What's the difference between inoperative and nugatory?

Inoperative


Definition:

  • (a.) Not operative; not active; producing no effects; as, laws renderd inoperative by neglect; inoperative remedies or processes.

Example Sentences:

  • (1) Subjects were 56 therapies for HCCs in 48 cases, who were diagnosed as inoperative HCCs, and were performed chemotherapy, transcatheter hepatic arterial embolization (TAE) and percutaneous ethanol injection therapy (PEIT).
  • (2) Filamentation continued in dif mutants in which SOS-associated division inhibitors were inoperative, which showed that induction of these inhibitors was not the primary cause of filamentation.
  • (3) If this pressure persisted until the start of the expansion, it would make the opercular suction pump inoperative, because it would blow away the flexible opercular flap which, as a passive valve, seals the widening opercular slit during abduction.
  • (4) We investigated the incidence and endoscopic features of gastroduodenal lesions which appeared after transcatheter arterial chemo-embolization (TACE), performed 29 times in 25 patients with inoperative hepatocellular carcinoma.
  • (5) We suggest macrophages may absorb, and thus render inoperative, factors which are necessary for lymphocyte cooperation.
  • (6) The competitive pattern of this inhibition leads to its being inoperative in ornithine-grown cells, where the intracellular concentration of ornithine is high.
  • (7) For example, in excised patches of vertebrate rod outer segment plasma membrane, the cGMP-activated cation channels have traditionally been studied in room light because the enzyme cascade linking photon absorption to channel closure was assumed to be inoperative.
  • (8) Negative feedback of gonadal steroids seems to be inoperative.
  • (9) Duck erythrocytes treated with norepinephrine in a solution containing 15 mM K+ swell to a new stable cell volume after 60 min, during which time cotransport becomes inoperative.
  • (10) Such results, obtained from birds in which testosterone feedback was inoperative, indicate that the gonadostimulatory effect of long daylengths in intact males must be mediated, at least in part, by an androgen feedback-independent mechanism.
  • (11) Induction of recA or polA1 cells by nalidixic acid does not result in the appearance of pol I*, but lexA or recA mutants that are constitutive for SOS functions constitutively express pol I* and mutants which lack functional recA protein produce pol I* when they carry a lexA mutation which renders the lexA repressor inoperative.
  • (12) Indication of this therapy has been fundamentally limited to the inoperative cases in which patient performance status has deteriorated.
  • (13) Hence, regulatory mechanisms, inoperative in vitro, probably function in vivo to prevent immune activation of self-recognizing lymphocytes and autoimmunity.
  • (14) We suggest as an explanation that the majority of daughter strand gap-filling is error free and that mutations arise through a minor error-prone repair pathway which is inoperative under these conditions.
  • (15) Previous studies demonstrated that hen erythrocytes have an inoperative, latent sphingomyelinase which is activated when the cells are hemolyzed in a hypotonic medium.
  • (16) It is concluded that the epsilon proofreading subunit of DNA polymerase III holoenzyme is excluded, inhibited, or inoperative during misincorporation and mutagenesis after UV.
  • (17) One-hundred and eleven species and three species varieties belonging to 39 genera were collected from 50 dust samples on the five media used at 28 degrees C. Using the hair-baiting technique with horse hair, 10 species of Chrysosporium were isolated: C. asperatum, C. state of Arthroderma tuberculatum, C. indicum, C. inops, C. keratinophilum, C. merdarium, C. pannorum, C. queenslandicum, C. tropicum and C. xerophilum.
  • (18) In such cells the PGK step presumably was inoperative due to total lack of substrate; 2,3-diphosphoglycerate (2,3-DPG) then became the sole substrate source for remaining steps in glycolysis.
  • (19) This is due to two mutations, one inactivating ATP-driven sodium transport and a second rendering NaH-antiport inoperative.
  • (20) First, as with the measurements of pulmonary function (Chapter 12), the initial lack of training in adequate maintenance was responsible for inoperative instruments.

Nugatory


Definition:

  • (a.) Trifling; vain; futile; insignificant.
  • (a.) Of no force; inoperative; ineffectual.

Example Sentences:

  • (1) The third facet of the problem is concern that Draghi’s intervention will be too little, too late, and that Europe is condemned to years of nugatory growth.
