  2. Venice: a meeting, a plague, a death

    Directory of Open Access Journals (Sweden)

    Óscar Botasso

    2008-10-01

    Full Text Available Death in Venice is based on the novella of the same name by Thomas Mann, except that in the cinema version the main character, Gustav von Aschenbach, is a musician instead of a writer. Owing to poetic license not always within the layman’s grasp, Luchino Visconti also wished to identify the artist with Gustav Mahler. Beyond such dissimilarities, however, the film is a feasible recreation of the story and a faithful reconstruction of those times: a Venice divorced from its former splendor and invaded by a plague and yet at the same time still able to evoke the captivating, nostalgic legacy of its magnificent past. An ideal scenario indeed for the musical ideas of Mahler, and perfectly reflected in the Midnight Song and the adagietto of his third and fifth symphonies.

    The synchronous, electric micromotor of a time commutator, by means of a three staged cylindrical gear drive rotates a disk with a semirounded segmented notch, which, in turn, drives a Maltese cross. The gear drum, linked with the Maltese cross rotates a disk with an indicator, equipped with radial, spherical grooves, equidistant from each other. Radially projecting catches, which are used with rotation of the disk to accomplish elastic movement of a vertical shaft under the effect of a three beam, asymmetrical star, are mounted in the disk's grooves by means of spring loaded locking devices, in accordance with the required time technological program. There are driving and locking cams located on the lower end of the shaft. The first is of pear shaped section and provides drive to the microswitch, which commutates the output electrical circuit of the apparatus.

    Leslie Orgel and Francis Crick with Gobind Khorana in Madison, Wisconsin (December 1965). I first met Leslie at the Endicott House (MIT) in February 1964. Leslie was then spending a period of time at MIT and the occasion was a party for him. During our conversation, Leslie talked about starting some experimental work. He seemed to be particularly interested in polyphosphates and the chemical activation of small molecules (building blocks). Shortly after his move to the Salk Institute in the Fall of 1964 I visited him in January 1965. He already had a lab going. I remember meeting Jim Ferris, in particular, and John Sulston sometime later. That particular time was exciting for my research as well. We had the first results on the Genetic Code using the chemical-biochemical approach that my lab had developed. Francis Crick was also at the Salk Institute during the time of my visit. Both Leslie and Francis were very excited by my results and they began to ask a lot of questions and gave me a whole lot of suggestions about further experiments. In fact, my thinking and planning of things that we were doing were so scrutinized and clarified during these discussions that, it seemed to me, my own group had only to turn out all the experiments that were needed. These interactions with Francis and Leslie continued intensively throughout that year and later. In fact, both Leslie and Francis accepted my invitation to Madison in December 1965 for more discussions. Since those early days of the Salk Institute, I have made numerous visits over the years to Leslie and his research group. It has always been very exciting to learn about the many discoveries bearing on chemical evolution that have unfolded from Leslie's research group. In addition, I have always benefitted from the insightful comments that Leslie invariably provided on my own research. I look forward to our continued interactions and friendship in the future. Leslie, A Happy Birthday!

    Renowned astrophysicist Prof. Bhaskar Datta passed away in Bangalore on December 3rd, 1999 after a brave battle with cancer. He was 50. In his career spanning more than 25 years he worked extensively in the area of High-energy astrophysics, Astro-particle physics, General relativity and Cosmology. In particular, he specialized in the structure and properties of neutron stars. Prof. Datta was born and educated in Delhi. After obtaining his Master's degree in Physics from the Delhi University he worked in NORDITA, Copenhagen as a Guest Physicist. The following year he moved to the NASA Goddard Institute of Space Studies, New York, where he worked with Prof. V. Canuto for his Ph.D. thesis. He obtained his Ph.D. from City University of New York in 1977 for his work on spin-2 interaction in a relativistic neutron gas. He derived an equation of state of matter at high density using this interaction and demonstrated its effect on the derived masses and moments of inertia of neutron stars. Many years later he and his colleagues were to derive yet another Equation of State for neutron star matter, based on the chiral sigma model that includes a dynamically generated isoscalar vector field. Prof. Datta returned to India in 1978 after brief stays at University of Florida and International Centre for Theoretical Physics, Trieste, Italy. From 1978 to 1982 he worked at the Tata Institute of Fundamental Research, Mumbai. In 1982 he moved to the Indian Institute of Astrophysics, Bangalore where he worked until his death. He also held the position of an adjunct professorship at the Raman Research Institute, Bangalore. Prof. Datta's move to Bangalore coincided with the discovery of the fastest spinning neutron star known, namely the millisecond pulsar PSR 1937+21. By then already a recognised expert on neutron star structure, he plunged headlong into computing the structure with fast rotation. He, with his colleague Alak Ray, showed that the millisecond pulsar could be spinning

Selection of miRNAs associated with the formation and development of malignant tumors in the kidney was performed using computer databases miRWalk (http://www.ma.uni-hei-delberg.de/apps/zmf/mirwalk/ and miRBase (http://www.mir-base.org/. Paired samples of tumor and histologically normal tissue from 46 patients with RCC were studied. RNA was isolated by phenol–chloroform extraction and treated with RNase-free DNase after isolation. MiRNA expression analysis was performed by RT-qPCR using Applied Biosystems (USA kits: TaqMan® MicroRNA Assays, TaqMan® MicroRNA Reverse Transcription Kit, TaqMan® Fast Universal PCR Master Mix (2x. RNU6B was used as reference miRNA. Quantity alterations of 20 microRNAs (hsa-miR-219, -203, -148a, -129, -9, -34a, -34b, -34c-3p, -127, -193a-5p, -191, -17, -24 -2*, -339 -3p, -212, -375, -125b, -124a, -132, -137 were determined in samples of tumor compared to normal tissue biopsy from the kidney of each patient. It was shown that the expression of studied miRNAs usually decreased in RCC tumors. The largest decrease of expression was observed for miR-129, which expression was10–350-fold reduced in 93% of the samples (P < 0.05 with no change of expression in the remaining 7% of cases. MiR-375 (80% of cases,10–270-fold decrease, miR-34b (79% of cases, 10–60-fold decrease, miR-124a (70% of cases, 10–200-fold decrease also frequently showed reduced expression in tumors. In addition to the aforementioned ones, it had been shown that expression in the tumor compared with histologically normal tissue from the same patient was significantly decreased in more than half of the cases for miR-125b, miR-127, miR-203, miR-34c-3p, miR-9. Despite the fact that in 50% of cases

    Recent, unusual X-ray observations from our galactic neighbor, the Small Magellanic Cloud, have led to an interesting model for SXP 214, a pulsar in a binary star system.Artists illustration of the magnetic field lines of a pulsar, a highly magnetized, rotating neutron star. [NASA]An Intriguing BinaryAn X-ray pulsar is a magnetized, rotating neutron star in a binary system with a stellar companion. Material is fed from the companion onto the neutron star, channeled by the objects magnetic fields onto a hotspot thats millions of degrees. This hotspot rotating past our line of sight is what produces the pulsations that we observe from X-ray pulsars.Located in the Small Magellanic Cloud, SXP 214 is a transient X-ray pulsar in a binary with a Be-type star. This star is spinning so quickly that material is thrown off of it to form a circumstellar disk.Recently, a team of authors led by JaeSub Hong (Harvard-Smithsonian Center for Astrophysics) have presented new Chandra X-ray observations of SXP 214, tracking it for 50 ks (~14 hours) in January 2013. These observations reveal some very unexpected behavior for this pulsar.X-ray PuzzleThe energy distribution of the X-ray emission from SXP 214 over time. Dark shades or blue colors indicate high counts, and light shades or yellow colors indicate low counts. Lower-energy X-ray emission appeared only later, after about 20 ks. [Hong et al. 2016]Three interesting pieces of information came from the Chandra observations:SXP 214s rotation period was measured to be 211.5 s an increase in the spin rate since the discovery measurement of a 214-second period. Pulsars usually spin down as they lose angular momentum over time so what caused this one to spin up?Its overall X-ray luminosity steadily increased over the 50 ks of observations.Its spectrum became gradually softer (lower energy) over time; in the first 20 ks, the spectrum only consisted of hard X-ray photons above 3 keV, but after 20 ks, softer X-ray photons below 2 ke

    Full Text Available The photographic paradox is said to be that of a message without a code, a communication lacking a relay or gap essential to the process of communication. Tracing the recurrence of Barthes's definition in the essays included in Image/Music/Text and in La Chambre claire , this paper argues that Barthes's definition is platonic in its will to dematerialize the troubling — graphic — immediacy of the photograph. He writes of the image in order to flee its signature. As a function of media, his categories are written in order to be insufficient and inadequate; to maintain an ineluctable difference between language heard and letters seen; to protect an idiom of loss which the photograph disallows. The article studies the strategies of his definition in «The Photographic Paradox» as instrument of abstraction, opposes the notion of code, in an aural sense, to audio-visual markers of closed relay in advertising, and critiques the layout and order of La Chambre claire in respect to Barthes's ideology of absence.

    Full Text Available Marcada por produções freudianas, a literatura analítica e, mais especificamente, aquela influenciada pelo ensino lacaniano, não pára de mostrar que as considerações anatômicas não são índices para falar da diferença de identidade sexual entre homens e mulheres. Diante do fato de que características masculinas continuavam presentes em mulheres adultas normais, Freud responde que ser mulher é ser mãe. A vacilação da verdade desta equação pode ser observada nas situações mais diversas nas quais podemos nos defrontar com mulheres, mães, desempenhando papéis de homens. Como pensar esta constatação? Este trabalho permitir-nos-á mostrar a imbricação do feminino e do masculino num caso de uma mulher com todas as características de uma feminilidade considerada normal, e também discutir a questão do gozo fálico e do Outro gozo - propostos por Lacan como índices de diferenciação da posição masculina e da feminina.

    Full Text Available Tetrabromobisphenol A (TBBPA, a brominated flame retardant, has been found to exacerbate pneumonia in respiratory syncytial virus- (RSV- infected mice. We examined the effect of Brazilian propolis (AF-08 on the exacerbation of RSV infection by TBBPA exposure in mice. Mice were fed a powdered diet mixed with 1% TBBPA alone, 0.02% AF-08 alone, or 1% TBBPA and 0.02% AF-08 for four weeks and then intranasally infected with RSV. TBBPA exposure increased the pulmonary virus titer and level of IFN-γ, a representative marker of pneumonia due to RSV infection, in the lungs of infected mice without toxicity. AF-08 was significantly effective in reducing the virus titers and IFN-γ level increased by TBBPA exposure. Also, AF-08 significantly reduced proinflammatory cytokine (TNF-α and IL-6 levels in the lungs of RSV-infected mice with TBBPA exposure, but Th2 cytokine (IL-4 and IL-10 levels were not evidently increased. Neither TBBPA exposure nor AF-08 treatment affected the anti-RSV antibody production in RSV-infected mice. In flow cytometry analysis, AF-08 seemed to be effective in reducing the ratio of pulmonary CD8a+ cells in RSV-infected mice with TBBPA exposure. TBBPA and AF-08 did not exhibit anti-RSV activity in vitro. Thus, AF-08 probably ameliorated pneumonia exacerbated by TBBPA exposure in RSV-infected mice by limiting excess cellular immune responses.

    "No man is an Iland, intire of it selfe.". These words were written by John Donne, the Dean of St. Paul's, and appear as his 17th Meditation in "Devotions upon emergent Occasions and several steps in my Sickness," published in 1624, a work in which he reflects upon his life in the midst of a serious illness (most likely typhus). Like many literary works, the words are timeless, and their meaning is not constrained to the occasion of their birth. Donne's meditation is easily transferred to the person who was, is, or will be, editor of this or any journal. No editor is an island. No editor can honestly claim to be "intire of it selfe." The Editor of the Journal rides on the tide generated by his staff, his reviewers, and his readers. I have been blessed with a marvelous staff, enormously energetic and dedicated. They have always been willing to go the last mile--and more if need be. Most--but not all--came to the Journal soon after it arrived in Austin. The bedrock on which the Journal has been built is its numerous reviewers, too many to thank individually on this page, but appreciated nonetheless for their individual contributions. Reviewers define the quality of a journal, and we have had a superb cohort working for us--voluntarily. I have to apologize publicly to some (you know who you are) who were abused by repeated requests on a short time base for their comments on manuscripts. This condition, which occurred more often than I would have liked, arose from the idiosyncratic confluence of manuscript flow, momentarily popular topics, and the need for certain kinds of expertise. I know that multiple requests for comments came too rapidly in some cases, but it was of paramount importance to get "good reviews" whom I could trust, and I knew where to turn. Thanks to all of you who stepped forward in such circumstances, with grace and good humor, to produce the quality reviews that were so valuable to me. No editor is an "Iland, intire of it selfe," especially when it

    Marie-Françoise Collière (1930-2005) was a great lady of the nursing profession recognized worldwide for her expertise. As a historian, a pioneer and an activist of the cause of the female nurses and health care, she devoted her life to giving the profession the first meaning of care, ie: accompanying the patient through his life, from the birth to the death, through disease, accident and ageing. Thus, for Marie-Françoise Collière, "Caring means health-care through the satisfaction of a series of needs which are indispensable for life but which have diverse manifestations". Here is the story of her life and her trajectory.

    [figure removed for brevity, see original site] Click on the image for A Whale of a Panorama (QTVR) More than 1.5 years into their exploration of Mars, both of NASA's Mars Exploration Rovers continue to send a cornucopia of images to Earth. The results are so spectacular that Deputy Project Manager John Callas recently described them as 'an embarrassment of riches.' Spirit produced this image mosaic, nicknamed the 'Whale Panorama,' two-thirds of the way to the summit of 'Husband Hill,' where the rover investigated martian rocks. On the right side of the panorama is a tilted layer of rocks dubbed 'Larry's Outcrop,' one of several tilted outcrops that scientists examined in April, 2005. They used spatial information to create geologic maps showing the compass orientation and degree of tilting of rock formations in the vicinity. Such information is key to geologic fieldwork because it helps establish if rock layers have been warped since they formed. In this case, scientists have also been studying the mineral and chemical differences, which show that some rocks have been more highly altered than others. In the foreground, in the middle of the image mosaic, Spirit is shown with the scientific instruments at the end of its robotic arm positioned on a rock target known as 'Ahab.' The rover was busy collecting elemental chemistry and mineralogy data on the rock at the same time that it was taking 50 individual snapshots with its five panoramic camera filters to create this stunning view of the martian scenery. The twin tracks of the rover's all-terrain wheels are clearly visible on the left. This mosaic of images spans about 220 degrees from left to right and is an approximate true-color rendering of the Mars terrain acquired through the panoramic camera's 750-, 530-, and 430-nanometer filters. Spirit collected these images from its 497th martian day, or sol, through its 500th sol (May 27 through May 30, 2005).

    Full Text Available In this paper a population based evolutionary optimization methodology called firefly algorithm (FFA is applied for the optimization of system coefficients of the infinite impulse response (IIR system identification problem. FFA is inspired by the flash pattern and characteristics of fireflies. In FFA technique, behaviour of flashing firefly towards its competent mate is structured. In this algorithm attractiveness depends on brightness of light and a bright firefly feels more attraction for the brighter one. For this optimization problem, brightness varies inversely proportional to the error fitness value, so the position of the brightest firefly gives the optimum result corresponding to the least error fitness in multidimensional search space. Incorporation of different control parameters in basic movement equation results in balancing of exploration and exploitation of search space. The proposed FFA based system identification approach has alleviated from inherent drawbacks of premature convergence and stagnation, unlike genetic algorithm (GA, particle swarm optimization (PSO and differential evolution (DE. The simulation results obtained for some well known benchmark examples justify the efficacy of the proposed system identification approach using FFA over GA, PSO and DE in terms of convergence speed, identifying plant coefficients and mean square error (MSE fitness values produced for both same order and reduced order models of adaptive IIR filters.

    Full Text Available Let me begin by thanking everyone who commented on my ASA paper, "Toward a Praxis of World Integration," both those who were generally sympathetic to its thesis and those who were not. It is inconceivable to me that any two freethinking human beings living in our time could share the same preferred model of the good society. So of course I am not surprised that no one found every aspect of my vision appealing or that some found almost nothing to applaud. I would probably react to each of your utopias in muchthe same ways. Nonetheless, our species needs, perhaps more than anything else, to think together about where we want to go, and how, and why. Without tclos, how can we speak of praxis? And without praxis, what use is analysis? The point is to change the world and change it for the better.

    A retirement is a rite of passage that requires careful planning, because it forces a retiree to make a shift in the paradigm in life. For 37 years, I was a healing professional, a breadwinner, and a working spouse. I am now a jobless loner, an inactive pensioner, and a homebound spouse. In this retrospective autobiography, I suggest a few points to help my younger colleagues to better their upcoming retirement: professional, financial, social, and familial. To overcome Erikson's identity crisis, I volunteered to be a wounded healer at Warm Springs Indian Reservation. My volunteer medical service at Warm Springs Indian Reservation was a good antidote to creatively overcome my postretirement blues.

