They may be essential or non-essential to living organisms causing toxicity, environmental pollution or contaminate food chain. This research determined the hazard from ingestion of Moringa Oleifera leaves cultivated along River Ginzo, Katsina through the Estimation of Daily Intake of Metals (EDIM), Target Hazard Quotient/Hazard Index (THQ/HI) and Incremental Lifetime Cancer Risk (ILCR) from exposure to Co, Cu Pb and Ni in the leave samples obtained by random sampling. Heavy metals in samples were determined using Atomic Absorption Spectrophotometry (AAS) and analysed using Social Package for Social Science. The Result showed that levels of Co in all samples exceeded the 0.05ppm permissible limit in irrigation water. Values of Pb, Ni, and Cu and Ni in all soil samples exceeded the 0.05ppm, 0.30ppm and 0.05ppm USEPA, 2000 acceptable limits. Concentration of metals in leave samples are within the WHO/FAO 2014 acceptable limits. EDIM in M. oliefera were below tolerable daily intake, implying no health risk. THQ/HI for both essential and non-essential elements in leave samples were >1, implying no health hazard. ILCR showed potential risk of contracting cancer from the consumption of M. oleifera leaves grown in the study areas as Incremental Lifetime Cancer Risk values exceed the acceptable and negligible range of 10-4-10-6particularly of Ni (2.23E-2). As a result, measures should be put in place to prevent disposal of wastes containing heavy metals into River Ginzo used for irrigation purposes.","PeriodicalId":479809,"journal":{"name":"Fudma Journal of Sciences","volume":"183 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140483577","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}

Face mask use, diagnosis of asymptomatic infectious individuals, and isolation of infected individuals as control strategies are also incorporated. The model is shown to have two unique equilibrium states, namely: the disease-free equilibrium points and the endemic equilibrium point. The result from the stability analysis of the critical points is shown to be local asymptotic stable and also, globally asymptotically stable provided the basic reproduction number is less than one (, and the endemic equilibrium state is local asymptotic stable and also, globally asymptotically stable provided . Furthermore, results of the sensitivity index on for the different parameters of the model show that the recruitment rate and the effective contact rate are the most sensitive parameters and thus critical in disease management and eradication. Thus, efforts geared at reducing the recruitment of susceptible individuals and infection transmission rate will significantly eliminate the disease burden.","PeriodicalId":479809,"journal":{"name":"Fudma Journal of Sciences","volume":"81 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140483683","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}

Vector borne diseases are caused by viruses, bacteria, and parasites typically conveyed by mosquitoes. Certain illnesses transmitted by vectors include West Nile Virus, Malaria, Zika virus, Dengue fever, Rift valley fever, and Viral encephalitis induced by pathogens like bacteria, viruses, and parasites. The positive solutions of the model are presented and the theory of basic reproduction number was used to study the model dynamical behaviour.

The disease free and endemic equilibria states of the model were determined and investigated to be locally and globally stable.We incorporated the use of Insecticide –Treated Nets (ITN), Indoor Residual Sprayings (IRS) and condom usage as preventive measures in the presence of treatment. Numerical simulations show that complete intervention measures, that is, the use of ITN, IRS and condom usage while placing the infected on treatment have valuable impact on the spread of vector-borne diseases.","PeriodicalId":479809,"journal":{"name":"Fudma Journal of Sciences","volume":"149 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140484649","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}

In vitro spectrophotometric analysis was used to assess the methanolic extract of A. conyzoides' capacity to shield sickle red blood cells from lysis. Preliminary phytochemical screening of crude extracts of leaf, stem and root of Ageratum conyzoides tested positive for the presence of phytochemicals such as alkaloids, flavonoids, tannins, cardiac glycosides, saponins, steroids and triterpenes. The leaf extract caused significant (P<0.05) membrane protection with the value of 24.13±0.47% at 2.5mg/ml concentration, while the stem extract produced a significant (P<0.05) protective effect with the value of 29.13±0.47% at 2.5mg/ml.The root also gave a significant (P<0.05) membrane protective effect of 40.73±1.04% at 2.5mg/ml.

Given the aforementioned factor, assessing the Nigerian Navy Force's ICT maturity level is critical as this could offer helpful insight into how to successfully integrate ICT into the Nigerian Navy Force. This research work adopted the Small-size and Medium-size Enterprises ICT Maturity model in examining and measuring the optimal utilization of technology in Nigeria Navy Force. A questionnaire designed after ICT Maturity Model of SMEs containing forty-five research questions guided this project work. The questionnaires were afterward sorted and coded according to the responses from the 30 Senior Commissioned Officers, 30 Junior Commissioned Officer and 30 Non-Commissioned Officers that participated in this research survey using the indicator stage value in the coding process. The required ICT Maturity Indexes were extracted from the respective commands and were subsequently calculated using the Microsoft Excel Spreadsheet. Nigerian Navy Commands and unit were carefully selected and their ICT calculated to be significantly substantial with ICT maturity level at 0.58. This result analysis shows that ICT’s innovations and capacities are yet to be effectually and efficiently exploited within the Nigerian Navy Force. The research offers helpful insight into how to successfully integrate and measure the utilization of ICT potentials in the Nigerian Navy Force for its training and operations. The knowledge acquired would also be very beneficial for planning, budgeting, and setting funding priorities that will be specifically focused on the requirements area.","PeriodicalId":479809,"journal":{"name":"Fudma Journal of Sciences","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140483355","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}

Synthetic esters based on polyols and fatty acids possess suitable properties for lubricant applications, even at extreme temperatures. The current work investigates the oligomerization of fatty acid esters into biolubricant. The jatropha oil was esterified using recinoloeic acid and isobutyric acid over activated carbon from kaolin as a catalyst to produce biolubricant. Also, the carbon was prepared from kaolin through impregnation and activated with copper nitrate solution. The generated activated carbon was characterized using FTIR and XRF. The biolubricant (triesters) were produced via oligomeric fatty acid esters with recinoloeic acid under reflux at different reaction conditions and characterized using FTIR and GC-MS.
