5-hydroxytryptamin (5-HT) is biochemically derived from Tryptophan. Kynurenic acid and quinolinic acid are also known metabolites of tryptophan. 5-HT is considered to play a role in depression and today selective serotonin reuptake inhibitors (SSRIs) are used for treatment of depression. 5-HT may also play a role in pain perception. The aim of this study was to investigate whether a supplement of tryptophan may affect conditions such as depression and/or pain.

The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.

Purpose: Examine if there is a connection between the athletic performance and the financial status in football clubs.Theoretical perspectives: This thesis is based on the theory that the modern football club is like every other company trying to maximize profit. The clubs should therefore use the same business strategies.Empirical foundation: The study is based on 25 observations over five years and five Allsvenska football clubs. The data is a compilation of the key ratios from the annual reports and the league table, years 2004 through 2008 in the clubs. Year 2009?s league table place is also included since tests have been done with one year?s displacement between the financial status and the league table.Conclusion:There is no correlation between solidity and the place in the league table in Allsvenska football clubs.There is no correlation between net profit and the place in the league table in Allsvenska football clubs.There is no correlation between equity and the place in the league table in Allsvenska football clubs..

The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.

Problematik: Precis som många andra turismföretag så präglas dykföretag av säsongsarbete. Under lågsäsongen arbetar året runt personalen med få turister och kollegor och under högsäsongen arbetar de intensivt tillsammans med säsongsarbetare i ett halvårs tid i en destination full av turister. När lågsäsongen närmar sig minskar turistmängden och säsongsarbetarna. Det är en livsstil för båda grupperna, men också en tillfällig period för säsongsarbetarna och en vardag för året runt personalen. Personalen har således olika förutsättningar, intressen och behov och deras arbetsmotivation skiljer sig beroende på om de är åretruntarbetare eller säsongarbetare.

Bakgrund:Handeln på aktiemarknaden har den senaste tiden genomgått en teknisk utveckling och blivit mer lättillgänglig för flera. Här verkar aktieägare med förhoppningen om att skapa en överavkastning på aktiemarknaden. I motsatt förhållande finns det studier som menar att det inte skulle finnas några möjligheter till överavkastning. Därmed blir det intressant att undersöka huruvida nyckeltal kan förklara avkastningen för dagens aktiebolag.Syfte:Syftet med studien är att undersöka hur väl nyckeltal förklarar den kortsiktiga avkastningen hos tillväxt- respektive värdebolag. Detta för att komma fram till om något nyckeltal är mer användbart för att förklara sambandet till den kortsiktiga avkastningen för tillväxt- eller värdebolag.Metod:Studien bygger på en kvantitativ metod där tre nyckeltal har analyserats med hjälp av enkel linjär regression.Resultat:Studiens resultat konstaterar att nyckeltalet, avkastning på totalt kapital, är mest användbart för att förklara sambandet till den kortsiktiga avkastningen hos tillväxt- och värdebolag.

Previous research has shown that the psychosocial work environment and leadership have a significant influence on the employees work satisfaction. Still there is much to explore regarding the employees experiences about these two subjects. A qualitative approach was used in this study to increase the understanding of the employee´s experience of psychosocial work environment and leaders role affecting it. Eight semi structured interviews were carried out at two organizations with four interviews in each place. The data was transcribed and a meaning concentration analysis was conducted.

The physical map that has been used until now can in the modern days be replaced with digital maps available in smart phones and tablets. One disadvantage of both is that the digital maps require the user to have a fully functional sight. The problem with the research done so far is that it provides little explanation as to why developers have decided to design the maps in a specific way. This thesis has been designed to address this problem.In order to provide the knowledge needed, a literature study was done to construct interview questions to an employee from SG Access AB. These answers and the literature study were used to construct interview questions to members and employees from Synskadades Riksförbund  (SRF).

Part 1 of 2  ? Lean philosophy ? five steps to get the workplace in order?Part one deals with the theory of what Lean and 5S are.Lean is a long-term approach that involves a quest to become the best on the market by increasing employee engagement, eliminate waste and focus on the right things.5S is a method of order in a system.

Lean philosophy ? five steps to get the workplace in order?Part 2 deals with the practical about 5S and a short summery about the company Wibax AB where the degree thesis took place.Wibax has a a project which involves using 5S in practice and create order in the in preparation lab and in the control room.By finding a solution to this mess reduces the time that was previously spent on searching equipment. Instead of search, the workers can do the real work..

Today environmental management systems (EMS) are common documents (more correctly, a combination of documents) that direct, steer and regulate environmental efforts within many companies. The intention of EMS is that its guidelines are reflected in how the employee carries out his everyday work tasks. This study aims to illuminate the attitudes that exist regarding the EMS at ALSTOM Power Sweden. By using questionnaires and interviews as a method to communicate with employees,a study of the existing attitudes regarding the EMS was carried out. The results were analyzed categorically and statistically and show that there are consistent attitudes among employees, but that there are also inconsistent attitudes.

Abstract We have chosen to figure out why a majority in a home-help service group in west of Sweden is, or has been sick-listed. The purpose with our work has been to investigate our area to be able to come up with different factors which can have contributed to the high numbers of this particular group. We have worked with qualitative method and conversation-interviews to be able to answer our purpose at the best way. We had separate interviews with the ten employees at their work and these interviews we chose to record with a computer. The result we got were that the group had existed for about four years and since then, they have had several different directors.

A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.

Changes are occurring in most organizations today and due to the fact that changes often are harder to implement than they seem, it often takes much longer time to implement them than the management have planned. During an organizational change theorist claim that communication between managers and employees is one of the most important things to consider. Therefore, in this essay, our aim is to closer investigate which needs of information and communication co-workers have during a planned organizational change. To collect data, we interviewed five co-workers and one manager who works in an organization which has gone through a major change. Our theoretical framework comprises former research of organizational communication, employee?s needs of communication, change communication and theories of uncertainty during organizational change.

Eftersom intressenter visat sig använda revisionsberättelsen som beslutsunderlag, kan en reaktion på den orena revisionsberättelsen innebära en negativ följd för företaget. Därmed har vi undersökt hur det reviderade företagets organisatoriska outcomespåverkas av den orena revisionsberättelsen. Vidare syftar även studien till att förklara hur vidtagna åtgärder begränsar effekten av den orena revisionsberättelsen. Med utgångspunkt från tidigare forskning och teori skapadesegna hypoteser. Hypoteserna menar att den orena revisionsberättelsen påverkar organisatoriska outcomes och att dessa effekter kan dämpas genom vidtagna åtgärder.För att realisera syftet genomfördes en dokumentstudie.
