The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Läroplanen är föränderlig över tid och har kunnat återspegla sin samtid samhällets rådande grundintentioner. Piaget, Dewey och Vygotskij har alla påverkat den svenska läroplanens utformning på olika sätt och skapat olika förutsättningar och svårigheter för individen och dennes utveckling. En undersökning som byggde på 15 lärares upplevelser fokuserade på huruvida den senaste läroplanen skapade problem för eleverna och hur de i så fall uttrycktes. Resultaten visade att läroplanen i sig inte var den avgörande, utan att yttre faktorer såsom media, samhällets struktur och föräldrar hade en större betydelse för hur eleverna fungerade i skolan. Flera lärare kommenterade nya fenomen som råare attityder mellan flickor, lustbarn och starkt präglad individualism vilka alla kan ses som vidare underlag för framtida forskning..

Parallel import in the European Union is the perfectly legal activity under Art. 28-30 EC of buying goods in a low-price country in order to ship and sell them in a high-price country. The pharmaceutical market in Europe is subject to the subsidiartiy principle of Art. 5 EC and heavily characterised by national regulations that lead to significant price differentials between – generally speaking – Northern and Southern Europe. This incites the activity of parallel traders in the first place, who act as arbitrageurs.

The Swedish automotive industry has since way back been struggling with bankruptcy, abroad buy outs and staff cuts. Competition and pressure on prices are two factors that affect the automotive industry. Because of this, the companies are pressured to continuously developing their work in addition to be able to compete on the market. The aircraft industry has successfully managed to implement additive manufacturing (AM) and for motorsport has several components manufactured with AM been used. When AM is used as a manufacturing method, there are a number of advantagesthat follows.

Our purpose with this essay was to analyse the play "Night Is the Mother of Day" written by Lars Norén, and to investigate how the family members/characters in the play interacted.By analysing the family with help from the system theory and by comparing the family with scientifically proven facts regarding drug abuse complexities, this essay explains the family's behaviour pattern and main dysfunctional problems.This essay explains the similarities and non similarities between the science and the specific theatrical play being used. It also rise the question whether there are advantages with analysing plays in terms of increasing the ability to relate to difficult problems and create a greater empathy and understanding for people involved with social problems..

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

The value investing philosophy, which can be traced at least to the teaching of Graham and Dodd in the 1930?s, entails identifying and investing in potentially under valued stocks with a potential for extraordinary returns. The focus of this thesis is to identify patterns and characteristics in financial accounting data preceding creation of shareholder value. The authors of this thesis utilize a multivariate discriminant analysis in order to identify indicators of value creation and subsequent extraordinary returns in value stocks. A discriminant function is derived which successfully identifies which value stocks will eventually become growth stocks.

SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.

Forskning har visat att människor hjälper varandra av såväl egoistiska som altruistiska skäl. Hur ter det sig hos volontärer? Ställer volontärer upp för de hjälpbehövandes eller för sin egen skull? Den här uppsatsen syftar till att undersöka volontärers motiv till att hjälpa. Skiljer motiven sig åt beroende på om engagemanget sker i Sverige, inom Europa eller i en annan världsdel? 40 volontärer berättade skriftligt om sina volontärupplevelser.

Faith is a phenomenon that engages the individual into emotional, social and daily manners.Religion tends to engage the individual in different levels in the daily life. In the church communion, there is a belief to the traditional and the repeteated behaviour. This shared group is strength by ceremonies and rituals and people in this collective somehow experience another type of reality. This study has a social - psychological perspective and the purpose is to study people?s know-how of faith and why they seek religion in today´s secularized society.

Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

It is well proven that physical exercise has an impact on our bodies as well as our minds. The aim of this study is to examine if this impact also affects economic behaviour. Three hypotheses regarding the impact of acute exercise on overconfidence, risk enhancement and well-being have been tested by collecting questionnaires from 364 participants at Friskis & Svettis, Kungsholmen who all were asked to answer the questions either before or after exercising. The differences between the before and after group were analysed, indicating small increases in all three test areas after exercising. These increases were, however, not large enough to reject any of the null-hypotheses of zero effect on the given five per cent significance level.

The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company. I have chosen a company placed in south of Sweden. The productions are crop farming and pork.
