After narrowly preventing a global pandemic, Mason and his team discover an even deadlier threat has already been set into motion. An unknown adversary has produced enough of a lethal nerve gas to wipe every major city off the face of the world, and their only clue to finding it lies in a cryptic message written in the blood of a man found entombed behind a concrete wall. It isn't until another victim appears - right in the heart of Central Park - that Mason realises the murders are personal in nature, and figuring out the connection between them is the key to averting catastrophe. Eight million lives hang in the balance and their only chance of surviving lies in the hands of Mason, his old friends, and a new partner he's not entirely sure he can trust. Can his team track down a sinister agent codenamed Scarecrow before toxic gas fills the streets of New York City, or will the true power pulling the strings from behind the scenes - the Thirteen - succeed in enacting its genocidal agenda?

Orson Welles directed and starred in this version of Shakespeare's famous tragedy. Filmed on a shoestring budget over two years, Welles strips the famous tale of sexual jealousy and betrayal down to its essentials, casting himself as the tragic Moor. Winner of the 1952 Best Picture Award at Cannes.

Beef cows, particularly as part of seed stock and cow/calf enterprises, are farmed extensively in temperate environments in southern Australia. The fundamental premise of a productive beef enterprise is a calving interval of 365 days. However, production system efficiency can also be determined by comparing inputs, namely megajoules of energy in the form of food, to outputs, namely the number of kilograms of beef sold each year. This thesis examined two heritable and economically desirable traits and the impact that selection to improve these traits had on beef herd productivity - defined in this thesis as Maternal Productivity. Selection for reduced fatness, achieved by selecting animals on the basis of low Rib Fat EBVs, can increase profitability because of consumer demand for lean meat and because sellers of cattle for slaughter are penalised if the carcasses have too much fat on them. Selection for an improvement in feed-efficiency through the trait Net Feed Intake (NFI) can improve profitability because it allows an increase in stocking rates or a reduction in the number of megajoules supplied to the herd for the same level of production.
