions of the channel box are measured respectively for both of a reference member and a member to be measured. The entire length of the channel box is measured by calculating the measured values and the angles of the obliquely disposed sensors according to a predetermined formula. According to the method of the present invention, the inclination of the channel box to be measured can be corrected. In addition, accuracy of the measurement is improved and the measuring time is saved as well as the measuring device and operation can be simplified. (I.S.)

  7. Propositions toward the development of a psychological theory of thought

    Shadrikov, Vladimir D.

    2017-03-01

    Full Text Available Thought is considered a psychological concept associated with an individual’s mental ex- istence. It is apparent that a great deal of research has been focused on thought as an area of study. however, there is no psychological theory of thought which provides an expla- nation for its nature and structural organization. So far, researchers have mainly looked at the ways this concept is expressed, rather than investigating what it actually is. In this study, however, based on studies of the functions of the psyche, mental processes, and the neurophysiological bases of mental activity, thought is identified as a need-emotion- intentional substance existing in the human being’s inner world. In keeping with this understanding of thought, the hypothesis that thought generation is caused by desire and experience (feeling and emotion is put forward. An individual’s thought is linked to his behavior or motivation for activity, and is followed by an emotional experience. The process of thought generation is regarded through the mechanism of behavioral motiva- tion. The primary purpose of this mechanism is to define the qualities of the external objects that serve for need satisfaction and functionality in individuals. The ability to generate thoughts is a feature of thinking related to an individual’s mental ability or frame of mind. From this standpoint, a person’s mentality is considered to be the capacity of the individual to generate thoughts and work through thoughts. It is shown that the abil- ity to generate thoughts and establish relationships within a stream of consciousness is characteristic of human intelligence. Some basic propositions toward a development of a psychological theory of thought are introduced.

    Full Text Available This paper aims to show that the problem of personal identity is a fundamental question of the classical Indian thought. Usually we tend to think that personal identity is a Western philosophical subject, and so we tend to forget the significance of the Self (Atman in Hinduism and even in Buddhism. The author shows how the Indian thought approached the question of personal identity and which was the singular solution outlined in the work consensually attributed to Gotama, the Buddha.

  10. On social death: ostracism and the accessibility of death thoughts.

    Science.gov (United States)

    Steele, Caroline; Kidd, David C; Castano, Emanuele

    2015-01-01

    Being rejected, excluded, or simply ignored is a painful experience. Ostracism researchers have shown its powerful negative consequences (Williams, 2007), and sociologists have referred to such experiences as social death (Bauman, 1992). Is this is just a metaphor or does being ostracized make death more salient in people's minds? An experiment was conducted in which participants experienced ostracism or inclusion using the Cyberball manipulation, and the accessibility of death-related thoughts was measured via a word-stem completion puzzle. Results showed enhanced death-thought accessibility in the ostracism condition, as well as a negative effect of dispositional self-esteem on the accessibility of death-related thoughts.

    Marino-Carper, Teresa; Negy, Charles; Burns, Gillian; Lunt, Rachael A

    2010-09-01

    The current study examined the effects of a psychoeducational intervention designed to target thought-action fusion (TAF) on TAF, thought suppression, and responsibility cognitions. 139 undergraduate students (25 male; 114 female) who were relatively high in TAF with respect to their peers served as participants. Immediately following intervention, individuals who had received psychoeducation regarding TAF reported significantly lower morality TAF scores than individuals who had received psychoeducation regarding thoughts in general and individuals in the control group. At the two-week follow-up assessment, the likelihood TAF scores of those who had received psychoeducation regarding TAF were significantly lower than those of the control group. In addition, the group that received psychoeducation regarding TAF was the only group that did not experience a significant increase in thought suppression from baseline to post-intervention, and was also the only group to experience an increase in both frequency of and belief in low-responsibility thoughts from baseline to follow-up. Implications are discussed. (c) 2010 Elsevier Ltd. All rights reserved.

  12. On the channel box for the fuel bundle of BWR

    1976-01-01

    Channel boxes play the important roles of making coolant flow uniform and protecting fuel rods as the component of fuel assemblies for BWRs. About ten years ago, the domestic production of channel boxes was first investigated, and now, the original technology has been developed, and the channel boxes sufficiently satisfying the required quality can be produced. The actual experience by being charged in reactors has also been accumulated. At present, the supply capacity is almost sufficient to meet the domestic demand, and the future increase of demand can be dealt with promptly. The channel boxes are made of Zircaloy-4 plates which are favorable in view of neutron absorption, and are the boxes with 138 mm hollow square section, 2 mm thickness, and 4240 mm length. Two channels were welded together and made into a box. In order to eliminate the residual stress caused during the manufacture, high temperature heating with an electric furnace was adopted. The measurement of dimensions and the inspection of appearance of the channel boxes after irradiation proved that they were rather superior to imported ones. The production processes, the system for the quality guarantee, and the quality control in the Kobe Steel Ltd. are explained. The test and inspection are carried out at the time of accepting outside products, before starting the production, after the completion of longitudinal welding and after the completion of production.

    The crystal structure of HMGB1 box A bound to an unmodified AT-rich DNA fragment is reported at a resolution of 2 Å. A new mode of DNA recognition for HMG box proteins is found in which two box A domains bind in an unusual configuration generating a highly kinked DNA structure. High-mobility group protein 1 (HMGB1) is an essential and ubiquitous DNA architectural factor that influences a myriad of cellular processes. HMGB1 contains two DNA-binding domains, box A and box B, which have little sequence specificity but have remarkable abilities to underwind and bend DNA. Although HMGB1 box A is thought to be responsible for the majority of HMGB1–DNA interactions with pre-bent or kinked DNA, little is known about how it recognizes unmodified DNA. Here, the crystal structure of HMGB1 box A bound to an AT-rich DNA fragment is reported at a resolution of 2 Å. Two box A domains of HMGB1 collaborate in an unusual configuration in which the Phe37 residues of both domains stack together and intercalate the same CG base pair, generating highly kinked DNA. This represents a novel mode of DNA recognition for HMGB proteins and reveals a mechanism by which structure-specific HMG boxes kink linear DNA.

    The evolution of BHs in 'confining boxes' is interesting for a number of reasons, particularly because it mimics some aspects of anti-de Sitter spacetimes. These admit no Cauchy surface and are a simple example of a non-globally hyperbolic spacetime. We are here interested in the potential role that boundary conditions play in the evolution of a BH system. For that, we imprison a binary BH in a box, at which boundary we set mirror-like boundary conditions.

  17. The lithium vapor box divertor

    International Nuclear Information System (INIS)

    Goldston, R J; Schwartz, J; Myers, R

    2016-01-01

    It has long been recognized that volumetric dissipation of the plasma heat flux from a fusion power system is preferable to its localized impingement on a material surface. Volumetric dissipation mitigates both the anticipated very high heat flux and intense particle-induced damage due to sputtering. Recent projections to a tokamak demonstration power plant suggest an immense upstream parallel heat flux, of order 20 GW m −2 , implying that fully detached operation may be a requirement for the success of fusion power. Building on pioneering work on the use of lithium by Nagayama et al and by Ono et al as well as earlier work on the gas box divertor by Watkins and Rebut, we present here a concept for a lithium vapor box divertor, in which lithium vapor extracts momentum and energy from a fusion-power-plant divertor plasma, using fully volumetric processes. At the high powers and pressures that are projected this requires a high density of lithium vapor, which must be isolated from the main plasma in order to avoid lithium build-up on the chamber walls or in the plasma. Isolation is achieved through a powerful multi-box differential pumping scheme available only for condensable vapors. The preliminary box-wise calculations are encouraging, but much more work is required to demonstrate the practical viability of this scheme, taking into account at least 2D plasma and vapor flows within and between the vapor boxes and out of the vapor boxes to the main plasma.

    1989-01-01

    A glove box used at nuclear facilities must confine radioactive materials. High airtightness and negative internal pressure are used to prevent leaks. The allowable leakage rate of air is 0.1% vol/hr or less at the pre-service inspection. The negative pressure value is kept at - 30 mm H 2 O in normal operation. The glove box structural strength and its confinement reliability during an earthquake are major concerns. The verification of aseismic analysis methods and assumptions for a glove box are thus of great importance. Data on the dynamic behavior of giant glove boxes was recently obtained in large shaker experiments. This paper describes these experimental results and the appropriateness of aseismic analysis methods used in current design

    With the aim to test an compare some properties of materials and common geometries that are used for designing solar cookers, water heaters, etc. we have made a solar hot box with two similar compartments. In the present study this hot box has been used for, (a) comparing the behavior of a metallic slab filled with a phase change material for short term heat storage, with a conventional absorbing sheet, (b) the use of a selectively coated, as compared to a normal black painted, cooking pot, and (c) for finding the overall heat loss coefficient and thermal capacity of the box. Experiments with the solar hot box will yield valuable information on solar systems that are to be constructed. Besides its use for research this multi-purpose device has been used both to pasteurize up to 14-16 l of water and for cooking. (author)

  2. Dry boxes and inert atmosphere techniques

    International Nuclear Information System (INIS)

    Bartak, D.E.

    1987-01-01

    Practitioners need to conduct experiments with molten salts in an inert atmosphere owing to the chemical reactivity of these media. Most fused salt solvent systems show reactivity to water and/or oxygen, which results in significant chemical changes in the properties of these solvents. Although several studies on the nature of an oxygen/oxide electrode in this melt have been reported, the reactions have not been fully understood because of apparent water contamination in many cases. Nitrate melt systems are also hygroscopic; for example, the LiNO 3 -KNO 3 eutectic (177 0 C) absorbs water to at least 0.2% by weight. The result is that the electrochemistry of heavier, electropositive metal ions has been significantly altered. In addition, trace amounts of water have been shown to significantly affect the oxygen-oxide redox chemistry in NaNO 3 -KNO 3 melts (250 0 C). The haloaluminates, which include AlCl 3 -NaCl (175 0 C), as well as AlCl 3 -organic salt binaries are particularly sensitive to the presence of both oxygen and moisture. Oxygen is a strong oxidant in the fused hydroxide systems with formation of superoxide ion from either oxide or water. This chapter describes general, inert atmosphere techniques which can be used by the molten salt experimentalist. Because of the limitations of volatility, vacuum manipulations are not considered. Rather, the use of glove boxes, glove bags, and inert bench-top techniques are discussed. The areas covered are: glove box and bag equipment, operation and maintenance of glove boxes and glove bags, and common operations conducted inside glove boxes

    Although a popular endeavor, boxing has fallen under increased scrutiny because of its association with traumatic brain injury. However, few studies have investigated the overall epidemiology of boxing injuries from representative samples, and no study has ever documented the incidence of injuries in female boxers. This study is a review of professional boxing data from the state of Nevada from September 2001 through March 2003. Medical and outcome data for all professional boxing matches occurring in Nevada between September 2001 and March 2003 (n = 524 matches) were analyzed on the basis of a pair-matched, case-control design. Cases were boxers who received an injury during the boxing matches. Boxers who were not injured served as control subjects. Both conditional and unconditional logistic regression models were used to assess risk factors for injury. The overall incidence rate of injury was 17.1 per 100 boxer-matches, or 3.4 per 100 boxer-rounds. Facial laceration accounted for 51% of all injuries, followed by hand injury (17%), eye injury (14%), and nose injury (5%). Male boxers were significantly more likely than female boxers to receive injuries (3.6 versus 1.2 per 100 boxer-rounds, P = 0.01). Male boxing matches also ended in knockouts and technical knockouts more often than did female matches (P boxing matches is high, particularly among male boxers. Superficial facial lacerations are the most common injury reported. Male boxers have a higher rate of knockout and technical knockouts than female boxers. Further research is necessary to determine the outcomes of injury, particularly the long-term neurologic outcome differences between sexes.

  6. Divergence of recently duplicated M{gamma}-type MADS-box genes in Petunia.

    2010-02-01

    The MADS-box transcription factor family has expanded considerably in plants via gene and genome duplications and can be subdivided into type I and MIKC-type genes. The two gene classes show a different evolutionary history. Whereas the MIKC-type genes originated during ancient genome duplications, as well as during more recent events, the type I loci appear to experience high turnover with many recent duplications. This different mode of origin also suggests a different fate for the type I duplicates, which are thought to have a higher chance to become silenced or lost from the genome. To get more insight into the evolution of the type I MADS-box genes, we isolated nine type I genes from Petunia, which belong to the Mgamma subclass, and investigated the divergence of their coding and regulatory regions. The isolated genes could be subdivided into two categories: two genes were highly similar to Arabidopsis Mgamma-type genes, whereas the other seven genes showed less similarity to Arabidopsis genes and originated more recently. Two of the recently duplicated genes were found to contain deleterious mutations in their coding regions, and expression analysis revealed that a third paralog was silenced by mutations in its regulatory region. However, in addition to the three genes that were subjected to nonfunctionalization, we also found evidence for neofunctionalization of one of the Petunia Mgamma-type genes. Our study shows a rapid divergence of recently duplicated Mgamma-type MADS-box genes and suggests that redundancy among type I paralogs may be less common than expected.

    Full Text Available Este artigo apresenta temas sobre a experiência e o pensamento na Ordem dos Frades Menores Capuchinhos, que evidenciam a riqueza da perspectiva cultural da Geografia, sua espacialização, sua presença social e espiritual em diferentes fatos históricos. Visa-se a conhecer e a descrever a Ordem dos Frades Menores Capuchinhos, com ênfase à sua presença no estado do Rio Grande do Sul, Brasil, descrevendo atitudes, valores, entre outros aspectos, vinculados ao sentido e aos símbolos espiritualizados deste clero. Identificou-se o contexto da imigração italiana, no século XIX, e a con- sequente inserção dessa Ordem no Rio Grande do Sul como ponto de partida. A metodologia consistiu em uma análise documental, em textos de comentadores da filosofia franciscana e de entrevistas realizadas com oito frades Capuchinhos que pertencem à Província Sagrado Coração de Jesus. O artigo, pela complexidade do tema, não pode tratar detalhadamente da descrição da Ordem e dos símbolos em sua profundidade espiritual. Apenas destacou-se a abrangência geográfica dessa Ordem no Estado gaúcho e no Brasil e, também, nos países latino-americanos como Haiti e República Dominicana e evidenciou-se a vida religiosa consagrada, pela sua natureza, inserida na Igreja, contribuindo com sua presença e missão para o bem do povo de Deus. Constatou-se que o simbolismo franciscano está presente na atual sociedade, mesmo que esta não perceba, principalmente, difundido através do presépio e do Tau; e que os votos e a saudação de “Paz e Bem” apresentam maiores significados para aqueles que praticam essa filosofia de vida

    Full Text Available Box graphs succinctly and comprehensively characterize singular fibers of elliptic fibrations in codimension two and three, as well as flop transitions connecting these, in terms of representation theoretic data. We develop a framework that provides a systematic map between a box graph and a crepant algebraic resolution of the singular elliptic fibration, thus allowing an explicit construction of the fibers from a singular Weierstrass or Tate model. The key tool is what we call a fiber face diagram, which shows the relevant information of a (partial toric triangulation and allows the inclusion of more general algebraic blowups. We shown that each such diagram defines a sequence of weighted algebraic blowups, thus providing a realization of the fiber defined by the box graph in terms of an explicit resolution. We show this correspondence explicitly for the case of SU(5 by providing a map between box graphs and fiber faces, and thereby a sequence of algebraic resolutions of the Tate model, which realizes each of the box graphs.

  9. Decontamination of TRU glove boxes

    Crawford, J.H.

    1978-03-01

    Two glove boxes that had been used for work with transuranic nuclides (TRU) for about 12 years were decontaminated in a test program to collect data for developing a decontamination facility for large equipment highly contaminated with alpha emitters. A simple chemical technique consisting of a cycle of water flushes and alkaline permanganate and oxalic acid washes was used for both boxes. The test showed that glove boxes and similar equipment that are grossly contaminated with transuranic nuclides can be decontaminated to the current DIE nonretrievable disposal guide of <10 nCi TRU/g with a moderate amount of decontamination solution and manpower. Decontamination of the first box from an estimated 1.3 Ci to about 5 mCi (6 nCi/g) required 1.3 gallons of decontamination solution and 0.03 man-hour of work for each square foot of surface area. The second box was decontaminated from an estimated 3.4 Ci to about 2.8 mCi (4.2 nCi/g) using 0.9 gallon of decontamination solution and 0.02 man-hour for each square foot of surface area. Further reductions in contamination were achieved by repetitive decontamination cycles, but the effectiveness of the technique decreased sharply after the initial cycle

    1988-01-01

    The continued existence of boxing as an accepted sport in civilized society has been long debated. The position of the American Medical Association (AMA) has evolved from promoting increased safety and medical reform to recommending total abolition of both amateur and professional boxing. In response to the AMA opposition to boxing, the boxing community has attempted to increase the safeguards in amateur and professional boxing. The United States of America Amateur Boxing Federation, which is the national regulatory agency for all amateur boxing in the United States, has taken several actions to prevent the occurrence of acute brain injury and is currently conducting epidemiologic studies to assess the long-term neuropsychologic consequences of amateur boxing. In professional boxing, state regulatory agencies such as the New York State Athletic Commission have introduced several medical interventions to prevent and reduce neurologic injury. The lack of a national regulatory agency to govern professional boxing has stimulated the formation of the Association of Boxing Commissions and potential legislation for the federal regulation of professional boxing by a federally chartered organization called the United States Boxing Commission. The AMA's opposition to boxing and the medical and safety reforms implemented by the proponents of boxing are discussed. PMID:3385788

    Full Text Available The purpose of this study was to find out the management skills required by boxing coaches to administrate their clubs. For the purposes of this study a scale was constructed which was answered by 98 boxing coaches. Explanatory factor analysis revealed seven factors: Communication-public relations (5 items, event management (4 items, management techniques (4 items, new technologies (4 items, prevention-safety (2 items, sport (5 items and sports facilities (2 items. The Cronbach of the scale was 0.85. The five competencies that rated by the coaches were: Supervisors of the area of training, maintaining excellent communication with athletes, using new technologies (e-mail, internet, handling disciplinary matters, accidents, complaints and reports on some sporting games and promoted harmony among athletes. We concluded that boxing coaches understand that the competencies required for meeting their obligations, were related to sports, prevention, safety and communications-public relations.

  14. The Boxing Day Tsunami: Could the Disaster have been Anticipated?

    Cummins, P. R.; Burbdige, D.

    2005-05-01

    The occurrence of the 26 December, 2004 Sumatra-Andaman earthquake and the accompanying "Boxing Day" Tsunami, which killed over 280,00, has been described as one of the most lethal natural disasters in human history. Many lives could have been saved had a tsunami warning system, similar to that which exists for the Pacific Ocean, been in operation for the Indian Ocean. The former exists because great subduction zone earthquakes have generated destructive, Pacific-wide tsunami in the Pacific Ocean with some frequency. Prior to 26 December, 2004, all of the world's earthquakes with magnitude > 9 were widely thought to have occurred in the Pacific Ocean, where they caused destructive tsunami. Could the occurrence of similar earthquakes and tsunami in the Indian Ocean been predicted prior to the 2004 Box Day Tragedy? This presentation will argue that the answer is "Yes". Almost without exception (the exception being the 1952 Kamchatka earthquake) the massive subduction zone earthquakes and tsunami of the Pacific Ocean have been associated with the subduction of relatively young ocean lithosphere (Boxing day event, the effects in the Bay of Bengal would not have been as severe. Thus, it seems to this author that the Boxing Day event could and should have been anticipated. This presentation will further consider why it was not, and what steps can be taken to anticipate and mitigate the effects of future events that may occur in the Indian Ocean and elsewhere.

Neurofilament light protein, total tau, glial fibrillary acidic protein, phosphorylated tau, and beta-amyloid protein 1-40 (Abeta([1-40])) and 1-42 (Abeta([1-42])) concentrations in cerebrospinal fluid were measured. Increased levels after a bout compared with after 3 months of rest from boxing were found for 2 markers for neuronal and axonal injury, neurofilament light protein (mean +/- SD, 845 +/- 1140 ng/L vs 208 +/- 108 ng/L; P = .008) and total tau (mean +/- SD, 449 +/- 176 ng/L vs 306 +/- 78 ng/L; P = .006), and for the astroglial injury marker glial fibrillary acidic protein (mean +/- SD, 541 +/- 199 ng/L vs 405 +/- 138 ng/L; P = .003). The increase was significantly higher among boxers who had received many hits (>15) or high-impact hits to the head compared with boxers who reported few hits. In the boxers, concentrations of neurofilament light protein and glial fibrillary acidic protein, but not total tau, were significantly elevated after a bout compared with the nonathletic control subjects. With the exception of neurofilament light protein, there were no significant differences between boxers after 3 months of rest from boxing and the nonathletic control subjects. Amateur boxing is associated with acute neuronal and astroglial injury. If verified in longitudinal studies with extensive follow-up regarding the clinical outcome, analyses of cerebrospinal fluid may provide a scientific basis for

    Monitoring prestressing forces is essential for prestressed concrete box girder bridges. However, the current monitoring methods used for prestressing force were not applicable for a box girder neither because of the sensor’s setup being constrained or shear lag effect not being properly considered. Through combining with the previous analysis model of shear lag effect in the box girder, this paper proposed an indirect monitoring method for on-site determination of prestressing force in a concrete box girder utilizing the distributed long-gauge fiber Bragg grating sensor. The performance of this method was initially verified using numerical simulation for three different distribution forms of prestressing tendons. Then, an experiment involving two concrete box girders was conducted to study the feasibility of this method under different prestressing levels preliminarily. The results of both numerical simulation and lab experiment validated this method’s practicability in a box girder.

