Narkotikabruk leder ofta till skador på den fysiska och psykiska hälsan. Konsekvenserna av att bruka narkotika är bland annat försämrad impulskontroll, leversjukdomar, psykoser och ökad risk att dö i förtid. Därtill kan det råda svårigheter att sluta nyttja droger eftersom den missbrukande individen upplever abstinensbesvär. Varför en del människor börjar använda droger kan exempelvis vara att de
Swedish youth-centres are characterized by their vision of being a “meeting place for all”. To fulfil this vision, inclusion has become a relevant concept and tool for those working within these centres. This thesis is based on interviews with seven youth-workers and managers within youth-centres in a large Swedish municipality. The aim of the study is to investigate how youth-workers and managers
Reducing the environmental impact from packaging has become a highlight in both consumers and industrial interest. The paperboard from virgin fibres is commonly used in the folding carton packaging across various type of products, including health care products. It provides the premium perception to the product value yet less circulates the fibre economy. After the paperboard folding carton serves
In Sweden, what we eat accounts for about a third of the consumption-based greenhouse gas emissions, and there is strong evidence that the most effective way to reduce emissions is to switch to a more plant-based diet. A shift is currently underway in the Swedish food system; the market for plant-based products is showing an exponential growth, coupled with, for the first time since the 1950s, a d
The purpose of this study was to analyze how Retuna Återbruksgalleria by using Nudging, a behavioural theory, could operate as an environmental educator and attain a sustainable consumer which together could result in competitiveness on the market. Four different nudging tools was analyzed; simplification and framing of information, changes in the physical environment, the default option and the u
Due to the environmental impact of food waste and its implications on the economic performance of restaurants, the importance of reducing food waste has taken a central role in the management of restaurants. This paper examines the difficulties which arise in the restaurant industry in their efforts to reduce food waste. In addition the paper aims to answer the following questions: Is food waste p
The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t
The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o
Electric vehicles are becoming more common as one of many solutions to the increasingly serious problem of global warming. This comes with new safety challenges as batteries can upon malfunction or abuse enter thermal runaway and as a result catch fire or explode. The gases released from thermal runaway has been determined experimentally in published studies and have been shown to contain fluorina
Membrane proteins are important building blocks for several biochemical processes. The difficulty with membrane proteins is that they tend to be lowly expressed and can be difficult to manage. Therefore, membrane proteins are studied to a lesser extent than soluble proteins. Since membrane proteins are intrinsically hydrophobic, their purification and structural determination critically rely on so
Att skapa en cirkulär ekonomi med hållbara produkter är en nödvändighet för dagens samhälle, särskilt kopplat till de klimatutmaningarna som vi har idag från bland annat överkonsumtion och dålig hantering vid slutet av produkternas livslängd. Projektet fokuserar på att ta fram en produkt som gjorts på återvunna material och att utmana tidigare materialbegränsningar. Detta har gjorts med en betonin
Most electricity in Lebanon is produced by burning fossil fuels, which produces more than one half of domestic greenhouse gas emissions, and the state-owned electricity companies are unable to meet the demand. To increase the country’s generation capacity and simultaneously combat the effects of climate change, the government aims to produce 30% of its electricity from renewables by 2030. It is ho
MicroProteins are small, separately expressed parts of a larger protein and able to interfere with the full-length protein’s function. To enable modulation of hormone perception, microProteins were designed from the ethylene, cytokinin and gibberellin receptors. The protein isoforms designed to function as microProteins were overexpressed in Arabidopsis. Overexpression of a shortened gibberellin r
This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.
As Special Purpose Acquisition Companies (SPACs) are becoming the increasingly popular method of taking a company public, the lack of research on abnormal returns for this asset class since its introduction to the major exchanges validates a reason to expand the investigation. This thesis examines the potential abnormal returns found in different stages of recent SPACs lifecycle, dividing the SPAC
Järnvägsnätet i Sverige är över 15000 km långt. Järnvägsnätverket har en viktig roll i transporten av personer och gods i landet. Det är viktigt att övervaka och underhålla detta stora nätverk för att säkerställa god funktion och säkerhet. De senaste årtionden har utvecklingen av interferometriska syntetiska aperturradar (InSAR) och tidsserie tekniker lett till att forskare, geotekniker och ingenjThere is over 15,000 km of track in the Swedish railroad network. This network is vital for the transport of people and goods across the country. It is important that this network is monitored and maintained to ensure good function and safety. In recent decades the development of Interferometric Synthetic Aperture Radar (InSAR) and Time Series techniques has allowed researchers, geotechnicians and
A Jacobian free multigrid preconditioner for linear problems arising from Implicit Discontinuous Galerkin (DG) discretizations is implemented. The preconditioner is based on a multigrid method for a low order Finite volume (FV) discretization on a subcellgrid. L2-projections are introduced as a strategy to translate between the discretizations. Numerical tests on advection dominated linear advecti
Denna studie utgår från hypotesen att det finns mer läromedel av kvalitet som utgår från Lgr11, samt vilar på vetenskaplig grund och beprövad erfarenhet i svenskämnet än i musikämnet. Detta bekräftas under studiens gång. Bristen av läromedel gör att lärare ägnar mycket tid åt att skapa sitt eget material i musikämnet. Denna studie undersöker lärares tankar kring hur tillgången till läromedel i sveThis study starts with the hypothesis that there are more teaching aids that are designed in accord with Sweden’s latest curriculum Lgr11, based on science and proven experience in the subject Swedish than in music. This confirms later in the study. The lack of teaching aids means that teachers spend a lot of time on making teaching aids for the subject music. This study examines teachers’ thought
