    2000-01-01

    In this paper I compare and contrast the alternative treatments of the Other as they appear first in the radical geography of 1968, then in the political geography of 1998. While in the Hegelian sixties both the master and the slave recognized that they are defined in terms of each other (a = b), the politically correct of the nineties are claiming that the right to define who you are is yours and yours alone (a = a). But whoever argues that the only acceptable truth lies in the statement "I ...

    Full Text Available Trata-se de uma reflexão sobre literatura e teologia, pontualmente sobre poesia e teologia. Como afirmou Edgar Morin “a literatura tem a vantagem de refletir sobre a complexidade do ser humano e sobre a quantidade incrível de seus sonhos” (MORIN, 2009:6. Já a teologia, como definida por Rubem Alves, é “um jeito de falar sobre tais coisas dando-lhes um nome e apenas distinguindo-se da poesia porque a teologia é sempre feita como prece...” (ALVES, 2005:21. O encontro das duas é a ocasião para que seja feita uma reflexão acerca de Deus, a partir do espaço da poesia, recorrendo a outra linguagem, outro conhecimento, outras bibliotecas, considerando o corpo, o desejo, a vida, o mundo na medida em que apresenta a pessoa, a sociedade e a cultura.

    Full Text Available The article deals with the French translation of the short story Amy by the Slovenian writer Mira Mihelič, made by Elza Jereb for the anthology Nouvelles slovènes (Paris, 1969. The original text, a classical narrative involving some modernist strategies, presents a syntactical feature rather unusual in Slovenian (although typical of the author Mira Mihelič: a very frequent use of participles and participial structures. Elza Jereb’s translation is accurate and precise, preserving not only the basic meaning but also the stylistic qualities, particularly the internal rhythm of the original. Some slight changes (such as for example a more consequent and logical use of italics render the text accessible to the French reader without undue simplifications. The only part of the original that seems to get lost in translation are some minor parts of the dialogue: the phonetically transcribed provincial German of the original, rich in social connotations, is translated into standard literary German, thereby losing some of its sociohistorical implications as well as some of its comical potential.

    Conclusions: This study found out the opposite effect of polymorphisms at −238 and −308 positions in TNF promoter on the outcome of BC patients. Carriers of low expressed allele −238(A have poor outcome because of low response to standard hormone therapy which presumably connected with the activation of Her2 pathway. The obtained results allow supposing that a special approach to the treatment of this group of BC patients should be used.

  15. A quackery with a difference

    Wahlberg, Ayo

    2007-01-01

    The figure of the ‘miracle cure’-peddling quack pretending spectacular properties for worthless tonics is iconic. From their 19th century traveling wagon shows to their 21st century Internet spam scams, hucksters and cranks have been consistently targeted by health authorities as a danger to public...... health. Yet, in this paper, I argue that this is only one form that the problem of ‘quackery’ has taken in the past two centuries or so in the United Kingdom. Just as Roy Porter showed how the mid-19th century professionalization of medicine gave rise to a ‘quackery with a difference’ as a whole range of...... new medical movements—homoeopathy, hydropathy, medical botany, mesmerism—actively denounced allopathic or modern medicine, I will suggest that the late 20th century birth of ‘complementary and alternative medicine’ (CAM) has resulted in yet another transformation in quackery. By examining the ways in...

    It may be concluded that the cellular and molecular mechanisms of breast cancer are complex. Therefore, carcinogenesis has a “multistep” nature and at least two or more mutations in the cells of the same clone – parent and child are required to generate malignant tumors. Thus, the development of oncogenic transformation does not necessarily mean the process of tumor formation.

    Full Text Available RCC is one of the main problems in oncourology. MiRNA expression profiles are highly specific for malignant tumors of different locations, and can be used to detect pathological molecular biomarkers and to develop the optimal treatment for each patient. 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.

    2000-03-01

    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

  20. A Pulsar and a Disk

    Kohler, Susanna

    2016-07-01

    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

    Grant Walkiria Helena

    1998-01-01

    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.

  8. A Whale of a Panorama

    2005-01-01

    [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).

  9. Bisphenol A: a scientific evaluation.

    Kamrin, Michael A

    2004-01-01

    Bisphenol A (BPA) is used in the production of high-volume polycarbonate and epoxy resin compounds found in a number of consumer products, including plastic bottles and the linings of canned goods. As a result of such applications, very small amounts of BPA can migrate into food and drink. In light of reports suggesting that low doses of BPA cause estrogenic effects in laboratory animals, concerns were raised about the safety of these consumer products, particularly plastic bottles used for feeding milk to babies. To evaluate the risk, if any, from BPA, investigations were undertaken to more precisely determine human exposure levels and more carefully study the validity of the low-dose effects reported. On the basis of the most realistic studies of BPA levels in food and drink, as well as in human urine, it has been estimated that human exposures, including those of children, are very low and range from about .001 to .1 mcg/kg body weight (bw)/day. The results of the additional toxicology studies indicated that the low-dose effects could not be consistently replicated. In light of this, a number of governments and agencies brought together independent expert panels to carefully evaluate the toxicologic studies and provide regulatory guidance. These panels came to a similar conclusion, namely, that low-dose effects have not been demonstrated. They also supported the acceptable daily intake levels previously calculated on the basis of high-dose effects shown in laboratory animals. Comparing these acceptable intakes with the best exposure estimates reveals that human doses of BPA from migration of the compound into food and drink are orders of magnitude lower than acceptable daily intakes. Thus, it is very unlikely that humans, including infants and young children, are at risk from the presence of BPA in consumer products. PMID:15520629

    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.

  14. A State-Run Enterprise: A Bane or a Boon?

    Sungjune KIM

    2015-09-01

    Full Text Available In the less than 70 years since Korean liberation, Korea has grown to be one of the world's top five ship-owning countries in 2014. This can be attributed to a few factors such as government policy, Korea Shipping Corporation (KSC, hereafter and merchant marine officers. This paper will expound the true motivations of the establishment and the privatization of KSC in 1950 and in 1968, respectively. KSC, as Korea's national shipping company, sailed along a very unusual course of development. It was established in 1950 not to foster and develop Korea's shipping industry but to help alleviate the financial burdens of the fledgling Korean government. The main cause of privatizing KSC in 1968 was a purely political decision, not an economic one as it overlapped with the rapid growth period of the shipping industry in the world, as well as in Korea. In sum, KSC, a state-run enterprise, was a bane in the short run but a boon in the long run for both the Korean government and Korea's shipping industry. If we can believe KSC followed the ordinary sailing route as a state-run enterprise, we might develop a new opinion that the national shipping company might be a financial burden in a short period, but various benefits over a long period.

