  1. 1. Particle Interferometry in e+e- Annihilation

    Författare :Raluca Muresan; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; DELPHI; Elementary particle physics; LEP; e e- annihilation; Interferometry; Correlation; Bose-Einstein; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2000:Muresan;

    Sammanfattning : This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. LÄS MER

  3. 2. Properties of Hadronization in e+e- -Annihilation

    Författare :Jari Häkkinen; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; högenergi; colour interferences; strong interactions; QCD; heavy quark fragmentation; MC programs; Kosmisk strålning; cosmic rays; hadronization; High energy interactions; e e- -annihilation; Fysicumarkivet A:1996:Häkkinen;

    Sammanfattning : Possible effects from colour interferences in strong interactions are discussed and investigated, and possible experimental signals in e+e- --> hadrons and e+e- --> W+W- --> hadrons are suggested. The observability of the signals depend on the relative probabilities of the occurrence of interferences, and can provide a measurement of the probabilities. LÄS MER

  4. 3. Economic Nationalizing in the Ethnic Borderlands of Hungary and Romania : Inclusion, Exclusion and Annihilation in Szatmár/Satu-Mare 1867–1944

    Författare :Anders E. B. Blomqvist; Anu Mai Köll; Leos Müller; Dennis Deletant; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Economic nationalizing; ethnonationalism; nationalism; economic nationalism; ethnicity; borderland; Hungary; Romania; Austria-Hungary; Transylvania; Holocaust; anti-Semitism; political economy; assimilation; ethnic economy; ethnocracy; minorities; History; historia; Östersjö- och Östeuropaforskning;

    Sammanfattning : The history of the ethnic borderlands of Hungary and Romania in the years 1867–1944 were marked by changing national borders, ethnic conflicts and economic problems. Using a local case study of the city and county of Szatmár/Satu-Mare, this thesis investigates the practice and social mechanisms of economic nationalizing. LÄS MER

  5. 4. Kunskapens yttersta kant : Gud och det givna i K.E.Løgstrups Metafysik

    Författare :Esbjörn Särdquist; Mattias Martinsson; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; God; theology; metaphysics; sensation; order of analogy; time; being; annihilation; the given; theory of knowledge; hermeneutics; philosophy of religion; phenomenology; postmodernism; creation; foundationalism; Religion Theology; Religionsvetenskap Teologi; Religious Studies and Theology; Religionsvetenskap;

    Sammanfattning : The dissertation makes an interpretation of The Metaphysics, four books written by the Danish theologian and philosopher K.E. Løgstrup at the end of his life. In a systematic way the dissertation describes a coherent vision of Løgstrups main theories in the books taken together as a whole. LÄS MER

    Sammanfattning : A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. LÄS MER
