Thus, samples with dispersed clay microstructure were prepared by boiling mixtures with 25 ml of a dispersant--4% sodium pyrophosphate tetrabasic, which separates existing clay aggregates into individual clay platelets and their smaller associations.

About 80-100 mg of adipose tissues was homogenized using a PowerGen Model 500 homogenizer (Fisher Scientific, Pittsburgh, Pennsylvania) in radioimmunoprecipitation assay (RIPA) buffer (25mmol/L Tris HCl, 10 mmol/L sodium orthovanadate, 100 mmol/L sodium fluoride, 50 mmol/L sodium pyrophosphate tetrabasic, 10 mmol/L ethylene glycol tetraacetic acid (EGTA), 10 mmol/L ethylenediaminetetraacetic acid (EDTA), and 1% IGEPAL) with protease inhibitors.
Five papers from the Shaanxi University of Science and Technology investigate the effect of the chemical structure and sodium sulfate on polycarboxylate superplasticizers in cement pastes, a degraded chitosan for retanning leather, and a tetrabasic graft copolymer adhesive.
Zinc oxide is the most widely studied source of zinc used in studies on weaning pigs, however there are indications that other zinc sources can substitute this additive at the same concentration (tetrabasic zinc chloride, Mavromichalis et al., 2001), while various zinc organic sources fed between 300 and 500 mg Zn/kg increased (Buff et al., 2005) or did not increase (Hollis et al., 2005) growth as did ZnO at 2,000 mg Zn/kg.

Although only a few stretches of amino acid sequence are common to the precursors of these two species [i.e., a single copy of FLRFamide, a sequence SEEPLYRKRRS which includes a tetrabasic proteolytic processing site, and the multiple copies of FMRFamide], the general organization of these two precursors is similar (see Greenberg and Price, 1992).
ABSTRACT : An experiment was conducted to investigate the mechanism for the effect of tetrabasic zinc chloride (TBZC) in enhancing growth performance of weanling piglets.
