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.

The most vital for a business is to understand how to please and satisfy its customers in order to make them loyal to the company. Companies weapon for competition in the retail business is defined through the retail mix. The retailer however often have limited resources whereas they have to prioritize between the factors included in the retail mix. The main purpose for this paper is to investigate what kind of internal connections that may occur between the factors in the retail mix, with focus on the job satisfaction as a catalyst on driving the values of the parameters included in the retail mix, where the factor service is the starting shot for the others included..

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

Organic layers and broilers will according to (EEG) no 2092/91 be fed 100 % organic feeds in year 2012, which is expected to present problems associated with the specific protein requirements of poultry. This document aims at describing the feedstuffs that possibly may constitute a part of the solution to these problems. Peas, field beans, naked oats, canola, hempseed and sunflower come out as interesting feedstuffs. Biproducts from the milling and dairy industry together with marine protein supplements may be brought to the fore, provided that the demand for organic products will rise further..

In the research a qualitative method has been used to do interviews with six supervisors and to do analysis of material. By the help of literature studies, I explained leadership. Result of the study indicate that leadership concerned supervisor should prepared to do the right thing in every situation and to find best solution of different situation that come up on the work. The way to do all this is important to create leadership.

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Pica is a behavior that can be seen in several animal groups. In cats, it means that they are eating, chewing or licking on material that is non-food. In this study the data was collected through an online survey. In total 522 responses, of which 26% of the cats were exhibiting pica. It was found that 28% of the housecats and 26% of purebred cats exhibited pica.

Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.

Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Banks are an important institution for the economy of a society. During the later years the world of banking has changed. Several new actors have entered the market and taken over traditional bankservices as well as new ones. The way of conducting banking has changed with the event of new technology. One of the banks customer segments, the students have also been under a change. With a changed market companies have to adapt to the new rules of the game.

This thesis is a case study with a qualitative approach. The company examined is The Astonishing Tribe (TAT) making user interfaces for mobile phones. The company has had a growth of 1453% from 2002 until 2006. We have examined what are the key factors for keeping innovation while growing. The most significant factor not supporting innovation within the case company is the will to take calculated risks.

This paper tests the information signalling hypothesis on a sample of firms making open market stock repurchases. Using an earnings-based valuation model, we find that a majority of repurchasing firms are undervalued relative to their economic value. This result is consistent with previous academic studies, which claim that undervaluation is the prevalent factor explaining the observed abnormal return following the announcement of a repurchase program. We do not, however, find any evidence that the repurchase is consciously made by management to provide the market with new information. .

pcSKOG-gård is a computerised manager plan for private forest owners, developed by the pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and GIS-applications. The purpose is to offer a program for private forest owners managing the forest and with the possibility of updating the actual status of the forest. The company pcSKOG AB is the leading producer of programs for forest management and has developed the program since 1997. The program is currently the most common program used by private forest owners in Sweden. The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations. The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services. The study material has been collected during two phases.
