Towards Trusted Identities for Swiss Researchers and their Data

In this paper we report on efforts to enhance the Swiss persistent identifier (PID) ecosystem. We will firstly describe the current situation and the need for improvement in order to describe in full detail the steps undertaken to create a Swiss-wide model. A case study was undertaken by using several data sets from the domains of art and design in the context of the ICOPAD project. We will provide a set of recommendations to enable a PID service that could mint Archival Resource Key (ARK) identifiers or a flavour of Research Resource Identifiers (RRIDs) as complement to Digital Object Identifiers (DOIs). We will conclude with some remarks concerning the transferability of this approach to other areas and the requirements for a national hub for PID management in Switzerland

A calorimetric study of egg white proteins

Egg white is of great interest for many culinary and industrial applications. Egg white is used for coating, gluing, thickening and so on in pasta, desserts, etc. There is thus a great interest from the industrial point of view to better know this raw material, used in very large amounts in the dessert production for example, and to obtain egg white fractions with different functional properties. Various egg white fractions prepared by selected procedures were analyzed by differential scanning calorimetry (DSC). The products resulting from a given fractionation procedure can thus be described by the thermal denaturation parameters (temperatures and enthalpies) of the egg white proteins. This work demonstrates the interest of the DSC technique and proves that the fractionation procedures selected here give the expected protein fractions

Implementing a Video Framework based on IIIF: A Customized Approach from Long-Term Preservation Video Formats to Conversion on Demand

This paper addresses the issue of elaborating a structure for digital video assets based on the International Image Interoperability Framework (IIIF) concepts for the use in archival environments. With a view to tailoring a solution to fit the end user's needs, the dissemination copies of video material could be automatically converted on demand from their master files. Such a reduced data structure simplifies access to digital video sources but leads as well to simplified preservation due to reduced data volume and data complexity. Dissemination copies do not require specific dispositions for digital archiving anymore. Memory institutions would greatly benefit from a technology that can be integrated into a Web-based infrastructure. In such a way video content can for example be embedded into flexible Virtual Research Environments which allow scholars to work and cite more accurately video resources using IIIF

Reactivity of Allenes towards Iron Carbonyl Complexes

A series of monosubstituted allenes was reacted with Fe2(CO)9 to give dinuclear iron-carbonyl complexes containing organic ligands derived either from monomeric or dimerized allene. A mechanism of formation is proposed based on isolated intermediates. These intermediates point to an allene dimerization via addition of a reactive allene iron complex to free allene. Unusual chemical shifts were observed for many resonances in the 1H- and 13C-NMR spectra of the new compounds

Study of ^194 Ir via thermal neutron capture and (d,p) reactions

Levels of ^194 Ir were studied using thermal neutron capture reaction. A pair spectrometer was used to measure the high-energy gamma-ray spectrum from thermal-neutron capture in enriched ^193 Ir target over the energy range 4640 - 6100 keV. The low-energy gamma-radiation from the reaction was studied with crystal diffraction spectrometers, and conversion electrons were observed with magnetic spectrometers. The high-sensitivity measurements at the Grenoble reactor, evaluated for transition energies up to 500 keV, are compared with lower-sensitivity measurements at the Wuerenlingen and Salaspils reactors. The comparison helped to obtain reliable isotopic identification for a number of ^194 Ir lines. The multipolarity admixtures for 29 gamma-transitions were determined on the basis of conversion lines from different electron subshells. Prompt and delayed gamma-gamma coincidences were measured using semiconductor and scintillation detectors. The ^193 Ir(d,p) high-resolution spectra, observed with a magnetic spectrometer, are given. All these data contributed to establishing a detailed level scheme of ^194 Ir. Additional data and the interpretation of the results in terms of current models will be presented in a forthcoming paper
