Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. När det gäller etappvis spännarmerade betongbroar har dessa förenklingar visat sig ge felaktiga prognoser av de tLong-term effects, such as creep, shrinkage, and steel relaxation, are often difficult to predict for prestressed concrete structures. Creep as a phenomenon is complicated to describe and is therefore simplified in the current building standards, to better accommodate the designer. When dealing with segmentally constructed prestressed concrete bridges, these simplifications have shown to provide i

Outside the box. On archivists' views on objects in municipal archives Historically objects in archives and objects as "documents" have been discussed for a long time. The focus of the discussion has generally been on defining what is a document, and what is not, and later what is in turn an act and thus belongs in the archive, and what does not. An object is generally not defined a

As a global society we are entering an era where land areas and land-based resources are coming to the fore once again for capital accumulation and economic growth, for the first time since the end of the 18th century when Malthus forecasted a contradiction between population growth and agricultural output. That constraint on economic growth, imposed by limited land areas, was overcome by the comb

Solceller – en miljövänlig energikälla? Miljöförstöring i form av växthusgasutsläpp är en gigantisk utmaning som mänskligheten står inför och vi måste agera NU! Solceller innebär en fantastisk möjlighet att utvinna stora mängder “ren” energi från solen. Men hur miljövänliga är egentligen solceller och är det ett effektivt alternativ i Sverige? Varje timme träffas Jorden av tillräckligt mycket eClimate change is one of the greatest environmental challenges at the present time and is currently an issue affecting the entire global population. Alternative renewable energy sources are vital to be able to deal with this challenge. Solar energy is one of the most promising renewable energy sources and is therefore also one of the fastest growing industries in this field. However, solar energy

Islamiska Staten har de senaste fem åren orsakat oerhört mycket smärta och sorg. Krigsförbrytelser, brott mot mänskligheten och folkmord ska ha begåtts i de områden rörelsen kontrollerat i Irak och Syrien. Nu när kalifatets sista fästen besegrats står det internationella samfundet inför en ny utmaning; hur och var ska de ansvariga individerna straffas? Vissa politiker har numera hävdat att en IS-tDuring the past five years, the Islamic State has been responsible for a large amount of pain and suffering. War crimes, crimes against humanity and genocide have been committed in the areas the group controlled in Iraq and Syria. Now as the Kalifate’s last strongholds have been defeated, the international community stands before a new task; how and where shall the individuals responsible be punis

Mangroveskogens ekosystem är ett tropiskt kustsamhälle bebott av organismer anpassade till den stressfulla miljön i tidvattenszonen. Mangroveskogen har på senare år blivit erkänd för de viktiga ekosystemtjänsterna den erbjuder. Trotts detta hotas den av mänskliga aktiviteter, och en tredjedel av världens naturliga mangroveskog uppskattas redan ha gått förlorad. Ansträngningar har gjorts för att beThe mangrove ecosystem is a tropical coastal community inhabited by organisms adapted to the stressful environment of the tidal zone. Mangrove ecosystems has in recent years been noted for the important ecosystem services they offer. Still, they are threatened by anthropogenic activities and it has been estimated that a third of the world’s natural mangrove cover has already been lost. Efforts hav

Shared micro-mobility services are increasingly embraced by cities around the world in recent years. Their benefits over other transportation modes in certain frames encourage traffic/urban planners, public authorities to establish such systems in urban areas. However, planning the placement, size and operation of such beneficial micro-mobility mode is a vital issue that concerns designers. Severa

Since its composition two centuries ago in 1824, Beethoven’s Ninth Symphony (Ode to Joy) has been heralded the world over not only as a great work of art, but also as a symbol of political importance. In Germany, it was lionised as the embodiment of a national spirit, first during the Franco-Prussian war, then as a prize of the Nazi repertoire; in Rhodesia, it became the national anthem of a far-r

Jus cogens norms and obligations erga omnes are concepts within international law that are often used to reinforce legal claims. This thesis aims to assess to what extent invoking these concepts, along with their reinforcing capabilities, is justified in specific cases. In order to achieve this, the thesis first gives an overview of the theoretical debate surrounding the concepts of jus cogens no

Water for Injection (WFI) is a critical utility in pharmaceutical manufacturing, traditionally produced through an energy-intensive distillation process. This thesis investigates the feasibility of a more sustainable alternative, ambient WFI production using membrane-based purification technologies combined with ozonation in the storage and distribution loop. Conducted in collaboration with AstraZ

The growing interdependence and interconnectedness of the global community set the pace and frame for the evolution of foreign policy. Diplomacy formerly being the reserve of international communication has consequently been forced to change and branch out. This essay attempts to view these changes and their context at the example of US foreign policy in Pacific Asia. Both hard power translating i

This thesis challenges the prevailing firm-consumer/customer-centric and dyadic perspective that prevails within the brand equity literature, which is based on a linear, straightforward stimulus-response approach to the creation of brand value. Leaning on the literature on interorganisational relationships, stakeholder theory, market emergence/market driving, and firm internationalisation, which s

Palaeomagnetic data are used to study the configurations of continents during the Proterozoic. Applying stringent reliability criteria, the positions of the continents at 12 times in the 2.45- to 1.00-Ga period have been constructed. The continents lie predominantly in low to intermediate latitudes. The sedimentological indicators of palaeoclimate are generally consistent with the palaeomagnetic l

Background and Purpose-The proportion of immigrants has increased in Sweden markedly during the last decades, as in many other Western countries. Incidence of stroke has increased during this period. However, it is primarily unknown whether incidence of stroke and stroke subtypes in Sweden is related to country of birth. Methods-Incidence of first-ever stroke was followed during 10 years in a coho

What do we gain from labeling certain norms of social organization law? This question provides the backdrop against which this chapter will examine the works of Leon Petrażycki and Eugen Ehrlich, two of the founders of legal sociology who devised concepts of law broader than state law. In the course of this examination we shall also assess the relevance of Petrażycki’s 'intuitive law' and Ehrlich’

Lipolysis is an important metabolic pathway controlling energy homeostasis through degradation of triglycerides stored in lipid droplets and release of fatty acids. Lipid droplets of mammalian cells are coated with one or more members of the PAT protein family, which serve important functions in regulating lipolysis. In this study, we investigate the mechanisms by which PAT family members, perilip