    2018-01-01

    Meaning is a central feature in human life, but death can disrupt a sense of meaning. Two experiments tested the hypothesis that meaning in life and meaning in death are distinct types of meaning when mortality is salient and differentially affect death-thought accessibility (DTA). In Experiment 1, imagining a specific scenario in which meaning is preserved beyond death reduced DTA relative to a standard mortality salience prime; moreover, these effects were not due to changes in self-esteem. In Experiment 2, imagining a meaningful life when mortality is salient elicited greater DTA, whereas imagining meaning in death elicited less DTA. Imbuing death with meaning attenuates DTA, whereas meaning in life increases DTA. © 2017 The British Psychological Society.

    2014-02-10

    The F-box protein family is characterized by an F-box motif that has been shown to play an important role in regulating various developmental processes and stress responses. In this study, a novel F-box-containing gene was isolated from leaves of pepper cultivar P70 (Capsicum annuum L.) and designated CaF-box. The full-length cDNA is 2088 bp and contains an open reading frame of 1914 bp encoding a putative polypeptide of 638 amino acids with a mass of 67.8 kDa. CaF-box was expressed predominantly in stems and seeds, and the transcript was markedly upregulated in response to cold stress, abscisic acid (ABA) and salicylic acid (SA) treatment, and downregulated under osmotic and heavy metal stress. CaF-box expression was dramatically affected by salt stress, and was rapidly increased for the first hour, then sharply decreased thereafter. In order to further assess the role of CaF-box in the defense response to abiotic stress, a loss-of-function experiment in pepper plants was performed using a virus-induced gene silencing (VIGS) technique. Measurement of thiobarbituric acid reactive substances (TBARS) and electrolyte leakage revealed stronger lipid peroxidation and cell death in the CaF-box-silenced plants than in control plants, suggesting CaF-box plays an important role in regulating the defense response to abiotic stress resistance in pepper plants.

  4. Non-local boxes and their implementation in Minecraft

    Science.gov (United States)

    Simnacher, Timo Yannick

    PR-boxes are binary devices connecting two remote parties satisfying x AND y = a + b mod 2, where x and y denote the binary inputs and a and b are the respective outcomes without signaling. These devices are named after their inventors Sandu Popescu and Daniel Rohrlich and saturate the Clauser-Horne-Shimony-Holt (CHSH) inequality. This Bell-like inequality bounds the correlation that can exist between two remote, non-signaling, classical systems described by local hidden variable theories. Experiments have now convincingly shown that quantum entanglement cannot be explained by local hidden variable theories. Furthermore, the CHSH inequality provides a method to distinguish quantum systems from super-quantum correlations. The correlation between the outputs of the PR-box goes beyond any quantum entanglement. Though PR-boxes would have impressive consequences, as far as we know they are not physically realizable. However, by introducing PR-boxes to Minecraft as part of the redstone system, which simulates the electrical components for binary computing, we can experience the consequences of super-quantum correlations. For instance, Wim van Dam proved that two parties can use a sufficient number of PR-boxes to compute any Boolean function f(x,y) with only one bit of communication.

  5. Comparison of Geometrical Layouts for a Multi-Box Aerosol Model from a Single-Chamber Dispersion Study

    Alexander C. Ø. Jensen

    2018-04-01

    Full Text Available Models are increasingly used to estimate and pre-emptively calculate the occupational exposure of airborne released particulate matter. Typical two-box models assume instant and fully mixed air volumes, which can potentially cause issues in cases with fast processes, slow air mixing, and/or large volumes. In this study, we present an aerosol dispersion model and validate it by comparing the modelled concentrations with concentrations measured during chamber experiments. We investigated whether a better estimation of concentrations was possible by using different geometrical layouts rather than a typical two-box layout. A one-box, two-box, and two three-box layouts were used. The one box model was found to underestimate the concentrations close to the source, while overestimating the concentrations in the far field. The two-box model layout performed well based on comparisons from the chamber study in systems with a steady source concentration for both slow and fast mixing. The three-box layout was found to better estimate the concentrations and the timing of the peaks for fluctuating concentrations than the one-box or two-box layouts under relatively slow mixing conditions. This finding suggests that industry-relevant scaled volumes should be tested in practice to gain more knowledge about when to use the two-box or the three-box layout schemes for multi-box models.

    Covering both the history of mathematics and of philosophy, Descartes's Mathematical Thought reconstructs the intellectual career of Descartes most comprehensively and originally in a global perspective including the history of early modern China and Japan. Especially, it shows what the concept of "mathesis universalis" meant before and during the period of Descartes and how it influenced the young Descartes. In fact, it was the most fundamental mathematical discipline during the seventeenth century, and for Descartes a key notion which may have led to his novel mathematics of algebraic analysis.

    This paper develops a novel approach for multitarget tracking, called box-particle probability hypothesis density filter (box-PHD filter). The approach is able to track multiple targets and estimates the unknown number of targets. Furthermore, it is capable of dealing with three sources of uncertainty: stochastic, set-theoretic, and data association uncertainty. The box-PHD filter reduces the number of particles significantly, which improves the runtime considerably. The small number of box-p...

  9. Project governance: "Schools of thought"

    Directory of Open Access Journals (Sweden)

    Michiel Christiaan Bekker

    2014-02-01

    Full Text Available The terminology, definition and context of project governance have become a focal subject for research and discussions in project management literature. This article reviews literature on the subject of project governance and categorise the arguments into three schools of thought namely the single-firm school, multi-firm school and large capital school. The single-firm school is concerned with governance principles related to internal organisational projects and practice these principles at a technical level. The multi-firm school address the governance principles concerned with two of more organisations participating on a contractual basis on the same project and focus their governance efforts at the technical and strategic level. The large capital school consider projects as temporary organisations, forming their own entity and establishing governance principles at an institutional level. From these schools of thought it can be concluded that the definition of project governance is dependent on the type of project and hierarchical positioning in the organisation. It is also evident that further research is required to incorporate other governance variables and mechanisms such as transaction theory, social networks and agency theory. The development of project governance frameworks should also consider the complexity of projects spanning across international companies, across country borders and incorporating different value systems, legal systems, corporate governance guidelines, religions and business practices.

  10. Aging and repeated thought suppression success.

    Directory of Open Access Journals (Sweden)

    Ann E Lambert

    Full Text Available Intrusive thoughts and attempts to suppress them are common, but while suppression may be effective in the short-term, it can increase thought recurrence in the long-term. Because intentional suppression involves controlled processing, and many aspects of controlled processing decline with age, age differences in thought suppression outcomes may emerge, especially over repeated thought suppression attempts as cognitive resources are expended. Using multilevel modeling, we examined age differences in reactions to thought suppression attempts across four thought suppression sequences in 40 older and 42 younger adults. As expected, age differences were more prevalent during suppression than during free monitoring periods, with younger adults indicating longer, more frequent thought recurrences and greater suppression difficulty. Further, younger adults' thought suppression outcomes changed over time, while trajectories for older adults' were relatively stable. Results are discussed in terms of older adults' reduced thought recurrence, which was potentially afforded by age-related changes in reactive control and distractibility.

    Glove box clean-up experiments were conducted in a nitrogen glove box using palladium deposited on zeolite (Pd/z) and a SAES St 198 trademark getter as tritium stripping materials. Protium/deuterium samples spiked with tritium were released into a 620 liter glove box to simulate tritium releases in a 10,500 liter glove box. The Pd/z and the SAES St 198 trademark stripper beds produced a reduction in tritium activity of approximately two to three orders of magnitude and glove box clean-up was limited by a persistent background tritium activity level. Attempts to significantly reduce the glove box activity to lower levels without purging were unsuccessful

    This invention relates to a water box for connecting an assembly composed of a vertical steam generator and a vertical pump to the vessel of the nuclear reactor, the assembly forming the primary cooling system of a pressurised water reactor. This invention makes it easy to dismantle the pump on the water box without significant loss of water in the primary cooling system of the reactor and particularly without it being necessary to drain the water contained in the steam generator beforehand. It makes it possible to shorten the time required for dismantling the primary pump in order to service or repair it and makes dismantling safer in that the dismantling does not involve draining the steam generator and therefore the critical storage of a large amount of cooling water that has been in contact with the fuel assemblies of the nuclear reactor core [fr

  17. Choice as an engine of analytic thought.

    2017-09-01

    Choice is a behavioral act that has a variety of well-documented motivational consequences-it fosters independence by allowing people to simultaneously express themselves and influence the environment. Given the link between independence and analytic thinking, the current research tested whether choice also leads people to think in a more analytic rather than holistic manner. Four experiments demonstrate that making choices, recalling choices, and viewing others make choices leads people to think more analytically, as indicated by their attitudes, perceptual judgments, categorization, and patterns of attention allocation. People who made choices scored higher on a subjective self-report measure of analytic cognition compared to whose did not make a choice (pilot study). Using an objective task-based measure, people who recalled choices rather than actions were less influenced by changes in the background when making judgments about focal objects (Experiment 1). People who thought of others' behaviors as choices rather than actions were more likely to group objects based on categories rather than relationships (Experiment 2). People who recalled choices rather than actions subsequently allocated more visual attention to focal objects in a scene (Experiment 3). Together, these experiments demonstrate that choice has important yet previously unexamined consequences for basic psychological processes such as attention and cognition.

    Ottoboni, Giovanni; Russo, Gabriele; Tessari, Alessia

    2015-01-01

    When two athletes meet inside the ropes of the boxing ring to fight, their cognitive systems have to respond as quickly as possible to a manifold of stimuli to assure victory. In the present work, we studied the pre-attentive mechanisms, which form the basis of an athlete's ability in reacting to an opponent's punches. Expert boxers, beginner boxers and people with no experience of boxing performed a Simon-like task where they judged the colour of the boxing gloves worn by athletes in attack postures by pressing two lateralised keys. Although participants were not instructed to pay attention to the direction of the punches, beginner boxers' responses resembled a defence-related pattern, expert boxers' resembled counterattacks, whereas non-athletes' responses were not influenced by the unrelated task information. Results are discussed in the light of an expertise-related action simulation account.

    The model-independent 'box' parameterization of neutrino oscillations is examined. The invariant boxes are the classical amplitudes of the individual oscillating terms. Being observables, the boxes are independent of the choice of parameterization of the mixing matrix. Emphasis is placed on the relations among the box parameters due to mixing-matrix unitarity, and on the reduction of the number of boxes to the minimum basis set. Using the box algebra, we show that CP-violation may be inferred from measurements of neutrino flavor mixing even when the oscillatory factors have averaged. General analyses of neutrino oscillations among n≥3 flavors can readily determine the boxes, which can then be manipulated to yield magnitudes of mixing matrix elements

  5. Psychopathology and Thought Suppression: A Quantitative Review

    Magee, Joshua C.; Harden, K. Paige; Teachman, Bethany A.

    2012-01-01

    Recent theories of psychopathology have suggested that thought suppression intensifies the persistence of intrusive thoughts, and proposed that difficulty with thought suppression may differ between groups with and without psychopathology. The current meta-analytic review evaluates empirical evidence for difficulty with thought suppression as a function of the presence and specific type of psychopathology. Based on theoretical proposals from the psychopathology literature, diagnosed and analogue samples were expected to show greater recurrence of intrusive thoughts during thought suppression attempts than non-clinical samples. However, results showed no overall differences in the recurrence of thoughts due to thought suppression between groups with and without psychopathology. There was, nevertheless, variation in the recurrence of thoughts across different forms of psychopathology, including relatively less recurrence during thought suppression for samples with symptoms of Obsessive-Compulsive Disorder, compared to non-clinical samples. However, these differences were typically small and provided only mixed support for existing theories. Implications for cognitive theories of intrusive thoughts are discussed, including proposed mechanisms underlying thought suppression. PMID:22388007

    In 2012, 22 days of beam time will be allocated for LHC MDs. In this paper, after recalling the 2011 LHC MD experience, the MD rrequests for 2012 are reviewed. Three primary MD themes for 2012 can be identified: 1)pushing performance in 2012, 2)preparing for 2014/15, and 3)towards maximum luminosity. Example topics include emittance growth in collision or enhanced satellites for theme 1), 25 ns operation for 2), and ATS optics for 3). Structures lists of MD requests and topics for each theme as well as some initial thoughts on the MD priorities are presented. For certain topics, "start-of-fill MDs" are proposed in order to most efficiently use of the available beam time.

  7. A new set of ESTs from chickpea (Cicer arietinum L. embryo reveals two novel F-box genes, CarF-box_PP2 and CarF-box_LysM, with potential roles in seed development.

    Directory of Open Access Journals (Sweden)

    Shefali Gupta

    Full Text Available Considering the economic importance of chickpea (C. arietinum L. seeds, it is important to understand the mechanisms underlying seed development for which a cDNA library was constructed from 6 day old chickpea embryos. A total of 8,186 ESTs were obtained from which 4,048 high quality ESTs were assembled into 1,480 unigenes that majorly encoded genes involved in various metabolic and regulatory pathways. Of these, 95 ESTs were found to be involved in ubiquitination related protein degradation pathways and 12 ESTs coded specifically for putative F-box proteins. Differential transcript accumulation of these putative F-box genes was observed in chickpea tissues as evidenced by quantitative real-time PCR. Further, to explore the role of F-box proteins in chickpea seed development, two F-box genes were selected for molecular characterization. These were named as CarF-box_PP2 and CarF-box_LysM depending on their C-terminal domains, PP2 and LysM, respectively. Their highly conserved structures led us to predict their target substrates. Subcellular localization experiment revealed that CarF-box_PP2 was localized in the cytoplasm and CarF-box_LysM was localized in the nucleus. We demonstrated their physical interactions with SKP1 protein, which validated that they function as F-box proteins in the formation of SCF complexes. Sequence analysis of their promoter regions revealed certain seed specific cis-acting elements that may be regulating their preferential transcript accumulation in the seed. Overall, the study helped in expanding the EST database of chickpea, which was further used to identify two novel F-box genes having a potential role in seed development.

    Considering the economic importance of chickpea (C. arietinum L.) seeds, it is important to understand the mechanisms underlying seed development for which a cDNA library was constructed from 6 day old chickpea embryos. A total of 8,186 ESTs were obtained from which 4,048 high quality ESTs were assembled into 1,480 unigenes that majorly encoded genes involved in various metabolic and regulatory pathways. Of these, 95 ESTs were found to be involved in ubiquitination related protein degradation pathways and 12 ESTs coded specifically for putative F-box proteins. Differential transcript accumulation of these putative F-box genes was observed in chickpea tissues as evidenced by quantitative real-time PCR. Further, to explore the role of F-box proteins in chickpea seed development, two F-box genes were selected for molecular characterization. These were named as CarF-box_PP2 and CarF-box_LysM depending on their C-terminal domains, PP2 and LysM, respectively. Their highly conserved structures led us to predict their target substrates. Subcellular localization experiment revealed that CarF-box_PP2 was localized in the cytoplasm and CarF-box_LysM was localized in the nucleus. We demonstrated their physical interactions with SKP1 protein, which validated that they function as F-box proteins in the formation of SCF complexes. Sequence analysis of their promoter regions revealed certain seed specific cis-acting elements that may be regulating their preferential transcript accumulation in the seed. Overall, the study helped in expanding the EST database of chickpea, which was further used to identify two novel F-box genes having a potential role in seed development.

  9. Functions of DEAD-box proteins in bacteria: current knowledge and pending questions.

    DEAD-box proteins are RNA-dependent ATPases that are widespread in all three kingdoms of life. They are thought to rearrange the structures of RNA or ribonucleoprotein complexes but their exact mechanism of action is rarely known. Whereas in yeast most DEAD-box proteins are essential, no example of an essential bacterial DEAD-box protein has been reported so far; at most, their absence results in cold-sensitive growth. Moreover, whereas yeast DEAD-box proteins are implicated in virtually all reactions involving RNA, in E. coli (the bacterium where DEAD-box proteins have been mostly studied) their role is limited to ribosome biogenesis, mRNA degradation, and possibly translation initiation. Plausible reasons for these differences are discussed here. In spite of their dispensability, E. coli DEAD-box proteins are valuable models for the mechanism of action of DEAD-box proteins in general because the reactions in which they participate can be reproduced in vitro. Here we review our present understanding of this mechanism of action. Using selected examples for which information is available: (i) we describe how, by interacting directly with a particular RNA motif or by binding to proteins that themselves recognize such a motif, DEAD-box proteins are brought to their specific RNA substrate(s); (ii) we discuss the nature of the structural transitions that DEAD-box proteins induce on their substrates; and (iii) we analyze the reasons why these proteins are mostly important at low temperatures.

  10. Second-to-Last Thoughts

    Science.gov (United States)

    Trimble, Virginia L.

    2016-06-01

    You can’t really prepare an abstract of a concluding-remarks talk, but having spent 19 years, 8 months as a full time student (Sept. 1948, Toluca Lake Grammar School kindergarten to April 1968 Caltech Ph.D.), most of the ensuing 48 years as a teacher, and about 51 years as some sort of astronomer, I find myself woefully ignorant of astronomy education and therefore well prepared to bring a fresh and vacant mind to the ideas presented by our colleagues here. Several thoughts, however, intrude. First, as Cecilia Payne Gaposchkin said, “a woman should do astronomy only if nothing else will satisfy her, for nothing else is what she will get.” Make that “person” and “science” and it still carries much truth. Second, it is better to be a professional astronomer and an amateur alto than the converse. And third, it is better to be a professional dentist and an amateur astronomer than the converse. This, I think, leaves room for all of us to work in areas that we find attractive and that we turn out to be reasonably good at. The latter is at least as important as the former. There is a great deal of pleasure to be found as a second-rate singer or artist, but not, I hope, as a lousy astronomer or teacher.

  11. Thoughts on the nude body

    Directory of Open Access Journals (Sweden)

    Paolo Fabbri

    2016-07-01

    Full Text Available The image of nude appears to have ‘moved’, both because of the shift in our gaze and its point of reference. That is, unless this ‘negative emphasis’ is seen only as the uncri­ti­cal acceptance of that ‘polarizing question’ that declared the end of Clas­sical art and the decisive advent of modernity or as the effect of an hermeneutic excess ‒ of a philosophical definition of the nude impli­cit in our figurative culture – is it now the moment to go beyond the observation of the canonic nude and to develop new approaches to nudity? Despite its obviousness, the nude, too, is difficult to define. Where does the garment begin and the gown end? The skin and the flesh? How are we to describe the for­ces, movements and gestures of the body and its involucres? I will argue that the nude should be neither a pictorial genre nor a philosophical concept, but a «thought of the body» (De Chirico. It is an aesthetic figure with the power of affection and perception, but also a conceptual figure. It is not a ‘critical operator’ ‒ a cognitive ‘walk-on’ or extra ‒ but an actor with the power of speech, capable of forming and transforming new relationships with observers.

  12. Voronoi Diagrams Without Bounding Boxes

    Sang, E. T. K.

    2015-10-01

    We present a technique for presenting geographic data in Voronoi diagrams without having to specify a bounding box. The method restricts Voronoi cells to points within a user-defined distance of the data points. The mathematical foundation of the approach is presented as well. The cell clipping method is particularly useful for presenting geographic data that is spread in an irregular way over a map, as for example the Dutch dialect data displayed in Figure 2. The automatic generation of reasonable cell boundaries also makes redundant a frequently used solution to this problem that requires data owners to specify region boundaries, as in Goebl (2010) and Nerbonne et al (2011).

  13. Thinking Outside the Box: Orbitofrontal Cortex, Imagination, and How We Can Treat Addiction.

    2016-12-01

    Addiction involves an inability to control drug-seeking behavior. While this may be thought of as secondary to an overwhelming desire for drugs, it could equally well reflect a failure of the brain mechanisms that allow addicts to learn about and mentally simulate non-drug consequences. Importantly, this process of mental simulation draws upon, but is not normally bound by, our past experiences. Rather we have the ability to think outside the box of our past, integrating knowledge gained from a variety of similar and not-so-similar life experiences to derive estimates or imagine what might happen next. These estimates influence our current behavior directly and also affect future behavior by serving as the background against which outcomes are evaluated to support learning. Here we will review evidence, from our own work using a Pavlovian over-expectation task as well as from other sources, that the orbitofrontal cortex is a critical node in the neural circuit that generates these estimates. Further we will offer the specific hypothesis that degradation of this function secondary to drug-induced changes is a critical and likely addressable part of addiction.

