Experience shows that there is a strong parallel between metrization theory for compact spaces and for linearly ordered spaces in terms of diagonal conditions. Recent theorems of Gruenhage, Pelant, Kombarov, and Stepanova have described metrizability of compact (and related) spaces in terms of the offdiagonal behavior of those spaces, i.e., in terms of properties of X −∆. In this paper, we show...

Old masonry buildings, which are frequently part of the cities-built heritage, vulnerable to seismic actions. Thus, it is important conduct efficient strengthening interventions that allow maintenance existing building minimize environmental and economic impact. The use reinforced renders a simple effective solution for this type constructions. In paper, several compositions analyzed, consistin...
