    Ziman, John

    Mr. Vice-Chancellor Only connect! That is the theme that runs through the life and work of Abdus Salam. He has followed the teaching of Islam and has dedicated his life to the principle of unity — the unity of Nature and the unity of Mankind. As a natural philosopher he has seen that the various interactions of the elementary particles must be no more than diverse aspects of a single primary force. As a political and moral leader he has demonstrated that the various interactions of nations and cultures are no obstacle to the brotherhood of Man in science…

    The "International Workshop on Theoretical Plasma Physics: Modern Plasma Science was held at the Abdus Salam International Centre for Theoretical Physics (Abdus Salam ICTP), Trieste, Italy during the period 5 16 July 2004. The workshop was organized by P K Shukla, R Bingham, S M Mahajan, J T Mendonça, L Stenflo, and others. The workshop enters into a series of previous biennial activities that we have held at the Abdus Salam ICTP since 1989. The scientific program of the workshop was split into two parts. In the first week, most of the lectures dealt with problems concerning astrophysical plasmas, while in the second week, diversity was introduced in order to address the important role of plasma physics in modern areas of science and technology. Here, attention was focused on cross-disciplinary topics including Schrödinger-like models, which are common in plasma physics, nonlinear optics, quantum engineering (Bose-Einstein condensates), and nonlinear fluid mechanics, as well as emerging topics in fundamental theoretical and computational plasma physics, space and dusty plasma physics, laser-plasma interactions, etc. The workshop was attended by approximately hundred-twenty participants from the developing countries, Europe, USA, and Japan. A large number of participants were young researchers from both the developing and industrial countries, as the directors of the workshop tried to keep a good balance in inviting senior and younger generations of theoretical, computational and experimental plasma physicists to our Trieste activities. In the first week, there were extensive discussions on the physics of electromagnetic wave emissions from pulsar magnetospheres, relativistic magnetohydrodynamics of astrophysical objects, different scale sizes turbulence and structures in astrophysics. The scientific program of the second week included five review talks (60 minutes) and about thirty invited topical lectures (30 minutes). In addition, during the two weeks, there

    This book presents a biography of Abdus Salam, the first Muslim to win a Nobel Prize for Science (Physics 1979), who was nevertheless excommunicated and branded as a heretic in his own country. His achievements are often overlooked, even besmirched. Realizing that the whole world had to be his stage, he pioneered the International Centre for Theoretical Physics in Trieste, a vital focus of Third World science which remains as his monument. A staunch Muslim, he was ashamed of thedecline of science in the heritage of Islam, and struggled doggedly to restore it to its former glory. Undermined by

  5. The Abdus Salam dream

    1994-01-01

    The frontiers in Physics are dominated by the contributors of Abdus Salam in terms of new basic ideas. These contributions have their most fascinating synthesis in the following question: does the Superworld exist? The only possible answer to this question is to review the most basic results of Super-Grand unification. We focus the attention on two specific models and their predictions. These two models represent an example of a direct comparison between a traditional unified-theory and a string-inspired approach to the solution of the many open problems of the Standard Model. Viable models must satisfy all available experimental constraints and be as simple as theoretically possible. The two well defined supergravity models, SU(5) and SU(5) x U(1), can be described in terms of only a few parameters (five and three respectively) instead of the more than twenty needed in the MSSM model, i.e., the Minimal Supersymmetric extension of the Standard Model. A case of special interest is the strict no-scale SU(5) x U(1) supergravity where all predictions depend on only one parameter (plus the top-quark mass). A general consequence of these analyses is that the Superworld can be at the verge of discovery, lurking around the corner at present and near future facilities. This is in fact the projection of Salam's dream in the real axis. (author). 45 refs, 10 figs, 1 tab

    In honor of one of the most prolific and exciting scientists of the second half of the last century, a memorial meeting was organized by the Institute of Advanced Studies at Nanyang Technological University for Professor Abdus Salam's 90th Birthday in January 2016. Salam believed that "scientific thought is the common heritage of all mankind" and that the developing world should play its part, not merely by importing technology but by being the arbiter of its own scientific destiny. That belief saw him rise from humble beginnings in a village in Pakistan to become one of the world's most original and influential particle physicists, culminating in the 1979 Nobel Prize (shared with Glashow and Weinberg) for contributions to electroweak unification, which forms an integral part of the Standard Model. The book collected the papers presented at this memorable event which saw many distinguished scientists participating as speakers to reflect on Prof Salam's great passion for the science and achievements.

    The Abdus Salam International Centre for Theoretical Physics stems the brain drain of physicists from developing nations at a time of new scientific challenges. Abdus Salam, a Nobel Prize-winning Pakistani physicist, recognized that improving science locally would not be enough to stem the flight of fledgling scientists from developing countries. International mechanisms would be needed to allow scientists - especially those returning home after training abroad - to stay connected with the world, to refresh their knowledge periodically, and to engage in international research collaborations. The time was right for the conception of an international centre for theoretical physics. In 1964 under the aegis of the IAEA, the Abdus Salam International Centre for Theoretical Physics (ICTP) was intended to be not just another international research institute. The intention was a model organization designed to promote training and research in the physical and mathematical sciences in developing countries; serve as a forum for scientists from all over the world; and operate as a first-class scientific institution. All three goals reflect the desire of its founding director, Abdus Salam, to confront the issues of isolation and brain drain that have continually dimmed the prospects for scientific excellence across the developing world. Today ICTP each year hosts some 6000 scientists in its facilities in Trieste, Italy, while maintaining strong and enduring links with scientific communities in more than 170 countries. Closer to home, it has forged cooperative relationship with many Italian scientific institutions. Through its efforts, the Centre has built a worldwide family of loyal alumni, tens of thousands of associates, lecturers, and students, many of whom are now internationally recognized scientists, university leaders, research-council presidents, and leading statesmen in their own countries

    Abdus Salam was one of the most prolific and exciting scientists of the second half of the last century. From humble beginnings in a village in Pakistan, he rose to become one of the world's most original and influential particle physicists. He shared the 1979 Nobel Prize with Glashow and Weinberg for contributions to electroweak unification, which forms an integral part of the Standard Model. He was the first Pakistani Nobel Laureate and the second only Muslim after Anwar Sadat. After gaining his doctorate in Cambridge, he moved to Imperial College in 1957 where he founded the very successful Theoretical High Energy Physics Group. He remained there as Professor of Physics until his death in 1996.

    Abdus Salam was a great man in more than one dimension. The conception and building of the ICTP system required much more than the intelligence of a great scientist. I will stress those other facets that made him such a unique personality: the optimism that coloured his views about men and women, his love for his people and his commitment to the less favoured peoples of the world and a crucial ingredient, his deep and complex sense of ethical values that pushed him towards engagement in the political reality. Endowed with a formidable power of persuasion and a healthy lack of respect for norms or rules that are not based on justice he made a big difference on many of us and will remain as an icon for future generations. I will also describe the final touches that Salam’s collaborators and successors had to add to keep his heritage flourishing.

    This ICTP Internal Report contains the list of papers presented, activity report and the write up of a number of presentations delivered during the International Reference Ionosphere (IRI) Task Force Activity 2001 which took place at the Abdus Salam ICTP during May 2001, particularly centred in the week from 21-25 May. The 2001 Task Force Activity is the eighth successful encounter of specialists organized by the URSI-Cospar IRI Working Group and the Aeronomy and Radiopropagation Laboratory of the Abdus Salam International Centre for Theoretical Physics of Trieste, Italy. This project continues the IRI Task Force Activities at the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. The primary focus of this activity was the development of a specification model for ionospheric variability. Such a model is high on the wish list of users of ionospheric models. Climatological models like IRI provide monthly mean values of ionospheric parameters. Understandably a satellite designer or operator needs to know not only the monthly average conditions but also the expected deviations from these mean values. The main discussions and presentations took place during the week 21-25 May. The format was similar to last year's activity with presentations and round-table discussions in the morning and follow-on work in small subgroups in front of computer terminals in the afternoon. This Proceedings contains also four papers of the previous IRI Task Force Activity which were omitted

    The Physics of Weather and Climate Section at the Abdus Salam International Centre for Theoretical Physics, established in 1998, is currently performing research on different aspects of climate variability, dealing with both natural and anthropogenic aspects of climate changes. In addition to performing diagnostic work on multi-decadal observational datasets and climate simulations carried out in major research centres, the PWC section has been developing its own climate modeling capability, which is focused on three main areas: a) modeling of regional climate change; b) seasonal forecasting at global and regional scale; c) development of simplified models of the general circulation. On topic a), research on different aspects of anthropogenic climate change is being carried out using the Regional Climate (RegCM) developed by Giorgi and collaborators at the National Centre for Atmospheric Research. Time-slice experiments with a high-resolution atmospheric GCM, comparing current climate conditions with future climate scenarios in selected decades, are also planned for the near future. On topic b), a strategy based on ensembles of high-resolution simulations with atmospheric GCM's, using sea surface temperature anomalies predicted by lower-resolution coupled models from other institutions, is currently under experimentation. A one-way nesting of RegCM into the GCM simulations will also be tested. On item c), a 5-layer atmospheric GCM with simplified physical parameterizations has been developed. This model has a very small computational cost compared with state-of-the-art GCMs, and is suitable for studies of natural climate variability on inter-decadal and intercentennial time scales. It is planned to couple this model to simplified ocean models of different complexity, from a simple, static mixed layer model, to simplified models of the tropical Pacific circulation suited to the simulation of the El Nino phenomenon.

    A quaternionic Weinberg-Salam theory is formulated based on the assumption that fermio ns and Higgs mesons are defined over quaternions. The new formalism, reproducing the left-right symmetric SU(2)sub(L) x SU(2)sub(R) x U(1) Weinberg-Salam theory at the phenomenological level, offers an algebraic explanation for replication of quarks and leptons in flavor doublets, and correlates the spontaneous symmetry breakdown to U(1)sub(em) with the existence of Fock space for gauge singlets but not for quaternionic states. In particular, the quaternionic variational principle introduced to canonically quantize the quaternionic fields in conformity with the gauge-singlet Fock-space formulation and the spontaneous symmetry breakdown. Physical states must be gauge singlets since they belong to the Fock space. (author)

    Abak, M.

    1980-01-01

    In this paper, an elementary description of unified theories of weak and electromagnetic interactions (Weinberg-Salam model) and their extensions is given. The electromagnetic form factors of the neutrino are discussed and its magnetic moment has been obtained on the basis of the SUsub(2,L) x SUsub(2,R) x U 1 model. Further the matrix element of the photon-photon process important for astrophysics is calculated by the SUsub(2,L) x U 1 model of Weinberg and Salam. Also, some neutral-current consequences for the supernovae are discussed. (author)

    The ICTP was originally part of the Agency. In 1993, administration of the ICTP was transferred to UNESCO. We are still an important contributor to the ICTP budget and we work together in many areas, including training and nuclear knowledge management. This year, for example, our two organisations launched a two-year masters degree course in medical physics, which we developed together. Later today, I look forward to attending the opening of the IAEA X-Ray Fluorescence Beamline at the Elettra laboratory, which has been an IAEA Collaborating Centre since 2005. This important joint project will help to give research groups from developing countries better access to synchrotron radiation technology, which has important applications in human health, food and agriculture and other areas

  10. Modeling commodity salam contract between two parties for discrete and continuous time series

    2017-08-01

    In order for Islamic finance to remain competitive as the conventional, there needs a new development of Islamic compliance product such as Islamic derivative that can be used to manage the risk. However, under syariah principles and regulations, all financial instruments must not be conflicting with five syariah elements which are riba (interest paid), rishwah (corruption), gharar (uncertainty or unnecessary risk), maysir (speculation or gambling) and jahl (taking advantage of the counterparty's ignorance). This study has proposed a traditional Islamic contract namely salam that can be built as an Islamic derivative product. Although a lot of studies has been done on discussing and proposing the implementation of salam contract as the Islamic product however they are more into qualitative and law issues. Since there is lack of quantitative study of salam contract being developed, this study introduces mathematical models that can value the appropriate salam price for a commodity salam contract between two parties. In modeling the commodity salam contract, this study has modified the existing conventional derivative model and come out with some adjustments to comply with syariah rules and regulations. The cost of carry model has been chosen as the foundation to develop the commodity salam model between two parties for discrete and continuous time series. However, the conventional time value of money results from the concept of interest that is prohibited in Islam. Therefore, this study has adopted the idea of Islamic time value of money which is known as the positive time preference, in modeling the commodity salam contract between two parties for discrete and continuous time series.

  15. Irreducible gauge theory of a consolidated Salam-Weinberg model

    International Nuclear Information System (INIS)

    Ne'eman, Y.

    1979-01-01

    The Salam-Weinberg model is derived by gauging an internal simple supergroup SU(2/1). The theory uniquely assigns the correct SU(2)sub(L) X U(1) eigenvalues for all leptons, fixes thetasub(W) = 30 0 , generates the W +- sub(sigma), Z 0 sub(sigma) and Asub(sigma) together with the Higgs-Goldstone Isub(L) = 1/2 scalar multiplets as gauge fields, and imposes the standard spontaneous breakdown of SU(2)sub(L) X U(1). The masses of intermediate bosons and fermions are directly generated by SU(2/1) universality, which also fixes the Higgs field coupling. (Auth.)

  16. Operator regularization in the Weinberg-Salam model

    International Nuclear Information System (INIS)

    Chowdhury, A.M.; McKeon, D.G.C.

    1987-01-01

    The technique of operator regularization is applied to the Weinberg-Salam model. By directly regulating operators that arise in the course of evaluating path integrals in the background-field formalism, we preserve all symmetries of the theory. An expansion due to Schwinger is employed to compute amplitudes perturbatively, thereby avoiding Feynman diagrams. No explicitly divergent quantities arise in this approach. The general features of the method are outlined with particular attention paid to the problem of simultaneously regulating functions of an operator A and inverse functions upon which A itself depends. Specific application is made to computation of the one-loop contribution to the muon-photon vertex in the Weinberg-Salam model in the limit of zero momentum transfer to the photon

    1982-01-01

    We have studied the one-loop effects in the Weinberg-Salam theory in the natural renormalization scheme which we have generalized to the case of an arbitrary unitary mixing of the fermion fields. We have discussed in detail the problems which are connected with carrying out the renormalization program in the Weinberg-Salam theory. We have calculated the masses of the W and Z bosons. We present a description of the finite renormalizations which relate to each other the three definitions of the Weinberg parameter sin 2 theta/sub W/

  1. Topology in the Weinberg-Salam theory

    International Nuclear Information System (INIS)

    Manton, N.S.

    1983-01-01

    We show that the configuration space of the classical, bosonic Weinberg-Salam theory has a noncontractible loop. This probably implies that there is an unstable, static, finite-energy solution of the field equations. Its energy is the height of the barrier for tunneling between ''topologically distinct'' vacuums. We establish an upper bound on this energy of order 10 TeV

  2. Reformulation of the Salam-Weinberg unified theory of weak and electromagnetic interactions

    International Nuclear Information System (INIS)

    Khan, I.

    1981-01-01

    It is shown that the various fields (gauge potentials, etc.) in the Salam-Weinberg unified theory can be redefined such that i) the redefined fields are invariant under the SU 2 gauge transformations, ii) the original Lagrangian can be expressed entirely in terms of the redefined fields. The reformulated version of the Salam-Weinberg model has two first-class and six second-class constraints in contrast with the original version which has eight first-class constraints. This has the consequence that in the reformulated version the SU 2 x U 1 symmetry, which seems to be reduced to U 1 at the Lagrangian stage, is recovered for the algebra of charges when their Dirac brackets are identified with the commutators. It is suggested that the Salam-Weinberg model may be looked upon as an example of confined dichromatism. (author)

  3. Electron-electron scattering in the Weinberg-Salam theory

    International Nuclear Information System (INIS)

    Hirashima, Hideharu

    1988-01-01

    The Weinberg theory is generally believed to have been established in recent years. At distances smaller than 10 -16 cm, the strength of weak interactions becomes almost equal to that of the electromagnetic interactions. The grand unified theories proposed so far are based on the idea that the coupling constants for the Abelian U(1) field, the non-Abelian SU(2) field and the non-Abelian SU(3) color field depend on momentum transfer, or distance. At distances smaller than 10 -29 cm, weak electromagnetic and strong interactions are assumed to become almost the same strength. The question here is whether nature has no new features in the vast range from 10 -16 cm (10 2 GeV) to 10 -29 cm (10 15 GeV) and whether the substructure of quark or lepton can be expected to be revealed at the next accelerator energy region. The Weinberger-Salam theory may lose its validity even in near future experiments. In any case, it must be overhauled from various aspects. From this point of view, by using the Weinberger-Salam theory, calculation of the differential cross section for elastic electron-electron scattering is re-examined to make clear the difference with the results of QED. In addition, as an example of experiments which could investigate the Weinberger-Salam theory more in detail, a short account is given of the elastic scattering of polarized electrons from a polarized electron target.

  4. Reformulation od spontaneous symmetry breaking and the Weinberg-Salam model

    International Nuclear Information System (INIS)

    Rawat, A.S.; Rawat, S.; Negi, O.P.S.

    1999-01-01

    Spontaneous symmetry breaking and the Weinberg-Salam model have been reformulated in terms of quaternion-valued field variables. The quaternion-valued scalar Lagrangian reduces to four different field equations associated with the scalar quartet of a quaternion field φ φ 0 +e 1φ1 +e 2φ2 +e 3φ3 . It has been shown that the quaternion gauge group SO(4) is spontaneously broken to two gauge groups of SU(2) non Abelian gauge fields. The Weinberg-Salam model of electroweak interaction has been extensively studied to enlarge the gauge group structure SU(2) L xSU(2) R xU(1)

  6. Masses in the Weinberg-Salam model

    International Nuclear Information System (INIS)

    Flores, F.A.

    1984-01-01

    This thesis is a detailed discussion of the currently existing limits on the masses of Higgs scalars and fermions in the Weinberg-Salam model. The spontaneous breaking of the gauge symmetry of the model generates arbitrary masses for Higgs scalars and fermions, which for the known fermions have to be set to their experimentally known values. In this thesis, the authors discuss in detail both the theoretical and experimental constraints on these otherwise arbitrary masses

  7. Salam-Weinberg symmetry breaking with superheavy Higgs particles

    International Nuclear Information System (INIS)

    Misra, S.P.

    1986-09-01

    We discuss here the possibility of the breaking of the Salam-Weinberg symmetry by Higgs particles which are superheavy. The symmetry-breaking is associated with a nonzero vacuum expectation value of fermion condensates. This mechanism, if operative in nature, will imply the absence of Higgs particles at the weak scale. (author)

    Family symmetries and grand unified symmetries can bring more structure in the mass sector of the standard model and explain the patterns in the quarks’ and leptons’ masses and mixing. We discuss in particular a model with a Pati-Salam × S4 symmetry. This model can explain the observed neutrino

    International Nuclear Information System (INIS)

    Nichols, A.L.; Tuli, J.K.

    2008-01-01

    The International Network of Nuclear Structure and Decay Data (NSDD) experts consists of a number of evaluation groups and data service centres in several countries that appreciate the merits of working together to maintain and ensure the quality and comprehensive content of the ENSDF database (Evaluated Nuclear Structure Data File). Biennial meetings of the network are held under the auspices of the International Atomic Energy Agency (IAEA) to assign evaluation responsibilities, monitor progress, discuss improvements and emerging difficulties, and agree on actions to be undertaken by individual members. The evaluated data and bibliographic details are made available to users via various media, such as the journals Nuclear Physics A and Nuclear Data Sheets, the World Wide Web, on CD-Rom, wall charts of the nuclides and Nuclear Wallet Cards. While the ENSDF master database is maintained by the US National Nuclear Data Center at the Brookhaven National Laboratory, these data are also available from other nuclear data centres including the IAEA Nuclear Data Section. The Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy, in cooperation with the IAEA, organizes workshops on NSDD at regular intervals. The primary aims of these particular workshops are to provide hands-on training in the data evaluation processes, and to encourage new experts to participate in NSDD activities. The technical contents of these NSDD workshops are described, along with the rationale for the inclusion of various topics. (authors)

  10. Model for extended Pati-Salam gauge symmetry

    Foot, R.; Lew, H.; Volkas, R.R.

    1990-11-01

    The possibility of constructing non-minimal models of the Pati-Salam type is investigated. The most interesting examples are found to have an SU(6) x SU(2) L x SU(2) R guage invariance. Two interesting symmetry breaking patterns are analysed: one leading to the theory of SU(5) colour at an intermediate scale, the other to the quark-lepton symmetric model. 15 refs

    The theory of spontaneous CP-violation proposed by Lee is applied to the standard Weinberg-Salam model with four quark flavours. The magnitude of the epsilon-parameters is determined and the neutrons dipole moment is estimated to be ( -23 cm. The epsilon'-parameter and possible extension to a model with more quarks are discussed

  12. On a derivation of the Salam-Weinberg model

    Squires, E.J.

    1979-01-01

    It is shown how the graded Lie-algebra structure of a recent derivation of the Salam-Weinberg model might arise from the form of allowed transformations on the lepton lagrangian in a 6-dimensional space. The possibility that the model might allow two identically coupled leptonic sectors, and others in which the chiralites are reversed, are discussed. (Auth.)

    Alavi, S.A.; Sarbishaei, M.; Mokhtari, A.

    2000-01-01

    We study the q-deformation of the gauge part of the Weinberg-Salam model and show that the q-deformed theory involves new interactions. We then obtain q-deformed Maxwell equations from which magnetic monopoles appear naturally. (author)

  15. Weak interaction potentials of nucleons in the Weinberg-Salam model

    International Nuclear Information System (INIS)

    Lobov, G.A.

    1979-01-01

    Weak interaction potentials of nucleons due to the nonet vector meson exchange are obtained in the Weinberg-Salam model using the vector-meson dominance. Contribution from the hadronic neutral currents to the weak interaction potential due to the charged pion exchange is obtained. The isotopic structure of the obtained potentials, that is unambiguous in the Weinberg-Salam model, is investigated. Enhancement of the nucleon weak interaction in nuclei resulting from the hadronic neutral currents is discussed. A nuclear one-particle weak interaction potential is presented that is a result of averaging of the two-particle potential over the states of the nuclear core. An approach to the nucleon weak interaction based on the quark model, is discussed. Effects of the nucleon weak interaction in the radiative capture of a thermal neutron by a proton, are considered

  16. A new six-dimensional approach to the Weinberg-Salam model

    Manton, N.S.

    1979-01-01

    The bosonic sector of the Weinberg-Salam model is derived from a 6-dimensional Yang-Mills theory by imposing rotational symmetry in the extra, compact dimensions. The Weinberg angle and the mass of the Higgs particle are predicted. (Auth.)

  17. The variational approach to the Glashow-Weinberg-Salam model

    International Nuclear Information System (INIS)

    Manka, R.; Sladkowski, J.

    1987-01-01

    The variational approach to the Glashow-Weinberg-Salam model, based on canonical quantization, is presented. It is shown that taking into consideration the Becchi-Rouet-Stora symmetry leads to the correct, temperature-dependent, effective potential. This generalization of the Weinberg-Coleman potential leads to a phase transition of the first kind

    1998-03-01

    The author describes his first in 1958 at the unification of electromagnetic and weak interactions and his prediction in the same paper of the neutral Z 0 boson which would be the intermediate quantum exchanged in an eventual electron-neutron weak interaction (as muonic neutrinos were not known at that time). In annex he transcribes copies of letters from Steven Weinberg, Abdus Salam and Bruno Pontecorvo and comments by C.N. Yang and J. Tiomno. (author)

  19. Measurement of the transverse momentum differential cross-section for Z boson decays to muon anti-muon events in proton anti-proton collisions at center-of-mass energy = 1.8-TeV

    Energy Technology Data Exchange (ETDEWEB)

    Krasberg, Mark T. [Univ. of Michigan, Ann Arbor, MI (United States)

    2003-01-01

    In 1961 Sheldon Lee Glashow, while working on electroweak unification gauge theory, developed a model in which he introduced a massive neutral intermediate vector boson, call Z [1], [2], [3]. By 1967 Steven Weinberg and Abdus Salam had independently solved the theoretical problems with this model and developed their own self-consistent theory. In this thesis the Z gauge boson production rate at CDF as a function of the Z transverse momentum is studied in the dimuon channel.

