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...

Structural and Optical Properties of Ag-Decorated ZnO Nanoparticles Synthesised via Hydrothermal Method for Optoelectronic Devices

M. I. Kimpa*, Muhammad Mustapha Kpanje, Haruna Isah, Abdullahi F. M, Ahmad Alhaji Abubakar, Y. Titus, K. U. Isah

Zinc oxide (ZnO) nanoparticles have attracted considerable attention due to their wide bandgap and excellent physicochemical properties, making them promising materials for optoelectronic and photocatalytic applications. However, intrinsic defects such as zinc and oxygen vacancies introduce mid-gap trap states that promote charge carrier recombination, thereby limiting their performance. In thi...

Production of biodegradable grease from Atili (Blackdate) oil

MAINA N. S*, Israel J. J

The work was aimed at the production of biodegradable grease from Atili (Blackdate) Oil that will be environmentally friendly. The grease was produced by mixing and blending of the base oil (Atili oil) with a mixture of calcium hydroxide and the stearic acid at 90oC which was then slowly heated to 190oC for about three hours to obtain the desired product. Three sets of the grease were produced ...

Study on the Thermal Properties of Epoxy Resin Reinforced with Arylidene-based Polybenzoxazine

Abdulrahman Musa*, Hamza A., Muhammad Abubakar Lawal

In this study, a new bis-arylidene derived benzoxazine: 2,6-bis((3-(2-hydroxyethyl)-3,4-dihydro-2H-benzo[e]  [1,3]oxazin-6-yl)methylene)cyclohexanone (HEB) was synthesized from its precursor: 2,6-bis(4 hydroxybenzylidene)cyclohexanone (BCH). The BCH was obtained as an aldocondensation product of cyclo hexanone and 4-hydroxybenzaldehyde, in an acid catalysed organic medium. Both HEB and BCH were ch...

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...
