Aims. We study the origin of tail-like structures recently detected around the disk of SU Aurigae and several FU Orionis-type stars. Methods. Dynamic protostellar disks featuring ejections of gaseous clumps and quiescent protoplanetary disks experiencing a close encounter with an intruder star were modeled using the numerical hydrodynamics code FEOSAD. Both the gas and dust dynamics were taken int
Haemophilia A and haemophilia B are congenital X-linked bleeding disorders caused by deficiency of coagulation factor VIII (FVIII) and IX (FIX), respectively. The preferred treatment option for patients with haemophilia is replacement therapy. For patients with severe disease, prophylactic replacement of coagulation factor is the treatment of choice; this has been shown to reduce arthropathy signi
Intralocus sexual conflict arises when the expression of shared alleles at a single locus generates opposite fitness effects in each sex (i.e. sexually antagonistic alleles), preventing each sex from reaching its sex-specific optimum. Despite its importance to reproductive success, the relative contribution of intralocus sexual conflict to male pre- and post-copulatory success is not well-understo
β-Galactose derivatives have recently been reported to selectively inhibit galectin-3, and a library of O3-arylated galactosides with varying substitution patterns was designed to study such inhibitions further. The O3-arylated galactosides were synthesized using diaryliodonium salts under mild and transition metal free conditions, providing the target products in moderate to good yields. An O3-tr
In the search for new pharmaceutically active compounds, it is recognized that Nature produces structurally different compounds in a great variety. By having the compounds or extracts tested in defined systems, new drugs or more often leads (a compound that has an interesting but moderate activity) can be found. When a lead is found, structurally similar compounds with modified functional groups a
Popular Abstract in English A food web is a network diagram that describes which species that eat each other in nature. Such networks in marine environments e.g. show that cod eat herring, sprat, and sandeel - and that these eat numerous other species. Understanding of these relationships is a fundamental scientific problem, which can be used to assess the consequences for the stocks when we e.g. This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size. Each population resolves size-structure through a size-spectrum containing the individual
Popular Abstract in Swedish Ända sedan Charles Darwin 1859 publicerade Om arternas uppkomst har just frågan om hur en art delas i två varit en central del av evolutionsbiologin. Darwin hade under resorna på HMS Beagle iakttagit hur bland annat härmtrastar och finkar på Galápagos varierade mellan öarna och drog slutsatsen att flera närbesläktade arter inom grupperna delade samma ursprung. Darwin beThe process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. Speciation in sympatry, i.e. without any isolation between the

When developing software-intensive products for a market-place it is important for a development organisation to create innovative features for coming releases in order to achieve advantage over competitors. This paper focuses on assessment of innovation capability at team level in relation to the requirements engineering that is taking place before the actual product development projects are deci
There is currently a shift in the healthcare sector moving towards remote monitoring, meaning that monitoring of diseases and other issues is moving out of hospitals and into people's homes with the use of medical technology. One of the fastest-growing at-home monitoring solutions is the ECG device, especially due to the fact that cardiovascular diseases are the leading cause of death worldwid
What? A Backpack concept in co-operation with Swedish outdoor manufacturer Fjällräven. The backpacks are to be used by travelers, trekkers and other active people with a need for a lager carrying capacity. How? The packs should build on the heritage of the Fjällräven brand while being modern and express innovation as well as continuity, functionality and simplicity. Multifunctional While the produ
The application of digital twins in the city setting is emerging, the massive amounts of data and algorithms used raise the concern of algorithmic bias. This research focuses on examining how city scale digital twin practitioners prioritize the pragmatic, ethical, and moral domains in data management processes and when encountering algorithmic bias. It aims to provide insights for practitioners an
The long-term objective within the wave energy industry is to deliver large-scale wave energy farms connected to large national power grids. However, this objective cannot be reached with today’s wave energy technologies at their current maturity levels. This has created a need within the industry to identify alternative development paths—in this thesis referred to as off-grid market opportunities
The interface between wurtzite and zinc blende InP has been identified as type-II, where electrons gather on the zinc blende side and holes on the wurtzite side of the interface. The photoluminescence resulting from recombination across the interface is expected to be long-lived and to exhibit non-exponential decay of emission intensity after pulsed excitation. We verify this prediction using time
Hybridization is increasingly recognized as an important evolutionary force. Novel genetic methods now enable us to address how the genomes of parental species are combined in hybrid lineages. However, we still do not know the relative importance of admixed proportions, genome architecture and local selection in shaping hybrid genomes. Here, we take advantage of the genetically divergent island po
Packaging design is vital in the consumer product industry. This is why the recent consumer preferences for locally produced and organic food need to be met by product and package producers in the packaging design process. The purpose of this study is to understand how packaging design is managed in food supply chains with a special focus on organic and locally produced food in Sweden. It also ide
Previous theoretical work on range expansions over heterogeneous environments showed that there is a critical environmental gradient where range expansion stops. For populations with freely recombining loci underlying the trait under selection (hereafter, “adaptive loci”), the critical gradient in one-dimensional habitats depends on the fitness cost of dispersal and the strength of selection relat
Natural selection has produced diverse vision systems, from simple patches of photoreceptors to complex camera eyes, representing just one set of evolutionary outcomes. Computational evolution offers a way to systematically test hypotheses, isolate individual factors, and ask the “why” questions behind vision. We recreate vision evolution by coevolving eyes and behaviors in embodied agents and use
