Kemi och kemikalier är något som är inblandat i vårt dagliga liv mycket mer än vi alla tror. När man hör ordet ”kemikalie”, tänker de flesta på något med ett långt konstigt namn, något onaturligt eller farligt. Men allt är kemikalier och bara för att något har ett svårt namn, betyder det inte att det är farligt. Ett exempel är (2R,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal, eller i folkmun ”glukos” sCarbohydrates are found everywhere. They are the main component in the macromolecules glycosaminoglycans, chains of carbohydrates that make up our cartilage but also play important roles in cancer cell proliferation. Xylose is a carbohydrate which initiates the biosynthesis of these chains by acting as a substrate for the enzyme β4GalT7. Some of these GAG chains become toxic for certain cells. The

Introduction: This study evaluated lipid identification using mass spectrometry. Background: Three main modes of acquisition are used in mass spectrometry of lipids; data-independent acquisition (DIA), data-dependent acquisition (DDA) and targeted acquisition. DIA is the most including one, yielding a complete but complex data set, while targeted is the least including one, basing acquisition on

Samhällets och arbetsmarknadens förändring de senaste decennierna har lett till att vissa yrkesgrupper har blivit mycket attraktiva på arbetsmarknaden. Organisationer som är i behov av dessa bristyrken tävlar om att få anställa dem, och krav på anställningserbjudandet blir allt större. En viktig faktor i konkurrensen är organisationens arbetsgivarvarumärke. Undersökningen tittar på en särskilt att

Multiculturalism theories and entrepreneurship research, in terms of personality, shows significant similarities indicating that multicultural individuals could possess essential skills to survive in entrepreneurial environments. However, these two streams of research have yet to be integrated. The aim of this research is to explore and understand how multiculturals behave in and influence their n

The focus of this study was exploring the product development process of a dairy- based drink which was co-created within a public-private partnership approach for Base of Pyramid (BoP) consumers in Zambia. An exploratory case-study research design was selected. Through interviews, documentation and observations, the steps of the product development process were mapped and the contributions from t

The pharmaceutical industry uses animal models in a variety of settings including safety, pharmacodynamic modelling and efficacy. Conventionally, a frequentist design of standard animal experiments of human asthma replication includes repeatedly running treatment groups with the exact layout, focusing on effect size rather than capturing historical data of animal responses on compounds of interest

In this thesis, a magnetic study of two dierent arrangements of Fe3O4 nanoparticles is presented. The nanoparticles are generated using an aerosol technique and guided onto a substrate. The rst sample was produced by guiding the nanoparticles onto the substrate using an electric eld, resulting in large clusters of randomly oriented Nanoparticle (NP). The second sample was created by also applying

Det är väl känt att kolmonoxid (CO) är en giftig och hälsofarlig gas som är luktlös, färglös och smaklös vilket gör den svår att detektera utan analytisk utrustning. Men under senaste åren så har forskning bevisat att i små doser så kan kolmonoxid användas som en terapeutisk substans för att lindra malaria, cancer, lung-, hjärt- och kärlsjukdomar men även reducera mängden inflammatoriska substanseIt is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is th

Recently, the urbanization in China caused much social problem in China, and one of the distinctive features of urbanization is the increasing population density. This thesis aims to discover the relationship between population density and fertility in China by choosing Xinjiang region as an example, other determinants of fertility in Xinjiang region were also examined, such as average income, emp

Have you ever wondered how we can reduce food waste and at the same time provide a more sustainable and eco-friendly environment to all of us? One of the United Nations goals is to bring by 2030 more responsible consumption and production to the environment. Industries are paying annually for solid waste disposal up to 16,000€ and at the same time, the most preferred way to dispose it is through l

A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. Characterizationof these nanowire arrays on their native substrates provided reliable and nondisruptivemeasurements of thousands of nanowires simultaneously

In the last decade, there has been a substantial shift from actively managed funds to funds with passive investment strategies. This shift was also observed by Shleifer (1986), who identified that passive investment funds began to significantly increase their ownership of the S&P 500 in the period between 1975 and 1983. As the ownership of the stock market increased as the number of index fund

Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. They affect plant species composition by trampling, removal of foliage and by fertilization through dung and urine. These alterations in species compositio

Traditionellt sett har höga byggnader uppförts med stomme av antingen betong eller stål. Trä som byggnadsmaterial har däremot använts till största del i mindre hus. I takt med att byggnadstekniker har utvecklats och byggnadssektorn letar efter mer miljövänliga alternativ börjar även höga träkonstruktioner bli mer eftertraktat. Ett problem med dessa konstruktioner är att trä är ett vekare och lättaTraditionally, high buildings have been built with either concrete or steel. Wood as a building material, however, has mostly been used in smaller buildings. As building techniques have been developed and the construction sector are looking for more eco-friendly alternatives high wooden structures are more sought-after. One problem with these designs is that wood is a weaker and lighter materials

Bakterier som lever i vatten brukar ta sig fram med hjälp av långa trådliknande utskott,så kallade flageller. Denna simteknik är väldigt annourlunda jämfört med det vi oftast ser i vår omvärld, att simma med fenor eller åror är nämligen inte särskilt effektivt för bakterier. Detta har att göra med vattnets radikalt annourlunda hydrodynamiska egenskaper på mikroskalan. Man brukar tala om det så kalMicroswimmer is a term that denotes small selfpropelling agents, such as bacteria, algea or artificial robots. Depending on the flow field they set up they can be categorized into two classes: pushers (e.g. E. coli ) and pullers (e.g C. reinhardtii ). The occurrence of jets, eddies and flocking have been observed in systems of dens pusher suspension. This phenomenon is called active turbulence. Th