    In the framework of a very fruitful, stimulating and still ongoing collaboration between the National Institute for Earth Physics - Bucharest, the Department of Earth Sciences - University of Trieste and The Abdus Salam International Center for Theoretical Physics - SAND Group, several innovative steps forwards have been made in the assessment of the seismic hazard generated by Vrancea seismicity. The limits of currently applied probabilistic approaches are partly overcome by the introduction of hazard scenarios based on the deterministic, realistic modeling of ground motion. The ongoing co-operation represents a fundamental contribution to the reliable assessment of seismic hazard, and has been recently enriched by the participation of Bulgarian scientists, who are facing, in the urban settlements close to the Romanian border, a seismic hazard similar to the one in Bucharest.

    Simulation experts win Dirac Medal Condensed-matter theorists Roberto Car of Princeton University in the US and Michele Parrinello of the Swiss Federal Institute of Technology (ETH Zurich) have won the 2009 Dirac Medal for their work on numerical-simulation techniques. The pair began developing new methods of modelling molecular dynamics in the mid-1980s, using elements of density functional theory and Newtonian molecular dynamics to calculate the mechanical motion of atoms and molecules in real time. Now known as the Car-Parrinello method, their technique has become a standard tool in computational physics and chemistry. The award, which is announced each year on 8August, Dirac's birthday, carries a cash prize of 5000 and is sponsored by the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy.

    1965-01-01

    Full text: The first scientific research and educational institution to be set up on a completely international basis was officially inaugurated in Trieste on 5 October 1964 by the Director General of IAEA, Dr. Sigvard Eklund, when he opened the first seminar of the International Centre for Theoretical Physics. As evidence of the international nature of the institution he noted that the scientists who would work and teach there during the first year represented sixteen different countries. By the end of 1964, the Centre building was nearing completion and three of the five floors were occupied. A successful symposium had been held on the subject of plasma physics, and a score of professors and fellows were at work, from Bulgaria, Czechoslovakia, Greece, India, Japan, Jordan, the Netherlands, Norway, Pakistan, Poland, the United Kingdom, and the United States. A dozen scientific papers had been issued as preprints. The main purpose of the Centre is to foster the advancement of theoretical physics through training and research; at first the chief subject will be high-energy and elementary particle physics. Plasma physics, low energy physics and solid-state physics will also be dealt with. Special attention is paid to the needs of the developing countries. Of the 25 fellows selected for the academic year 1964-65, more than half are from South America, Africa and Asia. In conjunction with the Research Centre, there is an Advanced School for theoretical Physics to provide graduate training for fellows who need such preparation before they embark upon research. The Centre works under the guidance of a Scientific Council comprising the president, Prof. M. Sandoval-Vallarta (Nuclear Energy Commission of Mexico); Prof. A. Abragam (Saclay, France); Prof. R. Oppenheimer (Institute for Advanced Study, Princeton, USA); Dr. V. Soloviev (Dubna, USSR); Prof V.F. Weiskopf (Director General, CERN) ; Prof Abdus Salam (Imperial College, London) ; Prof. P.

    The IAEA distributed the k 0I AEA software package program to several laboratories. The Laboratory for Neutron Activation Analysis, at CDTN/CNEN (Centro de Desenvolvimento da Tecnologia Nuclear/Comissao Nacional de Energia Nuclear), Belo Horizonte, Brazil, acquired the k 0I AEA software package during the Workshop on Nuclear Data for Activation Analysis, 2005, held at the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy. This paper is about the validation procedure carried out at the local laboratory aiming at the validation of the k 0I AEA software package. After the software was set up according to the guidelines, the procedure followed at CDTN/CNEN to validate the k 0I AEA software was to analyse several reference materials. The overall results pointed out that the k 0I AEA software is working properly. (author)

    1980-01-01

    An alternative proof of ultraviolet divergence cancellation (at the one-loop level) in certain ratios of renormalized coupling constants in the Weinberg-Salam model is suggested. Working in the unitary gauge, we use a simple coordinate-space method for manipulating Feynman integrals proposed by Kummer and Lane. In a particular example it is shown that this method provides an extremely useful tool for solving the problem. (author)

    It is shown that spontaneous symmetry breaking is predominantly driven by scalar loops in the standard Salam-Weinberg-Glashow model if lambda approx.=0(e 2 ). The Higgs mass is predicted to be 0(64 GeV), which is considerably higher than the Coleman Weinberg prediction. (author)

  12. The Weinberg-Salam model and early cosmology

    Steinhardt, P.J.

    1981-01-01

    The consequences for cosmology of the phase transition in which SU(2) x U(1) symmetry is broken in the Weinberg-Salam model are discussed. The qualitative arguments concerning the effect of the phase transition on the baryon-to-entropy ratio that were recently posed by Witten for the case of a Coleman-Weinberg light Higgs boson are confirmed through exact numerical computations, but some quantitative disagreement is found. The computations are extended to the case in which the light Higgs boson is not of the Coleman-Weinberg type and the nature of the phase transition is discussed. Other cosmological effects are considered. (orig.)

  13. P-odd asymmetries in the deep inelastic lepton-nucleon scattering as a test of the Weinberg-Salam theory

    International Nuclear Information System (INIS)

    Bilenkij, S.M.; Motz, G.

    1979-01-01

    The P-Odd asymmetries in the processes l +- + N → l +- + X with longitudinally polarized leptons are discussed in the framework of the Weinberg-Salam model. For the case of isoscalar targets the P-Odd asymmetries Asub(+-) are shown to be related to the cross sections of the process νsub(μ)(antiνsub(μ)) + N → μ +- + X using only the transformation properties of the neutral current. The measurement of both Asub(-) and Asub(+) would permit one to test the Weinberg-Salam model. (author)

  14. B-decay anomalies in Pati-Salam SU(4)

    Science.gov (United States)

    Barbieri, Riccardo; Tesi, Andrea

    2018-03-01

    Attempts to incorporate in a coherent picture the B-decay anomalies presumably observed in b→ c and b→ s semi-leptonic decays have to face the absence of signals in other related experiments, both at low and at high energies. By extending and making more precise the content of Barbieri et al. (Eur Phys J C 77(1):8, 2017), we describe one such attempt based on the Pati-Salam SU(4) group, that unifies colour and the B- L charge, in the context of a new strongly interacting sector, equally responsible for producing a pseudo-Goldstone Higgs boson.

  15. Pati-Salam version of subcritical hybrid inflation

    Science.gov (United States)

    Bryant, B. Charles; Raby, Stuart

    2016-05-01

    In this paper we present a model of subcritical hybrid inflation with a Pati-Salam (PS) symmetry group. Both the inflaton and waterfall fields contribute to the necessary e -foldings of inflation, while only the waterfall field spontaneously breaks PS hence monopoles produced during inflation are diluted during the inflationary epoch. The model is able to produce a tensor-to-scalar ratio, r model also incorporates a Z4R symmetry which can resolve the μ problem and suppress dimension 5 operators for proton decay, leaving over an exact R parity. Finally the model allows for a complete three-family extension with a D4 family symmetry which reproduces low energy precision electroweak and LHC data.

  16. Skyrmion solutions to the Weinberg-Salam model

    International Nuclear Information System (INIS)

    Eilam, G.; Klabucar, D.; Stern, A.

    1986-01-01

    We find a spherically symmetric solution to the gauged SU(2)/sub L/ x SU(2)/sub R/ chiral model. It corresponds to a new classical solution to the Weinberg-Salam model in the limit of infinite self-coupling and sin 2 theta/sub W/ = 0. It has an energy of 11.6 TeV and is classically unstable under small perturbations of the fields. Quantum corrections may stabilize the solution via the introduction of higher-order terms in the effective action. We then investigate the solutions when a particular choice of a correction, the Skyrme term, is added to the Lagrangian. The energies of the (presumably) classically stable solutions are in the terraelectrovolt region

  17. SU(2) x U(1) x U'(1) models which are slightly different from the Weinberg-Salam model

    Gao, C.; Wu, D.

    1981-01-01

    We discuss SU(2) x U(1) x U'(1) models by a uniform formula which is convenient for their comparison with the standard Weinberg-Salam model. As examples, we give three interesting models which are based on different grand unification models. In one model, U'(1) does not contribute to the electromagnetic interaction; in the other two, both U(1) and U'(1) do contribute to the electromagnetic interaction. Also, the first two models can approach the standard Weinberg-Salam model as close as one wants; but the third model has limitations on it

    Active learning in Optics (ALO) is a self-funded program under the umbrella of the Abdus Salam International Centre for Theoretical Physics (ICTP) and Quaid-i-Azam University (QAU) to bring physical sciences to traditionally underserved Girls high schools and colleges in Pakistan. There is a significant gender disparity in physical Sciences in Pakistan. In Department of Physics at QAU, approximately 10 to 20% of total students were used to be females from past many decades, but now this percentage is increasing. To keep it up at same pace, we started ALO in January 2016 as a way to provide girls an enriching science experiences, in a very friendly atmosphere. We have organized many one-day activities, to support and encourage girls' students of government high schools and colleges to pursue careers in sciences. In this presentation we will describe our experience and lesson learned in these activities.

  2. Efficient algorithms for construction of recurrence relations for the expansion and connection coefficients in series of Al-Salam-Carlitz I polynomials

    International Nuclear Information System (INIS)

    Doha, E H; Ahmed, H M

    2005-01-01

    Two formulae expressing explicitly the derivatives and moments of Al-Salam-Carlitz I polynomials of any degree and for any order in terms of Al-Salam-Carlitz I themselves are proved. Two other formulae for the expansion coefficients of general-order derivatives D p q f(x), and for the moments x l D p q f(x), of an arbitrary function f(x) in terms of its original expansion coefficients are also obtained. Application of these formulae for solving q-difference equations with varying coefficients, by reducing them to recurrence relations in the expansion coefficients of the solution, is explained. An algebraic symbolic approach (using Mathematica) in order to build and solve recursively for the connection coefficients between Al-Salam-Carlitz I polynomials and any system of basic hypergeometric orthogonal polynomials, belonging to the q-Hahn class, is described

    Electron-positron annihilation at high energies is a good probe of the neutral weak interaction and it is foreseen to be a privileged tool for the study of the neutral weak and electromagnetic currents. In these lectures, we analyse in detail the various tests of the gauge structure of these currents with particular emphasis on the SU(2) X U(1) Salam-Weinberg group. These tests include: study of the coupling of all fermions (leptons and quarks) to the neutral weak current, vector boson (Z 0 and W +- ) production. Higgs meson production and finally 3 and 4 boson couplings - a critical test of non-abelian group structure [fr

  10. Neutral current in the Weinberg-Salam gauge model and elastic scattering of neutrinos and antineutrinos on nucleons

    International Nuclear Information System (INIS)

    Sidhu, D.P.

    1976-01-01

    We study the elastic scattering of neutrinos and antineutrinos on nucleons in the Weinberg-Salam model of the neutral current. In particular, we incorporate into our calculation the experimental cuts relevant to the two recent BNL experiments and also fold in the BNL ν and anti ν spectra. Sensitivity of the calculation to the changes in the axial-vector-meson mass and the Weinberg angle are explored. We conclude that the Weinberg-Salam model prediction for R/sub el/ = / and the differential-cross-section measurements are not inconsistent with the data provided the uncertainty in the mass of the axial-vector meson M/sub A/ is taken into account. Similar predictions are given for anti νN scattering

  12. Unification of inflation, dark energy, and dark matter within the Salam-Sezgin cosmological model

    International Nuclear Information System (INIS)

    Henriques, Alfredo B.; Potting, Robertus; Sa, Paulo M.

    2009-01-01

    We investigate a cosmological model, based on the Salam-Sezgin six-dimensional supergravity theory and on previous work by Anchordoqui, Goldberg, Nawata, and Nunez. Assuming a period of warm inflation, we show that it is possible to extend the evolution of the model back in time, to include the inflationary period, thus unifying inflation, dark matter, and dark energy within a single framework. Like the previous authors, we were not able to obtain the full dark matter content of the universe from the Salam-Sezgin scalar fields. However, even if only partially successful, this work shows that present-day theories, based on superstrings and supergravity, may eventually lead to a comprehensive modeling of the evolution of the universe. We find that the gravitational-wave spectrum of the model has a nonconstant negative slope in the frequency range (10 -15 -10 6 ) rad/s, and that, unlike standard (cold) inflation models, it shows no structure in the MHz/GHz range of frequencies.

    It is increasingly important to support the large numbers of scientists working in remote areas and having low-bandwidth access to the Internet. This will continue to be the case for years to come since there is evidence from PingER performance measurements that the, so-called, digital divide is not decreasing. In this work, we review the collaborative work of The Abdus Salam International Center for Theoretical Physics (ICTP) in Trieste - a leading organization promoting science dissemination in the developing world- and SLAC in Stanford, to monitor by PingER, Universities and Research Institutions all over the developing world following the recent 'Recommendations of Trieste' to help bridge the digital divide. As a result, PingER's deployment now covers the real-time monitoring of worldwide Internet performance and, in particular, West and Central Africa for the first time. We report on the results from the ICTP sites and quantitatively identify regions with poor performance, identify trends, discuss experiences and future work. (author)

    In the framework of the Weinberg-Salam model the p-odd asymmetries Asub(+-) of the processes l -+ +N → l -+ +X with polarized leptons are shown to be related to the inclusive cross sections νsub(μ)(anti vsub(μ))+N → μ - (μ + )+X on an isoscalar target. It is shown that measurements of both Asub(-) and Asub(+) would permit one to test the Weinberg-Salam theory without dynamical assumptions

    In this talk, I recall the history of the development of the unified electroweak theory, incorporating the symmetry-breaking Higgs mechanism, as I saw it from my standpoint as a member of Abdus Salam's group at Imperial College. I start by describing the state of physics in the years after the Second World War, explain how the goal of a unified gauge theory of weak and electromagnetic interactions emerged, the obstacles encountered, in particular the Goldstone theorem, and how they were overcome, followed by a brief account of more recent history, culminating in the historic discovery of the Higgs boson in 2012.

    The one-loop corrections for the Wto e barν decay rate are calculated in the Weinberg-Salam model with arbitrary number of generations. The on-shell renormalization prescription and the 't Hooft-Feynman gauge are employed. Divergences are treated by the dimensional regularization method. Some numerical estimates for the decay rate are given in the three-generation model. It is found that there are significant corrections mainly owing to fermion-mass singularities.

    The Nobel Physics Prize for 1984 was shared by Carlo Rubbia and Simon van der Meer of CERN for their decisive contributions to the project which led to the discovery of the W and Z field particles which carry the weak interaction. Five years before, Sheldon Glashow, Abdus Salam and Steven Weinberg had made the same trip to receive the prize for their crucial roles in piecing together the elegant 'electroweak' gauge theory which unified weak interactions with the electromagnetic force and predicted just where the W and Z particles could be found. In December, the three theorists returned to Stockholm to participate with the 1984 laureates in a specially arranged panel discussion for Stockholm students.

  3. Weinberg-Salam theory in non-commutative geometry

    Ordinary differential calculus on smooth manifold is generalized so as to construct gauge theory coupled to fermions on discrete space M 4 xZ 2 which is an underlying space-time in the non-commutative geometry for the standard model. We can reproduce not only the bosonic sector but also the fermionic sector of the Weinberg-Salam theory without recourse to the Dirac operator at the outset. Treatment of the fermionic sector is based on the generalized spinor one-forms from which the Dirac lagrangian is derived through taking the inner product. Two model constructions are presented using our formalism, both giving the classical mass relation m H = √2m w . The first model leaves the Weinberg angle arbitrary as usual, while the second one predicts sin 2 θ w = 1/4 in the tree level. This prediction is the same as that of Connes but we obtain it from correct hypercharge assignment of 2x2 matrix-valued Higgs field and from vanishing photon mass, thereby dispensing with Connes' 0-trace condition or the equivalent.

  4. Phenomenological analysis of D-brane Pati-Salam vacua

    2010-01-01

    In the present work we perform a phenomenological analysis of the effective low energy models with Pati-Salam (PS) gauge symmetry derived in the context of D-branes. A main issue in these models arises from the fact that the right-handed fermions and the PS-symmetry breaking Higgs field transform identically under the PS symmetry, causing unnatural matter-Higgs mixing effects. We argue that this problem could be solved in particular D-brane setups where these fields arise in different intersections. We further observe that whenever a large Higgs mass term is generated in a particular class of mass spectra, a splitting mechanism -reminiscent of the doublet triplet splitting- may protect the neutral Higgs components from a heavy mass term. We analyze the implications of each individual representation which in principle is available in these models in order to specify the minimal spectrum required to build up a consistent PS model which reconciles the low energy data. A short discussion is devoted on the effects...

    Full text: In his review 'Genesis of Unified Gauge Theories' at the symposium in Honour of Abdus Salam (June, page 23), Tom Kibble of Imperial College, London, looked back to the physics events around Salam from 1959-67. He described how, in the early 1960s, people were pushing to enlarge the symmetry of strong interactions beyond the SU(2) of isospin and incorporate the additional strangeness quantum number. Kibble wrote - 'Salam had students working on every conceivable symmetry group. One of these was Yuval Ne'eman, who had the good fortune and/or prescience to work on SU(3). From that work, and of course from the independent work of Murray Gell- Mann, stemmed the Eightfold Way, with its triumphant vindication in the discovery of the omega-minus in 1964.' Yuval Ne'eman writes - 'I was the Defence Attaché at the Israeli Embassy in London and was admitted by Salam as a part-time graduate student when I arrived in 1958. I started research after resigning from the Embassy in May 1960. Salam suggested a problem: provide vector mesons with mass - the problem which was eventually solved by Higgs, Guralnik, Kibble,.... (as described by Kibble in his article). I explained to Salam that I had become interested in symmetry. Nobody at Imperial College at the time, other than Salam himself, was doing anything in groups, and attention further afield was focused on the rotation - SO(N) - groups. Reacting to my own half-baked schemes, Salam told me to forget about the rotation groups he taught us, and study group theory in depth, directing me to Eugene Dynkin's classification of Lie subalgebras, about which he had heard from Morton Hamermesh. I found Dynkin incomprehensible without first learning about Lie algebras from Henri Cartan's thesis, which luckily had been reproduced by Dynkin in his 1946 thesis, using his diagram method. From a copy of a translation of Dynkin's thesis which I found in the British Museum Library, I

    Full Text Available The present work deals with the identification of the potential and generating capability of oil generation in the Jurassic source rocks in the Salam-3x well. This depending on the organo-geochemical analyses of cutting samples representative of Masajid, Khatatba and Ras Qattara formations, as well as, representative extract samples of the Khatatba and Ras Qattara formations. The geochemical analysis suggested the potential source intervals within the encountered rock units as follows: Masajid Formation bears mature source rocks and have poor to fair generating capability for generating gas (type III kerogen. Khatatba Formation bears mature source rock, and has poor to good generating capability for both oil and gas. Ras Qattara Formation constituting mature source rock has good to very good generating capability for both oil and gas. The burial history modeling shows that the Masajid Formation lies within oil and gas windows; Khatatba and Ras Qattara formations lie within the gas window. From the biomarker characteristics of source rocks it appears that the extract is genetically related as the majority of them were derived from marine organic matters sources (mainly algae deposited under reducing environment and take the direction of increasing maturity and far away from the direction of biodegradation. Therefore, Masajid Formation is considered as effective source rocks for generating hydrocarbons, while Khatatba and Ras Qattara formations are the main source rocks for hydrocarbon accumulations in the Salam-3x well.

    On the basis of the climate change simulations conducted using a high resolution regional climate model, the Abdus Salam International Centre for Theoretical Physics (ICTP) Regional Climate Model, RegCM3, at 25 km grid spacing, future changes in snow cover over China are analyzed. The simulations are carried out for the period of 1951–2100 following the IPCC SRES A1B emission scenario. The results suggest good performances of the model in simulating the number of snow cover days and the snow cover depth, as well as the starting and ending dates of snow cover to the present day (1981–2000). Their spatial distributions and amounts show fair consistency between the simulation and observation, although with some discrepancies. In general, decreases in the number of snow cover days and the snow cover depth, together with postponed snow starting dates and advanced snow ending dates, are simulated for the future, except in some places where the opposite appears. The most dramatic changes are found over the Tibetan Plateau among the three major snow cover areas of Northeast, Northwest and the Tibetan Plateau in China.

  13. Lepton-flavour violation in a Pati-Salam model with gauged flavour symmetry

    Combining Pati-Salam (PS) and flavour symmetries in a renormalisable setup, we devise a scenario which produces realistic masses for the charged leptons. Flavour-symmetry breaking scalar fields in the adjoint representations of the PS gauge group are responsible for generating different flavour structures for up- and down-type quarks as well as for leptons. The model is characterised by new heavy fermions which mix with the Standard Model quarks and leptons. In particular, the partners for the third fermion generation induce sizeable sources of flavour violation. Focusing on the charged-lepton sector, we scrutinise the model with respect to its implications for lepton-flavour violating processes such as μ→eγ, μ→3e and muon conversion in nuclei.

    Rousset, A.

    1996-06-01

    In order to simplify the description of forces, the physicists want to reduce the number of four interactions to a smaller one. They want to unify them. Einstein tried to unify the electromagnetic interaction and the gravitation interaction but it was probably the most difficult to unify. during the sixties, the American physicists Sheldon Glashow and Steven Weinberg and the Pakistani Abdus Salam ( each rewarded by the Nobel price of 1979) propose to unify the weak and electromagnetic interactions interactions under the form of an only interaction, the electro-weak interaction. To check the validity of this theory exist the demonstration by the weak neutral currents. In 1973, European physicians which analyzed photos taken in the bubble chamber called Gargamelle brought the experimental proof. This book tells the story of this discovery. (N.C.)

The workshop consisted of five weeks of lecture courses followed by practical computer exercises on nuclear data treatment and design of nuclear power systems. The spectrum of topics is wide enough to timely cover the state-of-the-art and the perspectives of this broad field. The first two weeks were devoted to nuclear reaction models and nuclear data evaluation. Nuclear data processing for applications to reactor calculations was the subject of the third week. On the last two weeks reactor physics and on-going projects in nuclear power generation, waste disposal and safety were presented.

  16. Higgs potential and spinor connection within Weinberg-Salam model

    International Nuclear Information System (INIS)

    Trostel, R.

