The purpose of the study is to update and historiographically summarize publications devoted to the study of the characteristics of the pedagogical and educational activities of Russian emigrant musicians in the United States during the first wave of Russian emigration Half Yard Bundles (1918 - late 1930s), as well as its consequences.The sources o
Comparative Profiling of microRNA Expression in Soybean Seeds from Genetically Modified Plants and their Near-Isogenic Parental Lines.
MicroRNAs (miRNAs) have been widely demonstrated to play fundamental roles in gene regulation in most eukaryotes.To date, there has been no study Propolis describing the miRNA composition in genetically modified organisms (GMOs).In this study, small RNAs from dry seeds of two GM soybean lines and their parental cultivars were investigated using dee
Summary determination of velocity and acceleration in the dead position of four-bar mechanism by the stopping method
The paper studies a plane four-bar mechanism in a dead, kinematically indeterminate position.From that position, the mechanism could Propolis continue to move, continuously, or the driven lever would stop and move backwards.But, if we eliminate this second possibility, the position of the mechanism is no longer indeterminate and it would be logical
A Study on the Influence of Nonlinear Vibration on Fretting Damage of Involute Spline Pairs in Aero-Engines
To meticulously examine the repercussions of nonlinear vibrations on fretting damage within aero-engine involute spline pairs, a dynamic model was constructed rooted in well-established theories and methodologies.MATLAB was engaged to resolve the model, where the vibration displacement function was treated under Fourier transformation.The emergent
