This thesis opens up the “black box” of business incubation and analyses how this process works in an incubator for cultural and creative ventures in Northern Sweden. The theoretical framework of the rites of passage by Arnold van Gennep and Victor Turner was adopted to guide the analysis. This theory indicates that one can move from one status to the next in a society through the means of differe

The aim of this MSc-project was to investigate whether it is possible to incorporate native cell membrane components from Jurkat T cells into supported lipid bilayers, SLBs, to produce a model membrane system better resembling the native cell membranes in T cells. The procedure of forming native-like SLBs (nSLB) was adapted from an existing protocol and is done through the deposition of hybrid ves

Sedan 2017 har elsparkcyklar fått ett stort genombrott i Sverige och har blivit ett allt vanligare transportmedel för att åka korta sträckor. Elsparkcyklar framförs i allt större utsträckning i urbana trafikmiljöer och detta kan innebära en större osäkerhet och otrygghet av elsparkcyklar i städerna och trafiksäkerheten kan påverkas negativt för oskyddade trafikanter. Detta examensarbete har som måSince 2017, electric scooters have become an increasingly common means of transportation in urbanized cities across Sweden for cover short mileage. Electric scooters are seen more often in urbanized cities and this can imply a greater sense of danger when the vehicles are driven more frequently in urban traffic environments, thus causing a greater impact on road safety for vulnerable road users. T

Trötta ögon, huvudvärk, för kallt eller för varmt och allmänt lägre prestationsförmåga. Så kan det se ut på ett kontor med dålig ventilation och detta minskar förtjänsten för företaget samtidigt som det för de anställda upplevs påfrestande. Med ett väl dimensionerat, och rätt valt tilluftssystem blir inomhusklimatet avsevärt bättre och de anställda har de bästa förutsättningarna att med glädje pre

Microbial water quality is often assessed with heterotrophic plate counts (HPC) which are not trustworthy and time consuming, and flow cytometry (FCM) with DNA staining by SYBR® Green I (SG) has been suggested as a suitable tool for analyzing the bacterial community in drinking water. This study investigated the existing staining protocol and then applied this protocol to monitoring of slow sand f

Bus lanes are being built as a measure to increase the share of public transport, thereby reducing congestion and environmental impacts. Evaluations are rarely made and the effects of the measures are therefore, in many cases unknown. It is currently unclear whether there are some general correlations between the Swedish cities where bus lanes have been built. This report examines the general tren

Antivirals for HPV infection Human papillomaviruses (HPV) are present in more than 99% of all cervical cancers and HPV-16 is one of the predominant types of HPV infections and account almost for 50% of cervical cancer cases. Although two vaccines are available on the market and showed notable promising in HPV prevention, there are still no available antiviral drugs for HPV infections. In this stu

Fotosyntetiserande växter, alger och bakterier fångar in och omvandlar solenergi till kemisk energi. Själva ljusinfångningen involverar olika pigment, varav de mest kända är de gröna klorofyllmolekylerna som förekommer i olika varianter (varav två varianter kallade klorofyll A respektive B förekommer hos högre växter). De ljusinfångande pigmenten inkluderar även de mer mångtaliga karotenoiderna, ePhotosynthetic organisms harvest and convert light energy into chemical energy and utilize it in their metabolism. The light is captured through pigments called chlorophylls and carotenoids, present in the thylakoid membranes inside the chloroplast. In addition to acting as auxiliary light harvesters, the carotenoids also act as antioxidants by 1) preventing the formation of reactive oxygen specie

När avfall kommer på tal, inte bara inom avfallsbranschen, finns idag ett stort fokus på att minska de totala avfallsmängderna och att öka utsorteringen av återvinningsbart material. Trots det ökar de nationella avfallsmängderna. För att göra arbetet med både avfallsminimering och en ökad utsorteringsgrad så verkningsfullt som möjligt, är det viktigt att veta vad som påverkar avfallsmängderna. SyfWhen waste is on the agenda, not only in the waste industry but in general, there is a high focus on reducing the amount of waste and to increase the amount of sorted recyclable material. Despite this, the total waste amount in Sweden is increasing. To be able to minimize the amount of waste and maximize the waste sorting degree it is important to know the factors that affect the waste stream. The

Den 1 januari 2019 infördes omfattande ändringar i det svenska företagsbeskattningssystemet. Från att tidigare endast begränsat avdrag för ränteutgifter hänförliga till interna lån innebär bolagsreformen att alla ränteutgifter begränsas och principiellt omfattas alla svenska aktiebolag av regelverket. Neutralitetsprincipen uttrycken en målsättning om att den skattskyldiges val mellan olika handlin

