        Lesser known indigenous vegetables as potential natural egg colourant in laying chickens

        Abiodun, Bolu Steven,Adedeji, Aderibigbe Simeon,Abiodun, Elegbeleye Korean Society of Animal Sciences and Technology 2014 한국축산학회지 Vol.56 No.5

        Background: A six-week study involving two hundred and fifty (250) Harco Black layer birds at point of lay was conducted to investigate the effects of potential natural colorant on performance and Egg quality traits. The birds were assigned to five (5) dietary treatments, each containing supplements either of control, Baobab Leaf (BL), Waterleaf (WL), Red Pepper (RP), Canthaxanthin (CTX) at 40 g/kg feed and 50 mg/kg feed of natural and commercial colorants, respectively. Results: Performance records shows that there was no significant (p > 0.05) difference in feed intake across the supplements of Red pepper, Water leaf, Canthaxanthin and control diet, however, birds fed Baobab leaf treatment had a significantly lower (p < 0.05) feed intake value (94.07 g) when compared with other treatments. Body weight gain and Hen Day Production were not significant influenced (p > 0.05) by the dietary treatments, although laying hens fed Baobab leaf supplement had lowest mean HDP of 48.80%, while birds fed Red pepper and Water leaf supplement had an average value of 52.79%. There was no significant effect (p > 0.05) of colorants on egg external traits, compared with the control; birds fed Canthaxanthin treatment had higher mean egg weight (51.79 g), egg length (4.55 g), egg breadth (3.29 g); Red pepper treatment had highest mean shell thickness (0.29 g), however these differences were not significant (p > 0.05). Yolk height, Albumen height, Yolk index, and Haugh unit were not significantly affected (p > 0.05) across treatments. Yolk width was lowest (p < 0.05) in Baobab leaf treatment (2.54 cm); Red pepper, Water leaf and Canthaxanthin (2.89 cm, 2.62 cm and 2.89 cm respectively) were not significantly (p > 0.05) different from the control (2.73 cm). Yolk colour score was significantly highest (p < 0.05) in Red pepper treatment (7.50); Water leaf, Baobab leaf and Canthaxanthin ranged between 2.25-3.31 on the DSM yolk colour fan, Control treatment had the lowest yolk colour score (p < 0.05) of 1.31. Conclusion: The study showed Red pepper as a worthy alternative to commercial yolk colorant. Water leaf and baobab are not good substitutes for canthaxanthin as a yolk colourant.

        Awareness of Reproductive Health Risks, Sex Hormone Levels and Sperm Indices among Farmers Exposed to Pesticides in Akungba Akoko, Nigeria

        Mathias Abiodun Emokpae,Evelyn Apiriboh Yeiya,Mathias Abiodun Emokpae 한국환경보건학회 2022 한국환경보건학회지 Vol.48 No.4

        Background: The indiscriminate use of pesticides in Nigeria may have harmful effects on reproductive health of farmers. Objectives: This study assessed the awareness of reproductive health, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, estradiol, progesterone and sperm characteristics of male farmers occupationally exposed to pesticides. Methods: Eighty four male farmers were recruited for the study. Structured questionnaire was used to obtain the socio-demographic data. Blood and semen samples were collected from the subjects in the morning for hormonal assays and semen analysis using enzyme linked immunosorbent assay (ELISA) method and SQAV sperm quality analyzer. Data were analyzed using chi square, Student's-t-test, and Regression analysis. Results: Serum FSH (p<0.01), LH (p<0.005) and Estradiol (p<0.001) were significantly higher while prolactin (p<0.02) and testosterone (p<0.001) were significantly lower among pesticides exposed farmers than non- exposed subjects. Some 34/84 (40.5%) of the pesticides exposed farmers had serum testosterone levels below the lower limit of the reference range. Those with low testosterone levels (p<0.001), also had FSH (p<0.05), LH (p<0.001) and Estradiol (p<0.002) significantly lower than those with normal testosterone levels. The sperm count among pesticides exposed farmers; total motility and percentage morphology were significantly lower than non-pesticides exposed subjects. Some 14/84 (16.7%) of the pesticides exposed farmers had sperm count below 15 million/mL (oligozoospermia). More than 70% of the farmers were not aware of the reproductive health risks associated with pesticides and only 23.8% of the farmers were using protective devices. Conclusions: Deliberate efforts to improve awareness, knowledge, personal hygiene, and interventions necessary to lessen both pesticides exposure and health risks by adopting safe practices are suggested.

