2. 1. Clustering Architectures: The Role of Materialities for Emerging Collectives in the Public Domain

   Author : Jesper Magnusson; Institutionen för arkitektur och byggd miljö; []
   Keywords : HUMANIORA; HUMANITIES; Urban design; public life; public space; collective space; everyday life; actor-network theory; territoriality; social interaction; nonhuman agency; material culture;

   Abstract : This thesis is a study of social life, addressing issues concerning how and by what means people meet in urban public space. The main aim of this thesis is to is to investigate how certain artefacts and architectural features support the formation and temporal stabilisation of heterogeneous clusters and collectives, and thus, in order to the development of conceptual tools that can contribute to a more refined description and analysis of the role of architecture and artefacts for urban public life [a very long sentence…].

4. 2. Quality of life in men with inguinal hernia and outcome after three different mesh techniques

   Author : Jesper Magnusson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Inguinal hernia repair (IHR) is a very common surgical procedure with approximately 16 000 procedures performed every year in Sweden. Previously, recurrence after IHR was a major concern, but with the introduction of the use of a synthetic mesh, recurrence rates are low today (1-2%). READ MORE

5. 3. On the design of hybrid DC-breakers consisting of a mechanical switch and semiconductor devices

   Author : Jesper Magnusson; Göran Engdahl; Staffan Norrga; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DC; circuit breaker; hybrid breaker; DC systems; DC; brytare; hybridbrytare; likström;

   Abstract : The interest of using direct current in networks for both transmission and distribution of power is increasing due to the higher efficiency compared to the alternating current used today. As no natural zero crossings exist in direct current, the interruption of fault currents becomes a challenge. READ MORE

6. 4. Studies on Current Commutation in Hybrid DC-breakers

   Author : Jesper Magnusson; Göran Engdahl; Magne Runde; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commutation; Hybrid DC-breakers; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Compared to conventional AC-circuit breakers, a DC-breaker has to act fast and force the current down to zero. Many different DC-breaker topologies are available, and this thesis is focused on the hybrid DC-breaker comprising a mechanical switch and high power semiconductors. READ MORE

7. 5. Inner ear proteomics and barriers : Clinical and experimental findings

   Author : Jesper Edvardsson Rasmussen; Göran Laurell; Per Olof Eriksson; Helge Rask-Andersen; Jonas Bergquist; Måns Magnusson; Uppsala universitet; []

   Abstract : Hearing is important in many aspects of life, including communication, assessing one’s surroundings, entertainment and social interaction. Hearing loss is common and according to the Global Burden of Disease Study, 5% of the global population require hearing rehabilitation (1). READ MORE
