From this argument, unfolds reading a cinema that is made in and by the displacement, transit through everyday, openness to chance, contingency; not part of a space-time unit but fragments - which fragment itself as ethical possibility in the face of otherness; passages, traces, traces of a gesture. Designing the intimate scenes in public in a kind of continuous and unpretentious celebration of everyday life, the family. Cinema in exile, cinema-asylum – at the same time, survival and suspension of memory, body and language shelter, place of the meeting, which always seems to draw the possibility, opening for the invention of a new space, inedited, space- life, space-art without borders.

    Burgui Burgui, Mario

    2015-01-01

    This article discusses three of the problems that the German philosopher Hans Jonas studied. The first one addresses the need for a specific ethic dedicated to the moral dimension of environmental problems, from a different perspective to the traditional. The second problem is crucial in the discussion on environmental ethics: the value of the nature. Does the nature have an intrinsic value or an instrumental value only (to satisfy the interests of the human being)? The thesis of Jonas, which claimed that nature is a good in itself, were further elaborated here. And the third problem is the derivation of moral norms and the role of man in this ethic that recognizes a good in itself in nature. According to Jonas, the human being is not diminished by recognizing the intrinsic value of nature, since the man's uniqueness and value are unquestionable. From these three central issues, the paper highlights the importance of seeking the links between bioethics and environmental ethics to address the current environmental, social and economic crisis.

    We argue that the extended Nambu-Jona-Lasinio model of hadrons can be be probed and constrained in a nontrivial way via QCD sum rules. While there arise rather restrictive bounds on the strength of the effective four-fermion interaction in the vector channel, introduction of the four-fermion interaction in the pseudoscalar channel could resolve a long standing puzzle of QCD sum rules. We speculate also on possible connection between effective four-quark interactions describing the low-energy ...

    2017-01-01

    We present a lattice study of a Nambu Jona-Lasinio (NJL) model using Wilson fermions. Four fermion interactions are a natural part of several extensions of the Standard Model, appearing as a low energy description of a more fundamental theory. In models of dynamical electroweak symmetry breaking they are used to endow the Standard Model fermions with masses. In infrared conformal models these interaction, when sufficiently strong, can alter the dynamics of the fixed point, turning the theory into a (near) conformal model with desirable features for model building. As a first step toward the nonperturbative study of these models, we study the phase space of the ungauged NJL model.

  17. Mesonic states in the generalised Nambu-Jona-Lasinio theories

    Science.gov (United States)

    Nefediev, A. V.; Ribeiro, J. E. F. T.

    2005-04-01

    For any Nambu-Jona-Lasinio model of QCD with arbitrary nonlocal, instantaneous, quark current-current confining kernels, we use a generalised Bogoliubov technique to go beyond BCS level (in the large-NC limit) so as to explicitly build quark-antiquark compound operators for creating/annihilating mesons. In the Hamiltonian approach, the mesonic bound-state equations appear (from the generalised Bogoliubov transformation) as mass-gap-like equations which, in turn, ensure the absence, in the Hamiltonian, of mesonic Bogoliubov anomalous terms. We go further to demonstrate the one-to-one correspondence between Hamiltonian and Bethe-Salpeter approaches to non-local NJL-type models for QCD and give the corresponding "dictionary" necessary to "translate" the amplitudes built using the graphical Feynman rules to the terms of the Hamiltonian, and vice versa. We comment on the problem of multiple vacua existence in such type of models and argue that mesonic states in the theory should be prescribed to have an extra index — the index of the replica in which they are created. Then the completely diagonalised Hamiltonian should contain a sum over this new index. The method is proved to be general and valid for any instantaneous quark kernel.

This case study clearly shows the difficulties which correlative Bible Didactics have to face. However, it also illustrates the chances of working with the book of Jona on an intertextual basis. Based on this case study, the theoretical main features of intertextual exegesis shall be presented here. This should then lead to the development of requirements and challenges for intertextually oriented learning processes.

Por esse motivo, torna-se um imperativo buscar meios de controle sobre a técnica mesma, aquilo que Jonas denomina a busca de um poder sobre o poder; do contrário, o ser humano, objeto da razão instrumental, estaria subscrevendo sua própria extinção.

The effective interaction between quarks is symmetric under chiral SU(3){sub L}xSU(3){sub R} and incorporates a U(1){sub A}-breaking six-point interaction as suggested by 't Hooft. We coencentrate on the evaluation of masses and decay constants of pseudoscalar mesons, with special emphasis on the underlying symmetry breaking patterns.

    We study the three-flavor Nambu–Jona-Lasinio model with various regularization procedures. We perform parameter fitting in each regularization and apply the obtained parameter sets to evaluate various physical quantities, several light meson masses, decay constant and the topological susceptibility. The model parameters are adopted even at very high cutoff scale compare to the hadronic scale to study the asymptotic behavior of the model. It is found that all the regularization methods except for the dimensional one actually lead reliable physical predictions for the kaon decay constant, sigma meson mass and topological susceptibility without restricting the ultra-violet cutoff below the hadronic scale.

    An explicit evaluation of the two pion transverse momentum dependent parton distributions at leading twist is presented, in the framework of the Nambu-Jona Lasinio model with Pauli-Villars regularization. The transverse momentum dependence of the obtained distributions is generated solely by the dynamics of the model. Using these results, the so called generalized Boer-Mulders shift is studied and compared with recent lattice data. The obtained agreement is very encouraging, in particular because no additional parameter has been introduced. A more conclusive comparison would require a precise knowledge of the QCD evolution of the transverse momentum dependent parton distributions under scrutiny.

    1989-12-19

    In this thesis the author tried to decribe important low-energy phenomena of the strong interactions by means of the Nambu-Jona-Lasinio model. The effective quark-quark interaction was thereby constructed in accordance with the basing symmetries and conserved currents of the QCD; the model possesses especially chiral SU(3){sub L} x SU(3){sub R} symmetry. In the framework of this approach properties of the quarks and the light mesons were studied. In the calculations for instance the Hartree-Fock approach for the quark propagator was used. Properties of the mesons were determined in the framework of a RPA calculation by solution of the Bethe-Salpeter equation for the quark-antiquark scattering matrix. All questions, which were treated here, concern aspects of the symmetry breaking of the QCD: At the one hand the explicit breaking of the chiral symmetry by finite, if also small quark current masses. Thereby was assumed that these can be described as low perturbation of the chiral limit of massless quarks; furthermore the breaking of the U(1){sub A} symmetry observed in nature. It was tried to regard this anomaly property of the QCD by an additional flavor-mixing and U(1){sub A} breaking determinant interaction. The last and most important point finally is the spontaneous breaking of the chiral symmetry and the generation of quark condensates in the QCD ground state by the interaction dynamics. (orig./HSI).

    The phenomenon of inverse magnetic catalysis of chiral symmetry in QCD predicted by lattice simulations can be reproduced within the Nambu-Jona-Lasinio model if the coupling G of the model decreases with the strength B of the magnetic field and temperature T. The thermo-magnetic dependence of G(B, T) is obtained by fitting recent lattice QCD predictions for the chiral transition order parameter. Different thermodynamic quantities of magnetized quark matter evaluated with G(B, T) are compared with the ones obtained at constant coupling, G. The model with G(B, T) predicts a more dramatic chiral transition as the field intensity increases. In addition, the pressure and magnetization always increase with B for a given temperature. Being parametrized by four magnetic-field-dependent coefficients and having a rather simple exponential thermal dependence our accurate ansatz for the coupling constant can be easily implemented to improve typical model applications to magnetized quark matter.

  13. A renovação da teleologia em Hans Jonas:

    Directory of Open Access Journals (Sweden)

    Wendell Evangelista Soares Lopes

    2011-05-01

    Full Text Available O presente trabalho visa elucidar a renovaçáo da teleologia no pensamento de Hans Jonas, mostrando como esta ocupa aí duas funções centrais, a saber: pensar uma nova ontologia que atenda de forma mais exata à construçáo de um universo psicofísico e em vir-a-ser; e pensar o dever-ser da humanidade enquanto telos e valor absoluto no processo evolutivo do Ser. Para alcançarmos nosso objetivo, primeiro explicitaremos que o que Jonas designa por "enigma da subjetividade" é o problema fundamental da ontologia, e que a filosofia moderna fracassa diante de tal problema, exigindo assim a reabilitaçáo – e renovaçáo – de uma concepçáo teleológica do ser. Depois mostraremos que essa renovaçáo da teleologia – que pode certamente ser designada de "neo-finalismo" – define o finalismo como intrínseco náo só aos seres individuais, mas ao próprio devenir do mundo, onde o homem seria a própria realizaçáo última de uma possibilidade latente no interior de tal processo evolutivo da substância universal. Com isso, resultaria um princípio da ética que náo estaria fundado nem na autonomia do Eu, nem nas necessidades da comunidade, mas antes no próprio caráter teleológico do processo evolutivo da natureza – o homem assumindo aí um valor absoluto por justamente ser o telos – entenda-se: "qualidade final" – de tal processo. Quer isto dizer, a teleologia jonasiana visa por fim responder sobre o bem que é a humanidade, que se firmaria assim como o próprio fundamento da ética.

    2017-10-01

    In the present investigation, the application of the Poliak-Jonas criterion in the semi-solid state has been evaluated. The evolution of grains by dynamic recrystallization during semi-solid forming was studied using electron backscatter diffraction (EBSD) analysis. The strain rate in the solid phase for each strain in terms of the overall strain rate, as well as the liquid fraction, was calculated based on the Gurson model. The numerical investigation revealed that the preliminaries of the Poliak-Jonas criterion are almost satisfied in the semi-solid deformation of alloys at low and moderate strain rates. However, there is less reliability regarding the criterion at high values of strain rates, where commonly used in industrial applications.

  16. The ethics of human condition in the age of technological civilization. Back and forth with Heidegger and Jonas.

    2009-07-01

    Full Text Available The ethical dimension of the human condition in our times takes increasingly more space in current philosophical discussions. In this context, the ethical principle of responsibility has been widely discussed, particularly by authors who work on the ethical implications of modern technology. In his essay on ethics for the technological age, Hans Jonas proposes to base ethics on a principle of responsibility, taking into account that we live in the age of technological civilization. The present paper explores the origins and sources of Jonas’ principle of responsibility, focusing on the influence of his teacher Martin Heidegger on Jonas’s work. The paper analyses the intrinsic and intriguing relationship between Heidegger’s ontological concept of “care” [Sorge] and the idea or responsibility in Jonas, and it examines further the current discussion on the possibility of an ethical foundation for the techno scientific civilization.

    We investigate the properties of constituent quarks, i.e. quarks dressed by their strong interactions, in a generalized Nambu-Jona-Lasinio model with N{sub f}=3 flavours. In the Hartree-Fock approximation, the step from structureless current quarks to massive constituent quarks is made through dynamical mass generation which implies spontaneous chiral symmetry breaking. We study, in particular, the quark scalar, vector and axial vector currents within this framework. We demonstrate that, a low energy and momentum transfers, single valence quarks are strongly screened by quark-antiquark polarization effects. For the electromagnetic currents, we recover relationships familiar from the vector meson dominance model. For the axial current, screening by J{sup {pi}}=1{sup +} quark-antiquark modes leads to an effective quark axial vector constant g{sub A}<1 which satisfies the Goldberger-Treiman relation at the quark level. The spin content of the proton is also discussed in this framework. We calculate quark magnetic moments and electromagnetic form factors and discuss their related sizes. (orig.).

    Full Text Available In this work, we adopt the Nambu–Jona-Lasinio (NJL model that ensures the nuclear matter saturation properties to study the density dependence of the symmetry energy. With the interactions constrained by the chiral symmetry, the symmetry energy shows novel characters different from those in conventional mean-field models. First, the negative symmetry energy at high densities that is absent in relativistic mean-field (RMF models can be obtained in the RMF approximation by introducing a chiral isovector–vector interaction, although it would be ruled out by the neutron star (NS stability. Second, with the inclusion of the isovector–scalar interaction the symmetry energy exhibits a general softening at high densities even for the large slope parameter of the symmetry energy. The NS properties obtained in the present NJL model can be in accord with the observations. The NS maximum mass obtained with various isovector–scalar couplings and momentum cutoffs is well above the 2M⊙, and the NS radius obtained well meets the limits extracted from recent measurements. In particular, the significant reduction of the canonical NS radius occurs with the moderate decrease of the slope of the symmetry energy.

    We extend the SU(3) Nambu-Jona-Lasinio (NJL) model to include two types of vector interaction. Using these two types of vector interaction in NJL model, we study the quark symmetry free energy in asymmetric quark matter, the constituent quark mass, the quark fraction, the equation of state (EOS) for β-equilibrium quark matter, the maximum mass of QSs at finite temperature, the maximum mass of proto-quark stars (PQSs) along the star evolution, and the effects of the vector interaction on the QCD phase diagram. We find that comparing zero temperature case, the values of quark matter symmetry free energy get larger with temperature increasing, which will reduce the difference between the fraction of u, d and s quarks and stiffen the EoS for β-equilibrium quark matter. In particular, our results indicate that the maximum masses of the quark stars increase with temperature because of the effects of the quark matter symmetry free energy, and we find that the heating(cooling) process for PQSs will increase (decrease) the maximum mass within NJL model.

    We study the correlation length between test quarks with the same electric and color charges in the Nambu-Jona-Lasinio model, considering thermal and magnetic effects. We extract the correlation length from the quark correlation function. The latter is constructed from the probability amplitude to bring a given quark into the plasma once a previous one with the same quantum numbers is placed at a given distance apart. For temperatures below the transition temperature, the correlation length starts growing as the field strength increases to then decrease for large magnetic fields. For temperatures above the pseudocritical temperature, the correlation length continues increasing as the field strength increases. We found that such behavior can be understood as a competition between the tightening induced by the classical magnetic force versus the random thermal motion. For large enough temperatures, the increase of the occupation number contributes to the screening of the interaction between the test particles. The growth of the correlation distance with the magnetic field can be understood as due to the closer proximity between one of the test quarks and the ones popped up from the vacuum, which in turn appear due to the increase of the occupation number with the temperature.

    The present work consists in a 1/N expansion of extended version of the SU(3) Nambu-Jona-Lasinio model in the context of the Functional Integral. The gap equations, meson propagators, triangle diagram, etc, appear quite naturally as different orders in the expansion. The new features of this approach is the inclusion of high order corrections in the 1/N leading orders, which have never included in the previous one. The method also allows for the construction of a chiral Lagrangian of interacting mesons based on the SU(3) NJL model, here obtained for the first time. (author) 32 refs., 11 figs., 5 tabs.

  3. Cosmological implications of Nambu-Jona-Lasinio model with a dynamical coupling

    Science.gov (United States)

    Quintanar, G. Leonardo; de La Macorra, Axel

    We study the cosmological implications of the Nambu-Jona-Lasinio (NJL) model when the coupling constant is field dependent. The NJL model has a four-fermion interaction describing two different phases due to quantum interaction effects and determined by the strength of the coupling constant g. It describes massless fermions for weak coupling and a massive fermions and strong coupling, where a fermion condensate is formed. In the original NJL model, the coupling constant g is indeed constant, and in this work we consider a modified version of the NJL model by introducing a dynamical field dependent coupling motivated by string theory. The effective potential as a function of the varying coupling (aimed to implement a natural phase transition) is seen to develop a negative divergence, i.e. becomes a “bottomless well” in certain limit region. Although we explain how an lower unbounded potential is not necessarily unacceptable in a cosmological context, the divergence can be removed if we consider a mass term for the coupling like field. We found that for a proper set of parameters, the total potential obtained has two minima, one located at the origin (the trivial solution, in which the fluid associated with the fields behave like matter); and the other related to the nontrivial solution. This last solution has three possibilities: (1) if the minimum is positive Vmin > 0, the system behaves as a cosmological constant, thus leading eventually to an accelerated universe; (2) if the minimized potential vanishes Vmin = 0, then we have matter with no acceleration; (3) finally a negative minimum Vmin universe with a flat geometry. Therefore, a possible interpretation as dark matter (DM) or dark energy (DE) is allowed among the behaviors implicated in the model.

    In spite of the apparent limitations of the model, in recent years there have been many applications of the Nambu--Jona-Lasinio (NJL) model in the study of hadron structure and in the study of the behavior of nuclear matter at finite temperature and density. A number of researchers have studied a generalized SU(3) version of the NJL model. For example, Vogl, Lutz, Klimt, and Weise (Nucl. Phys. A516 469 (1990)) have performed extensive calculations that include a calculation of a scalar form factor of a constituent quark, {ital F}{sub {ital s}}({ital q}{sup 2}), and a calculation of a quark sigma term {sigma}{sub {ital q}}. (In their work, the latter quantity is related to the nucleon sigma term {sigma}{sub {ital N}} as in a constituent quark model: {sigma}{sub {ital N}}=3{sigma}{sub {ital q}}.) These calculations are made in what may be termed a sigma-dominance approximation. In the work reported here, we review the important role played by the nucleon sigma term in understanding the behavior of the quark condensate in the presence of matter. We make use of the original SU(2) version of the NJL model to study how various quark properties are modified when we take into account the dressing of the constituent quarks by the pion, the Goldstone boson of the model. We calculate the quark self-energy arising from emission and absorption of a pion and also show how the calculation of the scalar form factor of the quark and {sigma}{sub {ital q}} are modified due to the coupling of the quark to the pion. The correction terms considered here serve to reduce the value of {sigma}{sub {ital q}} by a small amount relative to the value obtained in the simplest version of the sigma dominance model. For example, for a Euclidean momentum cutoff, {Lambda}=1050 MeV, the uncorrected result is {sigma}{sub {ital N}}=54.6 MeV.

These calculations are made in what may be termed a sigma-dominance approximation. In the work reported here, we review the important role played by the nucleon sigma term in understanding the behavior of the quark condensate in the presence of matter.

For example, for a Euclidean momentum cutoff, Λ=1050 MeV, the uncorrected result is σN=54.6 MeV. That value is then reduced to σN=51.5 MeV, if the corrections due to the pion ``dressing'' are included. It is also found that the residue at the quasiparticle pole of the quark propagator Z is about 0.86 when the coupling to the pion field is taken into account.

  7. A renovação da teleologia em Hans Jonas: da biologia filosófica aos fundamentos da ética

    Directory of Open Access Journals (Sweden)

    Wendell Evangelista Soares Lopes

    2010-12-01

    Full Text Available The present paper aims to elucidate the renewal of teleology in the thought of Hans Jonas showing how it takes up two central functions, namely: to think a philosophical biology – or ontology – that more accurately meets the construction of a coming-to-be and psychophysical universe; and to think the ought-to-be of humanity as the telos and absolute value in the evolutionary process of Being. To accomplish our goal, we explain first that what Jonas calls the “riddle of subjectivity” is the basic problem of ontology, and that modern philosophy fails to respond to it, thus requiring a rehabilitation – and renewal – of a teleological conception of being. Then we will show that this renewal of teleology, that can be called “neo-finalism”, defines finalism as intrinsic not only to individual beings, but also to the devenir of the world itself, where man would be the very ultimate realization of a latent possibility within this evolutionary process of the universal substance. Hence would result a principle of ethics which is ultimately grounded neither in the autonomy of the self nor in the needs of community, but in the teleological character of the evolutionary process of nature itself – man as the “final quality”, and thus the absolute value, of such a process. That is to say, for Jonas teleology aims to finally answer what is the good about humanity, who would sign as well as the very foundation of ethics.

