Seeds of two rice varieties Basmati-370 and Basmati-385 were evaluated for invitro callus induction at Agricultural Biotechnology Institute in National Agricultural Research Center (NARC), Islamabad during 2001-02, using M.S and N6 media supplemented with 2, 4-D (2,4-Dichlorophenoxi acetic acid) and BAP (6-benzylaminopurine) at @ 2.0, 2.5 and 0.1, 0.5 mgl(More)
Nonlinear phenomena play a vital role in applied mathematics, physics, and engineering sciences. The Burger’s equation models efficiently certain problems of a fluid flow nature, in which either shocks or viscous dissipation is a significant factor. It can be used as a model for any nonlinear wave propagation problem subject to dissipation [1]. The first(More)
Irrigation of agricultural land with municipal wastewater has become a serious environmental issue due to soil contamination. The objective of the present study was to investigate the extent of contamination of vegetables grown on soil irrigated with untreated sewage water for the last four decades in suburban Peshawar. Samples of sewage water, soil, and(More)
THE THREE DIMENSIONAL FLOW PAST A STRETCHING SHEET BY EXTENDED OPTIMAL HOMOTOPY ASYMPTOTIC METHOD H. Ullah, S. Islam, M. Idrees, M. Fiza, A. Zaman Abdul Wali Khan University Mardan, 23200, Khyber Pakhtunkhwa, Pakistan ABSTRACT: In this paper Extended Optimal Homotopy Asymptotic Method (EOHAM), a new analytic approximate technique has been used to three(More)
The use of sewage-contaminated municipal water for irrigation of crops is an old practice in many big cities of Pakistan. Since the wastewater is rich in nutrients, it increases crops yield substantially but at the cost of food quality. The objective of this study was to investigate sewage water irrigation as a source of accumulation of heavy metals in soil(More)
In this paper Optimal Homotopy Asymptotic Method (OHAM) has been used to the flow past a rotating disk. This method is applied to the problem obtained from flow past a rotating disk shows its efficiency and effectiveness. This method control the convergence of approximate solution in a convenient way, when it is compared with other methods of solution found(More)
Surface physico-chemical and thermodynamic properties of non ionic surfactants (Tween 20 and Tween 80) with diblock copolymer poly (oxyethylene/oxybutylene) (E39B19) at 298 K have been investigated by surface tension and conductivity techniques. The surface tensiometery were used to study the critical micelle concentration (CMC), surface excess(More)
The cotton mealybug, Phenacoccus solenopsis Tinsley (Sternorrhyncha: Pseudococcidae) is a serious pest of various cultivated plants in Pakistan. Recent reports show that the parasitoid Aenasius bambawalei Hayat (Hymenoptera: Encyrtidae) is a good biocontrol agent of the pest. Compatibleness is important in any IPM programme, and the insecticide used must(More)
Rapid change in the environment due to global warming is not only linked with the scarcity of food but with the availability of green fodder also. Thirty mungbean genotypes were evaluated using randomized complete block design for fodder yield across years at two extreme environments of Pakistan; badly affecting by the flood. Broad-sense heritability and(More)
