Detta arbetet har hanterat sex olika borrkärnor från den Prekambriska berggrunden i Ohio, USA. Denna berggrund är täckt med 800 – 5000 meter av Paleozoiska avlagringar och på grund av detta vet vi väldigt lite om den. Arbetet har gått ut på att karakterisera och datera dessa bergarter samt att via isotop analyser av syre och hafnium ta reda på bergarternas sammansättning och evolution. BorrkärnoThe Grenville orogen forms a major, continental scale, Mesoproterozoic orogenic belt along the present day eastern North American continent, from Labrador in the north to Mexico in the south. It is, however, mainly exposed in the northeastern parts of North America. Most of the orogen forms a basement to thick piles of Phanerozoic sedimentary rocks, and the geological evolution of the extensive co

Today there are various load bearing systems to choose from, concrete, steel, timber, or a combination of these. What determines the choice is usually the economy, which depends on the solutions in the different load bearing systems that will be made. Many of these choices are made based on previous projects and previous experience but do not always lead to the optimal solution. It is important to

In online auctions bidding frequency tends to increase towards the last minutes of the auction. This thesis investigates why bidders might choose to engage in last minute bidding, sniping, in Tradera auctions (Tradera is a Swedish subsidiary of eBay). Tradera uses a hard-close rule and a second-price rule. In hard-close auctions the dead-line occurs at a specific time, after which new bids are not

This thesis was done in collaboration with the department of Food Technology at LTH, Aventure AB, and Arwa Foodtech AB. The aim of the project was to develop the base for a baobab based, spoonable protein snack, comparable to quarg but free from ingredients of animal origin. At the time of writing, one of the biggest if not the biggest trend in the food industry is the replacement of animal-source

The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. Paper I analyses the performance degradation of d

Popular Abstract in Swedish Under sin livstid har Jorden genomlevt upprepade naturliga klimatförändringar. Genom att undersöka dessa klimatförändringar över tid och rum så kan vi öka vår förståelse för underliggande dynamik och mekanismer och därmed bättre förstå klimatsystemet. Två grundläggande förutsättningar för sådana undersökningar är trovärdiga rekonstruktioner av tidigare variationer i styThroughout its history Earth experienced a variety of natural climate changes. By investigating their spatial and temporal evolution we can increase the understanding of the mechanisms and dynamics underlying natural climate change and improve our general comprehension of the climate system. Prerequisites of these investigations are reliable reconstructions of past forcing variations as well as so

Popular Abstract in Swedish Dagens industriella system är inte långsiktigt hållbara. För detta behövs bland annat fundamentala förändringar av hur samhällets resurser används. Detta gäller den totala volymen som förbrukas men också vilka ämnen som sätts i omlopp i samhället. Därutöver behövs ett mer rättvist utnyttjande av dessa resurser. Industriell ekologi är den vetenskap som studerar de förändToday's industrial systems are regarded to have unsustainable characteristics. In order to acquire a more sustainable state, fundamental changes are needed in the qualitative and quantitative aspects of the resource flows associated with such systems. These need to go hand in hand with a more equitable distribution of the benefits and burdens associated with such resource use. The identification a

Background The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age-sex groups, and countries. The GBD can be used to generate summary measures such as disability-adjusted life

Background and aims Symptoms of dizziness and pain are both common complaints and the two symptoms often seem to coincide. When symptoms appear concomitant for sustained periods of time the symptoms might maintain and even exacerbate each other, sometimes leading to psychological distress. In order to evaluate such comorbidity we studied patients referred to a vestibular unit and to a psychiatric

“The stage is a playground, it’s not a serious place where you have to be at your best, ... it should be a playground.” Nir Ben Gal, choreographerDuring my years of study, and later as a performing artist, performance was never discussed conceptually and questions regarding audience interaction and stage fright were seldom raised. Further, musicians suffering from stage fright are most often refer

Aims: Estimation of prognosis in pulmonary arterial hypertension (PAH) has been influenced by that various risk stratification models use different numbers of prognostic parameters, as well as the lack of a comprehensive and time-saving risk assessment calculator. We therefore evaluated the various European Society of Cardiology (ESC)-/European Respiratory Society (ERS)-based three-and four-strata

Background: Practices regarding hospitalisation of children at diagnosis of type 1 diabetes vary both within countries and internationally, and high-quality evidence of best practice is scarce. The objective of this study was to close some of the gaps in evidence by comparing two alternative regimens for children diagnosed with type 1 diabetes: hospital-based care and hospital-based home care (HBH

Den här avhandlingen presenterar nya metoder och tekniker som utvecklats för att undersöka nanotrådars (NT) och NT-enheters egenskaper, och de resultat som erhållits med dessa. Växt och karakterisering av NT har blivit en stor forskningsområde då NT har visat sig förbättra egenskaperna hos många tillämpningar inom halvledarteknologin, såsom transistorer, solceller och lysdioder. Strukturell sammanThis dissertation presents the new methods and techniques developed to investigate the properties of nanowires (NWs) and NW devices and the results obtained using these methods. The growth and characterization of NWs have become a large research field because NWs have been shown to improve the properties of many semiconductor applications such as transistors, solar cells, and light emitting diodes

Background and objectives A randomized trial was conducted in Tuscany, Italy, to evaluate the effectiveness of HPV vaccination for 25 year old (yo) women who attend at the first time cervical cancer screening. The trial also evaluated immune response after vaccination, reductions of cytological abnormalities and the impact of vaccination on screening activity. Study design During 2010–2011, all 25

This dissertation examines the labor market outcomes of a population of natives and immigrants in Sweden from 1968 and until 2001. Previous research has consistently pointed to the importance of an individual’s country of origin, without being able to fully explain why this is the case. The standard approach is to use the country of origin as a way to measure everything occurring prior to migratio

A model is presented that describes the reemergence of parent spruce bark beetles, Ips typographus, based on breeding density and temperature conditions. Laboratory data obtained at one constant temperature provide the distribution of reemergence time and different combinations of threshold temperatures and degreedays (°D) at mean reemergence. Of these combinations, 167.71 °D above 7.5 °C gave the

Background: Stress myocardial perfusion scintigraphy (MPS) is widely regarded as a useful imaging modality for diagnosing patients with suspected ischemic heart disease. Current European guidelines recommend stress study to be performed first since rest study can be omitted if stress study is interpreted as normal. Thus, a rest study should only be performed in patients with equivocal or abnormal

Avhandlingen behandlar den socialistiska respektive den liberala internationella fredsrörelse som agerade under kvartsseklet före första världskrigets utbrott 1914.During the 25 years before the First World War in 1914 two different kinds of peace movements, one bourgeois-liberal and one socialist, were organised to fight militarism and war. The two movements – represented by the International Peace Bureau and the Second International, respectively – grew in size between 1889 and 1914. At the beginning of 1914, IPB organized over 200 peace associations, repr