    2013-01-01

    This paper presents a novel method for solving nonlinear filtering problems. This approach is particularly appealing in practical situations involving imprecise stochastic measurements, thus resulting in very broad posterior densities. It relies on the concept of a box particle, which occupies a small and controllable rectangular region having a non-zero volume in the state space. Key advantages of the box particle filter (Box-PF) against the standard particle filter (PF) are in its reduced c...

    The exact two-particle energy eigenstates in an asymmetric rectangular box with periodic boundary conditions in all three directions are studied. Their relation with the elastic scattering phases of the two particles in the continuum are obtained. These results can be viewed as a generalization of the corresponding formulae in a cubic box obtained by L\\"uscher before. In particular, the s-wave scattering length is related to the energy shift in the finite box. Possible applications of these f...

  16. A Penny for Your Thoughts: Dimensions of Thought Content and Relationships with Individual Differences in Emotional Well-Being

    Jessica R Andrews-Hanna

    2013-11-01

    Full Text Available A core aspect of human cognition involves overcoming the constraints of the present environment by mentally simulating another time, place, or perspective. Although these self-generated processes confer many benefits, they can come at an important cost, and this cost is greater for some individuals than for others. Here we explore the possibility that the costs and benefits of self-generated thought depend, in part, upon its phenomenological content. To test these hypotheses, we first developed a novel thought sampling paradigm and explored normative ratings of multiple thought content variables (i.e. valence, specificity, self-relevance, etc. across a large sample of young adults. Next, we examined multi-level relationships among these content variables, and used a hierarchical clustering approach to partition self-generated thought into multiple dimensions. Finally, we investigated whether these content dimensions predicted individual differences in the costs and benefits of the experience, assessed with questionnaires measuring emotional health and wellbeing. Individuals who characterized their thoughts as more negative and more personally-significant exhibited scored higher on constructs associated with Depression and Trait Negative Affect, whereas those who characterized their thoughts as less specific scored higher on constructs linked to Rumination. In contrast, individuals who characterized their thoughts as more positive, less personally-significant, and more specific scored higher on constructs linked to improved wellbeing (Mindfulness. Collectively, these findings suggest that the content of people’s inner thoughts can 1 be productively examined, 2 be distilled into several major dimensions, and 3 account for a large portion of variability in their functional outcomes.

  17. Dimension measuring method for channel box

    International Nuclear Information System (INIS)

    Jo, Hiroto.

    1995-01-01

    The device of the present invention concerns detection of a channel box for spent fuel assemblies of a BWR type reactor, which measures a cross sectional shape and dimension of the channel box to check deformation amount such as expansion. That is, a customary fuel exchanger and a dimension measuring device are used. The lower end of the channel box is measured by a distance sensor of the dimension measuring device when it is aligned with a position of the distance sensor. The channel box is lowered at the same time while detecting axial position data of the fuel exchanger. The position of the channel box in an axial direction is detected based on axial position data of the fuel exchanger. The lower end of the channel box can accurately be recognized by the detection of both of them. Subsequent deformation measurement for the channel box at accurate axial positions is enabled. In addition, since the axial position data of the fuel exchanger per se are detected, an axial profile of the channel box can be measured even if a lifting speed of the channel box is varied on every region.

  18. VO₂ requirements of boxing exercises.

    Arseneau, Eric; Mekary, Saïd; Léger, Luc A

    2011-02-01

    The purpose of this study was to quantify the physiological requirements of various boxing exercises such as sparring, pad work, and punching bag. Because it was not possible to measure the oxygen uptake (VO₂) of "true" sparring with a collecting gas valve in the face, we developed and validated a method to measure VO₂ of "true" sparring based on "postexercise" measurements. Nine experienced male amateur boxers (Mean ± SD: age = 22.0 ± 3.5 years, height = 176.0 ± 8.0 cm, weight = 71.4 ± 10.9 kg, number of fights = 13.0 ± 9.5) of regional and provincial level volunteered to participate in 3 testing sessions: (a) maximal treadmill test in the LAB, (b) standardized boxing training in the GYM, and (c) standardized boxing exercises in the LAB. Measures of VO₂, heart rate (HR), blood lactate concentration [LA], rated perceived exertion level, and punching frequencies were collected. VO₂ values of 43.4 ± 5.9, 41.1 ± 5.1, 24.7 ± 6.1, 30.4 ± 5.8, and 38.3 ± 6.5 ml·kg⁻¹·min⁻¹ were obtained, which represent 69.7 ± 8.0, 66.1 ± 8.0, 39.8 ± 10.4, 48.8 ± 8.5, and 61.7 ± 10.3%VO₂peak for sparring, pad work, and punching bag at 60, 120, and 180 b·min⁻¹, respectively. Except for lower VO₂ values for punching the bag at 60 and 120 b·min⁻¹ (p < 0.05), there was no VO₂ difference between exercises. Similar pattern was obtained for %HRmax with respective values of 85.5 ± 5.9, 83.6 ± 6.3, 67.5 ± 3.5, 74.8 ± 5.9, and 83.0 ± 6.0. Finally, sparring %HRmax and [LA] were slightly higher in the GYM (91.7 ± 4.3 and 9.4 ± 2.2 mmol·L⁻¹) vs. LAB (85.5 ± 5.9 and 6.1 ± 2.3 mmol·L⁻¹). Thus, in this study simulated LAB sparring and pad work required similar VO₂ (43-41 ml·kg⁻¹·min⁻¹, respectively), which corresponds to ~70%VO₂peak. These results underline the importance of a minimum of aerobic fitness for boxers and draw some guidelines for the intensity of training.

  20. On the origins of endogenous thoughts.

    Tillas, Alexandros

    2017-05-01

    Endogenous thoughts are thoughts that we activate in a top-down manner or in the absence of the appropriate stimuli. We use endogenous thoughts to plan or recall past events. In this sense, endogenous thinking is one of the hallmarks of our cognitive lives. In this paper, I investigate how it is that we come to possess endogenous control over our thoughts. Starting from the close relation between language and thinking, I look into speech production-a process motorically controlled by the inferior frontal gyrus (IFG). Interestingly, IFG is also closely related to silent talking, as well as volition. The connection between IFG and volition is important given that endogenous thoughts are or at least greatly resemble voluntary actions. Against this background, I argue that IFG is key to understanding the origins of conscious endogenous thoughts. Furthermore, I look into goal-directed thinking and show that IFG plays a key role also in unconscious endogenous thinking.

    2012-01-01

    Full Text Available In cognitive science, the discussion about the relations between language and thought is very heterogeneous. It involves developments on linguistics, philosophy, psychology, etc. Carruthers and Boucher (1998 identify different criteria that would organize the diversity of positions about language and thought assumed in linguistics, philosophy and psychology. One of them is the constitution thesis (CT, which establishes that language is constitutively involved in thought. In this paper I would like to show some problems of CT in order to understand the relation between language and thought in cognitive science.

    This paper recommended the structure of the isolated phase busbar outlet box installed in Qinshan II. The study on partial overheat of the outlet box shows that the ultimate causes are the loss of concentrated eddy current and short of cooling. So the improvement principles of 'distributing eddy current, cutting off inductive circle current and strengthening of ventilation' were determined. A new structure test outlet box was designed and manufactured, and the temperature rising experiment was carried out. Some alterations were made in the new structure outlet box, e.g. isolating materials were added between side plates of the upper outlet box, and also between the upper and lower outlet box. Two cooling blowers were added to the upper outlet box. After putting into operation, the hot-spot temperature of the new outlet box was greatly lowered down. Thus the operation environment was improved, and the operation safety ensured. It can be useful references for analyzing and dealing with similar problems. (authors)

  6. The magic of Rudaki's thought and literary language

    2009-06-01

    Full Text Available This article, at first, discuses the fact that language is the most important means of human being to reach the fact and beauty. Language is a means of logical thinking rather than a way of communication. However, literary language in Rudaki's poetry has the best capacity to identify and reveal mental concepts through using aesthetics. The main question of this article is how Rudaki connected language to thought and what is his artistic creation? For this reason the researcher, after presenting and considering evidences, proves that Rudaki has used all characteristics of language and principals of creative language to connect literary language and thought together. The most prominent elements of Rudaki's thought and literary language are: using the most proper words in collocation, distinguishing the relationship of cause and effect and existence through literary language, asserting artistic fact, using imagination and principles of association of meanings, and entering poetical experience in language dominion (domain.

    Science.gov (United States)

    Walker, Justin; Boldyrev, Stanislav

    2017-10-01

    Magnetic dynamo action caused by the magnetorotational instability is studied in the shearing-box approximation with no imposed net magnetic flux. Consistent with recent studies, the dynamo action is found to be sensitive to the aspect ratio of the box: it is much easier to obtain in tall boxes (stretched in the direction normal to the disk plane) than in long boxes (stretched in the radial direction). Our direct numerical simulations indicate that the dynamo is possible in both cases, given a large enough magnetic Reynolds number. To explain the relatively larger effort required to obtain the dynamo action in a long box, we propose that the turbulent eddies caused by the instability most efficiently fold and mix the magnetic field lines in the radial direction. As a result, in the long box the scale of the generated strong azimuthal (stream-wise directed) magnetic field is always comparable to the scale of the turbulent eddies. In contrast, in the tall box the azimuthal magnetic flux spreads in the vertical direction over a distance exceeding the scale of the turbulent eddies. As a result, different vertical sections of the tall box are permeated by large-scale nonzero azimuthal magnetic fluxes, facilitating the instability.

    This paper proposes the small portable type power source `WISH BOX` (wind and solar hybrid) composed of a small wind power generator and solar cell panels. Since solar radiation and wind power are complementary to each other in seasons, day and night, and fine and cloudy weather, WISH BOX is useful for standalone power source in non-power areas of developing countries, life spot in disasters, and outdoor leisure. The most small light-weight high-performance AIR303 produced by Southwest Windpower Co., USA is used as wind power generator, and two 50W solar cell panels HSC-5010-S produced by Daido Hokusan Co. is used. Sealed lead storage batteries (12V, 20Ah each) are also connected to cope with load fluctuation. In comparison with conventional portable gasoline engine generators, this environment-friendly generator is featured by fuel-free, no emission of gases, no noises and no fire occurrence, and can also supply stable power with small batteries even in the nighttime and cloudy weather by combining wind power. The generator of 400,000 yen is now in field experiment. 2 refs., 5 figs.

    Full Text Available Mixed culture is more suitable to adapt more flexible fermentation process and produce different product simultaneously. In this study a mixed Bacillus culture was investigated for their ability to produce the bioplastic "Polyhydroxybutyrate" and both of the mesophilic and the thermophilic proteases in one flask. Box-Behnken experimental design was used. The produced amount of PHB has been increased significantly. Meanwhile there is a competition between PHB and proteases. The maximum produced amount of PHB using Box-Behnken design was 2.82 g/l/48 h with protease activity equal to 41.9 Units/ml/48 h for thermophilic proteases and 99.65 Units/ml/48 h for mesophilic proteases. Excel solver was used for extra-optimization for the optimum conditions obtained from Box-Behnken experiments and its model. The maximum PHB obtained after using Excel solver was 2.88 g/l/48 h. The maximum mesophilic and thermophilic activities obtained at the same PHB production conditions were 175.68 and 243.38 Units/ml respectively.

    Human performance in orbit is currently limited by several factors beyond the intrinsic awkwardness of motor control in weightlessness. Cognitive functioning can be affected by such factors as cumulative sleep loss, stress and the psychological effects of long-duration small-group isolation. When an astronaut operates a scientific experiment, the performance decrement associated with such factors can lead to lost or poor quality data and even the total loss of a scientific objective, at great cost to the sponsors and to the dismay of the Principal Investigator. In long-duration flights, as anticipated on the International Space Station and on any planetary exploration, the experimental model is further complicated by long delays between training and experiment, and the large number of experiments each crew member must perform. Although no documented studies have been published on the subject, astronauts report that an unusually large number of simple errors are made in space. Whether a result of the effects of microgravity, accumulated fatigue, stress or other factors, this pattern of increased error supports the need for a computerized decision-making aid for astronauts performing experiments. Artificial intelligence and expert systems might serve as powerful tools for assisting experiments in space. Those conducting space experiments typically need assistance exactly when the planned checklist does not apply. Expert systems, which use bits of human knowledge and human methods to respond appropriately to unusual situations, have a flexibility that is highly desirable in circumstances where an invariably predictable course of action/response does not exist. Frequently the human expert on the ground is unavailable, lacking the latest information, or not consulted by the astronaut conducting the experiment. In response to these issues, we have developed "Principal Investigator-in-a-Box," or [PI], to capture the reasoning process of the real expert, the Principal

    In cooperation with the New York State Athletic Commission, 74 boxers applying for a new or yearly renewal license were sequentially referred over a 2-year period for a complete dilated ocular examination at the Sports Vision Institute of the Manhattan Eye, Ear and Throat Hospital. At least one ocular injury was found in 66% of boxers. Vision-threatening injuries, defined as significant damage to the angle, lens, macula, or peripheral retina occurred in 58% of boxers. Nineteen percent of boxers had angle abnormalities. Nineteen percent of boxers had pathologic cataracts, over 70% of these were posterior subcapsular. Six boxers had macular lesions. A total of 24% of boxers had retinal tears. Standardized photographs were used to distinguish pathologic cataracts from congenital opacities and pathologic retinal tears from atrophic holes. Attempts were made to identify risk factors in boxing that might be predictive for ocular injury. Variables included age, weight division, left- or right-handedness, total number of losses, and total number of bouts. Significant correlations were found between the total number of bouts and the total number of losses, and the presence of retinal tears. College varsity athletes were selected as controls. Significant differences were found between boxers and controls for the total number of injuries, total vision-threatening injuries, and the number of retinal tears. A series of recommendations are proposed to aide in the early detection and prevention of serious ocular injuries.

    Gene expression is highly controlled and regulated in living cells. One of the first steps in gene transcription is recognition of the promoter site by the TATA box Binding Protein (TBP). TBP recruits other transcriptions factors and eventually the RNA polymerase II to transcribe the DNA in mRNA. We developed a single pair Förster Resonance Energy Transfer (spFRET) assay to investigate the mechanism of gene regulation. Here, we apply this assay to investigate the initial binding process of TBP to the adenovirus major late (AdML) promoter site. From the spFRET measurements, we were able to identify two conformations of the TBP-DNA complex that correspond to TBP bound in the correct and the opposite orientation. Increased incubation times or the presence of the transcription factor TFIIA improved the alignment of TBP on the promoter site. Binding of TBP to the TATA box shows a rich dynamics with abrupt transitions between multiple FRET states. A frame-wise histogram analysis revealed the presence of at least six discrete states, showing that TBP binding is more complicated than previously thought. Hence, the spFRET assay is very sensitive to the conformation of the TBP-DNA complex and is very promising tool for investigating the pathway of TBP binding in detail.

    For the examination of spent fuels and high radioactive specimens using a specially equipped scanning electron microscope, a shielded glove box was designed and constructed at PIE facility of KAERI. This glove box consisted of shielding walls, containment box, lead glasses, manipulators, gloves, ventilation systems, doors, hot-cell specimen cask adapter, etc. It was emphasized that both the easy operation and radiation safety are important factors in the shielded glove box were installed also considered as a important factor to build the basic concept of the assembling. Two sliding doors and one hinge-type door were installed for the easy installation, operation and maintenance of scanning electron microscope. Containment box which confines the radioactive material into the box consisted of reinforced transparent glasses, aluminum frames and stainless steel plate liner. Therefore everything beyond the containment box can be seen through the lead glass which installed at the front shielding wall. All shielding walls and doors were introduced separately into the room and assembled by bolting. (author). 3 refs., 5 tabs., 18 figs

For the analysis of the symbiologies, we start from the criterion that when they are used politically in the environmental thought it is not done necessarily with an intention of strategic use I specify, but that its use can be by the implicit valuations that have these symbiologies in the world of the daily life, where the systems of environmental thought also interact of messianic type

    Previous research involving the probabilistic reasoning 'beads task' has consistently demonstrated a jumping-to-conclusions (JTC) bias, where individuals with delusions make decisions based on limited evidence. However, recent studies have suggested that miscomprehension may be confounding the beads task. The current study aimed to test the conventional beads task against a conceptually simpler probabilistic reasoning "box task" METHODS: One hundred non-clinical participants completed both the beads task and the box task, and the Peters et al. Delusions Inventory (PDI) to assess for delusion-proneness. The number of 'draws to decision' was assessed for both tasks. Additionally, the total amount of on-screen evidence was manipulated for the box task, and two new box task measures were assessed (i.e., 'proportion of evidence requested' and 'deviation from optimal solution'). Despite being conceptually similar, the two tasks did not correlate, and participants requested significantly less information on the beads task relative to the box task. High-delusion-prone participants did not demonstrate hastier decisions on either task; in fact, for box task, this group was observed to be significantly more conservative than low-delusion-prone group. Neither task was incentivized; results need replication with a clinical sample. Participants, and particularly those identified as high-delusion-prone, displayed a more conservative style of responding on the novel box task, relative to the beads task. The two tasks, whilst conceptually similar, appear to be tapping different cognitive processes. The implications of these results are discussed in relation to the JTC bias and the theoretical mechanisms thought to underlie it. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The exact two-particle energy eigenstates in an asymmetric rectangular box with periodic boundary conditions in all three directions are studied. Their relation with the elastic scattering phases of the two particles in the continuum are obtained. These results can be viewed as a generalization of the corresponding formulae in a cubic box obtained by Luescher before. In particular, the s-wave scattering length is related to the energy shift in the finite box. Possible applications of these formulae are also discussed

    Heo Joon is one of the best-known physicians of the Chosun Dynasty, the last imperial dynasty (1392~1910) of Korea. He had served King Seonjo () during his practice, and has produced many publications on medicine. Then, how did he actually treat the patients? So far, other than the case when he treated Gwanghaegun's smallpox, it is not clearly known how and when he attended and treated the ill. In his most famous book, the Treasured Mirror of Eastern Medicine, he details the physiopathological mechanisms, diagnoses, treatments or prescriptions, and treatment cases, however, it is not clear if they're from his own clinical experiences. Nevertheless, based on the written method, the original information is reconstituted according to its respective editors of the TMEM, a particular case being included may be considered as an agreement and acceptance of an actual treatment executed. This research analyzes what type of medicinal theory that the main writer Heo Joon employed in his real treatments, as well as how he diagnosed and treated diseases. After analyzing the complete series of the TMEM, we found a total of 301 clinical cases. Here, one may wonder, why does the Section of Inner and External Bodily Elements, that deal with diseases and the structure of the body, have far outnumber cases than the Section of Miscellaneous Disorders? Why does the TMEM introduce the various types of disease experiences and treatment cases, medical cases, simple treatments, nurturing life, materia medica, and also include supernatural phenomena? Why does the TMEM include the experiences and cases from the book published in the Song, Jin, Yuan dynasty of China, moreover in the Ming Dynasty of its time. These questions can be answered to the extent that Heo Joon and the others who participated in completing the book sought to justify the new clinical medicine practices, and because it had to be acceptable to the Confucius beliefs which dominated the society, and also because the book

    The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants' endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. Together these data suggest that political conservatism may be a process consequence of low-effort thought; when effortful, deliberate thought is disengaged, endorsement of conservative ideology increases.

    2012-08-01

    Engineering robust adhesion of the junction-box (j-box) is a hurdle typically encountered by photovoltaic (PV) module manufacturers during product development. There are historical incidences of adverse effects (e.g., fires) caused when the j-box/adhesive/module system has failed in the field. The addition of a weight to the j-box during the 'damp heat' IEC qualification test is proposed to verify the basic robustness of its adhesion system. The details of the proposed test will be described, in addition to the preliminary results obtained using representative materials and components. The described discovery experiments examine moisture-cured silicone, foam tape, and hot-melt adhesives used in conjunction with PET or glass module 'substrates.' To be able to interpret the results, a set of material-level characterizations was performed, including thermogravimetric analysis, differential scanning calorimetry, and dynamic mechanical analysis. PV j-boxes were adhered to a substrate, loaded with a prescribed weight, and then placed inside an environmental chamber (at 85C, 85% relative humidity). Some systems did not remain attached through the discovery experiments. Observed failure modes include delamination (at the j-box/adhesive or adhesive/substrate interface) and phase change/creep. The results are discussed in the context of the application requirements, in addition to the plan for the formal experiment supporting the proposed modification to the qualification test.

    2007-01-01

    At the Institute for Reference Materials and Measurements (European commission, Joint Research Centre, IRMM) a dismantling campaign of obsolete installations and glove boxes has been carried out in 2005. There were various reasons for their removal. Some large installations did not meet modern safety standards, other installations were worn out and expected to cause a radioactive contamination risk in the future. The main goal was to create as less waste as possible by extensive contamination checks and by decontamination if necessary. For the glove boxes, decontamination was not possible. A controlled area was set up around the installation to be dismantled in order to prevent spreading of contamination from dust and dirt. This was only possible for the 'minor' contaminated installations. The dismantling campaign of the glove boxes was carried out by using tents of two types depending the contamination inside the glove boxes. The most common glove boxes were dismantled in a tent constructed with hard surfaced polycarbonate plates (ventilated cell). For glove boxes with higher contamination, the same principle was used but with a second 'glove box tent' inside (ventilated glove tent). The purpose of this project was to learn from the experience of this campaign which gave the ability to make estimates of future radioactive waste or classic waste that could be expected from dismantled installations.

