Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.

This report is the result of a thesis as been implemented during the spring term 2009 atthe University of Gävle.The company Bruks produces mobile chippers which are used for chipping loggingslash, roundwood and parts of trees. The chipper is powered by a separate diesel engineand the chipper can be assembled on trucks, trailers or some other carrier vehicles.When the chip has passed the chipper drum, the chip is collected in an integrated binwhich is mounted on the vehicles frame with dumping yokes. When these dumpingyokes were designed they were probably created with large material dimensions. Theaim with the degree project is hence to study the strengths of materials and, if possible,to suggest an arrangement that can decrease the total weight on the dumping yoke onBruks´ mobile chippers 805 CT.The CAD-program Pro/ENGINEER was used during the project for outlining the 2Ddrawings,as distributed of constructors on Bruks, to solid 3D-parts. The three-dimensionalassembly from Pro/ENGINEER was transferred to Pro/MECHANICA.

This report explains how different communication tools can be used in a company?s intranet. It gives a short description of the different parts in an intranet and their field of application, and what communication means. It?s only the communication tools that the company uses that we are illuminating in this report.

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

The purpose of this thesis is to discuss education as a state tool in Sweden during the 17th and 18th century. The idea is to contrast the pragmatics of the Swedish education system with the theories of Rousseau and Comenius. The thesis is marked by the thought that theory and application diverse because of the subversive infusion in the ideas of the theoretic.The results shows that it is ultimately a question of public education and its potential. The state recognises the potential of public education but also its dangers and therefore becomes very active in forming not only the education system as a hole but also its pedagogic.

The aim of this master thesis was to examine the European Commission's information resources from a user perspective in order to clarify the needs and circumstances of the search of EU-information among students at Örebro University. 41 students participated in a survey, and four of them was interviewed. On the basis of Pendelton- and Chatmans theories of information behaviour in small worlds, it were assumed that the students' education and citizenship in the European Union affected their needs and the search of EU information.The study showed that the students needs for EU-related information has increased, with the current education, but also been linked to earlier educations. The students Citizens need were mainly associated with elections such as the EMU-election, but also in some cases to a need of the general knowledge.A review of the European Commission's information resources were made with an emphasis on European Documentation Centre, EDC. The survey showed that most students used the EDC and the EU-databases that was made available by the European Commission through the EDC and the university library but were not aware that they used EDC.The survey also showed that students made use of familiar sources and resources when they searched the EU-information, such as the library's regular database list, the library catalogue and search engine on the internet are not requested of other resources.

Pomace is the solid remains (i.e. stems, pulp, seeds, and skins) after pressing for juice. The annual production of apple pomace is 593 000 ton worldwide. Its field of application depends on local conditions. In order to investigate the field of application of apple pomace in the Southern Sweden, six persons on companies with production of apple juice were interviewed.

This text concerns itself with war, the just war theory, and the application of that doctrine on the ?war on terrorism?. I present different views on the theory's place in the discourse, its relevance for unconventional wars followed by the analyses of above mentioned empirical situation.Particular interest is given the criteria concerning proportionality, both ad bellum and in bello, due to in part its difficult nature, and the attention it has received from others. This paper asks the question: Is the just war theory adequate for analysis of modern war?There are few alternatives.

Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

This 3d navigation application is a part of a project that helps the user to learn and find the right position on a map with many exercises, the user has a compass nearby that he/she can use to find the position that requires to get the right answer on that particular exercise. Macromedia's Director is used for the creating of the program, where Lingo has a importent part as the script language for the scenes in Director. A 3D scene is build up with codes in Lingo, a few 3d models and serveral overlays are created and displayed on the screen. Different kind of textures from pict files are is representing the overlays and put on the 3D models. That give the user a more pleasant experience when going through the exercises that helpes the user when he/she is going to navigate on a boat at sea..

The goal of this project was to implement and compare Invere Discrete Cosine Transform using three methods i.e. by bit parallel, digit serial and bit serial. This application describes a one dimensional Discrete Cosine Transform by bit prallel method and has been implemented by 0.35 ìm technology. When implementing a design, there are several considerations like word length etc. were taken into account.

This thesis focuses on employers? use of non-­?solicitation of employees in commercial contracts within the union?s internal market and how this can result in restrictive practices in violation of European law. Using legal method, legal economic considerations, and guidance from modern American legal development in antitrust law, this thesis is aiming to investigate how this kind of anticompetitive cooperation in the European labor market should be assessed. The result seems to be that despite a distinct and pronounced restrictive approach to the application of EU competition rules in the labor market, there are strong incentives and not any legal impediment to apply Article 101 TFEU on no cold call agreements between employers. .