    1987-01-01

    We arrive at a theory of the Higgs potential by extending the usual concept of the covariant derivative containing the gauge fields to one which also contains the Higgs fields, by using a spinor connection compatible under local gauge transformations. Not only the Yukawa couplings are geometrized by this procedure but also the nonlinear Higgs potential naturally appears within the curvature of the corresponding spinor connection. Taking the gauge group to be SU(2) x U(1), we arrive for the leptonic Weinberg Salam model at a Weinberg angle prediction of sin 2 θ=1/4 and at a Higgs mass of about 263-270 GeV without using any supersymmetry argument. Taking the gauge group to be SU(3) C x SU(2) x U(1) the above leptonic result is obtained only if e 2 /g S 2 is sufficiently small, which is approximately true. Working with two independent Higgs doublets we arrive at a Higgs mass sum rule, where two Higgs must have a mass of about 188 GeV. (author)

    The theoretical physics group at London's Imperial College in 1959 had three permanent faculty: Abdus Salam, his erstwhile thesis supervisor Paul Matthews, and John C.Taylor. I joined as a lecturer the following year. In those early days we had lots of visitors, both long- and short-term - Murray Gell-Mann, Ken Johnson, John Ward, Lowell Brown, Gordon Feldman and Steven Weinberg. About a year after I arrived we were transferred from the Mathematics to the Physics Department under the formidable Patrick (P.M.S.) Blackett. Having been brought up in the Cavendish Laboratory tradition under Lord Rutherford, Blackett was rather scornful of theoretical physicists, but he knew a good thing when he saw one and had persuaded Salam to join the rapidly expanding Physics Department. In 1960 field theory was widely regarded as very passé. It had had its triumphs: renormalization theory had made sense of divergences, and quantum electrodynamics had been magnificently vindicated. But field theory didn't seem to work for anything else, particularly not for the strong interactions, and was definitely out of fashion. There were, however, a few places in the world where field theory was still studied unashamedly. Imperial College was one. Harvard was certainly another; many of our visitors over the next few years were Julian Schwinger's students

  19. Perturbation constraint on particle masses in the Weinberg-Salam model with two massless Higgs doublets

    1980-01-01

    The Weinberg-Salam model with two Higgs doublets is investigated. The spontaneous breakdown of the gauge symmetry is assumed to be produced by the Coleman-Weinberg mechanism, keeping gauge hierarchies in grand unified theories in mind. A discrete symmetry is introduced to secure flavor-diagonal Yukawa interactions of neutral Higgs bosons and the absence of the axion. Bounds on various masses are obtained by imposing coupling constants to lie in a finite range for the validity of the perturbation theory. It will be found that there must be at least one Higgs boson whose mass is lighter than 40 GeV, in order to satisfy the perturbation constraint at the unification mass scale in grand unified theories.

    Future changes in the climate regimes over China as measured by the Kppen climate classification are reported in this paper. The analysis is based on a high-resolution climate change simulation conducted by a regional climate model (the Abdus Salam International Center for Theoretical Physics (ICTP) RegCM3) driven by the global model of Center for Climate System Research (CCSR)/National Institute for Environment Studies (NIES)/Frontier Research Center for Global Change (FRCGC) MIROC3.2_hires (the Model for Interdisciplinary Research on Climate) under the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario. Validation of the model performances is presented first. The results show that RegCM3 reproduces the present-day distribution of the Kppen climate types well. Significant changes of the types are found in the future over China, following the simulated warming and precipitation changes. In southern China, the change is characterized by the replacement of subtropical humid (Cr) by subtropical winter-dry (Cw). A pronounced decrease of the cold climate types is found over China, e.g., tundra (Ft) over the Tibetan Plateau and sub-arctic continental (Ec) over northeast China. The changes are usually greater in the end compared with the middle of the 21st century.

    1984-01-01

    The Glashow-Weinberg-Salam theory of unified electromagnetic and weak interactions, believed to be the correct quantum theory of these interactions, possesses the great advantage of being renormable. Thus the perturbation theory is applicable to calculate the radiative corrections of the tree-graph results. The present paper describes the detailed calculation of one-loop corrections to beta decay of hyperons. After defining the theory and fixing the gauge and renormalization conventions, the equations of weak and electromagnetic one-loop corrections are derived. Numerical evaluation of the equations was helped by algebraic and integrator computer codes. The results are directly comparable to experimental data. (D.Gy.)

On 25 January 1983, this historic press conference announced the observation of W particles in the UA1 experiment at CERN, and was followed by another in May when Z particles had been found. Natural phenomena at this scale are described by four forces, gravity, electromagnetism and the strong and weak nuclear forces. But in 1968 a new theory predicted that electromagnetism and the weak nuclear force were manifestations of a single 'electroweak' interaction, proposing that it would be communicated by the charged W+ and W- bosons and the neutral Z0 boson. In 1979 Sheldon Glashow, Abdus Salam and Steven Weinberg won the Nobel Prize for Physics for this work. Finding the bosons predicted by the theory involved a huge effort.

    Generalized differential calculus on discrete space M 4 xZ 2 which is an underlying space-time in the non-commutative geometry for the standard model is reformulated in terms of a Z 2 -graded algebra, even and odd elements of which being pairs of complex matrices defined over Minkowski space-time with different properties of product and involution. It is shown that the Z 2 -grading is equivalent to that of Coquereaux et al. if the pair is represented by 2x2 matrices, although our formalism has closer contact with the differential calculus on the discrete space. A graded differential algebra is then defined, in which the exterior derivative with respect to the pair is assumed to determine the pattern of symmetry breaking of the theory. On the basis of it the Weinberg-Salam theory in both bosonic and fermionic sectors is constructed. It is pointed out that, in contrast to usual assertion in non-commutative geometry, the Weinberg angle and the Higgs mass in the tree level are not fixed separately but related through m H = 2√2εm W sinθ W . Connes' prescription of constructing gauge-invariant Lagrangian, which is based on the assumption that there arise only logarithmic divergences from one-loop diagrams, corresponds to the case ε = 1. In principle, however, the parameter ε is arbitrary due to possible presence of Sitarz' linear term so that noncommutative geometry alone says nothing about the Higgs mass. (author)

    2008-08-01

    The International Atomic Energy Agency (IAEA) and the Abdus Salam International Centre for Theoretical Physics (ICTP) organised an expert meeting at the ICTP from 4 to 8 February 2008 to discuss model codes for spallation reactions. These nuclear reactions play an important role in a wide domain of applications ranging from neutron sources for condensed matter and material studies, transmutation of nuclear waste and rare isotope production to astrophysics, simulation of detector set-ups in nuclear and particle physics experiments, and radiation protection near accelerators or in space. The simulation tools developed for these domains use nuclear model codes to compute the production yields and characteristics of all the particles and nuclei generated in these reactions. These codes are generally Monte-Carlo implementations of Intra-Nuclear Cascade (INC) or Quantum Molecular Dynamics (QMD) models, followed by de-excitation (principally evaporation/fission) models. Experts have discussed in depth the physics contained within the different models in order to understand their strengths and weaknesses. Such codes need to be validated against experimental data in order to determine their accuracy and reliability with respect to all forms of application. Agreement was reached during the course of the workshop to organise an international benchmark of the different models developed by different groups around the world. The specifications of the benchmark, including the set of selected experimental data to be compared to the models, were also defined during the workshop. The benchmark will be organised under the auspices of the IAEA in 2008, and the first results will be discussed at the next Accelerator Applications Conference (AccApp'09) to be held in Vienna in May 2009.

    2007-07-01

    The application of quantum mechanics to information related fields such as communication, computation and cryptography is a fast growing line of research that has been witnessing an outburst of theoretical and experimental results, with possible practical applications. On the one hand, quantum cryptography with its impact on secrecy of transmission is having its first important actual implementations; on the other hand, the recent advances in quantum optics, ion trapping, BEC manipulation, spin and quantum dot technologies allow us to put to direct test a great deal of theoretical ideas and results. These achievements have stimulated a reborn interest in various aspects of quantum mechanics, creating a unique interplay between physics, both theoretical and experimental, mathematics, information theory and computer science. In view of all these developments, it appeared timely to organize a meeting where graduate students and young researchers could be exposed to the fundamentals of the theory, while senior experts could exchange their latest results. The activity was structured as a school followed by a workshop, and took place at The Abdus Salam International Center for Theoretical Physics (ICTP) and The International School for Advanced Studies (SISSA) in Trieste, Italy, from 12-23 June 2006. The meeting was part of the activity of the Joint European Master Curriculum Development Programme in Quantum Information, Communication, Cryptography and Computation, involving the Universities of Cergy-Pontoise (France), Chania (Greece), Leuven (Belgium), Rennes1 (France) and Trieste (Italy). This special issue of Journal of Physics A: Mathematical and Theoretical collects 22 contributions from well known experts who took part in the workshop. They summarize the present day status of the research in the manifold aspects of quantum information. The issue is opened by two review articles, the first by G Adesso and F Illuminati discussing entanglement in continuous variable

    We report on the presence of new axially symmetric monopoles, antimonopoles and vortex-rings solutions of the SU(2)×U(1) Weinberg-Salam model of electromagnetic and weak interactions. When the ϕ-winding number n = 1, and 2, the configurations are monopole-antimonopole pair (MAP) and monopole-antimonopole chain (MAC) with poles of alternating sign magnetic charge arranged along the z-axis. Vortex-rings start to appear from the MAP and MAC configurations when the winding number n = 3. The MAP configurations possess zero net magnetic charge whereas the MAC configurations possess net magnetic charge of 4 πn / e. In the MAP configurations, the monopole-antimonopole pair is bounded by the Z0 field flux string and there is an electromagnetic current loop encircling it. The monopole and antimonopole possess magnetic charges ± 4πn/e sin2θW respectively. In the MAC configurations there is no string connecting the monopole and the adjacent antimonopole and they possess magnetic charges ± 4 πn/e respectively. The MAC configurations possess infinite total energy and zero magnetic dipole moment whereas the MAP configurations which are actually sphalerons possess finite total energy and magnetic dipole moment. The configurations were investigated for varying values of Higgs self-coupling constant 0 ≤ λ ≤ 40 at Weinberg angle θW = π/4.

  16. The Interplay Between GUT and Flavour Symmetries in a Pati-Salam x S4 Model

    2010-01-01

    Both Grand Unified symmetries and discrete flavour symmetries are appealing ways to describe apparent structures in the gauge and flavour sectors of the Standard Model. Both symmetries put constraints on the high energy behaviour of the theory. This can give rise to unexpected interplay when building models that possess both symmetries. We investigate on the possibility to combine a Pati-Salam model with the discrete flavour symmetry $S_4$ that gives rise to quark-lepton complementarity. Under appropriate assumptions at the GUT scale, the model reproduces fermion masses and mixings both in the quark and in the lepton sectors. We show that in particular the Higgs sector and the running Yukawa couplings are strongly affected by the combined constraints of the Grand Unified and family symmetries. This in turn reduces the phenomenologically viable parameter space, with high energy mass scales confined to a small region and some parameters in the neutrino sector slightly unnatural. In the allowed regions, we can r...

    Studies on the architectural heritage can now be supported by three-dimensional reconstruction of actual buildings. The 3D digital model can be an effective medium for documenting the current state of historic buildings but also to create a resource for researchers who conduct their analysis on historical evolution. Architectural photogrammetry has its own specifications in relation to other photogrammetric applications, however it meets these expectations. The traditional approach requires the use of metric cameras but with the development of computational techniques, this requirement is overcome and opens the way for the use of non-metric camera. The use of the shots that is no longer restricted to the parallel configuration of bundles, the images may be convergent, horizontal or oblique. Combining and modelling several cameras increasingly powerful in resolution and stability, has great scope and the same workflow can be used in varied applications. ISPRS and ICOMOS created CIPA because they both believe that a monument can be restored and protected only when it has been fully measured and documented and when its development has been documented several times, i.e. monitored, also with respect to its environment, and stored in proper heritage information and management systems. In this paper the 3D modelling of an important cultural site using terrestrial photogrammetric techniques for architectural preservation is presented. The site is the mosque of Abdullah Ibn Salam, Built in 1880 at the initiative of Simon Kanoui, also known as the Great Synagogue of Oran was inaugurated in 1918 only. It was one of the largest and most beautiful synagogues in North Africa. It was built with stone imported from Jerusalem. This place of worship became in 1975 the mosque of Abdullah Ibn Salam who was a rich Jew of Medina who was converted to Islam. The structure is modelled using 321 oriented photos taken in five series of shots that cover all the façade and the interior of

    We were deeply saddened to learn that Gordon Fraser had passed away on 3 January. During his 25-year career at CERN, until his retirement in 2002, he made many valuable contributions to the Laboratory, in particular as editor of CERN Courier.   Gordon’s life in science began at Imperial College London, where he obtained a PhD with the theory group of the future Nobel laureate Abdus Salam. He then spent time at Tel Aviv University in Yuval Ne’eman’s group and at Brighton University, before changing career to become a journalist, at first for Computer Weekly in London. He moved into scientific editing at the Rutherford Appleton Laboratory in 1975 and it was from there that he was hired to join the publications team at CERN in 1977. By 1982 Gordon had become the editor of the CERN Courier. During his time at the helm, both particle physics and the Courier changed considerably. Under his careful stewardship aspects of publishing were outsourced, leading to a...

    The influence of the temperature on Metal Gate/Al2O3/n-InGaAs stacks has been studied by means of capacitance-voltage (C-V) hysteresis and flat band voltage as function of both negative and positive stress fields. It was found that the de-trapping effect decreases at low-temperature, indicating that the de-trapping of trapped electrons from oxide traps may be performed via Al2O3/InGaAs interface defects. The dependence of the C-V hysteresis on the stress field at different temperatures in our InGaAs stacks can be explained in terms of the defect spatial distribution. An oxide defect distribution can be found very close to the metal gate/Al2O3 interface. On the other side, the Al2O3/InGaAs interface presents defects distributed from the interface into the bulk of the oxide, showing the influence of InGaAs on Al2O3 in terms of the spatial defect distribution. At the present, he is a research staff of the National Council of Science and Technology (CONICET), working in the National Commission of Atomic Energy (CNEA) in Buenos Aires, Argentina, well embedded within international research collaboration. Since 2008, he is Professor at the National Technological University (UTN) in Buenos Aires, Argentina. Dr. Palumbo has received research fellowships from: Marie Curie Fellowship within the 7th European Community Framework Programme, Abdus Salam International Centre for Theoretical Physics (ICTP) Italy, National Council of Science and Technology (CONICET) Argentina, and Consiglio Nazionale delle Ricerche (CNR) Italy.

  20. How to approach continuum physics in the lattice Weinberg-Salam model

    International Nuclear Information System (INIS)

    Zubkov, M. A.

    2010-01-01

    We investigate the lattice Weinberg-Salam model without fermions numerically for the realistic choice of coupling constants correspondent to the value of the Weinberg angle θ W ∼30 deg., and bare fine structure constant around α∼(1/150). We consider the values of the scalar self-coupling corresponding to Higgs mass M H ∼100, 150, 270 GeV. It has been found that nonperturbative effects become important while approaching continuum physics within the lattice model. When the ultraviolet cutoff Λ=(π/a) (where a is the lattice spacing) is increased and achieves the value around 1 TeV, one encounters the fluctuational region (on the phase diagram of the lattice model), where the fluctuations of the scalar field become strong. The classical Nambu monopole can be considered as an embryo of the unphysical symmetric phase within the physical phase. In the fluctuational region quantum Nambu monopoles are dense, and therefore, the use of the perturbation expansion around the trivial vacuum in this region is limited. Further increase of the cutoff is accompanied by a transition to the region of the phase diagram, where the scalar field is not condensed (this happens at the value of Λ around 1.4 TeV for the considered lattice sizes). Within this region further increase of the cutoff is possible, although we do not observe this in detail due to the strong fluctuations of the gauge boson correlator. Both above mentioned regions look unphysical. Therefore we come to the conclusion that the maximal value of the cutoff admitted within lattice electroweak theory cannot exceed the value of the order of 1 TeV.

    Full Text Available The Abdus Salam International Center for Theoretical Physics (ICTP version 4.4 Regional Climate Model (RegCM4 is used to investigate the rainfall response to cooler/warmer sea surface temperature anomaly (SSTA forcing in the Indian and Atlantic Oceans. The effect of SSTA forcing in a specific ocean basin is identified by ensemble, averaging 10 individual simulations in which a constant or linearly zonally varying SSTA is prescribed in individual basins while specifying the 1971–2000 monthly varying climatological sea surface temperature (SST across the remaining model domain. The nonlinear rainfall response to SSTA amplitude also is investigated by separately specifying +1K, +2K, and +4K SSTA forcing in the Atlantic and Indian Oceans. The simulation results show that warm SSTs over the entire Indian Ocean produce drier conditions across the larger Blue Nile catchment, whereas warming ≥ +2K generates large positive rainfall anomalies exceeding 10 mm·day−1 over drought prone regions of Northeastern Ethiopia. However, the June–September rainy season tends to be wetter (drier when the SST warming (cooling is limited to either the Northern or Southern Indian Ocean. Wet rainy seasons generally are characterized by deepening of the monsoon trough, east of 40°E, intensification of the Mascarene high, strengthening of the Somali low level jet and the tropical easterly jet, enhanced zonal and meridional vertically integrated moisture fluxes, and steeply vertically decreasing moist static energy. The opposite conditions hold for dry monsoon seasons.

    Full Text Available In the context of climate change in West Africa characterized by a reduction of precipitation, this study was conducted to evaluate the impact of climate change on water resources from now to the end of the 21st century in the transboundary watershed of the Sassandra River shared by Guinea and Côte d’Ivoire. Historical and future climate data of Representative Concentration Pathways (RCPs 4.5 and 8.5 were projected with the Abdus Salam International Centre for Theoretical Physics (ICTP Regional Climate Model (RegCM4. The hydrological modeling of the river basin was carried out with the conceptual hydrological model, GR2M, a monthly time steps model that allows for the assessment of the discharge of the Sassandra River for each climate scenario according to the time periods 2021–2040 (Horizon 2030, 2041–2060 (Horizon 2050, 2061–2080 (Horizon 2050, and 2061–2080 (Horizon 2090. The results show a reduction in annual discharge when compared to the baseline (1961–1980. For RCP 4.5, the observed values go from −1.2% in 2030 to −2.3% in 2070 and rise to −2.1% in 2090. Concerning RCP 8.5, we saw a variation from −4.2 to −7.9% in Horizons 2030 and 2090, respectively. With the general decrease in rainfall in West Africa, it is appropriate to assess the impact on water resources of the largest rivers (Niger, Gambia, and Senegal that irrigate the Sahelo–Saharian zone.

    The non-conventional energy activities started in 1974, on the island of Procida, Italy. About 50 leading physicists and engineers got together for two weeks in September to discuss the states of the art and consult with each other about various devices and ways of energy conversion. The esteemed Nobel Prize Laureate, Professor Abdus Salam, accepted to have the first meeting on non-conventional energy at the ICTP, Trieste, in September 1977. In 1987, the meeting was once again back in Trieste, Italy. Also, during the even years since 1978 until 1986, meetings were held in Trieste in the French language. The results of the last 10 years at ICTP are very clear to all fellow scientist and engineers. Some 150 applicants are chosen every year. The workshop is being graded gradually to emphasize the high technology and up-to-date achievements in the field. A good proportion of the physicists who were with us from the beginning are now top experts in the field and in charge of existing programmes in their own countries. The present programme emphasized the following topics: Material Science; Solar Energy Conversion with concentration on Photovoltaic Conversion; and Energy Storage. Refs, figs and tabs

    In the present study, the interconnection between the surface water of El-Salam Canal and the shallow groundwater in the adjacent aquifer has been discussed using both the environmental isotopes and the chemical analyses of the different water bodies along the canal trajectory from Faraskour in the west to Balousa in the east. The isotopic techniques were applied to investigate this relationship and to estimate the possible contribution from various sources such as groundwater, sea water and/or irrigation water, and finally to determine the extent of mixing between El-Salam Canal and the adjacent aquifers. Since the groundwater in the area is saline (more than 10000 ppm) while the mixed canal water is mainly fresh (less than 1000 ppm), the interconnection between the canal water and surrounding shallow groundwater leads to one of the following two hydrologic processes; seepage from the canal water to the shallow groundwater which means fresh water losses or leakage from the groundwater into the surface water which means water quality deterioration The present study aims to detect the hydraulic interconnection between the two water bodies by using environmental isotope techniques as well as detailed chemical analysis. For this purpose, 31 water samples from both surface water and groundwater were collected and analyzed for 18 O and 2 H contents as well as 44 representative water samples were collected and analyzed for the chemical components (anions and cations) as a major ions and minor constituents. The distribution of the analyzed samples on the 18 O vs. D diagram indicated that the samples could be classified into three genetic groups representing different sources of water. The first group reflects a contribution from evaporated rain water prior to infiltration to the groundwater, the second group represents a mixing trend between both of El-Farma drain water and El-Manzala lake water with the groundwater which have enriched isotopic values as well as high

    Full Text Available Introduction: Central venous catheter (CVC plays an essential part in clinical management of patients admitted in Intensive Care Unit (ICU, even though catheterization is an invasive procedure that may facilitate bacterial migration from the skin surrounding the catheter insertion site to the catheter tip, representing a risk factor for the arise of bacteraemia and sepsis. Aim of our study was to assess the prevalence of micro-organisms found as responsibles of CVC-related infections and check their correspondence with those found in blood cultures collected from the same patients. Methods: The study was conduced from April 2008 to March 2009. In this period were analysed 29 CVC samples sent from ICU to the laboratory of the Salam Center for Cardiac Surgery of Khartoum (Sudan. CVC was removed after pericatheter skin disinfection and its tip was cut, put in a sterile container and finally sent to the laboratory, where it was immersed in Brain Heart Infusion (BHI and incubated at 37°C.A first culture of the sample on Blood Agar plate was done after an incubation period of 1 hour, the second one after 24 hours. In case of bacterial growth were practiced identification and sensitivity test of the isolated bacteria. Results: Of the 29 analysed samples 38% showed bacterial growth of which 27% caused by gram positive and 73% by gram negative bacteria. The identification tests showed also that among gram positive-related infection predominated those caused by Methicillin-Resistent Staphylococcus aureus (MRSA (67%, while among the gram negative infections predominated those caused by Pseudomonas spp (57%, followed by Enterobacter spp and Serratia spp. Conclusion: All the above mentioned infections were confirmed by examination of blood cultures collected simultaneously from the same patients. Furthermore the study showed that 73% of infections affected post-operative patients rather than those waiting for surgery.

    Full Text Available The study of the ecology of fermented sausage is fundamental to understand the physical and chemical changes that happen during fermentation and maturation. The aim of the present study was to determine the microbiological characteristics of sausages produced by spontaneous fermentation. Fifty samples of sausages produced in the South of Brazil by different small manufacturers were analyzed for the following microbiota: aerobic mesophilic bacteria; Micrococcaceae; mold and yeast; lactic acid bacteria; total and fecal coliforms; coagulase-positive Staphylococcus, and Salmonella. In most samples (72%, the count of lactic bacteria was higher than 6 log10 cfu.g-1, and the samples with the highest counts were above 8 log10 cfu.g-1. The counts of Micrococcaceae in most samples were between 5 log10 and 7 log10 cfu.g-1. With respect to the presence of molds and yeasts, there was a significant variation among the samples with counts ranging from 2 log10 cfu.g-1 and 6 log10 cfu.g-1. From the data obtained, it was possible to conclude that 24% of the analyzed samples did not comply with the current law in Brazil since the levels of fecal coliforms or coagulase-positive Staphylococcus exceeded the maximum limit allowed.O estudo da ecologia de salames fermentados faz-se necessário para entender as mudanças físicas e químicas que ocorrem durante a fermentação e maturação.

    Full Text Available Dry sausages have been considered ready-to-eat products with low risk of causing listeriosis due to the hurdles created during the manufacturing process such as low pH and a w, high salt concentration and presence of lactic acid bacteria (LAB. However, several studies have detected survival of Listeria monocytogenes in these products and also shown that process parameters, LAB and L. monocytogenes strains directly influence the results. In this work, survival of the pathogen in sausages prepared with three different formulations (one standard formulation, one formulation added of Lactobacillus plantarum and one added of 2% sodium lactate, using the manufacturing process usually employed in Brazil, was evaluated. Naturally contaminated sausages presented a small increase in the counts of L. monocytogenes in the first days of the process, followed by a gradual decrease until the end of the process. In experimentally contaminated samples containing L. plantarum, the reduction of counts of L. monocytogenes during processing was considerable, but there wasn´t significant differences between the treatments.Salames têm sido considerados produtos prontos para o consumo com baixo risco de provocar listeriose devido aos obstáculos criados no processo de fabricação e suas características de pH e atividade água baixos, alta concentração de sal e presença de bactérias lácticas. Entretanto, a sobrevivência de Listeria monocytogenes nesta classe de produtos é verificada e estudos de processo visando à redução da contaminação por este patógeno, têm demonstrado que particularidades como variação dos parâmetros de processo, cepas de bactérias lácticas e de L. monocytogenes influenciam diretamente os resultados. Neste estudo três formulações foram avaliadas (uma padrão, uma com inoculação da cultura Lactobacillus plantarum e outra com adição 2% de lactato de sódio empregando parâmetros de processo comumente praticados no Brasil

  14. With neutrino masses revealed, proton decay is the missing link

    Pati, J.C.

