Inom besöksnäringen är delningsekonomins utbredning särskilt tydlig och inom denna industri återfinns en rad företag såsom Airbnb, Vayable, Getmyboat, OffWeFly, EatWith, Uber, Fodora och Travelbuddy. Airbnb, som förmedlar uthyrning av privatpersoners bostäder som en sorts hotellrum, är kanske det mest välkända företaget. Typiskt för delningsekonomin i tjänstesektorn är digitala plattformar som sam
I omställningen till en mer hållbar bioekonomi har mycket fokus legat på utvecklingen av biobränslen. När det gäller innovation och utveckling av kemikalier och andra produkter släpar utvecklingen efter av flera orsaker, vilket visas i denna avhandling.Forskningen visar att det nuvarande systemet är inlåst i ett fossilberoende av flera olika orsaker, både tekniska, organisatoriska och materiella. The transition to a bioeconomy is dependent on transformative changes to technologies, organisations, and institutions, which jointly can be described as a socio-technical change. The thesis contributes to the understanding of how the transition is shaped by expectations on and collaborations for innovation forbiorefineries, which can produce chemicals, fuels, and materials needed in a bioeconomy.
Cementproduktion står idag för en ansenlig andel av världens koldioxidutsläpp, vilket driver utvecklingen av bindemedel med lägre koldioxidutsläpp. För utsläppen i ett längre perspektiv är dock de nya bindemedlens beständighet absolut avgörande. De flesta nedbrytningsmekanismer är direkt relaterade till både fukt- och jontransport. Dessa processer har undersökts i många studier, men huvudsakligen Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. Most degradation of concrete structures is closely related to both moisture transport and ion transport. Many studi

Abstract: Background: Matrix Gla protein (MGP) is an extrahepatic protein that is dependent on glutamate carboxylation, a vitamin K-dependent process. Its dysfunctional form, desphosphouncarboxylated- MGP, has been associated with increased arterial calcification and stiffness. The aim of this study was to measure the degree of postoperative carboxylation of MGP and two other Gla proteins in patieBACKGROUND: Matrix Gla protein (MGP) is an extrahepatic protein that is dependent on glutamate carboxylation, a vitamin K-dependent process.

BACKGROUND: Dextran-70 is a more potent plasma volume expander than albumin but use has been hampered because of it's antithrombotic properties. However, also albumin has antithrombotic properties and little is known about relative effects of these two colloids on coagulation in-vivo when controlling for differences in efficacy as plasma volume expanders.AIM: Compare effects of dextran-70 and albu
Jordbruksmodernisering har dramatiskt ökat tillgången till mat på global nivå, men till ett högt pris för miljön. Idag efterlyser många ett ’paradigmskifte’ i jordbruket, även flera stora mainstream-institutioner. Med ett skifte till vad? Under senare år har det synts en ökande tilltro till agroekologi, ett alternativ som syftar till att förstå och bedriva jordbruk som komplexa agroekosystem. FrånAgricultural modernization has massively increased global food supply, but at a high environmental cost. Today many are calling for an agricultural ‘paradigm shift’, including several mainstream institutions. But to what? In recent years, agroecology has gained credence as an alternative approach that seeks to understand and manage farms as complex agroecosystems. From a development perspective, i
As urban areas expand rapidly worldwide, wildlife is exposed to a wide range of novel environmental stressors, such as increased air pollution and artificial light at night. Birds in highly polluted and/or urbanized habitats have been found to have increased antioxidant protection, which is likely important to avoid accumulation of oxidative damage, which can have negative fitness consequences.

