St. John?s wort extract is composed of a large number of components, about 150, but the most studied and interesting substance are hyperforin and hypericin. The herb is very popular and it is known for its pharmacological efficacy in numerous disorders. It is used for treatment of mild to moderated depression as an alternative to synthetic antidepressants.

This essay deals with the rationale and aims for doing cultural or aesthetic activities and projects in schools, and gives special focus to a specific group of students, attending schools provided at special residential homes for young people (sa?rskilda ungdomshem). These homes receive young people with psychosocial and substance misuse problems and who show tendencies towards criminal behavior. The essay investigates how working with a cultural project in schools at these residential homes is justified and also elucidates how this specific group of students and their problems are constructed in the documents surrounding the project. The essay will further ponder over possible educational and pedagogical consequences of these constructions.The investigation has its theoretical frame work in curriculum theory.

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Adjustment to acquired hearing loss can be understood as a process of learning and change where the point of departure is the subjective apppraisal of a person?s hearing loss in a social and cultural context. The aim of the study was to describe women?s thoughts, emotions and actions prior to audiological rehabilitation, since these are considered important for the ongoing process of adjustment and for the planning of rehabilitation. A phenomenographical approach was used in order to describe the variation in the women?s attitudes before attending rehabilitation.

ABSTRACTBackground: Children and adolescents growing up in families where parents have serious problems are exposed to an increased risk of developing poor mental or physical health themselves. In a support group work they can meet other children in the same situation, receive help and support to process their emotions and manage their everyday life.Aim: To investigate if support group work at Trappan can reduce the psychological problems load and increase the experience of life quality, hopefulness and optimism in children and adolescents growing up in families where either addiction or mental illness occur in one of the parents. The purpose was also to investigate if there was any difference between these both child groups regarding psychological problems load, experience of life quality, hopefulness and optimism before and after support group participation.Method: Questionnaire study on children and adolescents of parents with addiction or mental illness. The children participated in support group work at Trappan. The measuring?s were conducted before and after support group participation.Results: In both groups an increased life quality in connection to finished support group participation was observed.

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Background: Enterprises often refer to their employees as ?Our most valuable assets? in annual reports and other written statements. In reality, employees are seen as an expense rather than an asset in annual reports and the voluntary disclosure is often insufficient. Human capital disclosure has been discussed through decades and the latest topic in voluntary disclosure is called integrated reporting. Knowledge firms should disclose more about their employees than industrial companies due to the fact that the employees are a considerably more important asset to these types of enterprises.Purpose: The purpose of this thesis is to study the disclosure of human capital, compare the disclosures between knowledge firms and industrial companies, and study the development of the human capital disclosures between the years 2003-2013.

What are the basic thoughts formulated in the Heraclitean fragments? A cosmology, a philosophy of nature, the idea that all can be reduced to a single substance? There is always a risk that Heraclitus is fitted into a thought pattern he doesn?t belong to, if we ? from our present horizon ? focus on continuity in an attempt to frame his thinking as part of an overall progress, running from the so-called pre-Socratics to Aristotle, in the history of philosophy. If we picture the dawn of Western civilization as an early development of scientific thinking, built on a gradual and continuous growth of knowledge, we will easily go astray as we try to discover the Greek origins of philosophy. Assuming, for example, that the readings of Heraclitus as a natural philosopher have come to a dead end, can we approach the fragments from a different angle?The aim of this paper is not to give a systematized reading of all the remaining fragments of Heraclitus, but neither to necessarily contradict the various interpretations that emphasise how these shattered remains reflect a coherent philosophy.

Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health problems in the surrounding. The dry matter losses and reduction of fuel quality can have economical effects. The aim of this thesis project is to develop guidelines on how to store large amount of biomass at Vattenfalls heat and power plants in an optimal way.

Most of the saw and pulp industries have stored wood nearby their production, the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality. One drawback of wet storage of wood is the leaching of chemical substances into the surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and organic substances. These substances can cause problems for the surrounding environment. The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.

The globalization has increased the trade between different places and countries. Products are now available from all over the world, but this requires transports that have consequences in the environment as well as the economy. New professions are creates that do formality, organize, administrate and implement other businesses transports. Their operations are between the business and customer and they are called logistics companies. The purpose of this report was to study third-party logistics and why more and more companies use this logistics services.
