Augmented Reality (AR) represents a promising technological advancement that this paper explores as a potential new educational tool. The integration of augmented reality applications into mobile devices facilitates interactive learning experiences for users. This integration transforms traditional printed educational materials into dynamic, interactive resources, aiming to enhance learner engagement, motivation, and overall educational outcomes. However, comprehending research trends and decision-making in this rapidly evolving field presents significant challenges. To address these challenges, this paper employs Bibliometrics, a method involving statistical and quantitative analysis of publications. Although augmented reality holds significant potential for higher education, limited studies have focused on its application, and scant attention has been given to bibliometric visualization. To bridge this gap, the paper utilizes VOSViewer, a bibliometric visualization software incorporating advanced machine learning techniques. The objective is to delineate the evolving landscape of augmented reality research from 2002 to the present and identify key research categories. Following an overview of the software’s functionality, artificial intelligence, and machine learning concepts, the study progresses to its practical stage. The research involves the retrieval of publications related to augmented reality from the Scopus bibliographic database, resulting in the identification of 730 relevant publications. After their retrieval, the paper conducts a comprehensive statistical analysis and employs VOSViewer for further processing. The culmination of the study involves the construction of bibliometric maps, visualizing keywords and terms extracted from the titles and abstracts of international scientific journal publications. The analysis of these maps yields valuable insights, observations, and conclusions, contributing to a better understanding of the current state and trends within the augmented reality research landscape. This approach facilitates informed decision-making and provides a foundation for future developments in the educational sector leveraging augmented reality technology conclusions.

This experiment was done to see the results of rearing Scylla olivacea crabs in cages of different size and embedding depth. The variables under considerations in the assessment were growth and survival rates and physical qualities of the experimental crabs. Additionally, this research aims to find out if the tested methods of confinement could produce better than the conventional culture practices. Three sizes of experimental cages such (45cm-l X45cm-w X60cm-h), (61.0cm-l X61.0 cm-w X75cm-h), and (76cm-l X76cm-w X90cm-h) and three embedding depths such as (30 cm), (45 cm), and (60 cm) labelled as treatment 1, treatment 2 and treatment 3 were tested. On the basis of cage size, highest mean on growth and survival rates of 279 grams and 88.90 % were obtained in treatment 3 followed by treatment 2 with 274.20 grams and 86.40 % and lowest mean of 269.31 grams and 82.25% was obtained from treatment 1. When assessed based on embedding depth highest growth and survival rates of 276.31 and 88.99% were obtained from treatment 3 followed by treatment 2 with 273.81 grams and 87.40% and treatment 1 with 272.71 grams and 81.25% being the lowest. Findings revealed that growth and survival rates obtained from three different cage sizes and three different embedding depths tested were relatively higher than that of what had been recorded and published. It was further noted that survival rates obtained were within the range (80-100%) considered as ideal. Growth and survival rates attained by different treatments were not significantly different. There were also no interaction effects attributed by size and embedding depth of experimental cages. Physical attributes of harvested mangrove crabs that were assessed based on the completeness of appendages, meat content, meat color, odor and taste were all at the mean value described as excellent. It is concluded that the methods of rearing tested improves growth, survival rates and mud crab physical qualities.

This study explored the lived experiences of second-career teachers in relation to their new professional roles and responsibilities in the public secondary schools. Using a qualitative methodology, specifically the phenomenological approach, the data were gathered from 10 participants through an in-depth interview. The participants were purposively selected with the inclusion criteria that the participants must be regularpermanent teachers, have taught in the division for at least two years, previously undertaken a degree in a field outside of education, and employed in a profession unrelated to education. The data were recorded, transcribed, validated, and analyzed using Creswell’s method of analyzing lived experiences. This data revealed four themes, namely: (1.) impetus for career shift, (2.) the hurdles of teaching, (3.) overcoming public school realities, and (4.) the gift of public school teaching. The impetus for career shift includes two subthemes namely: (a.) influence of significant others and (b.) the lure of better pay and privileges. The theme hurdles of teaching include four subthemes namely: (a.) struggling with the basics, (b.) dealing with changing behavior in changing times, (c.) the dearth of learning support in the public school and (d.) overwhelming clerical work. Overcoming public school realities include three subthemes: (a.) gaining wisdom from the older one, (b.) shelling-out of personal resources, and (c.) tapping first career experience. Lastly, the gift of public school teaching is a theme that describes the satisfaction and fulfillment of second-career teachers in public school teaching. Recommendations point to the need of implementing policies and practices and providing support for second career teachers’ professional development.

