Determining fatty acid composition within different lipid classes is a time-consuming process. Generally, normal phase chromatography is used to separate lipids by lipid class, based on differences in polarity. Fractions of this separation are then collected and derivatized into fatty acid methyl esters (FAMES), followed by analysis with gas chromatography and flame ionization detection (GC-FID).

Uppsatsen undersöker hur femininitet förhandlas i digitala feministiska miljöer genom en fallstudie av Redditforumet r/notliketheothergirls. På forumet, som har en påstådd feministisk prägel, publicerar redditanvändare en grupp uppmärksammade memes som benämns notlikeothergirls-memes i syfte att diskutera och kritisera dessa. Memesen är utformade som en jämförelse mellan en själv, me, och andra kv

Syftet med studien är att undersöka huruvida det finns ett samband mellan andel kvinnor i bolagsstyrelser och finansiell prestation hos börsnoterade bolag i Sverige.The study aims to investigate if there is a relationship between fraction of women in the board and financial performance for companies listed on Nasdaq OMX Stockholm.

Natural events that happen more rarely have historically been more difficult to study and continue to require different methods. For example, rare occurrences of natural disasters and weather events can have return periods of thousands of years but because of their large impact are very important to study. In addition to being used to study the changing climate, climate models have the advantage o

Today's blockchain applications have been inherently created by and for users who understand the blockchain technology. To improve mass adoption of blockchain solutions, the user experience must improve, and the attention must move to users not familiar with the underlying technology. This dissertation starts with reviewing the main concepts of blockchain technology and examining the UX of dif

I mitt yrkesliv har jag varit verksam i ett antal olika organisationer inom samma bransch, både som anställd och på mellanchefsnivå. Det har fått mig att fundera på dels hur företag som till synes är ganska lika med samma verksamhet och målsättning ändå kan vara så olika? I denna uppsats tar jag utgångspunkt i hur det är att vara mellanchef. Att vara mellanchef innebär att vara den person som befi

Syfte: Uppsatsen syfte är uppdelat i två nivåer. Det grundläggande syftet är att studera om metoo-rörelsen har satt spår i svensk och brittisk hållbarhetsredovisning. Uppsatsens mer övergripande syfte är att, med hjälp av teori om nationell kultur och institutionell teori, undersöka vilken relation uppmärksammade samhällsfenomen har till redovisningspraktik. Metod: Uppsatsen tillvägagångssätt innePurpose: Fundamentally the purpose is to study if the metoo-movement has affected sustainability accounting in Sweden and in the UK. Using national culture and institutional theories, the more general purpose of examining the relationship between social phenomenon and accounting is carried out. Methodology: The approach consists of three stages. Firstly, a quantitative content analysis of the dat

Som verksam barbershopdirigent och sångcoach har jag ett stort intresse för att bredda min kunskap om hur jag kan arbeta med intonation i grupp. Jag vill också ta reda på vilka tankar dirigenterna gör sig omkring hur de skapar förståelse bland körsångarna för det gemensamma arbetet. Denna studie undersöker några barbershopdirigenters syn på intonation, samt hur de arbetar med intonation i kör. StuAs an active barbershop director and vocal coach I have a great interest in broadening my knowledge about working with groups and intonation and to find out how other directors reason around creating an understanding for the chorus work among the chorus members. This study examins a few barbershop directors' views on intonation and how they work with intonation with their choruses. The study a

Recent developments in the field of optical clocks and quantum information have fueled the necessity for both fiber phase noise cancellation and laser stabilisation. The Quantum Information group at Lund University is conducting research on quantum computation experiments based on rare earth ion doped crystals and also application of slow light effects induced by spectral hole burning in these rar

This essay examined the connection between human experience and the interpretation of literature. The aims were to find out how expectations, experiences and knowledge colour our interpretations, and to get an understanding of how the meaning of literature is created and mirrored by the reader. Previous studies have been made on reader-response theory, but studies that focus on teacher-student rel

This research explores the promotional discourses the neoliberal experts and politicians use to legitimise the stipend shortages to the students, whose interests this policy contradicts. The thesis argues that the proponents of the reform established the dialogue with the opposition in order to avoid the large-scale protests against the policy. The study suggests that the policy promotion opens up

Heltäckande riskbedömning av kontaktallergiframkallande ämnen med cellbaserade metoden GARD®skin Metoden GARD®skin identifierar kontaktallergiframkallande ämnen med hög noggrannhet. Genom att sätta koncentrationen mot svarsvärdet av GARD®skin i en dos-responskurva kan metoden potentiellt utvecklas för att även klassificera styrkan och effektiviteten av ämnens förmåga att orsaka kontaktallergi. Allergic contacts dermatitis is a major health problem in the world and the disease is caused by a type IV hypersensitivity to a small chemical called a hapten. These substances are common in cosmetics, perfumes, pharmaceuticals and house-hold products, and risk factors include both inherent factors and frequent or high exposure. Hazard assessment and potency classification of sensitizers are ther

Structural transformation is a broad concept that has been widely argued to be of great importance for long-run economic growth. A common historical pattern highlights the labour shift out of agriculture towards manufacturing and industry sectors as the main characteristic of structural transformation. Today, large parts of the world are industrialized, as a result of a successful structural chang

We study the key properties of the quantum SU(2) Yang-Mills ground state and its possible role in the early Universe, in particular, as a driver of Cosmic Inflation. Using the effective action approach and separating the Yang-Mills field potential into homogeneous (condensate) and inhomogeneous (fluctuations) components, we reproduce the conformal-time solutions for the two different types of the

I detta examensarbete, som skrivits i samarbete med Svenska Turistföreningen (STF), beräknas och utvärderas de växthusgasutsläpp som driften av föreningens fjällstugor, belägna i väglöst land, ger upphov till. Beräkningarna baseras på de fyra fjällstugorna Alesjaure, Sälka, Kårsavagge och Nallo. I studien beräknas det att en gästnatt, det vill säga en övernattning av en person, på en av de studeraThis master thesis was written in collaboration with the Swedish Tourist Association and evaluates the yearly greenhouse gas emissions caused by the management of the association’s mountain huts. The hut’s are situated in roadless land. The calculations are based on the four mountain huts Alesjaure, Sälka, Kårsavagge and Nallo. An overnight stay at one of the studied mountain huts give rise to on
