INTEGRATING THE USE OF PROJECT BASED LEARNING IN TECHNICAL AND VOCATIONAL EDUCATION: A CASE OF GSTC COMPUTER CRAFT DEPARTMENT IJEBU-ODE, OGUN STATE.

AbstractVocational and Technical Education (VTE) is one of the manpower development programmes of study that is attracting the attention of various countries around the world. Numerous studies on Didactics have demonstrated the effectiveness of student centered methods and strategies to improve results in terms of knowledge, skills, attitudes and values in Technical and Vocational Education and Training (TVET). With the continuous advancement of technology, computer technology has infiltrated...

Braking Pattern Impact on Brake Fade in an Automobile Brake System

Abstract. The importance of brake systems in automobiles cannot be overemphasized. Brakes are used in speed control of vehicles and do so by the conversion of kinetic energy into thermal energy. Better stopping performance has favored the disc brake system over the drum brake system and has found wide application in high-performance vehicles. Brake fade, caused by thermal overload has placed a limit on the permissible temperature at which braking systems can function, and it is the...

Modification of an adapted maize jab planter

ABSTRACTThe metering device is a key segment of planters that legitimately influence crop improvement and yield dependent on the presentation of the specific design. Metering device B (Teflon) is intended to minimize seed damage during planting while improving metering efficiency and field capacity. An improved local jab planter for maize seeds which is adjusted for farmers developing under two hectares has been structured, built and tried. The major components of the planter are hopper, seed...

Optimal Location and Sizing of Distributed Generation in Distribution Network Using Adaptive Neuro-Fuzzy Logic Technique

The growing gap between electric power generated and that demanded is of utmost concern especially in developing economy, hence calling for measures to argument the existing power generated of which DG is a more viable aspect to explore in curtailing this challenges; although been confronted with issue of location and sizing. This research applied Adaptive neuro fuzzy logic technique to optimize DG location and size. A 24 bus radial network was used to demonstrate this process and having a su...

IMPACT OF WEATHER VARIABLES ON ELECTRICITY POWER DEMAND FORECAST USING FUZZY LOGIC TECHNIQUE

Fuzzy logic, being a very robust artificial intelligence technique, was employed to forecast short term load in this work. The algorithm was demonstrated with the help of seven months average daily load data collected from Power Holding Company of Nigeria (PHCN). The outcome realized from the model or simulation illustrate that the projected forecasting technique, which propose the use of weather alteration such as temperature and humidity, gives load forecasting results with substantial prec...

Assessing the Benefits and Challenges of Distributed Generation in Nigeria Power Distribution Network

The growing concern for the need to reduce the gap between power generated and power consumed in Nigeria is on the increase. Many measures and policy have been geared by Nigeria Electricity Regulatory Commission and Ministry of Power to revamp the generation aspect of the country power sector but the impact is yet to be felt as the amount of power still generated is far below par compared to other countries. Nigeria average power generation stands at an average of 5800 MW. With the call to...

Insecticidal Efficacy of Some Indigenous Plant Species against Flea Beetles on Okra

AbstractLeaves and stems of castor oil plant (Ricinus cummunis), Barbados nut plant (Jatropha curcas) and Goat weed (Ageratum conyzoides) were investigated in the field during the 2018 cropping season at Umudike against Okra flea beetles, Podagrica spp (P. uniforma and P. sjostedti) for their insecticidal efficacy. NH47-4 Okra variety was used in the trial. The experimental design was Randomized Complete Block Design (RCBD) with seven treatments and four replicates. Results showed that the pl...

THE REASSESSMENT OF THE LEGAL INCIDENCE OF POWERS, RIGHTS AND RESTRICTIONS OF HOLDERS OF LICENCES/LEASES IN THE PETROLEUM SECTOR IN NIGERIA

There exists rights, powers and restrictions on the holders of the petroleum licences in the Nigerian Petroleum Industry, but these rights and powers are whittled down by the provisions of the Petroleum Act and other relevant legislations. The constitution vests the ownership of mineral resources to the Federal Government and by the Land Use Act, all lands are vested in the State Government.The rights and powers of the holders of the licences/leases can be revoked but must be done in accordan...

Agricultural Biomass Waste (cow Dung) collection, storage and use in Anaerobic Digestion with CHP

How Much quantity of dung needs to be collected to be used in an Anaerobic Digestion process to make it economically viable? How can the collected dung be used to generate electricity and heat in a combined heat and power? What CHP technology gives you the best electrical to thermal heat ratio? 

Drying and Particle Size Characteristics of Danta (Nesogordonia papavereria) and Hard Cross (Vitex doniana) Wood Sawdusts at Different Temperatures.

The drying and particle size characterization of Danta (Nesogordonia papavereria) and HardCross (Vitex doniana) hardwood sawdusts were investigated at temperatures 80 ºC, 90 ºC and105 ℃. The experimental drying data were modeled using eighteen existing drying models.The results showed that the modified Henderson and Pabis model offered the best fit to thedrying curves of Danta and Hard Cross sawdusts. The experimental data obtained from theparticle size distribution of both the samples we...

Production of Soy-Yoghurt by Fermentation of Soymilk with Lactobacillus Isolated from Nunu

The production of soy-yoghurt by fermentation of soymilk with lactobacillus isolated from nunu (a Nigerian indigenous fermented cow-milk) was studied. Soymilk was extracted from whole and dehulled soybean seeds and pasteurized. The fermentation was carried out with both the isolate from nunu and yoghurmet (a commercial yoghurt starter culture of Streptococcus thermophilus and Lactobacillus bulgaricus) as control. The percentage of soymilk inoculated was 70%, 80% and 100% of the broth. Soy-yog...

THE DESIGN AND IMPLEMENTATION OF RADIO FREQUENCY COMMUNICATION LINK

ABSTRACTThe aim of this project, the design and implementation of an RF communication link, is to design a communication link between a source and a destination and study the properties of the signal being generated by the source (generator). The area of interest in this work is how the signal suffers limitations like attenuation, interference and distortion etc and to observe how these limitations affect the smooth transmission of the signal as well as the amplitude of the transmitted...

Analysis Of Radio Propagation Characteristics For An Operative GSM Network

Abstract: This research work seeks to analyze the radio propagation characteristics of a GSM operative network using Makurdi as a case study. The analysis of radio propagation by a GSM operative entails the characteristics/ behavior of the radio wave between the transmitter and the receiver. An understanding of the radio wave propagation characteristics of an environment is a necessary condition for effective radio network planning which translate to the determination of the coverage stre...
