Popular Abstract in Swedish Inom området diagnostisk nuklearmedicin används radioaktiva läkemedel som ges (administreras) till patienterna i syfte att diagnostisera ett antal olika sjukdomstillstånd. Då man tar fram nya radioaktiva läkemedel för användning inom diagnostisk nuklearmedicin handlar det många gånger om att uppskatta mängden av ett visst upptag av radiofarmakat i olika organ och vävnadAn essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not. It is also important that the biokinetics and dos

Popular Abstract in Swedish Under de senaste decennierna har utbredningen och förekomsten i av många arter av fåglar, växter och insekter knutna till jordbrukslandskap på olika håll i Europa minskat på grund av jordbrukets rationalisering och intensifiering. För att motverka dessa negativa trender måste man ha kännedom om den relativa betydelsen av lokala och regionala ekologiska processer för popDuring the last decades, the distribution and abundance of many European species of birds, plants and insects in agricultural landscapes have declined due to agricultural intensification. To be able to mitigate these declines, it is essential to know the relative importance on local and regional ecological processes on population persistence and patterns of species richness. I have studied the ef

Popular Abstract in Swedish Allteftersom kraven på kvalité och prestanda hos dagens produkter ökar används alltmer avancerade material som en del av modern produktion. Problemet som uppstår är dock att dessa material ställer nya krav på tillverkningsprocessen och då inte minst vid skärande bearbetning. Trots att en betydande mängd forskning redan har publicerats vad gäller skärande bearbetning av As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. Even though a significant amount of research has been published on the machining of these materials knowledge is still limited in several crucial areas. A problem w

A stochastic model based on a probability density function (PDF) was developed for the investigation of different conditions that determine knock in spark ignition (SI) engine, with focus on the turbulent mixing. The model used is based on a two-zone approach, where the burned and unburned gases are described as stochastic reactors. By using a stochastic ensemble to represent the PDF of the scalar

Initial results from the XUV undulator beamline at the 4.5 GeV storage ring DORIS are reported. The beamline consists of three different undulators mounted on a revolver type device and a modified SX-700 plane grating monochromator with a spherical focusing mirror. It covers the spectral range from 50–2000 eV with excellent spectral resolution and high photon flux. In the energy range 400 eV to 1

Vad består materia av? Det är en fundamental fråga som mänskligheten försökt besvara i tusentals år. Vårt svar på den frågan har utvecklats enormt de senaste 200 åren. Atomer, från grekiskans ord för odelbar, bygger upp materian vi ser omkring oss. Det antogs längeatt atomer verkligen var odelbara, men strax innan sekelskiftet år 1900, kom experimentellt bevis från J. J. Thomson, som påvisade attThe papers in this thesis all concern the treatment of colors in perturbative QCD, both in the context of hard scattering cross sections and for parton showers. The complexity of the color structure of QCD increases quickly with the number of external partons. One way of tackling this issue is by using an orthogonal, group theory based, type of bases, called multiplet bases. This is the topic of p

Owing to an increasing shortage of donor organs, the majority of patients with end-stage kidney disease remains reliant on extracorporeal hemodialysis (HD) in order to counter the lifelong complications of a failing kidney. While HD remains a life-saving option for these patients, mounting evidence suggests that it also fuels a vicious cycle of thromboinflammation that can increase the risk of car

Matagorda Peninsula and Sargent Beach, Texas, USA, have experienced some of the highest rates of erosion along the Texas coast. In order to increase protection from tropical events and slow beach habitat erosion, several structural alternatives were studied. These alternatives were modeled with GenCade, a newly developed 1D shoreline change and sand transport model. GenCade was calibrated and vali

Development of single-molecule localization microscopy techniques has allowed nanometre scale localization accuracy inside cells, permitting the resolution of ultra-fine cell structure and the elucidation of crucial molecular mechanisms. Application of these methodologies to understanding processes underlying DNA replication and repair has been limited to defined in vitro biochemical analysis and

A combined measurement and Monte-Carlo simulation study was carried out in order to characterize the particle self-shielding effect of B4C grains in neutron shielding concrete. Several batches of a specialized neutron shielding concrete, with varying B4C grain sizes, were exposed to a 2 Å neutron beam at the R2D2 test beamline at the Institute for Energy Technology located in Kjeller, Norway. The

Previous research has established that when engaged in episodic memory retrieval, people frequently look at locations associated with the sought-after memory trace, even if those locations no longer contain any information. While it has been further demonstrated that gaze positions showing compatibility between encoding and retrieval increase the likelihood of successful remembering (Johansson &amPrevious research has established that when engaged in episodic memory retrieval, people frequently look at locations associated with the sought-after memory trace, even if those locations no longer contain any information.

Regional climate and energy planning in Sweden has long been fairly weak. Starting in 2008, however, the regional administrative level was strengthened, when the County Administrative Boards (CABs) were commissioned to develop regional climate and energy strategies. Coordinating and involving various stakeholders in the strategy work was essential to the assignment. The process of developing these

The recent surge in publications on the history of knowledge may obscure the fact that there are several parallel understandings of what the field is. In this article, I discern five major historiographical directions in contemporary scholarship regarding the history of knowledge. The analytical framework that has so far attracted the most attention is the circulation of knowledge. As productive a

Bostäder står för ca 23% av all energianvändning i Sverige. Om målet netto-nollkoldioxidutsläpp 2045 ska nås är det därför troligt att energibesparande åtgärderför bostäder kommer behövas. Många av de befintliga byggnaderna är runt 50 åreller äldre och är således i behov av modernisering. Samtidigt ökarurbaniseringstakten, därför finns det och kommer även framöver finnas behov avfler bostäder. EneIn Sweden, housing accounts for about 23% of all energy consumption. Sweden wants to reach net zero carbon emissions by 2045; as such, it is likely that energy-saving measures for housing will be needed. Many existing buildings have been in operation for 50 years or more and are therefore in need of modernisation. At the same time, the population is increasing and so is the rate of urbanisation, w

MAX IV is presently under construction at Lund, Sweden, and the first beam for the production of synchrotron radiation is expected to circulate in 2016. The whole set of 3 GeV ring beam pipes is coated with Ti-Zr-V Non Evaporable Getter (NEG) thin film in order to fulfil the average pressure requirement of 1×10-9 mbar, despite the compact magnet layout and the large aspect ratio of the vacuum cham

Metal-halide perovskite semiconductors are certainly one of the hottest topic in solar energy conversion. Optimization of both the absorber material and device architecture has led to an astoundingly rapid increase in the reported device efficiencies. Initially developed in the context of dye-sensitized solar cell research, metal-halide perovskite devices now reach efficiency values and hence need

Two observations serve as starting points for this paper. First, conventional risk assessment techniques provide sophisticated ways to identify and estimate hazards, but eschew the fact that there is no risk unless something of value is considered to be at stake. Second, what managers consider as being of value follows from how they organize their managerial practice. Based on these observations,

Environmental research infrastructures (RIs) support their respective research communities by integrating large-scale sensor/observation networks with data curation services, analytical tools and common operational policies. These RIs are developed as pillars of intra-and interdisciplinary research, however comprehension of the complex, pathologically interconnected aspects of the Earth's ecosyste
