| periodic system | The arrangement of the chemical elements in a definite order as indicated by their respective atomic numbers in such a way that groups of elements with similar chemical properties (similar valence shell electron number) are grouped together. See: Mendeleeff's law. (05 Mar 2000) |
| periodical | 1. Of or pertaining to a period or periods, or to division by periods. "The periodicaltimes of all the satellites." (Sir J. Herschel) 2. Performed in a period, or regular revolution; proceeding in a series of successive circuits; as, the periodical motion of the planets round the sun. 3. Happening, by revolution, at a stated time; returning regularly, after a certain period of time; acting, happening, or appearing, at fixed intervals; recurring; as, periodical epidemics. "The periodic return of a plant's flowering." (Henslow) "To influence opinion through the periodical press." (Courthope) 4. Of or pertaining to a period; constituting a complete sentence. Periodic comet, the generalisation that the properties of the chemical elements are periodic functions of their atomic wieghts. "In other words, if the elements are grouped in the order of their atomic weights, it will be found that nearly the same properties recur periodically throughout the entire series." The arrangement of the atomic weights shows the regular recurrence of groups, each consisting of members of the same natural family. A similar relation had been enunciated in a crude way by Newlands; but the law in its effective form was developed and elaborated by Mendelejeff, whence it is sometimes called Mendelejeff's law. Important extensions of it were also made by L. Meyer. By this means Mendelejeff predicted with remarkable accuracy the hypothetical elements ekaboron, ekaluminium, and ekasilicon, afterwards discovered and named respectively scandium, gallium, and germanium. <astronomy> Periodic star, the time of a complete revolution of the body about the sun, or of a satellite about its primary.

| periodical index | Useful as a subject approach to the contents of a periodical issuing an annual, biennial, quinquennial, decennial, etc., index. The heading is used for the overall body of articles published by a periodical in the same sense that bibliography is useful when published as a single article. (12 Dec 1998) |
| periodicals | A publication issued at stated, more or less regular, intervals. (12 Dec 1998) |
| periodicity | The quality or state of being periodical, or regularly recurrent; as, the periodicity in the vital phenomena of plants. Origin: Cf. F. Periodicite. Source: Websters Dictionary (01 Mar 1998) |
| periodontal | <dentistry> Pertaining to your gums. For example periodontal disease is gum disease. (08 Jan 1998) |
| periodontal abscess | Localised circumscribed purulent area of inflammation in the periodontal tissue. It is a derivative of marginal periodontitis and commonly associated with suprabony and infrabony pockets and interradicular involvements, in contrast to periapical abscess which is attributable to pulp necrosis. (12 Dec 1998) |
| periodontal anaesthesia | Anaesthesia of the periodontal ligament, produced by injection of a local anaesthetic drug. (05 Mar 2000) |
| periodontal atrophy | Decrease in size and/or cellular elements of the periodontium after it has reached normal maturity. (05 Mar 2000) |
| periodontal attachment loss | Loss or destruction of periodontal tissue caused by periodontitis or other destructive periodontal diseases or by injury during instrumentation. Attachment refers to the periodontal ligament which attaches to the alveolar bone. It has been hypothesised that treatment of the underlying periodontal disease and the seeding of periodontal ligament cells enable the creating of new attachment. (12 Dec 1998) |
| crisis period | A situation in which most of the secondary cells in a culture die off, even though conditions exist which should normally be favorable for their growth. (09 Oct 1997) |

| hamilton period | <geology> A subdivision of the Devonian system of America; so named from Hamilton, Madison Co, new York. It includes the Marcellus, Hamilton, and Genesee epochs or groups. Source: Websters Dictionary (01 Mar 1998) |
| preejection period | The interval between onset of QRS complex and cardiac ejection; electromechanical systole minus ejection time. (05 Mar 2000) |
| prepatent period | <microbiology> The period of time equivalent to the incubation period of parasite infections compared with microbial infections. It is biologically different, because the parasite is undergoing developmental stages in the host, and the prepatent period represents the time from infection until a female starts to produce eggs, and is equivalent to the latent period in microparasitic infections. (21 Jun 2000) |
| salina period | <geology> The period in which the American Upper Silurian system, containing the brine-producing rocks of central new York, was formed. Origin: So called from Salina, a town in New York. Source: Websters Dictionary (01 Mar 1998) |
| prodromal period | The time during which a disease process has begun but is not yet clinically manifest. (05 Mar 2000) |
| puerperal period | The period elapsing between the termination of labour and the return of the generative tract to its normal condition; the 6 weeks following the completion of labour. (05 Mar 2000) |
| pulse period | The reciprocal of the repetition rate; e.g., the interval between leading edges of successive pulses. (05 Mar 2000) |
| silent period | The time during which there is no electrical activity in a muscle following its rapid unloading, any pause in an otherwise continuous series of electrophysiologic events. (05 Mar 2000) |
| niagara period | <geology> A subdivision or the American Upper Silurian system, embracing the Medina, Clinton, and Niagara epoch. The rocks of the Niagara epoch, mostly limestones, are extensively distributed, and at Niagara Falls consist of about eighty feet of shale supporting a greater thickness of limestone, which is gradually undermined by the removal of the shale. See Chart of Geology. Source: Websters Dictionary (01 Mar 1998) |
