Summary . Pied Flycatchers Ficedula hypoleuca are known to be victims of nest killings in contexts of competition for nest boxes. However, there is only anecdotal information on their opposite role as perpetrators of nest takeovers and occasional killings of other songbirds. Over 31 years we examined whether competition with Great Tits Parus major over nest box ownership is a significant source of
Splicing and translation are two of the key steps of post-transcriptional regulation of gene expression. Their tight regulation is essential for development, whereas their deregulation is involved in cancer pathogenesis. Nevertheless, many of the molecular mechanisms controlling these processes are still unknown. Hence, the main aim of this thesis is to elucidate novel regulatory mechanisms that a
Background: The Hawthorne Effect is the change in behaviour by subjects due to their awareness of being observed and is evident in both research and clinical settings as a result of various forms of observation. When the Hawthorne effect exists, it is short-lived, and likely leads to increased productivity, compliance, or adherence to standard protocols. This study is a qualitative component of an
Pepsin-like aspartic proteases (PAPs) are a class of aspartic proteases which shares tremendous structural similarity with human pepsin. One of the key structural features of PAPs is the presence of a β-hairpin motif otherwise known as flap. The biological function of the PAPs is highly dependent on the conformational dynamics of the flap region. In apo PAPs, the conformational dynamics of the fla
The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high, complicating efforts to quantify sink-source patterns across the entire region. Statistical models are increasingly used to predict (i.e., upscale) CO2 fluxes across large spatial domains, but the reliability of different modeling techniques, each with different specifications and assumptions, has not been asses
BACKGROUND: Central venous catheter (CVC) misplacement occurs frequently after right subclavian vein catheterization. It can be avoided by using ultrasound to confirm correct guidewire tip position in the lower superior vena cava prior to CVC insertion. However, retraction of the guidewire during the CVC insertion may dislocate the guidewire tip from its desired and confirmed position, thereby res
Värdering av obebyggd tomtmark för småhus kan ibland vara svårt då det saknas ett bra ortsprismaterial. Ännu svårare är att värdera tomtmark för småhus som är bebyggda med byggnader på ofri grund. Tomtmark med byggnader på ofri grund upplåtna med nyttjanderätter anses ha ett lägre värde än tomtmark som är obebyggd eller tomtmark som är bebyggd av fastighetens ägare. Det beror på att nyttjanderätteThe objective of this work is to examine the impact on value that a house on leasehold has on the underlying land in a partition ordinance. In order to build a foundation and create an understanding about houses on leasehold, partitiontools and different methods of valuation I undertook literature studies. The literature consisted of, among other things, preparatory work for FBL and the Court of A
Background: The role of physical therapists are affected by several aspects including the therapeutic relationship, inter-professional relations, workloads, autonomy and their relations to everyday tasks. In particular, the latter of these is a topic of interest in regards to Japanese physical therapists since healthcare in Japan has shown tendencies toward the adoption of new technology. This, th
Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate t
Det har uttryckts oro över ungdomarnas ständiga uppkoppling via sociodigitala teknologier och hur detta kan relateras till en upplevd försämring av unga människors välbefinnande. Få studier har fokuserat på totala användningen av både sociala medier och dataspel; eller har utforskat potentiella positiva samband mellan sociodigitalt deltagande (SDP) och ungdomarnas välbefinnande. Syfte: Den aktuellConcern has been voiced about adolescents’ instant connectivity via socio-digital technologies and how that relates to a perceived worsening of young people’s well-being. Few studies have focused on cumulative use of both social media and gaming; and/or exploring potential positive associations of socio-digital participation (SDP) and adolescent well-being. Objectives: The current study aimed to
Vid första anblick ger Villacañas intrycket av att vara en anspråkslös by i centrala Spanien. Den besitter inte de karakteristiska egenskaperna som så många andra byar i Spanien har; det tydliga historiska arvet, gamla byggnader, små krokiga gator och gränder. I Villacañas är det första man möts av, till stor del, övergivna dörrfabriker och industrikomplex. Byns arkitektur är beige, rödbrun och daAt first sight, Villacañas seems like a dull and unassuming village in the centre of Spain. In contrary to so many other Spanish villages, Villacañas doesn’t have a strong and visible historical heritage with narrow streets and old buildings. The first thing that meets your eye, when entering the village, is an avenue of abandoned door factories and industrial complexes. The architecture of Villac
Under de senaste fem åren har olika ekonomiska faktorer som påverkar bostadssituationen i Sverige ökat avsevärt, med skyhöga elpriser, bostadräntor och en hög inflation bl.a. Läget har gjort det omöjligt för främst unga, äldre eller människor i utanförskap att införskaffa en egen bostad. Samtidigt är landet ett av de länder som har flest ensamboenden i sina städer, vilket är en stor orsak till psyOver the past five years, various economic factors affecting the housing situation in Sweden have significantly increased, including skyrocketing electricity prices, housing interest rates, and high inflation, among others. This situation has made it impossible for primarily young people, the elderly, or individuals facing social exclusion to acquire their own homes. At the same time, the country
Solcellsparker blir både allt vanligare och allt större. I denna studie undersöks hur storleken och antalet transformatorer i en solcellspark påverkar dennas förmåga att leverera el. De rådande klimatförändringarna är en av de största utmaningar mänskligheten ställts inför. Fossil elproduktion är en stor bidragande faktor till utsläpp av växthusgaser globalt. Solceller ser ut att spela en avgöranThe main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated
Study purpose: This study explores how Floating Container Terminals (FCTs) located in the North and Baltic Seas can support the maritime shipping industry's growth while promoting sustainability. As freight transportation volumes rise and sustainability regulations tighten, ports face increasing demands to accommodate Ultra-Large Container Vessels (ULCVs) in an environmentally responsible mann
Klimatförändringar är antagligen en av de största utmaningarna i modern tid, där förhöjda halter av växthusgaser i atmosfären har förödande konsekvenser på jordens livsuppehållande system. Koldioxid är ansedd som den mest utsläppta växthusgasen, vilket har lett till ett ökat intresse för koldioxidinfångning. Ett sätt för att minska de förhöjda halterna av koldioxid i atmosfären är genom koldioxidiWith climate change being one of the greatest challenges of our time, interest in carbon dioxide removal and mitigation has increased, as a way of minimizing emissions. As a result, carbon capture has become a key focus in the industry. One of the most common chemical absorption techniques is carbon capture using hot potassium carbonate (HPC). This process operates at an elevated absorber pressure
PFAS are a group of persistent and harmful chemicals that are widely used in both industrial applications and consumer products. PFAS are commonly detected in the environment and pose health concerns. Adsorption by GAC is considered an effective treatment method for removing PFAS from water. After a certain period of operation, GAC requires high-temperature incineration as disposal method. Another
The purpose of this report is to investigate and compare two potato chip production lines to determine the optimal layout of the factories in order to maximize the chips' adhesion ability to seasoning. The hypothesis of this study is that the adhesive ability of chips is highly dependent on how warm they are when they are seasoned, with warmer chips having a stronger adhesive ability. This hy
In the present time, the rate of environmental degradation requires us to use all available means to avoid further damage and restore the environment to the best of our possibilities. Education is an important channel to promote environmentalism and sustainability, and to promote pro-environmental individual decisions, especially regarding consumption and purchasing patterns.
