Due to its low symmetry, β-Ga2O3 exhibits a strongly anisotropic optical response. As a result, the absorption spectra change with the polarization state of the incoming photons. To understand this phenomenon, here we calculate the complete electromagnetic wave equation solutions as a function of linear polarization angle and photon energy for β-Ga2O3 using its previously measured complex dielectr

Effects of pilot H2 injection on the thermoacoustic instability of premixed CH4/air flames were experimentally investigated with varied hydrogen injection rates and different injection strategies. The flames were stabilized on a swirl burner with a central pilot-fuel injection tube. The flame structure was captured using high-speed OH* chemiluminescence and OH-PLIF methods, while the CO and NOx em

In this study, the duality of adaptive capacity in aviation safety is examined, where the need for resilience of frontline workers conflicts with the expectations and assumptions of upstream entities, leading to system brittleness. We explore three critical categories: responsibilization, the application of practical wisdom in navigating challenging situations, and the unrecognized sacrifices that

Background We need to better understand the frequency and predictors of opioid use disorder (OUD) after first opioid prescription (OP). Methods We followed 1 516 392 individuals from the Swedish population born 1980-2000, from 1 July 2007, until 31 Dec 2017. We examined putative risk predictors with univariable and multivariable Cox Models and the potential causal effects of predictors by propensi

Excessive generosity with information about one's private life or the private lives of others, known as ”oversharing”, appears to be an oft-noted phenomenon in the context of ”new” media. I have previously studied this phenomenon in connection with mobile phone conversations in public places. After having eavesdropped on, or maybe rather overheard, such conversations more systematically, I offered

Plastics pollution is increasing every year in aquatic ecosystems and with it, an ever-increasing number of micro- and nano-sized plastic particles. It has been shown that these particles find their way into the food-chain after being consumed by organisms at lower trophic levels, such as the zooplankter Daphnia magna. Previous studies have shown negative effects on the reproduction, development,

This research is exploring policy coherence of energy, climate, and biodiversity policies on the case study of new hydropower developments in the Republic of Slovenia. A qualitative case-study approach utilising policy document analysis and interviews was chosen to conduct this research. This analysis revealed that policy objectives were coherent within policy sectors but not across policy sectors

This thesis has the purpose to increase the understanding of knowledge sharing between dispersed units of a large organization. By conducting a qualitative study with an abductive approach, consisting of a case study at Volvo Group where we looked into a cross-functional committee, we researched what the knowledge sharing processes look like and what barriers hinder the sharing of knowledge. We us

This thesis examines the concept of immersion concerning a physical space rather than a cinematic or virtual reality. The term has, within contemporary research of visual culture, often been ascribed to computer-generated realities in which the spectator is absorbed within a hermetically closed-off image space of illusion. Disconnected from the real, a critical aspect has been that the subject ten

Combined resistivity and time-domain direct current induced polarization (DCIP) measurements are traditionally carried out with a 50\% duty cycle current waveform, taking the resistivity measurements during the on-time and the IP measurements during the off-time. One drawback with this method is that only half of the acquisition time is available for resistivity and IP measurements, respectively.

A methodology for estimating the carbon balance across Scandinavian forests using remote sensing is presented. By estimating the gross primary production (GPP) and the ecosystem respiration (ER), and thereby, the net ecosystem exchange (NEE), using parameters that are routinely retrieved from satellite, it is possible to implement an operational model for obtaining large scale NEE. GPP is successf

The most frequently used animal models for Parkinson's disease (PD) utilize unilateral injection of 6-hydroxydopamine (6-OHDA) in the medial forebrain bundle (MFB), which results in total denervation of the dopaminergic nigrostriatal pathway. However, neuroprotective interventions in PD require models resembling earlier stages of PD, where some dopaminergic cells and fibres remain. The aim of the

Popular Abstract in Swedish Störd magsäcksfunktion är en vanligt förekommande komplikation bland den snabbt tilltagande populationen av diabetiker i världen, också inkluderande andra patient grupper så som de många patienter med diffusa besvär från magen (funktionell dyspepsi). Fördröjd magsäckstömning (gastropares) kan dels leda till en rad obehagliga symtom förknippade med födointaget (tidig mätAbnormal gastric motor function, a frequent complication among the increasing diabetic population of the world, also includes other patient groups such as those many patients with functional dyspepsia. These facts stress the need for a reliable, safe, cost-effective, and simple technique for measuring gastric emptying. To date the ultrasound technique for measuring gastric emptying has been regard

Two alternative hypotheses have been proposed to explain how social and genetic mating systems are interrelated in birds. According to the first (male trade-off) hypothesis, social polygyny should increase extrapair fertilizations because when males concentrate on attracting additional social mates, they cannot effectively protect females with whom the); have already paired from being sexually ass

This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta
