The bearing capacity of road E22 from Hurva to Linderöd is analyzed using data from Falling Weight Deflectometer, FWD. A new method called Traffic Speed Deflectometer, TSD, is analyzed and compared to data from FWD to determine the application range of the new method. In addition to these analyzes, various bearing capacity dimensions are explained and used for both methods. From the FWD data a bac
The purpose of this paper was to research how environmental concerns and sustainable thinking could be integrated into the design process of Electrolux, a Swedish home appliance manufacturer. The research will hopefully help the Electrolux industrial design department improve in the area and prove as a good case study for other companies or academic institutions. Electrolux conducts much research
This master’s thesis report describes the development of a new system for control and monitoring of a helium liquefaction plant which has been carried out at Kryolab, Lund University. At the plant, helium gas is purified and then cooled in several steps until it condensates. The plant is very similar to the ones constructed today, but Kryolab wished to replace the outdated control system. The new
Att göra datorsimuleringar av komplexa kemiskt reaktiva system, såsom gasbrännare och motorer, kan vara tidskrävande. Reaktornätverk är en simuleringsmetod där beräkning av detaljerade kemiska reaktioner separeras från beräkning av flöde vilket ger en kortare beräkningstid. En metod för att automatiskt konstruera sådana nätverk har utvecklats och testats på en brännare för gasturbiner och på en öpThe main goal of this thesis was the development and application of a method to construct reactor networks based on pre-calculated flow fields for combustion systems. Computational fluid dynamics (CFD) was used to calculate flow fields for the Sandia piloted jet flame D and a Siemens SGT-800 gas turbine burner rig. Two different combustion models were tested in the computational fluid dynamics cal
Det finns ett samhällsintresse att verksamheter i offentlig regi drivs så kostnadseffektivt som möjligt. När verksamheten har ett minimikrav på bemanning som krävs för att driva verksamheten, kan arbetsuppgifter inte överföras på andra anställda vid någons frånvaro. Den frånvarande måste ersättas. Detta innebär att många verksamheter drivs med viss ”övertalighet”. Syftet med denna fallstudie var aThere is a public interest that activities operated by the public sector are run as cost effectively as possible. When an organization has a minimum requirement of staffing required to run its activity, work cannot just be transferred to other employees at someone's absence. The absentee must be replaced. This means that many organizations are run with some "redundancy". The purpose
Vegetation on land is globally taking up about 30% of the CO2 that is emitted by human activities (oceans take up 30%, while 40% remains in the atmosphere). This ability to store carbon in the vegetation and in the soil is very important to mitigate the climate changes, but all land based ecosystems are not carbon sinks. Ecosystems that are losing carbon needs to be further investigated, so we can
This investigation concerns written output produced by Swedish learners of English as a second language (L2) and French as a third language (L3). The analysed texts were rated according to the Common European Framework of Reference for Languages (CEFR), which is a widespread and language-independent document commonly used to assess communicative competence based on six main proficiency levels (A1,
Syftet med denna studie var att beskriva och analysera hur arbetet med ensamkommande barn bedrivs. Forskningsfrågorna fokuserade på hur integrationshandledare arbetar för att tillgodose barnens behov, hur de arbetar med integrationsprocessen och slutligen vilka utmaningar de möter i arbetet. En kvalitativ ansats valdes med semi-strukturerade intervjuer med fem integrationshandledare som primärdatThe purpose of this study was to describe and analyse how the work with asylum-seeking children without parents or guardians is conducted. The underlying questions focused on how the integrations handlers work to fulfil the needs of the children, how they work regarding the children’s integration processes, and finally what challenges they encounter in their work. A qualitative approach was chose
Ecological rehabilitation projects - as a form of reforestation interventions - are increasing worldwide and present an opportunity for climate change mitigation and supporting local livelihoods. Implemented in post-conflict situations, they are increasingly promoted as solutions for peace. Aiming at understanding their contributions to sustainability and peacebuilding, I examine proposed rehabili
Death and grief in fairytales. An exploratory literature study The aim of this study was to examine how death and grief is portrayed in fariy tales and how we can understand these stories from a therapeutic purpose. Our main questions were: What general norms are conveyed in the fairytales? What norms on grief and death are produced in these stories? What would these stories convey if they were t
Following changes on a European level, there are plans to also in Sweden reduce the characteristic value of shear strength of glued-laminated timber. In Sweden, a decrease of approximately 30% from a characteristic value of 4.0 MPa (for glulam L40) to 2.5 or 3.0 MPa is planned. This would mean that wood would lose competitiveness against other construction materials such as steel and concrete. T
Möjligheten att visualisera olika sjukdomstillstånd med hjälp av bilder har inom sjukvården blivit mer och mer populärt. Nuklearmedicinska bilder framställs genom att en liten mängd av ett radioaktivt ämne injiceras i patienten och sedan detekteras med hjälp av en gammakamera. Genom att utnyttja olika upptagsmekanismer kan funktionen av ett område eller ett specifikt organ i kroppen undersökas. BlThe purpose of this work is to assess the activity level needed to achieve satisfactory diagnostic information in regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) by introducing a new evaluation method to be used for and hopefully facilitate optimization studies in nuclear medicine in the future. The purpose is further to perform a visual grading study and inves
This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extractio
Frågan om kriminaliseringen av köp av sexuella tjänster är med jämna mellanrum är uppe för diskussion och är därför ett ständigt aktuellt ämne. Efter 2018 års sexualbrottsreform går gränsen för ansvar för våldtäkt vid bristande frivillighet. Reformen innebar således en ökad möjlighet att döma för våldtäkt generellt, och därför även vid sexköp. Denna uppsats syftar därför till att utreda hur de tvåThe criminalization of purchasing of sex is always up for debate and therefore it is constantly a relevant subject. Since the 2018th sexual crime reform, the limit for criminal liability for rape has been the lack of voluntariness. The reform thus meant an extended possibility to convict for rape in general as well as in relation to the purchase of sex. Therefore, the aim of this essay is to inves
Progressing urbanisation puts strong pressure on existing infrastructure, forcing new projects to provide for society’s increased demand. Owing to modern state-of-the-art knowledge and imposed regulations, publicly driven initiatives are mandatory to use Building Information Modelling (BIM) and Geographical Information Systems (GIS) technologies for project realisation. The thesis examines High Sp
På senare tid har en särskild typ av företag, vars affärsverksamhet går ut på att hyra bostadslägenheter för att vidareupplåta dem till företag som behöver personalbostäder, vuxit fram på hyresmarknaden i Sverige. Detta fenomen är vanligast i storstadsregionerna, företagen brukar kallas för mellanhandsföretag och bostäderna som hyrs ut för företagsbostäder. En av reglerna som aktualiseras vid dennIn recent years, a new category of business has emerged within the Swedish rental housing market, operating by leasing residential flats and subsequently subletting them to companies in need of staff accommodation. This phenomenon is most prevalent in metropolitan areas. Such businesses are usually referred to as intermediary companies, and the flats as corporate apartments. One of the legal provi
Plant macrofossil and pollen records from the partially varved sediments of Lake Odensjön in southernmost Sweden provide detailed information on local forest development and land-use history within Söderåsen National Park during the past 600 years. A relatively dense forest dominated by Fagus (European beech) covered the steep talus-dominated slopes surrounding the lake during at least a century p
