This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

To be able to secure a safe and reliable power supply is becoming increasingly important since society depends on services and functions that need continuous power supply. The delivery rate in Swedish power supply is 99.98 % which insists on a high availability. During the past decade several storms has passed Sweden which resulted in large amount of tree felling leading to extended power outages. During these storms many socially critical activities, such as electric utility company Fortum, experienced disruption in mobile communication which affected the crisis management. This paper has investigated Swedish mobile operators? crisis management at Hi3G, Tele2 and TeliaSonera with a case study of the storm Dagmar that hit Sweden during December in 2011.

This thesis analyses the 2005 UK presidency of the Council, and more particularly the negotiations on the future financing of the European Union. The purpose of the study is to discuss whether the holding of the presidency implies political influence for the member state. To analyse the power of the country holding the chair the thesis focuses on the presidency functions of brokering and leadership. The theory suggests that the influence of the presidency is derived from informational and procedural power resources, as well as some leadership resources, such as coercion and reward. A case study was used to analyse whether these power resources were used by the British presidency.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

During the last few years, there has been a lot of debate regarding the price ofelectricity on the Swedish market. According to a recent survey from Sifo, anon-bias governmental institute for consumer research and testing, the priceof electricity is what worries Swedish households the most. An investigationof the eciency of the Nordic power grids inuence on the Swedish spotprice is therefore both relevant and valuable. Three quarters of all electricityproduced in the Nordic region is traded at the Nord Pool Spot power market.This survey examines how much of the variation of the swedish spot pricecan be descried by the variation of the nordic system price and how much iscaused because of ineciencies in the power grid. Primarily, linear regressionwith adjustments for endogeneity and heteroskedasticity has been used in orderto analyze data obtained mainly from Nord Pool Spot and Vattenfall AB.The results show that the variation of the system price can account for all butabout 40% of the variation in the Swedish spot price.

Background: The recent years in the Swedish Fast Moving Consumer Goods industry have been characterized by a palpable shift in power balance, favouring the retailers. Since the shift in power balance has strengthened the negotiation position of the retailers, the suppliers now have to, to a greater extent than before, accommodate to the retailers? goals, whether they be financial or strategic. Purpose: The aim of this study was to investigate how this recent power shift has affected the relationships of suppliers and retailers. This development has resulted in the rather new and unexplored area of retailer value, which this study further aimed to explore.

The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

ABSTRACTUniversity: Växjö University, school of social science, department of political scienceLevel: Bachelor?s thesis in political scienceTitle: SHIFTING BALANCE OF POWER? ? an analyze of the new EU-treaty?s consequences for the EC-court.Academic adviser: Associate professor Stefan HöjelidAuthor: Magnus NordahlThis study focuses on the increased role of the European Court of Justice through the establishment of a Constitution for Europe and its impact on the balance of power, both horizontal and vertical.To do this, the study takes its aims from the research problem, formulated as follows:Does the establishment of a constitution for Europe contribute to an increased role for the European Court of Justice and does it create a more legible horizontal and vertical division of power?To reach the relevant analyses and conclusions two precise questions are presented as well as an analytical model. The precise questions are:? Which are the relevant contributions for the balance of power from a perspective of juridification in the new EU-treaty?? What impacts do those contributions have on the so called ?European federalism??The theoretical perspective of this study is rooted in the concept of federalism with special emphasizes on constitution and sovereignty as well as a part about the process of juridification. Along with the presented analytical model consisting of a horizontal and vertical division of power, the empirical material is presented with focus on the new EU-treaty about a constitution for Europe and the European Court of Justice.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

People with certain types of disabilities have the legal right to ask for an individual plan. The idea is that the plan should be a tool for the disabled to get more power and influence over the planned actions that involves their lives. The aim of this thesis was to study the individual circumstances of interpersonal power and influence in the work of individual plans. The study was done with a qualitative approach, where three executing officers and three individuals were interviewed. The results show that the conditions for the individual?s influence are far more complicated than at first glance.

The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
