Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

Sjuksköterskors upplevelser när de medverkar vid genomförandet av abort : En litteraturöversikt

Background: Abortion implies that the pregnancy is interrupted. According to the World Health Organization approximately 46 million induced abortions are carried out each year. Different methods of abortion can be used such as medical and surgical methods. The medical method especially affects a nurse?s experience of the procedure.

Varumärkesetablering : med en trend som hävstång

The aim of our thesis is to study and analyze the components and features a brand should have to provide a solid foundation for brand building. Furthermore, we show how brands can make use of trends in a brand establishment.This paper is written from a qualitative approach. Through both structured and semi structured interviews, we obtained valuable information from our respondents. Our frame of reference and empirical foundation are linked together through an abductive approach which has resulted in our analysis and conclusions.A trend brings with a set of emotional characteristics, which companies can?t influence but must adapt to.

Årstidsdynamik för kvicksilver i ett sövattensediment :

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Kommunal IT-samverkan. En studie om barriärer vid implementering av IT-tjänster inom kommunal verksamhet

Economic changes, globalization and an aging population are phenomena that haveaffected the municipal development in the late 1900s. To address these challenges,cooperation in specific areas between municipalities in the 1990- and 2000's hasincreased. This is referred to in the literature as municipal cooperation. IT is one ofthese areas of collaboration and is seen as a potential solution to streamline municipaloperations. IT implementations are often complex projects involving a large number ofpeople.

Från läsesällskap till stadsbibliotek: Skövdes bibliotekshistoria 1830-1940

The purpose of this Master?s thesis is to describe the development of the most important libraries in Skövde, starting from 1830. We conclude our examination about 1940, when the municipal library has been active for almost ten years, and the libraries started by the temperance and working-class movements have been deposited at the municipal library. In order to explain this process we describe the development of the Swedish public library and its predecessors, such as reading societies and the popular national movements? libraries, as a background and comparison to the early libraries in Skövde.

Jag har ropat så högt jag förmått, jag har upphävt såväl stridsrop som bönerop

Lucie Lagerbielke (1865-1931) is a fairly unknown writer who lived and worked in Stockholm. All her life she was writing with a strong aim to tell her truth and she had an aspiration to change the world for the better.  Her main points of views in her authorship were; oneness, the power of love, a belief in a supreme purpose to be served, religious mysticism and the interest in understanding and to prove the transcendent on a scientific basis. In my discussion I relate to Rita Felski and her expression the popular sublime, a term she applies to illustrate a sublime way of writing that was common in women popular fiction in the late nineteenth-century. This romantic literature with escapist tendencies was popular among the ordinary readers but very seldom met with success with the professional critics.Focus in this BA thesis is the spiritual Lagerbielke and in what way she wants to change the society. I have analyzed two of her novels, Daniel- ett lifsöde and En sällsam upplefvelse with intention to examine how she used her novels to plead for her cause.By making such an analysis I come to the conclusion that both her novels have the purpose to emphasize her philosophy of life.

Utvärdering av energiberäkningsprogram : Att användas i tidigt planeringsstadium för byggnader

The regulations for energy consumption are consistently getting more and morestrict. This leads to a higher customer demand for energy analysis early in the buildingdesign process. Many building planners and architects use powerful modeling softwareto visualize their projects. These digital models contain sufficient information aboutthe building?s physical characteristics for reliable energy analysis.

Aktörer och strukturer: en studie av Karlstads stadsbiblioteks framväxt

The aim of this thesis is to examine the underlying causes for the opening of Karlstad Public Library. In doing so a theory based on the actor/structure model within social theory is used. The structures and actors are intertwined and therefore need to be analysed together. To do so the theory poses a series of questions that needs to be answered. The method used is document analysis.

Värmebehandling av segjärn med hög kiselhalt

Bakgrunden till detta examensarbete var att Qumex Materialteknik vid ett flertal tillfällen konstaterat att material av typen SS 0725 har uppvisat bristfälliga härdresultat. Materialet, som är relativt nytt på marknaden, är ett gjutjärn av typen segjärn och utmärker sig gentemot andra segjärn på grund av sitt höga innehåll av kisel. Då segjärn enligt den nu gällande EN-standarden klassificeras efter sina mekaniska egenskaper uppstår ett problem gällande SS 0725. Materialet uppfyller de krav som är ställda för EN-GJS-500-7 och hamnar därmed under samma materialbeteckning som ett segjärn med betydligt lägre kiselhalt. Att två material med olika kemisk sammansättning hamnar under samma beteckning kan innebära problem.

Moräntäckta rullstensåsar i Västerbottens inland

The purpose of this study was to map the distribution of till-covered eskers in the inland of Västerbotten County in northern Sweden. The top layers of big eskers along the valleys of Öre River, Ume River and Vindel River were investigated through shallow digging. Findings were investigated through field assessment and soil analysis and many locations with till-covered eskers have been identified in Västerbotten's inland in this survey. The till covering the eskers has probably been transported only short distances and has its origins in glacifluvial material. The pattern is not consistent and there are areas where till does not cover the eskers.

Svenskars färd mot Mörkrets hjärta : Om svenska militärer som sökte tjänst i Kongostatens kolonialarmé 1895-1906

The aim of this paper is to map and analyze what role Swede's played in King Leopold II's colony in the former Congo Free State. Letters and messages that arrived at the Congo Consulate in Sweden between 1895 and 1906 have been used as the paper's primary sources. Application letters from 32 different Swedes, seeking to join the Congo Free State Army, to the General Consul of the Congo Consulate, Hans Hugold von Schwerin, have been used as primary sources, and constitute the basis of the paper's analysis. The letters arrived at the Congo Consulate in Sweden between 1895 and 1906. The applicants were all men of different social classes, and were between the ages of 20 and 30 years old. Their chief reasons for applying were primarily for own financial gain or because they did not get a chance to serve in the Swedish army.

Hav och Strand : stenteknologi och marin anpassning på Gotland under Senboreal/Tidigatlantisk tid

The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..

Hur doftar parfymreklamen? : En Studie i hur man kommunicerar doft genom bild i parfymreklamen

With the help of image analysis and scent theory, we have made an analysis that explains how the perfume smells in advertising. There are many different factors that play a role in our perception of smell by image. We have found that using the connotations we can get a sense of the scent. What helps us along the way, the colors, the women and the environment. From this one different conclusions are mad and we create a scent sensation..

Andraspråksutveckling i den mångkulturella förskolan

This thesis deals with two types of agrarian remains in relation to settlement remains; clearance cairns, low stone walls and house terraces in the area of Northeastern Uppland and the area north of Lake Mälaren, during the middle Iron Age. The aim whit this thesis is trying to get a better understanding of the relation between agrarian and settlement remains in Uppland. Three places have been chosen where these three elements are present and they are interpreted through Richard Whites concept of middle ground but also Landesque capital. The three elements have shown to be expressed in different ways in all three sites. It is possible to see two areas with different traditions, but also to see two areas that closely interact with each other, this opens up for a new discussion around agrarian remains in both areas.
