2. 1. Initiation of spleen contraction resulting in natural blood boosting in humans

   Author : Angelica Lodin; Erika Schagatay; Mats H. Linér; Mittuniversitetet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acclimatization; altitude; apnea; breath-hold diving; hemoglobin; hypercapnia; hypoxia; triggers;

   Abstract : The spleen has been shown to contract in apneic situations in humans as well as in other diving mammals, expelling its stored red blood cell content into circulation. This natural blood boosting may increase the circulating hemoglobin concentration (Hb) by up to 10%, which would enhance the oxygen carrying capacity and likely increase performance. READ MORE

4. 2. Uncemented hip arthroplasty in primary and revision surgery : patterns of bone remodelling and options to influence periprosthetic bone loss

   Author : Mats Salemyr; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Introduction: The incidence of hip arthroplasty surgery in young and active patients is increasing. Consequently, an increasing number of patients will live with hip prostheses for longer periods of time in the future. READ MORE

5. 3. Analysis of Acoustic Absorption with Extended Liner Reaction and Grazing Flow

   Author : Anna Färm; Mats Åbom; Lars Enghardt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; acoustic lining; non-locally reacting; boundary layer; grazing flow; sound field; transfer matrix method;

   Abstract : Acoustic absorbing liners are efficient and commonly used measures to reduce sound levels in many fields of application. The sound reducingperformance of the liners is dependent on the acoustic state, defined by e.g. the flow and sound field interacting with the liner. READ MORE

6. 4. Wear in cone crusher chambers

   Author : Mats Lindqvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cone crusher; modelling; wear; rock crusher; work hardening;

   Abstract : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. READ MORE

7. 5. Innovative noise control in ducts

   Author : Maaz Farooqui; Mats Åbom; Hans Bodén; Tamer Elnady; Jeong-Guon Ih; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Locally resonant materials; slow sound; acoustic impedance; metallic foam; low frequency noise; mufflers; lined ducts; grazing flow; flow duct; impedance eduction.; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : The objective of this doctoral thesis is to study three different innovative noise control techniques in ducts namely: acoustic metamaterials, porous absorbers and microperforates. There has been a lot of research done on all these three topics in the context of duct acoustics. READ MORE
