Environmental Impact Assessment of an Innovative Sustainable Thermoplastic Anticorrosion Coating for Aluminum Alloy AA2024

open access: yesPolymer Engineering &Science, EarlyView.
Life cycle assessment reveals that recyclable PPM coatings significantly reduce environmental impacts compared to epoxy, promoting sustainable aerospace corrosion protection. ABSTRACT This study evaluates the environmental performance of an innovative thermoplastic anticorrosion coating based on poly(phenylene methylene) (PPM) for aluminum alloy AA2024,

Nucleon Resonance Excitation with Virtual Photons [PDF]

open access: yes, 2006
The unitary isobar model MAID is used for a partial wave analysis of pion photoproduction and electroproduction data on the nucleon. In particular we have taken emphasis on the region of the Delta(1232) resonance and have separated the resonance and ...

The relationship between seasonal mean temperature and most extreme day

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In Northern Hemisphere winter, there is a strong correlation between seasonal mean temperature and coldest daily mean temperature which varies in magnitude from one region to another (with a weaker relationship in summer between mean and hottest day).

Serendipitous ritualization: dynamics of lay connectivity in Chinese Buddhist temples and beyond Ritualisation fortuite : dynamique de la connectivité des laïques dans les temples bouddhistes chinois et au‐delà

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article contributes to rethinking the dichotomy between informal sociality and ritual formality by examining the occasional ritual encounters surrounding spirit‐tablet inscription in Chinese Buddhist temples. Rather than viewing rituals as enactments of established orders, it presents ritual engagement as a contingent process of relational ...

Mothers against the natural order: Gender representations and desertion of identities in the drama of disinheriting a son in eighteenth‐century Barcelona  

open access: yesGender &History, EarlyView.
ABSTRACT The disinheritance of a firstborn son accustomed to the privileges of exclusion has for centuries been a dramatic event for families, especially if the decision was taken by a woman, the son's own mother. Very few dared to do so, because it symbolised a break with the notion of virtuous, compassionate motherhood; it represented a failure to be
