Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Sectra Mameas is a medical technology company in an expansive phase that is planning to increase its volume capacity with 50 % in the beginning of 2009. This to be able to deliver the increased number of systems that the customers request. To be able to produce more units the takt time of the assembly line needs to be shortened. This could only be done by identifying and solving recurring problems. To be able to find the problems, create a common knowledge of which these are and eliminate them the production department of Sectra Mamea needs to visualize certainKey Performance Indicators (KPI) in the organization.

Theory of mind är att kunna tillskriva andra människor mentala tillstånd som förklarar deras beteenden. Dessa mentala tillstånd kan röra sig om uppfattningar, intentioner eller känslor.    Theory of Mind Scale är en bedömningsskala utformad av Wellman och Liu (2004), som undersöker olika nivåer av theory of mind. Theory of Mind Scale är uppbyggd i skalsteg med stigande svårighetsgrad. Syftet med föreliggande studie var att översätta Theory of Mind Scale från engelska till svenska samt validera bedömningsskalan för barn mellan 3 och 4 år. Studien syftade även till att se om det fanns ett samband mellan dessa barns förmåga till theory of mind, impressiva grammatiska förmåga och impressiva ordförråd.      Valideringen i föreliggande studie visade att skalstegen i den amerikanska originalversionen av Theory of Mind Scale var applicerbara på barnen i föreliggande studie, med undantag för den sista uppgiften.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

This master of science thesis intends to examine how the established innovation theoriesinteracts with the social and cultural phenomena arising from the reduction in communicationcosts as a result of the development of the internet.The aim is to present a knowledge inventory of attitudes to and experiences of an openapproach, with emphasis on collaborative innovation, in product and service developmentdriven companies in different fields. The studied theories and the empirical results forms thebasis for an analysis of how companies can benefit from the diversified knowledge that existsoutside their borders as well as an exploration of the potential for this kind of knowledgeexchange to act as a catalyst for innovation.The theoretical part of the study is based essentially on two tracks: (1) innovation theories witha focus onopen innovation and user innovation, and (2) a broad review of how theories ofdiversified knowledgeand collective intelligence has become possible to apply in an innovationcontext. The empirical part of the study is based on material obtained from semi-structuredinterviews with respondents from six companies.The results show that companies have implemented unstructured innovation initiatives withoutany formal links to the structured product development processes, which are part of thecompanies core activities. The main conclusions include the following insights: There is a needfor structured links between the unstructured initiatives and the core activities, which makes itpossible to take promising ideas to market. The companies also have to lose some control of theunstructured initiatives; consequently it is impossible to pinpoint what the outcome will be.

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

The aim of this thesis is to create an understanding about how and to what extent a Swedish expatriate manager needs to adapt his/her leadership in accordance with the culture of the host country. Thus shall different managers? perceptions of experienced management overseas be studied. To accomplish our aim, three different problems have been designed. These are as follows: In what way does the manager?s earlier experiences and knowledge about expatriation affect her or his leadership in a new cross-cultural context? How does the culture of the host country affect the expatriate manager?s leadership? How does the expatriate manager handle contradictory demands: that is differences in expectations from subordinates and the higher management? We have chosen to use an abductive approach in order to do a qualitative study and we have therefore conducted eight case studies to create a foundation for distinguishing patterns.The case studies are based on eight Swedish managers with experience from expatriation. The theoretical framework is structured upon three main themes including; knowledge and skills a global leader needs to possess, the relation between the leader and subordinates, and contradictory demands.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Samhällsstörningar i form av större olyckor, naturkatastrofer och liknande kriser har under senare år varit relativt frekvent förekommande i Västsverige. Denna kvalitativa studies övergripande syfte var därför att fördjupa kunskapen om vissa avgränsande faktorer som upplevdes som underlättande respektive försvårande med avseende på ledarskapet vid hanteringen av orkanen Gudrun samt vid raset av Europaväg 6 i Munkedals kommun. Ett delsyfte med studien var även att koppla studiens resultat mot Ronthys (2006) teori om ledarintelligens. Underlaget för studien utgjordes främst av hur personer i ledande ställning inom räddningsorganisationen upplevt dessa händelser, något som författaren fick ta del av genom sju semistrukturerade intervjuer. Av de intervjuade var sex män och en kvinna, åldersfördelningen varierade mellan 40 till 65 år.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.
