摘要:Abstract(#br)The highest risk to structures during their lifetime is generally during the construction phase. This is evidenced by the fact that most structural failures occur during the placement of fresh concrete in construction rather than after the structure is completed and ...

摘要:Abstract(#br)Work performed on scaffolds carries the risk of falling that disproportionately threatens the safety and health of novice construction workers. Hence, objective measures of the postural stability, cardiovascular stress, and subjective difficulty in maintaining postur...

摘要:A novel strategy for the construction of the phthalazin-1(2 H )-one scaffold has been developed by means of a copper-mediated cascade C–H/C–H coupling and intramolecular annulations and a subsequent facile hydrazinolysis. This C–H activation transformation proceeds smoot...

摘要:Abstract A small series of hydantoins was efficiently synthesized via a two-step Ugi/cyclization reaction sequence using alkyne group as a leaving group under basic conditions. This microwave-assisted one-pot cyclization strategy could be applicable to other multicomponent reacti...

摘要:Abstract The construction of engineered bone mostly focuses on simulating the extracellular matrix (ECM) for proper biological activity. However, the complexity of architecture and the variability of the mechanical properties of natural bones are related to individual differ...