    We present a detailed study of a close pair of clusters of galaxies, A3532 and A3530, and their environments. The Chandra X-ray image of A3532 reveals the presence of substructures on scales of {approx}20'' in its core. XMM-Newton maps of the clusters show excess X-ray emission from an overlapping region between them. Spectrally determined projected temperature and entropy maps do not show any signs of cluster scale mergers either in the overlapping region or in any of the clusters. In A3532, however, some signs of the presence of galaxy scale mergers are visible, e.g., anisotropic temperature variations in the projected thermodynamic maps, a wide-angle-tailed (WAT) radio source in the brighter nucleus of its dumbbell brightest cluster galaxy, and a candidate X-ray cavity coincident with the northwestern extension of the WAT source in the low-frequency radio observations. The northwestern extension in A3532 seems either a part of the WAT or an unrelated diffuse source in A3532 or in the background. There is an indication that the cool core in A3532 has been disrupted by the central activity of the galactic nucleus. A reanalysis of the redshift data reinforces the close proximity of the clusters. The excess emission in the overlapping region appears to be a result of tidal interactions as the two clusters approach each other for the first time. However, we cannot rule out the possibility of the excess being due to the chance superposition of their X-ray halos.

    2012-01-01

    This text deals with A1-homotopy theory over a base field, i.e., with the natural homotopy theory associated to the category of smooth varieties over a field in which the affine line is imposed to be contractible. It is a natural sequel to the foundational paper on A1-homotopy theory written together with V. Voevodsky. Inspired by classical results in algebraic topology, we present new techniques, new results and applications related to the properties and computations of A1-homotopy sheaves, A1-homotogy sheaves, and sheaves with generalized transfers, as well as to algebraic vector bundles over affine smooth varieties.

    1977-01-01

    Test methods require reference materials to standardize and maintain quality control. Various materials have been evaluated as possible reference materials, including a sample of bisphenol A polycarbonate without additives. Screening tests for relative toxicity under various experimental conditions were performed using male mice exposed to pyrolysis effluents over a 200-800 C temperature range. It was found that the bisphenol A polycarbonate served as a suitable reference material as it is available in large quantities, and does not significantly change with time.

  2. [A fetus is a person with a right to exist].

    Bischofberger, E

    1989-12-27

    This article is the contribution of a Jesuit priest, a teacher of medical ethics at Uppsala, to a debate inspired by a Swedish official report "The pregnant woman and fetus--2 individuals. On fetal diagnostics. On late abortions." In a society which depends upon a structured consensus as much as Sweden does, the report has been criticized for not making clearer recommendations. The author points out that the ethical dilemmas involved are so complex that they cannot be treated from a simple either/or point of view. Fetal diagnostics, for example, serve the cause of life when the aim is to avoid abortion of a healthy fetus and make it possible to cure, even at the fetal stage, or to strengthen prospective parents' readiness to accept a handicapped child. The use of fetal diagnostic for sorting out damaged and sick fetuses, however, is selective abortion and implies a violation of the principle that all human life is of equal value. The question is no longer if one will have a child or not, but which child will one have. This collision of values has inspired so many polemic statements that it is worthwhile recalling that there is always a tension between the ethically desirable and the politically possible, The report has succeeded in formulating the ethical principles in spite of the impossibility of seeing them presented as concrete recommendations. Even so, Thomas Aquinas wrote in 13th century that one cannot always apply ethical rules to laws of society. That can lead to more evil than good. PMID:2607863

  5. A search for a new gauge boson A'

    Jensen, Eric L. [William and Mary College

    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{sup +}e{sup -} 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 {alpha}'/{alpha}{sub fs} > 6 × 10{sup -8} to electrons in the mass range 65MeV < mass A' < 550MeV. The experiment will study e{sup +}e{sup -} production off an electron beam incident on a high-Z target in Hall A at Jefferson Lab. The e{sup -} and e{sup +} will be detected in the High Resolution Spectrometers (HRSs). The invariant mass spectrum of the e{sup +}e{sup -} 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{sup +}e{sup -} reaction, and set an upper limit of {alpha}'/{alpha}{sub fs} ~ 10{sup -6}.

  6. RelA: a tale of a stitch in time.

    Korc, Murray

    2016-08-01

    Pancreatic ductal adenocarcinoma (PDAC) is a deadly cancer in which NF-κB pathways promote biological aggressiveness. In this issue of the JCI, Lesina et al. investigated the role of RelA, the p65 partner of p50 that together form the most common NF-κB complex, in the early stages of pancreatic malignant transformation and in established PDAC. By deleting Rela in the context of an oncogenic Kras-driven autochthonous model of PDAC, the authors demonstrated that RelA is a mediator of oncogene-induced senescence (OIS) and the senescence-associated secretory phenotype (SASP) that attenuates acinar-to-ductal metaplasia, pancreatic intraepithelial neoplasia (PanIN) formation, and PanIN progression to PDAC. Loss of the tumor-suppressor function of RelA in the early stages of Kras-driven pancreatic neoplastic transformation was associated with decreased OIS and SASP and a protumorigenic tumor microenvironment that harbored more M2 macrophages and myeloid-derived suppressor cells. The beneficial effects of RelA were mediated by increased expression of CXCL1 and its activation of CXCR2. By contrast, in advanced stages of Kras-driven murine PDAC, loss of p53 or p16 was associated with senescence bypass, and RelA deficiency in this context attenuated cancer cell proliferation and prolonged mouse survival, indicating that RelA enhances tumor progression in established PDAC.

  8. 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. PMID:1286457

  9. A toy model for a diatomic molecule

    Hecker Denschlag, Johannes

    2016-08-01

    We introduce a toy model for a diatomic molecule which is based on coupling electronic and nuclear spins to a rigid rotor. Despite its simplicity, the model can be used scientifically to analyze and understand complex molecular hyperfine spectra. In addition, the model has educational value as a number of fundamental symmetries and conservation laws of the molecule can be studied. Because of its simple structure, the model can be readily implemented as a computer program with comparatively short computing times on the order of a few seconds.

  10. When a Family Requests a White Doctor.

    Reynolds, Kimberly L; Cowden, John D; Brosco, Jeffrey P; Lantos, John D

    2015-08-01

    Parents sometimes request that a doctor of a particular race or ethnic group not care for their child. Such requests sometimes seem legitimate and other times seem offensive. The difference reflects a clash of fundamental values. Generally, we try to respect patient or parental preferences. Requests based on racist attitudes, however, do not seem worthy of respect. But where should we draw the line? In this ethics rounds, we present a situation in which parents requested a white doctor and analyze the ways in which doctors might think about and respond to such a request. PMID:26169433

    In [7] Ghirardato, Macheroni and Marinacci (GMM) propose a method for distinguishing between perceived ambiguity and the decision-maker's reaction to it. They study a general class of preferences which they refer to as invariant biseparable. This class includes CEU and MEU. They axiomatize a subclass of a-MEU preferences. If attention is restricted to finite state spaces, we show that any a-MEU preference relation, satisfies GMM's axioms if and only if a = 0 or 1, that is, the preferences mus...

