2. 1. CFD of Duct Acoustics for Turbocharger Applications

   Author : Emma Alenius; Mats Åbom; Laszlo Fuchs; Federico Piscaglia; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aero acoustics; Large Eddy Simulation; IC-engines; 1D models; turbocharger; orifice plate; Acoustics; Akustik; Fluid mechanics; Strömningsmekanik;

   Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. In this work the main focus is the turbocharger compressor and a discussion of turbocharger acoustics and earlier work within the area is presented, giving an insight into its sound generating mechanisms and the damping effect it has on pressure pulses, i.

4. 2. Flow Duct Acoustics : An LES Approach

   Author : Emma Alenius; Mats Åbom; Laszlo Fuchs; Oliver Paschereit; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aero-acoustics; duct-acoustics; sound generation; acoustic scattering; acoustic-flow interaction; LES; IC-engines; orifice plate; confined jet;

   Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. Simulations are an important tool for enhanced understanding; they give insight into the flow-acoustic interaction in components where it is difficult to perform measurements. READ MORE

5. 3. Treatment Response in Psychotic Patients in a Naturalistic Setting : Classification, Genes, Drugs, Insight and Social Networks

   Author : Malin Alenius; Margareta Hammarlund-Udenaes; Per Hartvig Honoré; Leif Lindström; Lena Flyckt; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PHARMACY; FARMACI;

   Abstract : Many patients with psychotic symptoms respond poorly to treatment. Various approaches have been made to classify these patients according to treatment response. However, existing classifications have been criticized for various reasons and a new classification system is needed. READ MORE

6. 4. Conditions for care : factors in the nurse work environment related to safe and high quality care in acute care hospitals

   Author : Lisa Smeds Alenius; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Shortages of registered nurses (RNs) intensify challenges for healthcare service providers in matching an increasing demand for care with a sufficient healthcare workforce. Poor working conditions have been recognized to often precede RNs’ decision to leave the profession prematurely. READ MORE

7. 5. Heart rate variability and pacemaker treatment in children with Fontan circulation

   Author : Jenny Alenius Dahlqvist; Annika Rydberg; Urban Wiklund; Jaana Pihkala; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital heart disease; Fontan circulation; heart rate variability; pacemaker; sinus node dysfunction; pediatrik; Pediatrics; kardiologi; Cardiology;

   Abstract : Background: Fontan surgery is performed in children with univentricular heart defects. Arrhythmias are frequent complications, occasionally requiring pacemaker treatment. Previous data regarding indications and risk factors for pacemaker treatment in Fontan patients is limited and conflicting. READ MORE
