Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.

This paper aims to analyze the effect of the American Subprime crisis of 2007 through the perspective ofHaynes Minsky?s model according to Charles Kindleberger. The investigation revolves how the anatomyof a financial crisis develops and how it is applicable to the Subprime crisis. More specific conclusionsare derived from applying Minsky?s model to the three largest American indices; Dow Jones industrialaverage, S&P500 and NASDAQ.To deepen the analysis the Case-Shiller home price indices acts as a second parameter tocompliment Minsky?s perspective with Robert J.

This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go. To analyze the case I use theories of how differences in ethnicity, culture and religion etc. are created and recreated in society in interactions among humans and in the politics - the politics of difference. The politics of difference creates and recreates categories of mobility such as tourists and boat migrants.

In this essay, I want to achieve an accessible and applicable entrance to Alexander Technique as a method for learning to use the body in such a way as to allow emotional expression in music. It is necessary to see the real need of Alexander Technique for the active musician, and therefore important components of music-making will be presented. These components are presented from an Alexander-perspective in order to produce a clear picture of the method of application.The prerequisite for emotional expression in music is musicians and music listeners with the ability to generate, and respond after emotional impressions. Alexander Technique provides an approach to make it easier for musicians, especially guitarists, to express emotions in a performance situation.After years of practice and obtaining musical knowledge and practical skills at the instrument, it is common that muscle tension and ingrained patterns contribute to limited expression. Muscle tensions arising from pressured situations such as auditions, competitions and concerts.

To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.

In Peter Weiss debut Fra?n o? till o? (1947) the ?I? travels from island to island as a castaway. The island here can signify, or work as a synecdoche for exile and the feeling of isolation that exile often induces. But the movement from island to island also implies a restless state: Peter Weiss shifting from painting to writing to filmmaking and theatre, from German to Swedish and then back to German. The years during exile and the years that followed the exile until his breakthrough in Germany with Schatten des ko?rpers des Ku?tchens (1960), Abschied von den Eltern (1961) and Fluchtpunkt (1962), were the formative years of Peter Weiss authorship.

In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

The purpose of this Master?s Degree is to identify and understand different techniques of argumentation in written texts originating from the religious movement Jehovah's Witnesses. The purpose is also to contribute with a theoretical and methodological framework for other scholars. The focal point of the thesis is sexuality and how the authors of the texts try to convince the members to follow the movements' doctrines in this regard. I use a modified version of the well-established grounded theory method.

ABSTRACT Introduction: One of the great difficulties that the nurse anesthetist encounter in their profession is to assess and estimate sleep depth versus signs of pain in the anesthetized patient. Based on a pre-operative appointment and the perioperative monitoring, an assessment of the patient is made. The experience that the nurse anesthetist has can make it easier to understand what subtile signs of the patient depends on. Purpose: With this in mind, the purpose of the pilot study was to try to find out if there are specific signs of pain during anesthesia and if the professional experience played a role. As a subsidiary aim the authors examined whether there were factors in the patient that the nurse anesthetist takes into account in the identification of pain during anesthesia.

Geography, derived from the Greek meaning "the study of the Earth," is a discipline with strong traditions and a rich history. Throughout different historical periods and intellectual movements, however, the focus of the subject has shifted between physical geography and human geography, influenced by scientists, philosophers, and various thinkers who have proposed differing perspectives on what the subject should represent (Couper, 2015). Due to the impact of these actors, geography education in today's Swedish school system is of an interdisciplinary nature, blending elements of both physical and human geography, with components such as environmental issues, sustainable development, digital learning, and fieldwork. However, this task is more complex than it may initially appear. The subject is shaped by various traditions, including national curricula, institutional customs, and the geographical perspectives held by individual teachers.
