Ersättning av fossilt bränsle i värmeproduktion: Pulverbrännare till befintliga oljepannor
Vi står inför en förändring, att minska vårt beroende av fossil energi till förmån för en ökad användning av förnybar energi. Incitament i form av ökade punktskatter på fossilt bränsle påskyndar omställningen för företag till förnybar energi och- eller energieffektivisering av sin produktion. Konsekvensen blir en successivt fördyrad kostnad för produktion av fjärrvärme med eldningsolja till tillverkningsindustrin. Punktskatt på eldningsolja stiger med 41 procent, från 2010 till 2015 för företagen. Att konvertera befintliga oljepannor med träpulverbrännare är en lösning för att hålla produktionskostnaden nere och behålla sin konkurrenskraft.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
Regionbiblioteken i Tanzania en fältstudie av den offentliga biblioteksservicen
This masters thesis concerns the Public Library Service in Eastern Africa, Tanzania. Our subject was developed through a feasibility study that gave us comprehension that developing countries have individual problems concerning books and libraries. We understood that the main problems were the libraries financial situation and their dependence on aid. We also understood that the libraries do not have the resources to satisfy the society as a whole. The major questions raised in this study are: - How do the regional librarians describe their work situation? -Which role do the Regional Librarians have in society? Data was collected through interviews and observation, and the study is a qualitative case study.
KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

BTJ övertygar: En retorisk analys av lektörsomdömen om barnlitteratur
The aim of this Master?s thesis is to examine how opinions and values are expressed in BTJ?s reviews of children?s literature. According to debates reviewed and interviewed librarians, many consider BTJ to be too directing when it comes to the libraries? purchases of books. Therefore I find it important to study how the reviews are written.
AI i verksamheter: Ett effektiviserings- och riskhanteringsperspektiv. En studie om till?mpningen av AI i organisationer
The purpose of this work was to investigate and provide understanding regarding how AI can be used to make organizations more efficient, where risk management is also discussed. The basic model for the study is the Resource-based view, which is about making use of one's
resources which are described through many different perspectives. The method used for this study was a qualitative analysis, which was applied through interviews with several people with high positions within companies and relevant skills, based on insight and experiential
knowledge.These people work in different industries, therefore a large part of the work was intended to carry out a comparative analysis between a line of different businesses. The results showed that AI is in a developing phase, and based on the respective industry, it has
developed in different ways. Finally, it turned out that AI can make businesses more efficient by, among other things, managing data and automating various work processes faster compared to humans.
Framgång i det kreativa företaget
From a management point of view, enabling organizational creativity is often referred to as reducing immediate control, increasing autonomy and enhancing the access to slack resources. At the same time, the business environment of today is fiercer than it was only a decade ago, and this renders a quest for more efficient approaches to competitively run a business. This paper aims to examine creative industries and more specifically try to identify a set of elements that are common for successful companies. As this industry has not been subject to any considerable array of studies, this thesis seeks to establish a structure for how to take both organizational models and leadership theories into account when developing an understanding for the process, organization and leadership of the creative business. By studying six separate creative companies, our findings suggest that conventional theories on organizational creativity do not adequately account for all factors that contribute to these companies' creative success.
Störningar inom kontrollzon
This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.
Familjehemsplacering hos "annan närstående" : en undersökning, med utgångspunkt i SoL 6:5, om socialsekreterares uppfattning och övervägande av närståendeplacering
Our study has its starting point in the Swedish social legislation (Socialtjänstlagen) and more specifically in the 6th chapter's 5th paragraph. That paragraph regulates that social workers should try to find a kinship care placement when they are about to do a placement of a child. Our purpose is to examine how social workers, before they do a placement of a child, understand the informal kinship that is not relatives, if they consider the informal kinship and if certain circumstances have an impact on the consideration. To get this information we have done five interviews with social workers. Recent studies show that social workers in past years have begun to think more positively of people's kinships and that they more often use the resources of the kinship.
Skogens produktionsvärden och dess betydelse för Sveriges ekonomi
The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.
SATSA FRISKT FOR LIFE : En komparativ studie om kundens köpbeteende inom träningsbranschen
Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.
Balis trädgårdar
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige
The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).
