High levels of ammonia in grass silage have been up for discussion by Swedish advisers. One reason is that it is more difficult for the rumen-microbes to utilise high levels of ammonia. A low level of ammonia is also good because if the cattle can use more of the protein in the silage, they don?t need so much protein concentrate. That is very good for the economy at the farm, and it is also good for the environmental problems caused by high levels of ammonia. In this project, 24 samples of silage have been taken at 20 different farms in the south west of Sweden.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The main aim was to investigate the provenance of Viking age antler material findings of moose and red deer from Sigtuna and from three sites on the island of Gotland in the Baltic sea. This was done by analysis of the stable isotopes of carbon, nitrogen and sulphur. Thre were never any living population of these mammals on Gotland during the Viking age.?34S-values of sulphur from this study was compared with earlier research and by studying maps of the Swedish bedrock. The ?34S-values were more like the ?34S-value for bedrock other than European granite.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

The law firm industry has during the last years met new demanding conditions and one tool to handle these new conditions has been to implement a Knowledge Management system. Large investments have been made in these Knowledge Management systems but the implementations have met many challenges from within the organizations.With a multiple study, based on interviews with Knowledge Management Managers included in a Knowledge Management network, this thesis aims to study the challenges with Knowledge Management and the underlying causes. The result, based on McDermott's theories shows challenges within technical, personal, social and management areas where the law firm need to shift a focus from Information to Knowledge Management, create a culture of trust and integration and use the informal powerbase.The causes for these challenges are found in the base of Mintzbergs theories of Professional bureaucracy where the Knowledge Management is affected by strong self-regulated individualist, a divided organizational structure and industry conditions..

The purpose of this study was to identify the positive and negative aspects of the work and dynamics of a management team and from that recommend how the team can improve. The aim was also to investigate whether there was a gap between how the members of the management team comprehend themselves and how the project, section and team managers comprehend the management team. The management team contains of seven core team members and is the head function of a research and development site in central Sweden. The results are based on interviews with the present members of the management team and three former members, a survey among the project, section and team managers and by participating observation on meetings with the team. The results show that the management team is an overall well-functioning team that with some changes and improvements, especially concerning communication and information, can reach even further.

1. Reaction on burial depth and nitrogen availability and placement in competition with a crop In this trial it was investigated how couch grass (Elymus repens) changes its ability to compete in stands of wheat and barley with different burial depth and different amounts and placement of nitrogen. More knowledge in this area can be valuable in the attempt to decrease the use of herbicides and still keep the weeds under control. The trial was carried out in the summer of 2004 as an outdoor pot experiment. The pots contained 15 litres of soil with a surface of 0,06 m2.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

The public service within health and care has changed remarkably during the last 30 years. It has been inspired by management ideas from profit-making businesses. Those thoughts are an umbrella term called Nex public management. In what way has New public management influenced the public service in Sweden? Important concepts in the change of public service are quality, effektivity and goals.

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

The purpose of this essay is to investigate if the companies listed on Nasdaq/OMX Stockholm Large Cap use the earnings management phenomenon Big Bath Accounting to a greater extent when a change of management (CEO) is made.Management tends to use earnings management when there is a bonus plan linked to the result of the company. To gain maximum bonus the management will try to manipulate the result in a way that in a long term maximize their utility. Through the earnings management technique Big Bath the management is given the possibility to take one large cost as a one-time expend, even though the cost is supposed to run over several financial years. This, of course, within the legal framework. A big bath may occur when there is an impairment of goodwill, tangible and/or intangible assets or larger provisions for future expense, or both of them at the same time..
