Extraktion är en separationsteknik som används för att avskilja önskade ämnen från en blandning. Syftet är att utvärdera hur man kan påverka extraktionen av läkemedel genom vaginala ringar. De vaginala ringarna som användes till studien är tillverkade av materialet Etylenvinylacetat (EVA) blandat med läkemedel. Därefter har ringarna blivit inkapslade av filmer som endast består av EVA-material. MThe aim of this thesis was to evaluate influencing parameters of extraction through polymers and find effective extraction methods. A second purpose was to compare differences and similarities of various polymers consisting of Ethylene Vinyl Acetate (EVA) when extracted with identical parameters. Vaginal rings made of EVA which were loaded with active substance were used for the study. The rings a

Finland’s social security spending has been increasing rapidly over the past four decades, and is expected to continue increasing in the decades to come. The increase has been largely driven by population ageing resulting in increased old-age spending. Finland’s social security system is however more than just old-age social security; which warrants a more detailed analysis of the different types

Problemställning: Vad händer vid låga relativa luftfuktighetsnivåer och vilka nivåer bör man åstadkomma? Syfte: Skapa en förståelse av vad som sker vid låga relativa luftfuktighetsnivåer och hur människan påverkas vid dessa nivåer. Vidare ska det även skapas en förståelse för vid vilka RF-nivåer befuktning eventuellt kan vara en lämplig åtgärd med beaktande av de fuktrelaterade risker som kan uppProblem: What happens at low relative humidity levels and what levels should be achieved? Purpose: Create an understanding of what happens at low relative humidity levels and how humans are affected at these levels. Furthermore, an understanding of which RH-levels humidification may be an appropriate measure considering the moisture related risks that may occur. Method: The thesis is a literatur

Flow cytometry (FCM) is a powerful method for analysing cell characteristics, for cell quantification and for separation of different species. An automated FCM processing pipeline for lactic acid bacteria (LAB) was developed, and an analytical pipeline for co-cultures of LAB and Saccharomyces cerevisiae was designed. Data processing pipelines for Limosilactobacillus reuteri DSM 17938 sampled over

There has been a substantial increase in demand for textile and clothing with huge implications for post-consumer textile waste management systems. The current ‘buy-and-throw-away’ culture has led to larger quantities of textile and clothing ending up in landfills and incineration than before. This has become an increasing problem in the world and the linear way of operating is no longer sustainab

Brazilian jeitinho is a widespread informal practice that seeks to solve a problem without necessarily considering the rules. The aim of this thesis is to investigate how individuals who relate in different ways with state laws perceive this practice. In this context of informality, Ehlich's living law was applied to analyse the jeitinho as a Brazilian type of norm of conduct. Hertogh's le

Travel on railway in Sweden has increased steadily over the past three decades and there are today twice as many passengers travelling by train as there were 30 years ago. The increasing awareness of environmental issues with other methods of transportation is likely to favour railway travel, and so the number of passengers is expected to continue to rise. As the number of passengers increase, so

Den svenska byggnationen och utbudet av bostäder har länge varit homogent då bostäder utformats på samma sätt under lång tid. Det byggs för få bostäder samtidigt som konkurrensen är låg mellan bostadsutvecklarna vilket är en faktor till höga bostadspriser på marknaden. Hushålls möjlighet att ta sig in på marknaden har påverkats av infört bolånetak och striktare amorteringskrav. Det har nyligen börThe Swedish construction and supply of housing has for a long time been homogeneous because the housing has been designed in the same way over decades. The competition between housing developers is low and at the same time not enough housing has been built, which is a contributing factor of high housing prices on the market. Households’ ability to enter the market has been affected by the introduc

The aim with this Master’s Thesis work was to conduct research about different available authenticators, as well as implementing a multi-factor authenticator into the currently used login-application. The research included biometric authentication technologies, and investigation of how to implement these to create a highly secure and customizable multi-factor authentication for My Axis-accounts fo

Syfte: Syftet med denna uppsats är att bidra med ytterligare kunskap inom området kulturförändringar i organisationer, närmare bestämt öka förståelsen kring planerade toppstyrda kulturförändringar. Syftet är mer specifikt att bidra med en insikt kring hjälpande och stjälpande faktorer. Forskningsfrågor: - Vad har Svenska Gymnastikförbundet för ambition med kulturförändringen? - Hur förhåller sig

This thesis examines queerness in the poetry of John Donne by re-examining same-gender desire in his poetry, proposing metaphysical poetry as having points of similarity with queering strategies and queer theory, and exploring contextual and historical tensions within and around Donne’s body of works. The thesis closely analyses poems which have previously been discussed as queer, such as “Sapho t

The objective of this study was to quantify swelling in gasket materials to better predict the gaskets life span in heat exchangers. Alfa Laval produces plate heat exchangers, which are a common unit within the process industry. There are different types of plate heat exchangers, and one type is sealed with gaskets. Two common types of rubber used as gasket materials are EPDM and NBR which are stu

The objective of this thesis is to analyze how typhoon response operations in the Philippines were impacted by the COVID-19 pandemic. This multi-hazard scenario is not a singular case, many places around the world have been exposed to similar dilemmas of natural hazards occurring simultaneously as the pandemic. This study was carried out with the intention of better understanding the interplay of

An adaptive memory system has to support both the encoding of individual episodes as well as generalization and inference across several episodes. The latter of these two goals is achieved by memory integration in which a memory representation is updated to accommodate new information. However, the circumstances leading to either separate encoding or generalization are still unknown. Building on l

Nationella End of Waste-kriterier – ett verktyg för ökad återvinning av bygg- och rivningsavfall För att skapa en hållbar utveckling är det viktigt att skapa giftfria cirkulära materialströmmar, där bygg- och rivningsavfall inte är något undantag. Nationella End of Waste-kriterier (EoW-kriterier) för specifika materialströmmar är ett verktyg som gör produkter utav avfall. Genom detta arbete visasThis study contributes with knowledge of effective strategies in the conversion towards a circular economy. Since construction and demolition waste (CDW) is one of the largest waste streams in the EU, there is a need to recycle the material. End of Waste criteria (EoW criteria), which specify when certain waste ceases to be waste, is a possible way of increasing the recycling rates. This study com

A global surge in the number of regional trade agreements has taken place since the 1990s. Their impact on the trade patterns and development of participating countries has been a frequent topic of debate. In this study I analyse the impact of joining a regional trade on the trade patterns of African countries. I find that on average regional trade agreements increase the intra-regional exports be

This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. Four different form-factor mod- els are used to compute corrections: vector-meson dominance, lowest-meson dominance, tree-level, and two-hadron saturation. The experi

This study examines the implementation of circular economy principles in a company operating in a developing country. Focus is put on the start-up phase of the company, where we seek to understand the entrepreneurial motive behind implementing circular, sustainable practices in the infant stage of the company. Furthermore, the methods used to construct a circular, sustainable business model are in
