2. 11. Ferromagnetic resonance in films with growth induced anisotropy

   Author : Sergey Manuilov; Alex Grishin; Boris Kalinikos; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferromagnetic resonance; magnetic anisotropy; single-ion anisotropy model; ferrites; magnetic epitaxial films; magnetostatic waves; pulsed laser deposition; magnetic alloys; domains; domain wall transformations;

   Abstract : This thesis discusses two different magnetic materials: epitaxial yttrium iron garnet (YIG) and heteromorphous CoFeB-SiO2 films. YIG films were grown by pulse laser deposition (PLD) techniques onto gadolinium gallium garnet (GGG) substrates of (111) and (001) crystal orientations. READ MORE

4. 12. On Some Properties and Applications of Patterned Ferromagnetic Thin Films

   Author : Pierre E. Roy; Peter Svedlindh; Per Nordblad; Jeffrey McCord; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; micromagnetics; vortex; spin dynamics; domains; MFM; microwave; patterned; permalloy; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : A microwave reflection method has been used to measure the spin excitations corresponding to the translational mode of magnetic vortices in samples containing either one or two vortices. Experimental findings are complemented by micromagnetic simulations. One-vortex systems are investigated in micron-sized circular and elliptical cylinders. READ MORE

5. 13. Designing Interactive Learning Environments to Support Learners’ Understanding in Complex Domains

   Author : Marcelo Milrad; Växjö universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; interactive learning environments; complex domains; social constructivism; collaborative learning; construction kits; system dynamics simulations; collaborative modelling tools.; Information technology; Informationsteknologi; Cognitive science; Kognitionsvetenskap; Media Technology; Media Technology;

   Abstract : This dissertation focuses on the design of interactive learning environments (ILEs) to support learning in complex domains. Previous research efforts in this field indicate that we lack a well-articulated design framework with sufficient detail to take us from a socially-situated, problem-based, collaborative learning perspective to the design of a particular learning environment for a particular subject domain.

6. 14. Specifying the Heterogeneity in Children with ADHD : Symptom Domains, Neuropsychological Processes, and Comorbidity

   Author : Cecilia Wåhlstedt; Gunilla Bohlin; Björn Lyxell; Uppsala universitet; []
   Keywords : ADHD; Heterogeneity; Hyperactivity Impulsivity; Inattention; Neuropsychological Pathways; Comorbidity; Psychology; Psykologi;

   Abstract : Heterogeneity in children with Attention Deficit Hyperactivity Disorder (ADHD) symptoms is a well-known phenomenon. Empirically, this heterogeneity is evident in at least three different respects: expression of the two ADHD symptom domains (hyperactivity/impulsivity and inattention), neuropsychological impairments, and comorbid behavior problems.

7. 15. Protein recognition domains in heparan sulfate

   Author : Emadoldin Feyzi Talarposhti; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; heparin; structure; growth factors; herpes simplex virus; antithrombin; aging; regulation; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

   Abstract : Heparan sulfate (HS) is a sulfated glycosaminoglycan (GAG) implicated in various physiological and pathological processes such as cell proliferation, viral infection and inhibition of blood coagulation. These effects are due to interactions of HS with proteins. READ MORE
