Itebukunmi is a riverine community in Ondo State Nigeria, known for its high traffic in fishing activities. The economic importance of fishing activities in Itebukunmi to the Nigerian economy necessitate the need to study the harvesting strategy of fishing in Itebukunmi waters and where necessary determine scientifically regulatory policy that will ensure sustained growth in population.
The Mathematical model of three species of fishes in Itebukunmi couple with human activites was derived using systems of ordinary differential equations. The qualitative analysis of the model such as the local, global, stability and bioeconomic analysis were done using linearization approach and bifurcation analysis. The result of the quantitative analysis showed that : as the control of the harvesting rate of cat fish increases, the population of cat fish and African knife fish, in Itebukunmi river increases, while the Ophiocephalus fish population decreases. Also, as the control of the harvesting rate of Ophiocephalus fish increases, the population of Ophiocephalus fish and African knife fish, in Itebukunmi river increases, while the cat fish population decreases. Furthermore, as the control of the harvesting rate of African knife fish increases, the population of African knife fish , in
Itebukunmi river increases, while the cat fish and Ophiocephalus fish population decreases

This project presents the design and implementation of a Class Academic Resource
Distribution System developed for the Department of Computer Science, University of Benin. The system was created to solve the problem of disorganized and unverified learning materials shared through informal channels such as WhatsApp and Google Drive. It provides a centralized web-based platform where lecturers and class representatives can upload course-specific, lecturer-approved materials, while students can easily access them in one place. The project adopted the Rapid Application Development (RAD) methodology and was implemented using HTML, CSS, Python (Django), and MySQL. System testing confirmed efficient performance, secure access control, and reliable file management. The platform successfully improves accuracy, accessibility, and communication among students, lecturers, and class representatives, laying a strong foundation for future departmental and university- wide deployment.

Production of African Black soap using cocoa pod husk ash (alkali base) and palm kernel oil is essentially crude soap obtained from the process of Saponification. The cocoa pud husk were carbonized (burnt to ashes ) and the Alkali was extracted from it by dissolving in water and later filtered. The suitability of the Cocoa Pod husk ash as an alkali source for soap production was evaluated, the Alkali extracted was made to react with hot palm kernel oil and the resultant mixture is the African Black soap. The soap formed was analysed. The values of the pH test, foamability test and Lather volume analysed were 9.0, 300ml and 6.33 minutes. The analysis however has revealed that the African black soap can compete favourably with other toilet soaps in the market and can also be improved on. So therefore, using cocoa pod husk for the production of the African black soap, can be modelled to preserve this age-old craft and guarantee that future generations continue to use the traditional methods of creating soap which serve as job opportunities for local and modern communities and women's cooperatives.

Five (5) marble samples from Igue and Environs in Southern Nigeria were obtained with the aim of qualifying the marble using XRF as well as XRD techniques and determining its economic importance. The major element composition of the marble deposit shows it has a mean chemical composition of CaO (91.14 wt. %), MgO (0.64 wt. %), SiO2 (4.17 wt. %), K2O (0.16 wt. %), Al2O3 (2.57 wt. %) and Fe2O3 (0.40 wt. %), respectively. The modal composition of the marble is, Calcite (65.1 %), Quartz (14.74 %), Orthoclase (7.66 %), Lime (6.5 %) and Illite (5.96 %). The results of the analysis revealed that the Igue marble is highly calcitic in composition. The ternary plot tends towards CaO and CaCO3 which confirms the former. Subject to beneficiation, Igue marble can be used for cement production. Igue marble is also used for sculpture, tiles, chips and decorative purposes. It is suggested that detailed trace element analysis should be carried out on the marble.

The Digitally Programmable Temperature/Time-Based Control System puts forth a system which enables users to choose the preferred temperature for the water to be heated while the device is in the temperature mode. The design is built with the objective of implementing a digital temperature monitoring circuit that will collect the temperature of water and send the value, digitally to a microcontroller and to create an alerting mechanism that will be in the form of an audio alarm and a visual display to alert the operator that an operation is done. By also providing precise temperature regulation and accurate timing the water heater will turn on when the user sets the desired temperature via the input switches, and the screen will begin counting down from the chosen time to zero. A signal from the microcontroller will be sent to the transistor's base through the resistor when the water reaches the specified temperature, cutting off the power to the heater. In order to activate the relay, the transistor must become saturated. Given that the heater is linked to the relay's typically open contact, the water heater will be turned off. The flow chart were established, which helped with the proper circuit diagram design and simulations utilizing electrical simulation software like PROTEUS ISIS. The MIDE-written assembly language program was translated to machine code using OPWIN6, and then burnt into the microcontroller IC using a universal programmer. The 555 timer, which is connected in the
Astable mode, will be activated at the same moment by the microcontroller depending on the written program stored in its ROM. This will enable the buzzer to pulse and an alarm to sound with an LED flashing. The complete system operates on a 5 volts power supply which is obtained from the public mains. This design makes use of an efficient and low-cost technology
for controlling the appliances thus minimizing the power wastage. The results showed that the developed system provided accurate temperature control with a deviation of less than 1°C, and precise timing control with a deviation

The study is focused on the measurement of temperature using fiber optic sensor using an OTDR to measure attenuation

In this study, remote sensing data were integrated into GIS softwares for lithological mapping. The Landsat 8 OLI data were processed in order to see the lithological distribution in Akoko Edo area, Southern Nigeria. To achieve this purpose, products of Landsat 8 OLI digital data such as false color composite images (7, 5, 2 in RGB) and a band rationing image (6/7, 6/5, 4/2) were generated. Products of image processing improved lithological discrimination. Image classification was used to recognize and discriminate between the different rock units. In the result, four major classes were generated with two major geological features namely granite and migmatite with Bare earth surface and vegetation making up about 52% of the surface. The major geological features covered about 48% of the region. The band ratio classification using maximum likelihood classification was fairly accurate and matched the geologic map of Akoko Edo. The methodological approach used in this study for lithological mapping can be used to explore for mineral deposits, so more field works should be done to validate the gotten data and improve this method.

In this study, we looked at how we can generate random variables using beta distribution as our target distribution with the acceptance-rejection method. We also used the uniform distribution as our proposal distribution. The inability to invert the CDF is when acceptance-rejection method comes in place. Some simulations were made and results were shown

White Yam and Soya Beans is one of the commonly consumed carbohydrate staples. This work determined the Carbohydrate and Amylopectin content and glycemic index (GI) of white yam (Dioscorea rotundata) varying with soya beans (Glycine max). Yam tubers were obtained (peeled, sliced, washed) and beans were also obtained ( washed) then some yam and beans were dried, while some were boiled in water.
The cooked yam and beans sample were eaten by 1 individual about the age of 23. A glucometer was used to measure the blood glucose concentrations of the test individual before consuming the yam and beans diets and after the 15 th, 30th, 45th, 60th, and 90th, of consumption which was found to be 108mg/dl, 142mg/dl, 150mg/dl, 145mg/dl,120mg/dl, while for that of soya beans to be 91mg/dl, 105mg/dl, 115mg/dl, 100mg/dl and 111mg/dl. The average incremental area under the curve (IAUC) obtained from the recorded blood concentrations were used to calculate the GI of various White Yam and Soya Beans diets and the combinatrion of both is 210mg/dl for White yam and 585mg/dl for Soya Beans.
