ABSTRACT

The study investigated the Causes and effect of Examination Malpractice in Secondary Schools in Gombe Metropolis, Gombe State, Nigeria. The study adopted descriptive survey design. The population of the study was1021 comprises 17 principals and 1004 secondary school teachers in Gombe metropolis. A sample of 279 respondents was selected using proportionate random sampling techniques. Instrument used for the study was a structured questionnaire with a five-point Likert scale titled Causes and Consequences of Examination Malpractice Questionnaire (CCEMQ). It was validated by professionals in the Department of Educational Foundations and Curriculum, Faculty of Education, Ahmadu Bello University, Zaria. Pilot study was carried out and the data for the pilot study were analyzed using split halve method of reliability. Cranach’s Alpha was used to compute the reliability coefficient where 0.93 reliability coefficients were obtained. Descriptive statistics (mean score and standard deviation) was used to answer the research question and t-test analysis was used to test the null hypothesis at 5% (p <0.05) significant level. The findings revealed a significant difference in the opinion of principals and teachers on the causes and effect of examination malpractices in secondary schools in Gombe metropolis. It was concluded that having enough classrooms and furniture in schools, qualified teachers for subjects and effective supervision during examination did not cause examination malpractice. The study recommends among others that there should be regular pre-examination lectures, seminars, workshops for teachers and students on the evils inherent in examination malpractice. National and international examination board should share information on new threat to examination security and procedures for counter reacting malpractices.

ABSTRACT

This paper presents the design and implementation of a digital energy meter with a remote transceiver that will accurately measure and calculate the amount of energy consumed by a certain facility while displaying its cost. The energy meter provides the utility company and consumer with regular status of the meter on a predefined interval and also disconnects the facility when requested so as to increase the efficiency of energy management. The meter, having a measuring capacity of minimum and maximum loads of 2 mA and 80 A respectively, could increment time with its inbuilt timer and counter subsystem in the microcontroller based on the embedded system code written into it. The meter with its communication facility aided with SIM800l module could be remotely monitored and controlled. This was demonstrated by sending off, on and watts commands via SMS. The energy meter responded to the commands as expected.

ABSTRACT

This paper highlights electronic voting technology which can be deployed to reduce malpractice commonly prevalent during voting exercise. A careful analysis of biological traits involving fingerprint and facial recognition for verification and identification is presented. This involves the development of java programming codes for face recognizer and fingerprint scanner. Facial recognizer makes use of software that compares one image with another image and produces a score that measures how similar the images are to each other. Fingerprint scanner involves the development of a biometric fingerprint system using sensor module, feature extraction module, matcher module and system database module. It is shown   here that finger print used as biometric verification is better than using facial recognition.

ABSTRACT

Three reference evapotranspiration (ET_o) models and one measured / observed (ET_o(m)) were compared using percentage format. Among them the standardized Penman – Monteith model given by Food and Agricultural Organisation (FAO), hereby refer to as FPM 56. One empirical temperature based and one empirical radiation based is among the models used to predict reference evapotranspiration in the semi – arid region of Nigeria. The three models and the observed model were compared to the standard ETo table, alongside the ET_o modelled by the FPM 56. The results showed that percentage modelling approach could be used as an alternative to modelling ET_o, and again that the Allen’s standard ET_o table is good comparison format when evaluating ET_o, apart from the normal use of the modelled value within the research work itself, which may not provide the appropriated water requirement for the agricultural field or the need that satisfies the environmental water requirements. The empirical models predicted better results for the semi – arid region closest to the standard ET_o table. The results of the percentage statistical comparisons provided a confident statistical justification for the ranking of the compared models.

Nigeria is endowed with many natural resources, some of which are yet to be fully utilized. Amongst the many natural resources found in the country is coal, which also has the potential of being a source of methane; commonly referred to as coal-bed methane. Coal-bed methane is a form of natural gas extracted from coal beds. Natural gas, which is predominantly methane, is fast becoming an essential source of today’s energy demand. Coal-bed methane (CBM) will not replace other fossil fuels in Nigeria but it will be burned in addition to the oil, coal and gas that have already been discovered to complement them. Hence, this study has presented several reported developed methods used to extract coal-bed methane, an attempts a recommendation of her application in Nigeria. Three methods of extracting coal-bed methane were examined in this study; which is pre-coal mining also known as Coal Seam Gas (CSG), Underground coal mining and Underground Gasification of Coal (UGC). The method recommended is the CSG method; the CSG distinctions have been noted over the other means of extracting methane from coal. The quality of methane that CSG method provides and the availability of the technological requirement make it more applicable to Nigeria coal deposits.

ABSTRACT

In this study, 90 fingerlings of Clarias gariepinus were divided into six treatments of five fish each. The different groups were exposed to the different concentrations of 0mg/L, 2mg/L, 4mg/L, 6mg/L, 8mg/L and 10mg/L for a period of 96 hours. The experiment was triplicated. The results revealed that all the fish of treatments exposed to 0mg/L of Hgcl₂ (control) survived whereas all the fish of treatments exposed to 8mg/L and 10mg/L died. The determination of 96 hours LC₅₀ was carried out by computing the mortality result in probit program of SPSS. The median lethal concentration was 0.55mg/L with lower and upper confidence limits of 3.188mg/L and 6.96mg/L respectively. Also in this study, the histopathological alteration in the muscle tissue of Clarias gariepinus caused by the mercury chloride were observed. After 96 hours of introducing different concentration of mercury chloride of the determination of 96 hours LC₅₀. The control (0mg/L) shows the fish skeletal muscle tissue with evenly sized muscle bundles displaying typical but less obvious cross striation as well as thick intermuscular connective tissue while the highest concentration (10mg/L) compared to 0mg (control) shows there is severe variability in muscle bundle size, accentuation of cross striations and severe reduction of muscle density with prominent myonecrosis as well as moderate thinning of intermuscular connective tissue.

ABSTRACT

Design of tank water level control system for automatic sprinkler irrigation was carried out to monitor water level in the tank and to control the pumping process. The system was designed such that when the water in tank is below minimum, the pump will automatically activate and refill the tank and also sprinkle the water within the giving interval of time. The Water Level Control System using non-contact Sensor was designed and constructed around microcontroller (ATmega16A) utilizing non-contact water level sensor called ultrasonic sensor (HC-SR04). The performance of the constructed system was evaluated. Result showed that mean experimented volume of water level in the tank and actual volume of water level in the tank were 8.0 and 8.11 litres, which had correlation coefficient value of 0.90. The automatic sprinkler reveals that, the initial delay from the system was 90 seconds before the sprinkler activate and sprinkle water for 10 seconds. This indicate that there was higher time delay at the initial time while the sprinkler continue to activate and sprinkle the water for every 10 seconds interval with system delayed at 25 seconds interval, respectively. The efficiency of the system designed was 98.4%which showed that the automatic sprinkler irrigation system can be used by farmers to monitor water level in the tank and control the pumping process to enhance efficient use of irrigation water to increase crop yield.
