Styrelsens unika kompetensbehov : En studie av kompetensförändringen i styrelsen
Background: The board of directors is a key player in corporate governance. Their role is to ensure that the corporations are run with the interest of the shareholders as the main focus. In the beginning of the 21st century, a survey was made about the confidence of the Swedish business community and in which criticism was directed to the board of directors. The boards were deemed inadequate in their function and were often solely composed by members with similar experiences and competence, therefore lacking in diversity. In order to improve the competence and work of the board of directors, the Swedish code of corporate governance was introduced and its recommendations comprehend the boards? size and composition.
Valfrihetens konsekvenser : medvetna och omedvetna skolval
This study illuminates chosen parts of the present opportunities, in the Western World, for parents and children to choose which school the child will attend (freedom of choice), along with possible consequences that may follow. My research questions are: 1) Do tendencies show that freedom of choice leads to increased segregation, and if that is the case, how is it manifested and does it matter? 2) What relations between the student composition of schools and teachers' expectations and attitudes toward students are there? 3) Do the results from previous studies match with the result from my interviews? The methods used for answering the questions are literature studies and interviews made with six teachers who are working in two upper secondary schools in the northern part of Sweden, i.e. three from each school.The result shows that freedom of choice, regarding schools, seems to lead to student compositions that contribute to increased segregation in societies. It leads to more homogenous student compositions, in the form of ethnicity and social class, in schools in general, with consequences like different expectations and attitudes among teachers depending on the status of the composition.
Fermenterat blötfoder till gris
The purpose of this literature study was to examine what kind of composition fermented liquidfeed can have, what a desired composition is and possible advantages and disadvantages onhealth and growth performance of the pig. A well fermented liquid feed is characterized by a lowpH (.
Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala
There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..
Politiskt utanförskap : en studie av invandrarsammansättning, kommunorganisation och kommunpolitikers demokratisyn som förklaringsfaktorer av underrepresentation av invandrare.
The development that the Swedish society has experienced during the last four decades and the higher part of the population coming from foreign countries calls for a more intensive research on the situation of these groups. The purpose of this study is to find explanations of the differences in the share of immigrant politicians in Linköping and Norrköping. The starting point of the study is a model of factors assumed to affect the representation of immigrants in the municipality assemblies. The immigrant composition, the municipality organization and the view of democracy of the politicians, are all assumed to affect the civic participation. The civic participation is then assumed to affect the representation of immigrants in the municipality.
Lövsuccessioner i sluttningar längs nedre Umeälven :
Secondary deciduous forests, which have their origin in earlier pasture- and meadow-land in slopes along the lower reaches of the Ume river, are thought to contain high nature conservation values, in spite of a relatively low age. The aim of this study was to clarify how factors as historical use, exposition, disturbance dynamics and successional age influences the conservation values in these types of riparian forests and how this can be implicated in the practical work with conservation and management at Umeå municipality. Sample plots were placed in seven stands with a variation of their historical use, exposition, disturbance dynamics and age of succession. Conservation values as structure, tree-regeneration, abundance and composition of vascular plants, amount of dead wood and the abundance of signal-species were measured and registered. The species composition and especially the composition of tree species, differed between forests with different exposition and different historical use.
Georg Stubendorff, organist i S:t Jakob : En musiker i stormaktstidens Stockholm och hans concerto "O Jesu dulcissime"
AbstractJan Johansson: Georg Stubendorff, organist i S:t Jakob ? En musiker i stormaktstidens Stockholm och hans concerto "O Jesu dulcissime", [Georg Stubendorff, Organ Player in S:t Jacob's Church ? A Musician in Seventeenth Century Stockholm and his Concerto O Jesu dulcissime], Uppsala universitet, Institutionen för musikvetenskap, uppsats för 60 p, 2006.Georg Stubendorff, organ player in S:t Jakob's church in Stockholm 1663-1672, was one of the very competent foreign musicians that came to work in Sweden in the 17th century. The purpose of this essay is to contribute to the knowledge about him and about the conditions in general for church musicians in Stockholm during that era, and to present an edition of his Concerto a 3. It is shown that Stubendorff may have come to Stockholm from Livland, rather than Germany as earlier accepted. The Concerto a 3 is the only composition by Stubendorff that has survived (now in the Düben collection at Uppsala university library).

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål
This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.
Demografisk sammansättning samt beteende hos medlemmar i panel
The use of marketing research panels are a more and more frequently used source of information for studies within many different branches. The purpose of this report is to investigate the demographic composition of panels and compare it with the population of Sweden, a possible change in behaviour of respondents, and if the source of recruitment is the cause of possible differences in study results. The study was commissioned by Norstats Linkoping office. Sources for the data material include Norstat?s recruitment process and their two main panels with different recruitment sources.
Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker
One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.
Methane production from dairy cows : relations between enteric production and production from faeces and urine
Methane (CH4) is a greenhouse gas (GHG) that contributes to the global warming. One of the largest sources of methane is livestock, preferably ruminants which alone counted for 30% of the total agricultural anthropogenic methane emissions in the year of 2000. The reason to why ruminants are such large contributors of methane are that the gas is produced in the rumen by enteric formation and leaves the animals by belching, exhaling or by the excreta.Diets high in concentrates can result in a lower emission of methane. Also diets with a high content of starch, such as alfalfa-grass, have a methane-decreasing. It is profitable to reduce enteric methane formation since that form of methane is unavoidably lost.
Potatisens specifika vikt och kokegenskaper med hänsyn till odlingsplats och sort :
The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties.
This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Två år efter restaurering:Vad har förändrats i bottenfaunan?
The aim of the study was to examine if the benthos in a restored portion of a small lowland stream south of Linkoping differed from two non restored reference areas two years after restoration. The reference areas were one stretch downstream and one upstream stretches of the restored stream. The benthic invertebrates were collected using standardized kick sampling. In order to classify the communities and estimate any differences, three different indices were exercised. In addition rank-abundance curves and checklists were used to get a picture of species composition.
