The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

The increasing public concern regarding the government?s priorities in spending public resources puts pressure on public organisations to address quality issues in their practice. In United Kingdom both BRTF (Better Regulation Task Force) (BIS, 2005b) and the Hampton report (BIS, 2005a) highlighted management and quality problems in public organisations in UK. These reports revealed obstacles within institutions? intent to offer recommendations and appropriate solutions for agencies working with legal enforcement and control.

Syftet med vårt arbete var att studera vilka övningar och arbetsmetoder en amerikansk skola använder för att förbättra elevers muntliga framställning. Den empiriska delen av vår undersökning genomfördes i en amerikansk skola med 20 elever i åldrarna 12-13. Observationerna genomfördes i ämnena performance, council samt speech. Studien var av kvalitativ karaktär och genomfördes med ostrukturerade observationer. Vi kände snabbt stor skillnad mellan de svenska skolor vi besökt tidigare under vår utbildning och den amerikanska skolan beträffande elevernas vilja att tala.

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

It gets more and more important for companies to get involved in Corporate Social Responsibility, CSR, when stakeholders now are more aware of the responsibility companies should take. Through their communication companies show how they take responsibility. Reflected by their goals by which they want to achieve acceptance and understanding through an open dialogue. The paper examines this issue. CSR is an abbreviation for Corporate Social Responsibility which is engagement in responsibility for companies and organisations.

Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol. Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.

Through extensive research it has shown that today?s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today?s market. Besides rising fuel-costs, environmental awareness is very important in today?s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University.

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

In this study the speech of adolescents with unilateral cleft lip andpalate (UCLP) and delayed closure of the hard palate was evaluated.Evaluations were made with experienced speech-language pathologists(SLP:s) and lay listeners. The SLP evaluation consisted of typical cleft palatespeech variables and some of them were adapted for lay listeners. Attitudestowards the speech of the adolescents were investigated by asking laylisteners if the speech constituted any hindrance to vocational performance.The SLP:s mainly found nasal escape and velopharyngeal impairment (VPI),although to a small degree and extent. The lay listeners mainly foundresonance deviations and indistinct speech. The latter was associated withhindrance to vocational performance.

This study aims to examine how performance management is compatible with the operations at Sida, Sweden?s International Development Cooperation Agency, by performing interviews with representatives from Sida. The public sector is facing increased demands on accounting, which has emerged as an institutionalized social norm in society. The nature of Sida?s operations, however, proves to be highly complex, rendering results based management difficult to implement.

Because of an increasing demand from customers and changing external environment, there is a need for continuous improvements, for both manufacturing and service organizations, to meet these demands. Manufacturing organizations have been working systematically with quality improvements for a long time, but it has not been as common for service organizations. Because of that the methods to use for implementation of the systematic improvements have not been designed to fit service organizations, and not either for public organizations. The purpose of this thesis is to explain if and why the Swedish Road Administration?s organizational culture and handling of ideas and deviation support an implementation of continuous improvement management.

The environmental monitoring in Sweden has been developed by several different parties and is now being coordinated and made more effective in order to meet the current demands on high quality information regarding the state of the environment. Sweden has been divided into five different water districts based on watershed areas because of requirements in the Water Directive of the EU. In Sweden there are two common types of environmental monitoring programs used to gather information on changes in time and in space. Currently both these two types are used for lakes in the water district of the western sea but only one is used for watersheds. The purpose of this report is to supply basic information regarding the possible need for a second environmental monitoring program for watersheds in order to better describe the spatial variation within the district as well as to determine the number of samples necessary in order to describe the district over time and space.

This thesis aims to explore the use of costumed interpreters at museums. Firstly the thesis examines how extensivethe use of historical costumes is in Sweden, along with some international comparisons. Later on the differentways that the clothes are used is examined, and the costume as a resource for learning is discussed. In the lastpart of the thesis the ?function? of the costume is examined.

A growing number of Swedish forest owners are choosing to certify their forestry. However, there appears to be a lack of field surveys which describe differences between certified and non-certified forests concerning the degree of completed environmental considerations. In order to know to what extent certified forests contribute towards improved environmental consideration, we need studies on how large the difference is in relation to non-certified forests.Differences between certified and non-certified forest clearings were quantified through an inventory of the number of retention trees, dead trees and snags. The result showed that the retained number of the investigated parameters varied greatly between individual clearings, regardless of certification status. However, the results suggested that the certified clearings had an average higher incidence ofthe investigated parameters.
