Remarks onMarsilea macropus,(the Nardoo Plant,) which had germinated in the Edinburgh Botanic Garden
EDTA can complex with radionuclides (RNs) to form negatively charged complexes, making it difficult for clay minerals retard the diffusion of RNs waste. The coefficient in water ( D w ) is an important parameter safety assessment repository. In this study, effectsof on metal ions (Cu 2+ , Sm 3+ Nd Lu and Zn were investigated by a capillary method. experimental results showed that [Cu-EDTA] 2- [...
OBJECTIVE This study aims to compare the clot stabilization on root surfaces conditioned with citric acid and ethylenediamine-tetraacetic acid (EDTA). MATERIALS AND METHODS Scaled root samples (n = 100) were set in fve groups: group I-control group (saline solution); group II (24% EDTA); group III (25% citric acid); group IV (EDTA + citric acid); group V (citric acid + EDTA). Fifty samples we...
Ethylenediaminetetraacetic acid (EDTA) is widely used in the life sciences as chelating ligand of metal ions. However, formation of supramolecular EDTA aggregates at pH > 8 has been reported, which may lead to artifactual assay results. When applied as a buffer component at pH ≈ 10 in differential scanning fluorimetry (TSA) using SYPRO Orange as fluorescent dye, we observed a sharp change in fl...
Epithelial cells of the toad bladder were disaggregated with EDTA, trypsin, hyaluronidase, or collagenase and were then scraped free of the underlying connective tissue. In most experiments EDTA was complexed with a divalent cation before the tissue was scraped. Q(OO2), sucrose and inulin spaces, and electrolytes of the isolated cells were measured. Cells disaggregated by collagenase or hyaluro...
The trior tetrasodium salt of ethylenediaminetetraacetic acid (EDTA or Na EDTA) is a strong chelating agent for heavy metals and the alkaline earth metals, calcium and magnesium. By this action the activity of enzymes which are known to be influenced by calcium or magnesium is altered by the addition of EDTA; e.g., muscle adenylate kinase, which is accelerated by magnesium, is completely inacti...
from historical facts to geo-political realities: relation between turkey and armenia ( 1915 – 2010)
armenias geopolitics and its historical experience have had a determining impact on the character of its foreign policy .present-day armenia is a small, landlocked country with _11,620 square miles area armenias landlocked nature makes it dependent on the benevolence of its neighbors for access to the outside world a fact that gives it a sense of isolation and vulnerability. as it was indic...
