Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions. The problem is the ignitability at low load and idle operating conditions.In a previous study it was shown that it is poss

Amphibians are globally among the most endangered taxonomic groups of vertebrates. This is partly due to the chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis, that have led to eradication of more than 90 species of amphibians worldwide. The spadefoot toad (Pelobates fuscus) is one of the Swedish red listed species (VU) that are at risk of being affecte

The importance of sustainable and effective energy usage is rapidly growing. SWEP International AB leads the manufacturing of brazed plate heat exchangers that offer effective heating and cooling applications used in various systems and industries. Stud bolts are manually welded onto the heat exchanger surface in their manufacturing process. A project to fully automate this process using an indust

We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large- scale assessment in 14 countries that include individual-level information on student achievement and country-level measures of teacher subject knowledge and didactic skills in reading and math.

Postgraduate course IntroductionThe aim of the course is to introduce the PhD students to the Monte Carlo-methods for simulation of the interaction of photons and charged particles, which mainly apply to applications in image generation and dosimetry. The theory behind interactions of photon and charged particles (electrons and protons) will be examined in detail and with this, different type of m

This paper concerns Sec. 23 the Codetermination at Work Act, and the necessary conditions for when a collective agreement is considered to exist and the relevance of contract of law when it is applied. The idea is to point at areas within contract of law that becomes particularly important at the application. The paper begins with a chapter that, in short terms, describes the background within co

The objective of this thesis is to be used by rescue services in order to gain a deeper understanding regarding drowning and water rescue operations. By compiling research data from previous studies, statistics and opinions from rescue personal as well as experts in the field a basis is provided on which further queries within developing water rescue can be looked into for rescue services. Rescue

To fully decarbonise the energy system, electrification is needed as one of the most important strategies for reducing carbon dioxide emissions in Sweden and Europe. The deployment of renewable energy resources plays a central role in electrification and will continue to increase. In January 2024, Svenska Kraftnät published a long-term market analysis with four future scenarios regarding the devel

In recent years, LARP events (live action role playing) have become more popular in Sweden and permanent buildings have been built in a number of LARP event areas. But despite that a desire for good event management may exist, the knowledge may be lacking. This master thesis aims to study the risks and dependencies on LARP events with the goal to answer the question: “What should be included in sa

Naturen är på många sätt avgörande för människans fortlevnad. På grund av mänsklig aktivitet och exploatering riskerar unika arter och naturtyper att gå förlorade. Skogen är en av de miljöer som är hårt drabbad. Intensivt skogsbruk har lett till en kraftig minskning i mängden skog världen över med förlust av biologisk mångfald som följd. En viktig skogslevande grupp som drabbas av habitatminskningNature is in many ways crucial for human survival. However, due to human activity and exploitation, unique species and habitats are at risk of extinction. The forest is one habitat that has been deeply afflicted. A massive loss of forests worldwide due to intense forestry has led to a defeat of biodiversity. Saproxylic beetles is one group of forest dwellers that has been affected by habitat loss.

North America, Western Europe, China, and India are today the greatest emitters of carbon dioxide. This research aims to compare the development of North America and Western Europe with the Chinese and Indian ones. It is a comparison of the key factors that affects the emissions of CO2 from fossil fuels. The key factors are the ones proposed by the Kaya identity, a particular type of decomposition

Popular Abstract in English Every year globally, an estimated 1.7 million women are diagnosed with breast cancer, while over half a million are killed by this disease. The principal cause of death is metastasis, which is the spreading of the cancer cells from the breast to other vital organs like the brain, liver or lungs, resulting in organ failure and subsequently death. Even though the past decMetastasis is a complex process that remains a major challenge in the clinical management of cancer, because most cancer-related deaths are attributed to disseminated disease rather than the primary tumor. Despite the significant advances in the prediction of prognosis, and therapeutic management of primary breast cancers, coupled with the substantial improvement in our understanding of the molecu

Markov Regime-Switching GARCH (MRS-GARCH) models have been gaining popularity due to their ability to account for shifts volatility regimes that tend to characterize returns series. Previous empirical studies have shown that this capacity to capture the volatility dynamics leads to a superior forecasting power of the MRS models. We investigate the performance of these models in quantifying and man
