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

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

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

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

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

Vatten är nödvändigt för att den mänskliga kroppen ska fungera. För att vattnet ska kunna transporteras in och ut ur cellerna behöver det komma igenom cellmembranet, vilket det bland annat gör via en särskild klass av proteiner som fungerar som vattenkanaler – akvaporinerna. Akvaporiner finns överallt i vår kropp och är viktiga för många biologiska funktioner såsom metabolism och återfuktning av hAquaporins (AQPs) are a family of transmembrane proteins, mainly mediating water transport over the cell membrane in various parts of the body. The aquaporins AQP3 and AQP7 are both part of the subfamily aquaglyceroporins, which apart from water conduct small non-polar solutes such as glycerol. AQP3 overexpression or malfunction has been connected to skin and lung cancer and potential AQP3 inhibit

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

Hur har föroreningar förändrats över tiden i nordligaste delen av Sverige? Om höga halter tungmetaller finns, vilka kan vara orsakerna till dessa? En resa från södra Skåne till norra Lappland har visat att de flesta metaller i sedimentet från en sjö har minskat på senare år, Hg samt Arsenik har dock ökat. Detta beror troligtvis på minskad användning av fossila bränslen samt gruvdriften i norr.Changes in the accumulation of heavy metals (Cd, Cu, Hg, Fe, Mn, Ni, Pb, Zn), arsenic (As), and selenium (Se) in sediment of pristine lake in northern Sweden were studied by making measurements at different depths in a sediment core. The sediment core was extracted from the deepest part of the lake Sautusjärvi, close to the village Jukkasjärvi. The sediment samples were transported in a cooler to

Distribution patterns of resources and their role in determining species distribution are not only fundamental to the understanding of ecological patterns, but also of practical significance in conservation management. Shorebirds are experiencing precipitous declines globally, especially along the East Asian-Australasian Flyway (EAAF), where the major threats include the loss and degradation of ti

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

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

The regional loess stratigraphy in the Vojvodina region, in the southeastern Carpathian Basin, has often been successfully correlated to the global palaeoclimate. This is a quasi-continuous sedimentary record that provides detailed environmental reconstruction during the last four glacial/interglacial cycles. In this study, we present a standardized loess stratigraphy and illustrate how it correla

INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gend

Carbon pricing, including carbon taxes and emissions trading, has been adopted by different kinds of polities worldwide. Yet, beyond the increasing adoption over time, little is known about what polities–countries as well as sub- and supranational entities–adopt carbon pricing and why. This paper explores patterns of adoption (both implemented policies and those scheduled to be) through cluster an

Hydrological processes in a watershed consist of multiple sub-processes (such as plant growth, evapotranspiration, water yield, and soil–water balance) that have complex interactions. The common practice of calibrating hydrological models against only a single variable (e.g., streamflow) can lead to parameter uncertainty (also known as equifinality), resulting in significant uncertainties in the r