Um dos seus alunos, Hans Jonas, tenta de forma original, mas não livre de equívocos, apresentar uma ética válida para a civilização tecnológica. Segundo Jonas, a situação do homem e o contexto de qualquer propósito ético estariam hoje fundamentalmente mudados; uma ética tradicional não estaria mais à sua altura.

  9. Interplay Between Quark-Antiquark and Diquark Condensates in Vacuum in a Two-Flavor Nambu-Jona-Lasinio Model

    By means of a relativistic effective potential, we analytically research competition between the quark-antiquark condensates langlebar qqrangle and the diquark condensates langleqqrangle in vacuum in ground state of a two-flavor Nambu-Jona-Lasinio (NJL) model and obtain the GS-HS phase diagram, where GS and HS are the respective four-fermion coupling constants in scalar quark-antiquark channel and scalar color anti-triplet diquark channel. The results show that, in the chiral limit, there is only the pure langlebar qqrangle phase when GS/HS>2/3, and as GS/HS decreases to 2/3>GS/HS>=0 one will first have a coexistence phase of the condensates langlebar qqrangle and langleqqrangle and then a pure langleqqrangle phase. In non-zero bare quark mass case, the critical value of GS/HS at which the pure langlebar qqrangle phase will transfer to the coexistence phase of the condensates langlebar qqrangle and langleqqrangle will be less than 2/3. Our theoretical results, combined with present phenomenological fact that there is no diquark condensates in the vacuum of QCD, will also impose a real restriction to any given two-flavor NJL model which is intended to simulate QCD, i.e. in such model the resulting smallest ratio GS/HS after the Fierz transformations in the Hartree approximation must be larger than 2/3. A few phenomenological QCD-like NJL models are checked and analyzed.

  10. A responsabilidade como princípio ético em H. Jonas e E. Levinas: uma aproximação

    Kuiava, Evaldo Antônio

    2006-01-01

    Full Text Available A responsabilidade enquanto princípio ético, embora seja evocada pelos filósofos clássicos, desde a antigüidade ao existencialismo, assume novas perspectivas a partir do pensamento de Hans Jonas e Levinas. Ambos a colocam como centro da ética. Com Jonas a responsabilidade não é mais centrada no passado e no presente. A sua preocupação é com o futuro da humanidade, com as gerações futuras e com a sobrevivência das mesmas. Diferente de Platão, Jonas não está preocupado com a eternidade, mas com o tempo vindouro, compatível com a era da ciência e da tecnologia, cuja responsabilidade passa a ser o alicerce, o princípio orientador para as decisões que possam interferir nas diferentes formas de vida. Levinas, por sua vez, também se afasta da tradição filosófica na medida que não aceita mais a tese de que a responsabilidade é decorrente da liberdade. A responsabilidade não nasce de uma boa vontade, de um sujeito autônomo que quer livremente se comprometer com o outro ser. Ela nasce como resposta a um chamado. A responsabilidade é o fundamento primeiro e essencial da estrutura ética, a qual não aparece como suplemento de uma base existencial prévia. Aquém do ser se encontra uma subjetividade capaz de escutar a voz, sem palavras de um dizer original, e aponta para uma outra dimensão do eu. Prévio ao ato de consciência, anterior ao sujeito intencional, o eu já responde a um chamado. A responsabilidade pelo outro ser precede a representação conceitual ou a mediação de um mandamento ético. Ela é obediência a uma vocação, a uma eleição pelo bem além do ser. A responsabilidade determina a liberdade do eu, pois esta não consegue mais se justificar por ela mesma. Responsibility qua ethical principle, however evoked by classical philosophers from Antiquity through existentialism, assumes new perspectives since the contributions of Hans Jonas and Levinas. Both place it at the center of ethics. With Jonas

    Objectives: In the use of activated carbon beds as adsorbents for various types of organic vapor in respirator gas filters, water adsorption of the bed and test gas humidity are expected to alter the accuracy in the estimation of breakthrough data. There is increasing interest in the effects of moisture on estimation methods, and this study has investigated the effects with actual breakthrough data. Methods: We prepared several activated carbon beds preconditioned by equilibration with moisture at different relative humidities (RH=40%-70%) and a constant temperature of 20°C. Then, we measured breakthrough curves in the early region of breakthrough time for 10 types of organic vapor, and investigated the effects of moisture on estimation using the Wheeler-Jonas equation, the simulation software NIOSH MultiVapor™ 2.2.3, and RBT (Relative Breakthrough Time) proposed by Tanaka et al. Results: The Wheeler-Jonas equation showed good accordance with breakthrough curves at all RH in this study. However, the correlation coefficient decreased gradually with increasing RH regardless of type of organic vapor. Estimation of breakthrough time by MultiVapor showed good accordance with experimental data at RH=50%. In contrast, it showed discordance at high RH (>50%). RBTs reported previously were consistent with experimental data at RH=50%. On the other hand, the values of RBT changed markedly with increasing RH. Conclusions: The results of each estimation method showed good accordance with experimental data under comparatively dry conditions (RH≤50%). However, there were discrepancies under high humidified conditions, and further studies are warranted. PMID:27725483

We consider the intermediate states with π0 and σ as hadrons in the frame-work of the Nambu-Jona-Lasinio (NJL) model. The contribution of the π0γ state is in agreement with results obtained in previous theoretical considerations as well as with the experimental data a_μ ^{π _0 γ } ≈ 4.5 × 10^{ - 10} , besides we estimate a {μ/ηγ} = 0.7 × 10-10, a {μ/σγ} ˜ 1.5 × 10-11, a_μ ^{π ^ + π ^ - γ } ˜ 3.2 × 10^{ - 10} . We also discuss the light-by-light (LbL) mechanism with a {μ/ lbl } = 10.5 × 10-10.

    The Nambu-Jona-Lasinio model with two flavors, three colors, and diquark interactions is analyzed in the context of optimized perturbation theory (OPT). Corrections to the thermodynamical potential that go beyond the large-Nc (LN) approximation are taken into account, and the region of the phase diagram corresponding to intermediate chemical potentials and very low temperatures is explored. The simultaneous presence of both the quark-antiquark and diquark condensates can cause the system to behave as a fluid composed of a Bose-Einstein condensate (BEC) or a color superconductor one, in the form of a Bardeen-Cooper-Schrieffer (BCS) superfluid. The BEC-BCS crossover is then studied in the nonperturbative OPT scheme. The results obtained in the context of the OPT method are then contrasted with those obtained in the LN approximation. We show that there are values for the coupling constants related to quark-quark and quark-antiquark interactions where the corrections beyond LN brought by the OPT method can influence the behavior of the diquark condensate and the effective quark mass as a function of the baryon chemical potential. These changes in the behavior of the phase structure of the model modify the location of the critical point related to the phase structure as a whole of the model. Also, when we impose the color neutrality condition, our results show that the nature of the phase transition can change as well, shifting the ratio of the quark-antiquark and quark-quark interactions to higher values in the OPT case as compared to the LN approximation.

    This thesis presents a detailed overview of the thermodynamical properties of the model of Nambu and Jona-Lasinio. In fact, this model can be interpreted as a low energy approximation of QCD. The NJL model has the advantage to be solvable at finite temperature and density. Comparison with QCD lattice calculations show that the NJL model reproduces correctly the feature of chiral symmetry breaking and restoration. We present the chiral phase diagram of the NJL model for three flavors and study the influence of the parameters on the order of the phase transition. The properties of the mesons in a hot and dense medium are another topic of this thesis. We discuss the behaviour of the chiral partners and the influence of the symmetries. A point of special interest are the masses of the kaons in a dense medium. We compare the masses of the kaons with other models like RMF and ChPT. The last part of the thesis is devoted to the low temperature - high density region of the QCD phase diagram. In this region, the formation of a diquark condensate and a superconducting phase are expected. We discuss the structure of the diquark condensate and present the results of the numerical calculations at finite temperature and density. (author)

It argues that the reader is persuaded to see Jonah’s flight from Yahweh and his commission ultimately leading to his ending up behind the bars of death (2:7b. Embedded in fictitious and mythological descriptions is Yahweh who delivered Jonah from the pit of death, namely Sheol (2:7c. Resurrection faith narratives in the Second Testament confirm these perspectives in the First Testament.

    The purpose of this study was to investigate the healing process of wounded skin following the application of cyanoacrylate or a 4-(2-methacryloxyethyl) trimellitic anhydride/methyl methacrylate-tributylborane resin (4-META resin). Those materials were applied to skin wound areas in rats, and the regenerating tissues were biopsied and examined at days 1, 3, 5, 7, and 14. Paraffin-embedded specimens were sectioned and stained with hematoxylin and eosin or with Azan-Mallory stain. Sections were also immunohistochemically stained with Pan-cytokeratin and CD68 antibodies. In cyanoacrylate-treated wounds, CD68-positive cells were observed in the connective tissue and their number increased up to day 5. The wound surface was completely covered by epithelial tissue at day 14. In 4-META resin-treated wounds, CD68-positive cells appeared in the soft-tissue hybrid layer (STHL) and epithelial tissue had migrated under the STHL by day 5. The wound surface was completely covered by epithelial tissue at day 7. CD68-positive cells were distributed over the entire area of the cyanoacrylate-treated wounds, but accumulated under the STHL in the 4-META resin-treated wounds. In conclusion, the results suggest that covering skin defects with a 4-META resin is an effective strategy to promote wound healing compared to cyanoacrylate. © 2015 Wiley Periodicals, Inc.

  11. Scanning thermal lithography of tailored tert-butyl ester protected carboxylic acid functionalized (meth)acrylate polymer platforms.

    2011-10-01

    In this paper, we report on the development of tailored polymer films for high-resolution atomic force microscopy based scanning thermal lithography (SThL). In particular, full control of surface chemical and topographical structuring was sought. Thin cross-linked films comprising poly(tert-butyl methacrylate) (MA(20)) or poly(tert-butyl acrylate) (A(20)) were prepared via UV initiated free radical polymerization. Thermogravimetric analysis (TGA) and FTIR spectroscopy showed that the heat-induced thermal decomposition of MA(20) by oxidative depolymerization is initially the primary reaction followed by tert-butyl ester thermolysis. By contrast, no significant depolymerization was observed for A(20). For A(20) and MA(20) (at higher temperatures and/or longer reaction times) the thermolysis of the tert-butyl ester liberates isobutylene and yields carboxylic acid groups, which react further intramolecularly to cyclic anhydrides. The values of the apparent activation energies (E(a)) for the thermolysis were calculated to be 125 ± 13 kJ mol(-1) and 116 ± 7 kJ mol(-1) for MA(20) and A(20), respectively. Both MA(20) and A(20) films showed improved thermomechanical stability during SThL compared to non cross-linked films. Carboxylic acid functionalized lines written by SThL in A(20) films had a typically ~10 times smaller width compared to those written in MA(20) films regardless of the tip radius of the heated probe and did not show any evidence for thermochemically or thermomechanically induced modification of film topography. These observations and the E(a) of 45 ± 3 kJ mol(-1) for groove formation in MA(20) estimated from the observed volume loss are attributed to oxidative thermal depolymerization during SThL of MA(20) films, which is considered to be the dominant reaction mechanism for MA(20). The smallest line width values obtained for MA(20) and A(20) films with SThL were 83 ± 7 nm and 21 ± 2 nm, whereas the depth of the lines was below 1 nm, respectively.

  16. IONOTOMO: A new approach for ionospheric tomography using OTH radar

    Science.gov (United States)

    Roy, Corinna; Occhipinti, Giovanni; Boschi, Lapo; Moliné, Jean-Philippe

    2013-04-01

    Most of the recent methods in ionospheric tomography are based on the inversion of the Total Electron Content (TEC) measured by ground-based GPS receivers [e.g., Garcia et al. 2008]. As a consequence of the high frequency of the GPS, the electron density structure is principally well reconstructed at the F2 region, where the ionosphere reaches the maximum of ionization, neglecting the lower ionosphere. Here, we develop a new 3D ionospheric tomography method based on the full analysis of over-the-horizon (OTH) radar data. Previous studies in ionospheric tomography by OTH radar (Fridman and Fridman, 1994; Ruelle and Landeau, 1994; Landeau et al., 1997; Fridman, 1998) are all based on the inversion of the leading edge echo curve, consequently an important amount of valuable information present in the data is necessarily neglected. To overcome this limit, we set up a new method, based on the ray-tracing tool TDR [Occhipinti, 2006], to invert the propagation time of electromagnetic waves emitted by monostatic OTH radars. The major advance of our methodology is taking into account, numerically and jointly, not only the speed variation of EM wave induced by the electron density variation (solved analytically with a linear inversion) but also the perturbation in the raypath (nonlinear numerical method). As the present problem is an ill posed problem we calculate the matrix inversion numerically, using a regularisation method (Tikhonov, 1963). We determine the best regularisation parameter using the Lcurve method (Hansen, 2000). We present here the originality and the advantage of our method with a full set of synthetic benchmark highlighting the sensitivity of our tomography to the plasma heterogeneities. Some preliminary test on real data will be presented with a full coverage over Europe. Indeed, the ionospheric tomography by OTH radar, jointly with GPS, could open new exciting perspective in the plasma density estimation with a good resolution to the entire ionosphere

    UNAVCO, in conjunction with JPL, is responsible for monitoring the 62 GNSS permanent stations, which include 88 GPS receivers, which comprise the NASA Global GNSS Network (GGN). These sites represent approximately 16% of the ~400 International GNSS Service (IGS) stations, and they provide a globally distributed GNSS network to support NASA operations and its commitments to GGOS. UNAVCO provides data flow monitoring, trouble-shooting, station installation, maintenance, as well as engineering services to improve the capabilities and performance of station infrastructure. Activities this past year include the installation of a geodetic quality wellhead monument for the new SEY2 station to replace SEY1, which is mounted on a UCSD seismic station in the Seychelles Islands. SEY1 will be removed soon to accommodate planned maintenance and upgrades by UCSD. Data from both SEY1 and SEY2 are being collected concurrently until maintenance begins. MRTG (Multi Router Traffic Grapher), a tool to aid in characterizing bandwidth usage and to identify communications problems, is now being used to monitor data throughput at 7 stations where VSAT or radio telemetry are used, including: ABPO; AREQ; FALK; GUAM; HARV; ISPA; QUIN; and STHL. Aging computers are being replaced with new hardware running Linux CentOS. These are semi-ruggedized low power solid-state systems built to endure challenging environments. With the aid of on-site collaborators, systems are now deployed at: FALK; CUSV; KELY; STHL; SANT; and ZAMB. Last, 4 new GPS stations were deployed for NASA's Space Geodesy Project (SGP); three of which (KOKF, KOKG, and KOKR) are located at Koke'e Park Geophysical Observatory on Kauai, Hawai'i, and HAL1 at the Haleakala observatory complex on Maui, Hawai'i. A campaign system was set up at Koke'e in order to sample data quality to determine if an additional station would be viable. Planning is ongoing for deployment of several new stations next year at McDonald Observatory (TX).

  7. Two-temperature models for nitrogen dissociation

    Science.gov (United States)

    da Silva, M. Lino; Guerra, V.; Loureiro, J.

    2007-12-01

    Accurate sets of nitrogen state-resolved dissociation rates have been reduced to two-temperature (translational T and vibrational Tv) dissociation rates. The analysis of such two-temperature dissociation rates shows evidence of two different dissociation behaviors. For Tv 0.3 T dissociation proceeds predominantly form the near-dissociative vibrational levels, with an abrupt change of behavior at Tv = 0.3 T. These two-temperature sets have then been utilized as a benchmark for the comparison against popular multitemperature dissociation models (Park, Hansen, Marrone-Treanor, Hammerling, Losev-Shatalov, Gordiets, Kuznetsov, and Macheret-Fridman). This has allowed verifying the accuracy of each theoretical model, and additionally proposing adequate values for any semi-empirical parameters present in the different theories. The Macheret-Fridman model, who acknowledges the existence of the two aforementioned dissociation regimes, has been found to provide significantly more accurate results than the other models. Although these different theoretical approaches have been tested and validated solely for nitrogen dissociation processes, it is reasonable to expect that the general conclusions of this work, regarding the adequacy of the different dissociation models, could be extended to the description of arbitrary diatomic dissociation processes.

    2017-11-01

    The focus of this article is to highlight novel inhibitors and current examples where the use of selective small-molecule inhibitors has been critical in defining the roles of matrix metalloproteinases (MMPs) in disease. Selective small-molecule inhibitors are surgical chemical tools that can inhibit the targeted enzyme; they are the method of choice to ascertain the roles of MMPs and complement studies with knockout animals. This strategy can identify targets for therapeutic development as exemplified by the use of selective small-molecule MMP inhibitors in diabetic wound healing, spinal cord injury, stroke, traumatic brain injury, cancer metastasis, and viral infection.

  12. The in vitro and in vivo influence of 4-META/MMA-TBB resin components on dental pulp tissues.

    2001-08-01

    The purpose of this study was to qualitate the penetration of the major components of 4-META/MMA-TBB adhesive resin (4-META resin) and to characterize their influence on the in vitro and in vivo wound healing of dental pulp tissues. Fresh 4-META resin was applied to rabbit mesentery; its components penetrated the mesentery to form three of layers, depending on the amounts of monomer components in the tissue. The superficial layer was a soft-tissue hybrid layer (STHL), the intermediate layer contained small particles of polymerized 4-META resin, while the deepest layer contained unpolymerized monomer components including MMA and butanol, which were detected by gas chromatography (GC). To characterize the in vivo effects of the deepest layer, we immersed the pulp tissue in MMA or in 5% 4-META/MMA and autotransplanted it to placement beneath a rabbit kidney capsule. The MMA-immersed pulp was positive for osteocalcin and presented osteodentin formation at 7 days, as did the untreated control pulp tissue. In contrast, the 5% 4-META/MMA-immersed pulp collapsed into the cell-deficient fibrous connective tissue, with slight calcification by 7 days and less osteodentin formation at 14 days. Analysis of these data suggests that MMA does not inhibit osteogenic activity of pulp tissue, while 5% 4-META/MMA does inhibit osteogenic activity to some extent.

  14. Critical Exponents, Scaling Law, Universality and Renormalization Group Flow in Strong Coupling QED

    Science.gov (United States)

    Kondo, Kei-Ichi

    The critical behavior of strongly coupled QED with a chiral-invariant four-fermion interaction (gauged Nambu-Jona-Lasinio model) is investigated through the unquenched Schwinger-Dyson equation including the fermion loop effect at the one-loop level. It is shown that the critical exponents satisfy the (hyper)scaling relations as in the quenched case. However, the respective critical exponent takes the classical mean-field value, and consequently unquenched QED belongs to the same universality class as the zero-charge model. On the other hand, it is pointed out that quenched QED violates not only universality but also weak universality, due to continuously varying critical exponents. Furthermore, the renormalization group flow of constant renormalized charge is given. All the results are consistent with triviality of QED and the gauged Nambu-Jona-Lasinio model in the unquenched case.

    We use the generalized SU(3) version of the Nambu and Jona-Lasinio model to discuss properties of mesons, constituent quarks and vacuum structure as a function of density and temperature in compressed matter. Systematic low-density expansions are derived. In particular, we show that effects due to finite quasi-particle size are important in stabilizing the density and temperature dependence of the pion mass. (orig.).

