The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. The glacial history of Vombsänkan, which is controlled by sequential geological events such as active ice-margin and stagnant ice, formation of dead ice as well as
With aging populations, unequal access to care, and shortages of staff, healthcare systems today are facing many challenges. Technology advancements, with artificial intelligence (AI) in particular, have been one of the main drivers of innovation in multiple industries. Although the healthcare sector is moving slower compared to other industries, there is great potential for relieving healthcare w
In most manufacturing companies, it is necessary to carry inventory to a greater or lesser extent in order to disconnect the activities in the supply chain that are not conducted at the same pace. This way, a smoother flow through the chain, from raw material extraction to arrival at the final customer of a finished product, is facilitated. However, different parts of a company often have conflict
The interactions between airway epithelial cells (AECs) and dendritic cells (DCs) play an important role in the sensitization towards airborne allergens. Not much is known about the underlying mechanisms and novel in vitro approaches are needed, which include the different involved cell types in order to investigate what happens at the molecular level during sensitization. In this project, one aim
Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m
The aim of this study was to understand the experiences that social workers in the social services child protection unit has regarding their working conditions and how they reflect about their workload, staff turnovers, wellbeing in regards to the role of a social worker. Our qualitative study was based on seven interviews with social workers who worked in a middle-sized municipality in Skåne. Th
In the pursuit of a system capable of measuring pain signals in humans we propose a method to differentiate those signals related to pain from those which are not. We performed a time-frequency analysis using the Gabor transform to have complete information about the spectrum and its behaviour through the time to study the main differences over the evoked potentials provoked by both nociceptive an
When viewing moving objects in videos the movement of the eyes is called smooth pursuit. For evaluating the relationship of eye tracking data to the moving objects, the objects in the videos need to be detected and tracked. In the first part of this thesis, a method for detecting and tracking of moving objects in videos is developed. The method mainly consists of a modified version of the Gaussian
A common approach to treat respiratory diseases is with adhesive powder mixtures. These are dispersed into an aerosol upon inhalation. It has been found that the performance of such mixtures can be improved by adding fine particle lactose, but exactly why is yet to be established. Several theories have been proposed by previous studies, but the fundamental mechanism is still unknown. This study w
S:t Jacobs church and burial site from medieval Lund was excavated in 1983. There has until now not been any osteological study and there is nearly no information about the church. To gain more information about the church and the burials, an osteological study has now been made. The analysis is based on aging and sexing the skeletons to enable a socio-economic discussion. 93 out of 320 excavated
The HIE-ISOLDE post accelerator at CERN has recently come online, en- abling the use of radioactive ion beams with energies of up to 10 MeV/u. An active target gaseous detector is under development for use in some of the experiments. The first investigation of the electron amplification stage with gas electron multipliers has been performed. To this end, a small prototype GEM detector was built an
For variable-frequency drives, the most common way to apply the desired power to an electrical motor is using PWM modulated signals. Due to high-frequency components, those signals give rise to reflections in the motor cables, radiated noise around the cables and acoustic noise in the motor. In order to avoid those problems, NFO Drives AB develops and produces an alternative to PWM modulation call
Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. The high-k films (Al2O3/HfO2) were formed by atomic layer deposition (ALD) as an alternative to silicon dioxide (SiO2) to proceed the scaling of oxide to low

The aim of our study was to examine the relationship between creativity and wellbeing. The material for our study has been gathered through a questionnaire with self-assessment at one of Scandinavia's largest companies in the hotel industry. The questionnaire consisted of The organisational questionnaire (GEFA) and The measurement of wellbeing. In the study 90 questionnaires was distributed in
Objectives: The only treatment with curative potential for distal cholangiocarcinoma (dCCA) is radical surgery which can be complemented with adjuvant chemotherapy. The aim of the present study was to perform an independent external validation of a prognostic model for 3-year overall survival based on routine clinicopathological variables for patients treated with pancreatoduodenectomy for dCCA. M
This article investigates the performance of several residuals for the Cox proportional hazards regression model to diagnose the influential observations. The standardized and adjusted forms of residuals are proposed for Cox proportional hazards regression model. In addition, Cook’s distance is proposed for both standardized and adjusted residuals. The assessment of different residuals for the ide
High-pressure homogenizers are prone to cavitation, which causes wear and influences breakup efficiency. However, the inception point, as well as the extent and intensity, depends on geometry, operation, and fluid properties. While several methods have been previously suggested to characterize cavitation in homogenizer valves (including ultrasonic methods), they have required highly specialized, s
Chronic wounds, particularly pressure ulcers, pose significant healthcare challenges, especially in the elderly population. This study presents an experimental murine model of chronically infected pressure ulcers using a single cycle of magnet-induced ischemic injury combined with infection by bioluminescent Staphylococcus aureus. The model addresses previous limitations in studying pressure ulcer
BACKGROUND: Lung cancer remains one of the most challenging diseases to treat due to its heterogeneity. Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) mutations are genetic drivers in numerous cancer types including lung adenocarcinoma (LUAD). Despite recent advances in KRAS-targeted therapies, treatment resistance and limited therapeutic options necessitate advanced preclinical models, such as
