ABSTRACT In this study, proximate analysis and characterization techniques were carried out on maize tassel fibres in order to check its feasibility as a bio-sorbent for bio-sorption process before the immobilization with Polyvinyl Alcohol (PVA). The moisture content, ash content, apparent density, particle size and crude protein of maize tassel fibre were determined to show that the bio-material was exceptional for its use in column adsorption. The surface chemistry of ...

ABSTRACT Civic centre is a reference point of any city where it is located and has been designed to attract interest, hence symbolic expression is one of the paramount requirements in a civic centre design. Biomimicry is defined as imitation of life. It would go a long way in enhancing the architecture of civic centre design in Nigeria. The capabilities that are abounding in biomimicry architecture could be explored in ...

ABSTRACT This study intends to investigate the analysis of removal of Methylene Blue (MB) and Brilliant Green (BG) dyes from aqueous solutions by adsorption on modified activated carbon prepared by chemical activation of coconut shell, eucalyptus tree, corn cob and flamboyant pod. The maximum percentage methylene blue removal was obtained as 95.0% for coconut shell, 93.2% for eucalyptus tree, 99.9% for corn cob and 99.7% for flamboyant pod with all ...

ABSTRACT Previous studies revealed low level of adoption of Building Information Modelling (BIM) in the Nigerian construction industry causing increased wastages, rework, time overruns, cost overruns, and adversarial relationships between project stakeholders. BIM adoption in Nigeria is at its infancy because majority of the knowledge of BIM exists only theoretically as much efforts are not being directed towards its application. This study therefore assessed the level of readiness for the ...

ABSTRACT In this study,  groundwater recharge in Otukpo basin  has been estimated using a modified daily soil moisture balance based on a single soil water store for a climate classified as tropical with distinct dry and wet seasons in the Middle Belt part of Nigeria. Soil properties like field capacity, permanent wilting point, readily available water, actual and potential evapotranspiration, soil moisture deficit were all estimated and deployed in the ...

ABSTRACT The present health challenges in our community such as diabetes and high blood pressure could be prevented by regular exercise. Lack of regular exercise and unavailability of exercise equipments lead to ill health problem. There is a need to design exercise equipment that reduces fatigue in our body. The development of exercise equipment with lesser weight and low assembly cost and time will help in reducing the health challenges. ...

ABSTRACT A study which lasted 70 days was conducted to determine the performance of Japanese quails (Coturnix coturnix japonica) fed diets containing four different protein and four energy levels. Five  hundred  and  seventy  six  (576)  Japanese  quail  aged  two  weeks  were  used  for  this experiment. Battery cages with 48 different compartments were used. The Japanese quails were randomly distributed into 16 treatments and each treatment was replicated three (3) times ...

ABSTRACT Fish farming is a major viable solution to the problem of protein inadequacy in Nigeria but the high cost of feed remains a major obstacle. This study evaluated the comparative effect of commercial feed and formulated diets on the growth and biochemical parameters of Heterobranchus bidorsalis (catfish) fingerlings. Proximate composition of fish wastes (FW), guinea corn (GC), groundnut cake (GNC) and bone meal (BM) were determined and used to ...

ABSTRACT The  aim  of  the  research  was  to  carryout  adsorption  study  of  the  removal  of chromium(vi) and copper(ii) ions from well water using pectin-chitosan polyelectrolyte complex as adsorbent. The optimum pH and ratio of pectin/chitosan was determined and the chitosan/pectin complex was characterized by using FTIR, BET, XRD, and SEM. Finally, removal efficiency of the PEC for chromium and copper was studied under optimum conditions. I.e. 0.4 g adsorbent mass, ...

ABSTRACT Child deprivation and how it can be reduced is a trending issue both at the global and national level especially in this 21st century. Despite the numerous policy and strategies put in place by the different tiers of government in Nigeria since independent in other to reduce Child deprivation in the country, deprivation is still persisting and has become a complex phenomenon that covers many dimensions of human and ...

ABSTRACT The increasing energy demand can be meet globally with the use of non-renewable fossil fuels, however the use of these fossil fuels is associated with tremendous release of CO2, which largely contributed to greenhouse gases effect (GHG‘s). Climate change or globally warning is one of the result of GHG‘s effect, to prevent global warming or climate change, the excess amount of CO2 in the atmosphere must be reduced to ...

ABSTRACT Governments around the world have set very ambitious goals and are running programmes for the implementation of electronic service delivery in the public sector. Public sector project suffers a lot setback in procurements innovation and the implementation of e-procurement technology. This study, thus, examined the implementation of e-procurement in public building construction projects. The study adopted quantitative approach. A total of 145 questionnaires were administered using stratified sampling method. ...

ABSTRACT The quantitative and qualitative shortfall of housing in Nigeria occasioned by population explosion is a primary driver of rental buildings. However, the quality of the rental buildings and satisfaction of tenants has become a major source of concern for government at all levels. Therefore, this study examines the quality and social relationship impact among tenants  of tenement houses in Minna, Niger State with the view to suggesting ways of ...

ABSTRACT The effect of feeding bitter leaf and moringa leaf meals based diets under single phase feed regime on growth performance, nutrient digestibility, carcass characteristics and sensory evaluation of broiler chickens was investigated. One hundred and eighty Cobb 500 strains of day old chicks were sorted and randomly distributed to six dietary treatments. Each treatment was replicated thrice with ten birds per replicate in a completely randomized design experiment. The ...

ABSTRACT Anthropogenic activities contribute the most to heavy metals pollution of water bodies around the world. This study was conducted to determine the spatial and temporal variation of heavy metal concentrations in sediment, water and in selected fish muscle from Shiroro Lake Niger State, Nigeria. Sediments and water samples were collected from three different stations across the lake for a period of eight (8) months between February and September 2019. ...

ABSTRACT The intrinsic suitability of some lateritic soils as materials for construction of layers for flexible pavements is evaluated herein. The pavement layers assessed were the base course, sub-base and sub-grade. Laboratory results of samples from these layers show that the CBR values of the sub-grade materials met the requirement while about 40% and 70% of the locations for sub-base and base materials respectively, presented CBR values less than those ...

ABSTRACT The  production  of  bioethanol  from  selected  agro  waste  (banana  and  cassava)  peels  was examined     using     Saccharomyces     cerevisiae     strain     CBS     1171and     Lactobacillus delbrueckii strain MN945906. The results of the proximate analysis shows that carbohydrate content were 67.85±0.23%, nitrogen (0.21%), potassium (64.7%), and phophorus (31.3%). The waste was hydrolyzed with Aspergillus niger strain MN945947 and Zymomonas mobilis strain MN945907 into 20g, 30g, and 40g, of the substrate for 7 days. The ...

ABSTRACT Sustainability  is a broad and complex concept, which is one of the major issues  confronting construction in the 21st  century. Sustainable principles, when applied, lead to the creation of systems that balance social, economic and natural resource requirements of the present and future generation. One of the major hindrances to the development and implementation of sustainability strategies in the construction sector is poor awareness level. Therefore, institutions of  higher ...
