The proposed Adomian and Modified decomposition methods was applied to reformulated first and second order initial value problems, which leads the solution in terms of transformed variables, and the series solution will be...

Phytochemical screening and study of antioxidant and analgesic potentials of ethanolic extract of Stephania japonica Linn.

Journal of Medicinal Plants Research

J. Med. Plants Res.

The present study was conducted to evaluate the possible phytochemicals present, antioxidant activity and analgesic potential of ethanolic extract of leaves of Stephania japonica (Linn.). For investigating the antioxidant activity, four complementary test systems, namely 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, reducing power assay, Fe++ ion chelating ability and total phenolic content were used. Analgesic activity of the... Read more

Transhumant migration of Baruwal sheep (Ovis aries): A case study from the Kanchenjunga conservation Area of Nepal

African Journal of Agricultural Research

Afr. J. Agric. Res.

The transhumant sheep production is traditional farming system adopted by the herders of the Kanchenjunga Conservation Area (KCA) of Nepal. A rapid field survey by was organized in the KCA of Nepal in order to know the basic of transhumant sheep production in the focus group discussion (FGD), it was learned that the current number of herders and sheep population were sharply declined since the last two decades in KCA. Among the problems identified,... Read more

Combining ability and heterosis for different agronomic traits in maize (Zea mays L.) under drought stress in the Sudan Savanna of Borno State, Nigeria

Journal of Plant Breeding and Crop Science

J. Plant Breed. Crop Sci.

Combining ability variances were estimated for grain yield and its related traits in maize (Zea mays L.). Nine maize varieties consisted of five IITA open pollinated varieties (OPVs) and four local varieties were crossed in line x tester mating design. During the 2007 cropping season to determine the general combining ability (GCA), specific combining ability (SCA) effects and heterosis. Parents and hybrids were evaluated in Damboa during the...
