This work is based on the derivation of four-step block hybrid methods for the solution of second order initial value problems (IVPs) in block mode. Power series was used as the basis function. Techniques of collocation ...

In this research, 4-step hybrid methods for solving second order initial value ordinary differential equations are developed with the use of Chebychev polynomial of first kind as the basis function. The approach is based ...

Herbicides are chemicals used to kill or control unwanted plants and weeds. They could accumulate in soils at toxic levels to contaminate groundwater when they are leached. The in vitro abilities of seventeen fungi isolated ...

There is extensive contamination of the aquatic environment when rivers and streams flow through areas of high human activities such as industrial cities and major towns. These contaminations may include enhanced ...

In order to adapt to the toxic compounds of plant origin which they constantly encounter during their feeding activities, insects have enzymes which facilitate detoxification. Such enzymes include glutathione-S-transferase ...

In this research, modification of raw Kaolin was carried out by three ways: thermal activation (TA); acid treatment (AA) and combined acid and thermal activation (ATA). The characterization of the modified kaolin clays ...

In this study, collagen from chicken, cow hide and goat skin were prepared using leather processing methods. The effects of pH, temperature, biomass dosage, contact time and initial metal concentration on aqueous Pb ...

Adsorption has been investigated as an effective technique for the treatment of waste water containing heavy metals, resulting from humans and industrial activities. The hazardous and adverse effects caused by heavy metals ...

The derivation of activated carbon from calcium hydroxide (Ca(OH)2)treated and untreated waterleaf(Talinumtriangulare) and amaranthus(Amanranthushybridus)was carried out. The potential of these adsorbents in the removal ...

Indiscriminate disposal of spent engine oil has been implicated as a major pollutant of soil and water. The effects of which are felt along the aquatic and terrestrial food chains, where the pollutants bioaccumulate in ...
