This thesis focuses on how changing the combustion chamber geometry in a small two-stroke engine can improve performance. The engine used for this thesis is a Husqvarna AB chainsaw engine with Schn¨urle porting and air-leading stratified scavenging. Four different combustion chambers were subjected to CFD simulations, and from them two were selected for engine testing. In total, five combustion ch
In recent years, China has carried out large-scale poverty alleviation and relocation policies, helping many people living in remote mountain areas move into newly built urban resettlement communities near cities. These policies greatly improved living conditions, but at the same time, many daily rhythms and living habits that once existed in villages have been strongly affected by standardized ur
Food loss and waste (FLW) is an urgent global challenge. France pioneered in implementing a binding legal framework that incentivises supermarkets to donate their surplus to charities. In this thesis, I combine responsibilisation theory and a feminist political ecology lens to investigate previously overshadowed aspects of this law. I demonstrate that the responsibility for food waste (FW) managem
This thesis explores the furry fandom and, more specifically, fursona construction and realization of the furries’ “fursona”. The furry fandom is a community of people with a “fan-like interest” in media centering anthropomorphic animals, and members of the fandom are called furries. Drawing on the individual experiences of furries through nine semi-structured interviews, the study aims to give an
This study aimed to examine which organizational demands social workers experience in their work with women exposed to intimate partner violence and how these demands influence their professional discretion. The study was conducted as a quantitative survey targeting social workers in Sweden working with intimate partner violence. A total of 58 responses were collected. The results show that high w
This research has explored the role actors from various scales have in the production of Research, Innovation and Smart Specialisation Strategies (RIS3) in the Eastern and Southern Netherlands through its multi-level governance framework. This could be worrying, as the influence from higher-scale actors could weaken RIS3’s ability to create place-based programmes. In order to gain an understanding
A longstanding debate in constitutional theory concerns the legitimacy of constitutional review and the scope of judicial interpretation. The core of the conflict is the conceptualization of the separation of powers and the related distinction of law and politics. Strategic litigation stresses this existing normative tension, because it brings issues to court with an agenda that goes beyond the in
As Swedish migration laws become increasingly exclusionary, there exists integration activities which resist this rhetoric. This thesis looks at the activities carried out by Lunds Kommun social workers, and the organisation Interkultur i Lund. Through my own work as an intern with Lunds Kommun, in the Barn i Start team, I carried out 20 weeks of participant observation, and experienced fun, play,
High-pressure homogenisers (HPHs) are used for a variety of food products to create emul-sions. It is interesting both from a sustainable and economical perspective to make HPHs more energy efficient due to their high energy demand and low efficiency. Previous research has shown that drop deformation is affected by the whole HPH valve geometry, including the inlet chamber, and it is hypothesised t
I denna studie fokuserar vi på ett särskilt pedagogiskt förhållningsätt bland jazzpedagoger, vilket vi båda återkommande behövt förhålla oss till under våra jazzstudier. Detta förhållningsätt kännetecknas av stort elevinflytande och fokus på att studenten utvecklar autonomi. På grund av genrens historiska band med USA samt att ovannämnda förhållningssätt står i kontrast till amerikanska jazzpedagoIn this study, we put focus on a particular pedagogic approach among jazz teachers that we’ve encountered during our studies in jazz. This approach is characterized by giving students space to form their own studies and to develop the student’s independence through self-learning. Because of the historical bond that jazz shares with USA and because of the strong contrast within the character of the
Audiovisual synchronization significantly impacts the viewing experience in streaming environments, yet research on latency sensitivity toward spatial audio in Virtual Reality (VR) remains limited. This study conducted an audiovisual synchronization experiment in a virtual opera house, where 18 participants performed multisensory integration tasks using the Meta Quest Pro. The results indicated a
Nuclear power plays a key role in the ongoing energy transition, where efficient performance monitoring is essential to ensure reliable power production. In this thesis, performance monitoring at the Ringhals nuclear power plant is evaluated with the aim of enhancing the understanding of the steam turbine cycle performance, particularly focusing on the condenser and steam turbine. A comprehensive
Övergången till mer hållbara livsmedelssystem och växtbaserade proteinkällor har blivit allt viktigare för att minska livsmedelssystemets klimatpåverkan. Rapsfrökaka är en restprodukt från oljeextraktion med potential att användas som råvara för proteinutvinning och vidare tillämpning i växtbaserade livsmedel tack vare dess balanserade komposition av aminosyror. På grund av bitter smak och högt inThe transition to more sustainable food systems and plant-based protein sources has become increasingly important in reducing the climate impact of the food system. Rapeseed press cake is a by-product of oil extraction that has the potential to be used as a raw material for protein extraction and further use in plant-based foods, thanks to its balanced amino acid profile. Due to its bitter taste a
The aim of this thesis is to investigate whether quantum interference between indistinguishable hadronization histories, that is, different ways the string can break while resulting in the same final state, can lead to observable effects in the momentum distributions of particles produced in string fragmentation. In the standard picture, hadronization is treated as a probabilistic process in which
The research examines the application of Article 101(1) TFEU to concerted practices involving indirect information exchanges facilitated through a common intermediary. It evaluates whether the existing framework governing Hub-and-Spoke arrangements are capable of addressing algorithmic collusion where pricing algorithms replace the intermediary. Through a doctrinal analysis of Article 101(1), rele
Wind-assisted ship propulsion has gained increasing attention as a means of reducing fuel consumption and emissions in the maritime sector. This thesis studies the aerodynamic performance of an adjustable rigid wingsail designed to provide auxiliary thrust for ships. The wingsail consists of a NACA 0018-based main airfoil with a movable flap, where the flap deflection, hinge position, and gap betw
Byggbranschen står för en betydande del av vår klimatpåverkan, både globalt och i Sverige, där en stor andel av samhällets utsläpp av växthusgaser och avfall som genereras kan kopplas till sektorn. I Sverige är den största andelen av avfallet från byggbranschen jord- och schaktmassor och hanteringen av massor inom anläggningsprojekt står för ungefär 16% av de totala utsläppen i projektet.

Bakgrund: Användandet av aktivitetsbaserade interventioner har visats ha positiva effekter för rehabilitering samt för arbetsterapeuters roll och yrkesidentitet. Samtidigt finns det utmaningar för tillämpningen av aktivitetsbaserade interventioner i sjukhusmiljö som kan begränsa användningen. Syfte: Syftet var att undersöka användningen av aktivitetsbaserade interventioner inom regional hälso- ochBackground: The use of occupation-based interventions has been shown to have positive effects on rehabilitation and occupational therapists' role and professional identity. At the same time, there are challenges applying occupation-based interventions in a hospital environment. Aim: The aim was to investigate the use of occupation-based interventions in regional healthcare. Method: Cross-secti
Women’s access to essential medicines is restricted by intersecting barriers such as economic dependence, reproductive health stigma, information gaps, and pharmaceutical R&D priorities that overlook their needs. Access to medicines is simultaneously shaped by international intellectual property law, particularly patent protection under the TRIPS Agreement, which has been criticised for restri
Background: The global plant-based food shift puts high pressure on manufacturing capacity at facilities like Oatly's Landskrona site. This environment faces high combinatorial complexity due to growing product variety and sequence-dependent cleaning requirements. Relying on manual, experience-based planning to navigate these rules limits throughput and introduces organisational risk. Purpose
