Apoptosis has been a biological phenomenon of intense interest for 20 years, but the earlier morphological features of apoptosis have not been determined hitherto.Using the methods of semi- and ultrathin sections, the livers of intact embryos and young rats have been studied under the effect of cycloheximide to determine morphological features of a
A new analytical model of a logarithmic sprag clutch considering profile modification is proposed Art for Kids to reflect the effect of profile parameters on the dynamic contact pressure distribution during the engagement, especially the edge stress of a sprag roller.In the model, a nonlinear iteration method of normal force including the logarithm
Theoretical and empirical evidence are synthesized to show that underwater acoustic sensing techniques may provide a valuable tool for measuring the wind speed and determining the destructive power of a hurricane.This is done by first developing a model for the acoustic intensity and mutual intensity in an Eye Pencil ocean waveguide due to a hurric
In recent years, there has been an increase in deaths due to infectious diseases, most notably in the context of viral respiratory pathogens.Consequently, the focus has shifted in the search for new therapies, with attention being drawn to the use of nanoparticles in mRNA vaccines for targeted delivery to improve the efficacy of these vaccines.Nota
Through core observation, thin section identification, and logging and testing data analysis, the types and Waders characteristics of event deposits in the ninth member of Yanchang Formation of Triassic (Chang 9 Member) in southwestern Ordos Basin, China, are examined.There are 4 types and 9 subtypes of event deposits, i.e.earthquake, gravity flow,
