1. 1. Negative symptoms, repetitive transcranial magnetic stimulation and heart rate variability in schizophrenia and depression

   Författare :Johan Bengtsson; Robert Bodén; Jonas Persson; Erik Olsson; Caroline Wass; Jimmi Nielsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; negative symptoms; psychotic disorders; affective disorders; non-invasive brain stimulation; transdiagnostics; psychometrics; autonomic nervous system; Psychiatry; Psykiatri;

   Sammanfattning : Negative symptoms comprise anhedonia, avolition, and blunted affect. Although first described in schizophrenia, these symptoms share phenomenology with the depressive state. Pharmacological treatment has not been successful in reducing negative symptoms. LÄS MER

3. 2. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

   Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

   Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

4. 3. Control of EGR and VGT for emission control and pumping work minimization in diesel engines

   Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Tore Hägglund; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean value modeling; Oxygen fuel ratio; EGR-fraction; System analysis; Sign reversal; PID-control; European Transient Cycle; Automatic control; Reglerteknik;

   Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

5. 4. Identification of candidate genes involved in Mercury Toxicokinetics and Mercury Induced Autoimmunity

   Författare :Hammoudi Alkaissi; Per Hultman; Said Havarinasab; Peter Söderkvist; Jesper Bo Nielsen; Johan Rönnelid; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : BACKGROUND: Autoimmune diseases require the involvement and activation of immune cells and occur when the body builds up an immune response against its own tissues. This process takes place due to the inability to distinguish self-antigen from foreign antigen. Systemic autoimmunity represents an important cause of morbidity and mortality in humans. LÄS MER

7. 5. Failure Prediction of Complex Load Cases in Sheet Metal Forming : Emphasis on Non-Linear Strain Paths, Stretch-Bending and Edge Effects

   Författare :Alexander Barlo; Tobias Larsson; Mats Sigvant; Md. Shafiqul Islam; Johan Pilthammar; Karl Brian Nielsen; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sheet Metal Forming; Failure Prediction; Non-Linear Strain Paths; Stretch-Bending; Edge Effects; Maskinteknik; Mechanical Engineering;

   Sammanfattning : With the increased focus on reducing carbon emissions in today’s society, several industries have to overcome new challenges, where especially the automotive industry is under a lot of scrutiny to deliver improved and more environmentally friendly products. To meet the demands from customers and optimize vehicles aerodynamically, new cars often contain complex body geometries, together with advanced materials that are introduced to reduce the total vehicle weight.
