(S)-1,4,7-tris(2-hydroxypropyl)-1,4,7,10-tetraazacyclododecane
(2006)The title compound, C17H38N4O3, is an asymmetric tetraazacyclododecane macrocycle with three pendant hydroxyisopropyl arms. Two of these arms are involved in hydrogen bonding internal to the macrocyclic ring while the third ... -
(S)-4-(4-Hydroxyphenyl)-2,2,4-trimethylchroman
(2005)The enantiomerically pure title compound, C18H 20O2, crystallizes with one molecule in the asymmetric unit. The packing arrangement is significantly different from that of its racemate. Linear hydrogen-bonded chains are ... -
(S)-4-(4-Mercaptophen-yl)-2,2,4-tri-methyl-chroman
(2007)Crystallization of the title compound, C18H20OS, from cyclo-hexane gives the unsolvated crystal structure. Linear strands of mol-ecules are formed by S - H⋯O hydrogen bonds, with edge-to-face π-π inter-actions connecting ... -
(S)-O-[4-(2,2,4-trimethylchroman-4-yl)phenyl] N,N-dimethylthiocarbamate
(2007)Crystallization of the (S)-enanti-omer of the title compound, C21H26NO2S, from methanol gave an unsolvated crystal structure in which one-dimensional strands of mol-ecules are formed through a series of C - H⋯O and C - H⋯S ... -
S-[4-(2,2,4-trimethylchroman-4-yl)phenyl] N,N-dimethylthiocarbamate
(2006)Unlike the previously reported structure of the isomer O-[4-(2,2,4-trimethylchroman-4-yl)phenyl] N,N-dimethylthiocarbamate [de Vries, Bredenkamp, Jacobs & Lloyd (2005). Acta Cryst. E61, o2871-o2872], which packs in ... -
S-band monopulse radar receiver design and implementation
(Stellenbosch : University of Stellenbosch, 2006-03)This thesis documents the design and implementation of an S-band receiver for phasecomparison monopulse radar. The design and evaluation of the various sub-systems involved in realizing the receiver are discussed in ... -
S-parameter measurements yielding the characteristic matrices of MTLs
(1998)A frequency domain method is presented which yields accurate characteristic matrices of uniform multiconductor transmission lines (MTLs). It uses simple two-port network analyzer S-parameter measurements of a set of ... -
S-type ignimbrites with polybaric crystallisation histories: the Tolmie Igneous Complex, Central Victoria, Australia
(2011)The Late Devonian Tolmie Igneous Complex (in north-eastern Victoria, Australia) contains S-type, intracaldera, rhyolitic ignimbrites with multiple generations of phenocrysts of biotite, garnet, cordierite and orthopyroxene; ... -
SA children take a sun-step to engineering
(1999)The MTN-SUNSTEP programme reaches out to disadvantaged children and increases their science, electronics and technology awareness. It also reinforces the fact that electronics offer career opportunities and that mathematics ... -
A SA study into the adherence to the International Labour Organisation's Code of Practice on HIV/AIDS and the world of work in HIV/AIDS workplace policy content development
(Stellenbosch : Stellenbosch University, 2004-12)ENGLISH ABSTRACT: In this study, existing data were used to conduct a descriptive research study into the adherence or lack thereof - in varying degrees - of South African companies to the ten key principles of the ...
