This work is a part of the project ?Våtmarker i odlingslandskapet ? uppföljning av miljömålen? (Wetlands in arable land ? following-up of the environmental goals). The main objective with this project is to study nitrogen and phosphorus retention in a constructed wetland by using mass balance calculations. Continuous measurements of nutrients and water flow through the inlet and the outlet of the wetland are made. However, substantial amounts of nitrogen and phosphorus were assumed to reach the wetland with a drain-pipe transporting wastewater from nearby houses (10 persons).

Today's technology offers a variety of opportunities to interact with the interactive systems. Human-Computer Interaction in the last decade is the area of research that has contributed the most to this development. But how is this interaction perceived? The user experience is something that is formed by the interaction between human and the computer interactive systems. The objective of this thesis is to investigate how the user experience differs depending on how one interacts with a game.

Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.

For Swedish companies to compete with low wage countries, developments in theproduction industry moved towards streamlining the entire company. One of themost effective ways for a company to streamline their operations is to review theirproduction. All companies have processes in their production that add no value tothe product. In order to compete, they must be eliminated.The purpose of this report is to reduce work in process (WIP) in the flow ofbashus at Volvo Powertrain in Köping. The aim is also to try to find reasons whyVolvo Powertrain feel that they have problems with the storage principle First in-First Out (FIFO).To meet the objective, empirical studies were conducted at the company whilethe literature in the area was studied.

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.

At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

Logistics is an important concept in the organizational context in which the planning of flows, services and products are treated. Logistics handles supplier management, supply of materials, production and distribution. The distribution of goods can be managed with different types of transportation depending on price and time aspects. The lowest transport cost for larger amount of goods is by maritime shipping. A common carrier used in transportation of goods is a standardized ISO- container.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

The purpose of this study was to examine the foreign news flow in Sweden´s largest news agency TT. Since TT has an important position as a news provider to most of Sweden´s local and national news outlets, it was important to examine exactly what their news stories consisted of.The theoretical background of this study consist of theories of news values, agenda setting, dependency theory and the theory about the ?news shadow? a lack of coverage leads to.In our quantitative study we have looked at 506 articles taken from the TT news flow during two weeks In November 2013. We have studied which continents and countries the news origins from, who have supplied the text, the topics of the news, which one gets to speak in the text and what general tone the story has.The study shows that the supply of news follows the criteria of news values. It also shows that in some regions of the world the coverage is almost nonexistent.

The aim of this study is to examine the collection One Thousand and One Nights (also: The Arabian Nights) from a european perspective, by comparing different european translations. The study focuses on three translations into Swedish from different periods of time and how the tales have changed in the translation process - depending on the prevailing line of approach and Western perceptions of Eastern standards. The thesis of the study is that Eastern culture, from a Western perspective, has been seen as exotic and different but not as a high literary culture and that this view has affected the translations into european languages. The study shows, among other things, that Western culture is many times considered normative in the translations and that the translators often give their own voices a prominent role, also that common Western notions of the East affects the translations.The word ?orientalism? is used frequently in the study and it refers primarily to the image of the Orient as it is described in Edward Saids' book Orientalism: as a Western construction whose main purpose is to strengthen its own conception of the Orient and thereby strengthen the Western identity as better than the Orient.

Saab Component Maintenance in Linköping, Sweden, offers maintenance, repair andoverhaul (MRO) services for civilian and military aircraft components. Lately, thedepartment has struggled with slow throughput rates, despite various counteractingattempts. Studies show, that large parts of the delays derive from the logisticsdepartment where goods arrive and dispatch. Therefore, Saab wants to carry out anextensive analysis of the department in order to further investigate what is causing itsslow throughput rates.The thesis begins with extensive mapping over Component Maintenances whole valuestream to find out how departments interact with each other and which roleindividual departments have in the total supply chain. Out of 13 000 different partnumbers, components were divided into five product families.