  1. Alpha contamination assessment for D ampersand D activities: Monitoring inside glove boxes and vessels

    Rawool-Sullivan, M.W.; Bolton, R.D.; Conaway, J.G.; MacArthur, D.W.

    1996-02-01

    We have developed a new approach to glove box monitoring that involves drawing air out of one glove port through a detection grid that collects ions created in the air inside the glove box by ionizing radiation, especially alpha radiation. The charge deposited on the detection grid by the ions is measured with a sensitive electrometer. The air can be circulated back to the glove box through the other glove port, preventing contamination from leaving the glove box and detector system. Initial experiments using a mock-up constructed of sheet metal indicate that this technology provides the measurement technique needed to perform a defensible, non-invasive measurement of alpha contamination inside glove boxes destined for waste disposal. This can result in an enormous cost savings if a given glove box can be shown to fall into the catagory of Low-Level Waste rather than Trans-Uranic Waste. Considering that hundreds of glove boxes contaminated with plutonium will be taken out of service at various nuclear facilities over the next few years, the potential cost savings associated with disposal as LLW rather than TRU waste are substantial

The cake has icing, so we are not allowed to put it into the box upside down. V. G. Boltyansky asked this question in 1977 and showed that three pieces always suffice. In this paper we provide examples of cakes that cannot be cut into two pieces to be put into the box. This shows that three is the answer to Boltyansky's question.

  11. "I thought cancer was one of those random things. I didn't know cancer could be caught...": adolescent girls' understandings and experiences of the HPV programme in the UK.

    Science.gov (United States)

    Hilton, Shona; Smith, Emily

    2011-06-10

    The UK human papillomavirus (HPV) vaccination programme aims to provide girls aged 12-13 with protection against two of the most carcinogenic strains (types 16 and 18) of this sexually transmitted virus which together account for 70% of cases of cervical cancer. Despite evidence suggesting a general lack of knowledge about HPV and its link with cervical cancer, vaccine uptake rates were generally high in the UK for the first year of the HPV vaccination programme. In countries that implemented the HPV programme ahead of the UK, studies have found that girls' and parents' levels of awareness about HPV have increased since implementation of the programme but that knowledge continues to be limited. This study offers some of the first insights from the UK into adolescent girls' understandings of HPV, its link with cervical cancer, and experiences of vaccination, since the programme was introduced in September 2008. Eighteen focus groups were conducted between December 2009 and May 2010 with schoolgirls aged between 12 and 18 living in various parts of the UK. Eighty seven girls participated in these discussions. Typically, girls knew very little about HPV or how they could best protect themselves from HPV infection. Although many of the girls linked HPV to cancer, only half specifically associated it with cervical cancer. Most girls had no idea how long the vaccine would offer them protection. They assumed that HPV vaccination must be important for their health because it was recommended by people they trusted, namely parents and immunisation experts. Just over half of the girls were aware that in the future they would need to attend for cervical screening. Key concerns which girls expressed about HPV vaccination reflected their anxieties about needles, anticipated pain on injection, privacy during vaccination and fears about needle cleanliness. Our data point to a need to continue to address gaps in knowledge about HPV and to provide information to address girls

  14. Neurally and mathematically motivated architecture for language and thought.

    Science.gov (United States)

    Perlovsky, L I; Ilin, R

    2010-01-01

    Neural structures of interaction between thinking and language are unknown. This paper suggests a possible architecture motivated by neural and mathematical considerations. A mathematical requirement of computability imposes significant constraints on possible architectures consistent with brain neural structure and with a wealth of psychological knowledge. How language interacts with cognition. Do we think with words, or is thinking independent from language with words being just labels for decisions? Why is language learned by the age of 5 or 7, but acquisition of knowledge represented by learning to use this language knowledge takes a lifetime? This paper discusses hierarchical aspects of language and thought and argues that high level abstract thinking is impossible without language. We discuss a mathematical technique that can model the joint language-thought architecture, while overcoming previously encountered difficulties of computability. This architecture explains a contradiction between human ability for rational thoughtful decisions and irrationality of human thinking revealed by Tversky and Kahneman; a crucial role in this contradiction might be played by language. The proposed model resolves long-standing issues: how the brain learns correct words-object associations; why animals do not talk and think like people. We propose the role played by language emotionality in its interaction with thought. We relate the mathematical model to Humboldt's "firmness" of languages; and discuss possible influence of language grammar on its emotionality. Psychological and brain imaging experiments related to the proposed model are discussed. Future theoretical and experimental research is outlined.

If the assumption is violated, some forms of transformation should be taken to make the assumption approximately true. The Box-Cox transformation is a general transformation method which can be applied to many different types of data. The flexibility of the Box-Cox transformation is due to a variable, called transformation factor, appearing in the Box-Cox formula. We developed a maximum likelihood method that treats the transformation factor as an unknown parameter, which is estimated from the data simultaneously along with the QTL parameters. The method makes an objective choice of data transformation and thus can be applied to QTL analysis for many different types of data. Simulation studies show that (1) Box-Cox transformation can substantially increase the power of QTL detection; (2) Box-Cox transformation can replace some specialized transformation methods that are commonly used in QTL mapping; and (3) applying the Box-Cox transformation to data already normally distributed does not harm the result.

  16. Sport medicine and the ethics of boxing

    In the light of medical evidence of the health risks associated with boxing, a watchful agnostic position among sport physicians is no longer justifiable. The normal activity in a boxing match places the athletes at risk of head injury, some of which may be difficult to detect and impossible to repair. This suggests that sport physicians and others expert in the prevention and diagnosis of such injuries should take a public stand against boxing, as other medical associations have. Although there is a need for continuing research into the health risks, doctors can in the interim take steps to increase public awareness of these risks. Sport physicians in particular can make a strong public statement by also ending their professional involvement with boxing. This need not be interpreted as paternalism; doctors are qualified neither to make laws nor to restrict private behaviour. Sport physicians are, however, well equipped to advise those who do make laws and those who choose to engage in boxing. In the end, because this stance against boxing will probably reduce the number of brain injuries in certain athletes, autonomy will be preserved, rather than restricted.

    Boxing is one of the oldest combat sports. The aim of the current review is to critically analyze the amateur boxer's physical and physiological characteristics and to provide practical recommendations for training as well as new areas of scientific research. High-level male and female boxers show a propensity for low body fat levels. Although studies on boxer somatotypes are limited, the available information shows that elite-level male boxers are characterized by a higher proportion of mesomorphy with a well-developed muscle mass and a low body fat level. To help support the overall metabolic demands of a boxing match and to accelerate the recovery process between rounds, athletes of both sexes require a high level of cardiorespiratory fitness. International boxers show a high peak and mean anaerobic power output. Muscle strength in both the upper and lower limbs is paramount for a fighter's victory and is one of the keys to success in boxing. As boxing punches are brief actions and very dynamic, high-level boxing performance requires well-developed muscle power in both the upper and lower limbs. Albeit limited, the available studies reveal that isometric strength is linked to high-level boxing performance. Future investigations into the physical and physiological attributes of boxers are required to enrich the current data set and to help create a suitable training program.

    Tracking sample vials in a research environment is a critical task and doing so efficiently can have a large impact on productivity, especially in high volume laboratories. There are several challenges to automating the capture process, including the variety of containers used to store samples. We developed a fast and robust system to capture the location of sample vials being placed in storage that allows the laboratories the flexibility to use sample containers of varying dimensions. With a single scan, this device captures the box identifier, the vial identifier and the location of each vial within a freezer storage box. The sample vials are tracked through a barcode label affixed to the cap while the boxes are tracked by a barcode label on the side of the box. Scanning units are placed at the point of use and forward data to a sever application for processing the scanned data. Scanning units consist of an industrial barcode reader mounted in a fixture positioning the box for scanning and providing lighting during the scan. The server application transforms the scan data into a list of storage locations holding vial identifiers. The list is then transferred to the laboratory database. The box vial scanner captures the IDs and location information for an entire box of sample vials into the laboratory database in a single scan. The system accommodates a wide variety of vials sizes by inserting risers under the sample box and a variety of storage box layouts are supported via the processing algorithm on the server.

  19. Minimum airflow reset of single-duct VAV terminal boxes

    Science.gov (United States)

    Cho, Young-Hum

    Single duct Variable Air Volume (VAV) systems are currently the most widely used type of HVAC system in the United States. When installing such a system, it is critical to determine the minimum airflow set point of the terminal box, as an optimally selected set point will improve the level of thermal comfort and indoor air quality (IAQ) while at the same time lower overall energy costs. In principle, this minimum rate should be calculated according to the minimum ventilation requirement based on ASHRAE standard 62.1 and maximum heating load of the zone. Several factors must be carefully considered when calculating this minimum rate. Terminal boxes with conventional control sequences may result in occupant discomfort and energy waste. If the minimum rate of airflow is set too high, the AHUs will consume excess fan power, and the terminal boxes may cause significant simultaneous room heating and cooling. At the same time, a rate that is too low will result in poor air circulation and indoor air quality in the air-conditioned space. Currently, many scholars are investigating how to change the algorithm of the advanced VAV terminal box controller without retrofitting. Some of these controllers have been found to effectively improve thermal comfort, indoor air quality, and energy efficiency. However, minimum airflow set points have not yet been identified, nor has controller performance been verified in confirmed studies. In this study, control algorithms were developed that automatically identify and reset terminal box minimum airflow set points, thereby improving indoor air quality and thermal comfort levels, and reducing the overall rate of energy consumption. A theoretical analysis of the optimal minimum airflow and discharge air temperature was performed to identify the potential energy benefits of resetting the terminal box minimum airflow set points. Applicable control algorithms for calculating the ideal values for the minimum airflow reset were developed and

    This study sought to replicate and extend investigations of current models of sexual dysfunction (Barlow, 2002; Janssen, Everaerd, Spiering, & Janssen, 2000) which implicate factors such as spectatoring, failure to use ameliorative strategies, and information processing biases in the development and persistence of sexual difficulties. A sample of 165 (n = 71 men) undergraduates completed measures of sexual dysfunction and relationship satisfaction, and reported on the content and frequency of non-erotic thoughts during sex with a partner (i.e., spectatoring), the emotional impact of non-erotic thoughts, and the strategies used to manage them. They also reported on their main sexual functioning difficulties and the strategies they used to manage those difficulties. Finally, participants were presented with a series of hypothetical sexual scenarios and were asked to report their immediate interpretation of events in the scenario. The content of non-erotic thoughts was similar to previous work (Purdon & Holdaway, 2006), although gender differences in thought content were less pronounced. As in previous research, greater frequency of, and anxiety evoked by, non-erotic thoughts was associated with poorer sexual functioning, but we found that this was over and above relationship satisfaction. Participants both high and low in sexual functioning reported using a variety of strategies to manage their non-erotic thoughts, thought suppression being the least effective, and also used a variety of strategies to manage sexual difficulties. Poorer sexual functioning was associated with more negative interpretations of ambiguous sexual scenarios, but this was mediated by relationship satisfaction. However, positive interpretations were predicted by sexual functioning. Results were discussed in terms of their theoretical and clinical implications.

    Full Text Available The paper analyzes variations in the temperature of axle-box heating of railroad rolling stock considering two modes of the train - driving and parking position. Additionally, the article describes the influence of the axle load and season on the heat of the axle-box, forecasts intolerable residual resources and explains a possibility of detecting likely breakage at the very beginning of defects. The paper also deals with scientific literature related to axle-box heating and focuses on the conducted practical and theoretical experiments. The carried out research has established the rates of operating heating and critical heating. The application of numerical values for the algorithm of automatic control devices could help with detecting the breakdowns of the axle-box before they reach a critical state and assist in forecasting residual operating resources.

    Introduction of the invasive Africanized honey bee (AHB) into the Neotropics is a serious problem for many cavity nesting birds, specifically parrots. These bees select cavities that are suitable nest sites for birds, resulting in competition. The difficulty of removing bees and their defensive behavior makes a prevention protocol necessary. Here, we describe a push-pull integrated pest management protocol to deter bees from inhabiting bird boxes by applying a bird safe insecticide, permethrin, to repel bees from nest boxes, while simultaneously attracting them to pheromone-baited swarm traps. Shown here is an example experiment using Barn Owl nest boxes. This protocol successfully reduced colonization of Barn Owl nest boxes by Africanized honey bees. This protocol is flexible, allowing adjustments to accommodate a wide range of bird species and habitats. This protocol could benefit conservation efforts where AHB are located.

  3. Adobe Boxes: Locating Object Proposals Using Object Adobes.

    Despite the previous efforts of object proposals, the detection rates of the existing approaches are still not satisfactory enough. To address this, we propose Adobe Boxes to efficiently locate the potential objects with fewer proposals, in terms of searching the object adobes that are the salient object parts easy to be perceived. Because of the visual difference between the object and its surroundings, an object adobe obtained from the local region has a high probability to be a part of an object, which is capable of depicting the locative information of the proto-object. Our approach comprises of three main procedures. First, the coarse object proposals are acquired by employing randomly sampled windows. Then, based on local-contrast analysis, the object adobes are identified within the enlarged bounding boxes that correspond to the coarse proposals. The final object proposals are obtained by converging the bounding boxes to tightly surround the object adobes. Meanwhile, our object adobes can also refine the detection rate of most state-of-the-art methods as a refinement approach. The extensive experiments on four challenging datasets (PASCAL VOC2007, VOC2010, VOC2012, and ILSVRC2014) demonstrate that the detection rate of our approach generally outperforms the state-of-the-art methods, especially with relatively small number of proposals. The average time consumed on one image is about 48 ms, which nearly meets the real-time requirement.

    The aim of this study was to devise a valid performance analysis system for the assessment of the movement characteristics associated with competitive amateur boxing and assess its reliability using analysts of varying experience of the sport and performance analysis. Key performance indicators to characterise the demands of an amateur contest (offensive, defensive and feinting) were developed and notated using a computerised notational analysis system. Data were subjected to intra- and inter-observer reliability assessment using median sign tests and calculating the proportion of agreement within predetermined limits of error. For all performance indicators, intra-observer reliability revealed non-significant differences between observations (P > 0.05) and high agreement was established (80-100%) regardless of whether exact or the reference value of ±1 was applied. Inter-observer reliability was less impressive for both analysts (amateur boxer and experienced analyst), with the proportion of agreement ranging from 33-100%. Nonetheless, there was no systematic bias between observations for any indicator (P > 0.05), and the proportion of agreement within the reference range (±1) was 100%. A reliable performance analysis template has been developed for the assessment of amateur boxing performance and is available for use by researchers, coaches and athletes to classify and quantify the movement characteristics of amateur boxing.

  6. DSMC simulations of vapor transport toward development of the lithium vapor box divertor concept

    Jagoe, Christopher; Schwartz, Jacob; Goldston, Robert

    2016-10-01

    The lithium vapor divertor box concept attempts to achieve volumetric dissipation of the high heat efflux from a fusion power system. The vapor extracts the heat of the incoming plasma by ionization and radiation, while remaining localized in the vapor box due to differential pumping based on rapid condensation. Preliminary calculations with lithium vapor at densities appropriate for an NSTX-U-scale machine give Knudsen numbers between 0.01 and 1, outside both the range of continuum fluid dynamics and of collisionless Monte Carlo. The direct-simulation Monte Carlo (DSMC) method, however, can simulate rarefied gas flows in this regime. Using the solver contained in the OpenFOAM package, pressure-driven flows of water vapor will be analyzed. The use of water vapor in the relevant range of Knudsen number allows for a flexible similarity experiment to verify the reliability of the code before moving to tests with lithium. The simulation geometry consists of chains of boxes on a temperature gradient, connected by slots with widths that are a representative fraction of the dimensions of the box. We expect choked flow, sonic shocks, and order-of-magnitude pressure and density drops from box to box, but this expectation will be tested in the simulation and then experiment.

    Current strategies for increased physical activity and exercise in individuals with spinal cord injury (SCI) face many challenges with regards to maintaining their continuity of participation. Barriers cited often include problems with accessing facilities, mundane, monotonous or boring exercises and expensive equipment that is often not adapted for wheelchair users. To compare the physiological responses and user preferences between conventional heavy-bag boxing against a novel form of video game boxing, known as exergaming boxing. Cross-sectional study. Exercise laboratory setting in a university medical center. Seventeen participants with SCI were recruited, of which sixteen were male and only one female. Their mean age was 35.6±10.2 years. All of them performed a 15-minute physical exercise session of exergaming and heavy-bag boxing in a sitting position. The study assessed physiological responses in terms of oxygen consumption, metabolic equivalent (MET) and energy expenditure between exergaming and heavy-bag boxing derived from open-circuit spirometry. Participants also rated their perceived exertion using Borg's category-ratio ratings of perceived exertion. Both exergaming (MET: 4.3±1.0) and heavy-bag boxing (MET: 4.4±1.0) achieved moderate exercise intensities in these participants with SCI. Paired t-test revealed no significant differences (P>0.05, Cohen's d: 0.02-0.49) in the physiological or perceived exertional responses between the two modalities of boxing. Post session user survey reported all the participants found exergaming boxing more enjoyable. Exergaming boxing, was able to produce equipotent physiological responses as conventional heavy-bag boxing. The intensity of both exercise modalities achieved recommended intensities for health and fitness benefits. Exergaming boxing have the potential to provide an enjoyable, self-competitive environment for moderate-vigorous exercise even at the comfort of their homes.

    2001-01-01

    The main objective was to undertake a literature review in support of NII's ongoing work in improving safety in the nuclear industry to help define suitable standards of cleanliness for plutonium glove boxes. This is to cover the following areas: existing or proposed national/international standards relating to plutonium glove box cleanliness management; practicable metrology options for assessing the plutonium content of glove boxes; any available dose information relating to the operation of modern and 'old design'; current contamination levels of specific significance (i.e. any accepted level in decommissioning/waste terms, typical criticality limits (if available), any box plutonium loadings that are documented with corresponding operator doses etc.); and, techniques for the decontamination of plutonium glove boxes and their relative effectiveness. This should then form the basis of any further development work undertaken by the UK nuclear industry. Main recommendations are as follows: 1) No information could be found in open literature on acceptable levels of contamination in boxes and action levels for cleanup. If these are not available in closed publications the 2) Where possible, the decontamination methods identified should be tested and dose information recorded against each method to allow informed decisions on which is the optimum technique for a particular form of contamination. 3) Consideration should be given to utilisation of metrology options which have the lowest potential for exposure of operators. Preferred options, may be detection from the outside of boxes using hand-held or permanently located radiation detectors, or semi-intrusive methods such as air-ionisation readings which would require one-off installation of detectors in ductwork

    Scientists have to get out of the ivory tower and tell society, which ultimately finances them, about their work, their results, and implications, be they good or bad. This is commonly accepted ethics. But how would you "tell society" at large what you are doing? Scientific work typically is difficult to confer to lay people, and finding suitable simplifications and paraphrasings requires considerable effort. Estimating societal implications is dangerous as swimming with sharks, some of which are your own colleagues. Media tend to be not always interested - unless results are particularly spectacular, well, in a press sense. Again, sharks are luring. All this makes informing the public a tedious, time-consuming task which tends to receive not much appreciation in tenure negotiations where indexed publications are the first and foremost measure.As part of the EU funded EarthServer initiative we tried it. Having promised a "video about the project" we found it boring to do another 10 minute repetition from the grant contract and started aiming at a full TV documentary explaining "Big Earth Data" to the interested citizens. It took more than one year to convince a TV producing company and TV stations that this is not another feature about the beauty of nature or catastrophies, but a bout human insight from computer-supported sifting through all those observations and simulations available. After they got the gist they were fully on board and supported financially with a substantial amount. The final 53 minutes "Big Earth Data" movie was broadcast in February 2015 in German and French (English version available from ). Several smaller spin-off features originated around it, such as an uptake of the theme (and material) in a popular German science TV series.Of course, this is but one contribution and cannot be made a continuous activity. In the talk we want to present and discuss the "making of" from a scientist's perspective, highlighting the ups and downs in the process, in the hope that it contributes to our profession's quest for materializing its scientific outreach promise.

    Full Text Available Skepticism has been expressed concerning the possibility to understand others’ intentions by simply observing their movements: Since a number of different intentions may have produced a particular action, motor information – it has been argued - might be sufficient to understand what an agent is doing, but not her remote goal in performing that action. Here we challenge this conclusion by showing that in the absence of contextual information, intentions can be inferred from body movement. Based on recent empirical findings, we shall contend that: i intentions translate into differential kinematic patterns; ii observers are especially attuned to kinematic information and can use early differences in visual kinematics to anticipate the intention of an agent in performing a given action; iii during interacting activities, predictions about the future course of others’ actions tune online action planning; iv motor activation during action observation subtends a complementary understanding of what the other is doing. These findings demonstrate that intention understanding is deeply rooted in social interaction: by simply observing others’ movements, we might know what they have in mind to do and how we should act in response.

