ABSTRACT Rainstorm Disaster is one of the challenges aspect that involve the interaction between man and environment of a wider public concern in the problem of environmental pollution and control. The reduction of the risk of this rainstorm disaster is a major concern to the research work as this natural disaster cannot be stopped but their devastating Effect can be reduced to the barest minimum.The need to sample the opinion ...

ABSTRACT The soaring trend of environmental contamination by heavy metals is a global issue. The continual monitoring of soils around industrial areas becomes necessary. The present study focused on the physicochemical and heavy metal concentration in soil around the vicinity of selected industries in Kaduna metropolis. The mean pH, electrical conductivity, % organic matter, % sand, % clay and % silt obtained were 7.16±0.35, 362.60 ±10.7µS/cm, 2.92±0.50, 76.50±0.81, 17.79±5.51 and ...

ABSTRACT The purpose of this study was to   assess teachers’ creativity in teaching mathematics in secondary schools in Keffi LGA of Nasarawa State. One hundred   SS2 students and ten mathematics teachers were selected from five senior secondary schools in Keffi LGA through stratified random sampling technique. The descriptive survey design was used. Two instruments  developed  by  the  researcher  were  used  to  collect  the  data.  The  Pearson’s product moment correlation statistic ...

ABSTRACT The construction industry is the economic prime mover of nations and it influences and propels infrastructural provision and development. Labour Efficiency losses on construction works have denied the reaping of the full benefits of the industry; as it has led to cost and time overruns, poor quality, claims and disputes. The aim of this study is to assess the effect of efficiency losses on the performance of construction projects, ...

ABSTRACT The released of hazardous and toxic elements like heavy metals from industries into the hydrosphere like oceans, rivers, lakes are a major concern in environment. Natural agents have high adsorption capacities for divalent metal ions. Pandanus is a natural adsorbent and in comparison  with  others  and  its  availability  in  Nigeria  is  cost  effective.  In  this  study,  the adsorption of heavy metal ions (Pb2+  and Ni2+) from sewage wastewater which ...

Abstract Macroinvertebrates organisms form significant part of an aquatic ecosystem which are of ecological and economic importance because they maintain various levels of interaction within aquatic environment. Emikpata stream in Doko district, Niger State, Nigeria is used for a variety of purposes such as irrigation, cattle drinking and domestic purposes. The macroinvertebrate diversity and water quality patterns of the stream were evaluated for a period of eight months using the ...

ABSTRACT Production and Characterization of oil from kerogen obtained from Bida Basin. In this study, kerogen from Bida Basin was used as a source of hydrocarbon for the production of oil and gas. Different thermal characterization such as Thermogravimetric Analysis (TGA) and Rock Eval (R.E) pyrolysis were employed. TGA was studied for the purpose of determining the thermal decomposition of kerogen. The decomposition of kerogen occurs at temperature of 308.28-471.68 ...

ABSTRACT Today most of the school building which are supposed to promote and enhance teaching, learning and extra-curricular activities are obsolete and thereby causing serious challenges to the 21st century educational needs of the learners. Most public secondary school hostels buildings in Niger state were built during the colonial era, many of them are so old that they are dilapidated and unsafe for human occupation. Thus, the study aims to ...

ABSTRACT The Mineral and Geothermal Potentials of part of Kogi State was investigated through the interpretation of aeromagnetic and radiometric data of the study area. Vertical and horizontal derivatives, Analytical Signal, CET, Euler deconvolution and Spectral depth analysis were used for the interpretation of the aeromagnetic data while the Concentration, Ratio and Ternary images of the three radiogenic elements were used for the interpretation of the radiometric data. The analysis ...

ABSTRACT Security and safety are important factors to be considered in every design. This has in recent times become an issue of concern especially in Northern Nigeria. This research sought to assess the effectiveness of the security measures employed in hotel designs by identifying  available  passive  security  features  within  existing  hotel  layouts  and proposing a design that employs these measures in addition to others discovered in literature. The study adopts ...

ABSTRACT Social infrastructure plays a vital role in the creation and development of healthy communities. It is seen as the backbone for every society to thrive and become habitable.

ABSTRACT The analytical needs in geographic information systems (GIS) have led to the interpretation of formal methods of modeling the topological relationship of spatial objects using Egenhofer-matrices. As a result, we investigate the algebraic approach for the structural analysis of a spatial topology- Simplices, The Order of Simplices, Faces of Simplices, Simplicial Complex, Skeletons of  Simplicial Complex. Oriented Simplex, Connectedness of Spatial Objects. The matrix interpretation of the eight spatial ...

ABSTRACT The demand for petroleum as a source of energy and raw materials for chemical industries in recent years has resulted in a tremendous increase in world exploration.
