A Study of Hyperfine Interactions of Peroxy Radicals in Irradiated PE Copolymer at Low Temperatures
Abstract: Hyperfine interactions occurring around the magnetic environment of peroxy radical are investigated by electron spin resonance (ESR) technique. For this purpose, ESR spectra are recorded in the temperature range of 77 to 300 K. ESR spectra at 77 K possess some hyperfine structure together with peroxy doublet; while at high temperatures only peroxy doublet is observed. Hyperfine parameters like g-values, peak to peak separation, spread are calculated and their temperature …

Comparative Analyses of Select Microbial Growth Inhibited Rate Models
Abstract: Food waste is a complex substrate comprising of different mixtures of chemical compounds. The growth rate of micro-organism in such environment will experience inhibition. Consequently, the Monod’s model will not be able to describe the growth rate of its bacteria. The Aiba’s, Andrews and the Haldane’s growth rate models that are accounts for growth rate of bacteria with inhibition were compared. To do this, seven different batch experimentations; each with …

Mathematical Modelling of the Effect of Functional Parameter on the Biodegradation Rate of Hydrocarbons
Abstract: The discovery of oil as a potential source of energy did not come without its attendant problems. Continuous degradation of our environment and increased carbon footprint is a negative consequence of global industrialization. However, microbes are known to consume such hydrocarbon in an attempt to restore the environment to its original state. These microbes depend on several factors-one of which is temperature- to function effectively. In this work, we have …
