Commercial Considerations for Space Resource Utilisation in the Context of Mining Feasibility Studies
Space Resources Utilisation (SRU) is essential for the development of a cislunar economy, helping mitigate the impact of the ‘tyranny of the rocket equation’ by reducing the cargoes and fuel transported out of the Earth’s gravity well. Early activity could be driven by national entities, however …

Determination of Energy Efficiency of Beef Cows under Grazing Conditions Using a Mechanistic Model and the Evaluation of a Slow-Release Urea Product for Finishing Beef Cattle
… the animal. The use of slow-release urea (SRU) products offers a unique opportunity to synchronize ruminal fermentation of carbohydrate with non-protein nitrogen (NPN) release rate. Two experiments were conducted to examine the impact of source, urea or SRU, and level of dietary NPN on 1) …

Degradable intake protein supplementation through the inclusion of urea in finishing diets containing distillers grains: effects on feedlot cattle performance, ruminal fermentation, and feed digestibility
… may arise from the use of slow-release urea (SRU) sources over conventional urea when added to DIP-deficient diets. Therefore, experiments 1 and 2 described in Chapter 3 evaluated the effect of increasing DIP concentration through the inclusion of one of two SRU sources in comparison with the …

Regulation of progesterone receptor expression and activity in uterine cells: Analysis of the molecular actions of estrogens and progestins on the progesterone receptor gene
… of a steroid hormone-responsive unit (SRU). Finally, we examined the ability of ligand-occupied PR to repress ER-mediated transcriptional activity at the gene level as a possible mechanism by which progesterone inhibits $\rm E\sb2$ stimulation of the rat PR gene. In our studies, the …

Investigation of the role of the extracellular β-agarase, produced by the bacterial epiphyte Pseudoalteromonas sp. LS2i, in the virulence response towards the agarophyte Gracilaria gracilis
… In 1993 the Seaweed Research Institute (SRU) found that mariculture of G. gracilis in Saldanha Bay is feasible but that there is potential to improve yields by technical research and development (Anderson et al.1996a). Jaffray and Coyne (1996) developed a pathogenicity assay that …
