1. 21. Nanostructured Bulk Thermoelectrics : Scalable Fabrication Routes, Processing and Evaluation

   Författare :Mohsen Yakhshi Tafti; Muhammet S. Toprak; Gao Min; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermoelectric; Iron antimonide FeSb2 Skutterudite; Copper Selenide Cu2Se ; Spark Plasma Sintering SPS ; nanomaterial; Teknisk materialvetenskap; Materials Science and Engineering; Energy Technology; Energiteknik;

   Sammanfattning : Current fossil fuel based energy sources have a huge shortcoming when one discusses their efficiency. The conversion efficiency of fossil fuel-based technologies is less than 40% in best cases. LÄS MER

3. 22. Chemogenetics, Induced Neurons and Pluripotent Stem Cells: Towards Advanced Gene and Cell Therapies Targeting Epilepsy

   Författare :Natalia Avaliani; Epilepsicentrum; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemogenetics; iPS; iN; electrophysiology; gene and cell therapy; Epilepsy;

   Sammanfattning : The complexity of the central nervous system and existence of the blood-brain barrier often causes difficulties for traditional pharmacological treatments of neurological diseases. This thesis explores the feasibility and potential for novel gene and cell therapy approaches, which hold better promise for neurological disorders, while particularly targeting epilepsy. LÄS MER

4. 23. THE HYPOXIC HEMATOPOIETIC STEM CELL NICHE Consequences of Hypoxia-induced Transcription on Stem Cell Fate

   Författare :Matilda Rehn; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic Stem Cells; Stem Cell Niche; Hypoxia; Hypoxia-Inducible Factor; Vegfa.;

   Sammanfattning : Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. LÄS MER

5. 24. Neuronal and glial differentiation of expanded neural stem and progenitor cells; in vitro and after transplantation

   Författare :Cecilia Eriksson Linsmeier; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gtv-a; RCAS A -EGFP; transplantation; cell detection; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; GFP-actin; glial differentiation; neuronal differentiation; neurospheres; glial cultures; bFGF; EGF; cell expansion; cortical primordium; MGE; LGE; CNS; stem- progenitor cells;

   Sammanfattning : In this thesis we have used cells dissected from the lateral ganglionic eminence (LGE), the medial ganglionic eminence (MGE), and the cortical primordium of the embryonic mouse forebrain. The tissue was dissected from either i) wild-type mice, ii) green fluorescent protein (GFP)-, or iii) Gtv-a-expressing transgenic mice, and subsequently grown and expanded in vitro using two different protocols.

7. 25. Förstaspråksattrition hos vuxna : Exemplet polsktalande i Sverige

   Författare :Dorota Lubińska; Kenneth Hyltenstam; Michael Sharwood Smith; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; first language attrition; Polish language; Polish immigrants; verbal government; hesitation phenomena; pro-drop parameter; genitive; genitive of negation; reflexive verbs; masculine declension; language attitudes; language use; jezyk polski w Szwecji; atrycja; dwujezycznosc; gramatyka polska; emigracja polska w Szwecji; Bilingualism; Tvåspråkighet; tvåspråkighetsforskning; Bilingualism;

   Sammanfattning : This thesis is concerned with adult L1 attrition in the case of highly-educated long-term Polish immigrants in Sweden. The study sheds light on two classical issues pertaining to L1 attrition, namely what happens to a fully developed mature language system in an immigrant context, and why it happens. LÄS MER
