The Planes of Satellites Problem is an open question within the field of galaxy formation. It is based on the observations that the Milky Way's satellites, as well as those around the Andromeda (M31) galaxy, align in planes. This applies both to the satellites' positions lying close to the plane of best fit, and to the satellites' orbital planes aligning within a narrow angle. Such pla
Denna framställning behandlar ämnet surrogatmoderskap. Surrogatmoderskap innebär att en kvinna genomgår en graviditet för ett barnlöst pars räkning, vilka benämns ”det beställande paret”. När barnet föds överlämnas det till det beställande paret som således blir barnets sociala föräldrar. Genetisk sett kan barnet vara helt och hållet det beställande parets eget eller kan surrogatmodern även ha bidThe theme of this essay is surrogate motherhood. This is the practice whereby one woman carries a child for another woman. The other woman and her partner are called the commissioning couple. When the surrogate mother has given birth, the child is handed over to the commissioning couple. The commissioning couple may be the genetic parents of the child, or the surrogate mother may have contributed
If human rights are to be enjoyed by every person regardless of origin or nationality; if human rights are the rights of the human being under any circumstances, then the best way to gauge the quality and depth of our systems of protection of human rights will be to examine the extent to which these are enjoyed by their most genuine recipients: those deprived of wealth and citizenship, a home and

I takt med en ökande befolkningsmängd och den pågående digitaliseringsprocessen, finns det ett behov av en effektiv planeringsprocess. I Sverige finns det både nationella och internationella mål som berör detta. Detaljplaner är ett viktigt verktyg för att reglera planeringsprocessen. Vid nybyggnationer och förtätningar av städer krävs det att analyser utförs för att säkerställa att krav på buller,In line with an increasing population and the ongoing digitization process, there is a need for an effective planning process. In Sweden, there are both national and international goals that concern this. Zoning plans are an important tool for regulating the planning process. In the case of new constructions and densification of cities, it is required that analyzes are carried out to ensure that r
This thesis was done in collaboration with the department of Food Technology at LTH, Aventure AB, and Arwa Foodtech AB. The aim of the project was to develop the base for a baobab based, spoonable protein snack, comparable to quarg but free from ingredients of animal origin. At the time of writing, one of the biggest if not the biggest trend in the food industry is the replacement of animal-source
Popular Abstract in Swedish Dagens industriella system är inte långsiktigt hållbara. För detta behövs bland annat fundamentala förändringar av hur samhällets resurser används. Detta gäller den totala volymen som förbrukas men också vilka ämnen som sätts i omlopp i samhället. Därutöver behövs ett mer rättvist utnyttjande av dessa resurser. Industriell ekologi är den vetenskap som studerar de förändToday's industrial systems are regarded to have unsustainable characteristics. In order to acquire a more sustainable state, fundamental changes are needed in the qualitative and quantitative aspects of the resource flows associated with such systems. These need to go hand in hand with a more equitable distribution of the benefits and burdens associated with such resource use. The identification a
Chlorophyll-a (Chl-a) is one of the critical water quality indicators that shows the eutrophication status of aquatic ecosystems. As the largest lake and a well-known attraction in middle Europe, Lake Balaton contributes 70 % or more of local economy through tourism, while also maintaining a unique biodiversity. Therefore, long-term monitoring of water quality is essential for its effective manage
Background: Vasovagal syncope (VVS) is a common yet challenging condition with limited effective treatments. Elastic compression stockings (ECS) have been proposed as a potential therapy, but their real-world effectiveness remains unclear. Objectives: This study sought to compare the effectiveness of lower extremity compression with thigh-high ECS vs sham stockings for the prevention of VVS recurr
Corrosion of embedded steel reinforcement is the prime influencing factor that deteriorates the structural performance and reduces the serviceability of reinforced concrete (RC) structures, especially during earthquakes. In structural elements, RC columns play a vital role in transferring the superstructure's load to the substructure. The deterioration of RC columns can affect the structures' over

Understanding how affect interacts with the neural dynamics of syntactic processing remains an open question in neurolinguistics. While syntactic anomaly detection has been extensively characterised through electrophysiological markers such as LAN and P600, the extent to which pervasive affective states, or moods, modulate these components is still poorly understood. Existing studies suggest that
Background Supply Chain Management is becoming increasingly more important to organizations in the post Covid-19 era. Managing Supply Chains is also moving towards finding data-oriented ways of working, and companies are making substantial investments in getting digital information systems to integrate with their ways of working. Simultaneously, Artificial Intelligence has become a well-discussed
Popular Abstract in Swedish Den svenska grundskolan har under de senaste åren genomgått och genomgår fortfarande en stark utveckling inom ramen för den allmänna decentraliseringen i samhället. Beslut och ansvar läggs allt längre ner i organisationen. De krav som ställdes på en skolledare tillbaka i tiden var i första hand att han skulle vara administratör och den som bevakade att skolans verk-samThe issues of the study are: How do the assistant principals face the work as school leaders? Which demands of competence do the new school leaders face? Which needs of competence development exist for new school leaders? In the school studied the organization of the management was changed from one principal and one director of studies to one principal and six assistant principals. All of these we
A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. The evolution model poses a moving boundary value pr

Avhandlingen inkluderar ett antal studier som jämför svaga och goda läsare med avseende på olika aspekter av visuell ordavkodning. Drygt 100 svaga
Gas turbine maintenance is crucial due to high cost for the replacement of its components and associated loss of power during shutdown period. Conventional scheduled maintenance, based on equivalent operating hours, is not the best alternative as it can require unnecessary shut downs. Condition based maintenance is an attractive alternative as it decreases unnecessary shut downs and has other adva
Popular Abstract in Swedish Proteiner är biologiska molekyler som kan utvinnas ur olika bakterier, svampar, djur och människor. I sin naturliga miljö bidrar de bl. a. till att katalysera (snabba på) olika kemiska reaktioner (enzymer), att sköta transporten av olika molekyler, bidra till immunförsvaret och tillväxtkontroll (hormoner). Upptäckten att proteiners olika funktion kan uttnyttjas i många The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. NMR spectroscopy revealed changes in the relaxation properties of Ala and Thr methyl groups in lysozyme, indicating compression of the enzyme as a consequence of pr
Popular Abstract in Swedish I Sverige analyseras omkring 40 000 DNA-prover från brottsplatser varje år. DNA-profilerna jämförs mot DNA-profiler från misstänkta personer och kan på så vis användas för att knyta en person till ett brott. Alla typer av kroppsvävnader kan analyseras, såsom blod, saliv och hudceller. Vanliga bevismaterial är cigarettfimpar, flaskor, burkar och kläder. De material som cDNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. In this work, pre-PCR processing was applied to improve
