Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

The report also presents possible solutions to prevent the occurrence of defects. It also covers the issue of how the client looks at Peabs way to overcome the objections of warranty inspections. The report has the following issues:?What are the most common errors observed during the warranty inspection??What are the causes of complaints??What can be done to reduce the number of complaints??How the customer thinks that the complaints be addressed?Twenty-five Guarantee survey records from the projects Peab has done in recent years has been the starting point for the investigation.

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm. The project is in a village near us, where we should support a school, a churh, a home for the aged, a kindergarten and a parish hall with heat. In my work I have compared two different alternatives with each other. The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.

The purpose of this work was to see if it was possible to rebuild an old dairy house into a house fore sheep production. The goals fore the work was to see witch kind of production model was suitable, how the actual drawing would look like and witch kind of interior was needed. The building was built in the beginning of 1900. It is located on the mountain Kinnekulle in Sweden. It was a big production fore its time and hade about 60 dairy cows. It was a lot of hard work because the floor was built by big stone blocks and it was very hard to rebuild when some more automatic solutions came fore handling all the manure. The idea of remaking the building came when we rebuilt the roof fore 5 years ago.

This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.

ABSTRACTTitel: Bolånetakets påverkan på bostadsmarknaden ? Ur konsumenternas synvinkelNivå: C-uppsats i ämnet företagsekonomiFörfattare: Johan Sandberg och Joel ByströmHandledare: Aihie OsarenkhoeDatum: 2012 - 05Syfte: Syftet med detta arbete är att undersöka hur förväntningarna var inför införandet, ochhur konsumenterna påverkats av det nya bolånetaket som infördes 1 oktober 2010. När detnu gått 18 månader sedan införandet, hur har bostadsmarknaden påverkats urkonsumenternas synvinkel?Arbetets bidrag: Tidigare studier inom området (t.ex. Gauffin, 2011; Bekeris & Lagelius,2011; Claesson & Megaache, 2011) fokuserar på hur hur bostadsmarknaden i sin helhet harpåverkats av bolånetaket, med främsta inriktning på bostadsrätter i Stockholm.

A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

The company Bergteamet, Boliden, Sweden, is installing ventilation shafts of the Garpenberg mine. For such work a platform is needed which you can stand on and work from. The Shaft Reinforcement Team at Bergteamet performs the installation work and is the sponsor of the platform. The project described in this report is performed at the department MEC, Mining Equipment Construction, which has been given the task to design and construct the platform, customized for the current shaft. After this the platform is manufactured and inspected at the workshop at Bergteamet.The design work was carried out as follows:- After an initial meeting a requirement specification was worked out, describing the problem and previous experiences of platforms and requirements for the design and equipment.- A concept sketch was developed with consideration of surrounding factors.- A constructed 3D model was presented along with the choice of materials.

During the last couple of years leaf-edge-cuts, typical to Otiorhynchus wingless-weevils, have been discovered on ornamental shrubs, especially Syringa vulgaris lilac and Ligustrum vulgare privet. These plant species have not earlier been attacked by wingless-weevils and because of that, the aim of this study is to see if new species of weevils have been established in Sweden or if the domestic weevils have changed their food preferences. This work also includes a literature study of known weevil species in Sweden and their host plants, and of wingless-weevil species in Europe that could be invasive here. Locations, where damage to previously named plants has been reported, have been examined. The extension and appearances of the damages have been documented in order to study if different weevil species make different types of edge-cuts.

The preschool constitutes a big part of many children's everyday existence. Its contents are therefore of great importance and the environment deserves a well thoughtout design. In this study, surveys in field and literature have resulted in conclusions around how plants can be used in children's play environments, in order to contribute to the experiencerelated values. The aim is to present conclusions to lean on when drawing up designproposals for new playgrounds, especially where the natural conditions are not so favorable. The first question that is responded to is how plants can be used in order to enrich the children's play environments.

In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.
