ABSTRACT Urban densification is as a result of increase in the level of urbanisation of a limited area which causes challenges in the housing affordability due to the increase in price of houses, high rental values, high demand and shortage in supply to meet the need of the urban residence. This study examines urban densification as an element of urban growth and how it can provide extra spatial information in ...

ABSTRACT In this work, performance of four mobile network operators (MNOs) was measured, analysed, and evaluated in Shiroro Power Station  and recommendation were made to improve the quality of their voice and data services. Drive test was performed using transmission environment monitoring softwares   (TEMs) and statistical analysis was done for performance evaluation. The results  shows that  the received signal strength level was between the ranges of -50 dBm to -110 ...

ABSTRACT Botanical extracts have shown appreciable achievement in controlling plant diseases. This became evident in this study when the potency of leaf extracts from Azadirachta indica, Carica papaya, Lawsonia inermis, Khaya senegalensis and Ziziphus spina- christi were tested on the mycelia growth of Colletotrichum falcatum, the pathogen of red rot disease of sugarcane. The infected sugarcane used for isolation and identification were collected from National Cereal Research Institute (NCRI) Badeggi. ...

ABSTRACT Water table fluctuation of selected hand dug wells, and hydraulic properties were determined. The methods of investigation included water level measurements, laboratory tests and analysis. The results indicated that the water level values for 16 wells under study ranged from 6.30 – 7.10 m (Minimum) and 25.40 – 26.30 m (Maximum) during rainy season, while the average during the dry season was 7.60 – 8.90 m (Minimum) and 27.10 ...

ABSTRACT The effect of loss in the availability of farm products has a lot of negative impact on the society. The decrease in crops production has created disparity between the food demand of world population and the global agricultural output. Crop production faces alot of challenges, some of which includes water scarcity, bad soils, unsuitable temperatures, pests, diseases and weeds which attacks the crops. Ground based or manual agricultural approach ...

ABSTRACT The study determined the effectiveness of Computer Aided  Instructional package (CAI) on achievement and retention of biology students in senior secondary schools in Minna metropolis. Four research questions were raised and four null hypotheses were tested. The study adopted the pre-test-posttest=control group design. A sample of one hundred and twenty (120) students from two intact classes from senior secondary two (SS II) of mixed gender were selected for this ...

ABSTRACT Housing is an integral element of a nation economy. Thus, focus on finance for housing projects has been more prominent due to huge financial resources that is required for provision of decent houses which is practically not at the disposal of low income earners in Nigeria. The aim of this study is to evaluate the effect of housing financing models on the delivery of housing project with a view ...

ABSTRACT A Tropical Black Clay (TBC), obtained by method of disturbed sampling, at a depth of between 0.5m to 1.5m, at Gwako village, Abuja, Nigeria, was treated with 0, 2, 4, 6, 8, and 10% each of Calcium Carbide Residue (CCR) and Coconut Shell Ash (CSA). Effect of the additives  was  investigated  with  respect  to  compaction  characteristics  (Maximum  Dry Density-MDD and Optimum Moisture Content-OMC) and Unconfined Compressive Strength (UCS) cured ...

ABSTRACT The growth of the telecommunication industry is fast paced with ground-breaking engineering achievements. Despite this, portable mobile handheld devices have very low computational, storage and energy carrying capacity occasioned by the needs to satisfy portability, very small form factor, ergonomics, style and trends. Proposals such as cloudlets, cyber foraging, mobile cloud computing (MCC), and more recently but most applicable, multi-access edge computing (MEC) have been proffered. New and emerging ...

ABSTRACT Distribution of Water has been a major source of concern all over the world. Despite the fact  that  water  is  a  scarce  commodity,  a  lot  of  human  activities  in  terms  of  poor management such as opening taps when not needed and careless attitudes towards broken pipes contribute to poor distribution. Furthermore, the supply of the commodity at constant pressure to areas when not needed contributes to little or no ...

ABSTRACT Cancer is the abnormal growth of cells in the body tissue which can spread out rapidly in any part of the body. Some common types include lung cancer, colorectum cancer, prostate cancer and breast cancer, among which breast cancer is the most predominant. Breast cancer forms and grow uncontrollably in the surrounding tissue of the breast. The disease has resulted in several deaths most due to lack of early ...

ABSTRACT Femtocells are overlayed on existing Macrocells to form Macro-Femto heterogeneous network (HetNet), to reduce cost of mounting expensive macrocell nodes, improve cellular network capacity and throughput performance. However, HetNet has a major problem of cross-tier and co-tier interference, which hinders its optimal performance, especially when the network capacity expands. With emergence of 5G technologies, interference would become more consequential. Therefore, curbing the effect of this interference is indispensable to ...

ABSTRACT A clayey soil collected at Barkindo along Lamurde-Adamawa road, Numan Local Government area of Adamawa State, Nigeria, was stabilized with 0, 2, 4 and 6% cement which was admixed with 0, 10, 20, 30 and 40% ceramic waste dust (CWD) each.  Index properties test and microstructural tests were conducted on the untreated clay soil while compaction tests and unconfined compressive strength tests were carried out on the untreated clay ...

ABSTRACT As interest in biomass utilization into combustion fuels grows, the torrefaction, becomes ever more important. Torrefaction is aimed to maximize energy by removing undesirable components (water, hemicellulose and volatile matter) which cause poor ignition characteristic, excessive smoking and low combustion efficiency when used for energy generation in boilers and  blast  furnaces.  In  this  research,  the  effect  of torrefaction  on  the  physiochemical  and combustion characteristic of tropical biomass (Mahogany Sawdust) ...

ABSTRACT Energy sustainability requires meeting our energy needs upon which economic development depends. The need to improve on the present power generating capacity of Nigeria, has brought about energy diversification by increasing the present energy sources to include renewable resources and this has led to the idea of this work. This work is aimed at determining the appropriate offshore wind farm location(s) in Nigeria to address the issue of wind ...

ABSTRACT Vernacular architecture is the expression of an individual person’s or society’s culture, history and locality or geographic area being reflected in their immediate environment and surrounding buildings. Buildings connect individuals to the culture, as the human desire to be culturally connected to ones surrounding is reflected in a harmonious architecture. The constant deterioration of the current Minna polo field, the bare nature of the field and the lack of ...

ABSTRACT The Hydraulics of flow in an open channel/waterway with flexible vegetation is studied. Vegetation along waterway has an ecological advantage; it enhances biodiversity, reduces erosion, and traps sediment. However, it has a hydraulic impact on flow. This study reviews hydrodynamics of vegetation along waterways (a concept to promote a sustainable green environment). It applies a modified one-dimensional (1-D) hydraulic model to replicate the vegetative velocity profile and Reynolds stresses ...

ABSTRACT The risk of occurrence of cancer in developed and developing nations has become a major concern in the scientific and medical circle. Cancer induction is therefore one of the risk to guard against during medical X-ray exposure. Constant assessment of radiological procedure are thereby crucial in ensuring radiation doses to patients are as low as reasonably achievable. The aim of this study is to determine the patient radiation dose ...
