Mineralämnen i fullfoder : studier på 20 mjölkkogårdar i Halland
In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.
Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård
Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..
Disputing the Economic Man - a quantitative study on whether investor decision-making can be distorted by altering the presentation of an Exchange Traded Fund
During recent years, financial innovation has given rise to numerous structured investment opportunities aimed towards the general public. These have enabled private investors to engage in high-risk investments offering as much as 400 per cent leverage while oftentimes not fully having grasped the risk involved. The issuers of these securities have been criticized for using advertising of a too aggressive and misleading nature.By presenting 819 potential investors with two different investment opportunities yielding the same return over a six day period, we have aimed to assess whether the inclination of being affected by judegmental heuristics varies with factors such as knowledge, overall attitude towards the asset class, risk appetite and experience from previous investments.We have observed that investors' perception of the attractiveness of an investment can be distorted by altering the information presented to the investor. However, our findings show that this tendency decreases with an increased level of knowledge, experience and risk appetite..
Barn med autismspektrumtillstånd i förskola och skola : Fyra pedagogers erfarenheter och syn på en skola för alla
The purpose of this study is to describe and analyze four educators? views and experiences of working with children with Autism Spectrum Disorders in relation to the concept of "One school for all". Research has shown that a segregating perspective is dominant in the school system, but the education act says that all children have a right to an equal education.My starting point for this study has been the concept of term "One school for all" and the problems that can occur in working with children with Autism Spectrum Disorders. A school for all is a school where all children are welcome and where all children sees as equals regardless of what background or disability they have. This study will be important for newly graduated teachers who are not aware of Autism Spectrum disorders.

Skogsbristen i Smålands bruksskogar : en studie av träkolsförbrukning vid Storebro Bruk 1793-1850
The forest in the county of Småland has been utilised for a long time. One of the most
important forms of utilisation of wood has been charcoaling for the benefit of the iron
industry. Shortage of forest in relation to the iron industry, was discussed already in the 17th century in Sweden. The aim of this study was to analyse the purchase and consumption of charcoal at Storebro Bruk, an ironwork in Småland, during the period 1793-1850, as well as analyse the shortage of forest at the time. To determine the utilisation of the forest in the area, I have used historical sources from Storebro Bruksarkiv.
Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :
The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population.

Om associationer till vatten
This paper is intended to provide a picture of which associations water can wake in the human
mind from the perspectives of garden history as well as from that of environmental
psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a
basis for discussion and as a starting point for different forms of design work in landscape
architecture. The historical perspective emphasizes the importance of water as a condition for
the emergence of gardens and in a wider perspective the importance of water in early cultures.
Also, I describe a picture of how water has been used throughout the history of gardens from
early Egypt to the baroque era. The garden history analyzed from an art historical perspective
gives a picture of human associations to water, and the history behind these associations is
presented. As a compliment to the art history approach, I have chosen to highlight our
associations with water from the perspectives of environmental psychology and evolutionary
science.
Hyresbostadsfonder - ett placeringsalternativ för välbärgade?
Hyresbostadsfonder är en ny placeringsform i Sverige som erbjuder privatpersoner, företag och institutioner att äga hyresfastigheter och erhålla avkastning från förvaltningsöverskott och värdeökning. I denna studie jämförs aktie- och obligationsfonder med en simulerad hyresbostadsfond ur ett risk kontra avkastningsperspektiv. Fonden baseras på data över den svenska fastighetsmarknaden från Svenskt Fastighetsindex och Investment Property Database, därför att placeringsformen är ny och det råder brist på historisk data från verkliga aktörer.Målet med studien är att besvara om hyresbostadsfonder är ett konkurrenskraftigt alternativ till aktie- och obligationsfonder. Utöver finansiella jämförelser redogör författarna eventuella dolda risker och nackdelar med placeringsformen.Resultatet från studien visar att hyresbostadsfonden har presterat bättre än både aktie- och obligationsfonderna under perioden 1988-2008. Bidragande faktorer till denna utveckling har identifierats och redovisats.
Hur har EU:S regionalpolitik påverkat Sveriges regionalpolitik?

The study builds on the theoretical framework that is Europeanization, the top-down approach, which stipulates where you can find evidence of this influence. To obtain the information that I needed to answer my question formulations, which main question formulation are; in which way has the EU regional policy influenced the Swedish regional policy? I used the method of literature analysis. Both the theoretical framework alongside the chosen method pointed me to analyze the public debate in Sweden in the regional question.
AP-fondernas utveckling : en jämförande studie om avkastning och risk mellan åren 2002-2010
Bakgrund: Det rådande pensionssystemet i Sverige består av sex så kallade AP-fonder. Genom åren har pensionssystemet flertalet gånger kritiserats för dess låga avkastning.Problem: Vår huvudfråga är att jämföra AP-fondernas risk och avkastning med aktiemarknaden som helhet, detta ska ske med hjälp av två jämförelseindex: MSCI World och SIXRX.Syfte: Syftet med uppsatsen är att jämföra de fyra första AP-fondernas risk och avkastning med aktiemarknaden som helhet under åren 2002-2010.Metod: Vi har använt oss av en kvantitativ metod, genom att samla in information från AP-fondernas årsredovisningar och hemsidor. Vi har samlat in historisk data, som vi sedan har bearbetat och analyserat.Slutsats: De studerade AP-fonderna har presterat sämre än aktiemarknaden..
Test av litiumheparinplasma fo?r analys av folat med Siemens Advia Centaur® XP samt effekt av inomhusbelysning o?ver tid
Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).
