Zinc oxide nanoparticles are commonly used in many technologies. However, they are believed to have negative effects on the reproductive system. This research aims to explore how vitamin C can help protect the testis and epididymis of Wistar rats from the harmful effects of ZnO Nps. A total of 30 rats were separated into 5 groups of 6 and given different doses of ZnO Nps and Vitamin C for two weeks. In the ZnO group, malondialdehyde levels in the testis increased. On the other hand, the ZnO only group showed a decrease in gene expression and antioxidant enzyme activities compared to the control group. However, oxidative markers were significantly mitigated after combined treatment of ZnO Nps and Vit C compared to the rats given ZnO Nps (p < 0.05). This study demonstrate the ameliorating role of vitamin C on toxicity of ZnO Nps. In there epididymis, significant increase were observed in the SOD, MDA, CAT, and GPX of the ZnO NPS and combined treatment of ZnO Nps and vit c when compared to the control ( p> 0.05). The study found that there was a noticeable drop in the number of live sperm cells when exposed to ZnO alone and ZnO with Vit C, compared to the control group. On the other hand, there was a notable increase in the number of dead sperm cells when exposed to ZnO Nps alone and ZnO Nps with Vit C. Additionally, there was a decrease in the movement of sperm cells when exposed to ZnO Nps alone and ZnO Nps with Vit C, in comparison to the control group. This research shows that ZnO Nps have a negative impact on sperm quality, as well as the functioning of the testis and epididymis

The need for sensory play in promoting fine motor skill in Montessori pupils has proven to be an excellent strategy to improve on the child's learning, as the teachers in Montessori schools strive to give the pupils a quality and more concretised learning experience needed for the proper growth and development of the children. This study was carried out to determine the impact sensory play has in promoting fine motor skill development in Montessori school pupils. Five research questions were used for the study; The study adopted the questionnaire to collect data. The sample for the study was a hundred (100) Montessori school teachers drawn from a total number of ten (10) Montessori schools in Benin City. A frequency distribution, percentage, mean and standard deviation was used to analyze data. It was concluded that sensory play activities along with sensory play materials are important vehicles for the development of fine motor skills. The study recommends that sensory play should be integrated into the classroom learning activities, with the teachers providing for several sensory materials to meet the diverse domains of every pupil, and providing a safe and conducive environment for learning while acting as a guide to the children's learning

With the consistent improvement in information Technology, especially artificial intelligence, many sectors have benefited from it. Education has an immense role to play in the quality of the individuals who will drive the world to the next stage in each generation. The implementation of AI in education aims to equip the student with a plethora of resources from which information and knowledge can be attained. Though it boasts about potential to revolutionize the educational sector, the danger of over reliance on it still exists, aside from that, role of a teacher isn't one that should be replaced by AI, because human interactions are a necessary part of being a human being as outlined by UNESCO. The report emphasizes the need to discourage students from using generative AI as a shortcut to completing tasks, assignments, and even projects. The aim of teaching students is not for them to just produce answers but to learn how to produce them by working hard and dedicating themselves to the pursuit of knowledge. This is the goal that the educational institutions hope to achieve, and creating a system that would increase the chances of achieving that goal should be embraced and utilized.

This study focuses on the linguistic place of an Ẹdo woman in language preservation. The aim of this research work is to gain a better understanding of the linguistic features of the Ẹdo language, and to explore the role of women in language preservation. The method used in carrying out this research was both primary and secondary. The data for this study was collected using oral interview with competent native speakers of Ẹdo. The data were collected from residents whose ages range from fifty years and above. The respondents were: old people (specifically women), Ẹkosodin Benin women and the researcher's mother and also documented data from secondary sources. The feminist sociolinguistic theory framework was employed for the analysis of the data. The analysis of the data reveals valuable insights into the ways in which women actively participate in language preservation efforts and contribute to the vitality of the Ẹdo language and culture. The study concludes that through
activities such as storytelling, singing traditional songs, and teaching cultural practices, women actively contribute to the transmission of linguistic and cultural knowledge to future generations, thereby playing a crucial role in language preservation efforts. The study is recommended to policymakers, educators, community leaders, and researchers interested in language preservation, gender studies, and cultural heritage

The apprenticeship system in Igbo land is a unique and ancient system of education and socialization, which has been in existence for centuries. The system, which is known as "Otu ndi Igbo" in the Igbo language, has played a vital role in the social, economic, and cultural development of the Igbo people. This paper will focus on the history of the apprenticeship system in Igbo land, with a case study of Onitsha between 1970 and 2010.1 The Igbo people are one of the major ethnic groups in Nigeria, with a population of about 40 million people. They are known for their entrepreneurial spirit and their strong sense of community. The apprenticeship system is a traditional way of learning and practising a trade or craft, and it is an integral part of Igbo culture. The system involves a young person (usually a male) being taken under the wing of an experienced artisan or businessman, known as the "master," for a period of training and practical work. The apprentice lives with the master and learns the trade or craft through observation, practice, and guidance

Undoubtedly, if the idea and practice of searching for peace is as old as then it follows that the history of wars and conflicts, which are its harbingers, is older. The recurrence and re-escalation of conflicts in various parts of the world, most especially in the developing states, has indeed made the word ‘sustainable peace’ an illusion. A lot can be said on the havoc wrecked by conflicts on the people and the devastating effects on the natural environment.1 Regrettably, all efforts made to put an end to conflict around the globe yield little or no significant results since war is a learning behavior and the proclivity of it has remained undefeatable. Put simply, the past and recent events around the world reveal that ethno-religious conflict, resources struggle, ideology and mistrust as ever before, still very much predominate in the contemporary world and therefore called for the need for peacekeeping forces by willing states under the auspice of regional and international organization, that is in a multilateral format.There is hardly any doubt that the United Nations Security Council remains the world’s principal body vested with the responsibility of maintaining international peace and security but rely on the willing cooperation of States and contribution of their armed force to serve as a third party between two warring parties. Peacekeeping operation began with the United Nations.

Polycyclic aromatic hydrocarbons (PAHs) have received significant attention due to their potential health and environmental impacts. Some are toxic and pose risks to human health and ecosystems. This study was conducted to determine the levels of PAHs in Oreochromis niloticus from Ogun river in Ajegunle, South-West Nigeria. Gas Chromatography with Flame Ionization Detector (GC/FID) was used to measure the concentrations of PAHs in the fish tissues, following United State Environmental Protection Agency (USEPA) methods. The objectives of the research evaluated the toxic equivalency (TEQ) of PAHs, toxic/hazard
quotient for PAHs, estimated daily intake with annual intake and cancer risk factor for PAHs in O.niloticus. Naphthalene had a low value in the fish sample analyzed and could be related to the fish species inability to absorb it irrespective of its presence in the water and sediments. Total PAH concentrations found in the fish sample exceeded the acceptable limit set by the European Commission (2 µg/kg Fluroanthene and Benzo(a)pyrene) for fish considered safe for human consumption. The quota for PAHs
ranged from 0.037% for Naphthalene to 73.97% for Fluroanthene. The continual consumption of fish from the river by the inhabitants could lead to bioaccumulation with adverse health implications since PAHs are carcinogenic, mutagenic and teratogenic. Furthermore, the high concentrations and the persistent nature of PAHs make the fish that inhabit the river unfit for human consumption.
