Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products. The purpose of this resea
Popular Abstract in Swedish Bestrålning av allmänheten från radioaktivt cesium efter Tjernobylolyckan. Fältstudier i ett högkontaminerat område i Bryanskregionen i Ryssland. Olyckan i kärnkraftverket i Tjernobyl i Ukraina 1986 orsakade att stora delar av Europa kontaminerades med radioaktiva ämnen, varav 137Cs är det som fortfarande finns kvar pga sin långa halveringstid (30.2 år). BryanskområdetFrom 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0.9-2.7 MBq m-2. Yearly
Abstract Question: Can satellite data be related to fine-scale species diversity and does the integrated use of field and satellite data provide information that can be used in the estimation of fine-scale species diversity in semi-natural grassland sites? Location: The Baltic Island of Oland (Sweden). Methods: Field work including the on-site description of 62 semi-natural grassland sites (repres
Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed
Looking back over 30 years of Swedish health care, professor Saltman examines structural changes in the Swedish health care sector. This is a very welcome contribution to the literature, and it makes good sense – institutional change is often a slow process, and it may take considerable time before the effects can be fully appreciated. Saltman’s paper provides a useful analytical overview of thre
Long-term records of environmental history at decadal to millennial time-scales enable an assessment of ecosystem variability and responses to past anthropogenic disturbances and are fundamental for the development of environmental management strategies. This study examines the local variability of land-use history in the South Swedish Uplands over the last 200 years based on pollen records from t
Background: Staff who plan and organize day center activities may need to observe the attendees’ performance and progression. This led us to develop a tool for that purpose, termed General Occupational Engagement in people with Severe mental illness (GOES). The aim was to investigate its psychometric properties in terms of factor structure, internal consistency, corrected item-total correlations (
Rheumatoid Arthritis (RA) is a chronic, inflammatory, and systemic disease of unknown aetiology that affects0.5‒1.0% of the population in Europe, more women than men. Pain, physical disability, fatigue, and sleepdisturbances are some of the most pronounced symptoms in patients with a more severe disease or with a longerdisease duration, resulting in activity limitations that affect quality of lifeRheumatoid Arthritis (RA) is a chronic, inflammatory, and systemic disease of unknown aetiology that affects 0.5‒1.0% of the population in Europe, more women than men.

Background. Exposure to lead (Pb) in environmental and occupational settings continues to be a serious public health problem and may pose an elevated risk of genetic damage. Objectives. The aim of this study was to assess the level of oxidative stress and DNA damage in subjects occupationally exposed to lead. Material and methods. We studied a population of 78 male workers exposed to lead in a lea
Objective: We aimed to study the association between neighborhood socioeconomic status at the age of 40 years and risk of ischemic stroke before the age of 50 years. Methods: All individuals in Sweden were included if their 40th birthday occurred between 1998 and 2010. National registers were used to categorize neighborhood socioeconomic status into high, middle, and low and to retrieve informatio
Recent climate warming has altered plant phenology at northern European latitudes, but conclusions regarding the spatial patterns of phenological change and relationships with climate are still challenging as quantitative estimates are strongly diverging. To generate consistent estimates of broad-scale spatially continuous spring plant phen
Popular Abstract in Swedish Eld har fascinerat människan i alla tider. Att sitta och värma sig vid en lägereld, sjunga sånger eller bara titta på hur elden rör sig är något de flesta har upplevt. Hur många har egentligen funderat på var värmen kommer ifrån, hur den gula färgen uppstår eller vad eld egentligen består av? Några av frågorna finns det nu svar på, men fortfarande finns det mycket att uThe work presented in the thesis covers the use of laser-induced fluorescence (LIF) and photofragmentation laser-induced fluorescence (PFLIF) with short laser pulses to determine species concentrations in different combustion environments. To attain quantitative species concentrations using LIF investigations of the influence of collisional quenching on the fluorescence signal strength is of vital
The Benguela Upwelling System (BUS), located between 30 and 20°S, is one of the fundamental high-productivity systems of the world ocean. The BUS has previously been studied in terms of primary productivity and ecology over glacial-interglacial timescales; however, the response and coupling with the benthic environment have received little attention. Here, for the first time, we present a high-res
The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes. It has resulted in higher transition frequencies and red
For model-based quantitative reconstructions of past vegetation cover on the scale of landscapes, pollen productivity estimates (PPEs) are key input parameters. In this study, we employed a random sampling strategy to collect moss polsters at 20 sites in Changbai Mountain, northeastern China. A detailed vegetation survey within 1000-m radius around each sampling point was carried out and digitized
Sammanfattning Uppsatsen behandlar det adopterade barnets rätt till kännedom om sitt ursprung. Frågan har diskuterats vid flertalet tillfällen och är nu aktuell på nytt, då den uppmärksammas i utredningen SOU 2009:61 – Modernare adoptionsregler. I utredningen föreslås en lagstadgad informationsskyldighet för adoptivföräldrar att informera barnet om dess ursprung. Denna bestämmelse skall sakna sankSummary This Graduate Thesis examines the adopted child´s right to knowledge of his or her origin. The biological parentage has been a subject of discussion throughout the history of adoption. In accordance with SOU 2009:61, the Committee has proposed a provision to be introduced requiring a person who has an adopted child, to inform the child of his or her biological origin. The provision is not
Glulam is almost exclusively the chosen material of timber frame structures. Of those, three-hinged (three-pin) portal frames are incomparably the most common type. Being both statically determinate and stable against horizontal forces in its own plane offer both practical (basic constructive details) and economical benefits. The design of the haunch allows for various solutions: it can be curved
Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale
As a country with a high proportion of population and land area in the world, China is in a stage of changing its economic development direction, from the previous extensive economic growth to the intensive economic growth. At the same time, due to the limited total amount of resources and limited environmental bearing capacity on the earth, certain constraints are found in terms of amount and str
Vast amounts of resources extracted through the times are in today’s built environment, with only an estimated 20-30% of building material recycled or reused and the sector accounting for over 35% of the EU’s total waste generation. Buildings are also responsible for 25-40% of all global carbon dioxide emissions. Circular Economy (CE) refers to the better management of resources and waste by closi
