Assessment of Soil Thermal Properties in a Tropical Environment: Ile Ife and Ibadan
(Journal of Faculty of Science, University of Ibadan, Ibadan, Nigeria., 2011) Otunla T.A.; Oladiran E.O.
Soil thermal properties are crucial parameters that affect soil heat flux. Time series of soil temperature, soil moisture content, and rainfall and soil heat flux were measured at two tropical locations in West Africa during the transition from dry to wet season, and at the peak of rainy season in July. The data were analyzed to estimate soil thermal diffusivity, thermal inertia and volumetric heat capacity. The thermal properties were clearly related to soil moisture (and thus rainfall) throughout the measurement period. The modeled soil heat flux using the soil thermal properties compared favorably with the measured soil heat flux.
Assessing the Performance of Global Solar Radiation Empirical Models at a Sahelian Site, Sokoto, Nigeria
(The Nigerian Association of Mathematical Physics, 2015) Otunla, T.A.; Kolehaje, O. T.
In the region where solar radiation data are scarce, the next alternative method is to use solar radiation models to estimate the data needed for some applications such as simulation of crop performance and the design of solar energy conversion devices. In this paper, the validations of fifteen models for estimating monthly mean daily global solar radiation on the horizontal surfaces were conducted at a location in salielian region where there is great potential for solar energy utilization in electricity generation and irrigation. Evaluations of these models were carried out by using the Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE) and t-test. Three of these statistical performance indicators were combined to generate rank score for each model. Temperature based models made the rank of the best three during the wet season. On the annual scale and in the dry season, temperature variations and humidity were combined with sunshine duration to get the best rank of I to 3.
Willingness of tobacco retailers in Oyo State to participate in tobacco control programmes
(E.U. European Publishing, 2018) Uchendu, O.; Adebiyi, A. O.; Adeyera, O.
INTRODUCTION Tobacco control strategies have not incorporated retailers, despite being the focus by the tobacco industry to promote its products. Few studies exist on their possible roles in tobacco control. This study, therefore, assessed retailer awareness of tobacco control laws and willingness to be involved in control activities.
METHODS A cross sectional study was carried out on all 218 tobacco retailers in Ibarapa Central and Ibarapa East Local Government Areas of Oyo State. The willingness of tobacco retailers to participate in tobacco-use control was evaluated using a questionnaire.
RESULTS The majority of the respondents were females (95%), and 30-39 years old with respect to age. Almost two-thirds (65%) of the respondents reported the sale of tobacco as a profitable business, and a third reported that their income would decrease if they stopped tobacco sales. Up to 35% of retailers were aware of laws restricting smoking in public places and 45% aware of a ban on the sale of tobacco products to minors. Retailers were willing to: support anti-tobacco legislations (84%), counsel smokers to quit smoking (84%), and display anti-tobacco messages in their shops (77%).
CONCLUSIONS The sale of tobacco products is a profitable venture for retailers.
Willingness to participate in tobacco control was high among the retailers. There is a need to raise awareness and co-opt tobacco retailers as change agents in tobacco control efforts.
A Rural-Urban comparison of the prevalence and factors associated with unintentional home fall injuries in South Western Nigeria
(College of Medicine, University of Ibadan, 2018) Uchendu, O. C.; Owoaje, E. T.; Iken, O. F.
Background: Unintentional home fall injuries contribute to the morbidity and mortality burden in developing countries. Rural-Urban variation on the burden of unintentional home fall injuries in Africa is poorly documented. We compared the prevalence and factors associated with unintentional home fall injuries among household members in rural and urban areas of South Western Nigeria.
Methods: We conducted a community-based cross sectional survey using a three-stage cluster sampling technique to select 4433 individuals from 1015 households from selected settlements in a rural and urban Local Government Areas (LGAs). A structured questionnaire was used to obtain information on household members’ characteristics, individual injury experience and nature of injury experienced. Chi square test and logistic regression were used to determine factors associated with unintentional home fall injuries.
Results: Overall, the incidence of unintentional home falls injury was 171/1000 per year with a significantly higher incidence in the urban (195/1000 per year) compared to rural (150/1000 per year) areas. The odds of experiencing unintentional home fall injuries was 1.47 times higher in household members living in urban areas compared to their rural counterparts (OR=1.47; 95%CI: 1.13-1.92).
Conclusion: The burden of unintentional home fall injuries is high with a significantly higher urban preponderance. Enforcement of building codes to ensure safety of the home environment especially in urban areas is also recommended for resource poor countries like Nigeria.
Willingness to uptake breast cancer screening among rural women in Southwestern Nigeria
(Society for Public Health Professionals of Nigeria (SPHPN), 2017) Uchendu, O. C.; Olabumuyi, O. O.; Idowu, S.; Adamu, D.
Background: The mortality attributed to breast cancer remains high especially among rural dwelling women in low-income countries. Late diagnosis that may be as a result of poor knowledge and nonutilization of available screening has been implicated in the high mortality burden. Enhancing access to and uptake of breast cancer screening will reduce the cancer burden.
Objectives: This study was conducted to assess the willingness to uptake breast cancer screening among rural women in South Western Nigeria. Factors associated with willingness to uptake breast cancer screening were also determined.
Methods: A community-based cross-sectional design using multi-stage sampling was used to select 920 women in Igbo-Ora, South Western Nigeria. An interviewer-administered questionnaire was used for data collection. Data was analysed using SPSS at a 5% level of statistical significance.
Results: The respondents were aged 15 to 86 years with 795 (86.4%) being within the reproductive age group. Of total respondents, 546 were aware of breast cancer of which 171 (31.3%) had good knowledge about the symptoms of breast cancer. Of the 834 respondents who had never screened for breast cancer,
651 (78.1%) were willing to screen. Respondents within the reproductive age group and those that knew someone with breast cancer had odds of 2.7 and 2.5 respectively of being willing to uptake breast cancer screening. (OR=2.9; 95% CI=1.8-5.1 and OR=2.5; 95% CI 1.2-5.7)
Conclusion: Although the knowledge of breast cancer and the awareness of screening methods among women in rural area is low, their willingness to get screened remains high. The use of survivors as well as survivor relatives should be considered during community-based health programmes aimed at improving uptake of screening among this population.
