In a previous study (6) the influence of high osmotic concentrations of sodium salts and nutrient solutions upon the vegetative development of the tomato was reported, hut no data were obtained on the fruiting responses. To investigate this problem, to obtain further information on the relative toxicity of the Cland SO,= ions, and the effect of osmotic concentration, experiments were set up to ...

Geopolymer is an inorganic form of alumina-silica that synthesized through materials containing lots silica (Si) and alumina (Al) originating from nature or industrial by-products. The geopolymer binder a two-component system consisting solid components have sufficient amounts SiO2 Al2O3 to compounds such as fly ash, rice straw pozzolan, laterite soil, slag, etc. This study aims analyze the com...

In this study, two capillary electrophoresis modes, capillary zone electrophoresis (CZE) and micellar electrokinetic chromatography (MEKC), were employed for the examination of gel ink fingerprints. The optimized CZE conditions were as follows: running buffer, 0.2M boric acid and 0.05M sodium tetraborate; pH, 6.47; detection, 214 nm; separation voltage, 20 kV MEKC conditions were as follows: 20...

the binding of sodium n-dodecyl sulphate (sds) to aspergillus niger catalase in various ionic strengths at ph 6.4 and a temperature of 27? and 37?c has been studied over a range of sds concentrations using equilibrium dialysis and fluorescence spectroscopy techniques. the binding data were used and interpreted in terms of theoretical models (scatchard equation and wyman binding potential). the ...

In the manuscript main factors that affect thermal mass of open and closed types heat storage devices are shown. Also, requirements for adsorption modules given. The calculation procedure has been refined, which includes determination load, adsorption, adsorbent mass, as well integral, structural, specific mass. masses heat-accumulating were evaluated. affecting their value analysed. It is show...

H]glucosamine has been used to label metabolically keratinocyte cell-surface glycoconjugates. The major labelled bands identified on sodium dodecyl sulphate/polyacrylamide gels had apparent molecular weights of greater than 250000, and 150000-80000. Most of these components were trypsin-sensitive, indicating that the label was protein-bound. Some of the labelled components were shown to be prot...

nanocrystalline zinc oxide (zno) powders with different morphology have been successfully synthesized by using different surfactants such as cetyl trimethyl ammonium bromide (ctab), sodium dodecyl sulphate (sds), and tri ethanol amine (tea) via hydrothermal method. the products were characterized by means of powder x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electr...
