This paper presents a series of design curves to aid in the selection of turret mooring systems for tankers based Floating Production Storage and Offloading (FPSO) systems. These curves are appropriate to water depths ranging from 100 m to 600 m. The curves can be used as a preliminary design tool, allowing the designer to quickly evaluate alternative mooring system configurations, including the number of mooring lines, the characteristics of chain and wire rope to be deployed and the. initial tension. With a knowledge of the total environmental force and vessel motion characteristics, the designer can determine the appropriate system for closer evaluation.

THE Yellow River, with its huge amount of silt charge from the Loess Plateau, is the secondlargest river in China. Its lower reach has become a famous hanging river because of serioussilting up, and the magnitude of discharge changes much from season to season. As a result ofsilting, migration of the stream channel happens frequently. Lateral erosion of channel or pointbars, and scarp slopes forming during the erosion may be often observed. The silt stalactite,hitherto not reported, usually forms on surfaces of the slope. As a newly found kind of sedirnen-tary structure, the silt stalactite may have some significance to the study of sedimentary envi-ronments and paleoclimate.

SCIENTISTS have paid much attention to sex control of animals. Sex control of shrimp is a noticeable topic in the field of high technology in aquaculture. Increasing the proportion of female shrimps in a rearing population is undoubtedly a very effective path to obtain higher aquacultural production of Penaeus chinensis. But up to date, the mechanism of sex differentiation and determination in shrimp is not clear. In recent years, we have done some work on
