Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t
Both studies on and the application of GIS-systems during several disastrous events has shown a potential of the technology to facilitate for decision makers to make quick and suitable decisions to limit the impact of an event. In Sweden the primary responsibility for a crisis is held by the municipality in which the crisis occurs, which motivates an interest in investigating how GIS can support m
The main objective of this study is to contribute toward a comprehensive understanding of the superradiance problem in a short wavelength regime ($100$ to $100$ eV). In this regime, superradiance is influenced by Auger effect which would compete with normal superradiance process, and we want to study if it is possible to generate ultra-short pulses on the femtosecond or attosecond timescale using
Virus capsids shows promise within a wide variety of applications. However, the current lack of understanding about their self-assembly limits their usefulness. A study of the amino acids relevant for their assembly would be of great use by giving insight to the mechanic behind it. Since the number of proteins involved in each capsid is so big, there is a need for a reporter system enabling easy a
One fifth of the energy consumed by buildings in Sweden is by those built before 1945, many of them constructed from solid masonry walls. Improving their heating energy consumption is a challenge we must face in light of human’s impact on climate change as well as increasing energy costs. Improving thermal performance can be achieved with many insulating materials however the environmental impact
Restidskvot används som ett mått över kollektivtrafikens attraktivitet, många kommuner delar viljan att göra kollektivtrafiken just attraktivare för att öka andelen resenärer. Stockholms län visade i en rapport för över 25 år sedan ett samband mellan restidskvot och kollektivtrafikandel. Den här rapporten undersöker huruvida ett liknande förhållande existerar för medelstora kommuner och hur det saTravel time ratios are a popular way to measure the attractiveness of public transport. There is a demand within the Swedish municipalities for ways to make public transport more popular and increase the number of passengers. This study investigates if a connection between the ratio of travel time and the share of passengers travelling by public transport can be shown for medium sized municipaliti
Populärvetenskaplig sammanfttning: När man vill bestämma åldern på en bergart finns det flera olika metoder. En av de senaste och mest sofistikerade metoderna är den så kallade 40Ar/39Ar-metoden. En bergart är uppbyggd av flera olika mineral. Nästan alla mineral innehåller kalium (K+) i olika stora mängder. Kalium (K+) sönderfaller radioaktivt till argon (Ar) som är en ädelgas. Vid 40Ar/39Ar-daterThe traditional opinion about the Scandinavian Caledonian Mountains is that it formed in two major events; The Early Finnmarkian phase and the Later Scandian phase. However 40Ar/39Ar geochronology carried out in the Seve Nappe Complex yielded intermediate ages which rather indicates that there has been a continuous breakdown of the Baltoscandian miogeocline. As the nappes where emplaced upon the B
Seveskollkomplexet i de norra delarna av Sareks nationalpark, Kaledoniderna, kännetecknas av stora metamorfa kontraster. Sarektjåhkkåskollan, vars litologier är bäst bevarade, finns emellan två eklogitiserade skollor, Mihká- och Tsähkkokskollorna. I en nyckelposition mellan Sarektjåhkkåskollan och Tsähkkokskollan finns Sierggavággeskollan. Denna skolla har upplevt en betydligt lägre metamorfos, i The Sierggavágge Nappe (SiN) belongs to the Seve Nappe Complex (SNC), which is the tectonic unit that forms the topographic backbone of the Scandinavian Caledonides. The rocks of the SNC derive from the Vendian- Ordovician passive continental margin between cratonic Baltica and the Iapetus Ocean. This passive margin underwent stretching over at least 80 Ma and a complex orogenic evolution during t
Quantum memories are used for storing the quantum mechanical states of photons and release identical photons at a later time. This has many applications within the field of quantum computing and is also essential in order to achieve long range quantum communication and cryptography. In this thesis Atomic frequency comb (AFC) quantum memories were investigated. In particular, three-level memory sch
There is no doubt that the United States of America has used death penalty as a method of punishment in their legal system since the 17th Century. This essay is going to seek to explain why the United States of America has not yet abolished the death penalty; furthermore, it will discuss why they decided to resume the temporary suspension of the death penalty throughout the years 1966-1976. There
Sveriges och Europas befolkning blir allt äldre samtidigt som färre föds. Med andra ord ska allt färre yngre människor försörja allt fler äldre. Den 15 december 2008 infördes nya svenska regler för arbetskraftsinvandring från tredjeland. Reformen innebar att det gamla systemet där ansökningar om arbetstillstånd först prövades mot behovet på den inhemska marknaden, den så kallade arbetsmarknadsprövThe Swedish and European population is aging and fewer are born. In other words, fewer young people have to provide for an increasing number of elderly people. On December 15 2008 new Swedish rules for labour migration from third countries were introduced. The old system where an application for work permit was first assessed according to the needs of the domestic market, the so-called ”arbetsmark
Streaming applications are often described using dataflow actor models with a fixed network structure, allowing for static analysis and efficient hardware implementation. However, this fixed structure hinders scalability and design space exploration. This article investigates a representative dataflow toolchain, the StreamBlock compiler for the CAL actor language, along with its Actor Machine (AM)
In this evaluation of the international legal standing of the right to reparation and its practical implementation at the national level, Christine Evans outlines State responsibility and examines the jurisprudence of the International Court of Justice, the Articles on State Responsibility of the International Law Commission and the convergence of norms in different branches of international law,
Urbanisation, digitalisation and emerging technologies are reshaping young people’s relationship with the outdoor environment. We investigate how everyday outdoor experiences and spaces support adolescent wellbeing, understood as both feeling good and functioning well. Adolescents, at a pivotal stage in life, are particularly sensitive to environmental factors that influence their wellbeing. We co
A time-consuming yet mandatory step during in vitro sexual propagation of orchids is the treatment of seeds with a disinfecting solution that also serves to scarify the seeds. If the seeds are not properly disinfected, microorganisms grow within the culture vessel, thus reducing the efficacy of the process and burdening the operation with unnecessary materials and labour. On the other hand, a long
Advancement of aqueous zinc-ion batteries (AZIBs) for practical application is limited due to the inferior performance of the existing cathode. Herein, we demonstrate rational design and synthesis of an oxygen vacancy-rich low-valent vanadium-based spinel cathode (OV-ZnV2O4) for the fabrication of high-performance AZIBs. ZnV2O4 having an urchin-like morphology with nanorods ∼19 nm in diameter
Aqueous zinc-ion batteries have emerged as strong contenders for sustainable energy storage; however, their widespread adoption is constrained by sluggish Zn2+ transport and suboptimal cathode performance. A rapid, energy-efficient solvothermal synthesis of Na2V6O16 is reported, and introduces cation vacancies via initial electrochemical engineering. This electrochemical pre-treatment generat
Experimental microbial ecology and evolution have yielded foundational insights into ecological and evolutionary processes using simple microcosm setups and phenotypic assays with one- or two-species model systems. The fields are now increasingly incorporating more complex systems and exploration of the molecular basis of observations. For this purpose, simplified, manageable and well-defined mult
