Finns det ett samband mellan ökad mjölkproduktion och mastit?

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Kvinnodominerade och mansdominerade yrken - En studie utifrån icke traditionella yrkesval

In this thesis I am going to study how women experience working in a male-dominated occupation and how men experience working in a female-dominated occupation. I have chosen a qualitative method, interviewing four women and four men. By using this method I have gained a deeper understanding of what it is like having a non-traditional occupation. In the background I have looked into the unequal distribution of power between the sexes as well as the entrance of women on the labour-market, where the law of equality has had a major impact on the strive towards a more equal distribution according to sex. The theoretical part includes different theories where gender is focused, both when it comes to the biological differences as well as the segregation of sexes that prevails in society and here socialization heavily influences the choice of a vocation.

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.

Heteronormativets lag : En rättssociologisk studie av rättsligt homosexuellt föräldraskap

This thesis has focused on the construction of homosexual parenthood in Swedish law and preparatory work. The purpose was to describe the norms about legal parenthood and examine if and how homosexual parenthood was included in the normative parenthood. The study was jurisprudential and based on methods such as sociology with a juridical focus and critical discourse analysis of the juridical texts. The theoretical framework was the critical discourse analysis as well as a queer perspective, both influenced by social constructionism and a poststructional theory. The conclusion of the study is that parenthood is described from what is presumably best for the child, which is two parents of different sexes and biological origin.

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.

Nötkreatur som övernattar på slakteri : effekter på beteende vid drivning och bedövning

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.

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.
