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..

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.

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. .

VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.
Användning av IT som resurs i sjukvården : En studie om interoperabilitet i vårdens eHälsosystem
Today significant resources are provided to improve the digital work environment within the Swedish healthcare to create efficiency, good work environment and patient safety. Despite this, major flaws are shown by the lack of communication between the eHealthcare systems. This becomes a stress factor among healthcare professionals because of increased administration and decreased physical contact with patients. The purpose of this study is to create a understanding of the concept of interoperability at different levels in the eHealthcare systems. This has been conducted through a qualitative interview study at a healthcare center where the respondents have been describing their digital work environment and the way it works today.
Kvinnodominansen inom folkbibliotekarieyrket i Sverige under 1900-talet - Uppsats baserad på en undersökning av förhållandena i Uppsala, Jönköping och Skara under åren 1938, 1958 och 1978
This essay is about possible causes to the female dominance in public libraries. We have focusedon the 20th century in Sweden and the development of public libraries during this time. Forthis purpose we have done a survey of three different cities, Uppsala, Jönköping and Skara,during three different years, 1938, 1958 and 1978. We have studied salaries, gender and titlesfor the employed at the head library in each city and then made comparisons between them.In conjunction, we have also studied how women were looked upon by the rest of society,regarding their education and work opportunities.To achieve a comprehension of the society's view of women we have, in the essay, put threedifferent theories of the so called "female nature" in center. The genderization in the labourmarket has also been set to discussion.A comparison between librarians, teachers at different levels, and postoffice employees, hasalso been made regarding their salaries during the years (1938, 1958 and 1978)..
Kurslitteraturens språk upplevs förlora betydelse så snart budskapet uppfattas av läsaren
Syftet med denna studie är att utforska hur individer upplever sin prestation och själva inlärningssituationen då kunskap som ska läras in på ett språk ska återges på deras modersmål i form av tentamen eller i andra diskussionssituationer. Sex personer intervjuades om deras upplevelser att läsa kurslitteraturen på ett främmande språk och sedan återge den inlärda kunskapen på deras modersmål, i detta fall, svenska. Intervjumaterialet analyserades utifrån induktiv tematisk metod. Ur analysen framträdde tre huvudteman: förståelse av innehåll, förmågan att kunna uttrycka sig och slutligen, översättningsproblematiken. Den första två teman visade att prestation inte anses bli negativt påverkad av att den inlärda kunskapen ska återges på modersmålet.