    The invention refers to a system for quickly extinguishing a liquid fuel body on fire by insulating it completely from the ambient air. It applies particularly to the case of a high temperature liquid sodium sheet flowing accidentally from a circuit belonging to a fast neutron reactor. The system in question includes a lower receptacle for collecting the liquid fuel and a top cover shutting off the receptacle. This cover has inclined channels to take the liquid fuel flow and openings to allow this liquid through at the bottom end of the channels. These openings are closed by retractable shutters moving away under the pressure of the liquid in the channels and closing automatically after the liquid has flowed into the receptacle [fr

  19. A search for a new gauge boson A'

    Energy Technology Data Exchange (ETDEWEB)

    Jensen, Eric L. [College of William and Mary, Williamsburg, VA (United States)

    2013-08-01

    In the Standard Model, gauge bosons mediate the strong, weak, and electromagnetic forces. New forces could have escaped detection only if their mediators are either heavier than order(TeV) or weakly coupled to charged matter. New vector bosons with small coupling {alpha}' arise naturally from a small kinetic mixing with the photon and have received considerable attention as an explanation of various dark matter related anomalies. Such particles can be produced in electron-nucleus fixed-target scattering and then decay to e+e-+ pairs. New light vector bosons and their associated forces are a common feature of Standard Model extensions, but existing constraints are remarkably sparse. The APEX experiment will search for a new vector boson A' with coupling α'/αfs > 6 × 10-8 to electrons in the mass range 65MeV < mass A' < 550MeV. The experiment will study e+e- production off an electron beam incident on a high-Z target in Hall A at Jefferson Lab. The e- and e+ will be detected in the High Resolution Spectrometers (HRSs). The invariant mass spectrum of the e+e- pairs will be scanned for a narrow resonance corresponding to the mass of the A'. A test run for the APEX experiment was held in the summer of 2010. Using the test run data, an A' search was performed in the mass range 175-250 MeV. The search found no evidence for an A' → e+e-reaction, and set an upper limit of {alpha}'/{alpha}{sub fs} ~ 10-6.

  20. A metaphysical journey in a comatose state.

    Gimenez, R

    1992-01-01

    This paper is about the intense experience of being in the hospital in a comatose state resulting from an aneurysm with a massive brain hemorrhage and two subsequent surgeries. The event begins with a premonition of what will happen from a street name. The experience of brain surgeries, along with the fine care of the nurses, left me with a truly memorable impression. This paper describes the various feelings and strong emotions that I experienced while in a comatose state. It suggests that a patient in a comatose state can exist in a deep state of emotions close to ecstasy. The paper concludes with gratefulness to all the people who followed me step by step on this journey.

    1990-01-01

    Four siblings with hepatic fibrosis are described. The liver damage in these patients was secondary to chronic ingestion of massive doses of vitamin A for congenital ichthyosis. Although the extrahepatic manifestations were helpful in the diagnosis of hypervitaminosis A, the distinctive features of hepatic histopathology were confirmatory. The plasma concentrations of vitamin A and retinol-binding protein were misleading. The recovery from the liver damage in these patients was slow despite a complete withdrawal of the vitamin A intake. These cases show the importance of hepatic vitamin A assessment in the diagnosis of hepatic fibrosis.

    Full Text Available The economic evaluation of a project requires a great deal of diverse information to be brought together in one place. The greatest concern is that there will be an error by omission, so it is useful to have a detailed list of what one needs to know in order to make a thorough evaluation.There are various of detail required at the different stages of evaluation in the project, from the "quick and dirty" overview to the pre-feasibility study, through a full detailed feasibility study, to a due diligence review. This list addresses most of the economic variables in project and can be used at all levels of studies. Its purpose is to identify a variable or issue and to raise a question, which the review can pursue in more detail using an increasingly more comprehensive checklist for each topic. While developed from the point of view of a new project, this list is equally valid for an ongoing operation.A feasibility study is defined as an assessment of all aspects of a project including technical, infrastructural, environmental, social, legislative and commercial factors, which is sufficiently detailed to support a decision on the implementation. Each project has an associated level of risk. For a proposed investment to increase the value of a firm's stock, it should have a higher expected rate of return than shareholders require for assuming that risk. Since investors demand for a higher potential returns from a riskier project, the cost of capital depends on the venture's risk.

    To develop assistive technology that would help an older person to arise from a kneeling position to a standing one. Developing a prototype, based on an inclusive design and then testing the prototype to verify the approach. The prototype was subsequently tested by a panel of 20 elderly users. These tests were observed and filmed. Participants' experiences of being lifted with the elevation seat were registered with the VIDAR ergonomic assessment system. None of the 20 participants used a walker at that time. In response to a question of whether, assuming they might have to use a walker in the future, they thought that a walker with an elevating seat would be helpful, 18 said that it would. Two of the participants did not believe that they would ever have to use a walker. A simple assistive technology such as a walker equipped with an elevating seat would in many of these cases simplify matters and reduce the distress of people who fall often. In addition, such a device can allow people who fall often to live in their homes longer. For caregivers dealing frequently with people who fall, this assistive device can contribute to decreasing occupational injuries. Development of a lifting device that can help people raise themselves up entirely on their own, or with minimal assistance, would be a revolutionary step for the individual. Lifting devices in use today requires much more extensive assistance from home helpers or others and due to the risk of injuries it is a great value for the helpers that easy to use devices develops. A walker equipped with an elevating seat could even provide a potential for people to stay in their homes longer.

    Coffee, tea, chocolate and caffeinated drinks are the main sources of caffeine, which is consumed in almost all ages and socioeconomic levels. Caffeine acts as a non-selective adenosine receptor antagonist in the central nervous system. Its main effects are as psychostimulant, acting in addition on the respiratory, muscular and cardiovascular systems. Basically, caffeine is metabolized by the hepatic cytochrome P-450 1A2 enzymes (CYP1A2). Several drugs can interact with its metabolism. The observed interindividual differences of its effects can be explained by variations in its metabolism. The main therapeutic use of caffeine is bronchodilator in respiratory diseases. Other possible uses are under investigation. Acute or chronic consumption of caffeine can induce several adverse effects, including intoxication that can be lethal. Finally, caffeine can be considered a drug of abuse. It has positive reinforcing actions, produces tolerance, and a withdrawal syndrome after stopping its consumption. Caffeine can cause different mental disorders such as dependence, which is not included in the DSM-IV-R, withdrawal syndrome and intoxication. Depending on its use, caffeine can be considered a nutrient, a drug or a drug of abuse.

    2013-12-01

    Full Text Available This article addresses an ethically weighted problem which is related to modern psychology: when a person lives in a closed environment. A new approach to solving this problem is being examined. It is based on the finding of substantial new functional aspects of the cognitive processes of making and losing meaning. The study of this sub-discipline started with O.K. Tikhomirov’s theory of thinking. The phenomenon of “adaptability to changes in lifestyle” is being analyzed. The substantial characteristics of the notion of a “closed environment” as well as the psychological manifestations which appear when one is forced to live in a closed environment or choses to live in one of his or her own volition are being revealed. According to the author, the new approach will allow us to come closer to understanding and being able to explain the psychological mechanisms of the mental upheaval which prisoners in solitary confinement experience.

    Science cafés (a.k.a. café scientifiques) engage unconventional adult audiences and help researchers hone their communication skills in a relaxed and fun setting. Typically held in restaurants and pubs, science cafés provide a comfortable place for the public to speak with a scientist. National and local evaluations of the café format indicate that café are an effective way to engage adult audiences (especially non-scientists). Continued media coverage also demonstrates that something about them captures the public's imagination. This paper is based on an interactive oral presentation about organizing, presenting, and partnering with science café to bring IYA themes (and other current research) directly to new audiences. Real world examples from experienced café organizers and presenters provide an overview of what a science café is, how to start one, and how to use the format to draw attention to astronomy topics. The discussion includes suggestions for tapping into the existing national and international community of cafés (there are more than 60 in the U.S. alone), and information about free outreach resources. Break-out exercises in the original oral presentation were designed to help prepare participants to: find a suitable venue, advertise, work with café speakers, and foster the inclusive conversation that is the hallmark of a science café. Participants also learned about the impacts that can be expected from a science café, including benefits to audiences, café presenters, and hosting organizations. The overall goal of the original oral presentation was to stimulate a discussion about strategies for facilitating face-to-face communication between scientists and lay audiences.

    1995-01-01

    Computerized medical record systems (CPRS) should present user and problem oriented views of the patient file. Problem lists, clinical course, medication profiles and results of examinations have to be recorded in a computerized patient record. Patient review screens should give a synopsis of the patient data to inform whenever the patient record is opened. Several different types of data have to be stored in a patient record. Qualitative and quantitative measurements, narratives and images are such examples. Therefore, a CPR must also be able to handle these different data types. New methods and concepts appear frequently in medicine. Thus a CPRS must be flexible enough to cope with coming demands. We developed a prototype of a computer based patient record with a graphical user interface on a SUN workstation. The basis of the system are a dynamic data dictionary, an interpreter language and a large set of basic functions. This approach gives optimal flexibility to the system. A lot of different data types are already supported. Extensions are easily possible. There is also almost no limit concerning the number of medical concepts that can be handled by our prototype. Several applications were built on this platform. Some of them are presented to exemplify the patient and problem oriented handling of the CPR.

    Full Text Available A vitamina A é essencial à preservação e ao funcionamento normal dos tecidos, assim como, ao crescimento e desenvolvimento. No humano há evidência indireta que a vitamina A em excesso, durante as primeiras semanas de gestação é teratogênica. Do contrário, não há dúvidas sobre os efeitos deletérios, de uma alimentação carente neste micronutriente e sobre a disponibilidade do conhecimento técnico para evitá-los. A preocupação com o fato de que a vitamina A conduziria a teratogenia em humanos, tem retardado a implementação de programas de combate a carência de vitamina A, atingindo principalmente os programas de enriquecimento de alimentos. A literatura é controvertida e dispõe de poucas informações sobre as doses para suplementação de gestantes. Como o retinol circulante materno é controlado homeostaticamente após o consumo de alimentos fonte de vitamina A, espera-se a mesma resposta metabólica após o consumo de alimentos fortificados, indicando que não há risco de teratogenia. Consequentemente, parece altamente improvável que o consumo de alimentos enriquecidos ou de suplementos de vitamina A pré-formada, nas doses unitárias habituais, tenha efeito teratogênico no homem.The vitamin A is essential to the preservation and the normal functioning of tissues, as well as, to the growth and development. In the human being it has indirect evidence that the vitamin A in excess, during the first weeks of gestation is teratogenic. Of the opposite, it does not have doubts on the deleterious effect, of a devoid feeding in this micronutrient and on the availability of the knowledge technician to prevent them. The concern with the fact of that the vitamin A would lead it the teratogenicity in human beings, has delayed the implementation of combat programs the vitamin A lack, mainly reaching the programs of food enrichment.

    Full Text Available It has been established that intense emotions can affect the development and course of cardiac arrhythmias. This study sought to convey that a lack of expression of emotion can also have an effect on arrhythmias. A psychotherapist with Idiopathic Ventricular Fibrillation and an Implantable Cardioverter Defibrillator measured his rate of Premature Ventricular Contractions using a Holter monitor during three separate six-week periods and in three domains: A work days vs. off days, B a 27 hour work week vs. 22 hour work week, and C in 5 different modalities including 1 Meeting with department head 2 Individual psychotherapy with patients 3 Group therapy with patients 4 Supervision of residents 5 Personal psychoanalysis. The results showed more than a 3-fold increase of arrhythmogenic activity during the 27-hour work week vs. 22 and a 5-fold increase in arrhythmogenic activity on work days compared to days off. Department Head meetings were found to be most arrhythmogenic and personal psychoanalysis was least. The data suggest that the psychiatrist’s lack of emotional expression in his clinical work has been demonstrated to markedly worsen his arrhythmia. The results also point to the potential ameliorating effects of the therapist’s own psychotherapy.

  16. Pellets - A fuel with a future

    International Nuclear Information System (INIS)

    2004-01-01

    This special brochure presents a series of articles on the topic of wood pellets as a fuel of the future. Dr. Walter Steinmann, director of the Swiss Federal Office of Energy (SFOE) introduces the topic, stressing that the Swiss Confederation and the Cantons are supporting efforts to increase the sustainable use of wood fuels. Further articles take a closer look at pellets and their form. Pellets-fired heating units are introduced as a viable alternative to traditional oil-fired units. Tips are presented on the various ways of storing pellets. Quality-assurance aspects are examined and manufacturers and distributors of wood pellets are listed. A further article takes a closer look at a large Swiss manufacturer of pellets and describes the production process used as well as the logistics necessary for the transportation of raw materials and finished products. The brochure also presents a selection of pellet ovens and heating systems from various manufacturers. A further article illustrates the use of pellets as a means of heating apartment blocks built to the MINERGIE low-energy-consumption standard. In the example quoted, the classic combination of solar energy for the pre-heating of hot water and pellets for the central heating and hot water supply is used. The use of a buried spherical tank to store pellets - and thus the saving of space inside the building - is described in a further article that takes a look at the refurbishment of the heating system in a single-family home. Finally, various contributions presented at the Pellets Forum held in Berne in November 2003 are summarised in a short article

    1989-01-01

    A beam scraper using a linear motor drive has been developed for use in the AGS at Brookhaven National Laboratory. The device is used to measure beam size by moving a target to a predetermined location and measuring the intercepted beam with nearby loss monitors or by noting the decrease in the circulating beam current. This device has excellent vacuum characteristics, as the motor and sensor coils are outside the vacuum, coupled magnetically to the moving parts which, are inside. There are no bellows or dynamic seals required. The position-time profile is controlled by a closed-loop servo system which uses position feedback. 2 refs., 4 figs

    Seckel syndrome, first defined by Seckel in 1960, is a rare (incidence 1:10,000), genetically heterogeneous autosomal recessive disorder presenting at birth. This syndrome is characterized by a proportionate dwarfism of prenatal onset, a severe microcephaly with a "bird-headed" like appearance (beaked nose, receding forehead, prominent eyes, and micrognathia), and mental retardation. The significance of dental alterations in this syndrome resides in the defect, hypoplastic enamel, being limited to the primary dentition; in most instances the second primary molar tooth is not affected. A case of the Seckel syndrome is presented.

    2014-08-13

    We morph a silver nanodisk into a nanotriangle by producing a series of nanoparticles with electron beam lithography. Using electron energy loss spectroscopy (EELS), we map out the plasmonic eigenmodes and trace the evolution of edge and film modes during morphing. Our results suggest that disk modes, characterized by angular order, can serve as a suitable basis for other nanoparticle geometries and are subject to resonance energy shifts and splittings, as well as to hybridization upon morphing. Similar to the linear combination of atomic orbitals (LCAO) in quantum chemistry, we introduce a linear combination of plasmonic eigenmodes to describe plasmon modes in different geometries, hereby extending the successful hybridization model of plasmonics.

  6. A face in a (temporal) crowd.

    2018-03-20

    Familiar objects, specified by name, can be identified with high accuracy when embedded in a rapidly presented sequence of images at rates exceeding 10 images/s. Not only can target objects be detected at such brief presentation rates, they can also be detected under high uncertainty, where their classification is defined negatively, e.g., "Not a Tool." The identification of a familiar speaker's voice declines precipitously when uncertainty is increased from one to a mere handful of possible speakers. Is the limitation imposed by uncertainty, i.e., the number of possible individuals, a general characteristic of processes for person individuation such that the identifiability of a familiar face would undergo a similar decline with uncertainty? Specifically, could the presence of an unnamed celebrity, thus any celebrity, be detected when presented in a rapid sequence of unfamiliar faces? If so, could the celebrity be identified? Despite the markedly greater physical similarity of faces compared to objects that are, say, not tools, the presence of a celebrity could be detected with moderately high accuracy (∼75%) at rates exceeding 7 faces/s. False alarms were exceedingly rare as almost all the errors were misses. Detection accuracy by moderate congenital prosopagnosics was lower than controls, but still well above chance. Given the detection of the presence of a celebrity, all subjects were almost always able to identify that celebrity, providing no role for a covert familiarity signal outside of awareness.

It aims at discussing the issues raised by such a relationship and highlights healthcare-related designs. It questions the notion of product acceptance and points out some challenges that need to be met by designers and engineers. The overall experience provided by owning and using a product must be designed in a holistic way, placing the human, his or her needs and feelings, as central guiding factors. These issues are further explained with the presentation of a design project made by Audrey Dodo and Teresa Georgallis, within the frame of a competition at the Royal College of Art in London: a self-monitoring health service, a toothbrush that assesses the user’s health state through his or her mobile phone.

    1988-01-01

    A Mars rover must be able to sense its local environment with sufficient resolution and accuracy to avoid local obstacles and hazards while moving a significant distance each day. Power efficiency and reliability are extremely important considerations, making stereo correlation an attractive method of range sensing compared to laser scanning, if the computational load and correspondence errors can be handled. Techniques for treatment of these problems, including the use of more than two cameras to reduce correspondence errors and possibly to limit the computational burden of stereo processing, have been tested at JPL. Once a reliable range map is obtained, it must be transformed to a plan view and compared to a stored terrain database, in order to refine the estimated position of the rover and to improve the database. The slope and roughness of each terrain region are computed, which form the basis for a traversability map allowing local path planning. Ongoing research and field testing of such a system is described.

    When parents are expecting, the child is usually awaited with hope and plans and reflections on how to share the life and future with this new child. As such the child opens the parents' perspective to a new future, a span of time or potentiality, a certain narrative—that is, being parents, raising...... a child. When a child is stillborn or dies at a very young age, this event not only turns off all hopes for this particular child, but also all good things envisioned for the child and his or her family, the world itself changes radically. At the Danish website Mindet.dk, parents engage in ritualizations...... and are not about “translating” the everyday experience into, for instance, a religious realm. Rather “the work of ritual … involves developing repertoires that operate in complex interplay with the world of everyday experience” and, eventually, through time and repetition, lead to re-experiencing life....

