Abstract

Good soil is needed for public health and this research studies lead concentrations of tomato planted in different soil samples in Wukari, Taraba state, Nigeria (with 50mg/kg simulated and non-simulated contamination) labelled groups A-H. Two weeks-old tomato seedlings were transplanted to triplicates of soils pots labelled A: normal soil, B:Ginger treated (positive control), three negative controls; C:lead contaminated; D Spent Engine Oil (SEO) contaminated, and E:Pb+SEO containing soil, F:Lead contaminated+ginger treatment, G: SEO contaminated+ginger treatment, H:lead+SEO contaminated+ginger treatment. The lengths, circumferences and weights of 36 tomato fruits per plant pot were measured at random. Lead uptake and bioaccumulation were also assessed in tomato fruits derived from each group. Tomato fruits in group E weighed highest (15.41±7.81g) while those in group H had the lowest weight (12.02±6.69g). The longest and the highest average tomato fruit circumference were recorded in group D (5.61±2.66cm and 6.15±2.93cm) respectively. Conversely, group H presented the shortest mean tomato fruits with 4.19±2.45cm and lowest fruit circumference (4.49±2.34cm). Bioaccumulation of lead was highest in tomatoes of group E with 1.79±0.47ppm and the lowest was derived from group A:normal soil with 0.68±0.13ppm on average each. The lead concentrations of all groups exceeded permissible limits specified in WHO/FAO Standards (0.01 ppm) as well as the maximum allowable concentration of 0.02 ppm by EU and 0.05 ppm limit set by USEPA suggesting a public health concern.

Abstract

The concept of fuzzy sets was introduced by Zadeh (1965) which marked the beginning of the evolution of fuzzy mathematics. The introduction of uncertainty in the theory of sets in a non-probabilistic manner opened up new possibilities for research in this field. Since then, many authors have explored the theory of fuzzy sets and its applications, leading to successful advancements in various fields such as mathematical programming, model theory, engineering sciences, image processing, and control theory. In this paper, we aim to improve and generalize some common fixed point theorems in fuzzy cone metric spaces, an extension of the well-known results given by Saif Ur Rahman and Hong Xu-Li (2017).

Abstract

The main purpose of this study was to determine the attitude of vocational and technical education lecturers towards the utilization of Open Educational Resources for effective teaching and learning in Nigerian universities in northeast Nigeria. The study adopted a survey research design and was carried out in northeast Nigeria. The population of the study was 782 Vocational and Technical Education lecturers from 5 universities that offered Vocational and Technical Education in northeast, Nigeria. The study adopted Simple random sampling to select a sample size of 254 respondents using Krejcie and Morgan (1970) sample size table. Attitude of Teachers Towards Utilization of Open Educational Resources Questionnaire, (ATTUOER-Q) was used as a data collection instrument. The questionnaire was subjected to face validation and a reliability index of 0.91 was obtained using Cronbach Alpha. The data for the study was analyzed using mean and standard deviation to answer the research questions. The findings of the study revealed that the factors that influence VTE lecturers’ attitudes towards the utilization of OERs include technological infrastructure and readiness, educator capacity and awareness, and content quality and relevance among others; the study further revealed that to a high extent, lecturers in Nigerian universities are aware of OERs available for teaching and learning. The study recommended that Institutions should develop and implement comprehensive training programs specially tailored to the needs and conditions of vocational and technical education lecturers in Northeast Nigerian universities. And The National Council of Universities should recommend increased institutional support and resources to facilitate the integration of OER into vocational and technical education programs

Abstract

This research investigates various real-world applications of exponential functions that are present in a country or region. Our goal was to gain an understanding of the exponential function. The exponential function is most commonly used in the growth and decay model. An introduction to the exponential function opens the project. We have got some real-world applications of the exponential function in this project, including: a. population growth: b. compound interest; c. bacterial proliferation; d. an increase in internet users; and so on. This work is motivated by the works of [1-13].

Abstract

This study examined road environment as a predictor of road traffic accidents involving heavy-duty automobiles in northeast Nigeria. Survey research was adopted for the study through a structured questionnaire. 235 FRSC, Traffic Police, VIOs and Drivers were sampled for the study. Regression analysis was used to test the hypothesis with the help of SPSS v.25 software. The results indicated that road signs system, natural road environment, and road conditions significantly influence road traffic accidents involving heavy-duty automobiles in Northeast Nigeria. Consequently, it was recommended that the Federal Government should provide an adequate and functional road signs system on Northeast Nigeria highways.

Abstract

This paper assesses the development and benefits derived by rural communities in the study area surrounding a game reserve. Questionnaires were administered to residents of fourteen selected communities within the game reserve and to the staff of the park. Additionally, focus group discussions were conducted with ten residents from each of the fourteen rural communities. A total of 720 questionnaires were distributed to residents to evaluate the development and benefits received from the establishment of the game reserve, while 250 questionnaires were distributed to the park staff to determine the impact of NGO activities on the communities. Interviews were also conducted with key stakeholders, including ward-heads, village-heads, youths, and women leaders. The findings reveal that the primary developments and benefits received by the game reserve rural communities include the establishment of primary schools, clinics, health centers, construction of roads and culverts, drilling of boreholes and wells, and access to loans for income generation. However, the relationship between farmers and pastoralists is strained, particularly during the dry season when livestock damage crops due to scarce forage. It is recommended that the working relationships between the communities and the game reserve be improved to achieve the overall objectives of conservation programs in Nigeria.

Abstract

Introduction: Medicinal plants have been the basis of treatment of various diseases in African traditional medicine as well as other forms of treatment from diverse cultures of the world. Khaya anthotheca is a member of the family Meliaceae, a native to Africa. It is a medicinal plant widely used for several therapeutic purposes. Herein, phytochemical study, hyperglycaemic investigations was carried out on the methanol extract of Khaya anthotheca Stem-bark. Materials and Methods: However, 35 rats were distributed into seven groups to evaluate the anti-diabetic activity of K. anthotheca stem-bark methanol extract at the dosage range of 50-400 mg/kg/b.wt. The analysis was done using the software-SPSS one-way ANOVA at a significance level p<0.05. Results: The result of the anti-diabetic study reveals that extract elicited substantial (p<0.05) inhibition of hyperglycaemic. The plant Khaya anthotheca stem-bark methanol extract displayed profound (p<0.05) anti-hyperglycaemic action at the dosage of 200 mg/kg/b.wt, 300 mg/kg/b.wt. and 500 mg/kg/b.wt. against induced diabetic rats. Conclusion: This study therefore suggests the use of Khaya anthotheca as a hypoglycaemic agent and for treatment of diabetic. Further studies are needed to discover the bioactive constituent of the plant responsible for this anti-diabetic activity.
