Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Likviditetsgaranti ur ett företagsperspektiv

The aim of this paper is to investigate the underlying motifs leading to the decision to appoint a supplemental liquidity provider and how they vary between companies. As the first study of its kind to take on an internal company perspective, the goal was to broaden the knowledge base of the field and lay ground for further studies. The study has been conducted by interviewing companies providing the service, their customers and the stock exchanges which they are traded on. The results show that there are two main motifs for appointing a liquidity provider, 1) Creating conditions for increased trade and 2) Improving the pricing of the stock. There was also a supplemental group 3) Other motifs consisting of the observations that would not fit in any of the main categories.

Centrala Begrepp som Länken Mellan Ämnen : En undersökning av de centrala geografiska begreppens interdisciplinaritet

 Language is an important indicator of the interdisciplinarity of a certain subject. Therefore this study evaluates the use of central geographical words and concepts, by teachers and students, in seven communal, non-optional subjects in a Swedish upper secondary school. This study provides results after observations of seven subjects on seven occasions, at one upper secondary school. This study shows that by a method of observation, central geographical concepts were used by teachers and students at various extents. Furthermore, the observations provide results of the concept use by over 100 students and 12 teachers.

Scoutförskola : En förskola med scoutprofil

Due to the interest of starting a preschool with a scout profile in my circle of acquaintances I chose to write my report about how the scout method would work in a preschool. I did this by comparing the origin of scouting and preschool. I based my report on the following questions:Are there any similarities or differences with curriculum, education act and the scout method that can make it easier/harder to work with the scout method in the preschool?There are many theorists that have had influence on the preschool. Give some examples of their theories that could affect the scout preschool?What is the difference between a teacher and a scout leader?What would a preschool look like if you included the scout method in the daily activity?With the help of my literature studies I compared the scout method against the laws and rules to make sure that the scout method doesn?t contradict them.

Punktlasttestning av olika bergartstyper i Kiirunavaaras liggvägg

Examensarbetet ingår i den slutliga delen av kandidatutbildningen i naturresursteknik och utgör 15 högskolepoäng. Utbildningen är inriktad mot geologi och det avslutande arbetet ska ha anknytning till ämnet. Under våren 2012 presenterade representanter för LKAB förslaget att basera examensarbetet på att dokumentera hållfastheten hos bergarter från Kiirunavaaras liggvägg med hjälp av punktlasttestning. Tidigare undersökningar av hållfastheten hos bergarterna i Kiirunavaara har främst gjorts genom enaxiella tryckhållfasthetsmätningar. Det finns ett behov av att undersöka hållfastheten hos bergarterna i Kiirunavaara då gruvbrytningen sker djupare ned i jordskorpan och kraven på säkerheten ständigt ökar.

Motiverad för riskmedvetenhet? En studie om stadsarkitekterna i Dalarnas läns medvetenhet om, motivation för och arbete med risker vid fysisk planering.

The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.

Jämförelse mellan viltbehandlade och obehandlade granplantor : Med inriktning på höjdtillväxt och betesfrekvens

The report is a comparative study between spruce plantations where 4 plants are treated with deer repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-repellents.  The report indicates that wildlife-repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years.  Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing..

Kronunionens återkomst : En empirisk underso?kning av konjunkturscykler, arbetskraftsro?rlighet och handelsintegration fo?r att avgo?ra mo?jligheten att info?ra en gemensam valuta i Norden

This paper is an assessment of whether the Nordic countries constitute an optimum currency area (OCA) or not. Hodrick Prescott-­?filtered data of real Gross Domestic Product (GDP) and rate of employment are used to investigate the similarity of business cycles between the target countries through a series of correlation analysis with Sweden as the base reference country and also by using a linear regression model. Additionally there is an evaluation of trade volume and labour mobility between the countries. Our results indicate that Iceland had the least similar business cycles within the Nordic countries and that the area should therefore possibly comprise Denmark, Finland, Norway and Sweden. .

Kundrelationer inom banksektorn : Hur svenska storbanker verkar för att säkerställa kontinuitet och lönsamhet inom studentsegmentet

The purpose of this study is to investigate how the major swedish banks look upon and promote student profitability as well as long-term relationships within the student segment from a CRM point of view. The study incorporates a qualitative course of action with an abductive research approach which has been carried out by conducting personal and telephone interviews with representatives from three out of the four major swedish banks Nordea, Swedbank and Handelsbanken. Our research finds that the banks appear to regard their relationships with students as long-term investments, but that they simultaneously seem to lack distinctive, clear and procreative strategies for securing these relationships. Furthermore, the development of profitability within the student segment is considered an informal process that does not necessarily need to be computed through the use of quantitative estimates. Also, educational variables does not influence the banks as they segment their customer base and the student-centred offerings within the banking industry is to be deemed as being standardized rather than differentiated..

Diagnostiksystem i gaffeltruckar

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

Interaktion mellan banker och kunder via bankernas Internettjänster

The purpose of this essay is to analyse how and why culture and tradition is created and maintained within a minor student society at a Swedish university by looking at its history. The West Coast Nation student society provided the material which was subsequently analysed and three sociological perspectives were applied in order to give the study a theoretical base. In order to investigate the purpose of the society, durkheimian theories on functionalism were applied. Moreover, Bourdieu?s thoughts on social fields were used as well as Elias? theories on the established and the outsiders.

Studie om pedagogers syn på lekens betydelse i undervisningen för den sociala utvecklingen av barn med autism

The aim of this study is to examine educationalists experiences of play as an educational toolin the work to promote the social development in children with autism.The relevant issue, for this study, is: In what way does an educationalist work with play withchildren with autism? What are the results of using play in the educational work? What arethe possibilities and what are the obstacles in using play in educational work?This study has been carried out as a study of literature in the field and qualitative interviewswith five educationalists that are working in a mid Swedish county.The result of the study shows that educationalists have a positive view of using play in theirwork and are using play in varying ways in their everyday work. Using play as a method intheir work always happens according to the ability and condition of the child. They (theeducationalists) think that play has great opportunity and advance as a method and gives thechildren joy, increase their sense of ability, the base for the social participation in play, andthe development of social skills.There is a certain hesitation among educationalists when it comes to using play as a methodfor children with autism , but the most of the educationalists consider play as promoting thesocial development although the development always will happen at the pace(rate)of thechild..

Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.
