What's the difference between extraneous and superfluous?

Extraneous


Definition:

  • (a.) Not belonging to, or dependent upon, a thing; without or beyond a thing; not essential or intrinsic; foreign; as, to separate gold from extraneous matter.

Example Sentences:

  • (1) To evaluate threshold estimates under these conditions, computer simulations of experiments with small numbers of trials were performed by using psychometric functions based on a model of two types of noise: stimulus-related noise (affecting slope) and extraneous noise (affecting upper asymptote).

  • (8) The results indicated that FF procedures are easily detected; therefore, difference found between the FF and CF groups may be influenced by extraneous variables.
  • (9) Phoneme identification responses collected in the same experiments, as well as informal observations about the quality of the restored phoneme, suggested that restoration of a fricative phone distinct from the extraneous noise did not occur; rather, the spectrum of the extraneous noise itself influenced phoneme identification.
  • (10) The surface activity of the normally surface-active subtypes, when purified free of extraneous material, was close to those of normal controls.
  • (11) Using buffalo serum, first extraneous proteins were precipitated by making the serum 2.26 M saturated with ammonium sulphate at pH 7.0 and then albumin was precipitated from the supernatant at 1.9 M ammonium sulphate concentration at pH 4.2.

  • (13) The trapped [beta-32P]NANDP X SF1 complex, like the comparable ADP X SF1 complex, was stable for days at 0 degree C and could be purified free of extraneous analogue by ammonium sulfate precipitation and gel filtration.
  • (14) As with the plant ferredoxins the adrenodoxin for these measurements was enriched with (57)Fe by reconstitution of the apo-protein, and subsequently was carefully purified and checked by a number of methods to ensure that it was in the same conformation as the native protein and contained no extraneous iron.
  • (15) The results showed that quality of care seemed to be related more to the orientation and perception of the ward sister than to any number of extraneous variables such as medical and paramedical input, ward facilities and ancillary staff support.
  • (16) Signal is useful variability, potentially relatable to explanatory variables, and noise is extraneous.
  • (17) In particular, studies are needed that employ prospective designs and that deliberately measure or control for the extraneous prognostic variables that may affect adjustment.
  • (18) Then by "phase-switching" on the same cartridge, 1,25(OH)2D is sufficiently resolved from other vitamin D metabolites and extraneous lipophilic compounds to allow its quantification by radioreceptor assay according to an established procedure.
  • (19) The percentage distributions obtained from the CDC data have been adjested to remove the influence of extraneous year-to-year changes in the data.
  • (20) The endogenous mono- and bipolar subtypes of major depressive disorders showed intimate connections between the various neuroendocrine functional systems and the above mentioned extraneous factors resulting in a narrowed variability and a stronger coupling in the reactivity of these hormonal functional systems, a condition which can be seen as analogous to experimental results at the psychophysiological level in these nuclear groups of depressed patients, whose psychopathological state is also characterized by similar limitations in their "degree of freedom" (Heimann).

Superfluous


Definition:

  • (a.) More than is wanted or is sufficient; rendered unnecessary by superabundance; unnecessary; useless; excessive; as, a superfluous price.

Example Sentences:

  • (1) The tetracaine component of TAC is superfluous for obtaining topical anesthesia of minor dermal lacerations of the face in children.
  • (2) If exact indications are present, it can make a surgical intervention superfluous in selected cases.
  • (3) The surgical coordinates of the targets based on the stereotactic CT study with the Stereoadapter were on average as accurate as those obtained with ventriculography; therefore, ventriculography may become superfluous in functional stereotaxis.
  • (4) In many cases, the diagnosis is delayed, often being made only after comprehensive superfluous diagnostic procedures, sometimes invasive, and inappropriate treatment.
  • (5) 62 min Spain make a double substitution: Jesus Navas replaces the superfluous Sergio Busquets, and Fernando Torres replaces the disappointing David Silva.
  • (6) Tell me what will happen when the majority of mankind has become technologically superfluous."
  • (7) It is assumed that the neurotizing agent was the superfluous situational (photic) stimulation which presented excessive requirements to the mechanisms regulating the general functional state of the brain.
  • (8) Seen from the father's point of view, the son, on one hand represents the only solution for continuation of his life, the only possibility of victory over death, on the other hand however, he will substitute him one day, make him superfluous and eventually take his place.
  • (9) Feathering may be considered as a safety margin against spinal cord damage in medulloblastoma but it is superfluous in leukemia.
  • (10) In a later press statement, the Department of Health described the change as "a deep clean of superfluous national targets in favour of clearer, simpler standards".
  • (11) The great advances made in orthopaedic surgery over the last few decades have however not resulted in rehabilitative activity having become superfluous.
  • (12) Among reasons for inadequate numbers of doctors the author mentions in particular superfluous consulting, examinations in conjunction with assessment of the work capacity, and administrative work done by many doctors.
  • (13) Why, they ask, spend scarce public money on something that is both superfluous as a transport link and vastly expensive as a park?
