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 ...

In this research, the annual effective dose rate (AEDR) due to ionizing radiation in 20 Local Government Areas (LGA) and 37 Local Council Development Areas (LCDA) in Lagos State, Nigeria have been determined. Data ...

To achieve good design of line-of-sight (LOS) at the VHF/UHF band/communication networks, knowledge of the radio refractive index of the atmosphere is required. The measurements of meteorological parameters of atmospheric ...

The research work is aimed at establishing an environmental standard for powering Base Transceiver Stations (BTS) using different hybrids of renewable energy resources (RES) with optimal performance in cost consideration, ...

Power supply failure does not promote development to public and the private sector. Processes such as surgery operation in hospitals, research activities and even communication at airports are so important that their ...
