What's the difference between erf and kerf?

Erf


Definition:

  • (n.) A garden plot, usually about half an acre.

Example Sentences:

  • (1) The assumption that the distribution of pore sizes is Gaussian has led to the prediction of a linear relationship between the molecular Stokes radius (RS) of the protein and the function erf-1 (1-KD), where KD is the partition coefficient [Ackers (1967) J. Biol.
  • (2) In the present study, neuronal activities of retinal classes R2 and R3 and tectal classes T5(2) and T7 have been extracellularly recorded in response to leading and trailing edges of a 3 degrees X 30 degrees stripe simulating a worm and traversing the centers of their excitatory receptive fields (ERF) horizontally at a constant angular velocity in variable movement direction (temporo-nasal or naso-temporal).
  • (3) No significant difference was also shown in RBF between the control and all ERF-rats studied, through significant decreases in the renal clearance of NMN and renal extraction ratio (ER) were observed in the ERF-rats except the gentamicin-treated rats.
  • (4) The combination of Abc2, Abc1, and Erf also exhibited this activity.
  • (5) Overall cosmetic results were also better for the TRAM without implant than for the ERF (72% good vs. 51%).
  • (6) The accessory recombination function (arf) gene of bacteriophage P22 is located immediately upstream of the essential recombination function (erf) gene.
  • (7) After 1,25(OH)2D therapy a significant increase in serum phosphate, urinary calcium, and a decrease in urinary cAMP is observed only in ERF patients.
  • (8) However, Erf was inactive, both by itself and in combination with Abc1; Abc2 had weak activity.
  • (9) The red rod-mediated ERFs seem to be somewhat larger than the cone-mediated but smaller than the green rod-mediated.
  • (10) Greg Hunt spent his time in Paris continuing to pretend that his emissions reduction fund (ERF) is a carbon price and also an idea being adopted around the word, but the experts, when asked , said reverse auctions like the ERF were useful additions to a carbon price, but not a good primary policy to drive down greenhouse emissions.
  • (11) However, despite the smallest RFR, SK patients with ERF had the highest percentage increase in their GFR.
  • (12) Ten upper rectus (ERF) and 42 lower rectus (TRAM) were the two procedures applied.
  • (13) Nevertheless, the FMLC technique has been found to be a valid and useful technique particularly in the study of serum ERF titers.
  • (14) All three receptor types contribute to the IRF surrounding the ERF of classes 1, 2, 3 and deviating class 4 cells.
  • (15) Microsomal benzphetamine N-demethylase (BND) and 7-ethoxyresorufin O-deethylation (ERF) activities, catalyzed by P-450 isozymes 2 and 6, respectively, and specific P-450 content were determined after incubation with ABT.
  • (16) A correlation was noted between the magnitude of bronchial secretion viscosity and some characteristics: intensity of asphyxia attacks, dyspnea, number of dry rales; bronchial patency according to the ERF estimates.
  • (17) The pathophysiological consequence of such a deficiency in patients with ERF may be important.
  • (18) The nucleotide sequence of a segment of the bacteriophage P22 chromosome to the left (downstream in the PL operon) of the erf gene was determined.
  • (19) No significant difference was shown between the values of RBF determined by the NMN method and conventional p-aminohippurate (PAH) method in both the intact (control) and glycerol-ERF rats, suggesting the usefulness of the NMN method in determining RBF.
  • (20) On the basis of literature analysis and clinical experience, a classification of external respiratory failure (ERF) is suggested.

Kerf


Definition:

  • (n.) A notch, channel, or slit made in any material by cutting or sawing.

Example Sentences:

  • (1) In children older than 1, however, the bone is relatively brittle, yet it, too, may be remodeled by sectioning it first into 1.5 to 2.0 cm wide strips, then placing resistance-weakening kerfs on the bone's endocranial surface.
  • (2) The kerfs weaken the bone regionally so that controlled bending may occur.
