Year of Publication
Publication Type
Abstract
Termite mounds are good examples of a well regulated ecosystem structure. These social insects are ecosystem engineers that are capable of building mounds of various sizes. Macrotermes mounds are equipped with several openings at various positions to mitigate thermoregulation and ventilation. One possible means of understanding the thermoregulatory pattern and ventilation strategies within a Macrotermes mound is to assess the relationships between its respiratory structures and geometry. Here, correlation test were done to test the level of significant relationships between the mound geometry and ventilatory structures. Results showed that the ventilatory structures above the base of Macrotermes mound is significantly (p<0.05) related to Its overall size (height, column, width) with correlation coefficient of 0.7323142, 0.668158 and 0.6531674 but had no relationship with the depth and perimeter of a Macrotermes mound. However, the ventilatory structure at the basal portion was significantly related to the depth with correlation coefficient of 0.7428268 and not necessarily the size of a mound. The temperature of a mound surrounding is also related to the internal temperature R=0.7074602, p=0.0004, R2=0.5005), and also deterministic factor in assessing the temperature flow within a Macrotermes mound. This ventilatory structures coupled with temperature are typical strategies used by termites to create a well thermoregulated and ventilated structures. The implications of these findings are that Macrotermes bellicossus mounds can be employed by humans in the construction of buildings, such that a time we come where there will be little or no need for
artificial ventilators like Air conditioners.

Abstract
This study empirically investigated the value relevance of non- financial information in the annual reports of commercial banks in Nigeria. The study is important as it portrays the extent to which non-financial disclosures influences share prices. Using the Ohlson (1995) model which was modified, the study used share price as a measure of the value of the commercial banks while, Corporate Environmental Disclosure(CED), Corporate Governance Disclosure (CGD) and Corporate Social esponsibility Disclosure (CSRD) were used as the proxy variables for Non-Financial Disclosure ( NFD). Ex post facto design was adopted and data for the study were obtained from the published annual reports of the thirteen commercial banks listed on the Nigeria Exchange Group
(NGX)from 2016–2020. The findings generally indicate that environmental and corporate social responsibility assert a positive and significant effects on firm value of commercial banks while, corporate governance disclosure asserts a negative and significant influence on the value of the banks. However, this study suggests that firms should disclose more
of these information in their annual report as these information disclosures have exerted significant influence on firm’s performance over the years.

Publication Type
Abstract
The increasing demand for sustainable energy sources has driven the exploration of biodiesel as a viable alternative to fossil fuels. This study focuses on the development of biomass-derived catalysts for the production of biodiesel using a blend of non-edible oils: neem, shea, and jatropha. The research aims to address the challenges associated with conventional catalytic processes, such as high costs, environmental impact, and inefficiencies, by utilizing agricultural waste products to create sustainable and cost-effective catalysts.
The project involved the synthesis of biomass-derived catalysts from plantain peels and coconut husks, which were characterized for their physical and chemical properties. The transesterification process was optimized using the Box-Behnken Design (BBD) to determine the effects of reaction temperature, reaction time, catalyst load, and methanol-to-oil mole ratio on biodiesel yield. The results indicated that the optimal conditions for biodiesel production were a reaction temperature of 60°C, a reaction time of 90 minutes, a catalyst load of 5.5 wt%, and a methanol-to-oil mole ratio of 6.5:1, yielding a maximum biodiesel yield of 92.37%.
The biodiesel produced from the oil blend was characterized according to ASTM standards, and the results showed that the physical and chemical properties, including density, viscosity, flash point, and acid value, were within acceptable limits for biodiesel. The study demonstrated that biomass-derived catalysts are effective in producing high-quality biodiesel from non-edible oil blends, offering a sustainable and economically viable alternative to conventional catalysts. This research contributes to the advancement of renewable energy technologies by providing a framework for the utilization of locally sourced agricultural waste in biodiesel production. The findings highlight the potential of biomass-derived catalysts to enhance biodiesel yield and qualitywhile reducing environmental impact, thereby supporting the transition to sustainable energy
solution.

