Populärvetenskaplig sammanfattning: Frågan om jordens ålder fick sitt svar först vid 1900-talets början, då upptäckten gjordes att uran sönderfaller till bly med bestämd hastighet. Genom att mäta blyisotoper i uranhaltiga mineral kunde man räkna baklänges och se hur lång tid som krävts för att den uppmätta mängden bly skulle bildas. Samma typ av beräkningar gjorda på mineralet zirkon (ZrSiO2) är iZircon crystals from mafic intrusive rocks and surrounding gneisses were studied using back-scattered electron and cathodoluminescence imaging and laser ablation ICPMS. The rocks are exposed on the island of Norra Horten northwest of Varberg off the western coast of Sweden. The intrusion is mainly made up of amphibolite and metadiorite. Most zircons in the mafic rocks have prismatic external morph

This master's thesis sets out to explore information literacy in a contextualized learning environment with emphasis on students at a vocationally oriented program in the Swedish upper secondary school. The concept of information literacy is widely discussed and furthermore a common subject for research within the field of Library and Information Science. Information literacy can be described

Aims. The present study was conducted to determine the optical extinction curve for Cerro Paranal under typical clear-sky observing conditions, with the purpose of providing the community with a function to be used to correct the observed spectra, with an accuracy of 0.01 mag airmass(-1). Additionally, this work was meant to analyze the variability of the various components, to derive the main atm

Dasatinib, a broad-spectrum tyrosine kinase inhibitor (TKI), predominantly targets BCR-ABL and SRC oncoproteins and also inhibits off-target kinases, which may result in unexpected drug responses. We identified 22 patients with marked lymphoproliferation in blood while on dasatinib therapy. Clonality and immunophenotype were analyzed and related clinical information was collected. An abrupt lympho

This project started out as a test, and a request, an invitation to participate in a highly singular architectural project. Located in the western harbour of Malmö, the OHBOY! bike hotel belongs to an ambitious and ground-breaking approach at redefining the way we design cities and map- out our priorities, emphasizing mobility and making an active effort at minimizing our impact on the city’s tra

Under 1900-talets första kvartal arbetade lagstiftaren med att införa nya och revidera gamla lagar på familjerättens område. Många av lagarna hade sett mycket lite förändring sedan deras införande i och med 1734 års lag. År 1915 förändrade man begreppet trolovning och dess innebörd blev mycket mer vidsträckt än vad det tidigare hade varit. Det blev nu ett helt formlöst avtal som ansågs ingånget såDuring the first quarter of the 20th century, the legislator worked to introduce new laws and revise old ones concerning family law, many of which had seen very little change since their introduction in the law of 1734. In 1915, the concept of betrothal changed and its meaning became much more extensive than it used to be. It was now a completely formless agreement that was concluded as soon as th

This research is exploring policy coherence of energy, climate, and biodiversity policies on the case study of new hydropower developments in the Republic of Slovenia. A qualitative case-study approach utilising policy document analysis and interviews was chosen to conduct this research. This analysis revealed that policy objectives were coherent within policy sectors but not across policy sectors

Popular Science Summary Konsten att kunna ta bort ett syre Alla celler har DNA, som måste repareras och kopieras för att livet ska fortgå. För att kunna göra detta måste det finnas byggstenar. En av alla processer som ser till att alla delar finns i rätt mängd innefattar bara ett protein. Ett protein som får instruktioner från många håll för att gå igenom en komplicerad process som tillverkar dessThe protein ribonucleotide reductase catalyses the de novo synthesis of deoxyribonucleotides (dNTPs) from ribonucleotides (NTPs), using radical chemistry. It is under strict allosteric regulation, partly from the dNTPs it synthesises that regulate what substrate should be synthesised, but also from dATP/ATP, which regulates overall activity. It is a protein that is found in almost every living org

