In this master's thesis I study the meaning of the concept of circular migration and the policy discussion and interpretation process regarding the formulation of policies that promote circular migration. I use theories on global political order to analyze how the policy discussion on circular migration relates to concepts such as sovereignty and universal rights. I have chosen to base my stud

Denna uppsats har via en rättsdogmatisk metod undersökt gällande rätt avseende nödvärn och nödvärnsexcess vid överfall. Den faktiska rättstillämpningen i underrätterna har inte berörts. Rätten till försvarsvåld gentemot brottsliga angrepp tillkommer dels den angripne, dels envar som befinner sig på platsen för angreppet. Denna rätt regleras i nödvärnsstadgandet i 24 kap. 1 § BrB. Skulle omfattnin

As a result of the terrorist attacks on America on September 11, 2001 air security regulations have become stricter and people’s perception of risks related to flying and terror has changed. The primary objective of this master thesis is to examine how terror threats against civil aviation are handled by passengers and decision makers and to study opinions of security measures. The methods used in

Business Continuity Management (BCM) is in many respects a technically oriented field. The technical aspects of BCM are of great importance, however they become meaningless if not used and managed properly. Without adequate human and organizational conditions, there is a risk that BCM does not take the decisive step from solely comprising well-documented business continuity plans, to also generati

Only well-maintained railway systems can function without severe interruptions. However,maintenance activities can themselves cause train delays if they conflict with trainmovements. Trackwork refers to maintenance performed on a railway track. This studyaims to investigate the effect of trackwork on train delays in Sweden. It presents a logisticregression analysis based on more than 225,000 plann

Pivotal anatomical innovations often seem to appear by chance when viewed through the lens of the fossil record. As a consequence, specific driving forces behind the origination of major organismal clades generally remain speculative. Here, we present a rare exception to this axiom by constraining the appearance of a diverse animal group (the living Ophiuroidea) to a single speciation event rather

Autoantigen discovery is a critical challenge for the understanding and diagnosis of autoimmune diseases. While autoantibody markers in current clinical use have been identified through studies focused on individual disorders, we postulated that a reverse approach starting with a putative autoantigen to explore multiple disorders might hold promise. We here targeted the epidermal protein transglut

Superantigens (SAgs) are bacterial enterotoxins produced by Staphylococcus aureus. Staphylococcal enterotoxin type A (SEA), a staphylococcal superantigen, has been shown to bind to the cytokine signalling receptor glycoprotein 130 (gp130). The structural details, as well as the exact physiological role of this interaction, remain unclear. Here, we describe the structural details of the SEA–gp130 c

BACKGROUND: Costs and a low total number of cases may be obstacles to the successful implementation of a paediatric robotic surgery programme. The aim of this study was to evaluate a decade of paediatric robotic surgery and to reflect upon factors for success and to consider obstacles.MATERIALS AND METHODS: All children operated on with robotic-assisted laparoscopic surgery between 2006 and 2016 w

This review presents the status and outlook for shared energy systems (SES) and fifth-generation district heating and cooling (5GDHC). It provides an overview of the technical and functional knowledge encompassing design and development, operational and system architecture, and control and decision support systems of these technologies. The review also presents different tools and models found in

Cities across the world are increasingly labelling themselves as smart in one way or another. At the same time, this smartness appears amorphous or invisible in its built urban environment. Critical researchers writing on the smart city regularly express confusion or exasperation about precisely the difficulty to locate the smart in the city. Visibility of the smart city is not a given. This artic

This report contains the student papers describing the projects in the 2017 course Projects in Automatic Control (FRTN40). The course is given annually by the Department of Automatic Control, Lund University, during the second half of the fall semester, with the possibility of projects starting at other times upon agreement. It is an advanced level course, giving 7.5 ECTS credits. The main purpos
