Askdeponi i bergrum : Metoder för slurrytillverkning

This thesis work has been carried out at the consultant company Pöyry Sweden AB in Norrköping, whom performs the task for E.ON heating Sweden AB, Händelöverket in Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops hydrogen gas in contact with water.The work has aimed to produce different suggestions of methods and equipment that can be used for the objective. Mixing method and security issues were in centre while working with the suggestions.

Leder kritisk publicitet till kritisk publicitet?

Academic research indicates that critical publicity can have a detrimental effect on brand attitudes. The negative effects have been showed to be buffered by cognitive bias elicited by strong favourable attitudes, commitment, brand certainty and brand identification. It has been proposed that the influence of such bias in a news reporting context should be studied, something that also is interesting from a brand perspective. The study therefore investigated whether a well-publicised scandal in one period can lead to increased critical publicity in the coming periods. A case study of Swedish grocery chain ICA was conducted.

Journalistik i ett nytt medium : En studie av hur journaliststudenter på två universitet i Sverige använder Twitter

The aim of this study was to find out how journalism students at two universities in Sweden, Gothenburg University and Linnaeus University in Kalmar, use the social networking service Twitter. We were primarily interested in whether the students are using Twitter as a journalistic tool, which includes gathering, production and distribution of material. The study focused on journalism students because they soon will enter the working life and therefore can provide an indication of whether Twitter is a part of the future of journalism. We have used theories of mass communication to describe the development in the area and explore how journalism has adapted to this change. The study was conducted in the form of a survey in which the students answered questions about how they use Twitter and what they think about the social networking service.

Nyateism vs teism-debatten : En analys av Dinesh D'Souza's argumentation

During the last few years the western world has seen an increasing interest in the topic of atheism, with bestselling books by writers like Richard Dawkins, Sam Harris and Christopher Hitchens. The critic of religions that these writers have brought to the table have not gone unmet, with writers like Dinesh D'Souza rushing to the defence of Chrisianity.Taking on the arguments of New York Times bestselling author Dinesh D'Souza in the current debate on the existece of God and the usefullness of religion, I here examine the claim by D'Souza that atheism, in fact, is responsible for the worst mass murders of history. In taking D'Souza's arguments and analyzing them on its own philosophical merits, with methods like the process of elimination and information evaluation (i.e source criticism), I will here show just exactly how persuasive these arguments prove to be. In the following pages we will not only discuss the role of atheism in 20th centuary totalitarianism, but also answer questions like ?Was Hitler an atheist or a theist??, ?Is atheism responsible for the worst crimes of history?? and ?Are people who believe in God in fact more moral the those who do not??.

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.

Anglosaxarna och Brittanien : Kulturell Identitet hos ett Migrerande Folk

Many questions are still left unanswered regarding the period c. 450-700 AD, when hordes of Anglo-Saxon migrants landed on the British Isles and by doing so made the starting point in the foundation of England. Who were these Germanic tribes? The theories of how the migration proceeded are today many. The two major theories today concerns whether it was a question of a mass migration or a gradual migration proceeded by smaller groups of military elite.

En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.

Bibaggar i Halländska grustäkter

This report is a result of a first survey of Halland?s gravel pits as an assignment from the County Administrative Board of Halland. The focus has been on Apalus bimaculatus, since the Swedish Environmental Protection Agency are creating a restoration program as it is red listed as Near Threatened. The purpose was also to get an overview of the pits since the County Administrative Board wants to continue this project. Apalus bimaculatus is easy to overlook since it is a short-lived beetle and it lives early in the spring.

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Lånad Identitet - En kvalitativ studie om konsumenters inställning till tillgångsbaserad klädkonsumtion

Previous studies have shown that there exists a gap between purchase intention and behavior in consumption situations. This gap is especially prevalent for sustainable or green products and even more so in terms of sustainable apparel consumption. Therefore, the adoption of sustainable fashion remains low as fast fashion dominates the industry. A counter-movement for mass consumption - access-based consumption - has reached the apparel industry and in Sweden we see it in the form of clothing libraries. This qualitative thesis uses in-depth interviews to uncover the feelings of seven consumers towards the idea of accessing rather than owning their clothing as a more sustainable consumption form, factoring in the strong identity connection that we have to our clothes and how this affects their perceptions.

Att skilja på sak och person - Hur ökad personifiering i media kan leda till bättre politisk kunskap hos mottagarna

Mass media is becoming more and more personalized and despite common ideas it could actually be a good thing. Instead of affecting the actual content of news coverage it might only have an effect on the way in which news are presented. Famous politicians more regularly become symbols and synonyms for their parties or for the government and are being used to create interest in the beginning of articles.Those are the results from a content analysis of the newspaper coverage of the Swedish parliamentary election in 1976 and 2006 in which the scientist categorized each article in one of four ideal types, counted quotes and analyzed whether personal names were interchangeable with party names without affecting the content. All three methods showing that it is the presentation, not the content, which has been personalized.At the same time, psychology-science tells us about the human brains associative learning processes, where memorizing becomes far more efficient when the information can be connected to an already known person. Increased personalization of news might therefore increase the political knowledge of the receivers..

Analys av haptoglobin i bovint serum med surface plasmon resonance biosensorteknik :

The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.

The Digital Content Era

In order to become even more competitive, a partnering with other niche players is essential in achieving a competitive advantage and it enables opportunities for reintermediation. From an intermediate perspective, there are great possibilities for those who become content coordinators to enter the market. By becoming a bundler of services and products, the content coordinators will become the actors that will capture the most profit in the value web. The value creating drivers that have been identified in the business landscape of intermediates concern owning the content or owning the customer relationship. We find the possibilities of an intermediate actor, such as a content coordinator to achieve competitive advantage through strategic fit is subject to the context and the ability of creating more innovative and co-creative distribution systems.

Varför ska vi gå till skolan? : En kvalitativ studie om skolk på gymnasiet utifrån ett sociologiskt perspektiv

The aim of this paper is exploring questions regarding the problem of absenteeism among high-school students in Sweden. Fifteen students attending an urban high-school have been interviewed about their views and experiences of absenteeism. The author analyzes the students? answers by taking into account two different sociological approaches which give two different explanations about the way young people experience and estimate education. The French sociologist Bourdieu theorized that differences in cultural capital influence the permanent internalization of patterns of thought and behavior.
