Validering av metoder för analys av Cu, Fe och Na i processvatten med AAS-grafitugn

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

Faderskap i ett nytt land. En kvalitativ studie om förändrade förutsättningar för faderskap.

This thesis focuses on immigrant fathers and the specific situation they face arriving in Sweden. The purpose of this study is to examine various systemic obstacles and eventual possibilities these fathers may encounter in the new country and how they affect their fatherhood. The paper is based on four interviews, with three men and one woman, who work with immigrant fathers partly in parenting educational programs. The informants? professional background varies.

Från väpnad oppositionsgrupp till politiskt parti- En komparativ studie om transformeringen och institutionaliseringen av RENAMO, FRELIMO och SWAPO i Moçambique och Namibia

This thesis explores and compares the former armed opposition groups; Mozambique National Resistance (RENAMO), Front for the Liberation of Mozambique (FRELIMO) and South West Africa People's Organization (SWAPO) transformation processes into political parties. The first question addressed is; What factors determines the ability of these armed opposition groups to transform into political parties after armed conflict? The question is addressed through four structural and organizational factors; international involvement, the organizations ideology and identity, their ability to change inter-elite relationships and their ability to change collective incentive strategies. The second question addressed is if the transformations process can affect the parties? degree of institutionalization? The degree of institutionalization is examined through the party's adaptility, complexity, autonomy and coherence.

Mänsklig säkerhet i Sudan- För vem och mot vad?

The concept of security is a contested one. The United Nations definition in UNDPs Development report of 1994 is the most authoritive and commonly cited. The civil war in Sudan has led to 2 million deaths and over 5.5 million refugees. In a resolution from 2005, the UN decided that the war in Sudan was a threat to international security and peace. The 10th of January UN decided that a peace commission ought to be send with 10 000 military and civil men including 700 policemen.The main purpose of this thesis is to improve our knowledge of those factors which can cause an increased risk of conflict within a state, and how that can affect the social conditions for individuals.

A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT

Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls. Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem. The diabetic pigs were insulin treated and responded well.

Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala

The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Tyskland och skuldfrågan : En historiografisk och komparativ studie av svensk och tysk Förintelsefacklitteratur, 1996-2010

The present study is primarily of historiographical type, but also uses comparative method and qualitative text analysis. It mainly aims to explore how Germany and the issue of guilt have been portrayed in Swedish and German nonfiction literature (excluding teaching materials) during the years 1996-2010, in the context of the Holocaust, but also makes a comparison between these two countries' depictions. Furthermore, it also examines whether it is possible to link the various depictions to specific theories, in this case determinism together with the actor and structural perspectives, as well as to other potential factors such as the authors' personal connections to the Holocaust or the millennium. In addition, overall trends is an aspect which is examined. Despite the fact that the Holocaust has been the subject of extensive research, no study with the same selection as this one has been carried out before.

Maskuliniteter : Genusnormernas inverkan på individers sociala förutsättningar

The purpose of the thesis Masculinities ? Gender and its Impact on the Social conditions of individuals is to perform a critical study of how gendered norms influence the social conditions of individuals. This has been done by a problematization and the attempt to answer the question of how the hegemonical masculinity can be analyzed as a discourse, and how the structural aspects of this discourse inflict on the social conditions of masculinities.The question was divided into the analytical themes: the boarders of the discourse, the institutionalization of the discourse, the actuation of the discourse and the agents of the discourse. The theoretical frame is constituted by the theory of discourse by Michel Foucault, the theory of the hegemonical masculinity by R.W. Connell and a subversive identity theory by Judith Butler.

Välkommen till Kanarieöarna. Våldsam skillnadspolitik i bemötandet av turister och båtflyktingar

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.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Kommunal redovisning : Ett verktyg för kommunikation och ansvarsutkrävande

Background: Previous studies have shown that intuition occurs in decision making in small enterprises. However, these studies have not illuminated which decision attributes leads to intuitive decision making.Purpose:The purpose with this study is to contribute with an increased understanding of which decision attributes leads managers in small enterprises to use intuition in decision making and why these decisions attributes have an impact on the role of intuition. The follow-ing research question will be answered in our study: Which decision attributes leads to intui-tive decision making in small enterprises, and why?Method: To answer the research question we have conducted semi structural interviews with managers in small enterprises to achieve a deeper understanding of the role of intuition. We have also used a method called Visual Card Sorting as a complement to the semi structural interviews.Result/conclusion: The result of our study indicates that the relevance and the uncertainty of a decision have the greatest significance in the use of intuition in decision making in small enterprises.
