Mathematical algorithms offer a useful method for quantitative analysis of compounds in multi-component mixtures to overcome the overlapping problems occurred in UV spectrophotometry. The aim of this study is to develop a method to determine the bioactive compounds in herbal dosage forms produced from fenugreek extract. A UV- spectrophotometric method based on mathematical algorithm was used to...

here, a new method called aboodh transform homotopy perturbation method(athpm) is used to solve nonlinear partial dierential equations, we presenta reliable combination of homotopy perturbation method and aboodh transformto investigate some nonlinear partial dierential equations. the nonlinearterms can be handled by the use of homotopy perturbation method. the resultsshow the eciency of this...

in this paper, a new and ecient approach based on operational matrices with respect to the gener-alized laguerre polynomials for numerical approximation of the linear ordinary dierential equations(odes) with variable coecients is introduced. explicit formulae which express the generalized la-guerre expansion coecients for the moments of the derivatives of any dierentiable function in terms...

in this study we produced a new method for solving regular dierential equations with step size h and taylor series. this method analyzes a regular dierential equation with initial values and step size h. this types of equations include quadratic and cubic homogenous equations with constant coecients and cubic and second- level equations.

Laser induced fluorescence (LIF) excitation scans and dispersed fluorescence (DFL) spectra have been recorded for two four-carbon α,ω-diphenyl systems, diphenyldiacetylene (DPDA, φ-C≡C-C≡C-φ) and trans-diphenylvinylacetylene (DPVA, φ-CH≡CH-C≡C-φ) as isolated molecules cooled in a supersonic expansion. While these molecules have similar conjugation length, they exhibit strikingly different vibro...

Th eir storage capacity is comput ed as well as the attrac tion basin of each memorized pattern. We show how such systems can be used when the patterns to be memorized have a subset of relevant features; "s...

Reaction of (NBu3H)3[W(CN)8]·H2O and linear trinuclear complexes [Cu(II)2L2Ln(III)(NO3)3] (L = 2,6-di(acetoacetyl)pyridine, Ln = Eu (1), Gd (2), Tb (3) and Dy (4)) leads to the formation of four one-dimensional (1D) complexes. Single crystal X-ray analysis reveals that [W(CN)8](3-) bridges between the [Cu(II)2L2Ln(III)] sub-building units to construct the alternative chains. Magnetic investigat...

This study provides an analysis of the aid-private capital flows-growth nexus for Ghana. It is premised on the argument that Ghana’s new status as a middle income country plus the start of oil production is bound to result in a reduction in ODA inflows in the long term. However in the short to medium term ODA will remain an important component in the country’s fiscals as well as an important to...

In this paper we focus on the relationship between remittance inflows and financial inclusion in developing countries. We present single equation estimates on remittances and financial inclusion, and system estimates in which economic growth is explained by e.g., financial inclusion, and financial inclusion by, e.g., remittances inflows. These regressions clearly confirm our main hypothesis tha...

This working paper examines the validity of the claim that ‘scaling up’ ODA in developing countries will cause ‘Dutch Disease’ effects that slow growth and human development. The most common concerns are increased inflation and exchange-rate appreciation. Consistent with a recent IMF re-appraisal, the paper maintains that such problems can be mitigated if ODA is properly ‘spent’ and ‘absorbed’....
