When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils. The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.

This thesis describes how the development of a mechanical enclosure to an alarmsystem proceeded. The project was made on behalf of Inferno Light Indusec AB.The goal set to this housing would offer a home alarm in which Indusec?s uniquesound system would give the customer a new alternative on the market. They wantedto, among other things, create an aesthetically but at the same time affordable alarm.The aesthetic theme is something that is missing in today?s market.

The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.

The competition for Norway spruce pulp wood in Central Sweden increases, forcing the supply-structure of Holmen to face two important challenges. Firstly, it is of the outmost strategically importance to secure the long-term supply of Norway spruce pulp wood to the industries. Secondly, Holmen desires to increase the obtainable volume of Norway spruce pulp wood. This would enable the company to choose volumes in the lower price-segments and thereby decrease the dependency of costly marginal volumes. As this work shows, one part in managing these challenges could be to lower the quality standards concerning root rot (Heterobasidium annosum). Facts presented in the work shows that: 1. Technically, the TMP-industry of Braviken can handle a much more rotted pulp wood than that used today, although the cost of refinement increases.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

The Swedish National Rail Administration has changed in the past decade, from its origin after a less dramatic separation from the Swedish State Railways to becoming an authority with its own identity. Today the National Rail Administration is a large organisation with several different departments, each with its own unique function. To operate train services the railway needs to be ?in shape?, leading to a need for maintenance, reinvestments and new investments. For this purpose, the National Rail Administration carries out public procurement where contractors, who are able to perform maintenance and new construction, submit tenders.

During the 1970?s the interest for quality management and the concept of quality costs increased considerably. Business leaders noticed that there was a great potential for reducing costs of poor quality. Since up to 10-30% of a company?s total turnover may consist of poor quality costs some consider them as an unexploited goldmine.

The purpose of this study was to examine how the foster parent's need of support is provided. The study was built upon a qualitative method with interviews with ten foster parents. More specifically, its aim was too find out how the foster parents themselves looked upon how their need of support, and from whom the support was provided. According to the law, it is the social services obligation to provide the foster parents with all the support they could need. The picture the media sends out is different from what it should be because according to them, the social services fall short in the follow-up and also the support of the contact with the foster parents.
