Feed channel spacer characteristics and their optimisation
… refers to the optimization of feed channel spacers, which is investigated in this thesis. The feed channel spacers serve to improve the mass transfer by promoting turbulence and provide passage for the fluid. However, the presence of spacers also significantly increases the channel pressure …

Genetic variation of the ribosomal DNA intergenic spacer of maize
… variation in the ribosomal DNA (rDNA) intergenic spacer (IGS) at initial and advanced cycles of selection. RSSSC and RBS10 underwent reciprocal recurrent selection with an inbred tester in a high yield environment, whereas BS10 and BS11 were subjected to full-sib reciprocal recurrent selection. …

Phylogenetic Analysis of Iliamna (Malvaceae) Using the Internal Transcribed Spacer Region
… using sequences from the internal transcribed spacer region (ITS) of the nuclear ribosomal RNA genes in order to determine its biogeographical and evolutionary history. Cladistic analysis was performed and the resulting phylogeny is presented. The ITS data provide new insights in the …

The behaviour of liquid movement in three dimensional weft knitted spacer fabrics
… (launderability) could be beneficial. 3D knitted spacer fabrics can afford a range of properties including an open structure to allow moisture and heat to be expelled, particularly for use against the skin for medical applications. Due to their flexible nature and compression resisting properties …

PAIRING FASCIOTOMY AND SILICONE SPACER INSERTION WITH A RAT MODEL OF COMPARTMENT SYNDROME
… surgery (n=10) . A number of rats had a silicone spacer inserted at the fasciotomy site and left in for either 3 (n=24) or 6 (n=12) days. Functional and histological data from these groups were analyzed. No changes were found in functional data from the fasciotomy or silicone spacer groups at 7 or …

A synopsis of the genus Octopoma N.E.Br. (Ruschioideae) using morphology, 5S NTS and psbA - trnH spacer regions
The genus Octopoma N. Br. is nested within the Ruschioideae in Aizoaceae. It has been thought that eight species make up the genus. The classification was based mainly on the possession of eight locules. This study was, therefore, undertaken to test the monophyly of the genus, and to draw up new …
