Six isolates of Botrytis cinerea were isolated from leaves and stems of different tomato varieties taken from four areas in the northwest of Algeria where tomato is mostly grown in greenhouses and high tunnels. The purpose of this research was to determine the effect of two salts, NaCl and CaCl2, on three stages of Botrytis cinerea's life cycle. All isolates tested were stimulated in 50 to 150 ...

Effects of a wide range of concentrations of four salts (NaCl, KCl, MgCl2, CaCl2) on cell proliferation were investigated in suspension culture of a mangrove plant, Sonneratia alba. The results were compared to those obtained with suspension culture of another mangrove species, Bruguiera sexangula and non-mangrove tobacco BY-2 cells. Effects of salts on suspension cells were determined with bot...

In this paper, chitosan was grafted with acrylic acid and positively charged elements, a series of reinforced nanofiltration membranes were prepared by coating modified polymer polysulfone ultrafiltration membrane as support. The structure derivatives polymers characterized infrared spectrum, the scanning electron microscope atomic force microscope. performance composite closely related to elec...

The paper presents results of the study electrochemical reduction tungsten(VI) oxide in a melt eutectic composition 52 mol% CaCl2 and 48 NaCl at liquid gallium electrode. Scanning electron microscopy X-ray diffraction methods were used to microstructures obtained powders. Rietveld method which is based on patterns calculate quantitative content phases WO3 products. thermodynamic properties elec...

The interaction of tungsten (VI) oxide and calcium tungstate with a molten eutectic mixture calcium-sodium chlorides in the temperature range from 600 to 800 °С was investigated by methods isothermal saturation, mass spectrometry inductively coupled plasma (ICP–MS) X-ray phase analysis. It noted that solubility both trioxide depends large extent on temperature. Thus, 700 °C, equilibrium concent...
