Population and management models for the Swedish wild boar (Sus scrofa)
The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.
En studie av retentionen i floden Oder och dess avrinningsområden, Polen.
Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.
Fanan, förrädarna och friheten : Musiktexter med ideologiska teman från Tredje Riket till Vit Makt-rörelsen ? en komparativ textanalys
The making of a cultural historical exhibition usually involves the collaboration of two categories of professionals: the curator, in charge of the exhibition content, and the designer. From these positions, representing content and form, the team is in charge of cooperating towards a shared goal ? the exhibition ? which is the spatial expression of ideas.This MA thesis is based on my work experience as a designer of cultural historical exhibitions. By means of situations where my perspective collided with that of the museum curators?, I examine our different concepts on a number of issues: the meaning of an exhibition; the process; and the perception of what our respective roles are.
Prehospital omvårdnad av patienter med akuthjärtinfarkt som transporteras direkt till PCI : ? intervjustudie med sjuksköterskor i ambulans
The prehospital management of patients with acute myocardial infarction (AMI)now includes 12-lead electrocardiogram transmission directly from the ambulance to hospital.If the ECG shows ST-elevated myocardial infarction the patient should be transported directlyto a hospital with capability for percutaneous coronary intervention (PCI). Aim: The aim of this study was to describe how ambulance nurses experienced the prehospital management of patients with AMI who are transported by ambulance directly to hospital for PCI. Method: Semi structured interviews were conducted with eight ambulance nurses. Data were analysed using qualitative content analysis. The categories that emerged were: Use ofcompetence, Responsibility and Insufficiency. Result: The result showed that the ambulance nurses felt secure when they cared for patients transported directly to PCI. The nurses assessed the patient and decided how he or she should be cared for.
Livscykelkostnadsanalys för beläggningar i containerterminaler : en förstudie för bättre beslutsunderlag vid investeringar i terminalytor
Pontarius AB har tillsammans med Göteborgs Hamn AB identifierat behovet av en utvecklad holistisk modell för bedömning av investeringar i terminalytor. För detta har en första ansats gjorts med den interna livscykelkostnadsanalysmodellen Total Cost of Ownership and Operations (TCOO). Livscykelkostnadsanalys (LCCA) är ett verktyg för att handskas med ett projekts totala kostnader vid investeringsbeslut och bedömning av alternativ. Generella livscykelkostnads-modeller är svåra att ta fram, varför istället utförliga modeller vanligen skapas för specifika områden. För vägbeläggningar, och tillviss del flygplatsbeläggningar, finns utförliga sådana metoder, men för beläggningar i containerterminaler saknas det.För att fortsätta utveckling mot en bättre bedömningsmodell för terminalytor syftade studien till att identifiera kostnadsparametrar som sett ur ett livscykelperspektiv påverkar kostnaderna för containerhamnterminalytor.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in
landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is
collected and checked.
Solidaritet möter säkerhet - Vad 'immigranterna' får representera i immigrationspolitisk diskurs
This essay concerns the notion of how immigration politics, defined as a political discursive structure that explains and justifies how and why the movement of people into a state's territory is restricted and controlled, has come to present its purpose not as solidarity with the 'immigrants' wanting to enter the state but as a protective measure for the state's citizens. By using discourse theory combined with theories from the International Relations field I attempt to explain why and how such a discourse positions 'immigrants' as a threat to the state.First, I concentrate on why an immigration politics discourse would position 'immigrants' as a threat. I argue that in order for people to construct their identity, the 'outside' what they "are not" has to be repressed. In the same way, the state has to dislocate the "outside" and create threats to uphold its supremacy. These boundaries are set to create a feeling of predictability and security, and ultimately they are a way of making peoples' "world" coherent.
Språk, utveckling och lärande : En diskursanalys av språkbegreppet i förskolans läroplan
The study´s purpose is to investigate the underlying norms of how the concepts of language development and learning, used in the preschool curriculum. Knowledge of the concepts underlying norms can help to make visible what approach preschool teacher is expected to have to children's language, in relation to development and learning. The results of the study may in turn provide a picture of societal norms on children in preschool and a deeper understanding of the importance of preschool to review and analyze the content of the curriculum, then it is not a foregone conclusion.Theoretical basis is curriculum theory, which involves studying curricula in order to create a knowledge of a society and its cultural, social and economic demands. Norman Faircloughs critical discourse analysis is used as a method, in order to achieve the study´s intention and answer the questions at issues in the study. The critical discourse analysis considers that the discourse is creating the social world through language.The results of the study show that there is a language in the curriculum as normatively may influence preschool teacher.
Hur växer den sibiriska lärken i Sverige? : tillväxt och höjdutveckling i Siljansfors försökspark
Sibirisk lärk (Larix sibirica och Larix sukaczewii) är ett snabbväxande barrträd som odlats i Sverige i mer än 100 år. Trots det finns det få studier angående dess potential i Sverige och dessutom visar studierna på skilda resultat.
