The original task for our final thesis was to solve issues that are connected with exercise on the International Space Station, ISS. Those issues are mainly centered on the conflict between scientific and human needs perfect micro gravity conditions versus the needs to physically challenge the human body. Also psychological matters were central to the project exercise for the sake of science versu
Purpose: The goal is to see what an innovation process can make for a package and learn to ron a development project with multiple stakeholders. Theory: The theory chapter strives to provide a picture of how the package works. What factoTs are important and what more a package can offer than just protection for the product? Describe how an innovation process can help a development process and exp
The main goal of this thesis is to initiate a set of experiments on high-order harmonic generation (HHG) in hollow core waveguides and to verify a higher conversion efficiency of HHG in waveguides compared to classical HHG schemes. High harmonics are in this context electromagnetic waves generated by focusing laser light into a dilute noble gas. The frequency of the thereby generated waves is q t
The aim of this master’s thesis, as suggested by the title, is to study the usage of film in cultural history exhibitions. The subject arouse from queries such as: why are films so often included in cultural history exhibitions? And what do the films provide the visitors with? The thesis sees a distinct difference between the use of film in cultural history museums and the use of film in art museu
Perfluoroktansulfonsyra, PFOS en av människan tillverkad organisk syra, vars väteatomer har blivit utbytta mot fluoratomer och är en nyligen upptäckt förorening som tros finnas i 3,6 miljoner svenskars dricksvatten. Den här kandidatuppsatsen är en litteraturstudie i vilken förekomsten av PFOS i grundvattnet studeras. Det är förmågan att bilda ytbeläggningar som är avvisande mot smuts, fett och vatThe manufacture of products containing PFOS started in the 1950s, and has mainly been used as fire-fighting foam, (Aqueous Film Forming Foam), flooring, textiles, leather impregnation, cleaning and in impregnated paper. This has resulted in a global contamination that is widely spread in the hydrosphere, biosphere and the atmosphere; due to long and intensive use without any regulations. PFOS is a
Context. Intensity interferometry was invented and used by R.Hanbury Brown and R.Q.Twiss in the 1960's to measure stellar angular diameters. Its main advantage over conventional interferometry is that it enables very long baselines and is insensitive to poor seeing. However, because it requires very large light collectors, it was never pursued further. The Cherenkov Telescope Array (CTA) is a
Syftet med denna uppsats är att analysera kommunernas lagefterlevnad och om den varierar beroende av vilken politisk majoritet som styr kommunen. Konkret kommer det att ske genom att vi analyserar i vilken utsträckning kommunerna implementerat lagen om kommunala bostadsaktiebolagen, manifesterat som större utdelningar och högre vinstmarginaler. Vi kommer att sätta detta i relation till om kommunerThe purpose of this thesis is to analyze the level of law-abidingness of the Swedish municipalities and if this level differs with political majority. We do this by looking at by which extent they have implemented the law concerning these housing companies. By examining trends on their level of profit margins and dividends. Lastly we put this in relation to whether the municipalities adapt to the
Abstract A radar study was performed to compare flight parameters between sparrowhawks and common buzzards during autumn migration at the Falsterbo peninsula, Sweden. Common buzzards had higher flight altitudes and were more selective for wind, yet their air - and cross-country speeds were lower than those of sparrowhawks. Furthermore, common buzzards had higher glide ratio, but lower airspeed w
This thesis addresses many issues surrounding the simple question: why have trams? With city populations exponentially growing alongside concerns over the environment and the economy, tramways have become a resurging form of sustainable transportation for municipalities. Once an endangered transportation mode, torn up and scrapped to make room for the age of cars, tramways are phoenix artifacts of
Damages, caused by moisture and mould, in cold attics have increased in Sweden during the last decades. The main reasons are thicker thermal insulation between the living space and the attic and lack of the heat and ventilation effects from a warm chimney. Cold attics are ventilated to avoid that heat leakage from the living space heats up the outer roof with snow melting and icicles as result. Wi
The reporting obligations under the TRIPS Agreement should provide a basis for discovering how the developed countries provide incentives to enterprises and institutions in their territories for the purpose of promoting and encouraging technology transfer and if these activities lead to concrete and helpful best industry practices. The obligations must be seen in their context. Other international
Recent advances in artificial intelligence and deep machine learning have created a step change in how to measure human development indicators, in particular asset-based poverty. The combination of satellite imagery and deep machine learning now has the capability to estimate some types of poverty at a level close to what is achieved with traditional household surveys. An increasingly important is
Traditionally, food safety knowledge has been seen as a factor in improving food safety behaviour. However, the relationship between knowledge and behavior is complex. The aim of the present study was to investigate self-reported data from 408 university students regarding food safety background, knowledge, attitudes, and behaviour using Structural Equation Model (SEM) to examine the influence of
We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically monitored by the TESS space mission in Sector 10. We obtain and model the stellar spectrum and find an object slightly smaller than the Sun, and somewhat older, but with a similar metallicity. Two planet candidates were found in the light curve t
Some theories of planet formation and evolution predict that intermediate-mass stars hostmore hot Jupiters than Sun-like stars, others reach the conclusion that such objects are very rare. By determining the frequencies of those planets we can test those theories. Based on the analysis of Kepler light curves it has been suggested that about 8 per cent of the intermediate-mass stars could have a cl
Measurements of the pT-dependent flow vector fluctuations in Pb-Pb collisions at sNN=5.02TeV using azimuthal correlations with the ALICE experiment at the Large Hadron Collider are presented. A four-particle correlation approach [ALICE Collaboration, Phys. Rev. C 107, L051901 (2023)2469-998510.1103/PhysRevC.107.L051901] is used to quantify the effects of flow angle and magnitude fluctuations separ
Vapor–solid–solid (VSS) growth of III-V semiconductor nanowires (NWs) has long been considered an alternative for the vapor–liquid–solid (VLS) growth mode, with the potential to avoid the incorporation of deep-level impurities into semiconductors and to form compositionally abrupt interfaces. Most research however indicates that VSS growth has a much lower growth rate than observed in the VLS grow
Single motherhood has long been a feature of European family systems, but its meaning and determinants have changed substantially over time. Using longitudinal individual-level data from the Scanian Economic and Demographic Database (SEDD), covering southern Sweden between 1905 and 2015, we examine the changing demography of single motherhood from a long-term life course perspective. We analyze ho
Recent land-use changes have led to a significant loss of natural wetlands worldwide resulting in increased amounts of organic and inorganic compounds reaching lakes and coastal areas. In turn, this has led to an increased algal growth, and subsequently the risk of algal blooms and deteriorated water quality. The capacity of wetlands to retain nutrients is well-known, suggesting that constructed w
