2. 11. Evolving the Methodology for Detection of Primary DNA Damage : Development, adaptation and assessment of the single cell gel electrophoresis (comet) assay

   Author : Erik Bivehed; Björn Hellman; Hanna Karlsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Comet assay; DNA damage; DNA strand breaks; Flash-comet; Genotoxicity; In vitro; Single cell gel electrophoresis; Polymerase assisted DNA damage assay PADDA ; TK6 cells; UCDAS; U937 cells; Toxikologi; Toxicology; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : Deoxyribonucleic acid (DNA) is one of the most important molecules in nature. It is the fundamental carrier of evolutionary information and constitutes the genetic blueprint of all living organisms. Being the sole source of information, it is vital for the cell to transmit the correct genetic information from generation to generation. READ MORE

4. 12. Solution-Chemically Derived Spectrally Selective Solar Absorbers : With System Perspectives on Solar Heating

   Author : Tobias Boström; Ewa Wäckelgård; Gunnar Westin; Björn Karlsson; Peter Lund; Uppsala universitet; []
   Keywords : Materials science; solar; thermal; absorber; selective; chemical; Materialvetenskap;

   Abstract : This thesis consists of two parts, one dominating part concerning spectrally selective solar absorbers and one dealing with thermal solar systems. The appended papers I to VIII concern the solar absorber part, papers dealing with the systems part have not been included in the thesis. READ MORE

5. 13. Optical Efficiency of Low-Concentrating Solar Energy Systems with Parabolic Reflectors

   Author : Maria Brogren; Arne Roos; Björn Karlsson; Andreas Häberle; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Photovoltaic cells; Photovoltaic-thermal systems; Parabolic reflectors; Optical properties; Reflector materials; Optical efficiency; Accelerated ageing; Outdoor ageing; Building-integrated photovoltaics; Teknisk fysik; Engineering physics; Teknisk fysik;

   Abstract : Solar electricity is a promising energy technology for the future, and by using reflectors for concentrating solar radiation onto photovoltaic cells, the cost per produced kWh can be significantly reduced. The optical efficiency of a concentrating system determines the fraction of the incident energy that is transferred to the cells and depends on the optical properties of the system components.

6. 14. An analysis of the relationship between the energy and buildings sectors in Sweden

   Author : Mehmet Börühan Bulut; Björn Karlsson; Peter Stigson; Fredrik Wallin; Eriksson Ola Norrman; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy sector; buildings sector; energy efficiency; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Climate change is one of the global challenges of our time. The energy sector is at the focus of the European efforts to combat climate change as it accounts for 80% of the total greenhouse gas emissions in the European Union. READ MORE

7. 15. Building as active elements of energy systems

   Author : Mehmet Börühan Bulut; Björn Karlsson; Fredrik Wallin; Peter Stigson; Jenny Palm; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart grid; smart home; cooperation; energy; buildings; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Buildings account for approximately 40% of the energy demand and 33% of the total greenhouse gas emissions in the European Union. Accordingly, there are several efforts that target energy efficiency in buildings both at the European and Swedish levels. The role of buildings in climate change mitigation, however, is not limited to energy savings. READ MORE