  17. Thought beyond language: neural dissociation of algebra and natural language.

    Monti, Martin M; Parsons, Lawrence M; Osherson, Daniel N

    2012-08-01

    A central question in cognitive science is whether natural language provides combinatorial operations that are essential to diverse domains of thought. In the study reported here, we addressed this issue by examining the role of linguistic mechanisms in forging the hierarchical structures of algebra. In a 3-T functional MRI experiment, we showed that processing of the syntax-like operations of algebra does not rely on the neural mechanisms of natural language. Our findings indicate that processing the syntax of language elicits the known substrate of linguistic competence, whereas algebraic operations recruit bilateral parietal brain regions previously implicated in the representation of magnitude. This double dissociation argues against the view that language provides the structure of thought across all cognitive domains.

    A fuel channel box has a square cylindrical shape and, in the transversal cross sectional shape, the wall thickness of a corner portion is greater than that of a central portion of the side wall except for an upper portion thereof. The upper portion of the channel box includes a region to be in contact with an upper lattice plate and a region to attach a channel spacer. Then, the wall thickness of these regions is uniform in the transversal cross section and they have the same wall thickness with that of the corner portion which has the increased wall thickness. With such a constitution, the upper portion of the channel box receives a counter force applied from the upper lattice plate upon occurrence of earthquakes and moderate it to reduce local stresses and deformation. Further, a similar region with increased wall thickness is disposed also to the lower portion of the channel box, thereby enabling to suppress the amount of coolants leaked from a portion between the lower portion and a lower tie plate, and improve the mechanical integrity of the channel box.

    An important goal in drug regulation is understanding serious safety issues with new drugs as soon as possible. Achieving this goal requires us to understand whether information provided during the Food and Drug Administration (FDA) drug review can predict serious safety issues that are usually identified after the product is approved. However, research on this topic remains understudied. In this paper, we examine whether any pre-marketing drug characteristics are associated with serious post-marketing safety actions. We study this question using an internal FDA database containing every new small molecule drug submitted to the FDA's Center for Drug Evaluation and Research (CDER) on or after November 21, 1997, and approved and commercially launched before December 31, 2009. Serious post-marketing safety actions include whether these drugs ever experienced either a post-marketing boxed warning or a withdrawal from the market due to safety concerns. A random effects logistic regression model was used to test whether any pre-marketing characteristics were associated with either post-marketing safety action. A total of 219 new molecular entities were analyzed. Among these drugs, 11 experienced a safety withdrawal and 30 received boxed warnings by July 31, 2016. Contrary to prevailing hypotheses, we find that neither clinical trial sample sizes nor review time windows are associated with the addition of a post-marketing boxed warning or safety withdrawal. However, we do find that new drugs approved with either a boxed warning or priority review are more likely to experience post-marketing boxed warnings. Furthermore, drugs approved with boxed warnings tend to receive post-marketing boxed warnings resulting from new safety information that are unrelated to the original warning. Drugs approved with a boxed warning are 3.88 times more likely to receive a post-marketing boxed warning, while drugs approved with a priority review are 3.51 times more likely to receive a post

Raindrops in this demonstration are represented by acrylic spheres arranged on pillars within a cubic volume. Defocused imaging with a camera or the eye reveals a mosaic rainbow (segment) when viewed and illuminated in the appropriate fashion.

  3. Reassessment of the nonlocality of correlation boxes

    Energy Technology Data Exchange (ETDEWEB)

    Costa, A.P.; Parisio, Fernando, E-mail: parisio@df.ufpe.br

    2017-01-15

    Correlation boxes are hypothetical systems usually designed to produce the maximal algebraic violation of a Bell inequality, beyond the quantum bound and without superluminal signalling. The fact that these systems show stronger correlations than those presented by maximally entangled quantum states, as the spin singlet, has been regarded as a demonstration that the former are more nonlocal than the latter. By applying an alternative, consistent measure of nonlocality to a family of correlation boxes, we show that this conclusion is not necessarily true. Complementarily, we define a class of systems displaying subquantum correlations which, nevertheless, are more nonlocal than the singlet state, showing that the extent of the numeric violation of an inequality may have little to do with the degree of nonlocality, especially in the case of correlation boxes.

    Highlights: •A quantum Lévy process in a box involves topological constraints in space. •The eigenvalue problem is formulated for the Lévy process in the box. •The path integral formalism with the Lévy measure is constructed. •The evolution operator is obtained in the path integral presentation. -- Abstract: It is shown that a quantum Lévy process in a box leads to a problem involving topological constraints in space, and its treatment in the framework of the path integral formalism with the Lévy measure is suggested. The eigenvalue problem for the infinite potential well is properly defined and solved. An analytical expression for the evolution operator is obtained in the path integral presentation, and the path integral takes the correct limit of the local quantum mechanics with topological constraints. An example of the Lévy process in oscillating walls is also considered in the adiabatic approximation

    2016-04-01

    The relationship between culture, language, and thought has long been one of the most important topics for those who wish to understand the nature of human cognition. This issue has been investigated for decades across a broad range of research disciplines. However, there has been scant communication across these different disciplines, a situation largely arising through differences in research interests and discrepancies in the definitions of key terms such as 'culture,' 'language,' and 'thought.' This article reviews recent trends in research on the relation between language, culture and thought to capture how cognitive psychology and cultural psychology have defined 'language' and 'culture,' and how this issue was addressed within each research discipline. We then review recent research conducted in interdisciplinary perspectives, which directly compared the roles of culture and language. Finally, we highlight the importance of considering the complex interplay between culture and language to provide a comprehensive picture of how language and culture affect thought.

  12. Fire test of DOT 7A Boxes

    International Nuclear Information System (INIS)

    Jensen, J.D.

    1979-05-01

    The primary objective of conducting the full-scale fire tests of the DOT (Department of Transportation) 7A FRP Boxes was to provide information to assist in quantifying the fire hazard of the storage located at the Radioactive Waste Management Complex (RWMC), and to learn if changing the storage array will decrease the fire risk. Also, the level of fire fighting and fire protection required to maintain the risk at the RWMC within acceptable DOE guidelines was investigated. Two full-scale fire tests were conducted at Southwest Research Institute (SwRI) in June 1978, using the DOE 7A FRP Plywood Storage Containers. The fire tests showed that when subjected to a substantial ignition source, the boxes will propagate fire as long as no fire-suppression measures are taken. Fire will breach the boxes and spread the radioactive contaminated waste if it is not extinguished. As the fire progresses, additional boxes will become involved, and eventually the entire storage array will ignite. It is recommended that the use of DOT 7A Boxes be discontinued and replaced with noncombustible storage containers. In the event this is not practicable, guidance recommendations are presented to minimize the large fire loss potential. It is also recommended that an investigation be conducted into the number of boxes that can be destroyed and still maintain a safe environment for employees and the public. This investigation should include how far radioactive contamination will spread, what cleanup will be required, anticipated exposure of the people within the area, and the public impact of such a fire

    While the potential benefits of smart home technology are widely recognized, a lightweight design is needed for the benefits to be realized at a large scale. We introduce the CASAS "smart home in a box", a lightweight smart home design that is easy to install and provides smart home capabilities out of the box with no customization or training. We discuss types of data analysis that have been performed by the CASAS group and can be pursued in the future by using this approach to designing and implementing smart home technologies.

  14. Opening Pandora's Box: The impact of open system modeling on interpretations of anoxia

    Science.gov (United States)

    Hotinski, Roberta M.; Kump, Lee R.; Najjar, Raymond G.

    2000-06-01

    The geologic record preserves evidence that vast regions of ancient oceans were once anoxic, with oxygen levels too low to sustain animal life. Because anoxic conditions have been postulated to foster deposition of petroleum source rocks and have been implicated as a kill mechanism in extinction events, the genesis of such anoxia has been an area of intense study. Most previous models of ocean oxygen cycling proposed, however, have either been qualitative or used closed-system approaches. We reexamine the question of anoxia in open-system box models in order to test the applicability of closed-system results over long timescales and find that open and closed-system modeling results may differ significantly on both short and long timescales. We also compare a scenario with basinwide diffuse upwelling (a three-box model) to a model with upwelling concentrated in the Southern Ocean (a four-box model). While a three-box modeling approach shows that only changes in high-latitude convective mixing rate and character of deepwater sources are likely to cause anoxia, four-box model experiments indicate that slowing of thermohaline circulation, a reduction in wind-driven upwelling, and changes in high-latitude export production may also cause dysoxia or anoxia in part of the deep ocean on long timescales. These results suggest that box models must capture the open-system and vertically stratified nature of the ocean to allow meaningful interpretations of long-lived episodes of anoxia.

  15. Affective regulation of stereotype activation: It’s the (accessible) thought that counts

    Huntsinger, Jeffrey R.; Sinclair, Stacey; Dunn, Elizabeth; Clore, Gerald L.

    2010-01-01

    Extant research demonstrates that positive affect, compared to negative affect, increases stereotyping. In four experiments we explore whether the link between affect and stereotyping depends, critically, on the relative accessibility of stereotype-relevant thoughts and response tendencies. As well as manipulating mood, we measured or manipulated the accessibility of egalitarian response tendencies (Experiments 1-2) and counter-stereotypic thoughts (Experiments 3-4). In the absence of such response tendencies and thoughts, people in positive moods displayed greater stereotype activation —consistent with past research. By contrast, in the presence of accessible egalitarian response tendencies or counter-stereotypic thoughts, people in positive moods exhibited less stereotype activation than those in negative moods.

  17. Thoughts in flight: automation use and pilots' task-related and task-unrelated thought.

    Science.gov (United States)

    Casner, Stephen M; Schooler, Jonathan W

    2014-05-01

    The objective was to examine the relationship between cockpit automation use and task-related and task-unrelated thought among airline pilots. Studies find that cockpit automation can sometimes relieve pilots of tedious control tasks and afford them more time to think ahead. Paradoxically, automation has also been shown to lead to lesser awareness. These results prompt the question of what pilots think about while using automation. A total of 18 airline pilots flew a Boeing 747-400 simulator while we recorded which of two levels of automation they used. As they worked, pilots were verbally probed about what they were thinking. Pilots were asked to categorize their thoughts as pertaining to (a) a specific task at hand, (b) higher-level flight-related thoughts (e.g.,planning ahead), or (c) thoughts unrelated to the flight. Pilots' performance was also measured. Pilots reported a smaller percentage of task-at-hand thoughts (27% vs. 50%) and a greater percentage of higher-level flight-related thoughts (56% vs. 29%) when using the higher level of automation. However, when all was going according to plan, using either level of automation, pilots also reported a higher percentage of task-unrelated thoughts (21%) than they did when in the midst of an unsuccessful performance (7%). Task-unrelated thoughts peaked at 25% when pilots were not interacting with the automation. Although cockpit automation may provide pilots with more time to think, it may encourage pilots to reinvest only some of this mental free time in thinking flight-related thoughts. This research informs the design of human-automation systems that more meaningfully engage the human operator.

    To determine the Box and Block Test norm in a sub-Saharan population and to compare these data with published norms for North American adults. A total of 692 healthy Beninese people, age range 20-85 years, were recruited. These subjects were asked to perform the Box and Block Test with both hands. Box and Block Test scores (mean and standard deviation (SD)) for women and men were, respectively, 81.3 (15.4) and 79 (16.6) for the dominant hand and 73.2 (13.7) and 72 (14.8) for the non-dominant hand. Mean Box and Block Test scores ranged from 89.1 (12.7) for people under the age of 25 years to 55.23 (10.5) for people over the age of 74 years. Manual dexterity was better for women than men, for dominant hand than non-dominant hand, and for younger subjects. In comparison with published results for US subjects, Beninese subjects had better dexterity below the age of 50 years in both sexes for the right hand and worse dexterity over 64 years of age in both sexes for the right hand. Developing and validating outcome scales in Africa will help to improve functional assessment of African populations in clinical practice and research.

    We propose to study hadron-hadron scattering using lattice QCD in an asymmetric box which allows one to access more non-degenerate low-momentum modes for a given volume. The conventional Luescher's formula applicable in a symmetric box is modified accordingly. To illustrate the feasibility of this approach, pion-pion elastic scattering phase shifts in the I = 2, J = 0 channel are calculated within quenched approximation using improved gauge and Wilson fermion actions on anisotropic lattices in an asymmetric box. After the chiral and continuum extrapolation, we find that our quenched results for the scattering phase shifts in this channel are consistent with the experimental data when the three-momentum of the pion is below 300MeV. Agreement is also found when compared with previous theoretical results from lattice and other means. Moreover, with the usage of asymmetric volume, we are able to compute the scattering phases in the low-momentum range (pion three momentum less than about 350MeV in the center of mass frame) for over a dozen values of the pion three-momenta, much more than using the conventional symmetric box with comparable volume

  3. Safety evaluation for packaging CPC metal boxes

    1995-01-01

    This Safety Evaluation for Packaging (SEP) provides authorization for the use of Container Products Corporation (CPC) metal boxes, as described in this document, for the interarea shipment of radioactive contaminated equipment and debris for storage in the Central Waste Complex (CWC) or T Plant located in the 200 West Area. Authorization is granted until November 30, 1995. The CPC boxes included in this SEP were originally procured as US Department of Transportation (DOT) Specification 7A Type A boxes. A review of the documentation provided by the manufacturer revealed the documentation did not adequately demonstrate compliance to the 4 ft drop test requirement of 49 CFR 173.465(c). Preparation of a SEP is necessary to document the equivalent safety of the onsite shipment in lieu of meeting DOT packaging requirements until adequate documentation is received. The equivalent safety of the shipment is based on the fact that the radioactive contents consist of contaminated equipment and debris which are not dispersible. Each piece is wrapped in two layers of no less than 4 mil plastic prior to being placed in the box which has an additional 10 mil liner. Pointed objects and sharp edges are padded to prevent puncture of the plastic liner and wrapping

    2003-06-01

    To examine the relationship between thought-action fusion (TAF) and schizotypy. In two separate samples of undergraduate students (Ns = 77 and 64), correlations were computed between a measure of TAF and indices of schizotypy and fantasy proneness. Positive correlations were found between TAF and various aspects of schizotypy (i.e. perceptual aberration, magical ideation, schizotypal personality characteristics, disposition to hallucinate). However, correlations between TAF and schizotypy no longer attained significance when controlling for fantasy proneness. At least in the non-clinical population, the connection between TAF and schizotypy seems to be a by-product of fantasy-prone individuals' tendency to report unusual experiences.

    1997-11-01

    Subjects were shown a short film fragment. Following this, one group of subjects (n = 26) was instructed to suppress their thoughts about the film, while the other group (n = 24) received no instructions. After 5 hrs subjects returned to the laboratory and completed a questionnaire testing their memory about the film. Results showed that suppression subjects reported a higher frequency of thoughts about the film than control subjects. No evidence was obtained for Wegner, Quillian, and Houston's (1996; Journal of Personality and Social Psychology, 71, 680-691) claim that suppression has an undermining effect on memory for chronology. Possible causes for the differences between the results as obtained by Wegner et al., and those found in the present study are discussed. These causes may pertain to the experimental design, but also to differences in emotional impact of the stimulus material that was used in both studies.

    Full Text Available Poetry of Momcilo Nastasijevic gives us undoubted motive to talk about him as a consistent religious poet, a poet of orthodox religious inspiration. He approached towards words as sanctity, he endeavoured to measure each word, reach it, and clean it from accumulated dust of everyday’s blather. His attitude towards poetical locution, his personal law of poetical perfection, represents, brought up to the last consequences, principles of symbolist poetics. He thought of words as magic of sound and rhythm and examines all the effects we can get from it. To him, poetry was identical to crucial and the purest flickering of what he called human soul. The thought of our poet come down to essence of his poetry: who has understood his poems, can be sure that will understand Nastasijevic as a poet.

    2015-12-01

    Full Text Available Abstract Current efforts to teach and research the historical foundations of IPE thought in classical political economy in the 18th, 19th and early 20th centuries centre largely on European and American thinkers. If a more extensive 'global conversation' is to be fostered in the field today, the perspectives of thinkers in other regions need to be recognised, and brought into the mainstream of its intellectual history. As a first step towards 'globalising' the classical foundations of IPE thought, this article demonstrates some ways in which thinkers located beyond Europe and the United States engaged with and contributed to debates associated with the three well-known classical traditions on which current IPE scholarship often draws: economic liberalism, economic nationalism and Marxism. It also reveals the extensive nature of 'global conversations' about IPE issues in this earlier era.

    In creating the value-added product in not distant future, it is necessary and inevitable to establish a holistic and though-evoking approach to the engineering problem, which should be at least associated with the inter-disciplinary knowledge and thought processes across the whole engineering spheres. It is furthermore desirable to integrate it with trans-disciplinary aspects ranging from manufacturing culture, through liberal-arts engineering, and industrial sociology.   The thought-evoking approach can be exemplified and typified by representative engineering problems: unveiling essential features in ‘Tangential Force Ratio and Interface Pressure’, prototype development for ‘Bio-mimetic Needle’ and application of ‘Water-jet Machining to Artificial Hip Joint’, product innovation in ‘Heat Sink for Computer’, application of ‘Graph Theory’ to similarity evaluation of production systems, leverage among reciprocity attributes in ‘Industrial and Engineering Designs for Machine Enclosure’,...

    This thesis argues that Nietzsche’s thought takes two paths toward overcoming the nihilism of modern culture. It shows that affirmation is alternatively conceived as a revaluation of life and as a transfiguration of it, introducing an ambiguity at the heart of Nietzsche’s philosophy. Nietzsche’s aspiration to cultural regeneration prevents him from recognising the implications of affirmation as it is best conceived, as transfiguration, an aesthetic condition that cannot be imposed or designed...

  20. Language as an instrument of thought

    Eran Asoulin

    2016-11-01

    Full Text Available I show that there are good arguments and evidence to boot that support the language as an instrument of thought hypothesis. The underlying mechanisms of language, comprising of expressions structured hierarchically and recursively, provide a perspective (in the form of a conceptual structure on the world, for it is only via language that certain perspectives are available to us and to our thought processes. These mechanisms provide us with a uniquely human way of thinking and talking about the world that is different to the sort of thinking we share with other animals. If the primary function of language were communication then one would expect that the underlying mechanisms of language will be structured in a way that favours successful communication. I show that not only is this not the case, but that the underlying mechanisms of language are in fact structured in a way to maximise computational efficiency, even if it means causing communicative problems. Moreover, I discuss evidence from comparative, neuropathological, developmental, and neuroscientific evidence that supports the claim that language is an instrument of thought.

    Full Text Available This study follows two aims: one to review some late views on the relations among language, thought, and culture; and the other, to offer a new strategy, in a novel model, based on last achievements in the minimalist approach. Studying views and arguments, three dichotomies are discussed: 1 the views which confirm the relation between culture and language in opposition to the views that deny this; 2 distinguishing the symmetry-procedural view and the transforming views of language; and 3 distinction among the social-communicational, and the biological-genetic motivations of language. The hypothesis for the novel strategy is that considering what the minimalist program has offered, especially from 2000 onwards, it is possible that language affects thought, while coding the and that culture affects language (which is called ethno-grammar . This is in addition to the biological-genetic base. From this point of view, language’s main function is neither to provide communication, nor to express thought, but to connect cognitive and socio-cultural terminals together.

  2. Contaminants in ventilated filling boxes

    Bolster, D. T.; Linden, P. F.

    While energy efficiency is important, the adoption of energy-efficient ventilation systems still requires the provision of acceptable indoor air quality. Many low-energy systems, such as displacement or natural ventilation, rely on temperature stratification within the interior environment, always extracting the warmest air from the top of the room. Understanding buoyancy-driven convection in a confined ventilated space is key to understanding the flow that develops with many of these modern low-energy ventilation schemes. In this work we study the transport of an initially uniformly distributed passive contaminant in a displacement-ventilated space. Representing a heat source as an ideal sourced of buoyancy, analytical and numerical models are developed that allow us to compare the average efficiency of contaminant removal between traditional mixing and modern low-energy systems. A set of small-scale analogue laboratory experiments was also conducted to further validate our analytical and numerical solutions.We find that on average traditional and low-energy ventilation methods are similar with regard to pollutant flushing efficiency. This is because the concentration being extracted from the system at any given time is approximately the same for both systems. However, very different vertical concentration gradients exist. For the low-energy system, a peak in contaminant concentration occurs at the temperature interface that is established within the space. This interface is typically designed to sit at some intermediate height in the space. Since this peak does not coincide with the extraction point, displacement ventilation does not offer the same benefits for pollutant flushing as it does for buoyancy removal.

