To assess these DNA breakages, quantitative analysis of the extent of DNA breakage has been performed by analyzing AFM images.
The extent of breakage of these particles is related to the prevailing shear stresses and strains.
However, the extent of breakage per impeller revolution is independent of impeller rotational speed.
A method of predicting the extent of breakage occurring due to agitation is described and applied for Paracetamol in a small-scale dryer.
A dimensionless attrition propensity parameter is derived from the above approach, whereby the extent of breakage is related to the material properties and impact conditions.
The breakage rate and the extent of granule attrition is also found to decrease with increased bed temperature and increased fluidising air velocity.
If these breaks are not repaired, the resulting persistent DNA damage can give rise to mutations and genomic instability that subsequently cause secondary cancers [11 13] or cell death [14], with the precise outcome depending on the overall extent of breakage.
The breakage mode depends on the extent of plastic flow, which cannot be explained by elastic solutions.
Most importantly, it is found that the extent of particle breakage is a function of the work performed on the material, and the parameters in this function depend on the particle-particle and particle-wall friction coefficients.
The circumstances under which dry spots appear on the exchange surface for the film breakage, as well as the extent of the wetted part of the surface and the liquid vapor interface, are critical to predict and control the performances of these devices.