  12. Building a Database for a Quantitative Model

    Kahn, C. Joseph; Kleinhammer, Roger

    2014-01-01

    A database can greatly benefit a quantitative analysis. The defining characteristic of a quantitative risk, or reliability, model is the use of failure estimate data. Models can easily contain a thousand Basic Events, relying on hundreds of individual data sources. Obviously, entering so much data by hand will eventually lead to errors. Not so obviously entering data this way does not aid linking the Basic Events to the data sources. The best way to organize large amounts of data on a computer is with a database. But a model does not require a large, enterprise-level database with dedicated developers and administrators. A database built in Excel can be quite sufficient. A simple spreadsheet database can link every Basic Event to the individual data source selected for them. This database can also contain the manipulations appropriate for how the data is used in the model. These manipulations include stressing factors based on use and maintenance cycles, dormancy, unique failure modes, the modeling of multiple items as a single "Super component" Basic Event, and Bayesian Updating based on flight and testing experience. A simple, unique metadata field in both the model and database provides a link from any Basic Event in the model to its data source and all relevant calculations. The credibility for the entire model often rests on the credibility and traceability of the data.

  13. A Project Team: a Team or Just a Group?

    2014-06-01

    Full Text Available This paper deals with issues related to work in either teams or groups. The theoretical part discusses a team and a group with regards to its definition, classification and basic distinction, brings in more on the typology of team roles, personality assessment and sociometric methods. The analytical part tests the project (work team of a medical center represented in terms of personality and motivational types, team roles and interpersonal team relations concerning the willingness of cooperation and communication. The main objective of this work is to verify the validity of the assumptions that the analyzed team represents a very disparate group as for its composition from the perspective of personality types, types of motivation, team roles and interpersonal relations in terms of the willingness of cooperation and communication. A separate output shall focus on sociometric investigation of those team members where willingness to work together and communicate is based on the authors’ assumption of tight interdependence.

  14. A simple model of a swing

    Mayer, V. V.; Varaksina, E. I.

    2016-07-01

    The paper presents a simple model of a swing meant for undergraduates’ educational experiments. The purpose of these experiments is the experimental study of physical principles of self-oscillations, free, forced and parametric oscillations. The model contains a pendulum. A coil with a movable steel core serves as its load. A neodymium magnet is placed at the lower end of the core. A magnetically operated sealed switch is stationed under the magnet at the equilibrium position of the pendulum. The switch is connected in series with the coil and a battery. If we displace the pendulum from the equilibrium position, the pendulum makes undamped oscillations. The system receives energy every time the core is drawn into the coil at the lower position of the pendulum.

  15. A porous metal cathode (a thermoemission converter)

    Kozlov, V.I.; Avdeyev, V.Ye.

    1983-01-01

    The porous metallic cathode, which contains a body and the basic sponge attached to it with an active substance, made in the form of a base with an emitting projection, is distinguished by the fact that in order to increase the service life of the cathode, the based sponges on the side opposite the projection have a groove in which the replenishing chamber made of a difficulty fusible metal and filled with a mixture of tungsten and an active substance with a porosity of 35 to 80 percent which is open towards the projection is positioned, where the transverse cross section of the replenishing chamber intersects the transverse cross section of the projection, while the porosity of the basic sponge is 24 to 26 percent. The cathode is distinguished by the fact that a screen made of a difficultly fusible metal is installed on the facial surface with an opening for the projection and is connected with the body and with this surface.

    Berg, Jeremy E.; Faraj, Ahmad A.

    2011-08-02

    Methods, systems, and products are disclosed for broadcasting a message in a parallel computer. The parallel computer includes a plurality of compute nodes connected together using a data communications network. The data communications network optimized for point to point data communications and is characterized by at least two dimensions. The compute nodes are organized into at least one operational group of compute nodes for collective parallel operations of the parallel computer. One compute node of the operational group assigned to be a logical root. Broadcasting a message in a parallel computer includes: establishing a Hamiltonian path along all of the compute nodes in at least one plane of the data communications network and in the operational group; and broadcasting, by the logical root to the remaining compute nodes, the logical root's message along the established Hamiltonian path.

  18. [A simulation exercise in a flu clinic].

    Barthe, Juliette; Aubert, Jean-Pierre; Lecapitaine, Anne-Lise; Lecompte, Françoise; Szwebel-Chikli, Céline

    2011-01-01

    A simulation exercise aimed at assessing the management and provision of ambulatory care in the context of a highly pathogenic influenza pandemic was conducted in a specifically dedicated consultation center (Centre de Consultation Dédié (CCD) à la grippe) based on official French guidelines. The exercise was carried out in a school in Paris equipped to simulate a "flu clinic". 3 practitioners provided treatment lasting 2 hours to nursing students acting as patients. The exercise highlighted a number of major organizational issues. Staff were found to be unable to manage the center and to perform patient transfers; face masks were not routinely and consistently worn by doctors and patients; and communication between professionals within the clinic was limited. The exercise showed that much remains to be done to ensure that "flu clinics" are effective and functional. The results suggest that the exercise will need to be repeated on a larger scale and over a longer period. PMID:22365047

  19. Morphing a Plasmonic Nanodisk into a Nanotriangle

    Schmidt, Franz P.; Ditlbacher, Harald; Hofer, Ferdinand; Krenn, Joachim R; Hohenester, Ulrich

    2014-01-01

    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 morphi...

    2014-07-01

    Full Text Available Ankylosing spondylitis is a chronic inflammatory disease that affects the synovial membrane, joint entheses and para-articular structures of the spine, including the sacroiliac joints and limbs. We present a case of ankylosing spondylitis that had evolved for 12 years despite the relatively early diagnosis and treatment, showing flexion deformity and limitation of spinal movements. On radiological examination an early evolution to ankylosis was observed, which motivated us to make a reflection and a question.

  4. Teratogenia da vitamina A Vitamin A teratogenicity

    Maria Helena de Castro Chagas

    2003-09-01

    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.

  6. A Psychological Factor Affecting a Cardiac Condition in a Psychotherapist

    R Waxman

    2009-03-01

    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.

  7. A PURCHASING DECISION: SELECTING A SUPPLIER FOR A CONSTRUCTION COMPANY

    Ozden BAYAZIT; Birsen KARPAK; Ayhan YAGCI

    2006-01-01

    Supplier selection is one of the most crucial activities performed by organizations because of its strategic importance. Supplier selection is a multi-objective problem involving both quantitative and qualitative criteria. Over the years a number of quantitative approaches have been tried. Although the Analytic Hierarchy Process (AHP) has previously been used in supplier selection problems, one major weakness of the application-oriented AHP literature is that it tends to focus on the mechanics of AHP instead of on the theoretical and practical implications associated with finding a solution. Though it is one of the most extensively used Multiple Criteria Decision Analysis methodologies, our literature search indicated that most studies found the best solution and stopped there, ignoring sensitivity analysis. Performing sensitivity analysis is very important for practical decision making, sometimes even as important as finding the best solution. In this paper for the first time a comprehensive application of AHP for a real-world case is presented along with sensitivity analysis in choosing the best suppliers for a Turkish construction company. As a result of this study the company decided to allocate the order quantities between the two top suppliers.

