Effect of Maize (Zea mays L.) on Human Development and the Future of Man-maize Survival: A Review

Abstract: From the hands of Olmec, Maya including Inca from whom Corn evolved to all parts of the globe, maize has provided Man with Nutritive, Medical, Pharmaceutical, Industrial, Domestic, Economic including Research values. Corn stands at the center of Mankind, providing Humanity with raw materials for further survival and development. As the need for corn doubles, and as science further widens knowledge on the use/utilization of the crop, creating more avenue and approaches where corn grains, leaves, silk, stem, root and other parts of the plant can be transformed into countless products, then the need to devote more hectares of land to Corn production becomes imperative. Corn has been shown to have the potential to be used in combating global food insecurity, as an indicator-crop for soil fertility assessment and as a commercial cash crop for income generation. Production of Corn has reduce poverty rate and raise standard of living of farmers, especially in the poor/developing countries.

The influence of solar power and solar flux on the efficiency of polycrystalline photovoltaics installed close to a river

Abstract: There is an increasing focus on utilizing the renewable energy resources, especially solar energy as the fossils are expected to deplete in near future. Solar Photovoltaics have remained of particular interest because of their relative lower overall efficiencies .Most researchers are trying to enhance the overall performance of Solar Photovoltaic and trying to study factor that may possible lead to an increase in the overall performance of a Solar Photovoltaic Panels. A thorough investigation was carried out to study the influence of solar power and solar flux on the performance parameters of Photovoltaic (Polycrystalline). The data used in the research was obtained by in-situ measurement approach using an SM206 precision digital solar power meter, a digital solar flux meter, and an M890C + digital Multimeter. The result obtained shows an interesting correlation for current, efficiency and solar power as well as for solar flux which indicates that high solar power and solar flux positively enhances the performance of the photovoltaic. The results also reveal that once the solar power or solar flux reaching the photovoltaic exceeds 200W/m 2 or 20Klux, the voltage from the photovoltaic approaches maximum and remains fairly stable irrespective of the amount of solar power or solar flux reaching the photovoltaic. The data collected for three months, July, August and September shows prediction efficiency of 87 %, 63% and 71% at 11:30am, 12:30 pm and 10:30 am respectively.

Potential of Moringa oleifera as nutrient–agent for biofertilizer production

Abstract: The results of this research reveal Moringa oleifera to be an effective nutrient-agent for biofertilizer production. Herein, plant analysis data indicate Moringa to be a good nutrient carrier of elements that can enhance effective and productive cultivation of crops, while in-turn maintaining soil fertility status.

Sustainable low-income housing and practicable minimum design standards in bayelsa state, nigeria.

Abstract: This sustainability of low-income housing in Nigerian cities vis-a-vis building regulation/minimum design standards is discussed in this paper. Thus, the papers appraised the practicability of the existing minimum housing standards regarded as a borrowed idea in relation to the socio-economic realities of the low-income urban dwellers. Data collection involved both qualitative and qualitative data from the private owners and rentals /users of low-income housing available in the study area. This study employs non-probability sampling designs which are a combination of purposive and expert sampling techniques. Sample frame of 20 housing units in the low-income neighbourhood and respondents were selected for in-depth study and interview, while only 15 key informants were interviewed. This was complemented with 1440 questionnaires distributed across the low-income residential neighbourhoods. The quantitative data were analysed using both simple descriptive and inferential statistics; this was done using the Minitab Statistical Package (MSP), Version 14 and Statistical Package for Social Sciences (SPSS) version 22 which involved the calculation of the Chi-Square test while the qualitative data were analyzed using content analysis from where themes and conclusions were drawn. Findings show that the existing housing standards is not realistic and the low-income urban dwellers cannot afford the conventional standard houses because it requires high construction cost, building material and labour due to their poverty level. The paper further re-developed a proposed minimum housing standard which is practical and affordable to the urban poor. Finally, it recommended that housing standards should be based on the concept of “low and upgradable” which is relaxed and flexible for the low-income group while also encouraging incremental housing approach including the provision of basic infrastructure services by the government to enhance liveability.
