ABSTRACT The El Nino Southern Oscillation (ENSO) has some level of control over the weather of Nigeria and Africa seasonally but there has been enough debate as to the extent of the control. ENSO magnitudes do not necessarily translate into impacts in the same direction hence, attempt to investigate possible teleconnections with the Indian Ocean Dipole Mode Index (IODMI) phases over equatorial Indian Ocean that could explain the subsisting gaps ...

ABSTRACT The chemical and mechanical properties of  recycled mild steel from scraps in Nigeria was investigated using the mechanical (strength of materials) testing approach, chemical (elemental composition) testing approach and metallurgical (microstructural analysis) testing approach methods. The aim of this study is to investigate the quality of recycled mild steel reinforcement used for engineering applications in Nigeria by obtaining as- produced mild steel samples of 12mm diameter rod used for ...

ABSTRACT Social infrastructure includes public primary schools (PPSs) and primary health care facilities (PHCs) which are essential in fostering community wellbeing, cohesion and development. For efficiency in the distribution of social infrastructure, population or travel distance can be used as a criterion for allocating social infrastructures. This study assessed the inadequacy and spatial inequality in the distribution of social infrastructure in Zuru local government of Kebbi State using both primary ...

ABSTRACT Effect of vertical rectangular openings on the flexural strength of reinforced concrete beam is presented. Twelve reinforced concrete beams of dimension 200m x 230mm x 700mm with different sizes of rectangular openings, 25mm x 35mm, 50mm x 60mm and 75mm x 85mm which are placed at 150 mm from the supports, were cast. After curing, these beams were tested under centre-point loading system using universal testing machine and the ...

ABSTRACT This study investigates the removal of chromium from simulated aqueous solution of potassium chromate using intercalated Nigeria Ahoko kaolin.  One of the most important problems of contamination at present is the existence of heavy metals owed to their toxicity and cumulative properties. Adsorption process was used for the removal of chromium in this study. The adsorbent was initially refined to remove the quartz content. The adsorbent was intercalated with ...

ABSTRACT Deciding what to provide in-house and what to outsource is not always easy, because of the pros and cons of each approach. This study assessed the suitability of outsourcing and in-house routes for procurement of facilities management (FM) services in public buildings so as to develop a framework to assist FM practitioners in making decisions on procurement of FM services in Abuja. Mixed method research methodology was adopted involving ...

In today’s society, adopting culture in design of hospitality buildings will have  a  significant  impact  on  how  customers  describe  their  service  experience  for cultural features translate different meaning in ...

ABSTRACT The 21st  Century has been characterised with an unprecedented rate of urbanisation. Presently, about 50% of global population are resident in cities, and this is projected to rise to 70% in year 2050. This rapid rate of urbanisation is associated with unemployment and urban food security challenges. To address the food security challenges in cities, urban residents have embraced the practice of urban agriculture – a practice which involves ...

ABSTRACT The purpose of the study is to develop a lot sizing model for growing chickens if the supplier of the products offers incremental quantity discounts. A mathematical model was derived to determine the Optimal Inventory Policy which minimizes the total inventory cost in both the owned and rented facilities. A solution procedure for solving the model is developed and illustrated through a numerical example. Sensitivity Analysis was performed to ...

ABSTRACT Automated  system  of  fish  farming  has  become  inevitable  due  to  the  immense importance of fisheries aquaculture. The efficiency of any fish rearing system depends on monitoring and control of pond water quality parameters as well as adequate feeding and a reliable power source. This work presents a fish pond monitoring and control system that improves on the efficiency of fish rearing. A sensor network consisting of temperature, pH, turbidity ...

ABSTRACT Antimicrobial agents of plant origin have enormous therapeutic potentials. Honey, which is a product of plant, is a sugary substance produced by bee from the nectar of flower. It has been an age long antimicrobial therapy for wounds and burns.