  8. Pellets - A fuel with a future

    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

    Full Text Available Twenty years passed after the dissolution of the USSR and the re-birth of Russian Federation and Central Asian states in the world arena in such a unipolar world. Since the rise of Vladimir Putin to power Russia resists on unipolar system and sees that as a treat to its security. Hence, Kremlin perceives that the economic strength is the sine qua non for the future of Russia in order to sustain a Big Power status not only in its region but also in the world. In 2011, Russia, Belarus and Kazakhstan have achieved to form a Customs Union among them and invited all the states in the region to join the organization. There were thesis which mainly argued that Russia would no longer be a “power” in the Central Asia and could only be a regional power just in case of maintaining of its own unity. However, the circumstances have changed in the region accordingly Russian weight as a result of the new conjuncture. In 2012, Russia had a new presidential election and Putin returned to Kremlin as President himself. It has been understood from his words that Kremlin's new strategy to be focused on creating a Eurasian Union including Kyrgyzstan and Tajikistan at the first stage. It is aimed to analyze in this study that whether this project could be successful and if so, what could be the impacts on world order in terms of competition between Russia, the United States and China also. And finally, what could be the result of such an organization for the Russia.

    Group A streptococcal (GAS) infections are associated with a number of human diseases, including pharyngitis, impetigo, necrotizing fasciitis, streptococcal toxic shock syndrome and rheumatic heart disease. An increase in the incidence of severe GAS infections in Western countries, and the awareness of the burden of GAS-associated diseases in developing nations, which remains high in spite of the availability of antibiotics, has provided the impetus for development of a safe and efficacious GAS vaccine. This has focused on the M protein, a major GAS virulence factor, however, with the publication of several GAS genomes, a number of non-M vaccine candidates are now under investigation. PMID:15732524

  20. A Spectrum is Worth a Thousand Pictures

    Gelderman, Richard F.

    2006-12-01

    A wise astronomer once pointed out that if a picture is worth a thousand words, then a spectrum is worth a thousand pictures. Unfortunately, spectra are rarely emphasized in the introductory astronomy courses and few students exit such a course with any meaningful understanding or appreciation of spectroscopy. Part of the problem is lack of background knowledge; the typical introductory astronomy student has little experience with spectroscopy or atomic physics. Another issue is that spectra are not pretty pictures and are not intuitively understandable. We present and discuss a series of “minds-on” exercises and activities built into a college-level “stars, galaxies, and cosmology” intro astronomy course. The lessons are structured to help students improve their ability to recognize patterns and improve their ability to really see the details in front of them. Another goal is for students to realize there is “more than meets the eye” to learn how to discover “hidden” diagnostics, such as different sources of light their eyes see as white light. A curriculum that emphasizes spectroscopy also provides the opportunity to stress the story of the “Harvard Women,” a tale that bridges gender gaps and often humanizes scientists in the eyes of non-science majors. Finally, with a solid foundation in spectroscopy, students are better prepared to understand exciting topics such as Hubble’s Law and the importance of primordial nucleosynthesis.

    Solveig Magnus Reindal

    2010-01-01

    Full Text Available Recently, scholars have argued that disability activists' redefinition of disability' as a social problem, rather than a medical problem, is maleficent, unjust, and inconsistent. It seems that the discussion on whether disability is a medical or a social category is not settled and that disability is an essentially contested concept. However, the question is: What is the social aspect in disability? It appears that there is some confusion as to what the social is in a social definition of disability. The article pursues possible reasons for this confusion by investigating the critique of the social model. This is followed by a discussion on what a possible space for the social might be in a social definition of disability. Such a space is illuminated by using the framework of the World Health Organization's International Classification of Functioning Disability and Health (ICF. The article suggests that disability as a social category is not inconsistent if reframed within a social relational model of disability.http://dx.doi.org/10.5324/eip.v4i1.1744

  2. A vision system for a Mars rover

    Wilcox, Brian H.; Gennery, Donald B.; Mishkin, Andrew H.; Cooper, Brian K.; Lawton, Teri B.; Lay, N. Keith; Katzmann, Steven P.

    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.

  3. SUPERNOVA 1987A: CELEBRATING A SILVER JUBILEE

    2013-12-01

    Full Text Available The story of the SN 1987A explosion is briefly reviewed. Although this supernova was somewhat peculiar, the study of SN 1987A has clarified quite a number of important aspects of the nature and the properties of supernovae, such as the confirmation of the core collapse of a massive star as the cause of the explosion, as well the confirmation that the decays 56Ni–56Co–56Fe at early times and 44Ti–44Sc at late times, are the main sources of the energy radiated by the ejecta. Still we have not been able to ascertain whether the progenitor was a single star or a binary system, nor have we been able to detect the stellar remnant, a neutron star that should be produced in the core collapse process.

    Full Text Available The objective of this study is to explore and describe a marketing strategy for a nursing college. An explorative and descriptive research design, within the context of a nursing college and affiliated hospitals, was followed. A literature study of marketing models was undertaken and the Delphi-method was utilised to determine the contribution of marketing staff and the possible content of a marketing strategy for a nursing college. The results were utilised to describe guidelines for such a strategy, consisting of marketers/marketing agents, target market, product, price, promotional activities, place and market research. Recommendations include the planning, implementation and evaluation of strategy, inservice training for potential marketing agents, inclusion of marketing as part of the formal education of tutors and nurse managers,as well as an impact study of the scholar as the main consumer.

  5. A Random Laser as a Dynamical Network

    Höfner, M; Henneberger, F

    2013-01-01

    The mode dynamics of a random laser is investigated in experiment and theory. The laser consists of a ZnCdO/ZnO multiple quantum well with air-holes that provide the necessary feedback. Time-resolved measurements reveal multimode spectra with individually developing features but no variation from shot to shot. These findings are qualitatively reproduced with a model that exploits the specifics of a dilute system of weak scatterers and can be interpreted in terms of a lasing network. Introducing the phase-sensitive node coherence reveals new aspects of the self-organization of the laser field. Lasing is carried by connected links between a subset of scatterers, the fields on which are oscillating coherently in phase. In addition, perturbing feedback with possibly unfitting phases from frustrated other scatterers is suppressed by destructive superposition. We believe that our findings are representative at least for weakly scattering random lasers. A generalization to random laser with dense and strong scattere...

