   Sammanfattning : Normative assumptions regarding reciprocity between adult children and elderly parents continue to dominate narratives on later life in sub-Saharan Africa. Yet strenuous socioeconomic conditions make it difficult for families to meet expectations of care and support. LÄS MER

4. 23. Effectiveness and Evaluation of Wood Protection against Biological Deterioration Caused by Filamentous Fungi

   Författare :Olena Myronycheva; Olov Karlsson; Lone Ross; Luleå tekniska universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

   Sammanfattning : Developing a holistic understanding of the biological deterioration of wooden material by fungi in the laboratory and outdoor conditions requires the development of new assessment procedures and tools that allow describing the process with maximum precision and accuracy. Environmental biodeterioration is a complex process including a combination of physical, chemical and biological changes, with many uncertainties limiting the predictability and effectiveness of selected preservatives after laboratory tests.

5. 24. Accumulative Charge Separation in Photocatalysis : From Molecules to Nanoparticles

   Författare :Mariia Pavliuk; Jacinto Sá; Leif Hammarström; Gary Brudvig; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Accumulative charge separation; Electron transfer; Plasmon dynamics; Time-resolved spectroscopy; Photocatalysis.; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Sammanfattning : Photochemical energy conversion into solar fuel involves steps of light absorption, charge separation and catalysis. Nature has taught us that the effective accumulation of redox equivalents and charge separation are the key steps in sunlight conversion. LÄS MER

7. 25. Climate Science for Policy? The knowledge politics of the IPCC after Copenhagen

   Författare :Jasmine Livingston; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; science; politics; IPCC; knowledge; performance;

   Sammanfattning : The rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. LÄS MER
