The effects of a change of environment on water kefir’s microbial diversity was studied by splitting up two existing cultures (stem 1 and stem 2) among several households and culturing them for three weeks using the same method and ingredients. Next Generation Sequencing (NGS) was used on the 16S rRNA gene to identify bacterial families, genera and strains. Sphingomonadaceae, Lactobacillaceae, Ace

Collective memory is a psychological and sociological concept. This theory provides a reference for defining the characteristics of a community from the perspective of memory. Further research also shows that its internal connection to culture and community. This has many similarities with user research in product design. By focusing on typical or iconic products, objects, or the interacting proce

In this thesis a framework for finding anomalies in streaming data is proposed. The framework proposed is not necessarily applicable only to problems in anomaly detection, but could be applied to other problems as well. There are three main concepts at play in the framework: (i) Active Learning, a learning algorithm which can query a human specialist for labels of instance such that the model can

The concept of an open air drug market can be defined as a widely known area wherein public trade and use of narcotics is prevalent. This phenomenon contradicts the legislation in place regarding drug use and distribution in Sweden. This case study analyses an open air drug market located in the outskirts of Stockholm. The study specifically reviews the crime prevention methods used by law enforce

For a long time, a method which tunes a robust controller automatically has been researched. In this thesis, a method to estimate processes using a short experiment and low order time delayed models is described. The goal was to achieve a model that could be used for PI- and PID-tuning in an autotuner. Through a simulation study, various experiment designs were tested to find an optimal experiment

The aim of this study is to challenge the Swedish gender equality discourse which has a central focus on gender relations and therefore ignores other power structures. The purpose is also to examine how the public space excludes certain bodies and how the urban planning creates an expectation of heterosexuality, whiteness and doing gender based on cisnormativity. The material used for the analysis

Problem/Bakgrund: entreprenörskap som företeelse har sedan GY 11 infördes gjort entré i gymnasieskolan och blivit en del av gymnasieskolans uppdrag, men begreppet är mångfasetterat och ibland även laddat med känslor och åsikter. Denna mångtydighet ger upphov till olika möjliga tolkningar och därmed konsekvenser för verksamheten och i förlängningen för eleverna. Syfte: syftet med denna uppsats är

I detta kandidatarbete undersöks förutsättningarna för och effekterna av en övergång från produktionsbaserade utsläppsberäkningar till konsumtionsbaserade utsläppsberäkningar inom internationell respektive svensk klimatpolitik. Studien utförs i form av en litteraturstudie. Resultatet visar att det är mycket svårt att avgöra vad effekterna av en övergång till konsumtionsbaserade utsläppsberäkningaThis literature study examines the potential for and effects of a transition from production-based to consumption-based accounting in international and Swedish climate policy, respectively. The result shows that it is very difficult to determine what the effects of such a transition would be, both on the international and Swedish level. Regarding the question of responsibility for emissions, none

The Swedish power grid is actively balanced in order to maintain the nominal frequency of 50 Hz. Today, this is mostly done through flexible power generation. Emerging markets, allowing consuming resources to participate in balancing the grid, have the potential to increase the stability of the grid. This master thesis aimed to investigate the consequences and possibilities of using variable air v

Hydroponics is a method for cultivating plants with their roots suspended in water. This means that the nutrients normally present in the soil have to be supplied artificially, in an appropriate amount. Electrical conductivity can be used to measure the nutrient concentration in a hydroponic solution. This thesis implements a small-scale model of an automated hydroponic farm. The nutrient concentr

Hydropower is simply the largest source of renewable energy in the Nordic countries, where It compose around 90% of power production in Iceland, 70% in Norway, 40% in Sweden and 20% in Finland. Mountainous terrain and abundance in the surface water is a significant contributing factor in hydropower production. Hydropower is also considered more reliable and continuous than other forms of renewable

