Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ
The radionuclides (210)Po and (210)Pb widely present in the terrestrial environment are the final long-lived radionuclides in the decay of (238)U in the earth's crust. Their presence in the atmosphere is due to the decay of (222)Rn diffusing from the ground. The range of activity concentrations in ground level air for (210)Po is 0.03-0.3 Bq m(-3) and for (210)Pb 0.2-1.5 Bq m(-3). In drinking water
Mycoprotein from the fungi Fusarium Venenatum A3/5 has been used as a meat alternative for a long time but little attention has been paid to the waste it creates. When the fungi is fermenting it uses a lot of water which is sent to the drain after the process is finished. This water contains large quantities of both nutrients and biomass. As circular economy is becoming more important for environm
Introduction: The knowledge of the diffusion coefficient of a solute in neat carbon dioxide (CO2) and CO2 mixed with organic solvents is of importance as it correlates to the efficiency of chromatography and extraction processes. Background: Several studies have been found in literature for diffusion coefficients measurements of different solutes in neat carbon dioxide, but to our knowledge rather
Den 1 juli 2020 infördes ett nytt regelverk gällande rapporteringspliktiga arrangemang i Sverige och i samband med detta infördes även en uppgiftsskyldighet att lämna uppgifter om rapporteringspliktiga arrangemang till Skatteverket. För att ett arrangemang ska vara rapporteringspliktigt ska det vara gränsöverskridande samt innehålla minst ett kännetecken. Ett kännetecken är en egenskap i ett arranOn the July 1, 2020, a new framework of rules regarding reportable arrangements was introduced in Sweden and at the same time a reporting obligation to give information about reportable arrangements to the Swedish Tax Agency (STA) was introduced. For an arrangement to be reportable it must be cross-border and include at least one hallmark. A hallmark is a characteristic in an arrangement which is
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
Klimatet har varit relativt stabilt under den nuvarande interglaciala epoken (Holocen) som inleddes för ungefär 11 700 år sedan. Genom klimatrekonstruktioner från olika geologiska arkiv såsom iskärnor, sjösediment och torvmossar har det ändå påvisats att snabba förändringar i klimatet har inträffat under denna epok. En sådan tidsperiod inträffade för omkring 2800 år sedan och den är intressant ur Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. There are, however, indications for a global extent of the climate change. The climate change coincides with a distinct increas
Northern Fennoscandia belongs to the sub-arctic environment and its forests are mostly composed of mountain birch trees (Betula pubescens ssp. czerepanovii). Outbreaks by autumn moth (Epirrita autumnata) and winter moth (Operophtera brumata) are one of the most important natural disturbance factors in the mountain birch forests, with important implications for future ecosystem functioning. If ther
Today’s market for gas turbines is very competitive and it is important to constantly improve the performance of the engines. It is commonly known that gas turbines have better performance at low ambient temperatures than at high ambient temperatures. One way to counteract the negative influence of a high ambient temperature is to use variable compressor guide vanes. The aim of this thesis is to e
Aim: The aim was to estimate the uncertainty of various factors, influencing the radioiodine uptake (RAIU) at clinical measurements of hyperthyroid patients. Furthermore, to evaluate the estimation of thyroid volume from nuclear medicine scintigraphic images. Another aim was to investigate in what extent these uncertainties may influence the eventual therapeutic radioiodine activity, and thereby t
Importance: The 2023 American College of Rheumatology and American Association of Hip and Knee Surgeons Clinical Practice Guideline concluded that obesity alone should not delay joint replacement. Therefore, a substantially increased utilization of joint replacement among patients with obesity could be expected. However, patients with obesity are at increased risk of revision, posing unique challe
Background: The risk of stroke associated with carotid artery restenosis after stenting or endarterectomy is unclear. We aimed to compare the long-term risk of restenosis after these treatments and to investigate if restenosis causes stroke in a secondary analysis of the International Carotid Stenting Study (ICSS). Methods: ICSS is a parallel-group randomised trial at 50 tertiary care centres in E
The development of tau-PET allows paired helical filament tau pathology to be visualized in vivo. Increased knowledge about conditions affecting the rate of tau accumulation could guide the development of therapies halting the progression of Alzheimer's disease. However, the factors modifying the rate of tau accumulation over time in Alzheimer's disease are still largely unknown. Large-scale longi
This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during epitaxial growth of InAs nanowires were used as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole quantum dots and electron-elect
