The purpose of this study was to investigate the predictive capabilities of hand-calculation methods and simulations using FDS in understanding the behavior of a tunnel fire in terms of temperature and incident radiation. Additionally, the study aimed to examine the repeatability of a large-scale fire experiment. The research commenced with the execution of three similar experiments, further calle

Swedish public service radio has during its almost 100 years undergone several transformations due to technical, societal and cultural changes. A transformation still in motion can be attributed to the arrival of the internet, the digitalization of the recording, storage and distribution of sound, as well as the fast paced evolution of the global media landscape. When the mp3-file and the internet

Climate change forces organisms to adapt to new habitats with migratory birds facing unique challenges, especially when they initiate the migratory behaviour to gain mass for migration. Many bird species adapt to their ancestral latitudes by changing their behaviour and physiology to the photic environment. Current predictions indicate that climate change can also limit range shift capacity due to

This study investigates and describes the Haemosporidian parasite composition of the host bird community in the Ammarnäs area from 1999 to 2020, along with the effect of avian malaria infection on host body condition, based on a data set comprising body measurements and infection status for the Plasmodium, Haemoproteus, and Leucocytozoon genera in captured birds from five sample years, and also a

All organisms are made up ofcells, the smallest functional unit of life. While organisms such asplants and animalscan consist of trillions of cells, others consist of just one cell.One group of unicellularorganisms is called bacteria. Because oftheir small size, bacteria and other microscopic small organisms are classified as microorganisms. In nature, mostbacteria do not live as single cells. Th

Anna Sundgren, MOBM02 September 23 - January 24, Department of Biology, Lund University Baby infection as Alzheimer´s disease protection? The characteristic pathology of Alzheimer’s disease (AD) includes accumulation of amyloid-beta protein as plaques, and tau-protein as tangles in the brain. Another important feature of the disease is neuroinflammation. One important risk gene for AD is the apo

This study aimed to investigate various properties associated with human protein deletions, encompassing deletion length and position, amino acid composition, flanking amino acid composition, functions of the host proteins, the functional role of the corresponding gene, relative positioning with protein domains, protein structure within the deletion region, and conservation, to identify potential

Bakgrund: Meningsfulla aktiviteter är sammankopplade med hälsa och välbefinnande. När människor åldras eller deras förutsättningar för aktivitet förändras kan förlusten av meningsfulla aktiviteter leda till ohälsa. Äldre personer kan både förlora förmågan att utföra aktiviteter, men också finna att förutsättningar till aktivitetsutförande förändras när hemmiljö och äldreboende blir ett. Syfte: SyfBackground: Meaningful activities are interconnected with health and well-being. When people age or their circumstances for engaging in occupations change, a loss of meaningful activities can occur, leading to illness. Older people may not only lose the ability to perform occupations but may also find that their circumstances for engaging in occupations change when the home environment and nursing

Inom vägbyggnad har det skett minimala förändringar av byggmetodiken sedan det romerska imperiets tid, detta fram till att McAdam dök upp. McAdams filosofi handlade om att bygga en ogenomtränglig och upphöjd överbyggnad i förhållande till de omgivande ytorna för att minimera vatteneffekterna på konstruktionen. Med hänsyn till dagens klimatförändringar krävs dock implementering av nyare konstruktioIn road construction there have been minimal changes to the construction since the time of the Roman empire, until the time of McAdam. McAdam’s philosophy included an impermeable and raised superstructure in relation to the surrounding surfaces to minimize the water effects on the construction. In view of today's challenges with climate change, however, new thinking is required in road constru

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
