Introduction: Over the last decade, exposure to electromagnetic waves due to base station antennas has increased. This study was planned to evaluate the effects of different electrical field strengths with 950 MHz waves of the GSM mobile phone system on the excitatory postsynaptic potentiation (EPSP) slope of the dentate gyrus long-term potentiation (LTP). Material and Methods: Twenty four naiv...

The place of information in addressing market access and participation limitation, which hinders farmer’s welfare and poverty reduction efforts in many developing countries, cannot be over-emphasized. This study therefore examined the use of mobile phone in the marketing of food crops among farming households in rural south east, Nigeria. A multi stage sampling procedures was used in the select...

Introduction:  The  use  of  mobile  communication  systems  has  dramatically  increased  over  the  past  decade. Although many studies have been performed to determine the effect of radio frequency (RF) but  less attention has been paid to the possible biological impact of exposure to extremely low frequency  (ELF) components.   The objective of this study is two folds. One is to design the ...
