BASE 包括:Basically Available(基本可用)、Soft state(软状态)、Eventually consistent(最终一致性)。 针对数据库系统要求的可用性、一致性,BASE放宽要求,形成基本可用和软状态/柔性事务。而一致性是最终目的。 ACID vs.BASE
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
Cloud cover data were based on an oktas scale, where 0 represents a clear sky and 8 is fully overcast (SHMI). Measurements were performed on sunny days with a clear or almost clear sky (scale 0-2, n = 3), partly cloudy days (scale 3–5, n = 5), and on almost fully ...
Biotechnological ProductionBenzoic acid is exclusively chemically synthesized on an industrial scale. Toluene from petrochemical routes is oxidized in the presence of the catalyst potassium permanganate to benzoic acid . However, a recent study described for the first time a benzoic acid production process...
It is imperative to stress that any method used for large-scale codon reassignment will carry an inherent limitation of being contaminated with uncertainty and error. The main reason is that codon optimization is very commonly used to improve heterologous gene expression25, especially in structure ...
Acetic acid is used in numerous industrial chemical preparations and the large-scale productionof acetic acid takes place through several processes. The main method of preparation ismethanol carbonylation. In this process, methanol reacts with carbon monoxide to give aceticacid: CH3OH(l)+ CO(g)→...

Methacrylic acid is produced industrially on a large scale as a precursor to its esters, especially methyl methacrylate (MMA) and poly(methyl methacrylate) (PMMA). The methacrylates have numerous uses, most notably in the manufacture of polymers with trade names such as Lucite and Plexiglas. MAA...
