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.

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.

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.

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.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Adherence to medical ordination is low and for long-time medication it is estimated to be as low as 50 percent. Depending on the prescribed drug this could lead to adverse effects and/or loss of effect of the drug. Information about why a drug is prescribed is important patient information and is thought to help increase compliance with the physician?s prescription. According to results from a recent study of visits to the emergency room at Karolinska Universitetssjukhuset in Solna, Stockholm, medically related problems were the cause in about 30 percent of the cases.

Today?s forest managers implement a large number of methods to increase the amount of dead wood in Swedish forests. They use everything from high cutting of trees to girdling trees and burning forests. However, implementation of these measures without proper knowledge of their consequences is a common problem. This study has been performed to increase knowledge about two of these measures, girdling and high cutting, and how these actions affect the number of wood-living insects living on dead trees.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.

This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.
