In this work, a two-dimensional computational fluid dynamics study is reported of an n-heptane combustion event and the associated soot formation process in a constant volume combustion chamber. The key interest here is to evaluate the sensitivity of the chemical kinetics and submodels of a semi-empirical soot model in predicting the associated events. Numerical computation is performed using an o

Industrial Symbiosis (IS) is a tool that may facilitate coordination of the factors necessary to improve resource use efficiency in regional levels. This thesis studies the potential of developing an IS network in rural Portugal, that could support the competitiveness of the local companies, whilst also improving their own and the regions environmental profile. The research is based on a hybrid o

We evaluated the influence of the brown rot fungus Hygrophoropsis aurantiaca on P solubility in the humus layer of a podzolic forest soil. This fungus is known to exude large amounts of oxalic acid that may stimulate weathering of minerals and increase dissolution of humus, which in turn may increase P availability in the soil surrounding the fungus. Humus was inoculated using small wooden pieces

The application of detailed chemistry to the computational fluid dynamics simulation of combustion process in diesel engines has many potentials, including the possibility to predict auto-ignition, diffusion flame structure, stabilisation and soot formation in a wide range of operating conditions, also taking into account the effects of different fuel types. Among the approaches that were proposed

Background/Aims: Activation of trypsinogen to trypsin is a crucial step in the development of acute pancreatitis. The cause of this activation is not known although suggested explanations include autoactivation, cathepsin B-mediated activation and activation by mast cell tryptase. The aim of this study was to investigate cathepsin B and tryptase activation of pancreatic zymogens. Methods: Trypsino

Bakgrund: Fallolyckor har ökat den senaste tiden och orsakar stora kostnader för samhället samt lidande för den drabbade. Det är viktigt att sätta in insatser i fallprevention för att motverka detta. Socialstyrelsen har samordnat en kampanj på uppdrag från regeringskansliet för dessa insatser. I dagsläget används instrument med mått som är ospecifika samt svåra att kvantifiera för att utvärdera fa

Denna uppsats utreder hur finansiella produkter klassificeras i inkomstslaget kapital, och vilka skatterättsliga skillnader som finns mellan de olika kategorierna i inkomstslaget. Utifrån praxis och inkomstskattelagens systematik redogörs för hur en avyttring av kryptovalutan Bitcoin ska klassificeras och beskattas. Gällande rätt analyseras sedan mot bakgrund av principen om likformighet och skattThis paper examines how financial products are classified within the capital gains bracket and which tax differences follow from such classification. Based on practice and the methodology of the Income tax act, the paper describes how a divestment of the cryptocurrency Bitcoin should be classified and taxed. The result is thereafter analyzed from the perspective of the principle of uniformity and

This thesis concentrates on one of the indirect Dark Matter (DM) detection methods, namely through observations of Very High Energy (VHE) $\gamma$-ray signals from DM annihilation (or decay) in cosmic sources using the Imaging Atmospheric Cherenkov Technique (IACT). We discuss the particle physics and astrophysical aspects of those observations and perform several calculations which lead to an est

OBJECTIVE: Screening for abdominal aortic aneurysm (AAA) using ultrasound in men reduces aneurysm-related mortality. Ambulatory screening and surveillance procedures facilitated by point-of-care ultrasound (POCUS) may improve adherence to screening programs. This proof-of-concept study evaluated whether infrarenal aortic diameter (IAD) can be accurately and interchangeably measured using handheld

The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th

The lack of circular economy is a global problem; cur- rently, we use more resources than what is sustainable for our planet. One material that is highly critical to take action towards sustaining is the raw material of natural rubber. By reusing the rubber that currently is used in ti- res for other products, we can create a stronger circular economy for the material and thus use less new res

Internetanvändning och sociala medier har under de senaste åren exploderat, var på reklamvärlden har stått inför en förändring. Sociala medier har blivit en plats full av tips och inspiration, men också en arbetsplats för influerare som gör reklam för diverse produkter och tjänster. Det är av betydelse att en konsument kan se skillnaden mellan ett tips och reklam för att undvika att känna sig luraInternet usage and social media have exploded in recent years, which has brought about a change to advertising. Social media has become a place full of recommendations and inspiration, but also a workplace for influencers who promote various products and services. Consumers are having a hard time to distinguish between a tip and an advertisement which can lead to a feeling of being deceived. This

Idrottande ungdomar, i åldern 12-20 år, har ett specialbehov vad gäller kosten i jämförelse med andra individer. Då ungdomarna fortfarande växer och utvecklas är en sund kosthållning ytterst angeläget för upprätthållande av en normal kroppslig utveckling. Dessutom ställs i och med idrottandet högre krav på näringsintaget eftersom mer energi- och näringsämnen samt vätska förbrukas på grund av den fYoung athletes, between 12-20 years, have special dietary needs in comparison to other individuals. Since these individuals are still growing and maturing, a healthy diet is of utmost importance for the maintenance of a normal physical development. Moreover; due to physical activity the requirements of energy, nutrients and fluids are higher for young athletes. In order to achieve optimal physical

Avancerade 3D skrivare är en etablerad teknologi och används inom många olika områden. Nu finns det möjligheter att 3D printa hus, proteser och även viss mat kan 3D printas. Detta visar att denna typ av 3D teknologi har en oerhörd bredd och potential. På senare tid har enklare 3D skrivare utvecklats för kommersiellt bruk. Detta har gjort att teknologin blivit mer lättillgänglig för allmänheten ochIntroduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications. This master thesis will inves- tigate if there is a possibility to use a FDM 3D printer to construct an optically stimu

Background: The solute carrier family 30 member 8 gene (SLC30A8) encodes a zinc transporter in the pancreatic beta cells and the major C-allele of a missense variant (rs13266634; C/T; R325W) in SLC30A8 is associated with an increased risk of type 2 diabetes (T2D). We hypothesized that the association between zinc intake and T2D may be modified by the SLC30A8 genotype. Results: We carried out a pro
