The initial phase (solid or aqueous droplet) of aerosol particles prior to activation is among the critical factors in determining their cloud condensation nuclei (CCN) activity. Single-particle levitation in an electrodynamic balance (EDB)was used to measure the phase transitions and hygroscopic properties of aerosol particles of 11 organic compounds with different solubilities (10(-1) to 102 ...

Abstract The unique pre-Mongolian twelfth century wall painting from the Christ's Transfiguration Cathedral of Mirozhsky Monastery in Pskov (Russia) have been investigated. A little less than 200 XRF spectra were collected situ by portable spectrometer. Moreover 19 samples subjected to additional in-depth laboratory analysis six complimentary physico-chemical methods: neutron activation analysi...

Pathologies in concrete structures, such as cracks, splintering, efflorescence, corrosion spots, and exposed steel bars, can be visually evidenced on the surface. This paper proposes a method for automatically detecting these pathologies from images of structure. The proposed uses deep neural networks to detect images. results time savings error reduction. presents wide-angle containing overall...

The chemical compositions of the aqueous phases in alkali-activated slag (AAS) paste and Portland cement (PC) were determined up to 28 d with aim obtaining a better understanding stability hydration products two binder systems. saturation levels respect PC AAS obtained by thermodynamic modelling. main findings this study were: effective index for portlandite system was always below zero sulfate...

This document contains additional material for the paper ”Image-Guided Weathering: A New Approach Applied to Flow Phenomena”. This material consists of a set of maps and parameters obtained for different stain exemplars. For each exemplar, the following maps are shown: the input stain image, the extracted degree map, the simulated stain after fitting the parameters, the synthesized detail map, ...

We describe the performance of a microclimate monitoring system that was implemented for the preventive conservation of the Renaissance frescoes in the apse vault of the Cathedral of Valencia, that were restored in 2006. This system comprises 29 relative humidity (RH) and temperature sensors: 10 of them inserted into the plaster layer supporting the fresco paintings, 10 sensors in the walls clo...
