Radiological and geochemical health and environmental impact assessments of cement production in Nigeria has been carried out in this study. Radioanalytical assays were carried out through gamma spectrometric detectors ...

Nonstandard propagation means the abnormal propagation caused by fluctuation in properties (such as density, refractive index) of the propagation medium due to the variation of atmospheric parameters within the troposphere ...

In recent years, higher frequencies are being adopted for radio communication and link systems design due to the congestion at the lower frequency bands. However, at these frequency bands, the atmospheric components, ...

The poor quality of drinking water and increase in water borne diseases have been of great concern which necessitates continued research for water purification. The use of organic materials for purifying water has been ...

Multipath propagation is one of the factors that causes radio signal degradation. The irregularity of the atmosphere causes variation of Point Refractive Gradient (PRG) with height and time of the day as well as season. ...

Cellulose nanocrystals (CNC) have gained prominence in a number of applications, such as in building materials, cosmetics, food, and the drug industry. Moringa oleifera has been noted to possess medical values which ...

The development of new families of generalized distributions in recent decades have attracted the interest of both theoretical and applied statisticians due to their flexible and tractable statistical properties. In this ...

Multicollinearity problem is associated with inter dependence of explanatory variables in linear regression model. The use of the Ordinary least Squares Estimator (OLSE) for the parameter estimation of the model produces ...

This work present a class of Obreckhoff-type methods for solving second order Boundary Value Problems (BVPs) with Neuwman and Dirichlet boundary conditions.This is achieved through collocation and interpolation techniques ...

Kwakil beans (Phaseolus vulgaris L.) starch and its derivatives were studied as potential adsorbents for heavy metals from aqueous solutions. The extracted starch was chemically modified through cross-linking using ...
