When differential-algebraic equations of index 3 or higher are solved with backward differentiation formulas, the solution in the first few steps can have gross errors, the solution can have gross errors in the first few steps, even if the initial values are equal to the exact solution and even if the step size is kept constant. This raises the question of what are consistent initial values f
Popular Abstract in Swedish Celiaki, även kallat glutenintolerans, är en tarminflammation orsakad av vissa sädesslag i kosten och förekommer hos både barn och vuxna. Sjukdomen drabbar ca 1% av befolkningen i västvärlden och betraktas som en av de vanligaste kroniska sjukdomarna bland svenska barn. Många individer med sjukdomen är oupptäckta och kan bara hittas via s.k. screening, d.v.s. att man leObjectives: Celiac disease is a common immune mediated enteropathy strongly associated with HLA-DQB1*02 (DQ2), *0302 (DQ8), or both and the presence of tissue transglutaminase autoantibodies (tTGA). Prevalence studies have revealed that most affected individuals go undetected because of subclinical signs or being asymptomatic rendering screening a method for identification. However, less is known
OBJECTIVE: To assess the outcome of vacuum-assisted wound closure (VAC(®)) therapy for infected bypass grafts. METHODS: A retrospective 7-year review of patient records from 2004 to 2011 of all patients receiving VAC(®) therapy for infected bypass grafts. RESULTS: Thirty-seven patients with 42 wounds and 45 infected bypass (28 synthetic) grafts received VAC(®) treatment. Two serious bleeding e
The potential of Fe-V-oxide catalysts for use in methanol oxidation is explored. Our results show that although FeVO4 is active and selective for formaldehyde formation, it is not completely stable towards volatilization under reaction conditions. Attempts to stabilize Fe-V-oxide were made using titania, alumina and silica supports. However, we observe that although some stabilization is achieved
Background This study identifies a promising, new focus for the crisis management research in the health care domain. After reviewing the literature on health care crisis management, there seems to be a knowledge-gap regarding organisational change and adaption, especially when health care situations goes from normal, to non-normal, to pathological and further into a state of emergency or crisis.
A widespread and flexible use of robots in rapidly changing working environments could be greatly enhanced by human-robot interaction and collaboration. Humans and robots have complementary skills. The robotic worker can relieve the human from repetitive work, and the human can make robot deployment easier by managing nonstandard or particularly skilful operations. Such a scenario, however, requir
A carbon nanotube forest provides a unique non-stick surface for nanomanipulation, as the nanostructuring of the surface allows micro- and nanoscale objects to be easily removed after first being deposited via a liquid dispersion. A common problem for smooth surfaces is the strong initial stiction caused by adhesion forces after deposition onto the surface. In this work, carbon nanotube forests fa
The field of tissue engineering has a growing need for suitable scaffold materials to become attractive as a clinical therapy. To use a completely autologous construct to repair a damaged or diseased tissue is an appealing thought. As a model system, two types of scaffolds were prepared from biological fluids: blood and plasma. The prepared scaffolds formed a macroporous structure with elastic mec
Popular Abstract in Swedish Att det ska råda fri rörlighet för arbetstagare/personer och deras familjemedlemmar är en grundläggande princip i EU-rätten. I artikel 48 i Fördraget om Europeiska unionens funktionssätt (EUF) ges EU befogenhet att vidta åtgärder för att koordinera, samordna, de olika nationella sociala trygghetssystemen inom EU. Förordning 1408/71 och dess ersättare förordning 883/2004This doctoral thesis examines the Swedish parental benefit in relation to the EU principles on free movement, namely the Treaty provisions on free movement for workers and Union citizens, and more specifically, the legislation on coordination of social security benefits – Regulation 1408/71 and its successor Regulation 883/2004. The rights enshrined in the Treaty on the Functioning of the European
Economical grade changes are considered for a Borealis Borstar polyethylene plant model, incorporating two slurry-phase reactors, one gas-phase reactor and a recycle area with three distillation columns. The model is constructed in the Modelica language and the JModelica.org platform is used for opti- mization. The cost function expresses the economical profit during a grade change and is formulat
For vehicles using grid power to charge the battery, traction circuit components are not normally engaged during the charging time, so there is a possibility to use them in the charger circuit to have an on-board integrated motor drive and battery charger. An isolated high-power three-phase integrated motor drive and charger based on a split-phase permanent magnet motor is presented in this paper.
Nynas Petroleum is one of the world´s largest producers of naphthenic specialty oils. They have refineries in several parts of the world and their largest production facility is situated in Nynäshamn, Sweden. They also have oil depots in all continents and their largest depot is located in Antwerp, Belgium. In the beginning of 2007 Nynas introduced a new type of transformer oils, called Nova grade
This master thesis is a project initiated by the fourth-party logistics company UBQ. They aim to take over the management of the transportation and storage of raw material for Volvo Car Body Components, VCBC, in Olofström. VCBC wants to remove the storage of raw material in the production area. The thesis aims to link the both companies’ requests together by describing the current situation, the s
The writing of a business plan has become increasingly more highlighted in the academic world during the last few years as courses are being taught on the subject and a number of competitions have been started. Lund Institute of Technology co-organises an annual business plan competition called Venture Cup in order to encourage students and other participants to get into entrepreneurship. People a
Syftet med uppsatsen var att jämföra antalet kvinnliga respektive manliga författare som elever i den senare delen av grundskolan får kännedom om. För att undersöka det använde jag mig av läroböcker i svenska riktade till årskurs 7-9. Antalet författare i alla undersökta läroböcker räknades samt viktades på olika sätt. Först efter hur många gånger de nämndes i läroböckerna och därefter efter hur m
The thesis is done for the company Gambro which manufactures dialysis products worldwide. The idea of this thesis is to investigate weaknesses of the communication protocol which is used in one of the Gambro dialysis machines, Prismaflex and thereby investigate opportunities to improve the system by using other protocols. The thesis is divided into three major parts. They are the study of Prismafl
Problem discussion: To be more competitive, Trading Area Wood is working on developing their suppliers in efficiency projects. However, they find it hard to motivate their suppliers to take part in the projects. Therefore, they need a way to show the suppliers the positive effects of participating in the efficiency projects. Moreover, Trading Area Wood has troubles to predict the economical outcom
