Polydaktyli är en medfödd missbildning där en individ får en eller flera falanger mer än vad som är normalt hos arten. Defekten uppkommer under den embryonala utvecklingen och är sporadiskt förekommande hos häst. Hos människa tillhör den däremot en av de vanligaste hand- och fot- relaterade missbildningarna. Idag är kunskapen begränsad rörande den genetiska bakgrunden till polydaktyli hos häst. Forskningen om de genetiska faktorer som orsakar polydaktyli hos andra djurslag som t.ex.

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.

SCB gör en vakansundersökning varje månad, granskningssystemet för undersökningen ska eventuellt ändras till en metod som kallas för significance editing. Med den granskningsmetoden behövs ett jämförelsevärde för att kunna avgöra om enkäten är korrekt besvarad eller om ett värde är misstänkt och behöver granskas ytterligare. Uppsatsens syfte är att genom poissonregression ta fram en bra modell som kan generera detta jämförelsevärde. Ett antal hjälpvariabler togs fram och testades för att se om de passade i poissonregressionen och om de kunde förklara antalet vakanser. De hjälpvariabler som har använts är antal vakanser föregående månad, antal anställda på arbetsstället, dummyvariabel för Sveriges län och månaderna.

Bakgrund: Litteraturgenomgången visar att samhället genomsyras av heteronormativitet. Kunskapsbrister finns i utbildningarna inom sjukvården och i den kliniska verksamheten om möten med HBTQ- personer. En kunskapslucka kan identifieras om hur möten skapas mellan sjuksköterskor och HBTQ- personer på en akutmottagning. Syfte: Studiens syfte var att beskriva hur legitimerade sjuksköterskor på en akutmottagning möter HBTQ- personer. Metod: Deskriptiv empirisk studie med kvalitativ ansats, interaktiva samtalsintervjuer med sex legitimerade sjuksköterskor genomfördes och analyserades med modifierad innehållsanalys, editing analysis style.

This study investigates the difficulties that may arise for students as a consequence of differences that exist in mathematics education between different educational systems. The questions asked are when and why difficulties as a consequence of differences in writing or types of student problems may arise and in which way teachers and students attend to these difficulties. The focus is thus on the written parts of mathematics education and the questions are asked within the frame of general upper secondary education.In order to answer these questions, a sociocultural perspective based mainly on Sfard?s (2006) participationist theories together with Vygotsky?s (1999) general theories on development and learning is used. An important analytic tool is the discourse concept which in this context means a type of communication that brings some people together while excluding others from the communication.

The purpose of this master´s thesis is to examine how the cultural exchange function of Swedish libraries may be perceived on their websites. A further intention is to examine how the library websites are used at the present. Two quantitative web-based surveys have been sent out to a great number of Swedish public libraries. The first survey was directed to the webmasters of the libraries, in order to review the different services offered by the Swedish library websites of today. The second survey was conducted with library directors, in order to visualise what services they consider ought to be present on their own library website.

This thesis should be regarded as an integrated research synthesis. The purpose has been to analyse how the literary sociologist Lars Furulands model the literary process correlates in relation to todays book market for fiction. The central problem has been: In what different ways can some of the main actors featuring in Furulands model of the literary process use, produce or provide copyright protected works of fiction which are electronically distributed? Three questions have been considered to penetrate this problem: In what different ways can to judge from some projects which have been carried through at common public libraries electronic works of fiction be provided to their presumed readers? What reasons could there be as it appears in a number of texts that four Swedish authors have chosen to disseminate their works of fiction by the aid of the Internet? Which main functions may, according to current research, be supported by electronic media in connection with editing and retail of fiction? During this study a picture of two quite disconnected processes of publication has materialized. These processes seem to proceed parallelly to each other, without any close contact, in a traditional respectively an electronic circuit.

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts. In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate. The life cycle of P. brassicae is not well understood.

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.

The purpose of this study is to investigate how twelve middle school teachers use educational tools and what influences their choice of educational tools in Swedish language writing instruction. To answer this purpose, three research questions were formulated: What does writing instruction look like for middle school students according to the teachers in the study? What influences teachers' choice and use of educational tools in writing instruction? What opportunities and challenges do teachers experience in Swedish language writing instruction when using different educational tools? Twelve teachers from variously sized municipalities and with different experiences participated in the study through purposive sampling and convenience sampling. The chosen method is qualitative semi-structured teacher interviews. To analyse the results, this study employs analytical tools from the sociocultural perspective, using concepts such as mediation, appropriation, the zone of proximal development, and scaffolding. The results show that both analogue and digital tools are used in the teachers' writing instruction. The choice of tools should be based on pedagogical considerations, with an emphasis on social interaction and collaboration during the learning process.

Although I myself haven?t been bullied per say during my school years. I?ve sure been teased and occasionally felt left out. On the other hand ? who hasn?t? And that as well is my point.

The purpose of this study is to investigate the teachers? described experiences of advantages as well as disadvantages of Arne Trageton?s write to read-method (?ASL?) in contrast to the code-oriented traditional way of teaching. The aim of this study is furthermore to depict the teachers? opinions on whether they experience that the ASL-method is unfavourable for students in general. This study will also investigate the teachers? standpoint regarding choice of reading and writing method.