    1999-01-01

    By way of paying tribute to Abdus Salam, I recall the ideas of higher unification that he and I initiated. I discuss the current status of those ideas in the light of recent developments, including those of: (a) gauge coupling unification, (b) discovery of neutrino-oscillation at SuperKamiokande, and (c) ongoing searches for proton decay. It is noted that the mass of ν τ (∼ 1/20 eV), suggested by the SuperK result, provides clear support for the route to higher unification based on the ideas of (i) SU(4)-color, (ii) left-right symmetry and (iii) supersymmetry. The change in perspective, pertaining to both gauge coupling unification and proton decay, brought forth by supersymmetry and superstrings, is noted. And, the beneficial roles of string-symmetries in addressing certain naturalness problems of supersymmetry, including that of rapid proton decay, are emphasized. Further, it is noted that with neutrino masses and coupling unification revealed, proton decay is the missing link. Following recent joint work with K. Babu and F. Wilczek, based on supersymmetric unification, it is remarked that the SuperKamiokande result on neutrino oscillation in fact enhances the expected rate of proton decay compared to prior estimates. Thus, assuming supersymmetric unification, one expects that the discovery of proton decay should not be far behind. (author)

    Full Text Available More than 12 × 109 m3/year of Nile Delta drainage water is annually discharged into the Mediterranean Sea. El-Salam (peace canal, having a mixture of such drainage water and the Nile water (1:1 ratio, crosses the Suez canal eastward to the deserts of north Sinai. The suitability of the canal water for agriculture is reported here. Representative samples were obtained during two successive years to follow effects of seasonal and spatial distribution, along the first 55 km course in north Sinai, on the water load of total bacteria, bacterial indicators of pollution, and chemical and heavy metals contents. In general, the canal water is acceptable for irrigation, with much concern directed towards the chemical contents of total salts (EC, Na and K, as well as the trace elements Cd and Fe. Extending the canal course further than 30 km significantly lowered the fecal pollution rate to the permissible levels of drinking water. Results strongly emphasize the need for effective pre-treatment of the used drainage water resources prior mixing with the Nile water.

    The active learning project consists in a series of workshops for educators, researchers and students and promotes an innovative method of teaching physics using simple, inexpensive materials that can be fabricated locally. The objective of the project is to train trainers and inspire students to learn physics. The workshops are based on the use of laboratory work and hands-on activities in the classroom. The interpretation of these experiments is challenging for some students, and the experiments can lead to a significant amount of discussion. The workshops are organized within the framework of the project ``Active Learning in Optics and Photonics" (ALOP) mainly funded by UNESCO, with the support of ICTP (Abdus Salam International Centre for Theoretical Physics) and SPIE. ALOP workshops offer high school, college or university physics teachers the opportunity to improve their conceptual understanding of optics. These workshops usually run for five days and cover several of the topics usually found in any introductory university physics program. Optics and photonics are used as subject matter because it is relevant as well as adaptable to research and educational conditions in many developing countries [1]. In this paper, we will mainly focus on a specific topic of the ALOP workshops, namely optical communications and Wavelength Division Multiplexing technology (WDM). This activity was originally developed by Mazzolini et al [2]. WDM is a technology used in fibre-optic communications for transmitting two or more separate signals over a single fibre optic cable by using a separate wavelength for each signal. Multiple signals are carried together as separate wavelengths of light in a multiplexed signal. Simple and inexpensive WDM system was implemented in our laboratory using light emitting diodes or diode lasers, plastic optical fibres, a set of optical filters and lenses, prism or grating, and photodiodes. Transmission of audio signals using home-made, simple

Taking into account that the participants to the meetings represented only a very small subset of those scientists who might be interested in hearing what John Bell said in probably his last lecture, we considered that it would be useful for the scientific community interested in foundational problems to publish the text of this lecture in order to make it accessible to everybody. The lecture was preceded by a presentation by the Chairman, Alain Aspect, which we have also included. Due to the aforementioned low quality of the recording it has not been easy to pass from the tape to the text we are presenting below, and we have to thank, for her precious collaboration, Dr Julia Filingeri who did most of the work, as well as Mrs Anne Gatti from ICTP, Professors Detlef Dueurr and Sheldon Goldstein, and the staff of IOP Publishing who contributed in an essential way in deciphering some particularly difficult passages. Obviously, we take full responsibility for any possible inappropriate rendering of the original talk. We thank the Abdus Salam International Centre for Theoretical Physics for authorizing IOP Publishing to publish this important document. Some final remarks are in order.

  20. Order αGsub(μ) corrections to the parity-violating electron-quark potential in the Weinberg-Salam theory: parity-violations in one-electron atoms

    Lynn, B.W.

    We have calculated the order αGsub(μ) corrections to the order Gsub(μ) parity-violating (PV) electron-quark potential Hsub(PV)sup(e-q) at q 2 =0 in the standard SU(2)sub(L) x U(1) theory using a renormalization scheme which has Msub(W), Msub(Z) and Msub(H) (Higgs' mass) as input parameters. We then use SU(3) relations to write an effective PV electron-nucleon potential Hsub(PV)sup(e-N) in terms of the dimensionless parameters Csub(1P), Csub(1N) (nuclear spin independent) Csub(2P), Csub(2N) (nuclear spin dependent) and Csub(3P), Csub(3N) (electron anomalous magnetic moment dependent). For ssub(theta) 2 identical to 1-Msub(W) 2 /Msub(Z) 2 approx.= .23 and small Higgs' mass Msub(H) or approx.1 TeV. Csub(3P), and Csub(3N) are first induced at one loop and are small. We show that Csub(2P) and Csub(2N) suffer from large uncertainties due to the strong interactions which make the theoretical interpretation of experiments designed to measure these quantities less clear than was previously thought. The other parameters are relatively free from strong interaction uncertainties. We review the diseases of the old 1934 four-fermion theory and give an overview of the renormalization of the Weinberg-Salam theory. We discuss the possibility of high-precision experiments in one-electron atoms to measure these radiative corrections and remind the reader of a previously proposed experiment in hydrogen or deuterium which will measure Csub(1P) or Csub(1P)+Csub(1N) respectively.

    Full Text Available Society services activity on cattle waste management system have been implemented in Sido Mulyo Livestock Farmers Group at Pulosari, Jumoyo, Salam, Magelang. Animal byproducts that consist of feces and urine of cattle wastewas processed into organic fertilizer compost and liquid fertilizer. Sido Mulyo Livestock Farmer Group has one unit of 20 m3 biodigester to accommodate the feces from approximately 30 cattle owned by the group member. Biogas has been used as a fuel source for family group members located around the cage. Slurry resulted from anaerobic digestion of biodigester disposed to pastures located on the right side of the cage. Ownership system in the groupis every group member hasa responsibility for taking care of their own cattle. The number of livestock owned by each member of the SidoMulyoLivestock Farmers Group ranged between 1 to 4 cattle. Society services methods that have been implemented was in the form of mentoring for a member of the Sido Mulyogroup.The other activities that have been implemented was the training and development of cattle industry, especially the handling of livestock waste in the form of feces, urine, and the feed residue. The activities was continued by the manufacture of compost packaging design, followed by the last series of activities such as monitoring and program development. The enthusiasm of the group members in joining to the extension activities is very good. The timing of the extension are determined in the afternoon after members of the group have finished searching feed for their cattle. The sustainability forwaste processing into organic fertilizer compost and liquid organic fertilizer becomes a major concern, because it is highly dependent on consumer demand.

  2. Best convective parameterization scheme within RegCM4 to downscale CMIP5 multi-model data for the CORDEX-MENA/Arab domain

    A suitable convective parameterization scheme within Regional Climate Model version 4.3.4 (RegCM4) developed by the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy, is investigated through 12 sensitivity runs for the period 2000-2010. RegCM4 is driven with European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-Interim 6-hourly boundary condition fields for the CORDEX-MENA/Arab domain. Besides ERA-Interim lateral boundary conditions data, the Climatic Research Unit (CRU) data is also used to assess the performance of RegCM4. Different statistical measures are taken into consideration in assessing model performance for 11 sub-domains throughout the analysis domain, out of which 7 (4) sub-domains give drier (wetter) conditions for the area of interest. There is no common best option for the simulation of both rainfall and temperature (with lowest bias); however, one option each for temperature and rainfall has been found to be superior among the 12 options investigated in this study. These best options for the two variables vary from region to region as well. Overall, RegCM4 simulates large pressure and water vapor values along with lower wind speeds compared to the driving fields, which are the key sources of bias in simulating rainfall and temperature. Based on the climatic characteristics of most of the Arab countries located within the study domain, the drier sub-domains are given priority in the selection of a suitable convective scheme, albeit with a compromise for both rainfall and temperature simulations. The most suitable option Grell over Land and Emanuel over Ocean in wet (GLEO wet) delivers a rainfall wet bias of 2.96 % and a temperature cold bias of 0.26 °C, compared to CRU data. An ensemble derived from all 12 runs provides unsatisfactory results for rainfall (28.92 %) and temperature (-0.54 °C) bias in the drier region because some options highly overestimate rainfall (reaching up to 200 %) and underestimate

  3. Anomalies, sphalerons and baryon number violation in electro-weak theory

    1989-01-01

    In series of three lectures, baryon number violation at high temperatures in the Weinberg-Salam model is discussed. The first lecture presents a discussion of anomalies, and how this is related to level crossing of energy levels in the Dirac equation for fermions in an external field. The second lecture discusses topological aspects of the Weinberg-Salam theory, and some related two dimensional models. The sphaleron solution of these theories is constructed. In the final lecture, the sphaleron is related to transition rates at finite temperature. In a simple quantum mechanics model, it is shown that sphalerons, not instantons, are responsible for transitions at high temperature. The sphaleron induced rate is then discussed in a solvable 1+1 dimensional model, which has many similarities to the Weinberg-Salam model. Finally, the result for the Weinberg-Salam model is derived and is shown to be large for temperatures T ≥ 1 TeV. 35 refs., 9 figs. (author)

In addition, it is considered one of the most efficient ways to disseminate theories, ideas, and facts. Many critics feel that lectures are an obsolete method to use when students need to perform hands-on activities, which is an everyday need in the study of medicine. This study evaluates students' perceptions regarding lecture quality in a new medical school. Methods: This was a cross-sectional study conducted of the medical students of Universiti Sultan Zainal Abidin. The study population was 468 preclinical medical students from years 1 and 2 of academic year 2012–2013. Data were collected using a validated instrument. There were six different sections of questions using a 5-point Likert scale. The data were then compiled and analyzed, using SPSS version 20. Results: The response rate was 73%. Among 341 respondents, 30% were male and 70% were female. Eighty-five percent of respondents agree or strongly agree that the lectures had met the criteria with regard to organization of lecture materials. Similarly, 97% of students agree or strongly agree that lecturers maintained adequate voices and gestures. Conclusion: Medical students are quite satisfied with the lecture classes and the lectures. However, further research is required to identify student-centered teaching and learning methods to promote active learning. Keywords: lecture, effectiveness, evaluation, undergraduate medical

    An elementary introduction to unified gauge theories of electromagnetic and weak interactions is presented. The Goldstone theorem and the Higgs mechanism are discussed. The Weinberg-Salam model as well as the Georgi-Glashow ones are explained in details. One emphasizes on the experimental consequences of the Weinberg-Salam model (neutral current) [fr

  7. Analysis of the right-handed Majorana neutrino mass in an S U (4 )×S U (2 )L×S U (2 )R Pati-Salam model with democratic texture

    Yang, Masaki J. S.

    2017-03-01

    In this paper, we attempt to build a unified model with the democratic texture, that has some unification between up-type Yukawa interactions Yν and Yu . Since the S3 L×S3 R flavor symmetry is chiral, the unified gauge group is assumed to be Pati-Salam type S U (4 )c×S U (2 )L×S U (2 )R. The breaking scheme of the flavor symmetry is considered to be S3 L×S3 R→S2 L×S2 R→0 . In this picture, the four-zero texture is desirable for realistic masses and mixings. This texture is realized by a specific representation for the second breaking of the S3 L×S3 R flavor symmetry. Assuming only renormalizable Yukawa interactions, type-I seesaw mechanism, and neglecting C P phases for simplicity, the right-handed neutrino mass matrix MR can be reconstructed from low energy input values. Numerical analysis shows that the texture of MR basically behaves like the "waterfall texture." Since MR tends to be the "cascade texture" in the democratic texture approach, a model with type-I seesaw and up-type Yukawa unification Yν≃Yu basically requires fine-tunings between parameters. Therefore, it seems to be more realistic to consider universal waterfall textures for both Yf and MR, e.g., by the radiative mass generation or the Froggatt-Nielsen mechanism. Moreover, analysis of eigenvalues shows that the lightest mass eigenvalue MR 1 is too light to achieve successful thermal leptogenesis. Although the resonant leptogenesis might be possible, it also requires fine-tunings of parameters.

    We analyse symmetry breaking in the Weinberg-Salam model paying particular attention to the underlying geometry of the theory. In this context we find two natural metrics upon the vacuum manifold: an isotropic metric associated with the scalar sector, and a squashed metric associated with the gauge sector. Physically, the interplay between these metrics gives rise to many of the non-perturbative features of Weinberg-Salam theory. (author)

    The 6-dimensional geometric theory combining the general relativity theory with the model of electroweak Weinberg-Salam interactions is suggested. The metric process of charged W ± -boson introduction when giving up the condition of metrics cylindricity according to additional coordinates is used. Mass mechanism of the Higgs type leads to correct relation between W ± - and Z-bozon masses. Total correspondence with the Weinberg-Salam model is shown. The value of the Weinberg angle is found theoretically

    Full Text Available Recently many kinds of youth and students’ moral-character issues becomes a concern in Indonesia. To cope with these problems, Ministry of Education and Culture called for the implementation of Kurikulum 2013 (the national education curriculum. One of the curriculum characteristics is the religious competency to achieve in every school subjects including Biology. This research is aimed to evaluate implementation of Kurikulum 2013 in developing students’ religious attitude through Biology class in MAN 3 Malang. The field research with qualitative approach and descriptive design found that: first, the development of students’ religious competency is managed by teacher by formulating religious competency objective and accustoming salam and praying before the class begins; second, in the process of instruction, the teacher develop religious competency in four ways: salam and praying at introduction, finding relationship between Biology to Islamic teaching, salam and praying kafaratul majlis in closing the class, and admonishing students breaking the rules; last, this attitude development is constrained by the absence of evaluation guide.

  18. P-odd effects in the e-d scattering in the vector-like theories

    P-odd effects in elastic electron-deuteron scattering, due to the weak neutral currents, are analyzed in the framework of the vector-like theories. Considered is the case of the most general form of the P-invariance breaking in the elastic e - d scattering amplitude in both the leptonic and hadronic vertices. It is found that in the vector-like theories the parity violation in the electro-deuteron elastic scattering is confined in the hadronic vertex, while in the Weinberg-Salam model it is confined in the leptonic vertex. In the vector-like theories the asymmetry in the scattering of longitudinally polarized electrons by nonpolarized deuterons depends on the electromagnetic and weak form factors of a deuteron, whereas in the Weinberg-Salam model it does not depend on the structure of the deuteron. In the Weinberg-Salam model the asymmetry is independent on the T-violating form factors of the deuteron, whereas such a dependence is present in the vector-like theories

    We make analyses of the parity-violating asymmetries of electron-deuteron and electron-proton deep inelastic scatterings including sea quark contribution and adopting three different kinds of parton distribution functions. Both results from electron-deuteron and from electron-proton scatterings coincide with the prediction of the Weinberg-Salam model. Our results are found to be insensitive to the difference among the three kinds of parton distribution functions. We also study the x-, y-, and sin 2 theta sub(w)-dependences of A/Q 2 in the Weinberg-Salam model. Experiments at higher y value will be useful for more precise determination of the Weinberg angle theta sub(w). (author)

    1985-01-01

    The self-mass of the W-boson is calculated using a gravitational modified Weinberg-Salam theory with an anomalous magnetic moment assumed to be variable. The self-mass is shown to be finite with Gsub(N)sup(-1/2) (Gsub(N) Newton's gravitational constant) as the cutoff parameter. But only certain values of the anomalous magnetic moment yield a correct order of magnitude. Lowest order of perturbation theory gives complex solutions for these magnetic moments. Nevertheless, additional terms of higher perturbation theory will modify the equation for the magnetic moment and possibly lead to the definite magnetic moment of the W-boson of the non-modified Weinberg-Salam theory.

  6. Towards exact solutions of the non-linear Heisenberg-Pauli-Weyl spinor equation

    International Nuclear Information System (INIS)

    Mielke, E.W.

    1980-03-01

    In ''color geometrodynamics'' fundamental spinor fields are assumed to obey a GL(2f,C) x GL(2c,C) gauge-invariant nonlinear spinor equation of the Heisenberg-Pauli-Weyl type. Quark confinement, assimilating a scheme of Salam and Strathdee, is (partially) mediated by the tensor ''gluons'' of strong gravity. This hypothesis is incorporated into the model by considering the nonlinear Dirac equation in a curved space-time of hadronic dimensions. Disregarding internal degrees of freedom, it is then feasible, for a particular background space-time, to obtain exact solutions of the spherical bound-state problem. Finally, these solutions are tentatively interpreted as droplet-type solitons and remarks on their interrelation with Wheeler's geon construction are made. (author)

    Garaud, J.

    2010-09-01

    In this dissertation, we analyze in detail the properties of new string-like solutions of the bosonic sector of the electroweak theory. The new solutions are current carrying generalizations of embedded Abrikosov-Nielsen-Olesen vortices. We were also able to reproduce all previously known features of vortices in the electroweak theory. Generically vortices are current carrying. They are made of a compact conducting core of charged W bosons surrounded by a nonlinear superposition of Z and Higgs field. Far away from the core, the solution is described by purely electromagnetic Biot and Savart field. Solutions exist for generic parameter values including experimental values of the coupling constants. We show that the current whose typical scale is the billion of Amperes can be arbitrarily large. In the second part the linear stability with respect to generic perturbations is studied. The fluctuation spectrum is qualitatively investigated. When negative modes are detected, they are explicitly constructed and their dispersion relation is determined. Most of the unstable modes can be eliminated by imposing periodic boundary conditions along the vortex. However there remains a unique negative mode which is homogeneous. This mode can probably be eliminated by curvature effects if a small piece of vortex is bent into a loop, stabilized against contraction by the electric current. (author)

    Full Text Available In this work, the influence of native starter cultures on the microbiological, physicochemical and sensorial characteristics of Milano salami type was studied. Two batches of Milano salami type were produced: Batch A, with the addition of Staphylococcus xylosus U5 and Batch B (control without the starter culture. The Milano salami type was characterized by an important microbial activity of coagulase-negative staphylococci (CNS that resulted in substantial growth in Batch A during the ripening with an initial count of 7.60 log cfu.g-1 and reached 9.84 log CFU.g-1 after 14 days. Bacterial enzymes that showed efficient activity under the conditions found in Milano salami type were catalase, nitrite and nitrate reductase, contributing for sensory and physicochemical properties of the product. There were no significant differences in general free fatty acids composition among the batches, while the color parameters (L *, a * and b * in the Batch A presented significantly higher values in relation to Batch B. Moreover, batch A had the higher preference in sensorial analysis.A análise da influência de culturas iniciadoras nativas nas características microbiológicas, físicoquímicas e sensoriais de salame tipo Milano foi o objeto deste estudo.

Networking in nuclear education and training is covered in short articles on the World Nuclear University Summer Institute 2007, held in the Republic of Korea (14 July-24 August 2007), the 2007 School of Nuclear Knowledge Management, jointly organized by the IAEA, the Abdus Salam International Centre for Theoretical Physics (ICTP), Trieste, Italy and the Wold Nuclear University (WNU), and the Asian Network for Education in Nuclear Technology (ANENT), which is developing a web-based education and training system in the region. The 'News from INIS' (International Nuclear Information System) section of the newsletter highlights support for activities in IAEA Member States, in particular Egypt, Uzbekistan and Qatar. A partnership with the International Centre for Scientific and Technical Information (ICSTI), an INIS member, supported an International Seminar on Scientific and Technological Innovation, held in Vienna in May 2007. The newsletter reports about this meeting and a plan for future cooperation between the IAEA and ICSTI. Other INIS-related articles refer to updating the radioisotope terminology of the ETDE/INIS Joint Thesaurus, adding new descriptors and their associated terms, as well as a report on progress in the digital preservation of INIS non-conventional literature from microfiche to digital media. Microfiche collections of several IAEA Member States (Canada, China and India) were digitized and the Serbian knowledge preservation project on the RA type reactor was successfully completed. Internally, IAEA policy documents and technical reports kept at the IAEA Library have been or are being turned into digital format. For the first time, this newsletter specifically reports about news from INIS Members, including an INIS training seminar in Slovakia, which is part of Comenius University's bachelor programme in chemistry

  13. Supersymmetric quantum mechanics, spinors and the standard model

    International Nuclear Information System (INIS)

    Woit, P.

    1988-01-01

    The quantization of the simplest supersymmetric quantum mechanical theory of a free fermion on a riemannian manifold requires the introduction of a complex structure on the tangent space. In 4 dimensions, the subgroup of the group of frame rotations that preserves the complex structure is SU(2) x U(1), and it is argued that this symmetry can be consistently interpreted to be an internal gauge symmetry for the analytically continued theory in Minkowski space. The states of the theory carry the quantum numbers of a generation of leptons in the Weinberg-Salam model. Examination of the geometry of spinors in four dimensions also provides a natural SU(3) symmetry and very simple construction of a multiplet with the standard model quantum numbers. (orig.)

  14. New ideas about unified field theory

    1986-01-01

    An outline of the physical concepts evolution is given from the ancient philosophers to the present time. With qualitative explanations about the meaning of the theories that is the milestones of these concepts evolution, it mentions the ideas which lead the studies to the conception of a unified field theory. Chronologically, it has brief information about the ideas of Laplace (mechanical determinism), Maxwell (the field concept), Einsten (the space-time structure), Heisenberg and Schroedinger (the quantum mechanics), Dirac (the relativistic quantum and the antiparticles), Gell-Mann (the quarks), Weinberg-Salam (Weak interactions and eletromagnetic unification), H. Georgi and S. Glashon (strong interactions plus Weinberg-Salam), Kaluza-Klein (a fifth space-time coordinate), and Zumino-Weiss (supersymmetry and supergravity). (G.D.F.) [pt

  15. Weak effects in the decay spectra of neutral pseudoscalar mesons

    International Nuclear Information System (INIS)

    Ragutt, B.; Schuelke, L.

    1978-01-01

    The effect of the neutral weak current on the decay mode of a neutral pseudoscalar meson (πsup(deg) or eta) into a photon and a lepton-antilepton pair has been calculated within the framework of the Weinberg-Salam model. A parity-violating contribution to the decay spectrum is found to be larger for the decay eta→γμ + μ - . In this case it can be of the order 10 -6 strongly depending on the value of the Weinberg angle and thus is still beyond the present experimental possibilities. However, a measurement of this effect would not only give a strong hint on the value of the Weinberg angle, but could also help to resolve the difficulties of the Weinberg-Salam model in atomic-physics experiments

  16. Comments on a novel approach to the role of chirality in the origin of life

    International Nuclear Information System (INIS)

    Chela-Flores, J.

