Benthic diatoms are used in Sweden for monitoring water quality in run-ning water; the method is also frequently used in other countries in Europe. One of the problems of the diatom method is the need for sedimentation of the fresh sample, to be able to decant the over standing water and add alco-hol as a preservations solution. To my knowledge, no results have been published about how long the settling time must be to ensure that the ben-thic diatoms really have settled down to avoid a loss of the diatoms when decanting the over standing water. The aim of my investigation was to improve the Swedish method where the benthic diatoms are used for water quality monitoring. I wanted to find out the appropriate time necessary to wait until all diatoms have settled down before decanting the over standing water. First, fresh benthic diatom samples were taken in the river Fyrisån and the lake Mälaren on different days. After arriving in the laboratory, I waited three different times (30 min, 60 and 180 min) for the diatoms to settle.

For youths leisure activity the organized sport is vital. Young people become increasingly sedentaryand the healths of young people are the various municipalities responsibility. In Eskilstuna, thehandball is very popular but there are only three grounds that meet the standards of the dimensions ofa handball pitch, 40x20 meters. The same dimensions are used by floorball. Eskilstuna municipalityowns one of these, the other two is privately built and owned and the municipality rents time in thehalls.IF Guif and HK Eskil are two handballclubs in the central part of Eskilstuna.

Ill health takes different expressions during different periods in life and habits during the early years affect the health during the rest of the lifetime. Bronfenbrenners ecological systems theory has been used as a theoretical starting point in this cross-sectional study. The aim of this study was to identify differences in self-rated health and health-related factors between boys and girls and between the compulsory school and the upper secondary school in Sundbyberg municipality as a basis for the planned activity in the Young Women?s shelter in Sundbyberg, as well as in other municipalities A questionnaire consisting of 24 questions based on different variables has identified disparities in health and health-related factors between boys and girls in Sundbyberg municipality (n=323). This paper found pronounced differences between the sexes in terms of sex and relationships, security, emotional support and psychosomatic complaints.

AbstractThe aim with the study was to describe and to compare nurse students' views about importantcaring behaviors in order to give good caring. An empirical comparative study wasimplemented on a college in the middle of Sweden. Nurse students in the beginning and at theend of their education sorted and prioritized 50 caring behaviors (CARE-Q). The result showedthat the students' description of important caring behaviors has many similarities. However, theresult also showed that there were significant differences between the student-groups where thestudents at the beginning of their education rated several caring behavior as significant moreimportant than the students in the end of their education.

In support to a decision to be made by the Swedish central competent authority on a minimal amount of straw for conventional growing-finishing pigs, a study using 168 pigs provided 7 different amounts of straw (20, 40, 60, 80, 100, 200 or 300 grams/pig/day) was performed. The straw was provided either once or four times per day. Detailed behaviour observations were made using focal animal sampling and continuous recording for one hour between 9 and 10 am and again between 3 and 4 pm. The data analysis is presented in three ways: broken stick model, polynomial trend line and logarithmic trend line. No method was suitable on its own but the use of all the methods simultaneously was found to portray the data in the best way.No significant differences were found when comparing pens provided with straw once or four times per day.

Abstract Squares, these public rooms have always fascinated me. I find them interesting because of their variety in shapes, functions, design etc. Stortorget in Lund is one of Sweden?s oldest squares, this essay is dedicated to this particular square. Of all the possible ways that you could approach Stortorget in Lund I have decided to do it from an urban design point of view.

Through the ages mankind has developed and tested a cascade of varying weapons ofwar, large and small, and has has striven to push these creations to the limits of theirtime. A grand example of this are the medieval siege engines that have changed shapeseveral times over the centuries. After all this time the eciency of these siege engineswill have reached their peek.

Today the Internet is used more and more as a transportation for information. Much of the information is confidential and should not be read by those not privileged. To protect the information from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications.

Cattle have a species specific movement pattern when lying down and getting up. They need sufficient space for their heads to perform these movements normally. The aim of this study was to investigate the lying down and getting up behaviour of beef bulls at a Swedish farm operation. The hypothesis was that bulls older than 10 months (over approximately 400 kg) were disturbed by a horizontal front rail and that the time to lie down and get up differed from what can be regarded as normal based on earlier scientific studies. The bulls were Swedish Red and White (SRB), Swedish Friesian (SLB) or crossbreeds of these two, and were kept in a cubicle system with a stall front design where there was a horizontal rail 40 cm above the stall floor.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Titel: QR-koden ? ett nytt marknadsföringsverktyg med potential Författare: Eric Karlsson och Oskar Kristiansson Handledare: Klaus Solberg Søilen Nivå: Kandidatuppsats, Marknadsföring (15 hp), VT 2012 Nyckelord: QR-koder, marknadsföringsverktyg, interaktion, incitament, strategi, Quick Response Codes, marknadsföring, print media, smartphones, annonsering, ROIProblemformulering: Hur bör företag använda sig av QR-koder i sina marknadsföringsaktiviteter?Syfte: Syftet med denna uppsats är att, med utgångspunkt i den teoretiska referensramen och en kvalitativ studie av fem svenska företag, kartlägga hur QR-koder bör användas i marknadsföringsaktiviteter. Vidare vill vi identifiera fördelar och nackdelar med QR-koder för att se vilka implikationer ett lyckat respektive misslyckat användande har för företagen.Teoretisk referensram: Här presenterar vi olika teorier för att förstå begreppen som ligger bakom samt hjälper till att definiera fenomenet QR-koder och användningen av dem i marknadsföring. Teorierna är även behjälpliga vid vår analys av den empiriska datan.Metodik: Vi har valt en deduktiv ansats till vår uppsats som innebär att vi tittat på tidigare nedskrivna teorier och information för att kunna ta ställning till hur vi ska ställa frågorna till de företag som vi vill intervjua i vår kvalitativa undersökning.Empirisk studie: I empirin presenteras svaren på de djupintervjuer som utförts med våra fem fallföretag.Slutsats: Vår slutsats är att QR-koder bör användas på tydligt, informativt och lockande sätt utefter en tydlig strategi, och att de gå kan gynna ett företag ur ett marknadsföringssyfte genom att de vid ett kvalitativt användande kan nå och engagera fler konsumenter och därigenom öka sin omsättning och varumärkeskännedom. Används QR-koder däremot på fel sätt kan varumärket ta skada istället för att gynnas..

The aim of this essay is to examine what happens when Veronica Roths Divergent-trilogy is read with a lutheran theological pre-understanding. Using reader-response theory and lutheran theology written for and in a post-modern context, three lutheran figures of thought are presented as one way of understanding the trilogy. The conclusion is that it is possible to reveal lutheran ideas concerning justification, guilt, forgiveness, mercy and self-sacrificing love in the Divergent-story. .
