Detta examensarbete syftar till att utveckla en enkel mätmetod av flyktiga organiska föreningar (VOC) som frigörs från bitumen, en kritisk komponent i tillverkning av asfalt. Med tanke på att bitumen är en råoljeprodukt, särskilt vid uppvärmningen, är det viktigt att noggrant övervaka och kontrollera dess emissioner under bearbetning för att säkerställa en hållbar resurshantering. I detta arbete This thesis aims to develop and improve a simple measurement method for volatile organic compounds (VOC) released from bitumen, a critical component in asphalt manufacturing. Given that bitumen is a petroleum product, especially during heating, it is crucial to meticulously monitor and control its emissions during processing to ensure sustainable resource management. This work presents a straight

Kombucha contains a plethora of compounds that contribute to its health benefits apart from its probiotic effects. This project was conducted to determine the total polyphenolic content (TPC) and total antioxidant content (TAC) of kombucha prepared with black tea, oolong tea, and green tea as a function of fermentation time (day 0 to day 18). Amongst all the kombucha samples, green tea kombucha on

This thesis explores the connection between gender identity and experiences of elections within the Italian sociopolitical context, focusing on the realities of trans* and gender non-conforming individuals. It investigates the implications of electoral procedures that reinforce essentialist, binary gender norms, particularly building them on separating Italian voters into male and female lines, as

This research is part of a larger project exploring the use of surface modified microcarriers, specifically polystyrene and PDMS, as a chromatographic medium to enable high resolution liquid state NMR-analysis of biological samples such as blood and plasma. The purpose of the microcarriers is to bind proteins and lipids, which distorts the NMR-spectrum, hence enabling identification of metabolites

Ongoing fermentation in kefir can lead to packaging issues like bulging packages and changes in sensory properties, potentially affecting consumer acceptance. Effective packaging is essential to address these problems and maintain product quality throughout its shelf life. This study aims to investigate the interaction between various packaging types and kefir products over their shelf life. It ex

Disks around single white dwarfs have been observed as infrared excesses since 1987. Over time, these excesses have shown variability, leading to the conclusion that these debris disks undergo changes. However, the infrared excess should not be the only detectable signature from these disks. They are also expected to reflect visible light, a phenomenon yet to be studied for white dwarf debris disk

In this thesis, the eigenenergies and eigenstates of the quantum Rabi model, a foundational model of light-matter interaction, are investigated. The focus lies on three different regimes characterized by the coupling strength: the weak-strong, ultrastrong, and deep-strong regime. To study the quantum Rabi model in these regimes, approximations including the rotating-wave approximation, the Scrieff

En tur till närmsta trädgårdsbutik. Jorden, gödslet och fröna ligger stabilt i kundvagnen. Drömmen om att odla din egen mat lever starkt. Kanske kan du till och med bli självförsörjande en dag. Närodlat, hälsosamt, rogivande; att odla sin mat själv kan ge mening till livet. Längtan efter att få ta den första tuggan. Har tanken slagit dig ännu; är den egenodlade maten säker att äta? Majoriteten av A regular consumption of food contaminated with heavy metals can pose a threat to the general health of the human population. The contents of these toxic metals in crops depend on several different factors including the acidity of the soil as well as the addition of contaminated fertilizer. In this study, health risk assessments for broad beans (Vicia faba) were made for six different growing cond

Sammanfattning Förtroendet för samhällsinstitutioner har genom historien varit avgörande för deras bestående. I utvecklade samhällen som Sverige behöver medborgarna förlita sig på att lagföringen görs korrekt. Förtroendet är i sin tur avgörande för att människor rättar sig efter domar och beslut. Tydlig kommunikation är vidare ett krav för att tilliten till domstolarna ska kunna byggas samt stärkaSummary The trust in social institutions has throughout history been crucial for their continuance. In developed societies like Sweden, the citizens have to trust that prosecutions are processed correctly. The confidence in these proceedings is vital for the compliance of decisions and judgements. Clear communication is a requirement for trust to be built and strengthened. Texts produced and publi

Stormfloder orsakar förhöjda vattennivåer och kraftiga vågor. Det kan leda till omfattande erosion och översvämning längs med den drabbade kusten, vilket kan utgöra ett verkligt hot mot kustnära samhällen. Som en del av riskbedömningen kan det vara intressant att studera överspolningssediment (washover) som deponerats under tidigare stormfloder. Men för att kunna särskilja dessa ur det sedimentäraStorm surges cause elevated water levels and strong waves. This can lead to severe erosion and flooding along the affected coast, which can pose a real threat to coastal communities. As part of the risk assessment, it may be interesting to study washover sediments deposited during previous storm surges. However, in order to distinguish these in the sedimentary archive, their characteristics must b

The intricate nature of water distribution networks and the challenge of managing seasonal water consumption variation pose a significant hurdle for water utilities striving for low energy consumption. The performance of pumps, which are the backbone of these networks, directly influences the energy required for distributing drinking water. Such conditions are modelled using MIKE+ for the water di

The rise of Iron Age central places has become a complex debate. Traditionally, central places have been described as places of power, serving multiple public functions – political, economical, and religious, to name a few – at a regional or supra-regional level. Few researchers have further nuanced or challenged the concept, and therefore, the complexities of central places have often been undere

This bachelor’s thesis explores the effectiveness of cybersecurity training programs within a Swedish financial institution, utilizing the Theory of Planned Behavior (TPB) as the guiding theoretical framework. The research employed a qualitative approach, conducting an online survey with 28 bank employees to gain in-depth insights into their experiences and perceptions. The findings reveal several

Media holds an irreplaceable role in liberal Western democracies as it assumes core democratic functions such as disseminating information, representing public interests and taking on the role of a watchdog. In relation to the rise of populist radical right parties, research has revealed that media holds a crucial role. Hence, within the context of the rise of the populist radical right party Swed

I samband med 1960-talets ekonomiska och industriella utveckling importerade Sverige mycket arbetskraft vilket ledde till en omfattande bostadsbrist. Därför behövde det byggas många hus i hög takt vilket innebar att en hel del nya metoder och oprövade material användes. En del av dessa lösningar har visat sig vara olämpliga och tillsammans med den då bristande fuktkunskapen har dessa hus idag en hIn connection with the economic and industrial development of the 1960s, Sweden imported a lot of labor which led to a significant housing shortage. As a result, many houses were built at a rapid pace, leading to the use of a lot of new methods and untested materials. Some of these solutions have proven to be unsuitable, and coupled with the lack of moisture knowledge at the time, these houses hav