  12. A PULSED, PRECESSING JET IN CEPHEUS A

    International Nuclear Information System (INIS)

    Cunningham, Nathaniel J.; Moeckel, Nickolas; Bally, John

    2009-01-01

    We present near-infrared H 2 , radio CO, and thermal infrared observations of the nearby massive star-forming region Cepheus A (Cep A). From H 2 bow shocks arranged along four distinct jet axes, we infer that the massive protostellar source HW2 drives a pulsed, precessing jet that has changed its orientation by about 45 deg. in roughly 10 4 years. The current HW2 radio jet represents the most recent event in this time series of eruptions. This scenario is consistent with the recent discovery of a disk around HW2, perpendicular to the current jet orientation, and with the presence of companions at projected distances comparable to the disk radius. We propose that the Cep A system formed by the disk-assisted capture of a sibling star by HW2. We present a numerical model of a 15 M sun star with a circumstellar disk, orbited by a companion in an inclined, eccentric orbit. Close passages of the companion through or near the disk result in periods of enhanced accretion and mass loss, as well as forced precession of the disk and associated orientation changes in the jet. The observations reveal a second powerful outflow that emerges from radio source HW3c or HW3d. This flow is associated with blueshifted CO emission and a faint H 2 bow shock to the east, and with HH 168 to the west. A collision between the flows from HW2 and HW3c/d may be responsible for X-ray and radio continuum emission in Cep A West.

    Alkin, Marvin C

    2017-08-01

    This discussion comments on the approximately 20years history of writings on the prescriptive theory called Empowerment Evaluation. To do so, involves examining how "Empowerment Evaluation Theory" has been defined at various points of time (particularly 1996 and now in 2015). Defining a theory is different from judging the success of a theory. This latter topic has been addressed elsewhere by Michael Scriven, Michael Patton, and Brad Cousins. I am initially guided by the work of Robin Miller (2010) who has written on the issue of how to judge the success of a theory. In doing so, she provided potential standards for judging the adequacy of theories. My task is not judging the adequacy or success of the Empowerment Evaluation prescriptive theory in practice, but determining how well the theory is delineated. That is, to what extent do the writings qualify as a prescriptive theory. Copyright © 2016 Elsevier Ltd. All rights reserved.

  19. Is the A1 a resonance

    International Nuclear Information System (INIS)

    Morgan, D.

    1975-06-01

    Data on diffractive and charge exchange 3π production in the Jsup(P) = 1 + state are shown to favour a resonance interpretation, although with a somewhat higher mass than the conventional A 1 bump. Data are fitted using a two-component model for the production amplitude. The first component comprises the Deck (Born) contribution and its re-scattering corrections; the second represents the so-called 'direct-production' term. The conventional isobar approximation to unitarity is demanded; this forbids the intrusion of additional phases in the Born term, such as arise from projecting a Reggeized Deck amplitude. As a consequence, the phase of the 1 + S 3π production amplitude is predicted to execute a standard resonant variation with Msup(3π). This carries a striking implication for the interfering 'background' waves, 1 + P, 2 - P, 0 - S, relative to which the 1 + S amplitude fails to register any appreciable phase variation in phenomenological analyses. There is no obvious objection to ascribing resonance status to these three channels, of which only one, the 0 - , demands a new (π ') resonance. A running theme, which recurs whenever the results of phenomenological 3-body phase shift analyses are appealed to, is that dynamical features are best viewed in terms of effective matrix elements rather than partial cross-sections.

    Science Cafés (aka Café Scientifiques) engage unconventional adult audiences and help researchers hone their communication skills in a relaxed and fun setting. Typically held in restaurants and pubs, Science Cafés provide a comfortable place for the public to speak with a scientist. National and local evaluations of the Café format indicate that cafes are an effective way to engage adult audiences (especially non-scientists). Continued media coverage also demonstrate that something about them captures the public's imagination. Join us for an interactive session about organizing, presenting and partnering with Science Cafés to bring IYA themes (and other current research) directly to new audiences. Real world examples from experienced Café organizers and presenters will provide an overview of what a Science Café is, how to start one and how to use the format to draw attention to astronomy topics. The discussion will include suggestions for tapping into the existing national and international community of Cafés (there are more than 60 in the US alone), and information about free outreach resources. Break-out exercises will help prepare you to: find a suitable venue, advertise, work with café speakers, and foster the inclusive conversation that is the hallmark of a Science Café. Participants will also learn about the impacts that can be expected from a Science Café including benefits to audiences, Café presenters, and hosting organizations. The overall goal of this session is to stimulate a discussion about strategies for facilitating face-to-face communication between scientists and lay audiences. Participants will have the opportunity to create their own promotional plan for a Café event, including the important process of framing a topic to grab public attention, and developing strategies for reaching new target audiences. Substantial time will be allowed for participants to discuss how the Science Café format might be adapted for their specific

    Full Text Available A business can be launched by establishing a new entity, purchasing an existing entity or through a franc - hise. There are certain prerequisites for starting a business, the most important ones being a quality idea and start-up capital. Potential start-up difficulties are inadequate financing, existing competition as well as the process of building your own market position. By purchasing an existing business some risks may be avoided and the opportunity for gaining profit may arise. Profitable operation is possible only if this business has up-to-date products and no outstanding liabilities. This paper discusses franchising business opportunities and the requisite investments and costs, which will bring success if they are accompanied by franchisee’s efforts. The paper aims to present the main characteristics of a franchise business, the necessary investment and the costs which arise in the process, as well as advantages, disadvantages and experiences with this kind of business

As a birthday present we will offer him a charged medium which gives such a potential purely in the framework of electrodynamics. We realize that this is just a toy and not the mechanism realized in nature. There it is supposed to emerge from QCD where also nonlinear and quantum effects are important.

    Full Text Available Hoarding is a psychological disorder characterized by excessive collecting, storage and inability to discard large quantities of the objects, usually accompanying a severe level of distress or dysfunctionality. Despite the concept has been known for more than a century, it used to be conceptualized as a component of obsessive compulsive disorder. However, hoarding disorder appears as a distinct psychiatric disorder in the last updated version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5. Accordingly, in this review we aimed to make a general framework in understanding of hoarding disorder which is an attention-grabbing diagnosis in these days. In this regard, we addressed the etiology, clinical features of, and treatment approaches to hoarding disorder.

  5. Does a point lie inside a polygon

    Milgram, M.S.

    1988-01-01

    A superficially simple problem in computational geometry is that of determining whether a query point P lies in the interior of a polygon if it lies in the polygon's plane. Answering this question is often required when tracking particles in a Monte Carlo program; it is asked frequently and an efficient algorithm is crucial. Littlefield has recently rediscovered Shimrat's algorithm, while in separate works, Wooff, Preparata and Shamos and Mehlhorn, as well as Yamaguchi, give other algorithms. A practical algorithm answering this question when the polygon's plane is skewed in space is not immediately evident from most of these methods. Additionally, all but one fails when two sides extend to infinity (open polygons). In this paper the author review the above methods and present a new, efficient algorithm, valid for all convex polygons, open or closed, and topologically connected in n-dimensional space (n ≥ 2)

    1975-01-01

    This invention concerns a system for biasing a differential amplifier. It particularly applies to the integrated differential amplifiers designed with MOS field effect transistors. Variations in the technological parameters may well cause the amplifying transistors to work outside their usual operational area, in other words outside the linear part of the transfer characteristic. To ensure that these transistors function correctly, it is necessary that the value of the voltage difference at the output be equally null. To do this and to centre on the so called 'rest' point of the amplifier transfer charateristic, the condition will be set that the output potentials of each amplifier transistor should have a zero value or a constant value as sum. With this in view, the bias on the source (generally a transistor powered by its grid bias voltage) supplying current to the two amplifying transistors fitted in parallel, is permanently adjusted in a suitable manner [fr

    The formation of a contrail from an aircraft flying near the tropopause is simulated using a three-dimensional mesoscale atmospheric model including a very complex scheme of parameterized cloud microphysical processes. The model predicted ice concentrations are in very good agreement with data measured during the International Cirrus Experiment (ICE), 1989. Sensitivity simulations were run to determine humidity forcing on the life time of contrails. (author) 4 refs.

    A beam of ThO molecules has been used to make the most precise measurement of the electron’s electric dipole moment (EDM) to date. In their recent paper, the ACME collaboration set out in detail their experimental and data analysis techniques. In a tour-de-force, they explain the many ways in which their apparatus can produce a signal which mimics the EDM and show how these systematic effects are measured and controlled.

    Listeriosis is a food-borne illness leading to bacteriemia or central nervous system infection especially in pregnant women or high-risk patients. It is rarely a localized infection. Breast contamination has rarely been reported in lactating women. We report a breast abscess in man. A 80 year old man, hypertensive and arrhythmic, was explored for weakness and dehydration. Type 2 diabetes and chronic lymphocytic leukemia were diagnosed. Clinical examination disclosed a breast abcess related to L monocytogenes infection. Histopathological study also revealed a breast subcutaneous infiltration by chronic lymphocytic leukemia. Listeriosis sometimes uncover an unknown immunosuppression, especially in the elderly. Breast is a non-sterile tissue containing a stable microbiome partly from digestive origin. It can thereby be contaminated by Listeria. The specific cutaneous infiltrate of chronic lymphocytic leukemia can create the conditions for a local infection. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

    Conjoined twinning has been reported in most of the domestic animal species. Among them, sheep have the highest incidence of craniofacial defects. A live male crossbreed dystocic two-headed lamb was delivered from a 2-year-old Pinzerita sheep after first mating. After 40 h of life, the lamb spontaneously died. The most important gross findings involved the head, whereas the examination of different organ and tissue sections did not reveal remarkable histomorphological changes. The lamb was classified as a conjoined twinning and, on the basis of the facial duplication, as a diprosopus tetraophtalmus.

    A 75-year-old Japanese woman presented with nausea and appetite loss. Computed tomography showed a radiopaque substance in the stomach. Esophagogastroduodenoscopy revealed bezoars in the stomach, which were endoscopically retrieved. The bezoars were mainly composed of magnesium and oxide. Although bezoar formation associated with magnesium oxide consumption is infrequently encountered, the present case indicates that pharmacobezoar should be considered among the differential diagnoses in patients who demonstrate a radiopaque mass in the digestive tract and have a history of magnesium oxide use.

  18. Parkinson's: a syndrome rather than a disease?

    Science.gov (United States)

    Titova, Nataliya; Padmakumar, C; Lewis, Simon J G; Chaudhuri, K Ray

    2017-08-01

    Emerging concepts suggest that a multitude of pathology ranging from misfolding of alpha-synuclein to neuroinflammation, mitochondrial dysfunction, and neurotransmitter driven alteration of brain neuronal networks lead to a syndrome that is commonly known as Parkinson's disease. The complex underlying pathology which may involve degeneration of non-dopaminergic pathways leads to the expression of a range of non-motor symptoms from the prodromal stage of Parkinson's to the palliative stage. Non-motor clinical subtypes, cognitive and non-cognitive, have now been proposed paving the way for possible subtype specific and non-motor treatments, a key unmet need currently. Natural history of these subtypes remains unclear and need to be defined. In addition to in vivo biomarkers which suggest variable involvement of the cholinergic and noradrenergic patterns of the Parkinson syndrome, abnormal alpha-synuclein accumulation have now been demonstrated in the gut, pancreas, heart, salivary glands, and skin suggesting that Parkinson's is a multi-organ disorder. The Parkinson's phenotype is thus not just a dopaminergic motor syndrome, but a dysfunctional multi-neurotransmitter pathway driven central and peripheral nervous system disorder that possibly ought to be considered a syndrome and not a disease.

    The Aharon Vaidman (AV) quantum game [1] demonstrates the advantage of using simple quantum systems to outperform classical strategies. We present an experimental test of this quantum advantage by using a three-state quantum system (qutrit) encoded in a spatial mode of a single photon passing through a system of three slits [2,3]. We prepare its states by controlling the photon propagation and the number of open and closed slits. We perform POVM measurements by placing detectors in the positions corresponding to near and far field. These tools allow us to perform tomographic reconstructions of qutrit states and play the AV game with compelling evidence of the quantum advantage

We suppose that there is an exterior field (transmission problem) and that the total field on the sphere is known. We give analytical inversion algorithms for determining the interior physical characteristics of the sphere as well as the location, strength and orientation of the source/dipole. We start with static problems (Laplace’s equation) and then proceed to acoustic problems (Helmholtz equation). (paper)

    A case of a ruptured dermoid cyst presenting headaches and dizziness as the only symptoms is presented. A 60-year-old woman was admitted to our hospital after complaining of headaches for 5 years and of dizziness for 1 week. The results of physical and neurological examinations were normal. An X-ray of the skull revealed an intracranial calcification in the left frontal region. CT disclosed calcification and a large low-density area in the left parasellar region and the frontal lobe. The mass consisted of two different areas of density. There were multiple, isolated, low-density spots in the left Sylvian fissure and the interpeduncular cistern. No abnormal enhancement was seen by CECT. Angiograms showed an elevation of the A 1 portion of ACA and a lateral shift of MCA. A left fronto-temporal craniotomy was performed. Chronic or past leptomeningitis was suspected because of the arachnoid-membrane thickening. Multiple fatty globules were present in the left Sylvian fissure. A large, soft, fatty tumor was completely removed. The histologic diagnosis was a dermoid cyst. After this operation, the headaches and dizziness were reduced. It is unclear whether the headaches were caused by the compression of the tumor or by the meningeal irritation of the fatty debris. According to the findings on the arachnoid membrane, however, it seems likely that fatty debris detached from the tumor spilled out intermittently from the cyst into the subarachnoid space, resulting in meningeal irritation.

    2012-01-01

    The binaural beat has been used for over one hundred years as a stimulus for generating the percept of motion. Classically the beat consists of a pure tone at one ear (e.g. 500 Hz) and the same pure tone at the other ear but shifted upwards or downwards in frequency (e.g., 501 Hz). An experiment and binaural computational analysis are reported which demonstrate that a more powerful motion percept can be obtained by applying the concept of the frequency shift to a noise, via an upwards or downwards shift in the frequency of the Fourier components of its spectrum.

    Optic perineuritis is an uncommon inflammatory disorder that involves optic nerve sheath. Numerous case reports have been published on optic perineuritis in adults, the majority of whom had bilateral presentation. There are limited data on optic perineuritis occurring in pediatric patients. We report a teenager who presented with a unilateral sign that mimicked the presentation of optic neuritis. The orbit and brain magnetic resonance imaging confirmed features of unilateral optic perineuritis. She was treated with a high dose of corticosteroids for 2weeks, and her final visual outcome was satisfactory. No signs of relapse were noted during follow-up visits.

  11. Towards a personalized Internet: a case for a full decentralization.

    Science.gov (United States)

    Kermarrec, Anne-Marie

    2013-03-28

    The Web has become a user-centric platform where users post, share, annotate, comment and forward content be it text, videos, pictures, URLs, etc. This social dimension creates tremendous new opportunities for information exchange over the Internet, as exemplified by the surprising and exponential growth of social networks and collaborative platforms. Yet, niche content is sometimes difficult to retrieve using traditional search engines because they target the mass rather than the individual. Likewise, relieving users from useless notification is tricky in a world where there is so much information and so little of interest for each and every one of us. We argue that ultra-specific content could be retrieved and disseminated should search and notification be personalized to fit this new setting. We also argue that users' interests should be implicitly captured by the system rather than relying on explicit classifications simply because the world is by nature unstructured, dynamic and users do not want to be hampered in their actions by a tight and static framework. In this paper, we review some existing personalization approaches, most of which are centralized. We then advocate the need for fully decentralized systems because personalization raises two main issues. Firstly, personalization requires information to be stored and maintained at a user granularity which can significantly hurt the scalability of a centralized solution. Secondly, at a time when the 'big brother is watching you' attitude is prominent, users may be more and more reluctant to give away their personal data to the few large companies that can afford such personalization. We start by showing how to achieve personalization in decentralized systems and conclude with the research agenda ahead.

    Full Text Available For researchers working within a critique of capitalism and its relation to knowledge production, it is problematic to use traditional research methodologies endemic to the very system being critiqued unless they are somehow altered. This article investigates the potential of schizoanalysis to provide conceptual tools for such an approach. Developed through the collaborative work of Deleuze and Guattari, schizoanalysis operates from the organic principle that knowledge is an indivisible part of the way we live in the world. However, schizoanalysis is not a research methodology; it inserts itself into research methodologies, warps them, and reproduces itself through them.

