This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

ABSTRACT Objective: The objective of this review was to describe the effects of low carbohydrate diets in people with diabetes type 2. Methods: Review. An article search was made in the databases PubMed and Medline. The search resulted in 17 studies. After review and analysis of the studies main results five categories were highlighted; bloodsugar levels, HbA1c, weight, lipid levels and antidiabetic medications.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

This thesis studies the way valuation of investment properties is conducted in accordance with IAS 40 and how reliable these valuations are. This has been conducted by studying ten Swedish real estate companies listed on the NASDAQ OMX, during the period 2005-2008. The study shows that all companies use valuation models to determine the fair value of investment properties. Two different types of models have been identified. Companies that use the cash flow model show inconsistencies in time horizon, and how they determine the horizon value.

This is a work that look at the factors that affect future monthly costs when buying a house in Sweden and which options are the most financially favorable over a 30 year period. The work also examines whether it is economically beneficial to invest in a low-energy house regardless of geographic location in Sweden, and discuss about whether a calculation template can help individuals to choose more environmentally friendly options. The work has been limited so that a certain number of predetermined factors and its measurable values have been developed with the help of a literature study. The factors chosen are building type, climate, heating systems, loan interest rates, energy prices, energy price increases, inflation rates and down payment. These are then combined into 72 different calculation cases which get put in a calculation model made in excel.

Over the past few years the Swedish forestry industry has become increasing interested in direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method. This study evaluated experiments that focused on direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

Declining union memberships are a fact in both Sweden and Finland. At the same time, the autonomous labour market parties and the high membership rates are the most significant factors for the two countries compared to Europe and the rest of the world. These two factors have in turn been developed and strengthened since the beginning of the twentieth century. By autonomous labour market parties I refer to the fact that the labour market parties themselves through collective bargaining are agreeing on the labour market conditions, without interference from the government.This paper is therefore taking it's stance in the question of what happens with the autonomous labour market parties when the membership rates are in decline. With this in mind, this paper describes the judicial development, the collective agreement and labour market structures, the legal consequences of collective agreements and the opportunities of industrial and sympathy action in both Sweden and Finland. The two countries' systems of labour law have caught some negative attention, hence two of the most discussed cases of recent years are given some attention as well. The collective judicial conditions are very similar in both Sweden and Finland regarding the labour market main actors' collaboration, the collective agreement structures and legal consequences and the opportunities of industrial and sympathy action.

Many enterprises have shortcomings in the transfer of information between different departments. Furthermore, routines for maintaining knowledge in order to be able to use this experience in the future are often lacking. Time and resources spent on improving these systems and procedures can provide significant benefits in terms of saved time and reduced costs in the later stages of a project. The benefit of this is not only a greater clarity and a reduced risk of misunderstandings, but also the preservation of knowledge that would otherwise be lost.The aim of this study has been to examine the process of information transfer and the transfer of knowledge between the calculus department and production manager in projects at Erlandsson Bygg i Öst AB. An additional aim was suggestions for improvements in the calculation handover and at the end of a project, where it was possible.The study was primarily conducted through literature studies and interviews.

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

The main purpose of this Master Thesis has been to evaluate whether active fund management is profitable on Emerging Markets. The material used to examine this consists of 106 actively managed funds, with varying length during the period 1988-2006 and who uses MSCI Emerging Markets (MSCI EM) as benchmark index. The thesis has been written under the supervision of the Asset Management Department of Länsförsäkringar AB (LFAB) and the Department of Production Economics, Linköping Institute of Technology. Apart from the main purpose, the methodology used is also meant to form a template for in-depth or similar studies, preferably by the assigner of this survey, LFAB.The results shows that the median manager underperforms the MSCI EM throughout the whole period, which leads to the conclusion is that active management on Emerging Markets is not profitable. A grouping of the funds based on tracking error still shows that a majority of the managers in all of the groups underperforms against the benchmark.
