This work concerns the evaluation of the performances of some selected rain attenuation models at two different locations in Lagos, Nigeria at 12 and 40 GHz. Scarcity of rainfall data in the tropical regions resulted in abysmal research efforts into the causes and solutions to satellite signal outages, this was further exacerbated by the convective tropical rain...

Better understanding of variations in seed traits and seedling vigor in various populations of a given species is vital for appropriate nursery and tree planting technology. The main objective of this study was to identify better provenance for indigenous trees by testing seed germination and seedling traits. Seeds of six indigenous trees (Vachellia abyssinica,...

The identification of anomalous elemental concentrations and the prediction of their dispersal pattern play a key role in geochemical exploration. Stream sediments are important focus in this aspect. Nine (9) sediment samples collected from Ishakare and Alatan Streams in Akungba-Akoko were subjected to grain size and inorganic geochemical analyses in order to... Continue here
Our environment has been compromised through unwise and unplanned use of land, air, and water exacerbated by population increase, science and technology so much that some areas in Nigeria no longer support life as it ought to. Continuous impacting negatively on the environment to afford us the luxury building construction can afford, eventually leads us to short... Continue here
This research was carried out to evaluate the impact of dumpsite and farming methods (anthropogenic Activities) on wetland soil qualities. Soil samples were collected from three strategic locations in Irri and Uzere communities at Delta State of Nigeria, and a reference station (control) about 5 km away from the study site. The sampling was done at the end of the... Continue here
