2. 1. Mechanisms and improvements of cell transplantation for nerve repair

   Author : Kai-Hei Tse; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenchymal stem cells; microporous scaffold; biomaterials; ischemia; cell death; brain derived neurotrophic factor;

   Abstract : Trauma to the nervous system is a frequent clinical problem and new approaches to nerve repair are required. Autologous cell transplantation together with a suitable scaffold material could be used to create a bio-active artificial nerve graft to enhance regeneration. READ MORE

4. 2. Local Structure of Hydrogen-Bonded Liquids

   Author : Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

   Abstract : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. READ MORE

5. 3. Power System Stability Enhancement Using Shunt-connected Power Electronic Devices with Active Power Injection Capability

   Author : Mebtu Bihonegn Beza; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Oscillation Damping POD ; energy storage; Adaptive estimation; Static Synchronous Compensator STATCOM ; Recursive Least Square RLS ; Transient Stability Enhancement TSE ; FACTS; Static Var Compensator SVC ;

   Abstract : Power electronic devices such as Flexible AC Transmission Systems (FACTS), both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the shunt-connected FACTS controllers family, the Static Synchronous Compensator (STATCOM) and the Static Var Compensator (SVC) are two key devices for reinforcing the stability of the AC power system.

6. 4. Assessment of Myocardial Perfusion with Magnetic Resonance Imaging and an Intravascular Contrast Agent

   Author : Tomas Bjerner; Christine Lorenz; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Magnetic resonance imaging; Intravascular contrast agents; Myocardial perfusion; Onkologi; Oncology; Onkologi; radiologi; Radiology;

   Abstract : The intravascular contrast agent NC100150 Injection (Clariscan™) was tested for its ability to induce signal intensity changes in myocardium, both in steady state and during first pass, and thereby demarcating non-perfused myocardium from perfused. Steady state: Ex vivo in pigs and when using 4 mg Fe/kg bodyweight (b.w. READ MORE

7. 5. Control of Energy Storage Equipped Shunt-connected Converter for Electric Power System Stability Enhancement

   Author : Mebtu Bihonegn Beza; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transient stability.; energy storage; recursive least square RLS ; electromechanical oscillation; Signal estimation technique; static synchronous compensator; power oscillation damping POD ;

   Abstract : Flexible AC Transmission System (FACTS) controllers, both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the FACTS controllers family, the Static Synchronous Compensator (STATCOM) is a key device for the reinforcement of the stability in an AC power system. READ MORE
