Studies on the Kinetics of Thermal Decomposition of Copper Oxalate Mixed With Silver Oxalate
Abstract: The coprecipitates, Ag2Cu(C2O4)nH2O of varying composition [Ag = (1 and 2)%], have been synthesized and were characterized by means of IR, XRD, and SEM. The decomposition of the prepared oxalates was monitored by differential scanning calorimetry (DSC) and thermogravimetry (TG). The DSC studies reveal that the decompositions of the mixed oxalates were all complex exothermic processes with resemblance to the exothermic reaction of copper oxalate and ranges from 540 to …

Cost Impact of Structural Irregularities
Abstract: Since absolute regularity is an idealisation that seldom exists, building structures are typically irregular. Building irregularities are unavoidable because of the many practical and aesthetic benefits. The performance of buildings subjected to earthquake pressures has revealed that asymmetric and irregular constructions produce more severe damage than regular structures, and the collapse of these structures may be blamed for the majority of human fatalities. Vertical mass inconsistency is commonly due to …
