The geochemical analyzes revealed that the original magma could be a mantle origin of high iron and magnesium containing basalt （tholeiites, 10%-15%）. As regards to the palaeogeographic environment, it can be said that due to the periodic sea flooding, it pushed into a lower area, covered with sediment where the surrounding areas were highlighted （biikkszentkereszt and bukkszentlaszl6 tufts）.展开更多

However, in vivo studies are largely limited, and little is known about whether E2 exerts similar effects on both female and male zebrafish （Danio rerio）. Here, we show exposure of both sexes ofD. rerio to 20 nmol/L E2 resulted in a significant increase in Vgl expression, but caused little damage to the hepatocytes, suggesting that this is the optimum E2 concentration. Also, exposure to 20 nmol/L E2 for 20 days caused a marked increase in plasma IgM levels, but had little influence on the peripheral leukocyte density, providing the first evidence of a hormone-immune system interaction in this species.展开更多

In this paper, we mainly discuss the research methods of several interface mechanical properties and propose the possibility of studying the mechanical properties of the steel tube reinforced concrete composite pile by using the principle of ultrasonic speckle.展开更多
