the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Although most flowering plants are polyploid, little is known of how the meiotic process evolves after polyploidisation to stabilise and preserve fertility. On wheat polyploidisation, major gene ZIP4 on chromosome 3B duplicated onto 5B diverged (TaZIP4-B2). TaZIP4-B2 was recently shown promote homologous pairing, synapsis crossover, suppress homoeologous crossover. We therefore suspected that t...
