An appraisal of the applicability of development journalism in the context of public service broadcasting (PSB) This paper was presented during the South African Broadcasting Corporation's ‘News Content Planning’ workshop on 21 October 2006, held at the Birchwood Executive Hotel, in Boksburg, South Africa.
A synchrotron radiation study of the one-dimensional complex of sodium with (1S)-N-carboxylÂato-1-(9-deazaÂadenin-9-yl)-1,4-dideÂoxy-1,4-imino-d-ribitol, a member of the ’immucillin’ family
The sodium salt of [immucillin-A–CO2H]− (Imm-A), namely catena-poly[[[triaquaÂdisodium(I)](μ-aqua)[μ-(1S)-N-carÂboxÂylÂato-1-(9-deazaÂadenin-9-yl)-1,4-dideÂoxy-1,4-imino-d-ribiÂtol][triaquaÂdisodium(I)][μ-(1S)-N-carboxylÂato-1-(9-deazaÂadenÂin-9-yl)-1,4-dideÂoxy-1,4-imino-d-ribitol]] tetraÂhydrate], {[Na2(C12H13N4O6)2(H2O)7]·4H2O}n, (I), forms a polymeric chain via Na+—O interÂactions involving the carboxylÂate and keto O atoms of two independent Imm-A molÂecules. Extensive N,O—H⋯O hydrogen bonding utilizing all water H atoms, including four waters of crystallization, provides crystal packing. The structural definition of this novel compound was made possible through the use of synchrotron radiation utilizing a minute fragment (volume ∼2.4 × 10−5 mm−3) on a beamline optimized for protein data collection. A summary of intra-ring conformations for immucillin structures indicates considerable flexibility while retaining similar intra-ring orientations
