The Standard ISO 15489-1 in German and Spanish: an Interlinguistic Comparison

The aim of this paper is to deepen in the terminology of Records Management established by ISO standards, through a concrete example such as an interlinguistic comparison between UNE ISO 15489-1 and DIN ISO 15489-1, that is, between the Spanish and German versions of the ISO 15489-1. For that, the text is divided into two major and complementary parts, which are similar to both analytical perspectives adopted: the semantic one and the pragmatic one. The first one compares the words per se, taking into account the significant or word form as well as the significance or meaning. In the second part, examples of use from both languages are discussed, concerning the three terms considered essential in the text (Record, Records Management System and Records Management). The main conclusion lies in understanding how important the language is as a discrete tool of work for all information scientists, specially concerning to the standards, where the translators must show their best linguistic strategies to go unnoticed.

High performance cobalt-free Cu1.4Mn1.6O4 spinel oxide as an intermediate temperature solid oxide fuel cell cathode

In this work Cu_1.4Mn_1.6O₄ (CMO) spinel oxide is prepared and evaluated as a novel cobalt-free cathode for intermediate temperature solid oxide fuel cells (IT-SOFCs). Single phase CMO powder with cubic structure is identified using XRD. XPS results confirm that mixed Cu⁺/Cu²⁺ and Mn³⁺/Mn⁴⁺ couples exist in the CMO sample, and a maximum conductivity of 78 S cm⁻¹ is achieved at 800 °C. Meanwhile, CMO oxide shows good thermal and chemical compatibility with a 10 mol% Sc₂O₃ stabilized ZrO₂ (ScSZ) electrolyte material. Impedance spectroscopy measurements reveals that CMO exhibits a low polarization resistance of 0.143 Ω cm² at 800 °C. Furthermore, a Ni-ScSZ/ScSZ/CMO single cell demonstrates a maximum power density of 1076 mW cm⁻² at 800 °C under H₂ (3% H₂O) as the fuel and ambient air as the oxidant. These results indicate that Cu_1.4Mn_1.6O₄ is a superior and promising cathode material for IT-SOFCs.

Reactions of atomic and molecular ions with acetone, 1,1,1- trifluoroacetone, and hexafluoroacetone: An investigation of the effects of molecular structure on the dynamics and kinetics of ion-molecule reactions

A selected ion flow tube study of the reactions of a series of gas-phase atomic cations (S⁺, Xe⁺, O⁺, Kr⁺, N⁺, Ar⁺ and Ne⁺) and molecular ions (SF _n⁺ (n = 1-5), CF_n⁺ (n = 1-3), CF₂Cl⁺, H₃O⁺, NO⁺, N ₂O⁺, CO₂⁺, CO⁺, and N₂⁺) spanning a large range of recombination energies (6.3-21.6 eV), with acetone, 1,1,1-trifluoroacetone, and hexafluoroacetone has been undertaken with the objective of exploring the nature of the reaction ion chemistry as the methyl groups in acetone are substituted for CF₃. The reaction rate coefficients and product ion branching ratios for all 66 reactions, measured at 298 K, are reported. The experimental reaction rate coefficients are compared to theoretically calculated collisional values. Several distinct reaction processes were observed among the large number of reactions studied, including charge transfer (non-dissociative and dissociative), abstraction, ion-molecule associations and, in the case of the reactions involving the reagent ion H₃O⁺, proton transfer.

Qualitätssicherung an Hochschulen. Anforderung an die Qualitätssicherung und ihre Wirkungen. Beiträge zur 1. AQ Austria Jahrestagung 2013

Im Mittelpunkt dieser Tagungspublikation stehen zwei Kernfragen: Erstens: Welche Interessengruppen stellen welche Anforderungen an die Qualitätssicherung? Diese Frage führt zur Diskussion über den Zweck, den unterschiedliche Interessengruppen mit der Qualitätssicherung verfolgen. Die zweite wichtige Kernfrage betrifft die Wirkungen von Qualitätssicherung. Bewirken sie tatsächlich ein Mehr an Qualität oder dienen sie lediglich der Erfüllung von Berichtspflichten? Und damit eng zusammenhängend: Was sind die intendierten, was die nicht intendierten Effekte von Qualitätssicherung? Die Sicht verschiedener politischer Entscheidungsträgerinnen und -träger, die Sicht der Studierenden und die Sicht der Qualitätssicherungsagentur über die Anforderungen und Wirkungen von Qualitätssicherung werden dargestellt. Ebenso beleuchten Beiträge von Repräsentantinnen und Repräsentanten der Hochschulsektoren die beiden Kernfragen. Die Beiträge zeigen, wo gemeinsame und wo unterschiedliche Interessen bestehen.

Calculable lepton masses, seesaw relations, and four neutrino mixings in a 3-3-1 model with an extra U(1) symmetry

We propose a scheme in which the masses of the heavier leptons obey seesaw type relations. The light lepton masses, except the electron and the electron neutrino ones, are generated by one loop level radiative corrections. We work in a version of the 3-3-1 electroweak model that predicts singlets (charged and neutral) of heavy leptons beyond the known ones. An extra U(1)(Omega) symmetry is introduced in order to avoid the light leptons getting masses at the tree level. The electron mass induces an explicit symmetry breaking at U(1)(Omega). We discuss also the mixing matrix among four neutrinos. The new energy scale required is not higher than a few TeV.
