Fufu, a product of cassava has been adulterated by processors. They add toxic substances to the soaked roots to fasten the fermentation days and make quick money. There is need to evaluate the effect of these fermentation agents on the microbial, pH and total titratable acidity (TTA) of the fufu dough. Fufu dough was produced with fermentation agents; kerosene, detergent and palm ash and also with a control without agent. They were wrapped in polyethylene bags, stored at ambient temperature and evaluated for storage and microbial quality in the Biochemistry Laboratory of National Root Crops Research Institute, Umudike, Nigeria. These samples were assayed for chemical and microbial qualities which include pH and TTA. The results showed that the pH values ranged from 3.70 - 6.80, and Total Titratable Acidity (TTA) values ranged from 0.004 - 0.048 %. The microbial analysis showed increase in fungal (2.1×108 (cfu/g)) and bacterial (1.0 ×106 (cfu/g)) counts as the storage time increased with the control having the least microbial load. The fungal isolates from the samples are Aspergillus niger, Aspergillus flavus and Penicillium spp, while the bacteria isolates from the samples include Bacillus spp and Staphylococcus aureus. Statistically, there were significant differences (p<0.05) in appearance of the fufu as storage time increased. The results from this study showed that the fufu with fermenting agents had higher microbial load than the control. It therefore encourages healthy practices among the fufu producers by stopping the use of fermenting agents to reduce the proliferation of pathogenic microorganisms in processed fufu.

The study evaluated capacity for extension workers’ outreach to crop farmers on climate change resilience and adaptation in Edo State, Nigeria. The study specifically described socio-economic characteristics of the extension workers; described capacities for outreach by the extension workers; identified constraints to building capacities for outreach by the extension agents and identified strategies to building capacities of the extension workers. A multistage sampling technique was used to select 69 extension workers. Data for this study were obtained through the use of structured interview schedule. Descriptive statistics and factor analysis were employed in the analysis. The results showed that majority of the respondents (50.7%) were Extension Agent (EA) followed by 29.0% who were Block Extension Supervisors (BES). The result reveals that 34.8% of the extension staff to have attended between 1 to 4 conferences in the last three years. About 44.9% of the respondents participate in workshops, training, seminars for extension workers and farmers. Majority (82.6%) of the respondents identified bush burning, massive deforestation and excess use of agro-chemicals in farming as the major causes of climate change. A major constraints to building capacities for outreach by extension agents was absence of well-defined agricultural policy (3.254). Restructuring of extension agents’ education and trainings was identified as a major strategy to building the capacities of the extension workers. It is recommended that agricultural extension policies relating to climate change need to be reviewed, among others.

This study examined the antioxidant activity as well as the safety profile of Azanza garckeana aqueous extract in female Wistar rats. Following the random distribution of 28 female Wistar rats (mean weight = 159.25 ± 3.32 g) into four (4) groups labelled (A-D) containing seven rats (animals) each, a daily administration of 0.5 mL distilled water was orally given to the rats in group A, while the aqueous extract of A. garckeana fruit pulp were given orally at 125, 250 and 500 mg/kg to rats in groups B, C and D respectively for 21 days. Some antioxidant activities as well as kidney and liver function indices were examined on the rat using established methods. All liver function indices assayed for showed no significant (p > 0.05) difference in comparison to the control. The concentration of liver enzyme revealed no significant (p > 0.05) difference in liver alanine aminotransferase, liver aspartate aminotransferase, lactate dehydrogenase and liver alkaline phosphatase at 500 mg/kg in comparison to the control group. Conversely, all kidney functions indices show significant increase (p < 0.05) following extract administration, indicating potential effects on kidney function. Significant decrease (p< 0.05) was observed in the level of kidney and liver reduced glutathione and kidney malondialdehyde while kidney and liver superoxide dismutase as well as liver malondialdehyde significantly increased (p<0.05). Overall, aqueous fruit pulp extract of A. garckeana shows no damaging effect on liver indices at the investigated dosage. However, it may have a significant side effect on the kidney due to the biochemical alterations observed in the kidney function indices at the investigated dosages.

In recent times, adverse environmental changes and the gradual reduction in fossil fuel deposits is making integration of renewable energy secure global attention. This paper therefore investigates the effect of high penetration of wind power on power loss and voltage profile of 52-bus, 330kV Nigerian grid. Modeling and simulation of the study were successfully done using the Continuation Power Flow method and Power System Analysis Toolbox in the Matrix Laboratory environment. The Ant Colony Optimization (ACO) technique codes were used to determine the best sites and sizes of Permanent Magnet Synchronous-based Wind Turbine Generators (PMS-WTGs) on the grid as nonoptimal placement and size of PMS-WTGs will result into active power losses and poor voltage profile. The ACO and power flow analysis indicated two load buses, Aladja bus and Yola bus as best sites for PMS-WTGs with optimal sizes of 100MW and 197MW respectively. The result shows a decrease in the system's active (42.1%) and reactive (43.9%) power losses while heightening voltage magnitudes of critical buses to statutory values and enhancing the grid power quality. The overall results indicate that integrating 297MW PMS-WTGs improves voltage stability and power loss reduction by maximizing system loadability and reducing line losses.

150x600 mm for the bending test and 150x150x450 mm for the shear test) specimens were used for this investigation. The concrete cube and RC beam specimens had SDA as a partial cement replacement within the range of 0%–10% by weight of cement at 2.5% intervals. 120 RC beam specimens were cast, followed by curing and testing at 28, 60, 90, and 180 days. Using the 4-point loading method, the bending and shear responses of the beams and associated parameters, like the formation and growth of cracks, were determined during the testing. The impact of SDA replacement on the characteristics of fresh and hardened concrete was also assessed using 105 cube specimens cast, cured, and tested at 7, 14, 21, 28, 60, 90, and 180 days. A concrete mix ratio of 1:1.3:2.4 and a constant water/binder ratio of 0.50 at optimum 5% SDA replacement produced (25 N/mm2 ) the required compressive strength. The results show that workability decreases as the SDA percentage increases. Generally, the values of concrete’s densities containing SDA in the mix were in the range of standard weight applications. At 28 days, samples up to 5% recorded a higher compressive, bending, and shear strength development rate than the control mix. The results show that cement partially replaced with up to 5% SDA can produce RC that meets the requirements for concrete for structural application.
