1. 1. Molecular Insights into Kcnq1ot1 Noncoding Antisense RNA Mediated Long Range Transcriptional Gene Silencing

   Författare :Radha Raman Pandey; Chandrasekhar Kanduri; Karl Ekwall; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epigenetics; gene silencing; noncoding RNA; genomic imprinting; Kcnq1ot1; Medical genetics; Medicinsk genetik;

   Sammanfattning : Non-coding antisense RNAs have been implicated in the epigenetic silencing of individual gene as well as chromosomal domains. While silencing of the overlapping gene by antisense RNAs has been well investigated, their functional role in silencing of chromosomal domains remains enigmatic. LÄS MER

3. 2. Engineering and detecting microwave photons

   Författare :Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microwave photon detection; Quantum optics; open quantum systems.; tunable cavity; cross-Kerr effect; circuit QED;

   Sammanfattning : Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. LÄS MER

4. 3. Quantum optics in superconducting circuits : Generating, engineering and detecting microwave photons

   Författare :Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; single photon source; superconducting circuits; single photon detector; cross-Kerr effect; Quantum optics; circuit QED;

   Sammanfattning : Quantum optics in superconducting circuits, known as circuit QED, studies the interaction of photons at microwave frequencies with artificial atoms made of Josephson junctions. Although quite young, remarkable progress has been made in this field over the past decade, especially given the interest in building a quantum computer using superconducting circuits. LÄS MER

5. 4. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

   Författare :Mina Larsson; Jan Lindgren; Jean-Claude Lassègues; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; Chemistry; Kemi;

   Sammanfattning : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. LÄS MER

7. 5. Mathematics in the Swedish Upper Secondary School Electricity Program : A study of teacher knowledge

   Författare :Lena Aretorn; Manya Raman Sundström; Tomas Bergqvist; Ola Helenius; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; teacher knowledge; electricity education; upper secondary school; vocational education; Swedish secondary school; didactics of mathematics; matematikdidaktik;

   Sammanfattning : Mathematical knowledge is often a prerequisite for students at Swedish upper secondary vocational programs to be able to study vocational courses, for example electricity courses in the Electricity Program. Electricity Program students study mathematics in their electricity courses as well as in their mathematics course. LÄS MER
