The Dating of Rock Art: a Critique

The methods for estimating the antiquity of rock art are reviewed critically, dividing them into traditional and scientific approaches. The reliability of both is examined critically. It seems that the most promising options have attracted only limited interest, while those methods that have been afforded the most sustained research efforts have been discredited or provide only tenuous results....

Recent revisions of phosphate rock reserves and resources: a critique

Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted. Recently, global PR reserves as reported by the US Geolog...

Lester Workshop

Superfi cial scald of apples and pears, which manifests as brown or black patches on the fruit skin, results from necrosis of the hypodermal cortical tissue (Bain and Mercer, 1963) and is thought to be induced by oxidation products of the sesquiterpene (E,E)-α-farnesene (Anet, 1972a; Huelin and Coggiola, 1970a, 1970b; Huelin and Murray, 1966). Synthesis of sesquiterpenes in plant tissues occurs...

ASA Lessons Learned - 3 - Lester

Adaptive simulated annealing (ASA) is a global optimization algorithm based on an associated proof that the parameter space can be sampled much more efficiently than by using other previous simulated annealing algorithms. The author’s ASA code has been publicly available for over two years. During this time the author has volunteered to help people via e-mail, and the feedback obtained has been...
