  1. 21. Theoretical Studies of Drug-Metabolizing Cytochrome P450 Enzymes

    Författare :Junhao Li; Yaoquan Tu; Ulf Ryde; KTH; []
    Nyckelord :Cytochrome P450 enzymes; molecular dynamics; quantum chemistry; structural flexibililty; ONIOM; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : The family of cytochrome P450 enzymes (P450s) belongs to one of the most important enzyme families in the human body. P450s are involved in the synthesis of endogenous compounds and metabolism of exogenous substances. LÄS MER

  3. 22. Phenomenology in multi-scalar extensions of the Standard Model

    Författare :Astrid Ordell; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BSM; 2HDMs; BSM; 2HDMs; Fysicumarkivet A:2020:Ordell;

    Sammanfattning : This thesis is composed of four papers, which all treat various extensions to the Standard Model (SM). The first two papers concern a particular supersymmetric, grand-unified theory (GUT), while in the latter two, we classify anomaly-free implementations of two-Higgs doublet models (2HDM) with a gauged abelian symmetry.

  4. 23. The adoption and implementation of International Financial Reporting Standards (IFRS) in Rwanda

    Författare :Jean Bosco Shema; Gunnar Rimmel; Jill F. Atkins; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Accounting has played a significant role in globalization through instruments like the International Accounting Standard Board (IASB), the International Federation of Accountants (IFAC) and the International Financial Reporting Standards (IFRS) which have harmonized global business practices. With the spread of globalization, the persistence of local realities has become a global issue. LÄS MER

  5. 24. A Negative Footprint Illusion in Environmental Impact Estimates

    Författare :Mattias Holmgren; Patrik Sörqvist; Ola Eriksson; Maria Ojala; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; The negative footprint illusion; averaging bias; environmental impact estimates; decision-making; climate change; Den negativa fotavtryckillusionen; genomsnittsprocess; miljöpåverkan; beslutsfattande; klimatförändringarna; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

    Sammanfattning : A major part of anthropogenic climate change is due to everyday human behavior, such as transportation, food and energy consumption. As a result, it has been argued that many barriers for mitigating climate change are psychological in nature. LÄS MER

  7. 25. Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules

    Författare :Peter Martinsson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intra- and intermolecular dynamics.; Zn-porphyrin; bacteriochlorophyll a; chlorophyll b; Femtosecond transient absorption spectroscopy; chlorophyll a; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses.
