Människans hud består av flera olika hudlager som tillsammans bygger upp ett viktigt skydd mot den yttre miljön. Ett populärt sätt för att få aktiva substanser att gå igenom huden är genom att använda sig av så kallade ”cosmeceuticals”, ett mellanting mellan hudvårdsprodukter och läkemedel. Kosmetikaindustrin hävdar att dessa ska ha effekt, dock saknas många studier för att styrka dessa påstående.The skin is the outermost barrier that protects our body by performing several functions that is crucial for our survival. It prevents hazardous microorganisms in the outer environment from entering the body as well as preserving the inside by regulating heat and water loss from the body. Cosmeceuticals are cosmetic products which contains active ingredients that induces drug-like effects. For t

Smältande glaciärer, översvämmade miljonstäder, utrotningshotade isbjörnar, tickande metanbomber, hotande svält och massflykt – det är ingen ljus framtid som väntar oss i klimatkrisens spår. I alla fall om bilden som målas upp i grundskolans läroböcker stämmer. Och vad är då räddningen? Ska man tro böckerna är svaret att våra barn behöver utbildas till klimatsmarta konsumenter. Klimatförändringen The Swedish school has a democratic mandate to prepare students for life in a society where many important decisions need to be made which require an ability to critically examine and evaluate different arguments. This applies particularly to climate change that will bring changes at all levels of society. Textbooks are important for the education provided in schools as they often define the topic

This master thesis has evaluated the possible use of a spray dryer to produce powders suitable for use as inhalants and whether the addition of liposomes to the solution to be spray dried would improve the properties of the powder. The powders created consisted of Lysozyme as model drug, Lactose as filler and stabilizer, and different types of phospholipids to create liposomes using an ethanol inj

Research concerning the challenge of rising sea levels often leave out the importance of landscape and its history. When discussing present and future adaptations to local climate changes, e.g. sea level rise, an understanding of the process that shaped the area that exist today is an important aspect. Here Falsterbonäset is chosen as a case study focussing on three actors the regional planning of

This paper argues that industrialized meat and dairy production create substantial environmental costs that are currently not being reflected by the price paid by consumers. One way of addressing this could be by taxing those products proportional to the environmental damage they cause based on the principle that the polluter should pay. The question is if such a tax could be legally motivated und

Many rural municipalities in Sweden are faced with challenges related to declining population. As people leave the municipality where they grew up in order to pursue university degrees, job opportunities or for other reasons, and a majority might leave for good. However, later in life some of these people return. The aim of this study is to investigate why internal return migrants return to rural

Ett av de främsta målen med Europeiska Unionen är att upprätta en marknad utan inre gränser. På denna marknad garanteras fri rörlighet för bl.a. varor. I EU har medlemsstaterna olika skattesatser på alkohol- och tobaksvaror, vilket skapar ett incitament att utnyttja reglerna om fri rörlighet. Då Sverige har jämförelsevis höga skatter införskaffas alkohol och tobak i länder med lägre skattesatser fOne of the core objectives of the European Union is to establish a single market without internal frontiers. In this market, the free movement of goods, inter alia, is guaranteed. The differences among the EU member states’ excise duty rates on alcohol and tobacco products create incentives to take advantage of the rules ensuring the free circulation. As Sweden has relatively high taxes, alcohol a

Greenland is a former colony of Denmark and today remains part of the Danish Realm. The Greenlandic Reconciliation Commission, which began working in 2014, represents an effort by Greenland to come to terms with its recent history while its government simultaneously pursues the economic growth needed for greater independence from Denmark. The existence of this commission and the debate that has en

Debatten om läxhjälpens utformning blev en symbolfråga som kontextualiserades av samtida politiska händelser och skiftningar i opinionen. Den statliga subventionen Läx-Rut och värnandet om ökad tillväxt stod i konstrast till utlåtanden om bristande likvärdighet i skolan. Finns det någon rättvis väg framåt? Och vilka förslag på utformning av läxhjälpen framfördes? Denna uppsats syftar till att, genThe debate on the design of policy regulating private tutoring in Sweden became a symbolic issue contextualized by contemporary political events and shifts in public opinion. The proposition of a state tax subsidy for private tutoring was opposed by statements arguing for the propositions effects on an equal access to education. Is there a just and plausible way forward? And what were the proposit

Hur stor effekt har den globala uppvärmningen på de Arktiska isarna? Hur stor del av isarna skulle smälta om temperaturerna i Arktis steg med en grad? Med hjälp av Positive Degree Day metoden kan vi svar på dessa frågor. Tänk dig en framtid där havsnivåerna har höjts med flera meter. Om den arktiska isen smälter är detta en framtid vi med största säkerhet kan komma att mötas av. Kommer ditt hus aThe surface mass balance determines the growth or decay of an ice sheet, by taking the difference between accumulation and ablation. In this thesis snow and ice ablation is related to 2m-temperature through the positive degree day method. The positive degree day method takes into account the ablation rate of snow and ice and the number of measurements with temperature above freezing level in order

A processing method is developed to characterize contacts for vertical nanowire structures. The process is based around optical lithography and an organic spacer material in order to facilitate an easily repeatable processing flow. Substrates with MOVPE grown GaSb nanowires are processed into sets of resistor devices. Variation in resistance of the devices is achieved by adding contacts at differen

Att avfyra partiklar med laser: Karakterisering av gasstrålar. Det vanligaste sättet att accelerera partiklar är att skicka runt dem i en cirkulär accelerator, men alternativa sätt kan vara mer praktiska eller billigare, så att forskare kan undvika att göra större och större cirklar för att få mer energi utan i stället skapa mer praktiska experimentuppställningar. En alternativ teknik använder elThe Multi-Terawatt laser at the LLC (Lund Laser Centre) is used to accelerate particles using laser wakefield acceleration. Laser wakefield acceleration is a particle acceleration method that utilizes intense electric fields in plasma created by high intensity laser pulses when passing through gas. A gas nozzle is used to introduce gas in the beamline to produce the plasma needed and the supersoni
