Drosophila exoribonuclease nibbler is a tumor suppressor, acts within the RNAi machinery and is not enriched in the nuage during early oogenesis

Hereditas, 2017
Background micro RNAs (miRNAs) are important regulators of many biological pathways. A plethora of steps are required to form, from a precursor, the mature miRNA that eventually acts on its target RNA to repress its expression or to inhibit translation ...

Molecular dynamics simulation of reinforcement of mechanical properties of nitrile rubber by adding nano-zirconia

Hecheng xiangjiao gongye, 2022
The molecular model of nano-zirconia reinforced nitrile rubber （NBR） composite was established by molecular dynamics simulation. The reinforcement effects of three forms of nano-zirconia, namely, external filling, in-situ filling, and in-situ filling and

Modeling n‐Butyl Acrylate Polymerization using Complementary Modeling Techniques

Macromolecular Reaction Engineering, EarlyView.
Two different simulation methods are used for the radical polymerization of nBA: deterministic in Predici and stochastic with mcPolymer. It has been successfully implemented across a wide temperature range. It turns out that the partially different implementation of chain‐length‐dependent termination and β‐scission are important for obtaining ...

Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, EarlyView.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...

Modal performance degradation of naturally aged NBR

Polymer Testing, 2022
Damping is often an invisible requirement for a good mechanical design. To render the long-term service of viscoelastic dampers, it is essential for design engineers to estimate the degradation of the damping characteristics with age.

Analysis of the influence of supplementary reinforcement on the behavior of reinforced‐concrete two‐pile caps subjected to concentric and eccentric loading

Structural Concrete, EarlyView.
Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found
