This paper aims to look at the positive and negative aspects of the biodegradable material poly(lactic) acid (PLA) compared to controversial plastics. This is done through a literature study. PLA is a biobased and biodegradable plastic that are used in for example medicine and packaging materials around the world. The results from this study show that the biodegradation of the material is not that
In the context of continuous biodiversity loss connected to land-use changes and urban development, different methods such as biodiversity offsetting with the underlying aim of achieving “No Net Loss” (NNL) of biodiversity has been proposed. Compensation according to the mitigation hierarchy is one type of biodiversity offsetting which currently is being used in the municipality of Helsingborg, Sw
Detta examensarbete ämnar att undersöka om och hur man skulle bygga en modell för att kunna beräkna utsläppen av växthusgaser vid förändringar av transmissionskapacitet. Arbetet avhandlar hur det nuvarande elsystemet är uppbyggt och påverkan på utsläppen av växthusgaser ifrån ökad produktion av förnyelsebar elproduktion och ökad transmission av elektricitet. Utifrån att studera vind- och lastdataIn the light of the importance of climate change and the emissions that have induced it, the ability to calculate the effect on emissions by changing transmission capacity is vital. A model to perform such indicative calculations is developed in this thesis. After researching how the current electricity system is organised, the effects on GHG emissions that are expected from increased renewable el
Yearly in Sweden, large quantities of material lose much of their monetary value due to poor material recycling efficiency. In the common linear economy, material recycling is not prioritized, however within a circular economy recycling is a vital part. PolyPlank has with their own polyplank material built their company based on the principles of the circular economy. Their polyplank material is a
The aim of this study is to understand how the emotional aspect of employee identification evolves through daily interaction in multicultural organizations. Applying a process model of individual identification, this research aims to offer an employee perspective, to uncover the communication challenges employees face and how they make sense of the interaction at work relating to the feeling of be
Bakterier är något som finns överallt. En del goda, som gynnar vår tarmflora, medan en del är onda och kan ge oss infektioner och matförgiftningar vid fel hantering. Just för RTE-sallader (ready-to-eat) är det extra viktigt att rutiner följs eftersom de inte värmebehandlas. Faktorerna som påverkar bakteriernas tillväxt är tillgång till näring, vatten, pH, temperatur, salt, socker och syre. Detta a
The determination of the built-up area of a refugee camp is an important task as it can be used for estimating the population. While high resolution satellite imagery can be costly, since 2015 Sentinel-2 data has become available through the European Space Agency. Sentinel-2 offers 10 m resolution images with frequents updates. In this paper three methodologies are compared for the purpose of esti
Sustained economic growth is essential for developing countries in order to develop. Resource dependent countries face difficulties creating sustained growth as most suffer from a resource curse. Building on previous literature, this research aims at exploring the resource curse literature, with a focus on the time period 1995-2016, which includes the commodity boom, for countries located in Sub-S
The purpose of this paper is to examine if it is possible to profitably implement a market neutral trading strategy, so-called "pairs trading", on three different Swedish investment companies. It can be concluded that applying a pairs trading strategy on [these three] Swedish investment companies and their underlying listed assets has the potential to beat the market Sharpe ratio. Howeve
In most projects, there is a need to visualize geographic data in a map and in most cases, this is done in an interactive map on a computer, tablet or mobile phone. To be able to publish geographic data on the web, several components are needed. These components are in many cases purchased with a user license from a company that provides the customer with support and other user instructions. An al
Almost half the Danish population report that they have undertaken action(s) with the main purpose to lower their personal greenhouse gas emissions within the last three years. It has become “in” to be green, yet certain practices are perceived as “better” than others although they do not necessarily result in a lowered environmental impact. Why is that? Data from seven semi-structured interviews
In the last two decades, dominant business models in the economy have turned to aggregating the resources of people to provide services to consumers through a platform. Airbnb, Uber, and Amazon are a few examples in sharing economy services (SES) business employing this model. Blockchain is set to disrupt these giants by facilitating direct access between users and service providers in a secure an
Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. Moreover, the architectural design of the façade assemblies further complicates the evaluation of the fire safety strategies. The energy reduction requirement
Krita-paleogen-gränsen har länge varit central i diskussioner mellan forskare runt om i världen, då den markerar/sammanfaller med utdöendet av 75% av jordens arter till följd av ett enormt asteriodnedslag på Chicxulúbhalvön i Mexiko. Gränsintervallet är vida utbrett i sedimentära lagerföljder som bildades under denna tid, och kan identifieras genom sina unika kemiska egenskaper och karakteristiskaThe Cretaceous-Paleogene boundary has long been a center of discussion amongst scientists as it marks the extinction of 75% of all species on Earth. This mass extinction event was probably caused by an enormous asteroid impact event in what is now Mexico. The boundary interval is easily identified in the sedimentary geological record because of its unique chemical properties as well as its charact
Salafism is a fundamentalist belief of Islam and its believers strive to live like their forefathers did. In Sweden, the group aim for peaceful segregation and isolation among their believers, rejects modernity and avoid socialisation with Western society and its inhabitants. Salafism has recently acquired more attention due to the terrorist organisation ISIS which justifies their actions based on
Throughout history to this day, the food industry has been facing numerous food contamination incidents. Globalization and an increasing complexity of the food supply chain creates the need for high trust in the information exchanged, therefore there is a lot of focus on food traceability. While there have been improvements to food traceability by the advancements in information systems, transpare
Sedan några år tillbaka finns det förstelärare i skolan. Syftet med studien är att undersöka hur förstelärare och andra ämneslärare i matematik tänker om förstelärares uppdrag att leda utvecklingen av undervisningen i det aktuella ämnet. Vid vår undersökning har vi valt att använda oss av kvalitativ intervjumetod. Studien har en kvalitativ forskningsdesign. Fenomenologi används som forskningsstrat
This thesis investigates the social dynamics of the Chin refugee group which currently faces great challenges in Malaysia, the host country. Modes of organisation and coping mechanisms are examined in relation to the specific legal and socio-political context. The theoretical concept of “diaspora” is used to make sense of processes of identity (re)construction and collective action. In addition, f
Motivation och meningsfullhet är det som driver oss framåt. Genom att ställa klassiska teorier mot resultat som samlats in via enkätintervjuer var syftet med denna studie att undersöka hur ett 20 tal personer som är aktiva i arbetslivet känner en meningsfullhet och vilka faktorer som gör att de upplever motivation i sitt arbete. För datainsamling av det empiriska materialet genomfördes enkätinterv
The aim of this study is to see how big the estimated number of unrecorded cases in Sweden are when it comes to reporting sexual molestation and to see if the court sees the victim as an ideal victim. If so, it is in our interest to investigate if the ideal victim can be associated with the number of unrecorded cases. The cases from the court in Malmö has been coded, placed into charts and analyse
