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.

The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.

This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.

This thesis is conducted together with the environmental- and health department in Halmstadcommunity. The thesis is about allowance of bedding and water supply for pig farms inHalmstad community. These farms are chosen randomly from all of the pig farms inHalmstad community. It includes inspection of 27 pig farms and writing of a report. Duringthe inspections I study the amount of bedding, what kind of bedding, water supply andinjuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting.

The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

The purpose of this thesis is to investigate the ways in which emotion regulation and mood affects risk taking when it comes to decision making competence. Emotion regulation is an essential part of the attachment process, the development of an autonomous self and functional stress coping systems. Research indicates that there is a relation between a distorted emotion regulation and some psychological disorders like depression, PTSD, anxiety disorders and borderline (or instable emotional personality disorder). There is a definite need to analyze the relation between emotion regulation and decision making competence since it is relatively unexplored. A digital questionnaire was distributed amongst the participants.

We all know that water is very important for both animals and humans. When we are weaning the piglets from the sow we must guarantee that the piglets can start to drink more water instead of sow milk. The first thing to check is always the quality of the water that is to be used. To secure that, you must take a water sample. If the water is inadequate it can bring a lot of problems and diseases.

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.

Background: Many different parties in the society are affected by the financial information delivered by the companies. Therefore, different interests want their ideas to have an impact on the accountning standards. The construction of the accounting standards are illustrated as a pure political process, where lobbying and conflicts of interest are determining factors. Purpose: The purpose is to understand the underlying interests behind regulation of financial accounting in Sweden and how these interests are manifestated in the establishment of accounting standards. Method: The thesis is designed as a casestudy of the regulation process which induced the legislation of the Årsredovisningslagen 6 kap 1 § 3st.

To business owners and consumers electronic commerce means new conditions and possibilities. Often and specially at the Internet information between consumers and sellers is asymmetrically distributed. Among the consumers there is a shortage of confidence in electronic commerce. In order of a positive development of electronic commerce it´s important to find a solution to the shortage of confidence. Confidence may be created by legislation or by self- regulation.

Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.

The purpose of the thesis is to increase the knowledge of the deregulation of the mobile telecom market in Sweden, with focus on the time after the Electronic Communications Act (EkomL), by: (1) Describing the thought behind the Electronic Communications Act. (2) Assess how the National Post and Telecom Agency (PTS) has acted. (3) Assess how the operators have reacted. (4) Investigate the regulation?s effects upon competition.

The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking water production, in case the commonly used water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their water sources and for many sources the protection was not satisfactory.