Year of Publication
Publication Type
Abstract
The main purpose of the project was to design a 3.5KVA inverter which makes use of both solar and mains or grid supply for charging the batteries. This is to reduce the frequency of power outages experienced in our homes and businesses. The project was carried out with the use of two 12V batteries connected in series to give a total of 24V DC which would serve as input for the inverter when on inverting mode and give an output of 220V AC for household appliances. Incorporated within the inverter was load control features, such that when the inverter stops charging and starts inverting, at a particular battery level set by the user, the heavy loads would be cut off while supply of power to the light loads continues. But when critical battery level is reached the light loads are also cut off and the inverter shuts down. This was done using Microcontroller in controlling relays which either powers on the load or cuts off the load when the battery is low. The proposed inverter design has two outputs through which load management was achieved. One of the outputs is designated to light loads and the other to heavy loads. The Microcontroller DSPIC30F4012 controls the load stage which can be programmed through the keypad to monitor the output power to the loads in output one and two, to ensure they do not draw power beyond the limits programmed by the user. To achieve this, the Microcontroller cuts off either of the outputs which exceed the set limit. The project was successful and the test results obtained was satisfactory. The inverter's operation was consistent with the design and the desired control of power consumption and power management was achieved.

Abstract
The issue of national security is contentious and indeed, a subject of immense concern to every Nigeria and Government which has ruled from independence to the present day. It is a subject that concerns the survival of a nation in the international system. However, there is a correlation between national security and pursuit of a foreign policy. In the past, there was demarcation between foreign policy and national defence policy. The truth remains that no nation can play meaningful role in the international system, if the state does not have dynamic foreign policy linked up with her defence policy.

ESIGN AND FABRICATION OF A SOLAR POWERED GRINDING MACHINE

Year of Publication
Publication Type
Abstract
As global engineering practice increasingly prioritizes the elimination of greenhouse gas emissions and environmental pollution, the development of renewable energy-powered equipment represents a critical pathway toward sustainable industrial operations. This project focuses on the design and fabrication of a solar-powered grain grinding machine that harnesses photovoltaic technology to provide an off-grid, zero-emission solution for agricultural processing in rural areas where conventional electricity supply is unreliable and diesel-powered alternatives contribute significantly to carbon emissions and operational costs. The system employs a 350W brushless DC (BLDC) motor operating at 24V and 1500 RPM, powered by a 200W monocrystalline solar panel with battery backup comprising two 12V lead- acid batteries connected in series. A pulse width modulation charge controller regulates the charging process while providing comprehensive battery protection. The mechanical subsystem features a food-grade stainless steel hopper feeding into a burr-type grinding mechanism with 80mm diameter hardened steel grinding plates, enabling adjustable fineness control for various grain types. Power transmission from the motor to the grinding shaft is achieved through a universal joint coupling, with the complete assembly mounted on a fabricated mild steel frame. System performance analysis reveals a comprehensive energy conversion pathway from solar input to mechanical grinding output. The electrical subsystem demonstrates strong efficiency with the PWM charge controller achieving approximately 78% efficiency and the BLDC motor operating at 85-90% electrical-to-mechanical conversion efficiency. The mechanical drivetrain, comprising the universal joint, bearings, and shaft assembly, maintains approximately 85% transmission efficiency. These results in a net system operational efficiency of approximately 58% from battery DC output to mechanical grinding power. Under typical operating conditions, the system delivers approximately 315-320W of net mechanical grinding power from the 350W motor rating, accounting for motor efficiency and mechanical losses. Performance testing validated a grinding throughput of 5.0-10.0kg/hr for various grain types including tomatoes, pepper, millet etc with an estimated Specific Energy Consumption (SEC) of approximately 42Wh/kg. Environmental benefits include zero operational carbon emissions, elimination of air and reduced noise pollution, and contribution to sustainable rural development. The system eliminates recurring fuel costs associated with diesel generators, reduces monthly operating expenses for minimal maintenance, and provides payback periods of 1-3 months for small-scale commercial users.
