    This article is primarily a case study of the Nuremberg Trials Project at the Harvard Law School Library in Cambridge, Massachusetts. It begins with an historical note about the war crimes trials and their documentary record, including the fate of the several tons of trial documents that were distributed in 1949. The second part of the article is a description of the Harvard Law School Nuremberg project, including its history, goals, logistical considerations, digitization process and challenges, and resulting impact. The structure and function of the project website is described, followed by a description of a typical user experience, the project\u27s current status, comparison to related projects, and plans for the future. Appendices provide information on the current distribution of Nuremberg trial documents within the United States, a bibliography on this topic, and a list of U.S. repositories holding related collections (primarily collections of personal papers of participants)

    Congruence schemes

    A new category of algebro-geometric objects is defined. This construction is a vast generalization of existing F1-theories, as it contains the the theory of monoid schemes on the one hand and classical algebraic theory, e.g. Grothendieck schemes, on the the other. It also gives a handy description of Berkovich subdomains and thus contains Berkovich's approach to abstract skeletons. Further it complements the theory of monoid schemes in view of number theoretic applications as congruence schemes encode number theoretical information as opposed to combinatorial data which are seen by monoid schemes

    The phase diagram of superconducting U ⁣Pt3U\!Pt_{3} in pressure-temperature plane, together with the neutron scattering data is studied within a two component superconducting order parameter scenario. In order to give a qualitative explanation to the experimental data a set of two linearly independent antiferromagnetic moments which emerge appropriately at the temperature \mbox{TN10TcT_{N}\sim 10\cdot T_{c}} and \mbox{TmTcT_{m}\sim T_{c}} and couple to superconductivity is proposed. Several constraints on the fourth order coefficients in the Ginzburg-Landau free energy are obtained.Comment: 17 pages, figures available on request to [email protected]

    The mechanism of radiation action in leukaemogenesis. Isolation of a leukaemogenic filtrable agent from tissues of irradiated and normal C57BL mice.

    IRRADIATION of C57B1 mice induced a high incidence of lymphatic leukaemia, while being refractory to the spontaneous development of the disease. Several investigators have isolated a leukaemogenic agent from these radiation-induced tumours, which produces lymphoid leukaemia when injected into isologous newborn or young adult non-irradiated mice (Lieberman and Kaplan, 1959; Latarjet and Duplan, 1962; Laznicka and Smetanova, 1963; Ilbery and Winn, 1964). It has been assumed that the leukaemogenic agent is present during post-natal life in non-irradiated C57B1 mice, and that ionizing irradiation causes the release of a leukaemogenic agent, in addition to thymus and bone marrow injury, which are essential factors in radiation leukaemogenesis (Kaplan, 1964). Experimental support for this hypothesis was provided by demonstrating the presence of a leukaemogenic agent, for a limited period after completion of the irradiation treatment, in centrifugates prepared from pooled, irradiated, non-]eukaemic thymus and bone marrow (Haran-Ghera, 1966). The aim of the present studies was to isolate a leukaemogenic filtrate fro

    Development of a New Electrodeposition Process for Plating of Zn-Ni-X (X = Cd, P) Alloys: Permeation Characteristics of Zn-Ni-Cd Ternary Alloys

    It is shown that an electrodeposited Zn-Ni-Cd alloy coating produced from sulfate electrolyte inhibits the discharge of hydrogen on carbon steel. The newly developed ternary alloys have approximately ten times higher corrosion resistance when compared to a Zn-Ni alloy. Hydrogen permeation characteristics of Zn-Ni-Cd alloy coatings were studied and compared with those of a bare and a Zn-Ni alloy coated steel. The transfer coefficient, a, exchange current density, io, thickness dependent adsorption-absorption rate constant, k0, recombination rate constant, k3, surface hydrogen coverage, θH, were obtained by applying a mathematical model to experimental results. Alloys obtained from baths containing higher concentration than 3 g/L of CdSO4 in the sulfate plating bath are seen to have superior permeation inhibition properties compared to the Zn-Ni alloy coating and bare steel. The hydrogen permeation current was zero under normal corroding conditions for Zn-Ni-Cd alloy and it increased to 0.3 mA/cm2 at a cathodic overpotential of 250 mV. The hydrogen permeation current density for steel and Zn-Ni alloy under similar conditions were 62.1 and 1.3 mA/cm2, respectively

    Gap anisotropy in the angle-resolved photoemission spectroscopy of Bi_2Sr_2CaCu_2O_{8+\delta}

    Full text link
    The gap anisotropy in Bi2_2Sr2_2CaCu2_2O8+δ_{8+\delta} is revisited in the framework of a d-wave scenario in view of the recent angle-resolved photoemission experiment. Based on a tight-binding fit to the normal state dispersion, a detail analysis on the effects of the inclusion of the next harmonic in the d-wave has been presented. Significant effect has been observed in the superconducting Tc_c. The density of states is linear at the nodes with enhanced weight, caused by a marked increase in the low energy excitaions which affect the thermodynamics considerably. The slope of the ρsT\rho_s - T curve in the low temperature regime increases and the specific heat reflects the enhanced entropy at low temperatures. The leading edge of the ARPES energy distribution curves have been calculated and found to shift towards higher energy. The effect of scattering by non-magnetic impurities in this context is also outlined.Comment: 8 pages, 7 figures (akw.eps and edc.eps in one panel
