The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.

This pilot study describes a therapy method for persons withBroca´s aphasia. This method is based on the mapping hypothesis (Schwartz,Saffran & Marin 1980). The mapping hypothesis is based on the assumptionthat agrammatism is caused by an inability to combine syntactic structurewith thematic roles. This study describes a combination of the therapymethod mentioned above and the Everyday life activities photo series (ELA,Stark 1992). The aim of the study was to investigate if therapy based on awritten sentence/picture format is a viable starting-point for future research.The therapy presented combined written sentences with pictures describingeveryday life activities.

The focus of this essay is Swedish bilateral development aid. With the help of organization theory I analyse the development aid strategies and policies of the 1990s, in order to examine how and why they were introduced. I investigate three different types of aid organization, namely structural adjustment programmes, political conditionality tied to aid co-operation, and equality policy as part of development co-operation. I analyze the introduction and subsequent use of these three co-operation forms to see whether they were applied and adopted into Swedish development aid because more efficient measures were required or because they were the most recent and modern ways of dealing with development co-operation.Organization theory presents these two ways of analyzing organization. They are occasionally competing and sometimes complementing each other in explaining organization.

The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.

This examination paper is a lead in the educational program Industrial Management at Jönköping University. The paper itself contains an analysis of the warehouse organisation and its efficiency at the furniture company Voice AB in Torsvik, just south of Jönköping, Sweden. The report also contains propositions to raise the level of efficiency in the company warehouse and warehouse management.In the investigation of the warehouse a number of possible improvements were found. Examples are lack of a system for labelling shelves and racks, lack of an efficient location system and development possibilities in work routines. For the empirical investigation both qualitative and quantitative methods ware used.

Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Through the ages mankind has developed and tested a cascade of varying weapons ofwar, large and small, and has has striven to push these creations to the limits of theirtime. A grand example of this are the medieval siege engines that have changed shapeseveral times over the centuries. After all this time the eciency of these siege engineswill have reached their peek.

An increasing number of automotive supplier companies are investing in Central and Eastern Europe (CEE) in order to gain cost advantages. This has happened in a rapid pace since many of these countries did not have any foreign direct investments (FDI) at the turn of the century. The problem now is for how long these countries will be able to maintain the low costs. One purpose was to create a model of country advantages for automotive supplier companies when relocating further production to CEE. This dissertation was written in cooperation with the Trelleborg Group.

This thesis aims to examine the possibility of understanding social change by using new institutionalism approaches on a specific case, The case, which describes the implementation of new public management reform in the Swedish health care system, is analysed from two separate new institutionalismperspectives; the tool perspective and the symbol perspective. These approaches differ from one another in the sense that the first relies on a rational choice ontology, while the latter rather refers to a sociological tradition. In the analysis, causal explanations as well as aim related explanations are presented. Formative moments such as economic stagnation, non-socialist governments and ideological isomorfism are presented as important factors behind the reformation. By using the tool perspective, the motives of the idea spreading and reformation of the Swedish health care system, are connected to a strictly rationalbasis such as cost efficiency and quality improvements.

What role does the state play in economic development? This thesis seeks to investigate the relationship between a strong state and economic development. To define the concept of a strong state I focus on the relationship between the scope of state functions and the efficiency of which these functions are implemented. The concept of a strong state is in this thesis defined as the efficiency of the state functions. By using a database constructed by three economists; David Kaufman, Aart Kraay and Massimo Mastruzzi as a measurement of a strong state I test the relationship with economic development empirically.

Previous research in the field of consumer marketing has confirmed the positive effects of divergence on advertising efficiency. Despite the coherent evidence, some industries lag in the adoption of these findings, one of which is the Swedish real estate market. Divergence has not been elaborately investigated within said context and this paper addresses the need of actionable insights for housing advertising. Starting with the proven success of housing firm Fantastic Frank who work with detail photos in contrast to the common wide angle, this paper examines theoretical implications of detail photos' characteristics. Besides being divergent, detail photos are also ambiguous which renders access to effects related to visual perception.

The energy use in a workshop company has been examined in this work in order to find areas for energy Efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