Solid wastes such as municipal wastes and agricultural wastes can pollute our environment if they are not disposed properly. In contrast, under manipulation, they can be changed into valuable products such as bio-enzymes and bio fuel. Bio-enzymes derived from kitchen wastes and agricultural wastes are cost effective and can be utilized in industry and agriculture with cutting in cost. This research is carried out to provide information about the cost-effective bio-enzymes with emphasis on their effect on germination and growth of seedlings of peanut (Arachis hypogea L. subsp. fastigiata). For bio-enzyme production, kitchen wastes such as onion-peels, cruciferous and citric fruits were used as solid substrate. Fermentation method was solid state fermentation with and without isolated microbes. The fermented formulation was that the mixture of three substrates at a weight/weight/weight ratio of 1:1:1 was placed into four airtight plastic containers containing the mixture of molasses and water at a volume/volume ratio of 1:10. Isolated bacteria, P1, P2 and P105 were introduced into three formulated mixtures, BE2, BE3, and BE4, respectively. All of them were fermented at 25℃ – 30℃ for three months. From this research, different hydrolytic activities of these four formulated bio-enzymes were investigated and their concentration being likely to impact on the germination and growth of peanut were examined in comparison to Hydro treatment used as negative control. Among BE1, BE2, BE3, BE4 and Hydro treatments, BE3 treatment at 1:200 dilution significantly showed the most effective activity on germination index, vigor index, branches per plant and pods per plant with 6.31 ± 0.29, 44.9 ± 23.63, 6.85 ± 0.15 branches per plant and 28.98 ± 0.07 pods per plant, respectively. This research shed light on the effect of bio-enzymes on peanut plant cultivation, particularly BE3, and it may become a potential for smallholder farmers.

The global energy consumption has surged from the minimal requirements of primitive societies to today’s extensive needs, which are being met primarily by fossil fuels. However, the environmental impact of these fuels, emitting greenhouse gases and contributing to global warming, prompts a reevaluation. Renewable energy is becoming an essential alternative energy source, and wind energy is one of the viable options. This study investigates the viability of wind energy in Northern Nigeria as a safer alternative to fossil fuel-based energy generation. Comprehensive wind data of two decades was obtained for six stations across three geographical zones in Northern Nigeria, detailing hourly readings at 10-meter and 80-meter heights. The study determined monthly and yearly wind speeds, as well as wind power density (WPD) at 10 meters per station. Results unveiled the regional distribution of mean wind speed, ranging from the highest in Jos (9.9 m/s) to the lowest in Yola (1.86 m/s). Employing diverse wind turbine models, including Acciona 70/1500 class I, GE 1.6-100, and Samsung 2.5/90, the study evaluated the Annual Energy Output and Net Capacity Factor. Notably, Jos exhibited the highest WPD (1402 W/m²), contrasting with Yola’s lowest (15.9 W/m²) at 80 meters. The findings indicate that Sokoto, Kano and Jos possess enough potential capable of generating electricity for integration into the national grid, while the remaining stations hold sufficient wind energy potential suitable for powering irrigation devices and other agricultural activities. It is recommended that the areas with high potential for wind energy should be harnessed into the national grid by the Government by providing funds to actualise this project on a large scale for the nation.
