The freshwater pearl mussel Margaritifera margaritifera is an endangered species. To survive, the young mussels demand a fairly coarse bottom material containing an appropriate quantity of organic substrate to survive without suffocating. In order to estimate if a bottom is suitable for juvenile mussels, samples of the sediment are needed. To obtain samples a sampling device called the Mulv collector has been developed within this project. Bottom samples were collected from 18 stations in 4 south Swedish streams, Vramsån, Kling-storpsbäcken, Brönnestadsån and Bräkneån.

Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

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.

Introduction: Pregnancy, obesity, aging and certain diseases are examples of conditions thataffect the body, its constitution and composition. Simpler methods to estimate bodycomposition are needed to complement more advanced traditional methods to better identifythe health status without sacrificing accuracy and precision.Objective: To validate the results of body composition from bioelectrical impedancespectroscopy (BIS) against results from the study reference method, dual energy X-rayabsorption (DXA), in overweight and obese lactating women after childbirth.Method: The design of the LEVA-study (Lifestyle for Effective Weight loss during lactation)consisted both intervention and longitudinal follow-up, which gave the opportunity tovalidate the absolute values (accuracy) and the ability to detect changes (precision). Themean difference between methods was tested statistically by paired t-test. Bland-Altman plotsused to examine the degree of agreement between BIS and DXA, but also distribution andany systematic differences. Association between methods was measured by using Pearson´scorrelation coefficient.Results: Between BIS and DXA, absolute measurements of the variables fat-free mass (FFM)and fat mass (FM) showed a statistically significant difference (p < 0.001).

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.

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.

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.

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.

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

In order for construction projects to be completed within the specified time limit while at the same time be financially sustainable it requires thorough preparation and an extensive planning. Most essential is the groundwork and the design that determines the project's progress. There are many aspects to consider in order to avoid inconveniences such as delay, litigation, unexpected cost etcetera. If mistakes are made in an early stage it is very likely that the error will follow the process and become an expensive correction cost towards the later part of the project. In other words, it is expensive to rectify defects later on.

Title: Besparingar inom Barn- och utbildningsnämnden.Seminar date: 29th of May 2009Course: Degree thesis in Business Administration, bachelor thesisAuthors: Amela Smajlovic and Sten SundfeltAdvisor: Leif HolmbergPurpose: Our purpose is to explain the cost-saving process that many municipality organisations face because of the global financial crisis.Limitations: We have limited our study to the municipality of Landskrona and Kristianstad.Method: Our study has a qualitative approach. By using open interviews we have been able to get an open dialog with our respondents.Theory: We have compared with different theories, such as Rombach?s budget-theory and Wildavsky?s role theory.Empirics: The material is based on interviews and conversations with key figures in different levels of the organisations in Landskrona and Kristianstad.Conclusions: The success of a cost-saving process depends on the engagement, awareness and how inclined to changes the persons in the organisations are. Has everybody the willingness to take responsibility fore the organisation and the changes that the surrounding world claims?.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

This study concerns how organizations manage various problematic areaswhen implementeing Business Intelligence and experiences from BusinessIntelligence project failures on management level. In order to highlightthese questions, we have carried out interviews with four organizationswhich have great experience in working with Business Intelligence on adaily basis.The result of the study shows that all organizations deal with difficultiesregarding cost-benefit issues and justification concerning BusinessIntelligence investments. The result also showed that the organizationsfaced difficulties with integration concerning time and cost. Documentingand securing support systems presented different attitudes between theorganizations, primary in the question about sub complements to BusinessIntelligence and in the way that they were documented. In the discourse oflegal issues and privacy the majority of the organizations chose not to storepersonal information relative to legal security demands.