  6. A numerical model for a room fire

    A simple room fire experiment has been used as a development case for numerical fire simulation based on computational fluid dynamics. Experimental values (Steckler et al. 1982) are used to verify simulation. A limited method to use a flee flow boundary condition has been described (flow is assumed to be oblique to the boundary). Description of buoyancy terms, atmospheric pressure and additional terms of turbulence due to buoyancy are also given. Fire source is described as a predefined heat source. Comparison to the experiments shows that flow velocity at the room door, which is the only opening to the room, can be predicted with a good and temperature with a moderate accuracy.

    2014-01-10

    We present a 250 ks Chandra observation of the cluster merger A2034 with the aim of understanding the nature of a sharp edge previously characterized as a cold front. The new data reveal that the edge is coherent over a larger opening angle and is significantly more bow-shock-shaped than previously thought. Within ∼27° about the axis of symmetry of the edge, the density, temperature, and pressure drop abruptly by factors of 1.83{sub −0.08}{sup +0.09}, 1.85{sub −0.41}{sup +0.41}, and 3.4{sub −0.7}{sup +0.8}, respectively. This is inconsistent with the pressure equilibrium expected of a cold front and we conclude that the edge is a shock front. We measure a Mach number M=1.59{sub −0.07}{sup +0.06} and corresponding shock velocity v {sub shock} ≅ 2057 km s{sup –1}. Using spectra collected at the MMT with the Hectospec multi-object spectrograph, we identify 328 spectroscopically confirmed cluster members. Significantly, we find a local peak in the projected galaxy density associated with a bright cluster galaxy that is located just ahead of the nose of the shock. The data are consistent with a merger viewed within ∼23° of the plane of the sky. The merging subclusters are now moving apart along a north-south axis approximately 0.3 Gyr after a small impact parameter core passage. The gas core of the secondary subcluster, which was driving the shock, appears to have been disrupted by the merger. Without a driving 'piston,' we speculate that the shock is dying. Finally, we propose that the diffuse radio emission near the shock is due to the revival of pre-existing radio plasma that has been overrun by the shock.

  8. Turning a Wild Plant into a Model A Dvu Story

    Daniel Ioan PACURAR

    2009-06-01

    Full Text Available In the past two decades we have witnessed how a useless wild weed has been transformed from an anonymous into a model plant, probably the most widely cultivated plant species. The process has been rather slowly in the beginning, very laborious on the way, extremely expensive and time consuming, but the outcome is priceless the knowledge that is most likely to frame and fill the blueprint of the first artificial plant, as system biology promises. The plant species is Arabidopsis thaliana and the growers are highly qualified researchers worldwide. This review introduces a new anonymous Brachypodium distachyon that raised big hopes for addressing specific problems of fundamental and practical biology in temperate cereals and forage grasses, and is rapidly becoming a sweetheart for the researchers working with these crops, and not only.

    Full Text Available This paper deals with issues related to work in either teams or groups. The theoretical part which discusses a team and a group with regards to its definition, classification and basic distinction brings in more on the typology of team roles, personality assessment and sociometric methods. The analytical part tests the project (work team of a medical center represented in terms of personality and motivational types, team roles and interpersonal team relations concerning the willingness of cooperation and communication. The main objective of this work was to determine whether the existing team is not by its nature rather a working group that contributes to the generally perceived stagnation of that field.

    Full Text Available We report here a case of cystic lymphangioma of scrotum presenting as acute scrotum due to haemorrhage. The diagnosis was confirmed on ultrasonography and magnetic resonance imaging and managed successfully by surgical excision. There was past history of bilateral congenital cataract for which the patient had undergone surgery with complete visual recovery. Scrotal cystic lymphangioma complicated by haemorrhage is rare; hence, the case is being reported with a review of literature.

  13. Tricolorin A as a Natural Herbicide

    Blas Lotina-Hennsen

    2013-01-01

    Full Text Available Tricolorin A acts as pre- and post-emergence plant growth inhibitor. In pre-emergence it displays broad-spectrum weed control, inhibiting germination of both monocotyledonous (Lolium mutliflorum and Triticum vulgare and dicotyledonous (Physalis ixocarpa and Trifolium alexandrinum seeds, being the dicotyledonous seeds the most inhibited. Tricolorin A also inhibited seedling growth, and seed respiration, and since the concentrations required for inhibiting both germination and respiration were similar, we suggest that respiration is one of its targets. Tricolorin A at 60 µM acts as a post- emergence plant growth inhibitor by reducing dry plant biomass by 62%, 37%, 33%, and 22% for L. multiflorum, T. alexandrinum, T. vulgare, and P. ixocarpa, respectively, 18 days after its application. In order to determine the potency of tricolorin A as a plant growth inhibitor, paraquat was used as control; the results indicate that tricolorin A acts as a non-selective post-emergence plant growth inhibitor similar to paraquat, since both reduced the biomass production in P. ixocarpa and T. alexandrinum. Therefore, we suggest that tricolorin A will be a good biodegradable herbicide for weeds.

  15. Scattering of a Baseball by a Bat

    Cross, R; Cross, Rod; Nathan, Alan M.

    2006-01-01

    A ball can be hit faster if it is projected without spin but it can be hit farther if it is projected with backspin. Measurements are presented in this paper of the tradeoff between speed and spin for a baseball impacting a baseball bat. The results are inconsistent with a collision model in which the ball rolls off the bat and instead imply tangential compliance in the ball, the bat, or both. If the results are extrapolated to the higher speeds that are typical of the game of baseball, they suggest that a curveball can be hit with greater backspin than a fastball, but by an amount that is less than would be the case in the absence of tangential compliance.

  16. Hoarding: From a Symptom to a Disorder

    Suheyla Dogan Bulut

    2015-09-01

    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.

  17. A Small Deformation of a Simple Theory

    Buican, Matthew

    2016-01-01

    We study an interesting relevant deformation of the simplest interacting N=2 SCFT---the original Argyres-Douglas (AD) theory. We argue that, although this deformation is not strictly speaking Banks-Zaks like (certain operator dimensions change macroscopically), there are senses in which it constitutes a mild deformation of the parent AD theory: the exact change in the "a" anomaly is small and is essentially saturated at one loop. Moreover, contributions from IR operators that have a simple description in the UV theory reproduce a particular limit of the IR index to a remarkably high order. These results lead us to conclude that the IR theory is an N=1 SCFT with the smallest-known "a" and "c" central charges for an interacting SCFT in four dimensions.

    Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic luminosity ($L\\sim 3 \\times 10^{53}$ erg s$^{-1}$) and its relative proximity ($z=0.34$), GRB 130427A was a unique event that reached the highest fluence observed in the gamma-ray band. Here we present a comprehensive multiwavelength view of GRB 130427A with Swift, the 2-m Liverpool and Faulkes telescopes and by other ground-based facilities, highlighting the evolution of the burst emission from the prompt to the afterglow phase. The properties of GRB 130427A are similar to those of the most luminous, high-redshift GRBs, suggesting that a common central engine is responsible for producing GRBs in both the contemporary and the early Universe and over the full range of GRB isotropic energies.

