  1. 16. On treatment and prognosis in epidermoid anal cancer

    Författare :Per J Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epidermoid anal cancer is an uncommon, malignant disease that is diagnosed in approximately 100 patients annually in Sweden. The incidence is increasing worldwide. Over the past 30 years, a dramatic change in the therapeutic approach has occurred leading to non-surgical treatment with radiotherapy and chemotherapy being primary options. LÄS MER

  3. 17. Allosteric Regulation of mRNA Metabolism : -Mechanisms of Cap-Dependent Regulation of Poly(A)-specific Ribonuclease (PARN)

    Författare :Per Nilsson; Anders Virtanen; Megerditch Kiledjian; Uppsala universitet; []
    Nyckelord :Cell and molecular biology; mRNA degradation; deadenylation; cap; poly A ; PARN; allosteric regulation; Cell- och molekylärbiologi;

    Sammanfattning : Degradation of mRNA is a highly regulated step important for proper gene expression. Degradation of eukaryotic mRNA is initiated by shortening of the 3’ end located poly(A) tail. Poly(A)-specific ribonuclease (PARN) is an oligomeric enzyme that degrades the poly(A) tail with high processivity. LÄS MER

  4. 18. Brukade bilder : Södra Skandinaviens hällristningar ur ett historiebruksperspektiv

    Författare :Per Nilsson; Mats Burström; Anders Carlsson; Anders Gustafsson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Rock art; South Scandinavian Bronze Age; Iron Age; Uses of the Past; Hällristningar; hällbilder; bronsålder; järnålder; historiebruk; arkeologi; Archaeology;

    Sammanfattning : The timeframe of the south Scandinavian rock art tradition extends from c.1700/1600 to 300 /200 BC. The chronological boundaries of the rock art phenomenon thereby coincide roughly with the timeframe of the Nordic Bronze Age, and rock art figures have come to be understood and interpreted as a Bronze Age phenomenon.

  5. 19. Exploring Probabilistic Reasoning : A Study of How Students Contextualise Compound Chance Encounters in Explorative Settings

    Författare :Per Nilsson; Inger Wistedt; Lennart Hellström; Dave Pratt; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Probabilistic reasoning; randomness; compound chance encounters; contextualisation; differentiation; elaborative variation.; MATHEMATICS; MATEMATIK; Matematikdidaktik; Mathematical Education;

    Sammanfattning : This thesis aims at exploring how probabilistic reasoning arises in explorative learning situations that are random in nature. The focus is especially on what learners with scant experience of formal theories of probability do and can do when dealing with compound random situations in which they are offered opportunities to integrate different probabilistic lines of reasoning.

  7. 20. Naturen, vetenskapen och förnuftet : upplysningens dialektik och det andra moderna

    Författare :Per Nilsson; Gunnar Andersson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Modernity; enlightenment; postmodernism; instrumental rationality; value rationality; communicative rationality; discourse ethics; truth; fallibilism; claims to Tightness; revisability; von Wright; Adorno; Horkheimer; Marcuse; Apel; Habermas; Popper; Foucault;

    Sammanfattning : The topic of this study is one specific area where the tension between instrumental rationality and value rationality becomes prominent: the question whether we have a rational responsibility for nature or not. Such a responsibility cannot be derived from instrumental reason, but it is argued that it can be derived from discourse ethics and communicative rationality. LÄS MER
