Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.

Previous research confirms that there is a major decline of pollinators worldwide. Investigations have mainly focused on pollination services in the agricultural landscapes and therefore, there is a lack of knowledge on the effects pollinators may have in urban environment. This paper examines the presence of honey bees in central parts of Stockholm, Sweden. The study presents what conditions, possibilities and motives there are behind the phenomenon of urban bee keeping. I found ten locations with beehives and a total of 18 hives within the delimited area. Nothing seems to indicate that conditions may limit the presence of honey bees.

This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.

At Kungliga Biblioteket in Stockholm you can find over 40 000 letters sent to Selma Lagerlöf. Many of her readers wrote and asked for her help, and the letters show that she helped a lot of people with money as well as with writing advice. People from all over the world asked her for money to be able to study, to finish their written works, or just to get through the day. Others want her to read their texts and poems, because they wish to hear her opinion or wonder if she can put in a good word for them at some publisher. This essay illuminates the question why so many people had this confidence in Selma Lagerlöf.

Denna studie har undersökt huruvida det Àr möjligt att pÄ Nasdaq OMX Stockholm generera systematiska överavkastningar i samband med att aktier börjar handlas exklusive rÀtt till utdelningar. Samtliga utdelningstillfÀllen har undersökts under perioden 2007-2011 vilket givit en total observationsmÀngd pÄ 699 stycken tillfÀllen. Genom att ha tagit hÀnsyn till eventuella marknadsfluktueringar och vikta dessa med bolagets unika risk, i form av betatal, har resultaten Àven justerats för normalavkastningar under den undersökta dagen. Resultaten frÄn Large Cap, Mid Cap samt Small Cap har sedan jÀmförts. Resultaten visar att överavkastningar Àr möjliga under dagen dÄ aktien slutar handlas inklusive utdelning, samt att effekten Àr större för de mindre bolagen..

The development aid from Sweden to developing countries is a activity thatinvolves a great deal of monetary founds as well as an opportunity to influence the environmental situation in a partner country. ItÂŽs also an opportunity to promote Sweden's values in a field like the environment, setting a good example is important. This thesis aims to evaluate SidaÂŽs environmental policy and find out if there in fact is a Environmental Policy Integration Policy (EPI) taking place. EPI is a policyimplementation theory that emphasise the importance of the total integration of the environmental in the organisation as a whole. To identify this I will use a theoretical framework of indicators invented by William M.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Can an increased intake of omega-3 fatty acids have an effect on testosteronelevels in women with PCOS?Author: Ylva Dernbrant och Helene HagenborgSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundPolycystic ovary syndrome affects women of fertile age and consists of elevated testosterone levels and increased insulin resistance along with effects on ovulation and fertility. The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

Bakgrund: Kvalitetsutveckling inom vÄrden pÄgÄr i hela vÀrlden. Internationell forskning indikerar att förbÀttringscoacher kan vara en framgÄngsfaktor i förbÀttringsarbetet. Det Àr i dag oklart hur man kan utveckla interna coacher till att stödja kontinuerliga förbÀttringar. Studien utvÀrderar ett lokalt, tvÀrprofessionellt coachprogam inom vÄrd och omsorg i ett geografiskt omrÄde i Sverige med en etablerad samverkanskultur. För att frÀmja ökad kundcentrering ingick en pensionÀr i programmets planeringsgrupp.

The purpose of my study is to examine if the total study results differ between music classes and regular classes. Are there higher grades in music classes? If so, what are the causes for this? I chose to make an inquiry at two schools in different town districts, with music classes. At those schools I also collected data of pupils grades, and was informed by the principals and the music teachers about the activities. The number of respondents were ninety.The inquiry showed that the grades were markedly better in music classes, and that you can see great differences in well-being, parental engagement and ambition level, compared to regular classes.

Arbetsuppgiften var att ta fram rekommendationer pÄ driftpraxis gÀllande argonspolning vid en efterbehandlingsstation pÄ SSAB TunnplÄt AB i LuleÄ. Rekommendationerna skulle gÀlla tiden för slutspolningen efter att behandlingen av stÄlet, sÄsom tillsatser av rÄmaterial för att uppnÄ rÀtt kemisk analys samt temperaturjusteringar för att optimera gjutningen, var fÀrdig. Syftet var att minska mÀngden oxidinneslutningar i EHS-stÄl som orsakar igensÀttning vid gjutningen, samt uppnÄ kundens förvÀntningar pÄ rent stÄl. Insamling av prover (Total Oxygen Sample) och mÀtningar (syresond) har gjorts vid efterbehandlingsstationen, CAS-OB, och i gjutlÄdan. Med hjÀlp av proverna har syrehalten berÀknats vid noterade spoltider.

The number of parties in the Swedish parliament has increased from five to eight during the last twenty years. The political agenda is still based on a two-block system with the consequences that the number of parties in each block has increased. To be represented in the parliament, a party needs at least four per cent of the total votes in the election. If only one party fails to achieve that, the whole block will lose the election to the other block. This could encourage voters to vote tactically for the small parties in the block to ensure that the block wins the election.

We investigate if the size of goodwill compared to total assets has any effect on the shareholders return on companies listed on the Swedish Stock market. We put up two different hypotheses with a foundation from previous research and later dismiss one of them. Our evidence does not show any indicators that the size of goodwill have an effect on the shareholders return, which brings us to believe that there, from a share holders point of view, isn?t any need for concern regarding the standards about accounting for goodwill as stated by IFRS. .