    A-THREE is an optical-model code for elastic scattering, specifically designed for the requirements of heavy-ion projectiles. Fast search procedures for fitting model parameters to experimental data are provided. Because of structural similarity, provision for bound-state calculation is also included. In a sense, this code is ''grandson of ABACUS-2;'' it has, however, been written completely anew. Principal features include the ability to calculate to high partial waves (up to l = 800), refinement of integration meshes for large wave number, and a variety of forms for the optical potentials. The very superior Manchester Coulomb Wave Functions Routine, good in all parts of the (rho, eta) plane is used. This code, written in Fortran-extended, has been in use at Brookhaven on its CDC-7600 for the last two years, during which a number of minor improvements have been added. A general overview of the principal features of the code is given first, with some recommendations for input. This overview is intended to guide the user, and is not intended as a detailed description of the code. Then follow sections describing the input cards and the output generated by the code. These sections are sufficiently detailed to permit a user to prepare input without reference to a code listing. Finally, material necessary for writing special potential well subroutines and tables of control and parameter numbers are appended

    Gatesy, John; Geisler, Jonathan H; Chang, Joseph; Buell, Carl; Berta, Annalisa; Meredith, Robert W; Springer, Mark S; McGowen, Michael R

    2013-02-01

    The emergence of Cetacea in the Paleogene represents one of the most profound macroevolutionary transitions within Mammalia. The move from a terrestrial habitat to a committed aquatic lifestyle engendered wholesale changes in anatomy, physiology, and behavior. The results of this remarkable transformation are extant whales that include the largest, biggest brained, fastest swimming, loudest, deepest diving mammals, some of which can detect prey with a sophisticated echolocation system (Odontoceti - toothed whales), and others that batch feed using racks of baleen (Mysticeti - baleen whales). A broad-scale reconstruction of the evolutionary remodeling that culminated in extant cetaceans has not yet been based on integration of genomic and paleontological information. Here, we first place Cetacea relative to extant mammalian diversity, and assess the distribution of support among molecular datasets for relationships within Artiodactyla (even-toed ungulates, including Cetacea). We then merge trees derived from three large concatenations of molecular and fossil data to yield a composite hypothesis that encompasses many critical events in the evolutionary history of Cetacea. By combining diverse evidence, we infer a phylogenetic blueprint that outlines the stepwise evolutionary development of modern whales. This hypothesis represents a starting point for more detailed, comprehensive phylogenetic reconstructions in the future, and also highlights the synergistic interaction between modern (genomic) and traditional (morphological+paleontological) approaches that ultimately must be exploited to provide a rich understanding of evolutionary history across the entire tree of Life.

  12. A support shield for a powered support

    Energy Technology Data Exchange (ETDEWEB)

    Korczynski, P; Rojicek, P

    1982-08-31

    The subject of this invention is a support shield for a powered support. This shield resists creep of the coal from the longwall face, including an inclined longwall. It involves an arrangement wherein the distributor hinge is separated into upper and lower sections. The lower section holds a second hinge and the end of the rod of the pressure cylinder, one end of which is connected to the roof support. An advantage of the support is that compared to existing supports, it is self-advancing and holds stopes with coal which slopes in its formation or has inrushes. To a certain degree it prevents the stope space from ejecting fine pieces of rock from the longwall roof using an inter-timber support between the powered support and the stope. The support shield is moved by a simple system of levers which makes it possible, using a pressurized cylinder, to transmit a significant force to the coal stope. In this case, when the coal inrushes exceed the designed capabilities of the shield, a wooden extension piece is placed between the support and the face, through which the support pressure is applied.

    2017-01-01

    Mandibular fractures are rare in children. Symptoms of these fractures include preauricular pain and swelling, trismus and pain when opening the mouth, and they are often preceded by a fall on the chin. If the diagnosis is missed they may have serious consequences for the growth and development of the jaw. A 3-year-old boy was referred with a swelling in his left cheek, fever and vomiting. Two days earlier he had fallen on his chin. At physical examination he had severe preauricular pain on palpation and a trismus. The patient was admitted because of suspicion of a viral parotitis and the threat of dehydration. After discharge, he went to the dentist for examination of a molar that was painful to the touch. The dentist performed an orthopantomogram and discovered a fracture of the left mandibular collum. Any child with trauma to the chin should be observed for symptoms of a mandibular fracture, and if it seems necessary non-invasive radiographic examination should be performed.

    My first interaction with Jim Holcombe was by letter in late 1977 (well before our instant e-mail communications age we all enjoy and/or curse). Jim was enquiring via some subtle questions about a paper I had recently published in Analytical Chemistry on the mechanisms of atomization in the graphite furnace. This brief correspondence initiated a 35 year period of technical interaction and friendship which literally carried us throughout the world to many conferences and more than a few shared hotel rooms in the days when one would make sacrifices to reduce travel costs to enable conference attendance. At the SciX 2013 (FACSS) meeting in Milwaukee WI, a special symposium was organized by John Molloy in honor of Jim's achievements. This was the closest "public" venue to correspond with Jim's announced 2013 spring retirement and his "exit" from a working career at the Department of Chemistry, University of Texas at Austin. It was a distinct honor for me to have Nicolo Omenetto ask if I would help coordinate this special issue of Spectrochim. Acta, Part B in honor of Jim's career/achievements. This gives me the opportunity to publicly comment on my personal association with this "Texas" gentleman from Colorado, a genuine "out of the box" thinker, a productive, highly acknowledged but humble character that I am grateful to have known, and with whom I have traveled the world and enjoyed so many good times.

    2016-12-01

    We present the second multi-frequency radio detection of a reverse shock in a γ-ray burst. By combining our extensive radio observations of the Fermi-Large Area Telescope γ-ray burst 160509A at z = 1.17 up to 20 days after the burst with Swift X-ray observations and ground-based optical and near-infrared data, we show that the afterglow emission comprises distinct reverse shock and forward shock contributions: the reverse shock emission dominates in the radio band at ≲10 days, while the forward shock emission dominates in the X-ray, optical, and near-infrared bands. Through multi-wavelength modeling, we determine a circumburst density of {n}0≈ {10}-3 {{cm}}-3, supporting our previous suggestion that a low-density circumburst environment is conducive to the production of long-lasting reverse shock radiation in the radio band. We infer the presence of a large excess X-ray absorption column, N H ≈ 1.5 × 1022 {{cm}}-2, and a high rest-frame optical extinction, A V ≈ 3.4 mag. We identify a jet break in the X-ray light curve at {t}{jet}≈ 6 {days}, and thus derive a jet opening angle of {θ }{jet}≈ 4^\\circ , yielding a beaming-corrected kinetic energy and radiated γ-ray energy of {E}{{K}}≈ 4× {10}50 erg and {E}γ ≈ 1.3× {10}51 erg (1-104 keV, rest frame), respectively. Consistency arguments connecting the forward shocks and reverse shocks suggest a deceleration time of {t}{dec} ≈ 460 s ≈ T 90, a Lorentz factor of {{Γ }}({t}{dec})≈ 330, and a reverse-shock-to-forward-shock fractional magnetic energy density ratio of {R}{{B}}\\equiv {ɛ }{{B},{RS}}/{ɛ }{{B},{FS}}≈ 8. Our study highlights the power of rapid-response radio observations in the study of the properties and dynamics of γ-ray burst ejecta.

  8. A multiplicity trigger for a Cherenkov detector

    1984-05-01

    The Multiplicity Trigger (MT) is a device for deciding if, in a given time window, the number of wires that are hit in a multi wire proportional chamber (MWPC) is within given limits. The MT is designed for a Cherenkov detector, using a MWPC with 155 sense wires. It has ten inputs with sixteen channels on each, for 160 ECL input signals from the MWPC. With the MT, it is possible to decide if the number of hits is greater than n out of 160, where n is called the multiplicity. Here, 2 < n < 30, with an accuracy of +- 1. The time window can be adjusted from 0.7 to 4 μs. The MT has four separate NIM outputs, to make it possible to have four different values of n at the same time. The propagation delay from input to output is at the most 100 ns. (author)

  9. PLANT PATHOLOGY: a discipline at a crossroads.

    Science.gov (United States)

    Weinhold, A R

    1996-01-01

    The Department of Plant Pathology at the University of California at Berkeley was destroyed as a consequence of a contentious reorganization. The circumstances that led to the reorganization provide some insight into the challenges facing the discipline of plant pathology. The underlying basis for plant pathology as a science is to address problems of plant disease. This requires a balance between disciplinary and problem-solving research and a continuum from achieving fundamental advances in knowledge to the development and implementation of problem-solving approaches. Changes in colleges and universities have placed extreme stress on this essential structure. The dilemma that must be addressed is how to reestablish the problem-solving continuum where it has been broken and strengthen it where it has been weakened. Plants are essential for life, and they will always be affected by disease. The understanding and management of these diseases is the responsibility and the challenge of plant pathology today and in the future.

  10. A model for a stable coronal loop

    International Nuclear Information System (INIS)

    Hoven, G.V.; Chiuderi, C.; Giachetti, R.

    1977-01-01

    We present here a new plasma-physics model of a stable active-region arch which corresponds to the structure observed in the EUV. Pressure gradients are seen, so that the equilibrium magnetic field must depart from the force-free form valid in the surrounding corona. We take advantage of the data and of the approximate cylindrical symmetry to develop a modified form of the commonly assumed sheared-spiral structure. The dynamic MHD behavior of this new pressure/field model is then evaluated by the Newcomb criterion, taken from controlled-fusion physics, and the results show short-wavelength stability in a specific parameter range. Thus we demonstrate the possibility, for pressure profiles with widths of the order of the magnetic-field scale, that such arches can persist for reasonable periods. Finally, the spatial proportions and magnetic fields of a characteristic stable coronal loop are described

    1996-01-01

    This contribution covers hadron production in collisions between nuclei in the laboratory energy range from a few hundred MeV/nucleon, where pion production starts to play a non negligible role, to a few hundred GeV/nucleon, still below the region where jets come into play. Only hadron production by the strong interaction process is considered. The main emphasis will be on π- and K-mesons. Hyperons and antibaryons will be mentioned at the highest energy only. In this presentation only a small part of the huge field of hadronic particle production in a wide beam energy interval can be dealt with. The author's choice of experimental data should be considered to represent his field of interest and activity. (author)

    Full Text Available Schwannoma, a benign nerve sheath tumor is relatively rare in occurrence and even rarer in sites, such as jaw bones. There are only 45 reported cases of intraosseous schwannoma of the jaws reported in the literature. We report a rare case of mandibular schwannoma in a 50-year-old Indian male. The clinical features resembled that of a residual cyst, fibro-osseous lesion or an odontogenic tumor/cyst. Radiological differential diagnoses of ameloblastoma or odontogenic keratocyst was made based on the findings of the orthopantomogram. The lesion was examined histopathologically and a final diagnosis of schwannoma arising from the inferior alveolar nerve was made. The aim of this report is to add information to the existing sparse literature on intraosseous schwannomas of the jaw.

The percentage of body surface area with sunburn was determined......-specific UVR doses after adjustment for sun protection factor. Remarkably, we found that all volunteers sunburned at some point. The risk of sunburn correlated significantly with the adjusted body site-specific UVR dose. Furthermore, there was also a significant relationship between the daily UVR dose...... and percentage of body surface area with sunburn. Our study shows that holiday UVR exposure results in a high risk of sunburn, which potentially increases the risk of skin cancer. Possible protection by melanogenesis is insufficient to protect against sunburn during a 1-week sun holiday. Finally, our data...

  15. Is zucchini a phosphodiesterase or a ribonuclease?

    2014-12-01

    Full Text Available Zucchini (Zuc, a member of the phospholipase D (PLD superfamily, is essential for the primary PIWI-interacting RNA (piRNA biogenesis and the suppression of transposon expression, which are crucial for the genome integrity of germline cells. However, it has been ambiguous whether Zuc acts as a phosphodiesterase to produce phosphatidic acid (PA, the lipid signaling molecule, or as a nuclease. The recent three papers describing the crystal structures and functional analyses of fly and mouse Zuc proteins have elucidated that Zuc is a PLD family single-strand ribonuclease, not a phosphodiesterase, and functions in the maturation of primary piRNAs. This review will discuss in detail how the crystal structures clearly predict the function of Zuc, which is subsequently demonstrated by biochemical analysis to conclude the previous controversial discussion on the real function of Zuc.

    Full Text Available o artigo focaliza um mito indígena sobre a cabeça voadora e voraz, registrado pela autora em vários grupos indígenas da Amazônia, como os Tupari, os Macurap, os Jabuti, os Aruá, os Sateré-Mawé. Cada versão do mito tem um enredo diferente, mas o tema intrigante é sempre o mesmo: a mutilação do corpo, a cabeça que se transforma ou cola-se num outro ser. Procura-se mergulhar no significado desse mito, ao qual Claude Lévi-Strauss dedicou boa parte de dois livros magistrais, A origem das maneiras da mesa e A oleira ciumenta, e que foi usado por Mário de Andrade no livro clássico sobre o herói brasileiro, Macunaína, uma das poucas obras de fição brasileira a se inspirar em temas e personagens míticos indígenas. O registro de campo desse mito é uma pequena ponta de um amplo trabalho de documentação da tradição e dos mitos indígenas brasileiros, que a autora vem realizando há alguns anos. A intenção, nesse texto, é compreender a riqueza do imaginário indígena brasileiro, insistir na necessidade de documentar culturas que são nossas contemporâneas e ainda bastante desconhecidas. A fição e a arte brasileiras poderiam ampliar muito o seu universo ao explorar e tentar compreender as raízes brasileiras que nos são dadas por mais de 200 povos indígenas do país.

    Knowles, Helena S.; Kara, Dhiren M.; Atatüre, Mete

    2017-09-01

    The sensing capability of a single optically bright electronic spin in diamond can be enhanced by making use of proximal dark nuclei as ancillary spins. Such systems, so far realized only in bulk diamond, can provide orders of magnitude higher sensitivity and spectral resolution in the case of magnetic sensing, as well as improved readout fidelity and state storage time in quantum information schemes. Nanodiamonds offer opportunities for scanning and embedded nanoscale probes, yet electronic-nuclear spin complexes have so far remained inaccessible. Here, we demonstrate coherent control of a 13C nuclear spin located 4 Å from a nitrogen-vacancy center in a nanodiamond and show coherent exchange between the two components of this hybrid spin system. We extract a free precession time T2* of 26 μ s for the nuclear spin, which exceeds the bare-electron free-precession time in nanodiamond by two orders of magnitude.

    Secondary School Feature Articles * Animating Reactions: A Low-Cost Activity for Particle Conceptualization at the Secondary Level, by Robert W. Milne, p 50. * The Gravity of the Situation, by Damon Diemente, p 55. You must be the change you wish to see in the world. Mahatma Ghandi The beginning of a new year always brings with it a feeling of anticipation, a desire to achieve new goals, and a certain urgency to accomplish. Beginning the last year of the 1900s seems somehow to amplify these feelings. This week I was reminded twice of the challenge that lies in focusing on those things that we can change and not being fettered by those we cannot. The first example occurred in my office on a Monday afternoon. A young woman was considering the choice between entering graduate school or seeking a high school teaching position. After approximately 10 years in the workforce, she had entered college and was now within a semester of graduation. While pursuing her studies she had served as a substitute teacher in her home community, believing the experience would affirm her longstanding desire to teach. The behavioral characteristics of some students seemed to be at odds with her memories of high school only a dozen years earlier. Now she was questioning whether she could make a difference in young lives or if she should give up the idea of teaching in high school in favor of graduate degrees in her discipline, which would lead to a career in post-secondary education. Although I assured her that she could indeed have a great impact on high school students, I empathized with the concern she was feeling. The second example occurred the same day, in a class for chemistry majors who are preparing to teach high school chemistry. While considering the importance of performance assessment, with discussion centered on a JCE article ((a href="//1998/jan/abs64.html">Rasp, S. L. J. Chem.

    On December 2010 a sinkhole was suddenly formed close to the eastern flank of Ocna-Mures salt dome. Soon after the collapse the sinkhole was filled with brine forming a salt lake called Plus Lake. The total volume of sinkhole of about 100000 m3 remained constant since February 2011. The Ocna Mures salt dome is situated on the western border of the Transylvanian basin (Romania) and has been exploited for a long time. The ceilings of some shallow mine chambers are now collapsed and filled with brine. Along the eastern flank of the salt dome there is a disturbed zone due to diapirism. Its presence is suggested by the strong fragmentation of rock in the boreholes drilled along the salt-sterile contact, as it resulted from the low values of RQD index. The sinkhole is probably due to a pressure increase along the diapir flank. The causes of this sudden increase of pressure are not well known. Most probably it is due to the damage of the tubing of a flank borehole as mentioned in a technical report of the exploiting company. The injected fresh water expelled through the breaches of the damaged borehole and, due to the high pressure flushed up the crushed material of the disturbed zone. In order to better understand the setting up of the Plus Lake joint research efforts were performed by teams from Bucharest and Basel Universities since 2013. For the geomechanical approach a numerical model was performed using the Flac 7.0 code. In a first stage the creep behavior of salt was analyzed considering a Norton creep law. It resulted that after 100 years the salt reached equilibrium, the creep could be neglected and in a first approximation mechanical equilibrium could be analyzed considering only an elasto-plastic behavior of both the salt and the sterile. For both the salt and the surrounding sedimentary rocks the Mohr-Coulomb criterion was considered. The properties of sterile rocks were estimated following the GSI system. Due to poor rock quality the strength parameters have

    Since the use of antibiotics, bladder necrosis has become a rare condition. We report a case of bladder necrosis in a 90-year-old man following urinary retention. After insertion of a transurethral catheter (TUC), 2 L of urine was evacuated. In the following days, the TUC became intermittently blocked. Adequate bladder drainage could not be obtained despite intensive rinsing and placement of a suprapubic catheter. On surgical exploration necrosis of almost the entire bladder wall, except for the trigone, was encountered. Surgical debridement of the non-viable bladder wall without opening the abdominal cavity was conducted, and a TUC was placed in the Retzius cavity to ensure evacuation of urine. Since the patient was haemodynamically unstable, construction of a urinary diversion was waived and urinary drainage of the Retzius cavity by the TUC was accepted, resulting in adequate urinary drainage without compromising renal function. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

  12. [Utilities: a solution of a decision problem?].

