Neuroblastoma (NBL) is the most common pediatric extracranial solid tumor and often manifests in the adrenal gland affecting the sympathetic nervous system. Despite many treatment alternatives, the risk of relapse remains, and the overall five-year survival is around 50 %. By downregulating major histocompatibility complex I (MHC-I), the NBL cells can evade the immune system affecting the function
III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. Although there is a lot of research about III-V nanowires, a gap in understanding anti
Alexander’s Disease is a progressive neurological disorder caused by a wide array of dominant, gain of function mutations in the GFAP gene. The disorder is characterized by the accumulation of GFAP in astrocytes, leading to the formation of protein inclusion bodies known as Rosenthal fibers. This results in a disruption of astrocytic function and the subsequent degeneration of white matter. Howeve
Objective: 1-2 ‰ of newborns in Sweden are identified with a permanent, habilitation- required hearing impairment at neonatal hearing screening. Traditionally, focus is on the child when diagnosed; the parents’ needs and concerns are not always recognised. The current study aims to elucidate parents’ narratives of their experiences of the process of diagnosis and habilitation of their child with c
This thesis examines how the performance of a rule based trading algorithm, the Golden Cross Trading Algorithm, and an Artificial Neural Network constructed algorithm, the Long Short-Term Memory, perform against each other and a buy- and-hold strategy, when trading on the equity market. The underlying assets will be nine large American tech companies, all listed on Nasdaq. In order to distinguish
Title: The Impact of the Pandemic and War on the State of Global Supply Chains Purpose: The purpose of the thesis is to outline the current state of global supply chains and global energy supply as a result of the Covid-19 pandemic as well as Russia-Ukraine war. Current energy and supply chain issues are explored and discussed based on existing theory on the topic. When the overall issues are cla
Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. If this is the case, dark matter can be produced at accelerators and detected indirectly by searching for missing momentum signals. LDMX will join this se
The use of cancer cell cultures, including immune cells, is essential in cancer research for developing immunotherapies in pre-clinical investigations. However, so far, a large number of animal-derived products are utilised in cell culturing, where experimental variations and reproducibility problems have been reported. Most studies have also only investigated the differentiation of monocytes into
It is difficult to definitively say who the greatest Formula One driver is. It is a subjective assessment and can depend on a variety of factors, including the driver’s skill, their results and accomplishments, their team and car, and the era in which they competed. Some of the most successful and highly regarded Formula One drivers include Michael Schumacher, Ayrton Senna, Lewis Hamilton, Alain P
Zooarchaeological studies have played a crucial role in understanding the pre-historic societies of Scania. The analysis of animal remains from archaeological sites has provided insights into the subsistence strategies, economic practices, and cultural beliefs of the people who lived in the region. Remains from horse, dog, wild boar, and man are commonly observed in offering and burial contexts. D
Aqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. At the site groundwater was previously used as a drinking water source consequently affecting the inhabit
When a fuel cell stack is assembled it is compressed to ensure gas tightness, and as a consequence, the Gas Diffusion Layer (GDL) will intrude into the channels of the Bipolar Plate (BPP). In this work, the GDL is studied in compression tests and through intrusion measurements. Based on the collected data from the measurements, an approximative method is developed to calculate the intruded profile
Att social isolering och ofrivillig ensamhet har negativa effekter på den psykiska och fysiska hälsan är ingen nyhet. Ensamhet är en folksjukdom. Och undersökningar visar att den ofrivilliga ensamheten har starka kopplingar till boendet och det egna hemmet. Tiden under Covid-19-pandemin har präglats hårt av uppmaningen om ”social distansiering”. Ännu mer tid har spenderats i eller i närheten av h
When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. It is currently a manual process where points from a virtual environment are transferred to
Ungefär en tredjedel av Sveriges befolkning är friluftsaktiva i skog- och mark minst en gång i veckan. Detta intresse ökar för varje år, och under Covid-19-pandemin nådde andelen friluftsintresserade nya höjder där femtio procent av Sveriges totala befolkning aktivt deltog i utomhusaktiviteter. Men, även fast intresse för utemiljöer och naturupplevelser finns, har alla inte samma möjlighet att ta
