Finns det potential att införa en massdatabas för handel och utbyte av överskottsmassor i Eskilstuna?
In Eskilstuna and Sweden in general the level of reuse of surplus material containing soils and rocks from excavation is low. In this report the potential for increasing the reuse of excavated material in Eskilstuna by using a web-based earth information database has been examined. The purpose of a web-based earth information database is to connect those who have surplus material with those who need material for a fast and simple transaction. The intention is to give Eskilstuna a more environmentally and economically efficient handling of surplus material by increasing the level of reuse and thereby reducing the amount of surplus material that is wasted and emissions given off to the atmosphere during transportation. The potential has been examined in two different ways, by tracing information about a number of projects to see if excavated material driven to the dump could have been used in another project and by interviewing eight of the work leaders active in Eskilstuna.
Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines
With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

Framtidens Hus
The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

Finansiell psykologi : En empirisk studie av olika faktorers påverkan inom finansbranschen
Investors have been shown to be driven by emotional and psychological factors. This contradicts classical financial theories, for example the Efficient Market hypothesis which states that all investors act rationally. Behavioural Finance is an area of study which describes various psychological factors which may result in irrational investor behaviour.The primary question of the study is: which factors do operating people in the financial sector consider themselves to be influenced by? The purpose of this study is to investigate the factors which affect the process of creating forecasts or making financial decisions. The study examines in addition if there is a correlation between length of investor experience and overconfidence in forecasting accuracy and investment decision making.The study includes both quantitative and qualitative analysis.
Pragmatisk förmåga hos barn med cochleaimplantat
A cochlear implant (CI) is a hearing device that makes it possible for individuals who are deaf or has a severe hearing impairment to receive auditory information and develop spoken language. The pragmatic ability may be affected. In short, pragmatics may be described as the study of language use in social contexts. Pragmatic ability can be seen as the result of the individual?s behavior as well as the underlying causes.The aim of the present study was to describe the pragmatic ability in children with CI.
Nu är det mål igen : En studie om målsättning hos innebandyspelare i herrlandslaget
The purpose of the present investigation was to identify how knowledge about goal-setting is developed and applied in practice of male players in the Swedish national floorball team, by using a qualitative methodology. Participants were 6 players playing for the Swedish national team. They were asked to respond to the interview questions in relation to their perception of setting goals for a successful outcome in sports, how their goal- setting process has developed and how they deal with goal setbacks and goal attainment. Results revealed that Swedish national players in floorball employed goal setting often for both individual and team goals in practice and competition. In addition, many interesting findings regarding the process of goal setting emerged in the result.
Emotionellt värdeskapande : Känslans roll i företagets värdeskapande
Management research has during the last decades devoted itself to finding new solutions as to how companies in a better and more efficient way can take advantage of the human resources to create added value. This brings up the problem of understanding, making visible and identifying these resources and to be able to influence them. A section of the issue of understanding that has grown stronger lately builds on the role of emotions in transformation of resources. Research into this issue has shown a discrepancy where a common view seldom can be assumed. This leads to the first aim of the essay; to create a theoretical framework for understanding and dealing with the role that emotions play when it comes to creating added value in a company.
Genererar insiderhandel överavkastning? : En studie om insiderhandel på Stockholmsbörsen
Bakgrund: Börsen ger en möjlighet för företag att erhålla kapital och för placerare atttillgodogöra sig avkastning. Personer med insyn i det egna företaget, så kalladeinsiders, kan dock i egenskap av sin position inneha kurspåverkande information somövriga aktörer på marknaden inte har möjlighet att ta del av. Tidigare forskning harpåvisat att insiders utnyttjar denna informationsasymmetri för att på så sätt tillgodogörasig överavkastning.Syfte: Syftet med studien är att undersöka om insiders kan tillgodogöra sigöveravkastning genom handel med aktier på Nasdaq OMX. Vidare ämnar studienutröna eventuella skillnader i överavkastning beroende på företagsstorlek,transaktionsstorlek samt tidsperiod.Metod: I denna studie har en kvantitativ forskningsstrategi i form av en eventstudietillämpats. Studien har en deduktiv ansats och undersöker insidertransaktioner från 90företag på stockholmsbörsen under tidsperioden 2006-01-01 till 2011-12-31.
Är ökad pressfrihet dåliga nyheter för korruption? - En kvantitativ dataanalys som testar styrkan i sambandet mellan pressfrihet och korruption.
This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and therefore there is a lot more to be published on this issue.This paper looks at press freedom as one of the most important parts of a democratic society and that it plays a vital role in reducing corruption as both an informant on key issues and also as a ?watchdog? on society. But press freedom cannot be seen as an ?easy fix? in a country or the international community's struggle to reduce corruption.

Analys av hur byggnadens höjd påverkar energiförbrukningen i flerbostads- och kontorshus
This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.
Personalnedskärningar och aktiepriser : En eventstudie av sambandet mellan personalnedskärningar och aktiepriser under perioden 2008-2012
Purpose: The purpose of this thesis is to investigate whether abnormal stock returns could be identified as a result of a layoff announcement during weak economy.Method: An event study methodology.Theory: Efficient market hypothesis, signal theory.Empirical results: Quantitative data from observations of stock prices in thirty two companies listed on the Nasdaq OMX Stockholm, in the period 2008 -2012.Conclusion: The results indicate that the market reaction was negative because there were negative abnormal returns on the Stockholm Stock Exchange during the period 2008-2012 in connection with the layoff announcements. The market reaction was milder when staff reductions were carried out as a result of a restructuring and stronger when staff reductions were carried out as part of a cost reduction program.The layoff announcements elicited different market reactions depending on the company's industry affiliation. The most negative reaction was in the Healthcare industry. Negative abnormal returns were lower in industries Industrials, Consumer Services and Consumer Goods. There were no abnormal returns for shares of companies in the industry Financials.
Täckning av plansilo :
With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.
