The modelling of chemical and biochemical systems is highly dependent on the reaction network of the system. A reaction network should contain all the reactions which can occur in addition to the species involved. However in many cases there will be reactions occurring which are missing from the network. These are called gaps (Reed et al., 2003; Duarte et al, 2004) and occur because the databases of reactions used to build them are incomplete. The main aim of this work is to identify all the reactions which can occur in a given system including the unknown ones. This is accomplished through a

Pyrolysis is one of the thermochemical techniques to convert biomass into bio-oil, bio-char and gaseous products. This work has focused on modelling the kinetic behaviour of cellulose, which is the most abundant component in any type of biomass, under slow and fast pyrolysis conditions and in the presence of inorganic species using Distributed Activation Energy Model (DAEM). In addition, cellulose pyrolysis product yield has been estimated using Computational Fluid Dynamics (CFD) modelling framework.

Len Lye's aesthetic requirements stipulate that the vibratory blade form of the scaled sculpture must be geometrically similar to the original work and that static similarity should exist between the original and the scaled blades.

Resumo:
Ag thin film growth on ZnO substrates has been investigated theoretically using multi-timescale simulation methods. The models are based on an atomistic approach where the interactions between atoms are treated classically using a mixture of fixed and variable charge potential energy functions. After some preliminary tests it was found that existing fixed charge potential functions were unreliable for surface growth simulations. This resulted in the development of a ReaxFF variable charge potential fitted to Ag/ZnO surface interactions. Ab initio models of simple crystal structures and surface
