In a previous series of 3 articles in this Journal we have looked at the situation when the aquifer desaturates while the riverbed (clogging layer) remained saturated. However it is quite possible that the riverbed itself will desaturate, particularly if the river stage is low a...

The concentration of NORMs and some toxic heavy metals in some nuts and seeds commonly consumed in the south-western states of Nigeria were investigated. The analysis was done with NaI(TI) spectrometry and Inductively Coupled Plasma (ICP) respectively. The concentration of 226Ra,...

Aims: The aim of this study is to extend the formula of Newman–Janis algorithm (NJA) and introduce the rules of the complexifying seed metric. The extension of NJA can help determine more generalized axisymmetric solutions in general relativity. Methodology: We perform the extend...

Ferrite are conventional materials used for microwave absorption, however, they are expensive, constitute health hazard and pollutes the environment. For these reasons, there is need to explore safe and environmental friendly materials that can serve as radiation absorbers and be...

This paper brings into attention a possible logarithmic connection between Einstein’s constant and the fine-structure constant, based on a hypothetical electro-gravitational resistivity of vacuum: we also propose a zero-energy hypothesis (ZEH) which is essentially a conservation...

Because there is additional space in which the observed three-dimensional Universe expands, it is believed that elementary particles move at the speed of light in full space in a vicinity of a hyper-surface of three-dimensional sphere that is our Universe. Any interpretation of a...

The time behavior of a wave packet, transmitted through a potential barrier, is investigated for all times assuming it to be initially located outside the asymmetric barrier. The survival probability of the initial state, which characterizes the decay of the unstable quantum syst...