The order parameter for Polyakov loops is demonstrated to signal the appearance of a transition for $SU(3)_{c}$ analogous to Gross-Witten (GW-) phase transition instead of the deconfinement phase transition to quark-gluon plasma. The asymptotic restoration of Polyakov loops is conjectured to be a th...

    We discuss shear viscosity of the quark matter by using Kubo formula. The shear viscosity is calculated in the framework of the quasi-particle RPA for the Nambu-Jona-Lasinio model. We obtain a formula that the shear viscosity is expressed by the quadratic form of the quark spectral function in the chiral symmetric phase. The magnitude of the shear viscosity is discussed assuming the Breit-Wigner type for the spectral function.

  8. Emergency Preservation and Resuscitation Trial: A Philosophical Justification for Non-Voluntary Enrollment.

    Science.gov (United States)

    Tigard, Daniel

    2016-06-01

    In a current clinical trial for Emergency Preservation and Resuscitation (EPR), Dr. Samuel Tisherman of the University of Maryland aims to induce therapeutic hypothermia in order to 'buy time' for operating on victims of severe exsanguination. While recent publicity has framed this controversial procedure as 'killing a patient to save his life', the US Army and Acute Care Research appear to support the study on the grounds that such patients already face low chances of survival. Given that enrollment in the trial must be non-voluntary, the study has received an exemption from federal standards for obtaining informed consent. How exactly, if at all, is non-voluntary enrollment morally justifiable? In this essay, I appeal to the notable work of Hans Jonas in an effort to defend the EPR trial's use of non-voluntary enrollment. It is often thought and, as I show, it may appear that Jonas has called for the end of experimental medical practice. Still, I derive from Jonas a principle of double-effect upon which physicians may be seen as morally permitted to pursue innovations in emergency medicine but only as a byproduct of pursuing therapeutic success. With this position, I argue that the EPR trial can be granted a stronger philosophical justification than simply waiving the requirement of obtaining informed consent. The double-effect justification would obtain, perhaps regardless of the success of such innovative procedures as therapeutic hypothermia. © 2015 John Wiley & Sons Ltd.

    Full Text Available Jonas' conception of the principle of responsibility is criticized, because the contemporary techno-sciences are changing societies, not only the biophysical nature. As a good example of techno-science, the new technologies of information and communication (TIC are briefly considered. The Jonasian principle is viewed as an axiological principle, whose imperative formulation is problematical. By distinguishing different subsystems of outstanding values for the techno-sciences, we conclude that there are different notions of responsibility, related to these plurality of types of values.

Foundation problems from the point of view of discourse ethics - This paper discusses the problem of the foundation of the ethics of responsibility in Hans Jonas by the point of view of the Karl-Otto Apel’s discourse ethics. In difference to a unilateral reciprocal ethics – like christians charity, ethics of the bond in the kantian sense, ethics of the face according to Levinas, ethics I-You according to Buber – the approach proposed in this paper can be defined as universal reciprocal. This means that it need to consider the interests of all participants in the “life”.

    Full Text Available Responsibility was always a key theme of Husserl and post-husserlian Phenomenology. This theme is related to Husserl's effort to give an answer, i.e. to offer a solution to the crisis of philosophy and the sciences. The article reconstructs the genesis and the successive development of the concept of responsibility in Husserl's work and its reinterpretation in the post-husserlian phenomenologies, especially those of Martin Heidegger, Jean-Paul Sartre, Hannah Arendt, Jan Patočka, Hans Jonas, Emmanuel Levinas, and Jacques Derrida.

    2006-09-15

    The low energy dynamics of a certain D-brane configuration in string theory is described at weak t'Hooft coupling by a nonlocal version of the Nambu-Jona-Lasinio model. We study this system at finite temperature and strong t'Hooft coupling, using the string theory dual. We show that for sufficiently low temperatures chiral symmetry is broken, while for temperatures larger then the critical value, it gets restored. We compute the latent heat and observe that the phase transition is of the first order.

    Gastineau, F; Blanquier, E; Aichelin, J

    2005-07-29

    The Nambu-Jona-Lasinio Lagrangian offers an explication of the seemingly contradictory observations that (a) the energy loss in the entrance channel of heavy ion reactions is not sufficient to thermalize the system and that (b) the observed hadron cross sections are in almost perfect agreement with hydrodynamical calculations. According to this scenario, a critical opacity develops close to the chiral phase transition which equilibrates and hadronizes the expanding system very effectively. It creates as well radial flow and, if the system is not isotropic, finite upsilon2 values.

    The effects of chiral symmetry breaking are examined for quasi-elastic electron scattering on nuclei. Nucleons are assumed to be composed of constituent quarks with masses that depend on density. This density dependence is determined on the basis of the Nambu-Jona-Lasinio model. It is found that the effects of chiral symmetry breaking are in the right direction and the right order of magnitude to explain the discrepancies between theory and experiment.

    2010-01-01

    Three ethics exist as a condition of possibility of any possible ethics, following a material and biological foundation. This content argument (not logical-formal) supposes a refutation of the naturalistic fallacy that the analytical philosophy attributes to Hume, in three areas of the ethical human experience: body, society and nature. These are: the ethics of the species [J. Habermas], the ethics of liberation [E. Dussel] and the ethics of the responsibility [H. Jonas]. This material argument is a philosophical foundation to considering for three types of applied ethics: medical bioethics, development ethics and environmental ethics.

  3. DSMC study of oxygen shockwaves based on high-fidelity vibrational relaxation and dissociation models

    2017-01-01

    This work evaluates high-fidelity vibrational-translational (VT) energy relaxation and dissociation models for pure O2 normal shockwave simulations with the direct simulation Monte Carlo (DSMC) method. The O2-O collisions are described using ab initio state-specific relaxation and dissociation models. The Macheret-Fridman (MF) dissociation model is adapted to the DSMC framework by modifying the standard implementation of the total collision energy (TCE) model. The O2-O2 dissociation is modeled with this TCE+MF approach, which is calibrated with O2-O ab initio data and experimental equilibrium dissociation rates. The O2-O2 vibrational relaxation is modeled via the Larsen-Borgnakke model, calibrated to experimental VT rates. All the present results are compared to experimental data and previous calculations available in the literature. It is found that, in general, the ab initio dissociation model is better than the TCE model at matching the shock experiments. Therefore, when available, efficient ab initio models are preferred over phenomenological models. We also show that the proposed TCE + MF formulation can be used to improve the standard TCE model results when ab initio data are not available or limited.

    1999-01-01

    Full Text Available Three kinds of results have been described in this paper. Firstly, an experimental study of the Rossby vortex meridional drift on the rotating shallow water has been carried out. Owing to the stringent physical analogy between the Rossby vortices and drift vortices in the magnetized plasma, the results obtained have allowed one to make a conclusion that the transport rate of the plasma, trapped by the drift vortices, across the magnetic field is equivalent to the “gyro-Bohm” diffusion coefficient. Secondly, a model of big vortices of the type of the Great Red Spot of Jupiter, dominating in the atmospheres of the outer planets, has been produced. Thirdly, the rotating shallow water modeling has been carried out of the hydrodynamical generation mechanism of spiral structures in galaxies. Trailing spiral waves of various azimuthal modes, generated by a shear flow between fast rotating “nucleus” and slow rotating periphery, were produced. The spirals are similar to those existing in the real galaxies. The hydrodynamical concept of the spiral structure formation in galaxies has been substantiated. Strong anticyclonic vortices between the spiral arms of the structures under study have been discovered for the first time. The existence of analogous vortices in real galaxies has been predicted. (This prediction has been reliably confirmed recently in special astronomical observations, carried out on the basis of the mentioned laboratory modeling and the prediction made – see the paper by A. Fridman et al. (Astrophysics and Space Science, 1997, 252, 115.

    When it comes to food marketing, children are one of the major targets. Regulatory actions can play a strategic role in health protection. The objective of this research was to characterize the ethical perspective in the discourse against state regulatory actions on food marketing directed at children, aiming to understand the context of the discourse's production and how it creates meaning. The methodology adopted was qualitative, with documentary analysis and use of concepts and procedures from Discourse Analysis. The work of Hans Jonas, specifically his Responsibility Principle, and Garrafa and Port's Intervention Bioethics oriented the analysis. The self-regulation discourse analysis showed an ethical perspective in which relations of consumption predominate over the children´s vulnerability. The rhetorical excess is constant, as well as the use of resources like naturalization, untruthfulness, ideological dissimulation and euphemism. An erasure of social conflicts takes place, and an ahistorical perspective is present. The discourse does not align with Jonas´ Responsibility Principle, nor those of Intervention Bioethics. Lastly, the ethical perspective of the discourse represents a double paradox, because it is a business discourse that hides its competitive roots and metamorphoses into an ethical one.

    Full Text Available In this article, several issues are discussed and related, namely, the phonograph recordings that have recently started being released with Lithuanian folk music from the first half of the 20th century; the folk melodies of the South Eastern Lithuania and the impact from the melodies of the eastern neighbors observed; the formation of professional Lithuanian music, a considerable part of which comprised harmonized folksongs in the beginning of the 20th century. According to the author, the first sound documents were recorded at the turning point, when the centuries-long formation of the Lithuanian folk music dialects was over and the decline of the regional differences started. However, folk music dialects did not vanish without the trace, but were integrated into the professional music culture instead. The change of the Lithuanian music culture in the first half of the 20th century was not a spontaneous process, as the ethnologists and composers began influencing the continuation or break in the traditions. The article is based on the sound recordings, collections of the folk music, the ethno-musicological research, and the written heritage of Eduard Wolter, Aukusti Robert Niemi, Jonas Basanavičius, Mikalojus Konstantinas Čiurlionis, Jonas Balys and Zenonas Slaviūnas.

    Full Text Available Lois Lowry (1937- is a prolific author having a number of books – Number the Stars (1989, Gathering Blue (2000, and Messenger (2004 – and awards especially in the field of children’s literature. Her significant science fiction novel, The Giver (1993, presents a social panorama in order to thoroughly analyze the society’s mechanical life style. As an example of dystopia, the author delineates a systematically organized social order where people abide by the rules naturally. Nevertheless, Jonas, the protagonist and Receiver of Memory, is the first person to discern robotic/mechanical order in the society which is transformed into “sameness” eliminating all individual differences and emotions such as pain, happiness, cold, colors, and so on. Therefore, Receiver of Memory storing past memories of the society is the only one who is aware of human characteristics. The crucial point is that human figure, far from the current one, displays inhuman (non-human features without memories and hope. Mechanical association between individuals and social structure ascertains artificial form of life in which there is no chance to choose. After learning truths behind the strict order, Jonas is in pursuit of real world with all kinds of feelings; however, his recognition is not able to change the whole society. Hence, this paper aims at delving into the relationship between human nature and society with regard to posthuman approach and inhuman human form in accordance with transformation of human nature.

    Full Text Available Este artículo intenta caracterizar la especificidad de los problemas morales en salud pública y analizar la aplicabilidad del modelo principialista como padrón para dirimir sus conflictos. Aunque considerado pertinente para la bioética clínica, este modelo no es aplicable sin más a los dilemas en salud pública, puesto que se fundamenta en la moral de las interrelaciones médico-paciente. Se analiza la pertinencia de los principios de "solidaridad", de "responsabilidad óntica" según Jonas, y de "responsabilidad diacónica" según Lévinas, destacando la inaplicabilidad del primero y la posible adaptación de los otros dos a la salud pública. A ese respecto se discute la posibilidad de vincular la preocupación ontológica de Jonas y la trascendental de Lévinas, proponiendo un principio de protección que sería más adecuado a los propósitos de una ética de la salud pública, permitiendo identificar claramente los objetivos y los actores implicados en una implementación de políticas públicas moralmente correctas y pragmáticamente efectivas.

  10. Holograms of a dynamical top quark

    Clemens, Will; Evans, Nick; Scott, Marc

    2017-09-01

    We present holographic descriptions of dynamical electroweak symmetry breaking models that incorporate the top mass generation mechanism. The models allow computation of the spectrum in the presence of large anomalous dimensions due to walking and strong Nambu-Jona-Lasinio interactions. Technicolor and QCD dynamics are described by the bottom-up Dynamic AdS/QCD model for arbitrary gauge groups and numbers of quark flavors. An assumption about the running of the anomalous dimension of the quark bilinear operator is input, and the model then predicts the spectrum and decay constants for the mesons. We add Nambu-Jona-Lasinio interactions responsible for flavor physics from extended technicolor, top-color, etc., using Witten's multitrace prescription. We show the key behaviors of a top condensation model can be reproduced. We study generation of the top mass in (walking) one doublet and one family technicolor models and with strong extended technicolor interactions. The models clearly reveal the tensions between the large top mass and precision data for δ ρ . The necessary tunings needed to generate a model compatible with precision constraints are simply demonstrated.

  11. Fierz-complete NJL model study: Fixed points and phase structure at finite temperature and density

    Braun, Jens; Leonhardt, Marc; Pospiech, Martin

    2017-10-01

    Nambu-Jona-Lasinio-type models are frequently employed as low-energy models in various research fields. With respect to the theory of the strong interaction, this class of models is indeed often used to analyze the structure of the phase diagram at finite temperature and quark chemical potential. The predictions from such models for the phase structure at finite quark chemical potential are of particular interest as this regime is difficult to access with lattice Monte Carlo approaches. In this work, we consider a Fierz-complete version of a Nambu-Jona-Lasinio model. By studying its renormalization group flow, we analyze in detail how Fierz-incomplete approximations affect the predictive power of such model studies. In particular, we investigate the curvature of the phase boundary at small chemical potential, the critical value of the chemical potential above which no spontaneous symmetry breaking occurs, and the possible interpretation of the underlying dynamics in terms of difermion-type degrees of freedom. We find that the inclusion of four-fermion channels other than the conventional scalar-pseudoscalar channel is not only important at large chemical potential but also leaves a significant imprint on the dynamics at small chemical potential as measured by the curvature of the finite-temperature phase boundary.

  12. Baryons and baryonic matter in four-fermion interaction models

    Energy Technology Data Exchange (ETDEWEB)

    Urlichs, K.

    2007-02-23

    In this work we discuss baryons and baryonic matter in simple four-fermion interaction theories, the Gross-Neveu model and the Nambu-Jona-Lasinio model in 1+1 and 2+1 space-time dimensions. These models are designed as toy models for dynamical symmetry breaking in strong interaction physics. Pointlike interactions (''four-fermion'' interactions) between quarks replace the full gluon mediated interaction of quantum chromodynamics. We consider the limit of a large number of fermion flavors, where a mean field approach becomes exact. This method is formulated in the language of relativistic many particle theory and is equivalent to the Hartree-Fock approximation. In 1+1 dimensions, we generalize known results on the ground state to the case where chiral symmetry is broken explicitly by a bare mass term. For the Gross-Neveu model, we derive an exact self-consistent solution for the finite density ground state, consisting of a one-dimensional array of equally spaced potential wells, a baryon crystal. For the Nambu- Jona-Lasinio model we apply the derivative expansion technique to calculate the total energy in powers of derivatives of the mean field. In a picture akin to the Skyrme model of nuclear physics, the baryon emerges as a topological soliton. The solution for both the single baryon and dense baryonic matter is given in a systematic expansion in powers of the pion mass. The solution of the Hartree-Fock problem is more complicated in 2+1 dimensions. In the massless Gross-Neveu model we derive an exact self-consistent solution by extending the baryon crystal of the 1+1 dimensional model, maintaining translational invariance in one spatial direction. This one-dimensional configuration is energetically degenerate to the translationally invariant solution, a hint in favor of a possible translational symmetry breakdown by more general geometrical structures. In the Nambu-Jona-Lasinio model, topological soliton configurations induce a finite baryon

    Full Text Available Por mais que o avanço da ciência e da tecnologia esteja na raiz de vitórias decisivas na luta por melhores condições sociais, é impossível não reconhecer a ameaça crescente que o conhecimento e suas aplicações práticas representam não só para as sociedades humanas, mas para a vida em seu conjunto. A capacidade humana de intervir sobre a natureza é hoje muito maior que a possibilidade de prever com um mínimo de segurança os resultados dessa intervenção. Para Hans Jonas esse contraste só pode ser abordado com base numa exigência ética que ele sintetiza no Princípio Responsabilidade, e que se apoia na heurística do medo. Baseado numa abordagem crítica do dualismo que marca a cultura ocidental e separa matéria e espírito, corpo e mente, natureza e sociedade, Hans Jonas rejeita a ideia de que uma organização social voltada explicitamente à satisfação das necessidades humanas (e não ao lucro suprima a exigência de uma reflexão específica sobre as ameaças vindas da expansão autônoma da ciência e da tecnologia. Este trabalho, além de expor as bases do dualismo estudado por Jonas, procura mostrar que suas preocupações não são contempladas pela eventual adoção do princípio da precaução e mostra, ao final, duas áreas (biologia e geoengenharia em que a aplicação de sua filosofia da tecnologia pode ser especialmente relevante.

Measures included Raven's Standard Progressive Matrices (1959), a systematic observation checklist for cognitive behaviors (Martin & Craft, 1998), and critical and creative problem situations to which students had to respond. Results were compared with those from a study of similar learners in the United States (Martin & Jonas, 1985), and little difference was found. Students in all three countries improved in reasoning, devising real-world problem solutions involving critical thinking (but not creative thinking), using cognitive vocabulary in the classroom, and expressing others' viewpoints. Postintervention focus groups showed teachers in China used a more invariant sequence in teaching the cognitive strategies, but teachers in all three countries experienced similar expansion in cognitive terminology and self-perceptions as teachers of problem solving.

  18. A SURFACE CRYSTALLOGRAPHY STUDY BY DYNAMICAL LEED OF THE (sqrt3xsqrt3)R30o CO STRUCTURE ON THE Rh(111) CRYSTAL SURFACE

    The atomic positions of the Rh(111) + ({radical}3 x {radical}3)R30{sup o} CO and CO{sub 2} surfaces are analyzed by dynamical LEED. The Rh(111) + ({radical}3 x {radical}3)R30{sup o} CO and CO{sub 2} systems produce identical I-V curves, confirming the dissociation of CO{sub 2} to CO on this surface. The adsorbed CO is found to stand perpendicular to the surface with the carbon end down at an atop site (that is, terminally bonded). The CO overlayer spacings are d{sub RhC} = 1.95 {+-} 0.1 {angstrom} and d{sub CD} = 1.07 {+-} 0.1 {angstrom}. This geometry yields a Zanazzi-Jona R-factor of 0.40 and a Pendry R-factor of 0.50.

    Full Text Available In this issue, there is a focus on the usability of new digital technology and media in formal and non-formal learning settings. Three different articles and one interview address this theme from the perspective of design. However, the notion of design is being explored from two somewhat different positions. Øystein Gilje and Marie Leijon use it as an analytical concept in the articles, as it highlights the creative aspects of learning and communication. In an article by Majgaard, Misfeldt and Nielsen and in an interview with professor Jonas Löwgren, it refers instead to a creative process of developing specific tools that, for instance, can be used to support communicating and learning. Both these approaches contribute to an understanding of collaborative and learning processes.

