IN-VITRO PROPAGATION OF TOMATOES UNDER ASEPTIC CONDITION
In this study the major focus was to regenerate and produce multiples of Tomato (solanum lypersicon), with other desirable traits; in the absence of seed. The apical Meristem of tomato seedling was used as ex-plants for in vitro callogenesis. The ex-plants were washed with distilled water and sterilized by treating with 70% ethanol for 2 minutes and 20% of sodium hypochlorite for 20 minutes, ex-plants were thereafter washed 3 times with distilled water and then sterilized ex-plants were placed on MS medium modified with 3.0, 3.5, 4.0, 4.5, 5.0 mg/L 2, 4-Dichlorophenoxy acetic acid (2, 4-D) and incubated in the dark for callus induction and regeneration. The effect of different concentration of 2, 4-D on the callus induction from apical Meristem of tomatoes was evaluated under in vitro condition, 3.0,3.5,4.0,4.5,5.0mg/L 2, 4-D and were tested. The best optimum number of callus induction was MS medium supplemented with 4.5mg/L 2,4-D with an average percentage callus induction of (95.8%) and degree of callus growth (XXX) followed by MS medium supplemented with 4.0mg/L 2,4-D with an average percentage callus induction of (70.8%) and degree of callus growth (XX). The least was MS medium supplemented with 3.5mg/L 2, 4-D with an average percentage of callus induction of (56.8%) and degree of callus growth (XX). From the best optimum number of callus induction on MS medium supplemented with 4.5mg/L 2,4-D, the percentage of callus formation in each bottle was sub-cultured on fresh MS medium having concentrations of Zeatin (1mg/L) and 2,4-D (1mg/L) for regeneration. They showed average percentages of regeneration of 62.2% . Negative factors were eliminated.
TEACHING MATHEMATICS WITH THE AID OF AN AI CHATBOT FOR IMPROVING MATHEMATICAL THINKING SKILLS IN TERTIARY INSTITUTIONS IN GOMBE STATE
ABSTRACT
The researcher in this study analyses AI chatbots in order to facilitate the mathematical thinking capacity of tertiary students at Gombe State, Nigeria, which has low resources and a large number of students, in a region with limited resources.

EFFECT OF DIFFERENT LEVELS OF PHOSPHATE APPLICATION ON GROWTH OF SOME COWPEA VARIETIES (VIGNA UNGUICULATA L. WALP) IN MINJIBIR, KANO STATE, NIGERIA
Abstract
Phosphorus is important for cowpea production in many tropical African soils with inherent low phosphorus. Most farmers in Africa, however, do not have access to phosphorus fertilizer. Selection of cowpea variety that can produce good yield under low soil phosphorus or those with high phosphorus use efficiency can be a low input approach to solving this problem. In order to examine the possibility of the problem identified above, field experiment was conducted at the International Institute of Tropical Agriculture (IITA), Kano station farm located at Minjibir Local Government. The study aimed at assessing the differential phosphorus response of cowpea varieties that are tolerant to low phosphorus: IT97K-819-118, IT98K-205-8, IT97K-499-35 and IT99K-573-1-1. The study found that IT99K-573-1-1 gives the highest yield without phosphorus, followed by the IT97K-499-35, IT98K-205-8 and lastly IT97K-819-118. This concludes that there are varieties that can be carefully selected to mitigate unavailability of phosphorous fertilizer to farmers who wish to produce cowpea. The study, recommends that these potential varieties should be tested at multiple sites under various soil phosphorus condition to confirm the result.

ASSESSMENT OF BUSINESS SKILLS AND SELF-EFFICACY AS PREDICTORS OF STUDENTS’ ENTREPRENEURIAL INTENTION
Abstract
This study aimed to assess business educators’ perceptions of business skills and self-efficacy as predictors of students’ entrepreneurial intentions in Jigawa State Colleges of Education. The study used a structured questionnaire titled “Assessment of Business Educators’ Perceptions on Business Skills and Self-efficacy as Predictors of Students’ Entrepreneurial Intention” (ABEDPBSMSPSEI), which was developed by the researcher and validated by three experts from the College of Education Gumel and the College of Education and Legal Studies Ringim. The questionnaire used a four-point rating scale (Strongly Agree, Agree, Disagree, and Strongly Disagree) with assigned numerical values of 4, 3, 2, and 1, respectively. Items with a mean score of 2.50 and above were considered “Strongly Agreed” (SA), while items with a mean score of 2.49 and below were considered “Strongly Disagreed” (SD). The study found that business educators perceive skills in financial management, marketing, and strategic planning, as well as self-efficacy, as strong predictors of students’ entrepreneurial intentions. These findings align with previous research and suggest that educators recognize the importance of these factors in fostering students’ entrepreneurial aspirations. To address this issue, colleges should integrate business skills into the curriculum, enhance self-efficacy development, promote entrepreneurship education, provide resources and support for entrepreneurs, and monitor and evaluate the impact of interventions.

