Phycoremediation of pesticides using microalgae
Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and
mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity
in biosorbing heavy metals.
"Varder lekare sårad..." : Musik, politik och ideologi i tidigmedeltidens Norden
The aim of this paper is to illuminate and discuss the political and ideological aspects of Early Medieval Nordic music. Due to shortage of sources, this issue has been overlooked until now. Did Early Medieval Nordic music meet the requirements for political and ideological use? In what ways could music potentially be used politically and ideologically? Was music used as a political and ideological tool? This is examined by a contextual analysis combining music history and historical archaeology. The survey consists of a background account, focusing on the potential of music and some requests for political use, and three case studies, where musical reflections of societal tensions is investigated in folk music lyrics, Icelandic sagas and church art.
Sjuksköterkors uppleverlser av att bedriva palliativ vård i ordinärt boende
Aim. The aim of the study was to describe how nurses in home care experience to pursue palliative care in ordinary housing. Methods. The study had a descriptive design with qualitative approach and was carried out through semi-structured interviews with 14 nurses in home health care from two Medium-sized Swedish municipalities. The material was analyzed with manifest and latent content analysis. Findings. The underlying theme that emerged in the study was: Working with palliative care in the patient´s own homes is positive but challenging. Informants describe among other things that they perceived palliative home care as meaningful and that relatives have a central role in the palliative home care since they are close to the patient around the clock. The stress that emerges from the heavy work load and the long geographic distances are described as strenuous and to affect the care in a negative way. Informants describe the home environment as challenging as it is often not adapted for care and the collaboration with the palliative team is described to be experienced as both positive and negative.
Operationsklinikers riktlinjer och arbete med oavsiktlig anestesiinducerad hypotermi.
Background: Students, at a secondary upper school, attending a practical programme have a lower physical capacity than students from theoretical programs. Our physical self-esteem has a great significance for our motivation in being physically active and thereby also for our health. The purpose: of this study is to find out if there is a difference between perceived physical self-esteem and objectively measured physical activity between students attending a practical programme and a theoretical programme. Method: Four classes, in a Medium-sized town in the southeast of Sweden, participated in the study, two classes from practical programmes and two classes from theoretical programmes. All the students were in their final year at the upper secondary school, when they were part of the study during the autumn of 2011.
Hallsta Pappersbruks virkesförsörjning
Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
Etik, öppenhet och relationer : Svenska PR-konsulters syn på sitt arbete
This essay concerns PR-consultants and their view on their work. The purpose was to find out which type of communication they use in contact with the target. By target, we mean the group of people the employer wants to reach with help of the PR-consultant. For example: Jägarförbundet wants to get help from a PR-consultant to influence someone in the government so that Swedish hunters can shoot more wolves, than the target group is the one in the government. We also wanted to find out if the PR-consultants are aware of the image the public have of them and if they are trying to change it into a more positive one, by using more ethics, openness and to have more focus on the relations aspect. PR in the future with new social media (like Internet) was also a subject, where we wanted to know how much they involve social media in their work. Our main questions were:How do PR-consultants relate to openness in communication, ethics and social media?Which one of Grunig?s PR-models is most occuring in the PR-consultants work? We made a qualitative study where we carried out interviews with six PR-consultants.
IT och globalisering. En essä.
Syftet med detta arbete har varit att undersöka huruvida informationsteknik skapar möjligheter för tredje världen att utvecklas eller om IT i stället ökar klyftan mellan industriländer och utvecklande länder. Centralt i min diskussion har varit frågorna om globalisering och IT kan bidraga till en ny politisk ordning som grundas på dialog och samtycke i stället för våld och makt samt om globalisering och IT kan bidraga till en mer rättvis värld. Teoretisk utgångspunkt har varit Andrew Linklaters teori om "the triple transformation of political community". Tanken bakom den tredelade transformation är att skapa ökade sociala relationer som är mer universalistiska till sin natur, mindre ojämlika samt mer känsliga för kulturella skillnader. I mitt arbete påvisar jag tendenser till att informationstekniken kan bidraga till ökad universalism samt till ökad känslighet för kulturella skillnader.

Rune Pettersson, professor i informationsdesign vid Mälardalens högskola, beskriver ämnet informationsdesign såhär:?In order to satisfy the information needs of the intended receivers information design comprises analysis, planning, presentation and understanding of a message- its content, language and form.
Atopon. En intersektionell studie över svenska gymnasieungdomars tal om religion, etnicitet, klass och kön
This master?s thesis problematizes how students in two Swedish secondary schools think and speak about, and relate to, topics such as gender, class, ethnicity, religion and sex, but also how they move in, make use of, and interact within, the school space. What categorizing and positionings, if any, can be found? Students in two Swedish secondary schools, in a Medium sized Swedish town, have been observed (using participant observation) and interviewed (open ended), the material was then examined with intersectional theory. A majority of the ethnic Swedish respondents position ?the religious? as ?superstitious?, ?frightening? and/or ?backwards?, also many of them equated religion with ?muslim/islam?, a greater understanding for the others religious outlook was shown by students with an ethnic background from outside Europe.

Hundfoder mot hjärnans åldrande ? kan det fungera?
Due to better nutrition, veterinary and overall care, pet dogs? lifespan has increased. With more old dogs we see more health problems associated with age, among those cognitive decline, leading to deficits in learning and memory, disorientation, anxiety and other altered behaviors. Cognitive decline can have severe negative impacts on the life of both dog and owner, when the dog for example forgets being housetrained or starts being awake at night.
Two pet food manufacturers have developed food with specific ingredients in order to improve cognitive functions or delay the onset of cognitive impairment. Hill?s Pet Nutrition has developed a dog food with supplements of a broad spectrum of antioxidants and mitochondrial nutrients, aiming to diminish oxidative damage in the brain, thereby maintaining brain function and improving learning ability.

Extra! Extra! En studie i urval och nyhetsvärdering av push-notiser
This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a Medium ? has acquired an ambiguous importance.
Omvärldsbevakning på bibliotek
The purpose of this article is to investigate how and from which sources librarians collect information on their profession with respect to factors that are important for their work. In order to achieve this goal, a questionnaire-based survey will be conducted at three Medium-sized central-public-libraries in southern Sweden. Using this survey, I wish to answer the following four questions: To what extent do librarians acquaint themselves with changes and developments within regional and cultural policy arenas important to their work? To what extent do librarians acquaint themselves with information using conferences and library debates that are focussed on changes and developments relevant to their work? Do librarians consider that they have enough time within the limits of their work hours to follow developments within the librarian profession, for example with respect to developments within information technology, and how would they appraise the future demand for information technology-based services at the library? From which source(s) do librarians collect information relevant to their work? The theoretical basis of this paper can be compared to a radar as it scans subjects-of-interest to the organization in the field of business intelligence. This investigation uses a quantitative method, with data collected via a survey consisting of 13 questions.
Comparison of four transport systems for enetric pathogens
ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.
