The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

Den här uppsatsen har till syfte att undersöka om fusioner och fusionsvågor i Sverige mellan 1986 och 2013 kan förklaras av felvärderingsteorin. Enligt teorin uppstår fusioner mellan en köpare som är relativt övervärderad jämfört med målbolaget på en övervärderad marknad. Fusionsvågor uppstår då fusionsaktiviteten under en period är ovanligt hög. Vi undersöker felvärderingen med hjälp av en uppdelad ?Market-to-Book? där två komponenter ingår: en kortsiktig och en långsiktig felvärdering.

This essay focuses on how women and the woman emancipation are described in high school history textbooks from the years 1970, 1980, 1990 and 2000, using the theories history consciousness and gender. Two textbooks are analyzed from each period. There are several gender theories, in this essay it is Yvonne Hirdman?s theory concerning woman- and gender history that is used. This means that the woman emancipation and women?s history are analyzed from the perspectives invisible, add, and-, how- and gender history.

The purpose of this paper is to compare two different portfolio strategies consisting of insider transactions and stock recommendations and examine whether they posses any information advantage.  The portfolios are balanced once every three-, six- and twelve- months in the period of 2007-2009. Our results show a pattern for these investment strategies. The portfolio consisting of insider transactions generates a positive return in equity in a negative market environment and the opposite reaction in a positive environment. The result for the portfolio consisting of stock recommendations show a positive return of equity in positive environment and the opposite effect in negative environment. The pattern that has been observed can be classified as an anomaly.

During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.

After the last election Sweden has got a government that claims to be feminist. This thesis discusses whether the change of labels has also brought along policy formulated in a feminist way, arguing that the way policy is expressed affects how people see a certain problem. Three policy proposals are analysed, and in only one case the government seems to have been influenced by feminist ideas. The other proposals partly support claims made by new institutionalism that norms and routines in an organisation work to resist policy change, but also shows that feminist ideas are resisted more actively. The fact that so called policy entrepreneurs was present in the policy process at a certain period in time, probably counts for one explanation to the exceptional policy.

This study sets out to investigate how the roll of the teacher is constructed in the Swedish Teachers? Unions trade publication. Based on the theory of social constructionism we have used the method of critical discourse analysis to establish dominant trends and patterns in how the roll of teacher is constructed in editorials in Swedish Lärarnas Tidning. We have established that the conflict between a modernist school tradition and a postmodern society has resulted in a dominant, traditional teacher discourse which is being simultaneously challenged by both a market-orientated discourse and a professionalization discourse. Furthermore, we attempt to highlight how these ?ideal? constructions can create problems in terms of identity construction for teachers.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species. The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

2010 was the year of the wedding between Sweden?s crown princess Victoria and Daniel Westling. Although the wedding was partly financed with tax payer?s money, the newspapers did not investigate it further. The main theme of the published articles was lighter and with an entertainment value rather than finding out what the tax money really went.

The aim of this study is to look how the Social Service has handled custody issues. The study has a legal and social aspect with a purpose to investigate how the law affects the social administration as well as the family. During a period of one year a quantitative and qualitative study was performed within the social administration in a nearby community. The study focus is partly on the relationship between the law, family and society. The main questions have been: Which one of the parents, mother or father, did in fact get the custody and why? How has the children?s point of view been reported in the inquiry? A child needs a well organized everyday life in a preferably conflict free environment.
