   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asset management; condition monitoring; failure rate; failure rate modeling; Electrical Engineering; Elektro- och systemteknik;

   Abstract : A set of vital societal functions such as health and safety are necessary for today's society to function and to secure the life of its individuals. Infrastructure is required to provide and maintain these functions. READ MORE

4. 2. Living Away from Blessings : School Failure as Lived Experience

   Author : Carina Henriksson; Solveig Hägglund; Växjö universitet; []
   Keywords : school failure; lived experience; lived experience description.; temporality; spatiality; relationality; cognitive inadequacy; behavioral deficiency; the hidden curriculum; hermeneutic phenomenology; phenomenology of practice; Pedagogik; Pedagogics;

   Abstract : This dissertation seeks to unveil and describe students’ experiences of school failure. Traditionally, research in the field has tended to approach school failure from a societal perspective, often construing school failure as a drop-out problem. READ MORE

5. 3. Mineralocorticoid receptor antagonists in heart failure : exploring the gap between guideline-directed medical therapy and real-world practice

   Author : Anna Jonsson Holmdahl; Krister Lindmark; Helena Norberg; Ellinor Bergdahl; Fredrik Valham; Niklas Bergh; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; Mineralocorticoid receptor antagonists; estimated glomerular filtration rate; hyperkalemia; impaired renal function; worsening renal function; guideline-directed medical therapy; kardiologi; Cardiology;

   Abstract : Heart failure is the possible end-result of a variety of different diseases, where ischemic heart disease and hypertension are the most common causes in high income countries. In Sweden, heart failure has a prevalence of 2% in the adult population and rises to over 10% among people over 70 years of age. The 5-year all-cause mortality is about 50%. READ MORE

6. 4. Condition-based Failure Rate Modelling for Individual Components in the Power System

   Author : Jan Henning Jürgensen; Patrik Hilber; Lars Nordström; Thomas Welte; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asset management; condition monitoring; diagnostic measures; failure rate; failure rate modeling; transformer diagnostics; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The electrical power grid is one of the most important infrastructures in the modernsociety. It supplies industrial and private customers with electricity and supportsother critical infrastructures such as the water supply. Thus, it is significant that the power grid is a reliable system.
