National Civil Aviation Policy Implementation in Nigeria: An Empirical Study

The study examined the various programmes put in place by the Ministry of Aviation towards the implementation of government policy on civil aviation and assessed the extent of implementation of the national civil aviation policy in line with the set goals and objectives in Southwestern Nigeria. The study utilized primary and secondary sources of data. Primary data were collected through the administration of questionnaire and conduct of in-depth interviews. In all, 193 copies of questionnaire were administered to the staff of Nigerian Civil Aviation Authority (NCAA); Federal Airports Authority of Nigeria (FAAN); Nigerian Airspace Management Agency (NAMA) and Accident Investigation Bureau (AIB) in the three selected States (Lagos, Oyo and Ondo) of Southwestern Nigeria. In-depth interviews were conducted on eight Directors in the four aviation agencies to complement data obtained through questionnaire. Secondary data were sourced from books, official publications, academic journals, newspapers, magazines and internet materials. Data collected were analysed using simple percentages, frequency counts, mean values, and rank. The results showed that adequate personnel training (84%) and the development of institutional infrastructures for aviation agencies (76%) were programmes put in place by the Ministry of Aviation towards the implementation of civil aviation policy. On the extent of implementation, the study however revealed that, technical personnel were not adequately trained for professionalism and efficiency in air operations (with a mean value of 3.582) and all necessary equipment, technologies and institutional infrastructures were inadequately provided to civil aviation departments and agencies to prevent and counter new and emerging threats (with a mean value of 3.144). The study concluded that government policy on civil aviation in Southwestern had been poorly implemented to date.

EDUCATIONAL SUPERVISION: CONCEPTS AND PRACTICE WITH REFERENCE TO OYO STATE, NIGERIA

Abstract This paper examined the concept and practice of educational supervision in its universal context. It was noted that the concept of educational supervision has changed over the years. In the 19 th and 20 th centuries, supervision was perceived to be synonymous with school inspection. Teachers in the school system were expected to carry out instructions and directives of supervisors without question. However, today's supervisors are more humane in their duties as a result of Human Relation Movement in practice. The paper also examined the concept of educational supervision with reference to Oyo State. In Oyo State, supervision in schools is carried out for a number of purposes among which are: grading of schools, subject inspection, checking of records among others. Problems to effective supervision in schools in the state were discussed and means of reducing the perceived problems were also highlighted. Educational Supervision is a branch of Educational Management. Supervision could be defined as a day-to-day guidance of all education operations, coordination of the detailed work and cultivation of good working relationship among all the people involved in the teaching-learning process.. Supervision is in a sense, the back-bone of educational improvement (Education commission). Supervision is provided by the inspectorate division of the ministry of education to help educators and educational administrators to do better jobs. This service provides educational leadership and guidance to various personnels in the field of education. Supervision is necessary in education to ensure uniformity and effectiveness of educational programmes it is required to promote teaching and learning in schools

Gravity Inversion of the Gongola Basin Fault Structures Using the Step Model

Gravity anomalies with step-like appearance are often attributed to fault structures. Analysis of gravity anomalies due to such structures is then tantamount to solving the four fault parameters: depth to the surface, sediment thickness, density contrast and the fault dip. In this research, a gravity inversion using the step model was carried out to simultaneously estimate the four parameters of the faulted bed. The model assumes a configuration that the basin is filled with homogeneous sediments. Three characteristic curves were adopted for estimating the fault parameters.Analysis of the residual anomaly profiles of the fault structures showed that the fault structures were independent of the strike length. The estimated depth to the surface and the sediment thickness yielded the basement depth. The basement depth obtained from the gravity profiles showed a maximum basement depth of 1.0 km in the south-western part, and 7.0 km in the north-eastern part of the project area. The estimated basement depth yielded plausible geological model that corroborates with depth obtained using seismic and well information. The computed density contrast was used in the determination of density contrast and rock density maps of the basin. This helped in defining the basin into zones of sedimentary, basement complex and granite pluton

Molecular Characterization of Three Cultivars of Tomato (Lycopersicon Esculentum L.) in South-West Nigeria Using SSR Markers

