Manifold


Definition:

  • (a.) Various in kind or quality; many in number; numerous; multiplied; complicated.
  • (a.) Exhibited at divers times or in various ways; -- used to qualify nouns in the singular number.
  • (n.) A copy of a writing made by the manifold process.
  • (n.) A cylindrical pipe fitting, having a number of lateral outlets, for connecting one pipe with several others.
  • (n.) The third stomach of a ruminant animal.
  • (v. t.) To take copies of by the process of manifold writing; as, to manifold a letter.

Example Sentences:

  • (1) Combined hypertension treatment with inhibitors of the converting enzyme (ICE) and diuretocs gives manifold advantages, the most important of them is a synergistic action of both drugs resulting in blood pressure decrease and prevention of hypokaliaemia.
  • (2) It is stressed that the exact anatomical diagnosis requires the examination of every segment which can be performed only by using manifold planes.
  • (3) An anaerobic sampling manifold withdrew 19 samples of blood during the rest-to-exercise transition; sampling interval was usually 4 s. Blood gas analysis showed that, on average, from rest-to-steady-state exercise, O2 saturation (Svo2) fell from 71 to 41% and mixed venous PCO2 (PvCO2) rose from 42 to 59 Torr.
  • (4) These induction periods are regarded as the time needed by far-from-equilibrium fluctuations to drive the system into the center manifold.
  • (5) The apparent Km of the modified enzyme for soluble starch increased manifold, thus implicating the sensitive tryptophan residue in the substrate binding region of the enzyme.
  • (6) All image vectors were orthonormalized to span a linear manifold.
  • (7) A manifold for rapid determination of fluoride has been designed that uses a single coil for complex formation and extraction.
  • (8) Impinger samples were collected from the sampling manifold and analyzed accordingly.
  • (9) This manifold can be used to validate or calibrate various industrial hygiene analyses such as charcoal and detector tube technology, impinger techniques, respirator cartridge testing, and various survey instruments.
  • (10) The presentation of SAS may be manifold, and the primary health care teams play a crucial role in the detection of their basic symptoms.
  • (11) The modification can be made in less than 4 h without the need for any additional parts; the modified manifold requires one-third fewer pump lines and fewer reagents, thus reducing operating costs and simplifying instrument maintenance, while retaining the same precision, speed, low carryover, and linearity of the production model.
  • (12) The low-field temperature dependence of the MCD of oxidized FdI, which originates in the paramagnetic oxidized [3Fe-4S]1+ cluster, establishes the absence of a significant population of excited electronic states of this cluster up to 60 K. The low-field temperature dependence of the MCD of reduced FdI establishes that the ground-state manifold of the reduced [3Fe-4S]0 cluster possesses S greater than or equal to 2 at both pH 6.0 and 8.3.
  • (13) The appearance of this disease as generalized vasculitis is conditioned by the manifold clinical symptomatology and thus renders the diagnostics extraordinarily difficult.
  • (14) After certain modifications had been made in the manifold, satisfactory degrees of accuracy were also obtained for the erythrocyte counts.
  • (15) Among the manifold immunologic events which take place during parasitic invasions, production of autoantibodies and immune complexes can play a serious role during infections with African and American trypanosomes.
  • (16) There are manifold specific causes of death characterized by conditions manifest in middle and late life.
  • (17) It is now customary practice to couple separately metered infusions via a manifold to a common catheter that enters the patient.
  • (18) The differential diagnoses was manifold because of the traveling habits, the clinical symptomatic and the course of the disease.
  • (19) Their information must be transduced through binding to membrane receptors, so as to elicit the appropriate biological response from the manifold repertoire of a cell.
  • (20) The enzyme can be seen as strategically located to play a role in regenerating ATP required for the manifold activities of the synaptic membrane.

Once


Definition:

  • (adv.) By limitation to the number one; for one time; not twice nor any number of times more than one.
  • (adv.) At some one period of time; -- used indefinitely.
  • (adv.) At any one time; -- often nearly equivalent to ever, if ever, or whenever; as, once kindled, it may not be quenched.
