Mineral composition of non-conventional leafy vegetables

Abstract: Six non-conventional leafy vegetables consumed largely by the rural populace of Nigeria were analyzed for mineral composition Mineral contents appeared to be dependent on the type of vegetables Amaranthus spinosus and Adansonia digitata leaves contained the highest level of iron (384 mg/100 g and 306 mg/100 g dw, respectively) These values are low compared to those for common Nigerian vegetables but higher than those for other food sources All the vegetables contained high levels of calcium compared to common vegetables, thus they could be a rich source of this mineral Microelement content of the leaves varied appreciably Zinc content was highest in Moringa oleifera, Adansonia digitata and Cassia tora leaves (255 mg/100 g, 224 mg/100 g and 209 mg/100 g dw, respectively) while the manganese content was comparatively higher in Colocasia esculenta The concentrations of the mineral elements in the vegetables per serving portion are presented and these values indicate that the local vegetables could be valuable and important contributors in the diets of the rural and urban people of Nigeria The mean daily intake of P, Mg, Ca, Fe, Cu and Zn were lower than their recommended dietary allowances (RDAs) However, the manganese daily intake was found not to differ significantly (p = 005) from the RDA value

Evaluation of mineral elements and ascorbic acid contents in fruits of some wild plants.

Abstract: The fruits of some wild plants were examined for their contents of mineral elements and ascorbic acid. High levels of ascorbic acid were found in fruits of Sclerocarya birrea (403.3 mg/100 g) and Adansonia digitata (337 mg/100 g). In nine of the fruits examined, the mineral contents (Ca, P) were comparable with average values found in common fruits. The iron contents were however 2-5 times higher than the values for common fruits.

The Niger Delta wetlands: threats to ecosystem services, their importance to dependent communities and possible management measures

Abstract: The Niger Delta wetlands are changing rapidly, raising concern for the wetlands' health and for communities relying upon its ecosystem services. Knowledge on ecosystem service provision is important for effective ecosystem and livelihoods management, but is currently lacking for the Niger Delta. We synthesised literature and used the ‘Drivers–pressure–state–impact–response’ (DPSIR) framework to structure information on changes in the wetlands' ecosystem services and implications for dependent communities. The wetlands' ecosystem services are being eroded through oil and gas exploration, dredging, invasive plant infestation and wetland reclamation. This is exacerbated by rising demand for oil, population growth and weak governance. Mass fish migration, water pollution and reduction of wetland area are also evident, impacting ecosystem services and traditional livelihood systems. This has caused poverty; people have to buy goods that previously could be obtained from the wetlands. Effective wetland manageme...

Design, development, and evaluation of a mobile learning application for computing education

Abstract: The study focused on the application of the design science research approach in the course of developing a mobile learning application, MobileEdu, for computing education in the Nigerian higher education context MobileEdu facilitates the learning of computer science courses on mobile devices The application supports ubiquitous, collaborative, and social aspects of learning among higher education students Moreover, the application eases access to learning resources The paper first describes analysis, design, and implementation activities related to the development of MobileEdu Also, the paper deliberated on the characteristics and scope of the adherence of MobileEdu to the traits and ideas of design science research To evaluate MobileEdu in a real-life learning setting, experiment was conducted with 142 third-year undergraduate students in a Nigerian university Besides the learning achievement of the students using MobileEdu, the study examined the impact of MobileEdu on students' attitudes toward studying in a system analysis and design course Experimental data were collected from pre- and post quizzes, interviews, and a questionnaire administered to students The results of the evaluation are encouraging and showed that the MobileEdu application has a potential to improve students' learning achievements In addition, the pedagogical experiences of students were mostly positive and students' attitudes toward the system analysis and design course through MobileEdu was better than those of students who studied the course via traditional methods Finally, the study offered suggestions for how to implement effectively a mobile learning-supported course in computing curriculum
