Science, 1987
In the letter "Tanker 'dumping' regulations" by T. S. Wyman (5 June, p. 1160), the years of amendations to the International Convention for the Prevention of Pollution from Ships, 1973, mentioned in the second paragraph, were incorrect. The amendations were made in 1978, 1984, and 1985 (not 1987).

Coupler jack-knifing and derailment of slave control locomotives in 20,000-tonne heavy-haul trains usually occur due to the combinations of large in-train forces with poor track conditions. This paper presents an experimental investigation on the dynamic

Reciprocal relationship between locomotive syndrome and social frailty in older adults
Geriatrics & Gerontology International, 2021States of vulnerability are multidimensional and become more prevalent with advancing age. These states and the causal relationships between them, merit thorough investigation.

Effects of wheelset flexibility on locomotive–track interaction due to rail weld irregularities
Vehicle System Dynamics, 2021Irregularities of rail joints ordinarily induce high-frequency impacts on wheel–rail contact systems, which may further influence vehicle–track interaction. In this study, a three-dimensional locomotive-track coupled dynamics model that uses the wheelset

Abstract Not all gastropods are slow moving. The pelagic species, such as the pteropod Clione, are strong swimmers that can swim at speeds up to 50 cm/second. However, the vast majority of gastropods locomote not by swimming, but by crawling, and they are indeed slow.

Wheel/rail dynamic interaction induced by polygonal wear of locomotive wheels
Vehicle System Dynamics, 2020Serious wheel polygonal wear usually causes drastic wheel/rail interactions, which threats the running safety of railway vehicles. This paper presents an investigation into the effect of polygonal wear of heavy-haul locomotive wheels on the dynamic ...