    Science.gov (United States)

    Koller, Michael; Ohmann, Christian; Lorenz, Wilfried

    2008-01-01

    Utility is a concept that originates from utilitarianism, a highly influential philosophical school in the Anglo-American world. The cornerstone of utilitarianism is the principle of maximum happiness or utility. In the medical sciences, this utility approach has been adopted and developed within the field of medical decision making. On an operational level, utility is the evaluation of a health state or an outcome on a one-dimensional scale ranging from 0 (death) to 1 (perfect health). By adding the concept of expectancy, the graphic representation of both concepts in a decision tree results in the specification of expected utilities and helps to resolve complex medical decision problems. Criticism of the utility approach relates to the rational perspective on humans (which is rejected by a considerable fraction of research in psychology) and to the artificial methods used in the evaluation of utility, such as Standard Gamble or Time Trade Off. These may well be the reason why the utility approach has never been accepted in Germany. Nevertheless, innovative concepts for defining goals in health care are urgently required, as the current debate in Germany on "Nutzen" (interestingly translated as 'benefit' instead of as 'utility') and integrated outcome models indicates. It remains to be seen whether this discussion will lead to a re-evaluation of the utility approach.

    Many people take holidays in sunny locations with the express aim of sunbathing. This may result in sunburn, which is a risk factor for skin cancer. We investigated 25 Danish sun seekers during a week's holiday in the Canary Islands. The percentage of body surface area with sunburn was determined by daily skin examinations by the same observer. Erythemally effective ultraviolet radiation (UVR) exposure was assessed with time-stamped personal dosimeters worn on the wrist. Volunteers reported their clothing cover and sunscreen use in diaries, and this information was used to determine body site-specific UVR doses after adjustment for sun protection factor. Remarkably, we found that all volunteers sunburned at some point. The risk of sunburn correlated significantly with the adjusted body site-specific UVR dose. Furthermore, there was also a significant relationship between the daily UVR dose and percentage of body surface area with sunburn. Our study shows that holiday UVR exposure results in a high risk of sunburn, which potentially increases the risk of skin cancer. Possible protection by melanogenesis is insufficient to protect against sunburn during a 1-week sun holiday. Finally, our data clearly support a substantial skin cancer risk from sun holidays. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  14. Grasshoppers as a food source? A review

    2016-01-01

    Full Text Available Description of the subject. Current trends suggest an increasing future demand for conventional meats, which indicates a strong need to shift this dependency to other alternative protein sources such as insects. Literature. From a nutritional point of view, of all the insects consumed globally, grasshoppers are particularly important as a human food. Data from the literature regarding the nutrient composition, amino acid profile, fatty acid profile, mineral composition and vitamin content of grasshoppers as reviewed in this paper, suggest that a number of grasshopper species are a good source of nutrients. It also highlights some of the health related aspects that might arise from the consumption of grasshoppers, mostly linked to agricultural practices and the allergic response of sensitive individuals. The paper also summarizes some religious, social and economic factors that are associated with grasshopper consumption. Conclusions. The success of introducing grasshoppers as a novel food in western countries depends on changes in consumer attitudes. It would be interesting to develop food products derived from grasshoppers in a form acceptable to consumers. Furthermore, it is important to explore the food potential of some grasshopper species native to western countries and to develop their rearing methodologies to enhance availability.

    Full Text Available This article constructs a transmedia topology of the Making a Murderer text, demonstrating influences of various forms of documentary, interactive gaming culture, and post-digital writing on the series itself as well as on the paratextual cloud of works that grew up around it. Here we define transmedia topology as a tracing of what we could call the geography of the text, as defined by its features and boundaries (or lack thereof. We will discuss the intentionality of the series creators, as well as the emergence of a transmedial textuality that is owed largely to audiences and the textual terrain. The Making a Murderer series thus becomes the basis for a larger transmedia narrative that sprawls across social-digital networks, a pastiche of multifarious public reaction and unsanctioned investigation.The article maps the ecologies of interaction, participation and creation with and of the text by the audience to map the thresholds of the transmedial text and investigate new approaches to analysing transmedial work in the context of non-fiction media forms.

    This man could plainly do for mathematics what Brian Cox has done for physics" (Sunday Times). What goes on inside the mind of a rock-star mathematician? Where does inspiration come from? With a storyteller's gift, Cedric Villani takes us on a mesmerising journey as he wrestles with a new theorem that will win him the most coveted prize in mathematics. Along the way he encounters obstacles and setbacks, losses of faith and even brushes with madness. His story is one of courage and partnership, doubt and anxiety, elation and despair. We discover how it feels to be obsessed by a theorem during your child's cello practise and throughout your dreams, why appreciating maths is a bit like watching an episode of Columbo, and how sometimes inspiration only comes from locking yourself away in a dark room to think. Blending science with history, biography with myth, Villani conjures up an inimitable cast of characters including the omnipresent Einstein, mad genius Kurt Godel, and Villani's personal hero, John Nash.

  18. SUPERCOLLIDER: A GEM of a detector

    Anon.

    1993-01-01

    Now being prepared as a major experimental facility for the 87- kilometre Superconducting Supercollider (SSC) being built in Ellis County, Texas, is the GEM detector project. GEM thus becomes the companion to the Solenoidal Detector Collaboration (SDC), the first major SSC detector to emerge (March 1992, page 13). This is in keeping with the SSC Laboratory's aim of two major detectors with overlapping and complementary strengths. GEM is designed to observe all SSC signatures, with emphasis on precise measurement of electrons, photons and muons. Hence the name GEM - ''Gammas, Electrons and Muons.'' Design goals are clean signatures for leptons, jets, and missing transverse energy, maximum sensitivity to narrow resonances, and low backgrounds. Also important is maintaining significant capability at high luminosity (10 34 cm -2 s -1 ). GEM has some distinctive features. A key concept is the exterior magnet, surrounding all detector elements. Inside the magnet are a muon tracking system, a precision calorimeter, and a compact central tracker. This allows the muon momentum to be measured the air of the radiation shielded area outside the thick calorimeter, giving both high precision and robustness at high luminosity. A large magnet gives a large lever arm (at least 4 m) for precise muon momentum measurement. Placing the magnet outside also minimizes the material between tracker and calorimeters, so that the calorimeters are limited only by their inherent resolutions

  19. ViA: a perceptual visualization assistant

    Healey, Chris G.; St. Amant, Robert; Elhaddad, Mahmoud S.

    2000-05-01

    This paper describes an automated visualized assistant called ViA. ViA is designed to help users construct perceptually optical visualizations to represent, explore, and analyze large, complex, multidimensional datasets. We have approached this problem by studying what is known about the control of human visual attention. By harnessing the low-level human visual system, we can support our dual goals of rapid and accurate visualization. Perceptual guidelines that we have built using psychophysical experiments form the basis for ViA. ViA uses modified mixed-initiative planning algorithms from artificial intelligence to search of perceptually optical data attribute to visual feature mappings. Our perceptual guidelines are integrated into evaluation engines that provide evaluation weights for a given data-feature mapping, and hints on how that mapping might be improved. ViA begins by asking users a set of simple questions about their dataset and the analysis tasks they want to perform. Answers to these questions are used in combination with the evaluation engines to identify and intelligently pursue promising data-feature mappings. The result is an automatically-generated set of mappings that are perceptually salient, but that also respect the context of the dataset and users' preferences about how they want to visualize their data.

    2015-12-01

    Hyponatremia is a common electrolyte alteration which has the potential for significant morbidity and mortality. Endocrine disorders, such as primary hypothyroidism and adrenal insufficiency are uncommon causes of hyponatremia. We present the case of a teenager with symptomatic hyponatremia caused by a rare disorder. A 17-year-old boy was admitted to the emergency department with abdominal pain, nausea and vomiting, asthenia, and weight loss. He was in poor general condition, hypotensive, and he had dry mucous membranes and skin as well as mucosa hyperpigmentation. The laboratory findings showed severe hyponatremia, hyperkalemia, and renal dysfunction. The patient started inotropic support and antibiotics. Plasma cortisol and corticotropin levels allowed the diagnosis of primary adrenal insufficiency. He began replacement therapy with hydrocortisone and fludrocortisone, with gradual symptom resolution. An abdominal computed tomography scan showed adrenal hypoplasia. Findings for antiadrenal and antithyroid antibodies were positive, allowing the diagnosis of autoimmune polyglandular syndrome type II. Adrenal insufficiency is a rare disease, especially in children, and its clinical manifestations are due to glucocorticoid and mineralocorticoid deficiency. In most of the cases, symptoms are nonspecific, requiring a high index of clinical suspicion. If the diagnosis and treatment are delayed, acute adrenal insufficiency carries a high morbidity and mortality.

    1993-01-01

    The authors report on progress of work for the past twelve months, and the work which is planned for the coming year. They have been working on the theory of the long range proximity effect discovered experimentally on Bi-Ag-Tl(2223) sandwiches during the period of the previous grant. This has led to the prediction of a novel effect which they refer to as a ''pair echo'' which occurs in these sandwiches and is analogous to the familiar ''spin echo'' seen in certain NMR experiments. Experimentally, they have extended the measurements of the proximity effect to lower temperatures and to other superconductors. They have completed high resolution studies of the thermal difference optical reflectance of the high T c superconductor Tl(2223), for temperatures both above and below the transition temperature, over a photon energy range from 0.3 eV to 5.3 eV. A striking anomaly in this thermal difference spectrum has been found near 1.6 eV, which appears below T c and scales in magnitude with temperature like Δ(T) 2 where Δ(T) is a BCS gap. This is precisely the kind of effect which they had hoped to find, based on a Holstein-like mechanism in these materials, and which they had predicted in a paper on ''Gap Modulation''. The proper interpretation of the effect observed should reveal the mechanism responsible for the superconductivity of the cuprates. They have completed a search for the, so-called Zhang-modes in the above high T c superconductor, Tl(2223) over the same energy range, 0.3 eV to 5.3 eV. These modes are predicted to exist if the proper description of the ground state of the system is that of a Hubbard model

    A vibration sieve is proposed which includes a vibration drive, a body and a screen installed on shock absorbers, a device for washing out the screen, and a subassembly for loading the material. To increase the operational reliability and effectiveness of the vibration sieve by improving the cleaning of the screen, the loading subassembly is equipped with a baffle with a lever which is hinged to it. The device for washing out the screen is made in the form of an electromagnet with a connecting rod, a switch and an eccentric, a friction ratchet mechanism and sprinkling systems. Here, the latter are interconnected, using a connecting rod, while the sprinkling system is installed on rollers under the screen. The electromagnetic switch is installed under the lever. The body is made with grooves for installing the sprinkling system. The vibration sieve is equipped with a switch which interacts with the connecting rod. The friction ratchet mechanism is equipped with a lug.

    Ainhum (dactylolysis spontanea) is a distinct clinical and radiological disorder of dark-skinned people characterized by a progressive development of a constricting band encircling the toe which usually results in spontaneous amputation. Ainhum mainly occurs in African natives, but in times of global migration and tourism, Ainhum is likely to be more often encountered outside Africa. Even though the clinical presentation can mimic more common entities such as arthritis and trauma, the correct diagnosis and treatment is easy if one knows this unusual entity.

    The most fundamental issue in the theory of cosmic strings is addressed by means of Numerical Simulations: the existence of a scaling solution. The resolution of this question will determine whether cosmic strings can form the basis of an attractive theory of galaxy formation or prove to be a cosmological disaster like magnetic monopoles or domain walls. After a brief discussion of our numerical technique, results are presented which, though still preliminary, offer the best support to date of this scaling hypothesis. 6 refs., 2 figs

    We characterized the genome of a highly divergent gyrovirus (GyV8) in the spleen and uropygial gland tissues of a diseased northern fulmar (Fulmarus glacialis), a pelagic bird beached in San Francisco, California. No other exogenous viral sequences could be identified using viral metagenomics. The small circular DNA genome shared no significant nucleotide sequence identity, and only 38–42 % amino acid sequence identity in VP1, with any of the previously identified gyroviruses. GyV8 is the first member of the third major phylogenetic clade of this viral genus and the first gyrovirus detected in an avian species other than chicken. PMID:26036564

    Science.gov (United States)

    McCall, Martin W.; Favaro, Alberto; Kinsler, Paul; Boardman, Allan

    2011-02-01

    We introduce a new type of electromagnetic cloak, the spacetime cloak (STC), which conceals events rather than objects. Non-emitting events occurring during a restricted period are never suspected by a distant observer. The cloak works by locally manipulating the speed of light of an initially uniform light distribution, whilst the light rays themselves always follow straight paths. Any 'perfect' spacetime cloak would necessarily rely upon the technology of electromagnetic metamaterials, which has already been shown to be capable of deforming light in ways hitherto unforeseen—to produce, for example, an electromagnetic object cloak. Nevertheless, we show how it is possible to use intensity-dependent refractive indices to construct an approximate STC, an implementation that would enable the distinct signature of successful event cloaking to be observed. Potential demonstrations include systems that apparently violate quantum statistics, 'interrupt-without-interrupt' computation on convergent data channels and the illusion of a Star Trek transporter.

    Based on the requirements for internal quality assurance in our private practice a model for quality management was implemented. Using such a quality management system (QM-system) resulted in a systematic optimization and higher quality of operating procedures in all work areas. The realization of the new QM-system led to a higher transparency, improved economical efficiency, and an increase in personal motivation. Internal frictional losses could be effectively reduced saving time and money. The efforts in time, costs and personal resources during implementation of the QM-system, which had been considered as downsides in the beginning, are outweighed by the benefits by far according to our experience. In summary: ''We consider it worthwhile in all respects''. (orig.)

  6. A Narrative in Search of a Methodology.

    Science.gov (United States)

    Treloar, Anna; Stone, Teresa Elizabeth; McMillan, Margaret; Flakus, Kirstin

    2015-07-01

    Research papers present us with the summaries of scholars' work; what we readers do not see are the struggles behind the decision to choose one methodology over another. A student's mental health portfolio contained a narrative that led to an exploration of the most appropriate methodology for a projected study of clinical anecdotes told by nurses who work in mental health settings to undergraduates and new recruits about mental health nursing. This paper describes the process of struggle, beginning with the student's account, before posing a number of questions needing answers before the choice of the most appropriate methodology. We argue, after discussing the case for the use of literary analysis, discourse analysis, symbolic interactionism, hermeneutics, and narrative research, that case study research is the methodology of choice. Case study is frequently used in educational research and is sufficiently flexible to allow for an exploration of the phenomenon. © 2014 Wiley Periodicals, Inc.

  8. A spacetime cloak, or a history editor

    International Nuclear Information System (INIS)

    McCall, Martin W; Favaro, Alberto; Kinsler, Paul; Boardman, Allan

    2011-01-01

    We introduce a new type of electromagnetic cloak, the spacetime cloak (STC), which conceals events rather than objects. Non-emitting events occurring during a restricted period are never suspected by a distant observer. The cloak works by locally manipulating the speed of light of an initially uniform light distribution, whilst the light rays themselves always follow straight paths. Any 'perfect' spacetime cloak would necessarily rely upon the technology of electromagnetic metamaterials, which has already been shown to be capable of deforming light in ways hitherto unforeseen—to produce, for example, an electromagnetic object cloak. Nevertheless, we show how it is possible to use intensity-dependent refractive indices to construct an approximate STC, an implementation that would enable the distinct signature of successful event cloaking to be observed. Potential demonstrations include systems that apparently violate quantum statistics, 'interrupt-without-interrupt' computation on convergent data channels and the illusion of a Star Trek transporter

    It was great to be associated with Prof. Dr. Karl Rawer. He devoted his life to make use of the wonderful laboratory of Nature, the Ionosphere. Through acquisition of the experimental data from AEROS satellites and embedding it with data from ground stations, it was possible to achieve a better empirical model, the International Reference Ionosphere. Prof. Dr. Karl Rawer has been as dynamic as the Ionosphere. His vision about the ionospheric data is exceptional and has helped the scientific and engineering community to make use of his vision in advancing the dimensions of empirical modelling. As a human being, Prof. Dr. Karl Rawer has all the traits of an angel from Heaven. In short he developed a large team of researchers forming a blooming tree from the parent node. Ionosphere still plays an important role in over the horizon HF Radar and GPs satellite data reduction.

    2014-02-01

    Full Text Available This study reports on the first successful identification of the site of origin of an extralimital walrus in Europe. On 24 February 2010 an adult male Atlantic walrus (Odobenus rosmarus rosmarus migrant was instrumented with a SPOT-5 satellite-linked transmitter (SLT while hauled out on a beach on the Faroe Islands at 62° 15' N/06° 32' W. This SLT transmitted until 5 March during which period the walrus made local movements, likely for feeding. Transmissions were not received during 6-25 March, however, visual observations during this time indicated that the walrus remained at the Faroe Islands. A second transmitter was deployed on the same animal on 25 March 2010 at another site on the islands (62° 16' N/07° 04' W. Activity data collected over 13 days indicated that the walrus hauled out in three different places in the Faroe Islands and used a total of 24% of its time resting on land.  On 29 March 2010 the walrus left the Faroe Islands and headed WNW towards NE Iceland. On 2 April it took a NNE course and swam towards Svalbard where the last location was received from a sea ice covered area on 25 April 2010 at 78° 27' N/09° 20' E (i.e. ca. 40 km west of the island of Prins Karls Forland in the western Svalbard archipelago. During 29 March-22 April the walrus swam a minimum distance of 2216 km between the last location at the Faroe Islands and the first location at Svalbard, with an average swimming speed of 4.5 km/h. A genetic analysis indicated that this walrus belonged to the Svalbard-Franz Josef Land subpopulation, thereby confirming that it returned to its site of origin.

    McDonald, J. C.

