Model study of the effects of temperature variability on biogas production from cow dung and chicken droppings

Alfa M. I.^*, Igboro S. B., Wamyil F. B., Shaibu-Imodagbe E. M., Ishaq A.

The pressure upon many nations of the world especially in the developing economies is the attainment of the Sustainable Development goals, one of which is Environmental Sustainability. A shift from fossil fuel to renewable alternative energy such as biogas has been identified as a key strategy for attaining this. The production of biogas from various substrates via anaerobic digestion has been ...

Effects of Ingate types on Some Mechanical Properties of Cast Aluminium 6063 Alloy

Shittu M. D.^*, Owolabi B. M, Ibitoye S. A, Olawale J. O.

This study examined the effects of inner-gate (ingate) types on some mechanical properties of cast aluminium 6063  (Al-Mg-Si) alloy. In this work, rods of aluminium 6063 alloy were cast using top gating, bottom gating and parting  line gating designs. Ingot of 6063 aluminium alloy was melted using crucible furnace and poured into already pre pared sand moulds. The casting from each gating system d...

Mechanical And Microstructural Properties Of Al-Sic Auto Brake Disc Rotor Composite

S. I. Kuye^*, Oladerin Kolawole O, O. R. Adetunji, Makinde Victor O

Aluminium Matrix Composites (AMC) are combinations of aluminium alloy and other components usually non metal and commonly ceramic such as silicon carbide (SiC) and aluminium oxides (Al2O3) in order to improve the  engineering properties of the aluminium alloy. This research work examined the mechanical and microstructural  properties of Al-SiC auto brake disc rotor composite. Aluminium ingots were...

Effect of compactive effort on the geotechnical properties of metakaolin treated black cotton soil

IJIMDIYA S. T^*, Imam G, IGBORO T, TANKO A

This study examines the influence of compactive efforts on the geotechnical properties of compacted black cotton soil treated with metakaolin (MTK) to assess its suitability for use as a barrier material in waste containment application. Black cotton soil treated with up to 10% MTK (obtained from calcinations of kaolin) by dry weight of soil was used. The natural soil classifies as A-7-6(22) an...

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...

Effects of garment laundry activities on the slider lock and crosswise strengths of nylon coil zippers

Umaru S.^*, Kaisan M. U., Usman S., Abdulraheem Giwa

Zippers are textile fastening devices which are flexible and operate by moving a slider along two rows of inter-lockable elements. In Nigeria, the polyester and nylon coil type of zippers are the most commonly used and patronized by makers of female garments and dresses. Previous study on the strength of zippers in a region similar to Nigeria showed zipper failures were as a result of wrong ap...

Characterization and disposal of hospital wastes in some selected hospitals within kaduna metropolis

ABDULLAHI N I^*, IBRAHIM F. B, Abdulraheem Giwa

Health-care services in rural or urban settings inevitably generate wastes that may be hazardous to health or have harmful environmental effects. This paper therefore assesses the generation, characterization and disposal of hospital waste of some selected hospitals within Kaduna metropolis. Nine hospitals were selected for the study. The weight of waste generated in these facilities is measure...

Synthesis and characterization of chitosan from locust

ALANI O. A^*, Mohammed K. Yakubu, BUKHARI M. M, GADIMOH S.

Chitin was isolated from locust using a standard procedure as described in literature with slight modifications. Chitosan was then synthesized from the isolated chitin by treatment with 50% concentration of NaOH, the degree of the deacetylation obtained was 64.4% using Potentiometer Titration method. Both chitin and chitosan ash content and moisture content were then analyzed. They were then c...
