Examensarbetet jämför tre olika metoder för dimensionering av en spont. Syftet med arbetet är att utreda hur de valda beräkningsmetoderna inverkar på dimensionerande snittmoment och dimensionerande förankringskrafter samt att undersöka hur resultaten från de olika beräkningsmetoderna varierar vid ändring av ingående parametrar. De tre beräkningsmetoder som jämförs är den analytiska metoden från SThis master thesis compares three different methods for dimensioning a sheet pile wall. The purpose is to investigate how the chosen calculation methods affect dimensioning moments and anchoring forces in a sheet pile wall and to investigate how the results from the different calculation methods vary when changing the input parameters. The three calculation methods that are compared are the analy

Three-dimensional food printing is an emerging application within the realm of 3D printing with the potential of transforming the foods we consume. The technique harbors incredible potential for improving the eating experience of people suffering from dysphagia, an ailment which causes discomfort at the time of swallowing. Patients suffering from this condition have special diets consisting of tex

At present, in potato starch industries, not only starch is extracted from the process but even proteins and fibers are recovered as they are economically valuable. Unfortunately, the process used for protein recovery can only partially recover protein from the potato fruit juice (PJ), while the reaming PJ is concentrated using an evaporator and is later on used as fertilizers. Potato starch indus

Aims. Until recently, most high-resolution spectroscopic studies of the Galactic thin and thick discs were mostly confined to objects in the solar vicinity. Here we aim at enlarging the volume in which individual chemical abundances are used to characterise the thin and thick discs, using the first internal data release of the Gaia-ESO survey (GES iDR1). Methods. We used the spectra of around 2000

Background: The production of bioethanol from lignocellulose hydrolysates requires a robust, D-xylose-fermenting and inhibitor-tolerant microorganism as catalyst. The purpose of the present work was to develop such a strain from a prime industrial yeast strain, Ethanol Red, used for bioethanol production. Results: An expression cassette containing 13 genes including Clostridium phytofermentans Xyl

This thesis adds to the knowledge base of how the Individual Placement and Support (IPS) can be optimized to secure a more sustainable working career for people with severe mental illness (SMI). The thesis has given the IPS-participants an active voice about what it is like to start to work in a Swedish context, visualised the psychiatric disability in relation to work, discerned the support and p

Popular Abstract in Swedish Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is

This thesis consists of three essays on VIX futures and options, and deals with issues highly relevant to all financial markets, such as understanding the operation of markets and developing flexible and tractable pricing models for contracts traded in them. It consists of four chapters. Chapter 1 provides a short introduction to the VIX and a brief explanation of how the old and new VIX are cons

The rationale for thrombolysis, the most promising pharmacological approach in acute ischaemic stroke, is centred on the principal cause of most ischaemic strokes: the thrombus that occludes the cerebral artery, and renders part of the brain ischaemic. The occluding thrombus is bound together within fibrin. Fibrinolysis acts by activation of plasminogen to plasmin; plasmin splits fibrinogen and fi

Popular Abstract in Swedish I december 1990 antog riksdagen i Sverige ett miljötillägg i skollagens s k portalparagraf: "Var och en som verkar inom skolan skall främja? respekt för vår gemensamma miljö." Alltså: Alla som verkar i skolan ska nu ta sig an den nya miljötematiken i samhället. Strax därefter tillsatte regeringen en ny läroplanskommitté med ett tydligt miljöuppdrag. I juni 1992, vid FNThis thesis explores the various influence processes that take place in connection with the dawn of a new theme - the environment - in today's society. Society has declared that schools, a place designed for the intentional influence of children and youths, shall utilise the new environmental theme in its practice. It focuses on the initiation process of the environmental theme in schools from the

Popular Abstract in Swedish Organiskt avfall utgör ett problem men är samtidigt en resurs med dess innehåll av näringsämnen och energi. Ett sätt att ta om hand organiskt avfall är att bryta ned det anaerobt genom s.k. rötning. Det organiska materialet reduceras då samtidigt som biogas produceras. Biogas består till största delen av metan som är energirikt och kan ersätta fossila bränslen vid prodAnaerobic digestion of organic matter results in the production of biogas, which can be used to replace fossil fuels. There is potential for increased biogas production at wastewater treatment plants by digesting urban organic waste either separately or together with the sludge. Biogas production could also be increased by sludge pre-treatment. The objective of this work was to evaluate the poten

Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. In study I, we demonstrated that 20% of the patients in a population-based series of 818 STS developed second primary malignancies. An increased risk of

Background: Rat models of peritoneal dialysis (PD) are useful for studying the physiology of peritoneal transport and evaluating new osmotic agents. Intraperitoneal (IP) solute concentrations and their evolution over time are easy to measure, but IP volume (IPV) is not. Direct volumetric measurements are the "gold standard;' but they are expensive and do not allow for repetitive measurements in th

It is of great interest and importance how different amino acid residues contribute to and affect the properties of a protein surface, Partitioning in aqueous two-phase systems has the potential to be used as a rapid and simple method for studying the surface properties of proteins. The influence on partitioning of the surface exposed amino acid residues of eight structurally determined monomeric

I dagens samhälle står ungdomarna inför flera problem i deras liv. För att handskas med dessa väljer ungdomarna olika sätt. Vid vissa tillfällen kan detta leda till att ungdomarna begår oönskade handlingar ur samhällets synpunkt. Genom att söka sig till gäng och därigenom leta efter svar på de problem som de ställs inför leds många ungdomar in i ett asocialt leverne. För att förhindra våra ungdomaIn today's society young people are faced with several problems in their lives. Young people choose different ways to deal with these. At times this can lead to young people committing undesirable actions from the society's point of view. By seeking to gangs and thus looking for the answers to the problems they faced led many young people into an anti-social lifestyle. In order to prevent

I Sverige finns lagstiftning, genom nu gällande konkurslag, som reglerar vad som gäller vid en konkurs. Av gällande rätt framgår att en central utgångspunkt är att säkerställa att borgenärskollektivets rätt och bästa tillvaratas. Mot denna bakgrund är det av grundläggande betydelse att säkerställa konkursboets tillgångar. En av konkursboets viktigaste tillgångar är gäldenärens olika avtal. Trots a

Climate change is a reality, with no indication of slowing down or reversing. Climate change causes extreme weather to occur more intensely and frequently. This poses a significant threat to critical infrastructures, which must adapt to withstand the new conditions they are increasingly exposed to. Climate change adaptation are measures which have the purpose to lessen the negative effects of clim
