A study of some systems of nonlinear partial differential equations by using Adomian and modified decomposition methods

African Journal of Mathematics and Computer Science Research

Afr. J. Math. Comput. Sci. Res.

In this paper, we introduce the solution of systems of nonlinear partial differential equations subject to the general initial conditions by using Adomian decomposition method (ADM) and Modified decomposition method (MDM). 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...

Influence of plant age on the content and composition of essential oil of Cymbopogon citratus (DC.) Stapf.

Journal of Medicinal Plants Research

J. Med. Plants Res.

An experiment was carried out in Viçosa, Brazil to evaluate the influence of plant age (3, 6, 9 and 12 months) on the content and chemical composition of essential oils from lemon grass, using a completely randomized design with three replications. The plants were harvested between 7:00 and 8:30 a.m, and harvesting cut made at 20 cm height from the base of the leaf. The collected material was immediately taken to the laboratory where the...

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

Evaluation of bean qualities of indigenous Arabica coffee genotypes across different environments

Journal of Plant Breeding and Crop Science

J. Plant Breed. Crop Sci.

Evaluation of bean qualities of 30 Arabica coffee genotypes were carried out at four different locations (South-western Ethiopia). The genotypes had high overall yield potential, during a preliminary evaluation carried out at Gera. The differences among genotypes for cherry weight (CW), bean weight, parchment length (PL), bean length (BL), floater beans and outturn percent at each location were highly significant (p < 0.01). Two genotypes: 8143... Read more
