Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). Tungmetallerna återvinns genom selektiv utfällning med hjälpThis thesis treats the development of an industrial scale models of a wastewater treatment process aiming at reducing the sulfate and heavy metal concentration in the effluent water from mining processes. The sulfate present in the process water is reduced using sulfate reducing bacteria (SRB) while the heavy metals are recovered through selective precipitation using the hydrogen sulfide produced

I denna avhandling har jag kritiserat EPI (Environmental Performance Index) och det sätt ett lands hållbarhetspolicy tenderar att mätas. Jag har granskat tidigare bortsedda aspekter av nationernas miljöpolicy och försökt föra dem fram i hopp om att dessa kommer att användas för framtida miljömätningar. Jag har också tittat på sambandet mellan jämställdhet och statlig miljö och försökt hitta empiri

Far-field three dimensional x-ray diffraction (3DXRD) data acquired by repetitive acquisitions with a beam much smaller than the sample width is sometimes referred to as scanning-3DXRD. We here analyse the scanning 3DXRD approach and present a novel reconstruction technique capable of reconstructing intra-crystal variations in crystal structure from a set of recorded 2D diffraction patterns. The m

Det finns idag robotar som är särskilt anpassade för att användas av räddningsteam i följderna av katastrofer som hjälpmedel i deras arbete att lokalisera och rädda människor instängda i trånga utrymmen. De är dock mycket dyra vilket begränsar deras användande och gör att användarna tvekar innan de skickar in en robot med risken att skada eller förlora den. Detta projekt dokumenterar det första stRobots currently exist that are specifically designed for use in the wake of disasters to help rescue teams in their work of locating and rescuing individuals trapped in confined spaces. However, they are prohibitively expensive which limits their adoption and causes the operators to think twice before they're deploying a robot with the risk of losing or damaging it. This project details the f

It is of importance for manufacturing companies to get an overview of costs associated with production. This thesis handles this subject with an emphasis on chosen cutting data as well as chosen tools since this has a large impact of the tooling cost. By modelling on cutting data available from tool manufacturers, cutting data can be implemented to test different cases in the production. This also

In recent years, the notion that Corporate Social Responsibility (CSR) schemes enable corporations to assume a role of a development agent has been heavily contested in academia. Among CSR schemes are the International Finance Corporation’s (IFC) Performance Standards, which, regardless of their foundational role in shaping the paradigm of responsible business, are yet to be exposed to thorough ac

The climate change is affecting small island developing states to the amount that the surface of Tuvalu might disappear and the country therefore risk to lose its sovereignty (Pacific Small Island Developing State 2009, p. 10-12). By investigating environmental security through climate displacement this thesis will conduct a case study of Tuvalu. The theory of ecofeminism and intersectionality wil

Density is often used as a strategy to achieve a sustainable development in contemporary urban planning. A higher concentration in the urban environment of functions and people are argued to be essential to handle the climate change as well as achieving social equity. While a desire for higher density is often formulated in urban development plans by regions or municipalities, there lies a confusi

Every year, a big number of Swedish municipalities market themselves through an Emigration fair in Holland, with the aim to attract Dutch workforce, or more generally, bring new inhabitants to their respective region. In the marketing campaigns, specific stereotypic images of Sweden emerge, that are said to be specifically attractive to the putative Dutch migrants. The municipal representation in

This thesis explores the European Commission’s proposal on General Reverse Charge Mechanism. VAT is a final tax on consumption. It is imposed on every transaction in the supply chain with the general aim of being deductible and thus being neutral for businesses with the right to deduct. The initial aim of the VAT system was to operate as if all the transactions occurred in one single country; howe

The purpose of this study is to explore the opportunities and challenges for self-employed artists who use social media for their business. The research is focused on painters and illustrators who have digitalised and commercialised their own artwork. The method follows a qualitative research framework with a comparative design of multiple cases on the level of individual artists. Seven artists fr

A study is carried out on the ventilation strategies for road tunnels in different countries and consequences using fixed fire fighting systems (FFFS). The type of ventilation strategy for road tunnels can ensure the safety of people during the evacuation stages and protection of the rescue services during their intervention of the fire. Ventilation strategies vary from country to country and ther

Purpose: The purpose of this study was two-fold. First, we aimed to develop a framework concerning how to directly and indirectly control discrimination in the workplace using Man- agement Control Systems (MCS). Second, we wanted to examine whether this framework is practically applicable in multinational enterprises (MNE). Methodology: The first part of the purpose was achieved through conduc

Transitioning to a circular economy requires designing products that are meant to remain within and cycle through economic systems. While circular product design principles have been applied across industries, the medical industry presents unique challenges with its complex regulatory requirements and the high-risk nature of innovating with medical products. This thesis aims to contribute to the i

Research purpose: This study aims at finding out (1) how retailers' sales can be influenced if customers are offered to use SSTs (self-service technologies) for navigating themselves directly to the items they want to buy. (2) how the shopping experience can be influenced if customers are offered to use SSTs for navigating themselves directly to the items they want to buy. Methodology: Based o

The aim of this thesis is to widen the understanding of the gender pay gap by introducing the factor of sexuality. Same-sex couples have legal rights that are relatively new; how does our understanding of labor division and pay change when more data on queer people emerge? This is achieved by using data from the German Socio-Economic Panel (SOEP) from the year 2017 and making multiple regressions,

The thesis examines what makes a cross-organizational collaboration between a multinational company and an NGO successful, by revieweing what factors play an important role in a project's life cycle, from a corporate perspective. The thesis is based on project management theories within the subjects of international business and cross-organizational teams. A qualitative research strategy with

Financial advisors use paper-based questionnaires to retrieve the information useful to address the clients toward the right financial products and investment mix. In 2004 the European Parliament issued the MiFID (Markets in Financial Instruments Directive) that has the objective to increase competition and investor protection, and levels the playing field for market participants in investment ser

Urbanisation is an inevitable part of globalisation. With the globalised food chain in place to feed the growing number of people living in urban areas. A remedy is often expressed to be urban farming, with local, sustainable production of food. This study presents a preliminary assessment of the dynamics between urban farms and residents in Malmö. Urban farms produce available food for the reside

Accurately reconstructing the rate of movement and extent of eolian dunes over thousands of years is a challenging endeavor. In this paper, we refine the methodology for utilizing lakes and bogs downwind of dune fields as precise recorders of past eolian activity. Sediment cores from two Allegan County lakes and one bog associated with dunes were studied to evaluate the importance of the various s