    The properties of magnetized color superconducting cold dense quark matter under compact star conditions are investigated using an S U (2 )f Nambu Jona-Lasinio (NJL)-type model in which the divergences are treated using a magnetic field independent regularization scheme in order to avoid unphysical oscillations. We study the phase diagram for several model parametrizations. The features of each phase are analyzed through the behavior of the chiral and superconducting condensates together with the different particle densities for increasing chemical potential or magnetic field. While confirming previous results derived for the zero magnetic field or isospin symmetric matter case, we show how the phases are modified in the presence of β -equilibrium as well as color and electric charge neutrality conditions.

    2006-01-01

    Using ideas gleaned from the philosophy of technology of Martin Heidegger and Hans Jonas and the philosophy of health of Georges Canguilhem, I argue that one of the characteristics of emerging medical technologies is that these technologies lead to new conceptions of health. When technologies enable the body to respond to more and more challenges of disease, we thus establish new norms of health. Given the continued development of successful technologies, we come to expect more and more that our bodies should be able to respond to ever-new challenges of environment and disease by establishing ever-new norms of health. Technologies may aim at the prevention and treatment of disease, but they also bring about modifications of what we consider normal for the human being. Thus, new norms of health arise from technological innovation.

  11. Views on Biotic Nature and the Idea of Sustainable Development

    Science.gov (United States)

    Łepko, Zbigniew

    2017-12-01

    The search for balance between humankind's civilisational aspirations and the durable protection of nature is conditioned by contemporaneous views of biotic nature. Of particular importance in this regard are physiocentric and physiological views that may be set against one another. The first of these was presented by Hans Jonas, the second by Lothar Schäfer. This paper does not confine itself to setting one view against the other, but rather sets minimum conditions for cooperation between their promoters in the interests of balance between the aspirations of the present generation and those of future generations. Both views of nature are in their own way conducive to a break with the illusion present in some areas of the modern natural sciences - that nature is a boundless area of are inexhaustible resources.

    The 200th birthday of John Lamont (1805-1879, Figure 1), a pioneer in the study of geomagnetism, was marked on 13 December 2005. Lamont founded the Munich Geomagnetic Observatory in 1840 and was a member of the group of scientists including Carl Friedrich Gauss, Alexander von Humboldt, Eduard Sabine, Jonas Angstrøm, Humphret Lloyd, Adolf Kupffer, Karl Kreil, and Adolphe Quetelet who composed the Göttingen Magnetic Union. They organized an international network of geomagnetic observatories [Barraclough et al., 1992]. The present knowledge of the geomagnetic field and its secular variation is largely based on the data collected by the global network of geomagnetic observatories during the last 170 years. Lamont's talents and his dedication and enthusiasm for discovery are reflected in the depth and scope of his contributions to a broad variety of natural sciences such as astronomy, meteorology, geomagnetism, and geodesy. However, this article just touches on his merits in geomagnetism.

  13. After Fukushima: The precautionary principle revisited

    Wolfgang Huber

    2012-12-01

    Full Text Available Etienne de Villiers, more than other theologians, elaborates on basic elements of a Christian ethics of responsibility. He distinguishes between retrospective and prospective responsibility. The prospective aspect attracted awareness after the nuclear accident in the Fukushima reactors on 11 March 2011. The question on how to respond in an ethically responsible manner to catastrophic risks was put back on the agenda. The article takes up this question and discusses the answer given in the international debate by the introduction of the �precautionary principle�. The principle is described with its background in the �heuristics of fear�, proposed by the philosopher Hans Jonas. Four criticisms are discussed in detail relating to the problems of scientific uncertainty, the burden of proof, the weight of damages and the perils of precaution. That leads to a reformulation of the precautionary principle as a concrete element within an ethics of responsibility.

  15. Non-perturbative effective interactions in the standard model

    Arbuzov, Boris A

    2014-01-01

    This monograph is devoted to the nonperturbative dynamics in the Standard Model (SM), the basic theory of all, but gravity, fundamental interactions in nature. The Standard Model is devided into two parts: the Quantum chromodynamics (QCD) and the Electro-weak theory (EWT) are well-defined renormalizable theories in which the perturbation theory is valid. However, for the adequate description of the real physics nonperturbative effects are inevitable. This book describes how these nonperturbative effects may be obtained in the framework of spontaneous generation of effective interactions. The well-known example of such effective interaction is provided by the famous Nambu--Jona-Lasinio effective interaction. Also a spontaneous generation of this interaction in the framework of QCD is described and applied to the method for other effective interactions in QCD and EWT. The method is based on N.N. Bogoliubov conception of compensation equations. As a result we then describe the principle feathures of the Standard...

    We present a study of the dressed quark mass function and the pion structure in Minkowski space using the Covariant Spectator Theory (CST). The quark propagators are dressed with the same kernel that describes the interaction between different quarks. We use an interaction kernel in momentum space that is a relativistic generalization of the linear confining q-qbar potential and a constant potential shift that defines the energy scale. The confining interaction has a Lorentz scalar part that is not chirally invariant by itself but decouples from the equations in the chiral limit and therefore allows the Nambu--Jona-Lasinio (NJL) mechanism to work. We adjust the parameters of our quark mass function calculated in Minkowski-space to agree with LQCD data obtained in Euclidean space. Results of a calculation of the pion electromagnetic form factor in the relativistic impulse approximation using the same mass function are presented and compared with experimental data.

    Jonas Schneider tackles a question that is of great interest both to scholars of nuclear proliferation and to practitioners of nonproliferation diplomacy: Why do some political leaders of U.S. allies agree to abandon their nation's nuclear weapons activities, while others - who are often members of the same allied government and sometimes even of the same political party - steadfastly reject such a course reversal? Our existing stock of theories does not fare well in accounting for this important variation in leaders' attitudes. To solve this puzzle, Schneider develops an innovative theory that draws on the individual status conceptions of allied political leaders. Subsequently, the author undertakes to test his theory using four thoroughly researched case studies, and he derives important lessons for international nonproliferation diplomacy toward the Middle East and Northeast Asia.

    In high density quark matter under a strong external magnetic field, possible phases are investigated by using the two-flavor Nambu-Jona-Lasinio (NJL) model with tensor-type four-point interaction between quarks, as well as the axial-vector-type four-point interaction. In the tensor......-type interaction under the strong external magnetic field, it is shown that a quark spin polarized phase is realized in all regions of the quark chemical potential under consideration within the lowest Landau level approximation. In the axial-vector-type interaction, it is also shown that the quark spin polarized...... phase appears in the wide range of the quark chemical potential. In both the interactions, the quark mass in zero and small chemical potential regions increases which indicates that the chiral symmetry breaking is enhanced, namely the magnetic catalysis occurs....

  2. Multiple critical endpoints in magnetized three flavor quark matter

    2018-01-01

    The magnetized phase diagram for three-flavor quark matter is studied within the Polyakov extended Nambu-Jona-Lasinio model. The order parameters are analyzed with special emphasis on the strange quark condensate. We show that the presence of an external magnetic field induces several critical endpoints (CEPs) in the strange sector, which arise due to the multiple phase transitions that the strange quark undergoes. The spinodal and binodal regions of the phase transitions are shown to increase with external magnetic field strength. The influence of strong magnetic fields on the isentropic trajectories around the several CEPs is analyzed. A focusing effect is observed on the region towards the CEPs that are related with the strange quark phase transitions. Compared to the chiral transitions, the deconfinement transition turns out to be less sensitive to the external magnetic field and the crossover nature is preserved over the whole phase diagram.

  5. The NJL Model for Quark Fragmentation Functions

    2009-10-01

    A description of fragmentation functions which satisfy the momentum and isospin sum rules is presented in an effective quark theory. Concentrating on the pion fragmentation function, we first explain the reason why the elementary (lowest order) fragmentation process q → qπ is completely inadequate to describe the empirical data, although the “crossed” process π → qq describes the quark distribution functions in the pion reasonably well. Then, taking into account cascade-like processes in a modified jet-model approach, we show that the momentum and isospin sum rules can be satisfied naturally without introducing any ad-hoc parameters. We present numerical results for the Nambu-Jona-Lasinio model in the invariant mass regularization scheme, and compare the results with the empirical parametrizations. We argue that this NJL-jet model provides a very useful framework to calculate the fragmentation functions in an effective chiral quark theory.

The validity of the mechanisms of the “Greed and Grievance” model, alongside leadership and external interventions are tested in four periods of initiation and intensification of the conflict in Angola. All mechanisms are present but their relative relevance varies throughout the conflict. Among the mechanisms identified in each period the most relevant in the Cold War period are the international and regional interventions in 1961 and 1975 and in the post-Cold War period, the “greed” factors in 1992 (oil and diamonds, poverty and war capital and the UNITA leadership of Jonas Savimbi in 1998. The case study provides evidence that “greed” and “grievance” can be interlinked (such as in 1992 and confirms the relevance of leadership and external interventions mechanisms.

    Acute poisonings with corrosive substances may cause serious chemical injuries to upper gastrointestinal tract, the most common location being the esophagus and the stomach. If the patient survives the acute phase of the poisoning, regenerative response may result in esophageal and/or gastric stenosis and increased risk for esophageal cancer. Acute corrosive intoxications pose a major problem in clinical toxicology since the most commonly affected population are the young with psychic disorders, suicidal intent and alcohol addiction. In establishing the diagnosis of acute corrosive poisonings, the severity of the post-corrosive endoscopic changes of the esophagus, stomach and duodenum is of major importance. According to Holinder and Fridman classification, post-corrosive endoscopic changes are classified in three degrees: First degree--superficial damage associated with hyperthermia, epithelial desquamation and mucous edema. Second degree--transmucous damage affecting all of the mucosal layers, followed by exudation, erosions and ulcerations. Third degree--transmural damage associated with ulcer's penetration in the deep layers of the tissue and neighboring organs. Severity of the lesions depends on the nature, quantity and concentration of the corrosive substance, the duration of exposure and current state of the exposed organs. Most often caustic injuries occur to the esophagus and stomach since the corrosive substance remains there for a longer period of time. Treatment of the acute corrosive intoxications include: neutralization of corrosive agents, antibiotics, corticosteroids, anti-secretory therapy, nutritional support, collagen synthesis inhibitors, esophageal dilation and stent placement, and surgery. The most common complications that may appear are: perforation, gastrointestinal bleeding, sepsis, esophageal strictures and stenosis, stenosis of gastric antrum and pylorus, cancer of the esophagus and the stomach.

  11. Is the snow of yesterday, the flood of tomorrow?

    "The snow of yesterday, is the flood of tomorrow." This famous quote could just as much be a folk wisdom or a farmer's wisdom, but it describes the social awareness that the water of the winterly snow amounts may lead to flooding in the spring. Furthermore, this common experience finds its confirmation in reality - though only at a first glance. For example, in spring 1999, a major flooding occurred after a winter with the highest snow amounts recorded over the last 30 years. This is to forget that sustained rainfall occurred prior to the flood event. For scientists, the question remains whether and to what extent winterly snow contributes to spring flooding and how this information might help in forecasts. As snow depth measurements are insufficiently for an empirical study, we set up a hydrological model approach, combining the various snow conditions with the different spring weather conditions of the last 29 years (1981-2009). The study was conducted in three mesoscale (380-550 km2) headwater catchments in the Bernese Oberland. We set up the hydrological model WaSiM-ETH and validated the model against runoff and snow water equivalent. Then, we estimated the start of the melting season for each year following the approach of Egli and Jonas (2009). This date and the according SWE serves as the initial condition to model the spring runoff using all weather conditions during the last 29 years (until June). This leads to 841 possible spring runoff series. Assuming that the last 29 years represent a major part of the natural variance, the influence of snow on the spring discharge and the flood peak in specific is presented. We found that the snow amount and the flood peak are not directly correlated as suggested by the saying. But, the snow amount causes primarily higher mean flow values while the effect on spring flood peaks are a function of weather. Thereby, snow conditions primarily alter the disposition of the catchments to a flood event. We estimate the

  13. Short-range correlations in quark and nuclear matter

    2007-06-15

    In the first part of this thesis, the role of short-range correlations in quark matter is explored within the framework of the Nambu-Jona-Lasinio model. Starting from a next-to-leading order expansion in the inverse number of the quark colors, a fully self-consistent model constructed that employs the close relations between spectral functions and self-energies. In contrast to the usual quasiparticle approximations, this approach allows the investigation of the collisional broadening of the quark spectral function. Numerical calculations at various chemical potentials and zero temperature show that the short-range correlations do not only induce a finite width of the spectral function but also have some influence on the structure of the chiral phase transition. In the second part of this thesis, the temperature and density dependence of the nucleon spectral function in symmetric nuclear matter is investigated. The short-range correlations can be well described by a simple, self-consistent model on the one-particle-two-hole and two-particle-one-hole level (1p2h, 2p1h). The thermodynamically consistent description of the mean-field properties of the nucleons is ensured by incorporating a Skyrme-type potential. Calculations at temperatures and densities that can also be found in heavy-ion collisions or supernova explosions and the formation of neutron stars show that the correlations saturate at high temperatures and densities.

    I.M. Pei's Mesa Laboratory for the National Center for Atmospheric Research in Boulder, Colorado, and Louis Kahn's Salk Institute in La Jolla, California, are rare examples of laboratories as celebrated for their architecture as for their scientific contributions. Completed in the mid-1960s, these signature buildings still express the scientific style of their founding directors, Walter Roberts and Jonas Salk. yet in commissioning their laboratories, Roberts and Salk had to work with architects as strong-willed as themselves. A close reading of the two laboratories reveals the ongoing negotiations and tensions in collaborations between visionary scientist and visionary architect. Moreover, Roberts and Salk also had to become architects of atmospheric and biomedical sciences. For laboratory architecture, however flexible in theory, necessarily stabilizes scientific practice, since a philosophy of research is embedded in the very structure of the building and persists far longer than the initial vision and mission that gave it life. Roberts and Salk's experiences suggest that even the most carefully designed laboratories must successfully adapt to new disciplinary configurations, funding opportunities, and research priorities, or risk becoming mere architectural icons.

  15. Dual use and the ethical responsibility of scientists.

    Ehni, Hans-Jörg

    2008-01-01

    The main normative problem in the context of dual use is to determine the ethical responsibility of scientists especially in the case of unintended, harmful, and criminal dual use of new technological applications of scientific results. This article starts from an analysis of the concepts of responsibility and complicity, examining alternative options regarding the responsibility of scientists. Within the context of the basic conflict between the freedom of science and the duty to avoid causing harm, two positions are discussed: moral skepticism and the ethics of responsibility by Hans Jonas. According to these reflections, four duties are suggested and evaluated: stopping research, systematically carrying out research for dual-use applications, informing public authorities, and not publishing results. In the conclusion it is argued that these duties should be considered as imperfect duties in a Kantian sense and that the individual scientist should be discharged as much as possible from obligations which follow from them by the scientific community and institutions created for this purpose.

Furthermore, the chemistry of microporous hydroxyapatite and zirconia were tested to determine which of these two ceramics are most suitable for guided bone generation. 24 hollow domes in two different ceramic materials were placed subperiosteal on rabbit skull bone. The rabbits were sacrificed after 12 weeks and the histology results were analyzed regarding bone-to-material contact and volume of newly formed bone. The results suggest that the effect of the microporous structure of hydroxyapatite seems to facilitate for the bone cells to adhere to the material and that zirconia enhance a slightly larger volume of newly formed bone. In conclusion, the results of the current study demonstrated that ceramic space maintaining devices permits new bone formation and osteoconduction within the dome.

    The American Academy of Psychiatry and the Law (AAPL) was organized in 1969, in large part through the efforts of Dr. Jonas Rappeport. The founders of AAPL emphasized that an important purpose of the organization was to advance knowledge in the area of psychiatry and the law. The science of forensic psychiatry has since been vigorously debated. In 2005, Congress enacted a statute authorizing the National Academy of Sciences (NAS) to conduct a study on the state of the forensic sciences in the United States. As a result of this legislation, a forensic science committee was formed, and the report, "Strengthening Forensic Science in the United States: A Path Forward," was produced, emphasizing the need for research in the forensic disciplines, particularly those that rely on more subjective assessments. The committee also identified two important factors relevant to standards of evidence admissibility: the scientific methodology used and the impact of bias on the interpretation of data. In this article, I apply the NAS committee's findings to the field of forensic psychiatry, with specific recommendations to assist educators in achieving more objective assessment methodologies, critical in forensic education and the search for truth.

  18. Development of a Model for Dynamic Recrystallization Consistent with the Second Derivative Criterion

    Full Text Available Dynamic recrystallization (DRX processes are widely used in industrial hot working operations, not only to keep the forming forces low but also to control the microstructure and final properties of the workpiece. According to the second derivative criterion (SDC by Poliak and Jonas, the onset of DRX can be detected from an inflection point in the strain-hardening rate as a function of flow stress. Various models are available that can predict the evolution of flow stress from incipient plastic flow up to steady-state deformation in the presence of DRX. Some of these models have been implemented into finite element codes and are widely used for the design of metal forming processes, but their consistency with the SDC has not been investigated. This work identifies three sources of inconsistencies that models for DRX may exhibit. For a consistent modeling of the DRX kinetics, a new strain-hardening model for the hardening stages III to IV is proposed and combined with consistent recrystallization kinetics. The model is devised in the Kocks-Mecking space based on characteristic transition in the strain-hardening rate. A linear variation of the transition and inflection points is observed for alloy 800H at all tested temperatures and strain rates. The comparison of experimental and model results shows that the model is able to follow the course of the strain-hardening rate very precisely, such that highly accurate flow stress predictions are obtained.

    The aim of this study was to review the current situation of penile prosthesis in the treatment of erectile dysfunction and to analyze the indications, degree of acceptability and complications in our experience. From 1984 to 2003, 48 implants were inserted in men suffering from impotence due to different etiologies. The mean age was 55 years. Vascular disease, Diabetes and pelvic surgery were the most common pathologies recorded. The type of prothesis inserted were malleable inactive in 7 cases (14.58%), Jonas6, Acu-form1. Inflable active with 3 components in 19 cases (39.58%), AMS 700 plus17, Alpha2. Inflable active integrated in 5 cases (10.41%) Hydroflex4, Dynaflex1. Inflable active with 2 components in 17 cases (35.4%), Ambicor2, Mark II15. Infection of the prosthesis was observed in 6.25% of the cases. This infectious complication required removal of the prosthesis. 4.16% of the cases complained of mechanical failure that required change of the prosthesis. 80% of the patients were satisfied with the results. Penile prostheses continue to be an effective and valid therapeutic alternative in impotent. Although the complication rate is low, adequate information must be provided to the patient.

  1. The dual quark condensate in local and nonlocal NJL models: An order parameter for deconfinement?

    Directory of Open Access Journals (Sweden)

    Federico Marquez

    2015-07-01

    Full Text Available We study the behavior of the dual quark condensate Σ1 in the Nambu–Jona-Lasinio (NJL model and its nonlocal variant. In quantum chromodynamics Σ1 can be related to the breaking of the center symmetry and is therefore an (approximate order parameter of confinement. The deconfinement transition is then signaled by a strong rise of Σ1 as a function of temperature. However, a similar behavior is also seen in the NJL model, which is known to have no confinement. Indeed, it was shown that in this model the rise of Σ1 is triggered by the chiral phase transition. In order to shed more light on this issue, we calculate Σ1 for several variants of the NJL model, some of which have been suggested to be confining. Switching between “confining” and “non-confining” models and parametrizations we find no qualitative difference in the behavior of Σ1, namely, it always rises in the region of the chiral phase transition. We conclude that without having established a relation to the center symmetry in a given model, Σ1 should not blindly be regarded as an order parameter of confinement.

