Stir Bar Sorptive Extraction of Volatile Compounds in Vinegar: Validation Study and Comparison With Solid Phase Microextraction [PDF]

, 2007
Stir bar sorptive extraction was evaluated for analysing volatiles in vinegar. The procedure developed shows detection and quantitation limits, and linear ranges adequate for analysing this type of compounds. The accuracy obtained was close to 100%, with

Repeatability of evolution on epistatic landscapes

, 2015
Evolution is a dynamic process. The two classical forces of evolution are mutation and selection. Assuming small mutation rates, evolution can be predicted based solely on the fitness differences between phenotypes.

We need another 3R rule: repeat, repeat, repeat!

Journal for Reproducibility in Neuroscience, 2021
There is consensus within the scientific community that replication studies are scientifically sound and bring added value and reliability to any discovery. It is also widely acknowledged that replications are not as common as they perhaps should be.

The dependence of acoustic emission behavior on prior fatigue loading history

Frontiers in Built Environment, 2022
Fatigue cracks are a major concern for aging metallic structures, as they can cause unexpected catastrophic failure. They often occur on hidden surfaces, e.g., under paint and rust or on the interface between two structural layers, which makes visual ...
