1. 1. Light Control using Organometallic Chromophores

   Författare :Johan Henriksson; Patrick Norman; Olav Vahtras; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organometallic chromophores; two-photon absorption; excited state absorption; excited state dipole moment; four-component formalism; clamping levels; spin-transition; Computational physics; Beräkningsfysik;

   Sammanfattning : The interaction between light and organometallic chromophores has been investigated theoretically in a strive for fast optical filters. The main emphasis is on two-photon absorption and excited state absorption as illustrated in the Jablonski diagram. We stress the need for relativistic calculations and have developed methods to address this issue. LÄS MER

3. 2. Spatio-temporal modeling of morphology and gene-expressions during C.elegans embryogenesis using a new imaging framework

   Författare :Johan Henriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Many aspects of ontogenesis, the process whereby an organism develops from the fertilized egg to a grown adult, are still poorly understood, despite having been studied since Aristotle's time. The advent of modern biology with the sequencing of entire genomes and mapping of all genes offers the promise that one day we will understand how genes function to regulate cell division and differentiation.

4. 3. Molecular Quadratic Response Properties with Inclusion of Relativity

   Författare :Johan Henriksson; Patrick Norman; Juha Vaara; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relativistic quantum chemistry; molecular physics; clamping levels; four-component Hartree-Fock theory; Kohn-Sham density functional theory; response theory; nonlinear optics; second-harmonic generation; two-photon absorption; excited state properties; optical power limiting; Computational physics; Beräkningsfysik;

   Sammanfattning : This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior. LÄS MER

5. 4. Introducing New Materials in the Automotive Industry : Managing the Complexity of Introducing New Materials in Existing Production Systems

   Författare :Fredrik Henriksson; Kerstin Johansen; Jonas Detterfelt; Johan Ölvander; Mats Winroth; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Passenger vehicles are central to Western society, and contribute to a significant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. LÄS MER

7. 5. Gender and physiology in ice hockey : a multidimensional study

   Författare :Kajsa Gilenstam; Karin Henriksson-Larsén; Kim Thorsen; Staffan Karp; Carl Johan Sundberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; physiology; gender; sports medicine; ice hockey; women s sport; athletic performance; social conditions; qualitative method; quantitative method; exercise tests; Sports; Idrott; Gender studies; Genus; Physiology; fysiologi;

   Sammanfattning : Background That men are prioritised over women has been called the “gender regime in sport”, and has in part been explained by the gender difference in performance. However, gender differences in physical performance between women and men can be debated to depend on how comparisons are made and on the fact that there are many different confounders that may influence the results.
