Diet-related diseases kill millions of people every year and pose significant costs to the economy and society. In Sweden, this is an increasingly prevalent phenomenon. However, a healthy diet can prevent this. This thesis investigates what costs and benefits there are to adopting healthy eating habits and how these effects impact the Swedish economy. This thesis finds that the costs and benefits

In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. Anionic surfactants can unfold proteins and form complexes in equilibrium manner. The complex structu

The project aimed to analyse by liquid chromatography coupled to high resolution mass spectrometry (LC-MS/HRMS) the extracellular proteins synthesized by Rhodothermus marinus strains DSM 4252T and DSM 16675 growing in medium containing different carbon sources. That is critical to find valuable enzymes for industrial uses in biomass conversion into value-added chemicals. Cells were grown in medium

Fastigheter anses på grund av dess unika egenskaper att vara en av de bästa skattebaserna, och i takt med globaliseringens acceleration blir betydelsen av skatteintäkter från denna skattebas allt större. I Sverige har skatteuttaget från denna skattebas trendvis minskat med åren, något som sticker ut på ett internationell plan. Syftet med rapporten är att jämföra olika fastighetsbeskattningsmodellReal estate is regarded as one of the best tax bases due to its unique characteristics. As globalization accelerates, the importance of this tax base is increasing. In Sweden, the tax revenue from real estate has trended downward over the years, something that stands out internationally. The purpose of this report is to compare different property taxation models for detached single-unit propertie

When a stroke patient visits a physiotherapist for rehabilitation, various tests are often conducted. The results from these tests need to be stored somewhere, and currently, there is no efficient method for doing so. The best available option is an Excel spreadsheet that calculates the results, followed by the physiotherapist having to save the data in another way. This process is time-consuming,

Thesis Purpose: This study examines how parasocial relationships between music artists and fans foster a plethora of different consumer attitudinal outcomes, with the purpose to provide clarity through the shaping of distinct consumer archetypes, while offering in this way practical insights for marketers and industry professionals. The context of K-pop is used to delve deeper into the understandi

Since 2019, Icelanders can self-determine their legal gender. A third “neutral” option was also added. However, formulations in the Act allow only one self-determined change (Act on Gender Autonomy, 2019). Research on self-determination of legal gender has shown how acts can have limited effects since legal change is insufficient in addressing injustice. The separation of medical and legal concern

Att mark tas i anspråk för allmänna ändamål såsom kraftledningar är nödvändigt för att samhället ska fungera. Företags- och miljöskada, två skador som uppkommer för fastighetsägare i samband med markåtkomst. För att bibehålla ett äganderättsligt skydd innebär båda skadorna att fastighetsägaren har rätt till kompensation för intrånget om vissa kriterier uppfylls. Företagsskada regleras i ExpropriatEnvironmental- and enterprise damage are two freehold compensations related to land acquisition. They are regulated in The Environmental Code and Expropriation Act. Enterprise damage implicates damages created by the activity that occurs on the expropriated property, such as noise, view disturbance, psychic immissions etc. Environmental damage implicates the same damage however in question of prop

In the following thesis, the development of the biofuels sector in the United States will be analysed using environmental economics. Around year 2005, there was a significant increase in the production of liquid biofuels. Hence, the thesis aims to explore the reasons behind the increase. Acts of government have been analysed while enlisting the help of summaries and overviews accessed through v

The dissertation explores the refugees and EU securitization processes pursued by Hungary and Poland during the period of refugees’ crisis. The securitization theory is used along with CDA and topos tool to analyse the politicians’ speeches and statements, the joint reports of the two countries, besides Orbán’s national consultations. Where a clear security language in all of these sources that li

The agri-food system has driven economic development and supported the growing population, but it has also significantly contributed to greenhouse gas emissions. Moreover, the system is vulnerable and faces challenges that hinder innovation and sustainability. Transitioning from a linear to a circular economy model in the food system can effectively restore biodiversity, combat climate change, and

En förhöjd temperatur på jorden på grund av solens utveckling kan leda till förödande konsekvenser. Allteftersom solen åldras ökar den nämligen i ljusstyrka – vilket gör att vår planet nås av en större mängd ljus. Därmed värms planeten upp och detta kan på sikt leda till en förstärkt växthuseffekt och en skenande temperatur. Även om temperaturändringen inte är märkbar i nuläget kommer den om ungefThe stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. Such structures, if they exist, are potentially detectable with current or near-future tech

During the last few years several violent school attacks have taken place in Sweden, leading to a debate in both the media and in politics concerning school security. There is pressure from the public to “make schools safer”, with some steps being taken on a legislative level. This thesis aims to understand how security is represented as a problem in the Swedish Education Act’s preparatory work, a

Där uppe finns de. Stjärnorna som om natten pryder himlavalvet är fängslande i deras mängd och mångfald. Om du befinner dig långt bort från städernas ljus så kan du se nattens sanna skönhet, och om du tittar riktigt noga kan du börja uppskatta att alla stjärnor inte är likformiga vita prickar. Vissa är ljusstarkare, vissa är ljussvagare. Vissa är rödare än andra och vissa ser blåare ut. För astronThe observed upper limit of the luminosity of red supergiants, often called the Humphreys-Davidson limit, has recently been shown to be independent of metallicity and to not be explainable by single star evolution – findings that both contradict established ideas of the origins of the limit. It is now known that the vast majority of stars with sufficient mass to possibly evolve into red supergiant

Under de senaste åren har kontorsmarknaden varit under förändring, framför allt som en effekt av Covid-19-pandemin och teknisk innovation. Detta har påverkat hur kontorslokaler används och inneburit ett ökat utbud av fastighetsprodukter. Ett av de beslut som organisationer behöver ta är om de ska äga eller hyra sina lokaler, vilket är ett beslut styrt av flera parametrar. Det rätta beslutet för enIn recent years, the office market has been changing, mainly due to the Covid-19 pandemic and technological innovation. This has impacted how office space is used and has led to an increase in the range of available real estate products. One of the decisions organizations need to make is whether to own or lease their space, which is a decision driven by several parameters. The right decision for a

Att öka tillgängligheten av läkemedel är en viktig del i att minska lidandet för miljontals personer världen över. Om detta kan göras genom att korta utvecklingsprocessen för generiska läkemedel undersöks i detta examensarbete. På apoteket är en vanlig fråga om man vill ha ett liknande läkemedel till det man egentligen hade tänkt köpa, ofta till ett billigare pris. Läkemedelsutveckling är en lånThe development of generic pharmaceuticals includes extensive data on equivalence with the reference listed drug is required by the European medicinal agency (EMA) and the North American equivalent. Equivalence must be proven for rheology, microstructure, and performance. This is a costly and time-consuming process. To reduce the costs, it is of interest to investigate if the release profile (perf
