Safety Science and Technology, EarlyView.This study investigated the combustion characteristics of mixtures of the environmentally friendly flame retardant HFO‐1225zc with three combustible working fluids (HFO‐1234yf, HFC‐32, and HFO‐1243zf). The flame retardant efficacy of HFO‐1225zc on three working fluids decreases in the order: HFO‐1234yf, HFC‐32, HFO‐UFL1243zf. ABSTRACT The environmental

Sedimentology, EarlyView.ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...
