2. 1. Deaf children in communication : a study of communicative strategies used by deaf children in social interactions

   Author : Gunilla Preisler; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Deaf children; sign language; oral training; communicative strategies; child-child interaction; descriptive; video recordings; detailed analyses; nonverbal behavior; verbal behavior;

   Abstract : This is a descriptive study of communicative strategies used by fifteen deaf preschool children. Five of the children had early sign language experience (ESL), while ten had late sign language experience (LSL). Seven of the LSL children had been orally trained. READ MORE

4. 2. Applying the Pump and Leak Hypothesis. An experimental and theoretical investigation of the principles of ion regulation and excitability in the crustacean stretch receptor neuron

   Author : Sten Theander; Människan i rörelse: hälsa och rehabilitering; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; lobster; stretch receptor neuron; leak current; Q-current; K-Cl cotransporter; A-current; mathematical model; excitability; GABA channel; neurophysiology; ion regulation; neuropsykologi; Neurologi; neurofysiologi;

   Abstract : An invertebrate nerve cell preparation, the lobster stretch receptor neuron, was investigated with respect to maintenance of its resting voltage, intracellular ion concentrations and excitability using voltage clamp technique and ion-selective microelectrodes. It was found that the resting voltage (-65 mV) of microelectrode impaled cells is caused by (a) a homogenous population of K+ channels which we denoted as leak channels (b) an electrogenic and voltage-dependent Na-K pump current and (c) an inward microelectrode-induced "impalement" current carried mainly by Na+.

5. 3. Geological development of the East African coastal basin of Tanzania

   Author : Samson Mpanda; Ole Veibaeck; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; seismic methods; seismic stratigraphy; multichannel seismic recordings; tectonic development; Karoo; Mesozoic; Tertiary; East Africa; Tanzania; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

   Abstract : The East African coastal basin of Tanzania, which is characterised by an extensional tectonic style, is located along the passive continental margin of the western Indian Ocean. The present study is concerned with the Mafia Island and the Mafia Channel which together form a subbasin within the north-south elongated coastal sedimentary basin of Tanzania. READ MORE

6. 4. Multi-Channel Acquisition and Visualization of the Dolphin Echolocation Beam – Instrumentation Design and Bioacoustic Results

   Author : Josefin Starkhammar; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Toothed whales (Odontocetes) use echolocation to navigate and find food in dark or murky waters. A wide range of innovative studies has since the 1960:s been used to characterize their echolocation beam and map out their echolocation skills. READ MORE

7. 5. Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces

   Author : Palmi Thor Thorbergsson; Institutionen för elektro- och informationsteknik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular neural recordings; wireless brain-machine interfaces; signal modeling; data reduction; compression;

   Abstract : Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. READ MORE
