(G´/G, 1/G)-expansion method for traveling wave solutions of (2+1) dimensional generalized KdV, Sin Gordon and Landau-Ginzburg-Higgs Equations

The-expansion method is one of the most direct and effective method for obtaining exact solutions of nonlinear partial differential equations (PDEs). In the present article, we construct the exact travelling wave solutions of nonlinear evolution equations in mathematical physics via (2+1) dimensional generalized KdV, Sin Gordon Equation and Landau-Ginzburg-Higgs Equation by -expansion method,...

Positioning fruit trees into climate change/variability scenarios: Opportunities and constraints in the placement of fruit tree species in payment for environmental services

Extreme environmental conditions due to climate change or variability are a threat to crop production, productivity and livelihoods. Thus, providing alternative livelihoods to communities, especially the rural masses remain an important catalyst in reducing poverty, food insecurity and deforestation in the development of climate change/variability scenarios. This is critical in southern Africa where poverty,...

Interaction of the extracts of three medicinal plants with antibiotics against some antibiotic resistant bacteria

The outcome of in vitro interaction of standard antibiotics with ethanolic leaf extracts of three medicinal plants (Picralima nitida, Chromolaena odorata andAspilia africana) against antibiotic resistant bacteria was investigated by agar disc diffusion methods and macrobroth dilution techniques. At least three isolates each of Escherichia coli, Staphylococcus aureus and Pseudomonas...

Technological quality attributes of pork from a small-holder abattoir as affected by breed, age and season of slaughter

The objective of the current study was to determine the effect of breed, age group and season of slaughter on technological quality attributes of pork from a smallholder abattoir. Meat from the Large White pig meat had higher (P < 0.05) pHuand lower a* than values of meat from the Landrace. No breed differences were observed in lightness (L*), yellowness (b*), shear force values, thawing loss, cooking loss and...
