The concept of OptimalTempered Asphalt, OTA, stands for the best temperature all aspects considered for the bitumen and the manufacturing process as well as the end-product. This is achieved in various ways using additives, choice of manufacturing procedure and changing mixture of asphalt. This bachelor thesis is a study of the effects the additive Sasobit has on bitumen and asphalt from an OTA pe
Popular Abstract in Swedish Glas kan användas för retrospektiva radon mätningar på grund av radondöttrars förmåga att implantera i glasets översta skikt. Mängden implanterad aktivitet blir lätt påverkad av en rad olika faktorer i den omgivande luften. Experimentella metoder har därför utvecklats för att bestämma djupfördelningen av alfarekyl-implanterat 210Po i glas. Detta göres genom gradvis etsnGlass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo
Purpose/Objective(s): Over 30% of advanced prostate cancers harbor a predominance of neuroendocrine prostate cancer (NEPC) differentiation. Fluorodeoxyglucose (FDG) positron emission tomography (PET) has numerous limitations in prostate adenocarcinoma (PCa-adeno), however there is no data that exists outside of isolated single person case reports to assess the utility of PET to restage and monitor
National greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change (IPCC) methodological guidance using activity data, emission factors and facility-level measurements. For some sources, the outputs from these calculations are very uncertain. Invers
Piercing the corporate veil is the practice of disregarding the limited liability characteristic of a corporation in order to make its shareholders, either individuals or parent corporations, answer for the corporation's liabilities. In determining whether to apply corporate veil piercing, courts in the United States commonly employ the instrumentality theory, as well as the alter ego and iden
The purpose of this Master Thesis was to design an automatic separator, a machine that would separate organic from non-organic waste through a mechanical process. The use of a mechanical process was one of the target specifications given by WTM AB, the company that initiated the project. WTM is a small machine design company located in Ängelholm, Sweden, who designs machines for different kind of
Context. In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances for large samples of Galactic stars, complementing Gaia astrometry. Among those surveys, the Gaia-ESO Public Spectroscopic Survey, the only one performed on a 8m class telescope, was designed to target 100 000 st
Every living cell is surrounded by a cell membrane that is made up of amphipathicphospholipids, separating the aqueous solutions inside and outside the cell with ahydrophobic barrier. This compartmentalization is a prerequisite for life, but so arethe many molecules that are floating in the membrane, altering its properties andconnecting the inside with the outside. An important group are the tran
Popular Abstract in Swedish Syftet med denna undersökning är att undersöka på vilka sätt bönder kunde göra motstånd och protestera mot överheten under de avslutande decennierna av nordisk senmedeltid, åren 1490-1525, som också utgjorde Kalmarunionens slutskede. Undersökningen består av en komparation mellan det danska Skåne och det svenska Småland, och utförs i tre steg. Först görs en genomgång öv"They defended their Right: late medieval Peasant Resistance in Scania and Småland." The aim of this thesis is to explore in what ways peasants could resist and protest against authorities during the final decades of the Nordic late middle ages, the years 1490-1525. It consists of a comparison between the Danish province of (Scania) Skåne and the Swedish province of Småland. The study is performe
Some 4 billion years ago, nature began the experiment that led to you, that bird on the branch, that branch, and everything else which is alive that you see around you. The generating process of all this splendid life is, of course, evolution. Evolution works not only on the macroscopic scale (think eyes, muscles, wings) but also on the molecular scale (think molecular antennas, nanoscale muscles,The sequence diversity of protein families is a result of the biophysical selection pressures that shaped their evolutionary history. Among the dominant pressures is selection for protein thermostability, which in itself is an attractive target in protein engineering because of its importance for various biopharmaceutical properties, the performance of industrial enzymes, and the ability to design
This thesis deals with the development and application of new estimation approaches based on factor analysis for estimation and inference in dynamic panel data models with fixed-effects. A new factor analytical method (FA) for the estimation of fixed-effects dynamic panel data models is proposed in Bai ("Fixed-Effects Dynamic Panel Models, A Factor Analytical Method". Econometrica 81, 285-314, 201
BACKGROUND: Follow-up with computed tomographic angiography is recommended after endovascular aneurysm repair, exposing patients to significant levels of radiation and iodine contrast medium. Dual-energy computed tomography allows virtual noncontrast (VNC) images to be reconstructed from contrast-enhanced images using a software algorithm. If the VNC images are a good-enough approximation of true
Peanut (Arachishypogaea L.) is one of the most important oil crops worldwide, and its yet increasing market demand may be met by genetic improvement of yield related traits, which may be facilitated by a good understanding of the underlying genetic base of these traits. Here, we have carried out a genome-wide association study (GWAS) with the aim to identify genomic regions and the candidate genes
Objective: To assess the long-term results of elective abdominal aortic aneurysm (AAA) repair with a single stent graft system. Methods: Patients undergoing elective, infrarenal endovascular aneurysm repair (EVAR) with a single-stent graft system between 1998 and 2012 were analyzed retrospectively registering pre-, intra-, and postoperative data. All imaging was reviewed. Data are presented as med
The dynamical stability of tightly packed exoplanetary systems remains poorly understood. While a sharp stability boundary exists for a two-planet system, numerical simulations of three-planet systems and higher show that they can experience instability on timescales up to billions of years. Moreover, an exponential trend between the planet orbital separation measured in units of Hill radii and th
Breast tomosynthesis (BT) is an X-ray imaging technique recently introduced as an alternative or complement to standard digital mammography (DM) in breast imaging and breast cancer screening. In BT, a set of projection images is acquired over a limited angular range and reconstructed into a volume of slice images. The method includes many possible combinations of acquisition parameters that have t
Background: Previous research shows that many cancer-bereaved youths report unresolved grief several years after the death of a parent. Grief work hypothesis suggests that, in order to heal, the bereaved needs to process the pain of grief in some way. This study explored acute grief experiences and reactions in the first 6 months post-loss among cancer-bereaved teenagers. We further explored long-
What does a sustainability project look like in the 21st century? Not the glossy version, but the naked truth? Tired of manicured, over-theorised accounts of the ‘musts’ and ‘shoulds’ of sustainability transitions, we got to the bottom of things; actually, to the very bottom of the project hierarchy: the individual. Our point of departure is that projects are nothing but temporarily interconnected