  2. Personal glimpses into the evolution of truncus arteriosus repair.

    2015-04-01

    Truncus arteriosus (common arterial trunk) is an uncommon but complex congenital heart anomaly. Until the early 1970s, typically, patients died between the age of a few weeks to six months. Congestive heart failure owing to large pulmonary blood flow and truncal valve regurgitation was the major cause of death until innovative surgical techniques were discovered. In 1963, Herbert Sloan at the University of Michigan completed the first repair using a nonvalved conduit with long-term survival (not reported until 1974). At the Mayo Clinic, Rastelli and McGoon studied and completed the first repair with a valved homograft in 1967. In 1976, Ebert used the 12-mm Hancock valved conduit in infants under six months of age (University of California, San Francisco). In Boston (mid-1980s), Jonas and Castañeda used aortic homografts, which greatly reduced bleeding as a postoperative complication. In the early 1990s, Bove (University of Michigan) reported outstanding results with an approach based on primary repair within the first few days of life for patients with truncus arteriosus. Improved prognosis for patients with truncus arteriosus resulted from these corrective operations by analyzing the natural history of this condition while applying innovative ideas, improved technology, and perioperative care. © The Author(s) 2015.

The article concludes by bringing these debates to bear on cultural cross-referencing in comparative examples of American texts ( Gattaca [1997] , The Island [2005] , to name two, which tend to imbue frightening aspects of reproductive technologies with signifiers of Nazism, while the German texts tend to implicate America as the future source of nightmarish reproductive possibilities.

    Synthetic biology is regarded as one of the key technosciences of the future. The goal of this paper is to present some fundamental considerations to enable procedures of a technology assessment (TA) of synthetic biology. To accomplish such an early "upstream" assessment of a not yet fully developed technology, a special type of TA will be considered: Prospective TA (ProTA). At the center of ProTA are the analysis and the framing of "synthetic biology," including a characterization and assessment of the technological core. The thesis is that if there is any differentia specifica giving substance to the umbrella term "synthetic biology," it is the idea of harnessing self-organization for engineering purposes. To underline that we are likely experiencing an epochal break in the ontology of technoscientific systems, this new type of technology is called "late-modern technology." -I start this paper by analyzing the three most common visions of synthetic biology. Then I argue that one particular vision deserves more attention because it underlies the others: the vision of self-organization. I discuss the inherent limits of this new type of late-modern technology in the attempt to control and monitor possible risk issues. I refer to Hans Jonas' ethics and his early anticipation of the risks of a novel type of technology. I end by drawing conclusions for the approach of ProTA towards an early societal shaping of synthetic biology.

We find that the {eta}-meson mass, the {eta} {yields} {gamma}{gamma}, {eta} {yields} {gamma}{mu}{sup -}{mu}{sup +} and {eta} {yields} {pi}{sup 0}{gamma}{gamma} decay widths are in good agreement with the experimental values when the U{sub A}(1) breaking is strong and the flavor SU(3) singlet-octet mixing angle {theta} is about zero. The calculated {eta}{gamma}{gamma}{sup *} transition form factor has somewhat weaker dependence on the squared four-momentum of the virtual photon. The effects of the U{sub A}(1) anomaly on the scalar quark contents in the nucleon, the {Sigma}{sub {pi}N} and {Sigma}{sub KN} terms and the baryon number one and two systems are also studied.

    Full Text Available The Swedish author and visionary Carl Jonas Love Almqvist (1793–1866 was the principal for twelve years (1829–1841 of the government-initiated pilot school ”Nya Elementarskolan” (New Elementary School in Stockholm. In this position, he argued that both the school and the state should be built on the same basic idea: the right of individual freedom. This argument is often referred to as ”personlighetsprincipen” (the principle of personality, a concept launched by another prominent figure of the liberal culture of the time, Erik Gustaf Geijer (1783–1847. This article explores how the principle of personality is expressed in the texts of Almqvist and is mainly built upon the concept’s allegorical resources. It examines the thesis that Almqvist’s use of the term is best understood if one distinguishes between the political, pedagogical, and existential dimension of the concept. The article ends with some thoughts about the context of the concept and a discussion on whether Almqvist had a greater interest in personalities than in principles.

    Espen D. Stabell

    2014-11-01

    Full Text Available In this paper I investigate the concept of responsibility in the context of technological innovation, with reference to two types of responsibility: ex post and ex ante responsibility. Exposing the shortcomings of ex post responsibility in the context of innovation, I examine different ways of conceiving of a form of ex ante responsibility suitable for our current technological situation. Here I identify two positions with very different approaches to the question of the ethical status of responsibility: Hans Jonas’s concept of responsibility as an ethical principle structuring moral behavior, and René von Schomberg’s idea of responsibility as “responsiveness” linked to procedures of communication and collaboration. Rejecting von Schomberg’s concept on ethico-philosophical grounds, I argue in favor of a critical rehabilitation of some basic thoughts in the philosophy of Jonas. Finally, I suggest taking the step from the Jonasian ethics of responsibility towards the Hegelian concept of Sittlichkeit – a concrete social morality that disentangles responsibility from the dilemmas of subjectivist morality.

  10. How can video supported reflection enhance teachers' professional development?

    McCullagh, John F.

    2012-03-01

    This paper responds to Eva Lundqvist, Jonas Almqvist and Leif Ostman's account of how the manner of teaching can strongly influence pupil learning by recommending video supported reflection as a means by which teachers can transform the nature of their practice. Given the complex nature of the many conditions which influence and control teachers' actions the reframing of routine practice through reflection-in-action can prove challenging. This response paper describes how video can empower teachers to take greater control of their progress and allows for a more social constructivist approach to professional development. Along with a consideration of the difficulties associated with the notion of `reflection' and a short case study, the paper uses Lev Semenovich Vygotsky's zone of proximal development and the notion of scaffolding to propose that video offers a Video Supported Zone of Proximal Development which can ease the process of teacher development. In capturing permanent and exchangeable representations of practice video encourages a collaborative approach to reflection and is consistent with the original ideas of John Dewey.

  11. Quark Deconfinement in Rotating Neutron Stars

    2017-01-01

    Full Text Available In this paper, we use a three flavor non-local Nambu–Jona-Lasinio (NJL model, an improved effective model of Quantum Chromodynamics (QCD at low energies, to investigate the existence of deconfined quarks in the cores of neutron stars. Particular emphasis is put on the possible existence of quark matter in the cores of rotating neutron stars (pulsars. In contrast to non-rotating neutron stars, whose particle compositions do not change with time (are frozen in, the type and structure of the matter in the cores of rotating neutron stars depends on the spin frequencies of these stars, which opens up a possible new window on the nature of matter deep in the cores of neutron stars. Our study shows that, depending on mass and rotational frequency, up to around 8% of the mass of a massive neutron star may be in the mixed quark-hadron phase, if the phase transition is treated as a Gibbs transition. We also find that the gravitational mass at which quark deconfinement occurs in rotating neutron stars varies quadratically with spin frequency, which can be fitted by a simple formula.

    The Picard-Lefschetz theory offers a promising tool to solve the sign problem in QCD and other field theories with complex path-integral weight. In this paper the Lefschetz-thimble approach is examined in simple fermionic models which share some features with QCD. In zero-dimensional versions of the Gross-Neveu model and the Nambu-Jona-Lasinio model, we study the structure of Lefschetz thimbles and its variation across the chiral phase transition. We map out a phase diagram in the complex four-fermion coupling plane using a thimble decomposition of the path integral, and demonstrate an interesting link between anti-Stokes lines and Lee-Yang zeros. In the case of nonzero mass, it is shown that the approach to the chiral limit is singular because of intricate cancellation between competing thimbles, which implies the necessity to sum up multiple thimbles related by symmetry. We also consider a Chern-Simons theory with fermions in 0+1-dimension and show how Lefschetz thimbles solve the complex phase problem caused by a topological term. These prototypical examples would aid future application of this framework to bona fide QCD.

    Full Text Available This article describes a manuscript book Ułamki…, dated to 1855. This silva rerum, created in a rural environment, continues in a peculiar way the traditi­on of manuscripts prepared outside the limits of of­ficial institutions. Ułamki… was prepared within the textual community of the Baranauskas family. This community encompasses the Baranauskas family, and its structure repeats the patriarchic model of a family. Antanas and Anupras Baranauskas – authors of Ułamki… – dedicate this silva rerum to Jonas Ba­ranauskas – the central figure of this textual commu­nity as well as the head of the family.The part prepared by Anupras Baranauskas is composed of texts and drawings (sketches for art lessons and maps which come from his school ye­ars. The part by Antanas Baranauskas is composed of poems authored by himself, which might be read as a story of his attempts to secure a position of a scri­be as close to home as possible. Both parts include variations on the theme of tension between estrange­ment and identity. The book itself is understood as an effort to overcome this opposition by means of a written text as well as to vindicate identity and extant links within the textual community and at the same time the family. It is this effort that provides unity to this book, which prima facie seems rather diffuse.

    Full Text Available As Manuel de Solà-Morales noted, urbanity relies on the variety and quality of relations between things, materials and human beings. Considered as such, how are we to achieve an underground urbanity? This paper seeks to address this question through a focussed reading of a number of European urban projects from the 20th century; all of which put special care into ensuring the quality of their subterranean passageways. We begin with the carrefour à giration, which was designed by Eugène Hénard in 1906, in order to identify four fundamental attributes of this kind of urbanity: legibility, spatiality, accessibility and activity. We then continue with a qualitative analysis of the 1933 Blå Bodarna passageway designed by Tage William-Olsson and Holger Blom in Slussen (Stockholm. Looking ahead some decades later, the sequence of passages under the Vienna Ring, built during the mayoralty of Franz J. Jonas, provides a good example of how fundamental the connectivity to the underground public transport system was to the success of these spaces. Finally, the article closes with a review of those underground places found in Santiago Calatrava’s Stadelhofen Station and the Stationsplein by Manuel de Solà-Morales: from the carrefour à étages multiples to the ‘inner street’.

    Full Text Available We first examine the scaling argument for a renormalization-group (RG analysis applied to a system subject to the dimensional reduction in strong magnetic fields, and discuss the fact that a four-Fermi operator of the low-energy excitations is marginal irrespective of the strength of the coupling constant in underlying theories. We then construct a scale-dependent effective four-Fermi interaction as a result of screened photon exchanges at weak coupling, and establish the RG method appropriately including the screening effect, in which the RG evolution from ultraviolet to infrared scales is separated into two stages by the screening-mass scale. Based on a precise agreement between the dynamical mass gaps obtained from the solutions of the RG and Schwinger–Dyson equations, we discuss an equivalence between these two approaches. Focusing on QED and Nambu–Jona-Lasinio model, we clarify how the properties of the interactions manifest themselves in the mass gap, and point out an importance of respecting the intrinsic energy-scale dependences in underlying theories for the determination of the mass gap. These studies are expected to be useful for a diagnosis of the magnetic catalysis in QCD.

    Quantum Chromodynamics (QCD) is the theory of the strong interaction within the Standard Model of elementary particles. Today's research in this area dedicates substantial resources to numeric solutions of the QCD field equations and experimental programs exploring the phases of QCD. This thesis proceeds along a complementary line - that of modelling QCD, with the aim of identifying its dominant degrees of freedom. This is possible by minimally coupling effective potentials for the Polyakov loop to Nambu-Jona-Lasinio models using temporal background fields to model chiral symmetry breaking respecting colour confinement. The fermion sign problem resulting from the minimal coupling is addressed in this work establishing a novel, systematically ordered approach. The modifications to the approximative order parameter of colour confinement, the Polyakov loop, are in direct connection with the fermion sign problem. Furthermore an effective coupling of quark densities of different flavours is induced. This mechanism, most likely also present in QCD, produces finite contributions to flavour off diagonal susceptibilities. Susceptibilities are amongst the most promising physical quantities for the experimental exploration of the phase transition at high temperatures and densities. (orig.)

    The discovery of pulsars PSR J1614-2230 and PSR J0348+0432 with masses of around 2 M⊙ imposes strong constraints on the equations of state of cold, ultradense matter. If a phase transition from hadronic matter to quark matter were to occur in the inner cores of such massive neutron stars, the energetically favorable state of quark matter would be a color superconductor. In this study, we analyze the stability and maximum mass of such neutron stars. The hadronic phase is described by nonlinear relativistic mean-field models, and the local Nambu-Jona Lasinio model is used to describe quark matter in the 2SC+s quark phase. The phase transition is treated as a Maxwell transition, assuming a sharp hadron-quark interface, and the "constant-sound-speed" (CSS) parametrization is employed to discuss the existence of stellar twin configurations. We find that massive neutron stars such as J1614-2230 and J0348+0432 can only exist on the connected stellar branch but not on the disconnected twin-star branch. The latter can only support stars with masses that are strictly below 2 M⊙ .

  1. Functional Integral Approaches to the Bosonization of Effective Multi-Quark Interactions with U_A(1 Breaking

    Directory of Open Access Journals (Sweden)

    Brigitte Hiller

    2006-02-01

    Full Text Available Low energy hadron phenomenology involving the (u,d,s quarks is often approached through effective multi-quark Lagrangians with the symmetries of QCD. A very successful approach consists in taking the four-quark Nambu--Jona-Lasinio Lagrangianwith the chiral $U_L(3imes U_R(3$ symmetry in the massless limit, combined with the $U_A(1$ breaking six-quark flavourdeterminant interaction of 't Hooft. We review the present status and some very recent developments related to the functionalintegration over the cubic term in auxiliary mesonic variables that one introduces to bosonize the system. Various approaches forhandling this functional, which cannot be integrated exactly, are discussed: the stationary phase approximation, the perturbative expansion, the loop expansion, their interrelation and importance for the evaluation of the effective action. The intricate group structure rules out the method of Airy's integral. The problem ofthe instability of the vacuum is stated and a solution given by including eight-quark interactions.

  2. Low-Energy Electron Diffraction Study of the Adsorption Geometry for Pb(111)-(3x3)R30^o-K

    Both the clean Pb(111) structure and the (3x3)R30^o structure formed by potassium adsorbed on Pb(111) have been investigated by dynamical low-energy electron diffraction (LEED). The relaxation of the topmost lead layers of the clean Pb(111) surface is the main deviation from the bulk geometry, in agreement to the results of a similar study [Y.S. Li, F. Jona, P.M. Marcus, Phys. Rev. B 43 (1991) 6337]. Upon adsorption of K at room temperature, a (3x3)R30^o structure is formed with K atoms occupying substitution sites. This result is rather unexpected considering that intermixing is unusual for large alkalis (larger than Li) adsorbed on close-packed substrates. The current calculation finds a K-Pb bond length of 3.62±0.3å, with no significant change to the Pb interlayer spacings [F.M. Pan, M. Caragiu, N. Ferralis, R.D. Diehl, Surf. Sci. 600 (2006) 537].

    Intermixed structures for alkalis (larger than Li) on close-packed substrates have previously been observed only on Al(1 1 1). This study shows that K forms an ordered intermixed structure on Pb(1 1 1). The structures of clean Pb(1 1 1) and Pb(1 1 1)-(√3 × √3)R30°-K were studied using dynamical low-energy electron diffraction (LEED). The clean Pb(1 1 1) surface at 47 K was found to be a relaxed version of the bulk structure, in agreement with an earlier study of the same surface [Y.S. Li, F. Jona, P.M. Marcus, Phys. Rev. B 43 (1991) 6337]. At room temperature, adsorption of K on this surface results in a (√3 × √3)R30° structure, which was shown using dynamical LEED to consist of K atoms substituted in surface vacancies. The K-Pb bond length was found to be 3.62 ± 0.3 Å, with no significant change to the Pb interlayer spacings.

    A modified version of PQCD considered in previous works is investigated here in the case of retaining only the quark condensate. The Green function generating functional is expressed in a form in which Dirac's delta functions are now absent from the free propagators. The new expansion implements the dimensional transmutation effect through a single interaction vertex in addition to the standard ones in massless QCD. The new vertex suggest a way for constructing an alternative to the SM, in which the mass and CKM matrices could be generated by the instability of massless QCD under the production of the top quark and other fermions condensates, in a kind of generalized Nambu-Jona-Lasinio mechanism. The results of a two loop evaluation of the vacuum energy indicate that the quark condensate is dynamically generated. However, the energy as a function of the condensate parameter is again unbounded from below in this approximation. Assuming the existence of a minimum of the vacuum energy at the experimental value of the top quark mass m{sub q} =173 GeV, we evaluate the two particle propagator in the quark-anti-quark channel in zero order in the coupling and a ladder approximation in the condensate vertex. Adopting the notion from the former top quark models in which the Higgs field corresponds to the quark condensate, the results suggest that the Higgs particle could be represented by a meson which might appear at energies around twice the top quark mass.

    We have lost one of the giants of the twentieth century physics when Yoichiro Nambu passed away in July, 2015, at the age of 94. Today's Standard Model, though still incomplete in many respects, is the culmination of the most successful theory of the Universe to date, and it is built upon foundations provided by discoveries made by Nambu in the 1960s: the mechanism of spontaneously broken symmetry in Nature (with G Jona-Lasinio) and the hidden new SU(3) symmetry of quarks and gluons (with M-Y Han). In this volume honoring Nambu's memory, World Scientific Publishing presents a unique collection of papers written by his former colleagues, collaborating researchers and former students and associates, not only citing Nambu's great contributions in physics but also many personal and private reminiscences, some never told before. This volume also contains the very last scientific writing by Professor Nambu himself, discussing the development of particle physics. This book is a volume for all who benefited not on...

    1997-06-01

    According to the WHO Program, nurses should be active in public health care as equal members of a multiprofessional team. This position requires competent professional action, which also implies moral competence, especially necessitated by the coming paradigmatic changes caused by shifts in the previous and current boundaries of the paradigm human being. One reason for this shift are the greater medical technical possibilities. The medical definition of brain death as the death of a human being per se is one example of the altered boundary and its consequences. Must future components of the nursing metaparadigm be changed because of this? To what extent is nursing ethically obligated to integrate changes in social values into its metaparadigm, ethics and objectives? The nursing metaparadigm, Henderson's definition of nursing, the ICN's Basic Code of Ethics, and the nursing model according to Roper, Logan & Tierney were used as the basis in the analysis of the subject matter and problems. Furthermore, philosophical viewpoints of Jonas & Harris will be included to clarify the deontological and teleological aspects of standard ethics. Finally, conclusions are drawn about the intra- and interprofessional ethical discourse about brain death and organ transplantation among nursing professionals.

Assim, a vulnerabilidade da natureza aparece num contexto niilista, quer dizer, desprovida de qualquer limite ontológico e axiológico. A ética proposta por Hans Jonas está fundamentada sobre a concepção teleológica da natureza, entendida como um valor que interpela a responsabilidade do homem para que ele se torne responsável pela sua preservação. Este novo conceito de responsabilidade já não se fundamenta apenas no nexo causal que vincula o sujeito a suas ações, mas sim, no ser valioso e vulnerável do qual surge uma exigência ética que nos compele a sermos responsável por ele.

