Har du någonsin hört talas om en supernova? En exploderande stjärna som kastar ut högenergetiska partiklar. Inte nog med det så färdas även dessa partiklar genom hela galaxen. Galaxer är stora och endast några ut av partiklarna når vår jord. Vi kan finna dessa partiklar i en iskärna och på så sätt har forskare kunnat få tag på information som behövs för att kunna studera jordens magnetfält. Med inExtreme geomagnetic variations such as excursions where the magnetic poles shift, and return are not fully understood. 10Be, used as a proxy for the magnetic field studies has been proposed as a compliment to paleomagnetic models, allowing adjustments. LSMOD.2 is a sediment and volcanic based magnetic model encompassing the Laschamps excursion ~41 000 years ago. LSMOD.2 is limited due to lacking d

Sot är en produkt som kommer ifrån ofullständig förbränning av olika bränslen, som fossila bränslen och biogaser. Sot produceras därför, bland annat, i många av våra fordon, så sot släpps ut i stora mängder. Sot har en negativ påverkan på miljö och mänsklig hälsa. Det finns olika typer av sot. De som absorberar ljus bättre och har större klimatpåverkan kallas moget sot, medan sot med sämre ljusabsSoot is a known contributor to climate change due to its strong light absorption possibility. It has been shown that adding alkali salts during the soot formation reduces its soot absorption ability, and thus reduces its impacts, but the exact mechanics are not fully understood. This thesis aims to get a better understanding of the effects that salts have on soot. The salts used were sodium chlori

The Hummeln structure is a relatively recently confirmed impact structure located in the northeastern part of the province of Småland in Sweden (57.37347°N 16.25084°Ö). Due to its relatively recent confirmation, detailed petrographic studies regarding shock metamorphism and shock metamorphic features in the Hummeln-1 drill core are lacking. The drill core is the only drill core from the structure Det är ett allmänt känt faktum att det som orsakade det senaste massutdöendet och därmed slutet på dinosauriernas era var ett meteoritnedslag. Mindre känt är kanske det faktum att meteoritnedslag faktiskt är ganska vanligt förekommande sett ur ett geologiskt perspektiv. Lyckligtvis är konsekvensen av dessa väldigt sällan ett massutdöende, men meteoriter kan ha en stor påverkan trots det. Ett exemp

To continue the development of novel therapeutics to treat bladder cancer, a reliable model for preclinical testing of treatments and studying of the disease mechanism is essential. Ex vivo culturing of precision cut tumor slices (PCTS) provides a model that can retain the tumor architecture and its tumor microenvironment including the immune cell compartment, but data on PCTS based on bladder tum

The historically rapid growth of modern cities has a tearing effect on our planet, which requires a systematic transformation from linear to circular resource usage and consumption. Scientists and decision makers world-wide propose Circular Cities as a part of the solution, but empirical evidence and theoretical models of their practical implementation is lacking. This study explores the framework

Punktlighet och förseningar inom järnväg är något som står högt upp på agendan i dagens samhälle. Med en infrastruktur som är i ett stort behov av underhåll samtidigt som trycket på klimatsmarta transportlösningar bara ökar, blir punktligheten och framkomligheten inom järnvägen avgörande. Med en total punktlighet på ungefär 90% finns det mycket att göra. En av järnvägens infrastrukturproblem är spPunctuality and delays within the railway system are of utmost concern in today’s society. With an infrastructure in a dire need of maintenance and the increasing pressure for environmentally friendly transportation solutions, punctuality and accessibility within the railway system becomes crucial. With an overall punctuality rate of approximately 90%, there is much to be improved. One of the prob

Bloodstream infections (BSIs) are among the top causes of death in Europe and as such, a serious health concern.
