ABSTRACT Wireless sensor networks (WSN) consist of micro-sensors capable of monitoring physical and environmental factors. These are often mainly made up of resource constrained sensor nodes and gateways. Networking these nodes presents several challenges because the devices have limited computational capability, data storage, energy and communication bandwidth. Therefore, various lightweight communication protocols are emerging for Machine to Machine (M2M) communications.  Among the  various  application  layer  protocols  for  data  communication  in ...

ABSTRACT Biosurfactant-mediated degradation of contaminants is practical and safe environmental remediation agent. In addition, iron oxide nanoparticles and biochar are bioremediation agents with great potentials due to their strong adsorption capacity, microbial growth enhancement and chemical inertness. Therefore, a combination of biosufactant, iron oxide nanoparticles and biochar could produce a very desirable and efficient alternative to conventional environmental treatment of contaminants. This study focused on the development of biosurfactants-ironoxide nanoparticles-biochar ...

ABSTRACT Economic recession occurs when “economic activity declines, in other words, growth become negative “and it is associated with low- level consumer spending. A recession also known as go-slow in terms of Gross Domestic Product (GDP) or national outputs has led to increase in unemployment, a decrease in wages, a high level of inequality, and an increase in government borrowing. Fall of Nigerian currency, so much reliance on oil, and ...

ABSTRACT Geothermal Heat Flow Analysis over the Upper Sokoto Basin Nigeria, using Aeromagnetic Data was carried out to determine the geothermal heat flow in the area. The study area extends from latitude 12.50°N to 13.50°N and Longitude 4.00°E to 6.00°E. Polynomial fitting method was applied in the regional – residual separation from the digitised data. The observed magnetic residual anomalies map was Fourier transformed after dividing the area into 24 ...

ABSTRACT The issue of professional valuation standards and the quality of valuation reports has been the focus of considerable attention not only in Nigeria but also internationally in recent years. The aim of this study is to investigate the level of adherence to valuation standards and property value certification by Estate Surveying and Valuation firms in Lagos, Nigeria with a view to establishing a mechanism for improving compliance level to ...

ABSTRACT Over the years, the use of plant-based molluscicides has received substantial consideration in the satisfaction for cost-effective alternatives to chemotherapy and synthetic molluscicides in schistosomiasis control. This study was aimed at evaluating the molluscicidal potentials of crude and Alkaloidal fractions of Anogeissus leiocarpus and Pseudocedrela kostchyi against vector of schistosomiasis. Both aqueous and methanol crude extracts of the plants were tested for the presence of bioactive metabolites. Ten snails ...

ABSTRACT This research presents the development of a piston material from aluminium alloy using coconut shell ash as an additive. Most damage pistons reported in literature are as a result mechanical fatigue due to wear and thermal fatigue. Investigations revealed that aluminium alloys have relatively poor wear resistance, and researchers are concerned with  reinforcing  aluminium  alloy  for  improved  properties.  The  present  work  used coconut shell ash for the reinforcement. The ...

ABSTRACT The Nigerian Construction Industry (NCI) faces numerous cost-related challenges that have in some cases increased costs of construction projects by up to 61.84%. Such challenges include the increasing complexity of construction projects which necessitate specialist skills required for their design, construction, operation and maintenance. The control of the cost of construction projects, Project Cost Control (PCC), is thus confronted by new problems, as well as the use of old ...

ABSTRACT The non-implementation of risk management techniques constitutes a lot to most of the project failures encountered nowadays. This leads to variations, incessant claims due to time loss by the contractor and loss of significant stakeholder’s value. This study assessed risk response techniques for construction projects under Design Bid Build and Design & Build (DBB and DB) procurement methods in Abuja, with a view to enhancing the level of understanding ...

ABSTRACT The aim of this study was to determine the effect of sprouting on the amylases activity and functional properties of ten FARO rice varieties. The FARO rice samples selected randomly were used for this study, and these include FARO 15, 16, 20, 22, 30, 45, 47, 55, 61 and 62. They were sprouted for twelve (12) days according to standard procedures, in order to determine the amylase activities and ...

ABSTRACT Water is explicitly linked with economic progress and developmental trajectories of most countries and regions of the world. However, inspite of its significant contribution to quality of life, public health and socio-economic development, water scarcity has continuously remained one of the most excruciating problems around the globe. In view of the disproportionate nature of water scarcity, both  in space and time, coupled with urban population growth dynamics this thesis ...

ABSTRACT Fire disaster is one of the most drastic disasters known to man. It’s wide and fast spread especially in populated areas and ability to consume everything reaffirms the severity of the aftermath of fire incidences. The study is majorly concentrated on the appraisal of existing institutional capacity in Niger state with a view to making recommendation for effective management of fire disasters in the state, in other to achieve ...

ABSTRACT Ensete gilletii commonly called wild banana, is ethno-medicinally used for the treatment of diarrhea, dysentery, typhoid, stomach pain, kidney stone and liver disorders by herbal practitioners. The dried pulverized roots of the plant were subjected to exhaustive, successive soxhlet extraction using petroleum ether, chloroform and methanol. The result revealed that a higher percentage yield was obtained from the methanol extract (MEG). The GC-MS analysis of the petroleum ether crude ...

ABSTRACT A two phase research work was conducted in a period of 12 weeks to determine the effect of feeding varying levels of fermented cassava (Manihot esculenta) peel meal on the growth performance and egg production of Japanese quails using 300 two week old growing quails with an initial mean body weight of 27.67 g of both sexes. The birds were randomly allotted to 4 dietary treatments with 75 birds ...

ABSTRACT Housing is a basic need of every human being just as food and clothing. Density simply refers to how much of a particular object or thing there is in a particular unit of space. The aim of this research work is to analyze urban land use planning, with the view to knowing the major density type and the area exhibiting the highest residential land use in Minna metropolis.  This ...

ABSTRACT The occurrence of flood events has brought a lot of miseries to man and his environment. Farmers have continued to experience yearly loss of lives, properties and farm land to flood events that are caused by heavy rainfall and discharge of water from River Niger Nigeria.