  20. Electrophoresis of a polyelectrolyte through a nanopore

    Ghosal, S

    2006-01-01

    A hydrodynamic model for determining the electrophoretic speed of a polyelectrolyte through a nanopore is presented. It is assumed that the speed is determined by a balance of electrical and viscous forces arising from within the pore and that classical continuum electrostatics and hydrodynamics may be considered applicable. An explicit formula for the translocation speed as a function of the pore geometry and other physical parameters is obtained and is shown to be consistent with experimental measurements on DNA translocation through nanopores in silicon membranes. Experiments also show a weak dependence of the translocation speed on polymer length that is not accounted for by the present model. It is hypothesized that this is due to secondary effects that are neglected here.

  1. When is a bottleneck a bottleneck?

    Schadschneider, Andreas; Popkov, Vladislav

    2015-01-01

    Bottlenecks, i.e. local reductions of capacity, are one of the most relevant scenarios of traffic systems. The asymmetric simple exclusion process (ASEP) with a defect is a minimal model for such a bottleneck scenario. One crucial question is "What is the critical strength of the defect that is required to create global effects, i.e. traffic jams localized at the defect position". Intuitively one would expect that already an arbitrarily small bottleneck strength leads to global effects in the system, e.g. a reduction of the maximal current. Therefore it came as a surprise when, based on computer simulations, it was claimed that the reaction of the system depends in non-continuous way on the defect strength and weak defects do not have a global influence on the system. Here we reconcile intuition and simulations by showing that indeed the critical defect strength is zero. We discuss the implications for the analysis of empirical and numerical data.

    The authors report about a small bore pistol with silencer. In addition, the silencer can be sealed up by a rubber plate. This leads to a false estimation of the shooting distance. Also at close range shots the shot with the silencer and the rubber seal leaves hardly gunshot residues. The bullet wipe persists but microradiography shows his changed morphological composition. The use of the rubber seal leads predominantly to atypical bullet holes. PMID:10829239

    Shame may be considered one of the most painful emotions that an individual must endure. Recent research within the scientific discipline of theology has identified the fact that there has been little theological study on shame from a basis-theoretical perspective. This has resulted in a deficiency of theological-practical interventions to assist pastoral counsellors and believers in addressing shame from a Biblical-integrative perspective. Although many of the scientific disci...

    Abstract: We study human capital depletion and formation in an economy open to out-migration, as opposed to an economy which is closed. Under the natural assumption of asymmetric information, the enlarged opportunities and the associated different structure of incentives can give rise to a brain gain in conjunction with a brain drain. Migration by high-skill members of its workforce notwithstanding, the home country can end up with a higher average level of human capital per worker.;

  12. A second supernova inside Puppis A?

    Here we present narrow-band images of an unusual swirl structure located near the centre of the Puppis A supernova remnant, which reveal three overlapping filamentary systems of highly diverse composition. One is dominated by emission lines of nitrogen, one by oxygen and one by sulphur. Spectra indicate that these small rings have high velocities and a corresponding kinematic age of less than 800 yr. The youth and unusual chemistry lead us to suggest that a second supernova has exploded within the shell of Puppis A, giving rise to the swirl structure. (author)

    Musical acoustics is an interesting sub-field of physics which is usually able to engage students in a dual perspective, by combining science and art together. The physics principles involved in most musical instruments can be easily demonstrated with standard laboratory equipment and can become part of lecture or lab activities. In particular, we will show in this paper how to simulate a guitar using a conventional sonometer, in relation to the problem of the instrument intonation, i.e., how to obtain correctly tuned notes on a guitar or similar string instruments.

    2012-11-01

    Micropipettes are widely used in many scientific and engineering fields. However, it is hardly known that a droplet dispensed from a plastic pipette tip has a considerable amount of charges (order of 10-10 C). Here we report that the charged droplet is dispensed from a commercial and disposable plastic pipette tip and this charge is originated from the natural electrification between a solution and the inner surface of the pipette tip. The charge amount is dependent on not only the physicochemical properties of a solution (e.g., pH and a concentration) but also dispensing environments (e.g., atmospheric humidity and type of commercial pipette tip). To investigate the effects of the charge on the droplet dispensing, we calculate the electrical force between the droplet and the pipette tip though numerical simulation. The micropipette users especially, who are dealing with discrete droplets in their experiments, should consider this charge effect in their dispensing of a droplet.

  16. A City Is a Complex Network

    Jiang, Bin

    2015-01-01

    A city is not a tree but a semi-lattice. To use a more fashionable term, a city is a complex network. The complex network constitutes a unique topological perspective on cities and enables us to better understand the kind of problem a city is. The topological perspective differentiates it from the perspectives of Euclidean geometry and Gaussian statistics that deal with essentially regular shapes and more or less similar things. Many urban theories, such as the Central Place Theory, Zipf's Law, the Image of the City, and the Theory of Centers can be interpreted from the point of view of complex networks. A livable city consists of far more small things than large ones, and their shapes tend to be irregular and rough. This chapter illustrates the complex network view and argues that we must abandon the kind of thinking guided by Euclidean geometry and Gaussian statistics, and instead adopt fractal geometry, power-law statistics, and Alexander's living geometry to develop sustainable cities.

  17. Converting a Display Screen into a Touchscreen

    Qun Wang; Jun Cheng; San-Ming Shen; Yi-Jiang Shen; Jian-Xin Pang

    2014-01-01

    A method is presented to convert any display screen into a touchscreen by using a pair of cameras. Most state of art touchscreens make use of special touch-sensitive hardware or depend on infrared sensors in various configurations. We describe a novel computer-vision-based method that can robustly identify fingertips and detect touch with a precision of a few millimeters above the screen. In our system, the two cameras capture the display screen image simultaneously. Users can interact with a computer by the fingertip on the display screen. We have two important contributions:first, we develop a simple and robust hand detection method based on predicted images. Second, we determine whether a physical touch takes places by the homography of the two cameras. In this system, the appearance of the display screen in camera images is inherently predictable from the computer output images. Therefore, we can compute the predicted images and extract human hand precisely by simply subtracting the predicted images from captured images.

