Nitrogen deposition leads to environmental damage in areas where the nitrogen deposition is high. Southwest Sweden receives an annual nitrogen deposition of up to 20 kg N/ha. Nitrogen that is not assimilated by the vegetation is accumulated in the soil, which may lead to nitrogen saturation and an elevated risk of nitrogen leaching. Nitrogen leaching from forest areas in southern Sweden has proven to be higher than from agricultural areas, which have been thought to be the main contributors to elevated nitrogen levels in rivers and lakes. The amount of nitrogen that leaches depends on the fraction of the total nitrogen in the soil that consists of nitrate, since nitrate is easily transported through the soil.

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

Aim: Auditors objectivity is an obvious part of auditing, but there is doubts and hesitation in society today because of the corporate scandals that have occurred in recent years. Several researchers suggest that auditors actions and behaviors is connected to the ethical climate within the organization. A relationship that also affects auditors objectivity and independence. This thesis aims to investigate how the ethical climate influence auditors choice of relationship to their clients, by choosing a relational and close relationship or a transactional and distanced relationship. And if the client approach have an effect on the auditors objectivity.Method: A survey was conducted among 232 certified accountants in Sweden.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

To produce fine fibre wool as a complement to lamb meat production, Merino and Svea sheep are currently being crossbred in the county of Jämtland. The aim of this study was to evaluate growth and wool quality of the first crossbred lambs. In addition, a literature study about nutritional effects on wool production has been carried out. The literature study showed that fine fibre wool should foremost be achieved through directed breeding. Nutritional requirements of the sheep at different stages of production should determine their feeding.

Bakgrund: Studier har visat sig att barns postoperativa smärta i många fall är otillräckligt behandlad och barnen upplever ofta smärta som något obehagligt och skrämmande. Barn kan påverkas negativt av smärta och de kan utveckla skadliga beteendeförändringar efter en operation på grund av otillräckligt behandlad postoperativ smärta.Syfte: Syftet med den här studien är att undersöka hur barnen, på en specifik kirurgavdelning, mår under det första dygnet efter en operation då de blivit sövda, avseende deras postoperativa smärta. Om möjligt ska grupper som har ökad risk för otillräcklig postoperativ smärtlindring försöka identifieras.Metod: En kvantitativ tvärsnittsstudie baserad på ett konsekutivt urval. Deltagarna består av barn på en kirurgavdelning i åldrarna 4-16 år som alla har genomgått en operation där de blivit sövda. De har fått besvara en enkät om sin smärta ett dygn efter operation.Resultat: I studien deltog 32 barn med en medelålder på 9,25 år.

Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms. This thesis bases on previous work on supply chain mapping and cost theories.

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

In Sweden has the temporary agency work industry settled in an explosive way since the deregulation of the unemployment agency monopole in 1993. The demand of civil right for the employer that is rented out confronts the entire labour law regulation with new challenges.The purpose with this paper is an investigation of the principle of equal treatment in The Swedish temporary agency work act and also to create a deeper understanding of the effects of labour and employment relationship. An investigation of relevant collective agreements will be done to highlight the difficulties the principal of equal treatment is exposed to. Further on is there a will to gain understanding for the wage concept and what possible can be included in the wage concept in relation to the principal of equal treatment in The temporary agency work directive. By using the dogmatic method, an approach to descriptive identifying relevant sources of law and clarify the legal situation in the area.In the conclusions it will be determined that the principle of equal treatment in The Swedish temporary agency work act have different effects depending on if the temporary agency or if the client corporation is tied to an collective agreement alternative if a collective agreement is completely missing.

The electrical grid needs to be changed in the future in order to manage more distributed and renewable generation and also to make it possible for electricity consumers to be more active and aware of their electricity consumption. This future grid is usually referred to as a smart grid. With the transition to a smart grid, new challenges occur. One method to determine those challenges is to perform risk and vulnerability analyses. InStockholm, the new urban district Stockholm Royal Seaport is built.

I de svenska djurskyddsföreskrifterna anges 1,5 × mankhöjden som lägsta takhöjd i häststall. Det har ifrågasatts om takhöjden påverkar djurets miljö så mycket att föreskriften skall tillämpas strikt även i befintliga stall. Motivet till föreskriften är att hästen skall kunna stå i normal ställning och inte slå i taket om den kastar upp huvudet men också för att ventilationen ska fungera på ett bra sätt. Inga objektiva data har hittats i litteraturen om hur takhöjden påverkar hästens möjlighet att stå i normal ställning eller att lägre takhöjd än den föreskrivna påverkar risken att slå i taket. Varför takhöjden skulle vara viktig för att ventilationen ska fungera på ett bra sätt är oklart. För att djurskyddskontrollerna skulle bli mer likvärdiga fick länsstyrelserna ansvaret för djurskyddskontrollerna 2009.

För att optimera sin teknik i olika kastgrenar använder idrottsmän på elitnivå idag mätningar med höghastighetskameror. Kamerautrustningen är dyr och svår att frakta. Utvärdering av det filmade materialet görs till stor del för hand. För att förenkla mätningarna fanns en ide om ett system som baserar sig på givare monterade inne i kastredskapet. Visionen är att bygga ett kastredskap som kan registrera sina egna rörelser under ett kast.

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.
