Molecular analysis of insecticide resistance in pollen beetle (Meligethes aeneus)
The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.
Upplevelsen av depression hos ungdomar och unga vuxna
Depression är ett förändrat känslomässigt tillstånd som bland annat ger symtom som orkeslöshet, trötthet, ilska och ledsenhet. Forskning pågår om vad som orsakar depression. Teorierna är många, men en förklarar depression som en brist på monoaminer. För att förhindra en försening i den konstruktiva utvecklingen som råder under ungdomstiden är det viktigt att behandling sätts in i tid. Vanligaste behandlingen är farmaka samt psykoterapi.
Immunhistokemisk undersökning av paraffinbäddade celler från pleuravätska som kompletterande underlag för diagnos av cancermetastaser
Background. Immunohistochemistry is a useful method in the differential diagnosis between pleural mesotheliomas and metastatic adenocarcinomas in the pleura. Cytokeratin 20 and 7 have been used successfully as markers in studies determining primary location of adenocarcinomas from metastases. The current study is a complementary research of archived paraffininbedded material of cases with cancer origin. This study contributes a bigger statistical material that may facilitate the search for unknown primary site of adenocarcinoma by identification of metastatic cells in the pleura.Methods.

Hur påverkas sexualiteten av en stomi? : Individers upplevelser
Bakgrund: Omkring 25000 individer i Sverige lever idag med en stomi. Stomin kan ha en påverkan på den sexuella hälsan då den kan orsaka problem vid sexuella aktiviteter. Den kan också hota vuxenrollen på grund av förlusten av att inte kunna konrollera tarmen. Sjuksköterskans uppgift är att ge vägledning, utbildning och information om sjukdomsförloppet och den sexuella hälsan. Att prata om sexualitet inom sjukvården kan dock vara problematiskt då det är ett känsligt ämne för både patient och sjuksköterska.Syfte: Att beskriva individers upplevelser av sexualitet i samband med stomi.Metod: Litteraturöversikten baserades på tio vårdvetenskapliga artiklar som hämtats från databaserna CINAHL Complete, PubMed, Medline, Academic Search Complete och DOAJ.
Att organisera beståndet eller ?Äntligen hittar man!? : om hylluppställning och exponering på Arkenbiblioteket
The aim of this master?s thesis is to examine how libraries can organize their collections in terms of library shelving and displays and to what extent these activities stem from a desire to create a user-friendly library. The thesis is based upon a case study of Arkenbiblioteket in Sweden and the material consists of a literature study and qualitative, semi-structured interviews with three librarians at Arkenbiblioteket. The theoretical framework consists of theories on information-seeking behavior, classification and displays. These theories form the basis of the analysis of the empirical material.The main reason for the changes in shelf arrangement at Arkenbiblioteket was a desire among the library staff to create a user-friendly library.
Fri utfodring av halm som strategi för att förhindra stereotypier hos uppbundna kvigor :
At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle.
The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals.
Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.
It´s a way of understanding the universe while leaving the universe unexplained : Sökandet efter det autofiktiva jaget i Jeanette Wintersons Oranges Are Not the Only Fruit
In this essay I examine the auto fictive self in Jeanette Wintersons Oranges Are Not the Only Fruit. I do this through a close reading of the novel using Mieke Bals narratological terms;narrator, story, fabula, time and order. These narratological terms have been merged together with central themes of the book. I look at the readers understanding of the novel, the relation between fairytale and realism, symbols, intertextuality, the mother-daughter relationship and silences and I analyze these themes in their relation to autofiction and the auto fictive self. Gemma Lopez Seductions and Narratives has been a key reference, mainly her theories on self-creation in narratives, and the construction of the self, trough language. The narrative is the place where the self can transgress and reshape, which gives the narrative a subversive power. I analyze this presumed power, and look at how the story shapes an opportunity for the subject to see itself.
Rehabilitering av fotledsdistorsion för en effektiv återgång till idrott: en litteraturstudie
Fotledsdistorsion är bland den vanligast förekommande skadan inom idrotten, där symtom som smärta, svullnad och funktionell instabilitet oftast blir en följd av skadan. Beroende på hur allvarlig skadan är kan det innebära långa tidsperioder ifrån idrotten. Det finns olika rehabiliteringsmetoder efter fotledsdistorsion där oftast PRICE ingår. Syftet med studien var att granska den vetenskapliga litteraturen avseende effekterna av rehabiliteringen efter akut eller subakut fotledsdistorsion. Metod: En litteratursökning genomfördes i databaserna Academic Search Elite, CINAHL, PEDro och Pubmed, vilket resulterade i att 25 artiklar inkluderades.
Mot en delad framtid? : Mendeley som exempel på vetenskaplig kommunikation online
The last few years have been characterised by increasing online communication and the emergence of social media, made possible by Web 2.0. In society as well as in research, social media is used for knowledge produc- tion and networking. One example of this is Mendeley, a social reference management tool. With answers from users all over the world, this study investigates the use of Mendeley, if the respondents use other social media and if all of this affects scientific communication. The aim is also to study what the respondents think about the future of scientific communication and if this can be related to current tendencies.The theoretic framework for this study is based on Leah Lievrouws research on the Cycle of Scientific Communication and the relationship between the ?Little Science 2.0?-scenario and the ?Big Science Retrench- ment?-scenario.A qualitative web based survey was conducted (41 answers) and complemented with an interview with a professor in environmental sciences.

The fight for each pupil gets more and more important every term and it has now become real big business.Today?s youth is imprinted by a growing individuality and everyone knows that equableness is something very important.
VÄRDERING OCH REDOVISNING AV FÖRVALTNINGSFASTIGHETER I KONJUNKTURNEDGÅNG
In the year of 2005 the international standard IAS 40 came in to use in Sweden, this lead to an opportunity for the corporations to choose either to evaluate their investment properties according to the historical cost accounting principal. The model contains the obtaining price with reduction for the planned writing off. The alternative that IAS40 offers is the fairvalue principal, which evaluate the investment properties by consideration of the income versus outcome and surrounding factors for every accounting periodSince the fairvalue is buildt on numbers the corporations them self choose what to publish and for how long the value depreciation should be lasting before it should be taken up as an unrealized value change in the reporting material. This means that there is a big chance that the evaluation can be distortedSince we just recently have had strong cyclical variation and are on our way from an excess boom into a weak economic climate, this will be the first study performed about fair value in a weak economic climate since the adoption of IAS40.The purpose of the essay is to find out how well the booked value of investment properties owned by corporations listed on the Swedish stock market accord with the fairvalue that the market and the Swedish property index indicates on. To be able to test this connection we gathered information from the corporation?s annual reports which we compiled to see how the market comprehends.
