Androstenons fysiologiska roll hos grisar

It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.

Två år efter restaurering:Vad har förändrats i bottenfaunan?

The aim of the study was to examine if the benthos in a restored portion of a small lowland stream south of Linkoping differed from two non restored reference areas two years after restoration. The reference areas were one stretch downstream and one upstream stretches of the restored stream. The benthic invertebrates were collected using standardized kick sampling. In order to classify the communities and estimate any differences, three different indices were exercised. In addition rank-abundance curves and checklists were used to get a picture of species composition.

Broar, länkar, gränser. Kultur, makt och marginalisering i diskursen om linkworkers/brobyggare

Abstract:The aim of this study is to critically analyse the discourse of linkworkers, a integration project in a ?multicultural? school in Malmö. In the project, four persons with different ethnic / cultural background where employed to work as a link between the school and the parents, and between the Swedish culture and the children's and the parent's ?original? culture. My material consists of evaluations of the project and interviews with school staff.

Kan Olikheter ena? En studie om sociala rörelsers potential att skapa dialog

In the process of globalization, identity has become one of the central factors.An understanding of the difference that makes up our society has made thequestion of weather is it possible to envision a society where difference is thecommon ground, one that has been up for contest. To answer this we need to seeif this kind of democracy is possible at all. For this I?m turning to the socialmovments who while they are working close to the reality also can give us somereal answers. Therefore I have looked at how social movements adress identity,difference and conflict and concluded that three things are crucial in organizing ongrounds of difference.

Mångfald, makt och välvilja. En diskursanalys av intentioner och synsätt bakom integrationspolitiska åtgärder

The aim of my study is to critically analyse the discourse behind two different integration projects in Sweden, by using post colonial theory. My hypothesis is that many projects intended for increased integration includes a view of immigrants as the ?Others? which can be seen in how one talks about integration and culture in the discourse behind integration projects.The first of these two projects aims at increased diversity in the cultural sphere, organized on at state level. The purpose of the second project is to increase the communication and results for schools in areas with a high rate of immigrants in Malmö. In my study I make a discourse analysis of the discourse behind these two projects and study how they are motivated and how one conceptualise culture and integration in these documents.

Alternativ splicing: en process som medför att flera olika mRNA-transkript bildas från individuella gener

This review article presents the splicing process during messenger RNA maturation and how it is regulated by different Cis-regulatory RNA-sequence elements and splicing factors. A more detailed description of the process alternative splicing and its importance to the function of genes from the model organism Arabidopsis thaliana is also given. A single eukaryotic gene can by the process alternative splicing (AS) give rise to a number of functionally mature mRNA-molecules, which in turn encodes for structurally and/or functionally different proteins. During the course of evolution, the process alternative splicing has thus shown to be effective in increasing transcriptome and proteome diversity of most eukaryotic organisms. This suggests therefore that the dominant theory in molecular biology, a gene encodes for a protein, needs to be corrected.

Filosofen som arkitekt : Subjektivitet och metaforik i Discours de la méthode

In this paper, I have proposed a way of interpreting the philosophical subject of the Discours de la méthode that has remained relatively unexplored by contemporary commentators. By investigating the subjectivity that is expressed through Descartes? use of architectural metaphors, I laid bare some of the difficulties inherent in its discursive structure, as well as suggesting that the cogito in fact repeats and inscribes itself into this structure. In this context, the metaphor of the road (or travel) takes a supplementary role in relation to the architectural metaphor, marking the very conditions of existence of the architectonic subject. The subject, in order that it may establish itself as ?pure? and ?independent? thought, is dependent on a certain ?forgetfullness?; that is, only by forgetting its constitutive dependence on the diversity and historicity that is signified by the metaphor of travel, can it establish itself as its own source.

Registrering och avel för brunstvisningsförmåga hos mjölkkor

Dairy farmers using artificial insemination (AI) are dependent on effective oestrus detection. In Sweden, AI is used for a majority of all dairy cows and oestrus synchronisation with hormones is not allowed. There are reports of declining ability to express oestrus with higher levels of milk production. This makes oestrus detection more difficult. Several aids for oestrus detection have been developed, for instance pedometers and mounting detectors.

