Physical and Aerodynamic Properties of African Breadfruit (Treculia Africana) Seeds

ABSTRACTPhysical and aerodynamic properties of African breadfruit (Treculia africana) seeds were studied at four moisture levels: 12.50, 15.00, 17.50 and 20.10% wet basis (w.b). As moisture content increased from 10.50 to 20.10% wet basis (w.b), the average weight, major diameter, minor diameter, intermediate diameter, geometric mean diameter, arithmetic mean diameter of the seeds ranged from 0.35-0.60g, 8.0-10.06mm, 4.04-5.00mm, 2.96-4.60mm, 4.52-6.03mm, and 5.03-6.55mm respectively. Also th...

Design of Urban Stormwater Harvesting and Application System (Case Study Nairobi CBD)

ABSTRACT The city of Nairobi was initially engineered to keep stormwater out of sight and out of mind. Unfortunately, that approach has turned a potential resource into a waste product and created new environmental hazards. Once the rain falls onto the impervious surfaces of the streets, sidewalk, parking lots and rooftops, it picks up any and all pollutants that are  in  its  path,  gathering  volume  and  speed  into  the  storm  d...

MODIFICATION OF THE UNN SWINE ENTERPRISE PLANNING AND MANAGEMENT SOFTWARE

Swine enterprise is one of the best options to choose when investing in livestock production, but has been suffering a big neglect due to lack of awareness and ignorance on the part of investors in most developing countries including Nigeria. Everything about swine enterprise depends on how they are managed as they do not demand much financially for their labour, feeding, housing and equipment selection and for other basic needs as compared to other livestock enterprise. Therefore, due ...

THE DESIGN, FABRICATION, AND PERFORMANCE EVALUATION OF A LOCUST BEAN BOILER

African locust bean is a leguminous plant that is rich in nutrients and is used as food condiment. The traditional method of processing this food condiment is mostly unhygienic; consume a lot of fire wood, human energy and time. Using traditional methods for boiling 33.7Kg of locust bean would take about 12 hours. This study attempts to mechanize the existing traditional methods of boiling  locust bean by designing, constru...

DESIGN AND FABRICATION OF WHEEL AND BRAKE SYSTEM OF A TIPPING TRUCK

ABSTRACTThe purpose of this research work is to design, fabricate and install a hydraulic brake system on a wheel system of an agricultural tipping truck. For an efficient functioning of the brake system some measures have to be strictly considered; the weight of the vehicle and the external load.The engineering materials used in the fabrication of the wheels system include metals, ceramics and polymerics.Despite the efficiency of the brake there must be routine checks and maintenance to ensu...

DESIGN AND CONSTRUCTION OF FOUR-WAY TRAFFIC LIGHT

ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with ...

EVALUATION OF THE EFFECTS OF FLOODING ON FOUR VARIETIES OF RICE (A CASE STUDY OF EZZA NORTH, ABAKALIKI, EBONYI STATE)

ABSTRACTFlooding has been described as one of the most important environmental factors determining the distribution of salt maize plants. We studied the impact of five water levels on the germination and establishment of the invasive cord grass spartina denifora. Plant house experiment was carried out to determine the effects of time and depth of flooding o the survival and growth of rice. Data showed that time and depth of flood had significant effects on the survival and growth of rice.&nbs...
