AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.

The present study investigated free narratives in 72 children between 3;11 and 9;0 years. Participants were recruited from a multilingual environment in eastern Gothenburg. The children were instructed to make up their own stories after being provided with openings, ?Story stems?. The stories were then transcribed and analyzed on micro- and macro level and narrative evaluation.

Some children develop externalizing and internalizing behavior problems at an early age. Previous research has often treated these children as a homogeneous group, the purpose of this study is to show that this group of children is in fact heterogeneous. Data from theSOFIAstudy was used and preschool pedagogues were informants. The sample contained 2121 boys and girls between 3-5 years. Groups of children with the behavior problems and the risk factors AD/HD symptoms, fearlessness and callous-unemotional traits were created.

Wind and wind damage has become a hot subject because of the storm ?Gudrun? in January 2005. The main purpose of this study was to establish how the land owners attitude toward preventive wind damage actions was changing immediately after they had been struck by a storm. The result of the study was built on interviews. In springtime 2005 a total number of 20 private land owners were interviewed. Ten of the landowners lived in the province of Småland and ten in the province of Värmland.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

The purpose of this essay is to investigate modern influence in the painting Strömkarlen, by Ernst Josephson. Strömkarlen was painted 1884 in Norway. First the essay performed an investigation of earlier researchers statements to establish a ?common truth? that puts the painting in a realistic/naturalistic-romantic context. With the help of Yve-Alain Bois? model, where he sees art from the painters point of wiew, it was possible to use two articles, written by Ernst Josephson in the fall of 1884, where he debates the conditions for art and artists in Sweden.

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

The EU guarantees the free movement of persons. The citizens of the EU Member States have the right to move freely without barriers within the EU borders and this result in an integration of the peoples in Europe. The integration result in several international family relationships. It is not unusual in the present situation that families have international relations. For example, spouses in a married couple may have different nationality.

AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.

The purpose of this study is to find out how some Swedish preschool teacher discussing how children's Swedish colloquial interaction can be enhanced in the free play. In this case where children are aged three to five.My research questions in the study are:-          What type of free play do preschool teachers talk about in relation to children's Swedish colloquial development?-          What do preschool teachers say about child's colloquial interaction?-           How do preschool teachers reason regarding in what environment children?s colloquial interaction occurs?In my study I have used an interview with elements of a visual method called The Diamond. The approach is that the participants in the interview will be enhanced to discussing about a wise certain number of images. These images are then to be ranked accordingly with a specific theme and terms.If a child has difficult to speak, you can take help of  the interest the child has, the child can tell you and the other children what he or she know about the interest.

This master thesis encompasses an inventory and risk classification of four disused landfills within the municipality of Uppsala, Sweden. The model of the classification; ?Method of Surveying Contaminated Sites? is developed by the Environmental Protection Agency and can be used as a framework to investigate and describe the environmental damage and the level of risk for each object. The risk classification model has a rating from 1 to 4, where 1 represents a very high risk while 4 is a small risk. Risk class depends largely on the type of land use that exists on the object, and hence, various benchmarks must be taken into account.

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.

Med denna uppsats vill vi ge läsaren en uppfattning om vad Free Software och OpenSource (FOSS) handlar om och mer specifikt analyseras huruvida FOSS kan fungera ien kapitalistisk värld eller inte. Den grundläggande idén med Free Software ochOpen Source, eller fri programvara och öppen källkod, är att ge varje användare avett datorprogram rätten att fritt köra, undersöka, ändra och vidaredistribueraprogrammet.Författarna ställer i uppsatsen frågan ?Hur kan pengar tjänas på FOSS?. Uppsatsensyftar till att försöka bena ut denna frågeställning. Frågeställningen ger upphov till tvåperspektiv; dels i meningen ?på vilka sätt kan man tjäna pengar på FOSS? och dels ibetydelsen ?hur kommer det sig att det går att tjäna pengar på FOSS då det är gratis?.Uppsatsen knyter an till litteratur kring FOSS samt ekonomisk teori och är främstteoretisk till sin natur.I uppsatsen visas att gamla beprövade affärsmodeller inte kan användas rakt av förföretag som använder eller utvecklar produkter baserade på Open Source.

The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
