One such application of IoT technology is in fire detection systems, which can help prevent and mitigate the devastating effects of fires on different types of facilities. The research presents a n IoT architecture for a fire detection system using small, low-cost cameras to collect surveillance feeds from large buildings. The data is uploaded to the cloud, where a Machine Learning algorithm detects fires in digital images. The proposed architecture consists of cameras, cloud, and clients, using an inexpensive camera for surveillance feeds and a convolutional neural network for image classification based on large datasets. However, the architecture's cloud component processes surveillance feeds and runs a Machine Learning (ML) model, utilizing computing resources for real-time data processing and continuous training for improved accuracy. Clients can subscribe to the data from the cloud and receive alerts in real-time when the ML model detects a fire in the surveillance feeds. There are significant benefits in comparing the proposed design to conventional fire detection systems. First and foremost, it is economical since the cameras used are compact, affordable, and simple to install around the building without the need for elaborate wiring or infrastructure. Secondly, it is scalable, as the cloud provides the necessary computing resources and storage capacity to handle large amounts of data, making it possible to monitor large structures with many cameras.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"292 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141692250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the recent index case of mpox following rapid spread from Africa to different continents, a critical appraisal of the disease to x-ray its dynamics in Africa is warranted. This study integrated a mix of scoping and systematic reviews to converse the epidemiology and biosecurity/environmental issues from one health perspective. Our scoping review used major scientific databases based on their relevance and reliability, while the PROSPERO-registered systematic review followed the PRISMA guidelines. Phylogeny analysis was performed to compare recent outbreaks of mpox with the existing genotypic information. The genetic analysis focused on the H3L gene that codes for envelope proteins involved in viral attachment. Transmission of mpox virus was reported mainly in four routes. Animals implicated include monkeys, squirrels, and pigs. Risk factors include age, gender, occupation, climate, travel, political instability, and vaccination status. Different circulating strains were reported with eight-point mutations found to occur in Africa. Observed clustering within the predominant West African (WA) clade and the recent outbreak strains corroborate the reports of WA clade in other non-African and non-endemic countries. Viral adaptation in the WA clade enhanced person-to-person transmissibility, spreading to over 100 countries. Hence, there is need to address mpox host-associated physiological and biochemical changes, the development of mpox virus-specific diagnostic kits and vaccines, and studies on the disease's socio-ecological, economic and psychological consequences.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"8 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141694585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, fluoxetine is a reproductive toxicant that induces sexual dysfunction. To determine the modulating role of aqueous extract of Hybanthus enneaspermus leaves on fluoxetine-induced gonado-toxicity, sixty healthy, sexually-responsive female rats (157.21 ± 6.89) were divided into six groups (A–F) comprising of 10 rats each. Group A (control group) were administered distilled water only, Group B-F received orally 15 mg/kg body weight (b.w) of fluoxetine prepared daily for 14 days for the induction of anti-oestrogenicity and subsequently received 0.5ml of distilled water, 20 mg/kg b.w of a reference drug (Tadalafil) and 0.5 mL equivalent to 250, 500 and 1000 mg/kg b.w of the extract respectively, orally, once daily (08:00-08:45h) for 7 days. Fluoxetine reduced serum oestrogen concentrations by 54.79% and significantly reduced (p<0.05) ovarian and uterine total protein, glycogen, cholesterol, the activities of alkaline phosphatase and acid phosphatase. The reductions were by (22.91%, 25.57%, 22.82 %, 15.09 % and 43.17 %) in the ovaries and (21.25 %, 26.9%, 7.20%, 16.82% and 29.85%) in the uteri of the animals respectively. In contrast, these reductions were overturned by the extract towards the control group. The extract at 1000 mg/kg b.w ameliorated the reductions of these oestrogenic indices. Hybanthus enneaspermus attenuated the deleterious effects of fluoxetine on the ovaries and uteri, restored sexual competence and promoted oogenesis. These may further lend backing to its widespread use in handling some sterility/infertility problems in women.