Water hardness is caused by magnesium and calcium ions (Mg2+ and Ca2+), and can result in formation of deposits, destruction of soap and increase of copper corrosion in old plumbing pipes. To soften the originally hard groundwater supplying 20% of Malmö’s drinking water, Bulltofta water treatment plant imports burned lime from Germany. Approximately 66 mg/L calcium is removed in the treatment plan

In this degree project it is discussed how to design an alpine navigation device for experienced to expert users to reduce cognitive load of orienting, locating, and navigating. You Are Here explores the state of navigating in alpine environments with digital and analog devices through user-centric research. Listening to professionals and journey mapping device interactions reveals the need for a

This thesis analyses the effect of the prevalence of family planning on the three dimensions of the Human Development Index (HDI) in low income countries. The sample consists of 75 countries with annual data from 1990-2018. Empirics indicate that falling fertility rates, due to increased availability and use of family planning, should increase GNI per capita, education and health. The outputs from

The aim of this thesis is to investigate and evaluate the use of escape filters during the construction phase of tunnels and mines. To achieve this aim three main research methods were used. Firstly, a literature review was produced to evaluate the current research about escape filters and fire safety during the construction phase of tunnels and mines. Secondly, interviews were conducted to find r

In recent years, the issue of the climate has aroused exponentially increasing interest and it is a common priority on the political agenda worldwide. The European Union Emissions Trading System (EU ETS) is the first and largest international system of trading with carbon emissions and it is sometimes described as the cornerstone in EU climate policy to combat climate change with its main objectiv

I denna uppsats behandlas begreppet ”väsentlig anknytning” i ljuset av anknytningsfaktorerna bostad, familj och ekonomiskt engagemang. Förhoppningen med uppsatsen har varit att klargöra när en person anses ha väsentlig anknytning till Sverige efter utflyttning och försöka klargöra hur praxis utvecklats. Sedan internationaliseringen slog igenom har det blivit vanligare och enklare att förflytta sigThe aim of this study was to investigate the meaning of “significant connection” in the light of the connecting factors housing, family and financial commitment. The hope with the thesis has been to clarify when a person is considered to have a significant connection to Sweden after moving out and try to clarify how the practice has developed. Since the breakthrough of internationalization, it has

Denna studie avsåg att undersöka förekomsten och fördelningen av psykologisk trygghet och affektivt engagemang hos kontorspersonal som arbetar i team. Vidare syftade denna studie till att undersöka till vilken grad variablerna samvarierar med varandra, samt gentemot olika demografiska faktorer. På grund av undersökningens tvärsnittsdesign kunde inga kausala samband fastställas. En digital enkät skThis study intended to examine the prevalence of psychological safety and affective commitment among white-collar workers who work in teams. Furthermore, the study intended to explore if the variables correlated with each other and in relation to demographic variables. Due to the cross-sectional design of the study, no causal relationships could be determined. A digital survey was sent out through

Världen och samhället på alla nivåer har i samband med Covid-19 ställts inför en kris. I organisationer bär ledarna i samband med en kris ansvaret för krishantering. Denna uppsats analyserar ledares upplevelse av att leda i kris inom organisationer samt ger förslag för hur krisledarskap kan förbättras. Uppsatsen har en kvalitativ ansats och den deskriptiva fenomenologiska metoden ligger till grun

The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions. This report also investigates if this risk can be

This paper examines the trade effects of increased trade policy uncertainty following the Brexit referendum by viewing the referendum’s influence on UK exports of goods to EU27 during the time period 2012-2019. This is done to give insight of how trade policy uncertainty can impact real economic behaviour, even when no classical trade barriers are changed. Methodologically, this is approached by e

To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (

The aim of this paper is to study what role sustainability commitments of the target company have on merger strategies by studying bid premiums determinants between the years 2000 and 2020. The paper uses multivariable regression models that include, among other variables, the degree the target company commits to sustainability and the difference in how much the target and the acquirer commit to s

There have been much effort during the last decade towards resilience of critical infrastructures, but the research differs and resilience within critical infrastructures is still seen as a relatively new and unexplored area. The purpose of this work is to provide an understanding of how critical infrastructures in Sweden work with resilience. The objective is to create a general framework that ca

Tucker Carlson Tonight och Hannity är två konservativa, republikanskt vinklade, nyhetsprogram på den amerikanska nyhetskanalen Fox News (Grynbaum, 2020). Under sommaren år 2020 hade de två programmen flest tittarsiffror av alla amerikanska program på kabelkanaler i USA. Detta, trots att de stödjer ett republikanskt parti som enligt V-deminstitutets demokratiindex under flera år brutit mot ett fler

Aim: The aim was to describe to what extent people with stress related illness engage in physical activity, which types of physical activity they perform and their perceived occupational value when performing physical activity. Met

Uppsatsen analyserar forskningslitteraturens orsaksförklaringar till den muslimska radikaliseringen i Tjetjenien från 1990 fram till och med 2000 talet. Frågeställningarna som besvarats berör faktorerna bakom radikaliseringen i Tjetjenien, vilken plats islam har i förklaringar till radikaliseringen samt vilka likheter och skillnader det finns i olika orsaksförklaringarna. Radikaliseringens orsaksf

I denna uppsats har jag analyserat hur karaktärerna i tv-serien I Mumindalen framställs ur ett genusperspektiv. Att valet föll på tv-serien hade främst att göra med att jag såg hur barn bearbetar det de ser genom den fria leken och önskade därför undersöka närmare vad som egentligen förmedlas via tv-program för barn. Tv-serien bygger på Tove Janssons böcker och mitt urval begränsades till de avsni
