Draining under gravity in steel galvanization.
No full textThe problem of the coating of steel has been considered in several Mathematics in Industry study groups. In this process, after passing through a bath of molten alloy, steel sheeting is drawn upward to allow draining under gravity and stripping using an air knife, leaving a coating of desirable thickness. Here we discuss some aspects of the problem and in particular the gravity draining component. The problem is a very nice introduction to industrial modelling for students, but is also relevant for manufacturing.

Facilities, breed and experience affect ease of sheep handling: the livestock transporter's perspective
No full textPublished online: 15 April 2015An understanding of the perceived importance of a variety of factors affecting the ease of handling of sheep and the interactions between these factors is valuable in improving profitability and welfare of the livestock. Many factors may contribute to animal behaviour during handling, and traditionally these factors have been assessed in isolation under experimental conditions. A human social component to this phenomenon also exists. The aim of this study was to gain a deeper understanding of the importance of a variety of factors affecting ease of handling, and the interactions between these from the perspective of the livestock transporter. Qualitative interviews were used to investigate the factors affecting sheep behaviour during handling. Interview transcripts underwent thematic analysis. Livestock transporters discussed the effects of attitudes and behaviours towards sheep, helpers, facilities, distractions, environment, dogs and a variety of sheep factors including breed, preparation, experience and sex on sheep behaviour during handling. Transporters demonstrated care and empathy and stated that patience and experience were key factors determining how a person might deal with difficult sheep. Livestock transporters strongly believed facilities (ramps and yards) had the greatest impact, followed by sheep experience (naivety of the sheep to handling and transport) and breed. Transporters also discussed the effects of distractions, time of day, weather, dogs, other people, sheep preparation, body condition and sheep sex on ease of handling. The concept of individual sheep temperament was indirectly expressed.C. L. Burnard, W. S. Pitchford, J. E. Hocking Edwards and S. J. Haze
Genetics of lamb survival: Preliminary studies of the information nucleus flock
No full textPoor lamb survival is recognised in Australia as a major contributor to reproductive inefficiency in the national flock. This paper provides preliminary estimates of phenotypic and genetic parameters on lamb survival and related traits for the 2007 and 2008 data from the CRC for Sheep Industry Innovation’s Information Nucleus. The paper focuses on the potential utility of measurements on related traits for achieving genetic improvement in lamb survival. Although timed lamb behaviour traits show consistently high genetic correlations with lamb survival to 3 days of age, no obvious candidates have yet been identified for commercial use as indicator traits to genetically improve lamb survival.F.

Russell–Silver syndrome presenting as early asymmetric IUGR
No full textWe report a case of severe intrauterine growth restriction (IUGR) which was diagnosed as Russell–Silver syndrome (RSS) postnatally. RSS (also known as Silver–Russell syndrome) is one of more than 300 recognised forms of genetic disorder that leads to short stature. Uniparental disomy for chromosome 7 (UPD7), i.e. inheriting two copies of chromosome 7 from the mother, and a change in methylation pattern (biochemical silencing of gene expression) of chromosome 11 are the most frequently associated chromosomal defects. A wide spectrum of appearances and symptoms are associated with the condition. Most characteristics are not easily identifiable with prenatal diagnostic ultrasound. The symptom most likely to be detected sonographically is IUGR. This case seeks to raise awareness of RSS, and encourages clinicians to consider uncommon genetic disorders such as RSS as a possible cause of early asymmetric IUGR.
