Ny princip för spänningsreglering i Fortum Distributions mellanspänningsnät i Stockholm.

The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.

Avblås för torkning av kabel

This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.

Whispers in the forest : a field study about communication within Vi-agroforestry

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

Barns delaktighet i frågor om umgängesstöd : en studie av elva tingsrättsdomar

The purpose of this study was to examine children's participation in court proceedings on supervised visitation and to analyse the descriptions of children in court verdicts. Eleven verdicts concerning supervised visitation resolved in 2014 were collected from two district courts in Stockholm County and studied with a qualitative textual analysis. The material was analysed with participation levels influenced by the ladder of participation for children developed by Roger Hart and with the theory of sociology of childhood. Our findings showed that children's opinions were mentioned in eight of the verdicts. In four verdicts the children's will influenced the courts decisions.

Lösenord till Framtidens bibliotek : en jämförelse mellan Ronneby och Sölvesborg folkbibliotek när det gäller IT-utveckling och bibliotekets roll i informationssamhället

Our aim with this study has been to show the central factors that we consider have had animpact on public libraries in the "information society". We have studied two communities in the south of Sweden, Ronneby and Sölvesborg. These two communities have both started a development to the IT society, a society where information plays a great role, where the technique is the tool that supplies information.Ronneby community had early the aim to be the chief Swedish information center. A priority on information technology has therefore been obvious for them. Sölvesborg community has had another method and time schedule towards the IT society.We have been studying the documentation of aim and the strategy for IT development in different levels.

Avskiljning av uran från dricksvatten med reaktiva filter :

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

WHITE HOUSE/GREEN HOUSE - En processpårande undersökning av klimatfrågan i USA

This thesis examines the process of securitization of the environmental issue in the United States. By using the theories of sectoral security and securitization by Barry Buzan and Ole Waever, commonly known as the Copenhagen school we go beyond the traditional security frames and examine where the environmental issue in the United States stand today within the securitization spectrum. The securitizing spectrum includes three levels in which an issue can be place: non-politicised, politicised and securitized.The problem, which we wish to address, is if there is a movement of the environmental issue in the United States towards becoming a securitized issue. In the light of these circumstances we also wish to explore who is behind the movement and also find out where the issue stand today. We do believe that Al Gore is a securitizing actor and examine his role in the movement of the environmental issueWe have come to the conclusion that there is an ongoing process of securitization in which the environmental issue have moved from being politicised to becoming securitized..

Den stygga trädgården : En sinnlig tolkningsansats med utgångspunkt i Helen Chadwicks Cacao och Bad Blooms

The purpose of this essay is to discuss what a sensual interpretation of art is and what it should include. The discussion is based on an attempt to do a sensual interpretation of the Greek-British artist Helen Chadwick?s Cacao and Wreaths to Pleasure. Chadwick was an artist working with well-known materials in new and unexpected ways.

En inventering av hälsoläget hos amerikansk bison (Bison bison bison) : i svenska besättningar

American bison (Bison bison bison) is a new species in Sweden and was introduced in the year 2000. In this study the result of an interview and a field investigation is presented. The aim was to investigate the health and parasite status in Swedish bison herds. The most common reason to begin with bison breeding was meat production and/or sale of breeding animals and tourism. The Swedish breeder?s experience of bison is that they in general are healthy.

Serum Amyloid A as a possible marker of health and disease in non-domesticated mammals : a retrospective pilot study of SAA levels in dolphins, elephants and tapirs at Kolmården Wildlife Park

The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and thus the stress for the animal and also in order to increase the possibility of starting relevant treatment early on. The aim of this pilot study was to determine whether Serum Amyloid A (SAA) could be a measured in blood samples from bottlenose dolphins (Tursiops truncatus), Asian elephants (Elephas maximus) and South American tapirs (Tapirus terrestris). SAA rises to its maximum about 24 hours after the introduction of an inflammatory agent in companion animals. This also correlates with the estimated time it takes for animals at Kolmården Wildlife Park to be examined and having blood samples collected after being observed as sick. The study also evaluated whether the Eurolyser SOLO, using a turbidometric immunoassay (TIA) developed for human diagnostics, could be used for such analysis. This pilot study was a retrospective analysis of SAA in convenience sampled frozen serum, collected from dolphins, elephants and tapirs.

Arbetsrelaterad stress inom äldrevården : Anställdas upplevelser enligt Theorells krav - kontrollmodell

Abstract The main purpose of this study was to investigate if and how the employees in elderly care experience stress and which underlying causes they understand to be important in their work situation.

Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan

An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.

"Jag brukar jämföra källor med varandra." : En studie i gymnasieelevers kritiska tänkande

The main purpose of this bachelor thesis is to examine the existence of criteria and to what extent high school students use these criteria when they are collecting information for a school assignment. I also compare students attending different high school programmes with each other and compare students on different levels of education.I have done a quantitative study with 284 students in which the students have filled out questionnaires.The result shows that the most common way to evaluate information is to compare sources with each other. Students also look at how the information is written, and they want the information to be detailed and easily available. More seldom used criteria include consideration of the authority of the writer, determination of how up to date the information is, and gauging the perspective of the information.The result also shows that students attending a high school programme that prepares them for higher education are better at evaluating information than students attending a high school programme of vocational preparation. Students at a higher level of education are also better at evaluating information than students at a lower level of education. .
