The overall aim of this thesis was to describe parents’ expectations, experiences and reactions to a routine ultrasound examination during the second trimester of pregnancy and to develop, test and use a questionnaire. The aim was also to conceptualize the parents’ experiences and ways of handling the situation when the diagnosis was a non-viable fetus. The data for this thesis was collected bet
Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. Nowadays, the cement industry produces cements with increasing amounts of supplementary cementitious materials (SCMs) to
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
Most modern ultrafast lasers are based on mode-locked fiber or solid-state lasers and operate around the near infrared part of the electromagnetic spectrum. The widely spread CPA based Titanium Sapphire lasers can emit pulses centred around 800nm with durations down to 20 fs. However, for many ultrafast experiments light at different centre frequencies are required. In order to obtain other centre
Traditionellt anses vulkanoklastiska interbeds ha dålig reservoarpotential på grund av de vulkaniska komponenterna, som lätt kan omvandlas till olika lermineral. Publicerade arbeten från interbasaltiska sedimentära avlagringar i Faroe-Shetlands Basin tyder dock på annat. Denna studie syftar därför till att utvärdera porositets- och permeabilitetsegenskaper hos vulkanoklastiska interbeds från FaroeTraditionally, volcaniclastic interbeds have been considered to have poor reservoir potential due to their volcanic components readily altering to various clay minerals, but published discoveries within lava successions in the Faroe-Shetland Basin may challenge this dogma. This study therefore, evaluates porosities and permeabilities for volcaniclastic interbeds from the Faroe Islands Basalt Group
Abstract: The zooplankton community of The Area of Multiple Use Hawaii (AUMH), South Pacific Coast of Guatemala mangrove channel ecosystem was studied in the dry season between February and March 2011. Zooplankton samples were taken during two lunar cycles, four tidal cycles (flood, high water (HW), ebb, low water (LW)), at four different sites. For each sampling occasion, salinity, pH, dissolved
Popular science summary: New approaches for treating lakes with ammonia pollution Extract of Yucca shidigera, a desert plant, has been used in aquaculture to control ammonia in the water. Microalgae has been proved effective in removing ammonia and phosphorous from wastewater of agriculture and aquaculture. Therefore, it is possible that they could remove ammonia from lakes. Hence, several fish t
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
Air sampling and biological sampling have been performed to examine the exposure to nicotine in the Nicorette patch and Nicorette gum production at Pfizer Health AB in Helsingborg, Sweden. For this purpose stationary and personal sampling equipment have been used. At the Nicorette patch production, XAD-2 tubes were used to sample nicotine vapor and at the Nicorette gum production Teflon filters we
Uppsatsen behandlar selektiv distribution av luxuösa produkter samt hur marknadsrättsliga regler påverkar möjligheten att upprätthålla sådana system. Lyxprodukter definieras i rättspraxis som högkvalitativa produkter med ett relativt högt pris som marknadsförs under prestigefyllda varumärken. Eftersom karaktären av lyx utgör den främsta konkurrensfördelen vid distribution av denna typ av produkter
Uppsatsen behandlar budpliktsinstitutet i Sverige samt i några andra utvalda länder. Fokus ligger på vilka subjekt som kan drabbas av sanktion, samt vilka typer av sanktioner som finns att tillgå vid ett brott mot sagda budplikt. Institutet har kommit att bli ett av de mer omdiskuterade reglerna på värdepappersmarknaden då det råder osäkerhet om huruvida regeln verkligen passar det svenska företag
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
In Bhutan, post-harvest losses are a significant challenge for many small scale farmers, especially in rural areas. Since these losses impact the ability to preserve foods during the peak harvesting seasons, this has a wide range of consequences, both for the farmers themselves and for the country as a whole. It contributes to food insecurity, economic uncertainty and the nutritional deficiencies
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
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
The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”. Implanted bioele
Recent studies on Alzheimer's disease (AD) suggest that tau proteins spread through the brain following neuronal connections. Several mechanisms could be involved in this process: spreading between brain regions that interact strongly (functional connectivity); through the pattern of anatomical connections (structural connectivity); or simple diffusion. Using magnetoencephalography (MEG), we inves
Background: Randomized trials have demonstrated that early anticoagulation after acute atrial fibrillation-associated ischemic stroke is safe and non-inferior to delayed initiation. Whether anticoagulation should be delayed in people with larger infarcts is uncertain. Aims: To investigate whether ischemic stroke infarct volume, measured precisely by segmentation, modifies the treatment effect of e
