Relation between chemical reaction conversion selectivity and yield. In chemical reaction engineering, "yield", "conversion" and "selectivity" are terms used to describe ratios of how much of a reactant has reacted—conversion, how much of a desired product was formed—yield, and how much desired product was formed in ratio to the undesired product—selectivity, represented as X, S, and Y.
Crop yield, measurement of the amount of a crop harvested, or animal products such as wool, meat or milk produced, per unit area of land . Yield (wine), the amount of grapes or wine that is produced per unit surface of vineyard
Under normal market conditions, long-term fixed income securities (for example, a 10-year bond) have higher yields than short-term securities (e.g., a 2-year bond). This reflects the fact that long-term securities are more exposed to the uncertainties of what could happen in the future—especially changes in market rates of interest.
Yielded structures have a lower stiffness, leading to increased deflections and decreased buckling strength. The structure will be permanently deformed when the load is removed, and may have residual stresses. Engineering metals display strain hardening, which implies that the yield stress is increased after unloading from a yield state.
The meanings of these words do not always correspond to Germanic cognates, and occasionally the specific meaning in the list is unique to English. Those Germanic words listed below with a Frankish source mostly came into English through Anglo-Norman, and so despite ultimately deriving from Proto-Germanic, came to English through a Romance ...
Yield management (YM) [4] has become part of mainstream business theory and practice over the last fifteen to twenty years. Whether an emerging discipline or a new management science (it has been called both), yield management is a set of yield maximization strategies and tactics to improve the profitability of certain businesses.
A farmer can invest a large amount of money to increase his yields by a few percent, for example with an extremely expensive fertilizer, but if that cost is so high that it does not produce a comparative return on investment, his profits decline, and the higher yield can mean a lower agricultural productivity in this case. A yield is a 'partial ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
