Current harvesting techniques need to be modified to reduce postlarval losses and improve overall stocking densities and pond production.

Based on the results of displacement establishing, it not only allows forecasting of relevant geological hazards but also serves to modernize the reference system. Therefore, it's required to be monitored regularly and continuously. In order to forecast geological hazards based on the results of geodetic data processing, after determining the vertical displacement of stations, it is necessary to determine the vertical displacement velocity of stations. The GNSS measurement data of 4 CORS stations in the Mekong Delta were analyzed for determining vertical displacement by Gamit/Globk software. This study proposed a mathematical model to determine vertical displacement velocity by input data in the geodetic system and geocentric reference system. The analyzing results show that the vertical displacement velocity determined by the two methods has the same value. The minimum absolute velocity for vertical displacement is 0.44 mm/year and the maximum value is 3.69 mm/year.

A problem which is under concerns of many teachers to conduct reseach is how to teach theorems of mathematics actively. Discovery teaching method has been studied by educators around the world and in Vietnam. Recently, several authors have proposed models for teaching theorems by discovery method and teachers can apply these models in teaching effectively. This paper introduces a model for teaching theorems by discovery method with the support of GeoGebra software. This model shows the main steps that teachers can apply in discovery teaching.
