| Hofmeister series | <chemistry> The series of cations Magnesium, Calcium, Sr2+, Ba2+, Li+, Na+, K+, Rb+, Cs+, and of anions citrate3-, tartrate2-, SO42-, acetate-, NO3-, CIO3-, I-, CNS- (among others). Each series is arranged in order of decreasing ability to: 1) precipitate the dispersed substance of lyophilic soltions; 2) "salt out" organic substances (e.g., aniline, ethyl acetate) from aqueous solutions; or 3) inhibit the swelling of gels. These effects, among other related ones, are ascribable to the abstraction and binding of water by these ions (i.e., hydration), which also decreases in the orders given, so that (in the monovalent cation series) Li+, with the smallest crystal radius, has the largest hydrated radius, and vice versa for Cs+. Synonym: lyotropic series. (05 Mar 2000) |

| homologous series | A series of organic compounds, the succeeding members of which differ from each other by the radical CH2 (as in the fatty series). (05 Mar 2000) |
| series | 1. A number of things or events standing or succeeding in order, and connected by a like relation; sequence; order; course; a succession of things; as, a continuous series of calamitous events. "During some years his life a series of triumphs." (Macaulay) 2. <biology> Any comprehensive group of animals or plants including several subordinate related groups. Sometimes a series includes several classes; sometimes only orders or families; in other cases only species. 3. <mathematics> An indefinite number of terms succeeding one another, each of which is derived from one or more of the preceding by a fixed law, called the law of the series; as, an arithmetical series; a geometrical series. Origin: L. Series, fr. Serere, sertum, to join or bind together; cf. Gr. To fasten, Skr. Sarit thread. Cf. Assert, Desert a solitude, Exert, Insert, Seraglio.

| small bowel series | Radiographic examination of the small intestine following the oral administration of contrast medium, usually barium sulfate. Compare: small bowel enema. (05 Mar 2000) |
| soil series | A group of soils having horizons similar in differentiating characteristics and arrangements in the soil profile, except for texture of the surface layer. (09 Oct 1997) |
| thrombocytic series | The cells of successive stages in thrombocytic (platelet) development in the bone marrow, e.g., thromboblasts, thrombocytes. (05 Mar 2000) |
| erythrocytic series | The cells in the various stages of development in the red bone marrow leading to the formation of the erythrocyte, e.g., erythroblasts, normoblasts, erythrocytes. (05 Mar 2000) |
| type series | <zoology> The series of specimens which either constitutes the name-bearing type of a nominal species or subspecies or from which the name-bearing type has been or may be designated. (09 Jan 1998) |
| fatty series | The alkanes; all the acyclic compounds in the methane, ethane, propane, etc., group, distinguished from the aromatic series. (05 Mar 2000) |
| upper GI series | <investigation, radiology> A series of X-rays of the oesophagus, stomach, and small intestine (upper gastrointestinal, or GI, tract) that are taken after the patient drinks a barium solution. (barium is a white, chalky substance that outlines the organs on the X-ray.) (12 Dec 1998) |
| lower GI series | <investigation, radiology> A radiographic diagnostic procedure that involves the introduction of a barium containing contrast material into the lower gastrointestinal tract via the anus. X-rays taken after instillation of the barium will outline the course and anatomy of the lower GI tract. (27 Sep 1997) |
| lymphoid series | The cells at various states in the development in lymphoid tissue of the mature lymphocytes, e.g., lymphoblasts, young lymphocytes, mature lymphocytes. (05 Mar 2000) |
| lyotropic series | <chemistry> A listing of anions and cations in order of their effect on protein solubility (tendency to cause salting out). Essentially a competition between the protein and the ion for water molecules for hydration. (20 Mar 1998) |
