From astrophysical and cosmological observations, it is known that most of the matter in the Universe is dark. This matter could be explainable by new particles, not included in the Standard Model of Particle Physics. This work assumes that there exists an interaction between dark matter and Standard Model particles, and investigates if the present relic density of dark matter in the Universe coul
Målet med arbetet har varit att ta fram en metodik för hur industriparker ska arbeta med tillskottsvatten och okända avloppsströmmar. Resultatet av arbetet har blivit ett förslag på en metodik för att identifiera okända strömmar av avloppsvatten och tillskottsvatten i ett avloppsledningssystem för spillvatten inom en industripark. Metoden är framtagen genom en litteraturstudie och från erfarenheteMany water managers manage to reduce the amount of Infiltration/Inflow (I/I) that is added to the sewer system. The reason for this is to reduce the number of basement flooding and overflows. This is not the case in Perstorp industrial park. The wastewater treatment plant in the industrial park has a permit on how much water the wastewater treatment plant is allowed to release into the recipient,
The purpose of this study is to explore the need for horizontal agricultural diversification in Guinea-Bissau (given the prominence of cashew crop monoculture in place in the country), how horizontal agricultural diversification is intended and planned by the current policies and what are the factors that hinder the implementation of such policies. A case study research strategy was selected to de
When the Lebanese civil war ended in 1990, the government estimated 17,415 persons missing or forcibly disappeared, of which most fates remain unknown. This thesis examines the truth-seeking process of the missing and forcibly disappeared people and its contribution to the reconciliation process in the context of Lebanon. The foundation of analysis is the truth-reconciliation theory, in combinatio
Marketization of the humanitarian system and the financial independence is thought to have an impact on humanitarian organisations’ behavior. With an increased insecurity for aid-workers and thus investment in aid-worker security management, research on this matter is pressing. This thesis seeks to examine the characteristics of the relationship between humanitarian organisations’ financial (in)de
Mängden koldioxid i atmosfären är ett av de största diskussionsämnena när det kommer till miljöförstöring i dagens samhälle. Koldioxid i sig är en gas som är svår att utföra kemiska reaktioner med eftersom den är mycket oreaktiv. Den består av ett kol och två syre som är hårt bundna till kolet med dubbelbindningar. För att kunna reagera måste någon av dessa bindningar brytas vilket kräver energi. The formation of [PCN-Ni-OAc] from reaction of [PCN-Ni-Me] with CO2 was followed by 1H NMR to determine the kinetics of the reaction. The second order rate constant was calculated, and the entropy and enthalpy of activation was obtained. The PCN-ligand were synthesised followed known synthetic routs. The crystal structure of the [PCN-Ni-I] complex was also obtained. A POCN- ligand was also synthe
Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases. In this thesis, an attempt has b
This thesis explores the communities surrounding true crime. This is explored in a qualitative manner, by studying four different communities surrounding criminal cases, as well as two interviews with people who consider themselves a part of the communities. The observations have been carried out on the forums: Reddit and Websleuths, as well as a chat-server on Discord. The aim of the thesis is to
The starting point for the modern pornography that exists today was after the first Playboy magazine was released. The rapid spread showed that there was a market for this. The purpose of this paper is to highlight the debate on pornography in Sweden. The survey is done through a content analysis that will analyze eighteen different articles. The theories that are used are Andrea Dworkins theory o
Feministisk utrikespolitik har sedan 2015, då utrikesminister Margot Wallström deklarerar denna inriktning, varit ett diskussionsämne inom den svenska utrikes-politiken. Uppsatsens analys genomförs med målet att åskådliggöra skillnader i hur regeringarna framställer kvinnor, hur de inkluderas och vilka rättigheter de har i de utrikespolitiska debatterna 2008 och 2015. Syftet med undersökningen är The Swedish feministic foreign politics has been a subject of political discussion since 2015 when the foreign minister, Margot Wallström, declared this new di-rection of the Swedish government. The thesis analysis is carried out with the aim of illustrating differences in how governments portray women, how they are included and what rights they have in the foreign policy debates in 2008 and 2015.
This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. The region between these two contacts is a junction, being Laser Activated Electronics Transistors are often considered the most revolutionary electrical devices of this century, attributed as the building block of all modern technology. It is these tiny devices that control the flow of electrons in all your electronics. In your computer alone, there are hundreds of millions of these transistors, all working together in a complex circuit. Previously, impr
For this 15 credits bachelor project in industrial design I focused on menstruation, a biological function that occurs to half of the population. I explored the disposable and reusable period care products on the mar- ket today and how many products an average menstruating person will consume and their environmental impact. This led me to the idea of de- signing an internal reusable period care pr
Bakgrund: Personer med allvarlig psykisk sjukdom riskerar minskat engagemang i dagliga aktiviteter, främst gällande förluster av mängden individuellt meningsfulla aktiviteter. Samtidigt har arbetsterapeutiska interventioner som möjliggör engagemang i meningsfulla aktiviteter visat sig vara stödjande för personernas personliga återhämtning. Det finns dock bristande kunskap gällande vilken betydelse
Problem definition Nowadays society is very concerned with sustainability. Companies try their best to meet sustainability customers’ expectations and regulations. The adoption of Lean and Six Sigma could bring sustainability improvements, but it is not clear how these three areas are combined and how they are currently addressed by companies. Purpose Explore the relationship between Lean, Six Sig
Uttrycket “övervakningssamhälle” är något som det talas om mer och mer. Vilket inte är så konstigt då många allmänna platser ofta är övervakade med antingen film eller ljudupptagning. Att kunna identifiera individer som på något sätt har brutit mot lagen eller förutse oönskade situationer är något som stärker vår säkerhet och ordningen i samhället. I många länder ses detta som helt nödvändigt och This report describes the product development process of a new product series of camera housings, adapted for modular applications. The purpose of the project was to develop a module containing a wiper, adapted for outdoor camera housings. The master thesis was performed at Axis Communications AB, a leading company in the surveillance camera industry. The camera housings of outdoor surveillance ca
När byggnader och broar ska dimensioneras är det viktigt att knutpunkterna för konstruktionen är noggrant beräknade. För att utföra beräkningar som tar hänsyn till knäckning och andra fenomen används ofta datorberäkningar i viss utsträckning. Det tar ofta oerhört lång tid, både för användaren att skapa en modell för konstruktionen i den grad av detalj som behövs, samt för datorprogrammet att beräkWhen designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. For most projects it is not reasonable to analyze a complete structure in exact detail and therefore simplified methods are used
Inventory control is a subject that impacts more or less every section of most businesses, hence companies today view it as a crucial problem of strategic importance (Axsäter, 2015). Managing inventory is a complex task which can be made even more complex by considering multiple items interacting with each other throughout the supply network. This master thesis attempts to show, through a case stu
In wireless communication, resources like bandwidth and energy are scarce and extremely valuable, any system should serve as many users as possible while preserving high Quality of Service (QoS) for the best user experience. Accordingly, the Base Station (BS) has the responsibility to optimally schedule its resources to the users based on the available information. Consequently, the whole process
This project investigates what human interaction is and how we collaborate within the confines of finite resources. The project ex- amines what could be done to minimise the need of ownership and instead reconnect the human to the collective by encourag- ing sharing. The method used to achieve this will be an in-depth design process. The investigation is conducted from the stand point of a Swe