    1991-06-01

    We review a recent paper (Salam, 1991a) in which a specific enhancement factor (i.e., a phase transition into a condensed Bose mode) is proposed to account for the observed amplification of the ground state energies of the L- and D-amino acid enantiomers; the difference between these energies is assumed to be due to the neutral parity-violating electroweak interaction. This physical effect initially shifts the enantiomer energies by about 3 x 10 -19 eV. The proposed phase transition is characterized by a critical temperature T c , which may be studied theoretically by enlarging the standard electroweak theory to include either the top quark or supersymmetry (Salam, 1991b). Possible experimental means of finding T c are discussed. (author). 24 refs, 1 fig

  18. Post-sphaleron baryogenesis and n- anti n oscillation in non-SUSY SO(10) GUT with gauge coupling unification

    International Nuclear Information System (INIS)

    Patra, Sudhanwa; Pritimita, Prativa

    2014-01-01

    ''Post-sphaleron baryogenesis'', a fresh and profound mechanism of baryogenesis accounts for the matter-antimatter asymmetry of our present universe in a framework of Pati-Salam symmetry. We attempt here to embed this mechanism in a non-SUSY SO(10) grand unified theory by reviving a novel symmetry breaking chain with Pati-Salam symmetry as an intermediate symmetry breaking step and as well to address post-sphaleron baryogenesis and neutron-antineutron oscillation in a rational manner. The Pati-Salam symmetry based on the gauge group SU(2) L x SU(2) R x SU(4) C is realized in our model at 10 5 -10 6 GeV and the mixing time for the neutron-antineutron oscillation process having ΔB = 2 is found to be τ n- anti n ≅ 10 8 -10 10 s with the model parameters, which is within the reach of forthcoming experiments. Other novel features of the model include low scale right-handed W R ± , Z R gauge bosons, explanation for neutrino oscillation data via the gauged inverse (or extended) seesaw mechanism and most importantly TeV scale color sextet scalar particles responsible for an observable n- anti n oscillation which may be accessible to LHC. We also look after gauge coupling unification and an estimation of the proton lifetime with and without the addition of color sextet scalars. (orig.)

  19. Supersymmetric SO(10) models inspired by deconstruction

    International Nuclear Information System (INIS)

    Huang Chaoshang; Jiang Jing; Li Tianjun

    2004-01-01

    We consider 4-dimensional N=1 supersymmetric SO(10) models inspired by deconstruction of 5-dimensional N=1 supersymmetric orbifold SO(10) models and high-dimensional non-supersymmetric SO(10) models with Wilson line gauge symmetry breaking. We discuss the SO(10)xSO(10) models with bi-fundamental link fields where the gauge symmetry can be broken down to the Pati-Salam, SU(5)xU(1), flipped SU(5)xU(1)' or the Standard Model like gauge symmetry. We also propose an SO(10)xSO(6)xSO(4) model with bi-fundamental link fields where the gauge symmetry is broken down to the Pati-Salam gauge symmetry, and an SO(10)xSO(10) model with bi-spinor link fields where the gauge symmetry is broken down to the flipped SU(5)xU(1)' gauge symmetry. In these two models, the Pati-Salam and flipped SU(5)xU(1)' gauge symmetry can be further broken down to the Standard Model gauge symmetry, the doublet-triplet splittings can be obtained by the missing partner mechanism, and the proton decay problem can be solved. We also study the gauge coupling unification. We briefly comment on the interesting variation models with gauge groups SO(10)xSO(6) and SO(10)xflippedSU(5)xU(1)' in which the proton decay problem can be solved

    Full Text Available The aim of this study was to determine the nutritional composition (moisture, protein, carbohydrates, and total fat of some meat products produced in the northeastern Argentina, analyzing fatty acids composition, polyunsaturated/saturated fatty acid ratio PUFA/SFA ratio (polyunsaturated/ saturated fatty acids, n-6/n-3 ratio, and CLA (conjugated linoleic acid content. Thirty traditional meat products produced by different processes were used. The samples were classified into 4 different categories as follows: salamín (dry cured and fermented sausage, chorizos (raw sausage, chorizo ahumado (cooked and smoked sausage, and morcilla (cooked sausage. From the results obtained it can be said that the total carbohydrate contents of the salamín studied were slightly lower; fat content of raw chorizo was significantly lower, and protein content of chorizo ahumado was significantly higher than those comparison from databases from other regions of Argentina, USA, and Spain. Except for chorizo, which has a value lower than 0.4, the PUFA/SFA-stearic ratio of the other products were a little higher than those reported by other researchers. CLA (Conjugated linoleic acid contents between 0.03% and 0.19% were detected. The results obtained indicate that salamín produced in northeastern Argentina, Chaco state, shows high protein and PUFA (Polyunsaturated fatty acids contents, and low atherogenic and thrombogenic indexes, which makes it a more healthful product than those of similar composition produced in other countries.

  5. Parity violation in deep inelastic electron scattering

    International Nuclear Information System (INIS)

    Taylor, R.E.

    1979-11-01

    Neutral currents in electron scattering and the Weinberg-Salam model are reviewed. This generally accepted model is consistent with experimental results from neutrino interactions; an appropriate deep inelastic electron scattering experiment would measure couplings that don't involve neutrinos to see if they are also correctly described by the theory. The SLAC-Yale experiment measures a difference in the e-d inelastic cross section for right- and left-handed electrons. The polarized source, beam monitors, scattering experiment, checks of helicity dependence, and results are described. It is concluded that the data obtained are in agreement with the Weinberg-Salam model, and that the best value of sin 2 theta/sub W/ for these data is in excellent agreement with the average values of that parameter deduced from neutrino experiments. Future experiments with polarized electrons are discussed. 12 figures, 2 tables

    we had an unforgettable experience producing paper sheets ourselves in an old but still operational paper mill in the green enchanting spa of Duszniki Zdrój. A short intensive course in pottery handcraft was also offered to us in the Skansen. Hiking in the rocky labyrinth of Szczeliniec (please try to pronounce this name describing a magnificent cliffed hill with creviced rocks) was also a great adventure. This was followed by a ride on the serpentine Road of a Hundred Turns. And there was another event strongly supported by the local authorities. Two special tutorials on energy research and fusion for young scholars and the general public attracted nearly 200 people. The School was financially supported by the International Centre for Dense Magnetised Plasmas at IPPLM, European Commission, International Atomic Energy Agency, Vienna (Austria), the Abdus Salam International Centre for Theoretical Physics, Trieste (Italy) and the US Department of Energy. We would like to thank cordially our sponsors. Their financial support made it possible for a number of students and teachers to come to Kudowa Zdrój. We are very grateful to Dr Adam Ziembinski, the director of the spa in Kudowa, and his staff for the immense hospitality during our stay. We wish to thank Mr Czeslaw Krecichwost, the mayor of Kudowa Zdrój, for his strong support and interest in the School and help in organizing the lectures for scholars and residents of the region. And our most cordial thanks and gratitude go to Mr Ryszard Panfil for his great kindness, inexhaustible energy and organizational efficiency that helped all of us to enjoy the meeting. We thank all the participants for their contributions and we thank the reviewers of all submitted papers. Thank you for your hard work and co-operation. We are looking forward to the next school and all hope to meet again in Kudowa.

    The Project "MAR VASTO" ("Risk Management in Valparaíso/Manejo de Riesgos en Valparaíso, Servicios Técnicos", 2007) started in March 2007, with coordination of ENEA (Italian Agency for New Technologies, Energy and Environment), participation of several partners (Italy: University of Ferrara, Faculties of Architecture and Engineering; University of Padua, Faculty of Engineering; Abdus Salam International Centre for Theoretical Physics of Trieste; Chile: Valparaíso Technical University Federico Santa Maria, Civil Works Department; Santiago University of Chile, Division Structures Constructions Geotechnics), and support of local stakeholders. Being Valparaíso included since 2003 in the UNESCO Word Heritage List of protected sites, the project main goals are the following: to collect, analyze and elaborate the existing information, with a satisfying evaluation of main hazards; to develop a GIS digital archive, well organized, user-friendly and easy to be implemented in the future, providing maps and scenarios of specific and multiple risk; to provide a vulnerability analysis for three historical churches (San Francisco del Baron, Las Hermanitas de la Providencia, La Matríz, made by various materials - masonry, concrete, wood and adobe - and located in different city sites) and for a building stock in the Cerro Cordillera (partially inside the UNESCO area), analyzing more than 200 constructions; to suggest guidelines for future urban planning and strengthening interventions. In the framework of the MAR VASTO Project, the most important hazards have been investigated carried out. With regard to seismic hazard, "state-of-the-art" information has been provided by Chilean partners and stakeholders, using materials of several studies and stored in original earthquake reports, local newspapers and magazines. The activities performed by the Italian team regarded the definition, for the city of Valparaiso, of earthquake scenarios and maps based on the neo

    to his schoolteacher's expectations he later graduated (with honors) from Agra University at the age of 17 and then proceeded to obtain his PhD in physics from the Hindu Banaras University, at the age of 21. He then proceeded to the University of Umeå, Sweden, on scholarship, and quickly blossomed to his full potential under the caring guidance of Prof. Lennart Stenflo, while also earning his second PhD, three years later. These early experiences deeply influenced Padma; on the one hand he recognizes that raw talent exists in all corners of the world, and on the other hand he feels a deep commitment to help discover, nurture, and mentor such talent. Toward this end Padma did several things. He organized numerous international meetings in both developed and developing nations. He has also continued to organize the annual Plasma Physics Summer School at the Abdus Salam International Center for Theoretical Physics in Trieste, Italy. He has used these opportunities to discover promising young scientists from the world over, helping them to come to his host university in Bochum, with support obtained from various international organizations, and mentored them. These young scholars, haling from every continent of the world, have gone on to become active scientists in their own right and many have proceeded to become leading researchers, educators, and administrators in their home countries. It is in recognition of his “extraordinary efforts in the discovery, the nurturing and mentoring of scientific talent across the globe” that he received the highly prestigious Nicholson Medal, awarded by the American Physical Society, for human outreach by a leading scientist in 2005. In recognition of his outstanding scientific contributions Padma has received numerous international honors including several honorary doctorates, foreign membership of several national academies, fellowships of a number of international scientific organizations and prizes.

  4. The origin of chirality in protein amino acids

    International Nuclear Information System (INIS)

    Chela Flores, J.

    1994-03-01

    We discuss the origin of the chirality of protein amino acids from the point of view of a phase transition from a racemic mixture into an optically pure state. We assume that Bose-Einstein condensation may act as an amplification mechanism. The originals theory is due to Salam. We suggest a new role for the phase transition. Following Quack we distinguish parity violation of two kinds (de facto and de lege symmetry breaking). While the Salam phase transition corresponds to parity violation of the second kind (de lege), the phase transition we discuss in this work corresponds to parity violation of what we may call a third kind. This is suggested by recent experimental phenomena which correlate chiral symmetry breaking and pattern formation (spontaneous symmetry breaking that separates an initial racemic mixture into right- and left-handed space domains by means of a substrate). Tentative comments are given on the eventual design of possible experiments that may test this new hypothesis. (author). Refs

  16. Nuclear fuel cycle: international market, international constraints and international cooperation

    International Nuclear Information System (INIS)

    Imai, R.

    1977-01-01

    Some of the constraints on the nuclear fuel cycle are ones arising from economic and financial reasons, those caused by uranium resources and their distribution, those arising from technical reasons, issues of public acceptance, and those quite independent of normal industrial considerations, but caused by elements of international politics. The nuclear fuel cycle and the international market, matters of nuclear non-proliferation, and international cooperation are discussed

    2014-01-01

    Full Text Available Analysis and studying of the terrorism in all its facets is a complex entangled problem with less clear legal regulation that it might seem at first glance, especially after its transformation from local phenomenon into a world threat. Hitherto terrorism and actions connected to it have been criminalized by the majority of states. There are in modern criminal law whole systems of rules on criminal liability for terrorism which differs considerably from country to country. Terrorism has been criminalized in numerous international regional and universal antiterrorist legal instruments. The author notes that differences in definitions that are enshrined in them hinders international cooperation in criminal matters with respect to terrorist cases. Difficulties reside in the necessity to meet the dual criminality requirement and in the political offense exception. These difficulties can only be overcome through elaboration of a universally recognized definition of the notion of international terrorism and making it legally binding via its inclusion into a universal convention. The issue of definition of international terrorism is an important part of an efficient mutual assistance among states in fight against this crime. In this article the author accounts of actual ways of tackling by the international community of the issue of criminalization of international terrorism and of factors influencing them.

    Gauge theories with massless or massive fermions in a selfcontragredient representation exhibit global symmetries of Pauli-Guersey type. Some of them are broken spontaneously leading to a difermion Goldstone bosons. An example of a boson version of the Pauli-Guersey symmetry is provided by the Weinberg-Salam model in the limit THETAsub(w)→O

  3. From Schawlow to Newton: An educational return

    Science.gov (United States)

    Sathe, D.

    Newton's laws of motion and his theory of gravitation are known for over 300 years. However, investigations of educators, from various countries and carried out in the last quarter of the 20t h century, show that the Aristotelian ideas keep persisting among students - in spite of learning thes e topics in schools and colleges. In the traditional examinations students do give answers in accordance with Newton's laws but in questionnaires of educators they ignore Newtonian laws unknowingly, and quite naturally give answers along the Aristotelian line of thought. Why do they give such contrasting answers? Should we take for granted that their understanding of Newtonian laws is satisfactory because of their correct answers in traditional exams, though not in questionnaires? Can these contrasting views affect their interest in physics? These are some questions that warrant our attention earnestly, as we gear up for the research and teaching in 21s t century. The author felt the need of focusing attention on the logical aspects of the subject, due to the global character of said problem. His decision was strengthened greatly, in late1970s, by the philosophy of Dennis Sciama and hence author's dedication of a letter to the editor to his memory, in the COSPAR Info. Bulletin /1/. Being a trained biochemist, author started looking for points, missed by the earlier educators - that means author started following the advice of Arthur Schawlow /2/ in late 1970s, though unknowingly. Sadly, author came to know of it after dedicating a lecture to the memory of Abdus Salam in a symposium in Samarkand, Uzbekistan. Therefore he is dedicating this presentation to the memory of Arthur Schawlow. According to the present author, the persistence of Aristotelian ideas and consequent contrasting performances of students are due to the logical conflicts between the basic concepts of physics itself. For example, the conflict between the treatment of uniform circular motion and the concept of

    Azimov, Ya.I.; Khoze, V.A.

    1979-01-01

    Experimental results which proved the reality of quarks are reviewed along with further experiments broadening the representation of quarks and leptons and providing the basis to develop the theory of elementary particles. The discovery of the J/psi particle is noted to give rise to the discovery of c-quark, the existance of which is confirmed by the discovery of charmed hadrons. The main aspects of quantum chromodynamics explaining the mechanism of strong interaction of quarks are considered along with those of the Weinberg-Salam theory proposed to describe weak and electromagnetic interactions of quarks and leptons. Experimental data testifying to the existance of heavy tausup(+-) leptons are presented. The history of discovery of γ mesons and of a new heavier b-quark is described. Perspectives for studying elementary particles are discussed. Further studies of γ mesons, discovery and investigation of charmed particles are noted to be immediate tasks along with the search for manifestation of t-quark considered to be a partner of b-quark from the viewpoint of the Weinberg-Salam model

  5. Exophobic Quasi-Realistic Heterotic String Vacua

    CERN Document Server

    Assel, Benjamin; Faraggi, Alon E; Kounnas, Costas; Rizos, John

    2009-01-01

    We demonstrate the existence of heterotic-string vacua that are free of massless exotic fields. The need to break the non-Abelian GUT symmetries in k=1 heterotic-string models by Wilson lines, while preserving the GUT embedding of the weak-hypercharge and the GUT prediction sin^2\\theta_w(M(GUT))=3/8, necessarily implies that the models contain states with fractional electric charge. Such states are severely restricted by observations, and must be confined or sufficiently massive and diluted. We construct the first quasi-realistic heterotic-string models in which the exotic states do not appear in the massless spectrum, and only exist, as they must, in the massive spectrum. The SO(10) GUT symmetry is broken to the Pati-Salam subgroup. Our PS heterotic-string models contain adequate Higgs representations to break the GUT and electroweak symmetry, as well as colour Higgs triplets that can be used for the missing partner mechanism. By statistically sampling the space of Pati-Salam vacua we demonstrate the abundan...

He was senior research investigator at the Blackett Laboratory and Emeritus Professor of Theoretical Physics at Imperial College, London. He made seminal contributions to our current understanding of symmetries and symmetry breaking in the Standard Model of particle physics. He was among those who, in 1964, proposed the mechanism of spontaneous symmetry breaking in gauge theories, together with G. Guralnik and C. Hagen in the autumn of that year, following the papers by R. Brout and F. Englert and by P. Higgs. When this new understanding was incorporated into a model proposed by S. Glashow in 1961, it led to the first formulations of the Standard Model by S. Weinberg and A. Salam. Kibble deepened our under...

    Electron antineutrino-electron scattering is modified in the presence of neutrino mixing and neutrino oscillation. In the Weinberg-Salam model the results for reactor antineutrinos are insensitive to the degree of mixing, to the extent that the experiment of Reines, Gurr and Sobel cannot differentiate between no oscillation and complete disappearance of the electron antineutrinos from the beam

    A six quark model is discussed for the weak interactions of hadrons in which parity is violated spontaneously in an SU(2) x U(1) gauge theory. Quarks with very small masses are required and their weak interactions approximate those of the Weinberg-Salam model. Suppression of strangeness-changing neutral currents requires at least seven quarks. (author)

The practice of states within international organizations such as the UN General Assembly, for example, may contribute to the development of custom. Yet, there is little...... discussion about whether and how the practice of international organizations as such may contribute to the development of customary international law. This contribution discusses the organization that is the most capable of contributing to the development of customary international law in its own right...

    2010-05-01

    Full Text Available The emergence of international environmental law has produced important challenges to the very foundations of public international law. Traditional concepts such as state sovereignty, subjects of international law, and the early perspectives of national security are being transformed. The needs of the contemporary international society differ from the ones of the Wesphalian conception, situations which clearly explains the raise of alternative views for the understanding of the current dynamics of international law, where concepts like res communis, common concerns and simply “commons” take a privileged place in the study of international law. The foregoing has been strengthened by the international development of the so called erga ommnes obligations, label which is being used by international environmental law as the perfect explanation of its own existence. This academic article presents and studies the abovementioned concepts trying to compare what international law used to be before the emergence of international environmental law and what it is and what it should be in order to attend the developments and challenges imposed by the contemporary international society, particularly by international environmental law, a new fi eld of the corpus juris of public international law.

    2008-10-01

    mixing dynamics are interplayed with fundamental properties of the Euler and compressible Navier-Stokes equations, with the problem sensitivity to the initial conditions and to the boundary conditions at the discontinuities, and with its stochastic description. The state-of-the-art numerical simulations of the multi-phase non-equilibrium dynamics suggest new methods for capturing discontinuities and singularities and shock-interface interaction, for predictive modeling of the multi-scale dynamics in fluids and plasmas, for error estimate and uncertainty quantification as well as for novel data assimilation techniques. The First International Conference `Turbulent Mixing and Beyond' (TMB-2007), was held on 18-26 August 2007 at the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy. This was a highly informative and exciting meeting, by all the standards a major success. The Conference brought together 120 participants (307 authors) from five continents, ranging from students to members of National Academies of Sciences and Engineering and including researchers from the Universities, National Laboratories, Leading Scientific Institutions and Industry. TMB-2007 covered 16 different topics, maintaining the scope and the interdisciplinary character of the meeting, and kept the focus on a fundamental fluid dynamic problem of unsteady turbulent processes and the Conference Objectives. The success of the TMB-07 was a result of the successful work of all the participants, who were serious and professional people, caring for the quality of their research and sharing their scientific vision. The level of presentations was high, and the presentations included 87 oral contributions, 32 invited lectures and 5 tutorials and over 30 poster contributions. The round table discussions held at TMB-2007 investigated the organization of a Collaborative Computing Environment for the Turbulent Mixing and Beyond Community.

  4. REFLECTIONS ON PRODUCTION INTERNALIZATION AND ITS INTERNATIONAL TRADE IMPLICATIONS

    Directory of Open Access Journals (Sweden)

    CLIPA RALUCA IRINA

    2014-06-01

    Full Text Available Vertically-integrated multinational companies place the different stages of production and marketing chain in different countries, looking for advantages such as low production costs, lower taxes, abundant resources and so on, while benefiting from the advantages of economies of scale, control of supplies or outlets. In fact, this vertical integration of multinational companies has led to the expansion of intra-firm trade and "internalized" operations, thus creating their own markets for the vertically-integrated production. Internationally active firms operate in a way that replaces the different functions of an open market with internal transactions, i.e. intra-firm transactions, whenever internal transaction costs are lower than the open-market ones. The direct consequence over international trade is the increase of intra-firm share of trade flows to one third of world trade, those companies making a suppression of international market segments that act in favour of an internal market. The creation of a multinational market and the enhancement of intra-firm trade have profound quantitative and qualitative implications on the composition, geographic orientation and dynamics of international trade. This paper deals with the issue of production internalization, with an overview of the main contributions made to the theory of internalization, while tackling its relative dimension. However, we intend to highlight the implications of this phenomenon on international trade. The work methodology falls within the range of qualitative approaches: logical argumentation, critical theoretical analysis.

    The internalization of nanoparticles into cells is critical for effective nanoparticle mediated drug delivery. To investigate the kinetics and mechanism of internalization of nanoparticles into cells we have developed a DNA molecular sensor, termed the Specific Hybridization Internalization Probe - SHIP. Self-assembling polymeric 'pHlexi' nanoparticles were functionalized with a Fluorescent Internalization Probe (FIP) and the interactions with two different cell lines (3T3 and CEM cells) were studied. The kinetics of internalization were quantified and chemical inhibitors that inhibited energy dependent endocytosis (sodium azide), dynamin dependent endocytosis (Dyngo-4a) and macropinocytosis (5-(N-ethyl-N-isopropyl) amiloride (EIPA)) were used to study the mechanism of internalization. Nanoparticle internalization kinetics were significantly faster in 3T3 cells than CEM cells. We have shown that ~90% of the nanoparticles associated with 3T3 cells were internalized, compared to only 20% of the nanoparticles associated with CEM cells. Nanoparticle uptake was via a dynamin-dependent pathway, and the nanoparticles were trafficked to lysosomal compartments once internalized. SHIP is able to distinguish between nanoparticles that are associated on the outer cell membrane from nanoparticles that are internalized. This study demonstrates the assay can be used to probe the kinetics of nanoparticle internalization and the mechanisms by which the nanoparticles are taken up by cells. This information is fundamental for engineering more effective nanoparticle delivery systems. The SHIP assay is a simple and a high-throughput technique that could have wide application in therapeutic delivery research.

    Full Text Available The international criminal justice has experienced a rapid change over the past years. This circumstance has underscored the need for interaction and complementation between international and domestic law. Some authors consider that the international criminal justice, and the activities of its tribunals, jeopardize the legality of international law. Our vision is that international criminal justice is a central pillar of the rule of law, at the national and the international levels. Far from undermining the legality of international law, international criminal justice paves the way towards a true international public order.

