"Diabetes offers a serious bar to any kind of operation, and injuries involving open wounds, haemorrhage, or damage to the blood vessels are exceedingly grave in subjects of this disease. A wound in the diabetic patient will probably not heal while the tissues appear to offer the most favourable soil for the development of putrefaction and pyogenic bacteria. The wound gapes, suppurates, and slo...

The ∂̄b complex on the boundary of a complex manifold was first formulated by Kohn-Rossi [KR] to study the boundary values of holomorphic functions and holomorphic extensions. In this paper we study ∂̄b and b on a CR manifold of arbitrary codimension. When the CR manifold M is of codimension 1 and strongly pseudoconvex (or more generally, when M satisfies condition Y (q)), Kohn [K2] proved that b...

reported in the Lancet of 1877 makes no mention of pernicious anaemia nor of koilonychia, a feature in any event not associated with pernicious anaemia. Treves was a many-sided man whose achievements were considerable and varied. In addition to his published work, manuscript sources are available and, in the future, further study of these is likely to provide more understanding of what may seem...

Estimates from the current pulsar birth rate and the number of supernovae to account for the heavy-element abundance suggest that in total 10 to 10 isolated neutron stars exist in our Galaxy. Only a small fraction is detectable as young neutron stars due to their emission of thermal X-rays (for ∼10 years) or pulsed radio emission (for ∼10 years). Proposals that an old ”recycled” population of i...

In 1957, Hans Lewy constructed a counterexample showing that very simple and natural differential equations can fail to have local solutions. A geometric interpretation and a generalization of this counterexample were given in 1960 by L.Hörmander. In the early seventies, L.Nirenberg and F.Treves proposed a geometric condition on the principal symbol, the so-called condition (ψ), and provided st...

culture, colonialism and a hybrid political system, and lastly Marxism with a mixed culture and racial base. The author has drawn on a computer bank of references covering some eight thousand observations on famines over the past six thousand years. The extreme difficulties inherent in recording and analysing famines are recognized. Ten pages of various definitions of famine are given, a good w...