    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 report a case of Staphylococcus aureus infective endocarditis in a patient presenting with fever and rare cutaneous manifestations of Osler Nodes and Janeway Lesions. There had not been any distinct risk factors. His echocardiography subsequently revealed vegetation at the anterior mitral valve leaflet. As Staphylococcus aureus infective endocarditis is of utmost significance in morbidity and mortality, a sharp clinical acumen and follow up investigations is required alongside a prolonged course of antibiotics. Our patient was then started on intravenous cloxacillin for 28 days and gentamicin for 5 days to which he made good progress and recovery. PMID:24814630

    2011-01-01

    Musical acoustics is an interesting sub-field of physics which is usually able to engage students in a dual perspective, by combining science and art together. The physics principles involved in most musical instruments can be easily demonstrated with standard laboratory equipment and can become part of lecture or lab activities. In particular, we will show in this paper how to simulate a guitar using a conventional sonometer, in relation to the problem of the instrument intonation, i.e., how to obtain correctly tuned notes on a guitar or similar string instruments.

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

    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. PMID:23419849

  11. A Monopole Near a Black Hole

    Bunster, C; Bunster, Claudio; Henneaux, Marc

    2007-01-01

    We study an electric charge held at rest outside a magnetically charged black hole. We find that even if the electric charge is treated as a perturbation on a spherically symmetric magnetic Reissner-Nordstrom hole, the geometry at large distances is that of a magnetic Kerr-Newman black hole. When the charge approaches the horizon and crosses it, the exterior geometry becomes that of a Kerr-Newman hole with electric and magnetic charges and with total angular momentum given by the standard value for a charged monopole pair. Thus, in accordance with the "no-hair theorem", once the charge is captured by the black hole, the angular momentum associated with the charge monopole system, looses all traces of its exotic origin and it is perceived from the outside as common rotation. It is argued that a similar analysis performed on Taub-NUT space should give the same result, namely, if one holds an ordinary mass outside of the horizon of a Taub-NUT space with only magnetic mass, the system, as seen from large distance...

  19. Just a routine operation: a critical discussion.

    McClelland, G; Smith, M B

    2016-05-01

    This article has summarised a critical discussion of the human factors that contributed to the death of a patient from a failure to respond appropriately to a 'can't intubate, can't ventilate' scenario. The contributory factors included the clinical team's inability to communicate, prioritise tasks and demonstrate effective leadership and assertive followership. The film Just a routine operation has now been in circulation for several years. When a system is designed and introduced with the intention of making a change to clinical practice, it can quickly become just another component of an organisation's architecture and complacency around its use can develop. This article has been written specifically for perioperative practitioners to renew the debate around the human factors that contribute to patient harm. By critically discussing Just a routine operation and attempting to review why the incident occurred, this article has attempted to emphasise that some of the conditions and behaviours that contributed to the death of Elaine Bromiley may be latent within our organisations and teams, and may continue to contribute to failures that affect patient safety.

    Full Text Available A vortex model of a helicopter rotor is presented. Each blade of the rotor has three degrees of freedom: flapping, lagging and feathering. The motions after each degree of freedom are also known for all blades. The blade is modelled as a thin vortex surface. The wakes are free fluid surfaces. A system of five equations are obtained: the first one is the integral equation of the lifting surface (rotor, the next three describe the wakes motion, and the last one relates the vortex strength on the wakes and the variation of vorticity on the rotor. A numerical solution of this system is presented. To avoid the singularities that can occur due to the complexity of vortex system, a desingularized model of the vortex core was adopted. A Mathcad worksheet containing the method has been written.The original contribution of the work. The calculation method of the motion of the wakes free vortex system, the development of the vortex cores in time and a new method to approximate the aerodynamic influence of remoted wake regions.

  16. A phylogenetic blueprint for a modern whale.

    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.

    2016-01-01

    We present the second multi-frequency radio detection of a reverse shock in a $\\gamma$-ray burst. By combining our extensive radio observations of the Fermi-LAT GRB 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 $\\lesssim10~$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 $n_0\\approx10^{-3}~$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, $N_{\\rm H} \\approx 1.5\\times10^{22}~$cm$^{-2}$, and a high rest-frame optical extinction, $A_{\\rm V}\\approx3.4~$mag. We...

  5. Morphing a plasmonic nanodisk into a nanotriangle.

    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.

    2014-01-01

    Long-duration gamma-ray bursts (GRBs) are an extremely rare outcome of the collapse of massive stars and are typically found in the distant universe. Because of its intrinsic luminosity (L approx. 3 x 10(exp 53) ergs/s and its relative proximity (z = 0.34), GRB 130427A reached the highest fluence observed in the gamma-ray band. Here, we present a comprehensive multiwavelength view of GRB 130427A with Swift, the 2-meter Liverpool and Faulkes telescopes, and by other ground-based facilities, highlighting the evolution of the burst emission from the prompt to the afterglow phase. The properties of GRB 130427A are similar to those of the most luminous, high-redshift GRBs, suggesting that a common central engine is responsible for producing GRBs in both the contemporary and the early universe and over the full range of GRB isotropic energies.

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. A fat Higgs with a magnetic personality

    Craig, Nathaniel; Stolarski, Daniel; Thaler, Jesse

    2011-11-01

    We introduce a novel composite Higgs theory based on confining supersymmetric QCD. Supersymmetric duality plays a key role in this construction, with a "fat" Higgs boson emerging as a dual magnetic degree of freedom charged under the dual magnetic gauge group. Due to spontaneous color-flavor locking in the infrared, the electroweak gauge symmetry is aligned with the dual magnetic gauge group, allowing large Yukawa couplings between elementary matter fields and the composite Higgs. At the same time, this theory exhibits metastable supersymmetry breaking, leading to low-scale gauge mediation via composite messengers. The Higgs boson is heavier than in minimal supersymmetric theories, due to a large F -term quartic coupling as well as small non-decoupling D-terms. This theory predicts quasi-stable TeV-scale pseudo-modulini, some of which are charged under standard model color, possibly giving rise to long-lived R-hadrons at the LHC.

  10. A new approach to a unified force

    The assumption is presented that the true structure of the world is a six dimensional (6D) Euclidian space in which our 4D world is embedded properly. Because of the local isomorphism of SO(6) and SU(4) physics developed for this space crystallizes as being very symmetric with only one force and no gravity. Analyzing how this 6D physics can be interpreted by a 4D observer it emerges that the transition seems to be something like a universal remedy. It shows that the result allows formulating our known physics. It gives reason why quantum physics is a probabilistic theory, can explain quarks as transformed 6D symmetry, can deduct our three forces from the one 6D force, can introduce particle mass in the Lagrange density and can implement gravity. The paper presents a structural description. To achieve quantitative results mathematical problems have to be overcome.