    2012-01-01

    Roman mythology described Janus as the god of beginnings and transitions. Janus was depicted as having two heads facing in opposite directions that could be thought of as the future and the past. Therefore, it is altogether appropriate that the first month of our calendar should be named after Janus because it is a time of passage from the old to the new year. There were a number of significant events and developments during the past year, and one can look forward to a number of new and, perhaps, unexpected developments during the year to come. The year 2011 saw the tragedy of a major earthquake and Tsunami in Japan resulting in a disastrous series of explosions at the Fukushima I Nuclear Power Plant. Releases of radionuclides to the atmosphere and depositions in the immediate vicinity of the plant have required remediation efforts on the part of the Japanese government, with help from a number of other nations. This accident was classified as Level 7, the highest level, on the International Nuclear Event Scale. (author)

  19. Worldviews: A blessing or a curse?

    Directory of Open Access Journals (Sweden)

    Bert Olivier

    2012-10-01

    Full Text Available The concept of a worldview resonates with other concepts, such as those of ‘culture’, ‘civilisation’, and ‘way of life’. Arguably, it is a modern phenomenon, the possibility of which was actualised at the dawn of the modern epoch. Nevertheless, in principle, its ‘possibility’ goes back as far as Plato’s Republic. It is Heidegger, however, who is most informative for understanding what a worldview is, as well as why the modern epoch is its time of provenance. Consequently, an analysis of Heidegger’s essay, ‘The time of the world picture’ (or worldview provided the framework within which it was argued that worldviews are both blessings and curses in the current era: blessings, because, as Harries has argued, we have been disabused of the modern idea of one encompassing worldview or ideology, so that one can no longer believe in only a single ’correct’ view of the world; curses, because they bedevil any wellintended attempts at communicating with understanding on issues of common concern. It was the burden of this article to provide a way of addressing this state of affairs with some hope of transcending the causes of alienation and it is again Heidegger who is the source of such a way, through his notion of the ‘fourfold’.

    Capgras syndrome is a delusional misidentification, a phenomenon where a person believes delusionally that another person (in most cases closely related) has been replaced by a double or impostor of identical appearance. It is usually a symptom of a functional psychosis but sometimes it is also associated with organic cerebral dysfunction. We present a case of a 23-year old women who had the delusional belief that her cat had been replaced by the cat of her former boy-friend. Reviewing the literature we found that such a case is very rare. The association between Capgras syndrome and depersonalisation-derealisation phenomena is also pointed out.

    This article reports an observation on a fat strange repeller, which appears after a characteristic crisis observed in a kicked rotor subjected to a piecewise continuous force field. The discontinuity border in the definition range of the two-dimensional mapping, which describes the system, oscillates as the discrete time develops. At a threshold of a control parameter a fat chaotic attractor suddenly transfers to a fat transient set. The strange repeller, which appears after the crisis, is also a fat fractal. This is the reason why super-transience happens

    Asplund, M.

    2008-10-01

    The conference A Stellar Journey was held in Uppsala, Sweden, 23 27June 2008, in honour of Professor Bengt Gustafsson's 65th birthday. The choice of Uppsala as the location for this event was obvious given Bengt's long-standing association with the city stemming back to his school days. With the exception of a two-year postdoc stint in Copenhagen, five years as professor at Stockholm University and two years as director of the Sigtuna foundation, Bengt has forged his illustrious professional career at Uppsala University. The symposium venue was Museum Gustavianum, once the main building of the oldest university in Scandinavia. The title of the symposium is a paraphrasing of Bengt's popular astronomy book Kosmisk Resa (in English: Cosmic Journey) written in the early eighties. I think this aptly symbolizes his career that has been an astronomical voyage from near to far, from the distant past to the present. The original book title was modified slightly to reflect that most of his work to date has dealt with stars in one way or another. In addition it also gives credit to Bengt's important role as a guiding light for a very large number of students, colleagues and collaborators, indeed for several generations of astronomers. For me personally, the book Kosmisk Resa bears particular significance as it has shaped my life rather profoundly. Although I had already decided to become an astronomer, when I first read the book as a 14-year-old I made up my mind then and there that I would study under Bengt Gustafsson and work on stars. Indeed I have remained true to this somewhat audacious resolution. I suspect that a great number of us have similar stories how Bengt has had a major influence on our lives, whether on the professional or personal level. Perhaps Bengt's most outstanding characteristic is his enthralling enthusiasm. This is equally true whether he is pondering some scientific conundrum, supervising students or performing in front of an audience, be it an

    2013-05-01

    Since 2009, an informal group, comprising four former board members of the International Year of Planet Earth, has been promoting the concept of a so-called Global Geoscientific Initiative. The GGI should: i.Be inclusive, involve a geoscience community, which is broad both in terms of discipline and nationality, and involve the social sciences; ii.Have a clear socio-economic context and global societal relevance; iii.Focus on a globally significant science theme and preferably involve global processes; iv.Attract the support of geoscientific communities, funding agencies, governments and other institutions in many countries, under the umbrella of UNESCO, ICSU and its geoscientific unions. A series of five town hall meetings have been held at which usually three invited, well-respected figures from the geoscientific community gave presentations. Those presentations were followed by discussion about the importance or otherwise of particular areas of science, and the need to engage better with legislators, policy makers, the media and the lay public. No one challenged the desirability of a large-scale programme that would attract researchers from many geoscientific disciplines and potentially involve the geo-unions. The discussions can be summarised under three broad themes: i.Mineral and hydrocarbon resources and their waste products; ii.Living with natural hazards; iii.Strategic Earth science in Africa through the Africa Alive corridors. During the course of development of the GGI, ICSU has issued a number of papers, most recently a strategic plan, covering the period 2012-2017, working parties have been undertaking foresight analysis and there have also been discussions concerning regional environmental change: human action and adaptation with the question "what does it take to meet the Belmont challenge?". The Belmont Forum brings together a number of funding agencies and could provide the resource to enable some initiative to go forward. More recently a programme

    2012-01-01

    With the work for Long Shutdown 1 looming on the horizon, the CERN Fire Brigade is anticipating a heavy workload: more people working at CERN means more call-outs. So the more trained first-aiders around to help out before the paramedics arrive, the better. Would you know what to do in a medical emergency?   It could happen at any time: two colleagues are having a coffee at work, when one suddenly clutches his or her chest and falls to the floor unconscious. What would you do? Run to find a first-aider? Call the ambulance and wait, finishing your coffee? Neither response is entirely correct. On Monday 11 June in Building 40 the CMS safety group, in collaboration with the Fire Brigade and the Medical Service, demonstrated the recommended, potentially life-saving response to cardiac arrest (see the video), including the correct use of a defibrillator, ten of which were recently installed in key CERN locations (the Bulletin reported).     “In countries where...

  18. You are not a gadget a manifesto

    CERN Document Server

    Lanier, Jaron

    2011-01-01

    A programmer, musician, and father of virtual reality technology, Jaron Lanier was a pioneer in digital media, and among the first to predict the revolutionary changes it would bring to our commerce and culture. Now, with the Web influencing virtually every aspect of our lives, he offers this provocative critique of how digital design is shaping society, for better and for worse. Informed by Lanier’s experience and expertise as a computer scientist, You Are Not a Gadget discusses the technical and cultural problems that have unwittingly risen from programming choices—such as the nature of user identity—that were “locked-in” at the birth of digital media and considers what a future based on current design philosophies will bring. With the proliferation of social networks, cloud-based data storage systems, and Web 2.0 designs that elevate the “wisdom” of mobs and computer algorithms over the intelligence and wisdom of individuals, his message has never been more urgent.

In this talk, I start with a discussion of the origin of spin, and then turn to three themes in which spin has been crucial in subatomic physics: a lab to explore physics beyond the standard model, a tool to measure physical observables that are hard to obtain otherwise, a probe to unravel nonperturbative QCD. I conclude with some remarks on a world without spin

    Given a triangular cake and a box in the shape of its mirror image, how can the cake be cut into a minimal number of pieces so that it can be put into the box? 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.

  7. A white book for a greener future

    International Nuclear Information System (INIS)

    2016-01-01

    The energy transition law promulgated in August 2015 and the Paris Agreement in December 2016 have marked the necessity to build an energy mix with a growing up importance given to renewable energy sources. The French Gas Association (AFG) and the gas industry have joint their efforts to promote the advantages of natural gas as a support to the development of renewable energies. The publication of the AFG white book on September 27 is an illustration of this promotional action. This article provides an overview of the 10 proposals of this white book: 1 - promoting all renewable energy sources; 2 - Making energy transition in the regions a success; 3 - Improving air quality thanks to clean mobility; 4 - Reducing greenhouse gas emissions; 5 - Reducing energy consumption in accommodations; 6 - Fighting fuel poverty; 7 - Contributing to the energy security supplies of France; 8 - Making energy taxation more efficient; 9 - Storing energy while accompanying renewable energy sources development; 10 - Promoting innovation

    Schramm, D.N.

    1987-10-01

    Supernova 1987A is reviewed with emphasis on the neutrino observations. It is shown that the results fit well with the expectations for neutrino temperatures (T ∼ 4ε 0 4.5 MeV) and total energy emitted (2ε 0 4 x 10 53 ergs). It is argued that the detection tends to favor collapse models that yield emission for 10 second timescales with a 1ε 0 2 second early accretion phase followed by Kelvin-Helmholtz cooling as opposed to prompt shocks with the immediate onset of cooling. It is also argued that the probable detection of one or more electron scattering event favors a superthermal tail at high energies. Neutrino mass limits and flavor limits are comparable to laboratory experiments. An estimate for future collapse rates in our galaxy of 1/7 year is made based on nucleosynthesis yields. The supernova also has eliminated many axion and majoron models. 69 refs., 3 figs., 27 tabs

  14. Converting a Microwave Oven into a Plasma Reactor: A Review

    Directory of Open Access Journals (Sweden)

    Victor J. Law

    2018-01-01

    Full Text Available This paper reviews the use of domestic microwave ovens as plasma reactors for applications ranging from surface cleaning to pyrolysis and chemical synthesis. This review traces the developments from initial reports in the 1980s to today’s converted ovens that are used in proof-of-principle manufacture of carbon nanostructures and batch cleaning of ion implant ceramics. Information sources include the US and Korean patent office, peer-reviewed papers, and web references. It is shown that the microwave oven plasma can induce rapid heterogeneous reaction (solid to gas and liquid to gas/solid plus the much slower plasma-induced solid state reaction (metal oxide to metal nitride. A particular focus of this review is the passive and active nature of wire aerial electrodes, igniters, and thermal/chemical plasma catalyst in the generation of atmospheric plasma. In addition to the development of the microwave oven plasma, a further aspect evaluated is the development of methodologies for calibrating the plasma reactors with respect to microwave leakage, calorimetry, surface temperature, DUV-UV content, and plasma ion densities.

  15. Melatonin as a radioprotective agent: a review

    International Nuclear Information System (INIS)

    Vijayalaxmi; Reiter, Russel J.; Tan, D.-X.; Herman, Terence S.; Thomas, Charles R.

    2004-01-01

    Melatonin (N-acetyl-5-methoxytryptamine), the chief secretory product of the pineal gland in the brain, is well known for its functional versatility. In hundreds of investigations, melatonin has been documented as a direct free radical scavenger and an indirect antioxidant, as well as an important immunomodulatory agent. The radical scavenging ability of melatonin is believed to work via electron donation to detoxify a variety of reactive oxygen and nitrogen species, including the highly toxic hydroxyl radical. It has long been recognized that the damaging effects of ionizing radiation are brought about by both direct and indirect mechanisms. The direct action produces disruption of sensitive molecules in the cells, whereas the indirect effects (∼70%) result from its interaction with water molecules, which results in the production of highly reactive free radicals such as · OH, · H, and e aq - and their subsequent action on subcellular structures. The hydroxyl radical scavenging ability of melatonin was used as a rationale to determine its radioprotective efficiency. Indeed, the results from many in vitro and in vivo investigations have confirmed that melatonin protects mammalian cells from the toxic effects of ionizing radiation. Furthermore, several clinical reports indicate that melatonin administration, either alone or in combination with traditional radiotherapy, results in a favorable efficacy:toxicity ratio during the treatment of human cancers. This article reviews the literature from laboratory investigations that document the ability of melatonin to scavenge a variety of free radicals (including the hydroxyl radical induced by ionizing radiation) and summarizes the evidence that should be used to design larger translational research-based clinical trials using melatonin as a radioprotector and also in cancer radiotherapy. The potential use of melatonin for protecting individuals from radiation terrorism is also considered

    The crash has happened and we face dual market failures: climate change and the greatest economic crisis of our lifetimes. American labor believes that we must have a strategic approach to greening the economy centered on domestic investment in new technologies, the creation of good jobs, and leading a shared international response to both these issues. The nay-sayers are the same financial and industrial interests that advised the world economy into chaos. Their advice to us is more of the same: no rules, no regulations, free markets, and free trade. But now is the time for real change.

    Full Text Available Diplopia means seeing two images of the same, one object. It is a symptom with numerous causes that can involve many different structures. The cause can lay in the eyeball itself: the cornea, the lens and the retina or behind the eyeball: in the orbit or intracranial. Diplopia is only a symptom that can indicate a life threatening ilness like an aneurysm, a dissection or a brain tumor. That is why when presented with it we have to do a thorough examination and look for a red flag that could indicate danger. This way we can make a timely intervention, saving the patients sight or life. This article describes the most crucial signs of a dangerous underlying condition that we cannot afford to miss, a practical guide to the historical assesment, as well as to the physical examination of a patient with double vision to help localize the cause.

  6. A Contribution Towards A Grammar of Code

    Directory of Open Access Journals (Sweden)

    David M. Berry

    2008-01-01

    Full Text Available Over the past thirty years there has been an increasing interest in the social and cultural implications of digital technologies and ‘informationalism’ from the social sciences and humanities. Generally this has concentrated on the implications of the “convergence” of digital devices and services, understood as linked to the discrete processing capabilities of computers, which rely on logical operations, binary processing and symbolic representation. In this paper, I wish to suggest that a ‘grammar of code’ might provide a useful way of thinking about the way in which digital technologies operate as a medium and can contribute usefully to this wider debate. I am interested in the way in which the dynamic properties of code can be understood as operating according to a grammar reflected in its materialisation and operation in the lifeworld – the discretisation of the phenomenal world. As part of that contribution in this paper I develop some tentative Weberian ‘ideal-types’. These ideal-types are then applied to the work of the Japanese composer, Masahiro Miwa, whose innovative ‘Reverse-Simulation music’ models the operation of basic low-level digital circuitry for the performance and generation of musical pieces.

  15. A Boy with a Large Bladder Stone

    Directory of Open Access Journals (Sweden)

    Kuo-Shen Chow

    2008-08-01

    Full Text Available Despite the frequent association of urinary tract infection with vesicoureteral reflux and urinary calculi, since vesicouretal reflux is induced by bladder stones, the coexistence of vesicoureteral reflux and bladder stones is rare. Because of its occurrence in children belonging to poor socioeconomic groups, it is believed to be a deficiency disorder. Most cases of bladder stones occur between the ages of 2 and 5 years. Common clinical presentations of bladder stones include urinary dribbling and enuresis, frequency of micturition, pain during micturition, pelvic pain and hematuria. We report the occurrence of a large bladder stone in a boy, who experienced intermittent lower abdominal pain and urinary incontinence, both during the day and at night. He had been diagnosed with enuresis and treated in pediatric clinics for 1 year. Delayed diagnosis resulted in bladder stone formation. The stone was larger than 2.5 cm and open vesicolithotomy was therefore selected as the best and safest treatment choice. His symptoms disappeared after surgery. Thorough metabolic and environmental evaluations of such cases are required on an individual basis. Bladder stones should be considered as a possible diagnosis in children presenting with urinary incontinence.

  16. Consciousness Is a Thing, Not a Process

    Directory of Open Access Journals (Sweden)

    Full Text Available The central dogma of cognitive psychology is ‘consciousness is a process, not a thing’. Hence, the main task of cognitive neuroscientists is generally seen as working out what kinds of neural processing are conscious and what kinds are not. I argue here that the central dogma is simply wrong. All neural processing is unconscious. The illusion that some of it is conscious results largely from a failure to separate consciousness per se from a number of unconscious processes that normally accompany it—most particularly focal attention. Conscious sensory experiences are not processes at all. They are things: specifically, spatial electromagnetic (EM patterns, which are presently generated only by ongoing unconscious processing at certain times and places in the mammalian brain, but which in principle could be generated by hardware rather than wetware. The neurophysiological mechanisms by which putatively conscious EM patterns are generated, the features that may distinguish conscious from unconscious patterns, the general principles that distinguish the conscious patterns of different sensory modalities and the general features that distinguish the conscious patterns of different experiences within any given sensory modality are all described. Suggestions for further development of this paradigm are provided.

    Nonlinear charge transport in superconductor-insulator-superconductor (SIS) Josephson junctions has a unique signature in the shuttled charge quantum between the two superconductors. In the zero-bias limit Cooper pairs, each with twice the electron charge, carry the Josephson current. An applied bias VSD leads to multiple Andreev reflections (MAR), which in the limit of weak tunneling probability should lead to integer multiples of the electron charge ne traversing the junction, with n integer larger than 2Δ/eVSD and Δ the superconducting order parameter. Exceptionally, just above the gap eVSD ≥ 2Δ, with Andreev reflections suppressed, one would expect the current to be carried by partitioned quasiparticles, each with energy-dependent charge, being a superposition of an electron and a hole. Using shot-noise measurements in an SIS junction induced in an InAs nanowire (with noise proportional to the partitioned charge), we first observed quantization of the partitioned charge q = e*/e = n, with n = 1-4, thus reaffirming the validity of our charge interpretation. Concentrating next on the bias region eVSD ~ 2Δ, we found a reproducible and clear dip in the extracted charge to q ~ 0.6, which, after excluding other possibilities, we attribute to the partitioned quasiparticle charge. Such dip is supported by numerical simulations of our SIS structure.