Introduction: Ethiopia has one of the largest number of adolescents living with HIV (ALHIV). As these adolescents reach adulthood they need to transfer from pediatric to adult-oriented clinics. Clear implementation guidelines for transition are lacking and factors associated with successful transition are inadequately investigated. Our objective was to describe the rate and age of transition from
The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. In recent years, PET technology has been developed and improved in hardware and
The complement system is an essential effector of both innate and acquired immune responses. Due to its destructive potential, tight regulation is required. The contribution of complement has been associated with the pathogeneses in a wide range of diseases. In this thesis, aspects of complement activation were investigated in disorders characterized by thrombocytopenia.In papers I and II, clinicaThe complement system is an essential effector of both innate and acquired immune responses.

This report aims to investigate how Swedish municipalities work and could work to step up building developers responsibility to remediate polluted sites. This is done through the study of reports from environmental authorities, environmental legislation, legislation for society planning and interviews with officials at the municipalities Malmö, Lomma, Landskrona and Helsingborg. The study shows th
Elavbrott på ett oljeraffinaderi kan inte uteslutas, kan vi förutspå vilken inverkan det skulle få? Över livstiden av ett oljeraffinaderi är det till och med troligt at dess elektriskt drivna pumpar havererar minst en gång. Det orsakar en våg av varm olja som färdas genom fabrikens rör och enheter. Med hänsyn till att processen redan utförs vid flera hundra grader Celsius, vilken temperaturökningA dynamic simulation of the reactor loop of a standard hydrotreater was created in the software Dynsim by Invensys. Using simulations on the same plant from ProII, a steady-state process simulator, for adaption a good level of accuracy at steady state could be achieved and a heatwave simulation could be examined and investigated. The core to have a reliable outcome of the heatwave simulation in te
This report outlines a method to price and hedge a generalized swing option based on the European natural gas and electricity markets. The method is model free in that is does not assume a certain spot price dynamics. It only requires a forward curve and European call options prices that cover the delivery period of the swing option. The results is a lower bound derived from the price of forwards
I denna uppsats jämförs de svenska häktnings- och restriktionsreglerna med motsvarande norska och danska regler. Uppsatsens syfte är att, utifrån skillnader mellan regelverken, undersöka vilka rättspolitiska argument som kan göras gällande för att de svenska häktnings- och restriktionsreglerna borde ändras. I uppsatsen används två metoder, komparativ metod och rättsanalytisk metod. Den komparativaIn this paper, the Swedish law regarding pre-trial detention and restrictions against detained persons are compared with equivalent Norwegian and Danish laws. On the basis of differences between Swedish law compared with Danish and Norwegian law, the survey’s purpose is to study which justice political argument that can be made for a change of the Swedish law regarding detention and restrictions a
Uppsatsen handlar om vilka faktorer det är som gör att förvaltningsbeslut och förvaltningsmål karaktäriseras som tviste- eller brottmålsliknande. Denna karaktärisering leder i sin tur till att förvaltningsbeslutet eller förvaltningsdomen vinner negativ rättskraft så hinder föreligger för ny prövning av samma sak. Myndighetsbeslut och förvaltningsdomar vinner som huvudregel inte negativ rättskraftThis note analyzes the factors that determine whether administrative decisions and opinions are characterized as civil proceedings or criminal proceedings. This characterization, in turn, determines whether the prohibition on double jeopardy (so called “legal force”) applies, so that there is a barrier to a new trial of the same issue. In the paper, the rules on enforceability are the same in the
Sedan januari 2017 bedriver Riksbanken ett projekt vars syfte är att utreda huruvida digitala kontanter vore ett lämpligt komplement på den svenska betalningsmarknaden. Inom ramen för Riksbankens projekt kallas dessa digitala kontanter för e-kronor. Eftersom en övervägande andel av svenska betalningar redan idag görs elektroniskt kan det framstå som obegripligt varför Sverige alls skulle vara i bThe Swedish central bank started a project in January 2017 with the objective to explore whether digital cash would be relevant to the Swedish payment infrastructure. The central bank digital cash is referred to as ”e-kronor”. It may seem peculiar why Sweden would be in a need for digital cash since the current adoption of electronic payment is very high.
