  1. 1. Genetic Studies of Pigmentation in Chicken

    Author : Ulrika Gunnarsson; Leif Andersson; Göran Andersson; Susanne Kerje; William J. Pavan; Uppsala universitet; []
    Keywords : ;

    Abstract : Domestic animals have been selected by humans for thousands of years, which have drastically altered their genetic constitution and phenotypes. In this thesis, several of the most important genes causing pigmentation differences between the wild red junglefowl (Gallus gallus) and domestic chickens have been identified. READ MORE

  2. 2. Beta-glucose 1-phosphate interconverting enzymes in Lactococcus lactis: physiological role and regulation in maltose, trehalose and glucose metabolism

    Abstract : Lactic acid bacteria (LAB), including Lactococcus lactis, are abundant in nature. These bacteria convert carbohydrates into mainly lactate by a rather uncomplicated metabolism. An improved understanding of the physiological and genetical mechanisms involved in carbohydrate metabolism and its regulation will improve the industrial use of LAB. READ MORE

  3. 3. Experimental studies in brain tumours : with special regard to multidrug resistance and the ErbB-family

    Abstract : Primary brain tumours, and especially the most common form malignant gliomas, usually display a pronounced resistance to other treatment modalities when surgery fails to cure. Growth factors, such as EGF and its receptor, frequently amplified and overexpressed in malignant gliomas, and factors associated with multidrug resistance have been suggested to at least partially explain the poor outcome.

  4. 4. The Sacrificial Child in Maori Literature: Narratives of Redemption by Keri Hulme, Patricia Grace, Witi Ihimaera, and Alan Duff

    Author : Ulrika Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : HUMANIORA; HUMANITIES; Maori fiction; childhood studies; Keri Hulme; Patricia Grace; Witi Ihimaera; Alan Duff; sacrificial child; children in literature;

    Abstract : This study is an examination of the theme of the sacrificial child in four of the most well-known novels by Maori authors published in the 1980s and 1990s: Keri Hulme’s The Bone People (1983), Patricia Grace’s Potiki (1986), Witi Ihimaera’s The Whale Rider (1987), and Alan Duff’s Once Were Warriors (1990). The motif of a special child whose death is the pivotal event of the narrative functions partly as a symbol of the destructive marginalization of the Maori people in colonial and postcolonial New Zealand, but it is also given a redemptive significance in that, in all the novels, the child’s death has the effect of healing and strengthening its community or family.

    Abstract : The Nigerian city of Jos used to be seen as a peaceful place, but in 2001 it was struck by clashes that arose from what was largely understood as issues of ethnic and religious belonging. The event, which would become known as ‘the crisis’, was experienced as a rupture and a loss of what the city had once been, and as the starting point of a spiral of violence that has continued up to today.