Med data från bestånden med sibirisk lärk i Siljansfors försökspark, har höjdutveckling och tillväxt studerats. Med detta kandidatarbete avsågs att fastställa sambandet mellan medelhöjd och beståndets totala volym, ta reda på om den sibiriska lärken slutar växa på höjden vid 80 års ålder samt ta reda på när den årliga löpande tillväxten sjunker under den årliga medeltillväxten.
Totalt ingick elva avdelningar med sibirisk lärk, som var mellan 48-94 år, i studien. Genom regressionsanalyser har samband mellan aktuella variabler skapats och analyserats. Resultatet gav att sambandet mellan medelhöjd (m) och total beståndsvolym (m3sk/ha) följer regressionsekvationen:
Total beståndsvolym = - 73,3 + 13,1 medelhöjd + 0,386 medelhöjd2
Resultaten var att lärken inte slutar att växa på höjden vid 80 års ålder, snarare tycks höjdtillväxten inte avstanna förrän efter 90 år.
Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :
Abstract
The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment.
In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: The effect of naturally existent beta-glucan in adults with hypercholesterolemia. - a systematic review with focus on the Swedish food market.Author: Ida Edman Hellberg, Frida HanssonSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 01, 2014Background EFSA states in 2010 that there are good evidence that three grams of beta-glucan/day from oat as a part of a balanced diet, has a positive effect on total cholesterol and LDL.Objective Evaluate if there is evidence for primary treatment of lifestyle related hypercholesterolemia with products naturally containing beta-glucan.Search strategyIn February 2014 the databases PubMed and Scopus were used for article research. The search terms used were; cholesterol level, beta-glucan, hypercholesterolemia, oat and barley.Selection criteria Articles, written in Swedish and English, on RCT-studies conducted on otherwise healthy adults with hypercholesterolemia (serum cholesterol >5,0 mmol/L) were included. The intervention product must naturally contain beta-glucan, and an equally product should be retailed in Swedish grocery stores. The control group needed to be supplied with a placebo product and the participants could not be on any lipid-lowering medication.
Buddhismen i greppet av nationalism, islamofobi och våld : En analys av den burmesiska theravadamunken Ashin Wirathus uttalanden
In the years between 2012 and 2014, Burma has been shaken by waves of violence against Muslims which has resulted in destroyed mosques and shops, at least 140 000 displaced and 200 killed persons. The person who is said to lay behind this violence is the Burmese Theravada monk Ashin Wirathu. Being the founder and leader of the radical Buddhist movement 969, he has been accused of indirectly motivating violence against Muslims and has been portrayed with titles such as ?The face of buddhist terror?. This essay investigates the relation between Wirathu and the anti-Muslim violence by applying the method of content analysis on a speech of him.
Protein i korn : En torkstudie utförd med etablerade analysmetoder på tre kornsorter
A study was performed to evaluate whether established methods of analysis of protein content in barley (Kjeldahl, Dumas, or NIT (short for Near Infrared Transmittance)) gives different results for wet and dried barley. This was carried out because there are concerns regarding the well-worn NIT prediction model giving different results for these conditions and that such an error causes significant price fluctuations on the market. By performing analyses of samples, both before and after drying, of the three different barley varieties Tipple, Prestige, and Quench, with all the techniques, data was obtained that could be analyzed statistically. The study showed that the NIT prediction model gives results for wet barley that is about 0.29 percentage points higher compared to dried barley. This difference was also statistically significant when a t-test was performed.
Besökattraktionsutveckling i Fisksätra : En studie av intresset för ett nytt kulturhistoriskt besöksmål
Fisksätra has a historical background that goes back to the battle between Russia and Sweden that took place in 1719. This battle is known as "Slaget vid Stäket". Today there are plans to develop Fisksätra as a tourist destination where focus lays on the historic factor of the battlefield that took place there. As of this a project called the HAMN project has started to try to develop a new experience park at this destination unlike any other.The aim of this essay has been to study how much potential this experience park has to become a popular tourist destination in the future, while looking at the potential interest of the foreign tourists. This essay is written as an assignment for Göran Andersson, who is in charge of the tourism department at Södertörns Högskola.
Förekomst av reaktiva syreföreningar itransportsperma från hingst
Rental rates and land prices have gone through substantial changes the last two decades. The prices have both gone up and down since 1990 but from 1995 to 2008 land prices increased with 272 percent and rental rates with 61 percent. What factors that have the largest impact on rental rates and land prices are hard to determine but factors that may affect the price are the desire to live in the countryside and the expected profitability in agriculture. Prices of products and inputs are factors that affect the profitability in agriculture, but the profitability is also affected by agricultural policies. The economic for Swedish agriculture have changed several times over the last 20 years as a result of changing agricultural policies.The agricultural policies largely affect farmers behavior and decisions.
