This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

Background: From the beginning of the 60´s until the beginning of the 80´s the swedish local government has expand enourmously. The expansion didn´t lead to any discussions about how the local government should be controlled or organized. The local government should instead be organized and controlled as administrations. Lately it has became more usual to have these discussions about how local government should be controlled and organized. Nowadys it´s not unusual that local governments imitate private companies.

This paper is a Master thesis for the Master?s program in International and European Relations in the Department of Management and Economics at Linköping University. As the title indicates, the aim of this thesis is to make a comparative analysis of the conflict resolution initiatives that were employed in the Sierra Leonean and Liberian conflicts. The research questions are: ? What were the root causes and trajectories of the Sierra Leonean and Liberian conflicts? ? What were the conflict resolution initiatives employed in resolving both conflicts? ? Why did the Lome Peace Accord succeed in the case of Sierra Leone whilst the Abuja Peace Accord failed in bringing peace to Liberia? In order to answer the afore-mentioned questions and fulfil the aim of this paper, a qualitative research method has been chosen.

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

Picropodophyllin (PPP) is an analogue of the anti tumour lignan podophyllotoxin with the unique ability to selectively inhibit the receptor of Insulin like growth factor 1(IGF-1). IGF-1 is believed to play an important part in development of the endometrium facing implantation. With PPP treated mice, studies can be made to measure gene expression from tissue of both treated and untreated mice to compare the role of IGF-1 regarding ovulation, implantation and receptivity. The aim of this study was to analyze gene expression of some steroid hormone receptors and cytokines in ovaries from mice treated with PPP. In this study, seven mice were treated with PPP at different times and tissue was collected.

After the tsunami disaster in December 2004 many arguments were heared that one oft the major reasons behind the poor Swedish effort connected to the evacuation and health care of the Swedish citizens in Thailand right after the incident is the Swedish model with independent government authorities. By comparing the constitution, the political decision making tradition by the ministers and the handling of the catastrophe in the tree Scandinavian countries Denmark, Norway and Finland, plus analysing the behaviour of the Swedish foreign and prime minister from a rational choose inspired individual decision making theory the research shows that there is no proof that a constitutional change in Sweden into the traditional model with government authorities controlled by the ministers alone would led to a more effective crisis handling by the government due to crises concerning Swedish citizens out states. Although the research shows that the constitution and the tradition of decision making in the government provides the basic condition of the ministers individual rational decision making.

Social media provides, as many points out, new possibilities for marketing. Marketing in social media requires a two way communication, rather than the traditional marketing where the communication model is typically sender ? receiver.To create a marketing campaign that is suitable for a two way communication model has its difficulties and risks as well as its opportunities. Opportunities in the sense that the campaign can become a viral, a Word of mouth and create a Buzz, which will reach potential customers, to a bigger quantity for lower costs, with a message that will make a different impact from the types of commercial messages we are used to. Risks in the sense that the message, if not properly aimed and phrased, can be turned overnight into something that humiliates the company and possibly harm its brand.The difficulties in creating such a campaign is to create something that will catch people?s attention, discuss and forward it, while at the same time avoid getting hurt.We aim to describe the internet from a cultural context, and from that point of view explore the types of misunderstandings which often seem to happen when a corporate message is created and sent out in social media, how to avoid putting the image of a company in danger when doing this, and examine if there is ways to know how the message will be received.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

The purpose of this study is to investigate how six students at a Secondary School describes interaction patterns among teachers when students express in a way that the teacher perceives as racist and/or xenophobic, by presenting a qualitative interview study. The interviews were analyzed by two opposing models of value education: the traditional and the constructive model.The results show that students divide teachers in different categories based on five qualities: 1) they listening, 2) they accept students' opinions, 3) they allow discussion, 4) they are knowledgeable and 5) they can express their own opinions.These qualities are included in the value pedagogical model for deliberative conversations, whose strategies for interaction aim to create an understanding of different rules and values, thereby creating skills of rules by using a democratic approach. In contrast to this model, the rule-based moral education, in which the teacher uses his authority and refers to rules without giving an explanation for why they occurred, as strategies. .

Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.
