(ABUAD Journal of Engineering Research and Development (AJERD), 2018) H. Adamu; O. A. Olugboji; O. Adedipe; J. Y. Jiya
In spite of the significance and availability of water, only an approximate value of about 1% is portable. Distillation processes which comprise evaporation and condensation in a box like machine called Solar Water Distiller was adopted for distilling unsafe to safe drinkable water in our homes. The design method adopted for the machine was energy method/balancing equation. The developed machine is a single stage distiller which is fabricated using local available materials. The heat energy required for powering the solar water distiller was 337.2 W/m2. This was the quantity of energy per unit time and area required for distilling the water based on average room temperature of 28.6 oC. The machine has capacity of average daily capacity of 28 litres as distillate water volume within 6.68 hours. It has design capacity of producing 4.2 litres per hour at minimum wind speed of 5.75m/s. The results show that produced machine has 75% efficiency with quality drinkable water that satisfied condition of Nigerian Standard for Drinking Water Quality NSDWQ (2007) rating.
INVESTIGATION OF MECHANICAL PROPERTIES OF POLYPROPYLENE FILM AS VACUUM PACKAGING MATERIAL FOR DRIED FISH
(ARID ZONE JOURNAL OF ENGINEERING, TECHNOLOGY & ENVIRONMENT (AZOJETE), 2023-09) I. A. Mohammed; O. Adedipe; J. Y. Jiya; A. B. Ayuba; K. T. Obanimomo; K. C. Bala
This study investigated the mechanical properties of three sets of polypropylene packaging films and existing dried fish packaging films and the quality of dried fish packaging in Nigeria... The polypropylene packaging films were produced in three batches A, B and C with thicknesses of 130μm, 150μm and 180μm respectively. The results showed that samples A, B and C had tensile strengths of 48N/mm2, 51.8N/mm2 and 61N/mm2 with Elongation at Break of 690.2%, 729.8% and 760% respectively. Also, the Dart Impact Strength of the samples were observed to be 191g/130μm, 208g/150μm and 231g/180μm respectively. Additionally, samples N and K (existing fish packaging films) had tensile strengths of 34.6N/mm2 and 31.2N/mm2 and Elongation at Break of 279.2% and 267.2% respectively. Furthermore, it was revealed that sample N exhibited better mechanical properties than sample K, while the produced polypropylene packaging films had the best mechanical properties among the samples tested. Using modern systems such as vacuum packaging and modified atmosphere packaging (MAP) techniques, fish packaging and storage was improved. This research is important in light of the significant increase in aquaculture activities in Nigeria due to increased fish production and government intervention in developing the sector, since it offers good moisture barrier properties, transparency and sealability with good cost efficiency and recyclability. It helps to preserve and protect the product’s quality, flavor and shelf life while providing a visually appealing package for consumers.

Tribological Properties of Canarium Schweinfurthii Shells as Frictional Materials for Automotive Brake System.
(Journal of Science Technology and Education (JOSTE), 2020-12) C. S. Ibeh; J. Y. Jiya; O. Adedipe; F. J. Usman; K. T. Obanimomo; J. B. Amuda
Friction material for automobile breaking system was developed using canarium schweinfurthii shell (CSS) otherwise known as African elemi. Tribological properties that direct or indirectly affect brake pad system such as thermal conductivity, water/oil absorption test, coefficient of friction, wear rate, hardness test, porosity, compressive, tensile strength, temperature, noise level generated and stopping time varying speed from 5.56 – 27.78 m/s was investigated. Experimentally developed produced brake pads using CSS were found to compete favourably with conventional brake pads and those from literature studies. The research finding using CSS indicates that CSS particle can effectively and efficiently replace asbestos in brake pad manufacturing.
