1. 1. Essential conserved active site residues in class Ia ribonucleotide reductase from Escherichia coli : identification of radical reaction intermediates and radical transfer intermediates

   Författare :Annika Persson; Marc Fontecave; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Biology; molekylärbiologi;

   Sammanfattning : The enzyme ribonucleotide reductase catalyzes the reduction of ribonucleotides to the corresponding deoxyribonucleotides, the building blocks of DNA. The class Ia enzyme from Escherichia coli consists of two homodimeric subunits denoted protein R1 and protein R2, each inactive alone. LÄS MER

3. 2. När förskolan möter neurovetenskap : Kunskapsteoretiska möten i teori och i praktik

   Författare :Lena Aronsson; Hillevi Lenz Taguchi; Annika Andersson; Sven Persson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neuroeducation; educational neuroscience; Swedish preschool; early childhood education; cartographic mapping; neuropedagogik; pedagogisk neurovetenskap; svensk förskola; förskoledidaktik; kartografiskt spårande; Early Childhood Education; förskoledidaktik;

   Sammanfattning : This doctoral thesis in Early Childhood Education reports on encounters between the theories and practices of Swedish preschool and research-based neuroscience knowledge. Thus, this thesis concerns epistemological encounters and didactic consequences. LÄS MER

4. 3. Modelling and simulation of building components : thermal interaction between multilayer wall and hydronic radiator

   Författare :Christian Brembilla; Thomas Olofsson; Per Sahlin; Persson Leif; Annika Moström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; systemanalys; Systems Analysis; engineering science with specialization in microsystems technology; teknisk fysik med inriktningen mikrosystemteknik;

   Sammanfattning : Background and Scope: The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. LÄS MER

5. 4. Tvångsvård av gravida missbrukare till skydd för fostret

   Författare :Jeanna Hoffmann; Kerstin Nordlöf; Annina H. Persson; Laura Ervo; Annika Rejmer; Örebro universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pregnancy; Substance Use; Coercive Care; Foetus; Legal Subject; Legal History;

   Sammanfattning : Researchers have pointed out the association between exposure to alcohol during pregnancy and damage to the foetus. The offspring show an increased perinatal mortality and morbidity rate. Other substances may also cause foetal damage but without any typical adverse effects. LÄS MER

7. 5. Neonatal Mortality in Vietnam : Challenges and Effects of a Community-Based Participatory Intervention

   Författare :Nguyen Thu Nga; Lars-Åke Persson; Uwe Ewald; Annika Johansson; David Osrin; Uppsala universitet; []
   Nyckelord :Facilitation; Local stakeholder group; Maternal-and-Newborn Health Group; Neonatal mortality; Primary health care; Vietnam; International Health; Internationell hälsa;

   Sammanfattning : Globally neonatal mortality accounts for 40% of under-five deaths. Participatory interventions where the local problems are addressed have been successful in some settings. LÄS MER
