Lecithin and lecithin/cholesterol dispersions as well as lysolecithin micelles were used to provide basic information on the mechanism of the interaction of zwitterionic phospholipids with dextran sulfate. The addition of dextran sulfate to lecithin dispersions or lysolecithin micelles in the presence of Ca2+ produced insoluble complexes. At each Ca2+ concentration, the amount of insoluble comp...

THE EFFECT OF REVERSE FLOTATION METHOD ON SILICA SAND AS WATERPROOFING MORTAR. Waterproof fabrication mortar cement by silica sand using reverse flotation (RFS) method was evaluated waterproof absorption coefficient, compressive strength test, attractive and contact angle. RFS is used to replace agent aggregate reduce cost. The aims of this experiment are know the process, ratio between with mo...

This study aimed to synthesize and characterize calcium oxide (CaO) nanoparticles as a photocatalyst in the degradation process of indigo carmine (IC) dyes. Several steps were carried out produce CaO by mixing 0.5 M CaCl2 solution with various NaOH solutions (0.5; 0.8; 1.0 M). Experimental results showed prospective control particle sizes. The experiments also confirmed that greater concentrati...

Background: Purple coneflower (Echinacea purpurea L.) is one of the most important medicinal plants. Hairy root culture of Echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites. Objective: The present study investigates the effects of KNO3, CaCl2 and MgSO4 concentrations on growth and the biosynthesis of cichoric acid in Echinacea...

this experiment was conducted in germinator in order to study the effects of water potential on seed germination, rate of germination and seedlings growth of four medicinal plants (coriandrum sativum, plantago psyllium, discorinia sophia and portulaca oleracea). four water potential inclouding distilled water as control (0), -0.37, -0.59 and –0.81 mpa which made by different salts (nacl, cacl2 ...

Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...

Preharvest calcium application has been shown to increase broccoli microgreen yield and extend shelf life. In this study, we investigated the effect of calcium application on its metabolome using ultra-high-performance liquid chromatography with mass spectrometry. The data collected were analyzed using principal component analysis and orthogonal projection to latent structural discriminate anal...

Herein we demonstrated the effect of oxygen and air atmosphere on the success of short-term storage of sperm obtained from rainbow trout (Oncorhynchus mykiss), sterlet (Acipenser ruthenus) and common carp (Cyprinus carpio) diluted in immobilizing media (100 mM NaCl, 40 mM KCl, 3 mM CaCl2, 1.5 mM MgCl2, 50mM Tris, pH 8.2 for salmonid fish, 17 mM NaCl, 1.7 mM KCl, 6 mM NaHCO3, 0.5 mM CaCl2, 0.5 m...
