Gas Flaring in Nigeria: What Can be Done to Curb It by Cynthia Ohaeri

GAS FLARING in Nigeria, the burning of natural gas associated with oil extraction, has been a prevalent practice. Natural gas brought to the surface, especially where there is no infrastructure to put this “associated gas” to productive use is burnt for disposal thus making it a wasteful and generally polluting practice. An economy that promotes carbon emission through flaring wastes valuable energy products, increases health disparities and fuels climate change, a far-cry from the Glob...

Root Chip for Growth and Imaging of Arabidopsis Plants

  We describe a microfluidic platform that can be used to study the hydroponic growth of Arabidopsis plants with high-resolution visualization of root development and root-pathogen interactions. The platform comprises a set of parallel microchannels with individual input/output ports, where 1-day old germinated seedlings are initially placed. Under optimal conditions, a root system grows in each microchannel and its images are recorded over a 198-h period. Different concentrations of plant g...

Magnetic Field effects on Saccharomyces cerevisiae for fermentation in bioethanol production

In this study, two sets of experiments were conducted in order to investigate the impact of static magnetic fields on the growth and ethanol production of Saccharomyces cerevisiae. The first experiment ran for 25 hours with a 2% dextrose loading rate, while the second ran for 30 hours with a 6% dextrose loading rate. The magnetic fields used were homogeneous and non-homogeneous, with strengths of 100 mT and 200 mT, respectively. The results showed that the homogenous magnetic field had no sig...
