Nigerians Perspectives on Covid-19 Pandemic and How It Affects Their Lifestyle and Financial Status (Published)
Covid-19 is a viral disease that originated from Wuhan province of China. The virus has rapidly crossed borders, infecting and killing people in many countries including Nigeria. Undoubtedly, the pandemic has massive impact on the activities of Nigerians, including social lifestyle and income. The age-long communal behavior of Nigerians, like attendance to religion gatherings, ceremonies, and sports, has been hampered due to covid-19 pandemic. Also, due to this pandemic, Nigeria´s economy has declined drastically. This study was conducted to understand the perspective of Nigerians about Covid-19, and how it affected their lifestyle and financial status. Method: An online survey was conducted using the combination of few open ended and closed ended questions to gather data from a total of 325 respondents in Nigeria. Results: Majority of the respondents had adequate knowledge about the Covid-19 infection, its preventive measures, and its mode of transmission. Furthermore, over half of the respondents admitted that the pandemic has adversely affected their social lifestyle and financial status. Conclusion: There is need for provision of financial assistance and distribution of palliatives to all Nigerians during this pandemic. The government should also ensure the safety of all citizens, as social vices increase amidst the pandemic. A policy against increment of price of commodities should be established and implemented.
The occurrence of interference that causes partial loss of intelligence in air navigation signal is largely dependent on total environment around radio navigation aid systems (navaids). Directional antenna polar diagrams can be measured in horizontal or vertical mode. Usually the horizontal mode means a rotation of the test antenna in the electric or E-Plane and magnetic or H-plane for the vertical mode. This paper compares the effect that selected roofing materials have on Navaids transmission distance. To achieve this, a transmitter, a receiver and a computer to measure signal level transmitted through roofing materials at a frequency of 9.4GHz are used. The study considered effects of decra, iron, steel, aluminum, plastic and clay materials on navaids transmission distance. The study found that effects of roofing materials on transmission distance varied depending on the type of selected roofing material. Signals via plastic materials decreased with distance as those via aluminum increased with distance. However the overall effect of roofing materials on transmission distance was not significant since the received signal was within the recommended strength. Also the materials had path loss exponent factors of between 3.0 to 3.7 which meant that the rate at which the signal was propagated through these structures was significantly slower than in free space where exponent factor is 2. It is recommended that studies be directed in conducting experiments in open fields and factoring in sources of variability arising from the environment so as to relate to the actual scenario of flight navigation
