The matrix cracking along the fiber direction may take place at a tensile load near the hole edge.The matrix cracking can blunt the hole and alleviate the stress concentration.In order to accurately simulate this phenomenon, a three-dimensional finite element model is established based on CDM(continuum damage mechanics).A modeling method for differ
A steel-polymethyl methacrylate (steel-PMMA) beam was fabricated to investigate the vibration properties of a one-dimensional phononic crystal structure.The experimental system included an Flywheel excitation system, a signal acquisition system, and a data analysis and processing system.When an excitation signal was exerted on one end of the beam,
Pesticide use is increasingly under scrutiny for its environmental and human health impacts.While government leaders promote sustainable pest management, including reductions in pesticide usage, growers face pressure to produce agricultural commodities at high cosmetic standards, which often requires the use of pesticides.California (United States)
For many chronic fibrotic conditions, there is a need for local, sustained antifibrotic drug delivery.A recent trend in the pharmaceutical industry is the repurposing of approved drugs.This paper investigates drugs that are classically used for anthelmintic activity (pyrvinium pamoate (PYR)), inhibition of adrenal steroidgenesis (metyrapone (MTP)),
The molecular vibration-activity relationship in the receptor-ligand interaction of adenosine receptors was investigated by structure similarity, molecular vibration, and hierarchical clustering in a dataset of 46 ligands of adenosine receptors.The resulting dendrogram was compared with those of Flywheel another kind of fingerprint or descriptor.Th
