A scientific exegesis of "Youth" by Joseph Conrad

Abstract: The novelist Joseph Conrad, whose most famous work is probably ‘Lord Jim’, himself worked at sea between the ages of 14 and 40, and in a short work entitled ‘Youth’ [1] gives a biographical account of a voyage in the 1880s from England to Bangkok with a coal-bearing vessel. In the event, there was spontaneous heating of the coal and consequent shipwreck. The author of this note has been interested in spontaneous heating of coals for many years but was unaware of this account until recently. Though steam vessels were in use by the time of the Conrad story, the coal-bearing vessel (‘barque’) was propelled by sails only. It is clear from Conrad’s account that seamen accustomed to working with coal as cargo could sometimes judge intuitively, from appearance and possibly background odour, whether a particular shipment they had been assigned was or was not susceptible to spontaneous heating. Some weeks after leaving England, by which time the vessel was in the Indian Ocean, the consignment of coal began, in Conrad’s words, to ‘smoke in earnest’. There had previously been detection, purely by olfactory means, of released gases and vapour, but it was the appearance of smoke which caused the vessel’s crew to go into ‘emergency mode’. The captain of the vessel made a decision to continue for Bangkok instead of putting in at an intermediate port, and continuous admittance of sea water to the cargo of coal led to cessation of smoke

A Model for Critical Behaviour in a Liquid Explosive Experiencing Dual Ambient Temperatures- Part 2. Temperature Trajectories and Times to Explosion

Abstract: A PREVIOUS PAPER [1] established the basic theoretical framework for a situation in which a stirred liquid explosive was mounted in a heating chamber in such a way that half of its outside surface area was experiencing ambient temperature To and the other half ambient temperature T., where To > TQ. Specifically, it was shown that whereas a cylindrical charge of the liquid explosive DINA 7.5 cm high and 3.75 cm in diameter was critical with a single To of 431 K, with To 431 K and Ta 426 K the corresponding dimensions were 10.2 cm height and 5.1 cm diameter. The reader is referred to the earlier work for a full discussion. In this paper we integrate the heat balance equation for each of the above cases, and examine times to explosion.

Simultaneous Combination and Nearly Self-similar Pulse Compression of Five Pulses at Different Wavelengths

Abstract: Numerical simulation of five raised-cosine pulses with spectral separation of 0.1 nm with each other merged into a single compressed pulse (12.8 compression factor) of nearly 50% of total input energy in a dispersion decreasing nonlinear fiber is reported.
