2. 1. Effective Spatial Mapping for Coupled Code Analysis of Thermal–Hydraulics/Neutron–Kinetics of Boiling Water Reactors

   Author : Joanna Peltonen; Weimin Ma; Maria Avramova; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boiling Water Reactor; RELAP5; TRACE; PARCS; Coupled TH NK analysis; Spatial Mapping; Turbine Trip; Feedwater Transient; Control Rod Drop; Reactor Stability; Hierarchical Clustering; kokvattenreaktor; reaktoranalys; RELAP5; TRACE; PARCS; TH NK analys; turbin tripp; matarvatten transient; fallande styrstav; reaktor stabilitet; hierarkisk klustringsmetodik; SRA - Energy; SRA - Energi;

   Abstract : Analyses of nuclear reactor safety have increasingly required coupling of full three dimensional neutron kinetics (NK) core models with system transient thermal–hydraulics (TH) codes.  In order to produce results within a reasonable computing time, the coupled codes use two different spatial description of the reactor core.

4. 2. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2

   Author : Elin Andersson; Neurobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; cell replacement; Parkinson?s; dopamine; neuronal specification; development; mesencephalon; TH; neuronal differentiation; proneural genes; transcription factors; bHLH; neurospheres; stem cell; progenitor cell;

   Abstract : Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. READ MORE

5. 3. Development of central catecholaminergic neuronal systems in the lizard Anolis sagrei

   Author : Agneta Rehn; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; double labelling; immunohistochemistry; interplexiform cells; amacrine cells; catecholamines; development; retina; Reptiles; brain; Zoology; Zoologi;

   Abstract : Catecholamines, comprising the neurotransmitters dopamine (DA), noradrenaline (NA) and adrenaline (A) are synthesized by specific enzymes (tyrosine hydroxylase (TH), dopamine ß-hydroxylase (DBH), phenylethanolamine-N-methyltransferase (PNMT)) in the central nervous system. The development and distribution of different catecholaminergic systems have been described in both the brain and retina of the lizard Anolis sagrei. READ MORE

6. 4. Early events in T cell development

   Author : Karin Leandersson; Malmö Cancerimmunologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; pTalpha; gammadelta T cell; alphabeta T cell; development; thymus; thymocyte; serology; transplantation; Immunologi; serologi;

   Abstract : T cells constitute a heterogenous population of lymphocytes. Their unifying property is that they express surface bound antigen-receptors, called T cell receptors (TCRs). The TCR is a heterodimer composed of either TCRalpha and beta chain proteins (alphabeta TCR) or gamma and delta chain proteins (gammadelta TCR). READ MORE

7. 5. Th Dynamics of Star Cluster Formation

   Author : Juan Pablo Farias Osses; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Star Formation; Star Clusters; Stellar Dynamics;

   Abstract : A major question in astrophysics is how star clusters form. These objects are important, since they are the birth sites of most stars, perhaps including our own Sun. READ MORE