    To examine the significance of thought-action fusion (TAF) and thought suppression tendencies, the present study obtained pre- and post-treatment questionnaire data on these constructs in a sample of OCD patients (n=24) and non-OCD anxiety patients (n=20). Results indicate that TAF and suppression are correlated with severity of psychopathology. Yet, the associations between TAF and psychopathology are not typical for OCD, but do also occur in other anxiety disorders (e.g., panic disorder, post traumatic stress disorder, and social phobia). As well, mean scores on the TAF and thought suppression measures dropped significantly from pre- to post-treatment, indicating that TAF and thought suppression are susceptible to change during psychotherapy.

    Although an inflated sense of responsibility, thought-action fusion, and thought suppression are influential factors in cognitive models of obsessive-compulsive disorder (OCD), their impact on OCD has generally been demonstrated in samples from Western countries. The aim of the present study is to evaluate these cognitive factors in Turkish patients with OCD, other anxiety disorders, and community controls. Group comparisons showed that responsibility based on self-dangerousness and thought suppression significantly distinguished OCD patients from patients with other anxiety disorders and controls. Moreover, correlation and discriminant function analyses indicated that thought-action fusion in morality and likelihood was also associated with OCD symptoms. The present findings provide support for the international validity and specificity of cognitive factors and model for OCD.

    Full Text Available Use of nest-boxes for management of cavity nesting birds in anthropic areas can give good results. In November 1987, data collection begun in UNICAMP, Campinas (São Paulo, with the objective of favouring establishment and increase in urban bird communities. The House Wren (Troglodytes aedon Viellot. 1807 and House Sparrow (Passer domesticus Linnaeus, 1758 used the nest boxes for reproduction. Nests were collected and analysed (weight, used materials, incubation chamber materials, nest form. House Sparrow used thin materials, like straw, paper and plastic, while house wren used heavy materials, like sticks, wire and tabs of soff drink cans. The nest-boxes offered favorable conditions to bird reproduction and protection in disturbed areas, and showed signs of leading to increase in diversity of species, that might use this nest-boxes for reproduction in the future.

    A ballast system is disclosed for a glove box including a fixed platform on which is mounted an inflatable bag on top of which resides a cover and a weight. The variable gas volume of the inflatable bag communicates with that of the glove box via a valved tube. The weight and the gas volume are selected to maintain a relatively constant pressure in the glove box despite variations in the glove box volume while avoiding the use of complicated valving apparatus.

    2017-01-01

    Background: Given their highly unacceptable nature, negative intrusions are likely to promote the experience of negative affect such as fear, shame and guilt. Moreover, moral thought-action fusion (believing that negative thinking is the equivalent of acting immorally) is likely to inflate the occurrence of negative affect when intrusions are experienced. In turn, negative affect is likely related to disclosure. The current study investigated whether thought-action fusion beliefs predict anti...

  9. Nopaline-type Ti plasmid of Agrobacterium encodes a VirF-like functional F-box protein.

    Lacroix, Benoît; Citovsky, Vitaly

    2015-11-20

    During Agrobacterium-mediated genetic transformation of plants, several bacterial virulence (Vir) proteins are translocated into the host cell to facilitate infection. One of the most important of such translocated factors is VirF, an F-box protein produced by octopine strains of Agrobacterium, which presumably facilitates proteasomal uncoating of the invading T-DNA from its associated proteins. The presence of VirF also is thought to be involved in differences in host specificity between octopine and nopaline strains of Agrobacterium, with the current dogma being that no functional VirF is encoded by nopaline strains. Here, we show that a protein with homology to octopine VirF is encoded by the Ti plasmid of the nopaline C58 strain of Agrobacterium. This protein, C58VirF, possesses the hallmarks of functional F-box proteins: it contains an active F-box domain and specifically interacts, via its F-box domain, with SKP1-like (ASK) protein components of the plant ubiquitin/proteasome system. Thus, our data suggest that nopaline strains of Agrobacterium have evolved to encode a functional F-box protein VirF.

    2017-12-01

    This article traces the history of the concept of dignity in Western thought, arguing that it became a formal Catholic theological concept only in the late nineteenth century. Three uses of the word are distinguished: intrinsic, attributed, and inflorescent dignity, of which, it is argued, the intrinsic conception is foundational. The moral norms associated with respect for intrinsic dignity are discussed briefly. The scriptural and theological bases for adopting the concept of dignity as a Christian idea are elucidated. The article concludes by discussing the relevance of this concept of dignity to the spiritual and ethical care of the dying.

    We study the quantum partition function of non-relativistic, ideal gas in a (non-cubical) box falling freely in arbitrary curved spacetime with center 4-velocity u{sup a}. When perturbed energy eigenvalues are properly taken into account, we find that corrections to various thermodynamic quantities include a very specific, sub-dominant term which is independent of kinematic details such as box dimensions and mass of particles. This term is characterized by the dimensionless quantity, Ξ=R{sub 0{sup ^}0{sup ^}}Λ{sup 2}, where R{sub 0{sup ^}0{sup ^}}=R{sub ab}u{sup a}u{sup b} and Λ=βℏc, and, quite intriguingly, produces Euler relation of homogeneity two between entropy and energy – a relation familiar from black hole thermodynamics.

    Despite evidence of elevated risk factors for suicidal thoughts and behavior in youth with Tourette syndrome and chronic tic disorders (CTD), few studies have actually examined that relationship. This study documented the frequency and clinical correlates of suicidal thoughts and behaviors in a sample of children and adolescents with CTD (N = 196, range 6-18 years old). The content is solely the responsibility of the authors and does not necessarily represent the official views of the Centers for Disease Control. Youth and parents completed a battery of measures that assessed co-occurring psychiatric diagnoses, child emotional and behavioral symptoms, and impairment due to tics or co-occurring conditions. A structured diagnostic interview identified that 19 youths with CTD (9.7%) experienced suicidal thoughts and/or behaviors, which was elevated compared to 3 youths (3%) who experienced these thoughts in a community control sample (N = 100, range 6-18 years old, P = .03). For youth with CTD, suicidal thoughts and behaviors were frequently endorsed in the context of anger and frustration. The Child Behavior Checklist (CBCL) anxious/depressed, withdrawn, social problems, thought problems, and aggressive behavior subscales, as well as the total internalizing problems scale, were associated with the presence of suicidal thoughts and/or behaviors. Suicidal thoughts and/or behaviors were significantly associated with tic symptom severity; tic-related impairment; and obsessive-compulsive, depressive, anxiety, and attention-deficit/hyperactivity disorders' symptom severity. CBCL anxiety/depression scores mediated the relationship between tic severity and suicidal thoughts and behaviors. Findings suggest that about 1 in 10 youth with CTD experience suicidal thoughts and/or behaviors, which are associated with a more complex clinical presentation and often occur in the presence of anger and frustration. © 2015 Wiley Periodicals, Inc.

  7. PCB-Based Break-Out Box

    Science.gov (United States)

    Lee, Jason H.

    2011-01-01

    Break-out boxes (BOBs) are necessary for all electrical integration/cable checkouts and troubleshooting. Because the price of a BOB is high, and no work can be done without one, often the procedure stops, simply waiting for a BOB. A less expensive BOB would take less time in the integration, testing, and troubleshooting process. The PCB-based BOB works and looks the same as a standard JPL BOB, called Gold Boxes. The only differences between the old BOB and the new PCB-based BOB is that the new one has 80 percent of its circuitry in a printed circuit board. This process reduces the time for fabrication, thus making the BOBs less expensive. Moreover, because of its unique design, the new BOBs can be easily assembled and fixed. About 80 percent of the new PCB-based BOB is in a $22 (at the time of this reporting) custom-designed, yet commercially available PCB. This device has been used successfully to verify that BOB cables were properly made. Also, upon completion, the BOB was beeped out via a multimeter to ensure that all sockets on the connectors were properly connected to the respective banana jack. When compared to the Gold Box BOBs, the new BOB has many advantages. It is much more cost efficient, it delivers equal usability at substantially lower cost of the BOB, and the Gold Box is much heavier when compared to the new BOB. The new BOB is also a bit longer and much more versatile in that connectors are easily changeable and if a banana jack is broken, it can be replaced instead of throwing away an entire BOB.

    Despite the inherent risks associated with exercise in general and boxing in particular, the sport has had a limited number of catastrophic cardiovascular events. Screening should be based on risks involved and become more extensive with the advancement of the athlete. Anatomic and electrophysiologic risks need to be assessed and may preclude participation with resultant life style and economic complications. There should be adequate preparation for the rare potential cardiovascular complication at all events, with the ability to rapidly assess and treat arrhythmias.

    2009-02-01

    To identify factors determining the clinical characteristics and prognosis of acute subdural hematoma (ASDH) arising from boxing injuries by comparing with ASDH due to any nonboxing cause. Two groups were selected for this study: 10 patients with ASDH because of boxing injuries and 26 patients with nonboxer ASDH. All of the patients underwent neurologic examination by neurosurgeons. Primary resuscitation and stabilization as well as operative therapy were performed to all patients according to the European Brain Injury Consortium Guidelines. Two groups were compared in terms of age, the Glasgow Coma Scale at admission, neurologic findings, craniogram and brain computed tomography scan findings, operative findings, and prognosis. As potential prognostic indicators for boxers, the time interval until surgery, the Glasgow Outcome Scale, hematoma thickness, midline shift, and the site of bleeding were analyzed. The characteristics of patients because of boxing injuries are that patients were younger, had lucid interval, and had no cerebral contusion or contralateral brain injury. There was no significant difference in initial Glasgow Coma Scale, hematoma thickness, midline shift, and their prognosis. The most peculiar clinical presentation of boxers' ASDH was that all bleedings were limited from "bridging veins" or "cortical veins." The prognosis of boxers was most closely correlated with the site of bleeding (r2 = 0.81; p = 0.0001) and the midline shift (r2 = 0.67; p = 0.007). Our study shows that ASDH because of boxing is characterized by bleeding from bridging or cortical veins, and that the site of bleeding is a significant determinant of their prognosis.

  13. Thought insertion as a self-disturbance: An integration of predictive coding and phenomenological approaches

    Directory of Open Access Journals (Sweden)

    Philipp Sterzer

    2016-10-01

    Full Text Available Current theories in the framework of hierarchical predictive coding propose that positive symptoms of schizophrenia, such as delusions and hallucinations, arise from an alteration in Bayesian inference, the term inference referring to a process by which learned predictions are used to infer probable causes of sensory data. However, for one particularly striking and frequent symptom of schizophrenia, thought insertion, no plausible account has been proposed in terms of the predictive-coding framework. Here we propose that thought insertion is due to an altered experience of thoughts as coming from nowhere, as is already indicated by the early 20th century phenomenological accounts by the early Heidelberg School of psychiatry. These accounts identified thought insertion as one of the self-disturbances (from German: Ichstörungen of schizophrenia and used mescaline as a model-psychosis in healthy individuals to explore the possible mechanisms. The early Heidelberg School (Gruhle, Mayer-Gross, Beringer first named and defined the self-disturbances, and proposed that thought insertion involves a disruption of the inner connectedness of thoughts and experiences, and a becoming sensory of those thoughts experienced as inserted. This account offers a novel way to integrate the phenomenology of thought insertion with the predictive coding framework. We argue that the altered experience of thoughts may be caused by a reduced precision of context-dependent predictions, relative to sensory precision. According to the principles of Bayesian inference, this reduced precision leads to increased prediction-error signals evoked by the neural activity that encodes thoughts. Thus, in analogy with the prediction-error related aberrant salience of external events that has been proposed previously, internal events such as thoughts (including volitions, emotions and memories can also be associated with increased prediction-error signaling and are thus imbued with

  14. Cover gas box for handling sodium

    Kuenstler, K.; Betzl, K.

    1978-01-01

    An inert atmosphere box has been developed to work with sodium experimentally and analytically. The volumen of the box is 0.6 m 3 . A blower mounted inside the work chamber constantly circulates the argon from the work chamber through a gas purification system (nickel-catalyst 6525 and molecular sieve 4A). The flow rate is 450 l/h. The box is equipped with neoprene gloves. The glove ports can be closed with interior flanges. The work chamber is constantly kept to a low superpressure of 25 mm water gange. In a bypass the oxygen concentration is measured with the OXYLYT-electrolyte cell and the water vapour concentration with the KEIDEL-electrolytic hygrometer. During long-term operation oxygen levels of 35 vpm and water vapour levels of 50 vpm can be hold even when the gloves are not covered. By means of putting a vessel with liquid sodium in the work chamber oxygen levels of 8 vpm and water vapour levels of 20 vpm can be attained for short times. The inert atmosphere purity can be improved by means of increasing the gas flow rate. (author)

  15. Thought waves remotely affect the performance (output voltage) of photoelectric cells

    Cao, Dayong; Cao, Daqing

    2012-02-01

    In our experiments, thought waves have been shown to be capable of changing (affecting) the output voltage of photovoltaic cells located from as far away as 1-3 meters. There are no wires between brain and photoelectric cell and so it is presumed only the thought waves act on the photoelectric cell. In continual rotations, the experiments tested different solar cells, measuring devices and lamps, and the experiments were done in different labs. The first experiment was conducted on Oct 2002. Tests are ongoing. Conclusions and assumptions include: 1) the slow thought wave has the energy of space-time as defined by C1.00007: The mass, energy, space and time systemic theory- MEST. Every process releases a field effect electrical vibration which be transmitted and focussed in particular paths; 2) the thought wave has the information of the order of tester; 3) the brain (with the physical system of MEST) and consciousness (with the spirit system of the mind, consciousness, emotion and desire-MECD) can produce the information (a part of them as the Genetic code); 4) through some algorithms such as ACO Ant Colony Optimization and EA Evolutionary Algorithm (or genetic algorithm) working in RAM, human can optimize the information. This Optimizational function is the intelligence; 5) In our experiments, not only can thought waves affect the voltage of the output photoelectric signals by its energy, but they can also selectively increase or decrease those photoelectric currents through remote consciousness interface and a conscious-brain information technology.

    The aim of this paper is to present Finnish employees' opinions on continuing work until retirement pension and after the age of 63, and to find out if physical workload is related to these opinions. Altogether 39% of men and 40% of women had never had thoughts of early retirement, and 59% claimed (both men and women) that they would consider working beyond the age of 63. Own health (20%); financial gain such as salary and better pension (19%); meaningful, interesting and challenging work (15%); flexible working hours or part-time work (13%); lighter work load (13%); good work community (8%); and good work environment (6%) were stated as factors affecting the decision to continue working after the age of 63. Employees whose work involved low physical workload had less thoughts of early retirement and had considered continuing work after the age of 63 more often than those whose work involved high physical loads. Own health in particular was stated as a reason to consider continuing work by employees whose work was physically demanding.

    Full Text Available Love is a basic subject of Islamic mysticism. It is apparently the hallmark of Eynolghozat's thought as well. Hence, Mystics pronounce him as "Sheikh-al-Asheghin", "Sultan-al-oshshagh", and so on. Eynalghozat considers love as a common faith between God, human beings, and the whole universe by which enmity changes to friendship. He also considers love as a perfect leader who guides the lovers through the way ending to the eminent God. In his opinion, Love which can never be spoken of except by symbolic language is of three main types Great Love, e, middle love, and lower love. Like other mystics figurative (platonic love id of considerable importance for him. However, the first and second types of love -mentioned above- are much more prevalent in his works. In this article, the writer tries to supply a brief definition of love in Eynolghozat's opinion, as well as a comparison of his thoughts with his master that is, Ahmad Ghazali.

    The Nominalists of the XIV century, precursors of modern science, thought that science's object was not the general, vague and indeterminate but the particular, which is real and can be known directly. About the middle of the XVII Century the bases of the modern science became established thanks to a revolution fomented essentially by Galileo, Bacon and Descartes. During the XVIII Century, parallel to the development of the great current of English Empiricism, a movement of scientific renewal also arose in continental Europe following the discipline of the Dutch Physicians and of Boerhaave. In the XIX Century, Claude Bernard dominated the scientific medicine but his rigorous determinism impeded him from taking into account the immense and unforeseeable field of the random. Nowadays, we approach natural science and medicine, from particular groups of facts; that is, from the responses of Nature to specific questions, but not from the general laws. Furthermore, in recent epistemology, the concept that experimental data are not pure facts, but rather, facts interpreted within a hermeneutical context has been established. Finally a general tendency to retrieve philosophical questions concerning the understanding of essence and existence can frequently be seen in scientific inquiry. In the light of the evolution of medical thought, it is possible to establish the position of scientific medicine within the movement of ideas dominating in our time.

    2016-04-01

    Chemical behavior in the environment is often modeled with multimedia fate models. SimpleBox is one often-used multimedia fate model, firstly developed in 1986. Since then, two updated versions were published. Based on recent scientific developments and experience with SimpleBox 3.0, a new version of SimpleBox was developed and is made public here: SimpleBox 4.0. In this new model, eight major changes were implemented: removal of the local scale and vegetation compartments, addition of lake compartments and deep ocean compartments (including the thermohaline circulation), implementation of intermittent rain instead of drizzle and of depth dependent soil concentrations, adjustment of the partitioning behavior for organic acids and bases as well as of the value for enthalpy of vaporization. In this paper, the effects of the model changes in SimpleBox 4.0 on the predicted steady-state concentrations of chemical substances were explored for different substance groups (neutral organic substances, acids, bases, metals) in a standard emission scenario. In general, the largest differences between the predicted concentrations in the new and the old model are caused by the implementation of layered ocean compartments. Undesirable high model complexity caused by vegetation compartments and a local scale were removed to enlarge the simplicity and user friendliness of the model. Copyright © 2016 Elsevier Ltd.

    To determine if 30 minutes of Nintendo Wii Sports boxing provides cardiorespiratory benefits and contributes to the daily exercise recommendations for healthy young adults. Twenty healthy 23- to 27-year-olds participated in two sessions to measure maximum heart rate (HR(max)) via a treadmill test and heart rate (HR) response to 30 minutes of Wii Sports boxing. Heart rate in beats per minute (bpm) was measured continuously, and exercise intensity during each minute of play was stratified as a percentage of HR(max). Mixed designs analysis of variance (ANOVA) and Pearson product moment correlations were used to analyze the data. Mean (SD) HR response to boxing was 143 (15) bpm or 77.5% (10.0%) of HR(max). The mean HR response for experienced participants was significantly lower than inexperienced participants, P = .007. The ANOVA revealed a significant interaction between experience and time spent at various intensities, P = .009. Experienced participants spent more time in light to vigorous intensities, inexperienced participants in moderate to very hard intensities. Fitness was not correlated with mean HR response to boxing, P = .49. Thirty minutes of Nintendo Wii Sports boxing provides a moderate to vigorous aerobic response in healthy young adults and can contribute to daily recommendations for physical activity.

  1. A New Chaotic System with Multiple Attractors: Dynamic Analysis, Circuit Realization and S-Box Design

    2017-12-01

    Full Text Available This paper reports about a novel three-dimensional chaotic system with three nonlinearities. The system has one stable equilibrium, two stable equilibria and one saddle node, two saddle foci and one saddle node for different parameters. One salient feature of this novel system is its multiple attractors caused by different initial values. With the change of parameters, the system experiences mono-stability, bi-stability, mono-periodicity, bi-periodicity, one strange attractor, and two coexisting strange attractors. The complex dynamic behaviors of the system are revealed by analyzing the corresponding equilibria and using the numerical simulation method. In addition, an electronic circuit is given for implementing the chaotic attractors of the system. Using the new chaotic system, an S-Box is developed for cryptographic operations. Moreover, we test the performance of this produced S-Box and compare it to the existing S-Box studies.

