Hypochlorous acid (HOCl) solutions were evaluated for their virucidal ability against a low pathogenic avian influenza virus (AIV), H7N1. HOCl solutions containing 50, 100 and 200 ppm chlorine (pH 6) or their sprayed solutions (harvested in dishes placed at 1 or 30 cm distance between the spray nozzle and dish) were mixed with the virus with or without organic materials (5% fetal bovine serum: ...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...

the study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and na+, mg2+, ca2+ uptake of pistachio seedling (akbari) grown under salt stress.  a completely randomized design was used with four replications in greenhouse conditions. the experimental treatment consisted of four levels of humic acid (bis humic) (0, 4, 8 and 12 gr k...

We investigated the effects of turbidity and concentration of humic acid on the steady-state behavior of the blanket, which was coagulated using polyaluminum chloride (PACl) as coagulant. The three-dimensional solid-flux plot was constructed. Based on fixed PACl dosage, the iso-humic-acid solid-flux surfaces stacked that enveloped the feasible regime for the blanket bed. The steady-state point ...

In recent years, excessive use of chemical fertilizers and lack of organic fertilizers caused to reduce the rate of soil organic matter in Iran. The increased use of chemical fertilizers in agriculture causes environmental problems such as soil physical degradation and soil nutrient imbalances. This study was conducted to investigate the effects of foliar and soil applications of humic acid on ...

The effects of humic acid on poliovirus type 1 recovery from water by Zeta Plus 60S filters were investigated. The humic acid interfered by preventing virus adsorption to the filters, and the interference increased as a function of the amount of humic acid filtered. Humic acid decreased virus adsorption when filtered before the virus, but did not elute virus which had adsorbed to the filters. T...

one of the strategies for improving the quality of agricultural products is using bio-fertilizers. so in order to study the effects of mycorrhizal fungi, vermicompost and humic acid on growth characteristics and yield of fennel, an experiment was studied on research farm of agricultural college of shahrood university. this study was conducted as factorial experiment based on completely randomiz...
