Passive Houses in Sweden. From Design to Evaluation of Four Demonstration Projects.

Popular Abstract in Swedish Energianvändningen i världen måste minska drastiskt inom en snar framtid för att därmed minska utsläppen av växthusgaser och bromsa klimatförändringarna. Energi och handlande med energikällor har även blivit nationella säkerhetsfrågor. Inom Europeiska Unionen används ungefär 40% av den totala energianvändningen i byggnader, vilket innebär ungefär 36% av det totala koldiThe use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. Passive houses are one way to reduce the energy use in buildings and at the same time keep a good indoor comfort. Th

Mineral element contents in drinking water - aspects on quality and potential links to human health

Popular Abstract in Swedish Mineraler fås från både fast och flytande föda. De senaste årtiondena har bordsvattenkonsumtionen ökat, och vattnets kemiska innehåll har alltmer kommit i fokus. Studier visar dessutom att grönsakers mineralinnehåll har minskat, vilket ökar betydelsen av mineralintag från annat håll. Den här doktorsavhandlingen omfattar fyra olika studier. I den första studien undersökMineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. This thesis includes four different studies. In the first study 20 munic

Viral Loop Dynamics in Temperate and Polar Freshwaters

All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. Free virus-like particles in freshwaters are vulnerable and exposed and as p

Kostnadsredovisning som underlag för benchmarking och prissättning - studier av kommunal va-verksamhet

Popular Abstract in Swedish Den tekniska infrastrukturen i ett land rymmer en rad verksamheter vilka är att betrakta som naturliga monopol. För att hindra att monopolställningen missbrukas har verksamheterna ofta lagts under offentligt huvudmannaskap och regleringar har införts bland annat för att styra prissättningen. Priset regleras vanligtvis genom att avgiftsuttaget måste stå i någon form av rThis thesis, which consists of three studies illustrating different angles of approach, discusses problems pertaining to accounting and allocation costs in municipal water and sewage enterprises. Water and sewage enterprises are financed by charges to users, and are generally run under the auspices of a municipal administration or within the framework of a municipal company. User fees are regulat

Evaluating the performance of commonly used gas analysers for methane eddy covariance flux measurements: the InGOS inter-comparison field experiment

The performance of eight fast-response methane (CH4) gas analysers suitable for eddy covariance flux measurements were tested at a grassland site near the Cabauw tall tower (Netherlands) during June 2012. The instruments were positioned close to each other in order to minimise the effect of varying turbulent conditions. The moderate CH4 fluxes observed at the location, of the order of 25 nmol m(-2

Statistical analysis of coastal morphological data sets over seasonal to decadal time scales

Statistical analysis of long-term morphological data on coastal sedimentary features provides important information on the processes governing these features and their evolution in space and time. In this paper, seasonal, yearly and decadal (i.e. long-term) behavior of coastal morphological features is derived from field data by using both simple and advanced statistical techniques. The sedimentar

BMD, clinical risk factors and their combination for hip fracture prevention

This study examined the effects of the use of clinical risk factors (CRFs) alone, BMD alone or the combination using the FRAXA (R) tool for the detection of women at risk of hip fracture. BMD tests alone selected women at higher risk and a greater number of hip fracture cases were identified compared to the use of CRFs alone. The combined use of CRFs and BMD identified fewer women above a threshol

Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi

Popular Abstract in Swedish Nästan alla träd i våra skogar lever i samspel (symbios) med svampar. Många av dessa är ”vanliga” svampar, sådana som vi är vana vid att se och plocka i naturen, (exempelvis soppar, kremlor, riskor, flugsvampar och kantareller) men det finns också de som inte bildar fruktkroppar, eller har fruktkroppar som vi inte ser. Fruktkropparna, de som kan hamna i svampkorgen, är Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. Ectomycorrhizal fungi form mutualistic interactions with the roots of woody plants, including almost all boreal and temperate forests

Satellite remote sensing of primary production in semi-arid Africa

Popular Abstract in Swedish Ökningen av växthusgaser i atmosfären har orsakat en global temperaturhöjning. Afrika anses vara en av de kontinenter som kan komma att bli mest utsatta av effekterna kring ökande temperaturer med mer frekventa torkor som följd. Satellitdata ger oss möjligheten att uppskatta biomassa över stora områden vilket i sin tur kan leda till att öka vår förståelse kring hur utbyWith the challenges Africa faces with respect to the predicted warming due to climate change, the continents role in the global carbon cycle has been increasingly recognized. Earth observing satellites have played a significant role in the study of vegetation, particularly in Africa where climate stations are sparse. Satellite data can provide the means to map plant primary production for monitori

