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.
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
The phrase "bugger me" is a slang term used for a situation that has yielded an unexpected or undesirable result. Common usage includes "bugger me dead" and "bugger me blind". [ 13 ]
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.
Sometimes the Germanic term has become rare, or restricted to special meanings: tide, time/temporal, chronic. [13] Many bound morphemes in English are borrowed from Latin and Greek and are synonyms for native words or morphemes: fish, pisci-(L), ichthy-(Gk). Another source of synonyms is coinages, which may be motivated by linguistic purism.
The word "bumper" in this context comes from a usage that means "something unusually large", [1] which is where this term comes from. [ 2 ] Though very productive harvests often have positive implications for the producer, a bumper crop can also be a source of problems, such as when there is insufficient storage space ( barns , grain bins , etc ...
A definition states the meaning of a word using other words. This is sometimes challenging. Common dictionaries contain lexical descriptive definitions, but there are various types of definition – all with different purposes and focuses. A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols).