This internal marketing studyinvolves variables of motivation and reward system, effective communication, effective employee's selection, effective recruitment, effective development, effective support system, and healthy work environment. While the internal quality service aspects that will be examined in this study are: tangible, emphaty, responsiveness, reliability and assurance, and then their influences on internal customer satisfaction would be analyzed.The sample size is 210 respondents,which is determined using purposive sampling method. The main instrument for data collection in this study is through questionnaire. The analysis tool used to examine the hypothesis of the study is Structural Equation Modeling using AMOS Version 20.0 Software. The result of the study shows that: Internal marketing and internal quality service significantly influence internal customers satisfation. However, the internal quality service influence the internal customers satisfaction more significantly. Therefore the managers in tourism industry should improve the internal marketing more than the internal quality service.

    Burova, M.V.; Ter-Martirosyan, K.E.

    1988-01-01

    A left-right (L-R) symmetric model of four-dimensional supergravitation with a SO(10) gauge group obtained as the low-energy limit is superstring theory is considered. The spectrum of the gauge fields and their interactions are in agreement with the Weinberg-Salam theory. In addition, the model includes heavy W R ± and Z μ ' bosons. Beside the N g =3 generations of the 16-plets the SO(10) model includes the fragments of such generations which play the role of Higgs particles and also scalar chiral filds, the number of which exceeds by one the number of generations. As a result the neutrinos of each generation obtain a stable small Majorana mass. It is shown that the scalar field potential leads to spontaneous violation of the SU(2) R group and L-R symmetry and at low energies the standard Weinberg-Salam theory appears. However, reasonable values of X bosons masses M x and sun 2 Θ W (Θ W is the Weinberg angle) can be obtained in the model only in the case of high mass scale M R ∼10 10 -10 12 GeV of the right group SU(2) R violation

  12. Search for the decay B^0_sarrow e μ at CDF

    1996-05-01

    We present a search for the decay B^0_sarrow e μ. This decay is strictly forbidden within the standard model of electroweak interaction. However, extensions to the standard model exist which predict a symmetry between quarks and leptons and one of the signals predicted by these models is the decay B^0_sarrow e μ. An example of such model is the Pati-Salam model. We present the first limit on Br(B^0_sarrow e μ). From this limit we derive a mass limit on the Pati-Salam leptoquark mass. ^ Supported by U.S. DOE DE-AC03-76SF00098. ^ Supported by U.S. DOE DE-AC02-76CHO3000. ^*We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

  13. Electro-weak theory

    1980-01-01

    By electro-weak theory is meant the unified field theory that describes both weak and electro-magnetic interactions. The development of a unified electro-weak theory is certainly the most dramatic achievement in theoretical physics to occur in the second half of this century. It puts weak interactions on the same sound theoretical footing as quantum elecrodynamics. Many theorists have contributed to this development, which culminated in the works of Glashow, Weinberg and Salam, who were jointly awarded the 1979 Nobel Prize in physics. Some of the important ideas that contributed to this development are the theory of beta decay formulated by Fermi, Parity violation suggested by Lee and Yang, and incorporated into immensely successful V-A theory of weak interactions by Sudarshan and Marshak. At the same time ideas of gauge invariance were applied to weak interaction by Schwinger, Bludman and Glashow. Weinberg and Salam then went one step further and wrote a theory that is renormalizable, i.e., all higher order corrections are finite, no mean feat for a quantum field theory. The theory had to await the development of the quark model of hadrons for its completion. A description of the electro-weak theory is given

    Since as early as 1964, a small group of agricultural scientists of the Bangladesh Atomic Research Establishment have been using radioisotopes and radiation tools in their research. Realizing the potential use of nuclear tools in agriculture, this agricultural section was reorganized and expanded into a full-fledge institute. For this work the need for outside support was foreseen and in July 1973 the Government submitted a request for support from the Swedish International Development Agency (SIDA). As a result, a technical assistance SIDA project was approved, with the IAEA being the executing agency. This US $1 million, 5 year-project provides for some 100 man-months of international expertise, some 200 man-months of fellowships, as well as for various equipment and supplies. The Institute of Nuclear Agriculture was formally inaugurated on 12 December 1977, by the Vice-President of the People's Republic of Bangladesh, Justice Abdus Sattar. Helio F.S. Bittencourt, the IAEA Deputy Director General for Technical Assistance and Publications, represented the Agency at this ceremony. The objectives of INA are: 1. To identify and solve basic agricultural problems of the country through inter-disciplinary approach, employing both nuclear and conventional research techniques. 2.

    A gauge model with eight quarks, on the basis of the SU(2)U(1) gauge group, containing the Weinberg-Salam-GIM model is proposed. It may explain the ratio of the neutral current and charged current found at Gargamelle and HPWF, the large y anomaly and, with a convenient introduction of the leptonic sector, the energetic trimuons observed recently in neutrino nucleon collisions

    A new mechanism is proposed for the mixing of Weinberg-Salam Higgs fields in superstring-inspired SO(10) models with no SO(10) singlet fields. The higher-dimensional terms in the superpotential can generate both Higgs field mixing and a small mass for the physical neutrino. I would like to thank Professor C.

Therefore, building on the two broad arguments of operating flexibility and location-specific commitment, we develop a theoretical framework that focuses on the extent to which a firm's international...... arbitrage strategy is characterized by specialization versus replication and argue that these different strategies may have differential impact on profitability and risk reduction.

    Full Text Available The modern international monetary system has a number of flaws and therefore needs cardinal change. Hence, economists from all over the world are suggesting alternative international currencies that would make the international monetary system more efficient. However, it is essential when approaching the creation of a new international currency to analyze and take into account the experience of all the past international currencies. Therefore this paper begins with an exploration of the drawbacks of each of the past and present international currencies. Drawing on this analysis a justification will be made for the necessity of introducing a new international currency, pointing to the requirements it should meet. Further on, this paper proposes an alternative theoretically possible variant of the international currency, with a fixed value relative to a commodity basket. An abstract example is used to demonstrate its composition and circulation mechanism.

    Full Text Available Envisioning an international public order means envisioning an order sustained by a legal and institutional framework that ensures effective collective action with a view to defending fundamental values of the international community and to solving common global problems, in line with the universalist vision of international law. Envisioning the construction of an international public order means considering that this framework, which embraces and promotes the respect for human rights focused particularly on human dignity, is consolidating and evolving based on the International Criminal Court (ICC. The establishment of the ICC added an international punitive perennial facet to international humanitarian law and international human rights law and linked justice to peace, to security and to the well-being of the world, reaffirming the principles and objectives of the Charter of the United Nations (UN. Nevertheless, the affirmation process of an international criminal justice by punishing those responsible for the most serious crimes of concern to the international community as a whole, faces numerous obstacles of political and normative character. This article identifies the central merits of the Rome Statute and ICC’s practice and indicates its limitations caused by underlying legal-political tensions and interpretive questions relating to the crime of aggression and crimes against humanity. Finally, the article argues for the indispensability of rethinking the jurisdiction of the ICC, defending the categorization of terrorism as an international crime, and of articulating its mission with the "responsibility to protect", which may contribute to the consolidation of the ICC and of international criminal law and reinforce its role in the construction of an effective international public order.

    International Nuclear Information System (INIS)

    Chatelet, G.; Paris-13 Univ., 93 - Saint-Denis

    1981-01-01

    We present here a survey of gauge theories, trying to relate the main mathematical and physical concepts. Part I is devoted to exhibiting parallel transport and connection as the adequate concepts for the constitution of the parametrized internal space of a particle. A covariant derivative provides the differential calculus, which is needed when one leaves the point-like description in microphysics. Part II deals with the so-called pure gauge theory and sketches the construction of the self-dual solutions of Yang-Mills equations. We briefly explain Guersey's method to get SU 2 self-dual potentials as quarternionic analytic maps from S 4 (first quarternionic projective space) into HPsub(n) (n-dimensional quarternionic projective space). Part III is devoted to the Goldstone's theorem and Higgs' mechanism used to provide a mass to gauge mesons. We describe a Salam-Weinberg model to illustrate these techniques. Part IV deals with the perturbative aspect. The Faddeev-Popov method, formerly conceived as a technique to get correct Feynmann rules, actually leads to a systematic study of the affine space of connections factored out by gauge transformations.

  13. International Responsibility and the Systemic Character of International Law

    Directory of Open Access Journals (Sweden)

    Saganek Przemysław

    2017-12-01

    Full Text Available The question whether international law is a system is one of the modern topics discussed by specialists of international law. The text of P. Saganek poses this question with respect to the rules on international responsibility. The two aims are to establish whether the rules on state responsibility are a system themselves and whether they may prima facie support the idea of international law as such a system. The two prima facie answers are positive. Every violation of international law gives rise to state responsibility if it can be attributed to a state and no circumstance precluding wrongfulness is in place. In this sense the rules on state responsibility form a sub-system supporting the thesis on the systemic nature of international law. On a closer analysis one can encounter several doubts as to both answers. Paradoxically those rules are too ideal, too systemic. The author – without denying the necessity of several if not the majority of the identified rules – refers to a tendency of presenting as law some non-binding documents prepared by expert groups. This is a part of a wider process of ‘paper-law’. In this sense expert groups engage in ‘creating the language’ in which the true subjects of international law are expected to speak.

This current is given by the gauged topological current plus a total divergence term. The total divergence term is absent in Weinberg-Salam theory with one scalar Higgs doublet, even for an arbitrary mass matrix, but appears when several Higgs doublets are present. (orig.)

How do you measure degrees of benevolence and compassion? If it is so obvious to our profession, what professionalism is, then why is it so difficult to teach it to medical students and residents? Today’s definition of medical professionalism is evolving – from autonomy to accountability, from expert opinion to evidence-based medicine, and from self-interest to teamwork and shared responsibility. However, medical professionalism is defined as the basis for the trust in the patient–physician relationship, caring and compassion, insight, openness, respect for patient dignity, confidentiality, autonomy, presence, altruism, and those qualities that lead to trust-competence, integrity, honesty, morality, and ethical conduct. The purpose of this study is to explore professionalism in terms of its fundamental elements among medical students of Universiti Sultan Zainal Abidin (UniSZA.

  8. Detailed examination of 'standard elementary particle theories' based on measurement with Tristan

    International Nuclear Information System (INIS)

    Kamae, Tsuneyoshi

    1989-01-01

    The report discusses possible approaches to detailed analysis of 'standard elementary particle theories' on the basis of measurements made with Tristan. The first section of the report addresses major elementary particles involved in the 'standard theories'. The nature of the gauge particles, leptons, quarks and Higgs particle are briefly outlined. The Higgs particle and top quark have not been discovered, though the Higgs particle is essential in the Weiberg-Salam theory. Another important issue in this field is the cause of the collapse of the CP symmetry. The second section deals with problems which arise in universalizing the concept of the 'standard theories'. What are required to solve these problems include the discovery of supersymmetric particles, discovery of conflicts in the 'standard theories', and accurate determination of fundamental constants used in the 'standard theories' by various different methods. The third and fourth sections address the Weinberg-Salam theory and quantum chromodynamics (QCD). There are four essential parameters for the 'standard theories', three of which are associated with the W-S theory. The mass of the W and Z bosons measured in proton-antiproton collision experiments is compared with that determined by applying the W-S theory to electron-positron experiments. For QCD, it is essential to determine the lambda constant. (N.K.)

  9. Continuum limit of QED2 on a lattice

    International Nuclear Information System (INIS)

    Weingarten, D.H.; Challifour, J.L.

    1979-01-01

    A path integral is defined for the vacuum expectation values of Euclidean QED 2 on a periodic lattice. Wilson's expression is used for the coupling between fermion and gauge fields. The action for the gauge field by itself is assumed to be a quadratic in place of Wilson's periodic action. The integral over the fermion field is carried out explicitly to obtain a Matthews--Salam formula for vacuum expectation values. For a combination of gauge and fermion fields G on a lattice with spacing proportional to N -+ , Nelement ofZ + , the Matthews--Salam formula for the vacuum expectation /sub N/ has the form /sub n/=∫ dμW/sub N/(G, f), where dμ is an N-independent measure on a random electromagnetic field f and W/sub N/(G,f) is an N-dependent function of f determined by G. For a class of G we prove that as N→infinity, W/sub N/(G,f) has a limit W (G,f) except possibly for a set of f of measure zero. In subsequent articles it will be shown that ∫ dμW (G,f) exists and lim/sub N/→infinity /sub N/ =∫ dμW

The United Nations Commission on International TradeLaw adopted, thus, a Model Law on International Commercial Conciliation in 2002. The EuropeanUnion has also been active in the area of ADR presenting in May 2008 a Directive on CertainAspects of Mediation in Civil and Commercial Matters that represents its most important initiativesin this field. There are also various international conventions that deal with dispute resolution suchas the International Convention on the Settlement of Investment Disputes.

    Science.gov (United States)

    Simpson, Ludi; Marquis, Naomi; Jivraj, Stephen

    2010-01-01

    The School Census is the only regularly updated dataset covering almost all of the population of a specific age, which records changes of address along with ethnicity and some family economic circumstances. It can be used to measure internal and international family migration as shown in this report. The School Census is suited to identify and quantify new local migration streams between censuses, successfully identifying the local distribution of Eastern European immigration in the decade since 2000. The measures do not provide a complete measure of migration, either internally or internationally. The exclusion of those outside the state school system means that internal migration is under-estimated, and international migration is approximately measured. The advantages of the School Census are its frequent updates, its fine geographical information, and its indicators of ethnicity and low family income, which powerfully complement other sources.

    With the increased international competition facing hotel chains, it is essential that the next destination they enter is the most attractive option possible. The host destinations too have a keen interest in strategically positioning themselves in order to attract international hotels since...... their presence has several positive effects. Using, for the first time, actual on-location data we investigate the factors that matter most for international hotels when selecting host destinations. Specifically, we identify 23 factors that make a destination an attractive (or unattractive) location...... for international hotels. We then rank these. The results show that welcomeness, infrastructure, and crime rate are the three most important factors that influence the location of international hotels in host destinations....

  18. What skills should new internal medicine interns have in july? A national survey of internal medicine residency program directors.

    Science.gov (United States)

    Angus, Steven; Vu, T Robert; Halvorsen, Andrew J; Aiyer, Meenakshy; McKown, Kevin; Chmielewski, Amy F; McDonald, Furman S

    2014-03-01

    The transition from medical student to intern may cause stress and burnout in new interns and the delivery of suboptimal patient care. Despite a formal set of subinternship curriculum guidelines, program directors have expressed concern regarding the skill set of new interns and the lack of standardization in that skill set among interns from different medical schools. To address these issues, the Accreditation Council for Graduate Medical Education's Next Accreditation System focuses on the development of a competency-based education continuum spanning undergraduate, graduate, and continuing medical education. In 2010, the Clerkship Directors in Internal Medicine subinternship task force, in collaboration with the Association of Program Directors in Internal Medicine survey committee, surveyed internal medicine residency program directors to determine which competencies or skills they expected from new medical school graduates. The authors summarized the results using categories of interest. In both an item rank list and free-text responses, program directors were nearly uniform in ranking the skills they deemed most important for new interns-organization and time management and prioritization skills; effective communication skills; basic clinical skills; and knowing when to ask for assistance. Stakeholders should use the results of this survey as they develop a milestone-based curriculum for the fourth year of medical school and for the internal medicine subinternship. By doing so, they should develop a standardized set of skills that meet program directors' expectations, reduce the stress of transitions across the educational continuum, and improve the quality of patient care.

    2004-01-01

    After a brief review of quark-lepton relations in grand unified theories (GUT), we show that the Pati-Salam relation with only one type of Higgs field configuration with ''four zero symmetric texture'' can reproduce two large neutrino mixings as well as observed mass differences. This is quite in contrast to the case of SU(5) where bi-large mixings essentially come from the charged lepton sector with non-symmetric charged lepton mass matrix. (author)

    The phenomenology of the standard Weinberg-Salam Higgs boson is reviewed with particular emphasis on production mechanisms in high energy e + e - and hadron-hadron collisions. The production processes relevant for the ISABELLE and TEVATRON energies are discussed and their backgrounds estimated. It is argued that the toponium production and radiative decay provides the most hopeful reaction to detect a Higgs in both the e + e - and the hadron-hadron machines. (orig.)

    We have gauge formulated the spin one-half particle equation in the Duffin-Kemmer formalism of Barut et al. The theory distinguishes between the left and the right chiral states and has a built in chirality. As an example the theory has been applied to the Weinberg Salam model reproducing all its essential features. In view of the built in chirality a lattice gauge version of such a theory is expected to be useful. (author)

    Basing on the simple quark-parton model of strong interaction and on the Weinberg-Salam theory compact formulae are derived for the radiative correction to the charged current induced deep inelastic scattering of neutrinos on nucleons. The radiative correction is found to be around 20-30%, i.e., the value typical for deep inelastic lN-scattering. The results obtained are rather different from the presently available estimations of the effect under consideration

  10. Reinventing US Internal Migration Studies in the Age of International Migration.

    Science.gov (United States)

    Ellis, Mark

    2012-03-01

    I argue that researchers have sidelined attention to issues raised by US internal migration as they shifted focus to the questions posed by the post-1960s rise in US immigration. In this paper, I offer some reasons about why immigration has garnered more attention and why there needs to be greater consideration of US internal migration and its significant and myriad social, economic, political, and cultural impacts. I offer three ideas for motivating more research into US internal geographic mobility that would foreground its empirical and conceptual connections to international migration. First, there should be more work on linked migration systems investigating the connections between internal and international flows. Second, the questions asked about immigrant social, cultural, and economic impacts and adaptations in host societies should also be asked about internal migrants. Third, and more generally, migration researchers should jettison the assumption that the national scale is the pre-eminent delimiter of migration types and processes. Some groups can move easily across borders; others are constrained in their moves within countries. These subnational scales and constraints will become more visible if migration research decentres the national from its theory and empirics.

    1997-01-01

    The 1973 energy crisis demonstrated that the international petroleum industry is not totally free. Very often it has been the object of an organization, even during the domination of international oil companies which have established a petroleum international system with a system of concession rights. This system is based on an oligopolistic structure which had the characteristics of a monopoly. This vertically integrated structure of the world petroleum industry during the 1920-1950 era was more or less locked up by the system of concessions. The incompatibility of this system of excessively long concession contracts with the economical development needs of oil exporting countries has led to their abolishment. They have been replaced by new agreements. As soon as the creation of stable and permanent international oil organizations (OPEC, OAPEC, IEA), an institutional right has been established which has generated international rights and principles governing the contractual relations between oil exporting and oil importing countries. This international petroleum right is both original and specific, it is evolutive, contractual and normative. (J.S.)

    The International Space Station is a valuable platform for research in space, but the benefits are limited if research is only conducted by individual countries. Through the efforts of the ISS Program Science Forum, international science working groups, and interagency cooperation, international collaboration on the ISS has expanded as ISS utilization has matured. Members of science teams benefit from working with counterparts in other countries. Scientists and institutions bring years of experience and specialized expertise to collaborative investigations, leading to new perspectives and approaches to scientific challenges. Combining new ideas and historical results brings synergy and improved peer-reviewed scientific methods and results. World-class research facilities can be expensive and logistically complicated, jeopardizing their full utilization. Experiments that would be prohibitively expensive for a single country can be achieved through contributions of resources from two or more countries, such as crew time, up- and downmass, and experiment hardware. Cooperation also avoids duplication of experiments and hardware among agencies. Biomedical experiments can be completed earlier if astronauts or cosmonauts from multiple agencies participate. Countries responding to natural disasters benefit from ISS imagery assets, even if the country has no space agency of its own. Students around the world participate in ISS educational opportunities, and work with students in other countries, through open curriculum packages and through international competitions. Even experiments conducted by a single country can benefit scientists around the world, through specimen sharing programs and publicly accessible "open data" repositories. For ISS data, these repositories include GeneLab and the Physical Science Informatics System. Scientists can conduct new research using ISS data without having to launch and execute their own experiments. Multilateral collections of research

    International Nuclear Information System (INIS)

    Rodriguez, G.; Wisner, R.S.; Stuart, R.

    2004-01-01

    The role of the fast breeder reactor prototype Monju has expanded to meet the challenges of the 21st century. Today instead of being merely a demonstration of an economical, safe, environmentally responsible source of energy, as originally designed, it has also the capability to be transformed into a unique International Irradiations Test Facility. The potential for Monju's role in the Generation IV nuclear energy systems development, and fast reactor research and development area is clear. Its incomparable fast neutron spectrum density will be a major interest not only for Sodium Fast Reactor but for all the Generation IV concepts. As Monju's potential future role is laid out, plans for future tests can be made. Tests of advanced fuels and materials in support of the Advanced Fuel Cycle Initiative, as well as Minor Actinide Burning can be envisaged. Tests planned on transmutation of minor actinides have the objectives of an industrial demonstration of the reduction of toxic wastes and the stewardship burden of the long-lived wastes. Tests and demonstrations carried out at Monju will provide a bridge from existing Generation III fast reactor systems, now in the later stages of their projected operational lifetimes, to Generation IV nuclear energy systems. The JNC founded the International Cooperation and Technology Development Center and the International Research Fellowship program to facilitate this international effort. The Center exists specifically to formulate and perform projects ensuring the maximum technical benefit from Monju. The staff includes physicists, engineers and nuclear industry leaders from around the world. Research Fellowships center is based on several technical areas: advanced instrumentation, inspection techniques, plant reliability and safety, nucleonics, sodium handling technologies, irradiation and experiment management and coordination and advanced post-irradiation examination capabilities and techniques.

The relevance of this study comes not only from the existence of a vast literature on the topic but especially from the specific features of these agreements. The emphasis of the survey...... is on coalition games, an approach that has become prominent in the fisheries economics literature over the last decade. It is shown that coalition games were first applied to international fisheries agreements in the late 1990s addressing cooperative issues under the framework of characteristic function games...... and stability of international fisheries agreements. A key message that emerges from this literature strand is that self-enforcing cooperative management of internationally shared fish stocks is generally difficult to achieve.

Nuclear Security is prevention of, detection of and response to criminal or intentional unauthorized acts involving or directed at nuclear material, other radioactive material, associated facilities, or associated activities. Nuclear Security includes physical protection, security of radioactive sources, nuclear forensics, nuclear smuggling prevention, border monitoring, and cyber security with regard to nuclear and other radiological materials. This abstract will review recent international trends and discuss the nuclear security regime in the Republic of Korea (ROK). The international Nuclear Security Regime has been strengthened. The upcoming Chicago Summit in 2016 and the entry into force of the Amendment of Convention on Physical Protection of Nuclear Materials (CPPNM) will bring major changes in nuclear security. The Republic of Korea hosted the 2012 Seoul Summit and strengthened domestic regime to meet international standards.

    2009-01-01

    In this study we examine which factors predict internal and international migration from Chitwan, a flat valley located in the South-Central region of Nepal, seeking to measure the effect of theoretically specified variables such as human capital, social capital, physical capital, and neighborhood socioeconomic conditions while controlling for demographic variables. We use data from the Chitwan Valley Family Study (CVFS) to estimate a series of discrete time event history models of first and repeat migration to three competing destinations: other locations within Chitwan, other districts within Nepal, and places outside of Nepal. Results support hypotheses derived from neoclassical economics, the theory of new economics of migration, social capital theory, and cumulative causation theory. Our results underscore the need for a synthetic theoretical model that incorporates factors operating at the individual, household, and community levels. The use of multiple explanatory models yields a clearer picture of the forces driving internal and international migration from rural districts in developing nations such as Nepal.

    We analyse network competition in a market with international calls. National regulatory agencies (NRAs) have incentives to set regulated termination rates above marginal cost to extract rent from international call termination. International network ownership and deregulation are alternatives to combat the incentives of NRAs to distort termination rates. We provide conditions under which each of these policies increase efficiency and aggregate welfare. Our findings provide theoretical suppor...

  13. International safeguards and international nuclear trade

    International Nuclear Information System (INIS)

    Felten, P.