Research questions were raised and hypotheses tested using descriptive and inferential statistical tools. Motivation to go into private business included quest to gain more money, influence from family and the urge to be an independent person. Barriers such as lack of initial capital outlay (seed capital) and lack of guidance proved to be highly significant hindrances. Based on the findings, it was recommended among others, that all stakeholders should create and strengthen entrepreneurial education specifically for tertiary educational institutions in Nigeria.
ASSESSMENT OF HEAVY METALS CONCENTRATION IN EFFLUENT RELEASED FROM INDUSTRIES IN CHALLAWA RIVER, KANO STATE, NIGERIA
Abstract
Industrialization plays a crucial role in economic development, contributing to job creation, technological advancements, and overall economic growth. However, rapid industrialization often leads to environmental degradation. Industrial activities are major contributors to environmental pollution, particularly through the discharge of untreated or inadequately treated industrial effluents, which led to significant environmental challenges in the area. The Challawa River, which receives waste from the industrial estate, is a primary source of water for irrigation and, in some cases, for domestic use. Consequently, there is a heightened risk of heavy metal contamination affecting soil and water quality, posing potential threats to agriculture and public health. This study assessed the concentration of selected heavy metals—Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), and Zinc (Zn) in effluent samples released from the industries in Challawa Industrial Area of Kano State, Nigeria. The water effluent samples were collected from three distinct sites, prepared and analyzed using Atomic Absorption Spectroscopy (AAS) after nitric acid (HNO3) digestion. The results showed critically elevated levels of Cd (0.076 mg/L), Cr (22.07 mg/L), and Pb (1.770 mg/L), significantly exceeding WHO (2017) and NESREA (2011) permissible limits, thereby posing serious risks to environmental and public health. In contrast, Cu and Zn were within the WHO and NESREA permissible limits. These findings highlight the urgent need for regulatory enforcement, research, improved industrial wastewater treatment, and public health awareness.

DIGITAL ENTREPRENEURSHIP IN SOLVING UNEMPLOYMENT PROBLEMS AMONG NIGERIAN BUSINESS EDUCATION GRADUATES
Abstract: This study explores the critical role that digital entrepreneurship plays in addressing the ongoing unemployment issues that Nigerian business education graduates confront. Less than 20% of graduates are absorbed into formal employment, despite the high annual output. This is mostly because of skill mismatches and a lack of digital competences. The situation is made worse by structural elements such as population increase, economic reliance on oil, a lack of vocational training, and a lack of support for entrepreneurs. By giving graduates the necessary digital skills to provide self-employment options and stimulate innovation in the digital economy, digital entrepreneurship education presents a promising career path. The study underscores the urgent need for policy reforms and educational strategies that integrate digital entrepreneurship into business curricula, aiming to empower graduates to generate employment and contribute to sustainable economic development. Addressing infrastructural, pedagogical, and curriculum challenges is essential to fully harness this potential in Nigeria’s youth-driven economy.
ASSESSMENT OF MUSCULAR ENDURANCE AMONG THE STUDENT OF AMINU KANO COLLEGE OF ISLAMIC AND LEGAL STUDIES
Abstract
This study assessed the muscular endurance of students of Aminu Kano College of Islamic and legal studies, Kano, Kano State. Two research questions and hypotheses were formulated to guide the study. A survey research design was adopted for the study. The population for this study was 12, 072 students and a sample of 380 students were drawn through a multi-staged sampling procedure. The variable measured was muscular endurance. Simple frequency counts and percentages was used to organize and describe the demographic characteristics of the respondents; means and standard deviations were used for the physical characteristics of the respondents and inferential statistics of chi square was used to test the hypothesis to determine the muscular fitness of respondents and independent t-test was used to determine the difference between the male and female students. The results of the study revealed that students of the College have significant muscular endurance (ᵡ2 = 6.40, p = 0.001 < 0.05). Male students of the College do not significantly differ (t = 0.895, p = 0.372 > 0.05) from their female counterparts in their muscular endurance. Based on the findings of this study, the following recommendations were made that the physical activity of students should be a concern for the school in particular and the policy makers in general. Students of the College should be encouraged as much as possible to develop their physical fitness through daily physical activities because doing so will develop their physical fitness as well as free them from diseases, such as back pains and leg pains.

TRACE ELEMENTS CONCENTRATION OF COMMERCIALLY AVAILABLE DRINKING WATER IN KANO STATE
Abstract
Drinking water is important for the survival of all living beings. Many trace elements, both metals and non-metals, in drinking water are capable of causing human diseases if their concentrations exceed certain permissible levels. This study aims at measuring the concentrations of Zinc, Chromium and Cadmium in the commercially available drinking water in Kano state using Atomic Absorption Spectrometry technique. A total of 94 water samples were analyzed. The mean concentrations of the metals obtained in this study are within the maximum permissible levels for the drinking water recommended by the World Health Organization (WHO) and Standard Organization of Nigeria (SON). Conductivity and pH of the water samples were also measured to investigate correlation between their values and the concentrations of the three metals. A positive correlation is obtained between the metal concentrations and the corresponding conductivity values, while no significant correlation is seen between the pH values and the metal concentrations.
ENHANCING MOVIE RECOMMENDATION USING A MODIFIED ALTERNATING LEAST SQUARES ALGORITHM
ABSTRACT
Recommender systems are software techniques and tools that provide suggestions of items to be used by users, the suggestions are aimed at supporting users in various decision making process. The study tried to enhance a movie recommender system using a Modified Alternating Least Squares Algorithm to improve recommendations. An experiment was conducted to analyze the performance of the proposed design. The result shows that the algorithm effectively improves the movie recommender system. To validate system, we ran extensive experiments using Apache Spark with Movielens1M dataset. We compare the system with the other methodologies. The performance metrics used in the experiments are Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Precision and Recall. The results of the experiments show that the proposed Modified Alternating Least Squares (MALS) algorithm reduces the RMSE, MAE values compared to the existing recent ALS-based Algorithms, thereby improving the recommendation accuracy of the recommender system. As such, MALS is recommended to be used in training collaborative filtering recommendation systems, so as to result in generating best recommendations.
