Flygindustrin närmar sig ett vägval där sektorn kommer behöva bestämma sig för vilken typ av framtida energimöjligheter den ska använda sig av. En väg är att även fortsättningsvis använda sig konventionellt flygbränsle vilket med stor sannolikhet kommer leda till fortsatt ökande utsläpp globalt, och den andra vägen leder sektorn till hållbart flygbränsle, vätgasdrift och batteridrivna elektriska fThe aviation sector is approaching a crossroad where the industry will have to decide on what path to take going forward in terms of its’ energy needs. One path continues with the usage of non-renewable fuel resources such as jet fuel with the clear potential that global emissions will continue to rise, whereas the other path leads to newer technologies such as sustainable aviation fuels, hydrogen

The Hanson Larson evolution model assumes that wave height grows or decays from an initial condition towards an equilibrium wave height through a simple exponential growth. The model uses wind input data, fetch length and depth measurements. Using this input parameters, it both determines the wave height and period values, thus predicts wave climate. The model is developed using deep water conditi

Syftet med uppsatsen är att undersöka kravet på angelägna allmänna intressen i RF 2 kap. 15 § 1 st. och hur det förhåller sig till expropriationslagens och fastighetsbilningslagens bestämmelser om ingrepp i egendom. För att uppnå syftet används rättsdogmatisk metod. Kravet på angelägna allmänna intressen ska vara uppfyllt för det varje gång myndighetsbeslut eller lagstiftning genomför expropriatioThe purpose of this thesis is to examine the requirement for compelling public interests in chapter 2 paragraph 15 of the Swedish constitution and its relation to the provisions on property interference in the Expropriation Act as well as the Property Formation Act. To achieve the purpose, a legal dogmatic method is applied. The requirement for compelling public interests must be fulfilled wheneve

Lampetra planeri or Brook Lamprey is an aquatic fish-like species, characterized by its lack of jaws and long eel-like morphology. The species is usually found in small streams with gravel or sandy riverbeds and has seen a strong population decline during the last few decades. The primary goal of this thesis was to investigate if combined sewer overflows prevent the further spread of the Lampetra

Evacuation models can be reliably used if they are sufficiently validated for the application in question (e.g. Fire Safety Engineering). To be useful, an evacuation model should therefore be an accurate enough representation of the real-world behaviour of evacuees. The scope of this work was to determine how accurately the model crowd:it (making use of the Optimal Steps Model) provides a represen

To escape competition for food, South African dung beetles roll balls away from the dung pile of origin along straight-line paths. To keep their desired courses, the beetles rely on flexible integration of external orientation cues. This supports robust orientation even under challenging daytime conditions. Here, I studied the orientation precision driven by this flexible cue integration in the du

Parkinson’s disease (PD) is the most common neurodegenerative disorder, characterized by slow progressive loss of dopamine (DA) neurons in the substantia nigra, located in the ventral midbrain. Although the relatively focal degeneration in PD makes it a good candidate for cell-based therapies, obtaining cell source on large scale clinical application remains a challenge. It has now been shown that

This thesis studies the processing of null objects in the L2 English of two groups with a similar L1 background, Brazilian Portuguese and European Spanish native speakers. Previous research (Alamillo, 2009; Sainzmaza-Lecanda & Schwenter, 2017) reported similarities and contrasts in the two languages regarding null object expression. However, research on null objects lacks a fuller perspective

Rangitoto är en vulkanö som ligger nordost om Auckland, Nya Zeeland, och tillhör Aucklands vulkaniska fält (AVF) som består av ca 50 utdöda monogenetiska vulkaner. Eftersom Rangitoto har egenskaper som skiljer sig från de andra vulkanerna i området tror man att området genomgått en förändring och gått in i en ny fas. Det var ca 500 år sedan Rangitoto senast hade utbrott och eftersom storstadsområdRangitoto is a volcanic island, located northeast of Auckland, New Zealand, and belongs to Auckland Volcanic field (AVF), which consists of c. 50 extinct monogenetic volcanoes. Since Rangitoto has characteristics that makes it different from the other volcanoes in the area, it is believed that the volcanic field has undergone a change and entered a new phase. Rangitoto had its latest eruption abou

The rapid growth of photovoltaic (PV) deployment has raised concerns about the management of end-of-life PV modules, particularly crystalline silicon (c-Si) technologies approaching the end of their service life. Although PV systems contribute to renewable electricity generation, the increasing number of ageing modules poses environmental, technical, and resource-related challenges regarding wheth

The market for luxury fashion brands has been expanding rapidly since 1990 and continues to do so even today as young adults consume more luxury fashion goods. The growth in terms of consumption can be affected by different factors, like digitalisation and the use of social media, globalisation, preference and pressure to follow trends and idols etc. However, the factors that affect the buying int

Based on a realist conceptualization of interests, this paper explores how commercial and scientific priorities appear to have converged and diverged during the development of the antidepressant Zelmid. The drug represents the first of the selective serotonin reuptake inhibitors (SSRIs) to reach the market. Zelmid was synthesized in 1971 and launched by the Swedish firm Astra in 1982, but subseque

OBJECTIVES: To identify the lowest sensitivity and specificity that physicians and the general population consider acceptable for medical artificial intelligence (AI), relative to current human performance.METHODS: In a nationwide, cross-sectional survey in Sweden, 2025, random samples of 500 physicians and 500 adults from the general population were mailed a questionnaire presenting three vignett

Objectives: This study aimed to assess the relationship between dietary intake and disease outcomes in patients with radiographic axial spondyloarthritis (r-axSpA), focusing on inflammation and disease activity, while also evaluating other health outcomes, and to compare dietary intake between patients and controls. Method: In a cross-sectional analysis, we studied 295 patients with r-axSpA (modif

Background: The recommended treatment for hyposmia (a clinically reduced sense of smell) is olfactory training using odor containers that the patients smell twice a day for several weeks. Adherence to the olfactory training regimen is, however, generally low. We aimed to investigate if a new form of odor delivery, using scented nasal inserts, could enhance adherence to olfactory training by allowi

BACKGROUND AND PURPOSE: Although there have been numerous publications on lumbar disc herniation (LDH) treated surgically, there has been little interest in sex differences. It has been shown in many studies that sex differences may be important in certain diseases. We therefore reviewed consecutive register material from one institution for possible gender differences in pre- and postoperative pa

Xylose fermentation in yeast has been a target of research for years, yet not all the factors that may affect xylose fermentation perfomance of yeast strains are known. In this study, the mutant S. cerevisiae strain TMB 3400, which has good xylose fermentation properties, was compared with its parental strain to examine the factors behind the improved xylose utilization at protein level. The prote

Cue-conflict experiments were performed to study the compass calibration of one predominantly diurnal migrant, the dunnock (Prunella modularis), and two species of nocturnal passerine migrants, the sedge warbler (Acrocephalus schoenobaenus), and the European robin (Erithacus rubecula) during autumn migration in South Sweden. The birds' orientation was recorded in circular cages under natural clear

OBJECTIVE - Whole-grain foods are touted for multiple health benefits including enhancing insulin sensitivity and reducing type 2 diabetes risk Recent genome-wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) associated with fasting glucose and insulin concentrations in individuals free of diabetes We tested the hypothesis that whole-grain food intake an
