  1. 1. Reactions in the System Nitro-cellulose/ Diphenylamine with Special Reference to the Formation of a Stabilizing Product Bonded to Nitro-cellulose

    Författare :Torbjörn Lindblom; Bengt Nygård; Sten-Eric Lindquist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Nitro-cellulose; NC; Propellant; Stabilizer; Diphenylamine; DPA; Stability; Shelf-life; Chemometry; FTIR; HPLC; Microcalorimetry; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The methods HPLC, microcalorimetry and FTIR together with chemometry, provide good analytical tools to follow the degradation of nitro-cellulose.The degradation products formed from diphenylamine (DPA) during storage can be followed with HPLC. FTIR, together with chemometry, also gives the precision needed for safety control of propellants. LÄS MER

  3. 2. Social causality in motion : Visual bias and categorization of social interactions during the observation of chasing in infancy

    Författare :Martyna A. Galazka; Pär Nyström; Gustaf Gredebäck; Moritz Daum; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social causality; motion; animacy perception; chasing goal-directed motion; heat-seeking; EEG; P400; Nc; spatial proximity; non-contact causality; functional specialization; specialized perception; evolution; Psychology; Psykologi;

    Sammanfattning : Since the seminal work of Fritz Heider and Marienne Simmel (1944) the study of animacy perception, or the perception and attribution of life from the motion of simple geometrical shapes has intrigued researchers. The intrigue for psychologists and vision scientists then and today centered on the stark disconnect between the simplicity of the visual input and the universal richness of the resulting percept.

  4. 3. Multiplet bases, recursion relations and full color parton showers

    Författare :Johan Thorén; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Multiplet Bases; SU Nc ; SU N ; Recursion Relations; BCFW; Nc=3 Parton Showers; Parton Showers;

    Sammanfattning : The papers in this thesis all concern the treatment of colors in perturbative QCD, both in the context of hard scattering cross sections and for parton showers. The complexity of the color structure of QCD increases quickly with the number of external partons. LÄS MER

  5. 4. Precision Standard Model Phenomenology for High Energy Processes

    Författare :Timea Vitos; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; precision phenomenology; Standard Model; NLO electroweak; decay coefficients; Drell-Yan process; top quark spin correlations; colour expansion; large-Nc limit; precision phenomenology; Standard Model; NLO electroweak; decay coefficients; Drell-Yan; top quark spin correlations; colour expansion; large-Nc truncation; Fysicumarkivet A:2023:Vitos;

    Sammanfattning : The present status of particle physics is that the Standard Model has been completed with the discovery of theHiggs boson in 2012, but there is a multitude of phenomena in nature which is not accounted for by this model.Researchers are investigating possibilities for detecting new physics at the current particle physics facilities, withthe Large Hadron Collider (LHC) at the frontier.
