Dry ice blasting is a technology that has been widely studied and applied in different industrial sectors as an alternative to the use of solvent, water, or abrasive spraying methods. It is a CO2 spraying system capable of balancing efficiency and sustainability with a wide variety of equipment available on the market. This study analyses and compares cryo-cleaning equipment manufactured by pioneering companies in the cryogenic industry. Based on data sheets, safety data sheets, and contact with manufacturers, a quantitative comparative study has been carried out. The aim of this study is to identify those with the best performance, efficiency, and adaptability to operational and environmental requirements. The results reflect the strengths and weaknesses of the equipment in terms of occupational safety and operability. These have been discussed and evaluated, recognising improvements of this technology, which is capable of removing surface layers of different natures without altering the underlying substrate.

This research aims to analyze the breastfeeding experiences of incarcerated mothers in the prisons of the Spanish penitentiary system. Additionally, it explores whether these mothers have perceived practices related to obstetric violence during pregnancy, childbirth, and the postpartum period. An exploratory-descriptive study was conducted using a qualitative approach and a critical ethnographic method. Fieldwork, including participant observation and semi-structured interviews, was carried out between December 2021 and April 2022. The study involved 30 adult women from Africa, Europe, Eastern Europe, and Latin America, all serving sentences with their infants in Mother Units located in the Spanish cities of Alicante, Barcelona, Madrid, and Seville. The main findings highlight the need for penitentiary policies with a gender and feminist perspective. These policies should aim to eliminate severe inequalities and discriminations faced by incarcerated women while protecting the basic rights of both mothers and infants.
