This study was carried out using vertical electrical sounding data and geochemical data to determine if there is a relationship between the aquifer vulnerability index and the water quality index in the Imo River Basin Southeastern, Nigeria. Some vertical electrical sounding data were collected using OMEGA SAS1000 Terrameter, and sixteen (16) water samples were collected from, both surface and groundwater around the three selected dumpsites from Owerri, Orlu and Okigwe areas. These two sets of data were used to evaluate the water qualities in the vicinity of the three active dumpsites. The DRASTIC index ranged between 59 and 199, and the spatial variation showed that 8.8% of the aquifer in the study area is highly vulnerable. 81.2% of the aquifer has a low vulnerability index. The water quality index in the study area showed both good and poor water qualities. The geospatial distribution of water quality index showed that 80% of the study area had good water quality, and the remaining 20 % of the study area had poor water quality. The bivariate regression showed a curvilinear, relationship between the aquifer vulnerability index and the water quality index Page(s): 01-13 Date of Publication: 28 August 2023 DOI: 10.51583/IJLTEMAS.2023.12801

Electrical installation and maintenance work is one of the trades in the curriculum of technical colleges. For the proper installation of electrical appliances, pupils are expected to develop psychomotor skills. Only the cognitive component of electrical installation work is evaluated by the NAtional Business and Technical Examination Board (NABTEB). According to the study, even though students graduate with good GPAs, they lack psychomotor abilities. Therefore, using flawed and unreliable instruments results in inaccurate assessments of pupils' improvement of psychomotor skills. Therefore, the study established the practical tasks in electrical installation and maintenance work to be completed by the students, validated the developed process assessment instrument in electrical installation and maintenance work, and also proved the reliability of the progressed process evaluation instrument in electrical installation and maintenance work. The developed instrument has provided a readily available process assessment instrument of high quality for the study. The following actions were advised for adoption by the study:1. For the purpose of certifying students, the external examination boards (NABTEB, NECO, and WAEC) should incorporate electrical installation and maintenance work skill assessment instrument items into their examinations.2. To train teachers of electrical installation and maintenance work how to apply the established electrical installation and maintenance work skill assessment instrument, the government should host seminars and workshops. 3. Technical education evaluators should examine their curricula, organize the material into pertinent activities, and create exams like to them in their particular subject areas using electrical installation and maintenance work skill evaluation instruments. 4. To evaluate students in electrical installation and maintenance work that is related to construction, teachers of electrical installation and maintenance work should be encouraged to use the created electrical installation and maintenance work skill evaluation instrument.

Generally, the architectural design and physical development of green walls in urban hemisphere has gone beyond aesthetics and traditional values. However, the multifunctional approach and quality healthcare contributions of green infrastructure are perhaps the contemporary trend urban dwellers value most. The economic, social, environmental and healthcare understanding of urban green spaces is on increase, as many environmental advocates affirmed that urban green spaces enhance sustainable city development. Conversely, this article concentrated more on public healthcare services or provision of green spaces in Nigeria urban environment, using Port Harcourt as a situation study. The healthcare benefit, environmental protection and sustainable city ideology of greens are imperative, but many have hardly been given any significant attention for smart city growth or development. Distribution of questionnaire for field survey constitute the study instrument while Statistical Package for Social Scientist (SPSS) served as the data analytical method and 5% of The sample was also derived from onscreen digitization of the neighbourhoods under investigation and the findings showed that green space sustain biodiversity, densification, environmental degradation, human health/wellbeing and mitigation against climate change are the healthcare services green spaces provide to the urban environment. However, population increase, urbanisation, poor physical planning/ zoning and government policy are the major determinants for the damages urban green spaces recorded as a healthcare facility. The analysis maintained that absences of green spaces in urban environment are responsible for poor urban morphology, loss of resilience/smart city, quality air, depreciation of property and neighbourhood value etc. As usage understanding, budget constraint and inappropriate cost benefit analysis are the challenges of urban green spaces in developing cities. The recommendations made by the research include the adoption of green space creation exercise. The minimum of two green spaces should be created and maintained per urban street schemes, participation of urban residents, corporate and non-government organisations in urban green spaces planning, development and the inspiration of mini green space for individual building plans among others. This will enhance sustainable urban healthcare facilities and development in Nigeria. Page(s): 33-39 Date of Publication: 13 September 2023 DOI: 10.51583/IJLTEMAS.2023.12804

