A set of single pass full penetration friction stir bead-on-plate and butt welds in HSLA-65 steel were produced using a range of traverse speeds (50 to 500 mm/min) and two tool materials (W-Re and PCBN). Part I described the influence of process and tool parameters on the microstructure in the weld region. This article focuses on the influence of these parameters on residual stress, but the presen
The purpose of this paper was to assess how the EU chemical regulation, REACH, affected the reform of the U.S. Toxic Substances Control Act. It borrows from theories of policy diffusion and of the EU as a regulatory power, which were used to theorize two causal mechanisms potentially leading to convergence between the European and American chemical regulations, tested using a method of process-tra
Northern peatlands have accumulated carbon for thousands of years and currently hold around one third of all soil carbon on earth. Large uncertainties are associated with predictions of how northern peatlands will react to climate change. This is because the cold, wet and anaerobic conditions lead to two opposing forces from a radiative forcing perspective – CO2 sequestration from photosynthesis b
The initiating impetus of this project was a frustration over the en-masse inaction experienced in relation to the climate crisis. Although people are aware of necessary actions few are able to act. This project attempts to understand people’s inability to act whilst looking at ways to counter this apathy through behavioral change. Through research on convenience, human behavior and inaction we a
Kuannersuit Glacier, a valley glacier on Disko Island in west Greenland, experienced a major surge from 1995 to 1998 where the glacier advanced 10.5 km and produced a similar to 65 m thick stacked sequence of debris-rich basal ice and meteoric glacier ice. The aim of this study is to describe the tectonic evolution of large englacial thrusts and the processes of basal ice formation using a multipr
This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and solve the re- sulting nonlinear program using an interior-point algorithm. For this approach, the time to solve the linearized KKT system at each iteration typically dominates the total solution time. In our propo
The terahertz region of the electromagnetic spectrum is an important research area allowing insights into fundamental science such as inter-molecular interactions, and with applications in the environmental, medical and security field. Using femtosecond lasers, it is possible to design compact and efficient terahertz generation schemes, resulting in few-cycle broadband pulses. This master thesis i
Älvar och vattendrag i Västra Sverige utsätts för konstant erosion när ytvattnet från sjöar och mark tappas ut i havet. Den geologiska sammansättningen i älvarna under högsta kustlinjen består av glaciala och postglaciala finkorniga sediment som är avsatta i marin miljö. De känsliga lerlagrens struktur har efter urlakning blivit mer instabila och vid störning kan utlösa skred. Effekten av klimatföRivers and streams in Western Sweden are exposed to constant erosion when surface water from lakes and land discharge into the sea. The geological composition of the rivers under the highest coastline consists of glacial and postglacial fine-grained sediments deposited in marine environments. The leakage of the sensitive clay layers has become more unstable after leaching and, in the event of a di
Background: In soils contaminated by hydrophobic organic compounds, the concentrations are less indicative of potential exposure and distribution than are the associated chemical activities, fugacities and freely dissolved concentrations. The latter can be measured by diffusive sampling into thin layers of polymer, as in, for example, solid phase micro-extraction. Such measurements require equilib
Syftet med denna studie är att fokusera på hur inspiration kan ta sig uttryck i eget, musikaliskt övandeoch framträdande. Denna studie bygger huvudsakligen på intervjuer och syftar till att återspegla tre personers – som alla har olika musikaliska bakgrunder - tankar,insikter och erfarenheter av detta ämne. Tilläggsvis har jag strävat efter att ge läsaren ett omfattande bakgrunds- och teori kapiteWhat is inspiration? – A study in how inspiration can be reflected in one’s own musical practice and performance. The object of this study is to focus on how inspiration can be manifested in one’s musical practice and performance. Based primarily on interviews, this study aims to reflect three persons’ -all of whom have different musical backgrounds - thoughts, insights and experiences of this top
This thesis examines how Corporate Social Responsibility (CSR) can be used as a tool to influence democratization and democratic norms. In a globalized world where companies nowadays can differentiate their production and sale by outsourcing their production in a country where labor is cheaper, followed by higher demands on the transnational companies set by the surroundings, however, resulted in
Först och främst är det här en uppsats om det tvärvetenskapliga studieområdet juridik-och-film, och uppsatsen syftar till att visa varför detta område är relevant och intressant för såväl jurister som filmvetare och en intresserad allmänhet. Filmens samhälleliga roll under de senaste 100 åren kan knappast underskattas, och detta unika medium blir ständigt mer frekvent förekommande i den svenska bFirst and foremost this is an essay on the interdisciplinary studies of law-and-film, which aims to show why this area is relevant and interesting to legal practitioners and scholars as well as to film scholars and the general public. Film's role in society during the past 100 years can hardly be underestimated, and this unique medium has become ever more frequent in the Swedish criminal proc
The proportion of public procurement is nowadays more than substantial; it amounts to all the goods and services that the State, perceived as both: central and local administrations, demands in order to assure the effective and sustainable functioning of the society. Moreover, as the procurement procedures aim at simultaneously achieving best value for money and high standards in non-financial mat
This report details the process and result of developing a mathematical inventory control model to be use by AQ Electric Suzhou. The mathematical model was written in Microsoft Excels inherent programming language Visual Basic and utilizes printouts such as sales history, bill of materials, component data etc. from AQ Electric Suzhous ERP system Monitor to derive a demand history for each componen
Popular Abstract in Swedish I en tid då vi är medvetna om problemen med beroendet av fossila material, både som energi- och råvarukälla, måste vi söka långsiktiga och miljömässigt hållbara lösningar. Katalys kan utgöra ett viktigt bidrag i detta arbete, då det möjliggör reaktioner som annars skulle vara svåra att genomföra på grund av en för hög energibarriär. I takt med den övriga teknologiska ut
Popular Abstract in Swedish Att gifta sig eller att vara med om en olycka är emotionella händelser som skapar våra mest livfulla och detaljerade minnen. Sådana minnen av händelser i tid och rum kallas generellt episodiska minnen. De flesta människor minns till exempel nästan exakt var de var när de hörde talas om terrorattackerna i New York 2001. De flesta av oss har nog redan glömt vad som hände The investigation of memory distortions provides insights into how memory normally works. Adopting a cognitive neuroscience perspective, the present thesis aimed at investigating memory distortions and the neural correlates of processes contributing to successful control of memory interference in healthy participants. All studies employed variations of the modified continuous recognition task. In