    Full Text Available Rationale and Objectives: Various devices are used to aid in the education of laparoscopic skills ranging from simple box trainers to sophisticated virtual reality trainers. Virtual reality system is an advanced and effective training method, however it is yet to be adopted in India due to its cost and the advanced technology required for it. Therefore, box trainers are being used to train laparoscopic skills. Hence this study was undertaken to assess the overall effectiveness of the box-training course. Study Procedure: The study was conducted during six-day laparoscopic skills training workshops held during 2006. Twenty five surgeons; age range of 26 to 45 years, of either sex, who had not performed laparoscopic surgery before; attending the workshop were evaluated. Each participant was given a list of tasks to perform before beginning the box-training course on day one and was evaluated quantitatively by rating the successful completion of each test. Evaluation began when the subject placed the first tool into the cannula and ended with task completion. Two evaluation methods used to score the subject, including a global rating scale and a task-specific checklist. After the subject completed all sessions of the workshop, they were asked to perform the same tasks and were evaluated in the same manner. For each task completed by the subjects, the difference in the scores between the second and first runs were calculated and interpreted as an improvement as a percentage of the initial score. Statistical Analysis: Wilcoxon matched-paired signed-ranks test was applied to find out the statistical significance of the results obtained. Results: The mean percentage improvement in scores for both the tasks, using global rating scale, was 44.5% + 6.930 (Mean + SD. For task 1, using the global rating scale mean percentage improvement was 49.4% + 7.948 (Mean + SD. For task 2, mean percentage improvement using global rating scale was 39.6% + 10.4 (Mean

  3. Prohibiting Headgear for Safety in Amateur Boxing? Opinion of the Canadian Boxing Community: an Online Poll.

    Science.gov (United States)

    Dickinson, Philip; Rempel, Philip

    In 2013, the Amateur International Boxing Association (AIBA) introduced a rule banning headgear for male-senior open class boxers during competition. The AIBA has defended the rule change as motivated by safety and supported by internal unpublished studies. As a result, in 2018, the AIBA plans to universally prohibit headgear in competition: for all competitors (male and female), all ages and all levels. Within Canada, this ruling has generated controversy in the boxing community, yet there has been no overall measure of opinion. To address this, we instituted a voluntary, anonymous, online open-access poll to allow members of the boxing community to express their stance on headgear use in competition. In total, 636 responses were received. A total of 71.5 % of Canadian respondents believed headgear should be mandatory at all levels. Only 5.8 % agreed that headgear should be prohibited, as planned for 2018. Estimating results on a representative breakdown of boxing membership in Canada, a similar pattern emerged, whereby 68.2 % concurred with mandatory headgear while only 4.95 % supported its prohibition. Parents of boxers were almost unanimously against banning headgear, stating they would change sports as a result. Similarly, only 1.7 % of women believed headgear should be prohibited. The consensus of the Canadian boxing community largely opposes the rule changes that the AIBA has implemented. The results highlight risks posed to the long-term viability of the sport, if significant grassroots safety concerns are disregarded.

    Thousands of boys and girls younger than 19 years participate in boxing in North America. Although boxing provides benefits for participants, including exercise, self-discipline, and self-confidence, the sport of boxing encourages and rewards deliberate blows to the head and face. Participants in boxing are at risk of head, face, and neck injuries, including chronic and even fatal neurologic injuries. Concussions are one of the most common injuries that occur with boxing. Because of the risk of head and facial injuries, the American Academy of Pediatrics and the Canadian Paediatric Society oppose boxing as a sport for children and adolescents. These organizations recommend that physicians vigorously oppose boxing in youth and encourage patients to participate in alternative sports in which intentional head blows are not central to the sport.

    2015-01-01

    This work presents an efficient implementation of the AES (Advance Encryption Standard) based on Tbox/T-1-box design for both the encryption and decryption on FPGA (Field Programmable Gate Array). The proposed architecture not only make efficient use of full capacity of dedicated 32 Kb BRAM (Block RAM) of latest Xilinx FPGAs (Virtex-5, Virtex-6 and 7 Series) but also saves considerable amount of BRAM and logical resources by using multiple accesses from single BRAM in one cycle of system clock as compared to conventional LUT (Look-Up-Table) techniques. The proposed T-box/T-1-box based AES design for both the encryption and decryption fits into just 4 BRAMs on FPGA and results in good efficiency TPS (Throughput per Slice) with less power consumption.

    DFBX distribution boxes provide cryogenic and electrical services to superconducting quadrupoles and to a superconducting dipole at either end of four of the long straight sections in the LHC. The DFBX boxes also provide instrumentation and quench protection to the magnets. Current for the quadrupole and the dipole magnet is delivered through leads that combine HTS and gas cooled leads. Current for the 600 A and 120 A correction magnets is provided by pure gas-cooled leads. The bus bars from the leads to the magnets pass through low leak-rate lambda plugs between 1.8 K and 4.4 K. The heat leak into the 1.9 K region from the liquid helium tank is determined by the design of the lambda plugs. This paper describes the DFBX boxes and their function of delivering current and instrumentation signals to the magnets

    This study utilizes a prospective design to examine the interaction of recent rape/attempted rape with individual differences in thought suppression on increases in disordered eating symptoms during late adolescence/emerging adulthood. Thought suppression is the attempt to suppress unwanted thoughts. We propose that emerging adult women who have experienced recent rape/attempted rape and tend to use thought suppression as a coping mechanism are at risk for increases in disordered eating. 319 women completed the Eating Disorder Examination Questionnaire, the Sexual Experiences Survey, the Childhood Trauma Questionnaire, and the White Bear Thought Suppression Inventory in their first month of college and three months later. The experience of recent rape/attempted rape in the three months prior to the assessment accounted for unique variance in disordered eating at Time 2. Levels of thought suppression assessed at Time 1 significantly moderated the influence of recent rape/attempted rape on disordered eating at Time 2.

    Full Text Available This paper provides an insight into an e-learning design approach that has been used by the author in a wide range of contexts in Higher Education as part of an ongoing enquiry into transforming online teaching and learning within sustainable 'real' courses. A key driver has been the need to engage learners in Higher Education in moving from consumers to producers of knowledge and to engage in communities of practice through the use of online tools for learning. These developments use an analytic framework to support thoughtful e-learning design and insights into the way his framework has been applied are presented through a number of case studies. This work is shaping Web2.0 technologies to match a learning rather than a social agenda by casting them in particular learning activities within specific contexts for particular learning purposes.Keywords: e-learning, activity theory

    This paper presents a real-time electro-encephalogram (EEG) identification system with the goal of achieving hands free control. With two EEG electrodes placed on the scalp of the user, EEG signals are amplified and digitised directly using a ProComp+ encoder and transferred to the host computer through the RS232 interface. Using a real-time multilayer neural network, the actual classification for the control of a powered wheelchair has a very fast response. It can detect changes in the user's thought pattern in 1 second. Using only two EEG electrodes at positions O(1) and C(4) the system can classify three mental commands (forward, left and right) with an accuracy of more than 79 %

    2004-06-01

    The cognitive bias of "Thought Action Fusion" (TAF) has received significant research attention in the past decade. The review addresses the assessment of TAF, its place in cognitive theories of obsessional difficulties, and the evidence demonstrating that TAF is relevant to disorders beyond Obsessive Compulsive Disorder (OCD). Data on the components of TAF, its extension to positive outcomes and its role in the aetiology, maintenance and treatment of OCD are reviewed. It is concluded that the moral form of TAF is less robust than the likelihood form and that scales may be best used as a starting point in identifying beliefs and conducting experimental investigations. It is also suggested that the scales be amended to include harm avoidance, which would also increase their clinical utility.

    The goal of this study was to investigate whether or not a brief educational intervention delivered prior to engaging in an anxiety-provoking task (writing a sentence about hoping that a friend/relative was in a car accident) would be effective in offsetting anxiety in college students with a strong propensity to endorse statements of thought action fusion (TAF). As hypothesized, individuals receiving the educational intervention were less anxious than a placebo intervention control group at post task; they were also less likely to endorse statements of TAF after receiving the educational intervention. Also, those who chose to neutralize after writing the sentence (regardless of experimental group) were more likely to report feeling guiltier, more immoral and a greater sense of responsibility about writing the sentence prior to neutralizing than those who did not subsequently neutralize. These results are discussed in relation to the cognitive theory of obsessive-compulsive disorder and implications for prevention programs.

    Full Text Available For more than 14 centuries, history has proved that Islamic teachings come with a variety of thoughts, social cultural backgrounds, periods through which the development and the dynamics evolved. The primary mission of mankind as the khalifah fil ardh (the caliph of the earth, is to practice the Islamic teachings (Shariah in accordance with the provisions of the primary source of Islam itself, i.e. the Qur’an and Hadith. At least, a long history of Islam as a religion of revelation suggests that the existence of Islamic teachings can grow and develop in every corner of the world, with a variety of spreading patterns that give the nuances and the mosaics in the development of the religion the present day.

  14. RETHINKING THE ANIMATE, RE-ANIMATING THOUGHT

    Directory of Open Access Journals (Sweden)

    Tim Ingold

    2013-12-01

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

  15. No Evidence for a Food-Related Attention Bias after Thought Suppression

    Barbara Soetens

    2008-01-01

    Full Text Available The aim of this study was to investigate whether food-related thought suppression results in an attention bias for food cues. Fifty-nine female students took part in the experiment. All completed a modified exogenous cueing task containing pictures of foods and toys with a similar valence (presentation duration: 250 ms and 1050 ms. Half of the participants were instructed to suppress thoughts about food and the other half was given control instructions, prior to completing the exogenous cueing task. No evidence was found for an enhanced cue validity effect for food cues after food-related thought suppression. Hence, the preliminary results do not provide support for the hypothesis that thought suppression is sufficient to yield an attention bias. Since the study was the first to employ an exogenous cueing task to study the attentional processing of food cues, replication is warranted.

    Full Text Available The work aims to describe and support, from the methodological point of view, Edgar Morin’s complex thought and Basarab Nicolescu’s transdisciplinarity. It is structured based on the philosophical and logical contexts of multi-method; and then developing methodological ideas from transdisciplinarity and complexity. The methodology used is the documentation, taking into account articles on doctrine and teaching experience. There is discourse analysis, classification and interpretation, also creating categories. The implications of integrative, complex and transdisciplinary philosophy are seen, in a research design for Social Sciences. Transdisciplinary category of "property" is provided, adding it to the "production" category. Developing the complexity and transdisciplinarity as a methodology, "transdisciplinary instructions" arise, which are applied to research although they were originally thought for teaching. From the structure of the research design, unsystematic transdisciplinary methodological strategies and systematic strategies element by element of the research project are identified. As another result, the creation of the category of "General Theory / Interim Science" is added, approached from transdisciplinarity

    Full Text Available Abstract Background Malaria vector sampling is the best method for understanding the vector dynamics and infectivity; thus, disease transmission seasonality can be established. There is a need to protecting humans involved in the sampling of disease vectors during surveillance or in control programmes. In this study, human landing catch, two cow odour baited resting boxes and an unbaited resting box were evaluated as vector sampling tools in an area with a high proportion of Anopheles arabiensis, as the major malaria vector. Methods Three resting boxes were evaluated against human landing catch. Two were baited with cow odour, while the third was unbaited. The inner parts of the boxes were covered with black cloth materials. Experiments were arranged in latin-square design. Boxes were set in the evening and left undisturbed; mosquitoes were collected at 06:00 am the next morning, while human landing catch was done overnight. Results A total of 9,558 An. arabiensis mosquitoes were collected. 17.5% (N = 1668 were collected in resting box baited with cow body odour, 42.5% (N = 4060 in resting box baited with cow urine, 15.1% (N = 1444 in unbaited resting box and 24.9% (N = 2386 were collected by human landing catch technique. In analysis, the house positions had no effect on the density of mosquitoes caught (DF = 3, F = 0.753, P = 0.387; the sampling technique had significant impact on the caught mosquitoes densities (DF = 3, F 37. 944, P Conclusion Odour-baited resting boxes have shown the possibility of replacing the existing traditional method (human landing catch for sampling malaria vectors in areas with a high proportion of An. arabiensis as malaria vectors. Further evaluations of fermented urine and longevity of the urine odour still need to be investigated.

    Kosiewicz Jerzy

    2018-03-01

    Full Text Available In the presented text the author points out to anthropological as well as axiological foundations of the boxing fight from the viewpoint of Hegel’s philosophy. In the genial idealist’s views it is possible to perceive the appreciation of the body, which constitutes a necessary basis for the man’s physical activity, for his work oriented towards the self-transformation and the transformation of the external world, as well as for rivalry and the hand-to-hand fight. While focusing our attention on the issue of rivalry and on the situation of the fight - and regarding it from the viewpoint of the master - slave theory (included in the phenomenology of spirit, it is possible to proclaim that even a conventionalised boxing fight - that is, restricted by cultural and sports rules of the game - has features of the fight to the death between two Hegelian forms of selfknowledge striving for self-affirmation and self-realisation. In the boxing fight, similarly as in the above mentioned Hegelian theory, a problem of work and of the development of the human individual (that is, of the subject, self-knowledge, the participant of the fight appears. There appears also a prospect of death as a possible end of merciless rivalry. The fight revalues the human way in an important way, whereas the prospect for death, the awareness of its proximity, the feeling that its close and possible, saturates the life with additional values. It places the boxer, just like every subject fighting in a similar or a different way, on the path towards absolute abstraction - that is, it brings him closer to his self-fulfilment in the Absolute, to the absolute synthesis. The Hegelian viewpoint enables also to appreciate the boxing fight as a manifestation of low culture (being in contrast with high culture, to turn attention to the relations which - according to Hegel - take place between the Absolute and the man, as well as to show which place is occupied by the subject both in

  20. Adaptation of Black-Box Software Components

    Directory of Open Access Journals (Sweden)

    Rolf Andreas Rasenack

    2008-01-01

    Full Text Available The globalization of the software market leads to crucial problems for software companies. More competition between software companies arises and leads to the force on companies to develop ever newer software products in ever shortened time interval. Therefore the time to market for software systems is shortened and obviously the product life cycle is shortened too. Thus software companies shortened the time interval for research and development. Due to the fact of competition between software companies software products have to develop low-priced and this leads to a smaller return on investment. A big challenge for software companies is the use of an effective research and development process to have these problems under control. A way to control these problems can be the reuse of existing software components and adapt those software components to new functionality or accommodate mismatched interfaces. Complete redevelopment of software products is more expensive and time consuming than to develop software components. The approach introduced here presents novel technique together with a supportive environment that enables developers to cope with the adaptability of black-box software components. A supportive environment will be designed that checks the compatibility of black-box software components with the assistance of their specifications. Generated adapter software components can take over the part of adaptation and advance the functionality. Besides, a pool of software components can be used to compose an application to satisfy customer needs. Certainly this pool of software components consists of black-box software components and adapter software components which can be connected on demand.

  1. Sodium bicarbonate ingestion and boxing performance.

    2010-01-01

    Boxing is a sport that consists of multiple high-intensity bouts separated by minimal recovery time and may benefit from a pre-exercise alkalotic state. The purpose of this study was to observe the ergogenic potential of sodium bicarbonate (NaHCO3) ingestion on boxing performance. Ten amateur boxers volunteered to participate in 2 competitive sparring bouts. The boxers were prematched for weight and boxing ability and consumed either 0.3 g.kg(-1) body weight (BW) of NaHCO3 (BICARB) or 0.045 g.kg(-1) BW of NaCl placebo (PLAC) mixed in diluted low calorie-flavored cordial. The sparring bouts consisted of four 3-minute rounds, each separated by 1-minute seated recovery. Blood acid-base (pH, bicarbonate [HCO3(-)], base excess [BE]), and performance (rates of perceived exertion [RPE], heart rate [HR] [HR(ave) and HR(max)], total punches landed successfully) profiles were analyzed before (where applicable) and after sparring. The results indicated a significant interaction effect for HCO3(-) (p < or = 0.001) and BE (p < 0.001), but not for pH (p = 0.48). Post hoc analysis revealed higher presparring HCO3(-) and BE for the BICARB condition, but no differences between the BICARB and PLAC conditions postsparring. There was a significant increase in punches landed during the BICARB condition (p < 0.001); however, no significant interaction effects for HRave (p = 0.15), HRmax (p = 0.32), or RPE (p = 0.38). The metabolic alkalosis induced by the NaHCO3 loading elevated before and after sparring blood buffering capacity. In practical application, the findings suggest that a standard NaHCO3 loading dose (0.3 g.kg(-1)) improves punch efficacy during 4 rounds of sparring performance.

    The paper presents a novel laboratory method for assessing boxing headguard impact performance. The method is applied to examine the effects of headguards on head impact dynamics and injury risk. A linear impactor was developed, and a range of impacts was delivered to an instrumented Hybrid III head and neck system both with and without an AIBA (Association Internationale de Boxe Amateur)-approved headguard. Impacts at selected speeds between 4.1 and 8.3 m/s were undertaken. The impactor mass was approximately 4 kg and an interface comprising a semirigid 'fist' with a glove was used. The peak contact forces were in the range 1.9-5.9 kN. Differences in head impact responses between the Top Ten AIBA-approved headguard and bare headform in the lateral and forehead tests were large and/or significant. In the 8.3 m/s fist-glove impacts, the mean peak resultant headform accelerations for bare headform tests was approximately 130 g compared with approximately 85 g in the forehead impacts. In the 6.85 m/s bare headform impacts, mean peak resultant angular head accelerations were in the range of 5200-5600 rad/s(2) and almost halved by the headguard. Linear and angular accelerations in 45° forehead and 60° jaw impacts were reduced by the headguard. The data support the opinion that current AIBA headguards can play an important role in reducing the risk of concussion and superficial injury in boxing competition and training.

    Full Text Available This study designed a radio-frequency identification (RFID-based Internet of Things (IoT platform to create the core of a smart nest box. At the sensing level, we have deployed RFID-based sensors and egg detection sensors. A low-frequency RFID reader is installed in the bottom of the nest box and a foot ring RFID tag is worn on the leg of individual hens. The RFID-based sensors detect when a hen enters or exits the nest box. The egg-detection sensors are implemented with a resistance strain gauge pressure sensor, which weights the egg in the egg-collection tube. Thus, the smart nest box makes it possible to analyze the laying performance and behavior of individual hens. An evaluative experiment was performed using an enriched cage, a smart nest box, web camera, and monitoring console. The hens were allowed 14 days to become accustomed to the experimental environment before monitoring began. The proposed IoT platform makes it possible to analyze the egg yield of individual hens in real time, thereby enabling the replacement of hens with egg yield below a pre-defined level in order to meet the overall target egg yield rate. The results of this experiment demonstrate the efficacy of the proposed RFID-based smart nest box in monitoring the egg yield and laying behavior of individual hens.

    Most of the problems arising in science and engineering are nonlinear. They are inherently difficult to solve. Traditional analytical approximations are valid only for weakly nonlinear problems, and often break down for problems with strong nonlinearity. This book presents the current theoretical developments and applications of Keller-Box method to nonlinear problems. The first half of the bookaddresses basic concepts to understand the theoretical framework for the method. In the second half of the book, the authorsgive a number of examples of coupled nonlinear problems that have been solved

    Blum, G S; Green, M

    1978-06-01

    The effects of mood upon imaginal thought were explored with a highly trained undergraduate female hypnotic subject. She was hypnotically programmed to experience free-floating anxiety or pleasure in varying degrees just before the exposure of combinations of three Blacky Pictures, and to produce dreamlike imagery in response to the Blacky stimuli while under sway of the mood. Data from 98 dream trials, separated by amnesia, indicated that the affective states clearly influenced imaginal processes. Blind ratings by a psychoanalyst showed anxiety moods to be more closely associated with primary-process features characteristic of nocturnal dreams, whereas pleasure had a relatively higher incidence of daydreamlike ratings. Empirical analysis of themes yielded significant relationships of anxiety to physical injury to the self and verbal aggression toward others; pleasure was associated with circular movements and overt sex themes.

  9. Deepwater Gulf of Mexico more profitable than previously thought

    Craig, M.J.K.; Hyde, S.T.

    1997-01-01

    Economic evaluations and recent experience show that the deepwater Gulf of Mexico (GOM) is much more profitable than previously thought. Four factors contributing to the changed viewpoint are: First, deepwater reservoirs have proved to have excellent productive capacity, distribution, and continuity when compared to correlative-age shelf deltaic sands. Second, improved technologies and lower perceived risks have lowered the cost of floating production systems (FPSs). Third, projects now get on-line quicker. Fourth, a collection of other important factors are: Reduced geologic risk and associated high success rates for deepwater GOM wells due primarily to improved seismic imaging and processing tools (3D, AVO, etc.); absence of any political risk in the deepwater GOM (common overseas, and very significant in some international areas); and positive impact of deepwater federal royalty relief. This article uses hypothetical reserve distributions and price forecasts to illustrate indicative economics of deepwater prospects. Economics of Shell Oil Co.'s three deepwater projects are also discussed

  10. Deflection monitoring for a box girder based on a modified conjugate beam method

    Chen, Shi-Zhi; Wu, Gang; Xing, Tuo

    2017-08-01

    After several years of operation, a box girder bridge would commonly experience excessive deflection, which endangers the bridge’s life span as well as the safety of vehicles travelling on it. In order to avoid potential risks, it is essential to constantly monitor the defection of box girders. However, currently, the direct deflection monitoring methods are limited by the complicated environments beneath the bridges, such as rivers or other traffic lanes, which severely impede the layouts of the sensors. The other indirect deflection monitoring methods mostly do not thoroughly consider the inherent shear lag effect and shear deformation in the box girder, resulting in a rather large error. Under these circumstances, a deflection monitoring method suiting box girders is proposed in this article, based on the conjugate beam method and distributed long-gauge fibre Bragg grating (FBG) sensor. A lab experiment was conducted to verify the reliability and feasibility of this method under practical application. Further, the serviceability under different span-depth ratios and web thicknesses was examined through a finite element model.