Defined as a multiphase solid material with one, two, or three dimensions of less than 100 nanometers (nm), or structures with nano-scale repetitive intervals between the distinct phases that comprise the material, nanocomposites have over the years become one of the most popular areas of interest for current research and development in nearly all technical disciplines. This article provided a detailed definition of nanocomposites, before delving into in-situ polymerization, solvent-assisted solution blending, and molten or melt homogenization techniques which are the three types of nanocomposites’ preparation. After discussing the mechanical, electrical, flame retardancy, thermal, barrier, and rheological properties of nanocomposites, the study also discussed in detail the numerous applications of nanocomposites which include but not limited to the following: energy storage, civil structures, defence and aerospace, environment remediation, electronics, agriculture and food, automobiles and textiles, as well as biomedical medicine and drugs. The research later concluded by observing that the worldwide production of nanocomposites is estimated to exceed 600,000 tonnes, and is set to cover so many important areas within the next few years.

Folklore, culture, heritage, folk literature, arts and crafts of a country as known` pulse of the people’. Today, Folklore is practices in the remote areas only and centralized mainly to the rural people. In this age of globalization, we now identify several swings of changes in material folklore. Even, subject like trade and commerce are also influencing traditional cultures in multiple ways. In fact, many people of a country express their positive view towards the folk-culture, although a few of them cast their negative attitude to it. It is proved that; folk-material and culture is in threat all over the world but Bangladesh is an exception. It has a glorious and beautiful culture and heritage. Even though, it`s traditional expressions are facing various obstacles. In this study, we have tried to find of its importance in real life and how to confirm benefit of the folk-artist and their works from different complications. In this connection, valuation of different folk-material shas been shown. Besides, we have given some recommendations for the recognizing of the folk-artist and how-to development of folklore management nationally. This study prepared according to the Exploratory research methodology with field investigation and followed the anthropological approach.

Job satisfaction is vital for appropriate organizational behavior. Thus, employee attitudinal response to his or her organization influences job performance. It has been observed that quality passes among teacher trainees in our Public Teacher Training Colleges (PTTCs) in the country have been on the decline. The recent data reveals that out of 12,438 candidates who sat PTE Examinations in 2017, only 5 candidates scored distinctions, 4992 had credit, 886 had passed and 5932 failed. Furthermore, performance among teacher trainees has been noted to be declining since 2014given the ranking as per college means for PTE analysis 2016 results among the top 5 Primary Teachers Training Colleges. The objective of the study was to establish the influence of government policy framework factors on job satisfaction among Tutors on teacher trainee performance. A conceptual framework was used to show the interaction between study variables that influence job satisfaction among tutors and teacher trainee performance. The study established that government policy framework factors of job satisfaction among tutors had an influence on teacher trainee performance, especially the impact of the existence of properly coordinated government policy guidelines on the provision of teaching and learning facilities coupled with other related infrastructures in colleges. This was found to be crucial in motivating tutors at a statistically significant level whereby r= 0.807 at a p-value of 0.05. The findings of this study are recommended to be used by college administrators, the Ministry of Education, the Kenya Institute of Curriculum Development, and TSC to initiate and develop policies that could help improve job satisfaction among tutors in PTTCs for improved teacher trainee performance in the country.

