A significant fraction of the stellar population in the cusps around central black holes of galaxies consists of compact remnants of evolved stars, such as white dwarfs, neutron stars and stellar… (More)
Several economical methods for geometry optimisation, applicable to larger molecules, have been evaluated for phosphorus acid derivatives. MP2/cc-pVDZ and B3LYP/6-31+G(d) geometry optimizations are… (More)
A large-scale armed conflict between Hezbollah and Israel in July 2006 caused the evacuation of a large number of Swedish residents from Lebanon. This report describes the evacuation throughout its… (More)
Structural studies were performed on synthetic oligonucleotides with sequences corresponding to the P4/P6 and J3/4, J6/7 regions of the self-splicing group I intron of the bacteriophage T4 nrdB… (More)
Repeat sequences are associated with several human diseases, such as Friedreich’s ataxia, polycystic kidney disease and cancer. These sequences can form non-B-DNA structures, including triplex… (More)
A kinetic study on the reactions of pivaloyl chloride with a nucleoside H-phosphonate (bisacylphosphite formation), or a protected nucleoside with a free 5'-OH (5'-O-pivaloylation) has been carried… (More)
Abstract An improved version of the H-phosphonate approach to RNA-synthesis is presented and the studies that led to alterations in the protecting group strategy are discussed.
Several economical methods for geometry optimization, that should be applicable to larger molecules, have been evaluated for 19 phosphorus acid derivatives. MP2/cc-pVDZ geometry optimizations are… (More)
Abstract In the final stages of automated oligonucleotide synthesis the oligomer has to be cleaved from the solid support. This is usually carried out using ammonolysis since the 3′-end of the… (More)
