2. 6. Numerical Investigation of Rotating and Stratified Turbulence

   Author : Enrico Deusebio; Erik Lindborg; Johan Nilsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geostrophic turbulence; stable stratification; rotation; wall-bounded turbulence; gravity waves; atmospherical dynamics; direct numertical simulations; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

   Abstract : Atmospheric and oceanic flows are strongly affected by rotation and stratification. Rotation is exerted through Coriolis forces which mainly act in horizontal planes whereas stratification largely affects the motion along the vertical direction through buoyancy forces, the latters related to the vertical variation of the fluid density.

4. 7. Congenital muscular torticollis

   Author : Anna Öhman; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; craniofacial asymmetry; rotation; lateral flexion; muscle function; infants; reference values; torticollis; early motor milestones; stretching treatment; physiotherapy;

   Abstract : Aim: The purpose of these studies was to undertake a survey of functional and cosmetic status in children treated for congenital muscular torticollis (CMT), to examine validity and reliability of the Muscle Function Scale (MFS), to find reference values for rotation and lateral flexion of the neck and muscle function of the lateral flexors in the neck for the normally developing infant, to investigate if infants with CMT are at higher risk of achieving the early motor milestones later compared to a control group of healthy infants and to investigate if treatment duration is affected when stretching is carried out by an experienced physiotherapist compared to parents. Methods: Range of motion (ROM) in neck rotation was measured with an arthrodial protractor. READ MORE

5. 8. Sar Remote Sensing of Sea Ice: Towards automatic extraction of geophysical information

   Author : Yan Sun; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; deformation; SAR; segmentation; cross-correlation; rotation; optical flow; motion detection;

   Abstract : Synthetic Aperture Radar (SAR) images from the ERS-1 satellite have great potential for sea ice remote sensing due to its independence of daylight and clouds. The very high data rate of SAR (over 100 million bits per second) results in an enormous volume of data that threatens the ability of human interpreters. READ MORE

6. 9. Drift-Type Waves in Rotating Tokamak Plasma

   Author : Elina Asp; Vladimir Pavlenko; Hans Nordman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; fusion; plasma; tokamak; rotation; drift; ship; ITG; TE; Landau; Te Ti; hot-electron; confinement; stiffness; Weiland; Rymd- och plasmafysik; Space physics; Rymdfysik; Space and Plasma Physics; rymd- och plasmafysik;

   Abstract : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. READ MORE

7. 10. Neuroprotective and regenerative actions of GDNF and neurturin on nigral dopamine neurons in rat models of Parkinson’s disease – Prospects for clinical use of neurotrophic factors in neurodegenerative disorders

   Author : Carl Rosenblad; Neurobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; striatum; substantia nigra; dopamine; GDNF; neurturin; sprouting; neuroprotection; forelimb akinesia; rotation; tyrosine hydroxylase; transplantation; Neurologi; neuropsykologi; neurofysiologi;

   Abstract : Parkinson’s disease is characterized by progressive degeneration of the nigrostriatal dopamine system, which results in tremor, rigidity, akinesia and postural abnormalities. New therapeutic strategies are aimed at halting the neurodegenerative process or restoring the system by transplantation of fetal dopamine neurons. READ MORE