  7. A vision for a continental energy strategy

    Klein, R.; Tobin, B.; Angevine, G.; Fryer, K.; Martin, L.T.

    2008-01-01

    This paper presented a vision with respect to a continental energy strategy and the principles and goals that must underlie such a strategy. These principles include relying on signals emanating from energy markets to guide investment; limiting the role of government to that of ensuring that the policy and institutional framework is conducive to the development and operation of competitive and innovative energy markets; and ensuring free and open energy trade in energy commodities, both within the continent and with the rest of the world. The paper also identified a number of important factors that, would shape and condition continental energy development and trade. The paper provided an overview of the North American energy use and supply situation for the following resources: oil; natural gas; electricity; coal; nuclear power; hydroelectricity; geothermal energy; wind power; solar power; and ethanol. It also discussed the contribution of the North American Free Trade Agreement (NAFTA) through increased natural gas exports. It was concluded that given the petroleum resources of the three countries and their increased value because of higher oil and gas prices, there was considerable incentive for Canada, the United States, and Mexico to streamline regulations in order to facilitate the efficient development, transportation, and use of the continent's energy resources in accordance with market conditions. 38 refs., 2 tabs., 21 figs

  15. Multitasking as a choice: a perspective.

    Broeker, Laura; Liepelt, Roman; Poljac, Edita; Künzell, Stefan; Ewolds, Harald; de Oliveira, Rita F; Raab, Markus

    2018-01-01

    Performance decrements in multitasking have been explained by limitations in cognitive capacity, either modelled as static structural bottlenecks or as the scarcity of overall cognitive resources that prevent humans, or at least restrict them, from processing two tasks at the same time. However, recent research has shown that individual differences, flexible resource allocation, and prioritization of tasks cannot be fully explained by these accounts. We argue that understanding human multitasking as a choice and examining multitasking performance from the perspective of judgment and decision-making (JDM), may complement current dual-task theories. We outline two prominent theories from the area of JDM, namely Simple Heuristics and the Decision Field Theory, and adapt these theories to multitasking research. Here, we explain how computational modelling techniques and decision-making parameters used in JDM may provide a benefit to understanding multitasking costs and argue that these techniques and parameters have the potential to predict multitasking behavior in general, and also individual differences in behavior. Finally, we present the one-reason choice metaphor to explain a flexible use of limited capacity as well as changes in serial and parallel task processing. Based on this newly combined approach, we outline a concrete interdisciplinary future research program that we think will help to further develop multitasking research.

  3. Geogas - a carrier or a tracer

    International Nuclear Information System (INIS)

    Hermansson, H.P.; Chyssler, J.; Aakerblom, G.; Linden, A.

    1991-10-01

    This report contains an account and discussion of the results of work published within the area of geogas, with particular emphasis on the conditions which would exist in a Swedish repository for spent nuclear fuel. The following issues are addressed. Is there any evidence/is it probable or improbable that a geogas flow exists? How does the flow move, what does it consists of and at what depth is it released? Is there any evidence/is it probable that matter is transported to the surface by geogas flow? What are the mechanisms that could be involved in the transport of matter by geogas? Does the composition of the gas have any bearing on the ability of the gas to transport matter? Would the gas tend to transport certain elements rather than others? What effect does the surrounding rock have on gas transport? If matter is transported upwards by geogas, is this kind of transport important compared to other means of transport of matter? The conclusion of this report is that all evidence points to the existence of a geogas flow and that nitrogen seems to be the most probable geogas candidate in a Swedish repository environment. It is difficult to estimate how quickly the gas can reach the surface from a depth of 500 m. The extreme values are 30 minutes to several thousand years. It is likely that matter is transported by geogas. Such transport is likely to be selective in a way that would favour the upward transport of colloids and other smaller particles. The most probable mechanisms is transport by ascending gas bubbles in water-filled fractures/cavities. Estimates of times, transport rates and quantities in this report are speculative and uncertain and must be regarded as an initial effort, since little or nothing is known of much of the necessary background data. For this reason, it is impossible to compare the importance of geogas transport of radionuclides from a repository with other transport mechanisms. (65 refs., 4 figs., 6 tabls.)

  4. Eph receptor A10 has a potential as a target for a prostate cancer therapy

    Highlights: • EphA10 mRNA is overexpressed in breast, prostate and colon cancer cell lines. • EphA10 is overexpressed in clinical prostate tumors at mRNA and protein levels. • Anti-EphA10 antibodies were cytotoxic on EphA10-positive prostate cancer cells. - Abstract: We recently identified Eph receptor A10 (EphA10) as a novel breast cancer-specific protein. Moreover, we also showed that an in-house developed anti-EphA10 monoclonal antibody (mAb) significantly inhibited proliferation of breast cancer cells, suggesting EphA10 as a promising target for breast cancer therapy. However, the only other known report for EphA10 was its expression in the testis at the mRNA level. Therefore, the potency of EphA10 as a drug target against cancers other than the breast is not known. The expression of EphA10 in a wide variety of cancer cells was studied and the potential of EphA10 as a drug target was evaluated. Screening of EphA10 mRNA expression showed that EphA10 was overexpressed in breast cancer cell lines as well as in prostate and colon cancer cell lines. Thus, we focused on prostate cancers in which EphA10 expression was equivalent to that in breast cancers. As a result, EphA10 expression was clearly shown in clinical prostate tumor tissues as well as in cell lines at the mRNA and protein levels. In order to evaluate the potential of EphA10 as a drug target, we analyzed complement-dependent cytotoxicity effects of anti-EphA10 mAb and found that significant cytotoxicity was mediated by the expression of EphA10. Therefore, the idea was conceived that the overexpression of EphA10 in prostate cancers might have a potential as a target for prostate cancer therapy, and formed the basis for the studies reported here

    The national legislation and the IAEA's Basic Safety Standards Series require the implementation of a QA programme for approval of dosimetry services. The implementation of a quality system according to EN ISO/IEC17025:2005 standard is a way to demonstrate that the dosimetry service is technically competent and capable of generating technically valid results. There are around fifty different standards relevant to individual monitoring, which indicates the complexity and difficulty of understanding and using the appropriate standard in routine work. The new recommendations published by European Commission - RP-160 - bring together requirements and guidance given in 96/29/EURATOM Directive, ICRP Publications, ICRU Reports and IAEA technical documents. The aim of these recommendations is to address the growing need for improvement and harmonization of practices and procedures used in individual dosimetry, for a mutual recognition of dose assessments performed by Approved Dosimetry Services across Europe. An intercomparison exercise among dosimetry services is like a performance test. The results of intercomparisons are published but anonimized. In many Member States participation in international intercomparisons is strongly recommended as results can be used to support an application for approval or accreditation. In this paper we present the results of our participation in two intercomparison exercises: EURADOS Intercomparison 2008 and EURADOS Intercomparison 2010. The results are displayed using the 'trumpet curves' (ISO 14146). The corrective actions are presented and also the lessons learned. At first exercise, in 2008, we have participated with one dosimetric system - photographic dosemeter - and at the second one, we have participated with two dosimetric systems: photographic and thermoluminescent.

  6. A cautious approach to a new market

    As companies like Shell (London), Total (Paris), and Norsk Hydro (Oslo) spearhead the push into developing Vietnam's largely untapped oil and gas reserves, chemical firms are carefully monitoring events. Some already have fledgling operations there - ICI (London), for example, has established activities covering paints, titanium dioxide, and explosives. But most are waiting for others to go in first, says Patrick Looram, senior associate and director/Southeast Asia with Technomic Consultants, speaking at CW's 1993 Asia/Pacific Chemical Industry conference in Singapore. Describing Vietnam, with its 70-million population, as the 'last great Asian market,' Looram says the most important industries for the chemicals sector in the shorter terms are likely to include textiles, packaging, plastics, food and agriculture, and pharmaceuticals. But he notes the country's chemicals requirements are still at a very early stage, with 1992 plastics demand, for example, put at less than 100,000 m.t. Basic infrastructure requirements are put at $30 billion-$40 billion. Vietnam has a range of measures in place to establish a market economy, such as decentralized control over industry, freeing up of price controls, and liberal foreign investment laws. Fewer than 1,000 of Vietnam's 12,000-plus state enterprises are owned by national government; control is in the hands of the provinces and municipalities. But to get results, Looram says it is necessary to deal directly with plants. Many of these operations, however, are nearly insolvent, and Looram says about a third are expected to close over the next couple of years. The strength of other Asian economies is crucial to Vietnam's development, Looram says, while a lifting of the US embargo on vietnam will play an important role

  7. A Simple Spectral Observer

    Directory of Open Access Journals (Sweden)

    Lizeth Torres

    2018-05-01

    Full Text Available The principal aim of a spectral observer is twofold: the reconstruction of a signal of time via state estimation and the decomposition of such a signal into the frequencies that make it up. A spectral observer can be catalogued as an online algorithm for time-frequency analysis because is a method that can compute on the fly the Fourier transform (FT of a signal, without having the entire signal available from the start. In this regard, this paper presents a novel spectral observer with an adjustable constant gain for reconstructing a given signal by means of the recursive identification of the coefficients of a Fourier series. The reconstruction or estimation of a signal in the context of this work means to find the coefficients of a linear combination of sines a cosines that fits a signal such that it can be reproduced. The design procedure of the spectral observer is presented along with the following applications: (1 the reconstruction of a simple periodical signal, (2 the approximation of both a square and a triangular signal, (3 the edge detection in signals by using the Fourier coefficients, (4 the fitting of the historical Bitcoin market data from 1 December 2014 to 8 January 2018 and (5 the estimation of a input force acting upon a Duffing oscillator. To round out this paper, we present a detailed discussion about the results of the applications as well as a comparative analysis of the proposed spectral observer vis-à-vis the Short Time Fourier Transform (STFT, which is a well-known method for time-frequency analysis.

    In a given path with multiple branches, in principle, it can be expected that there are some fork points, where one branch is bifurcated into different branches, or various branches converge into one or several branches. In this paper, it is shown that if there is a web formed by such branches in a given field space, in which each branch can be responsible for a period of slow roll inflation, a multiverse separated by a domain wall network will come into being, some of which might correspond to our observable universe. We discuss this scenario and show possible observations of a given observer at late time.

    We present a simple sandwich gravitational wave of the Robinson-Trautman family. This is interpreted as representing a shock wave with a spherical wavefront which propagates into a Minkowski background minus a wedge (i.e. the background contains a cosmic string). The deficit angle (the tension) of the string decreases through the gravitational wave, which then ceases. This leaves an expanding spherical region of Minkowski space behind it. The decay of the cosmic string over a finite interval of retarded time may be considered to generate the gravitational wave. (letter to the editor)

    Over half a century ago, a Canadian judge defined a profession in a way that resonates still today, not only for lawyers and doctors, but for the current wide variety of professions and professionals. This article is a reflection on this definition. It briefly considers the historical context within which the knowledge base that characterises a profession evolved and what the various component parts of the judge's definition entail. A final consideration goes beyond the terms of the definition proposed--that of our ethical responsibility as professionals to stand up and be counted and, in the context of the disorder around us, to speak out.

    A self-contained instrument for the measurement of magnetic fields is described which consists of a command module and a thermally stabilized Hall plate mounted in a probe. The command module contains the circuitry for the temperature stabilization and the current source for the probe, an analog-to-digital converter and a microprocessor-based control circuitry for the command of the measuring sequences. A read-only memory contains a calibration table for the relation between Hall voltage and magnetic field. The measured field strength can be directly displayed in units of induction (tesla). The teslameter is provided with a serial teletype input-output port for remote control. An addressing scheme allows up to 16 modules to be connected in parallel and to be controlled via a single teletype channel. This is especially useful if several teslameters are used in a complex measuring set-up. (Auth.)

    A system for performing radiographic examination, particularly of large items such as international container units is disclosed. The system is formed as an installation comprising housings for respective linear accelerators transmitting a beam of radiation across the path of a conveyor along which the units can be displaced continuously or incrementally. On either end of the installation are container handling areas including roller conveyors with drag chains and transverse manipulators, and the whole installation is secured within automatically operated doors which seal the high energy region when a container on the conveyor is being subjected to examination. The radiation transmitted through a container is detected in a detector system incorporating a fluoroscopic screen light output from which is detected in a camera system such as a television camera, and transmitted as coded pulsed signals by a coding transfer unit to display screens where an image of the transmitted information can be displayed and/or recorded for further use.

    1967-01-01

    If a reservoir is fed from a single source, which may not always be pure, the extent to which the inflowing stream mixes with the water in the reservoir is important for the quality of the water supplied by the reservoir. This question was investigated at the Lingese Reservoir, containing between one and two million cubic metres of water, in the Bergisches Land (North Rhine-Westphalia). The investigation was carried out at four different seasons so that the varying effects of the stream-water temperatures could be studied in relation to the temperature of the reservoir water. The stream was radioactively labelled at the point of inflow into the reservoir, and its flow through the reservoir was measured in length and depth from boats, by means of 1-m-long Geiger counters. In two cases the radioactivity of the outflowing water was also measured at fixed points. A considerable variety of intermixing phenomena were observed; these were mainly of limnological interest. The results of four experiments corresponding to the four different seasons are described in detail. They were as follows: (1) The mid-October experiment where the stream, with a temperature of 8.0 deg. C, was a good 5 deg. C colder than the water of the reservoir, whose temperature was almost uniform, ranging from 13.2 deg. C at the bed to 13.6 deg. C at the surface. (2) The spring experiment (second half of March), when the stream temperature was only 0.3 deg. C below that of the reservoir surface (7.8 deg. C), while the temperature of the bed was 5.8 deg. C. (3) The winter experiment (early December) where at first the temperature of the stream was approximately the same as that of the surface so that, once again, the stream at first flowed 1/2 - 1 m below the surface. During the almost wind-free night a sudden fall in temperature occurred, and the air temperature dropped from 0 deg. C to -12 deg. C. (4) The summer experiment (end of July to mid-August) when the stream was nearly 1 deg. C colder than

    In the poem "Always", the author Pablo Neruda employs the first person narration to incisively reveal the paradoxical traits in human nature by exploring man in relation to love. "I" play a role shifting from a calm narrator to a furious one, and the last recovering to a mild one, which offers a multiple visual angle to observe humanity. In sum, by means of continuous changes of my inner feelings in the poem, Pablo Neruda reveals the paradoxical humanity .

    Full Text Available With the ageing of nuclear facilities or the reduced interest in their further operation, a new set of problems, related to the decommissioning of these facilities, has come into forefront. In many cases it turns out that the preparations for decommissioning have come too late, and that financial resources for covering decommissioning activities have not been provided. To avoid such problems, future liailities should be thoroughly estimated in drawing up the decommissioning and waste management programme for each nuclear facility in time, and financial provisions for implementing such programme should be provided. In this paper a presentation of current decommissioning experience in Slovenia is given. The main problems and difficulties in decommissioning of the Žirovski Vrh Uranium Mine are exposed and the lesson learned from this case is presented. The preparation of the decommissioning programme for the Nuclear Power Plant Krško is also described, and the situation at the TRIGA research reactor is briefly discussed.

    Case reports describe patient cases which are of particular interest due to their novelty and their potential message for clinical practice. While there are several types of case reports, originality and clinical implications constitute the main virtues by which case reports are judged. Defining the educational message and choosing the right audience are vital steps in the process of writing. Generally, a case report is structured, its main components being the abstract, the introduction, the case description and the discussion. Guidelines and tips for writing case reports are not enough for making a successful author, but they help, especially less experienced doctors, to exercise and improve their writing. If properly prepared, case reports can still communicate new observations in an interesting and pleasant way, thereby enriching our knowledge, even in the era of evidence-based medicine.

    Is the field of pediatrics doing all that it can for the health of children? Many think that the field has gone off track and that we could do better. These articles highlight some different ways of judging the successes and failures of pediatrics in the United States today. The choices that we face are stark. To change the system, we would need to recalibrate the balance between utilitarian approaches to resource allocation, such as might be dictated by cost-effectiveness analyses, and deontologic approaches that prioritize unbreakable commitments or promises to individuals. These changes would entail large-scale social engineering projects to reshape our health care system, our educational system, and our public health system. A failure to change, however, might perpetuate a system that is not doing all it can for the health of America's children and the society they will form.

For instance, in randomized trials tuberculosis and measles vaccines are associated...... with a substantial reduction in overall child mortality, which cannot be explained by prevention of the target disease. New research suggests that the nonspecific effects of vaccines are related to cross-reactivity of the adaptive immune system with unrelated pathogens, and to training of the innate immune system...... through epigenetic reprogramming.

