Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

Background and problem: Higher and other demands are made on management control systems in organizations which have a superior non-financial objective. Systembolaget, a state-owned company with monopoly to sell alcoholic beverages in Sweden, combines two main objectives which can be considered as conflicting, one financial target and one superior non-financial public welfare target. The research questions are focused on the translation of information through the organization?s levels and if the management control system makes it possible to run the organization according to both of the two main conflicting objectives.Purpose and Delimitations: To describe, analyze and evaluate how management control can be used in an organization, which is not profit maximizing and has both non-financial and financial objectives. The essay does not try to describe or draw generalized conclusions regarding general perspectives on Systembolaget?s assignment and objectives.Method: A qualitative and evaluative case study based on interviews with five employees at different levels in Systembolaget has been carried through.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

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.

The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.

Hepatitis E virus, HEV, is a frequent causative agent behind, especially waterborne, infections in developing countries such as India. However, during the last years the number of non-travel-associated infections in industrialised countries, for example US, Germany and Sweden, has increased. The symptoms vary from mild with nausea to icterus and it can even be lethal. There are four different genotypes of HEV and many studies consider HEV infection to be a zoonosis. Scientists have by using phylogenetic analyses found great genetic similarity between strains isolated from humans, pigs and food, such as pork and liver, especially among viruses belonging to genotype 3.

The object of the thesis is to propose a new lighting plan for the square Fyristorg in Uppsala, and to describe the process which have led to it. It all started when I choosed the place together with the municipality of Uppsala. I have been doing research and analyzed how the place and it´s existing lighting works both during different times of the day and also in the evening. After researching the place and it´s existing lighting I´ve decided to put up the following goals fot the new lighting design. 1. The general light level of the place shall be experienced as higher than today. 2. The light level of the place shall be adapted to the light levels of surrounding places. 3. The lighting shall be free from glare. 4. The lighting shall be adapted to people passing by. 5.The lighting shall be adapted to the surrounding architecture. 6.

Today?s community requires an increase in food production. Animals are today bred so that they produce more than their ancestors did. Production has been the most important and breeds with the highest production levels have therefore become popular. Many of the old local breeds have become extinct or are about to become extinct because of this trend.

Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.

This paper has bearing on the subject of foreign policy analysis and decision-making,but is nonetheless important to peace and conflict studies due to its emphasis onnuclear weapons and deterrence.I have constructed a theoretical framework for the analysis of foreign policydecision-making that I set out to test on a crucial case. The framework iscrosscutting, and takes into consideration four levels of analysis: the system-,regional-, state-, and individual level. It is centred on a key decision maker, andapplies a cognitive approach for determining his or hers belief system through whichthe inputs from the other levels are filtered in order for the decision maker toconstruct a perception of reality, from which the decision is then formulated within.The framework is applied to North Korean and its leader Kim Jong Il. It sets outto explain his behaviour in the matter of their claimed nuclear weapons program, andhis decision to conduct a nuclear weapons-test, getting inside his head trying to figureout why he chose to do it and for what reasons.The conclusion indicates that the basic structure of the framework and its generalapplicability is sound, but that it needs further testing in order to make it perfectly solid..

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.
