According to the EEG-councils regulation nr 2092/91, all seed used in organic production must have organic origin. All seed which is offered for sale must be controlled by KRAV, and also comply with the rules of the seedlegislation. The seedlegislation contains demands respecting origin, quality, growingconditions and freedom from deseases. In this piece of work I will investigate the profitability of organic potatoseedproduction, and also what it takes to produce potatoseed. The workmethod has been to, with help from counsellors and growers, make some compareable calculations for foodpotatoes and seedpotatoes, and also with help from a literaturestudy investigate which requires an organic seedcultivation must fulfil. In this piece of work I found out that the organic potatoseedproduction still is to insecure to be profitable. The attack of potatoleafmould, which is out of control, cause unequal yields and this will bring that the new EU-rules, concerning organic seed, not seems defendable yet..

In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.

The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB.  The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.

The swedish song contest ?Melodifestivalen? is the most popular TV-show in Sweden according to number of viewers. Not only has it managed to remain the viewers? number-one choice year after year, it has also engaged a lot of the viewers (2, 4 millions in this year?s final) to vote for their favourite song. Melodifestivalen is classified as a creative organisation since it has evident elements of creativity in its process, product and among its employees.

The aim of this thesis is to examine the customer profitability in a wholesale company. A case study of Eugen Wiberger AB has been conducted. Firstly the authors have examined the current perception of the company regarding their customer profitability and the results of their calculation of the customer profitability. Secondly an Activity-Based Costing analysis has been performed and has been compared to the perception in the case company. The conclusions are that the smaller customers are the least profitable, and in some cases unprofitable, whereas the larger customers are profitable.

This thesis is about a potential trade-off between integrity and long-term usability in the choice of file formats for preservation of text documents. Five common formats are discussed: plain text, PDF/A, Office Open XML Document, Open Document Text, and Markdown. The formats are compared with respect to four criteria related to integrity and usability and to the records continuum model: support by widely used software, stability, rendering of contents and reusability.It is concluded that no single format is optimal with respect to all four criteria, when it comes to preserving typical documents in a modern environment, with more or less complex formatting and document structure. Therefore, the feasiblity of using two or more formats for preservation of a single document (e.g. PDF/A combined with Markdown and/or Office Open XML) is discussed.

Syfte och frågeställningar Studiens syfte var att undersöka om utförandet av en isometrisk bålstabiliseringsövning/coreövning kunde påverka upplevelsen av smärta i nacke, axlar och skuldror hos kvinnor med kronisk/långvarig idiopatisk smärta. Studiens frågeställningar var: Hur påverkar utförandet av övningen ?plankan? upplevelsen av smärta i nacke, axlar och skuldror hos deltagarna? Förändras den maximala uthålligheten i övningen mellan deltagarnas första och sista träningstillfälle? Kan interventionen fullföljas av deltagarna?Metod Fyra kvinnliga deltagare som alla hade kronisk/långvarig smärta i nacke, axlar eller skuldror utförde övningen ?plankan? som hemträningsövning under fyra veckors tid. Mängden träning dokumenterades i en träningsdagbok som deltagarna kontinuerligt fyllde i under träningsperioden. Före samt inom en vecka efter träningsperioden ifylldes en enkät med frågor om upplevd intensitet, frekvens och lokalisation av smärta.

This report is the result of a project work carried out at Karlstad University in conjunctionwith the local consulting firm Camatec where most of the work has been performed.The work can be classified as a classic engineering work with supportive theories andcalculations which in this context is relevant.The engineering project has focused on developing new standards for a conveyor that is usedin the Värmland paper industry where large rolls of paper are produced. A conveyor can takeits appearance in many different forms but in this thesis it has been an exemplary look and ithas also become modulatable with a central section, a drive end and a turning end.The construction work has been build under CAD programs such as Pro Engineer, drawingshave been created and costings have been analyzed. Strength calculations have been made andcooperation from several different companies have erected to explore different solutions andideas for a modern and sustainable conveyor..

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

To increase the quality in their products ABB is working towards a cleared order concept. That means that all customer specified options are to be known before they start with order calculations and construction. As it is today they use paper checklists to achieve this. One order may have several reactors, and for a reactor there can be several different alternatives. For each alternative a new checklist must be filled out.As of today all reading of the customer specification and checklist fill in with is done by hand by different persons, and sometimes the same data is read more than one time.

The purpose of our thesis has been to study Social Workers view of children?s needs and how they work with children?s needs when they are orphaned because of HIV/Aids in South Africa. The question formulations we used to answer our purpose are:? What needs do the Social Workers consider the children to have?? How do the Social Workers work with children?s needs?We have a qualitative methodological approach in the thesis, where we have performed four interviews with four Social Workers on different organizations in and around Cape Town, South Africa. The presentation of the empirics is made as a summary with representative quotations, which we have interweaved with earlier research and theoretical conceptions.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

When a child is hospitalized, it is usually more than one person who needs attention ? i.e. the child as well as its parents. The emergency ward environment and surgery rooms are unfamiliar and the parents feel anxious, insecure and uncertain about how to act. They are expected to participate in the child?s care, cope with their own anxiety and simultaneously convey a sense of security and stability to the child.

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.
