Classroom science with everyday life: A means for improving performance in sciences and national development in Nigeria

Science is a body of knowledge about the natural world (the environment) that is testable, verifiable or falsifiable by using organized scientific methods and skills. It has been generally asserted that the rate of development of any nation depends on the level of her citizens’ scientific literacy and competence in science process skills. The methods of teaching/learning science in Nigeria have hardly provided for...

Population move on Rajasthan: Regional analysis

The physiography of Rajasthan is not suitable for agricultural activity. Most parts of Rajasthan are sandy regions and Aravalli Mountain, which is a barrier for agriculture. Eastern part of Rajasthan is covered with plain soil but this region is also not suitable for agriculture. This is the reason why Rajasthan experienced a large proportion of out-migration from its different physiographic regions. The present...

Cadmium-induced toxicity and antioxidant enzyme responses in tissues and organs of African catfish (Clarias gariepinus)

Juveniles of Clarias gariepinus were exposed to different concentrations of cadmium chloride for 96 h under laboratory conditions using static bioassays with continuous aeration to determine its mean lethal concentration (LC50), biochemical alterations, bioaccumulation and histological pattern in a sub-lethal toxicity test. The median lethal concentration (LC50) at the end of the acute toxicity was 120.2 mgL-1. Also the...
