Abstract Abstract- This research work is focused on the failure analysis of Automatic Access Pedestrian Gate
Turnstile using SolidWorks Simulation Model. Failure analysis was carried out on both static and
dynamic failure of the system putting into consideration the yield stress, resultant displacement, failure
cycle, percentage damage, maximum strain and most importantly factor of safety. The results of Von
Mises stress analysis showed that a maximum value of 5.77Mpa yield strength was obtained. A
displacement of 0.257737m and a strain value of 2.03989×10-5 were obtained respectively. The fatigue
simulation damage factor was not up to 100% though is up to 50%. At the endurance limit or fatigue
limit, the SN curve flattens at 106 cycle. A safety of 61 was recorded with the system which is above 1,

Abstract Crushing of farm produce for easy storage and consumption is still a problem in most rural areas in Nigeria. Large tons of
food crops are lost annually in Nigeria as a result of unavailability of storage facilities. This necessitated the design of a
multi-purpose crusher to save crushing energy with minimal grain losses, being the primary aim of this study. The major
components of the designed crushing machine consists of a hopper, crushing chamber, shaft, hammers, screen, bearings,
discharge outlet and a 2HP electric motor. A number of tests were carried out with the designed crusher using 4.8kg of dry
maize and crushing efficiency of 85%, crushing loss of 0.15% and crushing capacity of 65kg/hr. were achieved as
optimum performances. From the test results, it was observed that the final crusher design had a higher capacity and
efficiency, and this produced finer end products compared to existing ones.

Abstract An increase in energy consumption is projected as a result of the world's unending
population growth. As a result, many are likely to rely heavily on fossil fuels. Biogas
is a viable choice because it is a green fuel and also sustainable. In this study, cow
manure (CM) and food waste (FW) consisting of yam and plantain peels were
collected, digested, and co-digested in the following proportions: 15%:85%, 25%:75%,
and 35%:65%. Five (5) AD reactors of the same capacity (25 liters) were used to digest
and co-digest CM and FW. The experiment was designed to discover the best
proportion variation of CM to FW that will yield the greatest results. The results
reveal that digestion of FW without seeding with CM takes a lengthy time to
complete. In addition, co-digestion of FW with CM serving as a seeding agent took a
shorter time. It was discovered that the percentage variation of co-digestion of CM
(25%) to FW (75%), as opposed to the percentage variation of co-digestion of CM
(15%) to FW (85%) and the percentage variation of co-digestion of CM (35%) to FW
(65%), resulted in the highest biogas yield.

Abstract Calcium oxide (CaO) holds significant importance as a catalyst and effective chemisorbent for
hazardous gases. This study presents the synthesis of CaO nanoparticles (NPs) using the hydrothermal
technique with snail shells' calcium carbonate (CaCO3) as the starting material. The hydrothermal method
offers several advantages over alternative approaches for producing metal oxide NPs, including its simplicity,
cost-effectiveness, and ability to operate at low temperatures and pressures. By utilizing waste materials like
snail shells as a precursor, the entire process becomes more economical, environmentally friendly, and
sustainable. The synthesized NPs were analyzed using various techniques, including Fourier transform
infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electron microscope (SEM),
transmission electron microscope (TEM), the Barrett-Joyner-Halenda (BJH) model for pore structure
quantification, Brunauer-Emmett-Teller (BET) for surface area calculation, and thermo gravimetric analysis
(TGA/DTA-DSC). XRD analysis confirmed that the size of the synthesized CaO NPs was 43.14 nm, determined
using the Debye-Scherrer equation. The transmission electron microscopy (TEM) image provided valuable
insight into the morphology of the nano-catalyst. The analysis revealed that the nano-catalyst displayed a
spherical shape, with an average particle size measuring 50 nanometers. The FTIR and XRD results
unequivocally demonstrated the successful conversion of calcium carbonate (CaCO3) derived from snail shells
into calcium oxide (CaO). TGA exhibited a significant weight loss peak at 700 °C, indicating the transformation
of CaCO3 into CaO. The DTA-DSC curve exhibited sharp endothermic peaks at 700 °C, suggesting a
decomposition reaction and the formation of a new compound. SEM images displayed porous, rough, and
fragile surfaces that became agglomerated at higher temperatures. In other words, the FE-SEM images of
NPs illustrated that the particles were predominantly spherical in morphology. Hence, waste snail shells hold
promise as a valuable source of calcium for various applications in different fields.

