Many scientists agree that phytoestrogens could have an effect on the reproduction of an animal. The question is now why and what mechanisms that play an important role. This paper has been focusing on the estrus behavior of gilts by use of a behavioral study. Some of the gilts were given additional feed with the phytoestrogen genistein which commonly occurs in the feed as a part of soybean products. Blood samples were collected and analyzed for progesterone and estradiol concentrations.

This project is a literature study with the hypothesis that Arctic climate has a positive effect on the accumulation of metabolites in berries. Plant metabolites are often divided into primary and secondary metabolites. Primary metabolites such as proteins and nucleic acids are essential for cell function, while secondary metabolites are often non-essential, but have important functions regarding reproduction and survival. The berries mentioned in this project are from the families Ericaceae, Rosaceae, Elaeagnaceae och Grossulariaceae.The conclusion drawn from this literature study is that it is not obvious what favours accumulation of metabolites in berries. Other factors aside from climate affect the production of secondary metabolites, such as time of harvest, cultivars and ripeness.

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

In the year of 1935 Sweden started to apply the practice of their first sterilizing laws. In this thesis 2 sterilizing laws are considered. The laws regulated those individuals who were not considered appropriate for reproduction. The sterilizing laws themselves are based on several large investigative studies on how to evaluate and categorize different individuals.  The purpose of my thesis is to examine through a literature study how these individuals considered for sterilization were valued and how social problems were created to fit the character features of these people. I also look at how sterilization became an acceptable method to deal with these constructed social problems. The materials I have studied include 3 pre-studies and the 2 laws about sterilization which were the result of these pre-studies.  I found that the motives behind the sterilizations were social, economical and genomic hygienical.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

C-uppsats vars huvudsyfte var att undersöka hur stor igenkänning människor har av företagsmärken utan att logotypen finns med. Genom att arbeta med både en kvalitativ och kvantitativ metod har vi fått fram våra resultat, detta genom att våra respondenter besvarade en enkät. Våra teoretiska perspektiv kommer från en blandning av olika ämnesområden, så som psykologi och informationsdesign med fördjupningar i bland annat perception, objektsigenkänning, symbolik och färgers betydelse. Genom våra undersökningar kom vi fram till att det inte finns något enkelt svar på huruvida märken känns igen eller inte. Bland våra utvalda märken var könsbundenheten låg, och ålder har viss betydelse för igenkänningen.

Denna uppsats undersöker hur kvinnor och män i olika åldersgrupper förhåller sig till Flashapplikationer utifrån deras uppfattning om färg och form. Deltagarna som består av skolungdomar, nyexaminerade studenter och pensionärer har genom en enkät och en semistrukturerad intervjuform fått redogöra för sina intryck av Santa Marias, Eccos och Indiskas webbplatser. Undersökningsdeltagarna identifierar Flashelementen genom deras rörelser. Deltagarna vill välja om de ska se animationer och andra applikationer skapade i Flash för att inte tappa koncentrationen från övrigt innehåll. Studenterna i undersökningen har en mer kritisk hållning till färgval, formgivning och användandet av Flash än övriga.

Syftet med denna litteraturstudie är att beskriva fåglarnas reproduktion och hur den skiljer sig från däggdjurens. I studien har störst vikt lagts på värphöns men många aspekter som beskrivs gäller även för vilda fåglar. Reproduktionen beskrivs översiktligt för både värphöna och tupp. Reproduktionsorganen beskrivs anatomiskt, fysiologiskt och histologiskt samt en del om det endokrina systemet och dess påverkan på hönsens reproduktion ingår också. I uppsatsen beskrivs även hur ljuset kan påverka framförallt hönans äggläggningscykel. Slutsatsen av denna litteraturstudie är att fåglarnas reproduktionsorgan ser annorlunda ut och har flera funktioner som inte är analoga med däggdjurens, men det finns också vissa likheter.

The aim of this study is to illuminate social worker?s perception of social class within the Swedish social service system. This study therefor examine if social class contributes to the production and reproduction of the client and what impact social class has on the interaction between client and social workers. The study was conducted with qualitative semi-structured interviews with social workers from three different departments of social service. The theoretical approach is Yeheskel Hasenfeld?s theory about moral practices in welfare organisations, Michael Lipsky and Roine Johansson?s theories about client construction and Pierre Bourdieu?s class theory.

Det finns stereotyper om kvinnor med olika hårfärg och stereotyper påverkar människors empati och bedömning. Därför gjordes ett kvasiexperiment där det undersöktes om en kvinnlig brottsling väcker olika mycket empati beroende på (a) vilken hårfärg hon har och (b) empatisörens kön. I studien deltog 132 personer, varav 61 kvinnor och designen var en enkät där experimentgruppen fick läsa om en gärningskvinna som antingen var blond, brunhårig, svarthårig eller rödhårig och därefter skatta empati utifrån Batsons empatiskala. Resultaten visade att (a) blondiner väcker minst empati medan rödhåriga väcker mest (b) kvinnor  känner högre empati än män och (c) empati stiger med åldern. Dessa resultat förklarades bland annat med att blondiner mer än rödhåriga ses som objekt i samhället och är därför mindre empativäckande, att kvinnor i högre grad än män förväntas vara empatiska då det är detta beteende som förväntas av kvinnorollen samt att empati är något som utvecklas med tiden..

The thesis aims to increase our understanding about parents reasoning about the elementary school choice by studying which factors parents perceive as important during the decision making process and also by giving meaning to Pierre Bourdieu?s concept of capital through the parents perspective. The empirical material comes from seven BNIM-interviews made with parents, which has been analyzed according to the thematic field analysis.The results show that the parents are not especially concerned about making an active school choice. Stability, closeness, friends, rumors, development and adaptability to the reality are the factors that are perceived as the most important in the decision making process. The school choice has a limited meaning as an investment in social capital, from Bourdieu?s perspective.

The purpose of this study is to identify and make attitudes among social workers towards homosexual and bisexual people visible, examine how these attitudes relate to their actions in their professional role and how these attitudes and actions can be understood by theories of heteronormativity and power. The study is a cross-sectional quantitative survey in the form of a questionnaire completed by social workers. The result shows that there are two groups among the social workers. One larger group that reproduces a norm of acceptance toward homosexual and bisexual people and one smaller that reproduces a heterosexual norm. This reproduction of heteronormativity increases the risk for homosexual and bisexual people to be made invisible and treated more negatively in contact with social workers, which in turn can lead to worse health among the clients..

This essay tries to show how The Swedish Museum of Architecture, Stockholm, with the exibition Architecture in Sweden - Function, Design and Aesthetic through the Ages, presents and represents architecture. It is stated that this is done in a multi-perspectival, multimedial fashion, with the aid of, for example, photography, models and mixed material surrounding the wide concept of ?architecture?. One chapter discusses the relationships between the exhibition on site, the exhibition catalog and the museum´s website. Another chapter argues that there can be no essential or perfect representation of architecture, although this utopian wish most certainly exists even today.

Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.
