In this study, effect of salinity with different osmotic potential on shoot length, total fresh and dry weight, amounts of organic (proline) and inorganic (K+ and Na+) substance of leaf tissue, the Na+/K+ ratio, and leaf area, relative water content (RWC) and leaf osmolality in two maize (Zea mays L., var. intendata, C.6127 and DK.623) cultivars which are grown as a second yield in the Southeas...
Concentrated CaCl2 and CaBr2 salt solutions of densities up to 2.3 kg L-1 are regularly used to control hydrostatic pressure in oil wells during special operations in the exploration and production of natural gas and crude oil. Various concentrations of high density salts are frequently left in mud pits near the drilling site as waste, polluting fresh and ground waters by spillage and drainage....
Ensifer medicae strain WSM1115 forms effective nitrogen fixing symbioses with a range of annual Medicago species and is used in commercial inoculants in Australia. WSM1115 is an aerobic, motile, Gram-negative, non-spore-forming rod. It was isolated from a nodule recovered from the root of burr medic (Medicago polymorpha) collected on the Greek Island of Samothraki. WSM1115 has a broad host rang...
Using response surface methodology (RSM), this study investigates the effect of NaCl substitution (50%) with KCl, CaCl2, and MgCl2 in packaging brines (controlled variables) on characteristics (responses) plain green Spanish-style Manzanilla olives, maintaining salt-mixture level 5%. The RSM showed that increment CaCl2 caused a linear significant (p-value ≤ 0.05) decrease pH increase firmness (...
An existing idle cooling tower can be reversibly used as a heat-source tower (HST) to drive a heat pump (HP) in cold seasons, with calcium chloride (CaCl2) aqueous solution commonly selected as the secondary working fluid in an indirect system due to its good thermo-physical properties. This study analyzed the effect of CaCl2 mass fraction on the effectiveness (ε) of a closed HST and the coeffi...
The cement industry is carbon-intensive, and the valorisation of industrial side-streams/residuals for use as alternative raw materials can enable to reduce its carbon footprint well promote resource efficiency. Apart from key clinker ingredients such CaO, Al2O3, SiO2, residues also contain MgO, CaCl2, SO3. Therefore, this study investigates formation assemblages in system CaO-SiO2-Al2O3-SO3-Ca...
During last two decades, polysaccharides such as alginate (Alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. The aim of the present work was to investigate the potential utility of microparticles made of alginate (Alg) as new vehicles for improving nasal vaccine delivery. For this purpose, diphtheria toxoid (DT) was chosen as a model an...
The self-assembly of anionic kappa and iota carrageenan polysaccharides in the presence of NaCl, KCl and CaCl2 is studied by high-resolution atomic force microscopy (AFM). A hierarchical supramolecular chirality amplification over various length scales is observed upon the addition of KCl, whereas in the presence of NaCl and CaCl2 the chains undergo solely a coil-helix transition with stiff kap...
