This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.

This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

It has become more common for organization to operate a lot of projects at the same time. These projects affect each other, either in way of resources or technical. Projects in a multi-project environment depend and affect each other, and in most cases they rival about resources, decision-makings and priority. To lead a project portfolio with several projects is a major challenge. The most common problems that occur are vague objective, unclear working conditions, resource shortage and problems of priority.

Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.

The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.

Bachelor thesis, Controller, Program of Master of Science in Business and Economics, School of Business and Economics at Linneaus University in Växjö, Sweden, Course Code: 2FE13E:3, Spring 2012 Authors: Jacob Cedergren, Adam Pettersson, Hampus SkelterwijkSupervisor: Anders JerrelingTitle: The ERP-systems impact of the management control - a case study of VIDA AB Original Title: Affärssystemens påverkan på ekonomistyrningen - en fallstudie på VIDA ABBackground: New technology has given businesses new opportunities to use and store information and the current information systems has changed the way of working in more or less all sectors and operations. ERP-systems have been one of the most important IT innovations in the past decade. The potential of a properly implemented ERP-system is great because it has got the ability to link the company?s different areas together. Despite its many advantages, there are several examples of cases where the acquisition and implementation has been a total failure.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

Through the rulings RÅ 2010 ref. 11, HFD 2011 ref. 75 and HFD 2011 not 88 the Swedish Supreme Administrative Court have extended the concept of same or similar activities which can be found in section 57, clause 4 of the Swedish Income Tax Act. Through the ruling the Court has partly clarified the application area of the regulation but question marks still remains.In the statutory text there is no definition of what shall be regarded as same or similar activity and the preparatory work does not give any further direction on how the concept should be interpreted. Ever since the amendment in 1995 the general view has been that activities can be transferred between different companies without affecting the waiting period in the company of origin.

The aims of this project were to describe the circumstances around dogs being left alone in cars, to investigate owners? knowledge of the risks associated with leaving dogs in cars and the relevant legislation and, finally, to study how changes in the air temperature and air composition in the car affect the dog. The project consisted of a survey of the literature, a questionnaire part and an experimental part. An important conclusion is the importance of the level of knowledge of owners, since there are several ways in which an owner can prevent their dog from heat stroke and, in the case of an eventual accident, their action can have direct consequences in minimizing the long-term damage to the dog and even whether or not it survives. Fewer than half of the owners in the study knew that for a dog suffering heat stroke, the most important thing is to bring the body temperature down. Only a third of dog owners knew that if a dog is left in a warm car and showing signs of heat stress, then the police should be contacted and the dog quickly helped out of the car.

The purpose of this paper is to present and analyze the yearly expenses for Swedish rental apartments during the period 1999 to 2007. At the end, it will give the reader a general picture of how the cost-level has fluctuated depending on the production year when the apartment building was finished, and where the same building is located. This paper has the following questions as a starting point:- Can there be an identification of regions depending on where people tend to favor renting an apartment?- How are those regions distributed? That is, where are the cost-levels of the yearly rental expenses highest and where are the levels lowest?Nine statistical surveys from the Swedish government agency Statistics Sweden (Statistiska Centralbyrån) have been used as primary sources for this paper. These surveys deal with price pictures of housing in general, but for this paper the only information that has been used is the one about rental apartments.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.
