This research focuses on derivation of Chebyshev-fitted hybrid methods for solving initial value problems of fourth order ordinary differential equations. In the derivation, Chebyshev polynomial of first kind was used ...

Missing values occur in almost all research. They are either removed or replaced with estimated value(s) before the data set is further analyzed. In this study, another method of replacing missing values is proposed for ...

Solar quiet daily variations (Sq) in three geomagnetic elements namely the horizontal intensity (H), declination (D) and vertical intensity (Z) are investigated for the influence of their smaller waves (local effects) ...

Soil and indoor radon concentrations were measured in 94 workplaces and 118 homes in selected cities/towns in Ondo state, south-western Nigeria with the aim of estimating the radiological effects on dwellers. The measurements ...

The knowledge of the variation of surface radio refractivity is required for planning of broadcasting services including terrestrial radio links over a region. The reduced–to–sea–level refractivity, No, values will remove ...

An intruder alarm system monitors and detects unauthorised entry to properties – homes and businesses alike - and alert the property owner or authorised third parties to an intrusion Security is a prime concern in our ...

The antibacterial efficacy of leaf extracts from guava Psidium guajava (Linn) were assessed on bacterial indicators isolated from two groundwater sources that are prone to faecal contamination in Akure, Nigeria. The load ...

This research aimed at screening bacterial isolates associated with the rumen of cow and goat for cellulase, xylanase and mannanase production, partially purifying and characterizing them. Ruminal samples from cows and ...

Probiotic foods are functional foods which provide healthy benefit beyond nutrition. In this study, non-dairy probiotic drinks were produced from tigernut extracts and soymilk. In the production of this probiotic drinks, ...

Urease producing bacteria are significant for their increasing roles in human pathogenicity, biocementation and as soil fertilizer. This study was therefore, aimed at isolation of urease producers from urea-rich soil samples ...
