Purpose Building on the recent capability-based conceptualisation of resilience, this paper aims to explore whether experience a previous crisis and entrepreneur resilience are associated with Small- medium-sized enterprises (SMEs') adoption different anticipation strategies for adversities. Design/methodology/approach Using original survey data 959 Italian German SMEs, research uses multinomia...
This paper explores, for the first time, the possibility of carbonating waste metallic iron powder to develop sustainable binder systems for concrete. The fundamental premise of this work is that metallic iron will react with aqueous CO2 under controlled conditions to form complex iron carbonates which have binding capabilities. Chosen additives containing silica and alumina are added to facili...
Using [(1)H,(15)N] heteronuclear single quantum coherance (HSQC) NMR and (15)N-labeled carboplatin, 1, we show that Jurkat cells affect the rate of disappearance of the HSQC NMR peak in culture medium for this Pt(2+) anticancer drug. The decay or disappearance rate constant for 1 in culture medium containing cells is k(1)=k(c)[CO(3)(2-)]+k(m)+k(u)N, where k(c) is the rate constant for reaction ...