    As physicians, we've all learned in detail about the science behind vaccinations, but I suspect few of us have been taught about the history of vaccinations. Sure, we all know that Dr. Jonas Salk developed the poliovirus vaccine, but I wasn't aware that he inoculated himself, his wife, and his three children with his then experimental vaccine. When our editorial committee decided to focus on vaccinations as our theme for this month's Greene County Medical Society's Journal, I perused the internet for interesting topics. I came across a fascinating website, historyofvaccines.org; this website is a project of the College of Physicians of Philadelphia, touted as being the oldest professional medical organization in the United States. I credit the majority of the information in this article to the above website and the rest to the National Institutes of Health (nih.gov) website; I trust that the information is valid and true, based on the agencies behind these websites. Below are some interesting tidbits about vaccine preventable diseases that I found noteworthy to pass on to our readers.

    2013-05-06

    In this work we present the features of the hadron-quark phase transition diagrams in which the pions are included in the system. To construct such diagrams we use two different models in the description of the hadronic and quark sectors. At the quark level, we consider two distinct parametrizations of the Polyakov-Nambu-Jona-Lasinio (PNJL) models. In the hadronic side, we use a well known relativistic mean-field (RMF) nonlinear Walecka model. We show that the effect of the pions on the hadron-quark phase diagrams is to move the critical end point (CEP) of the transitions lines. Such an effect also depends on the value of the critical temperature (T{sub 0}) in the pure gauge sector used to parametrize the PNJL models. Here we treat the phase transitions using two values for T{sub 0}, namely, T{sub 0}= 270 MeV and T{sub 0}= 190 MeV. The last value is used to reproduce lattice QCD data for the transition temperature at zero chemical potential.

    -generated reactive species are used to initiate chemical reactions at unexpectedly lower temperatures than conventional thermochemical reactions, leading to non-equilibrium product distribution or creating unconventional reaction pathways. When non-thermal plasma is combined with catalysts, a synergistic effect is frequently observed. Such unique properties of non-thermal plasma are expected to contribute excellent control over process parameters that meet the need for energy saving, environment protection, and material preservation. This special issue consists of eleven peer-reviewed papers including two invited publications. Professors Alexander Fridman and Alexander Rabinovich from Drexel University, and Dr Gutsol from the Chevron Energy Technology Company present a critical review of various industry-oriented practical plasma fuel conversion processes. Professor Richard Mallinson from University of Oklahoma describes his recent project on E85 (85%-ethanol/15%-gasoline) upgrading using non-thermal plasma and catalyst hybrid reactor, and highlights the synergistic effect on fuel conversion processes. Other papers focus on plasma/catalyst hybrid reactions for methane dry (CO2) reforming, plasma synthesis of carbon suboxide polymer from CO, the gas-to-liquid (GTL) process using a non-thermal plasma-combined micro-chemical reactor, and molecular beam characterization of plasma-generated reactive species. Much research regarding plasma catalysis is ongoing worldwide, but there is plenty of room for further development of plasma fuel processing, which could eventually provide a viable and flexible solution in future energy and material use. Finally, we would like to thank all symposium participants for their active discussion. We appreciate the sponsorship of the Division of Fuel Chemistry of the American Chemical Society.

    The move of computational genomics workflows to Cloud Computing platforms is associated with a new level of integration and interoperability that challenges existing data representation formats. The Variant Calling Format (VCF) is in a particularly sensitive position in that regard, with both clinical and consumer-facing analysis tools relying on this self-contained description of genomic variation in Next Generation Sequencing (NGS) results. In this report we identify an isomorphic map between VCF and the reference Resource Description Framework. RDF is advanced by the World Wide Web Consortium (W3C) to enable representations of linked data that are both distributed and discoverable. The resulting ability to decompose VCF reports of genomic variation without loss of context addresses the need to modularize and govern NGS pipelines for Precision Medicine. Specifically, it provides the flexibility (i.e. the indexing) needed to support the wide variety of clinical scenarios and patient-facing governance where only part of the VCF data is fitting. Software libraries with a claim to be both domain-facing and consumer-facing have to pass the test of portability across the variety of devices that those consumers in fact adopt. That is, ideally the implementation should itself take place within the space defined by web technologies. Consequently, the isomorphic mapping function was implemented in JavaScript, and was tested in a variety of environments and devices, client and server side alike. These range from web browsers in mobile phones to the most popular micro service platform, NodeJS.

    Full Text Available The article discusses the short-term “project” – to write Lithuanian mythology of one of the most influential public organisations of the 19th century in Vilnius – shubravci, which was close to masons. The majority of shubravci were quite positive about the “project” – Poles, Vilnius University professors – and chose pseudonyms of Lithuanian mythology characters by making a promise to collect material about each character. This rather marginal project among such people – the writing of mythology – was discussed in the publication Street News, Wiadomości brukowe, the official approach of the union to this idea from very enthusiastic transformed into very unacceptable and even became the object of mockery. However, the impulse of shubravci was captured by a lot of Lithuanians of the first quarter of the 19th century; later this idea was developed from Simonas Daukantas to Kajetonas Neazabitauskis, from D. Poška, to whom the idea of Vilnius professors became a “lightning-conductor” to his previous works. This idea among shubravci was supported by two persons – K. Kontrimas ir J. Šimkevičius; reaction in the union itself was fast, the idea was abandoned and suppressed. We can also observe the moment when processes which led to T. Narbutas, J. I. Kraševskis, S. Daukantas till Jonas Basanavičius ideology; the processes which contributed to the birth of liberation ideology at the beginning of XX century and were reiterated in the 20th century in Romuva and Ethos ideology line, which is still alive.

  17. Effective field theories of baryons and mesons, or, what do quarks do?

    This thesis is an attempt to understand the properties of the protons, pions and other hadrons in terms of their fundamental building blocks. In the first chapter the author reviews several of the approaches that have already been developed. The Nambu-Jona-Lasinio model offers the classic example of a derivation of meson properties from a quark Lagrangian. The chiral quark model encodes much of the intuition acquired in recent decades. The author also discusses the non-linear sigma model, the Skyrme model, and the constituent quark model, which is one of the oldest and most successful models. In the constituent quark model, the constituent quark appears to be different from the current quark that appears in the fundamental QCD Lagrangian. Recently it was proposed that the constituent quark is a topological soliton. In chapter 2 the author investigates this soliton, calculating its mass, radius, magnetic moment, color magnetic moment, and spin structure function. Within the approximations used, the magnetic moments and spin structure function cannot simultaneously be made to agree with the constituent quark model. In chapter 3 the author uses a different plan of attack. Rather than trying to model the constituents of the baryon, he begins with an effective field theory of baryons and mesons, with couplings and masses that are simply determined phenomenologically. Meson loop corrections to baryon axial currents are then computed in the 1/N expansion. It is already known that the one-loop corrections are suppressed by a factor 1/N; here it is shown that the two-loop corrections are suppressed by 1/N{sup 2}. To leading order, these corrections are exactly the same as would be calculated in the constituent quark model. This method therefore offers a different approach to the constituent quark.

    Full Text Available Los riesgos para la salud asociados al cambio climático son múltiples y afectan particularmente a aquellas pobla-ciones en condiciones de pobreza. Con base en la lectura y análisis crítico de publicaciones científicas vinculadas al cambio climático y la salud, en este artículo se propone el objetivo de responder a la pregunta acerca de qué valores y derechos humanos podría estar problematizando el cambio climático en relación con el ser humano.Los determinantes de salud generados por el cambio climático limitarían potencialmente las capacidades humanas, entendidas por Martha Nussbaum como manifestación de la libertad humana para ser y hacer.También se menciona el pensamiento de Hans Jonas en relación con la necesidad de tener temor por las conse-cuencias de una falta de acción. Se concluye, finalmente, que los profundos cambios contextuales asociados al cambio climático deberían promover la pregunta acerca de sus potenciales efectos a nivel del neurodesarrollo de los niños que viven en zonas de desastres asociados a este. Simultáneamente, en una perspectiva donde convergen la bioética y la neuroética, el cambio climático resaltaría la responsabilidad que los seres humanos individual y colectivamente tenemos en la construcción de las condiciones presentes y futuras del desarrollo infantil, y particularmente cuando este se da en condiciones de pobreza.

    Accurate forecast of sea-level heights in coastal areas depends, among other factors, upon a reliable coupling of a meteorological forecast system to a hydrodynamic and wave system. This study evaluates the predictive skills of the coupled circulation and wind-wave model system (ADCIRC+SWAN) for simulating storm tides in the Chesapeake Bay, forced by six different products: (1) Global Forecast System (GFS), (2) Climate Forecast System (CFS) version 2, (3) North American Mesoscale Forecast System (NAM), (4) Rapid Refresh (RAP), (5) European Center for Medium-Range Weather Forecasts (ECMWF), and (6) the Atlantic hurricane database (HURDAT2). This evaluation is based on the hindcasting of four events: Irene (2011), Sandy (2012), Joaquin (2015), and Jonas (2016). By comparing the simulated water levels to observations at 13 monitoring stations, we have found that the ADCIR+SWAN System forced by the following: (1) the HURDAT2-based system exhibited the weakest statistical skills owing to a noteworthy overprediction of the simulated wind speed; (2) the ECMWF, RAP, and NAM products captured the moment of the peak and moderately its magnitude during all storms, with a correlation coefficient ranging between 0.98 and 0.77; (3) the CFS system exhibited the worst averaged root-mean-square difference (excepting HURDAT2); (4) the GFS system (the lowest horizontal resolution product tested) resulted in a clear underprediction of the maximum water elevation. Overall, the simulations forced by NAM and ECMWF systems induced the most accurate results best accuracy to support water level forecasting in the Chesapeake Bay during both tropical and extra-tropical storms.

    Full Text Available Results of measurements and visual observations of aurora at Spitsbergen, carried out by the joint Swedish-Russian expedition during 1899–1900, are described. Auroral observations took place during the great bilateral Arc-of-Meridian expedition, which was patronized by the Swedish Royal Family and the Russian Imperial Family. The Russian-Swedish Arc-of-Meridian measurements were closely coordinated but auroral measurements from the two sites in the Spitsbergen Archipelago were almost independent of each other. The basic auroral data for our presentation are reports of the Russian astronomer Josef Sykora and the Swedish geophysicist Jonas Westman. Both scientists used similar types of photo cameras and spectrographs, which were the best at that time and were made in Potsdam by Toepfer. Detailed descriptions of the optical devices and the system of spectral calibration are presented. A Toepfer spectrograph, possibly the one used by Westman, is still kept at IRF in Kiruna. We present a comparative analysis of auroral data from the Russian and Swedish stations on three themes: visual observations of aurora, describing features of auroral forms and giving us statistical data on aurora occurrence and the heights of aurora, photos of aurora, and auroral spectra. It is shown that the observations contain enough data to construct an auroral oval and to determine the heights of aurora. The expedition obtained the first photographic observations of the aurora in the Arctic. The auroral spectra demonstrate a high spectral resolution and show not only the main auroral emissions in the blue-green spectral range but also some weak emissions in the violet and ultraviolet region. All data are interpreted from a modern point of view. The Russian-Swedish 1899–1900 expedition carried out the first complex auroral investigations in the Arctic using optical instruments and presented well documented data and new results.

    In recent years our understanding of neutron stars has advanced remarkably, thanks to research converging from many directions. The importance of understanding neutron star behavior and structure has been underlined by the recent direct detection of gravitational radiation from merging neutron stars. The clean identification of several heavy neutron stars, of order two solar masses, challenges our current understanding of how dense matter can be sufficiently stiff to support such a mass against gravitational collapse. Programs underway to determine simultaneously the mass and radius of neutron stars will continue to constrain and inform theories of neutron star interiors. At the same time, an emerging understanding in quantum chromodynamics (QCD) of how nuclear matter can evolve into deconfined quark matter at high baryon densities is leading to advances in understanding the equation of state of the matter under the extreme conditions in neutron star interiors. We review here the equation of state of matter in neutron stars from the solid crust through the liquid nuclear matter interior to the quark regime at higher densities. We focus in detail on the question of how quark matter appears in neutron stars, and how it affects the equation of state. After discussing the crust and liquid nuclear matter in the core we briefly review aspects of microscopic quark physics relevant to neutron stars, and quark models of dense matter based on the Nambu- Jona-Lasinio framework, in which gluonic processes are replaced by effective quark interactions. We turn then to describing equations of state useful for interpretation of both electromagnetic and gravitational observations, reviewing the emerging picture of hadron-quark continuity in which hadronic matter turns relatively smoothly, with at most only a weak first order transition, into quark matter with increasing density... © 2018 IOP Publishing Ltd.

    When Jonas Salk announced in the mid-50s the availability of a new vaccine against poliomyelitis, the world had the impression that it was now controlling infectious diseases. In fact, the success of this vaccine has been considerable and although some innovations lead to the launch of vaccines against flu, measles, rubella or mumps, the world vaccine market remained remarkably stable till the mid-80s. However, since 1984 (launch of the hepatitis B vaccine) there have been very substantial changes and further change is expected in the next ten years in the world market. Today, big companies are making a concentrated supply: Pasteur Mérieux with its subsidiary Connaught, SmithKline Beecham who acquired the Belgian company RIT, and Merck & Co. who is joining its forces with Pasteur Mérieux. Medium sized and small companies remain and reflect the situation of the past, but must work hard to secure their long term existence eventhough the world demand is going to double before the year 2000. Very substantial technological innovations explain to a large extent the development of the supply: progress in molecular biology, and particularly genetic engineering, lead to recombinant vaccines of which hepatitis B is the best example with worldwide sales in the range of $600 million a year. Similarly, conjugation technologies have allowed the development of new vaccines against meningitis, particularly Haemophilus influenzae type b. More recently, an efficacious vaccine against hepatitis A has been launched and many new products will be marketed in the next years against herpes, Lyme disease, and agents of other meningitis, etc.(ABSTRACT TRUNCATED AT 250 WORDS)

    Numerous theoretical studies using various equation of state models have shown that quark matter may exist at the extreme densities in the cores of high-mass neutron stars. It has also been shown that a phase transition from hadronic matter to quark matter would result in an extended mixed phase region that would segregate phases by net charge to minimize the total energy of the phase, leading to the formation of a crystalline lattice. The existence of quark matter in the core of a neutron star may have significant consequences for its thermal evolution, which for thousands of years is facilitated primarily by neutrino emission. In this work we investigate the effect a crystalline quark-hadron mixed phase can have on the neutrino emissivity from the core. To this end we calculate the equation of state using the relativistic mean-field approximation to model hadronic matter and a nonlocal extension of the three-flavor Nambu-Jona-Lasinio model for quark matter. Next we determine the extent of the quark-hadron mixed phase and its crystalline structure using the Glendenning construction, allowing for the formation of spherical blob, rod, and slab rare phase geometries. Finally we calculate the neutrino emissivity due to electron-lattice interactions utilizing the formalism developed for the analogous process in neutron star crusts. We find that the contribution to the neutrino emissivity due to the presence of a crystalline quark-hadron mixed phase is substantial compared to other mechanisms at fairly low temperatures (

    The Swedish physician, Dr Jonas Gustav W. Zander (1835-1920), set himself the task of devising different contraptions around 1860. He believed that people who needed medical gymnastics could be treated better and more efficiently with the help of machines. His mechanistic approach can be understood in the context of the emerging industrialisation that rapidly took hold in Europe in this period. After very successful presentations at the World Exhibitions in Philadelphia (1876) and in Paris (1878), the Zander-method soon caught on in the medical world and many so-called Zander-Institutes (very similar to fitness-centres today) emerged in the larger cities of a number of European countries. Zander-therapy became very popular in The Netherlands during the 1890s. The first Zander-Institute opened its doors in Groningen in 1894 to be followed, within four years, by another eight Zander-Institutes in the major cities of The Netherlands. Physical education teachers, engaging in medical gymnastics, and physicians worked closely together in these institutes. This was considered to be a positive development as medical gymnastics was a heavily contested area in the field of labour in the last quarter of the nineteenth century. After a short period of success almost all of the Zander-Institutes had great difficulty in maintaining their existence in the first decade of the twentieth century. Both the rise and fall of the Zander-Institutes can be ascribed to a combination of factors of a scientific (concerning the method), social (legislation concerning the care of the crippled) and professional (concerning the different strategies of the involved professions) nature. These factors and the relationships between them are analysed in this article.

  6. Normalization Strategies for Enhancing Spatio-Temporal Analysis of Social Media Responses during Extreme Events: A Case Study based on Analysis of Four Extreme Events using Socio-Environmental Data Explorer (SEDE)

    With social media becoming increasingly location-based, there has been a greater push from researchers across various domains including social science, public health, and disaster management, to tap in the spatial, temporal, and textual data available from these sources to analyze public response during extreme events such as an epidemic outbreak or a natural disaster. Studies based on demographics and other socio-economic factors suggests that social media data could be highly skewed based on the variations of population density with respect to place. To capture the spatio-temporal variations in public response during extreme events we have developed the Socio-Environmental Data Explorer (SEDE). SEDE collects and integrates social media, news and environmental data to support exploration and assessment of public response to extreme events. For this study, using SEDE, we conduct spatio-temporal social media response analysis on four major extreme events in the United States including the "North American storm complex" in December 2015, the "snowstorm Jonas" in January 2016, the "West Virginia floods" in June 2016, and the "Hurricane Matthew" in October 2016. Analysis is conducted on geo-tagged social media data from Twitter and warnings from the storm events database provided by National Centers For Environmental Information (NCEI) for analysis. Results demonstrate that, to support complex social media analyses, spatial and population-based normalization and filtering is necessary. The implications of these results suggests that, while developing software solutions to support analysis of non-conventional data sources such as social media, it is quintessential to identify the inherent biases associated with the data sources, and adapt techniques and enhance capabilities to mitigate the bias. The normalization strategies that we have developed and incorporated to SEDE will be helpful in reducing the population bias associated with social media data and will be useful

With this in mind, we evaluated the effect of sorafenib, a receptor tyrosine kinase inhibitor, on cell growth and apoptosis in sarcoma cell lines of various histological subtypes. We found that sorafenib effectively inhibited cell proliferation in rhabdomyosarcoma, synovial sarcoma and Ewing’s sarcoma with IC50 values <5 µM. Sorafenib effectively induced growth arrest in rhabdomyosarcoma cells, which was concurrent with inhibition of Akt and Erk signaling. Studies of ligand-induced phosphorylation of Erk and Akt in rhabdomyosarcoma cells showed that insulin-like growth factor-1 is a potent activator, which can be blocked by treatment with sorafenib. In vivo sorafenib treatment of rhabdomyosarcoma xenografts had a significant inhibitory effect on tumor growth, which was associated with inhibited vascularization and enhanced necrosis in the adjacent tumor stroma. Our results demonstrate that in vitro and in vivo growth of rhabdomyosarcoma can be suppressed by treatment with sorafenib, and suggests the possibilities of using sorafenib as a potential adjuvant therapy for the treatment of rhabdomyosarcoma.Keywords: soft tissue sarcoma, kinase inhibitors, targeted therapy, vascularization

  8. Goldstone boson condensation and effects of the axial anomaly in color superconductivity

    Energy Technology Data Exchange (ETDEWEB)

    Basler, Hannes Gregor Steffen

    2011-01-12

    One of the central objects of interest in high energy physics is the phase diagram of strongly interacting matter, the behavior of quarks and gluons in dependence of temperature and chemical potential. At very high densities and low temperatures it is expected that quarks form a superconductor, the so-called color superconductor. Such a color superconductor might be realized in the inner core of a neutron star. To study the phase structure of a color superconductor under neutron star conditions the Nambu-Jona-Lasinio model is used. The diquark condensates appearing in a color superconductor may break the original symmetries and give rise to Goldstone bosons. In this work we study the possible condensation of these Goldstone bosons. On the level of diquark condensates the condensation of Goldstone bosons is realized by a rotation of scalar into pseudoscalar diquark condensates. The phase diagram is studied, including pseudoscalar diquark condensates, for several different values of the lepton number chemical potential. The masses and thereby the condensation of the Goldstone bosons is effected by a six-point interaction that breaks the axial U(1) symmetry. Usually this six-point interaction is implemented in the NJL model in such a way that is does not effect the diquark sector. This can be fixed by adding an second six-point interaction term to the NJL Lagrangian. The coupling strength of this new interaction term has a great influence on the phase digram. In this context also the effect on the chiral phase transition is studied. (orig.)

