The thesis is to develop a 3D printer that easily and conveniently can print with recycled plastic such as PET bottles, plastic packaging and much more. The printer will be designed according to the needs of a developing country. The idea is not to create an additive manufacturing factory but an effective manufacturing tool for the locals in the less developed parts of the country. The printer can

The master’s thesis was performed in collaboration with the department responsible for the driver vehicle interaction at Scania CV AB. The interaction between the driver and the vehicle contributes to the usability and overall experience of the product as well as to safety. In order to create a good interaction it is important to evaluate it. The purpose of the thesis work was therefore to develop

This thesis examines EU’s adoption of a human security approach and the extent to which it has been part of crisis management discourse as well as practice in the Sahel region of Africa. It tells the story of a maturing process for a core approach in EU security policy; that is, the story of human security and how the concept has evolved from a state of innocence to gradual experience and adolesc

The aim of this study is to examine how the need for belonging and search for an identity manifest themselves in the autobiographical works of two gay contemporary writers: Abdellah Taïa and Édouard Louis. Both authors have, during their childhood and adolescence, been confronted with a society that tried to exclude them for being ‘different’ and not fitting in the heterosexual norm. Suddenly, the

Under de senaste årtiondena har det i norra Europa och Nordamerika rapporterats om att sjöar och vattendrag blir allt brunare. Den bruna färgen kommer från naturligt organiskt material (NOM), vilket är material från döda djur och växtdelar, som transporterats med vattnet från intilliggande skog och mark. Denna ”brunifiering”, som den också kallas, tros bland annat kunna vara ett resultat av de pågDuring the last decades, increased concentrations of natural organic matter (NOM) and colour of surface waters have been reported from northern Europe and North America. Since surface waters are widely used for drinking water production this development has been problematic for drinking water producers. Even though NOM in itself is not harmful, it can cause production of undesirable disinfection b

This thesis describes an effort to enhance the control capabilities of an electric motor. It is in the interest of TetraPak that the research on this motor is performed so that it, in the future, can be a part of their production systems. The thesis has been separated into three main parts, where in the first part we are trying to find a model that describes the process. The second part describes

Offentlighetsprincipen är en grundläggande princip för Sveriges statsskick, som grundar sig på ett vertikalt förhållande mellan stat och individ. Principens syfte är att upprätthålla demokratin genom allmänhetens och mediernas möjlighet att få insyn i de offentliga organens verksamhet. Huvudförhandlingar, kallad rättegångar, vid domstolar, är som huvudregel offentliga. Likaså är offentlighet, i deThe principle of public access to information is a vertical fundamental relationship between the state and individual. The purpose of the principle is to maintain democracy. The public and the mass media have access to meetings of decision-making assemblies, and are entitled to attend trials the chamber of the swedish parliament, the municipal assembly, county council assembly and other such bodie

Under Covid-19 pandemin har distansarbete varit en central del i strategin för att minska smittspridningen av viruset. Före pandemin arbetade endast 5 % av arbetstagarna inom EU på distans regelbundet. När pandemin bröt ut ökade andelen distansarbetare inom EU till nästan 40 %. Den snabba omställningen till distansarbete har aktualiserat flera arbetsrättsliga frågor. Syftet med denna uppsats är atDuring the Covid-19 pandemic, telework has been a central part of the strategy to reduce the spread of the virus. Before the pandemic, only 5% of EU workers worked remotely on a regular basis. When the pandemic broke out, the proportion of employees working remotely in the EU increased to almost 40%. The rapid transition to telework has raised several issues of labor law. The purpose of this thesi

Uppsatsens syfte var att undersöka huruvida EU:s nya anfallsvinkel till migration, nämligen externaliseringav gränskontroller in i tredje länder, passar in i den Europeiska Unionens asylramverk. Vad som har analyserats ytterligare varom den här processen av att externalisera gränser har ändrat möjligheterna för migranter att få tillgång till asylprocessen. Forskningsfrågan som användes var: Hur paThe objective of the thesis was to examine howtheEU’snew approach to migration, namely externalizing border controlsinto third countries, fit into the European Union’sasylum framework. Furthermore, what has been analysed is how this process of externalizing borders has changed the opportunities for migrantsto access the asylum procedure. The research question was: How does externalizing the outer

This thesis investigates the legal professionals in Spain during the transitional period from the ancien régime to the liberal state, a period marked by institutional rupture, ideological conflict, and social reconfiguration. The study has the primary aim to understand how the legal professionals contributed, perceived, and resisted the extensive legal changes that took place approximately two cen

We report on the dynamics of in situ etching of nanowires using an etching agent which allows for parameter optimization for nanowire synthesis without concerns of tapering issues. Upon etching of InP nanowires using HCl it is found that HCl mainly reacts with the precursor TMI, its decomposition species, and physisorbed In. The reaction with solid InP is less rapid and diffusion limited. We find

It is a hallmark of natural language use that the way we talk about something reflects how it is represented in the mind of our conversation partner. This thesis studies the use and cognitive processing of referring expressions like one in comparison with other expression types in spoken Danish. The cognitive status of referents in other people’s minds can be understood in terms or referential g

Formaldehyde in aqueous solution is hydrolysed and forms methanediol. Using X-ray absorption spectroscopy we show that the hydrolysation product can be identified by a distinct electronic signature in the spectra. This is manifested by the disappearance of the oxygen 1s -> pi* absorption line. The X-ray absorption spectrum of aqueous formaldehyde is compared with those of the structurally similar

Modern power plants are all strongly dependent on reliable and accurate sensor readings for monitoring and control, thus making sensors an important part of any plant. Failing sensors can force a plant or component into non-optimal operation, cause complete shut-down of operation or in the worst case result in damage to components. Given their importance, sensors need regular calibration and maint

We used dynamic sorption balance measurements to evaluate the diffusivity for cement pastes with three different binders (OPC, OPC + 70% slag, OPC + 10% silica fume). The diffusion of water vapor in cement based materials is normally assumed to follow Fick's law of diffusion, but our results clearly show that Ficles law cannot completely describe the sorption process in our materials. In this pape