    Takotsubo syndrome (TTS) is still a relatively understudied and often undetected disease. It is usually preceded by emotional or physical triggers. We here report a case of TTS following a car accident. Typical apical ballooning with moderate reduction of left ventricular ejection fraction (LVEF) and increased level of pro-B-type natriuretic peptide (BNP) as well as slightly increased creatine kinase and troponin T values were found in this 76-year-old female patient, 6 h after a car accident. At 10 weeks follow-up, we observed a normalization of regional wall motion, LVEF, electrocardiogram and pro-BNP. TTS is an acute heart failure syndrome and an important differential diagnosis of acute coronary syndrome. PMID:27377800

  12. A view to a (staged) kill?

    2015-01-01

    Is it acceptable, in principle, to shoot wild animals as a sport? The ethical controversy around recreational hunting is not only of academic interest but plays an important role in public and political discussions concerning the legitimacy of hunting. For the hunter, hunting is typically imbued...... with a perception of deeper meaning. For ardent non-hunters it may be hard to understand the meaning of enjoying nature by shooting at other living beings. This lack of mutual understanding makes it difficult to create a dialogue. However, the issue is not just about whether or not to accept hunting...... but also the specific forms of hunting. The aim of the paper is to explore the attitudes at stake in debates about a controversial form of hunting: shooting of birds that are farm reared and subsequently released for the purpose of being hunted. The paper is based on a nationally representative survey...

  13. A cabeça voraz

    Betty Mindlin

    1996-08-01

    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. Também para os índios, escrever, contar, divulgar e usar nas próprias escolas os seus mitos é importante para reafirmar a identidade étnica e valorizar sua participação na sociedade brasileira.The article focuses an indian myth about a flying and voracious head, that was told to the author by several indian tribes from the Amazon, such as the Tupari, the Macurap, the Jabuti, the Aruá, the Sateré-Mawé.

  17. A Year To Make a Difference

    Howell, J. Emory

    1999-01-01

    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. Educ. 1998, 75, 64-66), one class member asked why we only discussed and read about what teachers

  18. Orbit of a Giant and a Dwarf

    Kohler, Susanna

    2015-11-01

    The binary system Procyon, located a mere 11 light-years away, consists of a bright, subgiant star and a faint white dwarf presenting a distinct challenge for astronomers to observe. But careful analysis of two decades of precise measurements with the Hubble Space Telescope has now finally revealed some of its secrets.Challenging ObservationsPerturbations were detected as early as 1844 in the orbit of Procyon, originally thought to be a single star. Astronomers of the time suspected that this wobbling was due to the pull of a companion orbiting Procyon, but it wasnt until five decades later that the companion was first detected visually.Why? Because the subgiant Procyon A is the 8th brightest star in the sky. Its companion, on the other hand, is a white dwarf thats fainter (in visual wavelengths) by a factor of nearly 16,000! And the two stars are separated by an angular distance of less than 5.Due to the difficulty observing the system, the measurements of its motion and resulting estimates of the masses of the two stars have been a subject of debate for the better part of the last century.Led by Howard Bond (Pennsylvania State University and the Space Telescope Science Institute), a team of astronomers has now analyzed two decades of Hubble observations of the system, combined with historical, ground-based observations dating back to the 19th century. Bond and collaborators used these data to precisely measure the orbital elements of Procyon and obtain dynamical masses of the two stars.Surprising MixingRelative orbit of Procyon B around Procyon A. The red curve is the authors fit to the orbit, and the open blue circles are positions predicted by the orbital elements found. The black dots are the HST observations of Procyon B. The open green and turquoise circles are the (significantly less precise!) historical, ground-based observations. [Bond et al. 2015]The team reports that this system orbits once every 40.8 years. They find masses for the two stars of 1

  19. A geomechanical model of a sinkhole formation

    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

  20. Grasshoppers as a food source? A review

    Paul, A.

    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.

  1. A reductive coupling strategy towards ripostatin A

    Kristin D. Schleicher

    2013-07-01

    Full Text Available Synthetic studies on the antibiotic natural product ripostatin A have been carried out with the aim to construct the C9−C10 bond by a nickel(0-catalyzed coupling reaction of an enyne and an epoxide, followed by rearrangement of the resulting dienylcyclopropane intermediate to afford the skipped 1,4,7-triene. A cyclopropyl enyne fragment corresponding to C1−C9 has been synthesized in high yield and demonstrated to be a competent substrate for the nickel(0-catalyzed coupling with a model epoxide. Several synthetic approaches toward the C10−C26 epoxide have been pursued. The C13 stereocenter can be set by allylation and reductive decyanation of a cyanohydrin acetonide. A mild, fluoride-promoted decarboxylation enables construction of the C15−C16 bond by an aldol reaction. The product of this transformation is of the correct oxidation state and potentially three steps removed from the targeted epoxide fragment.

  2. Birth of a theorem a mathematical adventure

    Villani, Cédric

    2015-01-01

    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.

  3. 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.

  4. PSYCHOTHERAPY FOR A SPORTS PERSON: A REVIEW

    Kumudlata Singh

    2015-04-01

    Full Text Available Sports is all forms of usually competitive physical activity which, through casual or organized participation, aim to use, maintain or improve physical ability and skills while providing entertainment to participants, and in some cases, spectators. Sport participation can contribute to the development of social skills and self esteem, emotional well-being, social connectedness, and lead to a reduction in stress and improved mental health (Steptoe & Butler, 1996; Bailey, 2006; Asztalos et al., 2008; Armstrong & Oomen-Early, 2009. However, at higher levels of athletics, and in collegiate settings where pressures placed on the athlete are not just sport-related, athletes may be at risk for developing emotional and psychological problems. Sports psychology concerns with both psychological factors that influence participation and performance in sport and exercise as well as psychological effects derived from them. This is a study in the theory and philosophy of Psychotherapy. The focus is on the psychotherapeutic technique of reframing – a technique for helping sportsmen to see their situation in a new light, from a new perspective. Psychotherapy is the treatment by psychological means of the problem of an emotional nature, in which a trained person deliberately establishes a professional relationship with the patient.

    This paper uses data from the British Household Panel Survey (BHPS) and the British 1970 Cohort Study (BCS70) to investigate the family background and childhood factors that are associated with having a child as a teenager. The advantage of combining results from these two sets of data is that the BHPS analyses are restricted to a few background factors while the BCS70 analyses have far more. However, the results obtained from the BHPS data are reasonably replicated with the BCS70 data in tha...

    We consider a model of interface growth in two dimensions, given by a height function on the sites of the one--dimensional integer lattice. According to the discrete time update rule, the height above the site $x$ increases to the height above $x-1$, if the latter height is larger; otherwise the height above $x$ increases by 1 with probability $p_x$. We assume that $p_x$ are chosen independently at random with a common distribution $F$, and that the initial state is such that the origin is fa...

  8. Radon: a friend or a foe?

    Radon has two facets. On the one hand, it poses grave health hazards to not only uranium miners but also people living in normal houses and buildings. On the other hand, it helps in mineral exploration, earthquake prediction, study of volcanic activities, and search for geothermal energy sources. Some of the characteristics of radon are now well known, while others are yet to be explored. It has proved to be a good friend and a powerful enemy at the same time. This paper is a brief introduction of the potential benefits and possible threats of radon and its daughters. (author)
