Mikroföroreningar är små molekyler som är restprodukter från t.ex. läkemedel, hormoner, kosmetika samt mikroplaster. Då majoriteten av dessa inte renas i våra av- loppsreningsverk har mikroföroreningarna börjat ackumuleras i vattendrag och dess negativa inverkan på vattenlevande djur har börjat uppmärksammas. En av metoderna för att ta hand om och avskilja mikroföroreningarna i reningsprocessen äThis thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. The effluent has been analyzed for total phosphorus (TP), total suspended solids (T

This is an ethnographic study on how refugees and policies on asylum and immigration was debated on Facebook in Sweden during the so called ‘refugee crisis’. This study analysed the relation between the Facebook debate, and the way news media framed the ‘refugee crisis’ during three months in which Swedish asylum policy changed drastically: September 2015, November 2015 and January 2016. In Septem

Nima is a distressed neighbourhood located north of central Accra, the capital city of Ghana in West Africa. Nima is an extremely dense community, where land is very scarce. Single floor, clay built compound houses occupy the entire neighbourhood. Spatial planning is lacking, infrastructure is limited and overcrowding proposes a severe problem. Nima, a neighbourhood which is a direct result of rap

This study investigated the impact of a national palliative care policy introduced in 2013. The hypothesis was that end‑of‑life and palliative care policy shape healthcare services, which in turn influence service utilisation and ultimately place of death for people dying from cancer. The aim was to identify longitudinal trends in place of death for people with cancer in Sweden. A population‑level

Populärvetenskaplig sammanfattning: Kunskap om mängden kol som växter tar upp i från atmosfären är i dag en viktig frågeställning inom naturvetenskaplig forskning. Resultaten av sådan forskning kan bl.a. användas vid internationella konventioner som t.ex. Kyoto avtalet. I denna studie har jord prover från semi-arida agro-ekosystem i Sudan statistiskt analyserats för att se om skillnaden i organiskSummary: It is well documented that atmospheric carbon dioxide (CO2) is increasing globally. Many scientific studies also show that increased CO2 in the atmosphere may raise the mean global temperature and disturb climates in unforeseen ways. The Kyoto Protocol is a framework aiming for an international collaboration for the reduction of atmospheric greenhouse gases (GHG), of which CO2 is one of t

The Swedish public library was founded in the years when the society in Sweden went from being a society of agriculture to industrialism. Modernism was sweeping over the country, everything was possible, which influenced the new society that was built. Now Sweden was going to be a true democracy with responsible and empathic citizens. One of the main tools in this process was to educate people, to

Avancerade 3D skrivare är en etablerad teknologi och används inom många olika områden. Nu finns det möjligheter att 3D printa hus, proteser och även viss mat kan 3D printas. Detta visar att denna typ av 3D teknologi har en oerhörd bredd och potential. På senare tid har enklare 3D skrivare utvecklats för kommersiellt bruk. Detta har gjort att teknologin blivit mer lättillgänglig för allmänheten ochIntroduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications. This master thesis will inves- tigate if there is a possibility to use a FDM 3D printer to construct an optically stimu

This paper studies the ideas of two actors in the Scandinavian field of Information Systems development. It analyzes the writings of Börje Langefors and Bo Dahlbom in the 1980s and 1990s, and focuses on their collaboration resulting in the publication of Langefors’ Essays on Infology. Langefors was at that time honored as the founder of the information systems discipline in Scandinavia, but had al

Konstgjord grundvattenbildning är en viktig teknik i vattenhushållningssammanhang och är idag en av de vanligaste och mest utbredda metoderna i världen för att öka vår grundvattenkapacitet. I många länder har den här tekniken använts under lång tid medan den i andra är i framåtskridande. Tekniken har använts i Europa sedan början av 1900-talet och är fortfarande en vanlig metod för grundvattenförsArtificial groundwater recharge is an important technology in water resources management and is nowadays one of the most common and rapidly spread world wide methods for increasing groundwater capacity. In many countries this technique has been employed for a long time, however in the others it is in progress. It has been used in Europe since the early 1900s, and is still a popular method municipa

Popular Abstract in Swedish Melanin är ett pigment som finns i många olika slags vävnader. I hud och hår finns två slags melanin, pheomelanin som är typiskt för rödhåriga personer och eumelanin som finns i större mängd i mörkt hår och hud. Konstaterad korrelation mellan hudcancer och solexponering motiverar forskarna att förstå mer om melanin och dess växelverkan med UV-ljus. Man vet att rödhårigaMelanin is an epidermal pigment commonly known to give darker skin coloration under sun exposure. It is also present in the hair, eyes, inner ear and brain. The first function of epidermis melanin is believed to be photoprotective against harmful ultraviolet (UV) light, but the recent increase of skin cancer correlated to an increase of sun exposure questions the properties of melanin. Its presenc

The conference series European Conference on Scientific Publishing in Biomedicine and Medicine (ECSP) was originated at the Faculty of Medicine, Lund University, Sweden and was for the first time launched in Lund in 2006. The mission to be highly relevant for researchers was retained at the second meeting, hosted by University of Oslo, Library of Medicine and Health Sciences. The meeting focused o

Based on articles published 1990-2004 in 21 LIS journals, a set of co-citation analyses were performed to study changes in research fronts over the last 15 years, where LIS is at now; and to discuss where it is heading. To study research fronts, here defined as current and influential co-cited papers, a citations among documents methodology was applied; and to study changes, the analyses were time

Background: Possibilities of detecting oxygen - both in its free form, as gas in the lungs, and in its bound form, as oxygenated hemoglobin - have been explored in this thesis. Perfusion and oxygenation of vital organs (e.g., heart, brain and kidneys) may be severely compromised in critical illness or major trauma, which is why blood is rapidly diverted to those organs to improve chances of surviv