    1991-01-01

    A particular feature of nuclear trade is the need to ensure a good equilibrium between technology transfer and the requirements linked to non proliferation of nuclear weapons. The recent dramatic changes that occurred on the international scene have particularly underlined the difficulty to reach this equilibrium, reminding us the fragility of the existing order and the responsibility of the nuclear community in the field of non-proliferation. Consequently, there is a need for an international thorough review of the actual non proliferation tools developed until now. This review could lead to reconsider some of the dogmas upon which the present safeguard system is based

  14. Three-quark forces and the role of meson exchanges in weak NN interaction

    Grach, I.; Shmatikov, M.

    1989-01-01

    The contribution of weak three-quark forces involving meson exchanges to the longitudinal analyzing power A L in the low-energy pp-scattering is calculated. The nonrelativistic potential model is used for the desorption of strong quark interactions while their weak coupling is described by the Weinberg-Salam lagrangian. The dominant mechanism of parity violation in the NN system (provided the one-pion exchange is forbidden by selection rules) is the contact interaction of quarks. 17 refs.; 3 figs

    We consider classical solutions for the strong gravity theory of Salam and Strathdee in a wider class of metrics with positive, zero and negative curvature. It turns out that such solutions exist and their relevance for quark confinement is explored. Only metrics with positive curvature (spherical symmetry) give a confining potential in a simple picture of the scalar hadron. This supports the idea of describing the hadron as a closed microuniverse of the strong metric. (author)

    The results of calculations of the total capture rates in heavy nuclei, into account the nucleon velocity-dependent terms in the Fujii-Primakoff Hamiltonian and the effective mass of nucleons inside the nucleus, are presented along with the recent experimental data. The results are in general agreement with experiment. However, they indicate a possible deviation from SU(4) symmetry and, in some nuclei, support the Salam-Strathdee idea of the vanishing of the Cabibbo angle at large magnetic fields.

    An extended version of the Glashow-Weinberg-Salam model for the eletroweak interactions is studied in detail. It has an extra global horizontal symmetry, which allows the appearance of neutrino mass terms. The constraints imposed by the standard cosmological model were used to determine the allowed range of variations of the free parameters of this model. As applications, the solar neutrinos problem and the formation of large scale structures in the universe is studied. (Author) [pt

  4. The emerging international constitutional order: the implications of hierarchy in international law for the coherence and legitimacy of international decision-making

    Directory of Open Access Journals (Sweden)

    E de Wet

    2007-11-01

    Full Text Available The article examines the contours and implications of the emerging international constitutional order. The "constitutional" nature of this order relates to the fact that it contains certain fundamental substantive and structural norms that form a supreme legal framework for the exercise of public power. The substantive elements primarily include the value system of the international legal order, meaning norms of positive law with a strong ethical underpinning (notably human rights norms that have acquired a special hierarchical standing vis-à-vis other international norms through state practice. The structural elements refer to the subjects of the international legal order that collectively constitute the international community (polity, as well as the mechanisms for enforcement of the international value system. This vision of an international constitutional model is inspired by the intensification in the shift of public decision-making away from the nation state towards international actors of a regional (for example EU or functional (for example WTO, UN nature, and its eroding impact on the notion of a “total” constitutional order, where the fundamental substantive and structural norms that form the supreme legal framework for the exercise of public power are concentrated in the nation state. It is also inspired by the belief that such a supreme legal framework is only possible in a system where different national, regional and functional legal orders complement each other in order to form an international constitutional order.

    In the near future the experiment will reach a great precision and will be able to test the standard electroweak theory. It is important now to put in order calculations of radiative corrections in this theory and to make correct and exact present theoretical predictions for the measured quantities. The survey of some results of group working in the JINR, Dubna, may serve this aim. We discuss here on-mass-shell renormalization scheme in the unitary gauge; the one-loop amplitudes of both charge and neutral currents-induced fermion scatterings; the large constant effects; the dynamical behaviour of the one-loop neutral-current corrections; the calculation of the W-and Z-boson masses; the difference between the various Weinberg parameters sin 2 Θ W . 44 refs., 10 figs., 1 tab.

  8. The precautionary principle in international environmental law and international jurisprudence

    Directory of Open Access Journals (Sweden)

    Tubić Bojan

    2014-01-01

    Full Text Available This paper analysis international regulation of the precautionary principle as one of environmental principles. This principle envisages that when there are threats of serious and irreparable harm, as a consequence of certain economic activity, the lack of scientific evidence and full certainty cannot be used as a reason for postponing efficient measures for preventing environmental harm. From economic point of view, the application of precautionary principle is problematic, because it creates larger responsibility for those who create possible risks, comparing to the previous period. The precautionary principle can be found in numerous international treaties in this field, which regulate it in a very similar manner. There is no consensus in doctrine whether this principle has reached the level of international customary law, because it was interpreted differently and it was not accepted by large number of countries in their national legislations. It represents a developing concept which is consisted of changing positions on adequate roles of science, economy, politics and law in the field of environmental protection. This principle has been discussed in several cases before International Court of Justice and International Tribunal for the Law of the Sea.

    2014-10-01

    Full Text Available This discussion of a review article by [27], published in the Journal of Palaeogeography (2(1: 56– 65, is aimed at illustrating that interpretations of ten ancient examples in China and one in the central Appalachians (USA as deep-water deposits of internal waves and internal tides are unsustainable. This critical assessment is based on an in-depth evaluation of oceanographic and sedimentologic data on internal waves and internal tides derived from 332 print and online published works during 1838–January 2013, which include empirical data on the physical characteristics of modern internal waves and internal tides from 51 regions of the world’s oceans [108]. In addition, core and outcrop descriptions of deep-water strata from 35 case studies worldwide carried out by the author during 1974–2011, and a selected number of case studies published by other researchers are evaluated for identifying the sedimentological challenges associated with distinguishing types of bottom-current reworked sands in the ancient sedimentary record. The emerging conclusion is that any interpretation of ancient strata as deposits of internal waves and internal tides is premature.

    2017-12-01

    Full Text Available There is not a “Global Code” that encodes the duty of cooperation between tax authorities in the world, concerning the global tax system. This article addresses this issue by proposing a global Code of administrative cooperation in tax matters including both tax relations: between States, and between States, taxpayers and intermediary’s agents. It follows a wide concept of tax governance. The findings of this research have highlighted several practical applications for future practice. article analyses, firstly, the State of the question, starting with the legal sources (international and European sources of hard law and soft law reviewing the differences with the Code as here proposed. It also examines some important Agents who emit relevant normative in international administrative tax cooperation and the role that these agents are developing nowadays (sometimes international organizations but also States like the United States, which Congress enacted the Foreign Account Tax Compliance Act, FATCA. Overlapping and gaps between different regulations are underlined. Finally, the consequences of this “General Code” lack for the functioning of a good international governance, are described. Hence, the need to create an International Cooperation Code on tax matters and international fiscal governance is concluded. That Code could be proposed by any International Organization as the World Bank nature, for instance, or the International Monetary Fund or whichever International or European Organization. This instrument could be documented through a multilateral instrument (soft law, to be signed by the States to become an international legal source (hard law. Filling this Code as Articulated Text (form could be very useful for the International Community towards an International Tax Governance.

  20. Towards a canonical Fermi mass matrix for a pure generation structure

    International Nuclear Information System (INIS)

    Davidson, A.; Wali, K.C.

    1981-01-01

    Vertical constraints on the horizontal generation structure are discussed. The minimal electro/nuclear scheme for which the generation structure must be pure is identified to be the partially unified Pati-Salam SU(4)sub(C)xSU(2)sub(L)xSU(2)sub(R). SO(10) type unification furthermore requires the horizontal group factor to be axial. This in turn crucially affects the Yukawa couplings in such a way that a minimal Higgs system with oply two conventional scalars is capable of uniquely giving rise to the 'canonical' Fritzsch-type mass matrix, for any arbitrary number of fermionic families. The anomaly free equations then provide the desired one-to-one correspondence between the mass matrices in the two charged quark sectors. The derived horizontal quantum numbers suggest that the maximal horizontal group factor be SU(2), with the generations furnishing two neighbor j and j + 1/2 representations. Finally a careful phase analysis shows that the tree-level soft and superweak CP-violation solely reflects the non-Abelian character of the horizontal group, representing an induced internal rotation which is triggered by the phase elimination performed in the vertical sector.

  1. Generalized internal multiple imaging

    KAUST Repository

    Zuberi, M. A. H.

    2014-08-05

    Internal multiples deteriorate the image when the imaging procedure assumes only single scattering, especially if the velocity model does not have sharp contrasts to reproduce such scattering in the Green’s function through forward modeling. If properly imaged, internal multiples (internally scattered energy) can enhance the seismic image. Conventionally, to image internal multiples, accurate, sharp contrasts in the velocity model are required to construct a Green’s function with all the scattered energy. As an alternative, we have developed a generalized internal multiple imaging procedure that images any order internal scattering using the background Green’s function (from the surface to each image point), constructed from a smooth velocity model, usually used for conventional imaging. For the first-order internal multiples, the approach consisted of three steps, in which we first back propagated the recorded surface seismic data using the background Green’s function, then crosscorrelated the back-propagated data with the recorded data, and finally crosscorrelated the result with the original background Green’s function. This procedure images the contribution of the recorded first-order internal multiples, and it is almost free of the single-scattering recorded energy. The cost includes one additional crosscorrelation over the conventional single-scattering imaging application. We generalized this method to image internal multiples of any order separately. The resulting images can be added to the conventional single-scattering image, obtained, e.g., from Kirchhoff or reverse-time migration, to enhance the image. Application to synthetic data with reflectors illuminated by multiple scattering (double scattering) demonstrated the effectiveness of the approach.

    A spontaneously broken gauge theory of leptons (e, μ, ν/sub e'/, ν/sub μ/) is constructed in which the two-body scattering amplitudes are dual. The resultant model leads to suppression of ν/sub μ/ + e → ν/sub μ/ + e and predictions for ν/sub e/ + e → ν/sub e/ + e and e + e → μ + μ - that are distinctly different from those of both the conventional V--A theory and the Weinberg-Salam model.

    We consider a new approach to fermion masses and mixings in which no special 'horizontal' dynamics is invoked to account for the hierarchical pattern of charged fermion masses and for the peculiar features of neutrino masses. The hierarchy follows from the vertical, family-independent structure of the model, in particular from the breaking pattern of the Pati-Salam group. The lightness of the first two fermion families can be related to two family symmetries emerging in this context as accidental symmetries

    The isotopic features of the effective current-current lagrangian of the Lsub(eff) electromagnetic-weak interaction between elementary particles are treated at large momentum transfers using the Weinberg-Salam model. Transition to other models may be made by analogy. It is shown that when the collision energies of elementary particles exceed 90 GeV one may expect the hierarchy in the asymptotic reconstruction of the isotopic symmetry. Such hierarchy could be observed, in particular, in experiments on elastic leptonic collisions at high energies

  16. International certification in developing countries: the role of internal and external institutional pressure.

    Fikru, Mahelet G

    2014-11-01

    This paper examines the different internal and external institutional factors that affect the decision of businesses in developing countries to adopt international certification (IC). Past studies focus on pressure from international laws, the role of multinationals, and businesses mimicking practices of their counterparts in developed countries. This paper finds that, in addition to these external factors, internal factors may have a significant role. Even though environmental regulation is weak in developing countries, governments do not ignore industrial pollution and casualties. They respond by increasing bureaucratic regulations for businesses and this can affect the decision to adopt IC. Furthermore, internal pressure may come from workers' unions that push for a safe and healthy working environment. Published by Elsevier Ltd.

    ITER is being carried out by way of international collaboration between seven partners (the European atomic energy community -EURATOM-, China, India, Japan, Russia, south korea and the United states) which together represent more than half the world population. From a project organisation point of view, it is supported by both financial and in-kind contributions provided by each of the partner; each member makes its contribution through a special legal entity called a 'domestic agency' to an international organisation which was set up by the Agreement on the Establishment of an International Fusion Energy Organization for the joint Implementation of the ITER project signed in Paris on 21. november 2006 and which entered into force on 24. october 2007 after ratification by each of the partners. The international agreement is to remain in effect for a period of 35 years and may be renewed for a period of 10 years without any change to its content. It is supplemented by an agreement of the same date on the privileges and immunities of the organisation and of its staff. The function of the ITER organisation is to construct, commission, operate and permanently shutdown the ITER facility, to encourage their exploitation by laboratories, other institutions and personnel participating in the fusion energy research and development programmes of its members and to promote public understanding and acceptance of fusion energy. The unique institutional structure for this project will be described briefly in the introduction before analysing the law applicable to this international organisation, a French nuclear operator, unique in France today.

    Fell, H.J.

    2007-01-01

    In the contribution under consideration, the author reports on the fact that large international energy agencies, which are advisory active in energy questions active, affect the world-wide policy. In particular, these are the International Atomic Energy Authority in Vienna (Austria) and the International Energy Agency in Paris (France). The International Energy Agency is considered world-wide as the most important institution for all energy questions. Nearly annually, it publishes the World Energy Outlook by summarizing the most important current energy data of the world, prognoses the future power supply and makes future energy prices. The reality of the International Energy Agency looks completely differently: It performs no own sciences, but consists of statisticians, who gather only statistical data without scientific analysis. The author of this contribution summarizes the work of the International Energy Agency in three points: (a) Promotion of the interests of companies in mineral oil, natural gas, coal and atomic energy; (b) Hindering the world-wide conversion of renewable energy; (c) Endangerment of the world economy and prevention of an effective climate protection. The International Energy Agency does not justice to its own goal of a reliable, economical and pollution free power supply

  2. International perspectives on plagiarism and considerations for teaching international trainees.

    2011-01-01

    In the increasingly global community of biomedical science and graduate science education, many US academic researchers work with international trainees whose views on scientific writing and plagiarism can be strikingly different from US norms. Although a growing number of countries and international professional organizations identify plagiarism as research misconduct, many international trainees come from research environments where plagiarism is ill-defined and even commonly practiced. Two research-ethics educators consider current perspectives on plagiarism around the world and contend that US research-training programs should focus on trainees' scientific writing skills and acculturation, not simply on preventing plagiarism.

    Full Text Available To whom do we owe obligations of socio-economic justice? How are such obligations generated? Internationalism denotes a range of approaches to these questions. This paper examines Andrea Sangiovanni's—an internationalist—response to these questions. Sangiovanni argues that we owe egalitarian obligations only to those in the state, and that egalitarian obligations are generated through relationships of ‘reciprocity’. His is a ‘reciprocity-based internationalism’ (RBI. RBI has two components—one normative and another empirical. In this paper, I will assume the normative component, but reject its empirical component. My rejection of the empirical component has normative implications for RBI, which generate egalitarian obligations beyond the state. In other words, my revision of RBI is an argument in favour of international egalitarian obligations not generated through cosmopolitanism, but through internationalism.

    Full Text Available Along with centuries-lasting open military pretensions of world superpowers, modern diplomacy has developed, as beginning a war, as well as coming to peace demanded political activity which resulted, first in signing, and then coming into effect of international documents, on the basis of which, a foundation for the modern international order has been cast. Further on, by the formation of international organizations, codification has been allowed, as well as a progressive development of international law. Additionally, in the sense of preserving international peace and security, first the League of Nations was formed, and following the ending of World War II, the UN. Generally, the functioning of the United Nation's organs, has been regulated by legal rules, however political goals, tendencies, and mechanisms which the member states are using determine greatly the activity above all of the Security Council, but furthermore of the General Assembly, as a plenary organ. Nevertheless, the achieved results of the Commission for International Law in the meaning of creation of international conventions, as well as state adhering to the same, present unassailable achievements in the sense of development of international law. On the other hand, tendencies of motion of international relationships are aimed at establishing a multi-polar system in the international community. Today, the political scene is assuming a new appearance, by which the nearly built international system is already awaiting further progressive development.

    Full Text Available Internal control is indissolubly linked to business and accounting. Throughout history, domestic and international trade has grown exponentially, which has led to an increasing complexity of internal control, to new methods and techniques to control the business. The literature has presented the first models of internal control in the Sumerian period (3600 - 3200 BC, and the emergence and development of internal control in Egypt, Persia, Greek and Roman Empire, in the Middle Ages till modern times. The purpose of this article is to present the models of internal control in Romania, starting from the principles of the classical model of internal control (COSO model. For a better understanding of the implication of internal control in terms of public and private sector, I have structured the article in the following parts: (a the definition of internal control in the literature; (b the presentation of the COSO model; (c internal control and internal audit in public institutions; (d internal control issues in accounting regulations on the individual and consolidated annual financial statements; (e internal / managerial control; (f conclusions.

    2007-12-01

    Full Text Available Since the restoration of democracy, Spain’s successive governments have been noted for their favourable stance toward the issue of Palestine and their support for the creation of a sovereign independent state in the territories that Israel occupied during the Six-Day War. Yasser Arafat’s visit to Spain in the time of the UCD, the holding of the Madrid Conference during the term of government of the PSOE and the designation of Miguel Ángel Moratinos as the EU’s special envoy for the Peace Process during the Partido Popular’s term of government are some of the landmarks that have expressed this exemplary relationship between the Spanish State and the Palestine question. However, the victory of Hamas in the legislative elections of 25 January 2006 radically changed the situation, as it led to Rodríguez Zapatero’s government joining the international boycott of the new Islamist executive; even so, the Spanish government clearly maintained its support for restarting the Peace Process, in the form of its backing for Mahmud Abbas, the President of the Palestine Authority. The armed conflict in Gaza in June 2007 which led to the Islamists retaking the Gaza Strip and the formation of a new government in the West Bank led by the technocrat Salam Fayad served to normalise the situation, given that it encouraged the raising of international sanctions and a return to normality in Spanish-Palestine relations.

    Introduction Internal medicine (IM) interns start continuity clinic with variable ambulatory training. Multiple other specialties have utilized a boot camp style curriculum to improve surgical and procedural skills, but boot camps have not been used to improve interns’ ambulatory knowledge and confidence. The authors implemented and assessed the impact of an intern ambulatory boot camp pilot on primary care knowledge, confidence, and curricular satisfaction. Methods During July 2014, IM interns attended ambulatory boot camp. It included clinically focused case-based didactic sessions on common ambulatory topics as well as orientation to the clinic and electronic medical records. Interns anonymously completed a 15-question pre-test on topics covered in the boot camp as well as an identical post-test after the boot camp. The interns were surveyed regarding their confidence and satisfaction. Results Thirty-eight interns participated in the boot camp. Prior to the boot camp, few interns reported confidence managing common outpatient conditions. The average pre-test knowledge score was 46.3%. The average post-test knowledge score significantly improved to 76.1% (pinterns reported that the boot camp was good preparation for clinics and 97% felt that the boot camp boosted their confidence. Conclusions The ambulatory boot camp pilot improved primary care knowledge, and interns thought it was good preparation for clinic. The ambulatory boot camp was well received and may be an effective way to improve the preparation of interns for primary care clinic. Further assessment of clinical performance and expansion to other programs and specialties should be considered. PMID:26609962

    This history presents a review of International Mycological Association activities, its international congresses, and its relationships with regional mycological associations as well as with international organizations of other scientific disciplines. The IMA was organized in 1971 during the First Mycological Congress (IMC-1) convened at Exeter, U.K. In the period 1971 to 2010, nine international congresses have been held, each with its own organizational structure but under the guidance of one of the successive inter-Congress management groups of IMA officers and executive committee members. The congress list includes Exeter, U.K.; Tampa, U.S.A.; Tokyo, Japan; Regensburg, Germany; Vancouver, Canada; Jerusalem, Israel; Oslo, Norway; Cairns, Australia; and Edinburgh, Scotland. Inter-congress activities of each IMA executive group are summarized. The characteristics of each congress are surveyed as to organization, programming, attendance numbers, finances, and satellite meetings.The IMA has sponsored the establishment of Regional Mycological Associations beginning in 1977 and has lent operational funding. Regional associations currently are functional and hold their own regional congresses in Africa, Asia, Australasia, Europe, and Latin America. The relationships of the IMA with other organizations recognized within the supra-national International Council of Scientific Unions are discussed.

  15. Internal and International Migration Across the Urban Hierarchy in Albania.

    Lerch, Mathias

    2016-01-01

    The interactions between the processes of urbanization and international migration in less developed and transition countries have important repercussions for socioeconomic development, but are not well understood. Based on the retrospective data from the Albanian Living Standards Measurement Survey 2008, we first assess the geography of migration in terms of the rural-urban continuum, the urban hierarchy and the outside world since 1990. We then investigate the spatio-temporal diffusion of rural-to-urban and international movements using survival models. Results reveal an immediate onset of large-scale rural exodus, despite the post-communist crisis. Internal migrants mainly moved to the capital, bypassing secondary cities, and were predominantly female. Initially, international migrants were primarily men who tended to originate from the main urban agglomerations. The diffusion of opportunities to emigrate down the urban hierarchy and across the sexes then redirected the rural exodus abroad, despite domestic economic development. This evolution in population mobility is related to the gendered patterns and interlinkages of the two flows, as well as to rising inequalities within the urban hierarchy.

    Full Text Available This article reports on the first Virtual International Practice Development Conference, held in May 2015 to celebrate International Nurses Day. The article describes key aspects of its planning, offers a flavour of the event itself and sets out an evaluation, including learning points and recommendations to assist with planning similar events in the future. Central to our learning are: The need for practice developers to grasp skills in technology associated with virtual space The need to embrace virtual space itself as another means by which creative and communicative spaces can be established for active learning and practice development activities The potential advantages that international virtual engagement has over face-to-face national or international engagement The delivery of this virtual event made a significant international contribution to global practice development activity within the International Practice Development Collaborative and to enabling practice developers to connect and celebrate on a more global basis. Implications for practice: Virtual space technology skills can assist with sharing and translating practice development research, innovations and critical commentary Virtual space can provide an adjunct to creative and communicative learning spaces Global networking opportunities can be developed and enhanced through the use of virtual space technology Practice developers need to role model the use of virtual technologies

    The primary objective of the present study was to learn the factors that influence the documentation practices of ED interns. A second objective was to identify the expectations of emergency physicians (EPs) towards the medical record documentation of ED interns. A qualitative design was adopted using semi-structured interviews in convenience samples drawn from both groups. Eighteen interviews were conducted with intern volunteers and 10 with EP volunteers. One (5%) intern and two (20%) EPs had received medical documentation training. Factors that encouraged interns' documentation included: patient acuity (the more critical the condition, the more comprehensive the documentation) and the support of senior colleagues. Inhibiting factors included uncertainty about how much to write, and the shift being worked (interns indicated they wrote less at night). Factors of consequence to senior personnel included the apparent reluctance of interns to document management plans. They noted that interns frequently confine their notes to assessment, investigations and treatments, whereas EPs preferred records that demonstrated intern thought processes and included such matters as future actions to follow immediate treatment. A positive theme that emerged included the high level of support interns received from their senior colleagues. Another theme, the influence of patient acuity, held both positive and negative implications for intern writing practices. The lack of formal training is an impediment to the production of useful medical records by ED interns. One solution proposed by both interns and senior personnel was the introduction of the subject into intern education programmes. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    -Danish students receive the basic international and intercultural skills and knowledge they need in current society. The English-language masters’ seminars I teach at the Department of Political Science are international in terms of students and teacher, but they are also Active Learning seminars......-Danish students (and sometimes teachers) rarely speak to each other or learn each other’s names. In the international AL spaces I create, students must work together on joint tasks which require interaction to address tasks and integration in order to benefit from the multinational activity groups. Planning AL...... that complete the seminar soon become vocal advocates of international AL. Ultimately, enriching student learning through immersing Danish and international students in an international AL space is, for me, the best way of ensuring an internationalised learning outcome, rather than just international mobility....

