The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

The purpose of this study is to answer how teachers look at diversity in groups, with learning in focus. For this study I chose different high-schools in Sweden teaching Moving Pictures, in Swedish 'Rörlig bild'.These are the research questions: 1) What advantages and disadvantages do the teachers see with homogenity and heterogenity in their groups? 2) Which ascpects of teaching do the teachers bring up when talking about diversity?The method of this study has been a qualitative analysis and investigation in questionnarie form, with qualitative questions. Teachers were asked and data was examined with help of theories in diversity, group work, group dynamics, homogenity and heterogenity by authors like Toseland, Jones and Gellis (2004), Forslund Frykedal (2008) and Hammar Chiriac (2008).It is noticable that the teachers thought of differences in terms almost exclusively of school ability. The result is: - As a whole: homogenity means security, heterogenity means creativity.

Previous studies have shown positive results on the use of music as postoperative pain relief. Quantitative studies have examined the effect of music on rated pain and otherparameters such as anxiety, relaxation and blood-pressure. The purpose of this study was to investigate the expectations and experiences of patients and nurses onimplementing music as postoperative pain relief in an orthopedic unitQualitative design and semi-structured interviews were used to examine expectations and experiences. Five patients and five nurses in the unit were interviewed.Four themes developed during the data-analysis. These themes were ?Expectations on music as postoperative pain relief?, ?Experiences of music as postoperative pain relief?,?Effects of music as postoperative pain relief? and ?Continued implementation of musicas postoperative pain relief?.

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.

The corporate opportunity doctrine constitutes a prohibition for the directors and officers of a company to pursue for themselves any opportunity which falls within the scope of the corporation?s business. In Swedish law the doctrine has not yet seemed to attract any greater attention. This doctrine has been the focus of a multitude of cases in a both American and English law, however mainly in the America law. Therefore, the American legal framework can serve as guidance in trying to define the doctrine as it has developed, or perhaps more correctly not developed, in national law.The perhaps most crucial question to be answered in the area of corporate opportunities is how the law indentify an opportunity as a ?corporate? one.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Total mixed rations (TMR) and TMR complemented with individual grain feeding to dairy cows are a growing practice in Sweden. This is because the heard sizes of the farms are increasing. Some farmers and farm advisors in Sweden have great knowledge and practical experience of working with TMR. In the same time there are many advisors that do not know how to handle TMR and farms that have a group based feeding of their animals. In this MSc thesis, the knowledge of farmers that use TMR and advisors with lots of experience of TMR are gathered, with the aim to create a guide book for advisors that are about to start or just have started working with TMR.

In this essay, I intent to examine history as a school subject in Swedish compulsory school (for children aged 7-16), it contains mostly an analysis of the syllabus for history in the three latest curriculums Lgr 69, Lgr 80 and Lpo 94. The main purpose of the essay is to illuminate the development and the change history as a subject has gone through during this specific time, and my will is also to illustrate the view on knowledge and learning that is revealed in the syllabus for history in today?s curriculum (Lpo 94).The survey shows that in Swedish compulsory school, history as a subject has changed significantly. During the examined years, the contents have been exceptionally broadened and that has lead to increasing demands on the students as it has gone from being directed to the individual and its contiguous history with shorter outlooks on the rest of the world, to requiring the individual to be able to see and understand other parts of the world and different time, on the basis of it?s own history and culture.

To the world you may be one person, but to one person you may be the worldThese words sum up my account of social worker expertise. How does one become skillful?a master?in the profession? I answer this question by exploring how social worker proficiency can be developed and grow with the help and support of supervisors, clients and colleagues. Development through professional supervision and in the encounter with clients is an essential part of the work. I also discuss what it means to be new in the field (a novice) in relation to being experienced (a master).

The aim of this bachelor thesis is to investigate how one independent senior high school without a school library regards the role of school libraries. (What is their view of information literacy? Do they manage to reach the goals of Lpf 94 and the goals of each school subject without a school library of their own?). We have chosen to interview the principal and two teachers. Our major findings are that the public library in our study has been given the role of a school library, a role we think it can not fulfil.

My aim with the experience-based essay is that I want to explore the implications of mathematics on children's development. I also want to examine my approach in relation to the various mathematical tasks. Why do we think that mathematics is important for pre-school children? What does the research say about how the teacher is thinking about mathematics? Can the teacher combine playing and learning and create meaningful moments and activities related to mathematics? I also want to explore our policies and the objectives that the teacher should relate to. What is required of me as a teacher in order to meet those goals?My essay is about mine and my boss?s view of the mathematical tasks that I usually perform in the preschool.

Begreppet tempo har en central roll i dagens manöverkrigföring. En av förutsättningarna för ett högt tempo är underrättelser som ger chefer erforderligt beslutsunderlag.De förband och chefer som nyttjar manöverteorin i sin krigföring strävar ständigt att utveckla sin förmåga till väpnad strid enligt manöverteorin. Denna utveckling har exemplifierats i de båda Irakkrigen av den amerikanska armén. Men vad innebär manöverkrigföringens utveckling för underrättelseförbanden? Vilka krav ställer egentligen manövertänkande på inhämtningsförmågan?Syftet med denna uppsats är att undersöka och identifiera en del av de krav som manöverkrigföring ställer på underrättelseinhämtningen.  Detta för att kunna belysa om det finns ett utvecklingsbehov inom ramen för underrättelsebataljonen.Denna uppsats är en komparativ studie.
