ProjectUniversity of Port-Harcourt, Rivers State · 2025 · NDN PRJ-48626831764021316THE DETERMINATION OF NUTRIENTS IN INSECT FRASS(GRASSHOPPER)Daniella Nzubechukwu Nwachukwu · BSc · Animal and Environmental biologyThis study investigates the nutrient composition of grasshopper (Zonocerus variegatus) frass and its feasibility as an alternative fertilizer. Grasshoppers were collected from an open field and reared in an insectary at the University of Port Harcourt, where they were primarily fed elephant grass (Pennisetum purpureum).<br> Frass was collected over two months, systematically analysed, and compared to commercial fertilizers. Atomic absorption spectrophotometry (AAS) results revealed that grasshopper frass contains key plant nutrients, including nitrogen (3.01 mg/kg), phosphorus (1.16 mg/kg), potassium (2.108 mg/kg), copper (13.40 mg/kg), carbonate (10.80 mg/kg), and organic matter (1.24%). Additionally, the frass maintained a neutral pH (7.7),making it suitable for various soil types. These findings highlight the potential of grasshopper frass as an eco-friendly alternative to synthetic fertilizers, contributing to soil enrichment and sustainable agriculture.<br> However, the relatively low organic matter content suggests that combining frass with other organic amendments may optimize soil fertility. The study concludes that grasshopper frass has significant potential as a biofertilizer, but further research is needed to evaluate its long-term effects on soil health, microbial activity, and plant growth across different crop types. Future studies should also explore mass production, optimal application rates, and regulatory frameworks to support its widespread adoption in agricultural practices.

ProjectUniversity of Ibadan, Ibadan, Oyo State · 2025 · NDN PRJ-499745331764020961KNOWLEDGE, PERCEIVED SELF EFFICACY AND PRACTICE OF CERVICAL CANCER SCREENING AMONG WOMEN ATTENDING SELECTED HEALTH CENTERS IN IBADAN NORTH, OYO STATE, NIGERIATaiwo Oluwayemisi Ajayi · BSc · NursingIntroduction: Cervical cancer is the fourth most common cancer detected among women <br><br><br> globally with an estimated new cases of 529,409 per year. It is a serious public health problem <br><br><br> affecting women, which can be prevented if detected early with regular cervical cancer <br><br><br> screening. This study aims to determine the knowledge, perceived self-efficacy and practice of <br><br><br> cervical cancer screening among women attending selected health centers in Ibadan North <br><br><br> Local Government. <br><br><br> Methods: Health belief model was adopted to guide the descriptive cross-sectional study. One <br><br><br> hundred and ninety seven (197) standardized questionnaires including attrition rate were <br><br><br> distributed to women in the selected health centers of which sample size was calculated using <br><br><br> Taro Yamane formula. Statistical analysis was done using SPSS version 25 software, <br><br><br> hypotheses was tested using Pearson’s correlation test while descriptive data were presented in <br><br><br> frequency and percentages. <br><br><br> Results: The result revealed a mean age of 28.36±5.08; with more than half of the women aged <br><br><br> 21-30 (61.9%), Christians (56.8%), Yoruba tribe (74.6%). Analysis revealed More than half <br><br><br> (55.3%) of the women have poor knowledge of cervical cancer screening, Less than half <br><br><br> (53.8%) of the women have negative perceived self-efficacy towards cervical cancer screening. <br><br><br> More than half (84.3%) have never been screened for cervical cancer. More than half indicated <br><br><br> that the factors associated with practice of cervical cancer screening include cost, pain, fear of <br><br><br> positive outcomes, fear of the procedure, lack of approval, religion. Test of hypothesis revealed <br><br><br> that, there was no association between education, practice and level of knowledge of cervical <br><br><br> cancer screening at p value (0.805). A significant correlation was found between income and <br><br><br> knowledge level, (p = 0.032). <br><br><br> Conclusion: The study concluded that there is poor knowledge and negative perceived self-<br><br><br> efficacy towards screening, influenced by various factors listed above and therefore addressing <br><br><br> these barriers comprehensively is crucial for improving screening uptake.

