3. 2. Concentration Difficulties in the School Environment - with focus on children with ADHD, Autism and Down's syndrome

   Författare :Catrin Tufvesson; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Down s syndrome; concentration; children; building process; ADHD; the Human Environment Interaction-model; individual adjusment; learning; indoor environment; school environment; Psykologi; Psychology; Humanities; Humaniora; autism;

   Sammanfattning : The overall aim of this thesis was to identify environmental factors that affect children with ADHD, autism, and Down's syndrome and their ability to concentrate in their learning environment at school. The issue of this research is not to dismiss any of the additional resources these children are in need of; instead it is to suggest how to arrange learning environments in the most supportive way possible based on the initial needs of these children.

4. 3. Bird orientation: external cues and ecological factors

   Författare :Johan Bäckman; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tracking radar; Emlen funnel.; Animal ecology; Djurekologi; oscillatory orientation; roosting flight; scatter; concentration; heading; cue calibration; light dependent; magnetoreception; subcutaneous fat stores; body condition; energetics; geomagnetic field; visual cues; orientation; birds; migration;

   Sammanfattning : Birds are generally capable of accurate orientation. In this thesis I present studies about the external cues and the ecological factors that influences bird orientation. A multitude of environmental cues are used to select and maintain a proper direction. LÄS MER

7. 5. Chloride Homeostasis in Central Neurons

   Författare :Tushar Yelhekar; Staffan Johansson; Michael Druzin; Merab Kokaia; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chloride concentration; current-voltage relation; interpolation; voltage ramp; reversal potential; [Cl–]i recovery; KCC2; extracellular matrix; GABAA receptor; chloride leak conductance; neurosteroid; fysiologi; Physiology;

   Sammanfattning : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. LÄS MER