  9. On the Nambu fermion-boson relations for superfluid 3He

    2017-03-01

    Superfluid 3He is a spin-triplet (S =1 ), p -wave (L =1 ) BCS condensate of Cooper pairs with total angular momentum J =0 in the ground state. In addition to the breaking of U(1) gauge symmetry, separate spin or orbital rotation symmetry is broken to the maximal subgroup SO (3) S×SO (3) L→SO(3 ) J . The fermions acquire mass mF≡Δ , where Δ is the BCS gap. There are also 18 bosonic excitations: 4 Nambu-Goldstone modes and 14 massive amplitude Higgs modes. The bosonic modes are labeled by the total angular momentum J ∈{0 ,1 ,2 } , and parity under particle-hole symmetry c =±1 . For each pair of angular momentum quantum numbers J ,Jz , there are two bosonic partners with c =±1 . Based on this spectrum, Nambu proposed a sum rule connecting the fermion and boson masses for BCS-type theories, which for 3He-B is MJ,+ 2+MJ,- 2=4 mF2 for each family of bosonic modes labeled by J , where MJ ,c is the mass of the bosonic mode with quantum numbers (J ,c ) . The Nambu sum rule (NSR) has recently been discussed in the context of Nambu-Jona-Lasinio models for physics beyond the standard model to speculate on possible partners to the recently discovered Higgs boson at higher energies. Here, we point out that the Nambu fermion-boson mass relations are not exact. Corrections to the bosonic masses from (i) leading-order strong-coupling corrections to BCS theory, and (ii) polarization of the parent fermionic vacuum lead to violations of the sum rule. Results for these mass corrections are given in both the T →0 and T →Tc limits. We also discuss experimental results, and theoretical analysis, for the masses of the Jc=2± Higgs modes and the magnitude of the violation of the NSR.

  10. Effective Field Theories for Hot and Dense Matter

    2010-10-01

    Full Text Available The lecture is divided in two parts. The first one deals with an introduction to the physics of hot, dense many-particle systems in quantum field theory [1, 2]. The basics of the path integral approach to the partition function are explained for the example of chiral quark models. The QCD phase diagram is discussed in the meanfield approximation while QCD bound states in the medium are treated in the rainbow-ladder approximation (Gaussian fluctuations. Special emphasis is devoted to the discussion of the Mott effect, i.e. the transition of bound states to unbound, but resonant scattering states in the continnum under the influence of compression and heating of the system. Three examples are given: (1 the QCD model phase diagram with chiral symmetry ¨ restoration and color superconductivity [3], (2 the Schrodinger equation for heavy-quarkonia [4], and (2 Pions [5] as well as Kaons and D-mesons in the finite-temperature Bethe-Salpeter equation [6]. We discuss recent applications of this quantum field theoretical approach to hot and dense quark matter for a description of anomalous J/ψ supression in heavy-ion collisions [7] and for the structure and cooling of compact stars with quark matter interiors [8]. The second part provides a detailed introduction to the Polyakov-loop Nambu–Jona-Lasinio model [9] for thermodynamics and mesonic correlations [10] in the phase diagram of quark matter. Important relationships of low-energy QCD like the Gell-Mann–Oakes–Renner relation are generalized to finite temperatures. The effect of including the coupling to the Polyakov-loop potential on the phase diagram and mesonic correlations is discussed. An outlook is given to effects of nonlocality of the interactions [11] and of mesonic correlations in the medium [12] which go beyond the meanfield description.

  11. Modeling the thermodynamics of QCD

    Hell, Thomas

    2010-07-26

    Strongly interacting (QCD) matter is expected to exhibit a multifaceted phase structure: a hadron gas at low temperatures, a quark-gluon plasma at very high temperatures, nuclear matter in the low-temperature and high-density region, color superconductors at asymptotically high densities. Most of the conjectured phases cannot yet be scrutinized by experiments. Much of the present picture - particularly concerning the intermediate temperature and density area of the phase diagram of QCD matter - is based on model calculations. Further insights come from Lattice-QCD computations. The present thesis elaborates a nonlocal covariant extension of the Nambu and Jona-Lasinio (NJL) model with built-in constraints from the running coupling of QCD at high-momentum and instanton physics at low-momentum scales. We present this model for two and three quark flavors (in the latter case paying particular attention to the axial anomaly). At finite temperatures and densities, gluon dynamics is incorporated through a gluonic background field, expressed in terms of the Polyakov loop (P). The thermodynamics of this nonlocal PNJL model accounts for both chiral and deconfinement transitions. We obtain results in mean-field approximation and beyond, including additional pionic and kaonic contributions to the chiral condensate, the pressure and other thermodynamic quantities. Finally, the nonlocal PNJL model is applied to the finite-density region of the QCD phase diagram; for three quark flavors we investigate, in particular, the dependence of the critical point appearing in the models on the axial anomaly. The thesis closes with a derivation of the nonlocal PNJL model from first principles of QCD. (orig.)

  12. Ethics Beyond Finitude: Responsibility towards Future Generations and Nuclear Waste Management

    This dissertation has three aims: 1. To evaluate several ethical theories about responsibility towards future generations. 2. To construct a theory about responsibility towards future generations. 3. To carry out an ethical evaluation of different nuclear waste management methods. Five theories are evaluated with the help of evaluative criteria, primarily: A theory must provide future generations with some independent moral status. A theory should acknowledge moral pluralism. A theory should provide some normative claims about real-world problems. Derek Parfit's theory provides future generations with full moral status. But it is incompatible with moral pluralism, and does not provide reasonable normative claims about real-world problems. Brian Barry's theory provides such claims and a useful idea about risk management, but it does not provide an argument why future generations ought to exist. Avner de-Shalit's theory explains why they ought to exist; however, his theory can not easily explain why we ought to care for other people than those in our own community. Emmanuel Agius' theory gives an ontological explanation for mankind's unity, but reduces conflicts of interests to a common good. Finally, Hans Jonas' theory shifts the focus from the situation of future generations to the preconditions of human life generally. However, his theory presupposes a specific ontology, which might be unable to motivate people to act. The concluding chapters describe a narrative theory of responsibility. It claims that we should comprehend ourselves as parts of the common story of mankind and that we ought to provide future generations with equal opportunities. This implies that we should avoid transferring risks and focus on reducing the long-term risks associated with the nuclear waste

    Full Text Available Depending on their motivation, individuals prefer different group contexts for social interactions. The present research sought to provide more insight into this relationship. More specifically, we tested how challenge / threat and a promotion / prevention focus predict attraction to groups with high or low power. As such, we examined differential outcomes of threat and prevention focus as well as challenge and promotion focus that have often been regarded as closely related. According to regulatory focus, individuals should prefer groups that they expect to feel right for them to join: Low-power groups should be more attractive in a prevention (than a promotion focus, as these groups suggest security-oriented strategies, which fit a prevention focus. High-power groups should be more attractive in a promotion (rather than a prevention focus, as these groups are associated with promotion strategies fitting a promotion focus (Sassenberg, Jonas, Shah, & Brazy, 2007. In contrast, under threat (vs. challenge, groups that allow individuals to restore their (perceived lack of control should be preferred: Low-power groups should be less attractive under threat (than challenge because they provide low resources which threatened individuals already perceive as insufficient and high-power groups might be more attractive under threat (than under challenge, because their high resources allow individuals to restore control. Two experiments (N = 140 supported these predictions. The attractiveness of a group often depends on the motivation to engage in what fits (i.e., prefer a group that feels right in the light of one’s regulatory focus. However, under threat the striving to restore control (i.e., prefer a group allowing them to change the statuts quo under threat vs. challenge overrides the fit effect, which may in turn guide individuals’ behavior in social interactions.

  14. The ethics of truth in the era of technological civilization and the information

    Full Text Available The technological civilization and information society give a lot of advantages to a modern man in various fields. However, at the same time, we do not see a decrease in hostility and injustice in the society. Moreover, technological progress has led to the fact that human civilization is on the verge of a serious challenge caused by environmental disasters and opportunity for unprecedented disastrous consequences of the World War III. In these circumstances, the search for the causes of the current crisis is actual as well as the development of concepts that can contribute to overcoming this crisis. One of the most promising theories in this context is the ethics of truth. In modern civilization the issue of the importance of truth is shifted to the periphery of the intellectual discourse. Modern civilization uses only substitutes of the issue. Veracity in science together with popular opinions in the field of information circulating are such substitutes of truth. However, these substitutes do not fully reflect the true contents of the truth issue. The truth is not confined to the veracity of a celebrity’s opinion. Analyzing the theories by H. Jonas, В. Hübner, V. Stepin and T. Voronina, the study argues that the processes of losing of the meaning of life are intensifying in the modern civilization. We argue that a lack of a proper attention in modern civilization to the issue of truth inevitably stimulates processes of diluting the meaning of human life. Based on the theories by G. Hegel, H.-G. Gadamer and J. Neidleman T. Osborne, the study demonstrates that without thinking about the issue of the truth one cannot come near to the transcendent, and thus, his life could not be convincingly endowed with meaning, fullness and a purpose of existence. Understanding the issue of truth is especially important in conditions of the modern civilization, because our civilization is facing the possibility of self-destruction as a result of its

    Full Text Available Arthur Swift,1 Erika von Grote,2 Brandie Jonas,2 Alessandra Nogueira2 1Arthur Swift Research Inc., Montreal, QC, Canada; 2Medical Affairs, Galderma Laboratories, L.P., Fort Worth, TX, USA Introduction: The appeal of hyaluronic acid fillers for facial soft tissue augmentation is attributable to both an immediate aesthetic effect and relatively short recovery time. Although recovery time is an important posttreatment variable, as it impacts comfort with appearance and perceived treatment benefit, it is not routinely evaluated. Natural-looking aesthetic outcomes are also a primary concern for many patients.Materials and methods: A single-center, noncomparative study evaluated the time (in hours until subjects return to social engagement (RtSE following correction of moderate and severe nasolabial folds (NLFs with RR (Restylane® Refyne and RD (Restylane® Defyne, respectively. Twenty subjects (aged 35–57 years who received bilateral NLF correction documented their RtSE and injection-related events posttreatment. Treatment efficacy was evaluated by improvements in Wrinkle Severity Rating Scale (WSRS and subject satisfaction questionnaire at days 14 and 30, and by Global Aesthetic Improvement Scale (GAIS at day 30. Safety was evaluated by injection-related events and treatment-emergent adverse events.Results: Fifty percent of subjects reported RtSE within 2 hours posttreatment. WSRS for the RR group improved significantly from baseline at day 14 (–1.45±0.42 and day 30 (–1.68±0.46 (P<0.001, respectively. WSRS for the RD group improved significantly from baseline at day 14 (–2.22±0.44 and day 30 (–2.50±0.50 (P<0.004, respectively. All GAIS improvements were clinically significant at day 30. The majority of injection-related events were mild or moderate. Two subjects experienced 3 related treatment-emergent adverse events; 1 RR subject experienced severe bruising, and 1 RD subject experienced severe erythema and mild telangiectasia

V/P SPECT identifies functional impairment in diseases such as heart failure (HF, pneumonia, and chronic obstructive pulmonary disease (COPD. The development of hybrid SPECT/computed tomography (CT systems, combining functional with morphological imaging through the addition of low-dose CT (LDCT, may be useful in COPD, as these patients are prone to lung cancer and other comorbidities. The aim of this study was to investigate the added value of LDCT among healthy smokers and patients with stable COPD, when examined with V/P SPECT/CT hybrid imaging. Sixty-nine subjects, 55 with COPD (GOLD I–IV and 14 apparently healthy smokers, were examined with V/P SPECT and LDCT hybrid imaging. Spirometry was used to verify COPD grade. Only one apparently healthy smoker and three COPD patients had a normal or nearly normal V/P SPECT. All other patients showed various degrees of airway obstruction, even when spirometry was normal. The same interpretation was reached on both modalities in 39% of the patients. LDCT made V/P SPECT interpretation more certain in 9% of the patients and, in 52%, LDCT provided additional diagnoses. LDCT better characterized the type of emphysema in 12 patients. In 19 cases, tumor-suspected changes were reported. Three of these 19 patients (ie, 4.3% of all subjects were in the end confirmed to have lung cancer. The majority of LDCT findings were not regarded as clinically significant. V/P SPECT identified perfusion patterns consistent with decompensated left ventricular HF in 14 COPD

Ambas as transicoes quiral e de desconfinamento na presenca de um campo magnetico externo podem ser analisadas usando os modelos de PNJL e EPNJL. Para o modelo de EPNJL e verificado que a coincidencia das temperaturas pseudocriticas de ambas as transicoes quiral e de deconfinamento dependem da parametrizacao da interacao de entanglement.

O impacto de um campo magnetico externo no comportamento do quark estranho e analizado detalhadamente. E mostrado que a temperatura pseudocritica associada a transicao quiral do quark estranho e pouco sensivel a presenca de um campo magnetico externo. Alem disso, a sua grande massa corrente torna o quark estranho pouco sensivel ao termo de 't Hooft, contrariamente a forte influencia que tem nos quarks leves. Ambos os modelos de PNJL e EPNJL preveem o efeito de Catalise Magnetica a qualquer temperatura, mas nao reproduzem o efeito de Catalise Magnetica Inversa (CMI) em redor da temperatura pseudocritica de transicao, obtido em resultados recentes da LQCD. Mostramos que e possivel reproduzir a CMI se a intensidade da interacao entre quarks diminuir com o campo magnetico. Propomos dois mecanismos que reproduzem o efeito de CMI, que assumem o enfraquecimento da constante de acoplamento da interacao escalar com o aumento da intensidade do campo magnetico.

  1. Psychosomatic medicine and the philosophy of life

    Basing ourselves on the writings of Hans Jonas, we offer to psychosomatic medicine a philosophy of life that surmounts the mind-body dualism which has plagued Western thought since the origins of modern science in seventeenth century Europe. Any present-day account of reality must draw upon everything we know about the living and the non-living. Since we are living beings ourselves, we know what it means to be alive from our own first-hand experience. Therefore, our philosophy of life, in addition to starting with what empirical science tells us about inorganic and organic reality, must also begin from our own direct experience of life in ourselves and in others; it can then show how the two meet in the living being. Since life is ultimately one reality, our theory must reintegrate psyche with soma such that no component of the whole is short-changed, neither the objective nor the subjective. In this essay, we lay out the foundational components of such a theory by clarifying the defining features of living beings as polarities. We describe three such polarities: 1) Being vs. non-being: Always threatened by non-being, the organism must constantly re-assert its being through its own activity. 2) World-relatedness vs. self-enclosure: Living beings are both enclosed with themselves, defined by the boundaries that separate them from their environment, while they are also ceaselessly reaching out to their environment and engaging in transactions with it. 3) Dependence vs. independence: Living beings are both dependent on the material components that constitute them at any given moment and independent of any particular groupings of these components over time. We then discuss important features of the polarities of life: Metabolism; organic structure; enclosure by a semi-permeable membrane; distinction between "self" and "other"; autonomy; neediness; teleology; sensitivity; values. Moral needs and values already arise at the most basic levels of life, even if only human

Several studies have established the relevance of the JNK pathway in inflammatory bowel diseases. The present study analyzed the therapeutic effect of D-JNKI-1, a specific JNK-inhibiting peptide, in a low-dose dextran sulfate sodium (DSS model of chronic colitis. Methods: DSS colitis was induced in female C57/BL6 mice by cyclic administration using different concentrations of DSS (1.0% and 1.5%. Mice in the intervention groups received subcutaneous administration of 1 µg/kg D-JNKI-1 on days 2, 12, and 22. They were monitored daily to assess the severity of colitis, body weight, stool consistency, and the occurrence of occult blood or gross rectal bleeding using evaluation of the disease activity index. The animals were sacrificed after 30 days, and the inflamed intestine was histologically evaluated using a crypt damage score. Immunohistochemical quantification of CD4+ and CD8+ cells was also carried out. Results: Administration of 1 µg/kg D-JNKI-1 resulted in a significant decrease in the disease activity index (P = 0.013 for 1.0% DSS; P = 0.007 for 1.5% DSS. As a mild form of colitis was induced, histological examination did not show any distinct damage to the mucosa and crypts. However, expression of CD4+ and CD8+ cells was reduced in mice treated with D-JNKI-1 (not

Bretkūnas translated the Bible from different German editions of M. Luther's Bible, but the Gospel according to Luke was translated from Latin and afterwards corrected with reference to the version of M. Luther.In order to establish the relation of the prepositional phrases of the Gospel according to Luke with J. Bretkūnas’ translation all the correspondences of Latin prepositional phrases were classified according to the forms of the Latin text. The unprepositional case forms in the 16th century were still used in cer­tain meanings in the cases where nowadays the prepositional phrases predominate. The said status is quite obviously observed in J. Bretkūnas’ translation where 1/4 of Latin prepositional phrases are trans­lated using different variants of the postpositional Locative, i.e. Innesive, Illative, Adessive, Allative. In the present paper we discuss the Inessive. 219 Latin prepositional phrases are translated using the Inessive. The following relations between the Vulgate’s prepositional phrases and the unprepositional Inessive can be stated:1. in + Abl mostly corresponds to the Lithuanian Iness.2. in+Acc. is translated by using the Iness. only in the cases where verbs with the indirective valency are used by J. Bretkūnas.3. When denoting the processes in the mind of person(s the Iness. corresponds to prepositional phrases apud+Acc, inter + Ace, intra + Ace, and partly in +Abl.4. The Iness. with temporal meanings is used in translation of prepositional phrases in+Abl., where the noun denotes temporal concepts. The correspondences show the synonymy of the temporal Iness. and the Instrumental in Old Lithuanian.5.

    Full Text Available Configura-se esta pesquisa em um estudo de cunho qualitativo e caráter bibliográfico, a qual almeja examinar a interrelação entre a gestão dos processos de adaptação social e o princípio da responsabilidade. Entende-se que se adentra em temática ampla e complexa, que perpassa todas as esferas do espaço público, visto que o fomento ao meio ambiente ecologicamente equilibrado afeta a todos os indivíduos, global e indistintamente. Nesse plano, mesmo sendo esta uma problemática mundial e que, consequentemente, requer uma solução abrangente, mostra-se indispensável que sejam buscadas alternativas já em âmbito local, pois é assim que se vai galgando o esclarecimento e a conscientização de todos os sujeitos. Para que o objetivo primordial desta investigação fosse alcançado utilizaram-se as concepções, de modo precípuo, de Anthony Giddens, quando este trata, especificamente, do manejo das complexidades sociais e econômicas introduzidas pelas novas formas de tecnologia, bem como a interconexão dos riscos a serem assumidos com o princípio de responsabilidade proposto por Hans Jonas. Dada a complexidade destas temáticas, o que se percebe é uma apatia social, em que a indiferença se faz, paulatinamente, mais presente. No entanto, é essencial compreender que, para haver a desobstaculização das problemáticas ainda arraigadas, a fim de almejar uma sociedade mais igual e mais responsável pelo meio ambiente, mostra-se crucial uma reformulação na práxis política, social e cultural. É mediante o engajamento político e o ativismo dos grupos sociais que se pode propor mudanças estruturais.

