The H NMR relaxometry in combination with water proton spin–spin relaxation time measurements and rheometry have been applied to study the ionic gelation of 1% w/w aqueous low methoxyl pectin solution induced by divalent Ca cations from a calcium chloride solution. The model-free approach to the analysis of H NMR relaxometry data has been used to separate the information on the static (β) and d...

the tuberose cut flower is much less longevity in postharvest. the less vase life due to stress of deficit carbohydrate and quick respiration on inflorescence. in this study, effectiveness factors, sucrose, cacl2, al2so4 and re-cut the stems. in current research two separate experiments were arranged as a factorial based on compeletly randomized design. the first experiment were added to all ex...

The present study investigated the antiarrhythmic activity of alcoholic extract of Tinospora cordifolia (T. cordifolia) in CaCl2 induced arrhythmia. CaCl2 (25 mg/kg) was administered by intravenous infusion (iv) to produce arrhythmia in rats. The animals were then treated with T. cordifolia extract (150, 250, and 450 mg/kg) and verapamil (5 mg/kg,iv). Lead II electrocardiogram was monitored. Pl...

in order to study the effects of ga3and cacl2 treatments in resolve the problems of sweet pepper culture in ilam region (including small size fruits with sunscald and blossom end rot disorders), this study was carried out in ilam university in 2012. for that, ga3 (50 mg/l) and cacl2 (0.5%) treatments were sprayed at two (fruit set and 15 days thereafter) and three (fruit set, 10 and 20 days the...

Biocemented Martian regolith simulant (MRS) columns were developed using a microalga, Thraustochytrium striatum. Response surface methodology was used to maximize the unconfined compressive strength (UCS) of biocemented MRS towards particle size, cell biomass loading, and nutrient (CaCl2/urea) loading. Overall, UCS increased with increase loading while medium size achieved highest UCS. But didn...

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 anti...

The SiO2-CaCl2 hybrid porous materials were prepared by the sol-gel method. This process was conducted by the hydrolysis and condensation of Tetraethyl orthosilicate (TEOS) by replacement of ethanol from alcogel and drying at the ambient temperature to obtain xerogel structure. The alcogel samples were synthesized from TEOS, EtOH, H2O, HCl, NH4OH and CaCl2, while the total molar ratio of the co...
