This report contains a theoretical study concerning composite construct design with steel and concrete and its mechanical and thermal interaction. The two primary advantages with this composition are the increase of the load-carrying capacity and its fire resistance. Composite construct elements are often used in the building process and there are several companies that offer a complete framework

Calculated deformations in glulam beams caused by moisture are based on linear moisture profile, this does not reflect reality. This report contains of a study where the moisture induced deformations are measured in three different test setups, simulating more realistic moisture exposure. After the beams are seasoned in RH 30 and 95 % the climate was changed, one group was in a moistening phase an

Today´s society depend on electric energy, in nuclear power plants this can be produced. Each nuclear reactor is situated inside a concrete containment reinforced with a post-tensioning system. The aim of this report is to analyse the state of the post-tensioning systems at Ringhals nuclear power plant. The purpose of a containment is to protect the outside world if an accident should occur. Tight

The purpose of this research was to determine how much the strength reduces in a slant nailed connection, which was examined for horizontal loads between stud and bottom plate in an infill wall. Slant nailing is commonly used in the workplace and is an alternative to metal plate connectors as they are both more expensive and more time consuming. However, there are no Swedish or European standards

This paper presents two methods of shear capacity design in two-dimensional membrane elements. The aim in this thesis is to find a method who calculates one resulting transeverse reinforcement instead of two. A procedure (Unified Shear Theory by Collins and Mitchells) is presented for design of transverse reinforcement in two-way concrete slabs. This procedure is compared to the Swedish procedure

Today, the knowledge about ice forces in Sweden is uncertain. Certain guidelines have been developed according to RIDAS to determine ice forces when constructing dams, piers etc. In this thesis an environmental model has been developed to predict thermal ice pressures. The inputs for the model are; a) the mean daily air temperature for each day of the year; b) the snow cover depth. The mean daily

I samband med Södersjukhusets jobbannons från februari i år där Tv-seriesnygga sjuksköterskor söktes dök frågan upp huruvida arbetsgivaren kan ställa krav på arbetstagarnas utseende. Vilken rätt arbetsgivare faktiskt har att ställa krav på arbetstagarnas och arbetssökarnas utseende finns inte direkt uttryckt i lag. Istället finns det lagar och praxis som snarare hindrar arbetsgivaren att ställa vi

Foreign trade is an important part in Africa’s internationalization process. In order to assess the entrepreneurial possibilities in Sub Saharan Africa, one can look at firm’s probability of entering the export market. The aim of this paper is to examine the importance of sunk costs of exporting for Sub Saharan African firms. This is done by assessing the importance of past export performance on t

This report contains an analysis of major fatal fires. The analysis is carried out using the methodology in the conference article "Learning from real fire incidents - A methodology for case studies." The methodology is used to systematically introduce, analyse and draw joint conclusions of the various events. The aim is to find the key factors leading to the development of the events, i

Med det naturliga åldrandet följer ofta många hälsoproblem. Urininkontinens förekommer i alla åldrar, men problemet ökar med stigande ålder. Syftet med studien var att undersöka prevalens och svårighetsgrad av urininkontinens, relaterat till fysisk aktivitet och ADL hos äldre. Syftet var även att studera om det föreligger några eventuella könsskillnader. Resultatet visade att 266 (23 %) av 1141 be

This project is an collaboration with Höganäs AB, with the goal to design a light vehicle that meets the demands of the modern commuter, in function as well as in quality and sustainability. The result of the project is a light scooter using Höganäs E-Drive system, with Hydrogen Fuel Cells as the power source. The vehicle is designed to be adaptable to the user, while still being comfortable and e

Several studies have suggested effective climate information outreach is invaluable for smallholders’ decision-making on farming operations as a viable strategy to cope with extreme effects of climate change and increased productivity. Starting with the review of development and agriculture issues, this thesis seeks to investigate the knowledge and practice of improved agro-ecological techniques a

Bakgrund: Enligt statens beredning för medicinsk utvärdering uppskattas 1,8 miljoner av den vuxna befolkningen i Sverige ha förhöjt blodtryck. Grunden för behandling av högt blodtryck är förändring av levnadsvanor. Nationella riktlinjer för sjukdomsförebyggande metoder (2011) anger att rådgivning ska vara grunden för förändring av ohälsosamma levnadsvanor. För att kunna ge bästa möjliga rådgivning

De senaste årens ekonomiska kriser har tvingat många företag att rationalisera och dra ned på anställda. Genom att endast behålla en kärna av egna anställda kan företag anpassa sig efter toppar och dalar i konjunkturen genom att hyra in personal vid behov. Bemanningsföretag är företag som hyr ut sin personal till kundföretag. Kundföretaget får i uthyrningskontraktet arbetsledningsrätt över den inh

Bemanningsbranschen är idag starkt etablerad på den svenska arbetsmarknaden. Dess snabba utveckling och expandering har dock medfört frågetecken kring den trepartsrelation som skapas mellan kundföretaget, bemanningsföretaget och den anställda och hur denna trepartsrelation hanteras i svensk diskrimineringslagstiftning. Uppsatsen tar avstamp i en promemoria från Näringsdepartementet som belyser deEmployment agencies, as an industry, are well established in the contemporary Swedish labor market. Its vast expansion over the last few decades however, raises questions as to how Swedish discrimination regulations, handle the three-party relationship that occur between the employer, the employee and the host company. The purpose of the essay is to firstly, analyze whether Swedish labor law regu

Populärvetenskaplig sammanfattning Självfästande Filmjölk Många upplever vid frukostbordet att det är bökigt och kladdigt att hälla ur all filmjölk ur paketet, så när konsumenten anser att förpackningen är tom finns det cirka 10% kvar av produkten. Detta är något som gemene man inte reflekterar över. Eftersom en del av filmjölken fäster på förpackningens insida så innebär det att det slängs mängdeCaseins are the most abundant proteins in milk products and are thought to be crucial for many of its properties, like texture, viscosity, but also adhesion to packaging materials. The latter leads to a product loss of about 10%, and economical and environmental problems, and its molecular origin is here investigated from the interaction between β-casein and dierent surface materials. A theoretica

General rules for rational design as well as prediction of tertiary structure and functionality of a protein can be described by investigating the interactions and the role of particular amino acids in protein structure. Mutagenesis has been used commonly to generate stable variants, with an ultimate goal to unravel the rules of protein stability and folding. Besides, reconstitution of dissected p

Populärvetenskaplig sammanfattning Metal-organic frameworks (MOFs) är kristaller med små hållrum eller porer som man sedan kan sätta dit en dörr där den kan öppnas eller stängas. Denna dörren är en organisk förening som kan bli krökt när man lyser med en speciel lampa. När kristallen utsätts för t.ex. vätgas kan kristallen sedan stänga dörrarna med hjälp av speciel lampa och då bevaras gasen inutiMetal-organic frameworks (MOFs) are micro porous crystalline solids consisting of inorganicorganic compounds, and have been developed rapidly in design and synthesis due to their chemical diversity and potential application in gas storage, molecular separation and heterogeneous catalysis. The strategies for synthesizing photoactive frameworks are still under development. Our goal is to successfull

In this paper I study a model for credit risk in a portfolio of sovereign bonds, based on (van der Hoorn, 2009). The model is based on historical credit rating changes and the joint distribution of the losses for dier- ent bonds is modeled with an assumption of an underlying multivariate Gaussian variable. Dierent risk measures for the portfolio are calculated using Monte Carlo simulations and the