  7. Living without supersymmetry—the conformal alternative and a dynamical Higgs boson

    Mannheim, Philip D.

    2017-11-01

    We show that the key results of supersymmetry can be achieved via conformal symmetry instead. We propose that the Higgs boson be a dynamical fermion-antifermion bound state rather than an elementary scalar field, so that there is then no quadratically divergent self-energy problem for it and thus no need to invoke supersymmetry to resolve the problem. To obtain such a dynamical Higgs boson we study a conformal invariant gauge theory of interacting fermions and gauge bosons. The conformal invariance of the theory is realized via scaling with anomalous dimensions in the ultraviolet, and by a dynamical symmetry breaking via fermion bilinear condensates in the infrared, a breaking in which the dynamical dimension of the composite operator \\bar{\\psi }\\psi is reduced from three to two. With this reduction in dimension we can augment the gauge theory with a four-fermion interaction made renormalizable by this reduction, and can reinterpret the theory as a renormalizable version of the Nambu-Jona-Lasinio (NJL) model, with the gauge theory sector with its now massive fermion being a mean-field theory and the four-fermion interaction being the residual interaction. It is this residual interaction and not the mean field that then generates dynamical Goldstone and Higgs states, states that, as noted by Baker and Johnson, the gauge theory sector itself does not possess. The Higgs boson is found to be a narrow resonance just above threshold, with its width potentially being a diagnostic that could distinguish a dynamical Higgs boson from an elementary one. We couple the theory to a gravity theory, conformal gravity, that is equally conformal invariant, with the interplay between conformal gravity and the four-fermion interaction taking care of the vacuum energy problem. With conformal gravity being a unitary and renormalizable quantum theory of gravity there is no need for string theory with its supersymmetric underpinnings. With the vacuum energy problem being resolved and

    We consider a vectorlike gauge theory of fermions that confines at the multi-TeV scale, and that realizes the Higgs particle as a composite Goldstone boson. The weak interactions are embedded in the unbroken subgroup S p (4 ) of a spontaneously broken S U (4 ) flavor group. The meson resonances appear as poles in the two-point correlators of fermion bilinears, and include the Goldstone bosons plus a massive pseudoscalar η', as well as scalars, vectors and axial vectors. We compute the mass spectrum of these mesons, as well as their decay constants, in the chiral limit, in the approximation where the hypercolor S p (2 N ) dynamics is described by four-fermion operators, à la Nambu-Jona Lasinio. By resumming the leading diagrams in the 1 /N expansion, we find that the spin-one states lie beyond the LHC reach, while spin-zero electroweak-singlet states may be as light as the Goldstone-boson decay constant, f ˜1 TeV . We also confront our results with a set of available spectral sum rules. In order to supply composite top-quark partners, the theory contains additional fermions carrying both hypercolor and ordinary color, with an associated flavor symmetry-breaking pattern S U (6 )/S O (6 ). We identify and analyze several nontrivial features of the complete two-sector gauge theory: the 't Hooft anomaly matching conditions; the higher-dimension operator which incorporates the effects of the hypercolor axial-singlet anomaly; the coupled mass-gap equations; the mixing between the singlet mesons of the two sectors, resulting in an extra Goldstone boson η0, and novel spectral sum rules. Assuming that the strength of the four-fermion interaction is the same in the two sectors, we find that the colored vector and scalar mesons have masses ≳4 f , while the masses of colored pseudo-Goldstone bosons, induced by gluon loops, are ≳1.5 f . We discuss the scaling of the meson masses with the values of N , of the four-fermion couplings, and of a possible fermion mass.

  10. Integrating out the Dirac sea

    We introduce a new method for dealing with fermionic quantum field theories amenable to a mean-field-type approximation. In this work we focus on the relativistic Hartree approximation. Our aim is to integrate out the Dirac sea and derive a no-sea effective theory'' with positive energy single particle states only. As the derivation of the no-sea effective theory involves only standard Feynman diagrams, our approach is quite general and not restricted to particular space-time dimensions. We develop and illustrate the approach in the ''large N'' limit of the Gross-Neveu model family in 1+1 dimensions. As the Gross-Neveu model has been intensely studied and several analytical solutions are known for this model, it is an ideal testing ground for our no-sea effective theory approach. The chiral Gross-Neveu model, also referred to as 1+1 dimensional Nambu-Jona-Lasinio model, turns out to be of particular interest. In this case, we explicitly derive a consistent effective theory featuring both elementary ''{pi} meson'' fields and (positive energy) ''quark'' fields, starting from a purely fermionic quantum field theory. In the second part of this work, we apply our approach to the Walecka model in 1+1 and 3+1 dimensions. As the Dirac sea caused considerable difficulties in attempts to base nuclear physics on field theoretic models like the Walecka model, mean-field calculations were typically done without the sea. We confront several of these mean-field theory results with our no-sea effective theory approach. The potential of our approach is twofold. While the no-sea effective theory can be utilized to provide new analytical insights in particular parameter regimes, it also sheds new light on more fundamental issues as the explicit emergence of effective, Dirac-sea induced multi-fermion interactions in an effective theory with positive energy states only.

    This special issue consists of papers that are associated with invited lectures, workshop papers and hot topic papers presented at the 20th European Sectional Conference on Atomic and Molecular Physics of Ionized Gases (ESCAMPIG XX). This conference was organized in Novi Sad (Serbia) from 13 to 17 July 2010 by the Institute of Physics of the University of Belgrade. It is important to note that this is not a conference 'proceedings'. Following the initial selection process by the International Scientific Committee, all papers were submitted to the journal by the authors and have been fully peer reviewed to the standard required for publication in Plasma Sources Science and Technology (PSST). The papers are based on presentations given at the conference but are intended to be specialized technical papers covering all or part of the topic presented by the author during the meeting. The ESCAMPIG conference is a regular biennial Europhysics Conference of the European Physical Society focusing on collisional and radiative aspects of atomic and molecular physics in partially ionized gases as well as on plasma-surface interaction. The conference focuses on low-temperature plasma sciences in general and includes the following topics: Atomic and molecular processes in plasmas Transport phenomena, particle velocity distribution function Physical basis of plasma chemistry Plasma surface interaction (boundary layers, sheath, surface processes) Plasma diagnostics Plasma and discharges theory and simulation Self-organization in plasmas, dusty plasmas Upper atmospheric plasmas and space plasmas Low-pressure plasma sources High-pressure plasma sources Plasmas and gas flows Laser-produced plasmas During ESCAMPIG XX special sessions were dedicated to workshops on: Atomic and molecular collision data for plasma modeling, organized by Professors Z Lj Petrovic and N Mason Plasmas in medicine, organized by Dr N Puac and Professor G Fridman.

A more advanced system can be observed in the Gospels and Epistles of Baltramiejus Vilentas (1579, who used acute, grave, angled circumflex, and a tilde-shaped circumflex. The latter was used exclusively in genitive plural ending -ũ, which practice seems to be modeled on the Greek circumflex as in ϑεω̃ν, and Latin nasalization tilde as in deorũ, as well as the humanist Latin distinctive circumflex as in deûm (=-orum.The accent marks used by Rėza in his 1625 Psalter are acute, grave, angled circumflex and dot accent. The inventor of the last of these marks was apparently Rėza himself.The circumflex in Rėza’s Psalter has two different functions, that of signifying the actual word stress and that of distinguishing otherwise homonymous word forms. In the latter case it does not necessarily occur on the actually stressed syllable. Most often the circumflex in this capacity is employed in the genitive plural ending -û (like in Latin -ûm.It seems likely that Rėza did not have a conscious intention of conveying actual syllabic intonations, as is shown by the inconsistencies in his use of accent marks. A special case seems to be the circumflex on ê: here the accent sign appears to have an additional phonetic meaning – that is, Rėza’s ê usually corresponds to the long narrow vowel (which in modern Lithuanian is written ė. This practice was apparently based on intuitive comparison of the humanist Latin orthography (such as legere versus legêre with Lithuanian phonetics.The dot accent is used in the inessive (locative singular ending -ė (-e in modern orthography, sometimes also in the instrumental singular, and rarely in the inessive plural. Like circumflex, the dot accent does not always coincide with the actually stressed syllable. The sign was

  15. Color superconductivity. Phase diagrams and Goldstone bosons in the color-flavor locked phase

    2009-04-29

    The phase diagram of strongly interacting matter is studied with great experimental and theoretical effort and is one of the most fascinating research areas in modern particle physics. It is believed that color superconducting phases, in which quarks form Cooper pairs, appear at very high densities and low temperatures. Such phases could appear in the cores of neutron stars. In this work color superconducting phases are studied within the Nambu-Jona-Lasinio model. First of all, the phase diagram of neutral matter in beta equilibrium is calculated for two different diquark couplings. To this end, we determine the dynamical quark masses self-consistently together with the order parameters of color superconductivity. The interplay between neutrality and quark masses results in an interesting phase structure, in particular for the smaller diquark coupling. In the following, we additionally include a conserved lepton number to map the situation in the first few seconds of the evolution of a protoneutron star when neutrinos are trapped. This has a huge influence on the phase structure and favors the 2SC phase compared to the CFL phase. In the second part of this work we concentrate on the CFL phase which is characterized by a special symmetry breaking pattern. The properties of the resulting nine pseudoscalar Goldstone bosons (GB) are studied by solving the Bethe-Salpeter equation for quark-quark scattering. The GB are the lowest-lying excitations in the CFL phase and therefore play an important role for the thermodynamics of the system. The properties of the GB can also be described by the low-energy effective theory (LEET) for the CFL phase. There the respective low-energy constants are derived for asymptotically high densities where the strong force is weak and can be treated perturbatively. Our aim is the comparison of our results with these predictions, on the one hand to check our model in the weak-coupling limit and on the other hand to derive information about

The G-protein-coupled receptor P2Y12 is a central mediator of platelet activation and aggregation but has also been linked to platelet-independent vascular disease. Ticagrelor is an oral P2Y12 antagonist that is used as a standard treatment in patients after acute myocardial infarction. However, the effects of ticagrelor on advanced atherosclerosis have not been investigated.Materials and methods: Twenty-week-old apolipoprotein-E-deficient mice received standard chow or standard chow supplemented with 0.15% ticagrelor (approximately 270 mg/kg/day for 25 weeks. The lesion area was evaluated in the aortic sinus by Movat’s pentachrome staining and lesion composition, thickness of the fibrous cap, and size of the necrotic core evaluated by morphometry. RAW 264.7 macrophages were serum starved and treated with ticagrelor in vitro for the detection and quantification of apoptosis. In addition, oxLDL uptake in RAW 264.7 macrophages was evaluated.Results: A trend toward the reduction of total lesion size was detected. However, data did not reach the levels of significance (control, n=11, 565,881 µm2 [interquartile range {IQR} 454,778–603,925 µm2] versus ticagrelor, n=13, 462,595 µm2 [IQR 379,740–546,037 µm2]; P=0.1.

Beyond the question raised above concerning outreach versus engagement, I find it VERY DIFFICULT to find the right balance between alerting and stimulating action. On one hand, we need to alert on the reality of the numbers given (and it is hard to reduce our personal emissions by a factor of 4 in France or 10 in the US), the ethical problems they raise (we, in developed countries, are responsible for the majority of past CO2 emissions and we should do the major effort, Ragueneau et al., 2008). And on the other hand, we need to remain optimistic and show that solutions do exist, if we do not want to discourage people to act. There is debate between the ethics of fear (H. Jonas) and the ethics of hope (E. Morin) as best ways to stimulate action and I feel we need to share our experiences on how best navigate between these two lines. So I would be very happy to participate in such a session to discuss the role of scientists in essential issues such as societal debates related to climate change, the frontier between outreach and political engagement, and the attitude needed to convince that there is a problem, that this problem is big and we need to stress it, but that it can be addressed with very positive implications for each of us.

    requirement on being watertight, which also affects the design of the concrete plug. In the spent fuel repository, low-pH concrete should be used instead of conventional concrete. The reason for this is to the largest extent to reduce the negative effect that basic materials could have on the function of the bentonite clay. For this purpose, a new low-pH concrete recipe has been developed and this changes the conditions for using reinforcement, cooling and grouting compared to the use of conventional concrete. The report shows the possibilities to use an unreinforced plug made of low-pH concrete as a resistance in the deposition tunnels. Today, some parameters are unknown and some data may be classified as uncertain, primarily regarding the long-term properties of the low-pH concrete material and the bentonite clay. It will take several years until all questions can be answered and a full-scale test is vital to validate the assumptions and the performed numerical simulations. The report should therefore be considered based on that data and conclusions will be studied further and be experimentally verified under realistic and controlled conditions.

Tais questionamentos demandam uma inversão do agir humano, baseado no Princípio Responsabilidade, no que tange à necessidade de conservação da natureza para promover a garantia de sua existência futura. Dentre as principais formas de se aplicar tal responsabilidade está a atuação do Estado, através do direito em face da responsabilidade de criar as primeiras bases de aplicação de políticas públicas presentes que demandem projeções futuras e também que tenham como pré-condição os fundamentos de uma ética da responsabilidade. O Brasil, detentor de uma das maiores fontes de biodiversidade do mundo, possui em sua Carta Magna premissas que têm por escopo unir a proteção ambiental à qualidade de vida de presentes e futuras gerações, considerando, inclusive, que tal norma tenha a natureza de direito fundamental, o que corrobora para a necessidade de aplicação de uma Ética da Responsabilidade, no sentido de salvaguardar prudentemente os elementos presentes na natureza e consequentemente a existência de continuidade da espécie humana neste universo. Para tanto, objetiva-se no presente trabalho, bibliográfico e documental, estabelecer uma relação ético-jurídica entre um meio ambiente devidamente equilibrado e a qualidade de vida dos indivíduos presentes no território brasileiro, com base no contexto jurídico brasileiro atual, especificamente no que diz respeito à defesa do meio ambiente brasileiro presente no texto da Constituição Federal do Brasil, o que nos remete aos interesses intergeracionais e intrageracionais de proteção humana.

  3. Reconstruction of 3d grain boundaries from rock thin sections, using polarised light

    2016-04-01

    Grain boundaries affect the physical and chemical properties of polycrystalline materials significantly by initiating reactions and collecting impurities (Birchenall, 1959), and play an essential role in recrystallization (Doherty et al. 1997). In particular, the shape and crystallographic orientation of grain boundaries reveal the deformation and annealing history of rocks (Kruhl and Peternell 2002, Kuntcheva et al. 2006). However, there is a lack of non-destructive and easy-to-use computer supported methods to determine grain boundary geometries in 3D. The only available instrument using optical light to measure grain boundary angles is still the polarising microscope with attached universal stage; operated manually and time-consuming in use. Here we present a new approach to determine 3d grain boundary orientations from 2D rock thin sections. The data is recorded by using an automatic fabric analyser microscope (Peternell et al., 2010). Due to its unique arrangement of 9 light directions the highest birefringence colour due to each light direction and crystal orientation (retardation) can be determined at each pixel in the field of view. Retardation profiles across grain boundaries enable the calculation of grain boundary angle and direction. The data for all positions separating the grains are combined and further processed. In combination with the lateral position of the grain boundary, acquired using the FAME software (Hammes and Peternell, in review), the data is used to reconstruct a 3d grain boundary model. The processing of data is almost fully automatic by using MATLAB®. Only minor manual input is required. The applicability was demonstrated on quartzite samples, but the method is not solely restricted on quartz grains and other birefringent polycrystalline materials could be used instead.

    The area of this report includes 436 square miles centered about the District of Columbia. The area contains parts of two distinctly different physiographic provinces-the Piedmont and the Coastal Plain. The Fall Line, which separates the Piedmont province on the west from the Coastal Plain Province on the east, bisects the area diagonally from northeast to southwest. Northwest of the Fall Line, deeply weathered igneous and metamorphic rocks are exposed ; to the southeast, these rocks are covered by Coastal Plain sediments; the nonconformity between crystalline rock and sediments dips southeast at an average rate of about 125 feet per mile. The rocks of the Piedmont include: (1) schist, phyllite, and quartzite of the Wissahickon Formation; (2) altered mafic rocks such as greenstone and serpentine; (3) the Laurel Gneiss of Chapman, 1942, and the Sykesville Formation of Jonas, 1928--both probably derived from the Wissahickon ; and (4) later granitic intrusive rocks. Lying upon this basement of hard rocks east of the Fall Line are the generally unconsolidated sediments of the Coastal Plain, which include gravel, sand, and clay, ranging in age from Cretaceous to Recent. These sediments measure only a few inches at their western extremity but thicken to 1,800 feet at the southeast corner of the mapped area. Owing to the great diversity in the geology of the two provinces, the waterbearing characteristics of the rocks also vary greatly. In the Piedmont, ground water occurs under unconfined or water-table conditions in openings and fissures in the hard rocks or in the residual weathered blanket that overlies them. In the Coastal Plain, the shallow wells tap unconfined water, but beneath the upper clay layers the water is contained in the sand and gravel under artesian pressure and must be recovered by deep drilled wells. Wells are of three types--drilled, bored, and dug. Drilled wells furnish a permanent water supply and are the least subject to pollution when properly

    information [7] and in Stockholm he had, again, very successful postdocs such as Ulf Leonhardt. Finally, in 2005, Stig Stenholm retired, although he is still active, writing papers, taking part in conferences and making research visits. We honoured his 70th birthday at the CEWQO2009 conference, and hope that the future provides us with further opportunities for such events. Looking at the obituary of Dirk ter Haar, I see that his style with students reminds me of Stig's approach. In my opinion, Stig expects independence and initiative from a student, giving perhaps a broad topic in which the student is expected to find his or her own way, whilst working perhaps with a postdoc. Juha Javanainen has talked about the 'sink or swim' style (not referring to Stig, though). There is a famous series of children's books about Moomin trolls by Tove Jansson (another Swedish-speaking Finn like Stig). In one of them, the Moomin find in early spring a small flower in a patch of land uncovered by snow, pushing its way up. One of them wants to cover it against frost during the night, but another says 'Don't, it'll fare better later if it has some difficulties at first'. At CEWQO2009 Stig gave the full list of his finished PhD students: Rainer Salomaa (1973), Temba Dlodlo (1980), Juha Javanainen (1980), Markus Lindberg (1985), Matti Kaivola (1985), Birger Ståhlberg (1985), Kalle-Antti Suominen (1992), Mackillo Kira (1995), Päivi Törmä (1996), Asta Paloviita (1997), Patrik Öhberg (1998), Martti Havukainen (1999), Erika Andersson (2000), Pawel Piwnicki (2001), Åsa Larson (2001), Markku Jääskeläinen (2003), and Jonas Larson (2005). One should also mention Erkki Kyrölä, who eventually graduated at Rochester and Olli Serimaa, who never graduated but published some important early-stage laser cooling work. As a final note I must mention a passion that Stig and I share, namely books. I have nearly 400 professional physics and mathematics books, but I am certain that the size of Stig