  11. Arrays of Cooper pair boxes coupled to a superconducting reservoir: 'superradiance' and 'revival'

    International Nuclear Information System (INIS)

    Rodrigues, D A; Gyoerffy, B L; Spiller, T P

    2004-01-01

    We consider an array of l b Cooper pair boxes, each of which is coupled to a superconducting reservoir by a capacitive tunnel junction. We discuss two effects that probe not just the quantum nature of the islands, but also of the superconducting reservoir coupled to them. These are analogues to the well-known quantum optical effects 'superradiance' and 'revival'. When revival is extended to multiple systems, we find that 'entanglement revival' can also be observed. In order to study the above effects, we utilize a highly simplified model for these systems in which all the single-electron energy eigenvalues are set to be the same (the strong coupling limit), as are the charging energies of the Cooper pair boxes, allowing the whole system to be represented by two coupled quantum spins, one finite, which represents the array of boxes, and one representing the reservoir, which we consider in the limit of infinite size. Although this simplification is drastic, the model retains the main features necessary to capture the phenomena of interest. Given the progress in superconducting box experiments over recent years, it is possible that experiments to investigate both of these interesting quantum coherent phenomena could be performed in the foreseeable future

  12. The effects of thoughts of survival and thoughts of death on recall in the adaptive memory paradigm.

    Klein, Stanley B

    2014-01-01

    In a recent paper Hart and Burns (2012) presented evidence that conditions that prime thoughts of one's mortality benefit recall. Drawing on the conceptual relation between thoughts of death and thoughts of survival, Hart and Burns interpret their findings as suggestive of the possibility that death-related thoughts function in manner similar to survival-related thoughts in enhancing recall. In the present study I draw on evolutionary arguments to question whether a conceptual relation between thoughts of death and thoughts of survival translates into a functional relation. I then present data showing that while death-related thoughts can promote high levels of recall, (a) the level achieved does not match that produced by survival processing and (b) survival and death cognition likely rely on different mechanisms to achieve their effects.

    We do a systematic study of the phases of gravity coupled to an electromagnetic field and charged scalar in flat space, with box boundary conditions. The scalar-less box has previously been investigated by Braden, Brown, Whiting and York (and others) before AdS/CFT and we elaborate and extend their results in a language more familiar from holography. The phase diagram of the system is analogous to that of AdS black holes, but we emphasize the differences and explain their origin. Once the scalar is added, we show that the system admits both boson stars as well as hairy black holes as solutions, providing yet another way to evade flat space no-hair theorems. Furthermore both these solutions can exist as stable phases in regions of the phase diagram. The final picture of the phases that emerges is strikingly similar to that found recently for holographic superconductors in global AdS, http://arxiv.org/abs/1602.07211. Our construction lays bare certain previously unnoticed subtleties associated to the definition quasi-local charges for gravitating scalar fields in finite regions.

    Glove boxes are used in the Transuranium Processing Plant (TRU) at Oak Ridge National Laboratory for (1) completing the final chemical processing steps to isolate and purify the transplutonium elements, (2) packaging transplutonium elements for shipment, (3) preirradiation and postirradiation processing of samples used to produce special transplutonium isotopes in the High Flux Isotope Reactor (HFIR), and (4) conducting special projects, which include providing highly purified transplutonium products in special chemical forms and/or in experimental devices as requested by researchers. During 20 years of operation, the quantities of transplutonium elements produced, and thus the amount of radioactivity handled, have continually increased. At the same time, substantial effort has been expended to reduce personnel radiation exposures. Equipment and techniques have been developed to maintain the desired operational capabilities in the glove boxes while keeping radiation exposures to operating personnel as low as reasonably achievable. Developments have included the design and fabrication of product handling and collection devices, product storage containers, and laminated exterior shields of lead glass, lead acrylic, acrylic sheets, polyethylene, and lead

    Boxing remains a subject of controversy and is often classified as dangerous. But the discussion is based mostly on retrospective studies. This survey was conducted as a prospective study. From October 2012 to September 2013, 44 competitive boxers were asked to report their injuries once a month. The questionnaire collected general information (training, competition) and recorded the number of bouts fought, injuries and resulting lost days. A total of 192 injuries were recorded, 133 of which resulted in interruption of training or competition. Each boxer sustained 3 injuries per year on average. The injury rate was 12.8 injuries per 1 000 h of training. Boxers fighting more than 3 bouts per year sustain more injuries (p=0.0075). The injury rate does is not a function of age (age≤19 vs. > 19a, p=0.53). Injuries to the head and the upper limbs occur most frequently. The most common injuries are soft tissue lacerations and contusions. Head injuries with neurological symptoms rarely occur (4.2%). Boxing has a high injury rate that is comparable with other contact sports, but most injuries are minor. Injury frequency is not a function of whether the boxer competes in the junior or adult category. Athletes fighting many bouts per year have a greater risk of injury. © Georg Thieme Verlag KG Stuttgart · New York.

  17. Some thoughts on psychoanalysis and ethics.

    Science.gov (United States)

    Szpilka, Jaime

    2002-10-01

    The author attempts to establish a framework for understanding the contribution of psychoanalysis to ethics through examining the work of certain philosophers, especially Kant. After reviewing the development of Freudian thought and going beyond the 'psychoanalysis and/or psychiatry?' question, he asserts that the space of the psychoanalytical cure revolves around an ethical problem. Thus, the limits of analysis should be determined by the subject's capacity for developing a structure of belief in the unconscious, with the concomitant capacity to go beyond equivocation in respect of an ethical conflict that underlies all cases where psychical suffering is manifested. Indeed, only human beings are called upon to deal with an ethical paradox-equally a logical one-which could be stated thus: there is Good in Evil and Evil in Good. This ethical paradox is the consequence of human subjection to the constituent laws of the Oedipus complex, which distances the human being, in his/her dealings with Evil and with Good, from any naturalist stance. In respect of the cure, then, we must take into account that Evil does not proceed from any particular drive-based characteristic, but is rather the expression of specific subjection to an unconscious Other, towards which it directs its affects. Finally, the author proposes a principle that emerges from the preceding discussion: let us not impute to or place in the Other our own subjective splitting or pain at existing.

  18. FROM MYTHICAL THINKING TO POLITICAL THOUGHT

    2015-10-01

    Full Text Available The article focuses on the Russian epos as well as Russian fairy tales: the images that are frequently there tend to be projected on the contemporary political discourse. The author assumes that the analysis of the folklore stories might allow defining the archetypes, which in a certain manner affect the contemporary political thought in Russia. The author demonstrates the way in which the national cultural archetypes relate to the common cultural ones (Greek myths, on the one hand, and, on the other hand, contain their specific national modification. Thus, the Hero Archetype in Russian epos appears to be nationally marked (its Russianness is particularly stressed as well as the image of an enemy, filling in the Shadow Archetype. Russian ‘bogatyr’ is traditionally on a state service and remains faithful to his grand duke, notwithstanding the injustice of the latter. The characters of fairy tales wage “preventive wars” in which they become the winners. The contemporary Russian political discourse inherits, to a certain extent, the value as well as the worldview aspects of the Russian epos.

    2017-06-01

    In this paper, the method to develop cryptographically strong substitution box is presented which can be used in multimedia security and data hiding techniques. The algorithm of construction depends on the action of a projective general linear group over the set of units of the finite commutative ring. The strength of substitution box and ability to create confusion is assessed with different available analyses. Moreover, the ability of resistance against malicious attacks is also evaluated. The substitution box is examined by bit independent criterion, strict avalanche criterion, nonlinearity test, linear approximation probability test and differential approximation probability test. This substitution box is equated with well-recognized substitution boxes such as AES, Gray, APA, S8, prime of residue, Xyi and Skipjack. The comparison shows encouraging results about the strength of the proposed box. The majority logic criterion is also calculated to analyze the strength and its practical implementation.

    The mental control of mood and mood-related thought was investigated. In Experiment 1, Ss reminiscing about a happy or sad event were asked to make their mood positive, were given no instructions, or were asked to make their mood negative. Ss attempting mood control without an imposed cognitive load were successful, whereas those who attempted control while rehearsing a 9-digit number not only failed to control their moods but also showed self-reported mood change opposite the mood they intended to create. In Experiment 2, Ss attempting to control mood-related thoughts under cognitive load showed increased accessibility of those thoughts contrary to the direction of intended control in a Stroop-type color-naming task.

    We study a model for the hydrogen atom confined within spherical boxes with penetrable walls. The potential consists of the Coulomb potential inside the box and a constant potential outside the box; the Schroedinger equation admits analytical solutions in both regions. The energy eigenvalues and eigenfunctions for the lowest states of the system are determined numerically for boxes of different sizes and penetrabilities. In addition, we also evaluate the hyperfine splitting, nuclear magnetic shielding, polarizability and pressure of the system and investigate the effect of the confinement on these atomic properties

The method is based on chaotic maps and simulated annealing. In addition, cryptographic properties such as bijectivity, strict avalanche criterion, nonlinearity, output bits independence criterion and equiprobable input/output XOR distribution are analyzed in detail for the S-box produced. The results of numerical analysis show that the box has nearly fulfilled the criteria for a cryptographically strong S-box and can effectively resist several attacks

    Science.gov (United States)

    Nelson, Andrea L; Purdon, Christine

    2011-04-01

    According to Barlow's model of sexual dysfunction, anxiety in sexual situations leads to attentional focus on sexual performance at the expense of erotic cues, which compromises sexual arousal. This negative experience will enhance anxiety in future sexual situations, and non-erotic thoughts (NETs) relevant to performance will receive attentional priority. Previous research with student samples (Purdon & Holdaway, 2006; Purdon & Watson, 2010) has found that people experience many types of NETs in addition to performance-relevant thoughts, and that, consistent with Barlow's model, the frequency of and anxiety evoked by these thoughts is positively associated with sexual problems. Extending this previous work, the current study found that, in a community sample of women (N = 81) and men (N = 72) in long-term relationships, women were more likely to report body image concerns and external consequences of the sexual activity, while men were more likely to report performance-related concerns. Equally likely among men and women were thoughts about emotional consequences of the sexual activity. Regardless of thought content, experiencing more frequent NETs was associated with more sexual problems in both women and men. Moreover, as per Barlow's model, greater negative affect in anticipation of and during sexual activity predicted greater frequency of NETs and greater anxiety in response to NETs was associated with greater difficulty dismissing the thoughts. However, greater difficulty in refocusing on erotic thoughts during sexual activity uniquely predicted more sexual problems above the frequency and dismissability of NETs. Together, these data support the cognitive interference mechanism implicated by Barlow's causal model of sexual dysfunction and have implications for the treatment of sexual problems.

  10. The merits of unconscious thought in rule detection.

    Li, Jiansheng; Zhu, Yawen; Yang, Yang

    2014-01-01

    According to unconscious thought theory (UTT), unconscious thought is more adept at complex decision-making than is conscious thought. Related research has mainly focused on the complexity of decision-making tasks as determined by the amount of information provided. However, the complexity of the rules generating this information also influences decision making. Therefore, we examined whether unconscious thought facilitates the detection of rules during a complex decision-making task. Participants were presented with two types of letter strings. One type matched a grammatical rule, while the other did not. Participants were then divided into three groups according to whether they made decisions using conscious thought, unconscious thought, or immediate decision. The results demonstrated that the unconscious thought group was more accurate in identifying letter strings that conformed to the grammatical rule than were the conscious thought and immediate decision groups. Moreover, performance of the conscious thought and immediate decision groups was similar. We conclude that unconscious thought facilitates the detection of complex rules, which is consistent with UTT.

    Full Text Available A number of recent studies have reported that decision-quality is enhanced under conditions of inattention or distraction (unconscious-thought; Dijksterhuis, 2004; Dijksterhuis et al., 2006; Dijksterhuis & Nordgren, 2006. These reports have generated considerable controversy, for both experimental (problems of replication and theoretical reasons (interpretation. Here we report the results of four experiments. The first experiment replicates the unconscious thought effect, under conditions that validate and control the subjective criterion of decision quality. The second and third experiments examine the impact of a mode of thought manipulation (without distraction on decision quality in immediate decisions. Here we find that intuitive or affective manipulations improve decision quality compared to analytic/deliberation manipulations. The fourth experiment combines the two methods (distraction and mode of thought manipulations and demonstrates enhanced decision quality, in a situation that attempts to preserve ecological validity. The results are interpreted within a framework that is based on two interacting subsystems of decision-making: an affective/intuition based system and an analytic/deliberation system.

    Pornography is one of the most sought-after topics on the Internet, and is easily available for anyone, including children and adolescents. At youth centres, nurse-midwives have noticed that young people have different kinds of questions about sexual practices compared with a few years ago. The aim of this study was to gain an understanding of thoughts and reflections about pornography consumption, and its possible influence on sexual practices, among young women and men. The staff at a youth centre in a city in central Sweden asked the visitors if they had seen pornography and if they wanted to be interviewed about their experiences. Ten young women and eight men, aged 16-23 years, participated. In-depth interviews were performed and open-ended questions about pornography and sexuality were posed. The interviews were tape-recorded and transcribed verbatim. Data were analysed according to grounded theory. The core category 'Living with the current sexual norm' depicted how pornography created sexual expectations and demands, for instance, to perform certain sexual acts. The informants expressed contradictory feelings towards pornography and felt that sexuality was separated from intimacy. A moral attitude was described and examples of stereotypic gender roles were given. To deal with the current sexual norm, informants had different individual handling strategies and attitudes to pornography, namely liberal, normalization, distance, feminist or conservative. Limitations of this study were the small sample size and that results from a qualitative research study cannot be generalized. The results contribute to an understanding of how pornographic material can influence young peoples' thoughts, reflections and sexual behaviour. This indicates the importance, for personnel at youth centres and schools, to discuss sexual behaviour and how sexuality is portrayed in pornographic material with young people.

    For nearly 50 years, psychologists have studied prospective memory, or the ability to execute delayed intentions. Yet, there remains a gap in understanding as to whether initial encoding of the intention must be elaborative and strategic, or whether some components of successful encoding can occur in a perfunctory, transient manner. In eight studies (N = 680), we instructed participants to remember to press the Q key if they saw words representing fruits (cue) during an ongoing lexical decision task. They then typed what they were thinking and responded whether they encoded fruits as a general category, as specific exemplars, or hardly thought about it at all. Consistent with the perfunctory view, participants often reported mind wandering (42.9%) and hardly thinking about the prospective memory task (22.5%). Even though participants were given a general category cue, many participants generated specific category exemplars (34.5%). Bayesian analyses of encoding durations indicated that specific exemplars came to mind in a perfunctory manner rather than via strategic, elaborative mechanisms. Few participants correctly guessed the research hypotheses and changing from fruit category cues to initial-letter cues eliminated reports of specific exemplar generation, thereby arguing against demand characteristics in the thought probe procedure. In a final experiment, encoding duration was unrelated to prospective memory performance; however, specific-exemplar encoders outperformed general-category encoders with no ongoing task monitoring costs. Our findings reveal substantial variability in intention encoding, and demonstrate that some components of prospective memory encoding can be done “in passing.” PMID:29874277

    This research is done by comparing PCI and Box Girder types of prestressed concrete design. The method used is load balance. Previous studies have just discussed the differences in terms of effectiveness and economics. In this study, the researchers want to know the design process by comparing the working forces, the resulting moment, and the losses of the prestressed. As the case in this study, the researchers used the bridge with the span of 31 meters. The tendon pulling system was conducted with post-tensioning system The analysis result showed that prestressed of the Girder box type sustained the greatest moment due to the combination of its own weight, additional dead load, lane load, and wind load of 44,029 kNm, while the biggest moment of PCI Girder was 7,556.75 KNm The Girder beam box experiences greater moment and shear force than PCI Girder. This is the effect of the weight of its own Girderboxwaslarger than PCI Girder. The losses ofprestressed style of Girderboxand PCI Girder type were 24.85% and 26.32%, respectively.Moreover, it showed that the type of Girder box is cheaper, easier, and more efficient than PCI Girder.

    Methods of analysis that include an assessment of opponent interactions are thought to provide a more valid means of team match performance. The purpose of this study was to examine the effect of playing tactics on achieving score-box possession by assessing opponent interactions in Norwegian elite soccer matches. We analysed a random series of 1703 team possessions from 163 of 182 (90%) matches played in the professional men's league during the 2004 season. Multidimensional qualitative data obtained from ten ordered categorical variables were used. Offensive tactics were more effective in producing score-box possessions when playing against an imbalanced defence (28.5%) than against a balanced defence (6.5%) (P tactics on producing score-box possessions, and improves the validity of team match-performance analysis in soccer.

    TORCH is a large-area precision time-of-flight detector based on the DIRC principle. The DIRC bar boxes of the BaBar experiment at SLAC could possibly be reused to form a part of the TORCH detector time-of-flight wall area, proposed to provide positive particle identification of low momentum kaons in the LHCb experiment at CERN. For a potential integration of BaBar bar boxes into TORCH, new imaging readout optics are required. From the several designs of readout optics that have been considered, two are used in this paper to study the effect of BaBar bar optical imperfections on the detector reconstruction performance. The kaon-pion separation powers obtained from analysing simulated photon hit patterns show the performance reduction for a BaBar bar of non-square geometry compared to a perfectly rectangular cross section.

    Traditional computer videogames are sedentary, whereas new computer videogames, such as the Nintendo(®) (Redmond, WA) "Wii™ Sports" games, allow users to physically interact while playing the sport. Energy expenditure (EE), heart rate (HR), and rating of perceived exertion (RPE) during heavy bag boxing versus the Nintendo "Wii Boxing" game were compared. Fifteen males and 14 females (mean age, 25.6 years; height, 171.3 cm; weight, 71.8 kg) randomly selected (by a coin toss) heavy bag boxing or "Wii Boxing" for their first test session and completed the other protocol at their second session at least 2 days later. Each session lasted for a total duration of 30 minutes and consisted of 10 3-minute exercise bouts with measurements of HR, RPE, and EE obtained from indirect calorimetry. A paired-samples t test was used to analyze the results. Significant differences were found for HR (bag, 156 beats per minute; Wii, 138 beats per minute; P=0.001) and RPE (bag, 13.8; Wii, 11.4; P=0.0001) but not for EE (bag, 8.0 kcal/minute; Wii, 7.1 kcal/minute; bag, 241 total kcal; Wii, 213 total kcal; P=0.078). The results suggest that computer active videogames, such as the Nintendo Wii, have the potential to provide similar EE as their traditional forms of exercise and may be a sufficient replacement for traditional target HR zone activities, especially in less fit individuals. Further research is needed to compare EE for different "Wii Sports" games with those for their traditional forms of exercise.

    Five experiments examined effects of songs with violent lyrics on aggressive thoughts and hostile feelings. Experiments 1, 3, 4 and 5 demonstrated that college students who heard a violent song felt more hostile than those who heard a similar but nonviolent song. Experiments 2-5 demonstrated a similar increase in aggressive thoughts. These effects replicated across songs and song types (e.g., rock, humorous, nonhumorous). Experiments 3-5 also demonstrated that trait hostility was positively related to state hostility but did not moderate the song lyric effects. Discussion centers on the potential role of lyric content on aggression in short-term settings, relation to catharsis and other media violence domains, development of aggressive personality, differences between long-term and short-term effects, and possible mitigating factors.

    Full Text Available Lightweight cryptographic solutions are required to guarantee the security of Internet of Things (IoT pervasiveness. Cryptographic primitives mandate a non-linear operation. The design of a lightweight, secure, non-linear 4 × 4 substitution box (S-box suited to Internet of Things (IoT applications is proposed in this work. The structure of the 4 × 4 S-box is devised in the finite fields GF (24 and GF ((222. The finite field S-box is realized by multiplicative inversion followed by an affine transformation. The multiplicative inverse architecture employs Euclidean algorithm for inversion in the composite field GF ((222. The affine transformation is carried out in the field GF (24. The isomorphic mapping between the fields GF (24 and GF ((222 is based on the primitive element in the higher order field GF (24. The recommended finite field S-box architecture is combinational and enables sub-pipelining. The linear and differential cryptanalysis validates that the proposed S-box is within the maximal security bound. It is observed that there is 86.5% lesser gate count for the realization of sub field operations in the composite field GF ((222 compared to the GF (24 field. In the PRESENT lightweight cipher structure with the basic loop architecture, the proposed S-box demonstrates 5% reduction in the gate equivalent area over the look-up-table-based S-box with TSMC 180 nm technology.

    This report describes the work performed in the frame of two C.E.C. - Contracts FI1D-002400-B Decommissioning of very large glove boxes and FI1D-0058 Decommissioning of a complex glove box structure to be dismounted partially on place. Detailed information is given about each glove box. The selection of the solution Transportation of the glove boxes to a specialized dismantling plant is justified. The necessary contacts inside the BELGONUCLEAIRE MOX plant and between the latter and other organizations are explained. The problems of manipulating large gloves are listed and the retained solution of building a so called Stiffening frame around each glove box is described. Furthermore information is given concerning required operators time for cleaning, manipulating, packing and dismantling together with received doses and quantities of waste produced. Concerning the glove box unit partially to be dismounted on place, detailed information is given about the way the glove boxes have been treated prior to this partial dismantling on place and about the way this partial dismantling has been performed. From these results one can conclude that such a delicate task can be performed without major difficulties. Finally information is given of the decontamination test of a highly Pu contaminated glove box with freon with rather poor results and of the preliminary CO 2 blasting tests on non active samples