Mångkultur i litteratur och i skola : Hur arbetar lärare med barn- och ungdomslitteratursom skildrar mångkultur?

Abstract Our society is becoming increasingly multicultural and so are our schools. This study raises the question of how teachers are working to promote multi-culture and how they can create an understanding of the diversity in the classroom. One way is to use the literature. Literature is already well integrated by many teachers and widely used by pupils. By making use of literature related to multi-culture, pupils can get a deeper understanding of our society.

Eldens hemlighet : om att arbeta med skönlitteratur i andraspråksundervisning

The purpose of this essay is to investigate Swedish as a second language acquisition in a group of students with diverse culturul backgrounds. my intension is to find out if a dialogical posture in teaching with focus on the students earlier knowledge,experianses, thoughts and feelings, will contribute to a teaching enviroment where the students can express them selves and listen to each other. the teachers task is to help the students to explore their own thinking.According to the theoretical base of the essay, sucessfull second language asquisition occours in a meaningsfull context through dialogue and interaction between students and teacher as well as between student and student.I have used a qualitative method consisting in participating as a teacher in this group of second language learners during four lessons, observing, taking notes and writing diary. The teaching material used during the lessons was a book (fiction but based on a true story) and the dialogue in the group proceeded from the story we read together..

Musikklassifikation ? En jämförande studie av de tre generella klassifikationssystemen DDC, SAB och UDC

The purpose of this Master's thesis is to determine which of the three general classification schemes, DDC, SAB, and UDC is the most appropriate for classifying music documents. This is done by analysing and classifying 60 music documents such as recordings, scores and books about music. The codes resulting from the classification are analysed according to a number of evaluation criteria based on classification theory. The criteria focus on the systems specificity, exhaustivity, exclusivity, helpful sequence, hospitality, notation and that related classes are kept together. The study showed that the systems specificity in classification was of great importance in classifying music documents because of the diversity of music genres.

Furthermore; female, outside directors and employee representatives have a positive impact on social performance.

Missuppfattningar inom genetiken: En litteraturstudie om hur missuppfattningar inom genetiken hos h?gstadie- och gymnasieelever kan motverkas

In schools, misconceptions about genetics can arise due to several factors, and the consequences of these misunderstandings can be significant. Lack of education can play a central role in the spread of misinformation about genetics. When teachers lack sufficient knowledge or do not have access to up-to-date resources, they risk inadvertently conveying inaccuracies to students. Additionally, students own preconceived notions and misinterpretations can be reinforced through interaction with their peers, creating a vicious cycle of misinformation. In this study, various misconceptions within genetics education have been identified and analyzed, while different strategies to prevent these misconceptions have been examined. The study revealed that the two most common misconceptions are the confusion between "genes" and "DNA" and the simplified perception of genetic determinism.

Hur fungerar skolbiblioteken? : En kvalitativ intervjustudie om skolbibliotekers och pedagogers syn på litteraturförmedling

This master thesis is aiming to find out how school libraries work towards children in school years 1-6. The mainfocus is how the school librarians and teachers work with literature and reading. The theoretical viewpoints aremainly the sociocultural theory and the child perspective.The study was conducted with participants from five different schools in Uppsala, in the form of qualitativesemi-structured interviews. The results show that schools work with literature first and foremost in a pragmaticway, with reading-strategies and activating discussions. Very little time is spent on reading for its own sake.

Gemensamberedningen av EU:s Maritima Grönbok ur ett Resiliensperspektiv : En studie om den adaptiva kapaciteten i Regeringskansliets inre processer

The study aims to give a description of the conditions in which matters is prepared withinSwedish Government`s offices, to describe the adaptive capacity in the agency`s internalprocesses by investigating the experiences of some civil servants restricted to the Ministry ofEnterprise and the Ministry of Environment in their work with the EU Maritime Policy GreenPaper. The results have been analyzed against the basis of eight identified criteria of buildingadaptive capacity in socially dominated systems. The criteria are comprised of both individualand organizational abilities. Only two of them were fully met; the criteria about diversity inexperiences and knowledge and the criteria about information and how the information hasbeen applied. However, the process has traces of all the identified criteria.