The purpose of the thesis is to explore and understand the meaning, sources, and role of brands’ perceived innovativeness to talents due to the proposed importance of the attribute within the so-called war for talents as well as contemporary theoretical and practical discourse. In accordance with the relativistic and interpretivist stance taken, a qualitative methodology is adapted through the uti

Climate change and the sustainability challenges of the 21st century require the reduction of greenhouse gas emissions in all sectors. Accordingly, political objectives urge for a shift from road to rail in logistics. This drives innovation, increased efficiency, and customer friendliness in the rail industry. These advancements are strongly needed as investments have been neglected in the past an

Genetic engineering of molds to produce new pharmaceutical compounds In this master’s thesis project, I investigated natural chemicals produced by fungi which are interesting for the pharmaceutical industry. Fungi are a very large family of organisms that we are still working to understand, and we continue to discover many new species every year. Living by growing on food sources and secreting en

I ett hållbart samhälle är tillgänglighet en viktig förutsättning för alla, oavsett deras bakgrund. Det finns olika komponenter som ingår inom begreppet tillgänglighet. En av dessa komponenter handlar om transportmöjligheten, att man ska ha möjlighet att transportera sig till olika punkter med minsta möjliga reseuppoffring. Detta kan uppnås med hjälp av kollektivtrafiken, eftersom kollektivtrafik In a sustainable society accessibility is vital and should be provided for everyone, regardless of their background. There are different components within accessibility as a concept. One of these components is transport, which has to do with the ability to transport to different destinations with minimum sacrifice. This can be achieved with public transport, because it’s available for everyone and

Det Palestinska Territoriet har sedan 1967 varit ockuperat av Israel. Som följd av ett stort antal oroligheter och protester mot ockupationen har Israel infört restriktioner för rörlighet inom Västbanken och Gaza. Rörligheten är styrd med hjälp av exempelvis vägspärrar och blockerade vägar. År 2002 började Israel bygga en betongmur runt om och inuti Västbanken, trots att det motsätter sig internatThe Palestinian Territory has since 1967 been occupied by Israel. Following a large number of disturbances as protests to the occupation, Israel has imposed mobility restrictions for Palestinians in the West Bank and Gaza. The mobility is regulated by for example checkpoints, roadblocks and earth mounds. In 2002, Israel started to build a concrete wall around and inside the Palestinian Territory o

Sammanfattning Under 1960-talet kunde vetenskapsmän konstatera att en generell uppvärmning av atmosfären resulterade i klimatförändringar. En av källorna till den globala uppvärmningen var och är fortfarande den höga koncentrationen av växthusgaser i atmosfären som uppstår genom mänsklig aktivitet vid förbränning av fossila bränslen. Trots den vetskapen dröjde det en bit in på 2000-talet innan kliSummary In the 1960’s scientists discovered that general heating of the atmosphere or global warming results in climate change. One of the reasons behind global warming is the high concentration of green house gases in the atmosphere, which is a bi-product of fossil fuel combustion caused by human activity. Climate change did not become a European Union priority before the 21st century when the c

Background: Previous research has focused exclusively on weight loss or weight maintenance following weight loss, i.e. secondary weight maintenance (SWM). The long-term results of SWM have been modest, suggesting that preventing initial weight gain among normal weight or overweight individuals, i.e. primary weight maintenance (PWM), may be more successful. The aim of this study was to compare the

Background: A number of single nucleotide polymorphisms (SNPs) have been associated with broadband ultrasound attenuation (BUA) and speed of sound (SOS) as measured by quantitative ultrasound (QUS) at the calcaneus in the Framingham 100K genome-wide association study (GWAS) but have not been validated in independent studies. The aim of this analysis was to determine if these SNPs are associated wi

Popular Abstract in Swedish Diabetes, i alla dess olika former, är en allvarlig sjukdom. Typ 1 diabetes är av autoimmun härkomst, då kroppen eget immunförsvaret attackerar och förstör β-cellerna i bukspottkörteln. Dessa celler producerar insulin som hjälper kolhydraterna i maten vi äter att komma kroppens celler till godo. Sverige har världens näst högsta antal nya insjuknanden, bara Finland har fThe role of miRNAs in pancreatic islets and β-cell function and in the development of diabetes in human and rodents have been investigated in this thesis. Dicer1 was specifically deleted in vivo in pancreatic β-cells under the RIP-promoter in mice. The results show that disruption of miRNAprocessing in mouse pancreatic β-cells, while compatible with β-cell development, leads to defective insulin-s

Bio-energy production from lignocelluloses biomass has gained a lot of interest in recent years. Miscanthus sp. are high lignocelluloses biomass yielding with relatively high carbohydrate content cultivable on different soils and under climatic conditions. However, the lignocellulosic nature means that cellulose and hemicellulose are cover by lignin network that might limit hydrolysis. In this stu