ProjectOsun State University, Osogbo, Osun State · 2025 · NDN PRJ-496594531764020823EFFECT OF BRITISH STANDARD HEAVY EFFORT ON THE LATERITIC SOIL STABILIZED WITH STONE DUST ADMIXED WITH LIME AS A MATERIAL IN PAVEMENT CONSTRUCTIONOluwatobi Michael Lawal · BEng · Civil engineeringThis study investigated the stabilization of lateritic soil using lime and stone dust under British Standard Heavy (BSH) compactive effort to improve its performance in pavement construction. <br><br> Soil samples were collected from Iree-Obagun in Osun State and treated with varying proportions of lime and stone dust. To evaluate the effects of stabilization, geotechnical and microstructural tests including Atterberg limits, compaction, unconfined compressive strength (UCS), California Bearing Ratio (CBR), X-ray fluorescence (XRF), and scanning electron microscopy (SEM) were carried out.<br><br> The natural soil was reddish-brown with a moisture content of 18.23%, a specific gravity of 3.16, and a plasticity index of 17%. Classification results identified it as A-2-7(0) under AASHTO and SM under USCS, confirming its poor natural suitability for pavement works. Compaction results revealed that maximum dry density increased from 1.64 Mg/m³ to 2.34 Mg/m³ at 2% lime and 15% stone dust, while optimum moisture content decreased from 17.7% to 13.43%. The soaked CBR value increased from 34.45% for the untreated soil to 79.84% at the optimum mix, while the unsoaked CBR rose from 38.71% to 82.38%. Similarly, the UCS improved from 260.31 kN/m² to 410.97 kN/m². However, results indicated that strength declined when lime and stone dust were added beyond the optimum content.<br><br> XRF results showed that lime contained high calcium oxide, while stone dust was rich in silica and alumina. SEM images showed that the soil changed from porous to denser, with cement-like products (C–S–H and C–A–H). The study concludes that lime and stone dust are effective stabilizers for lateritic soils, with optimum performance achieved at 2% lime and 15% stone dust.

ProjectKenule Beeson Saro-Wiwa Polytechnic, Bori, Rivers State · 2025 · NDN PRJ-4951521231764020471CONSTRUCTION OF A DIGITAL SCHOOL BELL USING MICROCONTROLLER WITH TIMETABLE DISPLAYBarieeba Favour Goodluck · HND · Electrical/ Electronics EngineeringAbstract<br> Now a day’s many school/college bells are manually operated. Hence there is a huge demand of accuracy. In market there are many digital clocks available with bells but rings only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The benefit of this design is that the bell rings at the start of each period without any human intervention to a great degree of accuracy and hence takes over the manual task of switching on/off the college bell with respect to time. It uses Real Time Clock (DS1307) which tracks the real time. The scheduled time results are related with that of a clock, conversely, some drift is noticed, which is irrelevant. The microcontroller ATmega2560 is used to control all the functions, it gets the time through the keypad and stores it in its memory. When this programmed time equals the real time then the bell is switched on via a relay for a predetermined time. The bell ringing time can be edited at any time, so that it can be reused again and again at normal class timings as well as at exam times. Also it can be made password protected so that no unintended person can operate this system except for the operator. For this a microcontroller has to be programmed using the C language or assembly language for controlling the circuit.

ProjectUsmanu Danfodio University, Sokoto, Sokoto State · 2025 · NDN PRJ-194353831764020418THE IMPACT OF TAX AUDIT ON REVENUE GENERATION IN SOKOTO STATEAliyu Abunakar · BSc · AccountingABSTRACT<br> The study investigated the impact of tax audit practices on revenue generation in Sokoto with its specific objectives such as to determine the relationship between tax audit practices dimensions and company income tax. The population of the study consisted of tax offices Sokoto State, Nigeria with 20 staff of Federal Inland Revenue Service (FIRS). The sample size for the study consisted of 20 staff of FIRS which was determined using Taro Yemane formula for sample size determination. Primary data were collected from respondents using the questionnaire instrument. Pearson Product Moment Correlation Coefficient was also used with the aid of Statistical Package for Social Sciences (SPSS) version 23.0 to test null hypotheses. The findings of the study reveal that desk tax audit and field tax audit have a positive relationship with company income tax. The study therefore recommends that tax authorities should not concentrate only on desk tax audit but also on field tax audit so that revenue leakages will be blocked and increase the level of taxpayers’ compliance. Finally, there should be regular tax audit practices by tax authorities in Sokoto. This will assist in increasing government tax revenue.