Sammanfattning I det här examensarbetet utreds rättsläget för en arbetstagares lojalitetsplikt och yttrandefrihet i sociala medier. Facebook, Twitter och bloggar hör till de sociala medier som under de senaste åren har visat på en drastisk ökning av användare. De sociala medierna har fått stor genomslagskraft och används dagligen för att rapportera och uppdatera omgivningen om såväl privata som saSummary In this thesis, the legal situation of a worker's duty of loyalty and freedom of speech in social media will be investigated. Facebook, Twitter and blogs are examples of social media’s that have shown a dramatic increase in users during the past years. Social media has a major impact on today’s society and are used by people daily to report and update others about different thoughts an

Background: The 10-m walk test (10MWT) is a widely used measure of gait speed in Parkinson’s disease (PD). However, it is unclear if different standardizations of its conduct impact test results. Aim of the study: We examined the clinical significance of two aspects of the standardization of the 10MWT in mild PD: static vs. dynamic start, and a single vs. repeated trials. Implications for fall pre

Magnetic resonance imaging (MRI) permits the visualization of anatomical structures not appreciated by conventional radiographic imaging, and may assess inflammatory disease and its progression with greater sensitivity than conventional radiography. In this study of 30 patients with early rheumatoid arthritis (RA), which could be considered as a pilot study because of the relatively small number o

BACKGROUND: Cerebral endothelial dysfunction occurs in a spectrum of neurodegenerative diseases. Whether biomarkers of microvascular endothelial dysfunction can predict dementia is largely unknown. We explored the longitudinal association of midregional pro-atrial natriuretic peptide (MR-proANP), C-terminal endothelin-1 (CT-proET-1) and midregional proadrenomedullin (MR-proADM) with dementia and s

With peroral levodopa treatment, a majority of patients develop motor fluctuations and dyskinesia already within a few years of therapy. Device-aided Parkinson (PD) therapies refer to deep brain stimulation (DBS), levodopa-carbidopa intestinal gel infusion (LCIG), and subcutaneous infusion of the dopamine agonist apomorphine and represent effective strategies counteracting motor fluctuations and d

Low-energy electron diffraction, scanning tunneling microscopy, and photoelectron spectroscopy results from the submonolayer Sm- and Yb-induced surface structures are presented. Several similar metal-induced surface reconstructions are found to exist for Yb and Sm on Si(111) for low submonolayer coverages: 3×2, 5×1, and 7×1. At higher submonolayer coverage, Yb induces a 2×1 reconstruction while Sm

The purpose of this study is to identify and structure challenges of measuring performance of the Sales and Operations Planning (S&OP) process. A multiple case study methodology was applied. Qualitative data was collected via 22 structured interviews with managers from six case companies in various industries. A process oriented framework was proposed by structuring the challenges based on two

BACKGROUND AND PURPOSE: Genome-wide association (GWA) studies have identified a few risk loci for ischaemic stroke, but these variants explain only a small part of the genetic contribution to the disease. Coding variants associated with amino acid substitutions or premature termination of protein synthesis could have a large effect on disease risk. We performed an exome array analysis for ischaemi

ABINIT is a package whose main program allows one to find the total energy, charge density, electronic structure and many other properties of systems made of electrons and nuclei, (molecules and periodic solids) within Density Functional Theory (DFT), Many-Body Perturbation Theory (GW approximation and Bethe-Salpeter equation) and Dynamical Mean Field Theory (DMFT). ABINIT also allows to optimize

Synchrotron radiation X-ray tomographic microscopy (SRXTM) was used to virtually dissect and peel the shields off of the microscopic, bivalved phosphatocopine crustaceans in the Cambrian ‘Orsten’ type of preservation of Sweden. Doing so opened up for an array of concealed internal structures to be observed in a fully enclosed specimen of Hesslandona ventrospinata and a semi-enclosed specimen of He

A fully integrated remote antenna unit (RAU) intended for fiber-fed distributed multiple-input multiple-output systems is presented. The circuit is designed for narrowband (60 MHz) time-division duplex systems, where an IF over fiber approach is chosen to facilitate the use of low-cost optical components and integrated photodetectors. A novel antenna switch control scheme is introduced, which enab
