Since dental structures are Toothpaste hard and fragile, cross-sectioning of these materials using ultramicrotomy and other techniques and following micro and nano analysis cause problems.The use of FIB-SEM dual beam platforms is the most convenient solution for investigating the microstructures, site-specifically and in certain geometries.Dual bea
As a special class of rice germplasm, wide-compatibility varieties (WCVs) guarantee the fertility of hybrids when there is cross-fertilization between two subspecies.In this study, Chenghui9348 was identified as a new member of the WCV family that improves pollen fertility in an inter-subspecific hybrid.Cytological analysis showed that the abnormal
This article presents a study of the backward bending mode of a simply supported rotating Rayleigh beam with internal damping.The study analyses the natural frequency behaviour of the backward mode according to the internal viscous damping ratio, the slenderness of the beam and its spin speed.To date, the behaviour of the natural Snack Bag frequenc
Due to the importance of increasing the firing precision of self-propelled artillery system corresponding to the projectile impact point, the launch dynamics of self-propelled artillery based on the transfer matrix method for multibody system (MSTMM) is studied in this paper.By using MSTMM to study launch dynamics of self-propelled artillery, there
