The last decade has witnessed rapid growth in the deployment of wireless Local Area Networks (WLANs) based on the IEEE 802.11 standard. The IEEE 802.11 Wireless LAN (WLAN) has become a dominant technology for the (indoor) broadband wireless networking. The popularity of IEEE 802.11 networks comes with its low cost, high data rate and seamless […]

The present research work deals with utilization of Hibiscus sabdariffa stem as an adsorbent for the removal of RhB dyes from the aqueous solutions. The effect of contact time, initial dye concentration, dose of sorbent, chloride ions and pH were considered. Adsorption isotherm data were tested with using Langmuir and Freundlich modes and the adsorption […]

The use of treated urban wastewater as a resource for irrigation water is a practice widely employed in arid and semi-arid regions of the world but also one that is expected to become more diffuse due to the reduction of water resources and the climax in the competition for water. Researchers’ interests are, thus, focused […]

Low carbon steel is cheap and easily available, having all material properties that are acceptable for many applications. Heat treatment carried out on low carbon steel is to improve the properties such as ductility, toughness, machinability, refine grain structure, strength, hardness, tensile strength and to relive internal stress developed in the materials during cold or […]

Anthropology describes the scientific study of the origin, the behaviour, and the physical, social, and cultural development of humans. Forensic anthropologists are trained physical anthropologists who apply their knowledge of biology, science, and culture to the legal process. They identify human remains, along with pathologists, homicide detectives and other specialists. Age determination of unknown human […]

This paper proposes some new criteria for seakeeping performance of naval submarine seaworthiness behavior. For ships, there are twelve criteria for seaway performance analysis. The scope of mission, systems and device’s restrictions, hull shape, hydrostatics and stability properties of ships and submarines are essentially different. In snorkel condition, only snorkel mast is above the water […]

This study was conducted to determine the effects of pesticide application on soil microbial spectrum using a herbicide (Glyphosate; the active ingredient in Roundup) and an insecticide (Chlorpyrifos). The control soil samples had no pesticide application. Soil samples taken at the depth of 0-20cm from the Biological Garden was taken to the laboratory. The soil […]

This article unveiled the causes of engineering plant failure. Re examined preventive, corrective/shutdown and predictive maintenance strategies in light of the prevalent maintenance approaches in a contemporary engineering and developing nation, in a bid to proffer effective maintenance strategies that will provide an acceptable level of plant operation. It found maintenance to be a practice […]

The effects of corrosion and the inhibitive effects of plants extract were investigated on samples of mild steel immersed in Hydrochloric acid. Findings have shown that inorganic chemicals used to inhibit corrosion of some organic material, are also suitable for corrosion inhibition of metals and their alloys. Extracts of mango and sweet orange were investigated […]

Geography is a diverse science or social science discipline that involves the investigation of man and its physical surroundings. Numerous reasons have been identified to have caused the poor performance of secondary school students in geography among which the use of appropriate instructional strategies or teaching methods is paramount. The study investigated the effectiveness of […]
