  1. 1. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies

    Author : Carsten Meyer-Jacob; Richard Bindler; Hendrik Vogel; Jan Karlsson; John F. Boyle; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Fourier transform infrared spectroscopy; visible-near infrared spectroscopy; PLS regression; biogenic silica; climate change; carbon cycling; lake-water quality; geochemistry; paleolimnology; Holocene; Lake El’gygytgyn; Torneträsk;

    Abstract : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. READ MORE

    Abstract : People engage with multiple online services and carry out a range of different digital transactions with these services. Registering an account, sharing content in social networks, or requesting products or services online are a few examples of such digital transactions. READ MORE

  3. 3. X-ray spectroscopy on diatomic and cationic molecules

    Author : Ludvig Kjellsson; Jan-Erik Rubensson; Marcus Agåker; Monica Turcato; Michael Meyer; John Bozek; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; X-ray absorption spectroscopy; resonant inelastic X-ray scattering; cationic molecule; dinitrogen; dioxygen; carbon monoxide; aqueous hydroxyl radical; lifetime-vibrational interference; RIXS; XAS; LVI; N2; O2; CO; H2O; OH;

    Abstract : X-ray spectroscopy have been used to study the electronic structure of diatomic and cationic molecules. X-ray absorption spectra of the molecular cations N2+, O2+, and CO+ have been measured. READ MORE

  4. 4. Deductive Planning and Composite Actions in Temporal Action Logic

    Author : Martin Magnusson; Patrick Doherty; John-Jules Meyer; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Temporal Action Logic; deductive planning; composite actions; interval algebra; constraint logic programming; execution monitoring; Computer science; Datalogi;

    Abstract : Temporal Action Logic is a well established logical formalism for reasoning about action and change that has long been used as a formal specification language. Its first-order characterization and explicit time representation makes it a suitable target for automated theorem proving and the application of temporal constraint solvers. READ MORE

  5. 5. Mirrors of Change : A Study of Industry Associations in Chile and Uruguay

    Author : Andrés Rivarola Puntigliano; Ulf Jonsson; Jaime Behar; John Meyer; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; institutions; World-culture; remix; industry associations; global; legitimacy; region; Chile; Uruguay; Economic history; Ekonomisk historia; Economic History; ekonomisk historia;

    Abstract : Mirrors of Change is a cross-sectional study of micro and macro institutional environments that envisages to analyse shifts in the sources of institutional legitimacy since the 1960s. The main aim is to understand whether homogenising macro institutions are adopted at the micro institutional levels. READ MORE
