Amorphous Silica (ASi) is present in considerable amounts in most soils and serves as a (micro-)nutrient for many plants. However, our understanding of the response of this important nutrient pool to human or natural disturbances is still very limited. One of the reasons for this is the long time scales involved. This explorative study focuses on the effect of a historical agricultural system, cal
Popular Abstract in Swedish Denna sammanläggningsavhandling i fysisk planering visar hur viktig rättens och juridikens roll är för planeringen och styrning av landskap och miljö, och de fall som studerats och analyserats är den svenska utbyggnaden av 3G-infrastruktur och vindkraften. Utifrån ett rättssociologiskt planeringsperspektiv visar Stefan Larsson (som också disputerat i rättssociologi tidiThis PhD thesis in Spatial Planning argues for the importance of understanding the approaches to knowledge and rationalities embedded in spatially relevant decision-making. It emphasises the significance of seeing law as an empirical object of study for planning and environmental management. The Swedish development of wind power and 3G mobile infrastructures are used as cases to study these issues
The urinary bladder is responsible for storage and expulsion of urine. Proper urination depends on an ability of the bladder to adjust to increasing volume and to contract during micturition. A disturbance of bladder contractility may affect continence. In the present thesis I have used genetic, biochemical and physiological approaches to examine the role of caveolae and mircoRNAs in bladder funct
To study the role of serum testosterone (T), estradiol (E(2)), and SHBG as regulators of peak bone mass and bone turnover rate in males, a cross-sectional study with data on lifestyle factors collected retrospectively was performed in 204 young Finnish men, 18.3-20.6 yr old. One hundred fifty-four men were recruits of the Finnish Army, and 50 were men of similar age who had postponed their militar
The F344 rat carries alleles contributing to bone fragility while the GK rat spontaneously develops type-2 diabetes. These characteristics make F344xGK crosses well suited for the identification of genes related to bone size and allow for future investigation on the association with type-2 diabetes. The aim of this study was to identify quantitative trait loci (QTLs) for bone size phenotypes measu
Climate warming is more pronounced in the Arctic than in other parts of the world. This warming affects the terrestrial cryosphere including permafrost with consequences ranging from societal impacts to changes in hydrology and feedbacks in the climate system such as those imposed by changing greenhouse gas exchanges. Permafrost dynamics in a marginal zone for its very existence is in this context
The plant plasma membrane H+-ATPase is a predominant membrane enzyme that provides the energy for secondary active transport across the plasma membrane. Consequently, the H+-ATPase is thought to play a major role in many cell processes, and it is implicated to be regulated by a number of factors, including hormones, blue light, and fungal toxins The plant plasma membrane H
Bakgrund: Den kurativa behandlingen för resektabla lokalt avancerade stadier av cancer i munhålan innefattar i regel en kombination av kirurgi och radioterapi (RT). Huruvida RT bör ges först och därefter följas av kirurgi, eller om tumören bör opereras bort först, följt av RT postoperativt, har dock inte studerats i någon större omfattning.Syfte: Denna avhandling undersöker olika aspekter av pre- Background: The curatively intended treatment for resectable locally advanced stages of oral cavity cancer (OCC) generally involves a combination of surgery and radiotherapy (RT). However, whether to apply RT first and then proceed with surgery, or to resect the cancer and subsequently administer RT, has not been extensively studied. Aims: This thesis examines various aspects of pre- versus postop
Fine-grained windblown deposits, known as loess, in which fossil soils (palaeosols) are preserved, serve as excellent records of past climate. However, paleoclimate reconstruction studies on loess-palaeosol sequences (LPS) in Southeastern Europe have primarily focused on climate changes during the last one or two glacial-interglacial cycles. Surprisingly, little attention has been given to the cli
In 1997 Tetra Brik Packaging Systems (TBPS) introduced the Prisma family into the portfolio. The family, which contains four volumes: X ml, 330 ml, 1000 ml and 2000 ml, is characterised by having eight panels at mid height. The new shape of the packages has forced TBPS to make modifications in the equipment and alterations in the distribution chain, from producers to consumers. This master's
Bankerna visar en hög tilltro och en positiv inställning till hur risk mäts i Basel II. Det är framför allt möjligheten att minska kapitaltäckningsgraden som ger upphov till den positiva attityden. Den finansiella turbulensen hade förväntats medföra ett större ifrågasättande av Basel II och dess riskbedömningar, men så är inte fallet. Det verkar dock finnas ett samband mellan bankernas tilltro til
Northern Europe was capped by ice during Weichsel (Wurm), the maximum of which occurred approximately 18,000 years before present. When in the latter part of the 19(th) century the view of an all-devastating land ice (the tabula rasa hypothesis) was generally adopted by natural scientists, plant biogeographers used a simple model predicting a post-glacial, northwards re-migration of species in con
Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. The surface associated M protein of Streptococcus pyogenes, a common human pathogen, exhibits antigenic variation due to an N-te
Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. Sandy coasts are dynamic systems. Thus, risk assessments and coastal manage
As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. The use of chemical energy carriers and fuel cells offers the possibility of a completely green solution for energy distributio
Popular Abstract in Swedish Sammanfattning Mänskliga aktiviteter och klimatförändringar påverkar vegetationen över hela jorden, idag och i framtiden. Denna påverkan kan studeras och kvantifieras med hjälp av observationer från satelliter vilka förmedlar information om vegetationsförändringar i tid och rum. I denna doktorsavhandling har metoder för analys av vegetationsförändringar utvecklats och Abstract This thesis aims to advance the analysis of nonlinear trends in time series of vegetation data from Earth observation satellite sensors. This is accomplished by developing fast, efficient methods suitable for large volumes of data. A set of methods, tools, and a framework are developed and verified using data from regions containing vegetation change hotspots. First, a polynomial-fittin