        Support vector ensemble for incipient fault diagnosis in nuclear plant components

        Abiodun Ayodeji,Yong-kuo Liu 한국원자력학회 2018 Nuclear Engineering and Technology Vol.50 No.8

        The randomness and incipient nature of certain faults in reactor systems warrant a robust and dynamicdetection mechanism. Existing models and methods for fault diagnosis using different mathematical/statistical inferences lack incipient and novel faults detection capability. To this end, we propose a faultdiagnosis method that utilizes the flexibility of data-driven Support Vector Machine (SVM) forcomponent-level fault diagnosis. The technique integrates separately-built, separately-trained, specializedSVM modules capable of component-level fault diagnosis into a coherent intelligent system, witheach SVM module monitoring sub-units of the reactor coolant system. To evaluate the model, marginalfaults selected from the failure mode and effect analysis (FMEA) are simulated in the steam generator andpressure boundary of the Chinese CNP300 PWR (Qinshan I NPP) reactor coolant system, using a bestestimatethermal-hydraulic code, RELAP5/SCDAP Mod4.0. Multiclass SVM model is trained withcomponent level parameters that represent the steady state and selected faults in the components. Foroptimization purposes, we considered and compared the performances of different multiclass models inMATLAB, using different coding matrices, as well as different kernel functions on the representative dataderived from the simulation of Qinshan I NPP. An optimum predictive model - the Error CorrectingOutput Code (ECOC) with TenaryComplete coding matrix - was obtained from experiments, and utilizedto diagnose the incipient faults. Some of the important diagnostic results and heuristic model evaluationmethods are presented in this paper

        Comparison of Storability and Quality of Sweet Pepper (Capsicum annum L.) Grown in Two Different Hydroponics Media

        Abiodun Samuel Afolabi,In-Lee Choi,Joo Hwan Lee,Kwon Yong Beom,Ho-Min Kang 한국포장학회 2022 한국포장학회지 Vol.28 No.1

        This study compared the effects of cocopeat and perlite growth media on the storability and quality of sweet pepper fruit stored using modified atmosphere packages (MAP) and carton boxes. The fruits were stored at 8oC for 35 and 30 days, respectively. Perlite-grown fruits had a significantly lower size at harvest due to the medium’s inability to hold plenty of water during the growing stage. Contrary to what is expected for small fruits, the result shows box-stored perlite-grown fruits to have lower weight loss and a longer shelf life than cocopeat-grown fruits, while MAP fruits have indifference. Perlite fruits also had a higher quality in terms of dry matter, soluble solids, and vitamin C, while box-stored fruits had a better visual quality. As expected, respiration and ethylene production rates were high, and fruits had similar after-storage firmness values. Based on the findings, perlite-grown sweet pepper fruits may have a better quality and give preference in a box storage condition.

        Tax Compliance Attitudes in Africa: How Important Is Natural Resource Endowment?

        Abiodun Adewale Adegboye,Adeniyi Olanrewaju Adekanla 중앙대학교 경제연구소 2023 Journal of Economic Development Vol.48 No.2

        The effectiveness of Africa's tax systems may have been influenced by a number of variables that differ greatly from one country to another. Based on the effectiveness of tax administration and the endowment of natural resources, this study investigates the factors that influence tax compliance attitudes. The results highlighted the factors influencing one's likelihood to pay taxes or not using survey data from Afrobarometer. Although there is no discernible correlation in countries with poor tax efficiency, there is strong evidence for it in regions with high tax efficiency. The governance quality and natural resource rent have a complementary effect on tax compliance. Particularly, countries with low tax effectiveness might benefit from a focus on the factors that influence tax compliance, such as trust in the government. In the nations with high tax effectiveness, policy change on tax compliance also has a focus on reducing tax complexity, trust, and income.

      • An African Christian Theological Evaluation of God in Selected Major Religions

        ( Abiodun Aderele ) 삼육대학교 선교와사회문제연구소 2021 Asia-Africa Journal of Mission and Ministry(AAMM) Vol.24 No.-

        Worship is a reality in different religious contexts. It moves beyond the physical to the spiritual. Moreover, the scholars of religion have also tried to reconcile the one whom worship is directed to in various religions under the concept of “God” in religion. This paper followed harmonisations of the concept of God, which is termed to be the same for all religions by some and termed to different by others. So, it is necessary to use an evangelical Christian theological basis to evaluate the understanding of “God” in two major religions on the soil of Africa. This paper, therefore, introduces the topic, discusses the concept of God in African Traditional Religion, and explains the concept of God in Islam. Also, it critically and theologically evaluates the two worldviews through the lens of an African Christian theologian from an evangelical perspective. This study concludes that several characteristics such as love, Trinity and freewill concerning human beings differentiate God in Christianity from God in Islam and African Traditional Religion.
