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.

Smart seed : fördröjd groning hos raps : försök med frö-coating samt litteraturgenomgång om frögroning, coating och praktisk tillämpning i reläodling

Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

Anhörigvårdare - kommunens stöd till anhörigvårdare och deras behov av stöd och hjälpFamily caregivers - the municipality's support to family caregivers and their needs of help and support

The family and relatives caring for older people in Sweden lies on an old tradition. The responsibility to care for older family members has gone from family to the society. The aim of this study was to examine the needs of family caregivers and their experience of municipality support. This study includes only the family caregivers who have the main responsibility for the care of relatives and have support from the municipality. The caregivers were not allowed to work more than 50 percent in another job.

Möjliga alternativ för att ersätta direktverkande el i flerbostadshus

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

Värmesystemsutveckling

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

Deaktivering av metanisering katalysatorer

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Nedskrivningsprövning av goodwill: En studie av regler som någon hittat på för en tillgång som inte riktigt finns

Since January 1 2005 all companies listed on a regulated stock exchange within the EU are required to present their consolidated accounts in conformity with IFRS. Among many other consequences goodwill will no longer be amortized over its useful life but instead annually tested for impairments in accordance with IFRS 3. The aim of this paper is to scrutinize the impairment test of goodwill as outlined in IAS 36 and analyze its implications. We conclude that the impairment test will probably lead to the recognition of internally generated goodwill in the consolidated accounts. We also conclude that the impairment test on highly aggregated levels will probably hasten the pace of this recognition since internally generated goodwill is used to shield acquired goodwill from impairments.

Medeltida dryckesglas i Sverige : En fragmenterad historia

Medieval glasses have for long been a neglected object group in archeological research in Sweden. With that in mind I choose to write about those in my essay. The aim of this paper is to bring the medieval glasses into the archaeological research. I intend to show where you can find medieval glass in Sweden and what kind of glasses have been made. I will also discuss why the archeological research is so limited when it comes to the medieval drinking glasses.

Purpose: The purpose of this study is to investigate how three banks country funds are performing relative to each other in regard to risk and return. And to find out if there is any underlying factor that may have affected the stock exchange in the different countries.Methodology: The study is based on secondary data and will apply the quantitative method, based on a deductive approach. The sample consists of three major Swedish banks and from them we have selected three country funds. The calculation formulas that have been applied are: Sharpe ratio, standard deviation and Arithmetic Average.Conclusion: The Writers concluded that Sweden funds had the highest yield to lowest risk in both periods in all three major banks. We have also concluded that the underlying factors affecting a country fund.

Vattnets väg genom ett romerskt bad. - tekniken bakom marmorn.

This essay focuses on the technical systems and functions behind how a Roman bath operated. I will present a general view by going through each part of the waters path through the bath one by one. Since there is no such thing as a standardised Roman bath I will, under each headline, present the sub subject with a presentation of the workings and then exemplifying through archaeological findings and ancient literary sources.This essay is therefore meant to present a thorough and clear presentation of the technical aspects of a roman bath. The aim is to give the reader an understanding of how a bathhouse worked in general and why. To this I want to present problems that the Romans were faced with and how they solved them..

Val av överlastskydd för elektriska ventilmanöverdon på kärnkraftverket i Forsmark

At nuclear power plants, electrical valve actuators are important for ensuring that the reactor core is water covered and the pressure in the reactor tank and containment is limited. The electrical actuators are provided with overload protection in case of drawing higher current then the motors are rated for. When safety manoeuvres are needed, the overload protection must not trig and cause the valve to stop before completing the manoeuvre. Analyses have showed that the current settings of the overload protection may cause an illegitimate trig at the worst theoretically possible accident. A new method has been developed with conservative assumptions and applies overload protections for all electrical valve actuators at the three reactors in Forsmark..

Hunner eller heruler? : Skånes kontinentala kontakter under folkvandringstid

 The intention of this paper is to explore the contacts between the Swedish province of Scania and Southeastern Europe in the Migration Period. This has been done through comparative studies of four object categories. Parallels to glass, horse trappings, jewellery with inlays and sword decorations found in Scania have been studied in southeastern and centralEurope, as well as the cultures of peoples involved in the Migration processes. The conclusion is that contacts were upheld in several ways: through trade, exchange, alliances and gifts. Old trade routes along the Vistula were used in the south-easterly direction to the Pontic area but were changed to the Moravian Gatein the latter half of the period, while westerly routes probably worked most of the time.