    Full Text Available Financing (funding is essentially the purchase of funds necessary for a business. This can be done from internal sources (company’s own funds or external (borrowed funds. The high value of goods traded in international trade makes revenues generated from internal resources not sufficient to settle the value of the goods. Thus, it is frequent to resort to borrowed funds. In International Business Transactions, external financing is done both by classical techniques of credit (credit supplier and buyer credit and modern techniques of financing (factoring, forfeiting, leasing all trade tailored.

  3. The Development of International Law Through the Unauthorised Conduct of International Institutions

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available The law, including international law, is subject to continuous change. It can be adapted to changing circumstances through formal amendments of or additions to existing norms and practices. It can also be changed through the conduct of international institutions that is not within their legally defined competencies, provided - it will be argued - that the unauthorised conduct (a is not expressly forbidden by existing rules of international law, and (b is accepted or condoned by a cross-section of the international community of states. The creation by the Security Council of the United Nations of ad hoc international criminal tribunals, for example, cannot even with a stretch of the imagination be justified on the basis of the powers of the Council stipulated in the UN Charter. However, their creation was applauded by the nations of the world as a feasible and practical way of responding to the atrocities of the early 1990's in the former Yugoslavia and Rwanda. The creation of international criminal tribunals by the Security Council has thus come to be accepted as a new rule of international law. The same reasoning is applied to the newly acquired competence of NATO forces to intervene militarily on humanitarian grounds as exemplified by the NATO bombing campaign of 1999 in Serbia, while not one of the NATO countries was being attacked or under threat of an attack, and the competence of States to attack terrorist groups in a foreign country if the government of that country is either unwilling or unable to prevent the ongoing acts of terror violence.

    This bulletin contains information about activities of the Nuclear Regulatory Authority of the Slovak Republic (UJD). In this leaflet the international relations and co-operation of the UJD are presented. International community is aware of the fact that nuclear energy shall be used exclusively for peaceful purposes and on condition of high standard of nuclear safety. Therefore, the long-term aim of UJD in the area of international relations is to maintain and develop internationally recognised system of state supervision upon the peaceful use of nuclear energy and to reach internationally accepted level of nuclear safety in the Slovak Republic. There are many important international treaties (Treaty on the Non-proliferation of Nuclear Weapons Convention on Nuclear Safety, etc.) to which slovakia is a party. In order to meet the obligations of these treaties UJD has the main aim for contribute to the process of international disarmament, and to a mutually advantageous co-operation. By means of the most important international organisations (e.g. International Atomic Energy Agency) the Slovak Republic actively participates in the international co-operation. Under the leadership of UJD, Slovak institutions participate in many projects and activities which have the aim to improve the safety of nuclear international obligations. In addition, UJD actively participates in the integration process of the Slovak Republic into European and Trans-Atlantic structures. Since 1993 the co-operation with the European Commission and the Nuclear Energy Agency of Organisation for Economic Co-operation and development (OECD/NEA) has been successfully implemented. Besides multilateral co-operation UJD attaches extraordinary importance to bilateral co-operation, in particular with neighbouring countries. Regular meetings of senior Slovak experts with foreign experts are organised, with the aim to exchange the newest experiences and information on peaceful use of nuclear energy. Also in

    An international expert consensus committee recently recommended a brief battery of tests for cognitive evaluation in multiple sclerosis. The Brief International Cognitive Assessment for MS (BICAMS) battery includes tests of mental processing speed and memory. Recognizing that resources for validation will vary internationally, the committee identified validation priorities, to facilitate international acceptance of BICAMS. Practical matters pertaining to implementation across different languages and countries were discussed. Five steps to achieve optimal psychometric validation were proposed. In Step 1, test stimuli should be standardized for the target culture or language under consideration. In Step 2, examiner instructions must be standardized and translated, including all information from manuals necessary for administration and interpretation. In Step 3, samples of at least 65 healthy persons should be studied for normalization, matched to patients on demographics such as age, gender and education. The objective of Step 4 is test-retest reliability, which can be investigated in a small sample of MS and/or healthy volunteers over 1-3 weeks. Finally, in Step 5, criterion validity should be established by comparing MS and healthy controls. At this time, preliminary studies are underway in a number of countries as we move forward with this international assessment tool for cognition in MS.

  11. [What is Internal Medicine?].

    Science.gov (United States)

    Reyes, Humberto

    2006-10-01

    Internal Medicine can be defined as a medical specialty devoted to the comprehensive care of adult patients, focused in the diagnosis and non surgical treatment of diseases affecting internal organs and systems (excluding gyneco-obstetrical problems) and the prevention of those diseases. This position paper reviews the history of Internal Medicine, the birth of its subspecialties and the difficulties faced by young physicians when they decide whether to practice as internist or in a subspecialty. In Chile as in most occidental countries formal training in a subspecialty of internal medicine requires previous certification in internal medicine but the proportion of young physicians who remain in practice as general internists appears to be considerably lower than those who choose a subspecialty. The main reasons for this unbalance can be related to financial advantages (by the practice of specialized technologies) and the patients' tendency to request direct assistance by a professional thought to be better qualified to take care of their specific problems. Training programs in internal medicine should consider a greater emphasis in comprehensive outpatient care instead of the traditional emphasis for training in hospital wards.

  12. Cancer from internal emitters

    Boecker, B.B.; Griffith, W.C. Jr.

    1995-01-01

    Irradiation from internal emitters, or internally deposited radionuclides, is an important component of radiation exposures encountered in the workplace, home, or general environment. Long-term studies of human populations exposed to various internal emitters by different routes of exposure are producing critical information for the protection of workers and members of the general public. The purpose of this report is to examine recent developments and discuss their potential importance for understanding lifetime cancer risks from internal emitters. The major populations of persons being studied for lifetime health effects from internally deposited radionuclides are well known: Lung cancer in underground miners who inhaled Rn progeny, liver cancer from persons injected with the Th-containing radiographic contrast medium Thorotrast, bone cancer from occupational or medical intakes of 226 Ra or medical injections of 224 Ra, and thyroid cancer from exposures to iodine radionuclides in the environment or for medical purposes

  13. Immunity of international organizations

    CERN Document Server

    Schrijver, Nico

    2015-01-01

    Immunity rules are part and parcel of the law of international organizations. It has long been accepted that international organizations and their staff need to enjoy immunity from the jurisdiction of national courts. However, it is the application of these rules in practice that increasingly causes controversy. Claims against international organizations are brought before national courts by those who allegedly suffer from their activities. These can be both natural and legal persons such as companies. National courts, in particular lower courts, have often been less willing to recognize the immunity of the organization concerned than the organization s founding fathers. Likewise, public opinion and legal writings frequently criticize international organizations for invoking their immunity and for the lack of adequate means of redress for claimants. It is against this background that an international conference was organized at Leiden University in June 2013. A number of highly qualified academics and practit...

    1988-01-01

    Boiling water reactor (BWR) internal components play an important role in power plant life extension. Many important internals were not designed for easy removal and changes in material properties and local environmental effects due to high radiation makes stress corrosion cracking more likely and more difficult to correct. Over the past several years, operating experience has shown that inspection, monitoring and refurbishment can be accomplished for internal structures with existing technology. In addition, mitigation techniques which address the causes of degradation are available to assure that life extension targets can be met. This paper describes the many considerations and aspects when evaluating life extension for reactor vessel internals

    Internal audit can not only allay external and internal concerns about appropriateness of business operations, but also help improve efficiency and the bottom line. To get an internal audit function under way, healthcare organizations need to obtain board buy-in, form an audit committee of the board, determine resources needed, perform a risk assessment, and develop an internal audit plan.

    International Nuclear Information System (INIS)

    Qadir, A.; Sayed, W.A.

    1979-01-01

    It is shown that the strong gravity theory of Salam et al. places severe restrictions on black hole evaporation. Two major implications are that: mini blck holes (down to masses approximately 10 -16 kg) would be stable in the present epoch; and that some suggested mini black hole mechanisms to explain astrophysical phenomena would not work. The first result implies that f-gravity appears to make black holes much safer by removing the possibility of extremely violent black hole explosions suggested by Hawking. (Auth.)

    Nandi, Satyanarayan; Ng, Wing-Chiu.

    1978-06-01

    We analyze the conditions under which several coupling constants in field theory can be related to each other. When the relation is independent of the renormalization point, the relation between any g and g' must satisfy a differential equation as follows from the renormalization group equations. Using this differential equation, we investigate the criteria for the feasibility of a power-series relation for various theories, especially the Weinberg-Salam type (including Higgs bosons) with an arbitrary number of quark and lepton flavors.

  20. Two consistent calculations of the Weinberg angle

    International Nuclear Information System (INIS)

    Fairlie, D.B.

    1979-01-01

    The Weinberg-Salam theory is reformulated as a pure Yang-Mills theory in a six-dimensional space, the Higgs field being interpreted as gauge potentials in the additional dimensions. Viewed in this way, the condition that the Higgs field transforms as a U(1) representation of charge one is equivalent to requiring a value of 30 0 C for the Weinberg angle. A second consistent determination comes from the idea borrowed from monopole theory that the electromagnetic field is in the direction of the Higgs field. (Author)

    The ratio of neutral-current to charged-current cross sections is determined from a sample of events obtained in an exposure of the Fermilab 15-ft hydrogen bubble chamber to a high-energy, horn-focused neutrino beam. For evens with three or more prongs and with visible hadron momentum above 10 GeV/c, the ratio is 0.40 +- 0.14. A Monte Carlo calculation assuming the Weinberg-Salam model is used to correct for excluded events, yielding R/sub NC/CC/ = 0.48 +- 0.17

  9. Internal pump monitoring device

    International Nuclear Information System (INIS)

    Kurosaki, Toshikazu.

    1996-01-01

    In the present invention, a thermometer is disposed at the upper end of an internal pump casing of a coolant recycling system in a BWR type reactor to detect leakage of reactor water thereby ensuring the improvement of reliability of the internal pump. Namely, a thermometer is disposed, which can detect temperature elevation occurred when water in the internal pump leaked from a reactor pressure vessel passes through the gap between a stretch tube and an upper end of the pump casing. Signals from the thermometer are transmitted to a signal processing device by an instrumentation cable. The signal processing device generates an alarm when the temperature signal exceeds a predetermined value and announces that leakage of reactor water occurs in the internal pump. Since the present invention can detect the leakage of the reactor water in the pump casing in an early stage, it can contribute to the improvement of the safety and reliability of the internal pump.

    1993-01-01

    Matters of global concern-deforestation, global warming, biodiversity loss, sustainable development, fuelwood crises, watershed destruction, and large-scale flooding-frequently involve forests and natural resources. In the future, university students will enter a global setting that more than ever depends on a strong knowledge of international issues. USA land-grant universities are attempting to prepare students for this challenge by improving their international programs including forestry. To improve university programs, several factors will need to be addressed and are discussed, with examples, in this article: commitment of the faculty; program specialization; geographic specialization; reward systems for international contributions; international collaboration; recycled dollars within the university; active teaching programs; research; extention and outreach; language training; international faculty; travel grants; twinning relationships with sister institutions; selective in pursuit of international development assistance; and study centers. 6 refs

  12. Globalisation of international health.

    Science.gov (United States)

    Walt, G

    1998-02-07

    40 years ago, activities in international health were the domain of WHO, governments (based on bilateral agreements), and non-governmental organisations. This has changed. Today, new players (such as the World Bank and, increasingly, the World Trade Organisation) have an influence on international health. As globalisation of trade and markets takes hold, new coalitions and alliances are forming to examine and deal with the direct and indirect consequences on health. This paper examines the changing context of cooperation in international health, and voices concerns about rising potential inequalities in health, both within and between countries. The question of how such changes will affect the actions of organisations working in international health is also addressed.

  13. International safeguards

    International Nuclear Information System (INIS)

    Sanders, B.; Ha Vinh Phuong

    1976-01-01

    Since the start of the post-war era, international safeguards were considered essential to ensure that nuclear materials should not be diverted to unauthorised uses. In parallel, it was proposed to set up an international atomic energy agency within the United Nations through which international cooperation in nuclear matters would be channelled and controlled. Created in 1957, the IAEA was authorized to administer safeguards in connection with any assistance it provided as well as at the request of Member State and of any party to bilateral or multilateral arrangements in its ambit. Today, there are two international treaties requiring that its parties should accept Agency safeguards unilaterally, the Latin America Tlatelolco Treaty of 1967, and the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), operative since 1970, which requires in particular that non-nuclear weapon states should accept Agency safeguards on its peaceful nuclear activities. Thus while NPT covers peaceful nuclear activities indiscriminately in a country, the Agency's original safeguards system is applied according to specific agreements and to given facilities. A basic conflict has now emerged between commercial interests and the increasing wish that transfer of nuclear equipment and know-how should not result in proliferation of military nuclear capacity; however, serious efforts are currently in progress to ensure universal application of IAEA safeguards and to develop them in step with the uses of nuclear energy.

    The US health care system uses diagnostic codes for billing and reimbursement as well as quality assessment and measuring clinical outcomes. The US transitioned to the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) on October, 2015. Little is known about the impact of ICD-10-CM on internal medicine and medicine subspecialists. We used a state-wide data set from Illinois Medicaid specified for Internal Medicine providers and subspecialists. A total of 3191 ICD-9-CM codes were used for 51,078 patient encounters, for a total cost of US $26,022,022 for all internal medicine. We categorized all of the ICD-9-CM codes based on the complexity of mapping to ICD-10-CM as codes with complex mapping could result in billing or administrative errors during the transition. Codes found to have complex mapping and frequently used codes (n = 295) were analyzed for clinical accuracy of mapping to ICD-10-CM. Each subspecialty was analyzed for complexity of codes used and proportion of reimbursement associated with complex codes. Twenty-five percent of internal medicine codes have convoluted mapping to ICD-10-CM, which represent 22% of Illinois Medicaid patients, and 30% of reimbursements. Rheumatology and Endocrinology had the greatest proportion of visits and reimbursement associated with complex codes. We found 14.5% of ICD-9-CM codes used by internists, when mapped to ICD-10-CM, resulted in potential clinical inaccuracies. We identified that 43% of diagnostic codes evaluated and used by internists and that account for 14% of internal medicine reimbursements are associated with codes which could result in administrative errors.

  16. Is international junior success a reliable predictor for international senior success in elite combat sports?

    Science.gov (United States)

    Li, Pingwei; De Bosscher, Veerle; Pion, Johan; Weissensteiner, Juanita R; Vertonghen, Jikkemien

    2018-05-01

    Currently in the literature, there is a dearth of empirical research that confirms whether international junior success is a reliable predictor for future international senior success. Despite the uncertainty of the junior-senior relationship, federations and coaches still tend to use junior success as a predictor for long-term senior success. A range of former investigations utilising a retrospective lens has merely focused on success that athletes attained at junior level competitions. Success that was achieved at senior-level competitions but at a junior age was relatively ignored. This study explored to what extent international senior success can be predicted based on success that athletes achieved in either international junior level competitions (i.e. junior medalists) or senior competitions at a junior age (i.e. early achievers). The sample contains 4011 international male and female athletes from three combat sports (taekwondo, wrestling and boxing), who were born between 1974 and 1990 and participated in both international junior and senior-level competitions between 1990 and 2016. Gender and sport differences were compared. The results revealed that 61.4% of the junior medalists and 90.4% of the early achievers went on to win international medals at a senior age. Among the early achievers, 92.2% of the taekwondo athletes, 68.4% of the wrestling athletes and 37.9% of the boxing athletes could be reliably "predicted" to win international senior medals. The findings demonstrate that specific to the three combat sports examined, international junior success appears to be an important predictor to long-term international senior success.

    Geneva is variously known as the city of peace, the world’s smallest metropolis and a place where great ideas have taken form. It has been the home to philosophers such as Rousseau and Voltaire. It was the centre of the Calvinist reformation and birthplace of the Red Cross.   I hardly need to tell you that it is also a city of great international collaboration in science. Little wonder, then, that over the years, Geneva has developed into the world’s capital of internationalism in the broadest sense of the word.

    2016-09-01

    Full Text Available The status of the internal audit as an important pillar for corporate governance is recognized unanimously; however, this status is gained through a continuous and joined effort of all internal auditors and by a clear and solid vision of the internal audit function’s development, designed by the chief of internal audit. This status recognizes the internal audit’s support for the achievement of company objectives and the improvement of risk management and it also requires continuous quantitative accumulations in the work of internal auditors. From this perspective, the author’s attention focused on the main risks and priorities that the internal audit is facing as they are reflected by international studies and surveys. The conclusions emphasized by the author’s research may be considered important milestones for the improvement of the internal audit function in Romania and for its solid connection to the realities and problems the companies are confronting with.

    In order to execute normalization of high-doses on an international scale and to further promote dosimetry as quality control measures in radiation processing, the International Dose Assurance Service (IDAS) has recently been initiated in the framework of a high-dose standardization programme. IDAS is being provided on the basis of an ''Agreement Concerning the Provision of a Dose Assurance Service by the IAEA to Irradiation Facilities in its Member States''. The aim of the IDAS programme will be to meet stringent requirements for standardization of dosimetry, and to achieve concerted international efforts for quality assurance of radiation processing. Details of the programme and the achievements made to date are discussed. (author). 5 refs

  11. THE CONTEMPORARY INTERNATIONAL LAW. A RELATION BETWEEN HUMAN RIGHTS AND THE INTERNATIONAL HUMANITARIAN LAW

    Full Text Available During an armed conflict, a change in the application of the human right regulations and international humanitarian law can be observed in the practice of contemporary international law. It is possible to observe at UN and International Courts’ levels an interesting trend in the sense of considering the application of both systems simultaneously in cases of international crisis as well as in internal conflicts. This innovation in contemporary international law can be observed initially in the change experimented by the legislation of the Human Rights’ European Court and specially and clearer in the Human Rights’ Inter American Court, which in cases against Honduras, Colombia, Paraguay and other countries, states that the State, being warrantor of the efficient protection of civil population, must apply and honor not only the Human Rights’ American Convention, but also the articles 13th and 14th of the II protocol of the Geneva Conventions of 1949. The convergence of both branches of the Law, and its application may help to achieve a better defense and efficiency of the fundamental rights of the human being.

    2013-01-01

    Issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), the 2013 Internal Control – Integrated Framework(Framework) is expected to help organizations design and implement internal control in light of many changes in business and operating environments since the issuance of the original Framework in 1992. The new Framework retains the core definition of internal control and the five components of internal control, and it continues to emphasize the importance of management judgment in designing, implementing, and conducting a system of internal control, and in assessing its effectiveness. It broadens the application of internal control in addressing operations and reporting objectives, and clarifies the requirements for determining what constitutes effective internal control.

  16. Dyson-Schwinger equations in quantum electrodynamics

    International Nuclear Information System (INIS)

    Slim, H.A.

    1981-01-01

    A quantum field theory is completely determined by the knowledge of its Green functions and this thesis is concerned with the Salam and Delbourgo approximation method for the determination of the Green functions. In chapter 2 a Lorentz covariant, canonical formulation for quantum electrodynamics is described. In chapter 3 the definition of the Green functions in quantum electrodynamics is given with a derivation of the Dyson-Schwinger equations. The Ward-Takahashi identities, which are a consequence of current conservation, are derived and finally renormalization is briefly mentioned and the equations for the renormalized quantities are given. The gauge transformations, changing the gauge-parameter, a, discussed in Chapter 2 for the field operators, also have implications for the Green functions, and these are worked out in Chapter 4 for the electron propagator, which is not gauge-invariant. Before developing the main approximation, a simple, non-relativistic model is studied in Chapter 5. It has the feature of being exactly solvable in a way which closely resembles the approximation method of Chapter 6 for relativistic quantum electrodynamics. There the Dyson-Schwinger equations for the electron and photon propagator are studied. In chapter 7, the Johnson-Baker-Willey program of finite quantum electrodynamics is considered, in connection with the Ansatz of Salam and Delbourgo, and the question of a possible fixed point of the coupling constant is considered. In the last chapter, some remarks are made about how the results of the approximation scheme can be improved. (Auth.)

  17. Prediction of the Cabibbo angle in the vector model for electroweak interactions

    Reifler, F.; Morris, R.

    1985-01-01

    In a recent paper we presented a vector model for the electroweak interactions which is similar to the Weinberg--Salam model but differs in the following features. (1) In the vector model all fermion wave functions are bispinors or equivalently isotropic Yang--Mills triplets (as opposed to a state vector composed of a spinor and bispinors in the Weinberg--Salam model). Particles are distinguished by their Higgs fields. (2) The vector model predicts that sin 2 theta/sub W/ = 1/4 , where theta/sub W/ is the Weinberg angle. (3) The vector model accounts for conservation of lepton number, electric charge, and baryon number. (4) In the vector model an antiparticle is characterized by opposite lepton number, electric charge, and baryon number; yet both particles and antiparticles propagate forward in time with positive energies. In this paper we extend the vector theory to include interactions between fermions and the gauge bosons mediating the electroweak force. We model the bosons as Yang--Mills fields with their own Higgs fields. We further propose a specific configuration of Higgs fields for the u,d,s, and c quarks. With these features, the model accounts for electroweak transitions of quarks and leptons and predicts that cos theta/sub C/ = 0.9744, where theta/sub C/ is the Cabibbo angle. We further show that the vector model accounts for the intrinsic parity of particles and antiparticles, and parity violations and CPT invariance for electroweak interactions

  19. Electroweak symmetry breaking: Higgs/whatever

    International Nuclear Information System (INIS)

    Chanowitz, M.S.

    1990-01-01

    In these two lectures the author discusses electroweak symmetry breaking from a general perspective, stressing properties that are model independent and follow just from the assumption that the electroweak interactions are described by a spontaneously broken gauge theory. This means he assumes the Higgs mechanism though not necessarily the existence of Higgs bosons. The first lecture presents the general framework of a spontaneously broken gauge theory: (1) the Higgs mechanism sui generis, with or without Higgs boson(s) and (2) the implications of symmetry and unitarity for the mass scale and interaction strength of the new physics that the Higgs mechanism requires. In addition he reviews a softer theoretical argument based on the naturalness problem which leads to a prejudice against Higgs bosons unless they are supersymmetric. This is a prejudice, not a theorem, and it could be overturned in the future by a clever new idea. In the second lecture he illustrates the general framework by reviewing some specific models: (1) the Weinberg-Salam model of the Higgs sector; (2) the minimal supersymmetric extension of the Weinberg-Salam model; and (3) technicolor as an example of the Higgs mechanism without Higgs bosons. He concludes the second lecture with a discussion of strong WW scattering that must occur if L SB lives above 1 TeV. In particular he describes some of the experimental signals and backgrounds at the SSC. 57 refs., 12 figs

  20. Gauge theory vortices and their role in cosmology

    Yajnik, U.A.

    1986-01-01

    The Nielsen-Olesen model of strings is generalized to theories with spontaneously broken nonabelian gauge groups. Two new phenomena not possible in the abelian case are pointed out. One is that some of the symmetry generators of the original group may not have a global meaning. This can also happen for the generators of the unbroken subgroup. Another phenomenon is that the entire group of symmetries may not get restored in the core of the vortex. The vortices occurring in a realistic SO(10) Grand Unified Theory (GUT) are discussed in detail. The above mentioned phenomena are exemplified. The Weinberg-Salam symmetry generators are shown to be globally undefinable in some of the vortex sectors. The ansatz for a sector in which a scalar field is nonvanishing in the core of the Vortex is constructed. The subgroup of symmetries remaining unbroken in the core is determined. Fermionic zero-modes are found to occur in some of the vortex sectors of the SO(10) GUT model. The induced fermionic charge is computed using the accepted interpretation, and it is found to change from half integral during the Weinberg-Salam phase transition. It is argued that in this realistic example, an integral spectrum for the fermion number is intuitively more appealing. In the last chapter it is shown that strings could have played the important role of inducing a phase transition in the early universe. Their behavior is analogous to that of seeds in a supercooled medium
