1. 16. Improved energy efficiency in double disc chip refining

   Författare :Dino Muhic; Per Engstrand; Lars Sundström; Mats Ullmar; Christer Sandberg; Hans Höglund; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical pulping TMP ; double disc refining; high intensity; Chemical engineering; Kemiteknik;

   Sammanfattning : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. LÄS MER

3. 17. Cannabis discourses in contemporary Sweden : Continuity and change

   Författare :Josefin Månsson; Mats Ekendahl; Alexandra Bogren; Sveinung Sandberg; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cannabis; Sweden; discourse; social construction; prohibition; legalization; de-criminalization; internet; online; media; professional; symposia; Social Work; socialt arbete;

   Sammanfattning : The aim of this thesis is to study how cannabis is constructed in contemporary Sweden, which policy responses are promoted as rational, and how international cannabis trends are received in this context. The four papers are the result of analyzing empirical material from three different sub-studies: 1) a qualitative study of online discussions about cannabis and drug policy, 2) a qualitative and comparative study of print media articles from 2002 and 2012, and 3) a qualitative study of oral presentations from cannabis information symposia.

4. 18. Managing Variable Patient Flows at Hospitals

   Författare :Olle Olsson; Håkan Aronsson; Erik Sandberg; Mats Abrahamsson; Pamela Mazzocata; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Healthcare is a large industry faced with major challenges, such as decreasing inpatient bed numbers and increases in the share of elderly people, which require improved efficiency and effectiveness. The organisation of hospitals normally comprises highly specialised clinical departments, through which patient flows are managed. LÄS MER

5. 19. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator

   Författare :Amir Sattari; Ivo Martinac; Mats Sandberg; Dirk Müller; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle Image Velocimetry PIV ; experimental study; structured light 3D scanning system; ventilation; varying flow rate; room model; wall-mounted radiator; air; water; flow; Particle Image Velocimetry PIV ; experimentell studie; scanningsystem för strukturerat 3D-ljus; ventilation; varierande tilluftsflöde; rumsmodell; väggmonterad radiator; Engineering Mechanics; Teknisk mekanik; Byggvetenskap; Civil and Architectural Engineering; Energy Technology; Energiteknik;

   Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER

7. 20. In-Plane Shear Modulus of Cross-Laminated Timber

   Författare :Jonas Sharifi; Sven Berg; Dick Sandberg; Mats Ekevad; Reinhard Brandner; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

   Sammanfattning : Cross-laminated timber (CLT) is a building component used in walls, floors, roofs, or beams in a building. The advantages of using CLT as a building component are, among others, its high load-carrying capability and the possibility of pre-fabrication. LÄS MER
