The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.

 This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.

This thesis examines why working time preferences differ between workers and nations, and explains the effect of working time regulation and working time flexibility on negotiating work-life balance. In five separate sections the following working time issues are examined: the number of hours worked by workers in Europe; factors affecting individual working time preferences; how working time preferences are negotiated in the national industrial relations systems of Sweden, France and the United Kingdom; how the institutions of the European Union have influenced working time negotiations through the Working Time Directive; and the benefits and practices available to organisations implementing working time flexibility. Broadly this paper views working time preferences as being a highly personal and influenced by factors such as wages, taxation, culture (national and workplace) and non-work responsibilities. It is argued that negotiating a preferred working time pattern is essential to achieving work-life balance and when such a balance is achieved, workers are more healthy, motivated and committed to their employer. Essentially this provides an incentive for businesses to voluntarily implement working time flexibility beyond the regulatory standards..

Our aim with this thesis was to closer study business intelligence to be able to present an overview of both the concept and the phenomenon. We have also developed a framework that show how business intelligence can be used effectively. We think that our framework can be of help to under-stand the areas which constitutes the core of business intelligence. We think that the framework we have developed is a good basis for the im-plementation of business intelligence in an organisation and that it also can be of help in the daily business intelligence work..

Due to the fact that bottled water has negative impact on the environment,Elite Hotel hasdecided to stop serving bottled water in their restaurants. Since Swedish tap water is regarded tohave great quality,Elite Hotel wants to look at the possibilities to carbonate their own sparklingwater and serving it in fancy carafes. This Master of Science thesis is about constructing a costefficient water carbonator system that suits Elite Hotel?s need specification. This thesis alsocovers other water refinement criteria.The work has been divided into three parts.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Directive 2006/54/EG from the European Union concerns the equal rights between men and woman and the principle of equal rights. The purpose of the directive is that the member states provide the equal rights between men and woman. Affirmative action is one exception from the principle of equal rights which is settled in directive 2006/54/EG, article 3. The purpose for the affirmative action must be to encourage the equal rights between men and women.EU has specific criteria to use affirmative action, which is created by praxis of the Court of Justice of the European Union. These criteria are that the affirmative action must involve an objective assessment, there must be equal qualifications between the person which is affirmative action and the person who is not, the positive action cannot be automatically decisive and this special treatment should be proportionate to the purpose.

This study in Environmental Science examines the amendment of the EU-Directive on. Greenhouse gas emission allowance trading. The Directive is to be considered as a tool for fulfilling the obligations that the Union and its member countries have taken on through the 1997 Kyoto agreement together with the protocols proposed at that time. The flexible mechanisms of the protocol are intended as instruments for limiting the climatic changes arising from anthropogenic sources, emission allowance trading being one of these mechanisms. The results presented here consist primarily of an analysis of interviews with various experts in the field of emission control concerning the possibilities and problems attending the process of implementation.

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

AbstractThis essay is about what rights that a consumer has, after it?s been to a beauty-shop getting a treatment somewhere on her body. We were interested to see what kind of regulations that could be useful if a problem occurred after or during treatment. There are several risks with these treatments.The last decade these kinds of treatments have increased, due to people being vain and so aware about there looks. We started to investigate what type of rights the consumer generally has when it?s about a service.

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

How to motivate yourself to learn has always been an area of interest, gamification has become a way of capturing and enhancing ones motivation. But how should the learning applications be designded to maximize the users motivation? This paper adresses wether Yu-Kai Chous framework Octalysis, is applicable on learning applications. The study is conducted by using a modified set of heuristics that are applied to the evaluated applications to gather data that is then used to evaluate the framework. The paper concludes that the framework can be used to evaluate learning applications but it should be modified to improve the results.
