Five cycles of germination NaC1 tolerant alfalfa and the source population, 'Mesa Sirsa', were germinated in four salt solutions (NaC1, NaNO3, KC1, and KNO3) and Mannitol to try to determine the general mechanism involved in seed germination salt tolerance. Average germination over all germplasm sources in NaC1, NaNO3, KC1, KNO3, and Mannitol were 44.80, 38.88, 36.24, 29.07, and 60.93 percent, ...

Stability constant (log ) and thermodynamic parameters of Cd complexes with sulfonamide and cephapirin were determined by Polarographic technique at pH = 7.30 ± 0.01 and μ = 1.0 M KNO3 at 250°C. The sulfonamides were sulfadiazine, sulfisoxazole, sulfamethaxazole, sulfamethazine, sulfathiazole, sulfacetamide and sulfanilamide used as primary ligands and cephapirin as secondary ligand. Cd formed ...

We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...

OBJECTIVE This research systematically evaluated the use of a clinically proven desensitizing dentifrice prior to a bleaching regimen in a randomized, multi-center, parallel group, open label clinical study following Good Clinical Practice guidelines. METHODOLOGY Fourteen dental offices in West Palm Beach, Florida participated in the study during April/May 2004. Fourteen days prior to bleachi...

Soybean cell suspension cultures grew on defined media with ammonium as the sole nitrogen source if Krebs cycle acids were added. Satisfactory growth was obtained with ammonium salts of citrate, malate, fumarate, or succinate, when compared with the regular medium containing nitrate and ammonium. Little or no growth occurred when ammonium salts of shikimate, tartrate, acetate, carbonate, or sul...

Olive mill wastewaters (OMW) are a by-product from olive oil manufacture that cause environmental pollution. These wastes have been used as substrate for the production of the extracellular polysaccharide xanthan by Xanthomonas campestris NRRL 31459-S4L41. Growth and xanthan production on dilute OMW as a sole source of nutrients were obtained at OMW concentrations below 60%, yielding a maxima1 ...

To break dormancy and increase the germination of Prunus avium L. (mazzard cherry) seeds, various methods were tested including the removal of the seed coat after cold moist stratification and treatment with GA3, KNO3, or thiourea. Treatments with 7,500 ppm KNO3 after 120 days of stratification were more effective, yielding 64.54% germination of seeds with coat. In seeds without coat, 500 ppm G...

Thermal energy storage (TES) based on molten salts has been identified as a key player in the transition from fossil fuels to renewable sources. Solar Salt, mixture of NaNO3 (60 wt%) and KNO3 (40 wt%), is currently most advanced heat transfer material used concentrating solar power (CSP) plants. Here, it utilized produce electricity via Rankine cycle, with steam temperatures reaching 550 °C. Th...
