Impact of osmotic stress on seedling growth observations, membrane characteristics and antioxidant defense system of different wheat genotypes
The objective of the present study was to find out a straightforward technique for screening the tolerance of ten wheat genotypes to two levels of osmotic stress at early seedling stage. Data revealed that polyethylene glycol-induced drought had general negative effect on seedling morphological characters indicated by plumule and radicle length, number of adventitious roots as well as seedling biomass and water content. Water deficit could also suppress membrane integrity by stimulating lipid peroxidation with marked increase in membrane leakage and subsequent decrease in its stability index. For all the addressed germinat...

FT-IR analysis of Sapium ellipticum (Hochst) pax ethanol leaf extract and its inhibitory effects on pancreatic α-amylase and intestinal α-glucosidase activities in vitro
This study investigated the inhibitory effects of Sapium ellipticum (Hochst) Pax leaf extract on some carbohydrate metabolizing enzymes, pancreatic α-amylase and intestinal α-glucosidase activities in vitro. The inhibitory potential of SE extract was measured against Quercetin. SE extract in a dose dependent pattern significantly inhibited the activity of pancreatic α-amylase by 67.2% at 10 mg/mL. This effect was comparable to that of quercetin which offered 82.6% α-amylase inhibition. In terms of intestinal α-glucosidase activity, the inhibitory effect of the extract was significantly lower than that of quercetin a...

Numerical solution of quadratic Riccati differential equations
Publication date: Available online 6 September 2016 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Gemechis File, Tesfaye Aga The quadratic Riccati differential equations are part of non-linear differential equations which have many applications. This paper introduces the classical fourth order Runge Kutta method (RK4) for solving the numerical solution of the quadratic Riccati differential equations. To validate the applicability of the method on the proposed equation, some model examples have been solved for different values of mesh sizes. The numerical results in terms of point wise absolute errors...

Selective synthesis of acetone from isopropyl alcohol over active and stable CuO –NiO nanocomposites at relatively low-temperature
Publication date: Available online 5 September 2016 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Abd El-Aziz A. Said, Mohamed M.M. Abd El-Wahab, Mohamed N. Goda CuO–NiO nanocomposite catalysts were synthesized by an oxalate precipitation route. The basicity of the catalysts was measured using adsorption–desorption of acetic acid. The catalytic conversion of isopropanol to acetone was carried out in a conventional fixed bed flow type reactor at 200 °C using N2 as a carrier gas. The results indicated that, the addition of NiO to CuO greatly enhanced the electrical conductivity via the creation...