In this paper, the Hazard and Operability Analysis HAZOP) studies carried out on the boiler section of Egbin Power Plantto validate the hazard and safe operations of the plant are presented. The aim is to identify all the corrective measures to improve safety and to provide refresher training for the operating personnel as well as to look at different scenarios that may come up as production is going on. The methodology used in carrying out the Hazard and Operability Studies was by using a well-structured and systematic method such as the combination of relevant keywords and parameters/variables like flow, temperature, pressure, level, etc. which resulted in deviations. These deviations were caused byequipment malfunctions, operational problems, and other factor. These resulted in consequences thatlead to low power output. The consequences of any action are the risks that should be avoided for the plant to continue to run. To overcome these problems, a tentativeactionwas provided which would make the operator take immediate action to mitigate the problems while maintenance would be carried out to avoid plant shutdown.

The drive of this paper is to explore the obstacles faced in new innovative product development design by Zimbabwean university learners in a bid to attain the United Nations (UN) Sustainable Development Goal (SDG) 12 “Responsible production and consumption” and the education 5.0 pillar “Innovation”. However, there is little progress toward the attainment of these related goals by students in the Zimbabwean university landscape and is fuelled by a lack of guidance and assistance from various stakeholders in the accomplishment of this objective. The study mainly concentrated on the encounters faced by university learners’ prior development of products that solve better the existing and emerging societal problems and at the same time fulfilling the UN sustainable development goal (SDG 12) “Responsible consumption and production” and Education 5.0 pillar “Innovation”. Open-ended questionnaire was used in this study to solicit in-depth data on the challenges university students encounter in new product development. Findings from the study indicated that Zimbabwean university learners are constrained by multiple challenges emanating from lack of monetary support from the Ministry of Higher and Tertiary Education, Innovation, Science and Technology (MHTEIST) and at the micro level either institutional level or agential conditions surrounding learning in the various universities of the country. These challenges include a shortage of resources, poor infrastructure, high student-lecturer ratios, lack of in-service training and staff development programs for lectures, and ineffective curriculum implementation among others.

World aquaculture production continues to grow to meet increasing demand for fish, especially as the fish catch has stabilized and is boosting aquaculture production as the only hope of meeting demand for fish. The aquaculture industry involves the farming of many species of fish of fresh or brackish origin and important freshwater fish species include the North African catfish, also called the African catfish (Clarias gariepinus). Its production is increasing as total aquaculture production is also increasing and its culture is spreading globally, with Nigeria officially declared as producing the largest annual aquaculture quantity of African catfish (clarias garipenous) globally at 3% of the total world production rate per year. There is a significant culture of African catfish in Ghana, currently approaching several decades with 1% of total world production. Ghana has been one of the largest producers of tilapia, pike, and catfish. This review focused on African catfish aquaculture in Ghana and Nigeria, comparing production and industry prospects in the two countries. This review indicates that Nigeria had a higher production rate of African catfish from the 1980s to 2018 than Ghana at the ratio of 3:1. Nigeria's catfish aquaculture industry has shown more significant advancements and expansion over the past two decades, Ghana has also experienced steady growth. Nigeria has established itself as a major player in the African catfish market, both in terms of production volume and international trade. Ghana's industry, although smaller, focuses on meeting local demand and has the potential for further development and expansion.

City planning with regard to green areas development can significantly offer a low cost and simple remedy to the impact of climate change in urban areas. This study examines green areas planning strategies as a means of mitigating urban heat island in Lafia town. The study discovered deficiencies in the development of green areas considering different land uses in Lafia town. The research used both primary and secondary data. Data deployed were used to calculate Normalized Difference Vegetation Index (NDVI); and the TIRS data were also used to derive LST. The boundaries of the urban area of Lafia town and the landscape indicators were interpreted and quantified based on high-resolution Google Earth images through manual interpretation based on the map of present land use. It is therefore recommended that green space should not be 300metres away from each other for optimum cooling. Also, vegetation and trees provides shade from direct sunlight radiation. The study further proposed a strategic base map of green areas planning to resolve the deficiencies and also made useful recommendations to stakeholders, policy makers and urban planners which when followed will provide green areas in Lafia town to enhance better health, a beautiful environment and urban heat island mitigation.
