Based on a metaresearch study by Ioannidis et al., [8] the new c-score is calculated by an algorithm that combines all scientific research fields and ranks research from the Scopus database across all research areas, even from those with lower citation density.
the number of times the articles in the journal were cited during the year by later articles in itself and other journals, the number of citations made from articles published in the journal that year to it and other specific individual journals during each of the most recent ten years (the 20 journals most cited are included)
These citation indices were used both for general and for legal study. The Talmudic citation index En Mishpat (1714) even included a symbol to indicate whether a Talmudic decision had been overridden, just as in the 19th-century Shepard's Citations. [4] [5] Unlike modern scholarly citation indexes, only references to one work, the Bible, were ...
The aldol reaction is an important carbon-carbon bond forming reaction in organic chemistry [1] [2] [3] involving the addition of an enol or enolate anion to an aldehyde or ketone. [ 4 ] [ 5 ] In the aldol addition , the reaction results in a β-hydroxy ketone (or aldehyde ), also called an "aldol" ( ald ehyde + alcoh ol ).
Citation templates have been created for a number of commonly used textbooks: some examples are given below, and the complete list can be found at Category:Chemistry citation templates. Please include page numbers or page ranges ( page = or pages = parameters respectively) when using these templates.
A journal's SJR indicator is a numeric value representing the average number of weighted citations received during a selected year per document published in that journal during the previous three years, as indexed by Scopus. Higher SJR indicator values are meant to indicate greater journal prestige.
The ACS Style is a set of standards for writing documents relating to chemistry, including a standard method of citation in academic publications, developed by the American Chemical Society (ACS).
In chemistry a donor number (DN) is a quantitative measure of Lewis basicity.A donor number is defined as the negative enthalpy value for the 1:1 adduct formation between a Lewis base and the standard Lewis acid SbCl 5 (antimony pentachloride), in dilute solution in the noncoordinating solvent 1,2-dichloroethane with a zero DN.
