Soybean root rot is an important disease that has affected soybean crops in recent years, but the available control methods still do not provide good protection for soybeans.In this study, three biodegradable mulch films (HML@CMCS, HML@PVA, HML@CMCS/PVA) were prepared from carboxymethyl chitosan (CMCS) and polyvinyl alcohol (PVA), and hymexazol (HM
The new design of a resilient element for application in drilling devices of vibration protection is presented.A cylindrical shell with a cut along its generatrix is the peculiarity of the proposed design.The presented resilient element has high loaded and damping properties upon cross dimension hard restriction condition.Besides, the design is sim
The aim of study is to confirm a new technique that can crush the frozen soil and/or ice block using underwater shock wave generated by the underwater explosion of explosive.This technique can lead to the earlier sowing, which can have the larger harvest because the duration of sunshine increases.Especially, in Hokkaido prefecture, Japan, if the so
