parechoviruses form one of the nine genera in the picornaviridae family, and include two human pathogens: human parechovirus type1 and 2 (hpev1 and hpev2). the genome of picornaviruses encodes a single polyprotein, which undergoes a cleavage cascade performed by virus encoded proteases to give the final virus proteins. the primary cleavage occurs by 2a protein and this step is critical for vira...

Abstract The existence of off‐cycle catalyst cooperativity in amine/metal combined catalysis is disclosed. experimental and density functional theory study the co‐catalyzed enantioselective Michael/carbocyclization cascade reaction between allenes α,β‐unsaturated aldehydes reveals that dual catalysts can perform gives access to stable bicyclo[3.2.0]heptane species limits carbocycle product form...

fresh juices of colourful wild berries: cornelian cherry, blackthorn, white beam and elderberry are considered as valuable, highly nutritive beverages and characterized by the high level of vitamins and antioxidant capacity. the concentration process of these juices by membrane osmotic distillation was studied, where only water vapour is eliminated, while the heat sensitive, valuable compounds ...

 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...