Abstract The low availability of reliable electrical energy in Nigeria; urban centres and rural area in
particular is alarming. At the moment, average Nigerians readily depends on non-renewable energy sources such as
fossil and wood fuel which is environmental unfriendly. However, wind energy is abundant, inexhaustible, affordable,
environmentally preferable, and equally sustainable. Hence, the objective of this paper was to undertake a comparative
estimation of onshore (Okada) and offshore (Okerenkoko) wind speed for potential wind energy access in Delta State,
Nigeria using appropriate standard methods. The outcome of the results obtained reveal that offshore areas generated
more wind speeds than the onshore area of Niger Delta. The percentage of onshore wind speed to offshore windspeed
was established to be 46% to 54%. Besides, offshore shows a better tendency of wind power generation against
onshore and this was due to high values of wind speed generated in offshore area. The amount of electricity produced
by a turbine is mostly determined by wind speed. Above and beyond, Okerenkoko has a better wind energy potential
than Okada and installation of wind turbine in Okerenkoko will help to boast a green sustainable renewable energy in
the region

Abstract This research work focused on the statistical optimization of pyridoxine in red guinea corn and millet composite. The concentration of pyridoxine (vitamin B6) was investigated under the following conditions: blending time (1.5-5hours), amount of red guinea corn (10-50g) and amount of agro residue (50-100 g) using Box-Behnken design. Statistically significant model (< 0.0001) was developed to represent the relationship between the response (concentration of pyridoxine) and the independent variables. The model showed a significant fit with experimental data with R2 values of 0.99. Analysis of variance (ANOVA) results showed that the concentration of pyridoxine was influenced by the blending time, amount of red guinea corn and amount of millet used. Response surface methodology (RSM) was used to optimize the concentration of pyridoxine and the optimization results showed that the maximum concentration of 61.36 µg/100g for pyridoxine was obtained at the optimum production conditions of blending time of 5hours, 47.45g of red guinea corn and 100g of millet. Also the recommended amounts of red guinea corn and millet composite for all groups as shown in table 11 were formulated in conformity with World Health Organization (WHO)/Food and Agricultural Organization (FAO) specification for recommended safe intake for all age groups, pregnant and nursing mothers with deficiencies in pyridoxine.

Abstract : This research employs response surface methodology, specifically Central Composite Design (CCD),
to optimize the process parameters for the effective production of biodiesel. Jatropha oil was utilized as the raw
material to minimize expenses. A nanocatalyst was utilized as a solid catalyst, developed from CaCO3 via waste
snail shells, offering advantages such as recyclability and improved catalytic activity during a transesterification
process. The developed nanocatalyst was analyzed using various techniques, including dynamic light scattering
(DLS), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, and Fourier-transform
infrared (FTIR). The BET analysis revealed a surface area of 5.1m2
/g and the Barrett-Joyner-Halenda (BJH)
analysis provided insights into the pore volume and diameter of the synthesized nano-CaO, showing values of
0.002556 cc/g and 1.1 nm, respectively, indicating the presence of both microspores and active sites on the
external surface of the nano-CaO catalyst. Biodiesel conversion was controlled by adjusting factors like the
methanol to oil ratio, catalyst weight, reaction time, reaction temperature, and agitation speed. A quadratic
model was established to explore the correlation between the independent variables and the biodiesel conversion
rate. The results showed a maximum biodiesel conversion rate of 96.73% under the optimal conditions: methanol
to oil ratio (6:1), catalyst weight (1.4 wt%), reaction time (60 min), reaction temperature (55 ?C), and agitation
speed (250 rpm). These parameters were determined through 32 experimental trials. The RSM technique yielded
impressive results with a determined coefficient of determination (R2
) of 0.9834, adjusted R2 of 0.8503, pre
dicted R2 of 0.8309, and a coefficient of variance (CV) 0.75%. Based on the analysis of variance (ANOVA)
findings, the model exhibits a high level of significance (p<0.0001), which is less than 0.05 and F- Value 29.71.
The study aims to enhance the yield and efficiency of the transesterification process, thereby increasing the
overall production of fatty acid methyl ester from Jatropha oil. This innovative approach efficiently generates
biodiesel from renewable resources, in a manner that is both environmentally friendly and maximizes the
effectiveness of the process parameters. The evaluation conform that the quality of the biodiesel met the stan
dards set by ASTM D 6751 and EN 14214.

