Agronomic Usefulness of Anaerobic Slurry on Tomato (Lycopersicum Esculentum) Seedlings

Maliki Muniratu*, Esther Uwidia Ikhuoria

Current anaerobic digestion technologies are geared towards maximizing biogas yield and the subsequent use of the anaerobic slurries as soil amendments. However, only few studies have established the agronomic risk associated with the utilisation of anaerobic slurries. Therefore, this study evaluates the effect of agronomic use of anaerobic slurry on lycopersicum esculentum seedlings. L. escule...

Evaluation of the Effects of Weight Fraction on the Average Crystallite Size of ZnO Supported Bio-Waste Activated Carbon Composites

Onuoha David Chikaorama*, Egbe Evudiovo Apha Peter, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka

Metal nanoparticles are known to possess outstanding mechanical properties, relative to their bulk materials. However, due to large surface energy, nanoparticles tend to coalesce to each other, forming bulk particles and eventually deteriorate in quality. It is therefore, essential to immobilize nanoparticles on a support to help particles stay away from each other. This paper reports the effec...

Green Synthesis and Characterisation of Magnetite Nanoparticles Using Factorial Design of Experiment

Olasupo Olayode Adesola*, Abdulkareem Ambali Saka, Kovo Abdulsalami Sani, Abubakre Oladiran Kamardeen

Magnetite nanoparticles have been produced by green synthesis method. Aqueous extract of Mangifera indica leaves was used as reducing agent for co-precipitation of magnetite from iron (II) and iron (III) salts 3 in 1:2 molar ratio. Optimisation of the process was carried out using 2 factorial design of experiments taking into consideration stirring time of reaction medium, temperature and volu...

Development of a Low-Cost Fused Filament Fabrication (FFF) 3-D Desktop Printer

Oluwajobi A.O.*, Osunkoya Ruth Oluwseun

A low cost Fused Filament Fabrication (FFF) 3D printer was designed and fabricated, using in part local materials. The printer was based on the open source Replicating Rapid Prototyping (RepRap) design. The Arduino (Integrated Development Environment) IDE board was used for the implementation, and it uses the Repetier-Host software for the slicing and the printing operations. The print volume o...

Investigating Patients` Education on the Role of Footwear in Diabetic Foot-Care

TAGANG J. I*, Chen R. C

There is evidence that appropriate footwear plays pivoted role in the management of diabetic foot problems and inappropriate footwear causes foot ulceration. Therefore, this work was aimed at investigating how footwear could be used to prevent or reduce diabetic foot problem. Structured questionnaires were designed and used to gather information from diabetic patients. The study was carried out...

Profiling Biodiesel Produced from African Mahogany Seed at 1% NaOH Catalyst and Multiple Methanol Molar Ratios

Ishaya Zamani Donald*, PAM G Y, Kulla D. M., Abdulraheem Giwa

The need for new renewable energy resources and its utilization as sustainable solution for transport fuel, respiratory health and environmental problems drives this study. This study involved chemical profiling of African Mahogany (AM) methyl esters fatty acid (ME-FA) produced at multiple of two times, three times and four times seed oil to methanol molar ratios (MR). The key factors kept cons...

Preparation and Assessment of Biodegradable Polyurethane Foams from Sugar Bagasse

Lawrence Ekebafe*, Akpa F. A. Omolade, Olugbemide David A.

This study is focus on producing polyurethane foams that would have same or better properties compared to the conventional and still be able to undergo biodegradation upon disposal. Microfibers were isolated sequentially using nitric acid, sodium hydroxide and hypochlorite bleaching under different extraction conditions. The cellulose microfibers extracted were characterized for their compositi...
