2. 1. Evaluating the performance of TEWA systems

   Author : Fredrik Johansson; Göran Falkman; Lars Karlsson; Lars Niklasson; Martin Holmberg; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; air defense; information fusion; performance evaluation; threat evaluation; TEWA; weapon allocation; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Datalogi; Computer and Systems Science; Teknik;

   Abstract : It is in military engagements the task of the air defense to protect valuable assets such as air bases from being destroyed by hostile aircrafts and missiles. In order to fulfill this mission, the defenders are equipped with sensors and firing units. To infer whether a target is hostile and threatening or not is far from a trivial task. READ MORE

4. 2. Impact of Water-Level Variations on Slope Stability

   Author : Jens Johansson; Lars Johansson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Abstract : Waterfront-soil slopes are exposed to water-level fluctuations originating from either natural sources, e.g. extreme weather and tides, or from human activities such as watercourse regulation for irrigation, freshwater provision, hydropower production etc. READ MORE

5. 3. Risk markers and incidence of atrial fibrillation in northern Sweden

   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; atrial flutter; incidence; provoking factors; types of atiral fibrillation; stroke risk; alcohol consumption; problem drinking; weight; height; weight change; normal blood pressure; high normal blood pressure; Förmaksflimmer; förmaksfladder; incidens; provocerande faktorer; typer av förmaksflimmer; strokerisk; alkoholkonsumtion; alkoholproblem; vikt; längd; viktförändring; normalt blodtryck; högt normalt blodtryck; medicin; Medicine;

   Abstract : Background: Atrial fibrillation (AF) is the most common clinically significant arrythmia with a prevalence of approximately 3% in the general population. Less is known about the incidence of AF. In order to reduce the incidence of AF, it is of essence to identify modifiable risk factors for the disease. READ MORE

6. 4. Biomarkers and risk of intracerebral hemorrhage : population-based studies in northern Sweden

   Author : Kristina Johansson; Marcus Lind; Lars Johansson; Jan-Håkan Jansson; Arne Lindgren; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracerebral hemorrhage; hemorrhagic stroke; factor XII; D-dimer; von Willebrand factor; ABO blood groups; phosphatidylethanol; alcohol; risk markers; biomarkers; Medicine; medicin;

   Abstract : BackgroundIntracerebral hemorrhage (ICH) is a disease associated with a high morbidity and mortality and treatment options for the condition are limited. Even though an ICH event usually comes as a surprise to the affected individual, pathogenetic processes often have occurred before the sudden ICH event and may have preceded disease onset by years.

7. 5. Oxygen-reducing enzymes in coatings and films for active packaging

   Author : Kristin Johansson; Lars Järnström; Caisa Johansson; Leif J. Jönsson; Jose M. Lagaron; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active packaging; food packaging; oxygen scavengers; oxygen-reducing enzymes; dispersion coating; biopolymers; Chemical Engineering; Kemiteknik;

   Abstract : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. READ MORE