Abstract Rolling of metals has found applications in automotive, construction, agriculture, railroads, housing, metal
furniture making, home appliances, electronic cabinetry, pipes and tubing etc. These have as well contributed to
human and environmental sustainability. Nevertheless, the applications of metal rolling processes and machines
have not been adequately harnessed in our locality due to unavailability of the rolling machine in small scale
industries, laboratories and workshops in institutions of learning in the region. Annealing heat treatment was carried
out on a mild steel round bar of 50 mm diameter and length of 200 samples. The samples were charged into an
SXL muffle furnace with an annealing temperature of 950oC. The mechanical properties and the microstructure of the
rolled mild carbon steel were evaluated. The results of the performance evaluation of the machine through
assessment of the metallurgical characteristics of the rolled products from the machine and assessment of
mechanical properties such as tensile strength and hardness of the rolled products from the machine showed an
increase in the tensile strength from 250.85 MPa to 258.85 MPa, an increase in the ultimate tensile strength from
535.88 MPa to 540.05 MPa, an increase in the hardness from 140 HV to 145 HV, and a decrease in the percentage
ductility of the mild carbon steel from 56% to 51%. Also, the optical micrograph of the rolled samples shows a coarse
microstructure of grain refinement from slipping and pilling of dislocations.

Abstract Alternative fuels, such as so-called electrofuels, could be a longterm answer given the increase in air traffic and the need to reduce
emissions. When referring to electrofuels, it is meant that they both
use renewable energy for fuel synthesis and emit no carbon dioxide.
In this study, five prospective electrofuels—n-octane, methanol,
methane, hydrogen, and ammonia—are compared to traditional
Jet A-1 fuel and considered with regard to their potential use as
aviation fuels. There are three key points that are highlighted. The
technological approaches, energy efficiency, and level of maturity
or research required for the manufacture of the electrofuel are
outlined. The physical-chemical characteristics are contrasted with
regard to specific energy, energy density, and characteristics that
are important for fuel combustion, such as autoignition delay time,
adiabatic flame temperature, laminar flame speed, and extinction
strain rate. Except for n-octane, the results indicate that the
physical and combustion properties are markedly different from
those of jet fuel. The findings outline how the various electrofuels
perform in relation to crucial factors like fuel and air mass flow
rates. The outcomes also aid in identifying the mixing
characteristics of each electrofuel's exhaust gas. N-octane
manufactured synthetically is viewed as a potential option for an
electrofuel in the future, even with a drop-in capability. The result
indicate that the autoignition delay period and laminar flame speed
percentage errors for the elecrtofuels and conventional fuels are
23% and 12% respectively. For the other fuels, further questions
need to be investigated before they may be used as electrofuels in
aircraft. Future hydrogen-ammonia combinations may be
particularly intriguing, but research in this area is still in its early
stages