Molecular characterisation of local tomato cultivars – Ibadan Local (IbL), Ife and JM94/46 (JM) were assessed using simple sequence repeat (SSR) markers. Out of ten SSR primer pairs used, three primer pairs were able to differentiate amplified genomic DNA of the cultivars. Unweighted Pair Group Method Using Arithmetic Average (UPGMA) cluster analysis of the data showed a close relationship between IbL and Ife with a genetic distance (GD) of 0.067; Ife and JM had GD of 0.2 and JM and Ife had GD of 0.25

Training of trainer manual for production of Orange Fleshed Sweetpotato (OFSP): planting to harvesting

Sweetpotato (Ipomoea batatas) originated in Central America or north-western South America from where it was introduced to Europe, Africa, Asia and North America in more recent times. Sweetpotato is now cultivated in nearly all parts of the tropics and sub-tropics as well as in the warmer parts of the temperate regions (CIP, 2019). This is because Sweetpotato is a dry-land crop, tolerant to a wide range of edaphic and climatic conditions. It is more tolerant of cold than other tropical root and tuber crops, hence, it can be grown at altitudes as high as 2500 m. China is the highest producer of Sweetpotato in the world, followed by Malawi, Tanzania and Nigeria (FAO, 2023). In more than 100 developing countries (including Nigeria), Sweetpotato is a smallholder crop grown with limited inputs on marginal soils. The yields in these developing countries are therefore far below the average for developed countries. Sweetpotato is a rich source of calories, fibre, micronutrients and vitamins when consumed. Its bio-fortification (as a means of addressing Vitamin A Deficiency (VAD) through nutrition based approach) led to the development and release of Orange Fleshed Sweetpotato (OFSP). Orange Fleshed Sweetpotato (OFSP), rich in β carotene (pro-vitamin A), is one of the well established and documented bio-fortified crops in Africa. It is the only biofortified crop providing up to 100% of daily vitamin A requirements when consumed (Bouis and Saltzman, 2017). Just 125 grams of most OFSP varieties can supply the recommended daily allowance of vitamin for children and non-lactating women (300-700μg RAE). According to Ezeocha, et al. (2010), OFSP are naturally biofortified with β carotene. Its consumption has been reported to improve vitamin A status in children. It can serve as a feasible long-term food-based strategy for controlling VAD in children in developing countries (van Jaarsveld et al., 2005; Korieocha et al., 2009). Strengthening the value chain (production, processing, marketing, and consumption) of OFSP in Nigeria is a key opportunity for addressing malnutrition and improving rural livelihoods. Leaves and peels of OFSP can be fed to animals thereby reducing cost of production of such animals. These can generate additional source of income for the farmers

Conservation of plant genetic resources

Survey, collection and conservation are important starting points in the genetic resources impact chain and in sustainable environmental protection strategies. Collection of plant genetic resources provides materials for herbaria, field gene banks, seed banks and in vitro conservation which are all important and crucial for characterisation and evaluation of plant genetic resources for various human needs. Because only a small spectrum of genetic variability is apprehended during collections, in situ conservation is crucial for optimizing biodiversity conservation programmes.

Electrophoresis of crude protein of seeds of some genera of Annonaceae

Seeds of five genera of Annonaceae were collected from different latitudes and special ecological zones of Nigeria, the crude proteins were extracted and analysed by electrophoretic fractionation with a view to establishing whether they have evolutionary relationships and also to know the highest protein richness in them. 0.5 ml of each protein sample was loaded into the gel tubes. A current of 1.5 m A per gel was applied until stacking. The current was increased to 3 m A per gel. The electrophoresis was allowed to run until the dye front was about 1 cm from the bottom of the gel. The result shows that the band at 5.2 cm is common among the genera except in Dennettia tripetala. Intergeneric bands were observed between pairs of gnera in the family. The highest intergeneric band is between Greenwayodenron suaveolens and Xylopia aethiopica at 0.2cm, 5cm and 5.1. The presence of common bands among the genera of Annonacea shows evidence of common evolutionary origin in them. Key Words: Annonaceae, Electrophoretic, Ecological, Band Nigeria
