City logistics is one of the significant branches of supply chain management, dealing with the logistics and transportation activities in urban areas. This research area has recently appropriated an exponential growth of publications. This paper presents a bibliometric analysis along with a systematic literature review to organise the results of surveying more than 370 papers and research works published since 2010. We identify the top contributing research topics. The most common keywords used in the city logistics literature are referred to in order to propose six research categories identifying the main innovative research perspectives.  相似文献

The qualitative properties of processed cheese (PC) fortified with different levels of asparagus powder (AP) (0.5%, 1% and 1.5% wt/wt) were evaluated during storage. AP decreased the pH and lipolysis indexes and increased the phenolic content, antioxidant activity and proteolysis of the processed cheeses. AP made the structure of the cheese more elastic, increased the rigidity and decreased the spreadability compared with the control sample, which corresponded to the results obtained using dynamic oscillatory rheometry. The results showed that AP as a rich source of bioactive components could be used for the fortification of processed cheeses.  相似文献

Abstract  

Reaction mechanisms of ethanol conversion to ethylene over H–ZSM–5, Cu–ZSM–5, Ag–ZSM–5, and Au–ZSM–5 catalysts were investigated using density functional theory calculations. Energetics, thermodynamic quantities, rate and equilibrium constants of ethanol conversion to ethylene were obtained using the B3LYP/LanL2DZ method. The catalytic abilities of these catalysts on the reaction rates of ethanol conversion to ethylene are in order: Au–ZSM–5 > > Ag–ZSM–5 > H–ZSM–5 > > Cu–ZSM–5.  相似文献
