PFOS (Perfluoroktansulfonat) har genom sina unika ytaktiva och beständiga egenskaper använts i en mängd olika tillämpningar och blivit ett av jordens mest spridda ämnen. Metallytbehandling, hydrauloljor till flygplan och impregnering av textilier hör till ämnets användningsområden, men mest uppmärksammat är nog tillsatsen till brandsläckningsskum där PFOS är den aktiva beståndsdelen. Upprepade släPFOS (Perfluorooctane sulfonate) has, through its unique surface active and non-reactive properties been used in a range of applications and has become one of the earth’s most wide spread substances. Metal plating, hydraulic fluids and textile repellants are among the chemical’s field of application, but most attention has probably been given the presence in fire-fighting foam, where PFOS constitu

På Älgön, SV Sverige, finns en anortosit-norit intrusion tillhörande Hakefjordenkomplexet. Det finns dessutom två tillhörande enheter; en marginell monzonorit och en centralt belägen ilmenitberikad norit (IRL). I den ilmenitberikade noriten finns även olika sorters aggregat av Fe-Ti oxider. Genom att undersöka Mn-innehållet i ilmenit i alla litologiska enheter var det möjligt att få fram en kronolThe Hakefjorden Complex is an anorthosite-norite intrusion at Älgön, SW Sweden. There are two lithological units associated with it; a marginal monzonorite and a central Ilmenite-Rich Leuconorite (IRL). In the IRL there is a variety of aggregates of Fe-Ti oxides. By investigating Mn-content of ilmenite from all lithological units a chronological order of crystallization could be assessed; oxide ag

Förr i tiden existerade närmare 90 % fler våtmarker på Öland än vad som finns idag. Innan ut-dikningen hade ägt rum fungerade Ölands strandvallar som en barriär för vattnet så det förhindrades att strömma ut mot Östersjön. I huvudsak lutar topografin på Öland österut vilket bidrar till att vattnet automatiskt transporteras från väst mot öst. Genom att dika ut och ta bort delar av de naturliga hindIn the past the need to enhance land use for agricultural purposes resulted in ditching of land and existing beach deposits to reduce wetlands. The ditching resulted in a 90% decrease of wetlands on Öland together with a decrease in groundwater. Before the drainage had started the beach deposits on Öland worked as a barrier that pre-vented the water to run off towards the Baltic Sea. The topograph

Sustainability has become one of the key challenges in the fashion industry, which has been criticized for intense resource use, severe environmental impacts and wasteful business model. There have been a lot of new attempts and initiatives to promote sustainable fashion consumption. Collaborative consumption has been highlighted as one of the alternatives to conventional mass consumption. The ide

The successful construction of any well-functioning structure is dependent on a good understanding of the ground on which it lies. Several methods and techniques have been developed to model subsurface conditions and properties with the purpose of gaining comprehensive knowledge of geological conditions. Seismic refraction presents a geophysical method of subsurface investigation capable of provid

Project has different basis that must be completed to be able to present a finished product. Knowledge of the area and how the projection works will be used in efforts to implement the empirical study. Design assumptions are divided into two groups where some items are specific to a particular product while others are general conditions in all projects. The goal is to identify the conditions and a

Who does what among health care professions? : Medical social workers view on their profession regard to holistic rehabilitation The purpose of the present study is to deepen the knowledge about the work and views of medical social workers working within rehabilitation care. Specifically, their work and views with regard to holistic rehabilitation is focused. Holistic rehabilitation is in the pre

Molecular imprinting technology is a field where polymer technology is utilised to synthesise high affinity particles, much like antibodies. This project has dealt with the imprinting of the neurotransmitter molecules serotonin and histamine. Serotonin polymers were synthesised using methacrylic acid and acrylamide as functional monomers relying on hydrogen bonding for the imprinting effect. None

The study investigates the way education policies affecting primary education provision have been implemented in Kenya to reveal issues derived from their implementation and the impact they have had on parent's choice of school. The study used a qualitative research approach where data was collected through a desk study and semi-structured interviews. The desk study was used for the purpose o

The aim of this master thesis is to investigate ideas in the Swedish debate about e-books in relation to Litteraturutredningen (2012), with focus on ideas that concern access of e-books within the public library. Access is discussed in relation to Buckland’s (1991) six barriers of access of information and Habermas’s (2003) democratic public sphere, as well as the Swedish Library Act (2013:801). I

Syftet med denna uppsats är att öka förståelsen för huvudintressenternas uppfattningar i Sverige kring den obligatoriska byrårotationen med hänsyn till oberoende och revisionskvalitet. Resultatet visar att majoriteten av huvudintressenterna är negativt inställda till den obligatoriska byrårotationen, speciellt i sin slutgiltiga utformning som troligtvis kommer vara utan påverkan på varken det fakt

The international financial crisis has hit southern European countries remarkably hard. As a consequence, governments have introduced economic austerity in order to cope with such a difficult situation. Perhaps most important, left-wing and right-wing parties have contributed to the implementation of these economic policies. Given this unexpected consensus, this thesis examines the Italian case st

Kvark-Gluon-Plasma (QGP) är ett tillstånd av materia som har väldigt hög densitet och en temperatur på 2,000,000,000,000 K. Man tror att universum såg ut såhär precis efter the Big Bang, Den Stora Smällen. Vid detta tillstånd kunde inte hadroner (t.ex. protoner och neutroner) bilda atomkärnor som är grunden till all materia. Detta inträffar på grund av att gluonerna, som binder ihop kvarkarna inutIn high energy heavy ion collisions a new state of matter called quark gluon plasma is produced. An important observable is azimuthal anisotropy flow. Data from the ALICE experiment is used in the search for azimuthal anisotropic flow in pp collisions, at $\sqrt{s_{NN}} = 7$ TeV. p--Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV are used to create a baseline. It is expected to find symmetries in $\De

The essence of the project is based on how wear affects a product. I saw a flaw in the furniture industry that mass-produces products with materials that are negatively affected by wear and tear. These products have a short lifespan and contributes to the ”throw-away” culture where the product is either replaced or thrown away more often than necessary. I wanted to make a living-room table that du

The field of mass evacuation has existed for a long time. Already during the Roman Empire era evacuation problematic was considered. In modern times the field has gained more attention during the last couple of decades, especially for sports grounds and stadiums. Through analysis of some well-known historical crowd disasters and through a literature survey the aim has been to compile the most impo

This report describes the development of a new fixing process when attaching a sensor PCB card to a camera assembly. The thesis focused on cameras which requires calibration to find the optimal position of the sensor PCB card, a process called active alignment. The development process applied for this thesis was derived from the Generic Development Process by Ulrich and Eppinger. Interviewees wit

The aim of this MA thesis is firstly to describe and investigate the theologico-anthropological aspect of the doctrine of deification within contemporary Lutheran theology. Secondly, the aim of the thesis is to propose a theological anthropology that considers the human need and ability to grow, mature and deepen in life and in relationship to oneself, one’s neighbor and God. I argue that this per

The research explores the protections provided for migrant domestic workers who are highly undervalued and often exposed to trafficking, despite comprising an integral part of the labour force worldwide. Saudi Arabia is a focus destination country for the study, as it emerged from among the top destination countries absorbing 61 percent of recorded Ethiopian migrant domestic workers. Despite such

There has been an increasing interest in wastewater treatment in last decades to reduce human footprint. Primarily, anaerobic technology focused on treatment and stabilization of sludge, but now the tendency is to give it a major role in low cost treatment of high/low strength wastewaters, since anaerobic digestion offers energy generation through gas production. Anaerobic membrane bioreactors (A
