In this study, we have developed a propulsion mechanism using a fin COSMETICS with variable effective length spring as variable stiffness mechanics.We measured its thrust and the lateral forces in water tank with three dimensional flow and that with quasi two dimensional environment.Additionally, three dimensional numerical analysis of the propulsi
Accurate estimation of tree position, diameter at breast height (DBH), and tree height measurements is an important task in forest inventory.Mobile Laser Scanning (MLS) is an important solution.However, the poor global navigation satellite system (GNSS) coverage under the canopy makes the MLS system unable to provide globally-consistent point cloud
Dasiphora fruticosa comprises male, female and hermaphrodite plants, which are distributed Ribbed Turtleneck sympatrically in some populations on the Qinghai-Tibet Plateau.To explore what governs the coexistence of these three sexual phenotypes, we investigated the DNA contents, pollen and ovule production, pollen deposition, and performed hand-pol
This study focuses on the search for a natural treatment to reduce lead toxicity in male Wistar rat by using the aquous extract of wheatgrass Triticum aestivum (WG).In addition to the control group (C), rats were exposed to a diet containing 600 mg Pb acetate/Kg diet (Pb), or combined with the WG at 9g/100g diet (Pb-WG) for a period of 6 weeks.Bioc
