    The QCD Pomeron in Ultraperipheral Heavy Ion Collisions: IV. Photonuclear Production of Vector Mesons

    Get PDF
    The photonuclear production of vector mesons in ultraperipheral heavy ion collisions is investigated within the QCD color dipole picture, with particular emphasis on the saturation model. The integrated cross section and the rapidity distribution for the A + A --> V + A + A (V = rho, omega, phi, J/Psi) process are computed and theoretical estimates for scattering on both light and heavy nuclei are given for energies of RHIC and LHC. A comparison with the recent STAR data on coherent production of rho mesons is also presented. Furthermore, we calculate the photoproduction of vector mesons in proton-proton collisions at RHIC, Tevatron and LHC energies.Comment: 19 pages, 6 figures and 2 tables.

    The QCD Pomeron in Ultraperipheral Heavy Ion Collisions: V. Double Vector Meson Production in the BFKL Approach

    Get PDF
    In this work the double vector meson production in ultraperipheral heavy ion collisions is investigated within the BFKL approach. The integrated cross sections and event rates for the processes AA --> V1 V2 AA (V_i = rho, omega, phi, J/Psi, Upsilon) are computed and theoretical estimates for scattering on both light and heavy nuclei are given for energies of RHIC and LHC.Comment: 10 pages, 1 figure.

    Changes of perspective introduced by Rousseau in educational practice

    Full text link
    This paper is an attempt to discuss Rousseau’s ideas on educational practice through his book, Emile, arguably one of the most noteworthy books on education available today. Rousseau makes an effort to describe an approach to education based on nature, emphasizing harmony and a strong concern for the child. Such concepts are fundamental in Rousseau’s ideas, which would later impact child development theories of Werner, Pestalozzi, Herbert, Piaget and Vygotsky, albeit with different results and related theories.http://www.aijssnet.com/journals/Vol_2_No_1_January_2013/10.pdfPublished versio

    Impact of emerging and frontier economies on global markets

    Full text link
    The emerging markets have been the source of global economic growth for quite some time now, with far-reaching effects to the rest of the world, in particular to advanced economies. It is not news that emerging markets have become the sweethearts of the financial press and a favorite talking point of governments, foreign trade advisors, and corporations worldwide. Although these markets were best known in the past as a commodity paradise, or the place to go for natural resources, cheap labor, or low manufacturing costs, emerging markets today are positioned for growth. This paper argues that rapid population development, growing middle-class, and sustained economic development is making many international investors and corporations look to emerging markets with new lenses, with substantial impact on advanced economies and the world as a whole.https://www.researchgate.net/publication/309676049_Impact_of_Emerging_and_Frontier_Economies_on_Global_MarketsSupporting documentatio

    The great Dr. Samuel Johnson

    Get PDF
    Almost 230 years ago, the world lost Dr. Johnson, as Samuel Johnson was known, a man of all seasons. Johnson was not only a British writer who made lasting contributions to English literature as a poet, essayist, moralist, literary critic, and biographer; he was also an editor and lexicographer extraordinaire. But he has always been remembered, with the help of his biographer James Boswell, for the greatness of spirit, mind, character, conduct, and art. Such is his great magnanimity, his piety, and eloquence, so overwhelmingly obvious and affecting to those who know his writings, that it is with some difficulty that I write about him, as opposed to quoting from him. Although English is not my first language, I have tremendous respect and admiration for Johnson, probably passed on to me by one of my favorite professors in graduate school at Boston University, Dr. Aeschliman.https://www.researchgate.net/publication/292800062_The_great_Dr_Samuel_JohnsonPublished versionPublished versio
