abstract in this experiment the effects of two type of medium cultures, gibberellic acid and dark/cold and light/warm culture conditions on mature embryos germination of a local cultivar of walnut were investigated. the mature fruits were collected at 22 weeks postanthesis and after disinfection the mature embryo along with cotyledon pieces were excised and then were cultured on mt and modified...

The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...

in the present study, silver oxyfluoride modified silver electrode was employed to electrocatalytic oxidation of isoniazid. the process of oxidation and its kinetics were established by using cyclic voltammetry, chronoamperometry and amperometry techniques. the modified electrode shows a stable and linear response in the concentration range of 3×10−4 to 2.1×10−3 mol l-1 with a correlation coeff...

The aim of this work was to study the allelopathic effect of 3 extracts viz 3%,5% and 10% prepared from leaves of GM (insect resistance) and non GM maize on physiology of succeeding crop wheat (Triticum aestivum L.). The extracts prepared from GM maize significantly decreased chlorophyll a content but significantly increased chlorophyll b content as compared with untreated control. Content of c...

Laccase activity and stability were improved and modified through the interaction between laccase amino acid residues (e.g., amino groups (NH2) and carboxyl groups (-COOH)) and the chemical reagents thiourea dioxide (TDO) and L-phenylalanine methyl ester hydrochloride (L-PME). Compared with the control sample, the activity of the laccase modified with these chemical reagents was increased by 20...
