| The effect of pre-treatment of mackery (Scomber scombrus) on oil recovery and quality was investigated. Fish oil was extracted using the screw expeller press after heat pre-treatment of the fish sample. The effect of cooking temperatures and cooking times was evaluated. It was observed that the oil yield has a positive relationship with cooking temperature. The oil yield increased with increasing cooking temperature at all the cooking times investigated and also increased with increasing cooking time from 5-15 minutes and then decreased for 20 minutes cooking time at all the cooking temperatures investigated. The results revealed that a highest yield of 22.8 % was obtained when the fish was treated at 90 0C cooking temperature for 15 minutes. The lowest... |

| An investigation was carried out on the effect of expeller press parameters such as choke clearances (1, 2 and 3 mm), screw clearances (1, 2 and 3 mm) and screw (worm) shaft speeds (50, 60 and 70 rpm) on fish oil extraction. The oil extraction rate and extraction efficiency had a negative relationship with choke clearances and screw clearances but had a positive relationship with screw (worm) shaft speeds. The oil extraction rate and extraction efficiency were found to decrease with increase in choke clearances and also decreased with increase in screw clearances. Increase in screw (worm) shaft speeds from 50 to 70 rpm was observed to increase oil extraction rate and extraction efficiency. The extraction loss had a positive relationship with choke... |

| The aim of the study was to assess the effects of groundnut shells on soil properties, growth and yield of maize. The study was carried out in Jalingo, Taraba State, North-Eastern Nigeria in July, 2019. Treatments in the study were four doses of groundnut shells (0.0, 2.5, 5.0 and 7.5 t ha-1); arranged in a randomized complete block design, replicated four times. Each plot was 2.0 m × 2.0 m with 0.5 m gap between the plots and replicates. Crushed groundnut shells were applied on a dry matter basis at the rates of 0, 2.5, 5.0 and 7.5 t ha-1 28 days before planting maize. Seeds were planted on prepared land treated with crushed groundnut shells. Soil properties were determined at harvest, maize growth parameters were determined at 50% flowering and maize... |

| Engineering properties are very important in the design and manufacturing of processing machines. In this research work, the engineering (physical, aerodynamic and mechanical) properties of acha (Digitaria exilis) grains were determined as design parameters for the development of grain processing machines for the crop. The physical properties determined were length, width, thickness, arithmetic mean diameter, geometric mean diameter, roundness, sphericity, aspect ratio, surface area, projected area, volume, moisture content, one thousand seed weight, bulk density, true density and porosity. The average seed length, width and thickness were found to be 1.84 ± 0.055, 0.85 ± 0.023 and 0.75 ± 0.042 mm respectively. The average arithmetic and geometric mean... |

| A theory using mechanical expression was proposed from the physics of oil expression in a screw press to characterize a mathematical model. The general oil expression equation was solved for three machine parameters (choke clearances, screw shaft clearances and screw shaft speeds) which simulate the machine parameters effects in the overall screw expeller process. The mathematical model was validated by the experimental data obtained from pressing fish oil with a screw press, using regression analysis. The experimental oil extraction data was fitted to the model and the quality of fit evaluated. A good fit was indicated by correlation coefficient of 0.9983, coefficient of determination of 0.9967, absolute average percentage deviation of 4.8 %, coefficient... |

| The application of organic fertilizer to the soil is considered as good agricultural practice because it improves the fertility of the soil and plant quality. The aim of the study was to produce compost tea using poultry droppings, cow dungs and water leaf (Talinum triangulare) in a ratio 5:5:1 and evaluate its effects on soil properties, growth and yield of Amaranthus hybridus. The study was carried out in Jalingo, Taraba State, North-Eastern Nigeria in July, 2019. The experimental variables include control (no treatment), 1 kg of compost per 10 L of water compost tea, 1 kg of compost per 20 L of water compost tea, 1 kg of compost per 30 L of water compost tea, 500 kg ha-1solid compost and 500kg ha-1 NPK fertilizer. The treatment combinations were done in... |
