Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Working Model of the Child Interview (WMCI) är en metod utformad för att bedöma och klassificera föräldrars förmåga till omvårdnad utifrån beskrivningar av förälderns subjektiva upplevelse av och relationen till sitt barn. Föräldrars inre representation av omvårdnad har visat samband med barnets förmåga att skapa en trygg anknytningsrelation. WMCI har visat stor användbarhet både i forskningssammanhang och i klinisk verksamhet men är tidigare inte prövad i Sverige. Syftet med denna pilotstudie är att pröva metodens användbarhet på en svensk population. Tretton föräldrar, sex pappor och sju mammor, som är förstagångsföräldrar till fullgångna och för tidigt födda barn har intervjuats med WMCI.

This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.

Energy awareness is growing among the Swedish population and a one­?to­?two-family dwelling can save energy. The purpose of this paper is to design a tool that helps these home owners reduce their energy costs.The paper develops a model that gives them an indication of how much energy they can save. For the majority of homeowners, the next step in the quest to reduce theirs is most likely an energy audit. Therefore, information to help home owners to get a good energy audit performed is included in the model.A prototype running the operating system iOS is created and validated against existing models, as well as an energy audit. .

Syftet med studien är att undersöka vilken affärsmodell som born globals använder vid internationalisering och vilka faktorer som påverkar valet av modell. Studien har använt sig av en kvalitativ forskningsmetod och har genomförts som en fallstudie. Vidare utgörs studien av semistrukturerade intervjuer. Studien kommer fram till att born globals vid internationalisering har en affärsmodell som a?r freemium och att det resursbaserade synsättet samt bransch är viktiga bakomliggande faktorer till valet av affärsmodell. Faktorerna globalisering och entrepenören har mindre direkt påverkan medan nätverk endast har en begränsad påverkan i valet av affärsmodell för born globals vid internationalisering. .

The main purpose of this analytic study which has a theoretical focus, Is to find out if the two Swedish parties Socialdemokraterna (s) - The Social Democrats - and Folkpartiet (p) - The Liberal Party - has taken position ideologically or strategically to the new sex-degree grading scale. The theory section describes the concepts of ideology and strategy. Despite the talk of the death of the ideologies, this don't need to be the case, they only adjust över time. The second key-point of this essay is strategy, a model based on Frostbergs reasoning illustrates this. A number of problem areas are presented.

My essay is concerned with intercultural leadership and practical knowledge. The essay is about ethical dilemmas and the diversity of issues we face constantly at the preschool. In my story I examine the different views of knowledge and the opportunities to lead people in an intercultural way, and how they relate to each other. I start by looking at the ethical ideas that form the basis for our actions and our view of knowledge. Then, I examine how the practical wisdom guides the ethical dilemmas that arise at the preschool.

ABSTRACTThe study is an analysis of the politic debate about the decentralising of the public school between the years 1946 and 1990. The problem that the essay is about to study is which reason made the decentralising take place. The texts that have been read, interpreted and reconstructed are propositions, motions and written debates in the parliament. The purpose of the study is to examine the discussion about the schools decentralising in 1946-1990. The aim is also to examine what kind of pro- and contra arguments that are shown in the debate and who the interveners are and why they made a statement.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

Abstract Title: Enabling Smart Research and Development through Knowledge Conversation Seminar date: 2005-06-08 Course: Master thesis in business administration, 10 Swedish credits (15 ECTS) Authors: Andreas Johnsson, Johan Rosendahl Advisors: Lars Bengtsson Key words: Knowledge management, Knowledge conversation, Research and development, Ba, Trelleborg Purpose: The purpose of the thesis is to create a model that shows how knowledge management aimed at research and development processes can be used and how the theoretical fields can be connected. Methodology: The thesis is based on abductive perspective where empirical and theoretical material has been mixed to create a foundation for the analysis. Theoretical perspectives: Theories concerning knowledge management and research and development have primarily been used. These have been complemented with material about team structures and incentive systems. Empirical foundation: The empirical material is based on semi structured, mostly qualitative interviews and strictly quantitative inquiries performed at Industrial Hose within the Trelleborg group.

In this qualitative study the authors explores, by studying several quality-development models what quality in leadership is. The models are: Total Quality Management; SIQ?s model for customer-oriented organizational development; the EFQM excellence model; the ISO 9000:2000 standard; and Six Sigma. These models will be compared from Deming?s list for upper management; the Situational Leadership Theory; and the Contingency Theory.

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

The main focal point of this study is about public libraries and its possible roles in today's society. Going from having had a clear educational orientation, public libraries has with time amassed several other roles, which all need to relate to the swedish law regarding libraries and other governing documents, as well as business plans. This thesis focus on a qualitative investigation, which was conducted through in-depth interviews with librarians and other staff at a public library in Stockholm, named bibliotek Plattan, to ascertain the prevailing opinions within this facility about the role of libraries and librarians. The choice of examine this particular library was based on the fact that bibliotek Plattan differs from the public library in general and only offers material for adults. Their collection of litterature is primarily based on fiction novels.

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.
