The study on quality assessment of surface waters and sediments of a hydrocarbon contaminated mangrove wetland that is between longitude (6o45’, 6o51’)E and latitude (4o35’, 4o48’)N in the Niger Delta, Nigeria was carried out using standard methods. The data obtained indicated variability in most of the quality characteristics in the sediments and surface waters of the area under investigation. Of all the parameters studied, it is only pH value 7.00.13, sulphate ions - 367.9366.2mg/l, calcium ions - 0.9110.630meq/100ml and magnesium ions - 3.2442.350meq/ml that are significantly higher (P<0.05) in the surface water than in the sediments 4.40.65, 20.79.5mg/kg, 0.2620.084138meq/100g and 0.7360.138meq/100g respectively. Apart from salinity, all other parameters where significantly higher in the sediments than in the surface waters, seasonally (dry and wet) there were significant differences (P<0.05) of most of the parameters in both media apart from pH value and potassium ions in the surface water and phosphate and nitrate ions in the sediments. The results of the study have shown that most of the parameters in the sample stations are higher than the control station, related studies and some regulatory limits. The stations with higher values of these parameters are mostly stations with more anthropogenic activities. There is therefore need for continuous monitoring to be carried out to ascertain the long-term impact of anthropogenic inputs to take remedial measures so as to ensure the health of aquatic life.
The porous nature of a hard carbon material has been synthesized using one of the familiar methods of nanotechnology. Those materials were taken from renewable material of fruit peels, especially, banana peels-Musa Balbisiana

Over the years, more than 600 clones and 266 open-pollinated seed families have been introduced into India from different parts of the world. The best clones after nursery and field screening were selected for control crossing using Line × Tester design with 8 parents to develop superior hybrids.
Research work was conducted to examine the characteristics of piezoelectric crystal pressure transducer for fluid in a pipe system. Mathematical model was developed in this case to monitor, predict and simulate the effect of time on pressure system, density of the system, velocity of the system and voltage of the system using Matlab computer language programme.
The present study was designed to evaluate urban air pollution status and the effects of fine particulate matter (PM2.5) on mice lung inflammation under controlled exposure conditions.
For a classical computer, the elements of computing circuits release heat according to Landauer’s principle whenever they loses an information during a computing process. However, quantum computers do not emit such heat because there is no information loss in quantum computing due to the reversibility of its processes.
This work investigates the performance statistics of event based data delivery model for Agro-ecological Sensor Network with multiple sink nodes. Agro-ecological sensors improve the task of farm management and helps in reduction of environmental as well as economical production cost.