    2003-12-01

    Most brands don't make much money. Year after year, businesses generate 80% to 90% of their profits from less than 20% of their brands. Yet most companies tend to ignore loss-making brands, unaware of the hidden costs they incur. That's because executives believe it's easy to erase a brand; they have only to stop investing in it, they assume, and it will die a natural death. But they're wrong. When companies drop brands clumsily, they antagonize loyal customers: Research shows that seven times out of eight, when firms merge two brands, the market share of the new brand never reaches the combined share of the two original ones. It doesn't have to be that way. Smart companies use a four-step process to kill brands methodically. First, CEOs make the case for rationalization by getting groups of senior executives to conduct joint audits of the brand portfolio. These audits make the need to prune brands apparent throughout the organization. In the next stage, executives need to decide how many brands will be retained, which they do either by setting broad parameters that all brands must meet or by identifying the brands they need in order to cater to all the customer segments in their markets. Third, executives must dispose of the brands they've decided to drop, deciding in each case whether it is appropriate to merge, sell, milk, or just eliminate the brand outright. Finally, it's critical that executives invest the resources they've freed to grow the brands they've retained. Done right, dropping brands will result in a company poised for new growth from the source where it's likely to be found--its profitable brands.

    2007-09-01

    Regenerative medicine and in vivo biosensor applications require the formation of mature vascular networks for long-term success. This study investigated whether biodegradable porous membranes could induce the formation of a vascularized fibrous capsule and, if so, the effect of degradation kinetics on neovascularization. Poly(l-lactic acid) (PLLA) and poly(dl-lactic-co-glycolic) acid (PLGA) membranes were created by a solvent casting/salt leaching method. Specifically, PLLA, PLGA 75:25 and PLGA 50:50 polymers were used to vary degradation kinetics. The membranes were designed to have an average 60mum pore diameter, as this pore size has been shown to be optimal for inducing blood vessel formation around nondegradable polymer materials. Membrane samples were imaged by scanning electron microscopy at several time points during in vitro degradation to assess any changes in pore structure. The in vivo performance of the membranes was assessed in Sprague-Dawley rats by measuring vascularization within the fibrous capsule that forms adjacent to implants. The vascular density within 100microm of the membranes was compared with that seen in normal tissue, and to that surrounding the commercially available vascularizing membrane TheraCyte. The hemoglobin content of tissue containing the membranes was measured by four-dimensional elastic light scattering as a novel method to assess tissue perfusion. Results from this study show that slow-degrading membranes induce greater amounts of neovascularization and a thinner fibrous capsule relative to fast degrading membranes. These results may be due both to an initially increased number of macrophages surrounding the slower degrading membranes and to the maintenance of their initial pore structure.

It is the reaction appears in the minds of the people when they hear or see a name or symbol of someuniversity or institute. This research aimed to identify key factors that are required to be taken care of while developing university branding strategy. For this research a deductive approach is adopted, as the main objective of this research is to investigate the influenceof attributes like awareness, acceptance, and quality on brand image of universities, therefore, it is proposed to conduct semi structured interviews which are considered to be a most suitable for testing of influence of different attributes on brand image. The components used in the study are awareness, acceptance, prestige, incentives and quality. The result of the study shows that in the university selection decision, image of the university is the key determinant. The result also shows that the image of the university has four key constructing factors which are quality, prestige, financial incentives, and acceptance. Quality is found to be the strongest construct followed by prestige, acceptance and incentives.

Scientists generally ignore the laws of nature because they “are what they are” and because visualizing different laws of nature challenges the imagination. This article defines a conceptual model separating space (laws of nature from the universe’s energy source (initial conditions and expansion (big bang. By considering the ramifications of changing the laws of nature, initial condition parameters, and two variables in the big bang theory, the model demonstrates that traditional fine tuning is not the whole story when creating a universe. Supporting the model, space and “nothing” are related to the laws of nature, mathematics and multiverse possibilities. Speculation on the beginning of time completes the model.

  8. A road safety course with a difference!

    CERN Document Server

    2008-01-01

    Are you feeling brave? Then why not sign up for a road safety session. 10 to 14 November is road safety week at CERN and the Touring Club Suisse (TCS) will be in the Main Building, 500, with several hair-raising activities to try. If you walk into the foyer of building 500 between 10 and 14 November you might, at first glance, think that you have walked into a fairground. But the machines designed to spin you upside down and slide you also are actually part of CERN’s road safety week. Every day during the week there will six sessions each lasting about an hour where you can try out a series of exhilarating activities. If you are feeling brave enough you could try and get yourself out of the crash simulator. Not as easy as it sounds - after being spun over several times you can experience what it’s like to try and escape from an overturned car - dangling upside down attached only by your seatbelt! During the course instructors from the Touring Club Suisse (TC...

  9. JERUSALEM: A TALE OF A CITY

    Directory of Open Access Journals (Sweden)

    M. Alaa Mandour

    2012-04-01

    Full Text Available World class cities are few and far between, sometimes referred to as ‘global cities’ or simply ‘world cities’. There are no more than a dozen metropolitan areas in the world that can claim  this kind of global status. London,  New  York,  Paris,  and  Tokyo  sit  at  the  top  of  this  world  city  hierarchy. They  have  enormous concentrations of economic, political, and cultural clout – measured by such things as the number of corporate headquarters, the size of their stock exchanges, the presence of national and international political bodies, and their role in music, fashion, and other cultural activities. What would it take to make a city claimed by two nations and central to three religions “merely” a city, a place of difference and diversity in which contending ideas and citizenries can co-exist in benign yet creative ways? The intractable conflicts in the Middle East and the cycle of violence among Israelis and Palestinians are deeply embedded in historical struggles over national sovereignty and the right to territory. For this reason, questions about whose state will prevail in what physical location have defined the terms of conflict and negotiation. This also has meant that most proposed solutions to  “the  Middle  East  problem”  have  revolved  around  competing  claims  of  nation-states,  their  rights  to existence, and their physical and juridically-sanctioned relationships to each other. While true generally, this framing of the problem has been especially dominant in the case of Jerusalem, a city that is geographically and historically an overlay of spaces and artifacts that carry deep meaning for competing peoples and nations. The current struggles of Palestinians and Israelis to each claim this hallowed ground as their capital city has added yet another layer of complexity, conflict, and political division, all of which is reflected in the competing/dual nomenclature Al

  10. A Motionless Camera

    Science.gov (United States)

    1994-01-01

    Omniview, a motionless, noiseless, exceptionally versatile camera was developed for NASA as a receiving device for guiding space robots. The system can see in one direction and provide as many as four views simultaneously. Developed by Omniview, Inc. (formerly TRI) under a NASA Small Business Innovation Research (SBIR) grant, the system's image transformation electronics produce a real-time image from anywhere within a hemispherical field. Lens distortion is removed, and a corrected "flat" view appears on a monitor. Key elements are a high resolution charge coupled device (CCD), image correction circuitry and a microcomputer for image processing. The system can be adapted to existing installations. Applications include security and surveillance, teleconferencing, imaging, virtual reality, broadcast video and military operations. Omniview technology is now called IPIX. The company was founded in 1986 as TeleRobotics International, became Omniview in 1995, and changed its name to Interactive Pictures Corporation in 1997.

    Full Text Available This article examines how the preschool child is enabled to withdraw from the peer group and create a private, individual space within the institutional collective. The question under consideration is, “What factors are necessary to enable a child to create and maintain a withdrawal space in the preschool?” Data were collected through ethnographic fieldwork at two Montessori schools in the south of Sweden. Analysis of the results reveals that a child is enabled through a combination of two elements: a level of opportunity to create a space and a level of defense of a created space. These two factors are dependent on the teachers’ ability to correctly identify space creation, alongside their desire for the child’s space creation effort to be successful.

    1974-01-01

    Between the steel pressure vessel of the pressurized water power reactor and the biological shield a gap is found which enables inspections as well as cooling by air or gas. Within the gap, fins are equally distributed around the circumference of the pressure vessel summing parallel to each other and to the longitudinal axis of the vessel or being inclined. The fins cross the gap for about 9/10. Each fin consists of a sectional bar supported with its foot on a girder. The girder has got a rectangular steel section of two sectional iron parts. Between one of the parts and a plate anchored in the biological shield a ceramic body is inserted as a heat insulation. A further heat insulation of aluminium foils connects the fins with each other and divides the gap into two concentric subspaces which can be streamed through by a gas having different temperatures.

    2018-01-01

    A noncommutative algebra corresponding to the classical catenoid is introduced together with a differential calculus of derivations. We prove that there exists a unique metric and torsion-free connection that is compatible with the complex structure, and the curvature is explicitly calculated. A noncommutative analogue of the fact that the catenoid is a minimal surface is studied by constructing a Laplace operator from the connection and showing that the embedding coordinates are harmonic. Furthermore, an integral is defined and the total curvature is computed. Finally, classes of left and right modules are introduced together with constant curvature connections, and bimodule compatibility conditions are discussed in detail.

    1976-11-01

    There are major differences between a lecture and a paper for publication. Often the printed word is spoken at meetings, a kind of compulsive public reading which has robbed the lecturer of the chance of oratory and the audience of a little enjoyment. The simple fact is that although doctors read aloud badly (actors do this far better) most can learn to speak spontaneolsly and with animation; but this requires time and effort, both of which are donated in a miserly way. The successful lecturer is generous and considerate of his audience--a rare being at medical meetings.

    A spider elevator is proposed which contains a body, a wedge clamp with wedges hinged to each other, a subassembly for holding the wedge clamp in the open and closed positions and a mechanism for changing the wedge clamp, which is made in the form of levers with ears for cleats and installed in the body with the capability of turning. To increase reliability in the operational mode through using the external force for clamping the pipe, the free ends of the levers are hinged with the body by a power cylinder.

    A technical note is a short article giving a brief description of a specific development, technique or procedure, or it may describe a modification of an existing technique, procedure or device applicable to medicine. The technique, procedure or device described should have practical value and should contribute to clinical diagnosis or management. It could also present a software tool, or an experimental or computational method. Technical notes are variously referred to as technical innovations or technical developments. The main criteria for publication will be the novelty of concepts involved, the validity of the technique and its potential for clinical applications.

    A website is a window to the outside world. For a dental practice, it may be the first point of contact for a prospective new patient and will therefore provide them with their 'first impression'; this may be days or weeks before actually visiting the practice. This section considers the different ways of creating a dental practice website and lists some of the main dental website design companies. It also describes what factors make a successful website and offers advice on how to ensure that it complies with current regulations and recommendations.

    1983-01-01

    The paper describes a calorimeter which is used to determine the particle flux of an accelerator. It incorporates as its principal feature a Peltier module which is operated in a constant current pulse mode. Via a feedback arrangement, the Peltier module thermally compensates the heat generated by the particle beam by supplying discrete 'cooling quanta'. The number of 'quanta' generated per unit time is measured with a frequency counter and is proportional to the beam power. The calorimeter can be calibrated via internal resistors which dissipate a precisely known amount of power in the target. (orig.)

    To analyze the concept of stress and provide an operational definition of stress. Literature review revealed that stress is a commonly used, but often ambiguous, term. Findings supported a definition of stress entailing an individual's perception of a stimulus as overwhelming, which in turn elicits a measurable response resulting in a transformed state. This analysis adopts a dynamic definition of stress that may serve to encourage communication, promote reflection, and enhance concept understanding. This definition may provide direction for future work, as well as enhance efforts to serve patients affected by stress. © 2013 Wiley Periodicals, Inc.

    A readily transportable device of relative light weight comprising a pair of tensioned guides for providing accurate and stable reference planes. An embodiment comprises a pair of rods or guides in tension between a pair of end members, the end members being spaced apart by a pair of arcuate compression members. The tensioned guides provide planes of reference for measuring devices moved therealong adjacent to a component to be measured. The device is especially useful for making on-site dimensional measurements of components, such as irradiated and therefore radioactive components, that cannot readily be transported to an inspection laboratory.

    2015-10-01

    Full Text Available The severity and longevity of the recession caused by the 2007 financial crisis has highlighted the lack of a reliable macro-based financial regulation framework. As a consequence, addressing the link between the stability of the financial system as a whole and the performance of the overall economy has become a mandate for policymakers and scholars. Many countries have adopted macroprudential tools as policy responses for safeguarding the financial system. This paper provides a literature review of macroprudential policies, its objectives and the challenges that a macro-based framework needs to overcome, such as financial stability, procyclicality, and systemic risk.

    Presentation is made of a drilling rig tower, comprising a gantry, a support shaft with a bracing strut and drawings out, and turn buckles. In order to increase the reliability of the tower in operation, to decrease the over all dimensions in a transport position, and to decrease the amount of time taken to transfer the tower from an operational position into a transportable one, and vice versa, the tower is equipped with a rotary frame made in the form of a triangular prism, whose lateral edges are connected by hinges: the first one with the lower part of the support shaft, the second with the gantry, and the third one to the upper part of the support shaft by means of the drawings out. The large boundary of the rotary frame is connected by a hinge to the support shaft by means of a bracing strut, which is equipped with a slide block connected to it by a hinge, and the rotary frame has a guide for the slide block reinforced to it on the large boundary. Besides this, the lateral edge of the rotary frame is connected to the gantry by means of turn buckles.

    1980-01-01

    A description is presented of a radioimmunoassay designed to prove the presence of the antibody against the hepatitis A virus (HA Ab, anti-Ha) using an Abbott HAVAB set. This proof as well as the proof of the antibody against the nucleus of the hepatitis B virus is based on competition between a normal antibody against hepatitis A virus and a 125 I-labelled antibody for the binding sites of a specific antigen spread all over the surface of a tiny ball; this is then indirect proof of the antibody under investigation. The method is described of reading the results from the number of impulses per 60 seconds: the higher the titre of the antibody against the hepatitis A virus in the serum examined, the lower the activity of the specimen concerned. The rate is reported of incidence of the antibody against the hepatitis A virus in a total of 68 convalescents after hepatitis A; the antibody was found in 94.1%. The immunoglobulin made from the convalescents' plasma showed the presence of antibodies in dilutions as high as 1:250 000 while the comparable ratio for normal immunoglobulin Norga was only 1:2500. Differences are discussed in the time incidence of the antibodies against the hepatitis A virus, the antibodies against the surface antigen of hepatitis B, and the antibody against the nucleus of the hepatitis V virus.

  13. What makes a movement a gesture?

    Science.gov (United States)

    Novack, Miriam A; Wakefield, Elizabeth M; Goldin-Meadow, Susan

    2016-01-01

    Theories of how adults interpret the actions of others have focused on the goals and intentions of actors engaged in object-directed actions. Recent research has challenged this assumption, and shown that movements are often interpreted as being for their own sake (Schachner & Carey, 2013). Here we postulate a third interpretation of movement-movement that represents action, but does not literally act on objects in the world. These movements are gestures. In this paper, we describe a framework for predicting when movements are likely to be seen as representations. In Study 1, adults described one of three scenes: (1) an actor moving objects, (2) an actor moving her hands in the presence of objects (but not touching them) or (3) an actor moving her hands in the absence of objects. Participants systematically described the movements as depicting an object-directed action when the actor moved objects, and favored describing the movements as depicting movement for its own sake when the actor produced the same movements in the absence of objects. However, participants favored describing the movements as representations when the actor produced the movements near, but not on, the objects. Study 2 explored two additional features-the form of an actor's hands and the presence of speech-like sounds-to test the effect of context on observers' classification of movement as representational. When movements are seen as representations, they have the power to influence communication, learning, and cognition in ways that movement for its own sake does not. By incorporating representational gesture into our framework for movement analysis, we take an important step towards developing a more cohesive understanding of action-interpretation.

Tal evidencia se extiende hasta tiempos prehispánicos con hongos piedra, códices y crónicas. Actualmente se tiene conocimiento de 134 especies comestibles —ya sean para autoconsumo o venta— y alrededor de 40 hongos medicinales en la región. Asociados con estos usos, existen conocimientos morfológicos, fenológicos, ecológicos y culinarios de los hongos, así como desarrollados esquemas de nomenclatura y clasificación, el reconocimiento de 36 especies consideradas tóxicas y la presencia de hongos en diferentes narrativas. APPROACHES TO MAYAN ETHNOMYCOLOGY The Mayan peoples inhabit a biologically megadiverse region and have traditionally made a diversified use of their resources. Ethnomycology —the discipline that studies the relationship between human groups and mushrooms— provides extensive evidence of the knowledge these ethnic groups have of mushrooms and their use. Evidence can be traced back to pre-Hispanic times with mushrooms carved in stone and their presence in codices and chronicles. In the region, 134 edible species —either for consumption or for trade— are currently known, as well as about 40 medicinal mushrooms. Morphological, phenological, ecological and culinary data as well as nomenclature and classification schemes are associated with these uses. The identification of 36 species considered toxic and the presence of mushrooms in different narratives is also part of this body of knowledge.

Developing new attitudes and skills for learning is necessary in a school immersed in the information society, which we want to become the knowledge society. The students must learn to develop their autonomy and responsibility in an open world where there are a lot of information and stimuli. In this context, it’s necessary the student to become a “strategic learner”, an autonomous person who wants to learn to grow for himself and for other people, with reference to values; someone who learns to mobilize, observe, assess, plan and control their own learning processes. We’re talking about self-regulated learning, about "learning to learn". And, although it’s true that the school has lost its key role in the transmission of information, it is also true that the school becomes a privileged place to teach learning to learn. The self-regulation, the critical thinking, the civic commitment, etc. have to settle in the school to continue growing, and they can be taught and must be taught from an early age. In this work we enclose some clues for the development of strategic learning in the educational system.

    Omalizumab, a monoclonal antibody against IgE, may be effective on nasal polyps, but its use is not currently authorized to treat that disease. We report the cases of three patients who were given omalizumab for asthma after undergoing nasal surgical polypectomy. Although such procedure is frequently followed by polyp recurrence, none of the three patients developed this complication, and in one subject the regression of initial polyp return was registered after starting omalizumab. Our data support the hypothesis that omalizumab may be useful to treat nasal polyposis.
