Valg af DM (AC) tillidsrepræsentant for Kemisk Institut Der er indkaldt til det store toårige møde for medlemmer af Dansk Magisterforening, lokalklub 9 for NF og SUN torsdag den 3. december, hvor der bl.a. skal indrapporteres eller stemmes for Kemisk Instituts TR for VIP, AC-TAP og Ph.D.-stipendiater på del B. I forberedelse til dette møde indkalder jeg hermed til et lokalt møde i KI, hvor jeg ser frem til at vi vælger en tillidsrepræsentant. Jeg er ikke til genvalg da jeg skal gå på pension fra den 1.1.2010. Niels Pind har været suppleant. Mødet finder sted torsdag den 26.11.2009 kl. 15:15 i Aud. VI. Alle VIP osv er velkomne, om de er medlem af DM (AC) eller ej. Dagsorden for mødet: 1. Valg af tillidsrepræsentant 2. eventuelt. Mvh Dieter Britz 1
Reaxys kursus på Statsbiblioteket Elsevier, som står bag databasen, tilbyder nu et kursus i brugen af Reaxys Kursusindhold: A very short introduction to which journals/literature is searched; a little bit about searching physical/chemical properties of organic molecules and most about fragment based synthesis planning: how is a given functionality converted into another functionality and which protocol do I need to use for a third functionality remains stable during the reaction (the use of free sites and generic groups etc). Included real examples. Tid: Tirsdag d. 15.12.2009 kl. 9.00-10.30 Sted: M1 på Statsbiblioteket (indgang ved siden af informationen i forhallen) Tilmelding til: Marianne Vadgaard Christensen på mvc@statsbiblioteket.dk senest d. 11.12.2009 Max. deltagerantal: 40 English: Elsevier will give a short introduction to Reaxys at The State and University Library. 15. December 2009 9.00-10.30 am Room M1 (next to the Information in the Hall) Sign up: Marianne Vadgaard Christensen at mvc@statsbiblioteket.dk 11. December 2009 at the latest.
inano lecture of the week - open to all Professor Bengt Nordén Chemistry and Bioscience Department Chalmers University of Technology Gothenburg, Sweden Title: Use of polarized light (linear dichroism) for studying structure of biomacromolecules, in solution at membranes and in complexes Time: Friday 27 November 2009, at 10:15-11:00. Coffee and bread will be served from 10:00 Location: Auditorium 3 rd floor, Dept. of Physics Abstract: Polarized-light (linear dichroism) spectroscopy is useful for studying structure in systems that cannot be studied the normal way, such as with x-ray crystallography or NMR. A recent example is a study of a fibrous protein-dna complex that cannot be crystallized but which is easy to align by flow in solution: To get mechanistic insight into the DNA strandexchange reaction of homologous recombination we studied a filament structure of a human Rad51 protein, combining molecular modeling with experimental data. We build our structure on reported structures for central and N-terminal parts of pure (uncomplexed) Rad51 protein with Site-Specific Linear Dichroism (SSLD) data on Rad51-dsDNA filaments in solution axis [1]. SSLD spectroscopy is based on molecular replacement of individual aromatic residues in the protein with other aromatic residues providing angular orientations of the replaced residues relative to the filament axis. An outlook will be given on some new applications of LD spectroscopy for studying peptide and protein structure in lipid vesicle model membranes, to follow slow structural rearrangements and to study recognition of DNA sequence by a softness mechanism. 1.

inano lecture of the week - open to all Professor Ian Richardson School of Civil Engineering University of Leeds Leeds, United Kingdom Title: A Close Look at the Built Environments Glue Time: Friday 11 December 2009, at 10:15-11:00. Coffee and bread will be served from 10:00 Location: Auditorium 3 rd floor, Department of Physics Abstract: Consider for a moment the materials in the structures around you: in the buildings, roads, bridges, dams, tunnels, etc. There is a lot of cement. In fact, the quantity of Portland cement used is enormous, with annual world production rapidly approaching three billion tonnes. The volume of concrete produced by mixing cement with aggregates and water is truly vast: about one cubic metre for every person in the world, every year! The material that binds all this concrete together is clearly important stuff; but what is it? A number of solid products are formed when the cement reacts with water, some of which are crystalline and so easily identified. But the main binding phase is nearly amorphous, highly variable in chemical composition, nanostructure and morphology, and it is mixed on a very fine scale with microcrystals of other phases; establishing its exact nature has consequently proved somewhat difficult. To add further complication, the Portland cement in concrete is now often partially replaced with various mineral admixtures, which results in significant changes. In this lecture, a detailed account of the nature of the binding phase will be presented for a range of cements