An Update on Research- & Bolar exemptions in the U.S. and Europe: Unsolved questions and new developments in an increasingly important area of law

In October 2017, the EU Commission announced a consultation on supplementary protection certificates (SPCs) and research exemptions, including Bolar-type provisions. The consultation will provide valuable input for the Commission when preparing an evaluation of the current EU legislation, and any future policy proposals on SPCs and patent exemptions, including the assessment of the impact of diffe

Evaluation of the contribution of germline variants in BRCA1 and BRCA2 to uveal and cutaneous melanoma

Germline mutations of BRCA1 and BRCA2 predispose individuals to a high risk of breast and ovarian cancer, and elevated risk of other cancers, including those of the pancreas and prostate. BRCA2 mutation carriers may have increased risk of uveal melanoma (UM) and cutaneous melanoma (CM), but associations with these cancers in BRCA1 mutation carriers have been mixed. Here, we further assessed whethe

Falls Predict Fractures Independently of FRAX Probability : A Meta-Analysis of the Osteoporotic Fractures in Men (MrOS) Study

Although prior falls are a well-established predictor of future fracture, there is currently limited evidence regarding the specific value of falls history in fracture risk assessment relative to that of other clinical risk factors and bone mineral density (BMD) measurement. We therefore investigated, across the three Osteoporotic Fractures in Men (MrOS) Study cohorts, whether past falls predicted

Association of Immune Marker Changes with Progression of Monoclonal Gammopathy of Undetermined Significance to Multiple Myeloma

Importance: Multiple myeloma is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS). Risk models that estimate the risk of progression from MGUS to multiple myeloma use data from a single time point, usually the initial workup. Objective: To longitudinally investigate the alterations of serum immune markers with stable vs progressive MGUS. Design, Setting, and Partic

Memory for Problem Solving: Comparative Studies in Attention, Working and Long-term Memory

Living in a complex and dynamically changing environment requires accurate and timely behavioural responses that allow for adapting to such changes. Well-developed perceptual systems provide a continuous flow of abundant and up-to-date information on the changes in the environment, and, thereby, allow for tailoring behavioural responses accordingly. However, issuing any behavioral response would n

Topographic controls of drought impact on Swedish primary forests

Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. However, topography is rarely included as a factor in research investigating vegetation dynamics

Evolutionary history of Zygaenidae: first comprehensive higher-level phylogeny and the estimated timing of lineage divergence

The 83 million year old family tree of burnet moths To classify the living world around them, early on humans started naming plants and animals in order to distinguish food from non-food, predator from prey, etc. In 1800s a practice of a more formal way of classifying the living world was started, in which using Latin names made the classification universal. The unique appearances were used to di

Effects on Gambling Activity From Coronavirus Disease 2019—An Analysis of Revenue-Based Taxation of Online- and Land-Based Gambling Operators During the Pandemic

Background: Concerns have been raised about increased gambling problems during the coronavirus disease (COVID-19) crisis, particularly in settings with high online gambling and risks of migration from land-based to riskier online-based gambling types. However, few non-self-reported data sources are hitherto available. The present study aimed to assess changes in the online- and land-based gambling

Nicotine, Alcohol Consumption, and Risk of Myasthenia Gravis : Results From the Swedish Nationwide GEMG Study

Background and ObjectivesMyasthenia gravis (MG), an autoimmune disease characterized by fluctuating muscle weakness, is believed to result from complex gene-environment interactions, yet few risk factors have been identified. The objective of this study was to determine the effect of nicotine and alcohol on MG disease risk.MethodsThe Genes and Environment in Myasthenia Gravis study is a Swedish, n

Recommended Medical Investigations in Pediatric Acute-Onset Neuropsychiatric Syndrome

Importance The clinical utility of the comprehensive laboratory and medical investigations currently recommended for children with pediatric acute-onset neuropsychiatric syndrome (PANS) remains unclear. Notably, comparisons with relevant psychiatric control patients without suspected immunologic pathogenesis are lacking. Objective To evaluate whether currently recommended laboratory investigations

The CD44(+)/CD24(-) phenotype is enriched in basal-like breast tumors

Introduction Human breast tumors are heterogeneous and consist of phenotypically diverse cells. Breast cancer cells with a CD44(+)/CD24(-) phenotype have been suggested to have tumor-initiating properties with stem cell-like and invasive features, although it is unclear whether their presence within a tumor has clinical implications. There is also a large heterogeneity between tumors, illustrated
