作者： Zhao, M.d. Li, Y.T. dept. of river Eng. Wuhan Univ. Wuhan 430072 China

This paper presents new weighting functions in grid generation and new discretizing scheme of momentum equations in numerical simulation of river flow. By using the new weighting functions, the curvilinear grid could be concentrated as desired near the assigned points or lines in physical plane. By using the new discretizing scheme, the difficulties caused by movable boundary and dry riverbed can be overcome. As an application, the flow in the Wuhan Section of Yangtze river is simulated. The computational results are in good agreement with the measured results. The new method is applicable to the numerical simulation of 2-d river flow with irregular region and moveable boundary.

rodents are a serious constraint to poor farmers in the upland and lowland farming systems of the Lao People’sdemocratic republic and have been described as the pest they have least control over. To better understand theseproblems a baseline survey of farmers was conducted to assess their knowledge, attitudes, and practices with respectto rodent management. A structured survey was conducted in 12 villages across Luang Namtha, Luang Prabang,and Houaphan provinces. Twenty farmers from each village were interviewed (a total of 240 farmers). Farmersnoted that the main factor limiting production was pests (70%), with rats identified as the most important pest(98%). The mean yield loss was estimated at 19% (range 0–100%). Trapping and rodenticides were commonlyused by farmers. Farmers believed that it was important to control rats and believed that rats could only be controlledif farmers worked together. However, 65% of farmers conducted rodent control by themselves, and 92% offarmers believed that rodenticides were harmful to the environment. The main constraints identified were the highcost of some control methods and the need to get farmers to work together as a community.

A collection of brachiopods by the Institute of Oceanology . Academia Sinica (Qingdao ). contains eight species from seven genera. Six of the species have been recorded previously from Chinaseas -- Lingula adamsi . L. anatina, discinisca Stella. Pelagodiscus allanticus, Campages mariae,Terebratalia coreanica . Two species (Terebratulina hataiana and Frenulina sanguinolenta)have been described from other parts of the Pacific area . The apparent absence of any endemic species is a noteworthy feature of Chinese in comparison with Japanese faunas .
