Jet and hydrocarbon fires are severe fires with the potential of creating large scale events which leads to serious accidents with both casualties and injuries. In this study, practical jet and hydrocarbon fire tests were carried out to assess standard ISO 834 based protection as well as improved passive fire protection. The tests showed that the ISO 834 protection is not sufficient. This standard
Ekonomistyrning i tjänsteföretag har under senaste åren varit ett väl debatterat ämne, uppmärksamheten har ökat alltmer med dess märkbara betydelse för ekonomin. Syftet med rapporten var att undersöka i vilket utsträckning ekonomistyrning tillämpas i små It-företag.
Syftet med uppsatsen är att undersöka hur finansiella instrument, med fokus på preferensaktier och obligationer, påverkar kapitalkostnaden i fastighetsbolag och hur dessa bolag motiverar sina finansiella strategier. Därtill undersöks den finansiella risken förknippad med kapitalstrukturen som beror på dessa instrument och hävstången i bolaget. Motiven till finansieringsstrategierna undersöks även The aim with this thesis is to evaluate how financial instruments, mainly preferred shares and bonds, affect the cost of capital in publicly traded real estate companies. We also want to investigate how the companies motivate their financial strategies of choice. With knowledge of the capital structures we make connections to the development of financial risk in the companies related to the financ
This thesis explored the path following applications of autonomous driving, where the purpose is to sense the environment and navigate to a goal without human intervention. Autonomous driving enables safer journeys by removing human error in driving, as well as reducing fuel consumption and driving time by optimizing the engine and brake actuation. In 2017 it is a well researched topic in the acad
Economic impacts of drought events can amass to billions of Euros within the EU. Ways to estimate the amount of water in the soil is thus very valuable to gather information which could be used for decision making. This thesis looks at different ways to estimate the amount of water in the soil, the so called soil moisture. The E-HYPE model from the Swedish Meteorological and Hydrological Institute
Untreated asthma limits the ability to live an active life, still many asthmatics does not have the level of control over their asthma as they could have. In addition, about 50% of the asthmatics use their inhaler incorrectly, which affects the result of the medicine negative. The asthma inhaler is central in an asthmatics living and has great potential for de- velopment towards a modern asthma mo
Throughout the developing world the informal (“black”) economy is a current issue. It constitutes a source of vulnerability to the people affiliated to it, and further hampers the nation´s economic performance. In addition it is at large unresponsive to policy change, and is further on difficult to monitor by government officials. The informal economy is a global problem. Previous studies on the i
The spread of pathogens between individuals has important effects on patterns of mortality, behaviour and the genetic structure of populations. One factor that is predicted to influence the transmission of pathogens is the genetic diversity of the host group. Groups of closely related individuals are susceptible to similar pathogens, and hence increase in genetic diversity of the group should decr
Människor spenderar mycket tid inomhus, närmre 90 % av sin livstid. För att erhålla ett bra inneklimat med god luftkvalité krävs att byggnader ventileras. Därför utrustas de ofta med mekaniska ventilationssystem. Trots detta är SBS (Sick Building Syndrome) ett allvarligt problem. Orsaken till att vissa byggnader blir ”sjuka” tros bero på bland annat dålig ventilation. För att avgöra om ett ventilaPeople spend a lot of time indoors, closer to 90% of their lifetime. To obtain a good indoor climate with good air quality buildings need to be ventilated. Therefore, they are often equipped with mechanical ventilation systems. Nevertheless, SBS (Sick Building Syndrome) is a serious problem. The reason that some buildings become "sick" is believed to be due to, among other things, poor v
I Sverige bedrivs en omfattande transport av farligt gods på vägnätet, vilket medför allvarliga risker för samhället (Stenberg, 2007). För att hantera riskerna från transporten föreslås riskreducerande åtgärder, vars effekter dock är osäkra (Sanglén, 2005). Mot bakgrund av det begränsade beslutsunderlaget vid fysisk planering av riskreducerande åtgärder för transport av farligt gods motiveras därf
The aim of this project was to investigate the effect of Lactobacillus plantarum 299v on the flocculating behaviour of beer starter culture yeast strains isolated from both top and bottom fermenting yeasts from a previous study (Li.Yu.,2014 unpublished). In the present study,microbial enumeration was done through basic culturing and plating techniques. Yeast strains and isolates of Lactobacillus p
Värdepapperiseringar och dess ekonomiska påverkan på den finansiella marknaden har sedan introduktionen av instrumentet på 60-talet varit ett utbrett verktyg framförallt för finansiella företag, men även för icke-finansiella företag. Men trots fenomenets praktiska utbredning på den värdepapperiserande marknaden, återfinns det desto mindre forskning och empiriska studier inom ämnet. Det har däremot
I februari 2016 lanserade Sveriges Radio nyhetsprogrammet Radio Sweden på lätt svenska, som riktar sig till andraspråksbrukare. Den här studien undersöker hur språket i nyheterna anpassas och hur väl andraspråksbrukare förstår dem i textform. Eftersom det finns relativt lite forskning om textanpassning för andraspråksbrukare syftar denna studie till att belysa konkreta språkliga aspekter som fören
Nanocellulose is being studied to a great extent around the world as it has great potential and many possible applications, for example, as an additive in greener polymers in a world where the need for replacements for fossil fuel based polymers increase. Different sources of cellulose are being considered for the production of nanocellulose as this can add value to what otherwise often is a by-pr
Bakgrund: Bipolär störning är en vanligt förekommande sjukdom som orsakar stort lidande hos de drabbade och deras närstående. Det är en vanlig diagnos som kräver livslång behandling. Förutom läkemedelsbehandling behövs även kunskap om copingstrategier. Syfte: Att beskriva hur personer med bipolär störning hanterar sin vardag. Metod: Litteraturstudie med med både kvalitativa och kvantitativa studie
Background. Lower tract respiratory infections are one of the most prevalent health problems worldwide. Influenza A is a main contributor to these infections, and infants are one of the risk groups for infection and developing serious lower respiratory tract complications. Better treatment for infants is needed, but little is known about the immune response that occurs in the lungs during infectio

Consumers’ knowledge that unsustainable consumption has a negative effect on the environment does not hinder their engagement in unsustainable consumption patterns. Applying system justification theory, it was of interest to investigate its impact on Swedish citizens’ attitudes and behaviours related to sustainable consumption. This study intended to discover why Swedish consumers do not always en
Tundra ecosystems are generally recognized as globally important carbon sinks, yet the knowledge on threats to such ecosystems is narrow. Climate change is predicted to reduce the number of muskox (Ovibos moschatus) in the arctic, it is therefore essential to understand the effect herbivores induce on the arctic ecosystem. The muskox is known as a keystone species in the arctic tundra. Such keysto
