Abstract: Spectral depth analysis over parts of Nasarawa area was carried out using high resolution aeromagnetic data to determine the depth to bottom of magnetic sources, to enable build up a subsurface picture of basement configuration and possible sediments distribution that promote hydrocarbon exploration in the area. The study revealed one and in most cases two source model, these are the deep magnetic anomaly sources and the shallow magnetic anomaly sources. The deep sources anomalies vary between 2.23km and 5.11km with an average depth of 3.05km and this represents the magnetic basement depth. The shallow anomaly sources vary from 0.07km to 0.42km with an average of 0.21km and this may be regarded as the magnetic intrusions into the sediment, probably through the magmatic activities. The revelation from this study of 3.05km magnetic basement depth at the southern part of the area is synonymous to depth of Cretaceous sediment, which is very significant to hydrocarbon generation potential in the area. The result shows the graben nature and indicated the existence of a deeper sub basin in the area. The central and south-western parts with higher sedimentary thicknesses are the most probable sites for hydrocarbon accumulation.

Abstract: The literature suggests that plants are able to grow in the absence of gravity, and NASA has a plan to cultivate plants on Mars. Thus, the aim of this research was to study the germination and growth of green beans at differing levels of gravity from 0.5G to 3G. Pseudo gravity has been used to study the growth and germination of the green beans under different gravity levels. The results showed that under high gravity the green beans were able to germinate but were unable to grow. Under low gravity the green beans were able to both germinate and grow. However, due to the limitations of the authors’ apparatus, the behavior of green beans under lower gravity levels than 0.5G could not be investigated. Finite element modeling was used to study the stems of the green beans at different gravity levels. The result from the FEM is correlated with the experiment but it did not take the angle from the horizontal line as the actual germination of the green beans. However, it shows that under high gravity the stems of the bean sprouts were not able to resist the force of gravity. Thus, the plants might be unable to germinate and grow on new planets of larger size.
