RNA-seq has become a revolutionary tool for genome-wide gene expression analysis, opening new possibilities for research. This study focuses on using RNA-seq data for variant calling at Single Nucleotide Polymorphisms in a non-model organism, the bank vole. Variant calling from RNA-seq can for example be used for Allele-Specific Expression (ASE) analysis which sheds light on the impact of genetic

Nedbrytarsvamparnas arvsmassa ger oss ökad kunskap om deras Livsstil Saprotrofiska nedbrytarsvampar spelar en mycket viktig roll i kolets kretslopp. De får näring och energi genom att bryta ned dött växtmaterial i marken, till exempel döda kvistar och löven som faller på hösten. I nedbrytningsprocessen frigörs kol och andra näringsämnen som tas upp av svamparna, men kol avges även till atmosfären

En insektshjärna i ett kräftdjur Alla djur navigerar på något sätt. Men hur navigerar de, vad använder olika djur för att navigera genom världen? Det kan till synes verka som en trivial sak, bara gå i rätt riktning. Men hur vet man vad som är rätt riktning? Det har visat sig att det finns många olika sätt att veta om man ’navigerar rätt’. Insekter framför allt använder sig av alla möjliga typer aThe Central Complex (CX) is a highly conserved brain region at the center of the arthropod brain. It is believed to be the navigational center with a special neural circuit called the head direction system. The head direction system is the neural basis for a typical navigational strategy called path integration. Path integration requires the animal to have an external compass like the sun and an i

This thesis is dedicated to exploring and understanding public reactions within negotiated peace settlements based on social media data. Concretely, to modeling public opinion and sentiment within the context of the Colombian peace process using a curated dataset of N= ~1.3 million user comments expressing discord on 15,509 Facebook posts, throughout three years (2020-2022). A critical period embr

Food availability is known to influence animal distribution and abundance, playing a crucial role in population dynamics. However, this correlation remains somewhat unclear due to interactions with several other factors such as climate, predation pressure, competition, or even human influence. Therefore, understanding the mechanisms underlying these processes is crucial for ecologists to effective

Arvegods armchair which has its roots in the sustainable design tradition, is a journey through the eternal appeal of locally sourced materials. Bringing inspiration from the enduring bonds we create with treasured items, the user incorporate handcrafted linen textiles that evoke sentiments of love and workmanship from generations. The design encourages users to incorporate their own stories into

High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion. As a result, coherent eXtreme UltraViolet (XUV) radiation is emitted in the

The Jordanian Christian community is, in many aspects, a unique case within the MENA region. Mostly neglected by scholars and the mainstream public alike, it is perceived as unproblematic due to the institutional guarantees granted by the Hashemite regime, and the absence of apparent existential threats. Nonetheless, the copious influx of refugees from neighboring “sectarianized” contexts, the alw

Avståndet mellan produktion och konsumtion av livsmedel är långt. Dagens komplexa matsystem har försvagat vår relation till råvarors ursprung och dess värde. Industrier hamnar allt längre bort i periferin och blir otillgängliga för stadens invånare. Med växande befolkning och ökat livsmedelsbehov krävs alternativa och transparenta former av matsystem som grundar sig i naturens egna processer. TåThe distance between production and consumption of food is big. Today’s complex food systems have weakened our relationship with the source of raw materials and its value. Industries end up the periphery and becoming unaccessible to people in the city. With a growing population and increased food demand, alternative and transparent forms of food systems are required, grounded in nature’s own proce

Debatten om en hejdlös rivningskultur i Sverige har börjat ta fart de senaste åren. Utöver samtidens klimatfrågor som präglat kritiken om resursslöseri och utsläpp har även röster börjat höjas för historiska och kulturella värden som går förlorade. Viljan och förmågan att bevara befintlig arkitektur i Sverige har inte varit stark historiskt sett och fortsätter inte heller att vara det i vår samtidThe debate concerning the widespread demolition-culture in Sweden has sparked during recent years. Beside questions regarding climate change, waste of resources and emissions, voices have also started to rise for the historic and cultural values that are being lost. The will and capability to preserve existing architecture in Sweden hasn’t been strong historically and continues not to be so in mod

A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. It was established that stars with mK ≤ 16 can be observed and then they become

Maarten van Heemskerck’s St. Lawrence Altarpiece came to Sweden and Linköping Cathedral in the early 1580s. Around 50 years later, its design was copied by Johan Werner the elder for the altarpiece in Skänninge Vårfrukyrka, within the same diocese. The aim of this thesis is to map and contextualize discrepancies between the two altarpieces, doing so with the following research question: What diffe

This project looks at the potential of integrating the human perception and specifically our own perception of scent into the design process. To create something unique, valuable and potentially tangible with a powerful perception that is the exact opposite, intangible. In my Thesis I explored different uses cases, went on a sensual experiences myself to encounter the enriching potential,

During the Edo Period of Japanese history, many loanwords entered the Japanese language through communication with the Dutch. Now, 164 years after the last significant linguistic exchange took place between the Dutch and the Japanese, it is interesting to see what lexical influence still exists in contemporary modern Japanese and which loanwords have fallen out of use. Therefore, the aim of this b

Lipid nanopartiklar, förkortat LNP, används bland annat vid cancerbehandling och vaccinutveckling. Deras funktion är att transportera och skydda verksamma ämnen såsom antikroppar, proteiner och peptider. Ett välkänt exempel är coronavaccinet, där LNP transporterar mRNA och skyddar det från att brytas ner i kroppen. Lipid nanopartiklar består av olika lipider: positivt laddade, fosfolipider, kolestOver the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. Specifically, Polysorbate 80 (P80), a
