Example Sentences:

Ytterbium


Definition:

  • (n.) A rare element of the boron group, sometimes associated with yttrium or other related elements, as in euxenite and gadolinite. Symbol Yb; provisional atomic weight 173.2. Cf. Yttrium.

Example Sentences:

  • (1) The displacement of calcium by ytterbium at the EF site has caused a movement in the polypeptide backbone of Ser-91 and Asp-92.

  • (5) Synthetic triclinic calcium pyrophosphate dihydrate crystals were uniformly trace-labeled with Ytterbium-169 (169Yb), a pure gamma-emitting isotope with a halflife of 31 days.
  • (6) Use is made of some new ideas that allow quantification of the likely dose homogeneity that can be obtained in a brachytherapy distribution, and in this context ytterbium 169 is shown to be superior to some currently available brachytherapy nuclides.
  • (7) Nutrient markers were oxides of samarium, scandium, ytterbium, and europium.
  • (8) Ruminal turnover rates of liquid were measured with chromium-ethylenediaminetetraacetate and solid turnover rates with ytterbium-marked fecal fiber, both dosed through the ruminal cannula.
  • (9) The addition of ytterbium to calcium-saturated porcine intestinal calcium-binding protein resulted in the appearance of broad lanthanide-shifted resonances well outside the normally observed region of the 1H nuclear magnetic resonance spectrum of the calcium form of the protein.
  • (10) Samples of duodenal digesta representative of a 24 h period were obtained using chromium-EDTA and ytterbium acetate for flow estimation and 35S as a marker of microbial N entering the small intestine.
  • (11) Similar results were obtained with ytterbium and tungsten in lumbar spine studies.
  • (12) In the present study ovarian blood flow was determined before and after a single intravenous injection of LH to anaesthetized, post-pubertal virgin rabbits, using 15 plus or minus 5 mum microspheres, labelled with Ytterbium-169 and Scandium-46.
  • (13) Isotope studies after injection of Ytterbium 169DTPA into the underlying cyst have shown abnormal patterns in CSF circulation and absorption.

  • (16) Injection of ytterbium-169 as a complex with EDTA or DTPA or injection of Na2Ca EDTA or Na3Ca DTPA 1h after administration of cerium-144 to mothers reduced penetration of both radionuclides into offsprings in relation to the animals receiving no complex compounds.