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"19 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141702685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aimed to screen tomato varieties commonly cultivated in Nigeria to determine their host resistance status to Fusarium oxysporum. The treatments included Trichoderma asperellum, T. harzianum, and Mancozeb fungicide. Data recorded included the incidence and severity of the pathogen, plant height, leaf number, and fruit yield of the tomato plants. Tomato plants grown with Trichoderma sp. exhibited better performance in terms of average fruit yield count of 6.5 for T. asperellum and 6.7 for T. harzianum compared to the average yield of 1.7 fruit count for Mancozeb fungicide. The lowest disease incidence was recorded in the variety 3 (NGB00737) with a 5.81% incidence in the Mancozeb-treated plants. Conversely, T. asperellum-treated plants in variety 3 (NGB00737) had the highest disease incidence of 46.49%. For variety 4 (NGB00695), plants treated with Mancozeb had the least disease with a severity rating of 1. Similarly, variety 5 (NGB00725) plants treated with T. asperellum showed the least disease severity rating of 1. All other treated plants showed higher severity values of 4. The Trichoderma species also improved the fruit yield and some agronomic parameters of the tomato plants compared to the chemical control. Agro-business enthusiasts, commercial growers and local farmers are therefore encouraged to further exploit the potential of Trichoderma species as means of control for fungus-based diseases in tomato plants such as those caused by Fusarium.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"8 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141704249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on examining the prevalence of these infections among young adults seeking care at a secondary health facility at Olabisi Onabanjo University. Ninety samples obtained from study participants underwent screening using Enzyme-linked Immunosorbent Assay (ELISA) for both HBsAg and Dengue IgM. The participants, predominantly female, were aged between 15 and 30 years. The analysis revealed a 13.3% prevalence of Dengue IgM, a 4.5% prevalence of HBsAg, and a 4.4% prevalence for both infections. Regarding age distribution, the highest prevalence occurred among participants aged 15-20 years for both single infections and the co-occurrence of Hepatitis B and Dengue viral infections. Examining gender distribution, female participants exhibited higher seropositivity across all infection categories. Although not statistically significant, these findings lay the groundwork for a comprehensive surveillance study on the Hepatitis B and Dengue viral infections in young adults. This study provides valuable insights into the prevalence patterns of Hepatitis B and Dengue virus, offering a basis for further research and public health interventions in this population.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"61 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141712258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many plant samples have been adulterated intentionally or unintentionally during processing or even misidentified during collection. This study aims at authenticating and standardizing of Physalis angulata by carrying out Pharmacognostic evaluation, HPLC and GCMS analysis. Methodology: The dried leaves of Physalis angulata was extracted with 70% ethanol. Phytochemical screening (qualitative and quantitative screening) analysis was carried out on the ethanolic leave extract using standard method, while the chemical compounds were established with HPLC-DAD and GCMS and Pharmacognostic evaluation was carried out on the powdered leave. Results and discussion: Qualitative phytochemical analysis of the leave extract reveals the presence of flavonoids, terpenes, alkaloid, tannins and saponin while carbohydrate, glycosides and resins were absent. Quantitative phytochemical screening shows alkaloid present to be 2.4±0.4% and saponin 2±1.32%. HPLC analysis reveals the presence of quercetin, rutin, catechin and ferulic acid while GCMS reveals the presence of cyclohexene, Palmitic acid, 17-Octadecynoic acid, 1,2-Benzenedicarboxylic acid and Phytol. Total Ash content is (15.23±0.43) %w/w with acid insoluble ash of (1.16 ±0.28) %w/w, water soluble ash of (8.13 ±0.32) %w/w, moisture content (5.67 ±0.14) %w/w, alcohol soluble extractive value of (5.76 ±0.40) %w/w and water-soluble extractive value of (10.96 ±0.35) %w/w. Chemomicroscopic evaluation indicate the presence of lignin, cellulose, tannins, starch, calcium oxalate, oils and protein. Microscopy, fluorescence and organoleptic analysis were also documented. Conclusion: From this study, the presence of valuable phytochemicals has been established from the plant, while HPLC and GCMS revealed the identities of these compounds. Thus, the physico chemical parameters established for Physalis angulata in this study falls within the range approved by WHO (1992) for crude plant and extract.","PeriodicalId":476031,"journal":{"name":"Proceedings of the Nigerian Academy of Science","volume":"47 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141689943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