Inkommande avloppsvatten till ett reningsverk består till största delen av organiskt material som i sin tur kan utgöra en viktig resurskälla för reningsverket. Genom att utnyttja kolet i avloppsvattnet för produktion av metan kan ett reningsverk bli självförsörjande på energi. En nackdel kan dock vara att det lättnedbrytbara organiska materialet, som viktiga reningsprocesser såsom denitrifikation

This paper is initiated to analyze the trade related human rights diplomacy of the European Union (EU) and the United States (US) in Cambodia. In doing so, the thesis is conducted to provide definition and tools of the human right diplomacy that have been utilized by State and Non-State actors at all level. The thesis also examines the human rights situations in Cambodia with the focus on labour r

I vårt stora, komplexa universum är det uppskattat att det finns ungefär två biljoner galaxer. Just vår hemgalax, Vintergatan, ligger mellan de två typiska galaxpopulationerna, i den så kallade "gröna dalen". Galaxer i den gröna dalen är i en fas mellan att aktivt bilda stjärnor och att vara döda. I och med detta så kan vi lära oss mycket om galaxers utveckling genom att studera VintergaOne of the biggest mysteries astronomers wish to unveil is the formation and evolution of galaxies. Properties of our own galaxy, the Milky Way, can provide great insight into these. The star formation rate (SFR) and whether it varies with distance from the galactic centre (GC), is one of these properties. Studies indicate that the SFR is higher in the bulge region than in the local thick disk of

Resultatet av #metoo-uppropen visar att sexuella trakasserier och sexuellt våld är ett omfattande samhällsproblem, som drabbar kvinnor i högre utsträckning än män. Den här studien går baserat på det ut på att kartlägga attitydskillnader mellan män och kvinnor, relaterat till sexuellt våld och sexuella trakasserier. Studien redogör för troliga bakomliggande orsaker till könsrelaterat våld och under

Problem/Bakgrund ME/CFS har fått medial uppmärksamhet på senare år. Bland annat har olika dödsfall och självmord som relateras till ME/CFS uppmärksammats. Även ME/CFS drabbades sociala och ekonomiska situation har uppmärksammats, och av vissa beskrivits som en orsak till dödsfallen och självmorden. Mot bakgrund av att ME/CFS är ett aktuellt samhällsfenomen med stora konsekvenser för de drabbade, m

Mycoplasma bovis (M. bovis) infections are difficult to diagnose and treat, causing severe economic losses to farms with infected cows. Eurofins Milk Testing Sweden AB screens cow’s milk using qPCR (quantitative Polymerase Chain Reaction) to detect M. bovis infections. Five performance characteristics were chosen to evaluate if ELISA (Enzyme-Linked Immunosorbent Assay) could replace the current sc

Hur kan organogen jordbruksmark återvätas för att minska växthusgasutsläppen? Våtmarker och sjöar dikades under 1800-talet ut och omvandlades till jordbruksmark för att kunna mätta en snabbt växande befolkning i Sverige. Men växthusgasutsläppen från dessa dikade jordar bidrar idag till ett stort problem som hotar både liv och försörjning: klimatförändringen. I Lunds kommun kan dikad jordbruksmarkDrained organic soils are a big source of greenhouse gas (GHG) emissions. Many of these soils have, historically, been drained to increase the share of agricultural land. In Sweden, they emit around 3.4 million tonnes CO2 and 0.9 million tonnes CO2eq of N2O per year. This thesis was written on request of City of Lund, to gain a better understanding of the contribution of cultivated organic soils t

The study analyses postfeminism in an organisational context from a critical feminist perspective by exploring the contemporary perceptions of gender and gender equality in a female student career network. Furthermore, the study aims to investigate how these perceptions are projected and how they relate to organisational values, principles and processes of the organisation. Hence, How does postfem

Environmental damage during armed conflicts can create significant risks to the civilian population. It is associated with acute and long-term threats to public health and livelihoods, limited access to such resources as water. On top of direct impact (e.g. physical destruction), secondary impact (e.g. resulting from coping strategies of populations), armed conflicts also weaken environmental gove
