The article examines Brazilian refined earthenwares known as faiança fina (fine faience) and relates ideas about its production to the contextual backdrop of hygienist discourses in the city of São Paulo in the early twentieth century. Based on an analysis of glaze components, moisture expansion processes, and technological aspects of the production of earthenware recovered from the Petybon arc...

Abstract There were studied glaze layers of fragments painted tiles estimated by art historians basing on external signs as fabricated in the Netherlands 18 th century. The paper presents results surface composition measurements X-ray fluorescence (XRF) and photoelectron spectroscopy (XPS), time-of-flight mass-spectroscopy (TOF-$$$SIMS) methods comparison with literature data. Information inclu...

Determining the aero-icing characteristics is key for safety assurance in aviation, but it may be a computationally expensive task. This work presents framework development of low-dimensional models application to aerofoil icing. The builds on: an adaptive sampling strategy identify local, nonlinear features across icing envelope continuous intermittent icing; classic technique based on Proper ...

Abstract This paper analyzed five dragonfly eye beads excavated from M176 of the Hejia Cemetery in Late Warring States period (around 3rd c. BC) by using a super depth field 3D microscope system (OM), scanning electron microscope-energy dispersive spectrum (SEM–EDS) and Raman spectroscopy. The analytical results confirmed that all were glazed pottery glaze material belongs to lead-barium-silica...
