The clearance flow between the nozzle and endwall in a variable geometry turbine (VGT) has been numerically investigated to understand the clearance effect on the VGT performance and internal flow.It was found that the flow Examination rate through turbine increases but the turbine efficiency decreases with height of clearance.Detailed flow field a
Erect-crested penguins are the least studied of all penguins.They breed on two isolated subantarctic island groups, the Antipodes and Bounty Islands.Sporadic nest counts indicate a dramatic decline in numbers of erect-crested penguins over the last 50 years.Here we present data from a study undertaken in 1998 on the breeding biology, behavior and h

Vitex negundo var.heterophylla (Franch.) Rehder is a common small shrub in northern China.In order to study the fine nectar characteristics and water and soil conservation characteristics of V.negundo, the analysis of chloroplast genome would provide theoretical basis for economic development and germplasm utilization of V.negundo.The Joint/Bone su
