Abstract

The results are presented of a process control improvement project at Port Latta, Tasmania, involving process stabilisation and optimisation, improvement in process monitoring and the implementation of early corrective actions when operating variables were outside the target ranges. The main operating variables affecting pellet quality and process performance are the particle size distribution of the concentrate, bentonite consumption rate and heat input. Details are given of the expert system used to monitor the furnace conditions. The benefits obtained from the project included more consistent and improved pellet quality, with the average cold compression strength value of the pellets produced being 16 kg/pellet higher, a reduction in the heat input of 8%, a reduction in bentonite rate of 6%, an increase in the furnace throughput rate of 4% and additional production of 10 000 tonnes per annum through process stabilisation., The results are presented of a process control improvement project at Port Latta, Tasmania, involving process stabilisation and optimisation, improvement in process monitoring and the implementation of early corrective actions when operating variables were outside the target ranges.

Abstract

Skinks represent the most diversified squamate reptiles with a great variation in body size and form, and are found worldwide in a variety of habitats. Their remarkable diversification has been accompanied by only a few chromosome rearrangements, resulting in highly-conservative chromosomal complements of these lizards. In this study cross-species chromosome painting using Scincus scincus (2n = 32) as the source genome, was used to detect the chromosomal rearrangements and homologies between the following skinks: Chalcides chalcides (2n = 28), C. ocellatus (2n = 28), Eumeces schneideri (2n = 32), Lepidothyris fernandi (2n = 30), Mabuya quinquetaeniata (2n = 32). The results of this study confirmed a high degree of chromosome conservation between these species. The main rearrangements in the studied skinks involve chromosomes 3, 5, 6 and 7 of S. scincus. These subtelocentric chromosomes are homologous to the p and q arms of metacentric pair 3 and 4 in C. chalcides, C. ocellatus, L. fernandi, and M. quinquetaeniata, while they are entirely conserved in E. schneideri. Other rearrangements involve S. scincus 11 in L. fernandi and M. quinquetaeniata, supporting the monophyly of Lygosominae, and one of the chromosomes S. scincus 12–16, in M. quinquetaeniata. In conclusion, our data support the monophyly of Scincidae and confirm that Scincus-Eumeces plus Chalcides do not form a monophyletic clade, suggesting that the Scincus-Eumeces clade is basal to other members of this family. This study represents the first time the whole genome of any reptile species has been used for cross-species chromosome painting to assess chromosomal evolution in this group of vertebrates.
