The objective of this study is to analyze the impact of solid particle size on the thermal sterilization process of canned food using Computational Fluid Dynamics (CFD). The study investigates how different particle sizes influence heat transfer efficiency, heating rate, and overall process lethality. A CFD-based model, validated against experimental data, is employed to assess temperature distribution and determine the slowest heating zone (SHZ) for various particle configurations.

This study evaluates the potential of Optical Coherence Tomog
raphy (OCT) as a non-invasive tool for retinal age prediction in
healthy individuals. A dataset comprising 1,180 eyes from 517 con
trol subjects was used to compare deep learning models trained on
different OCT scan types: peripapillary B-scans, individual macula
raster B-Scans, and full macular volumes. Images underwent stan
dardized preprocessing, and models based on 2D and 3D ResNet
architectures were trained and optimized using Transfer Learning.
Results show that volumetric macular scans applied in a ResNet
3D model achieved the lowest Mean Absolute Error (3.07 years),
outperforming both previous literature and all tested 2D configura
tions. Overall, findings highlight that integrating depth and spatial
features in OCT data significantly enhances retinal age estimation.

This study examines the influence of gender composition of the governing council (GC) and senior management council (SMC) of worker cooperatives on the distribution of cooperative surplus. The analysis relies on a panel dataset of 383 observations from 82 worker cooperatives, member firms of the MONDRAGON Corporation, over the period 2010–2022. Using the System generalized method of moments panel data methodology, the results indicate that gender composition does have an impact. Data on GCs’ gender composition on surplus distribution suggest that a higher proportion of women on these councils is associated with lower surplus allocations, in line with the substitution perspective of agency theory and several studies on women's behaviour in decision-making bodies. Conversely, in the case of the SMCs, a positive relationship is observed between the proportion of women and surplus distribution. Although agency conflicts should be minimal in the cooperative context, the different results observed between the two governance bodies suggest that certain agency effects may be present. This suggests that the configuration and functioning of decision-making bodies can play a key role in how surpluses are managed and distributed. These findings contribute to the literature by advancing our understanding of gender effects on senior-level financial decision-making processes in worker cooperatives.
