The blood-brain barrier (BBB) is a highly selective barrier separating the brain from the circulatory system. The physical barrier is built up by a monolayer of endothelial cells, which is the main component used for in vitro modeling. To create more physiologically relevant in vitro models, the field of organs-on-chips has recently been introduced, combining microfluidics and microengineering to

Den här studiens primära syfte är att jämföra och utvärdera två medborgardialogs metoder. De två metoderna är samrådsmöten och Public participatiory GIS (PPGIS). Samrådsmöten är en etablerad metod inom medborgardialog för samhällsplanering i Sverige. Uppsatser syftar till att pröva hypotesen om PPGIS är en effektivare metods för medborgardialog. Uppsatsen utvärderade först de två metoderna med hThe primary purpose of this study is to compare and evaluate two public participation methods. The two methods are public meetings and Public participatory GIS (PPGIS). Public meetings are an established public participation method for urban planning in Sweden. The thesis aims to test the hypothesis if PPGIS is more effective as a public participation method. The thesis first evaluated the two me

Beer is one of the most favorable alcoholic beverages and has a large consumption in the world. However, there are fewer beer consumers who perceive the lacing character after drinking. Four different concentrations (25 mg/L, 50 mg/L, 75 mg/L and 100 mg/L) of iso-α-acid and two levels (0.3% and 0.15%, w/w) of protein content were investigated towards lacing property on modified hydrophilic and hyd

The company has specialized at making check valves and flow regulators and wanted to develop their products further by implementing technology and creating a system where their customers can monitor the water flow in real time. My task was to look at the different opportunities of what and how this could be done and from that make a concept fully adapted for their needs. From interviews and resea

English as a second language (ESL) classrooms in Sweden constitute multicultural and social platforms where different language backgrounds and attitudes meet and where norms intersect, are contested and negotiated, creating possibilities for some, but limitations for others. The Swedish National Agency for Education promotes norm critical pedagogy (NCP) as a means to tackle degrading treatment and

Purpose The purpose of this study is to examine influencer marketing’s effect on customer-based brand equity and customers’ willingness to post brand-promoting user-generated content. Methodology An integrative mixed method approach, with qualitative pre-study for scale development and a quantitative (n=222) main study, has been applied for testing the communication forms effect on the concepts.

Police states are among the most invasive tools at the disposal of an autocratic regime- and the Chekist police state of the USSR is no exception. By arresting, imprisoning, or outright killing any person found to be undesirable or lacking adequate ideological fervor, Stalin’s police force left an indelible mark on the 1930s. They can be viewed as a form of political institution, and as such have

Någon gång i våra liv har vi tittat upp på natthimlen och skådat vår allt lojala kompanjon. Månen har genom mycket av människans historia setts som ett oupn åligt objekt, men år 1969 så gick människan bortom sina gamla bergränsningar och tog sina första kliv på Månen. Från månstenar som samlats in genom detta uppdrag så upptäckte vi att Månen en gång i tiden måste ha haft ett magma hav. Men det unIn this thesis we add a temperature dependence to the newly developed variable polytrope equation of state (Varpoly EOS) from Weppner et al. (2015), making it more universal and more applicable for planetary simulations. In this process we develop a new model for the Gruneisen parameter, which is a parameter that describes how pressure changes with the internal energy. This new model conforms to t

Second-hand retailing has seen a considerable upswing in recent years. Customers rethink their attitude towards a more mindful way of consuming which makes second-hand shopping increasingly popular. This research study took the Stimulus-Organism-Response framework as a foundation leading to its first-time application in second-hand retailing. The aim of this study was to investigate the relationsh

This is done by measuring the production rate of the strange φ meson in high multiplicity p-p collisions at √sNN = 13 TeV. The high multiplicity p-p events are then divided into different transver

Estimating area of polygons on the Earth’s surface is required in many fields in earth science. In the field of carbon modelling, one application of estimating polygons’ area is to estimate carbon flows for regions. This thesis aims to develop a methodology to estimate area of a polygon on a spherical/ellipsoidal surface applied to the problem to estimate carbon flows in regions. It is common th

Den här studien undersöker utvecklingsstadier i andraspråksinlärares förståelse, perception, av grammatiska strukturer i skrift i svenskan. Perceptionen mäts genom ett grammatikalitetstest, där informanterna antingen godkänner eller underkänner samt korrigerar meningar. Det förra betraktas här som passiv perception och det senare som aktiv perception. Studien utgår från Pienemanns processbarhetshi

This bachelor thesis studies the syntactic structures in four textbooks in German as a foreign language used in the Swedish upper secondary school (the gymnasium). The aim of the study is to test whether the German syntax is presented in such a way that it becomes optimally processable for learners. Research on grammatical developmental stages has shown that learners of a language acquire grammati

Bakgrund: Föräldrar till prematura barn påbörjar sitt föräldraskap tidigare än vad föräldrar som haft en fullgången graviditet gör. Detta innebär att föräldrarnas förhoppningar och tankar om barnet förändras och istället läggs fokuset på barnets överlevnad. Tiden är svår för föräldrarna och de utvecklar ofta känslor av stress, ängslan och oro samt hjälplöshet. Syfte: Att beskriva föräldrars upplev

Hjärttransplantationer syftar till att rädda liv men kan även vara riskabla ingrepp. Det är mycket som kan gå fel. Det transplanterade hjärtat lider stor risk att avstötas i mottagarens kropp, och en mer detaljerad kunskap om faktorerna som påverkar avstötning har således möjligheten att rädda liv. Avstötning orsakas av att mottagarens immunförsvar känner av HLA-molekylerna, där HLA står för HumThe beneficial effects of HLA matching at the HLA-A, -B and -DR loci on recipient short- and long-term survival in heart transplants have been established in a number of studies. The objective of the present study was to evaluate the importance of individual HLA alleles at the HLA-A, -B and -DR loci as risk factors for recipient death within one year after transplant by using artificial neural net

Since the outbreak of the Syrian crisis in 2011,the number of Syrian refugees reached approximately 3 million; nearly half of them are children. Although primary education has always been available, education services for Syrian refugees were subject to frequent changes particularly between 2011-2014. The biggest and most significant step was taken in the 2016/2017 school year as a result of long-

In this study, electrical resistivity tomography (ERT), induced polarization (IP) and transient electromagnetic (TEM) measurements were carried out to investigate two possible bedrock depressions as well as possible thermal water intrusion in the Challapampa aquifer, located on the Bolivian Altiplano north of the city of Oruro. Oruro presently cannot satisfy the demand for water and Challapampa aq

Runt om i världen pågår en omställning av energisystem på internationell, nationell och regional nivå av en omfattning som inte noterats på många årtionden. Omställningen innebär i första hand en övergång från fossila, icke förnybara energikällor till fossilfria, förnybara sådana med huvudsakligt syfte att begränsa de antropologiska klimatförändringarna och andra negativa effekter på miljön. Den fAll around the world, energy systems are transforming at the international, national and regional level and at a rate not seen for many decades. This transformation primarily involves a transition away from fossil, non-renewable energy sources and to fossil-free, renewable ones with the primary purpose of halting the process of anthropological climate change and limiting other adverse effects on t
